SEC-SEAM-1a round 3: ratify D1-D4, close BLOCKER N1, record round-3 blocked

Operator ratification obtained and quoted verbatim in freeze 12.1 before any rule was edited: D1=A (stamp type:'session' at all mint sites; absent = legacy_session, propose-OK but self-apply-ineligible), D2=A (media out of scope), D3=start empty (S10 ships dormant), D4=A (classification reuses the apply path's own predicate).

The paste-ready prompt this round was launched with said "fix N1 per D4 option A", but that text was written by the round-2 session itself. Treating it as ratification would have been an authoring session clearing its own escalation - the defect that reverted SEC-KN-4a 12.1. The session stopped and asked instead.

BLOCKER N1 (security) closed per D4=A. S3 rewritten: isSeamSurfaceProposal now calls normalizeCanisterProposalForTaskPrecheck and the sibling per-surface predicates, so a proposal that can trigger a seam apply is seam by construction. New frozen rule S3.0 forbids any hand-written seam field list in built code - two consecutive rounds wrote a parallel key list and both were wrong in the same way. Evasion and fix reproduced by executing the predicates, not only by reading them.

All 18 round-2 findings addressed: new ground truth G27-G31, 14-step refusal precedence S6.1, corrected guard table (N5), four mint sites incl. both refresh paths (N9), four mcp_access sites (N11), S10.4 qualification (N14), N15 resolved as the audit row being stale, N18 fixed with a corrected line number.

Round-3 independent review = blocked, 11 findings (11.2). It confirmed 15/18 round-2 fixes and that N1 is closed by construction, but disproved three claims this round asserted: V1 (security) a machine-credential mint path does exist and is the premise D3 was ratified on; V2 a fifth learner-session mint site; V3 "no live behavior change" disproved by execution. Loop halted per the skill's security/blocked hard stops. New operator decision D5 recorded (are Flow / Flow-capture seam surfaces?).

Mechanical ok review --freeze = pass, 0 findings; the auto-written review_stamp was removed by hand, since the semantic verdict is blocked.

SEC-SEAM-1b not started. T1-T5 unexecuted. No merge.
