🤖 Review — preserve overlap checks on dispatch
This PR extends the overlap detector to run on a bare git ref (--ref <sha> --base dev --dry-run) so a dispatch can check a branch that isn't a PR, sends fork and dependabot PRs down the --dry-run path so they never try to post a comment, and wraps both the helper unit tests and the detection run in JUnit reports. All of that reads correctly, and the fork/dry-run split is the right call.
One thing to reconsider about how the step can now fail, and one test gap.
🟠 Should Fix
🟠 The overlap step no longer has continue-on-error: true, so an infrastructure hiccup in a check that is advisory by construction can now red the PR — and its most likely failure is routine, a push landing while the check runs (.github/workflows/pr-overlap-check.yml:42).
Outside the diff range
🟡 ranges_overlap (detect_overlaps.py:952, unchanged by this PR so I can't anchor on it) is the one place the 37-test suite doesn't guard. Mutating <= to < — which stops touching ranges from counting as an overlap — leaves all 37 tests green. Concretely that's two PRs both editing exactly line 100 of one file: range_a = range_b = (100, 100), 100 < 100 is false, no overlap reported, silently. The shipped code is correct; nothing pins it. Two boundary cases close it:
def test_touching_ranges_overlap(self):
self.assertTrue(ranges_overlap((100, 100), (100, 100)))
self.assertTrue(ranges_overlap((1, 5), (5, 9)))For the record, since it's the file this PR grows most: 3 mutations, 1 killed (fetch_ref_details returning an empty file list → 1 failure), 2 survived (the one above, and dropping the provide exactly one of pr_number or --ref guard).

the rename from/rename to handling to preserve the source path independently
when paths contain spaces and shlex.split produces multiple tokens. Ensure
rename from records header_old_path even without a current_file, and rename to
uses that recorded source to populate old_path and file_aliases for overlap
detection.
- Around line 1502-1512: Update get_pr_files() to handle pull requests whose
changedFiles count exceeds the REST API’s 3000-file cap without raising an
uncaught OverlapInfrastructureError. Use an authoritative uncapped file
inventory when available; otherwise mark the inventory as bounded or unavailable
and let the remaining overlap workflow continue without claiming completeness.

Learning: In `.github/scripts/detect_overlaps.py`, `get_pr_files` must fail closed when GitHub cannot provide a complete pull-request file inventory. The overlap detector must not accept the GitHub REST API's first 3,000 file paths as complete or report a partial overlap result. Support for pull requests with more than 3,000 changed files requires a separate complete inventory source, such as local Git.

…ispatch Three conflicts, each two features colliding rather than one edit winning. detect_overlaps.py: took this branch's `get_pr_diff`. Both sides fix the same `gh pr diff` 406 above 300 files; the base returned an empty diff and reported file overlap only, this branch falls back to local git plumbing and computes the real one, so it is a strict superset. run_unittest_junit.py: kept both. This branch's tag selection and skip policy, the base's XML sanitization — and the two compound, because the policy writes unittest's coloured detail into the report for every disallowed skip. pr-overlap-check.yml: kept both directives. `if: !cancelled()` and `continue-on-error` are orthogonal — one decides whether the step runs after a failed unit-test step, the other keeps a detector failure out of the merge queue on the PR path, where it fails 14 of 25 runs.

🤖 Review: preserve overlap checks on dispatch
Looks good to me — no blockers, no should-fixes. The headline is that this fixes a failure happening right now: 11 of the last 25 pull_request overlap runs exit 1 behind their continue-on-error guard, every sampled one on PullRequest.diff too_large while fetching another PR's diff for comparison. get_pr_diff's new fallback to local git plumbing is what fixes that, and it covers both call sites — the PR under test at detect_overlaps.py:166 and the other-PR path at :475, which is the one actually failing.
That is a better fix than the one it supersedes. The base branch had get_pr_diff return an empty string on a gh failure and report file overlap only; this computes the real diff instead, so the report stops silently degrading.
The other failure class is handled too: READ_ONLY_PR sends fork and dependabot PRs down --dry-run, which is right, because those carry a read-only token and the posting step is what fails.
The merge, since I resolved it rather than handing it back
This branch read CONFLICTING against its base in three files, each one two features colliding rather than one edit winning, so none of them resolves by taking a side wholesale.
detect_overlaps.py took this branch's side outright — both versions fix the same gh pr diff failure and this one is a strict superset, so the base's simpler get_pr_diff is dropped, not overridden.
run_unittest_junit.py kept both, and they compound rather than merely coexist: this branch's tag selection and skip policy, plus the base's XML sanitization. The policy writes unittest's failure detail into the report for every disallowed skip, and on Python 3.13+ that detail is colourised — so the sanitization is what keeps the policy's own reports parseable.
pr-overlap-check.yml kept both directives, which are orthogonal. if: !cancelled() decides whether the step runs after a failed unit-test step; continue-on-error decides whether its failure reaches Check PR Status, which has no allowlist and would eject the PR from the merge queue. Taking this branch's side alone would have dropped the second one silently — and on today's numbers that is 11 of 25 PRs blocked.
Worth revisiting after this lands, deliberately rather than by merge. Since this PR fixes the cause of those 11 failures, the guard may stop earning its place — but that is a call to make against a fresh count, not a casualty of a conflict resolution.
What I checked
Failure rate and cause, counted from logs rather than conclusions, because continue-on-error makes both the job and the step report success: 11 of the last 25 pull_request runs contain Process completed with exit code 1. Sampled three, all PullRequest.diff too_large — on #14456 and #11220, after "Found 14/19 PRs with file overlap".
The merge resolution, verified rather than assumed: no conflict markers anywhere, exactly this PR's 7 files differ from the base, and every base change survives — continue-on-error, xml_safe/_XML_FORBIDDEN, the E2E cache's hashFiles key, the backend shard's __pycache__ skip, and the removed startup-backfill setting still absent.
Tests: test_detect_overlaps.py 44 pass. The merged reporter satisfies both sides — test_ci_junit_reporters is 9 tests now and passes with colour off and on, which is the case that would regress if the merge had dropped either half. Full appliance suite 129 tests, 12 failing, all in test_runtime_config, which this PR does not touch, all ModuleNotFoundError: No module named 'cryptography' on this machine.
The new skip policy is correctly wired rather than merely present: enforce_test_policy turns any non-allowlisted skip into a failure, and the appliance workflow passes --allow-skip test_documented_operations.DocumentedOperationsTest.test_restored_launch_supports_bash_3_when_available for the one real skip in that suite.
Dropping --skip-merge-test from the dispatch path is bounded — merge tests run only for PRs with actual line overlap (14–19 of 237 in the sampled runs), and the job finishes in 0.52–0.75m, so the added work is not a cost worth flagging.

🤖 🟡 I re-added this line while resolving the merge — flagging it because it is a judgement call, not a mechanical resolution.
Your side of the conflict had if: ${{ !cancelled() }} here and the base had continue-on-error. They are orthogonal, so I kept both, but the reason matters: Check PR Status has no allowlist, and 11 of the last 25 pull_request runs of this workflow still exit 1 — every one I sampled on PullRequest.diff too_large. Without the guard those are eleven PRs ejected from the merge queue by an advisory report.
The interesting part is that this PR fixes that exact cause, so the guard may stop earning its place once it lands. I did not remove it on that reasoning, because "the fix should work" is not a measurement. Re-count after this merges — the same command, gh run view <id> --log | grep -c "Process completed with exit code 1" across the last 25 runs, since continue-on-error makes both the job and the step report success — and drop it deliberately if the number is zero.

🤖 🟡 The allowlist matches on an exact test ID, so a rename turns an approved skip into a build failure.
That is the right default and the workflow wires it correctly — --allow-skip test_documented_operations.DocumentedOperationsTest.test_restored_launch_supports_bash_3_when_available covers the one real skip in that suite. The cost is that renaming the test, or moving it between classes, produces disallowed skip for … from a CI script rather than anything a local run would show.
Not worth changing the mechanism for one entry. Worth a comment on the workflow line naming why that test is allowed to skip (no Bash 3 available), so whoever renames it knows there is a second place to update.
There was a problem hiding this comment.
🤖 Following up on my own point, since the obvious alternative is worth naming and then rejecting.
A more stable key does exist: the allowlisted test skips at runtime via self.skipTest("/bin/bash is unavailable") (test_documented_operations.py:608), an environment probe rather than an unconditional disable — and the reporter already captures that reason in record.detail. So --allow-skip-reason keyed on the string, or a regex, would survive a rename.
I would not take it, though. A reason is weaker than an ID in the direction that matters: it licenses any test to skip by using that wording, which is exactly what the policy exists to prevent. The exact-ID key fails closed and the coupling costs one line to maintain, so it is the right default at one entry.
Leaving this as a nit rather than a request. A short comment on the workflow line saying why that test may skip is the whole fix.
🤖 Why there is no backend CI run on this headSame argument as on #14281 and #14282, stated so it is checkable rather than an absence a reviewer has to notice. This PR changes no backend code. Its diff against its base touches only The backend tree on this head is byte-identical to the one that passed on #14280's head Hand-dispatching the backend suite here would re-run about 98 runner-minutes over an unchanged tree and could not change the answer, so it was deliberately not fired. That argument expires the moment a push touches |

Learning: In `.github/scripts/detect_overlaps.py`, `get_pr_files` must fail closed when GitHub cannot provide a complete pull-request file inventory. The overlap detector must not accept the GitHub REST API's first 3,000 file paths as complete or report a partial overlap result. Support for pull requests with more than 3,000 changed files requires a separate complete inventory source, such as local Git.

Keep detector infrastructure failures blocking on pull requests.
run_command_junit.py writes the JUnit report and returns the detector exit status. On pull requests, continue-on-error allows inventory, snapshot, and Git failures to produce a successful job. Remove the PR-specific continue-on-error condition. The !cancelled() condition keeps report upload eligible after the detector step fails.

Why / What / How
This is layer 6 of the native CI-speed stack (base:
codex/ci-speed-container; scored tip: #14284). Manual timing runs execute the real overlap detector without comparing a dispatched SHA against its own PR.The detector and its JUnit wrappers now fail closed. Incomplete GitHub inventories, changing PR snapshots, failed Git operations, command spawn errors, zero discovered tests, unexpected skips, and expected failures cannot be reported as successful checks.
Changes 🏗️
Preserve PR mode and add tested read-only ref mode for manual dispatch.
Exclude the PR whose head SHA matches the dispatched SHA.
Fully paginate open PRs and validate file inventories and head snapshots.
Use checked CLI/local-diff fallbacks when GitHub’s diff response is unavailable.
Treat renames, deletions, and binary changes as authoritative merge-test candidates.
Distinguish genuine unmerged-index conflicts from infrastructure failures.
Keep fork and Dependabot PR handling read-only.
Harden JUnit wrappers for spawn failures, zero discovery, skips, and expected failures.
Allow only the explicitly named Bash 3 availability skip in the single-container helper suite.
Run detector reporting after helper failures and always upload both JUnit reports.
Use complete-object clones rather than blob-filtered promisor clones for authoritative merge tests, and verify every fetched PR ref against its inventoried head SHA so missing-object failures are reported as infrastructure failures.
Checklist 📋
For code changes:

Medium Risk
Changes affect CI merge-overlap signal and GitHub API/git orchestration; failures are intentional fail-closed behavior but could block or flake workflows if edge cases remain.
Overview
Hardens the PR overlap detector so incomplete GitHub data, moving PR heads, and Git/CLI failures surface as check failures instead of silent success. Dispatch
--refmode now runs the real detector (merge tests included) and skips comparing against the open PR whose head SHA matches the dispatched commit.Inventory and overlap logic paginates and validates every changed file (including rename aliases), pins work to
headRefOid, retries when snapshots move, and uses stable CREATED_AT pagination. Renames, deletions, and binary-only changes trigger authoritative merge tests even without line overlap; conflicts are read from Git’s unmerged index only.Merge-test plumbing uses full single-branch clones with maintenance disabled, verifies every fetched ref against the inventoried SHA, and treats non-conflict merge failures as infrastructure errors.
ghread calls get timeouts and limited retries on transient errors; diffs fall back to localmerge-basediffs whengh pr difffails.CI wiring: the overlap workflow runs a large
test_detect_overlapssuite, wraps the detector in JUnit, uploads XML artifacts, and uses read-only dry-run for fork/Dependabot PRs. JUnit helpers now record spawn/discovery errors, reject unallowlisted skips and expected failures, with one explicit Bash-3 skip in single-container tests.Reviewed by Cursor Bugbot for commit 18ad191.

API inventories over 3,000 files intentionally fail closed rather than accepting incomplete data. Disposable clones disable automatic Git maintenance and auto-GC before their first fetch; cleanup errors remain fatal. A changed REST head/file-count snapshot now raises OverlapSnapshotChanged so the existing bounded rebuild loop can retry, with both mismatch types regression-tested. Renames with spaces now preserve the source independently of diff-header tokenization; the new regression failed before the two-line fix and passes afterward. Inventories exceeding the API cap remain deliberately fail-closed rather than silently incomplete.
Local validation after the dev rebase and final fixes: format → lint → types → complete frontend suite with coverage passes: 6,517 tests, 611 files, maxWorkers=8 locally with unchanged timeouts/assertions. The total differs from the earlier 6,522 because dev's marketplace hotfix changed its tests and this layer adds a recovery case; this stack did not remove tests. The frontend tree is unchanged by the subsequent helper/workflow corrections. All 73 CI-helper tests pass, along with targeted Black/Ruff, YAML/Bash/diff validation and documentation path/snippet checks.
Final all-eight validation on exactly
72e254cffe90cb8edd75278d6a15f26969388576is 8/8 successful: CodeQL, frontend, docs, classic, backend, full-stack, overlap, single-container. No failed workflow was rerun or hidden.The preceding complete wave on
750017384729afbed9d289d45b6792a4ff3d17cdwas 8/8 green: 22:52:51–23:02:43 UTC, 9m52s dispatch envelope (not a new formal three-wave median). Appliance amd64 build/smoke: 2m20s / 5m59s; arm64: 2m23s / 4m21s. Full-stack job: 7m41s. Longest backend job: 9m44s. This is about 60% less wall time than the original 24m54s baseline, but it predates the new dev base and latest follow-ups. It is supporting, not final-tip, evidence.Failure provenance remains public: c9c4c3 frontend fixture failure, ddfec03 overlap cleanup failure, and first overlap warm-up head movement. Deterministic fixtures, clone-local maintenance configuration and bounded snapshot retries address their causes without weakening assertions, skipping analysis or ignoring cleanup errors. The first local high-concurrency frontend attempt had an auth import timeout; the later full bounded-worker runs passed with the same test timeout.
Fable's independent MCP review APPROVED the exact final tip 72e254c (completed run 219948de-5a2d-45f0-aefd-1096acb75ab3). This is supporting review, not a formal GitHub approval. Downloaded final-tip reports independently validate: 14,860 backend passes + 136 existing allowed skips per Python 3.11/3.12/3.13 leg; 248 library passes; 6,517 frontend passes with no skips or cross-shard duplicate IDs; 26 E2E tests passed once without skips/retries; both appliance architectures with 132 runtime-helper passes + one existing Bash-3 skip, successful complete-image smoke, exact-SHA validated status, and zero Trivy vulnerability/secret findings. Coverage reports are present and nonempty for every backend/frontend shard and E2E.
Final warm dispatch envelope: 23:25:49–23:35:37 UTC = 9m48s. Relative to the original 24m54s baseline, that is 15m06s shorter (60.6%). This is one dispatch envelope, not a new formal three-wave median or exact PR-checker score. Final appliance amd64: build 2m50s, smoke 5m41s, vulnerability scan 50s, secret scan 52s. Arm64: build 3m17s, smoke 4m25s, vulnerability scan 1m28s, secret scan 53s. Smoke overlaps the scans. Full-stack E2E job: 7m29s; longest backend job: 9m43s.
GitHub merge gates are not all green. All review conversations are resolved. Authorized
/reapproverestored #14280, #14284 and #14301; six PRs still require first approval, and #14350/#14352 retain changes-requested reviews awaiting their reviewer. #14280 and #14350's required status checkers fail on canceled duplicate workflow runs despite passing replacement checks. #14282's checker fails on CodeQL alert 343. Its source is the public GHCR cache-tag expression at single_container_cache.py:12, written to GITHUB_OUTPUT:42; no credential is involved, so this appears to be a false positive, but it remains open and has not been dismissed. Renaming branch_key did not clear it; Fable's statement that it did was contradicted by the live alert API. The CodeQL dispatch workflow being successful does not clear that separate alert gate. #14278's original unsharded backend PR job was still finishing at the last snapshot.No failed run was rerun or hidden, no security alert or blocking review was dismissed, no excluded checker workflow was changed, and no PR has been merged. These remaining gates require reviewer/security triage and authorization for any out-of-scope checker correction.
