test(http-readiness): widen the millisecond budgets Windows cannot hold, and record this session's findings - #2256
Conversation
"destroys stalled requests and resumes polling" fails on a Windows workstation in isolation, on an idle machine, running this file alone — not only under load: AssertionError: expected 4 to be 3 tests/http-readiness.test.ts:61:22 The server stalls its first two responses and ends the third. The client gave each attempt 40ms. The two stalls consume that budget by design, but so does a third response that merely arrives late, and then the loop polls a fourth time. 40ms is not a margin on Windows. Raised to 250ms, with the overall deadline lifted from 1s to 5s to leave room for two full stalls plus the real attempt. "honours the overall deadline when every response remains open" gets the same treatment from the other side. Every response stalls, so the deadline decides how many attempts fit: 180ms left room for four, and one late timer yields a single attempt and fails `toBeGreaterThan(1)`. That is the shape reported from the same workstation, and it recurred across many concurrent copies of this file. The deadline moves to 600ms, fitting roughly thirteen attempts, so the assertion needs the loop to poll rather than to win a race. No assertion changed. Both tests still demand exactly what they did before — three requests and a completed poll in the first, a rejected deadline and more than one attempt in the second — and the elapsed-time bound still holds. Proven both ways: five consecutive green runs, and breaking the stall-destroy path in http-readiness.mjs still fails both tests (they hang to the 30s limit), so the widened budgets have not made them unable to detect the regression they exist for.

… was wrong Four merge-safe inbox requests; none touches the canonical ledger. Corrects my own earlier record. The request filed in #2252 reasoned that failures 1 and 2 were deterministic state assertions and therefore real Windows-only defects rather than load noise. That was wrong for failure 1: the assertions are fixed, but the runtime is not, because the test spawns Git Bash twice. It is cancelled and replaced by one record carrying the resolved status of all five — two fixed (#2255, #2256), two unreproducible with a legibility fix (#2252), and hosted-migration-role-guard still genuinely unexplained, with the untracked-file hypothesis and the diagnostic to capture if it recurs. Updates #CCZ4HB with the second measurement of the review-bot budget: every PR opened this session was skipped, the countdown shrank across it, and the binding constraint has moved from the rate limit to the organisation spending cap — a billing decision no repo gate can substitute for. It also names the interaction worth writing down: the draft-by-default rule guarantees no bot review until someone undrafts, and undrafting mid-CI cancels the run and reds the required aggregate. Draft default, review budget and cancel-in-progress churn are one problem seen from three sides. Updates #6GW95D with a wider scope than it records. A stray `npx vitest` from the home directory enumerated 253 checkouts of this repository across six distinct roots — .codex, .gemini, .copilot, opencode, Documents/Codex, and a pnpm store with its own .worktrees. A sweep scoped to .claude/worktrees covers none of them. The #XCAX01 safety preconditions still apply before any pruning. Both updates restate the prior text verbatim rather than replacing it.

CodeRabbit flagged the new record's summary as not matching its detail. Checked: the summary was accurate as written — "2 of 5 fixed" is true of the five originally reported. But the detail describes THREE fixed tests, because http-readiness turned out to have a second marginal case that was never in the original report, and a reader comparing headline to body sees a discrepancy that is really an unstated scope change. These records are read back at session start by their summary line, so the headline is the part that has to survive alone. It now says three fixed, two of them from the original five. No detail changed; the record's content was already right. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JEzkroXdtL9kYo8rW5eZh2

Detailed below.Bundled per AGENTS.md, which asks issue requests to travel with their owning product PR rather than take a ledger-only branch. Each is its own revertible commit, and the ledger commit was pushed only after CI had settled green on the test commit.
Why the test change: this one fails at rest, not just under load
Run on a Windows workstation from the repository root, this file alone, nothing else running:
That is a stronger result than the load-induced failure handled in #2255. It is not a flake to be waited out — the budget is simply too small.
Mechanism. The test server stalls its first two responses (
response.write("partial"), never ended) and ends the third with"ready".waitForHttpReadinessgives every attemptrequestTimeoutMs, and on expiry callsfinish(null)+request.destroy()and polls again. The two stalls are meant to consume the whole budget. The problem is that the same 40ms also bounds the third response, which is healthy: if it merely arrives late, it is destroyed as though it had stalled, the loop polls a fourth time, andexpect(requests).toBe(3)fails with the observed4. Raising the budget cannot weaken the stall path — those responses never arrive at any budget — it only stops a good response being misread as a stalled one. The overall deadline moves with it because two 250ms stalls no longer fit inside 1s.The second test is the same defect from the other side. Every response stalls there, so the deadline alone decides how many attempts fit: 180ms left room for about four, and a single late timer collapses that to one, failing
toBeGreaterThan(1). That was failure #3 of the five originally reported from this workstation, and it recurred across many concurrent copies of this file in a separate run. At 600ms roughly thirteen attempts fit, so the assertion now needs the loop to actually poll rather than to win a race. The deadline is still honoured, still rejects, and the< 2_000msboundedness assertion is untouched and still passes.The four ledger records
#CCZ4HB(review-bot budget, P1) gains a second measurement: every PR opened this session — test(document-viewer): name the cause when render-ahead is never scheduled, and record the five unreproducible Windows failures #2252, test(codex-cloud): budget the shell-policy case for Windows Git Bash spawns #2255, test(http-readiness): widen the millisecond budgets Windows cannot hold, and record this session's findings #2256 — was skipped by CodeRabbit, with the countdown shrinking across it (48 → 32 → 27 minutes). The binding constraint has moved from the rate limit to the organisation spending cap, which is a billing decision no repo gate substitutes for. It also names an interaction worth writing down: the draft-by-default rule guarantees no bot review until someone undrafts, and undrafting mid-CI cancels the run and reds the required aggregate (observed on test(codex-cloud): budget the shell-policy case for Windows Git Bash spawns #2255 and again here). Draft default, review budget and cancel-in-progress churn are one problem seen from three sides.#6GW95D(worktree disk pressure, P2) is re-scoped.

The remaining open item is #2 in the table above:
hosted-migration-role-guard› "accepts the current repository state". It passes now at 1.55s, nowhere near any budget, so the timeout explanation that resolved#1 and #3 does not fit it. It is deliberately left open rather than assumed fixed, and the new record says what to capture if it recurs —git status --porcelain --untracked-files=allandgit ls-files --others --exclude-standardat the moment of failure, because the assertion alone will not identify which entry did it.After this lands:
