nx_decollide.nx

nx_decollide.nx -- NAME-COLLISION resolver: two DIFFERENT libraries share a basename in two dirs (0 shared functions -- NOT versions of one lib; converging would delete a real module). Keep the CANONICAL copy's name (e.g. the one that is a build target, or the majority), and rename ONLY the other copy to a distinct semantic name + repoint ONLY the importers that resolve it. Sound + FULL-SCALE by construction: the renamed copy keeps its exact bytes (just a new name), so lib-importers are behaviour-preserved and their transitive dependents are provably unaffected -- only the DIRECT importers can change, so we rebuild EVERY buildable direct importer and require byte-identical. Commit iff all match, else restore every source + rename back (never-brick). Handles the build-target case (keep the target's name) and third-dir importers (they resolve the kept copy -> untouched) that nx_split_resolve cannot. argv: <lib> <keepdir> <rndir> <newname> <buildonly-elf> <direct-importer-srcpath>... e.g. nx_decollide nx_debt runtime/_hdl_build runtime nx_debt_strategy _offc/nx_buildonly.elf <importers> (keep the _hdl_build tool as nx_debt; rename the runtime strategy-lib to nx_debt_strategy) exit: 0 DECOLLIDED | 1 REFUSED (all restored) | 2 usage/precondition | 3 filesystem move error license_tier: ORIGINAL No hw writes (Rule 26): edits .nx source + rebuilds only.
