@jeswr/rdf-engine

T-070 implements lazy single-document parse/serialize, SHACL validation and RDFC-1.0
canonicalization. The Node entry uses the prebuilt wasm-node module; the browser entry accepts
a configured wasmUrl and ships a content-hashed static-asset copy script. Keep Sparq pinned
to 0.1.5 and feature-detect optional serialize/parseShaclCompact bindings.

The testing entry is n3-backed and must never import Sparq at runtime. Its JSON-LD operations
and blank-node canonicalization throw FakeEngineUnsupportedError. Its validator is injectable,
defaulting to a conforming empty report; tests of SHACL semantics must use the real engine.

Always release temporary WASM stores in finally. Returned datasets are materialized into
JavaScript memory. The shared contract runs on both engines; JSON-LD, SHACL and blank-node
canonicalization have a separate real-engine contract. Preserve the 90% coverage gate, the
installed-WASM size test and bench/bundle.json measurement (gzip level 9).

The shared contract also covers LocalIndex graph lifecycle (put/remove/has/size/dispose).
Real indexes own one WASM store; engine disposal releases every owned index. T-071 owns
the later query/stream, snapshot/restore, persistence and LRU surfaces.

Before implementation, read SDK core ADR-001 D4 and ADR-007-sparq-wasm.md in
solid-suite-planning/specs/sdk-core/, alongside this repository's AGENTS.md.

Keep development tool versions aligned with the root manifest. The pinned pnpm 10.4.1 with
ignore-scripts requires local tool declarations for filtered scripts.

Validate changes with this package's lint, build, typecheck, and test scripts.
