08 — Live-PG Compatibility Check (Branch H)

Verifies the hardened model against the live substrate (read-only, role context_pack_readonly, db directus, 2026-06-01). Output = the exact substrate blockers (SB-1..SB-9), each with live evidence, the design it blocks, and a non-mutating remediation path. No DDL was rehearsed (read-only inspection only, per mission §12 preference).

8.1 Substrate readiness by component

Component	Live state	Compatible with model?	Note
`governance_registry` (9)	5 active + 4 draft mothers; no GOV-IU; `capability` NULL on actives	Partial	OP-B (no IU owner); capability JSON empty + not in enacted Đ37 (drift).
`governance_relations` (8)	all agency→law; CHECK `{law,agency}`	No (object/axis)	SB-2 — object/axis edges impossible.
`governance_audit_log` (1)	stale 2026-04-24 meta-note, `relation_id=null`	Dormant	SB-7 — Đ37 §5.5 audit loop not closing; activate (reuse), don't replace.
`apr_action_types` (6)	add_field, amend_law, create_item, enact_nrm, patch_ops_code, update_item (* `unimplemented`)	No (governance)	SB-1 — no owner/exception/axis action-types; SB-5 — enact handlers unimplemented.
`apr_request_types` (14)	reclassify/rule_change/schema_*/new_dot/retire reusable; free-text `entity_type` (no CHECK)	Reusable	any object targetable without enum patch.
`approval_requests` / `apr_approvals` (42) / `os_proposal_approvals` (0)	all DOT-repair/birth/reclassify/schema; no sovereign sign-off	No (commit)	SB-6 — COMMIT_FORBIDDEN; enactment = separate human phase (H-1).
`event_type_registry` (40)	`iu.`(16) active; `mother.`(9) governance/proposal active=false (bare names)	No (governance)	SB-4 — no governance/coverage/axis/orphan/anarchy/island/exception event domain; H1 naming.
`system_issues` (~190k)	`template_gap` 182,378 open; orphan `thiếu_quan_hệ`(606)/`thiếu_mã_định_danh`(9); drift(2); `issue_type` free-text (no CHECK)	Partial	reuse orphan+drift types; SB-4 new types must register (Đ45 register-first, not a DB CHECK); anti-spam mandatory at this scale.
`dot_coverage_required` (11)	birth.*/collection/governance.approval/monitoring.dot	No (coverage)	SB-8 — no classification/pivot/governance-coverage/IU/axis coverage row; scanner absent.
`information_unit` (219)	`owner_ref` free-text (not FK); `conformance_status='open'` all	No (IU owner)	OP-B; conformance gate never closes.
`iu_three_axis_envelope` (216)	columns hardcode 3 axes (axis_a/b/c)	No (open-axis)	SB-3 — 4th axis needs DDL.
`dot_iu_command_catalog` (54)	standalone, not in `dot_tools`(309)	No (DOT SSOT)	IU DOT island.
`normative_registry` (47)	Đ37 enacted; Đ20/23/44/45 absent; Đ36/45 drift	Partial	SB-9 / L-2 — law-registration gap + drift.
`law_jurisdiction`	`(law_code, domain, coverage_type, ...)`; classification/pivot agency-orphaned	Partial	object ownership currently only law/domain-grain.

8.2 The substrate blockers (SB-1..SB-9)

SB-1 — Missing governance APR action-types (blocks PROPOSE)

Evidence: apr_action_types = 6; none is assign_governance_owner / grant_governance_exception / delegate_authority / assign_axis_owner.
Blocks: the GAP-PROPOSE step (owner-assign / exception-grant / axis-owner) — PROPOSE returns proposal_blocked (red-team #13/#36).
Remediation (non-mutating design): add 4 apr_action_types rows + handler (assign_governance_owner) / council-review (others). Interim exception home = admin_fallback_log. Decision: C-2.

SB-2 — Object/axis ownership edge un-expressible (blocks APPLY)

Evidence: chk_relations_source_type & chk_relations_target_type both CHECK (… = ANY {law, agency}); 8 live edges all agency→law.
Blocks: writing an agency→object / agency→axis owner edge — APPLY returns apply_blocked: object_edge_unexpressible (red-team #14/#45).
Remediation: new additive table governance_object_ownership(owner_gov_code, object_type, object_ref, scope, ...) (preferred — no CHECK migration) OR widen the CHECK. Decision: C-1.

SB-3 — IU axis envelope hardcodes 3 axes (blocks true open-axis at IU substrate) — NEW Round 4

Evidence: iu_three_axis_envelope DDL columns = exactly axis_a_*, axis_b_*, axis_c_*; 216 rows; a 4th axis ⇒ ALTER TABLE.
Blocks: honoring "no fixed axis array" for IU; a future IU axis silently requires schema change.
Remediation: Axis Registry = ground truth; generic iu_axis_value(unit_id, axis_code, value, ...) store; envelope demoted to a hot-cache projection. Decision: IU technical design (after OP-B).

SB-4 — No governance event/issue types (blocks detection routing)

Evidence: event_type_registry has no governance/coverage/axis/orphan/anarchy/island/exception domain; mother.governance.*/proposal.* are active=false and bare-named. system_issues.issue_type is free-text (no CHECK), so register-before-emit must be enforced by Đ45, not a DB constraint.
Blocks: emitting coverage/axis/orphan issues+events per Đ45.
Remediation: register new types under a GOV-SIV governance/integrity domain (OQ-H1); reuse thiếu_quan_hệ/sai_lệch_dữ_liệu for orphan/drift; enforce register-before-emit. Decision: OQ-H1.

SB-5 — Law-enact handlers unimplemented (blocks auto-enactment)

Evidence: amend_law & enact_nrm handler_ref='unimplemented' (risk high); live enact-via-APR (id 204–210) all rejected.
Blocks: auto-applying any law clause through APR.
Remediation: none at design time — enactment is council_review + manual/admin-fallback enact (the live corpus bootstrap path). Decision: H-1 (separate human phase).

SB-6 — No sovereign sign-off (COMMIT_FORBIDDEN)

Evidence: os_proposal_approvals = 0; apr_approvals = 42 all S178 DOT-repair; zero approvals on any governance/IU/axis/coverage artifact.
Blocks: any commit/enactment. Remediation: human ratification phase. Decision: H-1.

SB-7 — Governance audit loop dormant

Evidence: governance_audit_log = 1 stale row (relation_id=null, codex meta-note).
Blocks: central audit of governance relation/coverage changes.
Remediation: activate the Đ37 §5.5 audit DOTs (reuse the table + registry_changelog(68k)/event_outbox(180k)); do not replace. Decision: implementation (defer-safe).

SB-8 — No coverage-required rows for the new scanner

Evidence: dot_coverage_required = 11 (birth/collection/governance.approval/monitoring.dot only).
Blocks: the governance-coverage scanner has no declared coverage domain.
Remediation: add dot_coverage_required rows for governance.coverage/classification/pivot/axis/iu (scan/propose/apply/audit). Decision: scanner design (Đ23/Đ35).

SB-9 — Law-registration gap + drift (blocks clean law patch)

Evidence: normative_registry lacks Đ20/23/44/45; Đ36 v4.0/v5.0 ambiguity; Đ45 ban_hanh=false leftover; Đ37 v3.3 text vs live columns; law_catalog(5) stale; governance_docs(12) drifted UI index.
Blocks: a law patch that references these laws.
Remediation: GOV-NRM-SYS registers Đ20/23/44/45 + content-only drift fixes. Decision: L-1 / L-2 (content-only, does not block design patch).

8.3 What the substrate CAN do today (so design isn't over-blocked)

Law/domain-grain ownership works now (agency→law edge + law_jurisdiction + inheritance) → law-mode APPLY is operable.
Reuse-ready spines: system_issues (coalesce_key/occurrence_count for anti-spam), event_outbox(180k)/event_read, registry_changelog(68k), admin_fallback_log(22), vps_deploy_log(18), apr_request_types(free-text entity → any object targetable), dot_tools(309)/paired_dot, the orphan (thiếu_quan_hệ) + drift (sai_lệch_dữ_liệu) issue types.
IU machinery (vector_sync_point/qdrant_registry/sql_link/structure_operation/reconstruct fn) is live and can be bound without being rebuilt.

8.4 Answers to Success-Target Q17, Q18

Q17 (aligns with live substrate) → YES — every clause family checked against live PG; the model deliberately resolves ownership relationally (no per-table gov columns), matching the substrate's actual shape.
Q18 (exact remaining substrate gaps) → YES — SB-1..SB-9, each with live evidence + a non-mutating remediation. The hard apply-blockers are SB-1, SB-2, SB-3 (action-types, object edge, axis envelope); the rest are content-only (SB-9), dormant-reuse (SB-7/SB-8), or human-phase (SB-5/SB-6).
