nx_dep_audit.nx

nx_dep_audit.nx -- the ENGINEER+DOCTOR dangling-dep probe (operator 2026-06-13: "build the nishi engineer to one step less than ten seconds [and] have the capabilities to address the errors"). A DANGLING DEP is a `deps` token (field 6) that names NO real queue row. The Engineer FINDS, the Doctor ROOT-CAUSES: one <10s pass classifies each so the finding is actionable, not noise: STATUS-IN-DEPS a lifecycle word (TODO/DONE/...) -- a SIL-umbrella VARIANT whose columns are (parent/program, status) where normal rows are (status, deps); an_core mis-reads it. NOT a missing foundation (e.g. GENEALOGIST-SIL: field5=NOORPHAN-SIL is the real parent, field6=TODO is the status). CROSS-REGISTRY a real row in callouts.tsv (CALLOUT-*) or cred_requests.tsv (CR-*) -- a valid cross-registry dependency, not an error. ORGAN-IN-DEPS an organ name (nx_*) where a ROW-ID belongs -- a category error. LIKELY-RENAME a real queue row shares a strong prefix -> the dep was renamed/typo'd (suggest it). MISSING no match anywhere -- a genuinely absent foundation, file for the owner. TRUE-DANGLING = ORGAN + RENAME + MISSING (STATUS-IN-DEPS = schema variant; CROSS-REGISTRY = valid). It SURFACES + DIAGNOSES + SUGGESTS; it never guess-edits deps (re-point/normalise needs intent). Composes nx_assign_core (DRY: the queue loader + an_streq). SELF-VALIDATING: baked pos (real-row dep -> 0) + neg (ghost dep -> 1). Sub-second single pass. Wired into the pulse (tp_tail_c) as the deps-coherence gate, beside the two no-floating gates (capability_ladder, root_trace). license_tier: ORIGINAL
