Fixes

• ci: skip credentialless non-strict scheduled Store status checks with a notice and fail strict dispatches (#144) (1507f53)

Documentation

• readiness: record the v0.5.0 release state and gate the recovery matrix (#144) (1507f53)

Maintenance

• ci: consume the Store status tool's service-account or OAuth credential contract (#144) (1507f53)
• store-assets: bind checked-in exports to their source SVG digests for verification (#144) (1507f53)

Pack Workflow Preflight

• Generated by Release Please. pnpm workflow:preflight runs in Review findings gate.

Privacy And Data-Flow Impact

• Release metadata only; no extension runtime, browser permission, host permission, network, credential, GST file, taxpayer-data, analytics, or telemetry behavior changes are introduced by this generated PR.

Sensitive Surface Review

• Release metadata only; no current-tab targeting, portal target binding, download completion, service-worker durability, local path, raw URL/referrer, or portal HTML behavior is changed by this generated PR.

Verification

• Pack CI and Review findings gate are required for the latest PR head.
• Release ZIP and provenance will be produced by the Pack Release workflow after the release PR merges.

PR Review Follow-Up

• Autogenerated review comments and inline review threads should be inspected before merging.
• Follow-up release hardening remains separate from this generated Release Please PR.
• Root cause: squash commit 1507f53 used a docs(readiness) title while also carrying CI and release-tool behavior, so Release Please classified the generated changelog entry as Documentation only. The existing logical-lane commit rule was not followed; this PR does not add a duplicate rule.
• Red-before-fix: pnpm exec vitest run tests/extension/version.test.ts exited 1 with both document claims at 0.5.0 while package.json was 0.5.1.
• Local verification at f3a0ec2: 104 Vitest files / 1680 tests passed; TypeScript, ESLint, Prettier, Actionlint, workflow preflight, git diff --check, WXT build, static package verification, ZIP build, and exact-ZIP verification passed.
• Privacy/public-claim review: no findings; historical Store evidence and all 54 recovery observations remain unchanged.

Thread	Disposition	Commit or evidence
Current-version documentation	fixed	e95ed4c, 765380d; release-please 0.5.2 simulation changed only README line 47 and readiness line 34
Executable changes missing from changelog	fixed	f3a0ec2; entries trace to 1507f53 workflow and asset-export diffs
