Five commits on one branch.

1. 97db650 — literature harvest (docs + board only)

A five-area literature harvest (NARS/term logic, bilattice/FDE, EIG/active inference, Hambly-Lyons signatures, SPD/EWA concentration) adjudicated against the ratified post-#1126..#1132 / OGAR #295..#297 architecture and against shipped code.

• .claude/knowledge/literature-harvest-2026-09-01-post-1132.md — ground-truth table, 45-row census, nine detailed rows, MINT NOW / MACROS / CERTIFICATES / V3 SURVIVES / V4 PRESSURE / DO NOT MINT.
• EPIPHANIES.md entry E-LITERATURE-HARVEST-POST-1132-TWO-PILLAR-CORRECTIONS-1.

MINT NOW is empty. Certificate-grade results: Pillar 5+ (jc/koestenberger.rs) is a lawful use of K-S Thm 1, but sigma_propagation::pillar_5plus_bound is the jc generator's empirical CV curve applied to a congruence orbit, and sigma_tension_u4 divides a squared distance by it (deterministic isometry bound proposed as the expressible replacement, probed). Greedy INFO_GAIN admission has a published Ω(n/log n) lower bound; EC² is the adaptive-submodular repair as a rung-local script. One v4 pressure (a conative pair) survives its witness pair and is blocked on a scope ruling.

2. 7751581 .. 1a3c729 — Pillar 11 green for lattice walks + register audit pins (code)

Hambly-Lyons Theorem 5/6 (Annals of Math 171, 2010): a lattice word of length L is separated from the identity at depth ⌊2e·ln(1+√2)·L⌋ = ⌊4.7916·L⌋ (d=2; × (2⌈log₃(d/2)⌉+3) in general). Version trap, caught by CodeRabbit on this PR and confirmed against the Annals PDF (1a3c729): the arXiv math/0507536v2 preprint states this as Theorem 2 with e; the published proof sets x = 2·log(1+√2)·L. The code and every doc now carry the published constant. New W6 leg in crates/jc/src/hambly_lyons.rs (gated behind hambly-lyons; default build stays zero-dep/DEFERRED):

arm	measured
reduced words of length ≤ 3 at depth ⌊c·L⌋ (LATTICE_L_MAX = 3; the doubled depth makes longer words allocate 2^depth coefficients)	52/52 separated
tree-like words (random c c⁻¹ insertions) at fixed depth 12 (identity holds at every depth)	64/64 at the identity
reduced length-8 words with S^(2) = 1 (the paper's §1.6 figure-of-8 class)	64 found, all separated by depth 3 ≤ ⌊c·8⌋ = 38, 0 unresolved
d = 1 fence: 64 length-6 words on {a, a⁻¹}	exactly 7 signature classes (net increment only)

Disable arm (cap the separation search at depth 2) fails the test. sigker Index regime re-worded as length-parameterized (N ≥ ⌊c(d)·(|X|+|Y|)⌋); depth 2 is a necessary condition only; a single u8:u8 rail read as one axis is out of regime; arbitrary quantized step vectors stay outside Theorem 5 (Theorem 9 gives non-triviality without a depth). EPIPHANIES.md entry E-PILLAR-11-GREEN-FOR-LATTICE-WALKS-LENGTH-PARAMETERIZED-1 carries a dated ⊘ correction block for the constant.

Pre-#1129 signed register audit (source-level, basin_lanes.rs / atoms::I4x32::sext4): the old lane was true two's-complement i4 over the full [−8, 7]; "−3..+3" is prose only (one illustrative pair, git log -S negative); the #1129 failure is dimensional — the transcribed old encoder maps +x + (−x) to bytes identical to SILENT for every x ∈ 1..=7 (only x = 8 escapes via the +8 → +7 clamp). Bit accounting: old 24×4 = 96 bit = 12 B; new 24×(4+4) = 192 bit = 24 B. No jc pillar certifies a projection level it did not test. Added to epistemic_bassin.rs: const width pins (size_of == 24 == 2·CASCADE_UNITS), the_pair_distinguishes_balanced_conflict_from_silence_at_every_magnitude, and the exhaustive associativity / non-cancellativity census; the module caveat "NOT associative" corrected (sum-then-clamp on L₁₆ is an MV-monoid; the clamp costs cancellativity only).

Two wording risks left for the operator, not edited: epistemic_bassin.rs line 18 ("one extra 12-byte register") vs line 61 ("a reading of the SAME physical lane") cannot both size one row; PR_ARC_INVENTORY.md ~1688 summarises probe_tarski_signed_witness as a one-lane signed field although its polarities live in two slots.

Twin: the bit-exact i128 lattice lane in AdaWorldAPI/ndarray#292 carries the same constant and the same pins with integer equality instead of an f64 tolerance.

Verification

• cargo test --manifest-path crates/jc/Cargo.toml --features hambly-lyons --release hambly_lyons → 4/4 (1.9 s), in-tree now that the ndarray sibling is cloned; cargo test -p lance-graph-contract --release --lib epistemic_bassin → 15/15.
• rustfmt on every touched Rust file; SUPERSESSION-INDEX regenerated last (unchanged).

📝 Walkthrough

Walkthrough

The pull request adds finite-depth Hambly–Lyons lattice validation, updates signature-kernel losslessness documentation, strengthens epistemic basin contracts and tests, and records related literature audits and board state.

Changes

Certification and contract updates

Layer / File(s)	Summary
Hambly–Lyons lattice verification crates/jc/src/hambly_lyons.rs	Adds length-dependent theorem bounds, lattice-word enumeration, reduction checks, false-merge detection, one-dimensional boundary checks, pillar integration, and diagnostics.
sigker certification contract crates/sigker/src/codec.rs, crates/sigker/src/lib.rs	Documents truncation depth that grows with walk length, depth-2 limitations, dimensional exclusions, and non-lattice coverage limits.
Epistemic basin contract validation crates/lance-graph-contract/src/epistemic_bassin.rs	Documents signed-net dimensional loss and saturated accumulation semantics. Adds size assertions and exhaustive conflict, associativity, and non-cancellativity tests.
Audit and board records .claude/board/EPIPHANIES.md, .claude/board/LATEST_STATE.md, .claude/knowledge/literature-harvest-2026-09-01-post-1132.md	Records corrected bounds, lattice-certification conditions, accumulation findings, literature classifications, implementation facts, and deferred primitive decisions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to f6798

The lattice-walk certificate currently has inconsistent theorem attribution and depth rounding, which could make its claimed separation bound incorrect; the PR is not merge-ready until the formula and related documentation are aligned or the risk is explicitly accepted.

Poem

A rabbit checks each lattice stride,
With theorem depths and words beside.
Balanced lanes keep conflict clear,
Saturated sums lose what they cannot hear.
Signatures grow with every length,
And careful proofs record their strength.
