…comoTunedExtractionEnabled
Production engine no longer fires the LoCoMo10-shaped extractors by default.
Five of the six supplemental sources in mergeSupplementalFacts are narrow
LoCoMo-shaped patterns (shared dessert/movie/car-work overlap, beach-walk-
from-photo-tags, sunset-painting subject, dance-crew competition phrasing,
elementary-school co-attendance, pet-affect inventory). They were
observed-fitted from specific LoCoMo10 failures and don't generalize to
arbitrary user memory conversations. Shipping them as unconditional
production behavior leaks benchmark-tuning into the engine.
This commit gates exactly those 5 sources behind a single startup-loaded
feature flag, default off in production. The pre-existing quickExtractFacts
supplemental path stays unconditional — it was already on origin/main and
is not benchmark-shaped.
Threading (no singleton reads in extraction.ts):
- src/config.ts: locomoTunedExtractionEnabled added to RuntimeConfig with
full docstring; env-driven init (LOCOMO_TUNED_EXTRACTION_ENABLED, default
false); appended to INTERNAL_POLICY_CONFIG_FIELDS so benchmark runs can
flip it per-request via the request-body config_override field on ingest
without restarting the core. Mirrors the precedent set by
observationDateExtractionEnabled.
- src/services/memory-service-types.ts: added to IngestRuntimeConfig.
- src/services/consensus-extraction.ts: added to ConsensusExtractionConfig;
surfaced from buildExtractionOptions; widened the runMultipleExtractions
Pick subset.
- src/services/observation-date-extraction.ts: added optional field to
ExtractionOptions with a docstring tying it to mergeSupplementalFacts.
- src/services/extraction.ts:324: passes the option through to
mergeSupplementalFacts via the new options arg, never touching the
config singleton.
- src/services/supplemental-extraction.ts: new SupplementalExtractionOptions
interface; mergeSupplementalFacts takes it as a required third arg.
quickExtractFacts stays unconditionally first in the spread; the 5
LoCoMo-tuned extractors gate on options.locomoTunedExtractionEnabled.
Tests (no env stubbing — flag flows through threaded options):
- src/services/__tests__/supplemental-extraction.test.ts: every existing
case updated to pass { locomoTunedExtractionEnabled: true } so the
existing assertions about LoCoMo-shaped facts still hold (otherwise
default-off would correctly break them). Three new cases under a
"locomoTunedExtractionEnabled gate" describe block:
- flag off + LoCoMo-shape input → no LoCoMo-tuned facts appear
- flag off + pure quickExtractFacts input → quickExtractFacts still
fires (production-safety regression guard)
- flag on + LoCoMo-shape input → existing facts appear (parity check)
- src/services/__tests__/consensus-extraction-runtime-config.test.ts:
three new threading cases with vi.mock-spied extractors. Asserts the
flag arrives in ExtractionOptions for all three extraction backends:
extractFacts (true), chunkedExtractFacts (false), cachedExtractFacts
(true). Existing chunked/cached/extract assertions updated to include
locomoTunedExtractionEnabled: false in their toHaveBeenCalledWith
matchers since buildExtractionOptions now surfaces both fields.
Operator-facing:
- .env.example: documents LOCOMO_TUNED_EXTRACTION_ENABLED under "Internal
retrieval tuning" alongside observationDateExtractionEnabled, with
rationale, default state, and the per-request override path
(config_override field on ingest; AtomicBench wraps via
EVAL_CONFIG_OVERRIDE_JSON).
Behavioral guarantees:
- Flag unset (production default): mergeSupplementalFacts only runs
quickExtractFacts. No regression below origin/main.
- Flag true (benchmark reproduction): all 6 supplemental sources fire,
matching the prior PR #1 HEAD behavior byte-for-byte.
- Per-request override: setting config_override.locomoTunedExtractionEnabled
on a single ingest call flips the flag for that call without process
restart.
Manual validation (the husky pre-commit fallow hook fails creating a
temporary worktree under git-commit's index lock — fallow's check
itself is green when run standalone via `sh .husky/pre-commit`. Bypassing
the broken hook invocation, NOT a failing gate. Issue is tracked
separately):
- npx tsc --noEmit: clean
- npm test: 1199/1199 across 121 test files
- npx fallow audit --base=origin/main: ✓ No issues in 33 changed files
- sh .husky/pre-commit: ✓ No issues in 33 changed files
- Single mergeSupplementalFacts call site in src/ confirmed via grep;
no other code path bypasses the gate.
This unblocks the engine-quality validation experiment: re-ingest LoCoMo10
with the flag off, score against that scope, and the F1 delta vs the
existing flag-on 0.6684 baseline is exactly the LoCoMo-extractor
contribution. That number — not the 0.6684 — is the apples-to-apples
engine-quality comparison against mem0's 0.6755.

- preserve the full benchmark-specific core state on benchmark/locomo10-tuned-extractors - remove the LoCoMo-tuned extractor flag and runtime config plumbing from this PR branch - remove LoCoMo-specific supplemental extractors and tests from the production-targeted diff - keep the remaining generic temporal retrieval and ranking improvements

This PR has been narrowed back to production-generic retrieval improvements.
The LoCoMo/benchmark-tuned extractor work has been removed from this PR branch and preserved on:
benchmark/locomo10-tuned-extractorsThat benchmark branch is for comparison and optimization work only and is not intended to merge to

Fallow passes standalone and during the final commit after clearing git's commit-time index env for the hook process. The hook itself was restored before push; no hook changes are part of this PR.
