docs(devlog): close out the bug-labelled drawdown campaign - #3311
Conversation
Records the sixteen merges with their ancestor-proved shas, the three issues that ended NEEDS_HUMAN and why a diff would have been a guess, and the four things the process caught that a green build would not: a plan audit that failed four times over two factual errors in my own writeup, an allowlist that passed every test and rejected a real config in the browser, CI catching two contract breaks in my own change plus a subagent relaxing an existing security assertion to fit its implementation, and a contribution that silently reverted an earlier fix. Also lists the three macOS timing flakies that recurred across this campaign, so the next person does not re-investigate them.

This file declares the campaign DONE with every tracked item in a terminal state, but it leaves the entire unit under devlog/_plan, so tooling or maintainers enumerating that directory will incorrectly treat the campaign as open. Move devlog/_plan/260903_bug_drawdown_bcda to the corresponding path under devlog/_fin as part of this closeout.

Qualify the #3245 test evidence.
The phase record in devlog/_plan/260903_bug_drawdown_bcda/090_phase9.md, Lines 8-20, states that tests/server-auth.test.ts:1384-1422 predates v2.39.0. State that this is a historical control test. Do not present it as current-version regression coverage.
Proposed wording
- The control test `tests/server-auth.test.ts:1384-1422` passes.
+ The historical control test `tests/server-auth.test.ts:1384-1422` passes; it predates v2.39.0 and does not replace a 0.152.1+ reproduction.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Keep the #3279 conclusion within the available evidence.
The phase record in devlog/_plan/260903_bug_drawdown_bcda/060_phase6.md, Lines 5-35, says that no intermittent invalidation mechanism could be established. It does not prove that no such mechanism exists. Use “could be established” or “was not identified” because the issue remains NEEDS_HUMAN.

Complete the flaky-test references.
The PR objective says the report records the three recurring macOS timing flakes with their files and constants. Only shutdown-launcher has both. Response spill shutdown fallback budget exhausted has no file, and CL-07 task effectiveness producer > inactivity timeout is bounded has neither a file nor a constant. minimax-clients also lacks both and is not clearly classified. Add the exact references, or mark unavailable values explicitly.

Summary
Closeout record for the 2026-09-03 bug-labelled drawdown. Documentation only — no runtime code is touched, and nothing in the build, typecheck, or test path reads from
devlog/.It records the sixteen merges with their ancestor-proved shas, the three issues that ended NEEDS_HUMAN and why writing a diff for them would have been a guess, and four things the process caught that a green build would not:
note.safeConfigDTOsecurity assertion to fit its implementation. The test was restored verbatim instead.It also lists the three recurring macOS timing flakies with their file and constant, so the next person does not re-investigate them.
