main red: REGISTRY source_hash drift after #1072/#1075 reds Registry Verify and Repo self-tests (and skips the lock-gate pin guard)

[hyperpolymath]

What is red

Three standards checks are red on main at 5f82b635, and on every open PR, from one root cause:

• Registry Verify / Registry + topology in sync
• Self Test / Repo self-tests, through two scripts:
  • scripts/tests/build-registry-test.sh: "--check on a clean checkout" fails.
  • scripts/tests/build-scorecards-test.sh: three claimed passes run bash scripts/build-registry.sh --check, which now exits 1. They are component-readiness-grades/M3, estate-constitution/M2 and neurosym-a2ml/M5.

None of the three is a required context, so PRs still merge. But no standards PR can be fully green while this lasts. The self-test step "Lock-gate pin is not stale" runs after the failing test step, so it is skipped on every PR. The guard is therefore not running at all right now.

Cause

#1072 (51eeca7e) and #1075 (5f82b635), merged 2026-09-30, changed files under rhodium-standard-repositories/ without regenerating the registry. Regenerating changes exactly one line:

 home = "rhodium-standard-repositories/"
-source_hash = "sha256:bc9c99e1d48f9b6ca6985fc705976ed0fee560d60c1d3259e1647a382b76a1e1"
+source_hash = "sha256:51b38eb327df7ea430078bd75566d15ab9a6618f19a3b9ee7c2a1cfb8ce6adda"

Why this is not fixed in a drive-by PR

The drifted artefact is .machine_readable/REGISTRY.a2ml. The owner has ruled A2ML dead as a format. So choosing between regenerating it in place and moving the registry off .a2ml is the owner's decision, not an agent's.

Acceptance criteria

• bash scripts/build-registry.sh --check exits 0 on main.
• Registry + topology in sync and Repo self-tests are green on main.
• The step "Lock-gate pin is not stale" runs (not skipped) and passes on the next PR.
• Whichever cure lands, a PR that touches a spec home without regenerating fails its own run. Today it does fail, but merging over it is silent. So this is a merge-discipline item, not a gate change.
