JS-033: `bin/lib/subs.js` — submodule rows + recursion (full parity)

Now: DONE

Classify mounted submodules (3-axis dirty), recurse, and emit sub rows. Part of JS-027. Method: Issues.

Input

Context

be status reports a gitlink as mod iff dirty (Edited|Advanced); stale/health axes stay out of mod (SUBS-027 model). C SUBSDirty lives in sniff (a dog) + switches shards; reimplement in JS over the sub's own shard via keeper/dag. Bare be also RELAYS each mounted sub's status (recursion).

Goals

subs.js: enumerate gitlinks (160000 via JS-028 git.tree) + .gitmodules, mount detect (io.stat <wt>/<sub>/.be), read R4 sub tip, classify ADVANCED (sub tip descends pin, via JS-032 ancestry on the sub shard) → mod/ok.
Recurse: relay each mounted sub's bin/status.js output, path-prefixed.
Full parity vs native be status incl. pin advances + submodule recursion.

Constraints

libdog+abc ONLY. .gitmodules parse via libdog SUBSu8sParse (if exposed) else JS. Edited axis may stay inert (matches C until SUBS-027b) — note it.

WIP

Design decisions

Per-sub: open the sub shard via JS-030 keeper, ancestry via JS-032 dag.

TODOs

Repro-first (test/bin/): clean / advanced-past-pin / behind sub + a recursing tree, each vs native be status. Red→green.

Blockers

← JS-032. Inherits the inert-Edited gap from SUBS-027b.

Outcome

(pending)
