needs_full_build() decided the fast path was safe by hashing only config inputs (VERSIONS, package lists, hooks, archives, auto/config, Dockerfile). It never hashed the build logic itself, so a change to build.sh or lib/fast-path.sh counted as a "light" file and the next build silently reused a squashfs produced by the old code. The merged-usr /lib fix in the previous commit only forced a full rebuild by accident (the overlay manifest saw firmware move from lib/ to usr/lib/). hash_heavy_config now covers every *.sh under iso/builder (build.sh, the build-*.sh helpers, lib/*.sh) plus auto/. A change to build logic is now as heavy as a package-list change. config/bootloaders stays excluded (the fast path regenerates the outer ISO layer from it every time). Hash is deterministic (LC_ALL=C sort). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01H2LLuid8PFhBqBPcxXxkQU
