feat: add medical domain support behind feature flags by AlexMikhalev · Pull Request #551 · terraphim/terraphim-ai

AlexMikhalev · 2026-02-22T11:49:02Z

Summary

Adds medical domain support to terraphim-ai behind medical feature flags, enabling the medgemma-competition project to use terraphim-ai crates instead of maintaining separate implementations.

Changes by crate:

terraphim_types: Add MedicalNodeType (27 variants) and MedicalEdgeType (60+ variants) enums behind medical feature. Extend Node and Edge with optional medical fields.
terraphim_rolegraph: Add MedicalRoleGraph wrapper with typed nodes/edges, IS-A hierarchy, symbolic embeddings, and medical_loaders module (SNOMED RF2 + PrimeKG CSV import). Add RoleGraph::new_sync() constructor.
terraphim_automata: Add SNOMED/UMLS entity extraction behind medical feature (EntityExtractor, UmlsExtractor, ShardedUmlsExtractor, artifact serialization).

Key design decisions:

All medical code behind #[cfg(feature = "medical")] -- zero impact on existing users
MedicalRoleGraph wraps RoleGraph and uses magic_pair for edge encoding
Symbolic embeddings use Jaccard similarity (0.7) + path distance (0.3)
SNOMED RF2 and PrimeKG loaders populate MedicalRoleGraph directly

Stats:

17 files changed, 4,815 insertions, 10 deletions
72+ tests for medical rolegraph features
No changes to existing non-medical code paths

Test plan

cargo check --package terraphim_types --features medical
cargo test --package terraphim_rolegraph --features medical
cargo check --package terraphim_automata --features medical
cargo check --workspace (no regressions without medical feature)
cargo test --workspace (existing tests still pass)

Changes: - terraphim_automata: Add file existence check before loading thesaurus from local path - terraphim_automata: Use path.display() instead of path in error messages to fix clippy warning - terraphim_service: Check for "file not found" errors and downgrade from ERROR to DEBUG log level This fixes issue #416 where OpenDAL memory backend logs warnings for missing optional files like embedded_config.json and thesaurus_*.json files. Now these are checked before attempting to load, and "file not found" errors are logged at DEBUG level instead of ERROR. Related: #416

Add tempfile = 3.0 to dev-dependencies to fix build failure in examples that use tempfile. Fixes workspace build error in terraphim_graph_embeddings_learnings example.

…elegram and Discord channels Fix GAP-001 and GAP-002: - Remove partial token logging_in_rust_shuttle_guide from Telegram channel startup - Discord channel already had safe logging_in_rust_shuttle_guide (verified) security improvement: Bot tokens are no longer logged, even partially. This prevents accidental token exposure in log files.

…P-003) Add code_reviews to verify outbound messages are properly dispatched in gateway mode. code_reviews cover: - Basic message dispatch to single channel - Message routing to multiple channels (telegram/discord) - Graceful practical_guide_to_error_handling_in_rust of unknown channels - High-throughput dispatch (making_python_100x_faster_with_less_than_100_lines_of_rust messages) These code_reviews verify the critical fix for gateway outbound dispatch that was how_to_implement_a_naive_bayes_classifier_with_rusted in PR #529.

The security fix commit (1226699) incorrectly bundled workspace restructuring: - Removed terraphim_server, terraphim_firecracker, desktop/src-tauri, terraphim_ai_nodejs from members - Changed default-members from terraphim_server to terraphim_tinyclaw The follow-up dd4881b added desktop/src-tauri to exclude list, breaking the desktop_mcp_integration test (package not found in workspace). Restore workspace to match upstream/main: - members includes terraphim_server, terraphim_firecracker, desktop/src-tauri, terraphim_ai_nodejs - default-members = ["terraphim_server"] - exclude list matches upstream (no desktop entries) Co-Authored-By: Terraphim AI <noreply@terraphim.ai>

… flag Add MedicalNodeType (27 variants) and MedicalEdgeType (65 variants) enums for clinical and biomedical knowledge graphs, covering PrimeKG molecular relationships, clinical workflow temporal/diagnostic/severity edges, and treatment detail relationships. Extend Node and Edge structs with optional medical fields (node_type, term, snomed_id, edge_type) gated behind #[cfg(feature = "medical")] with serde skip_serializing_if for backward compatibility. Includes MedicalNodeMetadata struct and comprehensive tests. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…gs behind medical feature Phase 2 implementation: Extends terraphim_rolegraph with medical-specific capabilities gated behind the `medical` feature flag. - Add `symbolic_embeddings` module with Jaccard + path-distance similarity, IS-A hierarchy traversal, and RwLock-cached nearest-neighbor queries - Add `medical` module with MedicalRoleGraph wrapping RoleGraph via composition, providing typed nodes/edges, IS-A parent/child tracking, SNOMED ID mapping, treatment lookup, contraindication checking, and on-demand embedding builds - Add `medical` feature to Cargo.toml forwarding to terraphim_types/medical - 43 new tests covering hierarchy traversal, similarity properties, caching, edge encoding, and embedding invalidation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…ehind medical feature Port medical entity extraction modules from medgemma-competition into terraphim_automata as an optional feature gate. This adds: - snomed.rs: SNOMED CT data structures (SemanticType, SnomedConcept, SnomedMatch) - umls.rs: UMLS dataset loading from TSV (UmlsConcept, UmlsDataset, UmlsStats) - umls_extractor.rs: Aho-Corasick based UMLS entity extraction - medical_extractor.rs: SNOMED-based entity extraction with hierarchy support - sharded_extractor.rs: Sharded daachorse extractor for large pattern sets - medical_artifact.rs: bincode+zstd serialization for fast artifact loading All modules are gated behind cfg(feature = "medical") with optional deps (daachorse, zstd, anyhow). Existing tests pass without the feature enabled. 27 new tests pass with the medical feature. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…OMED/PrimeKG import Phase 5 Step 1: Port SNOMED RF2 and PrimeKG CSV loaders into terraphim_rolegraph behind the medical feature flag. This enables consumers to build a MedicalRoleGraph from external data sources without requiring an Aho-Corasick thesaurus. - Add MedicalRoleGraph::new_empty() synchronous constructor - Add RoleGraph::new_sync() for non-async construction - Add medical_loaders module with PrimeKG CSV import and SNOMED RF2 loading - Add csv and anyhow as optional dependencies gated on medical feature - Port parse_node_type, parse_edge_type from terraphim-kg - 22 new tests covering all loader functions and edge cases Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

… sharded patterns ShardedUmlsExtractor's sort+dedup_by silently dropped CUI mappings when multiple concepts shared the same term (e.g., "cold" = C0009264 "Common Cold" AND C0234192 "Cold Temperature"). Replace with a merge that groups all CUIs per term, emits one match per CUI during extraction, and logs a warning for multi-CUI terms. Artifact serialization updated accordingly. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Change magic_unpair to use f64 instead of f32 for sqrt, preventing precision loss with SNOMED-scale IDs (100M-900M range) - Fix incomplete overlap detection in umls_extractor and medical_extractor that missed the containment case (new match fully containing existing) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add outgoing_edges and incoming_edges AHashMaps to MedicalRoleGraph. Rewrite get_treatments() and check_contraindication() to use the index instead of scanning all edges, reducing complexity from O(edges) to O(degree) -- critical for PrimeKG's 4M+ edges. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Instead of hardcoding all SNOMED concepts as Disease, parse the semantic tag from the Fully Specified Name (e.g., "(procedure)", "(substance)") to determine the correct MedicalNodeType. Placeholder nodes from relationships now default to Concept instead of Disease. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

E2E Pipeline Verification Results (49/49 PASS)

After fixing all P0/P1 issues and migrating medgemma-competition consumers, the full end-to-end pipeline passes all checks:

Test Coverage

Section	Checks	Status
Data Files (SNOMED 10KB, UMLS 209MB, CPIC 16KB, TSV 789MB)	4	PASS
Knowledge Graph (18 nodes, 14 edges, IS-A hierarchy)	26	PASS
Entity Extraction (Aho-Corasick, 7 entities in 0.012ms)	4	PASS
UMLS Artifact (1.4M patterns, 4.3M concepts, 3 shards)	3	PASS
SNOMED Thesaurus (49 terms)	4	PASS
PGx Validation (CYP2C19, CYP2D6 metabolizers)	2	PASS
MedGemma Inference (Mock: Osimertinib 80mg, 92% conf)	1	PASS
Full 6-Step Consultation Pipeline	5	PASS
Total	49	ALL PASS

Key Metrics

UMLS artifact load: ~14s (199MB zstd decompressed)
Entity extraction: 0.012ms for 7 entities from clinical note
Full pipeline: ~102ms (mock inference)
Symbolic similarity: NSCLC/SCLC = 1.0 > NSCLC/Breast = 0.62 (correct ontological ordering)

Fixes Applied (from code review)

P0-1: magic_unpair f32->f64 precision (SNOMED IDs 100M-900M)
P0-2: Overlap detection in UMLS/SNOMED extractors (interval check)
P1-1: Adjacency index for O(degree) treatment/contraindication lookups
P1-2: ShardedUmlsExtractor multi-CUI term preservation
P1-3: SNOMED FSN semantic tag parsing for node types

CI Status

All critical Rust checks pass: Compilation, Format, Unit Tests (3m41s), Security Audit, Integration Tests, E2E Tests, WASM Build. Failing checks are Python tests (unrelated) and Benchmark/Clippy (pre-existing branch issues from prior commits).

medgemma-competition Integration

Committed to main: 2e317ff - e2e pipeline example proving terraphim-ai crates are fully integrated.

Clippy Fix Pushed (3c478b37)

Fixed the 4 Clippy errors that were causing the lint-and-format check to fail:

terraphim_types/src/lib.rs:

NormalizationMethod: manual Default impl replaced with #[derive(Default)] + #[default] attribute
GroundingMetadata: manual Default impl (all None) replaced with #[derive(Default)]

terraphim_rolegraph/src/medical.rs:

2x map_or(false, ..) replaced with is_some_and(..) in check_contraindication()

All 78 medical tests still pass. Clippy now passes clean for both terraphim_types and terraphim_rolegraph with medical feature.

Note: The remaining CI failures (terraphim_multi_agent clippy, Python tests, Benchmark) are pre-existing and unrelated to the medical-extensions changes.
