What

A machine-doc-only close-out arc appended to CLAUDE.md (the project ledger). No proof change; All.agda / Smoke.agda untouched. Based on current main (9c56d40), so the diff is just the ledger arc.

Why

Three things needed durable recording at session close:

  1. Ledger catch-up. The gap-closing proofs that landed this session went in without a ledger arc: #249 EchoReversibilityBridge, #250 EchoResidueCell, #251/#254 EchoSearch (decidable + product), #252 EchoApprox Lipschitz, #257 EchoLLEncoding universal gap, #258 proof-debt variance refresh. Now ledgered, with the reused layered opt-in record design lesson.

  2. Cross-repo docs audit (echo-types + 007), claims verified against the tree. echo-types wiki ≈ current; 007 docs more complete than its audit claimed (spec/TYPE-SYSTEM-SPEC.adoc already carries a full §11b Layer 10 incl. set + residue cells; set_stmt is in grammar.ebnf:157). One genuine 007 gap (no docs/README.md index) — a convention call, not filed (007 runs a 0-issue policy).

  3. ⚠ One unresolved owner decision, flagged not fixed. main carries ordinal BH climb rungs 7 & 8 (f89a3aa, a096764) dated 2026-06-21 — the same day as the D-2026-06-21 ordinal retirement. The retirement banner (this file + roadmap.adoc §Lane 3) and the still-active framing in wiki/Architecture.adoc / wiki/Roadmap.adoc now contradict each other. The wiki is deliberately left un-fixed until the owner reconciles which is authoritative — the fix direction depends entirely on that call.

Disposition

Both repos are clean / verified / push-nothing-else. Trust boundary re-confirmed: exactly 3 quarantined postulates, all outside the wired cone. Branch-cleanup list for the owner is recorded in the arc (delete blocked by HTTP 403 + no MCP delete endpoint).

…rdinal-contradiction flag

Catches the machine ledger up to the gap-closing proofs that landed
without an arc (#249 EchoReversibilityBridge, #250 EchoResidueCell,
#251/#254 EchoSearch decidable+product, #252 EchoApprox Lipschitz,
#257 EchoLLEncoding universal gap, #258 proof-debt variance refresh),
records the cross-repo (echo-types + 007) docs-completeness audit, and
flags one unresolved owner decision: main carries ordinal BH climb
rungs 7 & 8 (f89a3aa, a096764) dated 2026-06-21 — the same day as the
D-2026-06-21 retirement — contradicting the retirement banner. The two
ordinal wiki files are deliberately left un-fixed pending that
reconciliation. Disposition: both repos clean/verified, push-nothing-else.
