nx_express_lane.nx -- X-XL-002 rung 1: the tutor<->team EXPRESS LANE consumer (operator 2026-06-12: the team must not be a BLACK BOX -- S-class communication everywhere including the command line; tutor tokens go to NOVEL work, not greps). PLAIN LANGUAGE: the tutor (any model) appends verb rows to tutor_in.tsv; THIS organ consumes them EXACTLY ONCE each beat, acts, ACKs every row to team_out.tsv, then writes a SITREP block -- the one-read picture (quantitative lines verbatim from the ledgers + queue counts). A tutor that still greps after this is measured: every legitimate read is a channel row; archaeology shows. verbs: MARKWIRE <id> <log::anchor::green> -> append ||MARK= to that row's gate column (idempotent: a row already carrying ||MARK= is never re-marked); ANSWER/ASK/VISIT-START/VISIT-END -> ACKed (consumption rungs follow: X-XL-004 joins ANSWERs to briefs) exactly-once: ACK key=<epoch>:<verb>:<id> in team_out is the cursor -- a row whose key exists is never re-dispatched (re-run = zero re-work). SITREP block: PULSE-VERDICT + EXAMINER-ARCS + AUTMETER + PAPERGEN-SUM lines VERBATIM (ledger-derived, refuse-to-paraphrase) + queue status counts. Durable: ACK + SITREP -> knowledge/channel/team_out.tsv. Exit 0 = lane duty done; exit 1 = could not read its world. argv[1]=tutor_in argv[2]=team_out argv[3]=queue (gates use scratch; live logs read at fixed paths only when argv absent). license_tier: ORIGINAL
