The validator adds delivery-evidence enforcement, but valid deliveries using an empty repository configuration may be blocked and malformed CI evidence can terminate with an unhelpful error. These are bounded validation-path issues that should be addressed before broad reliance on the new tool.

An empty JSON object config is rejected.
not overrides is true for {}. A target repository that commits .github/pr-standards.json with {} is a valid "no overrides" configuration, but every delivery then fails with "must contain a JSON object". Line 70 already rejects empty content. The two isinstance checks are also redundant, because not isinstance(overrides, dict) already excludes lists.

Reviewed head: ddf69ac61e9d43e843749c3855ef5f3ec20f0bde
Council findings verified against the code (not just the hunks). Two confirmed security bypasses remain open in the validator, plus a structural PR-standards violation I can't fix by pushing. I pushed nothing this cycle.
Why no fixes from me: this file has already had four prior hardening passes in this same PR (369eb17, fc47ed6, c42587e, 122f9a0, af56172) all aimed at closing forged-setup/compound-shell gaps, and a bypass still slips through (finding 1). Per the loop guard, I'm flagging rather than adding a fifth regex patch to the same code. Separately, the diff is already far over the 500-line cap, so any push of mine would only worsen a violation I'm not allowed to paper over.
1. Critical — quoted && still forges a lockfile install
parse_bounded_setup_steps (worker-delivery-validate.py:34-42) rejects raw &&/;/|/etc. via COMPOUND_SHELL, then splits on \s*&&\s* — but that split is textual, not shell-aware. echo 'noop && npm ci' contains no top-level compound operator (the && is inside single quotes), so it sails past COMPOUND_SHELL, then gets split into ["echo 'noop", "npm ci'"]. The first fragment matches FORGE_CMD and is discarded; the second, "npm ci'", matches \bnpm ci\b and is accepted as a real install step — even though the actual command only echoes text and never runs npm ci. Traced by hand against the current regexes; not covered by any of the FORGED test cases (which only test unquoted forgery).
2. Critical — bound verify command has no grammar check, and worker-run evals it
validate() only checks that bound_verify_cmd is non-empty and bound_verify_exit == "0" (worker-delivery-validate.py:111-117) — parse_bounded_setup_steps/COMPOUND_SHELL is applied to the setup command only, never to verify. worker-run runs the verify command with eval "$VERIFY" (worker-run:152) and simply records whatever exit code eval returns. So --verify 'false; true' (or false || true) evals to exit 0 in worker-run, gets recorded as BOUND_VERIFY_EXIT=0, and the validator accepts it as a passing verification — with the same compound-shell trick the setup path was specifically hardened against.
3. Major — lockfile requirement is basename-only, ignores directory
worker-delivery-validate.py:144 reduces committed lockfiles to {p.rsplit("/", 1)[-1] ...} — bare basenames, path discarded. The install check (line 152-153) then only asks whether some step matches \bnpm ci\b anywhere, never which directory it ran in. A repo with both a root package-lock.json and backend/package-lock.json collapses to a single "package-lock.json" requirement, satisfied by one root-level npm ci even if backend/ was never installed. The nestedlock test only proves the basename is detected, not that the directory is enforced.
4. Critical (process) — this PR now carries #325's wiring, ~800+ lines over the 500 cap
PR #325 ("[SCR-322] Require delivery evidence before worker completion") targeted base = scr-321-validate-exact-worker-delivery-evidence (this branch), not main, and its merge commit is ddf69ac... — the current HEAD of this PR. That means PR #323, as it will actually land on main, now carries both the #321 validator (its own scope) and the entire #322 worker-run wiring: 7 files, +808/-3 vs the PR body's last self-reported count of 5 files / 515 lines. That is roughly 300 lines further over the 500-line cap than the body admits, and it mixes two issues (#321, #322) into one PR-to-main despite Closes #321 being the only reference. This is exactly the scope violation the scope-lens flagged (worker-run/worker-run.test.sh integration), just arriving via a stacked-PR merge rather than a direct edit.
I can't fix this by pushing — trimming would mean rewriting merged history, and any additive commit from me only deepens the overage. Concrete split for a human: pull the worker-run wiring commits (everything from "Wire worker-run through delivery validator with proof" onward, i.e. the #325 content now folded into ddf69ac) back out of this branch, land the standalone validator (c8fb886..af56172, the PR body's own "515/5 files" snapshot) as #323 first, then reopen the wiring as a fresh PR based on main post-merge so it's counted and reviewed on its own.
5. Minor — proof is stale
The body's "How I verified" section and size claim (Head: 9d554e2 — 515 counted lines / 5 files, marked "held — do not merge") predate the ddf69ac merge entirely and never run or mention worker-run.test.sh (591 lines, part of the current diff). None of the evidence in the PR body exercises the worker-run integration path that's now included.

Critical: this split is textual, not shell-aware. COMPOUND_SHELL (line 18) only rejects &&/;/|/etc. that appear unquoted at the top level of the whole string — but re.split(r"\s*&&\s*", cmd) doesn't know about quoting either. echo 'noop && npm ci' has no top-level compound operator, so it passes the guard on line 38, then splits into ["echo 'noop", "npm ci'"]. The second fragment matches \bnpm ci\b (line 152-153) and is accepted as a real install, even though the actual command only echoes text. This is the same class of bug the last several commits hardened against (shell -c wrap, bare &&/;/|), just via a quoted operator instead. Needs real shell tokenization (e.g. shlex.split plus checking each token isn't itself quoted-and-compound), not another regex case.

Critical: bound_verify_cmd never goes through parse_bounded_setup_steps/COMPOUND_SHELL — only bound_setup_cmd does (line 148). worker-run executes the verify command with eval "$VERIFY" (worker-run:152) and reports whatever exit code that eval produces. So --verify 'false; true' (or false || true) evals to 0 in worker-run and is accepted here as a passing verification, using exactly the compound-shell trick the setup path was hardened against. The same grammar check applied to setup needs to apply to verify.

Major: lockfiles are reduced to bare basenames here, and the install check (below) only asks whether some step matches the tool's install pattern anywhere — never which directory it ran in. A checkout with both package-lock.json and backend/package-lock.json collapses to one "package-lock.json" requirement, satisfiable by a single root-level npm ci even if backend/ was never installed. The nestedlock test only proves detection of the basename, not that installs are scoped to the right directory.

Critical (process): this wiring is #322's scope (PR #325), not #321's. PR #325 targeted base=scr-321-validate-exact-worker-delivery-evidence and its merge commit is ddf69ac, the current HEAD of this PR — so this content landed on #323's branch via a stacked merge rather than main. As a result, PR #323 vs main is now 7 files / +808/-3, far past the 500-line cap the PR body itself flagged at 515/5 files ("held — do not merge until resolved"). I'm not pushing a fix for this: trimming would mean rewriting already-merged history, and any commit I add only deepens the overage. Recommended split: pull everything from the "Wire worker-run through delivery validator with proof" point onward back out of this branch, let the standalone validator (ending at af56172) merge as #323 first, then reopen the wiring as its own PR based on post-merge main.

I pushed one fix this cycle and am blocking on one I could not push.
Critical — still open, could not push. .github/workflows/tests.yml has unresolved merge-conflict markers (<<<<<<</=======/>>>>>>>) committed straight into the file, which breaks YAML parsing and fails every CI run on this branch. I resolved the conflict locally (keep main's merge-throughput-tests step alongside this PR's worker-delivery-validate-tests step, merge both Report the verdict env blocks) and committed it, but git push was rejected: "refusing to allow a GitHub App to create or update workflow .github/workflows/tests.yml without workflows permission". This bot's GitHub App install lacks the workflows scope needed to push changes under .github/workflows/. A human needs to either push my local fix (commit e25765c on this branch, not yet on origin) or apply the equivalent merge manually.
Major — scope mismatch, not fixed (author's call, not mine to delete). The diff ships worker-run + worker-run.test.sh (242 new lines wiring --setup/--delivery-report/--pull/--expected-* into worker-run), but the PR body says exactly the opposite: "The security grammar fix lives here, not downstream in wiring" and "Both must land before #325 wiring." This PR (#323) closes only #321. Per AGENTS.md's "One issue. One PR. One concern," the worker-run wiring is #325's content and should move there.
Major — over the 500-line cap, worse than stated. Current diff: 7 files, ~824 counted lines (numstat: tests.yml 26, worker-delivery-validate 43, worker-delivery-validate.py 246, worker-delivery-validate.test.py 212, worker-delivery-validate.test.sh 2, worker-run 52, worker-run.test.sh 243 — none of these match the repo's lockfile/generated-code exclude globs, so all of them count). The PR body's own count (515/5 files, "held — do not merge until resolved") predates the worker-run wiring; the live diff is further over, not under. I'm not deleting code to force it under cap. Concrete split, in order:
- Drop
worker-runandworker-run.test.shfrom this PR entirely — that content belongs in #325, per this PR's own text. - Even validator-only (the 5 remaining files) is still over cap. Land the author's own proposed split as two stacked PRs: "Core evidence gate" (~490 counted: schema, bound setup/verify, lockfile matching, CI reconciliation, compound-shell grammar, pagination hardening) first, then "Live PR attribution" (~66 counted: draft acceptance, SHA-pinned config, Closes-only enforcement, issues-endpoint guard).
Major — proof gap. ## How I verified names only ./worker-delivery-validate.test.sh (48 passed) and node --test pr-standards.test.mjs (97 passed), evidence captured at head 9d554e2. The PR's actual head (2fcaf14) added the entire worker-run wiring afterward — 52 lines in worker-run plus a new 243-line worker-run.test.sh — and no command in the proof section exercises either. The capture that would settle it: run ./worker-run.test.sh at the current head and paste its pass/fail count into ## How I verified (once the file no longer has the conflict markers blocking CI from doing this automatically).

Reject delivery when the live PR is not open/reviewable, carries wrong or extra closing refs, or uses Close/Fixes instead of Closes. Count size against the target repo pr-standards.json at the PR base ref, not DEFAULT_CONFIG. Also harden lockfile depth, forged setup chains, and binary numstat counting.

…aps in worker-delivery-validate
- treat `||` right-hand branches and command/builtin-wrapped echo as
non-executed, so a forged setup command can no longer fake a lockfile
install
- stop gh_items looping forever when total_count overcounts the items
actually returned by the API
- require unresolved_failures to be a list, so null/0/{} can no longer
be read as "no unresolved failures"
Campaign workers deliver open draft implementation PRs for root signoff; reject closed PRs without forcing ready-for-review or merge. Fetch target pr-standards.json by verified pr_base SHA so a moved branch cannot change counted policy after PR metadata is read. Verify the expected issue through the issues endpoint and reject pull_request objects.
Treat bash -c wrappers like bare echo forges so a quoted npm ci cannot satisfy lockfile install validation.
Replace operator-splitting with explicit &&-only steps so semicolon and or-chained setup receipts cannot fake lockfile installs.
Fold compound-shell and shell-wrap rejection into the native #321 validator with all 48 regression cases; tighten setup grammar errors and test harness duplication so the security fix stays upstream of wiring.
* Wire worker-run through delivery validator with proof Require bound setup/verify receipts and delivery validation before worker completion, with 20 integration tests and CI. Closes #322. * fix: cover --setup failure paths in worker-run tests Add the missing --setup failure and --setup+worker failure test cases, mirroring the existing --verify coverage. * Update delivery integration stubs for draft PR acceptance Wire worker-run end-to-end tests through the corrected validator: stub issues endpoint, PR attribution, and SHA-pinned pr-standards config. * Reject skipped-install setup receipts in worker-run wiring Add the end-to-end integration case for false && npm ci; true so wiring tests prove the upstream validator gate blocks zero-install setup receipts.
The branch merged main while #325 was merging and committed the conflict markers literally, so the workflow never parsed and the tests check never reported. Keep main's merge-throughput block and the branch's delivery-validate step; no new behaviour.
|
Stale-PR sweep update: rebased onto current main, reworded the flagged commit to drop the bot trailer (message only, tree untouched), and resolved committed conflict markers in tests.yml left by the Sep 5 main-merge (kept main's merge-throughput block plus this branch's delivery-validate step; YAML parses again, so the tests check should report now). Verified locally: worker-delivery-validate 48 passed, worker-run 23 passed. One blocker remains that I cannot fix without restructuring your change: size is ~811 counted lines vs the 500 cap, and even the validator-only half from your #313 plan lands near 530. The checker offers no waiver (only release promotions are exempt, per #410). This needs you to slim the validator or split it further. Leaving open for you. |

Critical (open)
Forged-setup bypass survives the anti-forgery hardening this PR is built around. FORGE_CMD (worker-delivery-validate.py:16) only denylists echo/printf/print as "this step doesn't really install anything" prefixes. Any argument-swallowing shell builtin slips through: a worker can pass --setup 'true npm ci' (or : npm ci). worker-run really evals that string and gets exit 0 (because true/: discard their arguments and do nothing), so BOUND_SETUP_EXIT=0 is genuine — but no install ever ran. In the validator, segment_installs() (line 31-32) only rejects echo/printf/print, so "true npm ci" is kept as an "install step", and LOCK_INSTALL["package-lock.json"] (\bnpm ci\b) matches the literal substring npm ci inside it. Delivery evidence is accepted as valid even though the committed lockfile was never installed against. This is exactly the class of bug the five prior commits on this branch ("close forged-setup ... gaps", "Reject shell-wrapped forged setup commands", "Reject unsupported compound shell ...") were hardening against, and it reopens it via a different no-op command instead of echo. Suggest replacing the denylist with an allowlist of real package-manager invocations (first token must be npm/bun/pnpm/yarn/cargo), which is what LOCK_INSTALL already assumes.
I did not push a fix: I have no test runner available in this session (no python3/node -e in my tool access here) to verify a change against worker-delivery-validate.test.py's 48 cases, and pushing an unverified change to this exact grammar risks a worse regression than leaving it open.
Major (open) — PR-standards cap
The branch's own "PR standards" check (https://github.com/pooriaarab/scripts/actions/runs/34802944362/job/103849104743) fails: 811 counted lines / 7 counted files vs. the 500-line cap (311 over). I recomputed this independently from git diff --numstat origin/main...HEAD through pr-standards.mjs's own summarizeFiles, and it matches the CI output exactly.
The overage is because this branch also carries worker-run + worker-run.test.sh (295 counted lines) — the already-merged child PR #325 (closes #322) — stacked on top of the #321 validator work (tests.yml + the four worker-delivery-validate* files, ~516 counted lines by itself, still over cap alone). The PR body's own Closes #321 plus "Proposed cap split (held — do not merge until resolved)" section already acknowledges the validator alone needs a 2-way split; but the current head is also carrying #322's wiring, which should never have ridden along on this branch/PR at all since it is its own issue with its own already-merged, already-reviewed PR.
Concrete split, in order:
- Land the core evidence gate (report schema, bound setup/verify, lockfile matching, CI reconciliation, compound-shell grammar, pagination/failure-typing hardening) as its own PR against
main— per the author's own estimate, ~490 counted lines. - Land live PR attribution (draft acceptance, SHA-pinned
pr-standards.jsonfetch, live Closes-only enforcement, issues-endpoint guard) as a follow-up PR — ~66 counted lines. - Land
worker-run+worker-run.test.sh(the #322/#325 wiring) as a separate PR againstmain, based on top of (1)+(2) once merged — do not carry it inside #321's PR.
None of this is something I can fix by editing files — it requires re-cutting branches/PRs, which is the author's call.

Critical: this denylist only catches echo/printf/print prefixes. true npm ci or : npm ci eval to a real no-op exit 0 in worker-run (nothing installs) but this regex doesn't match, so segment_installs() below treats the step as a genuine install and the literal substring npm ci satisfies LOCK_INSTALL. A worker can forge a passed lockfile-install receipt. Consider an allowlist of real package-manager invocations instead of a denylist of fakes.

No regression case here covers a no-op prefix like true npm ci or : npm ci — only echo/printf-style forges are exercised. Worth adding once the denylist above is fixed, so this exact bypass can't reopen silently.

Not merging in this sweep: the latest review (head ed052ea) has an open Critical forged-setup bypass in FORGE_CMD (argument-swallowing builtins like true npm ci pass), the body itself says the PR is held over the 500-line cap pending a split, and the branch now conflicts with main. Needs the author to fix the bypass and split before landing.
Closes #321
What
Standalone
worker-delivery-validateshell/Python with 48 regression cases and CI. Validates tested head, bound&&-only setup/verify receipts (rejects;,||,|, subshells, andbash -cforges), lockfile installs, paginated latest checks, Closes-only refs, open draft PRs with green CI, and bounded config pinned to the verified base SHA — neutral conclusions always block;expected_skippedonly permits actually skipped workflows with a reason.Why
Workers must not claim completion on stale heads, forged setup echoes, compound-shell skips like
false && npm ci; true, optional CI, advisory neutral bots, closed PRs, or policy fetched from a mutable base ref after PR metadata is read. The security grammar fix lives here, not downstream in wiring.How I verified
$ ./worker-delivery-validate.test.sh Results: 48 passed, 0 failed $ node --test pr-standards.test.mjs # pass 97, fail 0Open draft PR with green checks is accepted; closed PRs and pull_request issue objects are rejected.
false && npm ci; trueandbash -c 'echo npm ci'are rejected at the validator layer.Head:
9d554e2— 515 counted lines / 5 files (15 over the 500 cap).Proposed cap split (held — do not merge until resolved)
If root requires strict
<500, split #321 into two stacked validator PRs with source+tests kept together:pr-standards.json, live Closes-only enforcement, issues-endpoint guard.Both must land before #325 wiring; neither may carry the compound-shell fix alone downstream.
