+# Phase 1 Experimental 0.4.3 prepublication checks
+
+Assessment date: 2026-09-07 UTC.
+
+This record covers checks performed before publishing the 0.4.3 candidate.
+It does not establish public availability, independent external verification,
+P1 Validated status, or Stable-promotion approval.
+
+## Candidate identity
+
+- Version: `0.4.3` across all five packages.
+- Candidate manifest: `release/p1-release-candidate.json`.
+- Assessed correction commit: `08907b8c21d0f21a5f022b4740271dd153943583`.
+- Dev integration commit: `4f5b5a033899e3ee9323e1c087df08e8d31955d6`.
+- Correction: refresh the supply-chain assessment from August 23 to September 7.
+- The correction changes no candidate package digest.
+- Release channel: `experimental`; preserved Stable channel: `latest` at `0.3.2`.
+
+The final release tag must identify the approved main promotion commit.
+Neither commit above is a substitute for that final main identity.
+
+## npm identity and publisher controls
+
+Authenticated package-access checks confirmed write access to every package.
+All five `npm trust list` checks returned the following exact configuration:
+
+| Package | Provider | Repository | Workflow | Environment |
+| --- | --- | --- | --- | --- |
+| `@launchrally/contracts` | GitHub | `codeacme17/launchrally` | `release.yml` | `npm` |
+| `@launchrally/core` | GitHub | `codeacme17/launchrally` | `release.yml` | `npm` |
+| `@launchrally/cli` | GitHub | `codeacme17/launchrally` | `release.yml` | `npm` |
+| `@launchrally/codex-plugin` | GitHub | `codeacme17/launchrally` | `release.yml` | `npm` |
+| `@launchrally/claude-plugin` | GitHub | `codeacme17/launchrally` | `release.yml` | `npm` |
+
+Each publisher allows `publish` and `stage publish`. The release workflow uses
+the approved direct publication path; no publisher configuration was changed.
+The GitHub `npm` environment requires deployment review and permits `v*.*.*`
+tags. An active tag ruleset protects `refs/tags/v*.*.*`.
+
+At assessment time all five public `experimental` tags resolved to `0.4.2`,
+and all five `latest` tags resolved to `0.3.2`.
+
+## Verification results
+
+| Check | Result |
+| --- | --- |
+| Locked dependency installation with scripts disabled | Passed |
+| Build and generated Skill synchronization | Passed; no generated diff |
+| Supply-chain test suite | 68 passed, 0 failed |
+| Full test suite after the assessment correction | 849 passed, 0 failed, 3 existing TODOs |
+| Exact packed-artifact journeys within the full suite | Passed |
+| Acceptance traceability | 25 P0 requirements, 39 P1 requirements, 17 release gates validated |
+| P0 governance | Passed |
+| P1 publication readiness | 39 requirements and 5 mandatory gates validated |
+| Tagged release validation for `v0.4.3` | Passed on the assessment date |
+| Candidate digest verification | All five npm pack digests match the committed manifest |
+| Independent standards and specification review of the correction | No findings on either axis |
+| Correction PR CI | All nine executed jobs passed; branch-policy job skipped |
+
+The separate optional preflight fan-out was declined by the maintainer.
+Same-day tagged-release validation must be repeated if publication moves to
+another UTC date; this record does not extend the assessment's validity.

+## Public references and remaining gates

+- [Assessment correction PR #213](https://github.com/codeacme17/launchrally/pull/213).
+- [Correction CI](https://github.com/codeacme17/launchrally/actions/runs/34081920547).
+- [Main promotion PR #212](https://github.com/codeacme17/launchrally/pull/212).
+- [Release tracker #210](https://github.com/codeacme17/launchrally/issues/210).
+
+Main promotion, protected annotated-tag publication, public digest/provenance
+smoke, and the published-artifact Human Mode checks required by #187 remain
+separate gates. Independent CLI, Codex, and Claude external verification must
+be recorded through the existing signed-result procedure after publication.
+No public-release or external-verification gate is marked complete here.
