nx_pattern_emit3.nx

nx_pattern_emit3.nx -- PATTERN EMITTER: STATE_FLOW (shape 5 of 10 hands-off). The Builder authors a transitions-table state machine CORE from a small spec: <name>_step(state, ev) -> next state, or -1 (ILLEGAL -- the transition is refused, never silently coerced). This is the CMS draft->publish->rollback shape (also the print-job lifecycle and the login-session flow). The table is DATA (from,event,to triples), so the authored core is data-driven per global rule 11 -- no transition logic lives anywhere but the table. Test emission derives REAL KATs from the table itself: every legal row asserted, plus a mechanically-derived illegal pair (max-event+1) asserted refused. Extends nx_pattern_emit (CAPREG231) and nx_pattern_emit2 (CAPREG235). LAWS: struct-free, integer-only, no else-chains (flat ifs), no Claude core logic in the AUTHORED module. license_tier: ORIGINAL
