+`--next` is shorthand for the prerelease integration lane: it enables source-build mode and uses `next` unless an explicit `--ref` or `MOSAIC_REF` is provided.

-The installer evaluates canonical phases P0–P9 and does not print `Done.` unless every committed postcondition passes. A failed phase exits non-zero, names the phase, and points to its durable journal under `${XDG_STATE_HOME:-~/.local/state}/mosaic/install/`.

 10. ASSUMPTION: **Conversations and messages get their own PG tables** (not stored in brain's entity model). They follow a chat-specific schema with proper foreign keys to users and projects. Rationale: Chat has different access patterns (streaming, pagination, search) than brain entities.
 
 11. RESOLVED: **Pi handles all target LLM providers natively.** Anthropic, OpenAI/Codex, Z.ai, Ollama, LM Studio, and llama.cpp are all supported via Pi's built-in providers or `models.json` configuration with `openai-completions` API type.

-## Greenfield install correctness — C1 (#1050)
-
-### Problem and objective
-
-A from-zero install can report success while leaving the target host unusable because the installer has no transactional state machine capable of certifying its own postconditions. C1 supplies the structural spine and red-first fixture; later cards repair the individual failed postconditions.
-
-### Normative requirements
-
-1. The installer SHALL implement the canonical P0–P9 numbering from the greenfield-install PRD v2: P0 Resolve context; P1 Preflight; P2 Acquire artifacts; P3 Install CLI; P4 Install framework + skills; P5 Identity; P6 Runtime linking / activation; P7 Services; P8 Shell discoverability; P9 Verify + commit. P2 is scoped to installer-distribution artifacts and SHALL NOT foreclose credentialed downstream acquisition. P5 owns validating any credential capability required by requested downstream work; P7 may provision credential-dependent resources only after that P5 postcondition commits.
-2. Every phase SHALL declare preconditions, action, committed postconditions, and rollback. An unverifiable postcondition SHALL fail the install non-zero with the named phase and a remediation line; no best-effort failure may still certify success. P1's required-tool closure includes tools invoked by later phases, including `git`; a downstream prerequisite may not remain undeclared and degrade silently.
-3. A durable mutation journal SHALL open before the first mutation and commit at P9. Fallible command output needed to diagnose a phase SHALL be journaled and surfaced, never discarded.
-4. `--check` SHALL run exactly the P0–P8 postcondition predicates without mutation, report each phase PASS/FAIL, and exit non-zero if any predicate fails.
-5. P4 SHALL consume a checkout-free, lane/versioned shipped-set declaration published by the installer. C1 SHALL NOT select among the currently disagreeing framework-payload, repository-root, sync-source, and W-jarvis populations; while no declaration exists, P4 reports `NOT-MEASURED / UNDECLARED` and remains blocking rather than fabricating a count. C5 owns the declaration's contents and containment/loadability fulfillment.
-6. The from-zero fixture SHALL be lane-parametric, use Debian/glibc, run the documented install command as a non-root target user with an isolated HOME, and inherit no host credentials, npm cache, home directory, or runtime configuration.
-7. The fixture SHALL select `next` with `--next` or `MOSAIC_NEXT=1` and assert the resolved lane version. Internal predicates use P3's absolute CLI path; shell discoverability is tested only at P8.
-8. Fault injection after each P2–P8 phase SHALL prove either clean rollback or a durable, honestly reported resumable partial state, with no journal incorrectly left in progress.

Source resolution/acquisition SHALL fail closed, and the arm SHALL verify the realised source commit and archive digest after installation. Any out-of-scope unpinned sibling SHALL be named and counted rather than silently included in a broader pinning claim. `ASSUMPTION:` the configured repository's authenticated exact-commit endpoint is trusted to map that commit ID to the returned archive bytes; independent signed provenance/authenticity against repository or TLS trust-root compromise remains excluded by canonical greenfield-install PRD v2 §3.

-15. The CI fixture SHALL publish pipeline-level execution coverage for both the unconditional case set derived from the expected-RED manifest and the explicitly declared required pipeline-arm set, including the immutable remote-installer contract. Per-case and per-arm success markers SHALL be run-scoped, stored beneath an existing checkout-archive exclusion, and written only after that arm's verifier passes. A final step SHALL depend on the complete fixture matrix, run after prior success or failure, emit both `cases_defined=N cases_executed=M` and `arms_defined=N arms_executed=M`, and invoke the same testable aggregation helper whose complete case/arm PASS/FAIL truth table is covered. It SHALL fail unless both expected/executed name sets are exactly equal; missing, unexpected, stale, newly added unexecuted, or checkout-contaminating state SHALL fail closed. The archive-purity control SHALL bind to the production checkout-archive selector so deleting the production exclusion makes the control RED. Coverage tooling SHALL execute under both the canonical Alpine/BusyBox CI image and the Debian greenfield image; a green result from either runtime alone is insufficient portability evidence. Expected-set membership SHALL consume a fully materialized producer result so an early-closing consumer cannot turn a valid marker into a `pipefail` rejection.

-### C1 acceptance criteria
-
-1. The pre-C1 from-zero matrix records both discriminating controls: with `git` absent, the legacy installer still exits zero while P1 fails and skill sync degrades; with `git` present, P1 passes and the observed sync store/runtime links are 101/101. The C1 installer must fail at P1 before mutation when `git` is absent.
-2. The discriminating P3 row passes: the binary exists at the expected absolute path and reports exactly the resolved `next` lane version, while P4, P5, and P8 fail.
-3. The `--check` mutation negative control proves host fingerprints are byte-identical before and after observation.
-4. Woodpecker executes and validates the expected RED fixture plus the immutable remote-installer contract; its pipeline-level coverage gate reports exact equality for the manifest-derived case set and the declared arm set, while skipped-case and skipped-remote-arm controls prove non-execution is red. C1 does not repair P4/P5/P8 or activate #869.
-5. Negative controls prove manifest shrink/duplicates/unknown rows fail, unsafe P0/P3/P4/P5 contexts fail, the P2–P8 fault seam enters real actions rather than synthetic writes, empty/mismatched fetched bodies fail, and a deliberately emitted secret canary is redacted from every persisted/output population.
-
-### Explicit exclusions and dependencies
-
-- C2 owns P8/PATH, C3 owns P5/headless identity, C4 owns P6 activation policy, and C5 owns P4/skills.
-- Main-lane execution is a promotion precondition owned by #1037; C1 only makes the fixture lane-parametric.
-- RM-02 and #869 activation are out of scope.

+# 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.

+| `next` push/manual                | CI-computed prereleases, `<target-stable>-next.<CI_PIPELINE_NUMBER>`, published with `npm publish --tag next` | `gateway:sha-<short>` only                                                               |
+
+`next` never publishes npm `latest` or Docker `latest`. The next npm publish step verifies that `@mosaicstack/mosaic@next` resolves to the computed prerelease before the pipeline can pass.

-The phase numbers are a cross-workstream contract and must not be renumbered.
-
-## Side-effect-free check
-
-```bash
-bash tools/install.sh --check          # stable/latest lane
-bash tools/install.sh --check --next   # prerelease lane
-```
-
-`--check`:
-
-- emits exactly one `[P0]` through `[P8]` PASS/FAIL row;
-- exits non-zero if any predicate fails;
-- does not create the npm prefix, lock, journal, manifest, shell profile, or runtime file;
-- uses temporary npm observation storage outside the target HOME and removes it before exit.
-
-P4 currently fails as `NOT-MEASURED / UNDECLARED` until the installer publishes `~/.config/mosaic/.install-shipped-skills.json`. C1 deliberately does not select among the conflicting candidate populations; C5 owns publishing and fulfilling that declaration. Once present, the P4 predicate requires the declaration's lane/version to match the resolved install and every named skill to remain contained under `skills/<name>/SKILL.md` with matching loadable frontmatter.
-
-## Durable journal
-
-Each mutating run creates a private transaction directory:
-
-```text
-${XDG_STATE_HOME:-~/.local/state}/mosaic/install/
-  active.json
-  <UTC-run-id>/
-    journal.ndjson
-    journal.ndjson.sha256   # committed runs only
-    commands.log
-    snapshot/
-```
-
-Before each mutation scope is touched, `journal.ndjson` records:
-
-- phase and path;
-- whether prior state existed and where its snapshot lives;
-- the reversal action;
-- the captured command-output location and command status.
-
-Journal, action-status, manifest, or command-log write/sync failure is fatal. An unrecorded mutation is not allowed. Command diagnostics are redacted before terminal output or durable logging; credential-shaped environment values, bearer values, auth tokens, and credentialed URLs are never deliberately persisted. Successful P9 runs append a seal event, write the SHA-256 sidecar, and make the journal and sidecar read-only. Required P4/P6 action failures are persisted in the manifest so a later `--check` cannot turn a failed action into a false pass.
-
-Rollback roots must be non-overlapping, non-symlinked, target-user-owned strict descendants of canonical `HOME`; unsafe custom `MOSAIC_HOME`/`MOSAIC_PREFIX` values fail at P0. The same validation runs again immediately before recursive rollback. The OS lock is concurrency authority: if a process dies while `active.json` still says `in-progress`, a retry that acquires the free lock preserves the stale projection as `prior-active.json` and proceeds from the honestly retained partial state.
-
-`active.json` is the current projection:
-
-- `in-progress`: incomplete/open transaction;
-- `rolled-back`: a fault restored the snapshot;
-- `rollback-failed`: restoration failed or refused a replaced/unsafe target and requires manual recovery;
-- `failed-resumable`: named postconditions failed and the recorded partial state remains for remediation;
-- `committed`: P9 passed and the journal is sealed.
-
-## Failure recovery
-
-1. Read the named phase and remediation line from installer stderr.
-2. Inspect `active.json`, then the referenced `journal.ndjson` and `commands.log`. Command output needed to diagnose a failure is preserved and surfaced; it is not redirected away.
-3. For `rolled-back`, verify the target paths match their pre-install state before retrying.
-4. For `failed-resumable`, repair the named phase owner requirement, then run `install.sh --check` before retrying the installer.
-5. Do not activate the #869 enforcement hooks merely to turn P6 green. A broker-less host with those hooks is a failed P6 state.
-
-## Greenfield CI gate
-
-`.woodpecker/greenfield-install.yml` runs `tools/e2e-install-test.sh` from zero in Debian/glibc as a non-root uid with `env -i`. No host HOME, npm cache, credentials, or bind mount enters the target process. Checkout mode packages the complete current checkout into an archive, pins its SHA-256 through an internal fixture seam, and copies the self-contained fixture into the container; framework-installer changes in the PR are therefore exercised rather than fetched from an older remote branch.
-
-The C1 fixture intentionally returns an attributable RED while C2–C5 remain open. CI itself remains green only when the fixture's final P0–P9 verdicts, required discriminator rows, seeded secret-canary scan, and non-zero exit match the versioned contract in `tools/fixtures/greenfield-expected-red.tsv`. The comparator validates the complete three-case schema before selecting a case: exactly one exit and P0–P9 disposition per case, pinned require/forbid populations, and no duplicate or unknown rows. Any later remediation that changes an observed verdict makes CI red until the owning lane deliberately updates that manifest:
-
-- `git` present: P1 and strict P3 pass; P4/P5/P6/P8 fail for their own reasons; P9 refuses success.
-- `git` absent: P1 fails before target mutation and the installer emits no `Done.`.
-
-The fixture is lane-parametric:
-
-```bash
-bash tools/e2e-install-test.sh --lane next --git present
-bash tools/e2e-install-test.sh --lane main --git present
-```
-
-CI exercises both lane parameters as expected-RED structural checks. A separate remote-contract arm fetches the installer at the immutable CI commit, rejects failed or empty HTTP-success bodies, compares it to the reviewed `tools/install.sh.sha256`, and executes that exact fetched artifact. The P2–P8 fault matrix runs the real phase actions (including the P3 npm path, P4 framework path, and wizard path) rather than synthetic representative writes, then compares the complete target tree to its pre-install fingerprint. Delivery targets `main` under the trunk-only merge rule; `next` remains a non-merging integration lane. The linked installer issue stays open after merge and closes only after Jarvis independently validates the greenfield behavior.
-
-## Source trust boundary
-
-Remote installer mode requires a non-empty body and an expected SHA-256 before execution. Remote source-archive mode separately pins the resolved commit, records the archive SHA-256, limits compressed/expanded size and entry count, and rejects traversal, links, devices, and special files before extraction. These controls provide immutable run provenance and archive safety, not an independent signing root. Signed artifact metadata/provenance is explicitly deferred by the canonical greenfield PRD; C1 does not invent a signing system. The checkout and remote CI seams verify reviewed digests before executing their artifacts.

-Post-fix mechanism breakdown: fully constrained 5/10 (#1,#4,#5,#7,#9); partially constrained 1/10 (#6); unpinned 4/10 (#2,#3,#8,#10). Same-CI stack payload hops moved from 1/2 to 2/2. The fix does not increase the number of constrained paths; it corrects #7 from wrong identity to intended identity. This census is a LOWER BOUND on defects and an UPPER BOUND on assurance: questioning revised the claimed assurance downward each time (blended 6/10 -> mechanism split -> 5 full + 1 partial + 4 unpinned), never upward.

-- P1 metadata failure blocks before mutation.
-- Failed package install falls back to the one immutable stack archive resolved in P2; source resolution/fetch failure is fatal.
-- #5 CLI: P2 RESOLVED_CLI_VERSION is authoritative; a later installed CLI mismatch is detected by P3 and rolls back.
-- #6 gateway: no authoritative P2 gateway value is persisted. The last resolution in install_next_cli_from_registry wins and is compared with itself, so successful same-suffix gateway drift can be silently accepted. Reported, not fixed.

-- action-failure P6 reason: 4/5
-- dead-hooks-active count=2 P6 reason: 1/5
-- source commit/digest property: PASS 5/5
-- P6 outcome property: FAIL 5/5
-No comparator verdict is claimed. Identical source, digest, and package version produced different comparator values; this gate is nondeterministic on the #869 probe path. Load does not explain the small sample monotonically: run 4 had the highest observed 5/15-minute load but produced rc=0. The 2000ms capability-probe timeout remains a code-read hypothesis, NOT MEASURED as causal.
-
-CHECKOUT CONTROL (EXECUTED, NOT PART OF REMOTE N=5)
-The checkout-source arm independently produced: fixture rc=1; @next CLI 0.0.50-next.2207; P3 PASS; P6 FAIL with dead hooks active count=2; comparator rc=1 with the same 1/19 required-reason miss. This showed that outcome can occur independently of the remote #7 binding; its reproducibility was not separately measured.
-
-PROPERTY / SIGNAL FINDING (MANIFEST UNCHANGED)
-P6=FAIL remains the correct property and is unchanged. The comparator additionally pins one reason signal: "runtime linking/activation action reported a required failure". Exact-source P6 failed on all 5/5 runs, while the reason signal varied. The reason assertion was not widened to fit either observation.
-
-#869 FINDING (BEHAVIOR EXECUTED; ROOT-CAUSE ATTRIBUTION CODE-READ)
-Current @next now carries the lease capability. defaultSupervisorProbe treats bundled launcher+daemon file presence plus a nonempty resolved socket PATH as supervisor presence; it does not require the socket itself to exist. One of five identical clean broker-absent runs wired two dead hooks and let the linker exit zero; four reported the action failure. The 2000ms defaultCapabilityProbe subprocess timeout is a code-read candidate for the variance, NOT MEASURED as causal. Fixing this is #869 scope and was not performed.
-
-TRUST BOUNDARY / INDEPENDENT PROVENANCE
-The exact-commit archive URL binds source identity under the configured repository provider's authenticated mapping of commit ID to response bytes. The computed SHA-256 proves that the bytes executed are the bytes that exact URL served and that they did not change between fetch, installer consumption, and manifest verify-after. That is the measured control against stale-next substitution: SOURCE-CONTROL passed 5/5 exact-source runs and failed when R7 deleted the binding. The digest does NOT prove that those bytes are what the repository's authors published if the repository service or TLS trust root is compromised. Provider + TLS are the trust root by design. Independent signed provenance/authenticity remains an inherited deferral explicitly sourced to canonical greenfield-install PRD v2 §3, matching the already documented install.sh sidecar boundary. No stronger supply-chain claim is made. Codex security review's initial HIGH/CWE-494 finding is retained as the named trust-root deferral rather than bypassed or silently reclassified.

-
-IDENTITY / SCOPE
-- predecessor head: 0e2eef1c1261444b83c089df6047a2a06592d5c6
-- branch: feat/1050-install-state-machine-red-fixture
-- only open requirement: pipeline-level expected-case/executed-case set equality
-- unchanged/fenced: tools/fixtures/greenfield-expected-red.tsv, tools/verify-greenfield-expected-red.sh, #869, P6 detector/producer, absolute-P3 CLI linking, and per-case fixture dispositions
-- status language: believed-fixed, pending jarvis validation
-
-STALE-RULING WITHDRAWAL HONOURED
-Requirements 1-3 were withdrawn after pipeline 2242 at 0e2eef1c reached terminal green and showed P6 failure propagation, absolute-P3 CLI use, and an executed git-absent arm. A temporary local P6-consumer edit made while the stale ruling was in flight was restored before this change set; tools/e2e-install-test.sh has no final-tree delta. Requirement 5 alone remains in this round.
-
-RED-FIRST
-Before the change, .woodpecker/greenfield-install.yml had no pipeline-level initialized marker store, no per-case success marker, and no final exact-set gate. A static assertion for a final run-on-failure case-coverage step failed. Pipeline 2242's green result proved that all three cases ran once, but no gate required that population on a later run.
-
-IMPLEMENTATION
-- tools/verify-greenfield-case-coverage.sh is a new pipeline-level instrument; the existing per-case verifier is unchanged.
-- Expected case names are derived from the first TSV field of tools/fixtures/greenfield-expected-red.tsv and sorted uniquely. There is no literal expected count.
-- Marker storage is scoped by ${CI_PIPELINE_NUMBER}-${CI_WORKFLOW_NUMBER}. The init action validates the manifest and empties only that run directory, so stale markers cannot satisfy a retry or later run.
-- Every case/contract step explicitly depends on initialization. Each unconditional case step calls mark only after its exact tools/verify-greenfield-expected-red.sh invocation succeeds.
-- The final greenfield-case-denominator step explicitly depends on all four case/contract steps, has status eligibility [success, failure], emits cases_defined=N cases_executed=M, and compares sorted expected and actual case-name sets. Missing or unexpected names fail even when the two counts are equal.
-- A newly defined manifest case changes the expected set automatically and fails until a corresponding successful case step marks it.

-CURRENT-HEAD FIXTURE MEASUREMENTS TAKEN BEFORE THE STALE RULING WAS WITHDRAWN
-These measurements were run from 0e2eef1c before requirement 5 changed only pipeline instrumentation. They are retained as measured outcomes, not as justification for modifying requirements 1-3.
-- next checkout/git-present: fixture rc=1; resolved @next=0.0.50-next.2207; P0/P1/P2/P3/P7 PASS; P4/P5/P6/P8/P9 FAIL; installer_exit=1; done_claims=0; P6 reason was dead enforcement hooks active count=2.
-- next checkout/git-absent: fixture rc=1; P0/P6/P7 PASS; P1/P2/P3/P4/P5/P8/P9 FAIL; installer_exit=1; done_claims=0.
-- /home free before the first run: 8.5G; after concurrent authorized fleet reclaim completed: 11G; no be-coder-05 generated payload was deleted because active fixture work made that churn.
-
-INDEPENDENT REVIEW CYCLE
-- Initial Codex code review: REQUEST_CHANGES, confidence 0.96; one blocker found that the first draft omitted depends_on ordering and could race initialization/final checking.
-- Disposition: accepted. Added explicit init -> all case/contract steps -> final dependency graph and a regression assertion for every dependency edge.
-- Initial Codex security review: risk NONE, confidence 0.94, zero findings. The sandbox could not create its own temp directory; local focused/full tests provide the dynamic evidence.
-- First post-dependency code re-review: REQUEST_CHANGES, confidence 0.99; the case extractor treated the production manifest's comment lines as case names, while the synthetic test omitted comments.
-- Disposition: accepted. Case derivation now excludes blank/comment lines; the focused test includes representative comments and executes init/mark/check against the repository's real manifest.
-- Post-dependency security re-review: risk NONE, confidence 0.96, zero findings.
-- Final Codex code re-review after the comment fix: APPROVE, confidence 0.94, 8 files, zero findings. It confirmed ordering, run scope, fail-closed set equality, PRD alignment, and negative controls.

-#1050 C1 ROUND 5 — ARM COVERAGE + CHECKOUT PURITY
-
-IDENTITY / SCOPE
-- predecessor head: f33bd0da96bee3ce518744d6888d018bebb1c841
-- branch: feat/1050-install-state-machine-red-fixture
-- review inputs: be-coder-06 review 110; rev-security-02 review 111
-- in scope: exact required pipeline-arm set including greenfield-remote-installer-contract; success-only arm marks; skipped-remote RED control; coverage-state exclusion from checkout source archives
-- unchanged/fenced: tools/fixtures/greenfield-expected-red.tsv, tools/verify-greenfield-expected-red.sh, tools/e2e-install-test.sh, #869, and all per-case dispositions
-- status: believed-fixed, pending jarvis validation
-
-RED-FIRST — FOUR ARMS WERE REPRESENTED BY THREE CASES
-The f33bd0d gate represented only the three expected-RED case identities. With all three case names marked and no remote-arm identity available, the production checker returned:
-  SKIPPED_REMOTE_ARM_CURRENT_GATE_RC=0
-  [fixture-suite] cases_defined=3 cases_executed=3
-The fourth required arm, greenfield-remote-installer-contract, reused next-git-present and therefore could skip without changing case-set equality.
-
-RED-FIRST — COVERAGE STATE CONTAMINATED CHECKOUT ARCHIVES
-The f33bd0d workflow created .greenfield-case-state in the shared repository before the checkout-mode fixture arms. An independent reproduction using the exact e2e-install-test.sh tar exclusions created .greenfield-case-state/remote-arm.ran and measured:
-  OLD_STATE_ARCHIVE_MATCHES=1
-The state instrument was therefore part of the checkout source payload it was intended only to observe.
-
-IMPLEMENTATION
-- Renamed the checker to tools/verify-greenfield-execution-coverage.sh and generalized it over two validated dimensions: cases and arms.
-- Added tools/fixtures/greenfield-expected-arms.txt as the explicit required arm set:
-  greenfield-git-present
-  greenfield-main-git-present
-  greenfield-remote-installer-contract
-  greenfield-git-absent
-- Expected cases remain derived from the unchanged expected-RED TSV. Expected arms are derived from the new one-name-per-line arm declaration. Both inputs allow comments/blanks and validate every resulting name.
-- Each of the four fixture arms writes its unique arm marker only after its exact per-case verifier succeeds. The three distinct expected-RED cases continue to write case markers after successful verification.
-- The final step checks both dimensions even when the first check fails, emits both denominators, and fails unless both exact name sets match.
-- Coverage state moved to .mosaic-test-work/greenfield-execution-coverage/${CI_PIPELINE_NUMBER}-${CI_WORKFLOW_NUMBER}/{cases,arms}. The checkout archive already excludes every */.mosaic-test-work subtree.
-- The expected-RED manifest, per-case verifier, and detector are untouched.
-
-MEASURED SKIPPED-REMOTE CONTROL
-With all three cases marked and only the three non-remote arms marked:
-  case gate rc=0
-  [fixture-suite] cases_defined=3 cases_executed=3
-  arm gate rc=1
-  [fixture-suite] arms_defined=4 arms_executed=3
-  [fixture-suite] missing_arm=greenfield-remote-installer-contract
-This is the discriminating control: the case denominator remains green while the arm denominator catches the exact previously invisible skip.
-
-OTHER DYNAMIC CONTROLS
-- missing case: cases 3/2 => rc1
-- case count inflation (one missing + one unexpected): cases 3/3 => rc1
-- stale case markers after re-init: cases 3/0 => rc1
-- exact case set: cases 3/3 => rc0
-- future manifest case: cases 4/3 => rc1
-- arm count inflation (remote missing + unexpected): arms 4/4 => rc1
-- exact arm set: arms 4/4 => rc0
-- production expected-RED manifest comments/blanks: accepted; exact set 3/3 => rc0
-- archive selector firing control: a non-excluded root marker is present in the archive
-- archive purity control: no .mosaic-test-work path is present in the archive
-
-STATIC / STRUCTURAL CONTROLS
-- every case mark follows that arm's successful per-case verifier
-- every arm mark, including the remote contract, follows that arm's successful per-case verifier
-- all four arms depend on coverage initialization
-- final denominator depends on all four arms and is eligible after success or failure
-- final denominator runs both checks and aggregates their statuses
-- workflow contains the already-excluded .mosaic-test-work state root and no .greenfield-case-state reference

-# #1050 C1 fix round — Round 6 caller coupling and production archive binding
-
-BASE HEAD
-- df705828a439c6795cd47c938ed7f838b956ebf3
-- Reviews 114 (rev-security-02) and 115 (be-coder-06) independently reproduced the same caller-level mutant: ignoring arms_status in the workflow left the focused helper suite green.
-- Both reviewers confirmed the production aggregation was correct and requested test reachability, not a logic rewrite.
-- rev-974 separately deleted only the production e2e-install-test.sh .mosaic-test-work tar exclusion; the copied-selector suite remained green.
-
-RED
-- After adding the four-cell caller truth-table expectations but before creating the workflow helper:
-  bash tools/verify-greenfield-execution-coverage.test.sh => rc=1
-  The expected helper did not exist, so the test could not reach a passing aggregation implementation.
-- Prior independent controls:
-  ignore-arms workflow mutant => rc=0 before this round (reviews 114/115)
-  delete-production-archive-exclusion mutant => rc=0 before this round (rev-974 exact-head sandbox)
-
-IMPLEMENTATION
-- Extracted the existing set +e / two checks / status capture / final OR into tools/verify-greenfield-execution-coverage-gate.sh without changing its semantics.
-- .woodpecker/greenfield-install.yml now invokes that helper directly; its inline duplicate was removed.
-- The focused suite invokes the same helper used by the workflow across all four cells:
-  cases PASS / arms FAIL => RED
-  cases FAIL / arms PASS => RED
-  both FAIL => both diagnostic outputs and RED
-  both PASS => GREEN
-- The archive-purity test now first locates the production checkout-archive command in tools/e2e-install-test.sh and requires its .mosaic-test-work exclusion, then proves the exclusion's archive effect.
-- GREENFIELD_COVERAGE_GATE and GREENFIELD_E2E_INSTALLER are test-only subject injection seams used to prove the requested mutants; production paths remain the defaults.

-- Review 119 (rev-974) found tools/verify-greenfield-execution-coverage.sh used GNU-only find -printf.
-- Pipeline 2246's canonical Alpine ci-base test failed while the Debian greenfield workflow passed; the stale pipeline is diagnostic evidence only and is not inherited as a ruling for the replacement head.

-
-BASE HEAD
-- 58ada98d2b430da28c46cf92eebdb6d45b8b1846
-- Review 122 (rev-security-02) found expected_names | grep -Fxq could falsely reject valid markers under pipefail when grep closed the pipe after an early match and the producer exited 141.
-- Independent canonical-Alpine live-manifest stress reproduced intermittent false failures at the current four-arm set size. No small-manifest safe threshold is claimed.
-
-DETERMINISTIC RED
-- The focused suite now generates a 20,001-name manifest with a valid target sorted first and invokes the real mark path.
-- Before remediation, in canonical Alpine ci-base:

-Frozen reviewed head before remediation: `378bc1afe3bc485adb8614897d66c5edccd4a527`.
-
-Status: **believed-fixed, pending jarvis validation**. PR #1054 is not self-merged and issue #1050 remains open.
-
-## Blocker B — fail-closed test enumeration
-
-The RED-first control used a real filesystem permission failure, not binary shadowing or PATH interception.
-
-1. A planted `{"status":"in-progress"}` file in a readable P2 fault tree made the complete real walk fail the frozen suite at `P2 left an in-progress transaction` (`01-pre-fix-positive-control.log`, exit 1).
-2. The same planted defect beneath a target-owned mode-0100 directory made real `find` report a permission failure. The frozen suite erased the producer failure and exited 0 with `installer next lane tests passed` (`02-pre-fix-permission-failure-attack.log`).
-3. The committed regression control initially failed because the child full-suite attack still exited 0 (`03-regression-test-red.log`).
-4. After remediation, the same child full-suite input exits 1 and names `[test] ERROR: P2 fault-state enumeration failed` (`04-post-fix-permission-failure-attack.log`). The ordinary full suite remains green.
-
-`tools/test-enumeration-assertions.sh` now captures each complete NUL-delimited population and checks the producer status before asserting absence. Content checks inspect the captured population and distinguish “no match” from a read error. The shared fail-closed implementation covers:
-
-- `tools/install-next-lane.test.sh`: redacted staging-file cleanup and fault-state transaction scan;
-- `tools/verified-installer-fetch.test.sh`: temporary-download cleanup;
-- `tools/install-state-machine.test.sh`: symlink-target non-mutation;
-- `docs/reports/verification/1050-b8-redaction-control/positive-control.test.sh`: both copied counterparts.
-
-No assertion was loosened. A1, A2, upgrade-guard, source-root, the species-2 sweep, #869, and expected-RED verdict rows remain outside this remediation.
-
-## Blocker A — installer digest
-
-The stale sidecar value was replaced with the exact `sha256sum` record for `tools/install.sh`:
-
-```text
-e59cb441a2f37ae9150f8eae470238e9d858a1816df93343d9784a6796676096  install.sh
-```
-
-RED-first documentation control from the repository root: `sha256sum -c tools/install.sh.sha256` exits 1 with `install.sh: FAILED open or read` because the sidecar records a path relative to `tools/`. The command actually executed, `(cd tools && sha256sum -c install.sh.sha256)`, exits 0 with `install.sh: OK`; the workflow's separate exact expected/actual equality also passes. The immutable provider-fetch arm at the new `${CI_COMMIT_SHA}` is recorded in the freeze artifact after push; local equality alone is not treated as sufficient evidence.
