nx_sota_drift_gate.nx -- THE REFEREE for MEASURED BINDINGS in the SOTA emitter (2026-09-01). Subject: the promoted nx_swcompare_matrix generator END TO END -- since 2026-09-02 the ONE assembler, which composes the SOTA field from nx_swcompare_sota_lib (this gate used to drive nx_swcompare_sota). The defect this guards: a sota page is hand-graded and rots the moment an organ ships (lang.sota said "no LSP, formatter, incremental builds or stepping debugger" a week after all four landed, and the same class recurred within a week of a hand fix). The emitter now lets a grade row carry `=<organ>:<symbol>` before its note and re-measures it on every publish with the one symbol ruler. This gate PLANTS every drift class on a fixture domain in its own /tmp tree (never in the estate's knowledge tree: a gate must not share a fixture with a production beat) and forks the generator in census, html and json modes: STALE-UNDER (grade No, symbol present) -> counted, named, page badge, census still exit 0 UNBACKED (grade Yes, symbol absent) -> counted, named, census REFUSES (exit 1) -- the liar-kill class UNRESOLVED (symbol-only binding, no matrix) and UNREADABLE (organ path absent) -> counted and named an unbound row is NOT counted (the neg-control that keeps the count honest) the drift partition sums to bound The fixture is ASSERTED to have reached its condition before any outcome is asserted, and gv_bite proves the refusal fires on the unbacked fixture and stays silent on the consistent one. exit: 0 GREEN . 1 RED . 3 SKIP (generator or fixture unavailable) license_tier: ORIGINAL No hw writes.
