Docs-only ⇒skip-changesetis the correct declaration for this repository. - The fix, read in the diff: the §0 "several majors late" paragraph now examples
--from 16, states the floor ("16 today") in the same breath and gives the below-floor remedy; "no penalty for lateness" dropped as a restatement. Premises re-read onorigin/mainef1fcb26a2:MIGRATION_SUPPORT_FLOOR = 16(packages/spec/src/migrations/registry.ts:79), the chain's refusal atchain.ts:177-178,unsupported_from_majoratmeta.ts:975, the failure-mode row atSKILL.md:472. All hold. - Token ratchet paid in content: two clauses deleted, both surviving beside their deletion sites (the

node scripts/pm/check-governed-merges.mjs --pr 22145classifies the single path as Tier H (its output is quoted in the maintainer brief's seat-opinion section as read at posting time). Not flipped ready, not armed.
Deviations noted, none blocking:
- The PR body says "Nothing else in the file states a
--frombelow 16"; its control wasgrep -- '--from 10'only.SKILL.md:93does state--from 15, as the lower bound derived from a range example. Judged in the contract review (item 8): a range-arithmetic illustration, not this defect's class, and the reworded paragraph two lines below now covers the below-floor case; left untouched, put to the maintainer as an optional same-byte swap, not ordered. premise_still_valid: truereported and confirmed by this seat's own re-read onorigin/main.
Acceptance notes (stay notes; no card):
- Neither the skill nor the CLI refusal names the "older route" / "another path" for a below-floor project. The refusal is loud and the remedy's direction is stated; naming the route is a product sentence for the maintainer, raised in the maintainer brief, not filed.
