- Ultracode wave: 30 high-reach tractable residuals, parallel guided-hand-matching agents (m2c + Ghidra-C cache + asm + actor-struct + S1/S2/S3a playbook), self- validate match_one. 18/30 match_one MATCH (60%); 10/30 whole-binary verified (33%) after sig_unify recovered 2 -> all 10 propagated x134; 2 demo fns caught up - 136/136 byte-identical (R22 clean check-all); REAL +1,610; 1421 dedup groups - KEY FINDING: the match_one->whole-binary gap (60%->33%) is 100% SIG CONFLICTS (shared callees like func_80131CA8 declared inconsistently across parallel agents), NOT codegen. The canonical-sig layer (deferred as low-value) is the ESSENTIAL enabler -> would lift 33% toward 60%. 12/30 are the genuine gcc-quirk tail (DIFF). - Ghidra pre-pass: tools/ghidra_scripts/DecompileFunctions.java (headless batch decompile -> .run/ghidra_c cache; no /mcp needed); 300 tractable targets sized - harness: .run/harvest_wave_s3.js (embedded-targets Workflow; args channel doesn't transit arrays). cost ~1.89M tokens / 30 fns

// DecompileFunctions.java — headless postScript: batch-decompile a list of functions
|
|
// (one hex address per line in arg[0]) and write each function's C to arg[1]/<name>.c.
|
|
// Built for the Phase-17 harvest Ghidra pre-pass: dump whole-program Ghidra-C for the
|
|
// tractable residuals so harvest agents get local/global/callee disambiguation m2c lacks,
|
|
// WITHOUT live-MCP contention (agents read the cached files).
|
|
// Usage: -postScript DecompileFunctions.java <addr-list-file> <out-dir>
