temporal: no-hindsight replay test + knowledge/board: chess-signature arc (Turk-Polson, intra/inter)

[AdaWorldAPI]

What

Two commits closing the chess-signature arc on the lance-graph side.

1. 505b989e — temporal.rs no-hindsight streamed-replay test. Demonstrates that temporal.rs structurally disables hindsight: a QueryReference::at(v, Strict) present-reader over a game streamed as a version series classifies every future ply Anachronistic and refuses it (via deinterlace projecting exactly 0..=v), while a Retro reader at the same reference sees the future as Spoiler and admits it. Corrects a framing subtlety — Spoiler is reserved for a Retro reader's deliberate peek; a Strict reader's forbidden-future is Anachronistic. 16/16 tests green. Board: E-TEMPORAL-NO-HINDSIGHT-1.

2. 4e08aa30 — knowledge + board sweep. Records the full chess-signature arc in .claude/knowledge/stockfish-nnue-as-perturbation-cascade.md (§ "Wave 3 (final)") and prepends E-CHESS-SIGNATURE-ARC-1 to EPIPHANIES + an AGENT_LOG entry. Headline findings:

   • We reconstructed Turk & Polson, "Chess Signatures of Play" (arXiv 2606.18544, June 2026) from first principles, and its full mathematical substrate already lives in-tree: sigker (Chen–Lyons signature + kernel), jc/hambly_lyons.rs (the tree-like-equivalence uniqueness certificate the paper's identifiability rests on), temporal.rs (the stream), CLAM/CHAODA (the anomaly layer).
   • Personality is ~98% inter (opponent-driven adaptation), ~2% intra (fixed trait) — the capstone measurement (D-SF-NEEDLE-1). Style surfaces only as a specific named rare event (delayed-gratification sacrifice, 9.70×) that averaging and generic anomaly detection both miss.
   • The signature is the right featurization (mechanism confirmed: signature > aggregate, Lévy-interaction > level); magnitude gap to clean ID is fully attributable to missing ingredients (clock channel, deep-search accuracy, depth). Caveat recorded: use signature_kernel, not the jc-flagged signature_kernel_pde.

The stockfish-rs companion PR carries the eight probe examples (and adds the sigker dev-dep).

Summary by CodeRabbit

• Documentation

  • Added final Wave 3 documentation covering chess-based play signatures, personality analysis, and adaptive behavior.
  • Documented strict no-hindsight evaluation, including how future information is excluded from projections.
  • Added findings on rare strategic patterns, opponent-driven variation, and signature-based analysis.

• Tests

  • Added coverage confirming strict temporal views reject future game data while retrospective views can access it.

📝 Walkthrough

Walkthrough

The PR adds strict-versus-retro temporal gating coverage for streamed known-game rows and documents Wave 3 chess-signature findings, including no-hindsight evaluation, personality probes, variance decomposition, and signature-pipeline results.

Changes

Chess signature arc

Layer / File(s)	Summary
Temporal no-hindsight test crates/lance-graph-planner/src/temporal.rs	Adds coverage confirming that Strict excludes future plies as Anachronistic, while Retro admits them as Spoiler during deinterlacing.
Wave 3 analysis and findings .claude/knowledge/stockfish-nnue-as-perturbation-cascade.md	Documents the no-hindsight protocol, personality and impulsivity probes, adaptive variance results, and signature-kernel mechanism confirmation.
Board and epiphany records .claude/board/AGENT_LOG.md, .claude/board/EPIPHANIES.md	Records the chess-signature arc, temporal gate findings, related pipeline notes, and trap-lure status.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Poem

A rabbit saw future rows barred from sight,
While retro hops them into light.
Chess signatures danced in adaptive style,
And kernels traced each curious mile.
“No hindsight!” thumped my paw—
The arc now documents it all!
