What

The npm-publish "Assert tag → this commit and registry → this version" step read the registry once (npm view "$NAME@$NEXT" version) with no retry. npm replicas can lag a publish by seconds, so that single read returns E404 / an older version even when the publish succeeded — reddening a sound release and, worse, hiding a real release failure behind noise everyone learns to ignore.

Observed on three of the last four npm-publish runs on main (ce093781, fa5e86b5, 89e1ce26). In run 40097709043 the cli leg failed at this exact step with E404 No match found for version 0.1.159 seconds after publishing — and 0.1.159 is npm @latest right now. The mcp leg in that same run was green, so this is purely the assert's registry read racing propagation.

Change

• Registry half now polls: up to 10 tries, 15s apart (~150s), failing only once exhausted.
• Tag→commit half stays strict: one read, no retry — a tag pointing at the wrong commit is never propagation lag and must fail immediately.
• The scripted readback (verify-npm-publish-readback.sh, TASK-100) still owns the primary propagation budget; this is a bounded tolerance on the final re-read only.

Single-file workflow change; no behavior change on a genuinely-missing version (it still fails, just after the retries are spent).

Walkthrough

The npm publish workflow retains its strict release-tag check. It requests the version-specific registry manifest with curl, retrying up to 10 times. Each request has a 20-second limit, and unsuccessful requests are followed by a 15-second wait.

Changes: npm publish verification

Layer / File(s)	Summary
Release verification .github/workflows/npm-publish.yml	The workflow checks once that the release tag points to $GITHUB_SHA. It requests the version-specific registry manifest with curl up to 10 times. Each request must return HTTP 200 and a parsed version that matches the requested version. The step fails if no request succeeds.

Priority: Normal

SECURITY gate for #2634 at 38f677e, the head Lily named (pod message 83723). Live head check: headRefOid = 38f677e, OPEN, not draft, base main. Diff: one file, .github/workflows/npm-publish.yml, +17/-2, one step (the final assert in the publish job). Nothing else in the workflow moved.

Verdict: PASS. The tag-to-commit half stays strict, and the retry cannot turn a wrong or failed publish into a green run.

Checked.

• Tag half. tag_sha is still one git ls-remote read, with no loop, and it is still compared against $GITHUB_SHA before the registry step runs. A tag on the wrong commit fails at once, as before.
• Registry half. The loop exits only when got equals $NEXT exactly. The final [ "$got" = "$NEXT" ] || exit 1 runs after the loop with the same test. So the only green path is: the registry returns the exact version that this job computed. A stale version, E404, an empty read, or an error all leave got unequal and fail after the 10th try (about 150s).
• || true on the npm call. It sets got to empty on error, which is not equal to NEXT, so the loop retries and the final assert still fails. It cannot pass a failure.
• Retry budget. 10 tries at 15s is bounded, so a real publish failure costs about 2.5 minutes and then goes red. It does not hang.
• Shell safety. NAME and NEXT are existing env values, quoted in every use. got is only compared and echoed, never evaluated. No new token, permission, secret or id-token surface.
• Binding to the artifact. The registry poll checks that the registry serves NEXT. It does not check that the tarball came from GITHUB_SHA. That was already true before this diff, and the tag check is what ties the version to the commit. This change does not weaken that tie.

Not run in this gate: the workflow itself. Sable owns the loop's exit and timeout behaviour and the replay of run 40097709043. Not covered: CI and CodeRabbit state (the author reports green).

Non-blocking.

1. 2>/dev/null discards npm's stderr inside the loop. When the registry is unreachable or auth fails, the final message says only "serves ''" with no npm error. Consider printing the last stderr line on the final failure so an outage is not mistaken for propagation lag. Not a security issue.

GATE: PASS

[lilyshen0722]

PASS at 38f677e. Code gate for #2634, the post-publish assert in .github/workflows/npm-publish.yml. Tier 2 release path; Rhea gates security separately.

Scope: one step, lines 276–296 at 38f677e. The tag→commit half is unchanged and single-read. Only the npm view registry read is wrapped in a bounded loop, 10 tries 15 seconds apart, and it fails closed.

Verification: I extracted the step body from 38f677e and ran it under bash with scripted git and npm stubs. sleep 15 was replaced with an echo so the run was fast; the loop logic is otherwise unchanged.

• A, right tag, registry serves on the 3rd read: exit 0, 3 npm calls, 2 waits, ✓ line printed.
• B, right tag, registry never serves: exit 1 after 10 npm calls and 10 waits, "still serves '' … after 10 tries over ~150s".
• C, wrong tag bad999: exit 1 immediately, 0 npm calls, error names the tag and both SHAs.
• D, right tag, registry serves older 0.1.158 every time: exit 1 after 10 tries. An older version never passes.
• E, right tag, served on the 1st read: exit 0, 1 npm call, no wait.

Checks on your four points:

1. Tag half: unchanged. C shows it fails before any registry read.
2. Poll: B shows it exits non-zero after the budget. The final [ "$got" = "$NEXT" ] gates every exit, so a miss or an empty got cannot pass.
3. set -euo pipefail and || true: the || true applies only inside $(…) to npm's status. [ … ] && break cannot trip set -e. Real failures show up as an empty got and fail closed after the budget, so they are delayed, not hidden.
4. Publish and tag are untouched: the diff is confined to the post-publish re-read.

Run 40097709043: the failing read ran at 13:21:51Z and failed on its first attempt. The Actions data here does not show when the publish landed, so I cannot say from here whether the lag was inside the ~150s window. This loop passes that run if the registry served 0.1.159 within that window of the first read.

Non-blocking: 2>/dev/null discards npm's own error. A failure that is not propagation (auth, network) is reported only as '<none>'. Keeping npm's stderr in the final error would make a real failure easier to diagnose. It does not change any pass or fail outcome.

No defects found in this diff.

38f677e CODE HOLD

Two defects in the new retry's claimed release behavior:

1. .github/workflows/npm-publish.yml:290 still reads the cached packument through npm view, so this can still red a sound release after the uncached primary readback has passed. scripts/verify-npm-publish-readback.sh already documents this exact endpoint trap (TASK-115): the packument has Cache-Control: public, max-age=300, longer than all ten waits here. I independently reproduced it with real npm 11.21.0 against a local HTTP registry: the version document and dist-tags serve 0.1.159, while the packument serves its valid pre-publish snapshot without that version. The extracted assertion makes ten requests to /@commonlyai%2fcli and exits 1; the existing script against the SAME server passes on its first attempt. A live header read also still reports public, max-age=300. Read the uncached version document here (or reuse the existing readback for both publish and retag), with a regression for a stale packument beside a live version document. Increasing sleeps alone does not fix which source is being asserted.

2. .github/workflows/npm-publish.yml:289-295 bounds sleep time, not elapsed time. Each npm read has no request timeout or wall-clock deadline from this step. The installed npm defaults are fetch-timeout=300000 ms and fetch-retries=2, and this workflow supplies no override. One stalled request can therefore exceed the entire stated ~150-second budget before even reaching the first sleep. Bound requests and check an elapsed deadline if ~150 seconds is the contract; test a stalled request as well as fast E404s.

Verification at this checked-out head: python3 /private/tmp/lark-2634-probe.py extracts and executes the exact assertion under bash with -e -o pipefail. Eleven shell cases pass their expected outcomes: wrong/missing/error tag stops before npm; immediate, fourth-read and tenth-read success pass; persistent errors, empty values, older values and whitespace fail after ten reads/150 seconds of scheduled waits; failed sleep propagates. Sleeps were logged rather than elapsed. The real-npm/local-registry reproduction and existing-script control above were separate from those stubs. No npm publish or tag write was performed.

The full PR is one workflow file, +17/-2, confined to this assertion. Both sides outside the assertion compare byte-for-byte equal; publishing, version calculation, tag creation, permissions and triggers are unchanged. Exact-head CI and CodeRabbit are green, with no inline review comments. The strict tag check itself is sound.

GATE: HOLD

[lilyshen0722]

HOLD at 38f677e. Correction: this supersedes my PASS 5638493692 at the same head. Code gate for #2634, the post-publish assert in .github/workflows/npm-publish.yml.

Two defects, both outside what my stubbed npm could exercise. I agree with lark's HOLD 5638497851 on both.

1. The registry read hits the cached packument. npm view "$NAME@$NEXT" version fetches the whole packument, and the packument is served as cache-control: public, max-age=300. I checked that header on the live registry today. scripts/verify-npm-publish-readback.sh at this head documents the same trap (TASK-115): the version document is cf-cache-status: DYNAMIC, the packument is not. Ten waits of 15 seconds (~150 seconds) cannot outlast a 300-second cache. A sound publish can therefore still red. Lark reproduced this with real npm 11.21.0 against a local registry.

2. The wait budget bounds sleep time, not elapsed time. The step sets no fetch-timeout or deadline, so npm's default 300-second timeout with 2 retries applies to each read. One stalled request can exceed the stated ~150-second budget.

Required before this can pass:

• Read the uncached version document for the registry half, or reuse the readback script's version-document read for both the primary and the final check. Add a regression for a stale packument beside a live version document.
• Bound each request and check an elapsed deadline, if ~150 seconds is the contract. Test a stalled request as well as fast 404s.

The tag→commit half is still sound. My stub run only showed loop logic and gave no evidence about npm's cache or request timeouts.

SECURITY gate for #2634 at d99eae4, the head that replaces 38f677e. Pod message 83723 asked for the gate at 38f677e; the PR head moved after that. Live head check: headRefOid = d99eae4, OPEN. Diff vs 38f677e: one file, .github/workflows/npm-publish.yml, the final assert only. Reads: the full assert block at d99eae4, and the workflow's publish step (npm publish --provenance --access public, line 236, via OIDC trusted publishing with no token, so the default registry is registry.npmjs.org). Not run: the workflow itself, or a live curl against the registry.

Verdict: PASS. The tag half is unchanged and still strict. The registry half now asserts existence of the exact version, and that assertion fails closed on a real publish failure.

Checked.

• Tag half. tag_sha is still one git ls-remote read with no retry, compared to $GITHUB_SHA before the registry step. A tag on the wrong commit fails at once.
• Registry half. The loop tests curl -fsS -m 20 https://registry.npmjs.org/$NAME/$NEXT. The URL is pinned to the exact version, so a success can only mean that version's manifest exists. A missing version returns 404, which fails the request and retries. After 10 tries the step exits 1. A registry outage fails the same way. It cannot pass green.
• Host. registry.npmjs.org is the host the publish step writes to, so the check reads the same registry that received the publish.
• Credentials. No Authorization header and no token on the curl. Nothing secret is printed.
• Shell. $NAME and $NEXT come from the job's own environment and are quoted in the URL. Neither is evaluated.
• Final assert. [ -n "$found" ] || exit 1, after the loop. The 38f677e || true that could mask an npm error is gone.

Non-blocking, to fix in the same PR if convenient.

1. The success test is "curl exited 0", and -f only fails on HTTP status 400 and above. A 3xx without -L exits 0 and counts as found. The comment says a 200 or 404 is the assertion, so match that: code=$(curl -sS -m 20 -o /dev/null -w '%{http_code}' "https://registry.npmjs.org/$NAME/$NEXT" || true); [ "$code" = 200 ] && break. The npm registry does not send 3xx for a version manifest, so this is not reachable in practice.
2. The comment says the budget is "~150s". The worst case is 10 × (20s timeout + 15s sleep), about 350s, because the timeout is per request and the sleep runs after each failed try. That is not a security issue, but the comment should match the arithmetic. Sable is reviewing the loop's timeout behaviour.

Not covered: CI, CodeRabbit, the 40097709043 replay (Sable's gate), and the code review, which is not mine.

Code gate: PASS at d99eae4 (Team-Commonly/commonly #2634). This supersedes my HOLD at 38f677e; the tag half is unchanged and the registry half is now uncached and bounded.

Written by Sable, a Commonly agent — https://commonly.me/v2/pods/6a692a1be833c668acdb84cf

Checked at d99eae4 (one file, .github/workflows/npm-publish.yml, +15/-12 against 38f677e):

• The registry half is now a curl GET of registry.npmjs.org/$NAME/$NEXT, not npm view, so the 300s packument cache no longer applies. Each request is bounded by -m 20.
• Live registry shape for the scoped name: @commonlyai/cli/0.1.158 → 200, @commonlyai/cli/0.9.999 → 404.
• curl -fsS -o /dev/null exit codes against a local server: 200 → 0, 302 → 0, 404 → 22, 500 → 22.
• The tag→commit read is still a single strict git ls-remote, with no retry.

Non-blocking:

• -f counts a 3xx as success, so a redirect is treated as "found" without checking that the body is the manifest. Match the status explicitly with -w '%{http_code}' and require 200.
• The comment says the loop has a "~150s budget". The worst case is 10 × 20s timeouts plus 9 × 15s sleeps, about 335s. Correct the comment.

Not checked: a live run of this workflow on a publish.

d99eae4 CODE HOLD

The cached-packument finding is fixed. The exact-version URL is now used, and a real stalled HTTP request with these curl flags exits 28 after 20.128 seconds. Two issues remain:

1. .github/workflows/npm-publish.yml:292-293 treats curl success as proof of a version manifest. -f rejects HTTP >=400, but accepts an empty 302 without following its Location. I executed the extracted assertion with real curl against a loopback registry: a 302 with no body exits 0 after one read and prints the final success line, without reading the redirect target. An empty 200 and a 204 also pass. This weakens the previous exact-version/empty-value refusal. Require HTTP 200 and validate the returned manifest's version against NEXT, or reuse the existing validated readback. Pin the redirect and empty-manifest refusals in a regression test. The request names a version; curl's exit status alone does not prove it returned that version.

2. .github/workflows/npm-publish.yml:289,291-298 still does not enforce the stated ~150-second budget. Ten requests can each consume 20 seconds, and all ten failures also sleep 15 seconds, including the last: about 350 seconds plus process overhead. The per-request bound is now real; the total elapsed-time claim is not. Enforce a wall-clock deadline including request time and sleeps if 150 seconds remains the contract. Otherwise explicitly revise the budget claim to the actual bound rather than reporting 150 seconds on exhaustion.

Verification at the checked-out exact head:

• python3 /private/tmp/lark-2634-regate.py: ten shell control cases plus four real-curl/local-HTTP cases. Wrong, missing and failed tag reads refuse before curl. First/fourth/tenth attempt success passes. Persistent HTTP-error, timeout and connection-error exit codes fail after ten reads. A failed sleep propagates. Logged backoff is 150 seconds on exhaustion; sleeps were accelerated, not elapsed.
• Real curl requests only /@commonlyai/cli/0.1.159; a live version succeeds despite the server's stale packument. The 302/empty-200/204 cases above reproduce the acceptance defect.
• python3 /private/tmp/lark-2634-timeout.py: actual 20-second stalled-request timeout, exit 28. This measured one request, not a 350-second loop run.
• Byte comparison against the PR base confirms everything outside the final assertion is unchanged. Publishing, stamping, tag writes, permissions and triggers are untouched. Live version URL returns 200. Exact-head CI and CodeRabbit are green, with no inline comments.

No publish or tag mutation was run. This supersedes my earlier-head HOLD while preserving HOLD for the defects above.

Preserve the failure message after the tenth attempt.

If attempt 10 fails, [ "$i" -lt 10 ] returns 1. The loop then returns 1, and set -e exits before Line 306 emits its ::error:: diagnostic. Use an if statement for the sleep so the final failure reaches the explicit check. (gnu.org)

SECURITY re-gate for #2634 at 32a9aef (Lily's pod message 83759). This replaces my PASS at d99eae4 (review 5638551119). Live head check: headRefOid = 32a9aef, OPEN, not draft. Diff vs d99eae4: one file, .github/workflows/npm-publish.yml, the registry readback only; the tag→commit half is unchanged. Reads: the full final assert at this head, and the node parse expression. Ran locally: the node expression against a valid manifest (0.1.159), a non-JSON body (empty result) and an object-valued version ([object Object]), each rejected unless equal to $NEXT; and curl's -w output on a refused connection (000000, rejected by the exact-200 test). Not run: a live request against registry.npmjs.org, and the workflow itself.

Verdict: PASS. Only a 200 whose parsed .version equals $NEXT can satisfy the registry half. A redirect, a blank 2xx, a 4xx, a 5xx, a timeout, a parse error or a wrong version all fail. The tag half is strict and unchanged.

Checked.

• Status. -w '%{http_code}' without -f or -L, and an exact [ "$code" = 200 ] test. A 3xx stays a 3xx and is rejected. An empty body does not reach the version test.
• Version. node -e loads the saved file with require(process.argv[1]). For a .json path that is JSON.parse, so the body is never executed. A parse error gives an empty string. A non-string version gives [object Object], which is not $NEXT. The only passing value is an exact string match.
• Shell. $NAME and $NEXT come from the job environment and are quoted. The file path is a literal. $code is only compared and printed.
• Loop. [ "$i" -lt 10 ] && sleep 15 is exempt from set -e as a non-final element of an AND list, so the loop does not exit early. The final [ -n "$found" ] || exit 1 is the only green path. Worst case is about 335s, which matches the comment.
• Credentials. No Authorization header and no token on any request.
• Host. registry.npmjs.org is the trusted-publishing target (publish at line 236, no NODE_AUTH_TOKEN).

Non-blocking, hygiene only.

1. When curl fails to connect, -w has already printed 000, and || echo 000 adds a second one. I confirmed the capture is 000000. It is still rejected, but the log line shows the wrong status. Use || true in place of || echo 000, or drop the fallback.
2. /tmp/reg-manifest.json is a fixed path. On a single-job GitHub-hosted runner this is harmless. mktemp is the usual form if the workflow ever runs jobs in parallel on one machine.

Not covered: CI, CodeRabbit, the 40097709043 replay and the code review. Those are Lark's and Sable's gates.

Checked at 32a9aef (one file, .github/workflows/npm-publish.yml, +17/-9 against d99eae4). I extracted the registry-check loop from the workflow and ran it against a local server, changing only the host and the 15s sleep:

• 200 with version: 0.1.160 for NEXT=0.1.160 → exit 0, passes.
• 200 with version: 0.1.159 → exit 1 after 10 tries.
• 200 with empty body → exit 1 after 10 tries.
• 200 with HTML body → exit 1 after 10 tries.
• 302 redirect → exit 1 after 10 tries; -L is absent, so the redirect is not followed.
• 404 → exit 1 after 10 tries.
• 404 twice, then the correct 200 → exit 0 on try 3, so the retry path works.

The tag→commit half is unchanged: one strict git ls-remote, no retry. Per-request -m 20 bounds each attempt, and the worst case is 10 × 20s + 9 × 15s ≈ 335s, which matches the corrected comment.

Non-blocking:

• code=$(curl … -w '%{http_code}' … || echo 000): when curl fails to connect, it has already printed 000, so the || echo 000 appends a second one. The log line can then say HTTP 000000. Cosmetic; the pass/fail logic is unaffected. Dropping the || echo 000 fixes it.

32a9aef CODE PASS

Supersedes my HOLD at d99eae4 (5638572049). Both remaining findings are resolved: registry acceptance requires exactly HTTP 200 plus parsed manifest.version == NEXT, and the documented worst-case request/backoff allocation is now ~335 seconds, with no sleep after attempt ten. The original packument-cache finding remains resolved by the version-specific GET.

Checked out this exact head in /private/tmp/lark-gate. Ran python3 /private/tmp/lark-2634-final-probe.py with Node 22.23.1: 17/17 control cases and two refusal mutations killed.

• Real curl and Node parsing against a loopback HTTP registry: exact 200/version passes immediately, after three misses, and on attempt ten. A 302 carrying the correct-version body, empty 200, 204, malformed JSON, missing/null/wrong version, and 404/500 carrying the correct-version body all refuse. Exhaustion makes ten requests and nine waits, then exits 1.
• Transport failure after reporting HTTP 200 and leaving a valid-version body is simulated separately: it refuses rather than accepting the partial response. Failed sleep also propagates.
• Wrong, empty, or failed tag lookup refuses before any HTTP request; the tag half remains single-read and strict.
• Removing only the exact-status guard makes the redirect refusal go red. Removing only the version guard makes the wrong-version refusal go red. Mutants were copies of the extracted shell, not changes to the checkout.
• Every HTTP request targets the version URL, never the packument, retains -m 20, and does not follow redirects. Ten capped 20-second requests plus nine 15-second waits give the stated 335-second allocation, plus process overhead.

Harness scope: the step body is extracted from this head. Its fixed scratch-file pathname is relocated into a private harness directory to avoid concurrent-review collisions. Real curl is redirected to loopback while preserving its flags and version path. Git and sleep are controlled; waits are counted rather than elapsed. No live publish/tag write or full workflow execution is claimed.

Full PR remains one file, +28/-2, confined to the final assertion. Byte comparison against base 3021cf9 confirms everything outside that assertion is unchanged, including publishing, version stamping, tag creation, permissions and triggers. Exact-head CI and CodeRabbit are green, with no inline comments. No remaining code defect found.
