Skills carry the records they cite, and the map records what nothing checks

[OpenCnid]

What changed

Four skills vendor the records they cite as 31 byte-identical mirrors under
<skill>/references/, so a skill directory resolves every citation it makes
with no Trellis repo present.

Skill	Records	Bytes
judge-composition	13	347 KB
complexity-convocation	9	201 KB
loop-orchestrator	5	183 KB
self-play	4	124 KB

The gap was load-bearing, not cosmetic: complexity-convocation cites
JUDGE_COMPOSITION_GAME.md §6 rules by number and deliberately never restates
them, so outside the repo "rule 4", "rule 12" and "rule 20" resolved to
nothing. FOUR_JUDGE_BASIC_MODEL.md supplies the registries and YAML judge
schema the composer draws from.

Each folder's README.md is the manifest — canonical source path, bytes and
SHA-256 per file, taken at 65fdb1f. Provenance sits there rather than in file
headers, because byte-identity to the source is what makes the hashes
verifiable and a header written into the file is the first thing to break it.

No sync check is installed, by decision: these are portability snapshots.
The authority ordering in .claude/skills/README.md decides every divergence —
the record wins and a stale mirror is replaced from source, never edited.

Contract narrowing

The mirrors carry relative links authored for their old home, so
markdownLinks.excludePrefixes gains one prefix per mirror folder. All 173
broken links were confined to those folders and none sat elsewhere, so link
checking stays live on every SKILL.md and skill README.md.

Records updated

density-chain C7 and C13 are densified in the commit that falsifies them
(rule 22). C7 carries the copy layer now sitting under the nine skills' DERIVED
standing; C13 takes the exclusion array as a fresh instance of the
exists-implies-named gap it already names. The HTML render is brought level
in four places.

Nine further branch classes are stale against earlier commits
(11335e7, 5b1d0e5, 65fdb1f) and are deliberately untouched here — rule 22
puts each repair in the commit that falsified it, and rule 12 gives this change
one branch.

.claude/skills/README.md claimed ~/.claude/skills/ holds byte-identical
mirrors; it holds symlinks into this directory. Corrected.

Where this fell short

Both densified sections grew — C7 +233 chars, C13 +338 — after two
compression passes. Densify, never append asks for fixed length; closing the
remainder meant deleting recorded receipts, which is the wrong trade in a
document whose contract reads every number here is as recorded. Flagging it
rather than reporting a budget that was held. DENSITY-CHAIN.md carries no
maxBytes in the root contract, so no ceiling was crossed.

fixtures/doubts_workspace/earth_figure_factbase.md is left unmirrored on
purpose: self-play frames it as illustration kept short-lived, and a copy that
travels is an example that anchors.

Verification

• npm test — 119 files / 1424 tests green
• npm run check:repo-surface — PASS (0 issues); its link arm watched red
  at 173 issues before the exemption and green after
• wiki:check --verify — PASS (751 paths routed, roster agrees three ways,
  render compiles)
• The 31 mirrors re-hashed against source; that check watched red on a planted
  one-byte break and green on restore (19(c))
• Each skill directory copied outside the repo with every citation and local
  link resolving — all 9 self-contained
