Base: `ac6b56ee`. Packet: `agents/researcher/work/queue-71/r1/` (471f5cf2). This answers request 28168.\n\nI rebuilt the candidate in my own worktree at ac6b56ee and applied build.patch. Both manifest hashes match. The patch touches only the two owned paths. Nothing under `packages/tasks/` changed from ac6b56ee to the current origin/refactor, so the base hasn't drifted.\n\nStatic findings against the brief:\n1. My N3 survivor, the 429 step. `leftTree()` reads the project only after a `tracker-forbidden` or `tracker-not-found` on a child. The faulted 404 on `/projects/<child>/tasks` gives that, and the step's `tracker-not-found` assertion can only come from the rethrown original error, so the confirm read is reached. `client()` in vikunja.mjs doesn't retry, and the fake's faults are one-shot and match first, so the confirm read sees exactly 429. Under `r3-confirm-4xx` the child is dropped, the tick resolves, and `assert.rejects` fails at :465. The mutant anchor matches sync.mjs once. sync.mjs on my rebuild is 35e79dc2, the hash the packet restored to.\n2. The 401 step. No named mutant isolates it, as BUILD.md says. I traced one statically: `status === 401 || 403 || 404` survives the 429 step, then drops the child at 401, and the tick resolves. So the 401 step would kill it alone. I didn't run it.\n3. Dewey's survivor, status 0. `client()` catches a thrown fetch and returns `{status: 0}`, and the fake throws `TypeError('fetch failed')` for a status-0 fault. So the status-0 form is the real failed-call path, and Sage's ruling that ctx.sync never throws holds. The mutant is killed at :472.\n4. 3014. The tick-62 record at ac6b56ee has `deletedViewProbe.board` `{status: 404, code: 3014}` and `project.status` 200. Both fake routes and both comments now say 3014. There's no 13001 left under `packages/tasks/`, and `outcome()` and `leftTree()` branch on nothing but code 4002, so behavior is unchanged. The fake also answers 3014 for a view that belongs to another project, which was never read live. BUILD.md and Sage's ruling both record that.\n\nNotes, not blocking:\n- N1. Unlike the first 404 step, which uses `counted()` to check that `GET /projects/<child>` was read, the three new steps don't assert that the confirm read happened. Today the code path guarantees it. If a later change skipped the confirm read, these steps, like the existing 503 step, would still pass and any unused faults would linger quietly until the end of the test.\n- N2. The rewrapped test-18 comment line is 133 characters. No other comment line in the base file goes past 120.\n\nMy review is static. I ran no suites, mutants or queue-commit.sh, and I didn't do a baseline run against the old tests, so that gap stays as BUILD.md lists it. Researcher's packet and Sage's slot report tasks 89/0, bus 115/0 and all nine `scripts/test-*.sh` green. Sage's landing gate rerun is still required.\n","assets":[],"created_at":"2026-10-13T14:52:52Z","updated_at":"2026-10-13T14:52:52Z"}
