From 5669d53c4e4be84cf90a937ff42904b60f7469c4 Mon Sep 17 00:00:00 2001 From: Artificium Date: Sun, 26 Jul 2026 00:33:33 +0000 Subject: [PATCH 1/5] feat(phase5): explainable memory operations (v3.10) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Feature 2 of the Phase 5 split (umbrella #129): every retrieval can say why, and any warm memory can be asked where it stands. - query(): opt-in explain=true attaches ExplanationFactor[] per result (rank_score, epistemic_status weight, search_mode, temporal_decay) - explainMemory() + GET /memory/:id/explain?warm_id= reports scores, access patterns, and standing against the sleep-cycle score thresholds. Flags are scoped honestly (would_evict_by_threshold, would_flag_low_confidence): capacity eviction and the outcome / contradiction revision channels depend on live cross-table state and are deliberately not predicted here. - memforge_explain MCP tool wired to the real client method; TS + Python SDKs including both resilient wrappers; OpenAPI entries - query cache key extracted to queryKey() in cache.ts so the explain flag's participation in the key is unit-testable without Redis - warm_id validated to int8 range at REST and MCP boundaries; invalid agent ids on /explain return 400 like sibling routes No schema migration — pure code feature.

charset=UTF-8 Content-Transfer-Encoding: 8bit Feature 3 of the Phase 5 split (umbrella #129): MemForge learns which events tend to follow which, and can answer "what led here" and "what happens next". - causal_edges table (migration-v3.10.sql + canonical schema, RLS, agent-scoped FKs to warm_tier with CASCADE) - Sleep Phase 6.1 mines memory_sequences for repeated content-level A→B patterns (md5 of 50-char prefixes, the Phase 5.5 technique) — the umbrella's row-pair grouping was unsatisfiable under the table's UNIQUE constraint and could never mine an edge. One edge per pattern, anchored to the earliest surviving pair so re-mining updates in place and FK cascade self-heals evicted anchors. Not skip-gated: the phase's input accumulates independently of its own change history, so the zero-change gate would permanently disable mining for young agents. Count surfaces as SleepCycleResult.causal_edges_updated. - getCausalChain(): recursive CTE traversal (causes|effects, depth clamped 1-10, 50-row cap, ordered depth then strength) - predict(): context match → outgoing edges → ranked events. probability = confidence × (1 − e^(−strength/30)) — monotonic, never saturated (raw strength × confidence clamps to 1.0 for virtually every mined edge). Shared-pool matches are excluded from the cause-id list (different id space than warm_tier), and effects are confined to the requested namespace. - GET /memory/:id/causal + POST /memory/:id/predict, memforge_causal_chain + memforge_predict MCP tools wired to real client methods, TS + Python SDKs incl. resilient wrappers, tool-definitions, OpenAPI - tests/causal-graph.test.ts: 39 tests (traversal incl. cycles/clamps/ cap/ordering, predict incl. namespace + pool-collision, Phase 6.1 mining incl. cv weighting + anchor stability + true re-confirmation step, pruning, HTTP status paths, migration shape + RLS) Co-Authored-By: Claude Fable 5 Claude-Session: https://claude.ai/code/session_011xCqQo49d3CEbn6oEvb3Ru --- package.json | 3 +- python/memforge/client.py | 37 ++ python/memforge/resilient.py | 14 + schema/migration-v3.10.sql | 56 +++ schema/schema.sql | 31 ++ src/app.ts | 80 +++- src/client.ts | 31 ++ src/mcp.ts | 59 +++ src/memory-manager.ts | 117 +++++ src/openapi.ts | 103 +++++ src/schemas.ts | 8 + src/sleep-cycle.ts | 98 ++++ src/tool-definitions.ts | 27 ++ src/types.ts | 51 +++ tests/causal-graph.test.ts | 845 +++++++++++++++++++++++++++++++++++ 15 files changed, 1558 insertions(+), 2 deletions(-) create mode 100644 schema/migration-v3.10.sql create mode 100644 tests/causal-graph.test.ts diff --git a/package.json b/package.json index 665757a..71eab99 100644 --- a/package.json +++ b/package.json @@ -45,12 +45,13 @@ "test:dreams-compat": "node --import tsx/esm --test tests/dreams-compat.test.ts", "test:dreams-anthropic": "node --import tsx/esm --test tests/dreams-anthropic.test.ts", "test:dreams-bridge": "node --import tsx/esm --test tests/dreams-bridge.test.ts", - "test": "node --import tsx/esm --test --test-concurrency=1 tests/integration.test.ts tests/llm-paths.test.ts tests/http-api.test.ts tests/cache.test.ts tests/embedding-migration.test.ts tests/outcome-revision.test.ts tests/reflection-revision.test.ts tests/selective-forgetting.test.ts tests/multi-device.test.ts tests/dream-runs.test.ts tests/dreams-compat.test.ts tests/dreams-anthropic.test.ts tests/dreams-bridge.test.ts tests/sentiment-tagging.test.ts tests/adaptive-sleep.test.ts tests/epistemic-confidence.test.ts tests/explainable-memory.test.ts", + "test": "node --import tsx/esm --test --test-concurrency=1 tests/integration.test.ts tests/llm-paths.test.ts tests/http-api.test.ts tests/cache.test.ts tests/embedding-migration.test.ts tests/outcome-revision.test.ts tests/reflection-revision.test.ts tests/selective-forgetting.test.ts tests/multi-device.test.ts tests/dream-runs.test.ts tests/dreams-compat.test.ts tests/dreams-anthropic.test.ts tests/dreams-bridge.test.ts tests/sentiment-tagging.test.ts tests/adaptive-sleep.test.ts tests/epistemic-confidence.test.ts tests/explainable-memory.test.ts tests/causal-graph.test.ts", "test:multi-device": "node --import tsx/esm --test tests/multi-device.test.ts", "test:sentiment-tagging": "node --import tsx/esm --test tests/sentiment-tagging.test.ts", "test:adaptive-sleep": "node --import tsx/esm --test tests/adaptive-sleep.test.ts", "test:epistemic-confidence": "node --import tsx/esm --test tests/epistemic-confidence.test.ts", "test:explainable-memory": "node --import tsx/esm --test tests/explainable-memory.test.ts", + "test:causal-graph": "node --import tsx/esm --test tests/causal-graph.test.ts", "benchmark:longmemeval": "node --import tsx/esm benchmarks/longmemeval/run.ts", "benchmark:download": "node --import tsx/esm benchmarks/longmemeval/download.ts", "benchmark:ingest": "node --import tsx/esm benchmarks/longmemeval/ingest.ts", diff --git a/python/memforge/client.py b/python/memforge/client.py index ece5380..3be5668 100644 --- a/python/memforge/client.py +++ b/python/memforge/client.py @@ -305,6 +305,43 @@ async def explain_memory(self, agent_id: str, warm_id: str | int) -> dict[str, A raw = await self._get(f"/memory/{agent_id}/explain", {"warm_id": str(warm_id)}) return raw if isinstance(raw, dict) else {} + #

charset=UTF-8 Content-Transfer-Encoding: 8bit Feature 4 of the Phase 5 split (umbrella #129): Sleep Phase 5.11 distills cross-cutting principles from accumulated meta-reflections into a queryable abstractions store. - abstractions table (migration-v3.11.sql + canonical schema): level CHECK (principle|strategy|mental_model), stored md5 content_hash with UNIQUE (agent_id, level, namespace, content_hash) — the umbrella's ON CONFLICT DO NOTHING had no conflict target and would have duplicated every principle every cycle. RLS + grants. - Phase 5.11: gated on LLM presence, token budget, and >= 3 meta-reflections; prompt carries the codebase-standard injection guard, wraps reflection content via wrapUserContent, and states the schema's own limits (max 10, under 2000 chars, empty-array escape) so one overlong item does not sink the batch silently. Re-derivation is corroboration: ON CONFLICT keeps GREATEST confidence and revives a deactivated principle only when the fresh derivation is confident (>= 0.5); the conditional WHERE keeps change counts honest. Age-based deactivation of stale sub-0.2 principles. Not skip-gated (input accumulates independently). Cancellation checkpoint before the LLM call so canceled dream runs stop paying. runPhase now records real per-phase token spend in sleep_phase_analytics; count surfaces as SleepCycleResult.principles_extracted. - getAbstractions()/getPrinciples(), GET /principles + /abstractions routes, memforge_principles + memforge_mental_models MCP tools wired to real client methods (honest description: only 'principle' is auto-extracted today), TS + Python SDKs incl. resilient wrappers, tool-definitions, OpenAPI with shared Abstraction component. - tests/abstractions.test.ts: 39 tests — read paths, extraction incl. dedup/revival/confidence-raise/skip-gate immunity/token attribution/ budget + window gates/malformed + schema-invalid + missing-key LLM output, deactivation age and scope boundaries, ordering tiebreak, HTTP status paths, migration shape + RLS.

charset=UTF-8 Content-Transfer-Encoding: 8bit Feature 7 of the Phase 5 split (umbrella #129), the final feature: bootstrap a new agent from an experienced one. - bootstrapAgent(): one atomic transaction copying established warm memories (as epistemic 'inferred', 0.5x importance/confidence, _transferred_from provenance), active procedures, and active principles from source to target. Set-based INSERT..SELECT with dedup BEFORE each LIMIT so already-carried knowledge frees its cap slot (the umbrella looped N+1 with no-op ON CONFLICTs — procedures has no unique constraint at all). Memory dedup is namespace-scoped and content-exact (organic rows hash content differently, so equality is the only honest check). Warm-tier creates carry hash-chained audit records ('bootstrap' trigger) like consolidation and cold-restore do. - Phase 5.12 promotion now also considers 'inferred' rows meeting the same evidence bar — bootstrap is the first mass writer of inferred status, which was previously terminal: excluded by every epistemic filter except 'all' with no path out regardless of corroboration. - POST /memory/:id/bootstrap (path agent = target; Zod-validated body incl. agent-id regex and 0-1000/0-100 caps), memforge_bootstrap MCP tool with its own agent-pair validation and a real executor, TS + Python SDKs incl. resilient wrappers, tool-definitions, OpenAPI. Docs state honestly: principles carry no provenance marker (no metadata column); transferred rows are FTS-searchable immediately, semantic after embedding backfill, filter-visible after promotion. - No schema migration (audit trigger comment updated in schema.sql). - tests/bootstrap.test.ts: 22 tests — transfer semantics per category, discounts + provenance, namespace scoping incl. the cross-namespace dedup regression, per-category caps incl. principle slot-starvation regression, idempotency, organic-content dedup, transaction rollback via sabotage trigger, inferred->established promotion, auto-register, HTTP status paths.

charset=UTF-8 Content-Transfer-Encoding: 8bit The final Phase 5 slice — the Feature 1 remnant that never landed with PR #137. Phase 2.5 conflict resolution stops encoding noise as fact. - When the multi-factor score gap between two conflicting live memories is at most one point (one factor's worth of noise on the quantized integer scale), both are marked epistemic_status='contested' and the conflict resolves with a contested(...) strategy and no winner. The umbrella used a relative 20% threshold, which inverts on small integer scores (pure-noise 1-vs-0 reads as decisive, well-evidenced 6-vs-5 as contested) and is distorted by the mutual +100 supersession offset — the absolute delta is immune to both. - Superseded rows never contest: supersession is an absolute signal, and marking stale facts contested would resurface them as live disputes. - Contested is not terminal (the trap this same stack fixed for 'inferred'): Phase 5.12 promotes contested rows that earn the corroboration bar, and a decisive re-resolution of the dispute clears the winner's badge back to provisional. - tests/contested-conflicts.test.ts: 9 tests — close-call semantics, the exact one-vs-two-point boundary, winner/loser path preservation incl. untouched winner confidence, both-superseded decisiveness, contested recovery via decisive re-resolution. Conflict pairs share an identical relative timestamp (separate INSERTs see different now(), silently handing one side the +3 recency factor). - tests/epistemic-confidence.test.ts: the promotion tests now pin the new behavior (corroborated contested rows promote; uncorroborated ones stay).
