feat(node): Phase 1.6+ Slice 3 — ChainSpec builder canonical mock-WASM fallback v0.0.13
Real ChainSpec JSON builder canonical via mock-WASM fallback pattern. Avanza
Origin Chain sin esperar Slice 2c WASM_BINARY resolution canonical (Larihana
pending). Own minimal JSON builder canonical via serde_json puro vs sc-chain-spec
dep canonical (43/44.0.0 trae sc-network mismatch + cid 0.9.0 yanked core2).
Deliverables canonical:
- crates/origin-chain-node/src/chain_spec.rs NEW (240 LOC) — 3 builder fns
(development/local_testnet/mainnet) + load_spec alias resolver + serialize_chain_spec
- crates/origin-chain-node/src/main.rs — new BuildSpec subcommand + build_spec fn
- crates/origin-chain-node/Cargo.toml — Slice 3 dep block canonical doc
- Cargo.toml workspace — sc-chain-spec investigation findings registered
Output JSON canonical compatible con Substrate-canonical sc_chain_spec::GenericChainSpec
schema (12-field structure). Mock WASM hex = "0x" placeholder canonical mientras
Slice 2c land canonical real WASM_BINARY via substrate-wasm-builder.
Verification canonical end-to-end:
- cargo check workspace verde 0.60s
- 10/10 chain_spec tests canonical pass + 75+ workspace tests canonical no regression
- cargo build --release origin-chain-node 2.28s clean
- build-spec --chain dev|local|mainnet|--raw all functional canonical
- BM V2 mainnet allocation verified: 400M+250M+150M+150M+50M = 1B OGC canonical
- Existing subcommands (version, list-presets, print-preset, info) NO REGRESSION
Phase 1.6+ progress: Slices 1+2+2b+3 ✅, Slice 2c WASM pending Larihana,
Slice 4 full sc-service requires Slice 2c canonical resolution.
