P5-T4: tools/sf3_match provides range/plan/build/gate. It compiles a C candidate with the identified toolchain (egcs-2.91.66 psx, -O2 -G0 -mno-split-addresses), compares the exact instruction range byte-for-byte against the original, and builds the address-ordered executable from the tracked registry config/regions.tsv (header 0x800 + data gaps + C regions, LMA 0x800, metadata discarded). Promotes the Phase 4 ordered workflow from an ignored experiment to tracked tooling. Verified: make gate with an empty registry and with one real C region both reproduce SHA-1 e173426c...; the Phase 3 baseline is unchanged and green; the synthetic suite is now 50 tests including deliberate-corruption failures and safe refusal of an existing destination. No ROM-derived material is tracked.
