From dd6282150db2e4fef593a2098052cdc91ff51ce9 Mon Sep 17 00:00:00 2001 From: Nikolas de Hor Date: Fri, 6 Mar 2026 23:05:51 -0300 Subject: [PATCH 1/5] feat(memory): add decision-memory module for cross-session agent learning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Story 9.5 of Epic 9 (Persistent Memory Layer). Implements Phase 2 of the Agent Immortality Protocol (#482) — Persistence layer. Features: - Record decisions with context, rationale, and alternatives - Track outcomes (success/partial/failure) with confidence scoring - Auto-detect categories from description keywords - Find relevant past decisions for context injection (AC7) - Pattern detection across recurring decisions (AC9) - Time-based confidence decay for relevance scoring - Persistence to .aiox/decisions.json 37 unit tests covering all features. --- .aiox-core/core/memory/decision-memory.js | 549 ++++++++++++++++++++++ .aiox-core/install-manifest.yaml | 38 +- tests/core/memory/decision-memory.test.js | 493 +++++++++++++++++++ 3 files changed, 1061 insertions(+), 19 deletions(-) create mode 100644 .aiox-core/core/memory/decision-memory.js create mode 100644 tests/core/memory/decision-memory.test.js diff --git a/.aiox-core/core/memory/decision-memory.js b/.aiox-core/core/memory/decision-memory.js new file mode 100644 index 0000000000..bc6fd3c4a2 --- /dev/null +++ b/.aiox-core/core/memory/decision-memory.js @@ -0,0 +1,549 @@ +#!/usr/bin/env node + +/** + * AIOX Decision Memory + * + * Story: 9.5 - Decision Memory + * Epic: Epic 9 - Persistent Memory Layer + * + * Cross-session decision tracking system.
