Plan only; no code. This harvests what survives from #1303 (closed unmerged). Ratified v3 by a 5+3 council (ledger in plan §7).

Kept

  • The lexical-address design. A facet's 12 bytes hold six words. Each word is one 16-bit address into an immutable, versioned lexical codebook. Relations are supplied by the driver through the Fisher-z LUT.

  • Two keys:

    • WordId (existing) identifies a surface form.
    • LexicalAddress (new) identifies a (lemma, PoS) reading.
    • readings(WordId) joins them.
  • Three COCA references, re-measured from the CSVs. Only 4 of 4,264 shared words keep the same ordinal, counting ordinal 0. Each reference resolves under its own key:

    • COCA4096 → (word, PoS);
    • 5k → (lemma, PoS);
    • the academic carve → (word, Ambiguous{PoS set}). The carve merged 2,286 rows: 2,283 extra keys plus 3 duplicate rows.
  • The reference lives in the classid's reading mode, which pins (id, version, sha256). It is never stored in the facet bytes.

  • The COCA bake, as two tables:

    • an identity table (lemma, PoS, lemma_evidence);
    • a surface-form table (form, reading, f), where f is the listed-reading share.

    Notes on the bake:

    • f and lemma_evidence are two statements, not a truth pair, and do not reuse TruthU8.
    • Ambiguous academic addresses get lemma_evidence per candidate reading, through the correspondence map. It is never aggregated.
    • Bytes are full range, round_half_even(x × 255). Unknown rows hold fill byte 0.
    • Known/unknown is one bit per table, forced through Option<Prior>.
    • Nothing is counted at runtime.
  • ISS-CE64-EMIT-INVERSE-BIT2-DISAGREE, re-verified. The council also found a second SUPPORTS writer.

Operator escalation — ISS-LXA-ALPHA-FIT (D-LXA-3 blocked)

The ruling says known/unknown uses the alpha split tunnel. The alpha channel is defined as not a bake (no digest, discarded each cycle). Its claim writes only a stamp, its overlay sits only over NodeRows, and its bit means "attended". The options are in plan §3.1:

  • (a) a baked coverage mask shaped like AlphaMask;
  • (b) codebook entries as NodeRows;
  • (c) a new overlay meaning "measured";
  • (d) (a) plus the unchanged overlay as an attention recorder. This is the council's recommendation.

Deliverables

  • D-LXA-1: the newtypes.
  • D-LXA-2: the correspondence TSV generator.
  • D-LXA-3: the bake. Blocked on the escalation and on D-LXC-4.
  • D-LXA-4: the six-slot reading. Gated on its own contract plan; existing Cam96 / SpoFacet readings are unchanged.

Board

  • STATUS_BOARD rows D-LXA-1..4.
  • INTEGRATION_PLANS and ISSUES prepends.
  • The corrected reference entry.
  • AGENT_LOG council record.
  • Entries index and SUPERSESSION-INDEX regenerated.
  • citation-decay --since base: 0 new.

Merge note: #1306 also prepends a 2026-09-30 (1) entry to INTEGRATION_PLANS.md. Whichever PR merges second needs main merged in and that heading renumbered to (2).

Summary by CodeRabbit

  • Documentation
    • Added a proposal for representing lexical readings with reference-specific addresses, including rules for resolving exact, ambiguous, and missing readings.
    • Documented comparisons of three COCA reference sets, including differences in coverage and alignment.
    • Recorded open design questions about coverage masks, attention overlays, and predicate-bit mapping, along with related deliverables and review decisions.
    • No code changes were made.

A word is a 16-bit address into an immutable, versioned COCA codebook; six
words per facet; relations driver-supplied via Fisher-z. Carries the measured
three-reference correspondence (3 of 4,264 ordinals align), the COCA bake with
f/c baked as u8 (no runtime counting), and ISS-CE64-EMIT-INVERSE-BIT2-DISAGREE.
D-LXA-1..4 queued. The #1303 plan files and socket sections are not carried.

📝 Walkthrough

Walkthrough

This change documents differences among three COCA reference sets and proposes versioned lexical addresses tied to a named reference. It records proposed bake and reading deliverables, coverage questions, and a predicate-mask bit-mapping issue.

Changes

Versioned Lexical Address Proposal

Layer / File(s) Summary
COCA reference measurements
.claude/board/entries/2026-09-30-three-reference-sets-are-not-ordinal-aligned.md, .claude/board/entries/README.md, .claude/plans/deepnsm-v2-lexical-address-v1.md, .claude/board/INTEGRATION_PLANS.md
The records compare reference keys, overlap, ordinal alignment, and ambiguity handling. They report 4 matching ordinals among 4,264 shared words and specify reference-scoped ordinals and explicit correspondence.
Address, bake, and reading design
.claude/plans/deepnsm-v2-lexical-address-v1.md, .claude/board/INTEGRATION_PLANS.md
The proposal distinguishes surface-form WordId from reading-based LexicalAddress, defines reference-bound resolution, and specifies offline identity and surface-form tables, quantized priors, and unknown-value handling. It defines four gated deliverables and records unresolved design choices.
Alpha coverage escalation
.claude/plans/deepnsm-v2-lexical-address-v1.md, .claude/board/ISSUES.md
The records describe the conflict between baked coverage status and the alpha attention overlay. They list options, recommend a baked coverage mask with the existing overlay, and state that operator choice is required.
Roadmap and predicate-mask tracking
.claude/board/INTEGRATION_PLANS.md, .claude/board/STATUS_BOARD.md, .claude/board/AGENT_LOG.md, .claude/plans/deepnsm-v2-lexical-address-v1.md, .claude/board/ISSUES.md
The board records proposal status, deliverables, and gates. The council log records review findings, plan revisions, and that no code changed. The issue records state that emission maps bit 2 to SUPPORTS, while inverse mapping interprets it as confounding and returns CONTRADICTS; they request a shared mapping and round-trip test.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Other

Merge Risk: 🔵 Low · up to a3304

The proposal’s index is consistent, but the status board ordering still needs correction. This is a bounded documentation issue rather than a blocker to the proposed design.

…urface form

- Aligned ordinals are 4 of 4,264 (the/there/care/wage), not 3: the earlier
  count dropped ordinal 0. G-REF now requires ordinal 0 to be counted.
- COCA4096 ranks are unique per (word, PoS); a homograph spans several
  ranks, it does not share one.
- The bake splits into an identity table (lemma, PoS, c) and a surface-form
  table (form, reading, f): the reading share is a property of the surface
  form (record -> n 120,048 / v 13,014), not of the lemma row.
Re-measured from the committed CSVs.

… key

- Bake encoding: q = round_half_even(x * 254) in f64, 255 = UNKNOWN
  sentinel; K recorded in the artifact header.
- G-LEX checks each reference against its own key: COCA4096 -> (word, PoS),
  5k -> (lemma, PoS), the academic carve -> (word, Ambiguous{PoS set}),
  since the carve merged 2,286 same-word rows. A PoS-exact academic
  reference is a new version, left open.
- Entry: blank line before the table (MD058).

# Conflicts:
#	.claude/board/entries/README.md
The 255 = UNKNOWN sentinel was a NaN smuggled into an unsigned byte and
was never asked for. f and c now use the full range,
round_half_even(x * 255); a reading without a measured count has no row.

Claude-Session: https://claude.ai/code/session_01DCEP2fZdHYdMCtcEVcTpS2
The baked table is the split tunnel's read-only spine, complete with one
row per reference entry; a measured f/c is an overlay write at the same
address, and "measured" is that row's bit in the AlphaMask. No sentinel,
no holes, no second table.

- Two keys: WordId (surface form, existing) and LexicalAddress (reading,
  new), joined by readings(WordId). WordId is not superseded.
- ReferenceSet gains key_kind; the classid reading mode pins the full
  (id, version, sha256), with a version-mismatch refusal gate.
- c renamed lemma_evidence: (f, lemma_evidence) is not a truth pair and
  does not reuse TruthU8 (floor quantization, 128 sentinel).
- f is the listed-reading share from form_count; fill byte 0 for
  unknown rows; one known mask per table; Option<Prior> accessor.
- §3.1: the alpha channel is defined as not a bake, so "known" cannot be
  an alpha bit as written. Options (a)-(d), recommendation (d). Escalated
  as ISS-LXA-ALPHA-FIT; D-LXA-3 blocked until ruled.
- D-LXA-4 gated on its own contract plan; legacy Cam96/SpoFacet readings
  stay unchanged.
- CodeRabbit: 2,286 = 2,283 extra (word, Pos) keys + 3 duplicate rows;
  INTEGRATION_PLANS names the two tables separately.

- A surface-keyed reference (COCA20K_ACAD) resolves to (word,

A gate both councils run before generating options, and again before
escalating an option set to the operator. It builds a signature per
named concept (what it answers, coordinates, lifetime, persistence,
writer, cardinality; representation recorded but never used for
identity) and runs four tests: same name / same signature, carrier fits
property, no architecture tax, "the premise is wrong" on the menu.
Verdicts: PREMISE-SOUND / PREMISE-SPLIT / PREMISE-WRONG.

Measured instance: the #1307 council asked "which kind of alpha carries
known?" and verified four options; known is a baked property of the
reference set, alpha is same-coordinate runtime state (alpha.rs:7-16),
so the premise itself was wrong.

Wired into 5plus3-council.md (spec freeze + escalation) and
coresearch-council.md (before the scouts + before the map goes out).
