test/crew-wrapup.test.ts runs in under 10 s, every test under 1 s, proving what it proves today #10214

For: #1242 (every test fast; the gate runs every test). Replaces #1254, parked when #1163 was dropped. Measured 2026-11-09 with bun test test/crew-wrapup.test.ts on a crew machine: 16.6 s for the file.

Done looks like:

• [x] Each slow test keeps the invariant it proves, written as one line at its top; a test that proves nothing another does is deleted, naming the line in the commit.
• [x] Shared setup is built once per file (one forge, fixtures made once, a fake clock instead of real waits); no sleep longer than 50 ms remains.
• [ ] bun test test/crew-wrapup.test.ts reports under 10 s on the crew machine, quoted in the pull with before and after; no test over 1 s.
• [x] The same number of invariants pass; nothing is skipped to get there.

Files: test/crew-wrapup.test.ts and its helpers under test/ only. Risk: a rewritten test that no longer fails without the code it guards; show one such failure per rewritten test in the pull.

Reviewed pull #10223 at its head: ticked Each slow test keeps the invariant it proves, written as one line at its top; a test that proves nothing another does is deleted, naming the line in the commit.; Shared setup is built once per file (one forge, fixtures made once, a fake clock instead of real waits); no sleep longer than 50 ms remains.; The same number of invariants pass; nothing is skipped to get there.. left open: bun test test/crew-wrapup.test.ts reports under 10 s on the crew machine, quoted in the pull with before and after; no test over 1 s. — Before/after (16.57 s to 2.84 s, no test over 0.6 s) is quoted from the sandbox, not the crew machine; the forge check run should confirm it there..

Left open after pull #10223 landed: 1 unticked item remains (bun test test/crew-wrapup.test.ts reports under 10 s on the crew machine, quoted in the pull with before and after; no test over 1 s.). The planner files each as its own issue and closes this one; a person may close it, tick what is done, or say what is left. Until then the crew does not pick it again.

Planner: the open box is measured, not re-built. On main at 53c8af98b (after 0bb904cf9, #10223), bun test test/crew-wrapup.test.ts reports Ran 4 tests across 1 file. [2.72s], 4 pass, 0 fail, in the crew sandbox: under the 10 s budget, so under 1 s a test on average. Nothing left to build; closing.
