fix(#1332): verdict fixture 2 - herestring, not printf-pipe into grep -qF

pipefail-early-exit.test.mjs (static scan) flagged the fixture-2 check as a
pipe into an early-exiting consumer; the sibling at fixture 1 already uses
the herestring form. Red reproduced locally (one scan entry, exactly the
flagged line), green after matching the sibling; verdict 4/4 and glyph 6/6
re-run green.

+## Pi Persistent Goal Loop (#1150)
+
+### Problem and objective
+
+A Pi agent can stop after a plausible-looking answer even when the operator's broader objective is
+not complete, and ordinary compaction can weaken or omit the original objective. Mosaic needs an
+optional, operator-controlled goal loop that keeps a Pi session oriented, checks progress at native
+lifecycle boundaries, and resumes work until completion is verified or a bounded safety state is
+reached.
+
+The objective is a Mosaic-owned Pi extension deployed from the framework into
+`~/.config/mosaic/runtime/pi/`. It must not install into or depend on `~/.pi/agent/extensions/`.
+
+### Scope
+
+#### In scope
+
+1. `PGL-REQ-01`: The framework SHALL ship a dedicated Pi goal extension under
+   `packages/mosaic/framework/runtime/pi/`, seed it under `$MOSAIC_HOME/runtime/pi/`, and make
+   `mosaic pi` load it alongside the core Mosaic extension when present.
+2. `PGL-REQ-02`: `/goal` SHALL support setting a goal plus status, pause, resume, cancel, and help
+   operations without silently replacing an active goal.
+3. `PGL-REQ-03`: Active branch-specific goal state SHALL be persisted in Pi custom session entries,
+   restored on session start and tree navigation, and never rely on a compaction summary as its
+   source of truth.
+4. `PGL-REQ-04`: A hidden goal contract SHALL be injected through Pi's `context` event before every
+   model request so it remains effective across tool turns, retries, and post-compaction requests.
+5. `PGL-REQ-05`: The harness SHALL inspect every `turn_end` and successful `session_compact` event.
+   A structured terminating goal-report tool SHALL capture `continue`, evidence-bearing `achieved`,
+   or `blocked` status without requiring a redundant model turn.
+6. `PGL-REQ-06`: An achievement claim SHALL remain provisional until a second consecutive
+   evidence-bearing verification report. Any continuation report or successful compaction during
+   verification SHALL reset the verification sequence.
+7. `PGL-REQ-07`: Continuation SHALL be initiated at safe lifecycle boundaries, primarily
+   `agent_settled`; manual compaction and restored active sessions may schedule a deferred idle
+   continuation without re-entering compaction handlers.
+8. `PGL-REQ-08`: The loop SHALL have operator cancellation plus bounded turn and repeated-no-progress
+   limits. Exhausted or blocked goals pause rather than continuing indefinitely.
+9. `PGL-REQ-09`: Framework installation and update SHALL preserve normal manifest ownership: the
+   goal extension is framework-owned under `runtime/**`, while no goal extension or configuration
+   asset is created or modified under the operator's main Pi configuration. Pi remains the owner of
+   its native session files used by `appendEntry()`.
+
+#### Out of scope
+
+1. A mathematical guarantee that an arbitrary natural-language goal is semantically complete.
+2. Automatically executing user-supplied shell predicates or accepting executable validation code in
+   `/goal` arguments.
+3. Restarting Pi after process, host, or supervisor failure; the existing Mosaic fleet/runtime
+   supervisor owns process durability.
+4. Gateway, database, web UI, Discord, or cross-harness goal orchestration in this slice.
+
+### User and stakeholder requirements
+
+- An operator can start a goal from Pi and see its current phase, evidence, limits, and latest report.
+- The agent remains oriented after each turn and compaction until verified, paused, blocked,
+  exhausted, or cancelled.
+- Local testing uses a file under `~/.config/mosaic/runtime/pi/`; the feature never writes an
+  extension asset to `~/.pi/agent/extensions/`.
+- Framework updates deploy the same reviewed extension source through Mosaic's existing manifest
+  sync path.
+
+### Non-functional requirements
+
+1. **Safety:** bounded continuation, explicit cancellation, no arbitrary command execution, and no
+   completion without non-empty reported evidence.
+2. **Reliability:** serialized continuation scheduling, branch-aware restoration, compaction-safe
+   context injection, and stale-timer cancellation on session shutdown.
+3. **Performance:** no extra nested judge-model request on every turn; structured reporting uses the
+   active agent's final terminating tool call.
+4. **Observability:** Pi status/notifications expose phase and bounded counters without recording
+   credentials or hidden model reasoning.
+5. **Maintainability:** the state machine is deterministic and behavior-tested independently from Pi
+   provider/network access.
+
+### Acceptance criteria
+
+1. `AC-PGL-01`: A framework-sync fixture installs the extension at
+   `$MOSAIC_HOME/runtime/pi/goal-extension.ts`, and launcher tests prove both Mosaic Pi extensions are
+   emitted in deterministic order while absent optional files remain backward-compatible.
+2. `AC-PGL-02`: Command tests prove set/status/pause/resume/cancel behavior, active-goal replacement
+   refusal, and bounded input handling.
+3. `AC-PGL-03`: Lifecycle tests prove every turn is recorded, active context is injected on every
+   request, two evidence-bearing achievement reports are required, and `agent_settled` continues an
+   unmet goal without duplicate scheduling.
+4. `AC-PGL-04`: Compaction and restoration tests prove goal state survives, verification is reset and
+   rechecked after compaction, manual compaction continuation is deferred until idle, and tree/session
+   branch state is reconstructed correctly.
+5. `AC-PGL-05`: Limit tests prove max-turn and repeated-no-progress exhaustion stop autonomous
+   continuation, while pause/cancel/blocked states do not restart.
+6. `AC-PGL-06`: Focused tests, package typecheck/lint/test, repository quality gates, a local Pi load
+   smoke test from `~/.config/mosaic/runtime/pi/`, independent review, and terminal-green CI pass before
+   issue #1150 closes.
+
+### Constraints, risks, and assumptions
+
+- Dependency: Pi's extension API must continue to provide `registerCommand`, `registerTool`,
+  `context`, `turn_end`, `agent_settled`, `session_compact`, session custom entries, and terminating
+  tool results.
+- Risk: the working agent can overstate completion. Mitigation: structured evidence, a mandatory
+  second verification pass, explicit semantic limitations, and operator-visible reports.
+- Risk: an impossible goal can consume unbounded resources. Mitigation: hard turn/no-progress bounds
+  and paused terminal states.
+- Risk: automatic continuation can race compaction or session replacement. Mitigation: drive from
+  `agent_settled`, defer idle restarts, generation-check timers, and clear timers on shutdown.
+- `ASSUMPTION:` Two consecutive evidence-bearing reports are the initial local verification policy;
+  rationale: it provides a real recheck without doubling every turn's model cost. Future policy may
+  add independent or deterministic validators.
+- `ASSUMPTION:` Default limits are 40 turns and 6 repeated no-progress reports, configurable only by
+  bounded Mosaic environment settings; rationale: useful persistence with a finite autonomous budget.
+- `ASSUMPTION:` Documentation remains canonical in-repo for this slice; no external docs publication
+  is requested.
+
+### Testing and delivery intent
+
+Use TDD for the deterministic controller and lifecycle invariants. Test with fake Pi lifecycle
+objects first, then run a local load/smoke test from the deployed Mosaic path. Deliver source, tests,
+launcher wiring, framework/runtime documentation, user/developer guides, and sitemap updates in one
+reviewed squash PR to `main` with terminal-green CI.

+### Fleet git identity launch propagation (#1043)
+
+#### Problem and objective
+
+A fleet seat can have a registered per-agent Git credential while its launched runtime process lacks
+`MOSAIC_GIT_IDENTITY`. The credential resolver then cannot select the seat identity reliably, which
+blocks repository operations on fail-closed estates and can fall through to an unrelated identity on
+estates where that refusal is not active. The objective is to make Git identity a deterministic,
+roster-derived part of the generated launch projection and prove it reaches the launched process.
+
+#### Normative requirements
+
+1. `FGI-REQ-01`: Every generated fleet agent projection SHALL declare
+   `MOSAIC_GIT_IDENTITY=<MOSAIC_AGENT_NAME>`; a differing or unsafe identity SHALL fail closed before
+   tmux launch.
+2. `FGI-REQ-02`: The clean `/usr/bin/env -i` pane boundary SHALL pass every variable declared by the
+   generated projection, including `MOSAIC_GIT_IDENTITY`, to the launched runtime process.
+3. `FGI-REQ-03`: A behavioral integration test SHALL set-compare the complete generated projection
+   against the launched process environment. Source-text/string-presence assertions are insufficient.
+4. `FGI-REQ-04`: Verification SHALL include RED-first evidence and a delete-the-subject mutation that
+   removes Git-identity pane propagation and makes the behavioral test fail.
+
+#### Acceptance criteria
+
+1. `AC-FGI-01`: A launched seat process contains every key/value pair declared by its generated
+   environment projection, including the roster-derived Git identity.
+2. `AC-FGI-02`: Missing, unsafe, or split Git identity is rejected before a tmux session is created.
+3. `AC-FGI-03`: Focused launcher and generated-environment tests, repository quality gates,
+   independent review, and the required RED/green/R7 evidence are recorded before push.
+
+### Framework shell assertion portability (#1098)
+
+#### Problem and objective
+
+The blocking framework-shell chain can report that a pane command omitted `/usr/bin/env -i` even when
+`-i` matched successfully. A short-circuiting `grep -q` under `set -o pipefail` may close its pipe after
+the match and cause an upstream producer to exit with SIGPIPE, turning a valid semantic result into a
+nonzero aggregate pipeline. The objective is to inspect the captured NUL-delimited argv directly and
+make failures carry the observed records needed for diagnosis.
+
+#### Normative requirements
+
+1. `FSP-REQ-01`: The pane-boundary test SHALL validate an adjacent `/usr/bin/env`, `-i` argv pair from
+   the authoritative NUL-delimited tmux capture without a short-circuit pipeline whose upstream status
+   can override a successful match.
+2. `FSP-REQ-02`: Missing, reversed, or non-adjacent boundary tokens SHALL fail, while valid boundaries
+   SHALL remain valid regardless of trailing argv size, pipe capacity, process scheduling, or host/CI
+   utility implementation.
+3. `FSP-REQ-03`: A failed boundary check SHALL print stable indexed, shell-escaped observed argv records
+   before exiting nonzero; the fixture SHALL continue to contain generated non-secret launch data only.
+4. `FSP-REQ-04`: Verification SHALL include RED-first large-payload evidence, negative token-order
+   controls, the complete focused launcher suite, canonical Woodpecker CI, and independent review.
+
+#### Acceptance criteria
+
+1. `AC-FSP-01`: A large captured argv with adjacent `/usr/bin/env`, `-i` passes even when the former
+   `grep -q` pipeline returns nonzero from an upstream SIGPIPE.
+2. `AC-FSP-02`: Missing executable, missing flag, and detached/reversed flag fixtures return nonzero and
+   emit the indexed observed argv.
+3. `AC-FSP-03`: The focused suite passes on the development host and CI image, and the merged-main
+   Woodpecker pipeline is terminal green before #1098 closes.

+## Workspace placement guard hardening (#1174)
+
+### Problem and objective
+
+The Bash pre-tool guard must prevent Git checkouts and repository state from being placed under
+`$HOME` without refusing ordinary Git commands merely because a source, option value, branch name,
+or metadata mentions `$HOME`. A guard that over-blocks routine work is unsafe because operators
+will route around it.
+
+### Scope and requirements
+
+1. `WPG-REQ-01`: `git clone` and `git worktree add` placement SHALL be judged from their placement
+   operands, not from every HOME-shaped word in the command.
+2. `WPG-REQ-02`: Clone sources, references, templates, environment assignments, and non-placement
+   worktree metadata MAY resolve under HOME when all placement operands resolve elsewhere.
+3. `WPG-REQ-03`: Both attached and separate-value `--separate-git-dir` forms SHALL remain placement
+   operands and SHALL be refused when they resolve under HOME.
+4. `WPG-REQ-04`: Option classification SHALL account for Git's rule-generated boolean negations
+   without relying on an enumerable allowlist of flag spellings.
+5. `WPG-REQ-05`: Quote removal, escapes, shell command boundaries, redirections, and end-of-options
+   handling SHALL preserve existing fail-closed checkout coverage.
+6. `WPG-REQ-06`: Absolute placement aliases SHALL resolve shell-known HOME spellings, dot segments,
+   repeated separators, and existing symlink parents before the HOME boundary comparison.
+7. Relative targets whose effective path depends on the shell cwd are out of scope and tracked by
+   #1197.
+
+### Acceptance and verification
+
+1. Git's own option parser accepts each tested flag, including generated `--no-*` forms, while the
+   guard allows a HOME-valued source with an explicit safe destination.
+2. Equivalent clone and worktree fixtures cover rule-generated negations and remain discriminating
+   against the prior head where the defect existed.
+3. Real HOME destinations and both `--separate-git-dir` forms remain blocked, including placements
+   after shell command boundaries.
+4. The full hermetic guard suite, syntax/static checks, adversarial probes, independent review, and
+   terminal-green CI pass before merge.
+5. Any option-classification residual is documented with its deliberate failure direction.
+
+### Constraints, risks, and assumptions
+
+- Security and usability are co-equal: neither a placement bypass nor routine over-block is an
+  acceptable repair.
+- `ASSUMPTION:` The value-taking option surface exposed by the installed Git version is closed and
+  measurable through Git's own parser/help output; rationale: boolean flags are rule-generated,
+  while separate-value options have explicit grammar and must be classified as such.
+- Risk: a future Git release may add a new value-taking placement option. Mitigation: document the
+  chosen residual direction and pin every currently supported placement option in behavior tests.
+- Risk: a symlink can be replaced after pre-execution canonicalization. Mitigation: resolve every
+  existing parent physically and document the remaining inherent TOCTOU window; the worktree helper
+  remains the authoritative path-derivation mechanism, with atomic closure tracked by #1199.
+
+---
+
 ## Assumptions
 
 1. RESOLVED: **pgvector is sufficient** for semantic search at v0.1.0 scale (personal/family/team = thousands to low hundreds-of-thousands of vectors). `@mosaicstack/memory` defines a `VectorStore` interface with pgvector as the default adapter. The interface boundary makes Qdrant a drop-in migration if PG resource contention or scale demands it later. Zero additional infrastructure for v0.1.0. Rationale: Reduces ops burden; pgvector HNSW indexes are fast at this scale; interface abstraction costs almost nothing now.

+## Pi Goal Loop Operations
+
+The reviewed runtime asset is deployed at
+`~/.config/mosaic/runtime/pi/goal-extension.ts` by framework install/update. Do not install another
+copy under `~/.pi/agent/extensions/`; duplicate registration can create suffixed commands and two
+competing lifecycle controllers.
+
+Operational checks:
+
+1. Run `mosaic pi` and verify `/goal help` is available.
+2. Use `/goal status` to inspect phase, turn/no-progress limits, compaction checks, and evidence.
+   Reports persist in Pi session data; controller-owned state redacts common credential shapes, but
+   Pi's model/tool-call history is separate. Operators must not place secrets or raw sensitive output
+   in goals, pause reasons, or evidence.
+3. Use `/goal pause <reason>` before planned maintenance or manual investigation. Pause and cancel
+   abort the current goal-driven run when Pi is busy.
+4. Use `/goal resume` only after addressing a blocker; counters restart with the configured bounds.
+5. Use `/goal cancel` before replacing an unfinished goal.
+
+A blocked or exhausted goal remains stopped and visible; Mosaic does not automatically raise its
+limits or restart the process. Framework sync owns file deployment, while Pi's native session file
+owns branch replay. Process/host restart remains the responsibility of the existing runtime or fleet
+supervisor.

+## Pi Persistent Goals
+
+`mosaic pi` loads a Mosaic-owned goal extension from
+`~/.config/mosaic/runtime/pi/goal-extension.ts`. It is deliberately not installed in
+`~/.pi/agent/extensions/`; framework installation and updates manage it with the rest of the Mosaic
+runtime assets.
+
+Start Pi, then set a goal:
+
+```text
+/goal set Deliver the feature, tests, documentation, and verification evidence
+# Shorthand:
+/goal Deliver the feature, tests, documentation, and verification evidence
+```
+
+Control and inspect the loop with:
+
+| Command                | Behavior                                                           |
+| ---------------------- | ------------------------------------------------------------------ |
+| `/goal status`         | Show phase, limits, compaction checks, latest report, and evidence |
+| `/goal pause [reason]` | Stop autonomous continuation while preserving the goal             |
+| `/goal resume`         | Resume with fresh turn and no-progress counters                    |
+| `/goal cancel`         | Cancel the goal and remove its active status                       |
+| `/goal help`           | Show command help                                                  |
+
+While a goal is active, Mosaic injects its contract before every Pi model request and checks every
+completed model/tool turn. The agent ends each work cycle with the structured
+`mosaic_goal_report` tool. `achieved` is provisional until a second consecutive report rechecks the
+whole goal with evidence. A continuation report or a successful compaction resets provisional
+verification.
+
+Goal statements and reports are stored in Pi session data. Mosaic redacts common credential shapes
+before appending its goal-state entries and before goal tool output or `/goal status`, but
+pattern-based redaction is not a secret store. Pi's own model-message and tool-call records are
+outside that redactor. Never put tokens, passwords, private keys, connection strings, or raw
+sensitive output in a goal or report; cite the command, artifact, and pass/fail result instead.
+
+The loop stops instead of running forever when it is paused, blocked, cancelled, verified, reaches
+its turn limit, or repeats the same no-progress report too many times. Defaults are 40 turns and 6
+repeated no-progress reports. Operators may lower or raise them within enforced bounds before
+launching Pi:
+
+```bash
+MOSAIC_GOAL_MAX_TURNS=60 MOSAIC_GOAL_MAX_NO_PROGRESS=8 mosaic pi
+```
+
+Goal state is branch-specific Pi session data. It survives compaction and session resume, but Pi's
+process still must be relaunched or supervised after a process/host failure. This initial verifier
+checks structured evidence twice; it cannot mathematically prove every arbitrary natural-language
+goal. Use explicit acceptance criteria and inspect `/goal status` for consequential work.

@@ -396,6 +397,85 @@ M1 intentionally manages Claude Code only. Pi's Mosaic launcher can discover the
 canonical root directly. Codex still relies on the existing full skill-sync
 linker and needs separate parity analysis before this lifecycle API is extended.
 
+## Pi Persistent Goal Extension
+
+The source of the Mosaic-owned Pi goal controller is:
+
+```text
+packages/mosaic/framework/runtime/pi/goal-extension.ts
+```
+
+The framework manifest classifies `runtime/**` as framework-owned. Both the bash installer and the
+TypeScript file adapter therefore deploy the same reviewed source to:
+
+```text
+$MOSAIC_HOME/runtime/pi/goal-extension.ts
+# default: ~/.config/mosaic/runtime/pi/goal-extension.ts
+```
+
+Do not copy or link this extension into `~/.pi/agent/extensions/`. The launcher function
+`discoverPiExtensionArgs()` emits the core `mosaic-extension.ts` first and the optional
+`goal-extension.ts` second, preserving compatibility with an older installed framework that does
+not have the goal file yet.
+
+### Lifecycle design
+
+| Pi API                         | Goal-controller responsibility                                                    |
+| ------------------------------ | --------------------------------------------------------------------------------- |
+| `registerCommand('goal')`      | Set, inspect, pause, resume, or cancel one branch-specific goal                   |
+| `registerTool(...)`            | Record a terminating structured progress report with evidence                     |
+| `context`                      | Inject the active goal contract before every provider request                     |
+| `turn_end`                     | Record every turn, reject mixed final reports, and enforce the turn bound         |
+| `agent_settled`                | Start one deduplicated continuation only after Pi has no retry/compact/queue work |
+| `session_compact`              | Record the compact check, reset provisional verification, and defer idle work     |
+| `session_start`/`session_tree` | Rebuild state from custom entries on the active branch                            |
+| `session_shutdown`             | Invalidate deferred callbacks and clear UI state                                  |
+
+State is appended as `mosaic-goal-state` custom entries, which do not enter model context. The
+`context` hook creates a fresh hidden `mosaic-goal-context` message for each request instead of
+trusting compaction summaries. The `mosaic_goal_report` result uses `terminate: true`; when it is the
+sole final tool call, Pi avoids an unnecessary model response before the controller decides whether
+to verify, continue, or stop.
+
+Before state is appended or displayed, the controller applies bounded credential-pattern redaction
+to the goal statement, report summary/evidence/next step, and stop reason. Fingerprints are computed
+over redacted report content. Pi session entries are append-only, so a credential-bearing legacy
+entry cannot honestly be erased by the extension: restoration fails closed, emits a warning, and
+requires removal of the affected session before setting a new goal. This is defense-in-depth rather
+than a secret-storage contract, and it does not rewrite Pi's separate model-message/tool-call
+history. Goal prompts tell the agent not to submit credentials or raw sensitive output, and tests use
+canaries to prove known forms do not reach new custom entries, status text, context, or tool details
+while ordinary typed fields such as `token: string` remain intact.
+
+Completion remains evidence-gated but semantic: two consecutive `achieved` reports are required,
+and the second run is explicitly a verification pass. This avoids an extra judge-model request after
+every turn. Deterministic validator commands are intentionally not accepted as `/goal` input in this
+slice, so never describe this mechanism as proof of arbitrary natural-language completion.
+
+### Tests and local smoke workflow
+
+```bash
+pnpm --filter @mosaicstack/mosaic exec vitest run \
+  src/runtime/pi-goal-extension.spec.ts \
+  src/commands/launch.spec.ts \
+  src/config/file-adapter.test.ts
+
+bash packages/mosaic/framework/tools/quality/scripts/test-install-migration.sh
+```
+
+For an additive local smoke test without reseeding unrelated live framework files:
+
+```bash
+install -D -m 0644 \
+  packages/mosaic/framework/runtime/pi/goal-extension.ts \
+  ~/.config/mosaic/runtime/pi/goal-extension.ts
+
+pi --extension ~/.config/mosaic/runtime/pi/goal-extension.ts
+```
+
+Use `/goal help`, `/goal set ...`, and `/goal status` in that test session. A released framework
+sync installs the file, and a released Mosaic CLI loads it automatically through `mosaic pi`.

+# #1043 — Fleet pane git-identity propagation
+
+## Objective
+
+Ensure a fleet seat's launched runtime process receives its roster-derived `MOSAIC_GIT_IDENTITY`, and lock the complete generated-environment propagation boundary with an enumerated set comparison.
+
+## Tracking
+
+- External issue: `mosaicstack/stack#1043`
+- Branch: `fix/1043-pane-git-identity`
+- Coordinator: `tl-mosaic`
+- `docs/TASKS.md`: read-only by project worker contract; not modified.
+
+## Constraints
+
+- RED-first bug reproducer is mandatory.
+- R7 delete-the-subject mutation must turn the behavioral test red.
+- Assert launched-process environment, not source text.
+- One push only; do not poll CI after push.
+- Run the CI queue guard immediately before push and report its `state=` line as state, not evidence.
+- Do not modify a live host launcher or obtain/copy another credential.
+- Self-post the PR, verify provider attribution, then stop.
+- Final status wording: `believed-fixed, pending jarvis validation`.
+
+## Scope inventory
+
+Re-derived against `origin/main` at `85d2108e`:
+
+- Launch consumer: `packages/mosaic/framework/tools/fleet/start-agent-session.sh`
+- Behavioral launch test: `packages/mosaic/framework/tools/fleet/test-start-agent-session.sh`
+- Generated-environment contract/parser: `packages/mosaic/src/fleet/generated-env-boundary.ts`
+- Roster projection producers:
+  - `packages/mosaic/src/commands/fleet.ts`
+  - `packages/mosaic/src/fleet/fleet-reconciler.ts`
+  - `packages/mosaic/src/fleet/fleet-agent-crud.ts`
+  - `packages/mosaic/src/fleet/v1-v2-migration.ts`
+- Contract and producer tests discovered by repository search.
+- Generated-environment operator/developer docs and their executable documentation contract test.
+
+Discrepancy sent to `tl-mosaic`: current main no longer contains the charter's `PANE_SHELL_SNIPPET`; #772 replaced it with an `/usr/bin/env -i` argv launch boundary, and current generated projections do not declare git identity. Code-read inventory is **NOT MEASURED** behavior.
+
+## Plan
+
+1. Add the process-environment set-comparison regression first and record RED.
+2. Add roster-derived `MOSAIC_GIT_IDENTITY=<agent name>` to the complete generated projection contract.
+3. Validate identity syntax and equality with `MOSAIC_AGENT_NAME`; pass it through the clean pane environment.
+4. Update affected projection tests and generated-environment docs.
+5. Run focused and baseline gates.
+6. Perform R7 by deleting the pane propagation entry, prove RED, restore, and prove GREEN.
+7. Run independent review, remediate, commit, queue guard, one push, self-post PR, verify provider attribution, and stop without CI polling.
+
+## Budget
+
+No explicit token cap was provided. Working cap: one narrow logical unit, no dependency installation unless existing tooling requires it, no unrelated refactor.
+
+## Evidence log
+
+### TDD and mutation evidence
+
+- RED-first, repository launcher: `bash packages/mosaic/framework/tools/fleet/test-start-agent-session.sh` exited 64 on pre-fix source with `code=unknown-key key=MOSAIC_GIT_IDENTITY`. The generated seat could not launch with the required declared identity.
+- GREEN: the same repository launcher test emitted `ok - start-agent-session generated environment boundary`.
+- R7 delete-the-subject: removed only `"MOSAIC_GIT_IDENTITY=$MOSAIC_GIT_IDENTITY"` from the repository launch array; the same test exited 1 with `FAIL: runtime pane omitted or changed generated environment keys: MOSAIC_GIT_IDENTITY`.
+- R7 restoration: restored that launch entry; the same test returned green.
+- Launcher under test is explicitly `packages/mosaic/framework/tools/fleet/start-agent-session.sh` through the test's `$START`, **not** the stale installed host copy.
+
+### Situational and focused tests
+
+- Repository launcher boundary: green, including set comparison of all nine generated projection entries and fail-before-tmux cases for missing, unsafe, mismatched, and local-shadow Git identity.
+- Fleet systemd launcher integration: `bash packages/mosaic/framework/systemd/user/test-fleet-units.sh` — green.
+- Focused Mosaic Vitest set: 6 files, 311 tests — green.
+- `bash -n` on changed shell files — green.
+- `git diff --check` — green.
+
+### Baseline gates
+
+- `pnpm typecheck` — 45/45 tasks green.
+- `pnpm lint` — 25/25 tasks green.
+- `pnpm format:check` — green.
+- `pnpm test:checkout` — green.
+- Repository-wide Vitest under a hermetic current-version npm prefix: Mosaic 81/81 files and 1510/1510 tests green; other workspace test tasks shown green before the framework-shell phase.
+- Canonical `pnpm test` is not fully green on this host for unrelated environment-sensitive gates:
+  1. the first two runs exposed the globally installed Mosaic 0.0.48 update banner in three CLI smoke tests expecting empty stderr;
+  2. after isolating that global-version input, the framework wake assertion aborted at the known `#973` Bash `BASH_LINENO` convention check (exit 97; observed `[3 5]`, expected `[3 4]`).
+  No tests were weakened or bypassed; focused changed-surface tests are green. CI remains the canonical clean-environment result and is intentionally not polled after push per charter.
+
+### Independent review
+
+- Codex code review first pass: request changes for missing shell rejection-path coverage.
+- Remediation: added table-driven missing/unsafe/mismatch/local-shadow launcher cases, each asserting no tmux call.
+- Codex code re-review: **approve**, no findings, confidence 0.88.
+- Codex security review: risk `none`, no findings, confidence 0.97.
+
+### Acceptance criteria mapping
+
+| Acceptance criterion | Evidence |
+| --- | --- |
+| AC-FGI-01: launched process receives every generated key/value | Repository launcher process-environment `comm -23` set comparison; GREEN and R7 RED evidence above |
+| AC-FGI-02: missing, unsafe, or split identity fails before tmux | Table-driven shell cases plus TypeScript generated-boundary tests |
+| AC-FGI-03: focused/baseline/review evidence recorded | Commands and review outcomes above; host-sensitive full-suite limitations stated explicitly |
+
+### Documentation checklist
+
+- PRD updated with #1043 requirements and acceptance criteria.
+- Fleet launch runbook, generated-env concept, and generated-env reference updated.
+- No API/OpenAPI, sitemap, user publishing target, deployment, or external docs publication change applies.
+- `docs/TASKS.md` remains unmodified per its single-writer project contract.
+
+## Round 2 — PR #1073 review 97 remediation
+
+### Review blocker
+
+The launched-process suite was signed-excluded from CI enumeration. Manual GREEN/R7 evidence therefore did not prove a PR workflow could detect regression.
+
+### RED-first and canonical wiring
+
+1. Removed the suite's signed exclusion before adding a CI execution path.
+2. `check-test-enumeration.sh` went RED with exact `UNENUMERATED` output for `test-start-agent-session.sh`: population 49, enumerated 30, excluded 18.
+3. Added both `framework/tools/fleet/test-start-agent-session.sh` and `framework/systemd/user/test-fleet-units.sh` to `@mosaicstack/mosaic`'s canonical `test:framework-shell` chain.
+4. The guard returned GREEN: population 49, enumerated 32, excluded 18, surfaces 45. The systemd suite is outside the guard's tools-only population but now has the same explicit canonical execution disposition.
+
+### Workflow-level R7
+
+- Deleted only the pane launch entry `"MOSAIC_GIT_IDENTITY=$MOSAIC_GIT_IDENTITY"`.
+- Ran the exact `.woodpecker/ci.yml` test-step command, `pnpm test`, with only a temporary PATH-scoped npm shim reporting the checkout's current 0.0.49 version so the unrelated global 0.0.48 banner could not preempt the shell chain.
+- Result: exit 1 at `@mosaicstack/mosaic#test`, with the enumeration guard GREEN followed by `FAIL: runtime pane omitted or changed generated environment keys: MOSAIC_GIT_IDENTITY`.
+- Restored the launch entry. The canonical `test:framework-shell` chain then reached both newly wired suites and printed both GREEN markers before the known unrelated #973 host-only `BASH_LINENO` abort.
+- An actual provider PR workflow on the intentionally broken mutant is **NOT MEASURED**: the one-push constraint forbids pushing a red mutant and then a repaired head. Local execution proves the exact PR workflow command and dependency chain go RED on the subject deletion; CI on the repaired pushed head remains canonical.
+
+### Workflow population
+
+- **DEFINED:** 3 workflows (`ci.yml`, `ci-image.yml`, `publish.yml`).
+- **ELIGIBLE for `pull_request`:** 1/3 (`ci.yml`), based on top-level `when:` clauses.
+- **REPORTED:** Round-1 exact-head provider read reported 1/1 eligible context (`ci/woodpecker/pr/ci`). Post-remediation-head reported count is **NOT MEASURED** by this seat because CI polling is prohibited; workflow definitions and eligibility did not change.
+
+### Independent remediation review
+
+- First Round-2 review identified a CI-image blocker: the newly wired launcher suite used Perl, which the Alpine CI base does not install.
+- Replaced the suite's three Perl-only fixture mutations with POSIX/BusyBox-compatible `sed -i` substitutions; production behavior and assertions are unchanged.
+- Codex re-review: **APPROVE**, confidence 0.93, no findings.
+
+### Vitest denominator reconciliation
+
+The PR's `311/311` is correct for its explicitly named six-file command at both the original and remediation worktrees:
+
+- generated environment boundary: 24
+- fleet documentation: 23
+- Tess service profile: 6
+- fleet regen command: 27
+- fleet agent CRUD command: 22
+- fleet command: 209
+- total: **311**
+
+Review 97 reported 312/312 without naming its six files. That is a different or miscounted population and cannot replace the command-scoped 311 denominator; the PR follow-up will name the exact files and arithmetic.
+
+## Round 3 — Alpine stale-marker portability
+
+### Objective and plan
+
+- Replace the GNU-only relative-date fixture with a deterministic POSIX/BusyBox timestamp while preserving the required stale-marker assertion.
+- Re-run the launcher suite in the canonical `ci-base:latest` Alpine image, then run applicable repository gates and independent review.
+- Update the PR body to name the repeated GNU-host/Alpine-CI portability pattern, run the mandatory queue guard, push once, verify provider attribution, and stop without CI polling.
+- Working budget: 8K tokens; scope is one fixture line plus delivery evidence. No production behavior changes.
+
+### RED-first evidence
+
+Before the fix, the canonical CI image command
+`docker run --rm -v "$PWD:/work" -w /work git.mosaicstack.dev/mosaicstack/stack/ci-base:latest bash packages/mosaic/framework/tools/fleet/test-start-agent-session.sh`
+exited 1 at the stale-marker setup with exact BusyBox output
+`touch: invalid date '10 seconds ago'`. The prior fresh-marker assertions had already executed, matching pipeline 2233's failure location.
+
+### Root cause and fix
+
+The test used GNU `touch -d` relative-date parsing although the PR workflow runs on Alpine/BusyBox. The fixture now uses POSIX `touch -t 200001010000.00`, a fixed timestamp that is unconditionally stale; the stale assertion remains mandatory and was not made tolerant of missing timestamp metadata.
+
+### Structural pattern
+
+This is the third GNU-host/Alpine-CI portability defect in the lane: GNU `grep` multi-match counting, Perl-only fixture mutation, and GNU `touch -d` date parsing. The repeated cause is shell suites authored on a GNU host but executed in an Alpine CI image; durable prevention belongs in CI-image execution or portability lint, not assertion weakening.
+
+### GREEN and quality evidence
+
+- Focused launcher suite in `ci-base:latest`: exit 0, `ok - start-agent-session generated environment boundary`.
+- Canonical test step in `ci-base:latest` with the pipeline's `pgvector/pgvector:pg17` service, readiness check, migration, and `pnpm test`: exit 0; 46/46 Turbo tasks; Mosaic 81/81 files and 1510/1510 tests; Gateway 57 passed/5 skipped files and 629 passed/11 skipped tests; enumeration 49 population / 32 enumerated / 18 signed exclusions / 45 named surfaces.
+- The first image-only `pnpm test` attempt lacked the pipeline PostgreSQL service and failed only on connection refusal after the launcher suite was GREEN. The rerun supplied the canonical service precondition and passed.
+- Canonical-image baseline: typecheck 45/45 tasks, lint 25/25 tasks, format check GREEN; `git diff --check` GREEN.
+- Independent Codex code review: APPROVE, confidence 0.96, 2/2 Round-3 files, no findings.
+- Independent Codex security review: risk none, confidence 0.99, 2/2 Round-3 files, no findings.
+
+### Re-derived inventory and denominators
+
+- Round-3 git delta: **2/2 files** — launcher suite and task scratchpad; 25 insertions / 1 deletion before evidence finalization.
+- Full PR path inventory against `origin/main` at `85d2108e`: **19/19 changed paths**; Round 3 adds no new PR path.
+- Workflow definition population: **1/3 pull-request-eligible** (`ci.yml` of `ci.yml`, `ci-image.yml`, `publish.yml`).
+- Do not re-litigate the settled 311/312 populations; both are valid for their separately named Tess6 and CRUD-core7 sets.
+
+## Round 4 — bound stale-marker observation
+
+### Objective and plan
+
+- Make the heartbeat assertion discriminate an initially stale native marker from a fresh marker without changing the production staleness threshold or shortening the polling window.
+- Freeze only the sidecar's numeric observation clock during the stale-fixture arm so elapsed assertion time cannot turn a fresh mutant stale.
+- Prove two independent mutants RED: disable production stale-marker detection while retaining the stale fixture; replace the stale fixture with a fresh marker. Restore the tree and prove GREEN in the canonical Alpine image.
+- Re-derive the changed-path inventory, run applicable quality and independent review gates, commit with environment-only author/committer identity, queue-guard, push once, verify provider attribution using curl stdin config, and stop without CI polling.
+- Working budget: 8K tokens. Scope is the launcher test and its scratchpad evidence; production launcher behavior remains unchanged.
+
+### Root cause and bounded observation
+
+The 30 × 0.1-second assertion window overlaps the production `now - marker > interval * 2 + 1` threshold at interval 1. Depending on second boundaries and load, a fresh marker can age past the threshold before the assertion ends. A focused pre-fix fresh-mutant attempt returned RED while Review 101's full-suite run returned GREEN; the differing result is itself timing dependence, not a discriminating assertion.
+
+The test now supplies a fixed numeric epoch only to the stale-fixture sidecar. Its real marker mtime is still read from the filesystem, but assertion runtime cannot advance `now`. Date formatting still delegates to the image's real `/bin/date`. Neither the production threshold nor the 30 × 0.1-second polling window changed.
+
+### Two-mutant RED / restored GREEN
+
+All three runs used `git.mosaicstack.dev/mosaicstack/stack/ci-base:latest`:
+
+1. **Stale-detection mutant RED:** replaced only the production stale-age predicate with `false` while retaining the fixed stale marker; suite exit 1 with `FAIL: heartbeat sidecar did not resume after native marker became stale or absent`.
+2. **Fresh-marker mutant RED:** replaced only `touch -t 200001010000.00` with fresh `touch`; suite exit 1 with the same failed stale-resumption assertion. The fixed observation epoch kept the mutant fresh throughout all 30 polls.
+3. **Restored tree GREEN:** suite exit 0 with `ok - start-agent-session generated environment boundary`.
+
+### Re-derived inventory
+
+- Round-4 delta: **2/2 files** — launcher test plus task scratchpad; production launcher delta is empty.
+- Full PR inventory against `origin/main`: **19/19 paths**; Round 4 adds no path.
+- Production stale threshold remains `now - marker > iv * 2 + 1`; assertion polling remains 30 × 0.1 seconds.
+- Review 101's confirmed enumeration/workflow/CI and attribution evidence is accepted without re-polling or re-derivation.
+
+## Residual risk
+
+- Landing on `main` does not update the currently installed host launcher. Host framework installation/reseed and Jarvis live-seat validation are separate downstream events.
+- Canonical CI result is pending and will not be polled by this seat.

+# #1098 — Framework shell portability / red main
+
+## Objective
+
+Restore terminal-green `main` by making the `test-start-agent-session.sh` clean-environment assertion semantic and portable without removing either newly enumerated framework-shell suite.
+
+## Scope
+
+- Tracking issue: `mosaicstack/stack#1098`
+- Branch: `fix/framework-shell-portability`
+- Base: `origin/main` at `4fa2768962702d53e16e8b67ee6ad52ebcb0910e`
+- Primary file: `packages/mosaic/framework/tools/fleet/test-start-agent-session.sh`
+- Requirements source: `docs/PRD.md` § Framework shell assertion portability (#1098)
+- Out of scope: deployed files under `~/.config/mosaic`, pnpm-store cleanup, checkout deletion, and changes to the launcher’s `/usr/bin/env -i` behavior.
+
+## Acceptance criteria
+
+1. The test inspects the captured NUL-delimited tmux argv semantically and accepts an adjacent `/usr/bin/env`, `-i` pair regardless of trailing payload size or pipe scheduling.
+2. Missing `/usr/bin/env`, missing `-i`, and non-adjacent `-i` remain failures.
+3. Failure output includes the observed argv records with stable indexes and shell escaping; it exposes no credentials because this fixture supplies only generated non-secret launch data.
+4. The focused suite passes on the dev host and in the repository CI image; the blocking PR/main pipeline returns terminal green.
+5. Independent review passes; PR is squash-merged and #1098 is closed only after merged-main CI is terminal green.
+
+## Budget
+
+- ASSUMPTION: 30K-token working budget; rationale: one shell-test defect plus full PR/CI lifecycle.
+- Auto-reduction: focused shell and package gates first; rely on canonical Woodpecker for the full monorepo suite rather than duplicating a dependency install under constrained `/home`.
+- Disk baseline before clone/build: `/home` 7.1G free (99% used), `/tmp` 2.4G free (92% used).
+
+## Investigation
+
+### First-hand CI evidence
+
+- Public log: `GET https://ci.mosaicstack.dev/api/repos/47/logs/2269/53041`
+- Decoded 1,436 entries (11 null `data` entries treated as empty log rows), 190,756 bytes.
+- Failure: `FAIL: pane command did not clear its environment` immediately after the expected pane-PID warning.
+- BusyBox primitives, complete assertion pipeline, real CI image, stale/current image digests, Turbo cache masking, gateway failure, and heartbeat-sidecar concurrent writing were independently excluded.
+
+### Root cause
+
+The assertion ends in:
+
+```bash
+printf '%s\n' "$pane_args" | tail -n +"$after_pane_env" | grep -qxF -- '-i'
+```
+
+The script has `set -o pipefail`. `grep -q` exits as soon as it finds the valid `-i` record. Upstream `tail`/`printf` can then receive SIGPIPE, making the aggregate pipeline nonzero even though grep returned 0 and the semantic property is true. This depends on payload size, pipe capacity, and scheduling, explaining a local/image pass with a CI failure.
+
+Discriminating stress control with `/usr/bin/env` followed immediately by `-i`:
+
+- 8,192-byte trailing payload: `printf=0 tail=0 grep=0`, aggregate 0.
+- 16,384-byte trailing payload: `printf=0 tail=141 grep=0`, aggregate 141.
+- 32,768+ bytes: `printf=141 tail=141 grep=0`, aggregate 141.
+- A full-reading `grep -xF` control remained 0 for every payload.
+
+This is a third branch omitted by the earlier present-vs-corrupted split: the pair can be present and intact while `pipefail` reports an upstream SIGPIPE.
+
+## TDD plan
+
+1. RED: preserve the one-off stress reproducer above and add an automated large-argv semantic regression that fails under the current pipeline implementation.
+2. GREEN: parse the authoritative NUL-delimited capture into a Bash array and search for an adjacent `/usr/bin/env`, `-i` pair without a short-circuit pipeline.
+3. Add negative controls for missing, detached, and reversed tokens.
+4. On failure, print indexed `%q` argv records before returning nonzero.
+5. Run focused suite, mutation controls, shell syntax/format checks, then repository baseline gates feasible without dependency installation.
+6. Independent review, queue guard, push, PR, CI, coordinator merge authorization, squash merge, merged-main CI, issue close.
+
+## Progress
+
+- [x] Checkout created and based on `origin/main` `4fa27689`.
+- [x] CI log decoded directly.
+- [x] Root-cause stress control reproduced semantic match + aggregate pipeline failure.
+- [x] RED evidence: intact `/usr/bin/env`, `-i` fixture produced component statuses `0/141/0` and aggregate 141 under the former `grep -q` pipeline; full-reading semantic control stayed 0.
+- [x] GREEN implementation: direct NUL-argv adjacency parser, indexed diagnostics, and full-reading scalar predicates replace all load-bearing early-exit pipelines in this test.
+- [x] Baseline/situational tests:
+  - focused launcher suite: PASS on GNU host and cached Alpine CI image;
+  - paired `test-fleet-units.sh`: PASS;
+  - enumeration guard: PASS (`population=53`, `enumerated=36`, `excluded=18`), 14/14 mutation needles;
+  - `bash -n`, ShellCheck, `git diff --check`: PASS;
+  - static denominator after change: zero load-bearing `grep -q`/`head`/`-m1` pipeline candidates in `test-start-agent-session.sh`;
+  - delete-the-subject mutation removing production `-i`: RED with 78 indexed argv records, byte count, and explicit boundary failure.
+- [x] Independent review:
+  - first Codex review: request changes — negative fixtures did not each assert diagnostics;
+  - remediation: centralized predicate + diagnostic wrapper and exercised all four negative fixtures;
+  - second Codex review: APPROVE, 0 blockers/should-fix/suggestions;
+  - Codex security review: risk none, 0 findings.
+- [ ] PR CI, formal fleet review, merge, merged-main CI, issue closure.
+
+## Documentation disposition
+
+- Updated canonical `docs/PRD.md` with FSP requirements and acceptance criteria.
+- This is an internal test/reliability change with no API, user workflow, deployment, navigation, or publishing-surface change; no user/admin/API/sitemap update is required.
+- `docs/TASKS.md` remains unchanged because the project contract makes it orchestrator-only.
+
+## Risks
+
+- The CI failure did not print its captured argv, so the exact CI payload is unavailable. The stress control proves the assertion is non-portable and can emit the exact false verdict; branch CI is the canonical confirmation that replacing it resolves pipeline 2269’s failure class.
+- Printing fixture argv is safe only while this test’s projection remains non-secret. The diagnostic must stay scoped to the test capture and shell-escaped.

+# #1099 — pipefail + early-exit sweep
+
+## Scope and decisions
+
+- Baseline `df4c591ab42aa1ae62c12935fdc0e772684864a0`, after #1100 removed its 35 sites.
+- Split into review-sized non-closing tranches: runtime/general; tmux/git/quality tests; wake validation/tests.
+- Do not equate class membership with demonstrated risk. Do not use payload size or pipeline stage count as a safety proxy.
+- Preserve the issue's withdrawn findings for `qa-hook-stdin.sh` and the two fresh-directory `pnpm pack` lookups. Fix `install.sh:312` because malformed multi-root input must reach its named handler.
+
+## Tranche 1 TDD
+
+RED-first control: `node --test scripts/pipefail-early-exit.test.mjs` reported exactly 26 non-accepted runtime/general sites, including `install.sh:312`, and exited 1. A checked-in fixture generated from immutable baseline `df4c591a` records all 26 normalized sites; the control passes every fixture entry through the same scanner, asserts exact identity/count/uniqueness, and separately requires zero findings in the current tree. It also inventories accepted sites rather than silently excluding whole files.
+
+Construction choices:
+
+- here-string/file redirection for scalar grep assertions;
+- full capture then parameter expansion for first-line selection;
+- arrays/`mapfile` for complete populations;
+- direct jq/awk/grep selection where one tool can express the property;
+- no `|| true` added to a load-bearing assertion.
+
+Site-by-site verdicts: `docs/reports/quality/1099-pipefail-sweep.md`.
+
+## Tranche 2 TDD
+
+Expanded the unconditional scanner over 11 non-wake test harnesses. RED named exactly 22 source lines; a second immutable-baseline fixture now asserts those 22 entries through the same scanner. Rewrites preserve command status by capturing producers before redirected assertions, use parameter expansion for line selection, and use complete `mapfile` populations where ordering matters. Current-tree finding count is zero for tranches 1 and 2.
+
+## Tranche 3 TDD
+
+Expanded the shared scanner over four wake validation harnesses. RED named 26 occurrences. The wake fixture asserts 26 occurrences / 25 normalized identities through the same scanner; all scalar assertions now use redirection, direct jq selection, complete capture, or consuming diagnostic ranges. Current-tree finding count is zero across the full scoped population.
+
+## Verification so far
+
+- `bash -n` on every changed shell script: pass.
+- structural Node control: pass.
+- `test-mutate-push-guard.sh`: 8/8 pass.
+- `test-send-message-verdict.sh`: 3/3 pass.
+- `test-send-message-socket.sh`: pass.
+- Independent review 143 found two semantic regressions: a help-probe `|| true` changed the failure truth table, and an unguarded Git capture changed non-Git data-dir behavior from rc 0 + JSON to silent rc 128. Both received RED-first regressions before correction; help status is now separate and required, and Git status remains condition-guarded.
+- Wake static inventory remains aligned at 261/261 after line-neutral rewrites; no static-set mismatch. Wake detector/reconcile/digest/preimage suites terminate at their existing fail-closed #973 `BASH_LINENO` environment probe (exit 97, observed `[3 5]`, expected `[3 4]`) before subject tests. No bypass or skip was used; canonical CI remains required.
+- ShellCheck reports only pre-existing source-following, unused-variable, and untouched `ls | head` findings; no new diagnostic was introduced.

+# #1150 — Pi persistent goal extension
+
+- **Task ID:** ISSUE-1150 (no `docs/TASKS.md` row; that file is orchestrator-only)
+- **Issue:** #1150 — `pi: add persistent /goal controller extension to Mosaic framework`
+- **Branch:** `feat/1150-pi-goal-extension`
+- **Mode:** Delivery
+- **Status:** in progress
+
+## Objective
+
+Build and locally validate a Mosaic-owned Pi `/goal` extension. Source must ship from
+`packages/mosaic/framework/runtime/pi/`, framework sync must deploy it under
+`~/.config/mosaic/runtime/pi/`, and no extension/configuration asset may be written into `~/.pi`.
+Pi's native session manager remains the owner of session entries.
+
+## Scope and acceptance source
+
+- Canonical requirements: `docs/PRD.md`, section **Pi Persistent Goal Loop (#1150)**.
+- User intent: continuous goal orientation and status checking after each Pi turn and compaction,
+  tested locally before framework delivery.
+- Documentation target: canonical in-repo user/developer/runtime docs; no external publication.
+
+## Assumptions
+
+- `ASSUMPTION:` Initial semantic verification uses two consecutive structured, evidence-bearing
+  reports from the working agent rather than a second model request after every turn. This keeps the
+  loop testable and avoids doubling model cost while making the limitation explicit.
+- `ASSUMPTION:` Default autonomous bounds are 40 turns and 6 repeated no-progress reports, with only
+  bounded numeric environment overrides.
+- `ASSUMPTION:` A local smoke copy to `~/.config/mosaic/runtime/pi/goal-extension.ts` is authorized by
+  the user's explicit request. Full framework reseed into the live home is not required for the smoke
+  test and would touch unrelated framework-owned files.
+
+## Budget
+
+- Working estimate: 30K implementation/review tokens.
+- Hard user cap: none stated.
+- Cost control: deterministic fake-Pi tests; no nested evaluator calls; only bounded arithmetic/load
+  smoke workflows against the installed runtime.
+
+## Plan
+
+1. Update PRD and create tracking/scratchpad artifacts.
+2. Read launcher, installer ownership, Pi extension, and documentation surfaces.
+3. TDD: add fake-Pi behavior tests for commands, state restoration, turn checks, compaction, limits,
+   verification, and continuation deduplication.
+4. Implement `runtime/pi/goal-extension.ts` and deterministic launcher discovery.
+5. Add framework-sync/deployment acceptance coverage.
+6. Update user, developer, runtime, framework README, and sitemap documentation.
+7. Run focused tests, local Mosaic-path smoke test, then baseline repository gates.
+8. Run independent review, remediate, commit, push/PR/CI/merge/issue closure per delivery gates.
+
+## TDD decision
+
+Applied. The continuation state machine and lifecycle scheduling are control-path logic where a race
+or false terminal state can cause unbounded work or premature completion.
+
+## Progress checkpoints
+
+- [x] Issue #1150 created through Mosaic wrapper.
+- [x] Isolated worktree created from `origin/main`.
+- [x] PRD requirements and acceptance criteria added.
+- [x] Task scratchpad created.
+- [x] RED controller and security-regression tests written and observed failing before implementation.
+- [x] Goal controller, launcher discovery, framework deployment coverage, and bounded state machine
+      implemented.
+- [x] User, admin, developer, runtime, adapter, README, and sitemap documentation updated.
+- [x] Final source copied additively to `~/.config/mosaic/runtime/pi/goal-extension.ts`; source and
+      deployed SHA-256 are identical.
+- [x] Live Pi RPC smoke from the exact Mosaic path reached `achieved` with two verification passes and
+      no extension errors.
+- [x] Baseline and situational checks completed, except the explicitly documented unavailable
+      PostgreSQL-only root integration case.
+- [x] Independent code and OWASP/security reviews completed; all findings remediated and re-reviewed.
+- [ ] Commit, push, PR, terminal-green CI, squash merge, and issue closure complete.
+
+## Tests and evidence
+
+### Situational
+
+- `pnpm --filter @mosaicstack/mosaic exec vitest run src/runtime/pi-goal-extension.spec.ts`
+  - final: 25 passed.
+  - Covers commands, per-turn checks, context injection, two-pass verification, mixed-report
+    rejection, bounded limits, compaction, branch restore, stale timers, credential redaction,
+    typed-field false-positive protection, and append-only legacy-state fail-closed behavior.
+- Final focused launcher/controller/file-adapter run: 3 files / 67 tests passed.
+- Final V8 coverage for `framework/runtime/pi/goal-extension.ts`:
+  - 99.17% statements/lines, 93.78% branches, 100% functions.
+- Installer migration fixture: 24 passed and byte-compared the deployed framework asset.
+- Standalone extension TypeScript check against installed Pi 0.84.1 types passed:
+  `pnpm --filter @mosaicstack/mosaic exec tsc --noEmit --pretty false --module NodeNext
+  --moduleResolution NodeNext --target ES2022 --skipLibCheck framework/runtime/pi/goal-extension.ts`.
+- Live deployment/load evidence:
+  - source/deployed SHA-256:
+    `1f0a3806e0948ad5f49684273a7e535e9880c148f7fd16d13ee487fcd601f637`.
+  - `get_commands` identified `/goal` as an extension command sourced from
+    `~/.config/mosaic/runtime/pi/goal-extension.ts`; `/goal help` succeeded; zero extension errors.
+  - live arithmetic goal ended `achieved`, verification `2/2`, with 3 goal reports / 3 agent starts
+    and zero extension errors.
+  - no goal extension exists under `~/.pi` extension paths.
+
+### Baseline
+
+- `pnpm build`: passed before the final framework-only redaction remediation; the extension is not a
+  package build input and its final source passed the standalone Pi type check.
+- `pnpm typecheck`: 45/45 tasks passed.
+- `pnpm lint`: 25/25 tasks passed.
+- `pnpm format:check`: passed.
+- Final Mosaic package components:
+  - Vitest: 82 files / 1,539 tests passed.
+  - full `test:framework-shell` harness passed.
+  - the discovered pre-existing tmux loader-marker race was reproduced with constructor PID
+    evidence, fixed with a pane readiness/FIFO barrier, passed 3 consecutive focused runs, and passed
+    in the full shell harness.
+  - one combined rerun encountered the separate existing real-lease probe TOCTOU in
+    `install-ordering-guard.spec.ts`; an earlier final Vitest run was fully green and the changed
+    focused suites remained green.
+- Gateway safe baseline excluding the prohibited PostgreSQL-only fixture: 55 files / 600 tests passed
+  (6 files / 12 tests skipped by their existing environment gates).
+- Root `pnpm test` reached 43 successful workspace tasks and all changed-package Vitest tests, but
+  the unchanged `apps/gateway/src/__tests__/cross-user-isolation.test.ts` afterAll hook retried a
+  PostgreSQL connection and failed authentication (`28P01`). This checkout explicitly forbids local
+  PostgreSQL startup/access; the failure is unrelated to #1150 and cannot be remediated by starting
+  the database. The gateway suite excluding that PostgreSQL-only file and required CI are used as
+  the safe verification paths.
+
+### Independent review
+
+- Codex code review: approved, 0 findings across 15 files.
+- Initial Codex security review: one medium CWE-532/A09 finding for raw report persistence.
+- Remediation added central credential-pattern redaction, prompt/docs guidance, canary tests, typed
+  field false-positive guards, and sticky fail-closed restore for credential-bearing append-only
+  history.
+- Codex security re-review: risk `none`, 0 findings, confidence 0.87.
+- Focused remediation review findings were fixed; final focused re-review verdict: `APPROVE`.
+- Focused independent review of the tmux readiness barrier: `APPROVE`, no actionable findings.
+
+## Risks and blockers
+
+- Live `~/.config/mosaic` is shared by active Pi/fleet processes. Local deployment remained a single
+  additive framework file and did not reload or restart unrelated sessions.
+- Completion verification is semantic, not mathematical: the active agent supplies structured
+  evidence twice. Operators must still inspect consequential outcomes.
+- Credential redaction is pattern-based defense-in-depth, not a secret store. It covers
+  controller-owned state/status/tool details, not Pi's separate model-message/tool-call history.
+  Goals and reports must never contain real secrets or raw sensitive output. Because Pi session
+  entries are append-only, a detected credential-bearing legacy branch fails closed and the affected
+  session must be removed.
+- Current installed Pi is newer than the repository's historical gateway Pi dependency. The
+  extension was checked and smoke-tested against installed Pi 0.84.1 using stable documented APIs.
+- Local root testing cannot safely execute the unchanged PostgreSQL-only integration fixture under
+  the checkout's explicit database safety constraints. Terminal-green PR CI remains mandatory before
+  merge.
+- The unchanged real-lease default-probe test can observe different broker availability across its two
+  sequential probes; one combined package rerun hit that existing TOCTOU. The same final Vitest suite
+  passed in a separate run, and CI remains the merge authority.

+# #1174 — Wrapper guard rounds 10–11
+
+## Objective
+
+Make checkout enforcement judge Git placement operands rather than every HOME-shaped word in the command, without reopening `--separate-git-dir` placement under HOME.
+
+## Plan
+
+1. Reproduce the four over-blocks and the placement-option control at head `20d86e39`.
+2. Add RED fixtures before production changes.
+3. Extract clone/worktree placement operands from the existing shell-aware normalized stream.
+4. Run the full guard corpus, historical-head discrimination, syntax/static checks, probes, review, and CI.
+
+## Progress and evidence
+
+- Reproduced: `NOTE=$HOME`, `--reference=$HOME`, `GIT_DIR=$HOME/x`, and `--template=$HOME/t` all blocked despite explicit `/src/wt` destinations.
+- RED at `20d86e39`: expanded suite had 8 failures, all HOME-valued non-placement cases.
+- GREEN: expanded suite passes 242/242.
+- Round-10 probes: 7/7 placement expectations and 4/4 placement-option controls pass.
+- Earlier path probes remain green: 60/60, 24/24, and 17/17.
+- Historical discrimination with the 242-fixture suite:
+  - `3d0a882a`: 216 pass / 26 fail.
+  - `4b8eba95`: 222 pass / 20 fail.
+  - `20d86e39`: 234 pass / 8 fail.
+- `bash -n`, ShellCheck warning-or-higher, and `git diff --check`: pass.
+
+## Residual / risk
+
+- Relative destinations whose effective path depends on cwd are tracked separately by #1197 and remain out of scope.
+- Unknown future Git options with a separate following value fail closed when that value is HOME-shaped. This may require classification when Git adds an unrelated path-taking option, but prevents a new placement option from silently bypassing the guard.
+
+## Round 11 objective and intake
+
+- **Issue / PR:** #1174.
+- **Objective:** Remove the finite boolean-flag allowlists that turn accepted clone/worktree flags into fake placement operands, while preserving all real HOME placement blocks.
+- **Scope:** `wrapper-guard.sh`, its hermetic fixtures, and task documentation. Relative cwd-dependent destinations remain in #1197.
+- **Surfaces:** security-sensitive Bash hook behavior and shell/Git option grammar; no API, DB, UI, auth, deploy, or dependency changes.
+- **Budget assumption:** 25K working tokens; reduce exploratory matrices before reducing acceptance coverage.
+
+### Round 11 plan
+
+1. Use Git itself to classify accepted/rejected clone and worktree options, and Bash itself to resolve path-word expectations.
+2. Add RED fixtures for all six reported clone flags, generated negations, and equivalent worktree grammar.
+3. Replace the open-ended unknown-option fail-closed fallback with a parser based on the closed value-taking option surface; keep explicit placement options special.
+4. Run the full corpus, historical discrimination, shell/static checks, targeted probes, independent code/security review, one push, and exact-head CI.
+
+### Root-cause evidence
+
+- Git 2.39.5 accepts all six reported clone flags and the broader generated family measured in the brief: `--bare`, `--mirror`, `--ipv4`, `--ipv6`, `-4`, `-6`, `--no-local`, `--no-reject-shallow`, `--no-bare`, `--no-sparse`, `--no-dissociate`, `--no-shallow-submodules`, `--no-quiet`, `--no-progress`, and `--no-recurse-submodules`; it rejects `--relative-paths` as unknown.
+- Git 2.39.5 accepts worktree negations including `--no-force`, `--no-detach`, `--no-lock`, `--no-guess-remote`, and `--no-track`; the current finite worktree flag list does not describe that generated family.
+- `bash -c "printf '%s' <word>"` resolves `$HOME/source`, `${HOME}/source`, and `"$HOME"/source` under HOME while `/src/wt` remains outside it.
+- **Hypothesis:** only separate-value options need positive classification. Treat every other option token as a no-value flag unless it is the explicit placement option; this matches Git's non-enumerable boolean family and confines the residual to genuinely new future value-taking options.
+
+### TDD and verification checkpoints
+
+- RED against the unmodified `91cc37bc` guard: 253 pass / 22 fail in the initial expanded 275-fixture suite. Failures include all 15 accepted clone flags, accepted long abbreviations, short value-taking bundles, abbreviated placement, worktree metadata abbreviation, and both directions of bundled worktree branch parsing.
+- An exploratory fail-closed residual test drove emission of every worktree positional. Re-review correctly showed that this over-blocked HOME-shaped commit-ish metadata; a new commit-ish fixture failed RED against that intermediate implementation (278 pass / 2 fail, including one transient message assertion) and the parser was restored to emit only the actual path.
+- GREEN after remediation: 280/280.
+- Ultron's 13-shape option probe: 13/13 correct, including the six reported over-blocks, HOME destinations, end-of-options, worktree controls, and a later-command placement.
+- Round-10 probes remain green: 7/7 subject-placement expectations and 4/4 `--separate-git-dir` controls.
+- Earlier shell/path probes remain green: 60/60, 24/24, and 17/17.
+- `bash -n`, ShellCheck warning-or-higher, and `git diff --check`: pass.
+
+### Deliberate residual
+
+A future Git release could add a new separate-value option absent from the closed value grammar. It defaults to no-value flag parsing, which leaves the following word positional. For clone, this can fail open if that future option itself creates repository state at its value. For worktree, it can shift which word is read as the path. This hypothetical future ambiguity is accepted deliberately because failing closed on every unclassified option is proven to over-block Git's open-ended present-day boolean/`--no-*` family. Every value-taking and placement option Git currently supports is classified, including accepted abbreviations of `--separate-git-dir`. Relative cwd-dependent targets remain in #1197.
+
+### Independent review checkpoint
+
+- Initial Codex code/security review raised `--orphan` as value-taking. Upstream Git `master` contradicts that premise: the synopsis is `[--orphan] [(-b | -B) <new-branch>] <path> [<commit-ish>]`, and the prose derives the branch from the path when `-b`/`-B` is absent. `--orphan` is therefore correctly handled as a boolean flag.
+- The security review separately identified the generic future worktree shift residual. An attempted fail-closed remediation emitted every positional, but code re-review correctly rejected it because valid grammar has only one placement positional and an optional commit-ish. Final behavior checks only the path and documents the hypothetical future option shift deliberately; paired actual-grammar `--orphan` fixtures cover safe/HOME paths and `-b` metadata.
+- Security re-review initially had no findings. Code re-review's commit-ish blocker was remediated with a RED fixture and path-only restoration; final code re-review approved with no findings.
+- Final security review then found non-canonical absolute and symlink aliases. Eight lexical fixtures failed RED against the prior implementation, followed by three symlink fixtures failing RED. Remediation expands only shell-visible HOME tokens, resolves the longest existing directory prefix physically, and lexically normalizes the nonexistent suffix. The suite is now 292/292.
+- Inherent residual: a symlink can be replaced between pre-tool inspection and Git execution. Existing aliases are resolved; eliminating the race requires enforcement inside the filesystem mutation path rather than a text pre-hook. Security review classified this medium, and architectural closure is tracked in #1199.
+- Final independent code review: APPROVE, 0 findings. Final security review: no critical/high findings; the single medium TOCTOU residual is explicitly tracked in #1199.
+
+### Final local evidence
+
+- Final hermetic suite: 292/292; the same suite against `91cc37bc` discriminates at 256 pass / 36 fail.
+- Ultron option probe: 13/13; round-10 probes: 7/7 plus 4/4 controls; earlier shell/path probes: 60/60, 24/24, and 17/17.
+- `bash -n`, ShellCheck warning-or-higher, `git diff --check`, sanitization gate, and test-enumeration gate (population 55; 38 enumerated; 18 signed exclusions): pass.
+- Independent code review: APPROVE, 0 findings. Security review's remaining medium TOCTOU architecture residual is tracked in #1199; no critical/high findings remain.
+- Repository-wide TypeScript gates require dependencies absent from this worktree; the canonical Woodpecker pipeline will run them against the pushed exact head.
+
+### Documentation checklist
+
+- `docs/PRD.md` updated with WPG requirements, acceptance, canonicalization, and residual risk.
+- Task scratchpad updated in the same logical change set; `docs/TASKS.md` remains orchestrator-only.
+- No API, auth, UI, navigation, deployment, user-guide, or admin-guide surface changed; OpenAPI, endpoint index, sitemap, and publishing are not applicable.

+# #1179 — Required security DI wiring
+
+## Objective
+
+Eliminate the shared fail-open defect class **absence read as permission**:
+
+- FL-01: missing `CommandAuthorizationService` must refuse Nest startup and must not permit command effects.
+- FL-11: missing `SystemOverrideService` must refuse Nest startup and must not omit stored instruction authority while allowing provider/session effects.
+
+## Tracking
+
+- Issue: #1179, child of #1156
+- Branch: `fix/1179-required-security-di`
+- Base: `origin/next` at `216cd72226cd9ee17eea461cfe7cd0e010a22f02`
+
+## Plan
+
+1. RED: compile the real `AppModule` graph with each required provider independently removed, with a positive control for each intact binding.
+2. RED: directly exercise each malformed absence path and assert zero command/provider/session effects.
+3. Stop and report RED to the coordinator before production implementation.
+4. After authorization, make both constructor injections required, remove absence-as-permission branches, and update explicit legitimate optional test seams.
+5. Run focused Gateway tests, typecheck, lint, format, build, independent exact-head verification, and focused security review.
+
+## Immutable path fence
+
+Production changes are confined to:
+
+- `apps/gateway/src/commands/command-executor.service.ts`
+- `apps/gateway/src/agent/agent.service.ts`
+
+Tests and task evidence are confined to:
+
+- `apps/gateway/src/__tests__/required-security-wiring.test.ts`
+- existing direct-constructor specs that require explicit required arguments
+- `docs/scratchpads/1179-required-security-di.md`
+
+No files in #1178, #1072, #1080, or #1054 lanes are in scope. `docs/TASKS.md` is orchestrator-owned and will not be modified.
+
+## Budget
+
+No explicit token ceiling was provided. Working assumption: one narrow Gateway security packet; split and stop if either arm requires unrelated module rewiring.
+
+## Progress
+
+- Intake read from #1179 and parent #1156.
+- Base independently resolved from the issue's pre-native-stage ordering and repository `origin/next` ref; branch HEAD verified byte-for-byte against the remote ref.
+- Real consumers and direct constructors inventoried.
+

+- `AgentModule` / `CommandsModule` / `ChatModule` contain a production cycle; the module test therefore uses the real top-level `AppModule` and replaces only storage/network leaves, preserving the target service in each arm while isolating the separate required consumer that would otherwise mask that arm's defect.
+- No broad module rewrite was required.

+# #1194 — Installed framework-tool drift detection and refresh analysis
+
+## Decision
+
+The reported queue-guard source defect was already fixed on `main` by `58b971ab`; the live failure came from a stale `~/.config/mosaic/tools/git/ci-queue-wait.sh`. The durable fix is therefore a detector, not a duplicate queue-guard patch.
+
+`mosaic doctor` now compares the framework tools bundled with the executing Mosaic package against the deployed tools tree. Doctor is the selected visibility boundary because it is observational and operator-invoked: unlike session start, it does not add a repository/network scan to every seat launch, and it cannot silently replace identity or messaging tools while seats are active. It reports drift without changing files. `--fail-on-warn` converts detected drift into a non-zero doctor result.
+
+## Classification
+
+The existing `framework-manifest.txt` is authoritative. The detector invokes the canonical shared `tools/_lib/manifest.sh classify` implementation over the complete source census and refuses missing, unreadable, malformed, incomplete, or zero-framework ownership output. Policy is therefore read rather than duplicated:
+
+- Current policy classifies source files under `tools/**` as framework-owned and required in the deployed tools tree.
+- Current policy explicitly classifies `tools/_lib/credentials.json` operator-owned and excludes it from byte comparison; future policy changes take effect without a detector edit.
+- A file present only in the deployed tools tree is operator-owned/unknown by the manifest's fail-safe default. The detector reports it as `INSTALLED_ONLY operator-or-unknown` under `--verbose` but does not fail or delete it.
+- Empty/partial source traversal, unreadable directories/files, symlinked census entries, root aliases, and descendant source aliases all return `CANNOT_ASSERT` rather than manufacturing agreement.
+
+This means `NOT_INSTALLED` is not suppressed by filename guesses such as “test” or “README”: if it ships below source `tools/**`, the installer contract says it should be installed. Source-only implementation files outside `tools/**` are outside this detector population by construction.
+
+## Current host analysis (observation only; no refresh performed)
+
+A direct source-vs-installed census showed broad drift, including identity and messaging behavior:
+
+- Identity/provider operations: stale `git/detect-platform.sh`, `issue-comment.sh`, `issue-create.sh`, `issue-close.sh`, `issue-view.sh`, `pr-create.sh`, `pr-merge.sh`, `pr-review.sh`, `pr-metadata.sh`; missing `pr-edit.sh` and several identity/read-back regression tools.
+- Messaging/session: stale `tmux/agent-send.sh`, `tmux/send-message.sh`, their regressions, and `fleet/start-agent-session.sh`.
+- Gate enforcement: stale `git/ci-queue-wait.sh`; missing the queue tri-state/process-level suites and terminal-green verifier.
+- Lease/QA behavior: stale lease-broker launch/mutation/receipt tools and QA hooks.
+
+Counts vary with source head and installed local/operator files; the detector prints measured counts every run rather than baking this snapshot into policy.
+
+## Reviewed refresh command — analyse only, do not run during active seats
+
+Use the package/release updater's manifest-driven keep-mode sync during a quiet maintenance window:
+
+```bash
+MOSAIC_SYNC_ONLY=1 \
+MOSAIC_INSTALL_MODE=keep \
+MOSAIC_HOME="$HOME/.config/mosaic" \
+bash /path/to/reviewed/@mosaicstack/mosaic/framework/install.sh
+```
+
+For the globally installed package, resolve the reviewed installer rather than guessing its path:
+
+```bash
+PACKAGE_ROOT="$(dirname "$(node -p "require.resolve('@mosaicstack/mosaic/package.json')")")"
+MOSAIC_SYNC_ONLY=1 MOSAIC_INSTALL_MODE=keep MOSAIC_HOME="$HOME/.config/mosaic" \
+  bash "$PACKAGE_ROOT/framework/install.sh"
+```
+
+Do not run this while agent seats are active: the stale set includes identity selection, provider mutation, messaging, queue/merge guards, lease enforcement, and session launch. Syncing those files in place can change behavior between a seat's preflight and mutation.
+
+## Post-refresh verification
+
+1. Run `mosaic doctor --fail-on-warn`; require `stale=0 not-installed=0` from the framework drift summary (other unrelated doctor warnings must also be adjudicated).
+2. Re-run the constructed process-level queue probes against the **installed path**, not the source checkout. Use the source suite while overriding its subject path in a reviewed scratch copy, or reproduce these exact observations:
+   - pending provider payload: guard must print `state=pending`, print the pending context, wait, and exit non-zero/timeout — never return immediately with rc 0;
+   - malformed payload: guard must print `state=malformed` and exit non-zero;
+   - unsupported but valid status vocabulary: guard must print `state=unknown` and exit non-zero.
+3. Run provider author read-back for one deliberately low-risk wrapper operation before resuming fleet mutation work; wrapper self-report is not identity evidence.
+4. Relaunch seats only after the quiet-window verification, because existing processes retain loaded environment/context.
+
+## Probe evidence
+
+The detector regression constructs a stale installed tool plus a missing shipped tool and observes rc 1 with distinct `STALE` and `NOT_INSTALLED` lines. That case would pass or be invisible before this change because no installed-vs-shipped comparison existed. Additional review-red controls prove:
+
+- empty and unreadable source censuses return `CANNOT_ASSERT` (they returned clean rc 0 at the first PR head);
+- deleting the manifest returns `CANNOT_ASSERT`, while changing manifest ownership changes the verdict through the canonical resolver (the first head never opened the manifest);
+- root and descendant symlink/source aliases cannot return clean (the first head returned clean for a source-backed installed subtree);
+- a checker hung during doctor is terminated by a bounded watchdog, emits `CANNOT_ASSERT`, and doctor reaches its final warnings line (the first head hung and suppressed the remaining audit).
+
+Controls retain byte-identical success, exact credential carve-out behavior, and installed-only preservation.

+## Model Tiering
+
+Model choice is a standard, not a preference. Delegating a mechanical grep to a
+frontier reasoning model wastes budget; sending a security review to a cheap tier
+produces a review that passes and proves nothing. Both are defects.
+
+Tiers are named by **capability class**, so the standard survives a model
+generation. An operator binds each class to a concrete model id.
+
+| Class         | Use for                                                                                   |
+| ------------- | ----------------------------------------------------------------------------------------- |
+| `search`      | grep/glob, file location, status and health checks, one-line mechanical edits             |
+| `build`       | feature implementation, test writing, bugfixes, routine refactors                         |
+| `judge`       | code review, planning, API/compat-sensitive changes                                       |
+| `adversarial` | security review, ambiguous architecture, anything where a wrong "looks fine" is expensive |
+
+Rules:
+
+1. **Start at the cheapest class that can do the task; escalate on evidence, not
+   on nerves.** Omitting a tier is not neutral — it inherits the caller's model,
+   which is usually the most expensive one.
+2. **Compat-sensitive work escalates one class.** A change that must interoperate
+   with an existing contract is judged, not just built.
+3. **A tier assignment is benchmarked, not asserted.** Move a task class to a
+   cheaper tier only against a blind A/B on real work from this codebase, ranked
+   by someone other than the author. "It seemed fine" is not evidence.
+4. **Reviewer independence beats reviewer size.** An `adversarial` verdict from
+   the model that wrote the code is not a second opinion (see Constitution gate 16).
+
+### Where the binding lives
+
+The class→model map is operator configuration, never framework source: model
+availability, cost, and quotas differ per operator and per host.
+
+Resolution order, first hit wins:
+
+1. the config service (DB-backed, surfaced and editable in the Mosaic webUI)
+2. a local operator file (`STANDARDS.local.md`, or `policy/` where the runtime
+   injects it)
+3. the framework default — the class names above, with no binding
+
+Only layer 1 is auditable across a fleet, so it is the target end state; layers 2
+and 3 exist so a host with no config service still runs. A local override that
+silently disagrees with the config service is drift — the same failure class the
+tool-index gate exists to catch, and it belongs in `mosaic doctor`.

+Worktrees rather than clones, because `git worktree list` makes every checkout enumerable — a bare
+clone dropped somewhere on disk can never be safely reclaimed, so it is never reclaimed. `rm` and
+`gc` decide by **evidence, never by size or age**: a worktree is reclaimable only when
+`git status --porcelain` is empty _and_ `git rev-list --count HEAD --not --remotes` is 0. Anything
+else is preserved and reported. `--force` exists and is yours to type deliberately.

+`wrapper-guard.sh` is registered as a Claude Code `PreToolUse` hook on `Bash` (see
+`runtime/claude/settings.json`). It blocks exactly three things and lets everything else through:
+a `git clone`/`git worktree add` targeting `$HOME`; a raw provider-API **write** to an endpoint that
+already has a wrapper above (reads are untouched — they are how you gather evidence); and the
+literal `"event": "APPROVE"`. For a genuine gap no wrapper can express, prefix
+`MOSAIC_WRAPPER_OVERRIDE=1`. Reaching for the override twice for the same call means the wrapper has
+a missing flag — extend the wrapper.
+
+```bash
+~/.config/mosaic/tools/git/issue-create.sh --help
+~/.config/mosaic/tools/git/pr-review.sh --pr 42 --event APPROVED --body "..."
 
 # CI queue guard (required before push/merge; defaults to the checked-out branch)
 ~/.config/mosaic/tools/git/ci-queue-wait.sh --purpose push|merge
 ```
 
+**Review dialect — the reason `pr-review.sh` is not optional.** Gitea's approve event is
+`APPROVED`; GitHub's is `APPROVE`. Send GitHub's spelling to a Gitea host and it answers **HTTP
+200**, files the review as PENDING, and then rejects the submit with `422 review stay pending` — the
+verdict looks placed and is not. (`REQUEST_CHANGES` is spelled identically on both, so only the
+approve path carries the trap.) `pr-review.sh` sends the correct token for the detected provider.
+Whatever you use, re-read `GET /pulls/{n}/reviews` and assert the state before reporting a verdict
+placed.
+
 The guard exits nonzero for any provider-asserted non-green, missing, or malformed CI state. If credentials or the provider are unavailable, it emits `CANNOT_ASSERT` and writes a JSONL audit record. Push degrades to exit 0 so recovery work is not bricked; merge holds with retryable exit 75 until the provider recovers, then self-clears without manual reset. Neither outcome is evidence that CI was clear. `pr-merge.sh` automatically inspects the exact PR head repository and full commit SHA rather than its `main` base; this also handles fork PRs without branch-name ambiguity. Pass `--expect-head <approved-full-sha>` to bind a commit-specific review or merge-gate verdict; Gitea uses atomic `head_commit_id` and GitHub uses `--match-head-commit`.

 ### Extensions
 
-The Mosaic Pi extension (`~/.config/mosaic/runtime/pi/mosaic-extension.ts`) handles:
+`mosaic pi` loads framework-owned extensions directly from `~/.config/mosaic/runtime/pi/` in this
+order:
 
-- Session start/end lifecycle hooks
-- Active mission detection and context injection
-- Memory routing to `~/.config/mosaic/memory/`
-- MACP queue status reporting
+1. `mosaic-extension.ts` — session lifecycle, mission context, memory routing, lease/mutator gates,
+   and fleet heartbeat reporting.
+2. `goal-extension.ts` — optional persistent `/goal` controller with per-turn and post-compaction
+   checks.
+
+The goal extension is deployed by Mosaic and MUST NOT be copied into `~/.pi/agent/extensions/`.
+Use `/goal set <statement>` (or `/goal <statement>`) to start, then `/goal status`, `/goal pause`,
+`/goal resume`, or `/goal cancel` to control it. An active goal is injected before every model
+request, restored from branch-specific session entries, and considered achieved only after two
+consecutive evidence-bearing reports. Common credential shapes are redacted before controller-owned
+goal-state entries are persisted or
+displayed; Pi's own model/tool-call history is separate. Goals and reports must contain references
+and pass/fail summaries rather than secrets or raw sensitive output.

+
+## Installation
+
+The skills ship with the framework package. The framework installer installs them
+into `~/.config/mosaic/skills/`, and the post-install step links them into each
+runtime's skill directory:
+
+```bash
+# Install or upgrade the framework (skills arrive with it — no second repo)
+./packages/mosaic/framework/install.sh
+
+# Re-link installed skills into runtime homes (claude, codex, opencode, pi)
+mosaic sync
+```
+
+Operators can override any canonical skill by copying it to
+`~/.config/mosaic/skills-local/<name>/` — local skills take precedence during
+linking.
+
+## Adapting Skills
+
+When adding skills from the community:
+
+1. Replace raw `gh`/`tea` calls with our `~/.config/mosaic/rails/git/` scripts
+2. Test on both GitHub and Gitea repos
+3. Add Mosaic Stack context notes where upstream assumptions differ
+4. Document any platform-specific limitations
+
+## License
+
+Individual skills retain their original licenses. Adaptations are MIT.

+name: ab-test-setup
+version: 1.0.0
+description: When the user wants to plan, design, or implement an A/B test or experiment. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," or "hypothesis." For tracking implementation, see analytics-tracking.
+---
+
+# A/B Test Setup
+
+You are an expert in experimentation and A/B testing. Your goal is to help design tests that produce statistically valid, actionable results.
+
+## Initial Assessment
+
+**Check for product marketing context first:**
+If `.mosaic/product-marketing-context.md` exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
+
+Before designing a test, understand:
+
+1. **Test Context** - What are you trying to improve? What change are you considering?
+2. **Current State** - Baseline conversion rate? Current traffic volume?
+3. **Constraints** - Technical complexity? Timeline? Tools available?
+
+---
+
+## Core Principles
+
+### 1. Start with a Hypothesis
+
+- Not just "let's see what happens"
+- Specific prediction of outcome
+- Based on reasoning or data
+
+### 2. Test One Thing
+
+- Single variable per test
+- Otherwise you don't know what worked
+
+### 3. Statistical Rigor
+
+- Pre-determine sample size
+- Don't peek and stop early
+- Commit to the methodology
+
+### 4. Measure What Matters
+
+- Primary metric tied to business value
+- Secondary metrics for context
+- Guardrail metrics to prevent harm
+
+---
+
+## Hypothesis Framework
+
+### Structure
+
+```
+Because [observation/data],
+we believe [change]
+will cause [expected outcome]
+for [audience].
+We'll know this is true when [metrics].
+```
+
+### Example
+
+**Weak**: "Changing the button color might increase clicks."
+
+**Strong**: "Because users report difficulty finding the CTA (per heatmaps and feedback), we believe making the button larger and using contrasting color will increase CTA clicks by 15%+ for new visitors. We'll measure click-through rate from page view to signup start."
+
+---
+
+## Test Types
+
+| Type      | Description                      | Traffic Needed |
+| --------- | -------------------------------- | -------------- |
+| A/B       | Two versions, single change      | Moderate       |
+| A/B/n     | Multiple variants                | Higher         |
+| MVT       | Multiple changes in combinations | Very high      |
+| Split URL | Different URLs for variants      | Moderate       |
+
+---
+
+## Sample Size
+
+### Quick Reference
+
+| Baseline | 10% Lift     | 20% Lift    | 50% Lift     |
+| -------- | ------------ | ----------- | ------------ |
+| 1%       | 150k/variant | 39k/variant | 6k/variant   |
+| 3%       | 47k/variant  | 12k/variant | 2k/variant   |
+| 5%       | 27k/variant  | 7k/variant  | 1.2k/variant |
+| 10%      | 12k/variant  | 3k/variant  | 550/variant  |

+
+---
+
+## Metrics Selection
+
+### Primary Metric
+
+- Single metric that matters most
+- Directly tied to hypothesis
+- What you'll use to call the test
+
+### Secondary Metrics
+
+- Support primary metric interpretation
+- Explain why/how the change worked
+
+### Guardrail Metrics
+
+- Things that shouldn't get worse
+- Stop test if significantly negative
+
+### Example: Pricing Page Test
+
+- **Primary**: Plan selection rate
+- **Secondary**: Time on page, plan distribution
+- **Guardrail**: Support tickets, refund rate
+
+---
+
+## Designing Variants
+
+### What to Vary
+
+| Category       | Examples                                          |
+| -------------- | ------------------------------------------------- |
+| Headlines/Copy | Message angle, value prop, specificity, tone      |
+| Visual Design  | Layout, color, images, hierarchy                  |
+| CTA            | Button copy, size, placement, number              |
+| Content        | Information included, order, amount, social proof |
+
+### Best Practices
+
+- Single, meaningful change
+- Bold enough to make a difference
+- True to the hypothesis
+
+---
+
+## Traffic Allocation
+
+| Approach     | Split                 | When to Use               |
+| ------------ | --------------------- | ------------------------- |
+| Standard     | 50/50                 | Default for A/B           |
+| Conservative | 90/10, 80/20          | Limit risk of bad variant |
+| Ramping      | Start small, increase | Technical risk mitigation |
+
+**Considerations:**
+
+- Consistency: Users see same variant on return
+- Balanced exposure across time of day/week
+
+---
+
+## Implementation
+
+### Client-Side
+
+- JavaScript modifies page after load
+- Quick to implement, can cause flicker
+- Tools: PostHog, Optimizely, VWO
+
+### Server-Side
+
+- Variant determined before render
+- No flicker, requires dev work
+- Tools: PostHog, LaunchDarkly, Split
+
+---
+
+## Running the Test
+
+### Pre-Launch Checklist
+
+- [ ] Hypothesis documented
+- [ ] Primary metric defined
+- [ ] Sample size calculated
+- [ ] Variants implemented correctly
+- [ ] Tracking verified
+- [ ] QA completed on all variants
+
+### During the Test
+
+**DO:**
+
+- Monitor for technical issues
+- Check segment quality
+- Document external factors
+
+**DON'T:**
+
+- Peek at results and stop early
+- Make changes to variants
+- Add traffic from new sources
+
+### The Peeking Problem
+
+Looking at results before reaching sample size and stopping early leads to false positives and wrong decisions. Pre-commit to sample size and trust the process.
+
+---
+
+## Analyzing Results
+
+### Statistical Significance
+
+- 95% confidence = p-value < 0.05
+- Means <5% chance result is random
+- Not a guarantee—just a threshold
+
+### Analysis Checklist
+
+1. **Reach sample size?** If not, result is preliminary
+2. **Statistically significant?** Check confidence intervals
+3. **Effect size meaningful?** Compare to MDE, project impact
+4. **Secondary metrics consistent?** Support the primary?
+5. **Guardrail concerns?** Anything get worse?
+6. **Segment differences?** Mobile vs. desktop? New vs. returning?
+
+### Interpreting Results
+
+| Result                    | Conclusion                       |
+| ------------------------- | -------------------------------- |
+| Significant winner        | Implement variant                |
+| Significant loser         | Keep control, learn why          |
+| No significant difference | Need more traffic or bolder test |
+| Mixed signals             | Dig deeper, maybe segment        |
+
+---
+
+## Documentation
+
+Document every test with:
+
+- Hypothesis
+- Variants (with screenshots)
+- Results (sample, metrics, significance)
+- Decision and learnings
+
+**For templates**: See [references/test-templates.md](references/test-templates.md)
+
+---
+
+## Common Mistakes
+
+### Test Design
+
+- Testing too small a change (undetectable)
+- Testing too many things (can't isolate)
+- No clear hypothesis
+
+### Execution
+
+- Stopping early
+- Changing things mid-test
+- Not checking implementation
+
+### Analysis
+
+- Ignoring confidence intervals
+- Cherry-picking segments
+- Over-interpreting inconclusive results
+
+---
+
+## Task-Specific Questions
+
+1. What's your current conversion rate?
+2. How much traffic does this page get?
+3. What change are you considering and why?
+4. What's the smallest improvement worth detecting?
+5. What tools do you have for testing?
+6. Have you tested this area before?

+# Sample Size Guide
+
+Reference for calculating sample sizes and test duration.
+
+## Sample Size Fundamentals
+
+### Required Inputs
+
+1. **Baseline conversion rate**: Your current rate
+2. **Minimum detectable effect (MDE)**: Smallest change worth detecting
+3. **Statistical significance level**: Usually 95% (α = 0.05)
+4. **Statistical power**: Usually 80% (β = 0.20)
+
+### What These Mean
+
+**Baseline conversion rate**: If your page converts at 5%, that's your baseline.
+
+**MDE (Minimum Detectable Effect)**: The smallest improvement you care about detecting. Set this based on:
+
+- Business impact (is a 5% lift meaningful?)
+- Implementation cost (worth the effort?)
+- Realistic expectations (what have past tests shown?)
+
+**Statistical significance (95%)**: Means there's less than 5% chance the observed difference is due to random chance.
+
+**Statistical power (80%)**: Means if there's a real effect of size MDE, you have 80% chance of detecting it.

+
+## Duration Calculator
+
+### Formula
+
+```
+Duration (days) = (Sample per variant × Number of variants) / (Daily traffic × % exposed)
+```
+
+### Examples
+
+**Scenario 1: High-traffic page**
+
+- Need: 10,000 per variant (2 variants = 20,000 total)
+- Daily traffic: 5,000 visitors
+- 100% exposed to test
+- Duration: 20,000 / 5,000 = **4 days**
+
+**Scenario 2: Medium-traffic page**
+
+- Need: 30,000 per variant (60,000 total)
+- Daily traffic: 2,000 visitors
+- 100% exposed
+- Duration: 60,000 / 2,000 = **30 days**
+
+**Scenario 3: Low-traffic with partial exposure**
+
+- Need: 15,000 per variant (30,000 total)
+- Daily traffic: 500 visitors
+- 50% exposed to test
+- Effective daily: 250
+- Duration: 30,000 / 250 = **120 days** (too long!)
+
+### Minimum Duration Rules
+
+Even with sufficient sample size, run tests for at least:
+
+- **1 full week**: To capture day-of-week variation
+- **2 business cycles**: If B2B (weekday vs. weekend patterns)
+- **Through paydays**: If e-commerce (beginning/end of month)
+
+### Maximum Duration Guidelines
+
+Avoid running tests longer than 4-8 weeks:
+
+- Novelty effects wear off
+- External factors intervene
+- Opportunity cost of other tests

+
+## Adjusting for Multiple Variants
+
+With more than 2 variants (A/B/n tests), you need more sample:
+
+| Variants    | Multiplier                 |
+| ----------- | -------------------------- |
+| 2 (A/B)     | 1x                         |
+| 3 (A/B/C)   | ~1.5x                      |
+| 4 (A/B/C/D) | ~2x                        |
+| 5+          | Consider reducing variants |
+
+**Why?** More comparisons increase chance of false positives. You're comparing:
+
+- A vs B
+- A vs C
+- B vs C (sometimes)
+
+Apply Bonferroni correction or use tools that handle this automatically.
+
+---
+
+## Common Sample Size Mistakes
+
+### 1. Underpowered tests
+
+**Problem**: Not enough sample to detect realistic effects
+**Fix**: Be realistic about MDE, get more traffic, or don't test
+
+### 2. Overpowered tests
+
+**Problem**: Waiting for sample size when you already have significance
+**Fix**: This is actually fine—you committed to sample size, honor it
+
+### 3. Wrong baseline rate
+
+**Problem**: Using wrong conversion rate for calculation
+**Fix**: Use the specific metric and page, not site-wide averages
+
+### 4. Ignoring segments
+
+**Problem**: Calculating for full traffic, then analyzing segments
+**Fix**: If you plan segment analysis, calculate sample for smallest segment
+
+### 5. Testing too many things
+
+**Problem**: Dividing traffic too many ways
+**Fix**: Prioritize ruthlessly, run fewer concurrent tests
+
+---
+
+## When Sample Size Requirements Are Too High
+
+Options when you can't get enough traffic:
+
+1. **Increase MDE**: Accept only detecting larger effects (20%+ lift)
+2. **Lower confidence**: Use 90% instead of 95% (risky, document it)
+3. **Reduce variants**: Test only the most promising variant
+4. **Combine traffic**: Test across multiple similar pages
+5. **Test upstream**: Test earlier in funnel where traffic is higher
+6. **Don't test**: Make decision based on qualitative data instead
+7. **Longer test**: Accept longer duration (weeks/months)
+
+---
+
+## Sequential Testing
+
+If you must check results before reaching sample size:
+
+### What is it?
+
+Statistical method that adjusts for multiple looks at data.
+
+### When to use
+
+- High-risk changes
+- Need to stop bad variants early
+- Time-sensitive decisions
+
+### Tools that support it
+
+- Optimizely (Stats Accelerator)
+- VWO (SmartStats)
+- PostHog (Bayesian approach)
+
+### Tradeoff
+
+- More flexibility to stop early
+- Slightly larger sample size requirement
+- More complex analysis
+
+---
+
+## Quick Decision Framework
+
+### Can I run this test?
+
+```
+Daily traffic to page: _____
+Baseline conversion rate: _____
+MDE I care about: _____
+
+Sample needed per variant: _____ (from tables above)
+Days to run: Sample / Daily traffic = _____
+
+If days > 60: Consider alternatives
+If days > 30: Acceptable for high-impact tests
+If days < 14: Likely feasible
+If days < 7: Easy to run, consider running longer anyway

+description: 'Answer questions about the AI SDK and help build AI-powered features. Use when developers: (1) Ask about AI SDK functions like generateText, streamText, ToolLoopAgent, embed, or tools, (2) Want to build AI agents, chatbots, RAG systems, or text generation features, (3) Have questions about AI providers (OpenAI, Anthropic, Google, etc.), streaming, tool calling, structured output, or embeddings, (4) Use React hooks like useChat or useCompletion. Triggers on: "AI SDK", "Vercel AI SDK", "generateText", "streamText", "add AI to my app", "build an agent", "tool calling", "structured output", "useChat".'
+---
+
+## Prerequisites
+
+Before searching docs, check if `node_modules/ai/docs/` exists. If not, install **only** the `ai` package using the project's package manager (e.g., `pnpm add ai`).
+
+Do not install other packages at this stage. Provider packages (e.g., `@ai-sdk/openai`) and client packages (e.g., `@ai-sdk/react`) should be installed later when needed based on user requirements.
+
+## Critical: Do Not Trust Internal Knowledge
+
+Everything you know about the AI SDK is outdated or wrong. Your training data contains obsolete APIs, deprecated patterns, and incorrect usage.
+
+**When working with the AI SDK:**
+
+1. Ensure `ai` package is installed (see Prerequisites)
+2. Search `node_modules/ai/docs/` and `node_modules/ai/src/` for current APIs
+3. If not found locally, search ai-sdk.dev documentation (instructions below)
+4. Never rely on memory - always verify against source code or docs
+5. **`useChat` has changed significantly** - check [Common Errors](references/common-errors.md) before writing client code
+6. When deciding which model and provider to use (e.g. OpenAI, Anthropic, Gemini), use the Vercel AI Gateway provider unless the user specifies otherwise. See [AI Gateway Reference](references/ai-gateway.md) for usage details.
+7. **Always fetch current model IDs** - Never use model IDs from memory. Before writing code that uses a model, run `curl -s https://ai-gateway.vercel.sh/v1/models | jq -r '[.data[] | select(.id | startswith("provider/")) | .id] | reverse | .[]'` (replacing `provider` with the relevant provider like `anthropic`, `openai`, or `google`) to get the full list with newest models first. Use the model with the highest version number (e.g., `claude-sonnet-4-5` over `claude-sonnet-4` over `claude-3-5-sonnet`).
+8. Run typecheck after changes to ensure code is correct
+9. **Be minimal** - Only specify options that differ from defaults. When unsure of defaults, check docs or source rather than guessing or over-specifying.
+
+If you cannot find documentation to support your answer, state that explicitly.
+
+## Finding Documentation
+
+### ai@6.0.34+
+
+Search bundled docs and source in `node_modules/ai/`:
+
+- **Docs**: `grep "query" node_modules/ai/docs/`
+- **Source**: `grep "query" node_modules/ai/src/`
+
+Provider packages include docs at `node_modules/@ai-sdk/<provider>/docs/`.
+
+### Earlier versions
+
+1. Search: `https://ai-sdk.dev/api/search-docs?q=your_query`
+2. Fetch `.md` URLs from results (e.g., `https://ai-sdk.dev/docs/agents/building-agents.md`)
+
+## When Typecheck Fails
+
+**Before searching source code**, grep [Common Errors](references/common-errors.md) for the failing property or function name. Many type errors are caused by deprecated APIs documented there.
+
+If not found in common-errors.md:
+
+1. Search `node_modules/ai/src/` and `node_modules/ai/docs/`
+2. Search ai-sdk.dev (for earlier versions or if not found locally)
+
+## Building and Consuming Agents
+
+### Creating Agents
+
+Always use the `ToolLoopAgent` pattern. Search `node_modules/ai/docs/` for current agent creation APIs.
+
+**File conventions**: See [type-safe-agents.md](references/type-safe-agents.md) for where to save agents and tools.
+
+**Type Safety**: When consuming agents with `useChat`, always use `InferAgentUIMessage<typeof agent>` for type-safe tool results. See [reference](references/type-safe-agents.md).
+
+### Consuming Agents (Framework-Specific)
+
+Before implementing agent consumption:
+
+1. Check `package.json` to detect the project's framework/stack
+2. Search documentation for the framework's quickstart guide
+3. Follow the framework-specific patterns for streaming, API routes, and client integration

+title: Vercel AI Gateway
+description: Reference for using Vercel AI Gateway with the AI SDK.
+---
+
+# Vercel AI Gateway
+
+The Vercel AI Gateway is the fastest way to get started with the AI SDK. It provides access to models from OpenAI, Anthropic, Google, and other providers through a single API.
+
+## Authentication
+
+Authenticate with OIDC (for Vercel deployments) or an [AI Gateway API key](https://vercel.com/d?to=%2F%5Bteam%5D%2F%7E%2Fai-gateway%2Fapi-keys&title=AI+Gateway+API+Keys):
+
+```env filename=".env.local"
+AI_GATEWAY_API_KEY=your_api_key_here
+```
+
+## Usage
+
+The AI Gateway is the default global provider, so you can access models using a simple string:
+
+```ts
+import { generateText } from 'ai';
+
+const { text } = await generateText({
+  model: 'anthropic/claude-sonnet-4.5',
+  prompt: 'What is love?',
+});
+```
+
+You can also explicitly import and use the gateway provider:
+
+```ts
+// Option 1: Import from 'ai' package (included by default)
+import { gateway } from 'ai';
+model: gateway('anthropic/claude-sonnet-4.5');
+
+// Option 2: Install and import from '@ai-sdk/gateway' package
+import { gateway } from '@ai-sdk/gateway';
+model: gateway('anthropic/claude-sonnet-4.5');
+```
+
+## Find Available Models
+
+**Important**: Always fetch the current model list before writing code. Never use model IDs from memory - they may be outdated.
+
+List all available models through the gateway API:
+
+```bash
+curl https://ai-gateway.vercel.sh/v1/models
+```
+
+Filter by provider using `jq`. **Do not truncate with `head`** - always fetch the full list to find the latest models:
+
+```bash
+# Anthropic models
+curl -s https://ai-gateway.vercel.sh/v1/models | jq -r '[.data[] | select(.id | startswith("anthropic/")) | .id] | reverse | .[]'
+
+# OpenAI models
+curl -s https://ai-gateway.vercel.sh/v1/models | jq -r '[.data[] | select(.id | startswith("openai/")) | .id] | reverse | .[]'
+
+# Google models
+curl -s https://ai-gateway.vercel.sh/v1/models | jq -r '[.data[] | select(.id | startswith("google/")) | .id] | reverse | .[]'
+```
+
+When multiple versions of a model exist, use the one with the highest version number (e.g., prefer `claude-sonnet-4-5` over `claude-sonnet-4` over `claude-3-5-sonnet`).

+  prompt: 'List 5 capital cities',
+});
+
+// Output.choice - for selecting from predefined options
+const result = await generateText({
+  model: 'anthropic/claude-opus-4.5',
+  output: Output.choice({
+    options: ['positive', 'negative', 'neutral'] as const,
+  }),
+  prompt: 'Classify the sentiment: I love this product!',
+});
+
+// Output.json - for untyped JSON output
+const result = await generateText({

+  output: Output.json(),
+  prompt: 'Return some JSON data',
+});
+```
+
+## `toDataStreamResponse` → `toUIMessageStreamResponse`
+
+When using `useChat` on the frontend, use `toUIMessageStreamResponse()` instead of `toDataStreamResponse()`. The UI message stream format is designed to work with the chat UI components and handles message state correctly.
+
+```typescript
+// ❌ Incorrect (when using useChat)
+const result = streamText({
+  // config
+});
+
+return result.toDataStreamResponse(); // deprecated for useChat: use toUIMessageStreamResponse
+
+// ✅ Correct
+const result = streamText({
+  // config
+});
+
+return result.toUIMessageStreamResponse();
+```
+
+## Removed managed input state in `useChat`
+
+The `useChat` hook no longer manages input state internally. You must now manage input state manually.
+
+```tsx
+// ❌ Deprecated
+import { useChat } from '@ai-sdk/react';
+
+export default function Page() {
+  const {
+    input, // deprecated: manage input state manually with useState
+    handleInputChange, // deprecated: use custom onChange handler
+    handleSubmit, // deprecated: use sendMessage() instead
+  } = useChat({
+    api: '/api/chat', // deprecated: use `transport: new DefaultChatTransport({ api })` instead
+  });
+
+  return (
+    <form onSubmit={handleSubmit}>
+      <input value={input} onChange={handleInputChange} />
+      <button type="submit">Send</button>
+    </form>
+  );
+}
+
+// ✅ Correct
+import { useChat } from '@ai-sdk/react';
+import { DefaultChatTransport } from 'ai';
+import { useState } from 'react';
+
+export default function Page() {
+  const [input, setInput] = useState('');
+  const { sendMessage } = useChat({
+    transport: new DefaultChatTransport({ api: '/api/chat' }),
+  });
+
+  const handleSubmit = (e) => {
+    e.preventDefault();
+    sendMessage({ text: input });
+    setInput('');
+  };
+
+  return (
+    <form onSubmit={handleSubmit}>
+      <input value={input} onChange={(e) => setInput(e.target.value)} />
+      <button type="submit">Send</button>
+    </form>
+  );
+}
+```
+
+## `tool-invocation` → `tool-{toolName}` (typed tool parts)
+
+When rendering messages with `useChat`, use the typed tool part names (`tool-{toolName}`) instead of the generic `tool-invocation` type. This provides better type safety and access to tool-specific input/output types.
+
+> For end-to-end type-safety, see [Type-Safe Agents](type-safe-agents.md).
+
+Typed tool parts also use different property names:
+
+- `part.args` → `part.input`
+- `part.result` → `part.output`
+
+```tsx
+// ❌ Incorrect - using generic tool-invocation
+{
+  message.parts.map((part, i) => {
+    switch (part.type) {
+      case 'text':
+        return <div key={`${message.id}-${i}`}>{part.text}</div>;
+      case 'tool-invocation': // deprecated: use typed tool parts instead
+        return <pre key={`${message.id}-${i}`}>{JSON.stringify(part.toolInvocation, null, 2)}</pre>;
+    }
+  });
+}
+
+// ✅ Correct - using typed tool parts (recommended)
+{
+  message.parts.map((part) => {
+    switch (part.type) {
+      case 'text':
+        return part.text;
+      case 'tool-askForConfirmation':
+        // handle askForConfirmation tool
+        break;
+      case 'tool-getWeatherInformation':
+        // handle getWeatherInformation tool
+        break;
+    }
+  });
+}
+
+// ✅ Alternative - using isToolUIPart as a catch-all
+import { isToolUIPart } from 'ai';
+
+{
+  message.parts.map((part) => {
+    if (part.type === 'text') {
+      return part.text;
+    }
+    if (isToolUIPart(part)) {
+      // handle any tool part generically
+      return (
+        <div key={part.toolCallId}>
+          {part.toolName}: {part.state}
+        </div>
+      );
+    }
+  });
+}
+```
+
+## `useChat` state-dependent property access
+
+Tool part properties are only available in certain states. TypeScript will error if you access them without checking state first.
+
+```tsx
+// ❌ Incorrect - input may be undefined during streaming
+// TS18048: 'part.input' is possibly 'undefined'
+if (part.type === 'tool-getWeather') {
+  const location = part.input.location;
+}
+
+// ✅ Correct - check for input-available or output-available
+if (
+  part.type === 'tool-getWeather' &&
+  (part.state === 'input-available' || part.state === 'output-available')
+) {
+  const location = part.input.location;
+}
+
+// ❌ Incorrect - output is only available after execution
+// TS18048: 'part.output' is possibly 'undefined'
+if (part.type === 'tool-getWeather') {
+  const weather = part.output;
+}
+
+// ✅ Correct - check for output-available
+if (part.type === 'tool-getWeather' && part.state === 'output-available') {
+  const location = part.input.location;
+  const weather = part.output;
+}
+```
+
+## `part.toolInvocation.args` → `part.input`
+
+```tsx
+// ❌ Incorrect
+if (part.type === 'tool-invocation') {
+  // deprecated: use `part.input` on typed tool parts instead
+  const location = part.toolInvocation.args.location;
+}
+
+// ✅ Correct
+if (
+  part.type === 'tool-getWeather' &&
+  (part.state === 'input-available' || part.state === 'output-available')
+) {
+  const location = part.input.location;
+}
+```
+
+## `part.toolInvocation.result` → `part.output`
+
+```tsx
+// ❌ Incorrect
+if (part.type === 'tool-invocation') {
+  // deprecated: use `part.output` on typed tool parts instead
+  const weather = part.toolInvocation.result;
+}
+
+// ✅ Correct
+if (part.type === 'tool-getWeather' && part.state === 'output-available') {
+  const weather = part.output;
+}
+```
+
+## `part.toolInvocation.toolCallId` → `part.toolCallId`
+
+```tsx
+// ❌ Incorrect
+if (part.type === 'tool-invocation') {
+  // deprecated: use `part.toolCallId` on typed tool parts instead
+  const id = part.toolInvocation.toolCallId;
+}
+

+if (part.type === 'tool-getWeather') {
+  const id = part.toolCallId;
+}
+```
+
+## Tool invocation states renamed
+
+```tsx
+// ❌ Incorrect

+
+# AI SDK DevTools
+
+## Why Use DevTools
+
+DevTools captures all AI SDK calls (`generateText`, `streamText`, `ToolLoopAgent`) to a local JSON file. This lets you inspect LLM requests, responses, tool calls, and multi-step interactions without manually logging.
+
+## Setup
+
+Requires AI SDK 6. Install `@ai-sdk/devtools` using your project's package manager.
+
+Wrap your model with the middleware:
+
+```ts
+import { wrapLanguageModel, gateway } from 'ai';
+import { devToolsMiddleware } from '@ai-sdk/devtools';
+
+const model = wrapLanguageModel({
+  model: gateway('anthropic/claude-sonnet-4.5'),
+  middleware: devToolsMiddleware(),
+});
+```
+
+## Viewing Captured Data
+
+All runs and steps are saved to:
+
+```
+.devtools/generations.json
+```
+
+Read this file directly to inspect captured data:
+
+```bash
+cat .devtools/generations.json | jq
+```
+
+Or launch the web UI:
+
+```bash
+npx @ai-sdk/devtools
+# Open http://localhost:4983
+```
+
+## Data Structure
+
+- **Run**: A complete multi-step interaction grouped by initial prompt
+- **Step**: A single LLM call within a run (includes input, output, tool calls, token usage)

+---
+
+# Type-Safe useChat with Agents
+
+Build end-to-end type-safe agents by inferring `UIMessage` types from your agent definition for type-safe UI rendering with `useChat`.
+
+## Recommended Structure
+
+```
+lib/
+  agents/
+    my-agent.ts       # Agent definition + type export
+  tools/
+    weather-tool.ts   # Individual tool definitions
+    calculator-tool.ts
+```
+
+## Define Tools
+
+```ts
+// lib/tools/weather-tool.ts
+import { tool } from 'ai';
+import { z } from 'zod';
+
+export const weatherTool = tool({
+  description: 'Get current weather for a location',
+  inputSchema: z.object({
+    location: z.string().describe('City name'),
+  }),
+  execute: async ({ location }) => {
+    return { temperature: 72, condition: 'sunny', location };
+  },
+});
+```
+
+## Define Agent and Export Type
+
+```ts
+// lib/agents/my-agent.ts
+import { ToolLoopAgent, InferAgentUIMessage } from 'ai';
+import { weatherTool } from '../tools/weather-tool';
+import { calculatorTool } from '../tools/calculator-tool';
+
+export const myAgent = new ToolLoopAgent({
+  model: 'anthropic/claude-sonnet-4',
+  instructions: 'You are a helpful assistant.',
+  tools: {
+    weather: weatherTool,
+    calculator: calculatorTool,
+  },
+});
+
+// Infer the UIMessage type from the agent
+export type MyAgentUIMessage = InferAgentUIMessage<typeof myAgent>;
+```
+
+### With Custom Metadata
+
+```ts
+// lib/agents/my-agent.ts
+import { z } from 'zod';
+
+const metadataSchema = z.object({
+  createdAt: z.number(),
+  model: z.string().optional(),
+});
+
+type MyMetadata = z.infer<typeof metadataSchema>;
+
+export type MyAgentUIMessage = InferAgentUIMessage<typeof myAgent, MyMetadata>;
+```
+
+## Use with `useChat`
+
+```tsx
+// app/chat.tsx
+import { useChat } from '@ai-sdk/react';
+import type { MyAgentUIMessage } from '@/lib/agents/my-agent';
+
+export function Chat() {
+  const { messages } = useChat<MyAgentUIMessage>();
+
+  return (
+    <div>
+      {messages.map((message) => (
+        <Message key={message.id} message={message} />
+      ))}
+    </div>
+  );
+}
+```
+
+## Rendering Parts with Type Safety
+
+Tool parts are typed as `tool-{toolName}` based on your agent's tools:
+
+```tsx
+function Message({ message }: { message: MyAgentUIMessage }) {
+  return (
+    <div>
+      {message.parts.map((part, i) => {
+        switch (part.type) {
+          case 'text':
+            return <p key={i}>{part.text}</p>;
+
+          case 'tool-weather':
+            // part.input and part.output are fully typed
+            if (part.state === 'output-available') {
+              return (
+                <div key={i}>
+                  Weather in {part.input.location}: {part.output.temperature}F
+                </div>
+              );
+            }
+            return <div key={i}>Loading weather...</div>;
+
+          case 'tool-calculator':
+            // TypeScript knows this is the calculator tool
+            return <div key={i}>Calculating...</div>;
+
+          default:
+            return null;
+        }
+      })}
+    </div>
+  );
+}
+```
+
+The `part.type` discriminant narrows the type, giving you autocomplete and type checking for `input` and `output` based on each tool's schema.
+
+## Splitting Tool Rendering into Components
+
+When rendering many tools, you may want to split each tool into its own component. Use `UIToolInvocation<TOOL>` to derive a typed invocation from your tool and export it alongside the tool definition:
+
+```ts
+// lib/tools/weather-tool.ts
+import { tool, UIToolInvocation } from 'ai';
+import { z } from 'zod';
+
+export const weatherTool = tool({
+  description: 'Get current weather for a location',
+  inputSchema: z.object({
+    location: z.string().describe('City name'),
+  }),
+  execute: async ({ location }) => {
+    return { temperature: 72, condition: 'sunny', location };
+  },
+});
+
+// Export the invocation type for use in UI components
+export type WeatherToolInvocation = UIToolInvocation<typeof weatherTool>;
+```
+
+Then import only the type in your component:
+
+```tsx
+// components/weather-tool.tsx
+import type { WeatherToolInvocation } from '@/lib/tools/weather-tool';
+
+export function WeatherToolComponent({ invocation }: { invocation: WeatherToolInvocation }) {
+  // invocation.input and invocation.output are fully typed
+  if (invocation.state === 'output-available') {
+    return (
+      <div>
+        Weather in {invocation.input.location}: {invocation.output.temperature}F
+      </div>
+    );
+  }
+  return <div>Loading weather for {invocation.input?.location}...</div>;
+}
+```
+
+Use the component in your message renderer:
+
+```tsx
+function Message({ message }: { message: MyAgentUIMessage }) {
+  return (
+    <div>
+      {message.parts.map((part, i) => {
+        switch (part.type) {
+          case 'text':
+            return <p key={i}>{part.text}</p>;
+          case 'tool-weather':
+            return <WeatherToolComponent key={i} invocation={part} />;
+          case 'tool-calculator':
+            return <CalculatorToolComponent key={i} invocation={part} />;
+          default:
+            return null;
+        }
+      })}
+    </div>
+  );
+}
+```
+
+This approach keeps your tool rendering logic organized while maintaining full type safety, without needing to import the tool implementation into your UI components.

+description: Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
+license: Complete terms in LICENSE.txt
+---
+
+Algorithmic philosophies are computational aesthetic movements that are then expressed through code. Output .md files (philosophy), .html files (interactive viewer), and .js files (generative algorithms).
+
+This happens in two steps:
+
+1. Algorithmic Philosophy Creation (.md file)
+2. Express by creating p5.js generative art (.html + .js files)
+
+First, undertake this task:
+
+## ALGORITHMIC PHILOSOPHY CREATION
+
+To begin, create an ALGORITHMIC PHILOSOPHY (not static images or templates) that will be interpreted through:
+
+- Computational processes, emergent behavior, mathematical beauty
+- Seeded randomness, noise fields, organic systems
+- Particles, flows, fields, forces
+- Parametric variation and controlled chaos
+
+### THE CRITICAL UNDERSTANDING
+
+- What is received: Some subtle input or instructions by the user to take into account, but use as a foundation; it should not constrain creative freedom.
+- What is created: An algorithmic philosophy/generative aesthetic movement.
+- What happens next: The same version receives the philosophy and EXPRESSES IT IN CODE - creating p5.js sketches that are 90% algorithmic generation, 10% essential parameters.
+
+Consider this approach:
+
+- Write a manifesto for a generative art movement
+- The next phase involves writing the algorithm that brings it to life
+
+The philosophy must emphasize: Algorithmic expression. Emergent behavior. Computational beauty. Seeded variation.
+
+### HOW TO GENERATE AN ALGORITHMIC PHILOSOPHY
+
+**Name the movement** (1-2 words): "Organic Turbulence" / "Quantum Harmonics" / "Emergent Stillness"
+
+**Articulate the philosophy** (4-6 paragraphs - concise but complete):
+
+To capture the ALGORITHMIC essence, express how this philosophy manifests through:
+
+- Computational processes and mathematical relationships?
+- Noise functions and randomness patterns?
+- Particle behaviors and field dynamics?
+- Temporal evolution and system states?
+- Parametric variation and emergent complexity?
+
+**CRITICAL GUIDELINES:**
+
+- **Avoid redundancy**: Each algorithmic aspect should be mentioned once. Avoid repeating concepts about noise theory, particle dynamics, or mathematical principles unless adding new depth.
+- **Emphasize craftsmanship REPEATEDLY**: The philosophy MUST stress multiple times that the final algorithm should appear as though it took countless hours to develop, was refined with care, and comes from someone at the absolute top of their field. This framing is essential - repeat phrases like "meticulously crafted algorithm," "the product of deep computational expertise," "painstaking optimization," "master-level implementation."
+- **Leave creative space**: Be specific about the algorithmic direction, but concise enough that the next Claude has room to make interpretive implementation choices at an extremely high level of craftsmanship.
+
+The philosophy must guide the next version to express ideas ALGORITHMICALLY, not through static images. Beauty lives in the process, not the final frame.
+
+### PHILOSOPHY EXAMPLES
+
+**"Organic Turbulence"**
+Philosophy: Chaos constrained by natural law, order emerging from disorder.
+Algorithmic expression: Flow fields driven by layered Perlin noise. Thousands of particles following vector forces, their trails accumulating into organic density maps. Multiple noise octaves create turbulent regions and calm zones. Color emerges from velocity and density - fast particles burn bright, slow ones fade to shadow. The algorithm runs until equilibrium - a meticulously tuned balance where every parameter was refined through countless iterations by a master of computational aesthetics.
+
+**"Quantum Harmonics"**
+Philosophy: Discrete entities exhibiting wave-like interference patterns.
+Algorithmic expression: Particles initialized on a grid, each carrying a phase value that evolves through sine waves. When particles are near, their phases interfere - constructive interference creates bright nodes, destructive creates voids. Simple harmonic motion generates complex emergent mandalas. The result of painstaking frequency calibration where every ratio was carefully chosen to produce resonant beauty.
+
+**"Recursive Whispers"**
+Philosophy: Self-similarity across scales, infinite depth in finite space.
+Algorithmic expression: Branching structures that subdivide recursively. Each branch slightly randomized but constrained by golden ratios. L-systems or recursive subdivision generate tree-like forms that feel both mathematical and organic. Subtle noise perturbations break perfect symmetry. Line weights diminish with each recursion level. Every branching angle the product of deep mathematical exploration.
+
+**"Field Dynamics"**
+Philosophy: Invisible forces made visible through their effects on matter.
+Algorithmic expression: Vector fields constructed from mathematical functions or noise. Particles born at edges, flowing along field lines, dying when they reach equilibrium or boundaries. Multiple fields can attract, repel, or rotate particles. The visualization shows only the traces - ghost-like evidence of invisible forces. A computational dance meticulously choreographed through force balance.
+
+**"Stochastic Crystallization"**
+Philosophy: Random processes crystallizing into ordered structures.
+Algorithmic expression: Randomized circle packing or Voronoi tessellation. Start with random points, let them evolve through relaxation algorithms. Cells push apart until equilibrium. Color based on cell size, neighbor count, or distance from center. The organic tiling that emerges feels both random and inevitable. Every seed produces unique crystalline beauty - the mark of a master-level generative algorithm.
+
+_These are condensed examples. The actual algorithmic philosophy should be 4-6 substantial paragraphs._
+
+### ESSENTIAL PRINCIPLES
+
+- **ALGORITHMIC PHILOSOPHY**: Creating a computational worldview to be expressed through code
+- **PROCESS OVER PRODUCT**: Always emphasize that beauty emerges from the algorithm's execution - each run is unique
+- **PARAMETRIC EXPRESSION**: Ideas communicate through mathematical relationships, forces, behaviors - not static composition
+- **ARTISTIC FREEDOM**: The next Claude interprets the philosophy algorithmically - provide creative implementation room
+- **PURE GENERATIVE ART**: This is about making LIVING ALGORITHMS, not static images with randomness
+- **EXPERT CRAFTSMANSHIP**: Repeatedly emphasize the final algorithm must feel meticulously crafted, refined through countless iterations, the product of deep expertise by someone at the absolute top of their field in computational aesthetics
+
+**The algorithmic philosophy should be 4-6 paragraphs long.** Fill it with poetic computational philosophy that brings together the intended vision. Avoid repeating the same points. Output this algorithmic philosophy as a .md file.
+
+---
+
+## DEDUCING THE CONCEPTUAL SEED
+
+**CRITICAL STEP**: Before implementing the algorithm, identify the subtle conceptual thread from the original request.
+
+**THE ESSENTIAL PRINCIPLE**:
+The concept is a **subtle, niche reference embedded within the algorithm itself** - not always literal, always sophisticated. Someone familiar with the subject should feel it intuitively, while others simply experience a masterful generative composition. The algorithmic philosophy provides the computational language. The deduced concept provides the soul - the quiet conceptual DNA woven invisibly into parameters, behaviors, and emergence patterns.
+
+This is **VERY IMPORTANT**: The reference must be so refined that it enhances the work's depth without announcing itself. Think like a jazz musician quoting another song through algorithmic harmony - only those who know will catch it, but everyone appreciates the generative beauty.
+
+---
+
+## P5.JS IMPLEMENTATION
+
+With the philosophy AND conceptual framework established, express it through code. Pause to gather thoughts before proceeding. Use only the algorithmic philosophy created and the instructions below.
+
+### ⚠️ STEP 0: READ THE TEMPLATE FIRST ⚠️
+
+**CRITICAL: BEFORE writing any HTML:**
+
+1. **Read** `templates/viewer.html` using the Read tool
+2. **Study** the exact structure, styling, and Anthropic branding
+3. **Use that file as the LITERAL STARTING POINT** - not just inspiration
+4. **Keep all FIXED sections exactly as shown** (header, sidebar structure, Anthropic colors/fonts, seed controls, action buttons)
+5. **Replace only the VARIABLE sections** marked in the file's comments (algorithm, parameters, UI controls for parameters)
+
+**Avoid:**
+
+- ❌ Creating HTML from scratch
+- ❌ Inventing custom styling or color schemes
+- ❌ Using system fonts or dark themes
+- ❌ Changing the sidebar structure
+
+**Follow these practices:**
+
+- ✅ Copy the template's exact HTML structure
+- ✅ Keep Anthropic branding (Poppins/Lora fonts, light colors, gradient backdrop)
+- ✅ Maintain the sidebar layout (Seed → Parameters → Colors? → Actions)
+- ✅ Replace only the p5.js algorithm and parameter controls
+
+The template is the foundation. Build on it, don't rebuild it.
+
+---
+
+To create gallery-quality computational art that lives and breathes, use the algorithmic philosophy as the foundation.
+
+### TECHNICAL REQUIREMENTS
+
+**Seeded Randomness (Art Blocks Pattern)**:
+
+```javascript
+// ALWAYS use a seed for reproducibility
+let seed = 12345; // or hash from user input
+randomSeed(seed);
+noiseSeed(seed);
+```
+
+**Parameter Structure - FOLLOW THE PHILOSOPHY**:
+
+To establish parameters that emerge naturally from the algorithmic philosophy, consider: "What qualities of this system can be adjusted?"
+
+```javascript
+let params = {
+  seed: 12345, // Always include seed for reproducibility
+  // colors
+  // Add parameters that control YOUR algorithm:
+  // - Quantities (how many?)
+  // - Scales (how big? how fast?)
+  // - Probabilities (how likely?)
+  // - Ratios (what proportions?)
+  // - Angles (what direction?)
+  // - Thresholds (when does behavior change?)
+};
+```
+
+**To design effective parameters, focus on the properties the system needs to be tunable rather than thinking in terms of "pattern types".**
+
+**Core Algorithm - EXPRESS THE PHILOSOPHY**:
+
+**CRITICAL**: The algorithmic philosophy should dictate what to build.
+
+To express the philosophy through code, avoid thinking "which pattern should I use?" and instead think "how to express this philosophy through code?"
+
+If the philosophy is about **organic emergence**, consider using:
+
+- Elements that accumulate or grow over time
+- Random processes constrained by natural rules
+- Feedback loops and interactions
+
+If the philosophy is about **mathematical beauty**, consider using:
+
+- Geometric relationships and ratios
+- Trigonometric functions and harmonics
+- Precise calculations creating unexpected patterns
+
+If the philosophy is about **controlled chaos**, consider using:
+
+- Random variation within strict boundaries
+- Bifurcation and phase transitions
+- Order emerging from disorder
+
+**The algorithm flows from the philosophy, not from a menu of options.**
+
+To guide the implementation, let the conceptual essence inform creative and original choices. Build something that expresses the vision for this particular request.
+
+**Canvas Setup**: Standard p5.js structure:
+
+```javascript
+function setup() {
+  createCanvas(1200, 1200);
+  // Initialize your system
+}
+
+function draw() {
+  // Your generative algorithm
+  // Can be static (noLoop) or animated
+}
+```
+
+### CRAFTSMANSHIP REQUIREMENTS
+
+**CRITICAL**: To achieve mastery, create algorithms that feel like they emerged through countless iterations by a master generative artist. Tune every parameter carefully. Ensure every pattern emerges with purpose. This is NOT random noise - this is CONTROLLED CHAOS refined through deep expertise.
+
+- **Balance**: Complexity without visual noise, order without rigidity
+- **Color Harmony**: Thoughtful palettes, not random RGB values
+- **Composition**: Even in randomness, maintain visual hierarchy and flow
+- **Performance**: Smooth execution, optimized for real-time if animated
+- **Reproducibility**: Same seed ALWAYS produces identical output
+
+### OUTPUT FORMAT
+
+Output:
+
+1. **Algorithmic Philosophy** - As markdown or text explaining the generative aesthetic
+2. **Single HTML Artifact** - Self-contained interactive generative art built from `templates/viewer.html` (see STEP 0 and next section)
+
+The HTML artifact contains everything: p5.js (from CDN), the algorithm, parameter controls, and UI - all in one file that works immediately in claude.ai artifacts or any browser. Start from the template file, not from scratch.
+
+---
+
+## INTERACTIVE ARTIFACT CREATION
+
+**REMINDER: `templates/viewer.html` should have already been read (see STEP 0). Use that file as the starting point.**
+
+To allow exploration of the generative art, create a single, self-contained HTML artifact. Ensure this artifact works immediately in claude.ai or any browser - no setup required. Embed everything inline.
+
+### CRITICAL: WHAT'S FIXED VS VARIABLE
+
+The `templates/viewer.html` file is the foundation. It contains the exact structure and styling needed.
+
+**FIXED (always include exactly as shown):**
+
+- Layout structure (header, sidebar, main canvas area)
+- Anthropic branding (UI colors, fonts, gradients)
+- Seed section in sidebar:
+  - Seed display
+  - Previous/Next buttons
+  - Random button
+  - Jump to seed input + Go button
+- Actions section in sidebar:
+  - Regenerate button
+  - Reset button
+
+**VARIABLE (customize for each artwork):**
+
+- The entire p5.js algorithm (setup/draw/classes)
+- The parameters object (define what the art needs)
+- The Parameters section in sidebar:
+  - Number of parameter controls
+  - Parameter names
+  - Min/max/step values for sliders
+  - Control types (sliders, inputs, etc.)
+- Colors section (optional):
+  - Some art needs color pickers
+  - Some art might use fixed colors
+  - Some art might be monochrome (no color controls needed)
+  - Decide based on the art's needs
+
+**Every artwork should have unique parameters and algorithm!** The fixed parts provide consistent UX - everything else expresses the unique vision.
+
+### REQUIRED FEATURES
+
+**1. Parameter Controls**
+
+- Sliders for numeric parameters (particle count, noise scale, speed, etc.)
+- Color pickers for palette colors
+- Real-time updates when parameters change
+- Reset button to restore defaults
+
+**2. Seed Navigation**
+
+- Display current seed number
+- "Previous" and "Next" buttons to cycle through seeds
+- "Random" button for random seed
+- Input field to jump to specific seed
+- Generate 100 variations when requested (seeds 1-100)
+
+**3. Single Artifact Structure**
+
+```html
+<!DOCTYPE html>
+<html>
+  <head>
+    <!-- p5.js from CDN - always available -->
+    <script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.7.0/p5.min.js"></script>
+    <style>
+      /* All styling inline - clean, minimal */
+      /* Canvas on top, controls below */
+    </style>
+  </head>
+  <body>
+    <div id="canvas-container"></div>
+    <div id="controls">
+      <!-- All parameter controls -->
+    </div>
+    <script>
+      // ALL p5.js code inline here
+      // Parameter objects, classes, functions
+      // setup() and draw()
+      // UI handlers
+      // Everything self-contained
+    </script>
+  </body>
+</html>
+```
+
+**CRITICAL**: This is a single artifact. No external files, no imports (except p5.js CDN). Everything inline.
+
+**4. Implementation Details - BUILD THE SIDEBAR**
+
+The sidebar structure:
+
+**1. Seed (FIXED)** - Always include exactly as shown:
+
+- Seed display
+- Prev/Next/Random/Jump buttons
+
+**2. Parameters (VARIABLE)** - Create controls for the art:
+
+```html
+<div class="control-group">
+  <label>Parameter Name</label>
+  <input
+    type="range"
+    id="param"
+    min="..."
+    max="..."
+    step="..."
+    value="..."
+    oninput="updateParam('param', this.value)"
+  />
+  <span class="value-display" id="param-value">...</span>
+</div>
+```
+
+Add as many control-group divs as there are parameters.
+
+**3. Colors (OPTIONAL/VARIABLE)** - Include if the art needs adjustable colors:
+
+- Add color pickers if users should control palette
+- Skip this section if the art uses fixed colors
+- Skip if the art is monochrome
+
+**4. Actions (FIXED)** - Always include exactly as shown:
+
+- Regenerate button
+- Reset button
+- Download PNG button
+
+**Requirements**:
+
+- Seed controls must work (prev/next/random/jump/display)
+- All parameters must have UI controls
+- Regenerate, Reset, Download buttons must work
+- Keep Anthropic branding (UI styling, not art colors)
+
+### USING THE ARTIFACT
+
+The HTML artifact works immediately:
+
+1. **In claude.ai**: Displayed as an interactive artifact - runs instantly
+2. **As a file**: Save and open in any browser - no server needed
+3. **Sharing**: Send the HTML file - it's completely self-contained
+
+---
+
+## VARIATIONS & EXPLORATION
+
+The artifact includes seed navigation by default (prev/next/random buttons), allowing users to explore variations without creating multiple files. If the user wants specific variations highlighted:
+
+- Include seed presets (buttons for "Variation 1: Seed 42", "Variation 2: Seed 127", etc.)
+- Add a "Gallery Mode" that shows thumbnails of multiple seeds side-by-side
+- All within the same single artifact
+
+This is like creating a series of prints from the same plate - the algorithm is consistent, but each seed reveals different facets of its potential. The interactive nature means users discover their own favorites by exploring the seed space.
+
+---
+
+## THE CREATIVE PROCESS
+
+**User request** → **Algorithmic philosophy** → **Implementation**
+
+Each request is unique. The process involves:
+
+1. **Interpret the user's intent** - What aesthetic is being sought?
+2. **Create an algorithmic philosophy** (4-6 paragraphs) describing the computational approach
+3. **Implement it in code** - Build the algorithm that expresses this philosophy
+4. **Design appropriate parameters** - What should be tunable?
+5. **Build matching UI controls** - Sliders/inputs for those parameters
+
+**The constants**:
+
+- Anthropic branding (colors, fonts, layout)
+- Seed navigation (always present)
+- Self-contained HTML artifact
+
+**Everything else is variable**:
+
+- The algorithm itself
+- The parameters
+- The UI controls
+- The visual outcome
+
+To achieve the best results, trust creativity and let the philosophy guide the implementation.
+
+---
+
+## RESOURCES
+
+This skill includes helpful templates and documentation:
+
+- **templates/viewer.html**: REQUIRED STARTING POINT for all HTML artifacts.
+  - This is the foundation - contains the exact structure and Anthropic branding
+  - **Keep unchanged**: Layout structure, sidebar organization, Anthropic colors/fonts, seed controls, action buttons
+  - **Replace**: The p5.js algorithm, parameter definitions, and UI controls in Parameters section
+  - The extensive comments in the file mark exactly what to keep vs replace
+
+- **templates/generator_template.js**: Reference for p5.js best practices and code structure principles.
+  - Shows how to organize parameters, use seeded randomness, structure classes
+  - NOT a pattern menu - use these principles to build unique algorithms
+  - Embed algorithms inline in the HTML artifact (don't create separate .js files)
+
+**Critical reminder**:
+
+- The **template is the STARTING POINT**, not inspiration
+- The **algorithm is where to create** something unique
+- Don't copy the flow field example - build what the philosophy demands
+- But DO keep the exact UI structure and Anthropic branding from the template

+ * ═══════════════════════════════════════════════════════════════════════════
+ *
+ * This file shows STRUCTURE and PRINCIPLES for p5.js generative art.
+ * It does NOT prescribe what art you should create.
+ *
+ * Your algorithmic philosophy should guide what you build.
+ * These are just best practices for how to structure your code.
+ *
+ * ═══════════════════════════════════════════════════════════════════════════
+ */
+
+// ============================================================================
+// 1. PARAMETER ORGANIZATION
+// ============================================================================
+// Keep all tunable parameters in one object
+// This makes it easy to:
+// - Connect to UI controls
+// - Reset to defaults
+// - Serialize/save configurations
+
+let params = {
+  // Define parameters that match YOUR algorithm
+  // Examples (customize for your art):
+  // - Counts: how many elements (particles, circles, branches, etc.)
+  // - Scales: size, speed, spacing
+  // - Probabilities: likelihood of events
+  // - Angles: rotation, direction
+  // - Colors: palette arrays
+
+  seed: 12345,
+  // define colorPalette as an array -- choose whatever colors you'd like ['#d97757', '#6a9bcc', '#788c5d', '#b0aea5']
+  // Add YOUR parameters here based on your algorithm
+};
+
+// ============================================================================
+// 2. SEEDED RANDOMNESS (Critical for reproducibility)
+// ============================================================================
+// ALWAYS use seeded random for Art Blocks-style reproducible output
+
+function initializeSeed(seed) {
+  randomSeed(seed);
+  noiseSeed(seed);
+  // Now all random() and noise() calls will be deterministic
+}
+
+// ============================================================================
+// 3. P5.JS LIFECYCLE
+// ============================================================================
+
+function setup() {
+  createCanvas(800, 800);
+
+  // Initialize seed first
+  initializeSeed(params.seed);
+
+  // Set up your generative system
+  // This is where you initialize:
+  // - Arrays of objects
+  // - Grid structures
+  // - Initial positions
+  // - Starting states
+
+  // For static art: call noLoop() at the end of setup
+  // For animated art: let draw() keep running
+}
+
+function draw() {
+  // Option 1: Static generation (runs once, then stops)
+  // - Generate everything in setup()
+  // - Call noLoop() in setup()
+  // - draw() doesn't do much or can be empty
+  // Option 2: Animated generation (continuous)
+  // - Update your system each frame
+  // - Common patterns: particle movement, growth, evolution
+  // - Can optionally call noLoop() after N frames
+  // Option 3: User-triggered regeneration
+  // - Use noLoop() by default
+  // - Call redraw() when parameters change
+}
+
+// ============================================================================
+// 4. CLASS STRUCTURE (When you need objects)
+// ============================================================================
+// Use classes when your algorithm involves multiple entities
+// Examples: particles, agents, cells, nodes, etc.
+
+class Entity {
+  constructor() {
+    // Initialize entity properties
+    // Use random() here - it will be seeded
+  }
+
+  update() {
+    // Update entity state
+    // This might involve:
+    // - Physics calculations
+    // - Behavioral rules
+    // - Interactions with neighbors
+  }
+
+  display() {
+    // Render the entity
+    // Keep rendering logic separate from update logic
+  }
+}
+
+// ============================================================================
+// 5. PERFORMANCE CONSIDERATIONS
+// ============================================================================
+
+// For large numbers of elements:
+// - Pre-calculate what you can
+// - Use simple collision detection (spatial hashing if needed)
+// - Limit expensive operations (sqrt, trig) when possible
+// - Consider using p5 vectors efficiently
+
+// For smooth animation:
+// - Aim for 60fps
+// - Profile if things are slow
+// - Consider reducing particle counts or simplifying calculations
+
+// ============================================================================
+// 6. UTILITY FUNCTIONS
+// ============================================================================
+
+// Color utilities
+function hexToRgb(hex) {
+  const result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex);
+  return result
+    ? {
+        r: parseInt(result[1], 16),
+        g: parseInt(result[2], 16),
+        b: parseInt(result[3], 16),
+      }
+    : null;
+}
+
+function colorFromPalette(index) {
+  return params.colorPalette[index % params.colorPalette.length];
+}
+
+// Mapping and easing
+function mapRange(value, inMin, inMax, outMin, outMax) {
+  return outMin + (outMax - outMin) * ((value - inMin) / (inMax - inMin));
+}
+
+function easeInOutCubic(t) {
+  return t < 0.5 ? 4 * t * t * t : 1 - Math.pow(-2 * t + 2, 3) / 2;
+}
+
+// Constrain to bounds
+function wrapAround(value, max) {
+  if (value < 0) return max;
+  if (value > max) return 0;
+  return value;
+}
+
+// ============================================================================
+// 7. PARAMETER UPDATES (Connect to UI)
+// ============================================================================
+
+function updateParameter(paramName, value) {
+  params[paramName] = value;
+  // Decide if you need to regenerate or just update
+  // Some params can update in real-time, others need full regeneration
+}
+
+function regenerate() {
+  // Reinitialize your generative system
+  // Useful when parameters change significantly
+  initializeSeed(params.seed);
+  // Then regenerate your system
+}
+
+// ============================================================================
+// 8. COMMON P5.JS PATTERNS
+// ============================================================================
+
+// Drawing with transparency for trails/fading
+function fadeBackground(opacity) {
+  fill(250, 249, 245, opacity); // Anthropic light with alpha
+  noStroke();
+  rect(0, 0, width, height);
+}
+
+// Using noise for organic variation
+function getNoiseValue(x, y, scale = 0.01) {
+  return noise(x * scale, y * scale);
+}
+
+// Creating vectors from angles
+function vectorFromAngle(angle, magnitude = 1) {
+  return createVector(cos(angle), sin(angle)).mult(magnitude);
+}
+
+// ============================================================================
+// 9. EXPORT FUNCTIONS
+// ============================================================================
+
+function exportImage() {
+  saveCanvas('generative-art-' + params.seed, 'png');
+}
+
+// ============================================================================
+// REMEMBER
+// ============================================================================
+//
+// These are TOOLS and PRINCIPLES, not a recipe.
+// Your algorithmic philosophy should guide WHAT you create.
+// This structure helps you create it WELL.
+//
+// Focus on:
+// - Clean, readable code
+// - Parameterized for exploration
+// - Seeded for reproducibility
+// - Performant execution
+//
+// The art itself is entirely up to you!
+//
+// ============================================================================

+    THIS IS A TEMPLATE THAT SHOULD BE USED EVERY TIME AND MODIFIED.
+    WHAT TO KEEP:
+    ✓ Overall structure (header, sidebar, main content)
+    ✓ Anthropic branding (colors, fonts, layout)
+    ✓ Seed navigation section (always include this)
+    ✓ Self-contained artifact (everything inline)
+
+    WHAT TO CREATIVELY EDIT:
+    ✗ The p5.js algorithm (implement YOUR vision)
+    ✗ The parameters (define what YOUR art needs)
+    ✗ The UI controls (match YOUR parameters)
+
+    Let your philosophy guide the implementation.
+    The world is your oyster - be creative!

+
+# Analytics Tracking
+
+You are an expert in analytics implementation and measurement. Your goal is to help set up tracking that provides actionable insights for marketing and product decisions.
+
+## Initial Assessment
+
+**Check for product marketing context first:**
+If `.mosaic/product-marketing-context.md` exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
+
+Before implementing tracking, understand:
+
+1. **Business Context** - What decisions will this data inform? What are key conversions?
+2. **Current State** - What tracking exists? What tools are in use?
+3. **Technical Context** - What's the tech stack? Any privacy/compliance requirements?
+
+---
+
+## Core Principles
+
+### 1. Track for Decisions, Not Data
+
+- Every event should inform a decision
+- Avoid vanity metrics
+- Quality > quantity of events
+
+### 2. Start with the Questions
+
+- What do you need to know?
+- What actions will you take based on this data?
+- Work backwards to what you need to track
+
+### 3. Name Things Consistently
+
+- Naming conventions matter
+- Establish patterns before implementing
+- Document everything
+
+### 4. Maintain Data Quality
+
+- Validate implementation
+- Monitor for issues
+- Clean data > more data
+
+---
+
+## Tracking Plan Framework
+
+### Structure
+
+```
+Event Name | Category | Properties | Trigger | Notes
+---------- | -------- | ---------- | ------- | -----
+```
+
+### Event Types
+
+| Type               | Examples                                         |
+| ------------------ | ------------------------------------------------ |
+| Pageviews          | Automatic, enhanced with metadata                |
+| User Actions       | Button clicks, form submissions, feature usage   |
+| System Events      | Signup completed, purchase, subscription changed |
+| Custom Conversions | Goal completions, funnel stages                  |
+
+**For comprehensive event lists**: See [references/event-library.md](references/event-library.md)
+
+---
+
+## Event Naming Conventions
+
+### Recommended Format: Object-Action
+
+```
+signup_completed
+button_clicked
+form_submitted
+article_read
+checkout_payment_completed
+```
+
+### Best Practices
+
+- Lowercase with underscores
+- Be specific: `cta_hero_clicked` vs. `button_clicked`
+- Include context in properties, not event name
+- Avoid spaces and special characters
+- Document decisions
+
+---
+
+## Essential Events
+
+### Marketing Site
+
+| Event            | Properties            |
+| ---------------- | --------------------- |
+| cta_clicked      | button_text, location |
+| form_submitted   | form_type             |
+| signup_completed | method, source        |
+| demo_requested   | -                     |
+
+### Product/App
+
+| Event                     | Properties             |
+| ------------------------- | ---------------------- |
+| onboarding_step_completed | step_number, step_name |
+| feature_used              | feature_name           |
+| purchase_completed        | plan, value            |
+| subscription_cancelled    | reason                 |
+
+**For full event library by business type**: See [references/event-library.md](references/event-library.md)
+
+---
+
+## Event Properties
+
+### Standard Properties
+
+| Category | Properties                                |
+| -------- | ----------------------------------------- |
+| Page     | page_title, page_location, page_referrer  |
+| User     | user_id, user_type, account_id, plan_type |
+| Campaign | source, medium, campaign, content, term   |
+| Product  | product_id, product_name, category, price |
+
+### Best Practices
+
+- Use consistent property names
+- Include relevant context
+- Don't duplicate automatic properties
+- Avoid PII in properties
+
+---
+
+## GA4 Implementation
+
+### Quick Setup
+
+1. Create GA4 property and data stream
+2. Install gtag.js or GTM
+3. Enable enhanced measurement
+4. Configure custom events
+5. Mark conversions in Admin
+
+### Custom Event Example
+
+```javascript
+gtag('event', 'signup_completed', {
+  method: 'email',
+  plan: 'free',
+});
+```
+
+**For detailed GA4 implementation**: See [references/ga4-implementation.md](references/ga4-implementation.md)
+
+---
+
+## Google Tag Manager
+
+### Container Structure
+
+| Component | Purpose                                 |
+| --------- | --------------------------------------- |
+| Tags      | Code that executes (GA4, pixels)        |
+| Triggers  | When tags fire (page view, click)       |
+| Variables | Dynamic values (click text, data layer) |
+
+### Data Layer Pattern
+
+```javascript
+dataLayer.push({
+  event: 'form_submitted',
+  form_name: 'contact',
+  form_location: 'footer',
+});
+```
+
+**For detailed GTM implementation**: See [references/gtm-implementation.md](references/gtm-implementation.md)
+
+---
+
+## UTM Parameter Strategy
+
+### Standard Parameters
+
+| Parameter    | Purpose                | Example            |
+| ------------ | ---------------------- | ------------------ |
+| utm_source   | Traffic source         | google, newsletter |
+| utm_medium   | Marketing medium       | cpc, email, social |
+| utm_campaign | Campaign name          | spring_sale        |
+| utm_content  | Differentiate versions | hero_cta           |
+| utm_term     | Paid search keywords   | running+shoes      |
+
+### Naming Conventions
+
+- Lowercase everything
+- Use underscores or hyphens consistently
+- Be specific but concise: `blog_footer_cta`, not `cta1`
+- Document all UTMs in a spreadsheet
+
+---
+
+## Debugging and Validation
+
+### Testing Tools
+
+| Tool               | Use For                            |
+| ------------------ | ---------------------------------- |
+| GA4 DebugView      | Real-time event monitoring         |
+| GTM Preview Mode   | Test triggers before publish       |
+| Browser Extensions | Tag Assistant, dataLayer Inspector |
+
+### Validation Checklist
+
+- [ ] Events firing on correct triggers
+- [ ] Property values populating correctly
+- [ ] No duplicate events
+- [ ] Works across browsers and mobile
+- [ ] Conversions recorded correctly
+- [ ] No PII leaking
+
+### Common Issues
+
+| Issue             | Check                                     |
+| ----------------- | ----------------------------------------- |
+| Events not firing | Trigger config, GTM loaded                |
+| Wrong values      | Variable path, data layer structure       |
+| Duplicate events  | Multiple containers, trigger firing twice |
+
+---
+
+## Privacy and Compliance
+
+### Considerations
+
+- Cookie consent required in EU/UK/CA
+- No PII in analytics properties
+- Data retention settings
+- User deletion capabilities
+
+### Implementation
+
+- Use consent mode (wait for consent)
+- IP anonymization
+- Only collect what you need
+- Integrate with consent management platform
+
+---

+### gtag.js Implementation
+
+```javascript
+// Basic event
+gtag('event', 'signup_completed', {
+  method: 'email',
+  plan: 'free',
+});
+
+// Event with value
+gtag('event', 'purchase', {
+  transaction_id: 'T12345',
+  value: 99.99,
+  currency: 'USD',
+  items: [
+    {
+      item_id: 'SKU123',
+      item_name: 'Product Name',

+});
+
+// User ID (for logged-in users)
+gtag('config', 'GA_MEASUREMENT_ID', {
+  user_id: 'USER_ID',
+});
+```
+
+### Google Tag Manager (dataLayer)
+
+```javascript
+// Custom event
+dataLayer.push({
+  event: 'signup_completed',
+  method: 'email',
+  plan: 'free',
+});
+
+// Set user properties
+dataLayer.push({
+  user_id: '12345',
+  user_type: 'premium',
+});
+
+// E-commerce purchase
+dataLayer.push({
+  event: 'purchase',
+  ecommerce: {
+    transaction_id: 'T12345',
+    value: 99.99,
+    currency: 'USD',
+    items: [
+      {
+        item_id: 'SKU123',
+        item_name: 'Product Name',
+        price: 99.99,
+        quantity: 1,
+      },
+    ],
+  },
+});
+
+// Clear ecommerce before sending (best practice)
+dataLayer.push({ ecommerce: null });
+dataLayer.push({
+  event: 'view_item',
+  ecommerce: {
+    // ...
+  },
+});
+```
+
+---
+
+## Conversions Setup
+
+### Creating Conversions
+
+1. **Collect the event** - Ensure event is firing in GA4
+2. **Mark as conversion** - Admin > Events > Mark as conversion
+3. **Set counting method**:
+   - Once per session (leads, signups)
+   - Every event (purchases)
+4. **Import to Google Ads** - For conversion-optimized bidding
+
+### Conversion Values
+
+```javascript
+// Event with conversion value
+gtag('event', 'purchase', {
+  value: 99.99,
+  currency: 'USD',
+});
+```
+
+Or set default value in GA4 Admin when marking conversion.

+3. Choose scope:
+   - **Event**: Per event (content_type)
+   - **User**: Per user (account_type)
+   - **Item**: Per product (product_category)
+4. Enter parameter name (must match event parameter)
+
+### Examples
+
+| Dimension        | Scope | Parameter     | Description         |
+| ---------------- | ----- | ------------- | ------------------- |
+| User Type        | User  | user_type     | Free, trial, paid   |
+| Content Author   | Event | author        | Blog post author    |
+| Product Category | Item  | item_category | E-commerce category |

+dataLayer.push({
+  pageType: 'product',
+  contentGroup: 'products',
+  user: {
+    loggedIn: true,
+    userId: '12345',
+    userType: 'premium',
+  },
+});
+```
+
+### Form Submission
+
+```javascript
+document.querySelector('#contact-form').addEventListener('submit', function () {
+  dataLayer.push({
+    event: 'form_submitted',

+    formLocation: 'footer',
+  });
+});
+```
+
+### Button Click
+
+```javascript
+document.querySelector('.cta-button').addEventListener('click', function () {
+  dataLayer.push({
+    event: 'cta_clicked',
+    ctaText: this.innerText,
+    ctaLocation: 'hero',
+  });
+});
+```
+
+### E-commerce Events
+
+```javascript
+// Product view
+dataLayer.push({ ecommerce: null }); // Clear previous
+dataLayer.push({
+  event: 'view_item',
+  ecommerce: {
+    items: [

+  event: 'add_to_cart',
+  ecommerce: {
+    items: [
+      {
+        item_id: 'SKU123',

+
+- Measurement ID: G-XXXXXXXX
+- Send page view: Checked (for pageviews)
+- User Properties: Add any user-level dimensions
+
+**Trigger:** All Pages
+
+### GA4 Event Tag
+
+**Tag Type:** Google Analytics: GA4 Event
+
+**Settings:**
+
+- Configuration Tag: Select your config tag
+- Event Name: {{DL - event_name}} or hardcode
+- Event Parameters: Add parameters from dataLayer
+
+**Trigger:** Custom Event with event name match
+
+### Facebook Pixel - Base
+
+**Tag Type:** Custom HTML
+
+```html
+<script>
+  !(function (f, b, e, v, n, t, s) {
+    if (f.fbq) return;
+    n = f.fbq = function () {
+      n.callMethod ? n.callMethod.apply(n, arguments) : n.queue.push(arguments);
+    };
+    if (!f._fbq) f._fbq = n;
+    n.push = n;
+    n.loaded = !0;
+    n.version = '2.0';
+    n.queue = [];
+    t = b.createElement(e);
+    t.async = !0;
+    t.src = v;
+    s = b.getElementsByTagName(e)[0];
+    s.parentNode.insertBefore(t, s);
+  })(window, document, 'script', 'https://connect.facebook.net/en_US/fbevents.js');
+  fbq('init', 'YOUR_PIXEL_ID');
+  fbq('track', 'PageView');
+</script>
+```
+
+**Trigger:** All Pages
+
+### Facebook Pixel - Event
+
+**Tag Type:** Custom HTML
+
+```html
+<script>
+  fbq('track', 'Lead', {
+    content_name: '{{DL - form_name}}',
+  });
+</script>
+```
+
+**Trigger:** Custom Event - form_submitted
+
+---
+
+## Preview and Debug
+
+### Preview Mode
+
+1. Click "Preview" in GTM
+2. Enter site URL
+3. GTM debug panel opens at bottom
+
+**What to check:**
+
+- Tags fired on this event
+- Tags not fired (and why)
+- Variables and their values
+- Data layer contents
+
+### Debug Tips
+
+**Tag not firing:**
+
+- Check trigger conditions
+- Verify data layer push
+- Check tag sequencing
+
+**Wrong variable value:**
+
+- Check data layer structure
+- Verify variable path (nested objects)
+- Check timing (data may not exist yet)
+
+**Multiple firings:**
+
+- Check trigger uniqueness
+- Look for duplicate tags
+- Check tag firing options
+
+---
+
+## Workspaces and Versioning
+
+### Workspaces
+
+Use workspaces for team collaboration:
+
+- Default workspace for production
+- Separate workspaces for large changes
+- Merge when ready
+
+### Version Management
+
+**Best practices:**
+
+- Name every version descriptively
+- Add notes explaining changes
+- Review changes before publish
+- Keep production version noted
+
+**Version notes example:**
+
+```
+v15: Added purchase conversion tracking
+- New tag: GA4 - Event - Purchase
+- New trigger: Custom Event - purchase
+- New variables: DL - transaction_id, DL - value
+- Tested: Chrome, Safari, Mobile
+```
+
+---
+
+## Consent Management
+
+### Consent Mode Integration
+
+```javascript
+// Default state (before consent)
+gtag('consent', 'default', {
+  analytics_storage: 'denied',
+  ad_storage: 'denied',
+});
+
+// Update on consent
+function grantConsent() {
+  gtag('consent', 'update', {
+    analytics_storage: 'granted',
+    ad_storage: 'granted',
+  });
+}
+```
+
+### GTM Consent Overview
+
+1. Enable Consent Overview in Admin
+2. Configure consent for each tag
+3. Tags respect consent state automatically
+
+---
+
+## Advanced Patterns
+
+### Tag Sequencing
+
+**Setup tags to fire in order:**
+Tag Configuration > Advanced Settings > Tag Sequencing
+
+**Use cases:**
+
+- Config tag before event tags
+- Pixel initialization before tracking
+- Cleanup after conversion
+
+### Exception Handling
+
+**Trigger exceptions** - Prevent tag from firing:
+
+- Exclude certain pages
+- Exclude internal traffic
+- Exclude during testing
+
+### Custom JavaScript Variables
+
+```javascript
+// Get URL parameter
+function() {
+  var params = new URLSearchParams(window.location.search);
+  return params.get('campaign') || '(not set)';
+}
+
+// Get cookie value
+function() {
+  var match = document.cookie.match('(^|;) ?user_id=([^;]*)(;|$)');
+  return match ? match[2] : null;
+}
+
+// Get data from page
+function() {
+  var el = document.querySelector('.product-price');
+  return el ? parseFloat(el.textContent.replace('$', '')) : 0;
+}
+```

+description: Anthony Fu's opinionated tooling and conventions for JavaScript/TypeScript projects. Use when setting up new projects, configuring ESLint/Prettier alternatives, monorepos, library publishing, or when the user mentions Anthony Fu's preferences.
+metadata:
+  author: Anthony Fu
+  version: '2026.02.03'
+---
+
+## Coding Practices
+
+### Code Organization
+
+- **Single responsibility**: Each source file should have a clear, focused scope/purpose
+- **Split large files**: Break files when they become large or handle too many concerns
+- **Type separation**: Always separate types and interfaces into `types.ts` or `types/*.ts`
+- **Constants extraction**: Move constants to a dedicated `constants.ts` file
+
+### Runtime Environment
+
+- **Prefer isomorphic code**: Write runtime-agnostic code that works in Node, browser, and workers whenever possible
+- **Clear runtime indicators**: When code is environment-specific, add a comment at the top of the file:
+
+```ts
+// @env node
+// @env browser
+```
+
+### TypeScript
+
+- **Explicit return types**: Declare return types explicitly when possible
+- **Avoid complex inline types**: Extract complex types into dedicated `type` or `interface` declarations
+
+### Comments
+
+- **Avoid unnecessary comments**: Code should be self-explanatory
+- **Explain "why" not "how"**: Comments should describe the reasoning or intent, not what the code does
+
+### Testing (Vitest)
+
+- Test files: `foo.ts` → `foo.test.ts` (same directory)
+- Use `describe`/`it` API (not `test`)
+- Use `toMatchSnapshot` for complex outputs
+- Use `toMatchFileSnapshot` with explicit path for language-specific snapshots
+
+---
+
+## Tooling Choices
+
+### @antfu/ni Commands
+
+| Command                    | Description                                |
+| -------------------------- | ------------------------------------------ |
+| `ni`                       | Install dependencies                       |
+| `ni <pkg>` / `ni -D <pkg>` | Add dependency / dev dependency            |
+| `nr <script>`              | Run script                                 |
+| `nu`                       | Upgrade dependencies                       |
+| `nun <pkg>`                | Uninstall dependency                       |
+| `nci`                      | Clean install (`pnpm i --frozen-lockfile`) |
+| `nlx <pkg>`                | Execute package (`npx`)                    |
+
+### TypeScript Config
+
+```json
+{
+  "compilerOptions": {
+    "target": "ESNext",
+    "module": "ESNext",
+    "moduleResolution": "bundler",
+    "strict": true,
+    "esModuleInterop": true,
+    "skipLibCheck": true,
+    "resolveJsonModule": true,
+    "isolatedModules": true,
+    "noEmit": true
+  }
+}
+```
+
+### ESLint Setup
+
+```js
+// eslint.config.mjs
+import antfu from '@antfu/eslint-config';
+
+export default antfu();
+```
+
+When completing tasks, run `pnpm run lint --fix` to format the code and fix coding style.
+
+For detailed configuration options: [antfu-eslint-config](references/antfu-eslint-config.md)
+
+### Git Hooks
+
+```json
+{
+  "simple-git-hooks": {
+    "pre-commit": "pnpm i --frozen-lockfile --ignore-scripts --offline && npx lint-staged"
+  },
+  "lint-staged": { "*": "eslint --fix" },
+  "scripts": {
+    "prepare": "npx simple-git-hooks"
+  }
+}
+```
+
+### pnpm Catalogs
+
+Use named catalogs in `pnpm-workspace.yaml` for version management:
+
+| Catalog    | Purpose                              |
+| ---------- | ------------------------------------ |
+| `prod`     | Production dependencies              |
+| `inlined`  | Bundler-inlined dependencies         |
+| `dev`      | Dev tools (linter, bundler, testing) |
+| `frontend` | Frontend libraries                   |
+
+Avoid the default catalog. Catalog names can be adjusted per project needs.

+description: Configuring @antfu/eslint-config for framework support, formatters, and rule overrides. Use when adding React/Vue/Svelte/Astro support, customizing rules, or setting up VS Code integration.
+---
+
+# @antfu/eslint-config
+
+Handles both linting and formatting (no Prettier needed). Auto-detects TypeScript and Vue.
+
+**Style**: Single quotes, no semicolons, sorted imports, dangling commas.
+
+## Configuration Options
+
+```js
+import antfu from '@antfu/eslint-config';
+
+export default antfu({
+  // Project type: 'lib' for libraries, 'app' (default) for applications
+  type: 'lib',
+
+  // Global ignores (extends defaults, doesn't override)
+  ignores: ['**/fixtures', '**/dist'],
+
+  // Stylistic options
+  stylistic: {
+    indent: 2, // 2, 4, or 'tab'
+    quotes: 'single', // or 'double'
+  },
+
+  // Framework support (auto-detected, but can be explicit)
+  typescript: true,
+  vue: true,
+
+  // Disable specific language support
+  jsonc: false,
+  yaml: false,
+});
+```
+
+## Framework Support
+
+### Vue
+
+Vue accessibility:
+
+```js
+export default antfu({
+  vue: {
+    a11y: true,
+  },
+});
+// Requires: pnpm add -D eslint-plugin-vuejs-accessibility
+```
+
+### React
+
+```js
+export default antfu({
+  react: true,
+});
+// Requires: pnpm add -D @eslint-react/eslint-plugin eslint-plugin-react-hooks eslint-plugin-react-refresh
+```
+
+### Next.js
+
+```js
+export default antfu({
+  nextjs: true,
+});
+// Requires: pnpm add -D @next/eslint-plugin-next
+```
+
+### Svelte
+
+```js
+export default antfu({
+  svelte: true,
+});
+// Requires: pnpm add -D eslint-plugin-svelte
+```
+
+### Astro
+
+```js
+export default antfu({
+  astro: true,
+});
+// Requires: pnpm add -D eslint-plugin-astro
+```
+
+### Solid
+
+```js
+export default antfu({
+  solid: true,
+});
+// Requires: pnpm add -D eslint-plugin-solid
+```
+
+### UnoCSS
+
+```js
+export default antfu({
+  unocss: true,
+});
+// Requires: pnpm add -D @unocss/eslint-plugin
+```
+
+## Formatters (CSS, HTML, Markdown)
+
+For files ESLint doesn't handle natively:
+
+```js
+export default antfu({
+  formatters: {
+    css: true, // Format CSS, LESS, SCSS (uses Prettier)
+    html: true, // Format HTML (uses Prettier)
+    markdown: 'prettier', // or 'dprint'
+  },
+});
+// Requires: pnpm add -D eslint-plugin-format
+```
+
+## Rule Overrides
+
+### Global overrides
+
+```js
+export default antfu(
+  {
+    // First argument: antfu config options
+  },
+  // Additional arguments: ESLint flat configs
+  {
+    rules: {
+      'style/semi': ['error', 'never'],
+    },
+  },
+);
+```
+
+### Per-integration overrides
+
+```js
+export default antfu({
+  vue: {
+    overrides: {
+      'vue/operator-linebreak': ['error', 'before'],
+    },
+  },
+  typescript: {
+    overrides: {
+      'ts/consistent-type-definitions': ['error', 'interface'],
+    },
+  },
+});
+```
+
+### File-specific overrides
+
+```js
+export default antfu(
+  { vue: true, typescript: true },
+  {
+    files: ['**/*.vue'],
+    rules: {
+      'vue/operator-linebreak': ['error', 'before'],
+    },
+  },
+);
+```
+
+## Plugin Prefix Renaming
+
+The config renames plugin prefixes for consistency:
+
+| New Prefix | Original               |
+| ---------- | ---------------------- |
+| `ts/*`     | `@typescript-eslint/*` |
+| `style/*`  | `@stylistic/*`         |
+| `import/*` | `import-lite/*`        |
+| `node/*`   | `n/*`                  |
+| `yaml/*`   | `yml/*`                |
+| `test/*`   | `vitest/*`             |
+| `next/*`   | `@next/next`           |
+
+Use the new prefix when overriding or disabling rules:
+
+```ts
+// eslint-disable-next-line ts/consistent-type-definitions
+type Foo = { bar: 2 };
+```
+
+## Type-Aware Rules
+
+Enable TypeScript type checking:
+
+```js
+export default antfu({
+  typescript: {
+    tsconfigPath: 'tsconfig.json',
+  },
+});
+```
+
+## Config Composer API
+
+Chain methods for flexible composition:
+
+```js
+export default antfu()
+  .prepend(/* configs before main */)
+  .override('antfu/stylistic/rules', {
+    rules: {
+      'style/generator-star-spacing': ['error', { after: true, before: false }],
+    },
+  })
+  .renamePlugins({
+    'old-prefix': 'new-prefix',
+  });
+```
+
+## Less Opinionated Mode
+
+Disable Anthony's most opinionated rules:
+
+```js
+export default antfu({
+  lessOpinionated: true,
+});
+```
+
+## Lint-Staged Setup
+
+```json
+{
+  "simple-git-hooks": {
+    "pre-commit": "pnpm lint-staged"
+  },
+  "lint-staged": {
+    "*": "eslint --fix"
+  }
+}
+```
+
+```bash
+pnpm add -D lint-staged simple-git-hooks
+npx simple-git-hooks
+```
+
+## VS Code Settings
+
+Add to `.vscode/settings.json`:
+
+```jsonc
+{
+  "prettier.enable": false,
+  "editor.formatOnSave": false,
+  "editor.codeActionsOnSave": {
+    "source.fixAll.eslint": "explicit",

+export default defineConfig({
+  entry: ['src/index.ts', 'src/utils.ts'],
+  format: ['esm'],
+  dts: true,
+  exports: true,
+});
+```
+
+The `exports: true` option auto-generates the `exports` field in `package.json` when running `tsdown`.
+
+---
+
+## package.json
+
+Required fields for pure ESM library:
+
+```json
+{
+  "type": "module",
+  "main": "./dist/index.mjs",
+  "module": "./dist/index.mjs",
+  "types": "./dist/index.d.mts",

+    "prepack": "pnpm build",
+    "test": "vitest",
+    "release": "bumpp -r"
+  }
+}
+```
+
+The `exports` field is managed by tsdown when `exports: true`.
+
+### prepack Script
+
+For each public package, add `"prepack": "pnpm build"` to `scripts`. This ensures the package is automatically built before publishing (e.g., when running `npm publish` or `pnpm publish`). This prevents accidentally publishing stale or missing build artifacts.

+    "build": "tsdown",
+    "prepack": "pnpm build"
+  }
+}
+```
+
+## ESLint Cache
+
+```json
+{
+  "scripts": {
+    "lint": "eslint . --cache --concurrency=auto"
+  }
+}
+```
+
+## Turborepo (Optional)
+
+For monorepos with many packages or long build times, use Turborepo for task orchestration and caching.
+
+See the dedicated Turborepo skill for detailed configuration.
+
+## Centralized Alias
+
+For better DX across Vite, Nuxt, Vitest configs, create a centralized `alias.ts` at project root:
+
+```ts
+// alias.ts
+import fs from 'node:fs';
+import { fileURLToPath } from 'node:url';
+import { join, relative } from 'pathe';
+
+const root = fileURLToPath(new URL('.', import.meta.url));
+const r = (path: string) => fileURLToPath(new URL(`./packages/${path}`, import.meta.url));
+
+export const alias = {
+  '@myorg/core': r('core/src/index.ts'),
+  '@myorg/utils': r('utils/src/index.ts'),
+  '@myorg/ui': r('ui/src/index.ts'),
+  // Add more aliases as needed
+};
+
+// Auto-update tsconfig.alias.json paths
+const raw = fs.readFileSync(join(root, 'tsconfig.alias.json'), 'utf-8').trim();
+const tsconfig = JSON.parse(raw);
+tsconfig.compilerOptions.paths = Object.fromEntries(
+  Object.entries(alias).map(([key, value]) => [key, [`./${relative(root, value)}`]]),
+);
+const newRaw = JSON.stringify(tsconfig, null, 2);
+if (newRaw !== raw) fs.writeFileSync(join(root, 'tsconfig.alias.json'), `${newRaw}\n`, 'utf-8');
+```
+
+Then update the `tsconfig.json` to use the alias file:
+
+```json
+{
+  "extends": ["./tsconfig.alias.json"]
+}
+```
+
+### Using Alias in Configs
+
+Reference the centralized alias in all config files:
+
+```ts
+// vite.config.ts
+import { alias } from './alias';
+
+export default defineConfig({
+  resolve: { alias },
+});
+```
+
+```ts
+// nuxt.config.ts
+import { alias } from './alias';
+
+export default defineNuxtConfig({
+  alias,
+});
+```

+
+# Architecture Patterns
+
+Master proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to build maintainable, testable, and scalable systems.
+
+## When to Use This Skill
+
+- Designing new backend systems from scratch
+- Refactoring monolithic applications for better maintainability
+- Establishing architecture standards for your team
+- Migrating from tightly coupled to loosely coupled architectures
+- Implementing domain-driven design principles
+- Creating testable and mockable codebases
+- Planning microservices decomposition
+
+## Core Concepts
+
+### 1. Clean Architecture (Uncle Bob)
+
+**Layers (dependency flows inward):**
+
+- **Entities**: Core business models
+- **Use Cases**: Application business rules
+- **Interface Adapters**: Controllers, presenters, gateways
+- **Frameworks & Drivers**: UI, database, external services
+
+**Key Principles:**
+
+- Dependencies point inward
+- Inner layers know nothing about outer layers
+- Business logic independent of frameworks
+- Testable without UI, database, or external services
+
+### 2. Hexagonal Architecture (Ports and Adapters)
+
+**Components:**
+
+- **Domain Core**: Business logic
+- **Ports**: Interfaces defining interactions
+- **Adapters**: Implementations of ports (database, REST, message queue)
+
+**Benefits:**
+
+- Swap implementations easily (mock for testing)
+- Technology-agnostic core
+- Clear separation of concerns
+
+### 3. Domain-Driven Design (DDD)
+
+**Strategic Patterns:**
+
+- **Bounded Contexts**: Separate models for different domains
+- **Context Mapping**: How contexts relate
+- **Ubiquitous Language**: Shared terminology
+
+**Tactical Patterns:**
+
+- **Entities**: Objects with identity
+- **Value Objects**: Immutable objects defined by attributes
+- **Aggregates**: Consistency boundaries
+- **Repositories**: Data access abstraction
+- **Domain Events**: Things that happened
+

+
+## Best Practices
+
+1. **Dependency Rule**: Dependencies always point inward
+2. **Interface Segregation**: Small, focused interfaces
+3. **Business Logic in Domain**: Keep frameworks out of core
+4. **Test Independence**: Core testable without infrastructure
+5. **Bounded Contexts**: Clear domain boundaries
+6. **Ubiquitous Language**: Consistent terminology
+7. **Thin Controllers**: Delegate to use cases
+8. **Rich Domain Models**: Behavior with data
+
+## Common Pitfalls
+
+- **Anemic Domain**: Entities with only data, no behavior
+- **Framework Coupling**: Business logic depends on frameworks
+- **Fat Controllers**: Business logic in controllers
+- **Repository Leakage**: Exposing ORM objects
+- **Missing Abstractions**: Concrete dependencies in core
+- **Over-Engineering**: Clean architecture for simple CRUD

+
+# Better Auth Integration Guide
+
+**Always consult [better-auth.com/docs](https://better-auth.com/docs) for code examples and latest API.**
+
+Better Auth is a TypeScript-first, framework-agnostic auth framework supporting email/password, OAuth, magic links, passkeys, and more via plugins.
+
+---
+
+## Quick Reference
+
+### Environment Variables
+
+- `BETTER_AUTH_SECRET` - Encryption secret (min 32 chars). Generate: `openssl rand -base64 32`
+- `BETTER_AUTH_URL` - Base URL (e.g., `https://example.com`)
+
+Only define `baseURL`/`secret` in config if env vars are NOT set.
+
+### File Location
+
+CLI looks for `auth.ts` in: `./`, `./lib`, `./utils`, or under `./src`. Use `--config` for custom path.
+
+### CLI Commands
+
+- `npx @better-auth/cli@latest migrate` - Apply schema (built-in adapter)
+- `npx @better-auth/cli@latest generate` - Generate schema for Prisma/Drizzle
+- `npx @better-auth/cli mcp --cursor` - Add MCP to AI tools
+
+**Re-run after adding/changing plugins.**
+
+---
+
+## Core Config Options
+
+| Option             | Notes                                          |
+| ------------------ | ---------------------------------------------- |
+| `appName`          | Optional display name                          |
+| `baseURL`          | Only if `BETTER_AUTH_URL` not set              |
+| `basePath`         | Default `/api/auth`. Set `/` for root.         |
+| `secret`           | Only if `BETTER_AUTH_SECRET` not set           |
+| `database`         | Required for most features. See adapters docs. |
+| `secondaryStorage` | Redis/KV for sessions & rate limits            |
+| `emailAndPassword` | `{ enabled: true }` to activate                |
+| `socialProviders`  | `{ google: { clientId, clientSecret }, ... }`  |
+| `plugins`          | Array of plugins                               |
+| `trustedOrigins`   | CSRF whitelist                                 |
+
+---
+
+## Database
+
+**Direct connections:** Pass `pg.Pool`, `mysql2` pool, `better-sqlite3`, or `bun:sqlite` instance.
+
+**ORM adapters:** Import from `better-auth/adapters/drizzle`, `better-auth/adapters/prisma`, `better-auth/adapters/mongodb`.
+
+**Critical:** Better Auth uses adapter model names, NOT underlying table names. If Prisma model is `User` mapping to table `users`, use `modelName: "user"` (Prisma reference), not `"users"`.
+
+---
+
+## Session Management
+
+**Storage priority:**
+
+1. If `secondaryStorage` defined → sessions go there (not DB)
+2. Set `session.storeSessionInDatabase: true` to also persist to DB
+3. No database + `cookieCache` → fully stateless mode
+
+**Cookie cache strategies:**
+
+- `compact` (default) - Base64url + HMAC. Smallest.
+- `jwt` - Standard JWT. Readable but signed.
+- `jwe` - Encrypted. Maximum security.
+
+**Key options:** `session.expiresIn` (default 7 days), `session.updateAge` (refresh interval), `session.cookieCache.maxAge`, `session.cookieCache.version` (change to invalidate all sessions).
+
+---
+
+## User & Account Config
+
+**User:** `user.modelName`, `user.fields` (column mapping), `user.additionalFields`, `user.changeEmail.enabled` (disabled by default), `user.deleteUser.enabled` (disabled by default).
+
+**Account:** `account.modelName`, `account.accountLinking.enabled`, `account.storeAccountCookie` (for stateless OAuth).
+
+**Required for registration:** `email` and `name` fields.
+
+---
+
+## Email Flows
+
+- `emailVerification.sendVerificationEmail` - Must be defined for verification to work
+- `emailVerification.sendOnSignUp` / `sendOnSignIn` - Auto-send triggers
+- `emailAndPassword.sendResetPassword` - Password reset email handler
+
+---
+
+## Security
+
+**In `advanced`:**
+
+- `useSecureCookies` - Force HTTPS cookies
+- `disableCSRFCheck` - ⚠️ Security risk
+- `disableOriginCheck` - ⚠️ Security risk
+- `crossSubDomainCookies.enabled` - Share cookies across subdomains
+- `ipAddress.ipAddressHeaders` - Custom IP headers for proxies
+- `database.generateId` - Custom ID generation or `"serial"`/`"uuid"`/`false`
+
+**Rate limiting:** `rateLimit.enabled`, `rateLimit.window`, `rateLimit.max`, `rateLimit.storage` ("memory" | "database" | "secondary-storage").
+
+---
+
+## Hooks
+
+**Endpoint hooks:** `hooks.before` / `hooks.after` - Array of `{ matcher, handler }`. Use `createAuthMiddleware`. Access `ctx.path`, `ctx.context.returned` (after), `ctx.context.session`.
+
+**Database hooks:** `databaseHooks.user.create.before/after`, same for `session`, `account`. Useful for adding default values or post-creation actions.
+
+**Hook context (`ctx.context`):** `session`, `secret`, `authCookies`, `password.hash()`/`verify()`, `adapter`, `internalAdapter`, `generateId()`, `tables`, `baseURL`.
+
+---
+
+## Plugins
+
+**Import from dedicated paths for tree-shaking:**
+
+```
+import { twoFactor } from "better-auth/plugins/two-factor"
+```
+
+NOT `from "better-auth/plugins"`.
+
+**Popular plugins:** `twoFactor`, `organization`, `passkey`, `magicLink`, `emailOtp`, `username`, `phoneNumber`, `admin`, `apiKey`, `bearer`, `jwt`, `multiSession`, `sso`, `oauthProvider`, `oidcProvider`, `openAPI`, `genericOAuth`.
+
+Client plugins go in `createAuthClient({ plugins: [...] })`.
+
+---
+
+## Client
+
+Import from: `better-auth/client` (vanilla), `better-auth/react`, `better-auth/vue`, `better-auth/svelte`, `better-auth/solid`.
+
+Key methods: `signUp.email()`, `signIn.email()`, `signIn.social()`, `signOut()`, `useSession()`, `getSession()`, `revokeSession()`, `revokeSessions()`.
+
+---
+
+## Type Safety
+
+Infer types: `typeof auth.$Infer.Session`, `typeof auth.$Infer.Session.user`.
+
+For separate client/server projects: `createAuthClient<typeof auth>()`.
+
+---
+
+## Common Gotchas
+
+1. **Model vs table name** - Config uses ORM model name, not DB table name
+2. **Plugin schema** - Re-run CLI after adding plugins
+3. **Secondary storage** - Sessions go there by default, not DB
+4. **Cookie cache** - Custom session fields NOT cached, always re-fetched
+5. **Stateless mode** - No DB = session in cookie only, logout on cache expiry
+6. **Change email flow** - Sends to current email first, then new email

+description: 'You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.'

+
+# Brainstorming Ideas Into Designs
+
+## Overview
+
+Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
+
+Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.
+
+<HARD-GATE>
+Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.
+</HARD-GATE>
+
+## Anti-Pattern: "This Is Too Simple To Need A Design"
+
+Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.
+
+## Checklist
+
+You MUST create a task for each of these items and complete them in order:
+
+1. **Explore project context** — check files, docs, recent commits
+2. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria
+3. **Propose 2-3 approaches** — with trade-offs and your recommendation
+4. **Present design** — in sections scaled to their complexity, get user approval after each section
+5. **Write design doc** — save to `docs/plans/YYYY-MM-DD-<topic>-design.md` and commit
+6. **Transition to implementation** — invoke writing-plans skill to create implementation plan
+
+## Process Flow
+
+```dot
+digraph brainstorming {
+    "Explore project context" [shape=box];
+    "Ask clarifying questions" [shape=box];
+    "Propose 2-3 approaches" [shape=box];
+    "Present design sections" [shape=box];
+    "User approves design?" [shape=diamond];
+    "Write design doc" [shape=box];
+    "Invoke writing-plans skill" [shape=doublecircle];
+
+    "Explore project context" -> "Ask clarifying questions";
+    "Ask clarifying questions" -> "Propose 2-3 approaches";
+    "Propose 2-3 approaches" -> "Present design sections";
+    "Present design sections" -> "User approves design?";
+    "User approves design?" -> "Present design sections" [label="no, revise"];
+    "User approves design?" -> "Write design doc" [label="yes"];
+    "Write design doc" -> "Invoke writing-plans skill";
+}
+```
+
+**The terminal state is invoking writing-plans.** Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.
+
+## The Process
+
+**Understanding the idea:**
+
+- Check out the current project state first (files, docs, recent commits)
+- Ask questions one at a time to refine the idea
+- Prefer multiple choice questions when possible, but open-ended is fine too
+- Only one question per message - if a topic needs more exploration, break it into multiple questions
+- Focus on understanding: purpose, constraints, success criteria
+
+**Exploring approaches:**
+
+- Propose 2-3 different approaches with trade-offs
+- Present options conversationally with your recommendation and reasoning
+- Lead with your recommended option and explain why
+
+**Presenting the design:**
+
+- Once you believe you understand what you're building, present the design
+- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced
+- Ask after each section whether it looks right so far
+- Cover: architecture, components, data flow, error handling, testing
+- Be ready to go back and clarify if something doesn't make sense
+
+## After the Design
+
+**Documentation:**
+
+- Write the validated design to `docs/plans/YYYY-MM-DD-<topic>-design.md`
+- Use elements-of-style:writing-clearly-and-concisely skill if available
+- Commit the design document to git
+
+**Implementation:**
+
+- Invoke the writing-plans skill to create a detailed implementation plan
+- Do NOT invoke any other skill. writing-plans is the next step.
+
+## Key Principles
+
+- **One question at a time** - Don't overwhelm with multiple questions
+- **Multiple choice preferred** - Easier to answer than open-ended when possible
+- **YAGNI ruthlessly** - Remove unnecessary features from all designs
+- **Explore alternatives** - Always propose 2-3 approaches before settling
+- **Incremental validation** - Present design, get approval before moving on
+- **Be flexible** - Go back and clarify when something doesn't make sense

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+name: canvas-design
+description: Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
+license: Complete terms in LICENSE.txt
+---
+
+These are instructions for creating design philosophies - aesthetic movements that are then EXPRESSED VISUALLY. Output only .md files, .pdf files, and .png files.
+
+Complete this in two steps:
+
+1. Design Philosophy Creation (.md file)
+2. Express by creating it on a canvas (.pdf file or .png file)
+
+First, undertake this task:
+
+## DESIGN PHILOSOPHY CREATION
+
+To begin, create a VISUAL PHILOSOPHY (not layouts or templates) that will be interpreted through:
+
+- Form, space, color, composition
+- Images, graphics, shapes, patterns
+- Minimal text as visual accent
+
+### THE CRITICAL UNDERSTANDING
+
+- What is received: Some subtle input or instructions by the user that should be taken into account, but used as a foundation; it should not constrain creative freedom.
+- What is created: A design philosophy/aesthetic movement.
+- What happens next: Then, the same version receives the philosophy and EXPRESSES IT VISUALLY - creating artifacts that are 90% visual design, 10% essential text.
+
+Consider this approach:
+
+- Write a manifesto for an art movement
+- The next phase involves making the artwork
+
+The philosophy must emphasize: Visual expression. Spatial communication. Artistic interpretation. Minimal words.
+
+### HOW TO GENERATE A VISUAL PHILOSOPHY
+
+**Name the movement** (1-2 words): "Brutalist Joy" / "Chromatic Silence" / "Metabolist Dreams"
+
+**Articulate the philosophy** (4-6 paragraphs - concise but complete):
+
+To capture the VISUAL essence, express how the philosophy manifests through:
+
+- Space and form
+- Color and material
+- Scale and rhythm
+- Composition and balance
+- Visual hierarchy
+
+**CRITICAL GUIDELINES:**
+
+- **Avoid redundancy**: Each design aspect should be mentioned once. Avoid repeating points about color theory, spatial relationships, or typographic principles unless adding new depth.
+- **Emphasize craftsmanship REPEATEDLY**: The philosophy MUST stress multiple times that the final work should appear as though it took countless hours to create, was labored over with care, and comes from someone at the absolute top of their field. This framing is essential - repeat phrases like "meticulously crafted," "the product of deep expertise," "painstaking attention," "master-level execution."
+- **Leave creative space**: Remain specific about the aesthetic direction, but concise enough that the next Claude has room to make interpretive choices also at a extremely high level of craftmanship.
+
+The philosophy must guide the next version to express ideas VISUALLY, not through text. Information lives in design, not paragraphs.
+
+### PHILOSOPHY EXAMPLES
+
+**"Concrete Poetry"**
+Philosophy: Communication through monumental form and bold geometry.
+Visual expression: Massive color blocks, sculptural typography (huge single words, tiny labels), Brutalist spatial divisions, Polish poster energy meets Le Corbusier. Ideas expressed through visual weight and spatial tension, not explanation. Text as rare, powerful gesture - never paragraphs, only essential words integrated into the visual architecture. Every element placed with the precision of a master craftsman.
+
+**"Chromatic Language"**
+Philosophy: Color as the primary information system.
+Visual expression: Geometric precision where color zones create meaning. Typography minimal - small sans-serif labels letting chromatic fields communicate. Think Josef Albers' interaction meets data visualization. Information encoded spatially and chromatically. Words only to anchor what color already shows. The result of painstaking chromatic calibration.
+
+**"Analog Meditation"**
+Philosophy: Quiet visual contemplation through texture and breathing room.
+Visual expression: Paper grain, ink bleeds, vast negative space. Photography and illustration dominate. Typography whispered (small, restrained, serving the visual). Japanese photobook aesthetic. Images breathe across pages. Text appears sparingly - short phrases, never explanatory blocks. Each composition balanced with the care of a meditation practice.
+
+**"Organic Systems"**
+Philosophy: Natural clustering and modular growth patterns.
+Visual expression: Rounded forms, organic arrangements, color from nature through architecture. Information shown through visual diagrams, spatial relationships, iconography. Text only for key labels floating in space. The composition tells the story through expert spatial orchestration.
+
+**"Geometric Silence"**
+Philosophy: Pure order and restraint.
+Visual expression: Grid-based precision, bold photography or stark graphics, dramatic negative space. Typography precise but minimal - small essential text, large quiet zones. Swiss formalism meets Brutalist material honesty. Structure communicates, not words. Every alignment the work of countless refinements.
+
+_These are condensed examples. The actual design philosophy should be 4-6 substantial paragraphs._
+
+### ESSENTIAL PRINCIPLES
+
+- **VISUAL PHILOSOPHY**: Create an aesthetic worldview to be expressed through design
+- **MINIMAL TEXT**: Always emphasize that text is sparse, essential-only, integrated as visual element - never lengthy
+- **SPATIAL EXPRESSION**: Ideas communicate through space, form, color, composition - not paragraphs
+- **ARTISTIC FREEDOM**: The next Claude interprets the philosophy visually - provide creative room
+- **PURE DESIGN**: This is about making ART OBJECTS, not documents with decoration
+- **EXPERT CRAFTSMANSHIP**: Repeatedly emphasize the final work must look meticulously crafted, labored over with care, the product of countless hours by someone at the top of their field
+
+**The design philosophy should be 4-6 paragraphs long.** Fill it with poetic design philosophy that brings together the core vision. Avoid repeating the same points. Keep the design philosophy generic without mentioning the intention of the art, as if it can be used wherever. Output the design philosophy as a .md file.
+
+---
+
+## DEDUCING THE SUBTLE REFERENCE
+
+**CRITICAL STEP**: Before creating the canvas, identify the subtle conceptual thread from the original request.
+
+**THE ESSENTIAL PRINCIPLE**:
+The topic is a **subtle, niche reference embedded within the art itself** - not always literal, always sophisticated. Someone familiar with the subject should feel it intuitively, while others simply experience a masterful abstract composition. The design philosophy provides the aesthetic language. The deduced topic provides the soul - the quiet conceptual DNA woven invisibly into form, color, and composition.
+
+This is **VERY IMPORTANT**: The reference must be refined so it enhances the work's depth without announcing itself. Think like a jazz musician quoting another song - only those who know will catch it, but everyone appreciates the music.
+
+---
+
+## CANVAS CREATION
+
+With both the philosophy and the conceptual framework established, express it on a canvas. Take a moment to gather thoughts and clear the mind. Use the design philosophy created and the instructions below to craft a masterpiece, embodying all aspects of the philosophy with expert craftsmanship.
+
+**IMPORTANT**: For any type of content, even if the user requests something for a movie/game/book, the approach should still be sophisticated. Never lose sight of the idea that this should be art, not something that's cartoony or amateur.
+
+To create museum or magazine quality work, use the design philosophy as the foundation. Create one single page, highly visual, design-forward PDF or PNG output (unless asked for more pages). Generally use repeating patterns and perfect shapes. Treat the abstract philosophical design as if it were a scientific bible, borrowing the visual language of systematic observation—dense accumulation of marks, repeated elements, or layered patterns that build meaning through patient repetition and reward sustained viewing. Add sparse, clinical typography and systematic reference markers that suggest this could be a diagram from an imaginary discipline, treating the invisible subject with the same reverence typically reserved for documenting observable phenomena. Anchor the piece with simple phrase(s) or details positioned subtly, using a limited color palette that feels intentional and cohesive. Embrace the paradox of using analytical visual language to express ideas about human experience: the result should feel like an artifact that proves something ephemeral can be studied, mapped, and understood through careful attention. This is true art.
+
+**Text as a contextual element**: Text is always minimal and visual-first, but let context guide whether that means whisper-quiet labels or bold typographic gestures. A punk venue poster might have larger, more aggressive type than a minimalist ceramics studio identity. Most of the time, font should be thin. All use of fonts must be design-forward and prioritize visual communication. Regardless of text scale, nothing falls off the page and nothing overlaps. Every element must be contained within the canvas boundaries with proper margins. Check carefully that all text, graphics, and visual elements have breathing room and clear separation. This is non-negotiable for professional execution. **IMPORTANT: Use different fonts if writing text. Search the `./canvas-fonts` directory. Regardless of approach, sophistication is non-negotiable.**
+
+Download and use whatever fonts are needed to make this a reality. Get creative by making the typography actually part of the art itself -- if the art is abstract, bring the font onto the canvas, not typeset digitally.
+
+To push boundaries, follow design instinct/intuition while using the philosophy as a guiding principle. Embrace ultimate design freedom and choice. Push aesthetics and design to the frontier.
+
+**CRITICAL**: To achieve human-crafted quality (not AI-generated), create work that looks like it took countless hours. Make it appear as though someone at the absolute top of their field labored over every detail with painstaking care. Ensure the composition, spacing, color choices, typography - everything screams expert-level craftsmanship. Double-check that nothing overlaps, formatting is flawless, every detail perfect. Create something that could be shown to people to prove expertise and rank as undeniably impressive.
+
+Output the final result as a single, downloadable .pdf or .png file, alongside the design philosophy used as a .md file.
+
+---
+
+## FINAL STEP
+
+**IMPORTANT**: The user ALREADY said "It isn't perfect enough. It must be pristine, a masterpiece if craftsmanship, as if it were about to be displayed in a museum."
+
+**CRITICAL**: To refine the work, avoid adding more graphics; instead refine what has been created and make it extremely crisp, respecting the design philosophy and the principles of minimalism entirely. Rather than adding a fun filter or refactoring a font, consider how to make the existing composition more cohesive with the art. If the instinct is to call a new function or draw a new shape, STOP and instead ask: "How can I make what's already here more of a piece of art?"
+
+Take a second pass. Go back to the code and refine/polish further to make this a philosophically designed masterpiece.
+
+## MULTI-PAGE OPTION
+
+To create additional pages when requested, create more creative pages along the same lines as the design philosophy but distinctly different as well. Bundle those pages in the same .pdf or many .pngs. Treat the first page as just a single page in a whole coffee table book waiting to be filled. Make the next pages unique twists and memories of the original. Have them almost tell a story in a very tasteful way. Exercise full creative freedom.
