Single incumbent lane, NO duplicate created. Lane identity: ms-wi5-build (pi terra:high, default tmux socket, co-located mosaic-100). Branch feat/832-receipt-challenge-protocol off main e522b22f. Build directive (durable /home/hermes/agent-work/dispatch/wi5-832-build-directive.txt sha256 637a33f421ed2b3d7e80bd9425bde06eae10ec4872fecf0959b42ca8a6245f9f) encodes: STEP-0 4-sha fail-closed authority check; ACs T25/T26/T28/T29 ONLY (T27->WI-6, T30->WI-7); Q2 HYBRID (A in-build red-first for T26 epoch-binding + T29 verbatim-copy against SHIPPED binding; B standalone replay-probe HARNESS for T25/T28 consume-before-promote ORDERING driving SHIPPED transition out-of-process, 3x-isolation-designed, DRIVER-not-reimplementation, NOT self-fired); escalation hatch armed; genuine red-first (test/probe commit before feat commit); NO PR / NO self-review / NO --no-verify; §4 live-mutation freeze. Next lanes on build-land: ms-wi5-code (terra) + ms-wi5-secrev (FRESH OPUS, distinct-principal, !=builder !=WI-3 planner-opus !=ms-wi4-secrev !=any prior SECREV). RoRs -> durable /agent-work/reviews/ + bus form (ii) verbatim+sha256 before merge sign-off (board-push DEFERRED per accepted node_modules hygiene hold).
