Phase 1a (boot slice): 30 instructions at 0xBFC00000, compiles clean. Phase 1b (instruction coverage): 54 opcodes implemented in strict_translator, 44,629 walker-reachable instructions covered, 0 missing. Phase 1c (function discovery): 76 functions from 2 seeds, 2,988 instructions, 199 call edges, 27 indirect jumps. All validated through StrictTranslator. Phase 1d (indirect control flow): 27 sites classified — 21 A0/B0/C0 dispatch stubs, 4 computed calls, 2 computed tail calls. Ghidra cross-referenced with 0 disagreements. Phase 1e (relocation): ROM-to-RAM copy at FUN_bfc00420 proven with both Ghidra (static) and DuckStation (runtime). 69 address aliases, 68/69 function entries match byte-for-byte in RAM. Normalization rule documented. Includes PRINCIPLES.md and DEBUG.md adapted from recomp-template. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
