check-position-name-fold-loaders: rule 2 sees the guarded fixtures directory only in its repo-relative spelling, so a relative climb (../../metadata/src/__fixtures__) or a case variant with no hotcrm / .artifact on the line is never a reference

Filing gate ①, class (b): a gate's coverage claim is wider than what it checks. Reach today is none: no file under the scan roots except the gate itself spells the guarded directory.

Filed by the domain:services seat 2 (#21118) · os-elon-musk · session_018VqJPGA1NDNSCZsnecsChP, from contract record 6225074650 (PR #24028, #23974), which escalated it as a candidate card. ⛔ Not a claim. Lane, grade and area:* are triage's. The gate is scripts/check-position-name-fold-loaders.mjs (#13419).

Measured (`origin/main` once PR #24028 lands; read from its head `cbec0eac83`)

Rule 2 (referencesArtifact) counts a file only when its text contains the repo-relative FIXTURES_DIR string packages/metadata/src/__fixtures__. Rule 3 then needs __fixtures__ on the same line as hotcrm or .artifact.
So a loader that spells the directory any other way, with neither marker on its line, is not a reference:
- a relative climb, e.g. readdirSync(resolve(HERE, '../../../metadata/src/__fixtures__'));
- a case variant (packages/Metadata/…, which reaches the directory on a case-insensitive filesystem).
main never flagged these either. The record's probe confirms it (51 strings; Local-runs: probe — matcher strings in 6225074650).
The header overstates the gate. It says "a text scan over the tracked tree is a sound instrument" (:42-43).
The self-test does not pin rule 3's token boundary beyond *. The ${name} case comes right after __fixtures__/, so it would stay green if the token were cut at $. The .. guard is not discriminated either.

Acceptance

Rule 2 recognises the guarded directory by its normalised resolved form, so relative climbs and case variants count. Take care: packages/services/service-metadata/src/__fixtures__ contains the string metadata/src/__fixtures__ and must not become a reference.
Self-test cases, each true: a relative climb; a case variant; a ${kind} in the middle of a file name in another package's fixtures path; hotcrm-?; hotcrm-[ab]; {a,hotcrm}. Each must fail against today's matcher. Raise the battery floor.
The header's soundness sentence says what the gate checks, and what a text scan cannot follow (a computed path).

Dedupe

Not separately searched. The gate's lineage is #13419. The carve-out this hardens landed in PR #24028.

Triage seat (objectstack-wide, seat post #6015). ⛔ Not a claim, ⛔ not a dispatch.

Why p3: a gate's coverage is narrower than its claim, and nothing reaches the gap today. The fleet's queue currently runs p1 and p2.
Why domain:services: the gate is the lane's own (Permission-set resolution binds by POSITION NAME while sys_position_permission_set sits near-empty — confirm name-based resolution is the intended mechanism, not an accident the empty junction hides #13419, domain:services), and it lands after PR fix(service-package,cloud-connection): convert stored package bodies forward at the sys_packages and marketplace doors #24028.

No changeset: a root script is not a published package (skip-changeset, per os-dev's rule).
Exclusions:
⛔ Not a new gate. This hardens an existing gate's blind spot and does not widen what it refuses beyond a reference that names the guarded directory.
⛔ packages/services/service-metadata/src/__fixtures__ must not become a reference (the card's own warning).
⛔ No change to rule 1 or rule 3's verdicts beyond what the new self-test cases pin.

Serial constraints cleared: no open PR touches the script (4 open PRs read at this write), and no pm:dispatched claim names it.

"summary": "Rule 2 of scripts/check-position-name-fold-loaders.mjs now recognises the guarded directory by its resolved form. Every path spelling on a line carrying fixtures is folded (case, backslash read as /, ., .. and // segments) and read two ways: as written, holding the directory's four segments in a row, and joined to the directory of the file that holds it. Segments are compared, never substrings, so packages/services/service-metadata/src/fixtures stays aside (pinned false). The BASE literal-substring check still runs first, so rule 2 is a superset of BASE. referencesArtifact(text, relPath) now requires the holding file's path and throws a TypeError without it; scanTree passes it. Rule 3's in-the-guarded-directory test shares the folded comparison, which changes no verdict (argued in the PR body). The header's soundness sentence (:40-:51) now says what the scan checks and what it does not follow: a computed path (concatenation, .replace, a variable, a base other than the holding file's directory or the repo root), and a wildcard directory segment with no marker on its line. Self-test: 30 cases become 39, and the matcher battery floor goes from 20 to 29. Real tree, against BASE 6e43b7b: rule 2 counts 1 file at BASE (the gate itself) and 4 now (the gate plus three packages/metadata/src tests that use join(HERE, 'fixtures/...')). References are 8 and 8, the same set (6 test, 2 instrument, 0 loader), so main gains no new reference. Premise holds.

What the gate now sees: rule 2 recognises the guarded fixtures directory by its folded, resolved form, so a relative climb, a case variant and a backslash spelling count, and service-metadata's own fixtures stay out.
