nx_gated_edit_multi.nx

nx_gated_edit_multi.nx -- MULTI-EDIT gated applier: apply N exact old->new edits ATOMICALLY, keep iff a verify command's output is byte-identical before/after (else restore ALL + refuse). The multi-edit generalisation of nx_gated_edit -- needed for delegation that adds an IMPORT line AND replaces a body as ONE unit, so the g_check-bulk organs (which don't import the base) consolidate onto a shared lib. argv: <srcfile> <manifestfile> <verifyelf> <verifyarg> manifest: one edit per line, oldfile<TAB>newfile (paths -> no argv escaping). Edits applied in order; each old must occur EXACTLY once in the evolving working copy, else REFUSE-ALL (no partial writes). exit: 0 CONSOLIDATED | 1 REFUSED (restored) | 2 usage/edit-contract (untouched) | 3 verify-before-empty license_tier: ORIGINAL No hw writes (Rule 26).
