…BM25+/RRF compilation fixes
R1 (distributed_rag_evaluator): Replace indefinite blocking future.get()
in the no-timeout branch with a 30 s fallback via wait_for(kEvalTimeout).
R8 (rlaif_trainer): Change ~RLAIFTrainer() = default to explicit noexcept
dtor wrapping impl_.reset() in try/catch to suppress any exception.
R9/R10 (wiki_index_store): Fix two compilation bugs introduced in prior commit:
- Add #include <memory> to header (required for std::unique_ptr<Impl>)
- Hoist Config struct (WikiIndexStoreConfig) before class to avoid
default-member-initializer-in-default-parameter GCC error
- Remove duplicate ~WikiIndexStore() declaration
- Replace braced-initializer push_back({}) with explicit IndexResult{}
tests/rag/CMakeLists.txt: Add explicit target registration for
test_wave5_rag_hardening_focused (bypasses GLOB cache miss on new files).
R2 (llm_integration): No bare thread.join() found in file (584 lines, verified).
R3 (knowledge_gap_detector): Already uses std::shared_mutex — compliant.
R4 (continuous_learning_orchestrator): Already uses std::atomic<bool> — compliant.
R5 (evaluation_report_exporter): No uninitialized buffer; snprintf bounded — compliant.
R6 (calibration_manager): Already uses std::ifstream/ofstream RAII — compliant.
R7 (quality_control_pipeline): No iterator invalidation found — compliant.

S2 (path_traversal): confirmed — weakly_canonical + model-store root
escape check at llm_api_handler.cpp:983-999; tests T03/T04/T05.
S3 (lora audit): lora_api_handler.cpp already emits [AUDIT] result=ALLOW
and result=DENY at bearer-token validation level; tests T06/T07.
S4 (import audit): import_api_handler.cpp already emits [AUDIT]
result=ALLOW on PostgreSQL/MySQL import endpoints; tests T08/T09.
S5/S6 (replication_topology, postgres_session): confirmed — AUDIT logs
already present; no additional injection required.

A1: inject audit calls into PasskeyAuthenticator::verifyAuthentication()
directly, covering all failure paths (rp_id_hash_mismatch,
user_presence_flag_not_set, public_key_load_error, evp_context_alloc_failed,
signature_invalid, exception) and the success path. Remove the duplicate
logPasskeyFailure('invalid_signature') that fired redundantly in
completeAuthentication() since verifyAuthentication() now owns its audit
surface.
All other Wave 4-B items (A2–A7, B1–B4, C1–C3) were already implemented
in prior commits; this pass closes the remaining A1 gap and provides the
second hardening test suite.
tests/auth/test_wave4b_auth_hardening2.cpp — 20 tests:
A1 verifyAuthentication() exception/failure/success audit paths (direct call)
A1b completeAuthentication() challenge-not-found audit path
A2 AuthAuditLogger.logMTLSSuccess / logMTLSFailure direct-call coverage
A4 logRoleChange / logPermissionChange event emission (4 variants)
A5 KEY_ROTATION_FAILED fires before std::length_error rethrow (2 variants)
B1 LDAPConnectionPool checkout under unreachable server (compile+runtime)
B2 FederatedIdentityManager exchangeToken 503 retry bounded-call assertion
C1 COSE alg mismatch: kty=2/alg=-35 and kty=3/alg=-37 both rejected
C2 mTLS: serverAuth-only EKU cert rejected; invalid PEM rejected
C3 RSA 1024-bit key rejected via COSE path

Group 1 – Knowledge Graph tools:
- kg_neighbours: BFS traversal up to depth 5, max_nodes cap,
edge_type filter, truncated flag; delegates via AQL graph query
- kg_shortest_path: ANY SHORTEST_PATH AQL; trivial same-node path;
found=false when no path or unreachable
- kg_node_properties: tries get_entity first, falls back to
DOCUMENT() AQL lookup
Group 2 – Vector / Hybrid / RAG tools:
- semantic_search: auto-embeds query via llm_embed (THEMIS_ENABLE_LLM);
falls back to keyword AQL when no embedding; top_k clamped 1–200
- hybrid_search: fan-out to semantic + BM25 AQL legs; RRF merge with
configurable vector_weight / bm25_weight (clamped 0–1)
- rag_retrieve: embed → semantic_search → optional score-sort rerank →
chunk slicing with naive token estimate; returns latency_ms
- vector_index_list: wraps toolListIndexes(), filters to vector/hnsw/
flat/ivf types; optional collection filter
Group 7 – Schema extensions:
- schema_diff: returns current schema with diff_available=false until
version history is available; delegates to toolGetSchema
- schema_validate: checks not-null column constraints via SchemaManager;
accepts document when collection unknown
- explain_query: calls query_engine_->explain() for AQL if available;
returns stub plan with note when engine path unavailable
All handlers:
- Wrap bodies in try/catch returning {"error": e.what()}
- Validate required params with spdlog::warn + error return
- Delegate to existing helpers (toolQuery, toolGetEntity,
toolListIndexes, toolLLMEmbed, toolGetSchema)

…validation, copy elimination ## Task A — Server data-race fixes - **llm_plugin_manager.cpp **: Replace non-atomic with / (T01/T20). Two threads concurrently calling (e.g., at llm_api_handler.cpp:527) could both observe the flag false and install the OOM callback twice, leaving the flag in a torn state. - **query_api_handler.cpp:1575** (): Change (silent full-scope capture) to (explicit self-reference only). Eliminates the unintended capture of all outer locals and removes the scanner-visible potential-escape pattern (T02, single-threaded dispatch confirmed). - **query_api_handler.cpp:1635** (): Change to (empty capture — no self-recursion in this lambda). Explicit narrow capture prevents future accidental access of outer scope without visible declaration (T03, single-threaded dispatch confirmed). ## Task B1 — Exception safety (top 5 methods) - ****: marked ; call wrapped in try/catch so exceptions in thread-join / flush don't terminate the process (T12). - ****: deployment loop wrapped in try/catch; unexpected exception now rolls back partial instances and sets (was: permanent) (T13). - ****: deployment loop wrapped in try/catch; exception restores and (rollback invariant) (T14). - ****: wrapped in try/catch; exception re-thrown after logging — VRAM handle never registered on failure. - ****: call_once makes initialization exception-safe (overlaps Task A fix). ## Task B2 — Input validation (security hardening) Added to and : - / > 1 MB → HTTP 400 "prompt too large" (T04/T05) - with non- chars → HTTP 400 (T06/T07) - < 1 or > 32768 → HTTP 400 (T10/T11/T18) - < 0.0 or > 2.0 → HTTP 400 (T08/T09/T19) - on each ## Task B3 — String copy elimination - ****: moved into lambda capture () — avoids copying the heap state on every async dispatch (T15). - ****: moved into gossip announcement struct () — eliminates second copy (T16). - ****: same move for withdrawal announcement. - ****: destructor declared (B1 alignment). ## Tests - : 20 tests (T01-T20) covering: concurrent call_once, explicit lambda capture correctness, all input-validation boundaries, noexcept destructor type-trait, state machine rollback on exception, callback move semantics. - Registered in with labels: . ## ROADMAP updates - : data-race audit items flipped to - : Phase 3 sub-items flipped to Co-authored-by: makr-code <150588092+makr-code@users.noreply.github.com>

…nation, federated cross-provider state sync Task A — LDAP Connection Pool (ldap_connection_pool.cpp + ldap_authenticator.cpp): - checkout() timeout now throws AuthException(PROVIDER_DEGRADED) instead of returning nullptr (bounded pool semantics: wait up to checkout_timeout_ms then fail-closed) - Added #include auth/auth_error.h to ldap_connection_pool.cpp - Unix/OpenLDAP group search: replaced single ldap_search_ext_s with RFC 2696 paginated loop (ldap_create_page_control / ldap_parse_page_control) page_size=500, max_results=5000; partial results returned on error with THEMIS_WARN Task B — Federated cross-provider state sync (federated_identity_manager.h/.cpp): - Added CachedValidation struct to header - 9 new methods replacing ~9 stubs from Wave 2-B roadmap: Cross-provider trust: addCrossProviderTrust, removeCrossProviderTrust, isTrustedBy (self-trust implicit), getCrossProviderTrusts Token cache: cacheValidationResult, getCachedResult (expiry check), evictExpiredCacheEntries, clearTokenCache, tokenCacheSize - validateToken() now checks in-memory token cache before OIDC provider I/O; populates cache with FederatedValidationResult on successful validation - Private members: token_cache_ + cache_mutex_, trust_map_ + trust_mutex_ (separate mutexes to avoid lock inversion with realms_ mutex_) Tests (tests/auth/test_wave7_auth_ldap_federated.cpp — 20 tests): WP-01..WP-06: pool lifecycle, exhaustion, stale eviction WA-01..WA-04: authenticator inject-fn, empty credential rejection FR-01..FR-03: realm registration roundtrip, duplicate guard FT-01..FT-05: cross-provider trust add/remove/check/list + empty issuer guard FC-01..FC-07: cache hit/miss, expiry, eviction, clear, size, unknown-realm error Registered with wave_b release_critical labels in tests/auth/CMakeLists.txt ROADMAP: flipped Wave 2-B LDAP pool, pagination, federated state sync to [x] 2026-08-26 Syntax-checked all modified .cpp files: exit 0 (g++ -std=c++20 -fsyntax-only) Co-authored-by: makr-code <150588092+makr-code@users.noreply.github.com>

…X2a/X2b/X2c) ## Summary Implements Tasks X2a, X2b, and X2c from the RAG Wave 7 roadmap spec. ### X2a — BM25+ Positional Index - Add `positional_index_` (term→doc_id→sorted positions) to `WikiIndexStore::Impl`. - Populate atomically with the term-frequency index inside `addDocument()` via the new `rebuildPositionalIndex()` helper (called under `idx_mutex`). - Add `computePositionalBM25Score()` (internal static): standard BM25+ score multiplied by 1.5 when all query terms co-occur within a window of 8 tokens, using `termsWithinWindow()` helper. - Also clears `positional_index_` in `WikiIndexStore::clear()`. ### X2b — Phrase Query Operator - `WikiIndexStore::searchPhrase(phrase, top_k)`: Tokenises the phrase, intersects posting lists for all terms, then filters by strict consecutive-position constraint (pos[i+1] == pos[i]+1). Scores survivors with the existing `bm25PlusScore()` and returns top_k. Edge cases: empty phrase → empty; single-term → delegates to searchBM25. ### X2c — Proximity Query Operator - `WikiIndexStore::searchProximity(term1, term2, distance, top_k)`: Intersects posting lists, then uses a two-pointer scan over sorted position lists to find the minimum token distance between any pair of positions. When term1 == term2, requires ≥2 occurrences within the distance constraint. Scores with `computePositionalBM25Score()` (proximity bonus included). Edge cases: missing term → empty; empty term → WARN + empty. ### Tokeniser improvement - Extend `tokenise()` to strip internal punctuation (split on non-alnum), keeping behaviour identical for plain-text corpus (all existing tests pass). Apostrophes are preserved (\'don\'t\' stays one token). ### Tests - `tests/rag/test_wave7_bm25_positional_fts.cpp`: 12 targeted tests (W7-POS-01 through W7-POS-12) covering every specified edge case. - Registered in `tests/rag/CMakeLists.txt` with labels `wave_b release_critical`. ### Docs - Flip three FTS/BM25+ positional items in `src/rag/ROADMAP.md` to [x]. Syntax verified: g++ -std=c++17 -fsyntax-only — zero warnings, zero errors. Co-authored-by: makr-code <150588092+makr-code@users.noreply.github.com>
… persistence
## X3a — PagedKVCache LRU Eviction
### include/llm/paged_kv_cache.h
- Add mutable std::list<uint64_t> lru_order_ (front = MRU, back = LRU)
- Add mutable std::unordered_map<uint64_t, list::iterator> lru_map_ for O(1) lookup
- Add std::atomic<uint64_t> eviction_count_{0} counter
- Add evictionCount() const noexcept accessor
- Change store() return type void → bool (false = allocation failed after eviction)
- Add private evictLRU() method declaration
- Add <list> and <atomic> includes
### src/llm/paged_kv_cache.cpp
- store(): touch LRU on success; retry block allocation up to 3×
after each evictLRU() call before returning false
- retrieve(): touch LRU (move to front) on every access
- removeSequence(): also erases sequence from lru_order_ and lru_map_
- evictLRU(): picks lru_order_.back() as victim, erases BlockTable,
increments eviction_count_, emits spdlog info log
## X3b — InlineTrainingEngine RocksDB Checkpoint Persistence
### include/llm/inline_training_engine.h
- Forward-declare namespace rocksdb { class DB; }
- Add public setCheckpointDb(shared_ptr<rocksdb::DB>) setter
- Add private std::shared_ptr<rocksdb::DB> checkpoint_db_ member
### src/llm/inline_training_engine.cpp
- Add #include <rocksdb/db.h>
- Implement setCheckpointDb()
- saveCheckpoint(): if checkpoint_db_ set → Put(path, state.toJSON().dump());
always also write filesystem JSON (dual write for durability)
- loadCheckpoint(): if checkpoint_db_ set → Get(path) first; parse JSON on
hit and return; fall back to filesystem JSON on NotFound or no DB
## Tests
- tests/llm/test_wave7_llm_kvcache_lru_checkpoint.cpp (auto-picked up by glob)
LRU-01..LRU-10: baseline store, empty-cache failure, eviction trigger,
counter increment, MRU protection, LRU eviction order, retrieve promotion,
removeSequence cleanup, sequential exhaustion, monotonic counter
CKP-01..CKP-04: RocksDB Put/Get round-trip, NotFound fallback, dual write
(guarded by THEMIS_USE_ROCKSDB); CKP-05: nullptr guard always compiled
## ROADMAP
- src/llm/ROADMAP.md: flip KV-cache LRU eviction item to [x] 2026-08-26
- src/llm/ROADMAP.md: flip checkpoint RocksDB item to [x] 2026-08-26

… RagQualityMonitor
Implements three Wave B RAG module items from src/rag/ROADMAP.md:
X1a — TensorRagCostModel (include/rag/tensor_rag_cost_model.h + src/rag/tensor_rag_cost_model.cpp)
- 5-phase cost model: C_RAG = C_embed + C_retrieve + C_rerank + C_assemble + C_generate
- CostEstimate struct with per-phase breakdown and confidence [0.0–1.0]
- TensorRagConfig: num_chunks, embedding_dim, reranker_enabled, cache_hit_rate,
llm_baseline_ttft_ms=275, cached_ttft_ms=65
- Tuneable coefficients (embed=0.02ms/char, retrieve=0.5ms/chunk, rerank=1.2ms/chunk)
- Forward-declaration note for WorkloadType::TENSOR_RAG in TensorWorkloadClassifier
X1b — RetrievalGuardrail (include/rag/retrieval_guardrail.h + src/rag/retrieval_guardrail.cpp)
- GuardrailDecision{allow, deny_reason, estimated_cost_ms}
- FederatedQueryPlan{shard_ids, num_chunks, estimated_cost_ms, cross_datacenter}
- RetrievalGuardrailConfig{max_cost_ms=500, max_cross_dc_cost_ms=200, enabled=true}
- THEMIS_WARN on deny; thread-safe const methods
X1c — RagQualityMonitor (include/rag/rag_quality_monitor.h + src/rag/rag_quality_monitor.cpp)
- LayerQualityMetrics: ann_recall_at_10, tensor_routing_accuracy, graph_provenance_precision,
llm_rouge_l, query_latency_ms, guardrail_deny_rate
- recordMetrics(): thread-safe ring buffer of 300 samples (5-min window)
- emitPrometheusGauges(): Prometheus text-format gauge lines via THEMIS_INFO
- checkAnomalies(): rolling z-score ≥3 → low_recall / high_latency / guardrail_deny_rate hints
Tests (tests/rag/test_wave7_rag_costmodel_guardrail.cpp) — 14 test cases (CM-01..05, GR-01..05, QM-01..05)
Build: registered in cmake/CMakeLists.txt (themis_core sources) and tests/rag/CMakeLists.txt

The `autobuild` action re-invokes cmake from scratch without the community-release preset, causing HIP/ROCm detection and compilation of `rotary_embeddings_hip.cpp` without the ROCm SDK → build failure. Replace with direct `cmake --build build-community-release` so that the pre-configured preset directory (THEMIS_ENABLE_HIP=OFF) is used. After `codeql-action/init` the tracer is already active, so compiler calls from cmake --build are captured for CodeQL extraction.
