Shay 4d778c01fc docs(phase4): exit memo + ADR-0020 Phase 5 / Rust parity sequencing (proposed) 
Phase 4 exited 2026-05-16. All three planned lanes shipped:
sample_efficiency (one-shot-per-correction, replay 1.0),
long_context_cost (slope 0.99 linear after ADR-0019 Stage 1),
multi_agent_composition (15/15 public, composition does not
launder identity violations).

PROGRESS.md updated with full Phase 4 narrative and exit
checklist.

ADR-0020 opens the next sequencing decision: Phase 5
(curriculum era) vs. Rust backend parity port. Three options
laid out (A: Phase 5 first, B: Rust first, C: parallel with
per-surface bit-identity gating). Recommendation: Option C.
Status remains Proposed pending user confirmation.

Architecture Decision Records

This directory contains the Architecture Decision Records (ADRs) for the CORE project.

ADRs record significant architectural decisions: what was decided, why, what alternatives were considered, and what consequences follow. They are permanent records — superseded ADRs are archived, not deleted.

Index

ADR Title Status
ADR-0001 Vocab Layer Invariants Accepted
ADR-0002 Ingest Layer Design (original) Archived — superseded by ADR-0012
ADR-0003 Coordinate System Dissolution Accepted
ADR-0004 Rotor as Operator, Not Property Accepted
ADR-0005 Language Pack Contract Accepted
ADR-0006 Field Energy Operator Accepted
ADR-0007 Valence Layer Accepted
ADR-0008 Allocation Physics Accepted

ADR-0012 core_ingest Governance Layer Accepted
ADR-0013 sensorium/ Multimodal Protocol Layer Accepted
ADR-0014 train/ Learning Loop Accepted (Stub)

Session Logs

Session logs record the decisions and rationale from individual working sessions. They are not ADRs — they are the narrative record that informed the ADRs.
