+### 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.

-# npm `@next` prerelease lane
-
-Status: **IMPLEMENTED**
-
-## Current behavior
-
-`tools/install.sh --next` provides the prerelease integration lane for the permanent `next` branch.
-
-The lane is fast-by-default:
-
-1. Install framework files from the `next` source archive.
-2. Resolve the Gitea npm registry `next` dist-tag for the globally installed packages:
-
-   ```bash
-   npm view @mosaicstack/gateway@next version
-   npm view @mosaicstack/mosaic@next version
-   ```
-
-3. Require both resolved versions to share the same `next.<pipeline>` suffix, then install the exact resolved versions.
-4. If either `@next` package is missing, unreachable, mismatched, or fails to install, fall back to the source-build path at `next`.
-
-`--next` never hard-fails solely because the prerelease npm dist-tag is unavailable.
-
-## Published packages
-
-The `next` publish pipeline publishes non-private `@mosaicstack/*` packages to the Mosaic Gitea npm registry:
-
-```text
-https://git.mosaicstack.dev/api/packages/mosaicstack/npm/
-```
-
-Observed `next` dist-tags after enabling the pipeline:
-
-```text
-@mosaicstack/mosaic@next  -> 0.0.49-next.1633
-@mosaicstack/gateway@next -> 0.0.7-next.1633
-```
-
-The gateway also publishes a Docker image as `gateway:sha-<short>` on `next` merges. The installer fast path uses the npm gateway package when available; the Docker image is for deployed gateway/runtime harness flows.
-
-## Explicit source lanes
-
-Source builds remain available and are still the authority for explicit ref validation:
-
- `--dev` always builds from source.
- `--ref <ref>` / `MOSAIC_REF=<ref>` wins over `--next` and uses the source path for that exact ref.
-
-## Pipeline shape
-
-1. Trigger on `next` merges.
-2. Compute the next prerelease version from the upcoming stable version plus the Woodpecker pipeline number (`<target-stable>-next.<CI_PIPELINE_NUMBER>`).
-3. Build and publish non-private packages in CI.
-4. Publish to the Mosaic Gitea npm registry with dist-tag `next`.
-5. Keep `latest` untouched; only main/release promotion can update `latest`.
-6. Publish gateway Docker images from `next` as `gateway:sha-<short>` only.
-
-## Guardrails
-
- `@next` is mutable prerelease convenience, not a deployment pin.
- Stable installs continue to use `@latest`.
- Contributor validation remains available through `--dev --ref <branch>`.
- Pipeline output traces every prerelease package back to the source commit on `next`.
- The installer falls back to source rather than hard-failing on prerelease registry issues.

+# #1019 — Zero-timeout queue-guard harness race
+
+- **Issue:** #1019 (parent status remains `believed-fixed, pending jarvis validation`; do not close)
+- **Branch:** `fix/1019-ci-queue-timeout-harness`
+- **Owner:** `be-coder-08`
+- **Base:** `origin/main` at `5916aeefd6ed12bcac086c6834c7f6c4ae38e1bc`
+- **Charter:** `/home/hermes/agent-work/tl-mosaic/CHARTER-1019-HARNESS-FIX.md`
+
+## Objective
+
+Make `test-ci-queue-wait-tristate.sh` deterministic without changing any asserted outcome. Remove the indiscriminate zero-timeout race, require every status-classification case to prove the provider was observed, and prove the harness-controlled virtual clock is active.
+
+## Scope
+
+- In scope: `packages/mosaic/framework/tools/git/test-ci-queue-wait-tristate.sh` only, plus this evidence scratchpad.
+- Out of scope: guard parsers, D2/D3 behavior, installer/reseed staleness, PR #1060, and issue closure.
+
+## Acceptance criteria
+
+1. RED deterministically reproduces deadline pre-emption before the provider call.
+2. Every case that intends status classification positively proves provider observation.
+3. Pending observes `pending` before deterministic virtual-time expiration.
+4. The virtual clock has a positive interception control; a broken-clock mutant makes the suite red.
+5. The exact CI-base image passes the final harness repeatedly with zero failures.
+6. Baseline gates, independent code/security review, exact-head CI, and coordinator-authorized squash merge pass.
+
+## Plan
+
+1. Add deterministic RED instrumentation for the known merge/provider-unreachable pre-emption.
+2. Replace global `-t 0` with a nonzero timeout interpreted under an event-driven virtual clock; stub sleep without wall waiting.
+3. Add provider-observation and virtual-clock positive controls without changing outcome assertions.
+4. Run focused shell checks, repeat in exact CI-base image, baseline gates, and independent reviews.
+5. Commit with both identity layers, queue-guard plus direct Woodpecker terminal-state verification, push, self-post PR, verify poster/head/CI, obtain coordinator merge authorization, then squash merge without closing #1019.
+
+## Budget
+
+- No explicit token cap supplied. Keep scope to one harness file and one scratchpad; stop/report at the charter's 60% context gate.
+
+## Evidence
+
+- RED, deterministic pre-provider expiry: `evidence/1019-harness-fix/red-pre-provider-expiry.log` — rc 1; merge/provider-unreachable got rc 124 instead of 75, omitted CANNOT_ASSERT, did not observe the status provider, and wrote no additional audit record (four named failures).
+- GREEN host focused harness: `evidence/1019-harness-fix/green-host.log` — rc 0, all outcome classes passed.
+- Load-bearing clock negative control: a temporary same-directory mutant replaced the virtual `date` body with `/bin/date`; `evidence/1019-harness-fix/red-clock-not-intercepted.log` — rc 1 with named `virtual clock interception did not run` failures. The mutant file was removed after the run.
+- Exact CI-base repeat: `git.mosaicstack.dev/mosaicstack/stack/ci-base:latest`, repository mounted read-only, harness work under container `/tmp`; `evidence/1019-harness-fix/ci-image-repeat/summary.log` — **100 pass / 0 fail / 100 total**.
+- Synchronization design: provider-status observation creates the event marker; virtual time is 1000 before the event and 1002 afterward. Pending alone reaches the stubbed no-op sleep and a post-observation deadline check. `-t 1` is uniquely load-bearing because removing it restores the 900-second default deadline at virtual time 1900, which 1002 does not cross. The numeric timeout is subject semantics under virtual time, not a wall-clock synchronization duration.
+
+## Review remediation — semantic timeout vs. liveness bound
+
+Security review found that virtual time remained at 1000 forever before provider observation and stubbed sleep never waited. A regression looping before the status endpoint—or blocking in the first provider call—therefore could prevent `run_guard` from returning, so the post-return provider assertion could never fire.
+
+**General rule:** A timeout usually serves two purposes: semantics and liveness. Removing wall time from semantic synchronization can silently remove the only independent hang bound. Preserve deterministic virtual time for subject semantics, but provide a separately implemented real-clock liveness watchdog and prove that watchdog fires.
+
+Remediation:
+
+- Every guard subject invocation is launched by absolute `/usr/bin/python3` in a new session. Python's internal monotonic `wait(timeout=...)` provides real-clock liveness independently of PATH; expiry kills the entire isolated process group, so neither PATH-front shims nor a blocked provider descendant can retain the capture pipe.
+- Watchdog expiry returns distinct harness rc 90 plus `FAIL HANG watchdog`, separate from subject timeout rc 124.
+- A first attempt using absolute `/usr/bin/timeout -s KILL` passed on GNU coreutils but failed in the exact Alpine CI-base image: BusyBox killed the immediate wrapper while the guard/provider descendants survived and retained the command-substitution pipe. The process-group kill is therefore required behavior, not portability polish.
+- A committed positive control hangs the branch-provider stub before the status endpoint. It must terminate through the watchdog, emit the hang-specific diagnostic, return rc 90, and prove the status provider was never reached.
+- RED before remediation: a temporary ordinary-success mutant hung before provider observation; only an external control could kill the suite (rc 137), and there was no internal hang-specific diagnostic (`red-watchdog-absent.log`).
+- The watchdog mutant/control is load-bearing: removing the internal watchdog leaves the control unable to produce its required rc 90 and diagnostic.
+
+Post-review evidence:
+
+- Host focused harness with process-group watchdog: rc 0 (`green-watchdog-process-group-host.log`).
+- Exact Alpine CI-base focused harness with process-group watchdog: rc 0 (`green-watchdog-ci-image.log`).
+- Hanging ordinary-success mutant: suite rc 1; success returned rc 90, emitted `FAIL HANG watchdog`, and loudly reported that provider/clock observation did not occur (`red-watchdog-fires.log`).
+- Removed-`-t 1` mutant: suite rc 1; pending was terminated by the watchdog instead of producing `ASSERTED_NOT_READY`, proving the explicit timeout is load-bearing (`red-timeout-argument-removed.log`).
+

+# #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.

-# B1 / @next Durable Publish Pipeline — Design
-
-## Objective
-
-Make `next` a durable integration line that publishes the artifacts required by downstream federation boot tests without manual builds.
-
-Every merge to `next` publishes:
-
-1. **npm prerelease packages** to the Gitea npm registry with dist-tag `next`.
-2. **Gateway container image** tagged only as `gateway:sha-<short>`.
-
-The existing stable release behavior remains isolated to `main` / tags.
-
-## Registry verification
-
-Target registry: `https://git.mosaicstack.dev/api/packages/mosaicstack/npm/`.
-
-Pre-implementation checks:
-
- `npm view @mosaicstack/mosaic dist-tags --registry https://git.mosaicstack.dev/api/packages/mosaicstack/npm/ --json` returned a dist-tags object (`latest: 0.0.48`).
- `npm view @mosaicstack/mosaic@latest version --registry https://git.mosaicstack.dev/api/packages/mosaicstack/npm/` resolved `0.0.48`.
- `@next` currently returns 404 because no `next` dist-tag exists yet; this is expected before the first next prerelease publish.
-
-Pipeline design includes a post-publish verification that `npm view @mosaicstack/mosaic@next version` resolves to the exact CI-computed prerelease version. If Gitea fails to honor the `next` dist-tag, the pipeline fails closed.
-
-## Version scheme
-
-The prerelease version is computed at publish time only; no `package.json` version changes are committed.
-
-For each non-private `@mosaicstack/*` package:
-
-```text
-<target-stable>-next.<CI_PIPELINE_NUMBER>
-```
-
-Where:
-
- `CI_PIPELINE_NUMBER` is Woodpecker's monotonic pipeline number.
- `target-stable` is the package's current committed stable version with the patch component incremented.
-  - Example: `@mosaicstack/mosaic` `0.0.48` publishes as `0.0.49-next.1626`.
-  - Example: `@mosaicstack/gateway` `0.0.6` publishes as `0.0.7-next.1626`.
-
-Rationale:
-
- npm semver sorts `0.0.49-next.1627` above `0.0.49-next.1626`.
- The prerelease does not overtake the future stable `0.0.49`.
- The monotonic pipeline number avoids conflicts across repeated `next` merges.
-
-## Branch and tag guardrails
-
-| Pipeline path         | Branch/event                   | Publishes                                               | Forbidden              |
-| --------------------- | ------------------------------ | ------------------------------------------------------- | ---------------------- |
-| stable npm publish    | `main` push/manual or tag      | package versions already committed in package manifests | `@next` dist-tag       |
-| next npm publish      | `next` push/manual only        | CI-computed prereleases with `--tag next`               | `latest` dist-tag      |
-| gateway image         | `main` push/manual or tag      | `sha-<short>` + `latest` on main + tag on tag events    | next prerelease npm    |
-| gateway image         | `next` push/manual only        | `sha-<short>` only                                      | `latest`               |
-| appservice/web images | `main` push/manual or tag only | existing stable image behavior                          | next image publication |
-
-The pipeline has explicit branch checks inside the publish commands as a second fail-closed layer beyond Woodpecker `when` clauses.
-
-## Implementation plan
-
-1. Widen `.woodpecker/publish.yml` top-level `when` to include `next` so the publish pipeline runs on next merges.
-2. Keep existing `publish-npm` on `main` / tags only.
-3. Add `publish-next-npm` for `next` push/manual only:
-   - configure Gitea npm auth from existing `gitea_token` secret as `NPM_TOKEN`;
-   - preflight registry dist-tag metadata;
-   - compute prerelease versions in CI by temporarily editing package manifests in the workspace;
-   - run `pnpm publish ... --tag next` against non-private `@mosaicstack/*` packages;
-   - verify `@mosaicstack/mosaic@next` resolves to the computed version.
-4. Split image `when` anchors:
-   - `image_build_when` includes `next` and is used by `build-gateway`;
-   - `main_image_build_when` keeps appservice/web on main/tags only.
-5. Keep gateway next image destinations to `sha-<short>` only; no `latest` on next.
-
-## Risk controls
-
- Auth/registry failures are fatal.
- No manual image build/push path is introduced.
- No production `latest` tags are touched from `next`.
- No `@latest` npm dist-tags are touched from `next`.
- All changes live in CI config and docs; no runtime source behavior changes.

-
-```text
-Skills sync script not found at ~/.config/mosaic/bin/mosaic-sync-skills

- Resolve framework helper scripts through `tools/_scripts/<name>` first.
- Keep a legacy `bin/<name>` fallback for pre-migration installs.

-# B3 — Wizard completion ordering
-
-## Problem
-
-The wizard printed the success summary / `Mosaic is ready.` during `finalizeStage`, before the gateway configuration stage had completed its daemon health check. If the gateway health gate later failed, the user could see a success claim followed by a gateway failure.
-
-## Diagnosis
-
-`finalizeStage` handled both mutation work and terminal success messaging. Wizard paths then ran `gatewayConfigStage` and `gatewayBootstrapStage` afterward:
-
-1. finalize writes config, links runtime assets, syncs skills, runs doctor;
-2. finalize prints `Installation Summary` + `Mosaic is ready.`;
-3. gateway config starts/waits for daemon health;
-4. gateway bootstrap runs.
-
-The summary needed to be deferred until after the gateway readiness gates.
-
-## Fix
-
- `finalizeStage` now returns a `showSummary()` callback and supports `deferSummary`.
- Wizard/quick-start paths call finalize with `deferSummary: true`.
- `showSummary()` is called only after gateway config reports ready and bootstrap completes, or immediately when the caller explicitly skips gateway setup.
- If gateway health/config reports not ready, the wizard returns/aborts without printing the success summary.
- Folded in adjacent runtime install hint fix for Pi: `curl -fsSL https://pi.dev/install.sh | sh`.

-# B4 — Wizard step deduplication
-
-## Problem
-
-Greenfield wizard testing showed completed wizard steps could be executed again after the menu marked them `[done]`. In practice this made the Providers/API-key flow and Skills flow appear twice in one wizard run.
-
-There was a second related API-key duplication path: when the Providers step was completed with no key, `gatewayConfigStage` still prompted for `ANTHROPIC_API_KEY` during Finish because it only skipped the gateway API-key prompt when `providerKey` was non-empty.
-
-## Diagnosis
-
- `runMenuLoop` labeled completed sections with `[done]`, but still dispatched the selected step again if the user selected that row.
- Quick Start ran Providers and Skills but did not mark those sections complete in `completedSections`.
- `runFinishPath`/`quickStartPath` defaulted `providerType` to `none` for gateway config, which made it impossible for `gatewayConfigStage` to distinguish:
-  - provider step completed and user intentionally skipped the key, vs.
-  - provider step was never run.
-
-## Fix
-
- Added a shared menu section key helper and a completed-step guard in `runMenuLoop`.
- Completed menu steps now log a skip message instead of re-running their stage.
- Quick Start marks Providers and Skills complete after running them.
- Finish/Quick Start now pass `state.providerType` as-is to gateway config instead of defaulting to `none`.
- `gatewayConfigStage` treats `providerType: 'none'` as an explicit completed provider setup with no key and skips the second gateway API-key prompt.
-
-## Verification
-
- Added unified wizard regression coverage asserting repeated Providers/Skills menu selections only execute each stage once.

-# FED-M3-10 — Federation M3 Integration Tests
-
-## Objective
-
-Add single-gateway gateway integration tests for M3 acceptance #6 and #7.
-
-## Branch / base
-
- Branch: `feat/federation-m3-integration`
- Base: `origin/next` (`838701bd` after M3-06/#683 merge)
- PR base when unblocked: `next`
-
-## Scope
-
- Real PostgreSQL via `@mosaicstack/db`.
- Mocked TLS context / Fastify request shim for `FederationAuthGuard`.
- Direct controller calls using the real M3 route contract: `POST /api/federation/v1/list/:resource` with body `{ limit?, cursor? }`.
- Gated by `FEDERATED_INTEGRATION=1`.
- No federation harness dependency.
-
-## Fixture notes
-
-Aligned with the B2 seed design vocabulary:
-
- `tasks` visibility uses personal `projects` + `missions` chain.
- `notes` are `mission_tasks.notes`; the integration suite asserts subject-only note visibility on an authorized mission.
- Seed includes a second user and unauthorized team/project tasks to prove exclusion from the max-row-cap list result.
- Grants/peers are direct DB fixtures; cert auth still runs through `FederationAuthGuard` using real X.509 certs generated by existing test helpers.
-
-## Current implementation
-
-Added `apps/gateway/src/__tests__/integration/federation-m3-list.integration.test.ts` covering:
-
-1. M3 #6 — cert missing Mosaic OIDs returns 401 federation `unauthorized` envelope.
-2. M3 #6 — valid cert whose grant row is `revoked` returns 403 federation `forbidden` envelope.
-3. M3 #7 — active grant with `max_rows_per_query: 2` caps `list tasks`, returns `_truncated` + `nextCursor`, source-tags rows, and excludes other-user / unauthorized-team tasks.
-4. Cross-user notes invariant — subject can list their own `mission_tasks.notes` row while another user's note on the same authorized mission is excluded.
-5. Unsupported-resource invariant — `list widgets` fails closed with a federation `scope_violation` envelope.

-# Installer `--next` fast npm lane — 2026-06-25
-
-## Scope
-
-Flip `tools/install.sh --next` from source-build-first to fast npm `@next` first, with source fallback.
-
-## Registry reality check
-
-Gitea npm registry: `https://git.mosaicstack.dev/api/packages/mosaicstack/npm/`
-
-Verified before implementation:
-
- `@mosaicstack/mosaic@next` resolves to `0.0.49-next.1633`.
- `@mosaicstack/gateway@next` resolves to `0.0.7-next.1633`.
- `@mosaicstack/gateway` dist-tags include `latest: 0.0.6` and `next: 0.0.7-next.1633`.
- `apps/gateway/package.json` is non-private and has Gitea npm `publishConfig`.
-
-Conclusion: the installer can fast-install both CLI and gateway npm packages for `--next`. The gateway Docker `gateway:sha-<short>` remains the deployment/harness artifact; the npm gateway package is valid for the installer global package path.
-
-## Behavior
-
- `--next` with no explicit ref:
-  1. framework archive from `next`;
-  2. resolve `@mosaicstack/gateway@next` and `@mosaicstack/mosaic@next`;
-  3. require both resolved versions to share the same `next.<pipeline>` suffix;
-  4. install the exact resolved package versions;
-  5. set `MOSAIC_GATEWAY_SKIP_NPM_INSTALL=1` so wizard does not overwrite the prerelease gateway;
-  6. if either package is missing/unreachable/mismatched/fails, fall back to existing source build at `next`.
- `--dev` remains pure source build.
- explicit `--ref` / `MOSAIC_REF` still wins over `--next` and uses the source path for that exact ref.
-
-## Install detail
-
-The installer writes the scoped npmrc mapping (`@mosaicstack:registry=...`) and then runs npm install without overriding npm's default registry. Passing `--registry=<gitea>` to `npm install` forces public transitive dependencies (for example `@anthropic-ai/sdk`) to resolve from Gitea and breaks the fast path; the scoped npmrc mapping is the correct split-registry behavior.
-
-## Verification notes
-
- Added `tools/install-next-lane.test.sh` with a fake npm/source harness for exact-version fast install, registry failure source fallback, explicit-ref precedence, and mismatched suffix warning.
- Wired the installer harness into `pnpm test` via `pnpm run test:installer`.
- Real temp-prefix fast install succeeded with `@mosaicstack/[email protected]` and `@mosaicstack/[email protected]`.

-# Scratchpad — installer `--next` lane
-
-## Objective
-
-Add a prerelease installer lane for the permanent `next` integration branch.
-
-## Scope
-
- `tools/install.sh`
- README/install documentation
- Follow-up design note for future npm `@next` prerelease publishing
-
-## Plan
-
-1. Add `--next` and `MOSAIC_NEXT=1` as source-build shorthand for `next`.
-2. Preserve explicit ref precedence: `MOSAIC_REF` and `--ref` win over `--next`.
-3. Update installer source display/help text.
-4. Document three lanes:
-   - stable npm `@latest`
-   - prerelease `--next`
-   - contributor `--dev --ref X`
-5. Run shell and repo gates locally, then hold before push/PR until runner serialization greenlight.
-
-## Verification
-
- `bash -n tools/install.sh` — pass.
- `docker run --rm -v "$PWD:/mnt" -w /mnt koalaman/shellcheck:stable tools/install.sh` — pass.
- `bash tools/install.sh --check --framework --next` — source display shows `ref: next, --next prerelease lane`.
- `bash tools/install.sh --check --cli --next --ref feature-x` — source display shows explicit ref wins.
- `MOSAIC_NEXT=1 MOSAIC_REF=feature-env bash tools/install.sh --check --cli` — source display shows explicit env ref wins.
- `pnpm install --frozen-lockfile --prefer-offline --store-dir /home/jarvis/.local/share/pnpm/store` — pass (local override for repo `.npmrc` CI store path).
- `pnpm typecheck` — pass (41 successful tasks).
- `pnpm lint` — pass (23 successful tasks).
- `pnpm format:check` — pass.
- `bash tools/e2e-install-test.sh` — attempted; current baseline fails during gateway health after stable registry install because Valkey is unavailable in the clean container. The `tools/install.sh --yes --no-auto-launch` stage itself completed before the downstream gateway verification failure.

+# PR merge squash message field
+
+- **Charter:** `/home/hermes/agent-work/CHARTER-PRMERGE-MESSAGE-FIELD.md`
+- **Owner:** `be-coder-08`
+- **Branch:** `fix/pr-merge-message-field`
+- **Base:** remote `main` / local `origin/main` at `85d2108e4ed15c744ad3b87a5b629e7b2d39405a`
+- **Estate:** HOMELAB tooling shared by HOMELAB and USC
+
+## Objective
+
+Add an optional, identity-checked Gitea squash message to `pr-merge.sh` so genuine multi-author PRs retain non-poster branch authors without weakening hardcoded squash behavior.
+
+## Binding requirements
+
+1. `Do` remains hardcoded to `squash`; no provider/repository default may select merge style.
+2. A verified trailer uses a PR commit's linked `author.login` and that same commit's author email. No `/users/{login}` primary-email lookup occurs. Recorded rationale: this asks only what the provider can answer.
+3. A commit with `author.login` null blocks before merge, prints both the null provider fact and commit email fact, and names the escalation principal.
+4. The BLOCK arm must be observed firing; a normal canonical single-author API payload remains explicit squash plus its reviewed `head_commit_id`.
+5. Every provider mutation is read back from the provider; no real PR is merged during tests.
+
+## Derived interface decisions
+
+- Add `--co-author-trailers` rather than accepting arbitrary message text. The wrapper enumerates PR commits and constructs trailers, making an unchecked `Co-authored-by` line unexpressible.
+- Require `--escalate-to PRINCIPAL` with `--co-author-trailers`, so the BLOCK diagnostic always names a principal rather than a generic role.
+- Do not expose `MergeTitleField` separately. When trailers exist, set it from the provider PR title and set `MergeMessageField` only to construction-generated trailers. This preserves one provider source for the title and avoids an unrelated caller-controlled degree of freedom.
+- Preserve first-commit order and emit one trailer per distinct non-poster `author.login`, using that first linked commit's own email.
+
+## Canonical delivery plan
+
+1. Port the capability into the installed source of truth, `packages/mosaic/framework/tools/git/pr-merge.sh`; do not retain `infra/fleet/tools/git` as a second copy.
+2. Preserve canonical `--expect-head`, exact head branch/repository/SHA queue inspection, Gitea atomic head pinning, GitHub `--match-head-commit`, and delete-after-merge semantics.
+3. Do not port the deployed-only `--skip-queue-guard` bypass. Add the focused harness to the canonical framework-shell suite and re-establish RED/GREEN on the packaged baseline.
+4. Deliver through a reviewed package release followed by `mosaic update` with its default framework reseed. The installer snapshots, manifest-syncs framework-owned `tools/**`, and rolls back on failure.
+5. Before either estate relies on the change, require installed/package hash equality, `MergeMessageField` presence, and a green focused harness. Release/reseed ownership is currently unassigned and blocks activation after source merge.
+
+## Evidence
+
+- RED against the byte-identical deployed baseline (`sha256 08a65e8584c5…`): rc 1 with eight named failures. The wrapper rejected `--co-author-trailers`; the null-login path emitted none of the required BLOCK facts/principal; and both verified/ordinary API paths failed the stdin-config credential assertion (ordinary path exposed the fixture token through curl argv). Log: `/home/hermes/agent-work/be-coder-08/evidence/prmerge-message-field-red.log`.
+- GREEN on the deployed-baseline candidate: verified linked multi-author payload, null-login BLOCK, required named principal, explicit squash, stdin-config token transport, and absence of `/users` lookup all passed. Log: `/home/hermes/agent-work/be-coder-08/evidence/prmerge-message-field-green.log`.
+- RED against canonical packaged baseline `c581ef48…`: rc 1 with 32 assertions. It rejects the new option, and the first harness version did not satisfy canonical head branch/repository/SHA metadata. Log: `/home/hermes/agent-work/be-coder-08/evidence/prmerge-packaged-baseline-red.log`. The port adapts the fixture rather than weakening canonical head controls.
+- Provider capability probe against `git.mosaicstack.dev`: authenticated `be-coder-08` POST to deliberately nonexistent PR `2147483647` with both message fields returned JSON HTTP 404; the unauthenticated same request returned JSON HTTP 401 (not the charter's predicted 403). The authenticated-vs-unauthenticated differential proves write authorization resolved while no mergeable subject existed. `tl-mosaic` ruled the literal non-load-bearing: preserve the observed 404/401 pair and do not manufacture a 403 case. No cause was inferred and no real PR was targeted.
+- Provider-generated trailer behavior is not treated as exclusive or absent. The wrapper's VERIFIED/BLOCK decision binds each requested non-poster trailer to commit `author.login` plus that commit's email; it does not assume `MergeMessageField` is the squash's only trailer source. The poster is omitted from the constructed list because the resulting squash author already records the poster; any additional provider-generated trailer is outside this change's unmeasured mechanism.
+- An early candidate SHA-256 `5de32876990e4f26920448cb3220cc7f1146d558b4dd2bc1ee1a2abee2f2cbe6` passed the initial harness, then author-side review found credential-fallback and argv-exposure defects. The live deployed wrapper was atomically restored to baseline SHA-256 `08a65e8584c52c6d41ea1c686f8b95585c21e4b37320a2447eba09359a0e02c1`; the remediated candidate remains only in the worktree.
+
+## Remediation and current review state
+
+1. Token and Basic Auth now use stdin curl configuration, not argv. PR title, contributor email, and the JSON payload also remain out of child argv.
+2. Each credential attempt binds commit inspection and merge. A token failure during either inspection or mutation causes Basic fallback to repeat inspection before mutation; the payload pins the inspected `head_commit_id`.
+3. Focused tests cover token-resolution fail-closed behavior, both HTTP-401 fallback seams, metadata/credential argv absence, null-login BLOCK, explicit squash, canonical reviewed-head binding, unchanged ordinary payload, and retained log-safe provider diagnostics. Token-resolution RED: `/home/hermes/agent-work/be-coder-08/evidence/prmerge-token-resolution-red.log`.
+4. Codex review rounds 3–5 requested retained provider error text, log-safe provider diagnostics, fail-closed credential fallback, stable value-option parsing, and PR-title trailer-injection prevention. These are remediated with regression assertions. A post-remediation independent review is still required.
+5. **Accepted linkage limitation:** `author.login` resolution proves that the commit address maps to a registered provider account. It does not prove that the named principal authored the commit because Git author metadata is self-asserted. This gate checks attribution linkage, not authorship; commit signing is out of scope and currently unadopted. Coordinators explicitly ruled that this does not add a third state.
+6. Codex's sandbox could not execute the harness because its checkout was read-only; that environmental limitation is recorded separately from host-side test results.
+
+## Disposable provider fixture acceptance
+
+- Use a retained scratch repository only, with two branch authors and `author != committer` on at least one commit.
+- Arm A supplies a message-field trailer for one non-poster; record whether that value lands without forcing the partial-pair result into under-specified `APPENDS`/`REPLACES` labels. Demonstrate an absence control.
+- Arm B includes a registered trailer for a different non-poster on a branch commit; record whether it survives or drops. Verify identity through an existing commit whose `author.login` resolves and demonstrate an absence control.
+- Parse landed trailers key-agnostically with `^[A-Za-z-]+-[Bb]y:` and record generated poster pair presence/absence plus resulting poster attribution.
+- Record `/users/<login>` status and raw email only as non-gating estate telemetry. Never read `active`, `visibility`, or any profile field as an identity gate.
+- Use distinct principals: poster `be-coder-08`, merger `Mos`, Arm A `be-coder-07`, and Arm B `be-coder-06`. Capture every trailer-shaped line verbatim and in order. Zero trailer lines means the generator did not fire and the run is `VOID`, not evidence that either arm dropped.
+- Report the same read-back evidence to `mos-claude` on socket `default` and `tl-mosaic` on socket `mosaic-fleet`. Report values rather than mechanism inferences and stop on any poster-attribution regression.
+
+## Fixture preflight
+
+- Retained public repository: `mosaicstack/prmerge-trailer-fixture`; PR `#1`, posted by `be-coder-08` and reserved for merge by `Mos`.
+- Existing `mosaicstack/stack` commits resolve `be-coder-07` and `be-coder-06` through `author.login`; exact addresses are `[email protected]` and `[email protected]`.
+- Non-gating HOMELAB telemetry for authenticated reader `be-coder-08`: `/api/v1/users/be-coder-06` returned HTTP 200 with raw `email` value `[email protected]`.
+- Provider preflight showed PR commit enumeration is newest-first. A new RED test proved that deriving `head_commit_id` from the final array element selected the wrong commit. The candidate now reads `.head.sha` from the authenticated PR endpoint before enumeration, verifies it appears in the commit set, and atomically pins that SHA in the explicit squash payload. RED: `/home/hermes/agent-work/be-coder-08/evidence/prmerge-head-order-red.log`.
+- Fixture PR head `f6ba6e5105031fa21f5ff7bd8e4379d99c16e1de` has `author.login=be-coder-07`, `committer.login=be-coder-08`, and branch-message trailer `Co-authored-by: be-coder-06 <[email protected]>`.
+
+## Fixture result
+
+- `Mos` merged retained fixture PR `#1` through staged candidate SHA-256 `60e779a85fd13b729d859ea7c986d1e9b1641b97991611329226c1b3113ffb6e`; resulting squash commit: `3f550715d9bc716426fd355a65fe997b3a90fa7d` with one parent.
+- Provider read-back: poster/commit author `be-coder-08`, committer/merger `Mos`. The run is non-void.
+- Trailer-shaped lines, verbatim and in order:
+  1. `Co-authored-by: be-coder-07 <[email protected]>`
+  2. `Co-authored-by: be-coder-08 <[email protected]>`
+- Arm A supplied field value (`be-coder-07`) landed. Arm B branch trailer (`be-coder-06`) dropped. Both fabricated absence controls remained absent. No `Co-committed-by:` line landed.
+- The candidate payload construction explicitly excludes the poster and supplied only the Arm A `be-coder-07` line. Therefore the landed poster line was provider-generated, not candidate-composed. The raw result supports `FIELD LANDS`, `BRANCH DROPS`, and `POSTER GENERATED`; it does not support a claim that candidate code supplied the poster. Evidence: `/home/hermes/agent-work/be-coder-08/evidence/prmerge-fixture-readback.log` and the retained provider object.
+- Retained fixture PR `#2` measured the N=2 shape needed by `#1030`: supplied `be-coder-07` then `be-coder-06`; both landed in that order, followed by the provider-generated poster line. No truncation or dedup occurred at N=2. Resulting squash: `39db9d13aed0…`.
+
+## Current hold point
+
+PR `mosaicstack/stack#1066` is open. Its first frozen head `f4b162fa…` was terminal-green in Woodpecker `mosaic` pipeline `#2225`, but that evidence becomes stale when the canonical port moves the head. The deployed wrapper remains baseline `08a65e85…`; no manual copy will occur. Canonical port tests, commit amendment, rebase, one guarded force-with-lease, exact-head CI, and new independent review remain. Even after source merge, activation remains blocked on an assigned package-release/reseed owner and installed-byte read-back.
+
+## Security review 96 remediation
+
+Exact reviewed predecessor head: `1ceb11058f64dd7f4a817ceb2124f980a1c4dd23`.
+
+RED-first focused harness produced 10 named failures: all curl calls lacked size/time/connect bounds; raw ESC email reached mutation; oversized and stalled curl failures were discarded and reached mutation; nonempty Basic output with resolver rc 91 authorized mutation.
+
+Security remediation:
+
+- Removed the cross-principal HTTP-401 Basic fallback. Both inspection-401 and merge-401 paths now refuse without Basic resolution or mutation; `get_gitea_basic_auth` references in the merge subject are 0.
+- Applied `--max-filesize`, `--max-time`, and `--connect-timeout` to all 3/3 provider curl sites and fail closed on curl transport rc at all 3/3 sites.
+- Required linked email bytes to be ASCII and printable before constructing `MergeMessageField`; guarded construction sites 1/1.
+
+GREEN: message-field, exact-head, empty-UID/API, queue branch/repository/SHA, bash syntax, ShellCheck, and diff check pass. R7 total-removal mutants went RED: email guard 3 rows; bound switches 1 row; transport-rc guards 4 rows; HTTP-401 refusal 3 rows. R7 bound: mutants prove total removal only; explicit denominators above prove site coverage.

 The installer syncs skills from `mosaic/agent-skills` into `~/.config/mosaic/skills/`. Install, wizard finalization, and `mosaic update` automatically reconcile every canonical skill into Claude Code's `~/.claude/skills/` directory.

 Skill names are direct children using `[A-Za-z0-9][A-Za-z0-9._-]*`, not paths. Registration rejects traversal/control characters and never replaces foreign files, directories, or symlinks; unregister removes only links that point inside the canonical Mosaic skill root. After registering during a running Claude Code session, use `/reload-skills` or start a new session.
