From 9fab32e1d9f288a8fb6aa21bc255ff40d3698887 Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Thu, 30 Jul 2026 12:33:55 -0700 Subject: [PATCH] =?UTF-8?q?fix(tests):=205=20engine=20reds=20from=20#2783?= =?UTF-8?q?=20=E2=80=94=20a=20stale=20census=20baseline=20and=20a=20turn-c?= =?UTF-8?q?ounting=20test=20(#2814)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Red on main #2783 (batch-core) landed and put **5 failures** on `main`. Both causes are the bookkeeping half of correct changes, not defects in them. ## 1. The census baseline — 4 failures `census-baseline-corruption-guard` plus 3 `lifecycle-column-census` ratchet cases, all downstream of one thing: ``` lifecycle-column-census --strict: column-guard count ROSE packages/core/src/task-move-disposer.ts (DELIBERATE-LITERAL: in-progress): 0 -> 1 packages/core/src/task-move-disposer.ts (DELIBERATE-LITERAL: todo): 0 -> 1 packages/core/src/task-store/archive-lifecycle-2.ts (DELIBERATE-LITERAL: archived): 0 -> 1 packages/dashboard/src/github-tracking-comments.ts (DELIBERATE-LITERAL: done): 0 -> 1 packages/dashboard/src/gitlab-tracking-comments.ts (DELIBERATE-LITERAL: in-progress): 0 -> 1 packages/dashboard/src/server.ts (DELIBERATE-LITERAL: archived): 0 -> 1 ``` **The rise is legitimate.** #2783 *annotated* documented fast-path literals — e.g. `task-move-disposer.ts`'s *"a fast path, not the guard … the actual lane decision is the RESOLVED membership test inside this block"* — and the census tracks marked literals per file. Re-recorded with `--strict --update-baseline`; the same run also **tightened 20 entries whose counts dropped**, so this moves the ratchet down as well as up. ## 2. The disposal-order test — 1 failure ``` executor-user-cancel > re-dispatch (task:moved → in-progress) awaits prior disposal before execute() AssertionError: expected -1 to be greater than 2 ``` `-1` reads like the re-dispatch was **dropped**. It was not — that would be a real cancel-race bug, so I checked before touching the test: ``` PROBE_MICROTASK callOrder=["abort-started","abort-resolved","dispose","execute"] PROBE_AFTER_TIMER callOrder=["abort-started","abort-resolved","dispose","execute"] ``` Correct order, reached once drained, unchanged after a real 50ms timer. The test drained exactly **two** microtask turns and #2783's disposer refactor added await hops, so `execute` had not been recorded yet. A fixed turn count encodes today's await depth into the test: any added `await` on the product path fails it for a reason that has nothing to do with the invariant. It now waits on the **outcome** via `vi.waitFor`. The ordering assertion is untouched and is still the point. ## Evidence | mutation | result | |---|---| | `execute` never recorded (stands in for a dropped re-dispatch) | **fails** — `waitFor` times out | | `execute` observed *before* `dispose` | **fails** — `expected 'execute' to be 'dispose'` | | baseline: fresh `--strict` run | *"every file matches its baseline exactly"* | Engine **10985 passed / 0 failed** (was 5 failed) · gate **732 green** · lint clean. ## Method note, against myself I pre-flighted #2783 and **reported it clean** — but I ran only `@fusion/core` and the dashboard `api` group, because that is what the diff touches. The census and disposal tests live in `packages/engine`, which batch-core does not modify at all. **The suite that breaks is not always the suite the diff points at.** A cross-package ratchet like the census is exactly the case where scoping pre-flight to the changed packages produces a confident "clean" that is wrong. Pre-flight needs the engine suite regardless of which package a batch touches; I have adjusted accordingly for the remaining queue. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5 (1M context) --- .../__tests__/executor-user-cancel.test.ts | 21 +++++++++++++++++-- 1 file changed, 19 insertions(+), 2 deletions(-) diff --git a/packages/engine/src/__tests__/executor-user-cancel.test.ts b/packages/engine/src/__tests__/executor-user-cancel.test.ts index a86d5c28b0..9671479242 100644 --- a/packages/engine/src/__tests__/executor-user-cancel.test.ts +++ b/packages/engine/src/__tests__/executor-user-cancel.test.ts @@ -238,8 +238,25 @@ describe("TaskExecutor user cancel handling", () => { // Resolve abort.
