CHECKPOINT_SAVED.md

# Schematic-only revision 0.4.55

Based on the preserved, published 0.4.54 board. The current acceptance record
is `reports/clean-schematic-acceptance.json`; its circuit hash identifies the
validated build. Publication is verified separately in the publication receipt.

All 7,424 electrical/hardware records remain unchanged: parts, nets, PCB,
copper, drills, paste, CAD and motor assembly. Firmware is unchanged.
57 tests pass, with zero native errors, shorts or schematic-style issues and
no added warnings. The 151 inherited warnings and fabrication-qualification
gaps remain; see `verification.json`.

The local checkpoint helper writes an archive and independently verifies every
restored file. The checkpoint directory/receipt is recorded in the workspace's
`ACTIVE_BOARD.md`; the earlier 0.4.54 checkpoint is also retained for rollback.
