…16249) `pipeline-scripts/check-pre-commit-hook-pr.sh` is run by two python-suite tests, and no pattern in `.github/filters/python-paths.yml` matched it. A change confined to the wrapper computed `python != 'true'`, the required-context shim reported `python-suite` green, and the tests that exercise the change never ran — a guard bypassable by touching the one file it exists to watch. Six paths, not the one reported: four wrappers with sibling tests (check-pre-commit-hook-pr.sh, check_baseline_no_growth.sh, detect-hardcoded-values.sh, pr-queue-open-list.sh) and the two libraries they source (scripts/lib/git-scope.sh, scripts/lib/hardcoded-value-rules.sh). Both extra findings came from the new guard failing against my own enumeration, before review rather than after: * I paired scripts to tests by NAME, which crosses a hyphen/underscore boundary silently — pr-queue-open-list.sh is tested by pr_queue_open_list_test.py. The guard pairs them by CONTENT and named it. * my source-line pattern matched the quoted argument as `[^"]+`, which stops at the first INNER quote. The portable spelling nests them — `source "$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)/../x.sh"` — so it yielded `$(cd `, ended in no `.sh`, and was dropped as if the line sourced nothing. Only the simple `"${REPO_ROOT}/..."` spelling parsed, which is how hardcoded-value-rules.sh — sourced by two of the four — surfaced at all, and how git-scope.sh then read as absent. The extractor now matches the `.sh` argument itself, last one on the line. Both variables are assigned `$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)`, checked in each script rather than inferred from the name. The transitive closure was checked too, per the issue's "not verified" note: neither library sources anything, though both look like they might — git-scope.sh contains the word `source` four times and hardcoded-value-rules.sh six, and every occurrence is prose in a comment. An anchored grep returned zero for the first; counting the unanchored word is what made that zero trustworthy. Why the existing coverage guard cannot catch this, which the issue did not record. `python_filter_covers_its_guards_test.py` exists for exactly this class and two independent things stop it: it sweeps `repo_tests/` only, and `pipeline-scripts`, `scripts` and `tools` sit in its `_NOT_A_READ` set — whose stated premise, "trees whose contents no guard reads directly", is false, since check-pre-commit-hook-pr_test.py reads its own `.sh`. Sweeping those directories would still discard the finding. Widening it was measured, not guessed. The sweep was reimplemented independently and validated against the recorded baseline (38 uncovered reads, equal to MAX_UNCOVERED_READS and to the 38 recorded entries) before any option was judged: today 38 also sweep pipeline-scripts/ 58 ...and drop pipeline-scripts from _NOT_A_READ 63 ...and drop scripts too 77 Every option raises a count whose own rule is that it may only fall, and the 25 newly surfaced reads are mostly workflow and config files — a different population from this defect. So the narrow invariant is asserted directly in `repo_tests/python_filter_covers_tested_shell_wrappers_test.py`: a wrapper that python-suite tests must itself be able to trigger python-suite. Exact, and it costs the ratchet nothing — re-measured after the filter change, still 38, so the equality rule holds in both directions. That guard imports the matcher from the existing one rather than restating it. Two matchers drifting apart would disagree silently and certify coverage the real gate does not grant; a rename breaks the import loudly instead. Four of its six tests are controls: the sweep must find at least four tested wrappers and name the reported one; the extractor is pinned to exact sourced sets for all four real wrappers, including the empty one, which is what would catch an extractor that started matching prose; an argument that does not resolve to a repository file is REPORTED rather than skipped, so an unreadable source line cannot look like a script that sources nothing; and the imported matcher is asserted to say no to an absent path, without which both findings tests pass vacuously. Closes #16249

Record source lines without a .sh match.
_sourced_paths promises to return every unresolvable source argument, but this branch discards valid extensionless source targets. The coverage checks then ignore that dependency, and test_no_source_line_goes_unread still passes. The repository also uses extensionless sourced files, so .sh is not an enforced source requirement.
Add raw to unresolved before continuing.

`python-suite shard 8/12` failed on `glob_declared_reads_15900_test.py::test_the_record_names_exactly_the_guards_that_declare_each_glob`: declaring-but-not-recorded: ['repo_tests/python_filter_covers_tested_shell_wrappers_test.py'] The guard added by this PR sweeps `pipeline-scripts/*.sh`, and #15900's record names every guard that declares each tracked glob so a sweep cannot quietly appear or vanish. A new declarer has to be added in the same change — which is the record doing its job, not an obstacle. Only `*.sh` needed recording. The guard also calls `glob("*_test.py")`, and that pattern is not tracked: the record carries `*_test.sh` but no `*_test.py`. Checked the two other guards this session added for the same trap — `command_position_scan_test.py` and `hook_declarations_are_reachable_test.py` — and neither globs at all; they read a module's `dir()` and the router's exported routes respectively. So this is the only entry needed.

Thinking Path
pipeline-scripts/check-pre-commit-hook-pr.shis run by two python-suite tests, and no pattern in.github/filters/python-paths.ymlmatched it. A change confined to the wrapper computedpython != 'true', the required-context shim reportedpython-suitegreen, and the tests thatexercise the change never ran — a guard bypassable by touching the one file it exists to watch.
The issue's coordination note said to wait for #16199; that merged 2026-09-13, so the hold is released.
The issue attributes this to one cause and there are two.
python_filter_covers_its_guards_test.pyexists for exactly this class, and the issue notes it sweeps
repo_tests/only. It also carries_NOT_A_READ = {"repo_tests", "pipeline-scripts", "scripts", "tools", "libs", ".git"}, whose statedpremise is "trees whose contents no guard reads directly". That premise is false —
check-pre-commit-hook-pr_test.pyreads its own.sh— so even sweepingpipeline-scripts/woulddiscard the finding. The guard structurally cannot see this.
What Changed
Six paths added to the filter, not the one reported: four wrappers with sibling tests
(
check-pre-commit-hook-pr.sh,check_baseline_no_growth.sh,detect-hardcoded-values.sh,pr-queue-open-list.sh) and the two libraries they source (scripts/lib/git-scope.sh,scripts/lib/hardcoded-value-rules.sh).repo_tests/python_filter_covers_tested_shell_wrappers_test.py— six tests asserting the narrowinvariant directly: a wrapper that python-suite tests must itself be able to trigger python-suite.
Verification
Widening the existing guard was measured, not argued. I reimplemented its sweep independently and
validated it against the recorded baseline — 38 uncovered reads, equal to
MAX_UNCOVERED_READSandto the 38 entries in
UNCOVERED_READS— before judging any option:pipeline-scripts/pipeline-scriptsfrom_NOT_A_READscriptstooEvery option raises a count whose own rule is that it may only fall, and the 25 newly surfaced reads
are mostly workflow and config files — a different population from this defect. Hence the narrow
guard. Re-measured after the filter change: still 38, so the equality rule holds in both
directions. Adding patterns could have lowered it, which fails the same assertion.
Two of the six paths came from the new guard failing against my own enumeration — before review,
not after.
pr-queue-open-list.shis tested bypr_queue_open_list_test.py. The guard pairs them bycontent and named the one I had missed.
[^"]+, which stops at the first innerquote. The portable spelling nests them —
source "$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)/../x.sh"—so it yielded
$(cd, ended in no.sh, and was dropped as if the line sourced nothing. Onlythe simple
"${REPO_ROOT}/..."spelling parsed. That is howhardcoded-value-rules.shsurfacedat all, and how
git-scope.shthen read as absent.The second is the one worth dwelling on: a parser that fails closed on an unparseable dependency
reports "sources nothing", which is indistinguishable from a script that genuinely sources nothing.
The extractor now matches the
.shargument itself, and returns what it cannot resolve instead ofskipping it —
test_no_source_line_goes_unreadfails on any argument that does not land on arepository file.
Transitive closure checked, not assumed, per the issue's own "not verified" note. Neither library
sources anything — and both look like they might:
git-scope.shcontains the wordsourcefourtimes,
hardcoded-value-rules.shsix, every occurrence prose in a comment. An anchored grep returnedzero for the first; counting the unanchored word is what made that zero trustworthy.
Four of six tests are controls: the sweep must find ≥4 tested wrappers and name the reported one;
the extractor is pinned to exact sourced sets for all four real wrappers, including the empty one,
which is what would catch an extractor that started matching prose; unresolvable arguments are
reported; and the imported matcher is asserted to say no to an absent path, without which both
findings tests pass vacuously.
The guard imports
_filter_patternsand_is_coveredfrom the existing one rather thanrestating them. Two matchers drifting apart would disagree silently and certify coverage the real
gate does not grant; a rename breaks the import loudly instead.

Not in this PR
AC2 asked for a decision on extending
python_filter_covers_its_guards_test.py, and the decisionis no — with the numbers above as the reason. Extending it cannot be done without raising a
shrink-only count, and the population it would surface is not this defect. If the owner would rather
widen it and re-baseline, that is a deliberate ratchet decision and the measurements are here to
support it.
_NOT_A_READ's false premise is left in place. Correcting it is the same re-baselining decision,and doing it inside a fix for one filter gap would bury it. Recorded on the issue.
Closes #16249
Single-issue rationale
#16249 is one filter file plus the guard that keeps it honest. It cannot ride with another issue
because the guard it adds asserts a property of
.github/filters/python-paths.ymlitself — a secondissue's changes in the same PR would make a failure there ambiguous between the two.
The natural batching partner would be #16248, the other coverage-guard gap I measured today. It is
deliberately not ridden with: that one needs a 315-route baseline decision, which is a ratchet call
at a different risk level entirely, and I posted measurements there rather than code.
