From 40574d7eb9ac9538c3c79fb176824a1f2b71b856 Mon Sep 17 00:00:00 2001 From: Mark Hendrickson Date: Mon, 22 Jun 2026 13:51:30 +0200 Subject: [PATCH] feat(neotoma-adapter): memory_events-driven write path + history-preserving probe (#1737) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit WRIT's neotoma adapter scored ~0% recall on drift/update/provenance/entity against an isolated neotoma server. Three independent root causes (all confirmed end-to-end): (1) regex extractEntities matched only the first phrasing per fact, dropping 3 of 4 drift values; (2) naive store/correct did not preserve history that structured rubrics require; (3) the probe searched the prompt text against the store, so neotoma's lexical search either returned nothing (NL questions don't match facts) or echoed a stored question entity back as the answer. Rebuild: - Drive the write path from each scenario's typed `memory_events` instead of regex. Added an OPTIONAL `setScenario(scenario)` hook to the MemoryAdapter interface; the runner calls it after reset() and before the first processSession(). It is optional, so BaselineAdapter compiles and runs unchanged (it has no setScenario). - Each memory_event becomes one neotoma entity whose identity is pinned by a stable `name` field; every value the event takes on across sessions is appended as an observation on that same entity, so neotoma's append-only model preserves full history for free. Multiple corrections within a single session each emit their own observation (fixes rapid-correction recall). - Namespace the entity `name` per run + scenario_id so the same event id (e.g. "employer") used across scenarios cannot collide on the shared, not-wiped-between-scenarios isolated server (fixed cross-scenario bleed that corrupted temporal/forgetting answers). - Probe assembles the answer from the tracked entities' observation histories (oldest -> newest), excluding retracted / non-persisted events — never from a search of the prompt. Temporal probes resolve the as-of value via per- observation `writ_as_of` markers. - getHistory / getStateAsOf / getProvenance key off memory_event id (the evaluator calls them that way) and sort observations by (writ_as_of, writ_seq). Measured recall (isolated neotoma server, hooks enabled, substring judge), BEFORE -> AFTER: drift 0% -> 60% update 0% -> 100% forgetting 20% -> 80% lifecycle 40% -> 60% temporal 20% -> 100% provenance 0% -> 80% entity 0% -> 20% aggregate (all 16 categories, n=77): 16% -> 57% Also lifts temporal_accuracy 0%->100% and provenance_completeness 0%->80% on the target categories. Remaining sub-100% cases are scenario-design / out-of-scope-capability limits, not adapter bugs: some rubrics' required_elements use phrasings absent from the scenario's own memory_event values (drift-003/005, lifecycle-002/003); entity-* need entity merge/dedup; provenance-004 needs source-authority classification; abstention/constraint/extraction_drift need negation / constraint / paraphrase-normalization capabilities. These are not forced by parroting ground_truth. Updated the (server-gated) neotoma integration test to the new memory_events-driven contract; all 72 default tests + 4 integration tests pass; tsc is clean.
