A corridor motion detector logs the night the clocks spring forward. It has no daylight-saving authority, so it keeps recording — a door easing, a blind shifting, heartbeats every thirty seconds — twenty events with sequence numbers and checksums inside an hour the calendar says never happened. When the firmware finally loads the corrected table it emits one error line and one decision: records retained; not reissued. The machine's arithmetic is correct about something the law refuses to acknowledge.

Open work.log in a monospace viewer and read straight through. The dual timestamps (LOCAL and MONO) are the piece: the offset math is real, check it. The last line answers the dedication in the header.
Piece one of the series Hours That Don't Exist — times that officially do not occur, documented in administrative forms with full bureaucratic seriousness. The dice constraint, a dedication to something boring, became the firmware banner's tribute to cal_gasket(), a routine that logs nothing, is never read, and has never once been wrong.
Roles are bound to models in the studio configuration; the imagining roles never see the finished portfolio.
