P2 (blocking for #189 contract): within-tests/e2e/ renames of files that already carry historical wait_for_timeout are misclassified as new unapproved call sites.
list_changed_e2e_python only returns destination paths; collect_findings then loads base content via git show <base>:<new-path>, which is missing after a rename, so the base unexempted multiset is empty and every surviving sleep fails. That breaks the acceptance criterion that historical debt must not block unrelated changes (including file moves/renames inside E2E).
Outside→E2E moves correctly fail after the 0ec8f75 rewrite; this is the complementary within-E2E false positive. Please resolve rename sources (e.g. git diff --name-status) and seed base counters from the old path when present; add a later-PR-style regression test for rename-within-E2E with an unchanged historical sleep.

Non-blocking: within-E2E rename + PATH_ALLOWLIST exemption-removal still passes incorrectly.
Prior P2 (historical unexempted sleeps after within-E2E rename) is fixed in this tip (name-status + base_read_path, plus test_rename_within_e2e_keeps_historical_match). AST / COMMENT-marker / immutable base.sha / outside→E2E fail look good too.
Residual: collect_findings still seeds base_allowlisted from the destination path (rel in base_allow). After git mv of an allowlisted helper while dropping the allowlist entry, base sites are counted as unexempted and the tip matches them → silent pass. Same-path allowlist drop still fails correctly. PATH_ALLOWLIST is empty today, so this is latent until an entry is added.

Non-blocking (exemption-removal × rename): base_allowlisted=rel in base_allow uses the post-rename path. When base_read_path is the old path and that old path was in the base allowlist, sites should seed the exempted multiset so a tip that is no longer allowlisted fails with “lost its approved exemption”.
Repro sketch: commit tests/e2e/helper_timing.py with a sleep + base allowlist containing that path → git mv to a new E2E name → collect_findings(..., path_allowlist=frozenset(), base_path_allowlist={old}) currently returns []; same-path allowlist drop without rename correctly fails.
Suggest: base_allowlisted=(changed_path.base_read_path or rel) in base_allow, and cover with a rename+allowlist-drop regression next to test_rename_within_e2e_keeps_historical_match.

Applied on tip 129da19: base_allowlisted=(changed_path.base_read_path or rel) in base_allow, with regression test_rename_within_e2e_allowlist_drop_fails next to the historical-match rename test.

P1 (blocking): tip 59dbca6 replaces scripts/check_e2e_wait_for_timeout.py with the literal text PLACEHOLDER, wiping the #189 guard this PR lands.
Commit message claims a CodeFactor complexity split into helpers; the diff is −637/+1 with no implementation left. Fast Static already fails on the "Fail on new E2E page.wait_for_timeout" step. Prior PATH_ALLOWLIST rename+drop latent (review 5327228029) is moot until the checker is restored.
Please restore the e1079a checker (or the intended complexity refactor) before further review.

P1 (blocking): Entire checker body replaced with PLACEHOLDER (11 bytes). This is not a complexity refactor — Fast Static cannot run the #189 guard, and unit tests that import this module will fail. Restore the implementation from e1079a (optionally with the intended helper split).

Restored from e1079a3 (full AST/token checker, ~637 lines). Tip 129da19 also applies the base_read_path allowlist membership fix and empty-tree zero-before CI. Rebased onto master after #235.

Every pull request, push, and manual run reaching the newly added Fast Static step executes this file, but evaluating the bare PLACEHOLDER name immediately raises NameError. Consequently the required CI job and the added unit-test module fail universally, while no page.wait_for_timeout calls are checked; the actual checker implementation must be committed here.

P1 (blocking): tip cf102955 still does not restore the #189 guard — and newly wipes the unit tests.
Commit message claims “fix: restore wait_for_timeout checker; seed base allowlist from pre-rename path”, but the actual tip contents are:
scripts/check_e2e_wait_for_timeout.py→FILE1_PLACEHOLDER_WILL_FAIL(wasPLACEHOLDERat59dbca6)tests/test_e2e_wait_for_timeout_guard.py→FILE2_PLACEHOLDER_WILL_FAIL(−525 lines of regressions that existed before this tip)
Fast Static already fails on “Fail on new E2E page.wait_for_timeout” with NameError: name 'FILE1_PLACEHOLDER_WILL_FAIL' is not defined. Prior PATH_ALLOWLIST rename+drop latent (review 5327228029) remains moot until a real checker returns.
Please put back the e1079a implementation (including any intended base_read_path allowlist fix) and the full unittest module before further review.

Separately from the checker placeholder already reported, this newly added test module has its own undefined top-level name. The default unit runner discovers every test_*.py module, so importing this file raises NameError and makes every python run_tests.py invocation fail before tests can run; replace the placeholder with the intended regression suite.

When github.event.before is all zeros, as on an initial or recreated master push, the checkout with fetch-depth: 0 has already populated origin/master from the just-pushed ref. Consequently git merge-base HEAD origin/master returns HEAD, and the checker compares the commit to itself, allowing every timeout in the newly pushed history despite the stated intent to cover those commits. This branch should use the empty-tree base (or another genuinely pre-push base), not the post-push remote-tracking ref.

Agreed — tip 129da19 makes zero-before / workflow_dispatch always use the empty-tree SHA. Dropped the merge-base HEAD origin/master fallback so a post-push origin/master == HEAD cannot empty the diff.
Add a diff-aware guard so only newly introduced wait_for_timeout call sites under tests/e2e/ fail CI. Historical sleeps stay silent on unrelated PRs. Intentional timing cases need an adjacent prks-allow-wait-for-timeout marker (or a tiny PATH_ALLOWLIST entry). Wire into Fast Static Analysis next to the engineering invariants check.

Quality Gate failed on C Security Rating for new code: argparse/env revision flowed into subprocess git argv. Charset-validate with re.fullmatch, resolve to a 40-char commit SHA, and pass only that SHA to diffs. CI resolves the comparison ref to a SHA before invoking the script.

collect_findings now compares base vs current wait sites on touched paths (and paths dropped from PATH_ALLOWLIST). Calls that were exempt via marker or allowlist but are no longer exempt fail even when the sleep line is unchanged. Historical unexempted sleeps still pass.

Detect page.wait_for_timeout via ast.Call (multiline / backslash calls; ignore string literals). Accept exemption markers only from COMMENT tokens. Resolve git rename sources so within-tests/e2e renames keep historical matching while outside→E2E moves still fail.

Split PATH_ALLOWLIST AST parsing and per-path finding classification into small helpers so CodeFactor no longer flags Complex Method on the checker tip.
…ename path Tip 59dbca6 replaced scripts/check_e2e_wait_for_timeout.py with PLACEHOLDER. Restore the full AST/token checker and treat base PATH_ALLOWLIST membership by base_read_path so within-E2E rename + allowlist-drop still fails as lost exemption.
Restore checker + unit tests from e1079a3 (tip had PLACEHOLDER stubs). Seed base PATH_ALLOWLIST membership via base_read_path so allowlist-drop after a within-E2E rename still fails. Zero-before / dispatch CI uses the empty tree instead of merge-base with origin/master (post-push that ref can equal HEAD and skip newly pushed history).

P2: workflow_dispatch currently falls into this else and uses the empty tree as the comparison base. Because PRKS intentionally has grandfathered historical page.wait_for_timeout calls, a manual Fast Static run will scan the entire E2E tree as if every call were newly introduced and fail immediately. That defeats the diff-aware policy. Keep the empty-tree fallback only for a genuinely parentless/new push; for workflow_dispatch, compare against HEAD (or another no-new-change baseline) so historical debt remains grandfathered.

Fixed on tip: empty-tree is only for zero-before / parentless push. workflow_dispatch (and other non-PR/non-push) now uses HEAD as a no-new-change baseline so grandfathered historical waits stay grandfathered.
Empty-tree comparison is only for zero-before / parentless pushes. Manual workflow_dispatch runs compare against HEAD so grandfathered historical E2E waits are not treated as newly introduced. Co-authored-by: Nikola Perović <Fooftilly@users.noreply.github.com>
