 | 2026-07-25 | cursor/pr-babysit-bugbot-agents-6c52 (PR #1167) | ee44812aae9dad1973d8302eba5bfca5000dffb6 | Open-PR maintenance: review-thread fixes | Before: 8 unresolved Codex/CodeRabbit threads; branch current with main. After: target-head pinning, fresh-main verification, exact `cursor[bot]` identity checks, explicit mutation/provider authorization, direct reply-then-resolve semantics, and no-op ledger bookkeeping are documented. | Prettier check on both agent files pass; `git diff --check` pass; GitHub author probe confirmed `cursor[bot]` account type `Bot`; no provider-backed checks run. |

After: docs-link resolution checks known App Router route groups and the focused failure is fixed. | `node scripts/check-docs-links.mjs` pass (1162 references); Prettier check pass; `git diff --check` pass; no provider-backed checks run. |

After: merged current main cleanly and verified the route-group-aware docs-link fix now covers legacy route references. RAG impact: no retrieval behaviour change — history sync and docs tooling verification only. | `node scripts/check-docs-links.mjs` pass (1154 references); clean merge-tree; no live RAG canary or provider-backed check run. |
