executed physical gates
qualified signoffs
Release gates
Frozen as-built configuration
exact CAD/ECAD/firmware/software hashes and received-part identifiers agree with the traveler
OPENMechanical restraint and guards
received assembly inspected; restraint, guards, feet, support frame and exclusion zone signed
OPENProtective-earth and DC reference
jurisdiction and enclosure assumptions frozen; PE continuity and the single proposed DC 0 V/PE bond measured
OPENExternal interruption chain
source disconnect, two contactors, E-stop channels, monitored reset, EDM and service disconnect physically verified
OPENBranch protection coordination
main and all branch protection selected from measured fault/inrush/regeneration evidence and documented clearing limits
OPENHarness acceptance
25 power pairs and all signal links pass conductor, crimp, polarity, insulation, continuity, retention, flex and no-backfeed inspections
OPENReceived-board inspection
controller, carriers and PDU match released candidates and pass assembly, isolation, polarity and unpowered checks
OPENSafety fault injection
E-stop, reset, EDM, watchdog, dual-contactors and welded/stuck/open fault cases pass the frozen procedure
OPENNo-motion software boundary
approved target hash boots with all 25 torque bits, eight bus transmit paths, precharge request and action-ready output inactive; host logic is only precursor evidence
OPENTest environment
guarded area, fall restraint, fire response, thermal monitoring, observers and stop roles are physically ready
OPENInstrumentation and limits
calibration records, probes, shunts, current/voltage/temperature limits and abort criteria are frozen
OPENQualified release-to-test signoff
electrical, functional-safety, mechanical, controls and test owners sign the same frozen configuration
OPENPower-state ladder
Each state requires its own signed procedure. Advancing one state does not authorize the next. Motion is outside this ladder and remains prohibited.

Executable records
Every execution field is intentionally blank or NOT EXECUTED. An engineer must record real measurements and signatures against one frozen as-built configuration.
