Price history client

The neutral client composes the selected installed XL1 native finalized and controlled REST readers, historical Service Kit B4 authority and explicit public archive seeds. createPriceHistoryClient(profile) creates a read-only client; query(query, options) returns price-history-result-v1, and close() aborts and drains its queries and native reader.

parsePriceHistoryProfile(input) validates object or JSON-text configuration without constructing providers or making requests. It returns a detached profile using the same boundary as client construction. Parsing configuration establishes no authority, inclusion, availability or price facts.

Every query names a trusted owner, one fleet or all fleets, source, opaque market, fixed candle width, half-open source-start seconds window and exact native anchor. Authority is evaluated at each carrying block, and equal body roots at distinct native positions remain separate. Original Price roots and native storage envelopes are checked before strict interpretation. Only the admitted native storage _sequence is removed; its value supplies no ordering or time.

Continuation is an untrusted output hint. Every page replays the fixed native anchor and required authority; coverage states how many matching rows preceded the hint. Only complete, exhausted coverage establishes complete enumeration. Missing, unsupported and bounded-out evidence remains explicit. facts-complete reports correlated native/content/authority facts and supplies no economic or consumer settlement verdict.

The closed profile contains URLs, finite owning/client limits and the qualified frozen Price/Gate registry binding. It accepts no credentials, transport/proof callbacks or imported rosters. Decoded work is conservatively reserved across repeated owning calls; reservedDecodedBytes is a cap reservation, not measured throughput. Source collection, aggregation and game policy belong elsewhere.

The implementation follows the selected profile. Actual small-profile, installed-consumer and business-case qualification remain distinct from source existence and deployment.
