- Around line 30-37: Update assertDistFresh and its call in
continuous-test-suite-provider-matrix-cli.ts so the freshness check explicitly
validates dist/cli/index.js, either by extending the helper to accept the CLI
entrypoint or by adding an equivalent targeted check. Preserve the existing
source-versus-distribution freshness validation for the CLI-spawning matrix.

The change is exactly right: a stale dist/ was the one failure mode this CLI-matrix suite exists to catch, and assertDistFresh() closes it without false positives (deterministic mtime compare). Minimal, test-only, no src/ surface touched, no blast radius. No blocking findings.
continuous-test-suite-provider-matrix-cli.ts spawns dist/cli/index.js
for every provider, but never called assertDistFresh(). Its SDK sibling
always has. A dist left over from an earlier checkout therefore made
this suite exercise an old binary silently — and the suite's entire
purpose is catching drift between the library and that binary, which
is precisely what a stale dist conceals. Failures would look like
ordinary provider regressions with no hint the artifact under test was
not the working tree.
Red/green, with no provider calls on either side (--provider=__none__
selects nothing, so the run reaches the guard and nothing else):
release tree, dist made stale → exit 0, suite proceeds
this branch, dist made stale → exit 1, "dist/ is stale — src/ has
changed since the last build"
this branch, dist fresh → exit 0, guard does not false-positive
The third line matters as much as the first two: assertDistFresh
compares mtimes, so a guard that fired on a healthy tree would be worse
than none at all.
Two other claims about this file were investigated and are NOT changed,
because neither survived checking. Both are now recorded in comments so
the next reader does not "fix" them by guesswork:
- The 400-char payload in classifyCliFailure's final throw looks like
the payload-in-assertion-message hazard CLAUDE.md warns about, where
isExpectedProviderError() turns a real failure into a silent skip. It
is not reachable here. The check immediately above already runs the
same predicate over the FULL combined output, so by the time the
payload is embedded the answer is known false for a superset of it;
and slice() yields a prefix while no pattern uses an end anchor or a
lookahead, so truncation can only remove a match, never create one.
Confirmed directly: a marker past 400 chars matches the full string
and not the slice — the safe direction. The comment names what would
break this, namely a future `$`-anchored pattern.
- Replacing the hand-rolled runCli with runCLI from helpers/harness.js
would be a regression, not a cleanup. ProcessResult is
{ stdout, stderr, exitCode } and cannot express "killed for exceeding
its deadline", which this suite needs: a hung provider is a SKIP in a
nightly sweep, not a failure. Folding it into a plain non-zero exit
would turn every wedged upstream into red. Deduplicating these means
teaching runCommand to surface a timeout flag, which touches every
suite that uses it.
Review then found a hole in the guard itself, and it is fixed here too.
assertDistFresh() compared the newest mtime found ANYWHERE under dist/
against the newest under src/, so one freshly written file satisfied
it for the whole tree. That is the right default for the case it was
built for — a dist/ left over from another checkout — but it cannot
see a PARTIAL build, and this suite is exactly where that matters: a
fresh dist/index.js would keep the guard quiet while dist/cli/index.js,
the bundle the suite actually spawns, stayed stale.
assertDistFresh now takes an optional { entrypoints } naming bundles
that must individually be newer than src/. All 56 existing call sites
are zero-arg and keep their behaviour exactly; only this suite passes
dist/cli/index.js. The expensive directory walk is memoised rather than
latched, so a suite naming a bundle is no longer skipped just because
another suite called the helper first — which the old `checked` flag
would have done.
Demonstrated by constructing a partial build (touch a src file, then
touch only dist/index.js, leaving the CLI bundle 30 minutes old):
assertDistFresh() → passes
assertDistFresh({entrypoints:["dist/cli/index.js"]}) → throws
"dist/cli/index.js is stale — src/ has changed since that bundle
was built (newest src 3s ago, dist/cli/index.js 30m ago)"
Controls: with everything freshly built the suite exits 0, and
continuous-test-suite-mcp-infra.ts — an unrelated zero-arg caller —
still passes 97/97, confirming the shared helper change is inert for
the other 55 suites.

Re-approval on current HEAD 4ba85d2 after the entrypoints fix. The author answered the CodeRabbit finding well and the fix lands correctly:
- Partial-build hole closed:
assertDistFreshnow takes an opt-in{ entrypoints }; this suite passesdist/cli/index.js, so a freshdist/index.jscan no longer mask a stale CLI bundle. The directory walk is memoised (not latched), fixing the old one-shot skip for named entries. - Zero-arg callers preserved: all 55 other call sites pass no options (
entrypoints ?? []→ no-op loop), so behaviour is byte-for-byte unchanged. No public surface touched.
No blocking findings. Verdict stands: APPROVE.

The defect
test/continuous-test-suite-provider-matrix-cli.tsspawnsdist/cli/index.jsfor every provider in the matrix, and never calledassertDistFresh(). Its SDK sibling,continuous-test-suite-provider-matrix.ts, always has.So a
dist/left over from an earlier checkout made this suite exercise an old binary silently. That is particularly bad here: the suite exists to catch drift between the library and the shipped binary, which is exactly what a staledist/conceals. Failures would read as ordinary provider regressions with nothing indicating the artifact under test was not the working tree — the failure modedistFreshness.ts's own header describes as "worse than a hard failure".Red / green
No provider calls on either side:
--provider=__none__selects nothing, so the run reaches the guard and then stops.dist/dist/ is stale — src/ has changed since the last buildThe third row carries as much weight as the first two.
assertDistFreshcompares mtimes, so a guard that fired on a healthy tree would be worse than no guard. Both trees' mtimes were restored afterwards and re-verified at exit 0.Two claims investigated and deliberately NOT changed
Both were on my own to-do list for this file. Neither survived checking, so both are recorded as comments in place rather than acted on — the point is that the next reader does not "fix" them by guesswork.
The 400-char payload in
classifyCliFailure's final throw is not the hazard it looks like.CLAUDE.mdwarns that quoting provider output into a thrown message letsisExpectedProviderError()turn a real failure into a silent skip. That is sound in general and unreachable here: the check immediately above already applies the same predicate to the full combined output, so by the time the payload is embedded the answer is known false for a superset of it; andslice()yields a prefix while no pattern in the predicate uses an end anchor or a lookahead, so truncation can only remove a match, never create one. Verified directly — a marker placed past 400 characters matches the full string and not the slice, which is the safe direction. The comment names the thing that would break this: a future$-anchored pattern.Swapping the hand-rolled
runCliforrunCLIfromhelpers/harness.jswould be a regression.ProcessResultis{ stdout, stderr, exitCode }and has no way to express "killed for exceeding its deadline". This suite needs that: a provider that hangs is a SKIP in a nightly sweep, not a failure, and folding it into a plain non-zero exit would turn every wedged upstream into red. Deduplicating them properly means teachingrunCommandto surface a timeout flag, which touches every suite that uses it — a separate change with a much wider blast radius.Scope
One file, test-only. No
src/change, sodocs/apiand thedocs-siteartifacts are untouched and unaffected — confirmed bygit statusover both paths after the edit.check:tools-testsandlintboth pass.What this does not do
This suite still runs in no workflow. Registering a
test:script does not make CI run it, and that gap is tracked across all the orphaned live suites in #1684 — so this guard protects anyone running the suite by hand, which is currently everyone who runs it at all.Summary by CodeRabbit
