12 - T1-Max Final Verdict

Verdict

FIX7_REFACTOR_BLUEPRINT_MAX_REVIEWED_AND_REVISED_READY_FOR_CODEX_CRITICAL_REVIEW

The final internal Max pass audited the XHigh-revised blueprint against live production and the governing law (not against any prior PASS claim), found 7 real defects (3 P1, 3 P2, 1 P3), directly revised the blueprint docs, and re-verified. No blocker; no hardcode/PG-native FAIL; read path open; no invariant changed.

Why not the other statuses

  • Not FIX7_REFACTOR_BLUEPRINT_MAX_BLOCKED_NEEDS_MORE_T1_WORK: every finding was directly fixable and fixed in-blueprint; none requires a redesign or a Codex decision before the critical review. The two operationalizations that extend the literal design (MB-01 complete-set neutralization, MG-01 re-audit gates) are flagged for Codex confirmation, not blocking the Max verdict - they add safety and change no invariant.
  • Not FIX7_REFACTOR_BLUEPRINT_MAX_FAIL_HARDCODE_OR_PG_NATIVE_GAP: SUPERTRACK I/J PASS - no hardcode (incl. disguised), PG-first/native/driven preserved and strengthened (MB-01 replaces an adjective-list with a catalog-derived set; MC-01/MH-01 make source-text strictly diagnostic with PG-native final authority).
  • Not READ_PATH_BLOCKED: all blueprint docs, the XHigh report, the Codex confirmation, the design index, and live production were readable read-only; the governing law (token-capped) was read in full via a sliced subagent; live evidence (proacl over all 46 fns, trigger counts, view composition, birth-family) was gathered successfully.

Per-supertrack verdicts

track verdict
A source & checkpoint integrity PASS_AFTER_FIX (MA-01)
B legacy-entrypoint completeness PASS_AFTER_FIX (MB-01 P1, MB-02 P3) - live: all 46 fns PUBLIC-executable, 0 trigger vectors
C G-DOT-NOOVERWRITE feasibility & authority PASS_AFTER_FIX (MC-01 P1) - PG-native owner-isolation final authority; DOT-scan fail-closed diagnostic
D rollback reopens-bypass PASS_AFTER_FIX (MD-01 folded) - atomic cutover; pinned-source rollback; no mixed authority
E owner/ACL cutover snapshot PASS_AFTER_FIX (ME-01) - snapshot enumerated across every privilege class
F construction-order implementability PASS_AFTER_FIX - no inferred load-bearing list (S00-captured set)
G package split PASS_AFTER_FIX (MG-01) - re-audit gates before PKG-F/PKG-G (law §4G)
H test / guard PASS_AFTER_FIX (MH-01) - guard-quality rules binding; 30 guards hardened, none added/removed
I/J hardcode / PG-native PASS - strengthened
K cross-layer PASS - boundaries intact
L direct revisions 11 patches across 9 docs + index; cross-impact checked

Required-dimension verdicts

  • Zero-hardcode (incl. disguised): PASS (strengthened by MB-01).
  • PG-first/native/driven: PASS (strengthened by MC-01/MH-01).
  • 27 / 11 / 14 / 7 invariants: PRESERVED (non-regressed by every Max revision).
  • 30 guards: PRESERVED (tightened; none added/removed).
  • Legacy neutralization: PASS - complete captured set, blocked not merely unreachable.
  • Directus read retained / authority removed operator-gated, scoped: PASS.
  • Rollback safe-blocked, no bypass/overwrite re-open: PASS.

The five Max pressure-test items (XHigh hand-off), answered

  1. G-DOT-NOOVERWRITE on PG16 without source-text as authority - resolved (MC-01): final authority is catalog owner-isolation; DOT-body scan is a fail-closed diagnostic (DOTs are not pg_proc).
  2. Legacy-entrypoint set complete - resolved (MB-01): live-verified all 46 fns + apply proc PUBLIC-executable; neutralization now over the complete S00-captured set; 0 trigger vectors; birth-family completed (MB-02).
  3. Rollback can reopen legacy PUBLIC EXECUTE or gateway overwrite - resolved (MD-01): S15 rollback returns to the standing safe-blocked baseline (XHB-02); gateway restored by pinned source, never CREATE OR REPLACE; G-BIRTH-NEUTRAL re-checks; atomic steps prevent mixed authority.
  4. Owner/ACL rollback snapshot concrete before REVOKE - resolved (ME-01): snapshot enumerated (ownership + table/view/function/sequence ACLs + schema nspacl + default privileges); captured, verified, rehearsed before REVOKE.
  5. Construction packages implementable without guessing - resolved (MB-01/F): the one inferred list is now the S00-captured catalog-derived set; S15/S16/S17 reference it; no implementer judgment.

Blocking status (unchanged)

Implementation remains BLOCKED. This was Max review only; next is Codex independent critical review. Stage 2.6B, permit, REAL_RUN, QT001 apply, manifest activation, and owner/ACL cutover all remain blocked. Production was READ-ONLY throughout; no object was created, altered, owned, granted, revoked, or executed. The only writes were the blueprint-doc revisions, this Max report, and the two checkpoints.

Do not claim implementation approval. Next after this PASS: Codex independent critical review of the blueprint.
