guard(repo_tests): route nine ls-files sites through tracked_paths (#15926) by mrveiss · Pull Request #16057 · mrveiss/AutoBot-AI

mrveiss · 2026-09-08T09:22:43Z

Refs #15926. Does not close it — this is 9 of 42; criteria 2 and 4 stay open.

Single-issue rationale: this is one batch of a 42-site migration against a single issue; there is no second issue to batch with, and splitting it further would put one CI suite behind each call site.

What Changed

Nine guards each ran their own git ls-files "*.py" and re-decided the same three things: the pathspec, whether to scrub the ambient git environment, and how to split stdout. All nine now call tracked_paths, which decides them once.

MAX_DIRECT_INVOCATIONS 42 → 33. Net −56 lines.

Guard	Pathspec
`no_duplicate_dict_keys` · `python_file_size_ratchet` · `bandit_exclude_anchoring` · `credential_vault_resolution` · `enum_union_guard` · `man_page_indexer_path_resolves` · `no_tracked_path_into_worktrees` · `hard_optional_dependency_declared`	`*.py`
`dependabot_requirements_coverage`	`requirements.txt`

Thinking Path

The pathspec at every site is unchanged and each site's Python-side filtering is preserved verbatim, so every guard sweeps an identical population. Two sites filter .worktrees/ in Python and still do; moving such filters into git-side exclude= is #15927 and is deliberately not done here. Keeping the migration to the subprocess call is what makes population equality checkable by inspection rather than by argument.

Two sites are strictly more correct than before. no_tracked_path_into_worktrees and hard_optional_dependency_declared split stdout with .split() — whitespace — so a tracked path containing a space became two bogus entries. tracked_paths splits on lines.

Behaviour on a broken enumeration changes deliberately. These sites raised CalledProcessError on git failure and returned [] on empty. They now raise RuntimeError and EmptyEnumeration. Refusing to report an empty enumeration as a clean tree is the helper's purpose.

Two guards deliberately not migrated, as a class rather than an oversight

audio_extension_allowlist_test and env_var_bare_cast_test pass their enumerator to declare(discover=...), and reach_declarations_test.test_no_guard_can_succeed_against_an_empty_tree drives that against an empty tree to prove the floor fires. tracked_paths raises there instead of returning [], so migrating them breaks the test that proves their floors work.

That is the empty-population tension the census file already documents, reached from the other side: there the empty result is the failure, here it is the evidence. Both mechanisms are right, which is why this needs a decision in _reach.py — most likely teaching examined() to treat EmptyEnumeration as the collapse it is already testing for — rather than an allow_empty= flag, which the census comment correctly calls the obvious and wrong fix. Recorded in the ratchet comment; not attempted here.

Verification

Pre-push suite: 172 passed, 1 skipped. That run exercises every migrated guard, and each carries its own floor — _TRACKED_PY_FLOOR, _MIN_FILES_SWEPT = 4_000, scanned > 4000. Those floors passing is the population check: a migration that changed what a guard enumerates fails them.
The ratchet caught my own line reduction. enum_union_guard_test.py fell 805 → 801 and the push was blocked until both recorded ceilings were lowered, in scripts/python_file_size_known_large.py and repo_tests/python_file_size_ratchet_baseline.py. Both now read 801, matching wc -l.
Migration applied under assertion, not by pattern. Each of the nine edits asserted its target text matched exactly once before rewriting; an edit that silently found nothing would have failed the run rather than passing as a no-op.
Delta measured, not assumed: quoted "ls-files" argv occurrences in repo_tests/*.py went 53 → 44, exactly the nine claimed.
Every repo_tests/*.py parses clean.

Review — first human pass, at `deb70c60be`

Population equality is the load-bearing claim here and it holds. Two smaller
things, and one piece of coordination the PR could not have known.

Both reds are stale — do not act on them

Validate PR template sections   09:36:59 failure   09:56:45 queued
Check same-scope batching        09:40:27 failure   09:56:45 queued

Taken latest-per-name rather than first: each has a newer run queued that
supersedes the failure. I checked the underlying causes too and both are
already satisfied — all four required sections (Thinking Path, What Changed,
Verification, Model Used) have content, Refs #15926 is a valid single
reference, and Single-issue rationale: is present at column zero. The body was
edited after the first runs; nothing here needs fixing.

Worth noting the trap: statusCheckRollup reports the older conclusion while
the newer run sits queued, so the PR page shows red for a PR that is not.

Population equality: verified independently, and it holds

This is the claim the whole migration rests on — "every guard sweeps an
identical population" — so I checked it rather than reading the argument.

No exclude= is introduced at any of the nine sites. Every call is
tracked_paths(ROOT, "*.py") or tracked_paths(root, "*requirements*.txt"),
so git-side pathspec filtering is unchanged from the bare enumerations.
Both Python-side .worktrees/ filters are preserved verbatim — the
removed lines are matched by identical re-added ones. Deferring those to
guards(primitive): an exclusion registry — 41 guards hold exemptions nothing can enumerate #15927 rather than folding them into exclude= is what keeps this checkable
by inspection, and the body is right to say so.
Nine tracked_paths( call sites, matching the claimed nine and the
MAX_DIRECT_INVOCATIONS 42 → 33.

tracked_paths itself defaults exclude to () and takes cwd=repo_root with
scrubbed_git_env(), so a site migrating with no exclusions gets exactly the
population its bare git ls-files returned.

One claim overcounts

Two sites are strictly more correct than before.
no_tracked_path_into_worktrees and hard_optional_dependency_declared split
stdout with .split() — whitespace — so a tracked path containing a space
became two bogus entries.

Only one did:

no_tracked_path_into_worktrees_15203_test.py   -    ).stdout.split()          <- bare, genuinely fixed
hard_optional_dependency_declared_test.py      -    ... out.splitlines() ...   <- already correct

Exactly one removed bare .split() in the whole diff. The improvement is real
for the first and the second was never vulnerable. Not a code defect — a claim
someone will later rely on, which is why it is worth correcting rather than
letting stand.

Coordination: the `_reach.py` fix you defer to does not exist yet

The deliberate non-migration of audio_extension_allowlist and
env_var_bare_cast is the right call, and your framing of it as a class is
right: tracked_paths raising EmptyEnumeration and
test_no_guard_can_succeed_against_an_empty_tree needing an empty result as
evidence are both correct, and they collide. Rejecting allow_empty= is also
right for the reason the census comment gives.

What you could not know: I am the author of #16048, which is the only open
PR touching _reach.py, and the coordinating session has ordered it behind
your EmptyEnumeration fix. I checked every open PR and none carries that fix
— including this one. So the ordering currently waits on something unwritten.

That is not an objection to this PR. It means whoever takes the _reach.py
decision should know the queue believes it is already in flight. I have raised
it with the coordinating session; flagging it here so the record on the deferral
is accurate.

Verdict

Approve on substance. The population-equality argument is the right one to make
and it survives independent checking; the reds are stale; the only change I would
ask for is the "two sites" line, and I would not hold the PR for it.

…15928) The previous push failed by one file, and the failure is the argument. One floor serves two populations: `examined()` bounds what `discover` returned (5,601 tracked python files), `completed()` bounds what the guard finished (5,337, with 262 skipped as unreadable or unparseable). The floor has to clear the lower one while the meta-test measures the higher, so a single band of 500 spent 264 of itself on the skip gap before buying any growth headroom. The remainder lasted an hour. Raising it to 800 would have been the fix this change exists to prevent: a number chosen by feel. Splitting it is the fix -- `skips` for what a guard cannot complete, `growth` for what it may grow before a deliberate ratchet. Each is then chosen against one quantity and a reviewer can see which. audio-extension-allowlist declares skips=300, measured from the hook's own `completed 5337` against 5,599. env-var-bare-cast declares skips=200 and says in the comment that it is a guess, because that guard's `completed` count has never failed and the gap is unknown -- recorded as unmeasured rather than presented as measured. The failure message now names both numbers and says which to raise, since the whole defect was one number silently doing two jobs. `examined()` is deliberately untouched: #16057 documents an EmptyEnumeration collision in that function and the fix belongs to whoever takes it.

…acked

…6048) * chore: claim worktree for #15928 * guard(reach): pin every declared floor to its population (#15928) A floor far below what its own discovery returns fires only against total collapse, and total collapse is not the failure that happens. Partial loss is: a narrowed glob, a moved directory, a change propagated to some call sites and not others. Every floor examined in review during #15896, #15901 and #15913 fired correctly against an empty tree while tolerating the loss of most of a real one. Adoption did not fix this. Both guards that had already adopted _reach declared a number chosen by feel -- 1000 against 5,599 files and 500 against 3,152, 18% and 16% of their own populations. The mechanism was never the missing part. Adds Reach.growth and a meta-test asserting the live population sits within [floor, floor + growth]. growth=0 -- equality -- is the default because a floor at its population turns shrinkage into a deliberate line in a diff. A population ordinary work grows states a band instead, where a reviewer sees it, rather than being pinned low and quietly meaning nothing. Validated in the meta-test rather than in declare(): declaring would walk the tree once per imported guard, and the meta-test already enumerates every declaration, so the guarantee is the same and the cost is paid once. Both existing floors ratcheted to a band of 250, which absorbs ordinary churn in both directions while staying far below the size of any subtree whose loss the floor exists to catch. * guard(reach): pin the floor to the population that binds, not the one discovered (#15928) The pre-push hook rejected the first version and the rejection is the finding: one floor serves two populations. `examined()` bounds what `discover` returned -- 5,599 tracked python files -- while `completed()` bounds what the guard actually finished, 5,337, because 262 are skipped as unreadable or unparseable. A floor pinned to the discovered count clears the first check and fails the second. So the meta-test added here is necessary and not sufficient: it can only see the higher population, and `completed()` remains the binding constraint. Both declarations carry a band of 500 rather than the 250 ordinary churn alone would need, precisely to absorb that gap. Separating the two floors is the fuller fix and is deliberately not this change. Stating the limitation in the test rather than leaving it for the next author to rediscover by the same hook failure. * guard(reach): give the skip gap its own name instead of a wider band (#15928) The previous push failed by one file, and the failure is the argument. One floor serves two populations: `examined()` bounds what `discover` returned (5,601 tracked python files), `completed()` bounds what the guard finished (5,337, with 262 skipped as unreadable or unparseable). The floor has to clear the lower one while the meta-test measures the higher, so a single band of 500 spent 264 of itself on the skip gap before buying any growth headroom. The remainder lasted an hour. Raising it to 800 would have been the fix this change exists to prevent: a number chosen by feel. Splitting it is the fix -- `skips` for what a guard cannot complete, `growth` for what it may grow before a deliberate ratchet. Each is then chosen against one quantity and a reviewer can see which. audio-extension-allowlist declares skips=300, measured from the hook's own `completed 5337` against 5,599. env-var-bare-cast declares skips=200 and says in the comment that it is a guess, because that guard's `completed` count has never failed and the gap is unknown -- recorded as unmeasured rather than presented as measured. The failure message now names both numbers and says which to raise, since the whole defect was one number silently doing two jobs. `examined()` is deliberately untouched: #16057 documents an EmptyEnumeration collision in that function and the fix belongs to whoever takes it. * guard(reach): measure env-var's skip gap instead of guessing it (#15928) It is 0. That guard discovers 3,152 files and parses 3,152 -- every file it enumerates, it completes -- so the 200 it shipped with was slack buying nothing. Worse than useless: it sat beside audio's measured 300, where it inherited an authority it had not earned. A number chosen by feel, under the name this change added to stop numbers being chosen by feel. Declaring it honestly as a guess was weaker than measuring it, which is the pushback I asked for and got. With no gap the floor can pin near the real population rather than below a phantom one, so MIN_FILES_SCANNED goes 2850 -> 3000: slack 152 against a growth band of 400, and the floor still clears completed by 152. The derivation and the command to repeat it are recorded beside the constant, so the next person re-derives rather than re-guesses. If a completed failure ever appears there, that is the moment to raise it -- with the number the failure hands you, which is the mechanism this PR builds.

…efusing (#15897) Two reds, two causes. #15925: line 41 re-derived the root from __file__ instead of calling repo_root(). One spelling exists now; this is one line. The second is a collision between two correct mechanisms. tracked_paths raises EmptyEnumeration rather than returning [], because an empty enumeration reported as a clean tree is the defect it exists to prevent. reach_declarations_test hands every declaration an empty repository on purpose and needs an empty RESULT to compare -- its own docstring asks for 'an empty result to compare instead of an exception that ends the test early and proves nothing'. Caught locally rather than changed in either shared mechanism. Both are right and both stay as they are: 46 has an open analysis on where the general resolution belongs (#16057), and pre-empting it from inside a consumer would decide a question that is not this PR's to decide. Returning [] does not weaken the refusal, it relocates it. REACH's floor of 300 then raises ReachFloorError, which is the typed refusal the meta-test is built around and a stronger signal than the bare assertion it would otherwise accept. An empty tree still fails -- it fails as the mechanism intends rather than one layer above it.

#15897) (#16068) * chore: claim worktree for #15897 * guard(size): count the oversized files the size hook's exclusions hide (#15897) EXCLUDED_PREFIXES removes autobot-infrastructure/ and autobot-backend/code_analysis/ from the size sweep. Both are tracked source, and 47 files in them exceed the 600-line ceiling with no entry in KNOWN_LARGE -- the largest at 2,341 lines, 3.9x the limit. Not because anyone decided they should be exempt, but because the enumeration never offered them to be decided. That is #15897's thesis: the baseline records exemptions, and these are exemptions it was never shown. Counted rather than grandfathered, because adding 47 entries to KNOWN_LARGE would reverse two rulings this change has no standing to overturn: that mapping's docstring says it only ever shrinks and no entry may be added to make a file pass, and EXCLUDED_PREFIXES is mirrored in .pre-commit-config.yaml and pinned by a test, so narrowing it widens the pre-commit hook for every committer -- a scope decision, not a visibility one. A grandfathered ceiling and an unscanned tree are also different claims, and conflating them would lose the difference. So the debt gets its own number, pinned by equality so headroom cannot hide the next one, with the failure message saying which direction moved and what to do about each. Dogfoods #15928: the reach floor is declared through declare() with growth stated separately, and the enumeration goes through tracked_paths (#15926) rather than a thirty-fourth hand-rolled git ls-files. * guard(size): honour the one root spelling, and let the floor do the refusing (#15897) Two reds, two causes. #15925: line 41 re-derived the root from __file__ instead of calling repo_root(). One spelling exists now; this is one line. The second is a collision between two correct mechanisms. tracked_paths raises EmptyEnumeration rather than returning [], because an empty enumeration reported as a clean tree is the defect it exists to prevent. reach_declarations_test hands every declaration an empty repository on purpose and needs an empty RESULT to compare -- its own docstring asks for 'an empty result to compare instead of an exception that ends the test early and proves nothing'.

Returning [] does not weaken the refusal, it relocates it. REACH's floor of 300 then raises ReachFloorError, which is the typed refusal the meta-test is built around and a stronger signal than the bare assertion it would otherwise accept. An empty tree still fails -- it fails as the mechanism intends rather than one layer above it.
