EW64↔CE64 decisions resolved (5-agent council) + RawEdge/counterfactual shipped (D-ATOM-4)

[AdaWorldAPI]

What

The EW64↔CE64 white-matter seam spec plus the 5-agent dev-council resolution of its three decisions plus the first resolved slice (D-ATOM-4/RawEdge). Builds on the merged hot tier (#446/#447/#448).

Council verdict (R1 architectural / R2 iron-rule / R3 type-accuracy / R4 critic / R5 build-order; orchestrator-adjudicated against full-file source reads)

• ① Plasticity — DROP the "compose Heel.plasticity × MRU" resolution (E-BASIN-NOT-EDGE-PLASTICITY). R4 + source: MailboxSoaView has no Heel column; Heel.plasticity cools via revise_truth (opposite polarity to Hebbian); HighHeelBGZ.edges are CausalEdge64 ≠ EdgeRef — a phantom join. Resolved: coarse strength = the shipped MRU slot-order (EW64 MRU promote — Hebbian hot-tier "stronger immediate edges" (D-EW64-2) #447); per-edge Hebbian = per-plane PlasticityState (gated phase B). No Heel, no new field.
• ② RawEdge — SHIPPED here: wired the orphaned counterfactual module into lib.rs (it wasn't compiled); RawEdge(i8) not u64 (i8 makes mantissa-only structurally unforgeable — size_of==1); impl the existing EpisodicEdge write trait; filled deposit_counterfactual v2 (writes −6 on split). Closes the counterfactual seam — not the prefetch loop (R4's honest reframe). +3 latent scaffold fixes (SplitPoles Eq-with-f32; two v3-stub unused-params).
• ③ Sense-candidate — DEFER (unanimous): firewall-placement design slice, lowest priority.

Tests / clippy

cargo test -p lance-graph-contract --lib → 550 green (+5). Default clippy -D warnings clean.

Process finding

E-READ-NOT-GREP (+ pattern-doc Rule 7): judgment-critical review agents must READ full files, not grep/sed/head/tail — fragments produced four successive wrong plasticity framings. grep locates; reading judges.

Firewall

RawEdge(i8) carries only the inference nibble (opaque); no COCA; zero-dep. The real CausalEdge64 bridge + per-plane plasticity write stay gated (causal-edge offline + the v1/v2 PLAST_SHIFT minefield).

📝 Walkthrough

Walkthrough

Documentation-only PR adding an EW64↔CE64 prefetch-seam specification (Phase A contract, phased roadmap, locked layout, plasticity grounding, and Section 8 resolution) plus AGENT_LOG entries recording grounded encodings, three held @jan decisions, and phase shipping/gating status.

Changes

Episodic Witness Prefetch Specification

Layer / File(s)	Summary
Prefetch seam specification .claude/specs/episodic-witness64-ce64-prefetch.md	Complete EW64↔CE64 prefetch-seam spec: framing, Phase A contract::episodic_edges (EpisodicEdges64 MRU promote/evict, coldest(), contains), DemotionSink seam, phased B–E roadmap and gating, three @jan unblocking decisions, firewall invariants, Section 6 verified locked layout, Section 7 plasticity ground truth (per-basin Heel u8 vs per-plane PlasticityState), and Section 8 resolved-in-principle build order.
Project status and decision tracking .claude/board/AGENT_LOG.md	Prepended AGENT_LOG entries recording the coarse-first → per-plane later build-order resolution, grounding high_heel.rs plasticity as a per-basin u8, documenting three held @jan architectural choices discovered in causal-edge/src/layout.rs, and consolidating HOT TIER shipped/gated phase status with code construction paused pending decisions and a PR+subscribe follow-up.

Poem

I nibble at specs by moonlit code,
A seam of witnesses in tidy mode.
Phase A hops forth while gates softly hum—
Three held questions wait for answers to come. 🐇✨

- Around line 26-32: The fenced diagram block lacks a language tag and triggers
MD040; update the fenced code block that begins with the ASCII diagram (the
GREY/WHITE/COLD block) by adding an explicit language identifier such as "text"
(i.e., change ``` to ```text) so the markdown linter stops flagging MD040 while
preserving the diagram content and spacing.
