A rebuild that changed nothing took 269 s, 255 of them rebuilding six unchanged cores from scratch. Each core is now skipped when a hash of everything its build reads matches its stamp; ccache sits in front of the frontend, title and core compilers; the patcher writes a file only when its final text differs; the host signing tool is rebuilt only when its inputs change; and deployment uploads only files whose digest differs from what was last verified on that console (--all for all). No-change rebuild 269 s -> 2.2 s, a port-file edit 2.4 s, a driver change 2.4 s, a forced FBNeo rebuild 77 s -> 2.8 s; deploy of nothing changed 0.3 s, of one edit 12.4 s (full deploy 74 s).
