FIX7 / TKT v0.2 Cross-Lane Governance Alignment (2026-06-11)

Host: T1. Authority: NON_AUTHORITY. Codex consulted: NO. T2 v0.2 framework mutated: NO.

Lane boundary (documented, binding for this lane)

concern	owner lane	this macro's action
Tool-Kiem-Thu v0.2 proof-framework conventions	T2	consume, do not modify
FIX7 semantic / N-node / authority-seal	T1	own
v0.2 dev packet / oracle / verifier bytes	T2	read-only; not mutated
v0.2 promotion status	owner/Codex	untouched — remains NON_AUTHORITY / NOT_PROMOTED

T2 conventions consumed by T1 (no parallel framework created)

1. Review-packet structure — README_FOR_OWNER_AND_CODEX.md + runnable tree → adopted verbatim (see packet README).
2. commands.sh / exit_codes.json / HASH_MANIFEST.txt / packet_tree.sha256 — the rec()/run() gate-ledger pattern that records EXP vs ACT and emits exit_codes.json + OVERALL_RESULT → adopted (this packet's commands.sh).
3. Fresh reconstruction — byte-exact rebuild + RERUN.sh step1 manifest verify → adopted.
4. Report-vs-file audit → adopted (see report-vs-file audit doc).
5. No-vector evidence escrow — raw logs local + hash pointer, regenerable by bash commands.sh → adopted.
6. Authority firewall — engineering≠authority, rehearsal≠seal, candidate≠official → adopted (firewall doc, made executable here).
7. Second-pass direct adversarial probes — independent bad inputs outside happy path → adopted (sp_align_probes.py, plus codex_probes.py).
8. Registry/index update discipline — live collision check before allocation → adopted (object-id allocation doc).
9. by-reference byte-identical module pinning (T2 README §3a) — avoid divergent duplicate authority → adopted (encoder + codex_probes pinned by reference, not forked).

T2-framework gaps found

None that block this lane. The v0.2 convention was sufficient and contradiction-free for the FIX7 authority/N-node lane. Therefore status is NOT BLOCKED_BY_T2_FRAMEWORK_GAP.

One non-blocking handoff observation (recorded, NOT patched into v0.2): the T2 packet binds a fixed file-set in HASH_MANIFEST but the convention does not itself prescribe a node-label checker — FIX7 needed an N-node semantic checker that has no v0.2 analogue. This is a FIX7-domain extension, not a v0.2 defect, so it was built in the T1 lane (n_node_checker.py), not added to v0.2. If T2 later wants a generic label-checker convention, this is the handoff note — but no v0.2 change is required for FIX7 to proceed.

Non-mutation attestations

• v0.2 dev packet bytes: read-only, not mutated.
• v0.2 promotion: not promoted (no use of the v0.2 dev oracle as an official seal).
• FIX7/V3 baseline (d9caa9fe…, Packet V3 b95df0a5…, canonicalizer rev3 49c386a9…): read-only, not mutated.
