🤖 ## Summary This PR removes two CI flakes that failed relay-stack runs on 2026-10-13. Both passed when rerun. - **Detect Changed Paths timeout.** This first CI job had a 2-minute limit. Its steps take about 75 seconds, but GitHub sometimes finishes the job minutes after the last step. In three runs, every step had finished, but GitHub still cancelled the job at the limit, and all later jobs failed. The limit is now 10 minutes. - **PostgreSQL deletion test.** `approval_boundary_blocks_claim_until_exact_inventory_is_approved` sometimes could not claim an approved deletion request. This was a race in the test, not a product bug. How the test race happens: - The test sends an UPDATE that the database must reject. Then it claims the same row. PostgreSQL sends the error to the client before it rolls back the statement and releases its row lock. sqlx returns as soon as it gets the error. - The claim runs on another pooled connection with `FOR UPDATE ... SKIP LOCKED`. It can skip the row while the lock is still held, and return no claim. - The test now runs the rejected UPDATE on its own connection. Then it sends `SELECT 1` on that connection before it claims. That round trip completes only after PostgreSQL has finished the rollback. Production code does not change. A claim that skips a row locked by another transaction is correct behavior. I checked the other tests in this file. Only this test has a rejected write on the request row immediately before a `SKIP LOCKED` claim. In the other tests, a blocking `approve` call runs before the claim. ### Related issue N/A. No existing PR found. Failing runs: [timeout #8174](https://github.com/block/buzz/actions/runs/38468285648/job/115540525751), [timeout #8176](https://github.com/block/buzz/actions/runs/38468321774/job/115541550557), [timeout #8182](https://github.com/block/buzz/actions/runs/38468329504/job/115541197994), [deletion test #8182](https://github.com/block/buzz/actions/runs/38468329504/job/115550003726). ### Testing - I confirmed the order in the PostgreSQL 17 source: `EmitErrorReport()` (which flushes to the client) runs before `AbortCurrentTransaction()` in `tcop/postgres.c`. A BEFORE UPDATE trigger locks the row first (`GetTupleForTrigger` in `commands/trigger.c`). - I could not reproduce the failure locally: 0 failures in 410 runs, including runs on a CPU-limited PostgreSQL container. The fixed test passes against PostgreSQL 17.
