+  "2026-10-12T13:25:56.037Z",codex-sol,"Plan: use individual REST issue endpoints for explicit selection, validate all numbers before tracker mutation, preserve the shared comment/dependency/atomic/gate pipeline and provenance idempotency. List limits request newest-updated order and stop after one extra eligible issue establishes truncation. Add recorded public fleet REST fixtures and real scratch-tracker regressions. Keep PR #115 blocker code outside this diff."
+  "2026-10-12T13:34:57.011Z",codex-sol,"Implemented selection prefetch and missing-number/PR refusal before writes, conflict validation, and bounded newest-updated list fetches with limit/truncated receipts. Recorded public REST fixtures cover pm-web #189/#96/PR #175 and pm-slack-standup #113. Initial focused run passed 23/26; fixture assertions needed existing body trimming and native-comment reads, and CLI acceptance now installs a packed archive because directory installs hit the SDK source-scan ceiling. Type checking, documentation, lint, zero-duplication and privacy gates pass."
+  "2026-10-12T13:37:55.946Z",codex-sol,"Live manual acceptance passed using the packed candidate in a scratch pm project: pm github import unbraind/pm-web --issue 189 --dry-run --json reported wouldImport=1, wouldUpdate=0, wouldSkip=0 and left tracker count=0. pm github import unbraind/pm-web --issue 189 --json reported imported=1, updated=0, skipped=0; the tracker contained exactly one item with gh:unbraind/pm-web#189. Both used the real public GitHub endpoint. Corrected focused acceptance passed 3/3, including comments and packed CLI dispatch."
+  "2026-10-12T13:43:05.407Z",codex-sol,"Behavioral revert proof passed in disposable copies of the candidate with unchanged regression tests and fixtures: restoring only runImport from the base revision made the one-recorded-issue regression fail 0/1 with AssertionError (2 imports instead of 1). Restoring only buildIssuesUrl and fetchAllIssues made the bounded-probe regression fail 0/1 with AssertionError (3 retained issues instead of 2). Candidate source bytes stayed unchanged. These tests import TypeScript source, so no dist rebuild was needed for the revert experiments."
+  "2026-10-12T13:47:07.209Z",codex-sol,"Isolated-Git-identity npm run release:check passed: 546/546 tests, zero failures/cancellations/skips/todo; 12 authored modules with exact 100/100/100/100 coverage (8597/8597 lines and statements, 211/211 functions, 2315/2315 branches). Type checks, build, docstrings, lint, zero duplication, privacy, production audit (0 vulnerabilities), pack dry-run, changelog and publish-attestation checks all passed. The Bun release chain is running. PM-linked execution reached 25 passing cases before its default 120-second timeout during the final acceptance; rerunning with --timeout 300. Tracker test-result persistence is disabled by existing project policy, so comments retain receipts."
+  "2026-10-12T13:49:47.304Z",codex-sol,"PM-linked acceptance passed with pm test pm-github-6srd --run --progress --timeout 300: 1/1 linked commands and 26/26 regression cases, zero failures/cancellations/skips/todo, elapsed 188 seconds. Increased the linked command budget to 300 seconds for repeatability on the shared runner. The earlier default-budget timeout is retained as a timeout receipt, not a passing result."
+  "2026-10-12T13:57:04.892Z",codex-sol,"Final isolated-Git-identity bun run release:check passed: 546/546 tests, zero failures/cancellations/skips/todo; 12 authored modules with exact 100/100/100/100 coverage (8597/8597 lines and statements, 211/211 functions, 2315/2315 branches), unchanged thresholds and inventories. All release-chain checks passed, including zero production vulnerabilities, packing, changelog and publish attestation. Bun orchestrates the release chain; its coverage runner invokes Node. Implementation, docs, tests and fixture hashes match the source validated by the npm gate. Manual public selection, both assertion-based revert proofs, and PM-linked 26/26 acceptance are complete. No blocker code changed. Claims will be released; the item remains in progress for PR review."
