  FNXC:CliTests 2026-06-14-01:36:
  The full @runfusion/fusion package lane timed out or leaked mock state across 24 CLI integration-heavy files under changed-test load, while the same files passed in smaller direct runs.
  They were quarantined per the flaky-test deletion ratchet instead of raising the 5s test timeout or relaxing assertions.

  FNXC:CliTests 2026-06-14-05:50:
  FN-6427 triaged all 24 quarantined CLI files and kept them in-window: 0 rescued, 0 deleted, 24 kept until the 2026-06-27 and 2026-06-28 deletion deadlines.
  Fresh direct runs passed, and the shared package-load signature needed a broader fixture/concurrency rescue before these high-value suites could safely rejoin the default lane.

  FNXC:CliTests 2026-06-14-01:42:
  FN-6430 rescued all 24 CLI quarantine entries after fixing shared test-isolation cleanup, rejecting inherited HOME roots from other invocations, removing pre-existing file-wide timeout bumps, and narrowing the mission real-store seam.
  Keep this array as an explicit empty rescue ledger so future CLI quarantines add entries in lockstep with scripts/lib/test-quarantine.json instead of resurrecting stale excludes.

  FNXC:CliTests 2026-06-15-04:07:
  FN-6483 observed extension-task-tools timing out only under the full @runfusion/fusion package lane while passing standalone immediately afterward.
  Quarantine the suite for the 14-day deletion ratchet instead of appeasing the load-sensitive timeout with wider test timeouts, retries, or worker changes.

  FNXC:CliTests 2026-06-15-07:46:
  FN-6486 rescued extension-task-tools by closing real TaskStore fixtures and replacing hoisted mock cleanup, then removed the quarantine in lockstep with scripts/lib/test-quarantine.json. Keep this array empty unless a future observed CLI flake is mirrored in the ledger in the same commit.

  FNXC:CliTests 2026-06-19-11:43:
  FN-6705 verification observed five CLI extension-tool files fail under the broad changed-package lane with test timeouts, ENOTEMPTY cleanup, or cross-test state drift; all except extension-task-tools passed in the direct failure-batch rerun, and extension-task-tools remained timeout-sensitive. Quarantine these existing integration-heavy files under the deletion ratchet instead of widening testTimeout, adding retries, or weakening assertions.

  FNXC:CliTests 2026-06-20-09:48:
  FN-6795 reloaded the five remaining 2026-06-19 CLI extension/research quarantines under the full @runfusion/fusion package lane after the FN-6734 close-before-remove seam and found no timeout, ENOTEMPTY, or cross-test state drift. Keep this exclude list empty in lockstep with scripts/lib/test-quarantine.json; future CLI load flakes must prove a new cleanup invariant before quarantine.

  FNXC:CliTests 2026-06-20-10:04:
  FN-6795 final loaded verification re-exposed extension-task-tools, extension.test's built-dist-barrel case, and bin's no-args dashboard launch as package-lane-only timeouts while targeted reruns passed. Retain/quarantine these files in lockstep with the ledger rather than widening 5s/15s timeouts, adding retries, or changing worker budgets; the 2026-06-19 entries still delete on 2026-07-03 unless a real fixture-load invariant is found.

  FNXC:CliTests 2026-06-21-09:58:
  FN-6839 rescues the retained bin, extension-task-tools, and extension suites by awaiting async TaskStore/cache shutdown before temp-root cleanup and proving the grouped/package lanes can run unexcluded. Keep the exclude list empty in lockstep with scripts/lib/test-quarantine.json; do not re-quarantine this loaded-lane signature without a new root-cause invariant.

  FNXC:CliTests 2026-06-26-09:30:
  extension.test.ts failed in CI full-suite shard 3/4 with 'Target cannot be null or undefined' in the fn_delegate_task test and was quarantined under the deletion ratchet.

  FNXC:CliTests 2026-06-27-10:05:
  FN-7119 re-ran extension.test.ts twice with the exclude removed and the fn_delegate_task null-target symptom no longer reproduces at HEAD. Keep this list empty so delegate-task validation coverage stays active in the package lane.

  FNXC:CliTests 2026-07-04-10:40:
  FN-7447 re-quarantines extension.test.ts after its built-dist-barrel fn_task_list test (line ~3084) timed out at 5000ms in full-suite shard 4/4 (run 28697507894) while passing locally at ~1.2s and in 3 of the 4 surrounding CI runs. The root-cause invariant is the loaded-lane signature: in-test dist-barrel recompilation (vi.resetModules + vi.importActual of the full @fusion/core dist barrel + a fresh dynamic import of extension.js) inside the default 5s timeout is CPU-bound and degrades non-linearly under 4-shard CI contention. This is the same signature rescued in FN-6483/FN-6705/FN-6795/FN-6839; widening the timeout is forbidden by the flaky-test rule and removing the recompilation removes the test's only purpose, so the file is excluded per the deletion ratchet rather than re-attempting a fifth fixture rescue. Mirrors scripts/lib/test-quarantine.json; collateral is the ~68 otherwise-stable tests in this file, recoverable via rescue before the 2026-07-18 deletion deadline.

  FNXC:CliTests 2026-07-04-13:50:
  FN-7530 resolved the FN-7447 entry: RESCUE-by-split, not delete. The single dist-barrel recompilation test (unchanged assertions) moved to packages/cli/src/__tests__/extension-dist-barrel.test.ts; extension.test.ts is back in the default lane and its ~68 stable tests run again. The isolated file still stays quarantined here under its OWN fresh entry, because the root cause is loaded-lane CPU contention during vi.resetModules()/vi.importActual(dist barrel)/dynamic import() -- a property of that operation under 4-shard CI, not of file layout -- so splitting the file does not by itself make it safe to re-admit, and with only one test in the file there is no second call site to amortize a module-top-level rescue against. No testTimeout widening, retries, or worker/concurrency changes were made. Mirrors scripts/lib/test-quarantine.json; this isolated file's own 14-day deletion clock is due 2026-07-18.
