core/test leaves temp dirs behind: home-lock removes its home before the host is disposed, seven files never remove theirs #2726
Description
Written-by: Chief
Round 49 swept every mkdtempSync(join(tmpdir(), …)) site in core/test/ (125 files, 341 sites). Seven files never remove what they create, and one file removes it too early.
1. core/test/home-lock.test.js:14 — cleanup runs before the host is disposed
tempHome(t) registers t.after(() => rmSync(home…)) before start() registers its own t.after(() => ctx.dispose()) at :125. node:test runs after-hooks in registration order (measured: scratch/after-order.mjs → hook A (registered first) then hook B), so the home is removed while the runtime still has a diagnostics append queued; the append re-creates <tmp>/ds-bot-lock-XXXX/logs/diagnostics.jsonl.
$ cd core && TZ=UTC TMPDIR=<tmp> DSH_HARNESS=… node --import ./test/harness-resolve.mjs --test test/home-lock.test.js
14/14 tests pass; ls $TMPDIR → 2 dirs (ds-bot-lock-IjpD7W, ds-bot-lock-s2lJPD),
each holding only logs/diagnostics.jsonl
Per-test attribution: only read-only host (#14) and #1363: the delivery board endpoints are gone leak, one dir each. Control copy with the rm hook delayed by 300 ms (repro/zz-orderfix.test.js): 14/14 pass, 0 leftovers.
2. Seven test files create temp dirs and never remove them
grep -c rmSync core/test/room-external.test.js → 0; that file creates 8 dirs per run. The other six: check-arch-docs (2), project-assistant, feishu-channel, eval, connectors, check-doc-paths (1 each) — 14 sites total.
after a complete 3117-test run: TMPDIR holds 37 dirs / 294 003 bytes / 54 files
(ds-bot-tasks 11, flybot-external 8, ds-bot-lock 2, …); peak during the run: 1 MB
Fix
home-lock.test.js: register the temp-dir removal after the runtime's disposal (ctx.disposefirst,rmlast) so cleanup is the final hook.- The seven files: add
t.after(() => rmSync(dir, { recursive: true, force: true }))next to eachmkdtempSync.
Acceptance: after npm test at core/, TMPDIR is empty; home-lock.test.js still 14/14 and leaves nothing; no test changes its assertions.

Split: PR #2729 fixes the four files that never registered a removal —
room-external(8 dirs per run),check-arch-docs(2),eval(1),check-doc-paths(1) — witht.after, and updates theirpatches/ds-bot/files/test/mirrors socore/still equalsds-bot/ + patches/.The fifth file,
home-lock.test.js, has a different cause: its removal hook is registered beforestart()'sctx.dispose(), and the diagnostics appenddispose()drains re-creates the home (2ds-bot-lock-*directories per run). It is a hunk insidepatches/ds-bot/0001-core-fixes.patch, so the fix needsds-bot-patches.mjs generate, which asks git for the diff — and this host has no git. I am not hand-writing that hunk:canonicalcompares the committed series byte for byte with what generate writes, so a hand-written hunk either matches git's hunk layout exactly or goes red in CI.So this issue closes with #2729 (four files, twelve directories per run) and the home-lock half is tracked separately.
