Gravelight Gannet Bonded Latch Service Issue

Gravelight Gannet is the service-depot latch issued for tool cribs and hazardous-parts lockers. A broad cobalt-steel tongue slides behind two replaceable strike blocks, all wrapped in a grit-shedding alloy shell with controls large enough for pressure gloves. The frame needs six through-bolts and a squared opening; fit it crooked and the tongue chews its own bushings, a failure visible through the yellow inspection window. Access uses crew badges plus a rotating foreman code for restricted shifts. The latch writes 6,000 entries to a removable audit wafer and embosses a tiny date mark on a foil service ribbon whenever the cover opens. Welding arcs and ungrounded motors can cause false badge denials, but not false openings. Ship power runs it normally; a slab cell provides ten days of monitoring and sixty cycles. Depot rules treat an opened service cover as a controlled-parts discrepancy. Even an innocent repair can freeze the whole crib until inventory is counted—usually at the least charming hour available.
