citations: catch reversed ranges, and repair two live sites

The containment test asked only that lo be at or after the section start and hi at or before its end. A REVERSED range satisfies both halves independently, so it cleared. sync.zig carried a range running from 1878 back to 1443 -- digits that cannot both be right -- and it had passed as correct since this checker was written. The test now also requires lo to be at or before hi.

That site is repaired rather than deferred. The digits were unrecoverable but the claim was not: section 8.2 L1517-1520 states it outright, "An accepting clone reply emits zero or more clone cfile cards in RID order ... then clone_seqno NEXT, push SERVERCODE PROJECTCODE, and final comment", with L1504-1505 for iterating from the supplied RID.

6682409ff0 added a section 8.2 range at L1915-1924 for "the store grew". Section 8.2 ends at L1595; L1915 is config-push payload text. The claim is section 3.7(a) L577-578, "file/cfile, including dangling delta, stored content or igot created a phantom" -- which is what artifact_count_grew measures, and the sibling condition on the line above already cites 3.7(b). Left unfixed this failed the ratchet at 174.

Two checker comments asserted things the code does not do: BARE_DEFAULT claimed ambiguity "never manufactures a failure" -- true, while it manufactures roughly 79 silent CLEARANCES -- and the witnesses comment claimed completeness when the loop breaks on first fit. Five draft aliases added so an unrecognised spelling cannot fall through to the all-drafts path unnoticed.

945 citations, 773 correct, 173 broken, 0 unresolvable sections. Baseline holds at 173 while absorbing a new defect and a newly-detectable class.

Sub-manifest: card alphabet, artifact type, and the specification's vectors

Adds S as the twenty-second card letter and SUBMANIFEST as the ninth artifact type, per draft-fossil-submanifests-00 sections 3 and 4. Type determination reassigns after the card scan rather than during it, so no type is committed while cards are still being read (section 9.1). Reading and classification only: no tree walk, no emission.

The draft's seven appendix vectors ship alongside, each named by the SHA3-256 the draft states and checked by a test that recomputes it. check-in: 9b8bad477a user: dmestas tags: sub-manifest
