SEC-KN-4a DONE: freeze review round 3 = pass, freeze cleared for the 4b code build

Third independent review round returned pass: all 5 round-2 findings resolved, C1-C8 all pass, nothing open in an escalating category, and the spec is implementable with zero design decisions left open. The reviewer accepted the section 12.1 ratification as legitimate because it rests on a quoted operator selection whose recorded option matches what R1.5 and R1.4 + gate T4 actually say, with T1-T4 correctly excluded from what it authorizes.

Round-3 MINOR fixed in place: R3 step 2 said 'non-empty string' while R2.1 and the section 6 test row put 'empty after trim' in the re-derive set, so a whitespace-only principal_ref satisfied both and a literal implementation would refuse where the matrix expects apply. R3(2) now reads 'non-empty after trim'.

Freeze status is CLEARED for the SEC-KN-4b code build only. T1 (canister WASM upgrade), T2 (merge/mirror), T3 (gate flip) and T4 (identity restore) remain Tier 3 and unexecuted.

Governance sync (SD-17): ROADMAP + OVERSEER-HANDOVER in this commit. ok review --freeze = pass. No product code yet, no merge, no deploy.
