From b8cfab3b68995732b6243aa5f95b0098bdd753ad Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 8 May 2026 08:47:00 +0000 Subject: [PATCH 1/2] =?UTF-8?q?feat:=20Phase=205=20=E2=80=94=20Autonomous?= =?UTF-8?q?=20Knowledge=20Architecture=20(7=20features)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. Epistemic Confidence Model — calibrated uncertainty (established/ provisional/contested/inferred) with evidence counting, auto-promotion via sleep Phase 5.12, and query-time epistemic filtering 2. Explainable Memory Operations — every retrieval returns WHY via ExplanationFactor[] (rank score, epistemic status, search mode, temporal decay). New memforge_explain tool for per-memory state audit 3. Causal Memory Graph — inferred cause→effect chains from temporal patterns via sleep Phase 6.1, recursive CTE traversal, and memforge_predict tool for "what typically follows X?" 4. Hierarchical Abstraction Engine — auto-extract principles from meta-reflections via sleep Phase 5.11, memforge_principles and memforge_mental_models tools 5. Adaptive Sleep Intelligence — per-phase analytics tracking, auto-skip phases with 3 consecutive zero-change cycles 6. Memory Sentiment Tagging — keyword-inferred urgency/sentiment/ session_type context signals on hot and warm tiers 7. Cross-Agent Transfer Learning — memforge_bootstrap copies established knowledge between agents with confidence discounting and provenance tracking Schema: migration-v3.8.sql (epistemic columns, causal_edges, abstractions, sleep_phase_analytics, context_signals) New MCP tools: memforge_certainty, memforge_explain, memforge_causal_chain, memforge_predict, memforge_principles, memforge_mental_models, memforge_bootstrap New REST endpoints: /epistemic, /causal, /predict, /principles, /abstractions, /bootstrap https://claude.ai/code/session_0116EhmLb79eeBTN8P4wwFC1 --- schema/migration-v3.8.sql | 122 +++++++++++ src/app.ts | 197 ++++++++++++++++- src/mcp.ts | 146 ++++++++++++- src/memory-manager.ts | 441 +++++++++++++++++++++++++++++++++++++- src/schemas.ts | 34 +++ src/sleep-cycle.ts | 247 +++++++++++++++++++-- src/types.ts | 109 ++++++++++ 7 files changed, 1268 insertions(+), 28 deletions(-) create mode 100644 schema/migration-v3.8.sql diff --git a/schema/migration-v3.8.sql b/schema/migration-v3.8.sql new file mode 100644 index 0000000..2647cb5 --- /dev/null +++ b/schema/migration-v3.8.sql @@ -0,0 +1,122 @@ +-- MemForge — Migration v3.8: Phase 5 — Autonomous Knowledge Architecture +-- +-- Features: +-- 1.
