🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject values that are not RagVectorStore members.
When a caller passes True or 1.0, RagVectorStore(value) resolves the value to USEARCH. RagSession.query then sends the override instead of raising SDKException.invalid_input. Check isinstance(value, RagVectorStore) before conversion.
As per coding guidelines, “Validate all external inputs (URLs, archive members, secure keys, model ids).”

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Guard the score indexing behind the size check.
The CHECK macro records a failure but does not stop execution. If f_def or f_low has fewer than two results, Lines 101-102 index out of bounds and cause undefined behavior. A real regression can then crash the test instead of reporting a failure. The BM25 block above already uses a sized guard. Use the same pattern here.

P2: The cross-WASM provider still accepts invalid per-query topK and scoreThreshold values. Negative topK is clamped to 1, NaN topK falls back to 5, and an out-of-range or NaN scoreThreshold silently returns no chunks. Add the same bounds the native path enforces (topK >= 0, scoreThreshold finite in 0...1) and throw SDKException.invalidConfiguration here.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winReject explicit
topK = 0and omit an unsettopK.
RAGRetrievalOptions.top_kis optional but requires a minimum of 1. The Web builders currently convert an omitted value to0, and ts-proto preserves a defined optional scalar as present on the wire. Therefore, both an explicittopK = 0and an omittedtopKcan reach the ABI as present zero. The ABI accepts zero and silently uses the session default, which violates issue#1102and the proto contract.Reject values below 1. Do not encode zero when the caller omitted

What
The session config bounds
top_kandscore_threshold, but the per-query path (rag.queryandrag.search) copied them straight through. Ascore_thresholdoutside0...1or NaN, or a negativetop_k, was used as-is or silently fell back to the default, so retrieval mis-ranked with no error.Both entry points now reject those values with
RAC_ERROR_INVALID_ARGUMENT, through onevalidate_retrieval_boundshelper beside the BM25/RRF check.One deliberate deviation from the issue:
top_k == 0stays valid, meaning "use the session default". The web SDK already sendstopK: 0for an unset value and documents it that way, so rejecting zero would break callers. Only negativetop_kis an error.Not done: the issue's third item (range annotations on the four proto fields). That is a schema change that also touches
idl/VERSIONandSCHEMA_LOCK, which are already being sequenced across the stack, so it is left for that step.Verification
test_advanced_modality_proto_abi: all new checks pass (negativetop_k,score_threshold1.5, NaNscore_threshold, andtop_k0 accepted). The only failures are the two existing Windows VLM model-path checks, which fail the same way without this change.test_rag_fusion: 14 checks, 0 failures.Stacking
Stacked on #1066 (
fix/web-rag-knobs-cross-wasm-provider-1057), which sits on #1048 → #1017. The diff includes those commits until they merge.Closes #1102

rag.queryandrag.search) now boundstop_kandscore_thresholdlike the session config, so a negativetop_kor ascore_thresholdoutside0...1(or NaN) is rejected withRAC_ERROR_INVALID_ARGUMENTinstead of silently mis-ranking results. The PR also threads BM25, RRF, and vector-store knobs through the whole stack.top_k == 0stays the "use the session default" sentinel that every SDK already sends.bm25_k1,bm25_b), RRF (rrf_k), andvector_storeare validated at the ABI boundary and wired into session config, per-query overrides, the retrieve backend, and all SDK bindings (Kotlin, Python, Swift, Web).VECTOR_STORE_USEARCHis whitelisted on-device; PGVECTOR returnsNOT_SUPPORTEDand unknown enum values returnINVALID_ARGUMENT.VectorStoreenum moved fromsolutions.prototorag.protoandIDL_VERSIONbumped to 1.7.0; proto range annotations on the new fields are left for a separate schema change.Written for commit f1a2920. Summary will update on new commits.
