STATUS-007: a declared sub with a live gitlink but no anchor buckets as ok — an unmounted sub is invisible

Input

Context

Found 2026-07-14 on journal/be: jab status printed 91 ok and no status test hunk while be/test had lost its .be anchor (SUBS-053). A whole submodule had silently dropped out of the status view and the summary still read all-clean.

• views/status/status.js:308-322 — const mounted = isMount(repo.wt, gl.path); an unmounted gitlink takes the else and lands in res.counts.ok++, indistinguishable from a clean file.
• views/status/status.js:432 — the recursion gate if (!s || !s.mounted) continue; drops the sub's own hunk, so nothing else hints at the loss.
• Net effect: a declared sub whose mount is gone reads EXACTLY like a healthy one — jab status test even answers 1 ok.
• A sub declared in .gitmodules WITH a live 160000 gitlink but NO anchor is a broken tree state, not an ok one.
• Confirmed end-to-end: deleting only test/.be in a clean clone reproduces the exact symptom (91 ok, no sub hunk); restoring the anchor brings the hunk back.
• The isMount gate itself is correct (SUBS-049 shape, status.js:480-488) — the bug is the BUCKET an unmounted sub falls into, not the detection.
• Native parity: check what C be status reports for a declared-but-unmounted sub before picking the verb.

Goals

• A declared sub with a live gitlink and no anchor emits a LOUD row (e.g. a mis-class verb), never a silent ok tally.
• The summary line reflects the broken sub so a bare jab status can't read all-clean over a lost mount.
• A clean unmounted-by-design case (if any exists) stays distinguishable from a LOST mount.

Constraints

• Repro test first (work); fix in beagle-ext (JS), no C changes.
• Do not change the isMount detection shape (SUBS-049).
• Keep status byte-parity with native for every case that is NOT a broken sub; confirm the native verb first.
• Minimal diff; no edits to unrelated tests.

WIP

Design decisions

• Sketch: in the else at status.js:310-311, split "declared + gitlink + no anchor" out of the ok bucket into its own row + counter; keep the recursion skip (there is no shard to recurse into).
• Verb choice is open — mis reads naturally (the mount is missing) but must be checked against native be status and the todo bucket table first.

TODOs

• check native C be status output for a declared-but-unmounted sub (parity target)
• repro test: clone with a sub, rm the sub's .be, assert status does NOT report all-ok
• fix: bucket the anchor-less declared sub into a loud row + counter
• verify: a healthy sub still tallies exactly as before (byte-parity)
