The _has_hard_locator gate tested only repo+issue / 40-hex sha / file —
the forge locator vocabulary. detector.sh (A1) builds board_file locators
as kind/id/observed_hash + path (+ snapshot_sha/_ts when attested, #940):
zero keys in common, so a class=actionable board_file entry could NEVER
pass and every heartbeat-planning delta dead-lettered (live seqs 63/68,
dragon-lin, 2026-07-30). Latent since #920; the #920 harness pinned the
detector pilot shape as its malformed example, ratifying the gap.
Fix: `path` becomes a hard-locator arm — and ONLY path. It carries the
same one-call re-verify precision as `file` (re-read <path>; upgrades to
git show <snapshot_sha>:<path> when snapshot-attested). Deliberate
NON-arms: observed_hash (content hash, not an address) and bare path-less
snapshot_sha (would widen the gate past the board_file vocabulary —
review-adopted criterion).
Quarantine is a render-time filter (entries never leave pending.jsonl;
dead-letter.jsonl is ledger + alarm-dedup only), so existing UNCONSUMED
dead-letters re-deliver automatically on the first post-upgrade drain.
Consumed-past dead-letters are not requeued.
Tests: Q11 positive control renders the live seq-68 entry VERBATIM as
CLAIM@seq (real detector emission, not a hand-built dict); negative
controls assert address-free and bare path-less snapshot_sha siblings
still quarantine — the snapshot_sha control at all THREE lengths the
detector's attestation validation ^[0-9a-f]{7,64}$ admits (7-char
abbreviation, 40-hex, 64-char sha-256), so it distinguishes "no arm"
from "arm present but length-gated" (review finding E1). Q1/Q6–Q9
fixtures moved off the now-valid path-bearing shape. RED at base:
exactly the 8 Q11 assertions fail; Q1–Q10 pass under both digests.

Adapter emits snapshot sha/ts out-of-band on fd 3 so a changing value never enters the delta-gate hash. Detector validates advisorily (sha regex, epoch sanity before arithmetic, future-skew slack); malformed metadata is dropped loudly and never gates the wake. Digest renders snapshot_sha/snapshot_ts plus a git-show re-verify hint. Adapters that never write fd 3 are byte-identical.
