These workstreams have code changes that are functionally backward-compatible:
These workstreams have code structure but require embedding model / infrastructure:
The following sections document what's been completed, what requires external services, and what the handoff looks like for each workstream.
Status: ✅ Implementation complete; ✅ Local validation possible; ⏳ Live validation pending
Changes:
lib/retriever.js: Configurable RRF_K, FTS_LIST_SIZE, VEC_LIST_SIZE read from settingssrc/config.ts: Added rrfK, ftsListSize, vecListSize advanced settings (rrfK: 10-200, ftsListSize: 10-200, vecListSize: 10-500)MMR: Added mmrLambda setting (0-1, step 0.05, default 0.7); retrieve() uses Number(settings.mmrLambda) || 0.7 in mmrSelect() call
Recency: Added recencyBlend setting (0-1, step 0.05, default 0.8); retrieve() uses recencyBlend * c.score + (1 - recencyBlend) * recencyFactor(pub_date, now)
Search Within Results: Added withinEntryIds optional parameter to retrieve(); integrates with entry filtering; search_rss_cache tool now accepts withinEntryIds string
Local Validation: Can test with constructed vectors; verify MMR diversity, recency blend effects, and withinEntryIds filtering without embedding model
Live Validation Pending: Actual semantic retrieval quality, optimal constant values, performance measurements
Status: ✅ Created; ✅ Local validation possible; ⏳ Live validation pending (embedding model)
File: test/fixtures/embedding-fixture.js
Capabilities:
Test Behaviors:
Usage: node test/fixtures/embedding-fixture.js start [port] then query the endpoints
Status: ✅ Created; ✅ Local validation possible; ⏳ Cannot prove semantic quality without embedding model
File: test/corpus/synthetic-corpus.js
Corpus: 15 articles with manually defined relevance expectations
Relevance Labels (manually defined, NOT generated by implementation):
relevanceAIFramework: high=['a1','a2','a5','a6','a7','a8','a10','a11'], medium=['a3'], low=['a4','a9'], duplicate=['a5','a6']relevanceFunding: high=['a10'], low=all othersrelevanceHistorical: high=['a4'], low=all othersrelevanceEntity: high=['a11'], low=all othersQuery-Relevance Matrix: queryRelevance object with all four query types
Usage: node test/corpus/synthetic-corpus.js outputs corpus summary and label semantics
Status: ✅ Created; ✅ Local validation possible; ⏳ Cannot test Tor routing without infrastructure
File: test/fixtures/searxng-fixture.js
Capabilities:
Test Behaviors:
Usage: node test/fixtures/searxng-fixture.js start [port] then POST to /search
Status: ✅ Implementation complete; ✅ Local validation possible with fixture data; ⏳ Requires embedding model + feed ingestion for full behavioral validation
File: lib/watches.js
Functions:
initWatchState(feedUrl): Initializes watch state for a feedupdateWatchState(watchState, entry): Updates state when article ingested (monotonic firstSeen, content revisions)evaluateWatches(settings, feeds, watchQueries): Core watch evaluation
Key Features:
Local Validation: Can test with constructed entry data and watch queries without embedding model
Full Behavioral Validation: Requires actual feed ingestion and embedding-backed content analysis
Status: ✅ Implementation complete; ✅ Local validation possible with fixture vectors; ⏳ Requires embedding model for full behavioral validation
File: lib/embedding-safety.js
Functions:
Fallback Guarantee: When embedding endpoint fails/malformed, returns a valid Float32Array(768) so the search pipeline doesn't break; search degrades to keyword-only rather than claiming zero results
Local Validation: Can test with constructed vectors; verify dimension checks, model mismatch detection, generation switching decisions
Full Validation: Requires embedding model loaded in LM Studio
Status: ✅ Implementation complete; ✅ Local validation possible with constructed data; ⏳ Requires article content for full behavioral validation
File: lib/context-packaging.js
Functions:
Local Validation: Can test with constructed chunk texts; verify token limits, heading paths, overlap merging
Full Validation: Requires actual article content and embedding model for tokenization verification
Status: ✅ Implementation complete; ✅ Local validation possible with database; ⏳ Requires SQLite database for full metrics
File: lib/diagnostics.js
Functions:
Local Validation: Can run with SQLite database present; read meta table, feeds_state, host_state
Full Validation: Requires SQLite database with populated data (actual plugin deployment)
Status: ✅ Code structure implemented; ⏳ Requires integration with actual database and feed operations
Code Structure (planned but not fully fleshed out in this session):
Integration Points (existing code paths):
refreshFeedsShared() already coordinates refresh operationsinvalidateVectorIndex() already handles index invalidationreindexMissing(), reembedAll() already exist in retriever.jsrunRetention() already handles retention logicpruneRemovedFeeds() already exists in toolsProvider.jsNext Steps: Wire the structured procedures into the existing refresh/maintenance flow; add diagnostics output for each operation
Status: ✅ Code changes documented; ✅ README can be updated; ⏳ Cannot verify "load/verify model" step without embedding model
