13 - T1-XHigh Final Verdict

Verdict

FIX7_REFACTOR_BLUEPRINT_XHIGH_REVIEWED_AND_REVISED_READY_FOR_MAX_REVIEW

The independent XHigh pass audited the blueprint against live production evidence and document consistency (not the blueprint's own PASS claims), found 10 real defects (4 P1, 5 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_XHIGH_BLOCKED_NEEDS_MORE_WORK: every finding was directly fixable and fixed in-blueprint; nothing requires a redesign or a Codex decision before Max review.
  • Not FIX7_REFACTOR_BLUEPRINT_XHIGH_FAIL_HARDCODE_OR_PG_NATIVE_GAP: SUPERTRACK J/K PASS - no hardcode (incl. disguised), PG-first/native/driven preserved; the one J finding (XHJ-01) was a clarity fix, not a hardcode.
  • Not READ_PATH_BLOCKED: all blueprint docs, source approval docs, and live production were readable read-only; live evidence was successfully gathered (proacl, ownership counts).

Per-supertrack verdicts

track verdict
A source integrity PASS_AFTER_FIX (XHI-01, XHI-02)
B refactor-vs-greenfield PASS_AFTER_FIX (XHM-01)
C legacy neutralization / bypass PASS_AFTER_FIX (XHB-01, XHB-02) - live proacl=NULL substantiated
D Directus cutover PASS_AFTER_FIX (XHD-01)
E construction order PASS_AFTER_FIX (XHO-01)
F rollback PASS_AFTER_FIX (XHB-02)
G test / guard PASS_AFTER_FIX (30 guards; 2 under-covered families closed)
H package split PASS_AFTER_FIX (XHD-01)
I hard blocks PASS_AFTER_FIX (XHH-01)
J hardcode PASS (XHJ-01 clarity)
K PG-first/native/driven PASS
L cross-layer PASS_AFTER_FIX (XHL-01)
M direct revisions 10 patches applied, cross-impact checked

Required-dimension verdicts

  • Zero-hardcode (incl. disguised): PASS.
  • PG-first/native/driven: PASS.
  • 27 / 11 / 14 / 7 invariants: PRESERVED (non-regressed by all XHigh revisions).
  • Legacy neutralization: PASS (blocked not merely unreachable; gateway overwrite-protected; rollback shown safe).
  • Directus read retained / authority removed operator-gated: PASS.
  • Rollback safe-blocked: PASS.

What remains for Max review

Max should pressure-test, with the worst-case-implementer lens:

  1. Whether G-DOT-NOOVERWRITE is mechanically checkable on PG16 (DOT bodies are not PG functions - how is a DOT body scanned? confirm the DOT registry/source location and that the guard can read it natively, not by assumption).
  2. Whether the "captured Directus SELECT set" (MX-1) plus the "enumerated legacy control-object set" for the ACL cutover are both fully specified enough that PKG-B/PKG-G cannot guess.
  3. Whether the legacy-entrypoint executability check (G-NOLEGACY ACL clause) enumerates ALL legacy authoritative entrypoints (not just the apply/writer fns sampled here) - completeness of the legacy set.
  4. Whether the H02/H04/H05 total-order + regclass binding is byte-reproducible end-to-end against the runtime-evidence DDL (CP-06 fixtures) without a divergence path.
  5. Whether any P2/P3 fix introduced a new inconsistency (full re-scan of counts and cross-refs).

Blocking status (unchanged)

Implementation remains BLOCKED. This was XHigh review only; next is Max 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 created, altered, owned, granted, revoked, or executed. The only writes were the blueprint-doc revisions, this XHigh report, and the two checkpoints.
