Migration 059 shipped DG (pattern separation) + CA3 (pattern
completion); this migration adds CA1 (match/mismatch detector
between entorhinal input and CA3 output) + Subiculum (hippocampal
output bridge to cortex).
Completes the canonical hippocampal trisynaptic circuit:
EC L2 -> DG -> CA3 -> CA1 -> Subiculum -> EC L5/L6 -> cortex
^ ^
added now
Phase 1 is inspection + manual writes; Phase 2 auto-wires.
- Migration 071: 3 tables (CA1 comparisons + state + Subiculum
outputs). State seeded with id=1, EWMA rates at 0.5.
- mcp_tools_hippocampus_ca1: 4 tools (ca1_compare, ca1_status,
subiculum_output, ca1_subiculum_history).
- ca1_compare auto-derives classification from hash-similarity
match_score (>=0.85=match, <=0.15=mismatch, [0.4,0.6]=ambiguous,
else partial). Phase 2 swaps hash similarity for embedding cosine.
- 9 tests; all green.
- Design proposal at docs/proposals/hippocampus_ca1_subiculum.md.
