AK resolver flake audit

One-line summary: fixed an existing stalled-stream test fixture so the timeout cleanup cannot later close an already-canceled controller during the expanded full suite.

Scope

Host: rdmsm4x
Project: amagansett-app
Mode: Prototype
Isolated worktree only: /Users/richh/dev/_handoff/codex-out/amagansett-ak-resolver-flake-20260825
Canonical checkout and active integration worktree were not edited.

Exact files touched

tests/unit/ak-resolver.test.ts — retain the delayed-close timer and clear it when the stream is canceled.
report.md — reproducibility and root-cause handoff.

Commands and verification

Investigated 95d724c: focused resolver runs passed, while full suite and resolver+Forst-manifest run reproduced Vitest's unhandled ERR_INVALID_STATE from the fixture timer.
After fix: 50/50 focused resolver runs passed; 30/30 full-suite runs passed (11 files, 69 tests per run, no unhandled errors).
npm run typecheck passed.

Commit and rollback

Commit: see git rev-parse HEAD in the isolated worktree (the branch is codex/amagansett-ak-resolver-flake-20260825).
Backup: original source remains recoverable at base commit 95d724cab0cfe6a802d6393e399729a502e749b6; no deployed state changed.
Undo: omit the isolated branch/worktree from integration, or revert the single test-file change after cherry-pick. Do not alter canonical checkout.

Outstanding owner action

Lead agent should review and cherry-pick the isolated test/report commit only after the active Forst/API writer worktrees are no longer being edited. No deployment is requested by this audit.
