16 tests: registry loading (env override, missing registry, unparseable
registry -> None, no crash), detector behavior against a synthetic
registry fixture (independent of the-custodian's live state, so stable
across canon changes) -- rogue ids flagged, all registered kinds incl.
grandfathered legacy patterns (AWQ-/DEC-/OH-/single-digit-task) pass,
template placeholders and .git/history dirs skipped, malformed yaml
doesn't crash the scan, dedup of repeated ids within a repo, no-op when
no registry is reachable.
Full consistency_check + consistency_sweep suite still green (128 tests,
no regressions from the C-31 addition).
