2. Evidence (load-bearing)

• L0 FILE PASS — shasum -a 256 -c HASH_MANIFEST.txt → 28/28 OK; tree pin packet_tree.sha256 = 6a6137d198e497612661810db749bc273acafb6227f78e44a3dd022d3e6715f7 == sha256(HASH_MANIFEST.txt).
• L1 RECONSTRUCTION PASS — bash RERUN.sh → RERUN_RESULT: PASS (fresh mktemp -d); exit_codes.json byte-stable 21e03bcb… (before==after rerun).
• L2 FAIL-CLOSED PASS — python3 harness/tkt_base_harness.py → 10/10 probes FAIL_CLOSED, 4/4 controls PASS, any_fail_open=false, exit 0. Detector-correctness rule exercised by P10.
• L3 GOVERNANCE CONSISTENCY PASS — object IDs 326..342 collision-free (strictly above reserved ceiling 325); no orphan (addendum); lanes respected; authority firewall policy + harness P6; no-vector policy + harness P8/P9; APPLY_NOW=NO.
• Pack gates — bash commands.sh → OVERALL_RESULT: PASS (G0..G3 all 0).

3. Fresh KB reconstruct

After publication, the pack was fetched back from KB into a clean /tmp dir and re-verified: shasum -a 256 -c HASH_MANIFEST.txt → all OK, tree pin match, bash commands.sh → OVERALL_RESULT: PASS. (Recorded in current-state §"Fresh reconstruct".)

4. Safety reality checks

Check	Result
T1/FIX7 mutated	NO
N-number/N6/N7/N8/P7 mutated	NO
v0.2 convention packet mutated	NO (read-only references only)
Tool-Kiểm-Thử v0.2 promoted	NO
Semantic Text-as-Code / IU / release PASS claimed	NO (guard enforced, P10)
Codex consulted	NO
Owner asked mid-run	NO
Canonical registry/index fold applied	NO (addendum only; T1 active)
NVSZ root designated	NO
Production mutation / REAL_RUN / QT001 / apply / permit / activation / repoint / cutover	NO

5. Remaining blockers

• TKT-BASE-GOV-FOLD-1 — canonical registry/index fold for 326..342 (owner/GPT; blocked while T1 active). Does NOT block base-pack usability.
• V02-PB-NVSZ-1 — designate the real no-vector root (owner/operator). Affects durable raw-evidence retention only; base packages the policy + dry-run.

6. Next step (after T1 safe point)

When T1 confirms it is no longer mutating the shared registry/index and owner/GPT authorizes: apply TKT-BASE-GOV-FOLD-1 (collision re-scan → append 326..342 → bump revs). Optional future: TKT Semantic Extension (L4–L6) once IU inputs exist.
