docs(adr-047): permit WASM-for-shared-compute (amend ADR-007)#18
Merged
Conversation
ADR-007 (jun-12) prohibited all WASM in browser to prevent logic duplication between backend and frontend. This amendment adds §2 distinguishing WASM-for-rendering (still rejected) from WASM-for-shared-compute (now permitted under strict rules). ADR-047 specifies: - Single source rule: same Rust code compiles to native + wasm32 - No WASM to replace existing frontend (cytoscape + elkjs stay) - Feature-gated, opt-in with graceful backend fallback - Connascence audit: algorithms must decouple from CallGraph domain type via GraphLike trait before WASM compilation This unblocks the WASM graph transforms roadmap item. 10 pure-compute algorithms (PageRank, SCC, god_nodes, community detection, etc.) are now eligible for browser-side execution without duplicating backend logic. Changes: - docs/adr/ADR-007-no-wasm-in-browser.md: state → ACCEPTED (amended), add §2 referencing ADR-047 - docs/adr/ADR-047-wasm-shared-compute-amendment.md: NEW ADR Tag: v0.12.16 PATCH (docs)

Summary
Context
ADR-007 (jun-12) prohibió categóricamente WASM en browser para evitar duplicación backend↔frontend. Esto bloqueaba el roadmap item "WASM graph transforms" (PageRank, SCC, community detection en browser sin round-trip al backend).
