10 — Remaining Blockers & Owner Decisions

Every remaining BLOCK now has a row/file-level cause and an exact next action.

BLOCK dimension → blocker → owner/action

#	Dimension	Residual	Root cause	Who unblocks	Exact action
1a	birth_orphan_critical_active	54	dot_iu_command_catalog triple-absent; no fitting species, no canonical code, governance role undecided	Owner/taxonomy + Admin	Decide species+role+code strategy (or classify EXEMPT/DEFERRED) → register via dot-dot-register → install trigger → backfill 54 (doc 02)
1b	birth_orphan_critical_active	5	PIV-101/103/104/105/106 codes globally taken by pivot_results; birth_registry unique is on entity_code alone	Owner/DB design	Migrate unique → (entity_code, collection_name) + update trigger ON CONFLICT → re-run backfill (doc 03)
2	birth_phantom_real	6	COL-171/172/173, SPE-NRC/NRM/NRR: entity gone, birth row stranded; no retirement mechanism exists	Owner	Decide retire vs restore (recommend RETIRE — no restore signal); first define a governed retire path (doc 04)
3	fs_dot_file_no_registry	16	15 live operational scripts + dot-pivot-update; only lawful registration path is the credentialed registrar	Admin	Get dot-dot-register creds → register the 15 scripts; handle dot-pivot-update via full path (docs 05, 06)
4	dot_pivot_update_not_governed	1	staged file, unregistered, unborn, ungoverned	Admin + Human L2/L4	Full lawful path: register → birth → governance → health → dry-run (doc 06)
—	governance_gate_ospa	0 (CLOSED)	no ownership seeded	Human L2/L4	Seed OSPA ≥ 1 (doc 07)

Credential / authority inventory

• Present: root ssh, superuser psql (workflow_admin) → enables lawful DB remediation in scope.
• Absent: admin credentials for the governed registrar dot-dot-register (Directus-API); human L2/L4 OSPA approval; owner taxonomy decisions; design sign-off for the constraint migration.

What is explicitly NOT a blocker for the work that was done

The pivot backfill (22 rows) needed none of the above — it used only the proven in-DB birth mapping on a fully-onboarded collection, which is why it was the one lawful mutation applied.
