From 3401b6f1da68bb57fef5712c6b689ce4a7d76b2d Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 21 Jun 2026 19:12:21 +0000 Subject: [PATCH] =?UTF-8?q?docs(ledger):=20session=20close-out=20arc=20?= =?UTF-8?q?=E2=80=94=20ledger=20#249=E2=80=93#258,=20docs=20audit,=20ordin?= =?UTF-8?q?al-contradiction=20flag?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.

This **contradicts** the retirement banner in this file (arc below) +and in `roadmap.adoc` §Lane 3 ("no new ordinal rung is to be opened here"). +Meanwhile `wiki/Architecture.adoc` ("Track 2 — Ordinal (partial)") and +`wiki/Roadmap.adoc` ("Ordinal track — partial (the active bottleneck)") still +frame the climb as ACTIVE — i.e. they are consistent with the *code* but not +the *decision*. **Do NOT propagate the retirement to the wiki, and do NOT +delete the ordinal artifact, until the owner reconciles** which is +authoritative: the retirement decision, or the continued climb. Both readings +are live; the fix direction depends entirely on that call. (Also landed on +`main` same day, non-ordinal: `4883ae2` `EchoTransaction` closes #174; +`bd43ad4` `EchoSelectiveProjection` closes #176; `9c56d40` +`entropy-blind-parametric`.) + +**Cross-repo docs-completeness audit (read-only, 2026-06-21).** Verdicts after +*verifying* the audit subagents' claims against the actual tree (several were +over-reported): +* *echo-types wiki ≈ current.* Technical/proof docs strong; the only genuine + staleness is the 2 ordinal wiki files above — GATED on the reconciliation + flag, so NOT auto-fixed.
