- headless DecompileFunctions over 263 uncached ROI-pool fns (MCP stopped, R23): 263 ok / 0 fail / 0 no-func. cache 300 -> 563. ROI-pool fuel now 325/325 cached (28/28 giants, 310/310 reach-134, 7/7 capped) -> the unattended run never needs MCP. - FIX DecompileFunctions.java: key output by entry address func_<UPPERHEX>.c (Ghidra's raw-import default is FUN_<lowerhex>, which every consumer + the existing 300 files miss). Renamed the 263; the tool fix makes re-prefetch reproducible. - build_fuel_manifest.py --emit-prefetch: reproducible uncached-ROI-pool addr-list (for the T7 runbook). 349 reach-1 x1-leverage fns intentionally excluded (P9). - ghidra/ db churn is the MCP-stop no-op save (R23 restart-noise, not staged).

// 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>
