Ledger revision (c) against #1582–#1591; arc entries for #1549 and #1581

[AdaWorldAPI]

What

Docs and board only. No code changes.

.claude/research/2026-10-recovery/LEDGER-REVISION-2026-10-16c.md maps the ten merges since #1581 onto the open list.

The gather ban (#1590) reorders the list:

• The preimage op (D2) and D-RA-4 are excluded.
• D-ASM needs a re-spec: its existence half and foreign fan-out are bannered.
• N19 (layout) is promoted, because the join is the layout.
• Recorded as open: the ruling has no DECISION entry, and the existing gather code is untouched.

New collision — WIRE-50: bits 50..52 have two encodings in code, in opposite order.

• The pyramid (maturation_ladder.rs, the knowledge doc) runs 7 Astonishment → 0 Wisdom.
• CausalEdge64::with_novelty_wisdom (deepnsm-v2 wire: every CE64 field of a parsed triple from its source, Gadamer gate first; plan D-CGW-0..12 #1591) runs 0 = not on the ladder, then 1 Staunen ..= 7 wisdom.
• D-CGW-1's gate keeps wire edges inside the probe for now.
• Merged with D-MATURATION3-1.

Closed:

• C31: lance-graph doc drift (docs: rev-pin template, TD-POPCNT, AVX2 oracle note; OpenCog oracle and lance-graph-cog decisions #1582).
• C32: OpenCog is an oracle only (docs: rev-pin template, TD-POPCNT, AVX2 oracle note; OpenCog oracle and lance-graph-cog decisions #1582).
• C33: CATS optional fields bind three-valued (sap: optional CATS code fields bind three-valued through validity planes #1588).
• C34: WCOJ pre-work measured (board: co-research map — worst-case-optimal joins (leapfrog family) for D-ASM-11 #1586, WCOJ map items 1–3: cyclic fixture, bag oracle, galloping seek_from, GYO, P-7 check #1587).
• C35: the G1/G2 loci (deepnsm-v2 wire: every CE64 field of a parsed triple from its source, Gadamer gate first; plan D-CGW-0..12 #1591).
• C36: the Gadamer gate runs on parsed data (deepnsm-v2 wire: every CE64 field of a parsed triple from its source, Gadamer gate first; plan D-CGW-0..12 #1591).
• C37: the measured modulo-64 stamp failure, now evidence for O30.
• C38: the arc catch-up (board: catch up merged PRs #1388–#1588 (arc, status, plans, debt, open items) #1589).

Connections:

• K9: the join is the layout.
• K10: one CE64 code table settles WIRE-50, DOC-WIRE (1), D-46 and D-CGW-1/9/10 together.
• K11: D-CGW-4 should call Reaction::verdict.
• K12: failing tests for the two stamp failures.

Board:

• arc entries for research: D-ORACLE-0 original-oracle fidelity and 64 auditable thoughts #1549 and Ledger update deduplicated against #1579; DOC-WIRE (2); N21 verification #1581, which board: catch up merged PRs #1388–#1588 (arc, status, plans, debt, open items) #1589 missed;
• new entry 2026-10-16-ledger-revision-1582-1591.md and its index row;
• LATEST_STATE and AGENT_LOG lines.

Gates

• append_only_gate.py origin/main: OK.
• entries_index.py --check: current (361 rows).
• supersession_index.py: regenerated last, with no change.
