-## 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.
-9. Unsupported musl/Alpine and unavailable Docker SHALL fail loudly rather than skip as pass. The repository's installer tests SHALL nevertheless run in the canonical Alpine CI image by explicitly modeling a supported non-root/glibc target and using portable filesystem enumeration.
-10. P0 SHALL bind the effective uid and username to the authoritative passwd HOME and shell and state/reject unsafe root or sudo-with-inherited-HOME privilege contexts.
-11. Created paths SHALL satisfy phase-specific target owner/group and mode policy: P3 executables are not group/world writable, framework/runtime trees are not group/world writable, and identity/credential material is private.
-12. The expected-RED comparator SHALL validate the complete manifest before selecting a case: exact case population, one exit and P0–P9 disposition per case, pinned require/forbid classes, and no malformed, duplicate, or unknown rows.
-13. The published installer contract SHALL reject failed fetches, HTTP-success empty bodies, and digest mismatch, then execute the exact digest-verified body. The remote CI arm SHALL enumerate every payload-acquisition path and report a bound/found denominator. It SHALL bind both the installer body and the downstream stack framework/source it consumes to the same immutable CI commit, while retaining `--next` as the lane selector. 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.
-14. Phase diagnostics SHALL be redacted before terminal or durable-log output. A seeded positive-control canary SHALL remain absent from observed argv, output, command logs, npm configuration, generated files, and shell history.
-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.

-## 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.

- predecessor/provider lease pin: ff3f0d29f1763bed44a60610d073036112e66b77
- status language: believed-fixed, pending jarvis validation
- in scope: remote arm's mosaicstack/stack framework/source archive (#7)
- unchanged/fenced: expected-RED manifest including P6=FAIL; #869; #1068 sequencing
- corrected reference citation: the container-image acquisition path in fa-install.sh only
-
-ACQUISITION-PATH CENSUS (10/10 CODE-READ; COMPLETE RUNTIME PATH CENSUS NOT MEASURED)
-1. Woodpecker checkout at CI commit — fully constrained by intended CI identity.
-2. node:22-bookworm-slim image — unpinned sibling, out of scope.
-3. apt package set — unpinned sibling, out of scope.
-4. tools/install.sh at CI_COMMIT_SHA + verified SHA-256 — fully constrained.
-5. @mosaicstack/mosaic@next — P2 CLI value is authoritative; realised disagreement is detected at P3 — fully constrained at the top-level package version.
-6. @mosaicstack/gateway@next — later re-resolution wins and is verified against itself; drift from the first value can be silently accepted — partially constrained TOCTOU sibling, out of scope.
-7. stack framework/source archive — pre-fix internally pinned to WRONG identity 4df478cdd150fdf8d52ea109f02ade5d85017acd; post-fix bound to intended CI commit.
-8. unversioned sequential-thinking npx package — unpinned sibling, out of scope.
-9. Excalidraw dependency graph — shipped lockfile exact versions + registry integrity hashes — fully constrained by lock/integrity.
-10. agent-skills default-branch clone — unpinned sibling, out of scope.
-
-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.
-
-#5/#6 RESOLUTION-FAILURE / TOCTOU DISPOSITION (CODE-READ; DISAGREEMENT INJECTION NOT MEASURED)
- 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.

-IMPLEMENTED PATH #7
- .woodpecker/greenfield-install.yml supplies MOSAIC_FIXTURE_SOURCE_COMMIT=${CI_COMMIT_SHA} while still invoking --lane next and --source remote.
- tools/e2e-install-test.sh validates 40-hex commit input, derives the exact commit archive URL, rejects failed/empty fetch, computes SHA-256 over that exact body, and passes the body/commit/digest through MOSAIC_INSTALL_LOCAL_SOURCE_{ARCHIVE,COMMIT,SHA256}.
- The existing installer local-source seam re-hashes the body and rejects mismatch.

- 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.

-#1050 C1 ROUND 4 — PIPELINE CASE-COVERAGE DENOMINATOR
-
-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.
-
-MEASURED CONTROLS
-1. Skipped expected arm:
-   rc=1
-   [fixture-suite] cases_defined=3 cases_executed=2
-   [fixture-suite] missing_case=next-git-absent

-   missing_case rows emitted for all three expected names

-CURRENT-HEAD FIXTURE MEASUREMENTS TAKEN BEFORE THE STALE RULING WAS WITHDRAWN

-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.

-# #1050 C1 fix round — Round 7 canonical Alpine/BusyBox portability
-
-BASE HEAD
- d66e91b1f22489b911eef982aec3faa62c5edeb3
- 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.
-
-RED
- Before remediation:
-  docker run --rm -v "$PWD:/workspace" -w /workspace git.mosaicstack.dev/mosaicstack/stack/ci-base:latest bash tools/verify-greenfield-execution-coverage.test.sh
-  => canonical_alpine_red_rc=1
- Independent review 119 captured BusyBox 1.37 rejecting `find: unrecognized: -printf`.
- Debian/GNU execution remained green, proving that one runtime's success did not establish portability.
-
-IMPLEMENTATION
- Removed the GNU find -printf inventory.
- Marker inventory now uses Bash nullglob/dotglob plus parameter expansion, all available in the script's declared Bash runtime.
- The checker verifies the run directory is readable/searchable before inventory and fails closed otherwise.
- Only direct regular, non-symlink `*.ran` files are included, preserving the prior find boundary; identities remain sorted and compared as exact sets.
- No production fixture disposition, expected-RED manifest, e2e installer, #869 wiring, or acquisition behavior changed.
-

-# #1050 C1 fix round — Round 8 pipefail-safe expected-set membership
-
-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:
-  docker run --rm -u "$(id -u):$(id -g)" -v "$PWD:/workspace" -w /workspace git.mosaicstack.dev/mosaicstack/stack/ci-base:latest bash tools/verify-greenfield-execution-coverage.test.sh
-  => canonical_sigpipe_tdd_red_rc=1
-  => [fixture-suite] case is not in the expected set: a-target
- This control exercises the production checker invocation rather than an approximated producer and makes the early-close race deterministic by exceeding pipe capacity.
-
-IMPLEMENTATION
- The mark path now fully materializes expected_names into expected_snapshot and fails closed if production fails.
- grep -Fxq reads the completed snapshot through a here-string; there is no producer/consumer pipeline to close early.
- Missing names still fail with the same attributable message. No `|| true` or other failure suppression was introduced.
- Exact-set checks, marker inventory, aggregation, archive binding, fixture dispositions, expected-RED manifest, e2e installer, #869 wiring, and acquisition behavior are unchanged.
-
-GREEN
- Local focused suite: greenfield execution coverage tests passed.
- Canonical Alpine focused suite: greenfield execution coverage tests passed.
- Canonical Alpine live production-manifest stress: 1,000 valid greenfield-git-absent arm marks, failures=0.
- Canonical grep-q pipeline mutant through the real checker path => rc=1 with the attributable false rejection; restored subject => GREEN.
- Existing Round-6 controls retained:
-  ignore-arms aggregation helper => rc=1
-  ignore-cases aggregation helper => rc=1
-  always-RED aggregation helper => rc=1
-  delete production .mosaic-test-work archive exclusion => rc=1

-# #1050 C1 fix-round verification
-
-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

-```
-
-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.

-## Required artifacts
-
- [x] `docs/PRD.md` exists; #1050 C1 requirement 13 binds the complete in-scope remote stack source chain, and requirement 15 binds exact case+arm execution coverage, executable aggregation, production-bound archive purity, dual-runtime portability, and pipefail-safe materialized membership.
- [x] User guide: not applicable; no user-facing production installer behavior changed.
- [x] Admin guide: not applicable; no operator procedure or deployment behavior changed.
- [x] Developer guide: existing `docs/guides/installer-state-machine.md` defines the fail-closed installer model; the C1-specific remote-arm contract and evidence live in the PRD, scratchpad, and scoped verification report.
- [x] OpenAPI and endpoint index: not applicable; no API changed.
- [x] Sitemap: not applicable; no navigation changed.
-
-## API and structural coverage
-
- [x] API schema/auth/error coverage: not applicable; no endpoint changed.

-## Review and publishing
-
- [x] Verification documentation is in the same logical change set as the shell-test remediation.
- [x] Trust boundary states both halves: the digest proves fetched bytes remain identical through execution/verify-after; it does not authenticate authorship against provider/TLS compromise. Independent provenance is the inherited PRD v2 §3 deferral.

-# #1050 successor remediation verification
-
-Head under test before remediation: `e5d5c8495a070af2dcd393cace287fe74a8a819e`.
-
-This change strengthens the expected-RED detector; it does not repair the intentionally failing greenfield rows. The #869 hooks remain unwired.
-
-## A1 — P0 reason binding
-
-RED first:
-
-```text
-$ bash tools/verify-greenfield-expected-red.test.sh
-[test] FAIL: vacuous P0 PASS satisfied the expected-RED contract without identity/context evidence
-exit=1
-```
-
-The pinned manifest now has an explicit `phase-reason` binding against the final P0 row: target `mosaic`, uid `1001`, equal `HOME` and passwd HOME, `/bin/bash`, `privilege=user`, `x86_64`, glibc, and version-shaped Node/npm evidence. All three cases structurally require exactly one P0 reason binding. The greenfield fixture's final P0 row now emits and validates the same complete identity/context evidence, so an unrelated earlier P0 line cannot satisfy the binding for a vacuous final row.
-
-Pipeline 2224 and the successor's pre-change fixture run also exposed a stale next-lane P6 reason left behind by the already-closed B6 remediation: actual behavior is a fail-closed runtime-link action refusal with `#869` hooks left inactive and a persisted required P6 failure, while the manifest still expected dead hooks to be active. The pinned reason now matches the stronger measured refusal (`runtime linking/activation action reported a required failure`); no verdict changed and #869 remains unwired.
-
-GREEN:
-
-```text
-[test] PASS: P0 PASS must bind target identity, HOME, shell, privilege, architecture, and runtime reason
-```
-
-## A2 — fail-closed P4 enumeration
-
-RED first: a `find` control emitted only the safe root, omitted an unsafe mode-`0666` child, and exited `73`. The process-substitution consumer discarded that status:
-
-```text
-[test] FAIL: P4 accepted a partial created-path inventory after find failed
-[test] FAIL: P4 did not report failed created-path enumeration
-exit=1
-```
-
-P4 now captures the NUL-delimited walk into a temporary file, checks `find` to completion, and only then evaluates the complete inventory. A failed walk reports that enumeration failed and returns a P4 finding.
-
-GREEN:
-
-```text
-[test] PASS: P4 rejects an incomplete created-path inventory
-[test] PASS: P4 attributes the failed created-path enumeration
-```
-
-## B — deterministic TERM no-exit control
-
-Woodpecker pipeline 2224 at the original head reported `32 passed, 2 failed`: the no-exit fixture did not exit zero or report sync success. The premise was not stale: the same fixture passed `34/34` on another filesystem.
-
-A controlled reverse-sorted `find -print0` walk reproduced the pipeline result exactly (`32 passed, 2 failed`). Root cause: signal injection was tied to `guides/E2E-DELIVERY.md`; whether required `tools/` content remained after restore depended on filesystem enumeration order. The test was measuring path order as well as trap semantics.
-
-The generated fixtures now damage a real target path after the snapshot is armed, self-signal immediately before the complete normal sync, and differ only in the explicit handler exit. Therefore a no-exit handler always restores, returns, runs the full sync, mutates the restored target again, and reports completion independent of walk order.
-
-GREEN on both native and reverse-sorted enumeration:
-
-```text
-RESULT: 36 passed, 0 failed
-```
-
-Mutation sensitivity: restoring `exit 1` to the nominal no-exit fixture makes the control RED (`32 passed, 4 failed`), including failures of the zero-exit and resumed-success assertions. The control can still fail for its stated reason.
-
-## Enumeration-class sweep
-
-The sweep covered production enumeration in `tools/install.sh` and `packages/mosaic/framework/install.sh`, plus process-substitution consumers in the C1 shell-test surfaces. Framework installer file, operator, durable-snapshot, and pruning walks already capture and check their producer status. P4's created-path walk was the reviewed unchecked instance.
-
-One additional order/completeness dependency was found in source acquisition: `find "$WORK_DIR" ... | head -1` hid `find` failure and selected arbitrarily when an archive produced multiple top-level directories. RED first, the extraction fake produced two roots and the lane test stopped at that new assertion with exit 1 because today's code selected one. Source acquisition now captures and checks the complete NUL-delimited walk and requires exactly one extracted root. The lane suite is green with the multiple-root rejection. No remaining production installer enumeration uses unchecked process substitution or first-row order as authority.

-# #1050 — Installer P0–P9 state machine and red-first fixture
-
-## Objective
-
-Implement C1 from the canonical greenfield-install PRD v2: a transactional P0–P9 installer spine, a side-effect-free P0–P8 `--check`, and a lane-parametric Debian/glibc non-root from-zero fixture. The acceptance milestone is an attributable RED on the pre-C1 installer while preserving P3 PASS.
-
-## Authority and scope
-
- Canonical requirements: `jason.woltje/jarvis-brain` `docs/plans/2026-08-04-greenfield-install-blockers-PRD-v2.md`. Currency was re-derived after compaction: authenticated fetch resolved `origin/main` to `cb23e5fbc8a282fa967b93d7a134fa48d11b4bb1`; the PRD and charters are byte-identical to the previously read remote copies.
- Tracking: `mosaicstack/stack#1050` on `git.mosaicstack.dev` (author read back as `be-coder-05`).
- Historical implementation base: `origin/next` `4df478cdd150fdf8d52ea109f02ade5d85017acd`. Delivery PR #1054 targets `main` under L0's trunk-only rule; `next` remains a non-merging integration lane.
- Out of scope: PATH, skills, headless wizard/identity, activation remediation, #869 wiring, RM-02, main promotion.
- `docs/TASKS.md` is orchestrator-single-writer and is not modified by this worker.
-
-## Plan
-
-1. Pre-register the canonical phase/output/side-effect-free/fault-injection checks and observe RED against the base installer.
-2. Commit the immutable red-first acceptance fixture before implementation.
-3. Add the state-machine/journal/postcondition spine without repairing P4/P5/P8 symptoms.
-4. Wire the expected-RED from-zero fixture into Woodpecker using Debian/glibc and a non-root target user.
-5. Run shell/static baselines, situational container validation, code review, security review, then deliver through a PR to `next` under the coordinator-owned merge path.
-
-## Budget
-
- Working estimate: 32K reasoning/output tokens.
- Hard external cap: none stated.
- Adaptation: keep implementation in shell surfaces already in scope; no package dependency install unless repository gates require it.
-
-## Pre-registered acceptance checks
-
-| ID | Exact case | Expected pre-fix result |
-|---|---|---|
-| C1-R1 | `tools/e2e-install-test.sh --lane next` in a clean Debian 12 container as uid 1001 | non-zero; P3 PASS; P4 `NOT-MEASURED / UNDECLARED`; P5/P6/P8 FAIL with own reasons |
-| C1-R2 | `tools/install-state-machine.test.sh` phase table case | RED because base installer does not enumerate canonical P0–P9 contracts |
-| C1-R3 | side-effect-free `--check` case over a fingerprinted HOME | RED because base `--check` is version-only rather than P0–P8 predicates |
-| C1-R4 | fault injection after each P2…P8 | RED because base installer has no injectable durable journal/rollback state |
-| C1-R5 | Docker unavailable | base harness incorrectly exits 0; replacement must fail non-zero |
-| C1-R6 | lane resolution | bare checkout is forbidden; fixture must pass `--next` and assert the resolved prerelease version |
-| C1-R7 | same Debian fixture with `git` absent vs present | absent: P1 FAIL while legacy installer exits 0 and sync degrades; present: P1 PASS and observed store/runtime containment 101/101 |
-
-## Progress
-
- [x] Charter, doctrine, delivery/CI/QA/docs guides read and re-anchored after compaction.
- [x] Canonical PRD v2/v3 addenda and charters read from fetched `origin/main`; numbering reconciles with the TL spec. No numbering conflict found. INV-B/C/D are binding and implemented without renumbering.
- [x] Target base reachability verified with `merge-base --is-ancestor`.
- [x] Issue #1050 created and provider author read back.
- [x] Initial RED captured; TL rejected P4's repo-root count as a false RED. Four populations disagree (framework payload 1, repo root 13, sync store 101 in the fixture, W-jarvis observation 7), so C1 now requires a checkout-free declared shipped-set artifact and reports P4 `NOT-MEASURED / UNDECLARED` until C5 supplies it.
- [x] P6 strengthens #869: the two dead enforcement hooks reproduce from zero on a clean broker-less container. C1 asserts the breach but neither wires nor unwires it.
- [x] P1 false pass identified from the P4 evidence row: `git` is absent from the Debian base and was undeclared even though skill sync shells out to it. C1 adds `git` to P1; the fixture matrix preserves absent/present controls. The prior claim that web1's missing runtime skills reproduce this greenfield mechanism is withdrawn by the TL and is not carried here.
- [x] Corrected RED transcript captured and reported, including the git-present/absent controls and strict P3 PASS.
- [x] State-machine implementation complete: private pre-mutation journal/snapshot, P0–P8 `--check`, P2–P8 fault seam, rollback, durable manifest/journal seal, action-status persistence, safe rollback roots, and stale-projection recovery.
- [x] Debian/glibc checkout fixture now packages the complete current checkout, verifies its digest in-container, and reaches the expected attributable RED without host inheritance. CI compares its exact final phase map/reasons to `tools/fixtures/greenfield-expected-red.tsv`; the fixture remains red while the detector job is green only on an exact match.
- [ ] Reviews complete. Reviews 80 (`rev-security-02`) and 81 (`rev-974`) requested changes at `3934e03f`; their eight non-overlapping detector findings are being remediated red-first. Current remediation adds canonical-image portability, absolute P3 CLI propagation, exact expected-RED schema/cardinality, passwd-HOME binding, created-path owner/mode policy, real-action P2–P8 fault injection, verified non-empty remote installer execution, and seeded secret-canary/redacted diagnostics. Both old verdicts become void when the remediation head moves and require fresh independent review.
- [x] Successor remediation for review 90 is RED-first and recorded in `docs/reports/verification/1050-successor-remediation/`: the manifest now binds the complete supported final P0 reason; P4 rejects an incomplete created-path walk instead of discarding `find` failure; and the TERM no-exit control is independent of filesystem enumeration order while retaining a proven RED mutation. Pipeline 2224's 32/2 result was a path-order-sensitive control, not evidence that the resume bug's premise became stale. The enumeration-class sweep additionally replaced order-dependent `find | head -1` source-root selection with a checked complete inventory requiring exactly one extracted root.
- [x] C1 fix round for reviews 92/93: Blocker B was completed first. RED was reproduced before implementation: a planted `{"status":"in-progress"}` record makes the complete real walk fail the suite at P2, while the same planted defect beneath a target-owned mode-0100 directory makes real `find` fail and the frozen suite falsely exit 0 with `installer next lane tests passed`. One shared helper now captures and checks the complete NUL-delimited population before testing absence across the primary and copied harness sites; grep no-match is distinct from read failure. The same attack child drives the full suite RED with a named enumeration error, while ordinary native and root/container runs pass. Blocker A then regenerated the exact installer sidecar; provider-fetch validation remains the required post-push bar. Working estimate: 16K tokens; no external hard cap; 60% context is the stop/report gate.
-
-## Risks / blockers
-
- The deployed create wrappers do not expose `--dry-run`; identity preflight was performed through `pr-merge.sh --dry-run` on the same HOMELAB repo, which resolved `git.mosaicstack.dev` + `be-coder-05`. The issue create then fell back from tea to the API but provider read-back confirmed author `be-coder-05`.
- `next` is a non-merging integration lane; PR #1054 targets `main`. The old “pending promotion to main” caution dissolved when the base moved. #1050 remains open after merge and closes only after Jarvis validates the greenfield behavior.
- #869 must remain staged and inactive.
- Late sequencing input MB-BRAIN-01 is accommodated without implementation or renumbering: P2 covers installer distribution only; P5 owns requested credential capability; P7 leaves an ordered seam for credential-dependent resource provisioning after P5.
-
-## Remediation review controls
-
- B1 RED: the next-lane harness failed immediately under `ci-base:latest` as root/musl; it now models uid 1001/glibc explicitly and uses Python tree fingerprints instead of GNU `find -printf`.
- B2 RED: framework/runtime linking consumed bare `mosaic` from PATH after P3 had committed an absolute path. The unified installer now exports/passes `MOSAIC_CLI_PATH`; the linker invokes that absolute artifact, and wizard auto-launch has no stale-PATH fallback.
- B3 RED: a one-row manifest (`exit=1`) certified any exit-1 log. Full-manifest validation now requires the exact three cases, one exit and P0–P9 row each, pinned require/forbid populations, and rejects malformed/duplicate/unknown rows; shrink is a negative control.
- B4 RED: uid 1001 with a passwd HOME different from ambient HOME produced P0 PASS. P0 now binds uid, username, passwd HOME and shell and explicitly rejects root and sudo-with-inherited-HOME controls.
- B5 RED: mode-0777 CLI, mode-0644 identity, and mode-0755 credential storage passed. P3/P4/P5 now apply target owner/group plus executable/shared/private policies; framework credential storage is created 0700.
- B6 RED: fault injection only wrote `.selftest-*` files. The synthetic path was removed; the P2–P8 matrix enters the normal action flow, proves an action observation occurred, injects after each real phase, and fingerprints rollback.
- B7 RED: an HTTP-200 empty body exits zero when piped to Bash. The fetched installer must now be non-empty, digest-equal to `tools/install.sh.sha256`, and that exact file is executed; failed/empty/mismatch controls are blocking and CI has a remote immutable-commit arm.
- B8 RED: raw combined command output was duplicated to terminal and `commands.log`. Both capture layers now redact before output/persistence; a seeded canary is positively emitted by the fake credential-capable registry and must remain absent from terminal, command log, npmrc, generated files and observed argv. The real greenfield fixture also scans those populations.
- Advisory code review findings are fixed: URL userinfo redaction now handles raw `@`, token-only and percent-encoded forms, repeated `:`, multiple URLs, Authorization/Basic, npm `_auth`, and Cookie headers in both capture layers; the real greenfield path positively emits its canary through `state_run_captured`; verified-fetch removes its temporary body after successful execution; and plaintext diagnostics exist only in process-substitution pipes rather than interruptible temporary files.
- Advisory security review's independent trust-root finding is **DEFERRED by canonical PRD v2 §3**, which explicitly excludes signed provenance. README now states precisely that the same-origin sidecar detects empty/corrupt/inconsistent publication but cannot authenticate against repository/server compromise; no stronger claim remains.
- The web1 no-manifest representativeness observation is recorded but intentionally not acted on: it is explicitly outside these eight blockers. This remediation does not weaken or otherwise change P9's manifest-presence assertion.
-
-## Verification log
-
- `bash -n` and ShellCheck pass for all changed shell surfaces; `git diff --check` passes.
- `bash tools/install-state-machine.test.sh` passes, including exact P0–P8 rows, passwd-HOME/privilege discrimination, owner/group/mode attacks, persisted P4/P6 action failures, no synthetic fault implementation, unsafe/overlapping/symlink roots, and fatal journal initialization.
- `bash tools/install-next-lane.test.sh` passes inside `ci-base:latest`, including exact `@next` versions, immutable source fallback, source-build/archive-failure rollback, offline `--dev`, explicit refs, prerelease suffix mismatch, absolute P3 CLI propagation, secret redaction, real-action P2–P8 rollback, and stale projection recovery.
- Comparator controls pass for verdict drift, unexpected exit, manifest shrink, missing phases, duplicate rows, unknown cases, and unknown kinds. Verified-fetch controls pass for successful execution and failed/empty/digest-mismatch rejection.
- `bash tools/e2e-install-test.sh --lane next --source checkout --git present` returns the required expected RED in clean Debian/glibc as uid 1001: installer P0/P1/P2/P3/P7 PASS; P4/P5/P6/P8 and P9 blocking; no `Done.` claim; checkout archive digest pinned and current framework installer exercised. `tools/verify-greenfield-expected-red.sh` converts that expected detector result into a green CI assertion and fails on any unreviewed verdict drift.
- Earlier repository gates passed: `pnpm typecheck`, `pnpm lint`, `pnpm format:check`, upgrade manifest/rollback/durable-snapshot/migration suites, and focused `@mosaicstack/mosaic` tests with an isolated npm prefix. Full exact-remediation rerun is required before push.
- Review-93 RED evidence at frozen `378bc1a`: isolated positive-control full-suite exit `1` with `P2 left an in-progress transaction`; isolated permission-failure attack full-suite exit `0` with final `installer next lane tests passed`. No binary shadowing or PATH interception was used; the failure came from a real target-owned mode-0100 directory.
- Fix-round GREEN: `pnpm test:installer`, native next-lane, root/`ci-base:latest` next-lane, state-machine, verified-fetch, Bash syntax, ShellCheck, `pnpm typecheck`, `pnpm lint`, `pnpm format:check`, and `git diff --check` pass. The direct attack child exits 1 and names `P2 fault-state enumeration failed`. All 81 Mosaic Vitest files / 1508 tests pass under an isolated npm prefix; the wider framework-shell chain reaches the pre-existing #973 Bash-line-number gate and exits 97, matching the known host-specific condition rather than this delta. Codex code review approved at 0.93 confidence with zero findings; Codex security review reported no risk at 0.96 confidence with zero findings.
- Sidecar 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 path is relative to `tools/`. Sidecar GREEN with the command actually executed: `(cd tools && sha256sum -c install.sh.sha256)` exits 0 with `install.sh: OK`; the workflow's separate expected/actual comparison resolves `e59cb441a2f37ae9150f8eae470238e9d858a1816df93343d9784a6796676096`. This is not substituted for the required immutable provider-fetch arm at the pushed head.
-
-## Round 3 — remote-arm downstream source binding
-
-### Objective and constraints
-
- Tracking remains `mosaicstack/stack#1050`, delivery PR #1054, branch `feat/1050-install-state-machine-red-fixture`; `docs/TASKS.md` remains orchestrator-single-writer.
- Bind the remote arm's downstream stack framework/source archive to the same immutable `${CI_COMMIT_SHA}` as the digest-verified `install.sh`, while retaining `--next` and its exact resolved CLI/gateway lane-version assertion.
- RED first: the realised source commit/digest assertion must reject the existing stale `origin/next` substitution; GREEN must restore the exact expected `P6 FAIL` and pass the comparator. R7 then deletes the binding and requires RED again.
- Fenced out: the expected-RED manifest (including `P6=FAIL`), #869 activation, and #1068 digest-before-comparator sequencing.
- Push budget: one force-with-lease push pinned to provider head `ff3f0d29f1763bed44a60610d073036112e66b77`; run the queue guard first; do not poll CI after push.
- Working estimate: 14K reasoning/output tokens; no external hard token cap. Scope reduction order: reuse the existing local-source archive seam, add one realised-state assertion, avoid installer behavior changes.

-### Corrected reference citation
-
-The transferable reference is only **the container-image acquisition path in `fa-install.sh`**: resolve mutable input once to `Docker-Content-Digest`, fail closed if unresolved, render `@sha256`, then verify running images against the resolved digest. It is not a claim about USC's installer as a whole; the sibling root bundle extraction in `Install-FieldAgentOnPanel.ps1:82` is unpinned. The applicable structure is `RESOLVE-ONCE -> PIN -> FAIL-CLOSED ON RESOLUTION -> VERIFY-AFTER`, applied per acquisition path.
-
-### Remote-arm acquisition-path census before the fix
-
-Code-path enumeration only; execution of the complete list is **NOT MEASURED** in this round yet. Logical payload paths are counted once even when one command is invoked repeatedly or installs a dependency graph.

-| # | Acquisition path taken by the arm | Pre-fix binding state | Scope disposition |
-|---|---|---|---|
-| 1 | Woodpecker checkout containing the workflow, fixture, sidecar, and comparator | CI commit checkout (commit-bound by runner contract) | existing arm substrate |
-| 2 | `node:22-bookworm-slim` step image | mutable image tag | unpinned sibling; outside this fix fence |
-| 3 | Debian package set acquired by `apt-get update/install` | repository-current, no package versions/snapshot | unpinned sibling; outside this fix fence |
-| 4 | remote `tools/install.sh` | exact `${CI_COMMIT_SHA}` URL plus checked SHA-256 | in scope; already bound first hop |
-| 5 | `@mosaicstack/mosaic@next` CLI package graph | mutable lane resolved to an exact top-level version, exact version installed, realised top-level version verified | lane assertion; must remain |
-| 6 | `@mosaicstack/gateway@next` package graph | later re-resolution wins and is verified against itself; drift from the first value can be silently accepted | partially constrained TOCTOU sibling; outside this fix |
-| 7 | `mosaicstack/stack` framework/source archive consumed by `ensure_monorepo` | `next` resolves once to `4df478cdd150fdf8d52ea109f02ade5d85017acd`, not the arm's CI commit | **in-scope defect; bind to CI commit** |
-| 8 | sequential-thinking MCP package warmed via unversioned `npx -y @modelcontextprotocol/server-sequential-thinking` | mutable package resolution | unpinned sibling; outside this fix fence |
-| 9 | Excalidraw npm dependency graph | shipped `package-lock.json` exact versions + registry integrity hashes; `npm install` consumes the lock | already lock/integrity-bound, separate from CI-source identity |
-| 10 | canonical skills repo cloned by `mosaic-sync-skills` | mutable default branch of `mosaic/agent-skills.git` | unpinned sibling; outside this fix fence |
-
-Pre-fix mechanism breakdown (do not blend unlike strengths): **2 / 10 intended-CI-commit-bound** (#1 checkout, #4 installer); **1 / 10 resolve-then-pin with comparison to the authoritative value** (#5 CLI); **1 / 10 partially constrained because verify-after compares #6 gateway to its later re-resolution rather than an authoritative pin**; **1 / 10 lockfile+integrity-bound** (#9 Excalidraw); **1 / 10 internally pinned to an immutable commit+digest but bound to the wrong arm identity** (#7 framework at `4df478cd`); **4 / 10 unpinned siblings** (#2, #3, #8, #10). The in-scope same-CI stack payload ratio is **1 / 2** (`install.sh` yes; framework/source no).
-
-Resolution-failure behavior is separately stated rather than hidden in the counts. For #5/#6, a metadata-resolution failure during P1 blocks before mutation. Later package metadata/install failure enters the documented source fallback, but that fallback consumes the immutable stack archive already resolved in P2; failure to resolve or fetch that source is fatal. For #5, the P2 CLI value is authoritative and a later realised mismatch blocks P3 and rolls back. For #6, no authoritative P2 gateway value persists; a later same-suffix gateway drift can be silently accepted because the later value is compared with itself. Changing that TOCTOU path is outside this fix. The new #7 path accepts the 40-hex CI commit directly, fetches only its exact commit URL, rejects failed/empty acquisition, computes and passes the exact body's digest through the existing local-source seam, and rejects any realised manifest commit/digest mismatch without falling back to `next`.
-
-Denominator corrections were sent to and accepted by the lane lead before implementation. Four expressly unpinned siblings make `7/10` impossible. Post-fix, the primary mechanism breakdown is **fully constrained 5 / 10** (#1, #4, #5, #7, #9), **partially constrained 1 / 10** (#6), and **unpinned 4 / 10** (#2, #3, #8, #10). The meaningful repaired ratio is **2 / 2 same-CI stack payload hops**. The fix does not increase coverage; it moves #7 from wrong identity to intended identity. Every census revision moved assurance downward under additional questioning, never upward, so the census is a lower bound on defects and an upper bound on assurance.
-
-### Implementation plan
-
-1. Add the realised source commit+archive-digest assertion and pass the expected immutable identity through the remote fixture; run the current stale-`next` mechanism and capture RED before changing acquisition.
-2. Fetch the stack archive from the exact commit URL once, fail closed on failed/empty acquisition, compute its digest, pass that exact body through the installer's existing local-source archive seam, and verify the manifest's realised `sourceCommit` and `sourceSha256` against those values.
-3. Run exact-source GREEN: require `P6 FAIL` values and a passing `next-git-present` comparator; run focused installer/baseline gates.
-4. R7: delete the binding in a temporary mutant, run the same assertion to RED, then restore and re-run GREEN.
-5. Independent code/security review, commit with command-scoped identity, queue guard, one force-with-lease push pinned to `ff3f0d29`; stop without CI polling and report `believed-fixed, pending jarvis validation`.
-
-### Executed outcome
-
- RED-first stale substitution: fixture `rc=1`; realised source `4df478cdd150fdf8d52ea109f02ade5d85017acd` / `3e6d831efe13c3b2c0501507099d4a566af5abf877dacf85e5d7e4284d35e5c7` rejected against expected `ff3f0d29f1763bed44a60610d073036112e66b77` / `944c6db1b01b23c83169e6dc83e0d31262b1d24a2825270441745eb65c269c25`; comparator `rc=1`, 8/19 mismatches.
- Exact-source reproducibility, N=5 identical final-tree executions: every run had fixture `rc=1`, `@mosaicstack/mosaic@next=0.0.50-next.2207`, P3 PASS, realised source `ff3f0d29…` / `944c6db1…`, SOURCE-CONTROL PASS, `installer_exit=1`, `done_claims=0`, P6 FAIL, and P9 FAIL. Comparator `rc=0` occurred 4/5 (19/19 checks; action-failure reason); comparator `rc=1` occurred 1/5 (18/19; dead hooks active count `2`). The rate is the finding; no comparator verdict is claimed.
- Timings/load: runs 1–2 NOT MEASURED; run 3 rc1 elapsed 912s, load 7.79/7.51/8.93 -> 12.28/14.82/11.79; run 4 rc0 elapsed 938s, load 12.28/14.82/11.79 -> 9.84/15.18/13.83; run 5 rc0 elapsed 954s, load 9.84/15.18/13.83 -> 3.94/4.76/8.18. Load does not explain this sample monotonically.
- The `P6=FAIL` row remains untouched; P6 failed 5/5 while its reason signal varied. No comparator widening was performed. Checkout-source control independently exhibited the rc1/dead-hooks outcome, but its reproducibility was not separately measured.
- #869 out-of-scope finding: current `defaultSupervisorProbe` checks bundled supervisor artifact presence and a resolvable socket path, not socket existence. The 2000ms capability-probe timeout is a code-read hypothesis for variance, NOT MEASURED as causal.
- Final-tree R7 deleted the three local-source binding exports temporarily. The realised source reverted to `4df478cd…` / `3e6d831…`, SOURCE-CONTROL failed against `ff3f0d29…` / `944c6db…`, and comparator `rc=1` with 8/19 mismatches. The subject file SHA-256 was `a93113565aa69f2c6f3d792b78251021bb3bbe3f7813d5fed547ab0099fa3b98` before mutation and after restoration.
- Trust boundary: the exact-commit URL trusts the configured repository provider's authenticated commit-to-archive mapping. The computed digest pins transfer/consumption but does not authenticate against repository/TLS compromise; signed provenance remains the canonical PRD v2 §3 deferral. Initial Codex security review retained this as HIGH/CWE-494; no stronger claim or out-of-scope signing change was made.
- Final baselines: Bash syntax, ShellCheck, `pnpm test:installer`, `pnpm typecheck` (45/45), `pnpm lint` (25/25), `pnpm format:check`, and `git diff --check` pass. Codex code review APPROVE confidence 0.92 with zero findings; after explicit trust-boundary documentation, security re-review risk NONE confidence 0.96 with zero findings. The initial HIGH trust-root finding remains recorded as the signed-provenance deferral.

-
-## Round 4 — pipeline case-coverage denominator
-
- Pipeline 2242 at `0e2eef1c` superseded the lane lead's earlier pipeline-2229 ruling: requirements 1–3 were already satisfied. The temporary local P6-consumer edit started while that ruling was in flight was restored; `tools/e2e-install-test.sh`, the expected-RED manifest, the per-case verifier, and #869 remain unchanged in the final tree.
- Requirement 5 adds a pipeline-level instrument above the three per-case invocations. Expected names are derived from the manifest, markers are scoped by pipeline+workflow run, and each marker is written only after that exact per-case verifier succeeds. Every producer depends on initialization; the final step depends on the complete case/contract matrix, runs after success or failure, and requires exact expected/actual set equality rather than count equality.
- Measured firing controls: skipped arm `3/2` rc1; count inflation `3/3` rc1 with one missing and one unexpected name; stale re-initialized run `3/0` rc1; exact set `3/3` rc0; future manifest case `4/3` rc1. Codex review found and blocked two independent defects: first the missing `depends_on` graph, then comment lines being parsed as case names. Both were accepted; dependency edges are regression-asserted, blank/comments are excluded, and the focused test now consumes the production manifest directly. Final Codex code re-review APPROVE confidence 0.94 and security re-review risk NONE confidence 0.96, both with zero findings. Woodpecker strict lint, Bash syntax, ShellCheck, focused/full installer tests, typecheck, lint, Prettier, and diff check pass.
- Full evidence: `docs/reports/verification/1050-c1-fix-round/10-round4-case-coverage.txt`.
-
-## Round 5 — arm coverage and checkout purity
-
- Reviews 110/111 identified two blockers at `f33bd0da`: the three-case set could not represent the fourth `greenfield-remote-installer-contract` arm, and the root `.greenfield-case-state` directory was included in checkout fixture archives. The expected-RED manifest, per-case verifier, detector, and #869 remain fenced.
- RED controls: with all three cases complete and no remote-arm identity, the old gate returned rc0 at `cases_defined=3 cases_executed=3`; the exact fixture tar selector archived `.greenfield-case-state/remote-arm.ran` once.
- The checker is generalized across exact `cases` and `arms` dimensions. A new explicit four-arm declaration includes the remote contract; all four arms mark only after successful per-case verification. With the remote omitted, cases remain 3/3 rc0 while arms report 4/3 rc1 and name `greenfield-remote-installer-contract` as missing.
- State moved beneath `.mosaic-test-work/greenfield-execution-coverage`, which the existing checkout selector excludes. The regression control proves a non-excluded root marker is archived while no `.mosaic-test-work` path is archived.
- Final review: Codex code APPROVE confidence 0.93 and security risk NONE confidence 0.96, both with zero findings. Full installer tests, typecheck 45/45, lint 25/25, format, Bash syntax, ShellCheck, Woodpecker strict lint, and diff check pass with 11G free before/after.
- Full evidence: `docs/reports/verification/1050-c1-fix-round/11-round5-arm-coverage-and-purity.txt`.
-
-## Round 6 — executable aggregation and production archive binding
-
- Reviews 114/115 independently reproduced the same caller-level mutant at `df705828`: ignoring `arms_status` in the workflow still left the helper-bounded focused suite green. The production OR was correct and was not rewritten; its aggregation moved byte-for-byte into `verify-greenfield-execution-coverage-gate.sh`, which the workflow invokes directly.
- The focused suite now exercises that exact helper across the complete truth table: cases PASS/arms FAIL RED; cases FAIL/arms PASS RED; both FAIL emits both outputs and is RED; both PASS GREEN. Local ignore-arms, ignore-cases, and always-RED mutants each make the suite RED.
- Review `rev-974` separately proved that deleting only the production `e2e-install-test.sh` `.mosaic-test-work` tar exclusion left the copied-selector control green. The control now structurally binds its semantic archive test to the production checkout-archive command; the delete-production-binding mutant is RED. The fenced production installer remains byte-unchanged.
- Final review: Codex code APPROVE confidence 0.94 and security risk NONE confidence 0.97, both with zero findings. Full installer tests, typecheck 45/45, lint 25/25, format, Bash syntax, ShellCheck, Woodpecker strict lint, focused truth-table and four mutant controls, and diff check pass with 11G free before validation.
- Full evidence: `docs/reports/verification/1050-c1-fix-round/12-round6-caller-coupling-and-archive-binding.txt`.
-
-## Round 7 — canonical Alpine/BusyBox portability
-
- Review 119 found the exact-head focused suite RED in the canonical Alpine `ci-base`: GNU `find -printf` is unsupported by BusyBox 1.37. The same script remained green in the Debian greenfield workflow, so greenfield success alone did not prove canonical runtime compatibility.
- Local canonical-image RED was reproduced at rc1 before remediation. Marker inventory now uses Bash nullglob/dotglob and parameter expansion, checks state-directory readability, preserves the prior regular-file/non-symlink boundary, and retains sorted exact-set comparison without GNU-only flags.
- The focused suite is green both locally and inside `git.mosaicstack.dev/mosaicstack/stack/ci-base:latest`. Canonical pipeline evidence remains pending the replacement frozen-head push; no stale pipeline is inherited.
- Final review: Codex code APPROVE confidence 0.96 and security risk NONE confidence 0.97, both with zero findings. Full installer tests, typecheck 45/45, lint 25/25, format, Bash syntax, ShellCheck, Woodpecker strict lint, dual-runtime focused tests, retained Round-6 mutants, and diff check pass with 11G free.
- Full evidence: `docs/reports/verification/1050-c1-fix-round/13-round7-busybox-portability.txt`.
-
-## Round 8 — pipefail-safe expected-set membership
-
- Review 122 found `expected_names | grep -Fxq` could falsely reject a valid early-sorted marker: `grep -q` closes after its match, the upstream sorter can exit 141, and `pipefail` selects that producer failure. Independent canonical-Alpine stress measured failures at the live four-arm manifest size, so no safe small-set threshold is claimed.
- A deterministic 20,001-entry real-script mark control makes the unfixed canonical-Alpine path RED with `case is not in the expected set: a-target`. The mark path now materializes and validates the complete expected-name snapshot before applying `grep -q` via a here-string, eliminating the producer/consumer pipe while retaining fail-closed producer errors.
- The focused suite is green locally and in canonical Alpine after remediation. A separate 1,000-mark canonical-Alpine stress against the live four-arm production manifest recorded zero false failures.
- Final review: Codex code APPROVE confidence 0.96 and security risk NONE confidence 0.98, both with zero findings. Full installer tests, typecheck 45/45, lint 25/25, format, Bash syntax, ShellCheck, Woodpecker strict lint, canonical deterministic/stress controls, retained Round-6 mutants, and diff check pass with 11G free.
- Full evidence: `docs/reports/verification/1050-c1-fix-round/14-round8-pipefail-membership.txt`.

+# 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 fixture itself is intentionally RED until the C2-C5 phase owners repair
-# their postconditions. C1's CI gate executes it and validates that the RED is
-# attributable (including the discriminating P3 PASS); it does not turn the
-# failed install into a false green.
+# Runs a clean-container install test to verify the full first-run flow:
+#   tools/install.sh  ->  mosaic wizard (non-interactive)
+#                     ->  mosaic gateway install
+#                     ->  mosaic gateway verify
+#
+# Usage:
+#   bash tools/e2e-install-test.sh
+#
+# Requirements:
+#   - Docker (skips gracefully if not available)
+#   - Run from the repository root
+#
+# How it works:
+#   1. Mounts the repository into a node:22-alpine container.
+#   2. Installs prerequisites (bash, curl, jq, git) inside the container.
+#   3. Runs `bash tools/install.sh --yes --no-auto-launch` to install the
+#      framework and CLI from the Gitea registry.
+#   4. Runs `mosaic wizard --non-interactive` to set up SOUL/USER.
+#   5. Runs `mosaic gateway install` with piped defaults (non-interactive).
+#   6. Runs `mosaic gateway verify` and checks its exit code.
+#      NOTE: `mosaic gateway verify` is a new command added in the
+#      feat/mosaic-first-run-ux branch. If the installed CLI version
+#      pre-dates this branch (does not have `gateway verify`), the test
+#      marks this step as EXPECTED-SKIP and reports the installed version.
+#   7. Reports PASS or FAIL with a summary.
+#
+# To run manually:
+#   cd /path/to/mosaic-stack
+#   bash tools/e2e-install-test.sh
+#
