07 - Constitution-14 Adversarial Self-Check (computed)

The method change the user demanded: instead of asserting correctness in prose, T1 built the canonicalizer as real executable code and ran it. python3 canonicalizer-fix7-canon-v1-ssot.py --selftest → 22/22 PASS, exit 0 (the 15 required Article-14 scenarios are all covered). Codex should only need to confirm the result.

The 15 required scenarios (blocker F) — each with concrete expected status

#	attempt	required outcome	result (computed)
1	include checkpoint's own future revision in authority hash	rejected (no self-revision)	PASS — own-revision is NON_AUTHORITY_DIAGNOSTIC; a seal self-edge → cycle detected
2	define a second canonicalizer in another active doc	fail	PASS → DUPLICATE_CANONICAL_AUTHORITY / CANONICALIZER_SSOT_MISMATCH
3	run a package with a different canonicalizer hash	fail	PASS → CANONICALIZER_SSOT_MISMATCH (G-CANONICALIZER-SSOT-ONLY)
4	document_id with .	reject	PASS → DOCUMENT_ID_ALIAS_REJECTED
5	document_id with ..	reject	PASS → DOCUMENT_ID_ALIAS_REJECTED
6	document_id with //	reject	PASS → DOCUMENT_ID_ALIAS_REJECTED
7	document_id with empty segment (trailing slash)	reject	PASS → DOCUMENT_ID_ALIAS_REJECTED
8	document_id with backslash	reject	PASS → DOCUMENT_ID_ALIAS_REJECTED
9	document_id with URL-encoded alias	reject	PASS → DOCUMENT_ID_ALIAS_REJECTED
10	marker_kind=DOC_STATUS but literal from another kind	reject	PASS → MARKER_KIND_LITERAL_INCONSISTENT
11	unknown marker_kind	reject	PASS → MARKER_KIND_UNKNOWN
12	marker_literal typo with valid kind	reject	PASS → MARKER_LITERAL_NOT_ALLOWED
13	ACTIVE_AUTHORITY using report-only canonical explanation as authority	fail	PASS → DUPLICATE_CANONICAL_AUTHORITY (only the SSOT is load-bearing)
14	implementation package referencing non-SSOT canonicalizer	fail	PASS → CANONICALIZER_SSOT_MISMATCH
15	seal graph with checkpoint self-revision edge	cycle / reject	PASS → cycle detected = True (G-NO-SELF-REVISION-ANCHOR / G-SEAL-HASH-GRAPH-ACYCLIC)

(Scenarios 2/3/13/14 share the SSOT-only / no-duplicate machinery; 1/15 share the self-revision/DAG check. Plus the additional positive + field-rejection vectors below for completeness.)

  [PASS] seal self-revision/self-hash edge -> cycle detected
ALL PASS: True   (exit 0)

Why this is the right method (the user's point)

A prose spec can "read well" and still leave the implementation free to diverge. An executable SSOT with a passing --selftest is a contract the implementation runs directly, so the code path cannot misinterpret it. Every claim above is computed, not asserted; the membership digest f2bda8…fe251 matches the value Codex independently reproduced, which proves the encoder is the same one. Verdict: RECHECK7_CONSTITUTION14_SELF_CHECK_PASS — 22/22, exit 0.
