Checkpoint — RP Return / Minimal Guard Closure (MCP-readable short proof)

Date: 2026-06-03 Macro: REGISTRIES_PIVOT_RETURN_MINIMAL_GUARD_CLOSURE Final status: PARTIAL Execution mode: read-only verification (query_pg, prod directus); cleanup = BLOCKED_EXTERNAL_AUTHORITY Live mutation: NONE (prod byte-identical)

End state

RP_BLOCKED_MINIMAL for RP cleanup, + Path 3 no-mutation resume available for RP/IU work.

Live BLOCK dims (confirmed == prior 3 checkpoints, no drift)

• birth_orphan_critical_active 59 (54 dot_iu_command_catalog + 5 pivot collisions)
• birth_phantom_real 6
• fs_dot_file_no_registry 16
• dot_pivot_update_not_governed 1
• Safety-net 10 objects + v_rp_classification_governance_map all live.

Global vs RP-specific blockers

Only dot_pivot_update_not_governed = 1 (the tool gate) is a genuine RP-cleanup blocker. The 54 iu_cmd orphans, 6 phantoms, and 15 of 16 FS files are non-RP global hygiene. The 3 cleanup targets (PIV-001/016/021) are BORN and governance-attached; the 5 unborn pivots (PIV-101..106) are a separate birth-collision, NOT cleanup targets.

Chosen RP path

• Cleanup (3 composition fixes): register/birth dot-pivot-update — blocked on dot-dot-register credentials. Substitute tool path unavailable (no DOT updates composition_level/species/registry_group on existing rows; confirmed against the 8 live pivot/matrix DOTs).
• RP/IU work: resume now (Path 3, no mutation) on the live classification view.

Scoped guard result

RP-scoped preflight authored paste-ready + reversible; NOT applied (not needed; keeps prod minimal). Verdict given live state = RP_BLOCKED_MINIMAL: tool unborn. Global guard fn_assert_safe_for_dot_action not weakened; no exception added.

dot-pivot-update status

STILL INVALID — STAGED_FILE_ONLY / UNBORN / NOT_VALID_DOT (sha256 3313c057…effc5).

Smallest remaining blocker

One credential: dot-dot-register (registrar). All other BLOCK dims are non-RP.

RP cleanup decision

NO-GO for the 3 fixes (tool-gated). GO for RP/IU resume (Path 3).

Next macro

REGISTRIES_PIVOT_DOT_PIVOT_UPDATE_REGISTER_AND_COMMIT (operator, creds-gated) — or resume IU work on the live view if creds remain absent.
