nx_dedupe_source.nx

nx_dedupe_source.nx -- CLI: resolve a seq207/seq169 dual-copy source divergence the sovereign way. The RESOLUTION half of the mgmt build guard's DETECTION (ma_build_dup_divergent). Reusable ecosystem-wide. usage: nx_dedupe_source --kat (self-test: reconcile/no-op/refuse/idempotent oracle) nx_dedupe_source <target> [canonical_dir] [shadow_dir] nx_dedupe_source check <target> [canonical_dir] [shadow_dir] The directory pair is OPTIONAL and defaults to the historical _hdl_build <- runtime pair, so every existing caller is unchanged. It exists because the DETECTOR (nx_dup_source_check) discovers ~13 source trees while this reconciler knew only two -- hazards in bin/, _retired/ or a nested runtime/runtime/ reported dual_copy:0 and could never be cleared, leaving the board permanently RED. license_tier: ORIGINAL expect_exit: 0 genealogy: seq207 dual-copy class
