Both CodeRabbit findings addressed — and the first attempt at the argv one introduced a worse regression, so this is worth spelling out. Space-separated option values. The over-correction. Treating every value-taking option as consuming the next argument then swallowed the filter in Only required-value options consume the next argument now. All six boundary shapes are pinned as tests and were verified by running the resolver directly:
The spawn test could pass after a failed run. It asserted only that the output contained Gate: 14438 pass / 2 fail, both inside the repo's load-sensitive flaky pool (built from five base runs on untouched |

The --parallel direction is useful and the focused test-runner suite passes on the current head, but one Bun 1.4.0 argv boundary is still incomplete.
scripts/test.ts does not include --timings in BUN_TEST_OPTIONS_REQUIRING_VALUES. The repository and CI resolve Bun 1.4.0 from package.json, and Bun 1.4.0 declares --timings <STR>.... Therefore resolveBunTestArgs(["--timings", ".bun-test-timings/current.json"]) currently returns --isolate --parallel --timings .bun-test-timings/current.json without ./tests/: the timing file is misclassified as a positional test filter, so the wrapper can silently run no repository suite.
Please add --timings to the required-value set and add a separated-value regression alongside the existing --timeout case. Re-run tests/test-runner.test.ts on the updated exact head. I do not think the PR needs broader lock-policy or test:changed expansion; this is only completing the argv grammar the new resolver owns.

Addressed the Bun 1.4.0 argv boundary in d9cb032. --timings is now treated as a required-value option, with a regression for the separated --timings .bun-test-timings/current.json form retaining ./tests/. Exact-head verification on Bun 1.4.0: tests/test-runner.test.ts passed (7 passed, 2 Windows-only skipped) and typecheck passed. The CodeRabbit thread is resolved; the PR remains Draft until refresh/full-suite readiness is re-established. |

Addressed both outside-diff CodeRabbit findings in 9080018. Bun 1.4.0 documents -c/--config as value-taking base options, so both now consume their separated config path and retain ./tests/. The subprocess fixture now writes a unique marker and the parent test asserts that marker exists, proving the intended fixture actually ran. Exact-head verification on Bun 1.4.0: 7 passed, 2 Windows-only skipped; typecheck passed. |

Addressed on exact head 3187fd4; the PR remains draft pending readiness and full exact-head CI.
Opens the docs-only cycle for the next release train. The planning note this started from targeted v2.31.1; that baseline is void because v2.32.0 shipped from main on 2026-08-24. This unit re-derives the baseline from live git state and plans the train as v2.32.1, bugfix-only. The first draft got the branch relationship wrong: it read a one-way --is-ancestor result as divergence. An independent audit re-ran both directions and dev turns out to be an ancestor of main, 0 ahead and 27 behind, with a one-line tree delta. wp1 is therefore a fast-forward, not a backmerge, and the correction is recorded in the document rather than quietly fixed. Three audit rounds moved two other things. lidge-jun#2427 was reordered from first to last: changing the test runner before the runtime fixes would make every later failure ambiguous between a real regression and parallel-execution flakiness. And lidge-jun#2472's regression got its own work-phase (wp9) once the audit pointed out the plan had made it a mandatory gate while assigning nobody to write it. Contents: 000 baseline/scope/roadmap, 001 verbatim reviewer-lane evidence, and one diff-level decade doc per implementation phase (010 wp1, 020 wp3/lidge-jun#2483, 030 wp4/lidge-jun#2481, 040 wp5/lidge-jun#2473, 050 wp6/lidge-jun#2477, 060 wp7/lidge-jun#2476, 070 wp2/lidge-jun#2427, 080 wp8 freeze, 090 wp9/lidge-jun#2472).

Deferring this from the v2.32.1 hotfix train — not rejecting it. The parser work is sound and the speedup is real; the reason is narrow and I want to hand you the data rather than just a verdict. The bound helps, and it is measurably better than unbounded. I ran the full suite five times across two heads on an idle machine:
Against roughly 560s serially, so the speedup is not in question. Your four-worker bound clearly reduces the failure rate — but it does not remove it. What makes this a deferral. Four different tests have failed intermittently across those runs — An independent reviewer also had one run stop producing output for ten minutes without a terminal summary, and identified a concrete mechanism worth chasing: So these are pre-existing latent order dependencies that parallelism exposes rather than defects this PR introduces. That is a good thing to have found — but it means the runner currently converts a deterministic gate into a probabilistic one. Why that specifically blocks a hotfix train. This release candidate is about to be frozen, and the freeze gate is a full-suite run. Every remaining criterion depends on that run meaning something. A verification instrument that fails ~1 in 3 for unrelated reasons would make the freeze evidence unfalsifiable — a red run could not be distinguished from noise, which is exactly the attribution problem that moved this PR to last in the train rather than first. What would land it. Fix or quarantine the handful of order-dependent tests — the shared- Keeping this open and unblocked; nothing in the v2.32.1 train depends on it. |
The readiness report freezes dev at faaa78d with the verdict GO, and records the audit that got it there: the first freeze at 02c302a was rejected, correctly, on three counts. Two of the three unresolved review threads it found were live defects that had been opened minutes before their PRs merged and so were never addressed — a malformed namespace authorizing a tool alias, and the snapshot fast path never restoring broadened permissions on a file that holds request and response bodies. Both are fixed and both needed a second pass, because the first fix for the namespace case was itself incomplete against a pre-flattened wire name. The third finding was the fairest: the full-suite gate was red and the report argued an exception for it. Arguing an exception in the document that reports the result is gate-weakening after the fact. The gate is now decomposed the way CI actually partitions the suite, and passes in that form: 14565 pass across the general batches, storage-policy green in its own job, with the single api-usage failure proven identical on the untouched pre-train baseline. Also records the two units that closed without merging. #2472 is NOT_REPRODUCED: a regression was written, passed, and then deleted once review showed it pinned the pre-execution announcement path rather than the post-execution loss the issue describes. #2427 is deferred on five runs of data — four different tests flaked, each green in isolation — because a runner that fails one run in three would make the freeze gate itself unfalsifiable.
…ing as hung `bun run test` spawned `bun test --isolate ./tests/`. With `--isolate` and no `--parallel`, Bun re-evaluates the module graph once per file on a single core. Past ~900 files that stops looking slow and starts looking hung. Measured on this tree (902 files): without --parallel 1 h 29 m, zero output, ~57 % CPU, 8.5 MB RSS, killed with --parallel ~110-190 s, 10x PARALLEL The failure mode is what makes this worth fixing rather than documenting: there is no progress output, one core is pinned, and RSS stays tiny, so it reads as a deadlock. A contributor's reasonable conclusion is that the suite is broken. The stale "normally runs in about 210s" warning is updated for the same reason — that number predates the file count that made the flag necessary. `resolveBunTestArgs` is exported and pinned by tests so the flag cannot be dropped again silently, including the two easy-to-regress cases: a caller supplying `--parallel=N` must not be overridden, and an option-only argv such as `--timeout=30000` must still count as a full-suite run and keep `./tests/`. Gate: 14436 pass / 2 fail; both also fail on untouched upstream/dev at this commit (baseline: 4 fail, a superset). Zero regressions. Note on scope: this is the smallest change that makes the suite runnable. Two adjacent changes are deliberately left out and will be proposed separately — narrowing the exclusive-run lock to full-suite runs (a behavior change that lets two focused runs share one sandboxed HOME), and a `test:changed` script with the contributing-guide updates that go with it. Separately and not addressed here: `tests/key-login-live-update.test.ts` fails standalone and serially on a clean tree, so every full run is red by at least one test regardless of this change.
Two review findings. hasCliFlag/isFullSuiteRun read the whole argv, so `test -- --parallel=2` suppressed the default --parallel even though everything after -- is passed through, and a bare - was classified as an option so `test -` was treated as a full-suite run. The tests also asserted only resolveBunTestArgs output: reverting the spawn call to a hardcoded argv left every assertion green. A spawn test now runs the wrapper against a non-matching filter and asserts bun reports PARALLEL.
Two CodeRabbit findings, plus a regression the first attempt introduced. isFullSuiteRun read a space-separated option value as a file filter, so `bun run test --timeout 30000` silently stopped being a full-suite run and dropped ./tests/. Bun 1.4.0 accepts that form. The first fix over-corrected: treating every value-taking option as consuming the next argument swallowed the filter in ["--parallel", "tests/foo.test.ts"], so a focused run became a full-suite run — worse than the original bug, and silent. --parallel, --changed, --timings and --coverage take OPTIONAL values, which Bun expects attached with =. Now only required-value options consume the next argument, and all six boundary shapes are pinned as tests. The spawn test also asserted only that the output contained PARALLEL, so it could pass after a nonzero wrapper exit; it now asserts exitCode 0 first, against a real fixture file so a successful run is meaningful.

After lidge-jun#2427 landed, rebase this policy onto the current wrapper instead of stacking the old serial runner. --changed=dev resolves upstream/dev, origin/dev, then local dev through git merge-base HEAD <ref>, rewrites the Bun filter to that SHA, and fails a silent empty selection when the diff is non-empty.
