From f38270ece3924408f6201a7b3ac91472a5214942 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 8 May 2026 21:01:42 +0000 Subject: [PATCH 1/2] feat(cognition): add per-agent cognitive profiles (autistic-brain features) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces an opt-in `cognitive_profile` selector on the `agents` table that retunes — but does not fork — brainctl's W(m) gate, AGM threshold, Bayesian recall priors, entity synthesis, and retrieval rerank against published cognitive-science theories of autistic perception (HIPPEA, hypo-priors, weak central coherence, monotropism, enhanced perceptual functioning). Default behavior is unchanged everywhere: every existing row gets `'neurotypical'` on backfill, and every gate falls back to its pre-052 hardcoded constants when no profile is supplied. Schema (migration 052): agents.cognitive_profile 'neurotypical' (default) | 'autistic' entities.compiled_truth_variants JSON, contradiction-preservation (WCC) entities.contradiction_count entities.special_interest first-class monotropism tag entities.interest_strength affect_log.sensory_load composite, threshold-checked under EPF affect_log.sensory_dimensions per-channel JSON CLI: `brainctl cognition {list|show|set|status}`, `brainctl interest {add|remove|list}`, `brainctl memory search --focus `. MCP: new `mcp_tools_cognitive.py` extension module with six tools mirroring the CLI surface (cognition_list/show/set, interest_add/list, affect_log_sensory). Design doc with full citations: docs/AUTISTIC_BRAIN.md. Tests: tests/test_cognitive_profile.py — 18 unit tests covering profile resolution fallbacks, W(m) weight retuning, Bayesian prior switching, profile invariants (neurotypical matches legacy constants exactly), and migration 052 idempotency on a synthetic schema. https://claude.ai/code/session_01M68iAFKhR9FrGTRuixcwqE --- db/migrations/052_cognitive_profile.sql | 75 ++++ docs/AUTISTIC_BRAIN.md | 258 ++++++++++++++ src/agentmemory/_gates.py | 25 +- src/agentmemory/_impl.py | 118 ++++++- src/agentmemory/cognitive_profile.py | 234 +++++++++++++ src/agentmemory/commands/cognition.py | 382 +++++++++++++++++++++ src/agentmemory/lib/belief_revision.py | 51 ++- src/agentmemory/lib/write_decision.py | 41 ++- src/agentmemory/mcp_server.py | 5 + src/agentmemory/mcp_tools_cognitive.py | 434 ++++++++++++++++++++++++ tests/test_cognitive_profile.py | 358 +++++++++++++++++++ 11 files changed, 1946 insertions(+), 35 deletions(-) create mode 100644 db/migrations/052_cognitive_profile.sql create mode 100644 docs/AUTISTIC_BRAIN.md create mode 100644 src/agentmemory/cognitive_profile.py create mode 100644 src/agentmemory/commands/cognition.py create mode 100644 src/agentmemory/mcp_tools_cognitive.py create mode 100644 tests/test_cognitive_profile.py diff --git a/db/migrations/052_cognitive_profile.sql b/db/migrations/052_cognitive_profile.sql new file mode 100644 index 0000000..7999b61 --- /dev/null +++ b/db/migrations/052_cognitive_profile.sql @@ -0,0 +1,75 @@ +-- 052_cognitive_profile.sql +-- +-- Cognitive profile feature (autistic-brain features).

My PR added three new indexes and seven new columns via migration 052 but left init_schema.sql out of sync, which the parity test caught. Same pattern as migration 051: inline the column ADDs into the original CREATE TABLE statements, append the indexes after the existing 051 block.
