Badge resolver copied from the USB contract (SSO digits, 0<digits>BZ PayNo wrap) with names from the employees directory and the unknown-badge policy setting; deliberately copied rather than cross-imported so the contract test stays green. Restock and adjust write the ledger row and move the cached quantity in one commit - the single-commit invariant every write path must use. Adjust requires a reason and refuses to drive stock below zero. Detail page gains Restock/Adjust modals. Seven tests cover minting, the cache==ledger invariant, badge shapes, policy toggle, and auth.

"""Badge resolution for the printedparts plugin.
|
|
|
|
Same input contract as the USB plugin (deliberately copied, not imported -
|
|
cross-plugin imports break the shopdb.api-only contract):
|
|
|
|
- all digits -> an SSO typed or scanned directly
|
|
- 0<digits>BZ -> a physical badge wrapping a PayNo (keyboard-wedge
|
|
scanners emit this shape)
|
|
- anything else -> unresolvable
|
|
|
|
Names come from the employees plugin's self-hosted directory, looked up by
|
|
SSO. The directory carries no PayNo column, so PayNo badges resolve only when
|
|
the wrapped digits are themselves the SSO (true at sites whose badges encode
|
|
the SSO); otherwise they fall to the unknown-badge policy.
|
|
|
|
Policy (Setting printedparts_unknown_badge): 'deny' (default) rejects a badge
|
|
with no directory match; 'allow' records the SSO with an empty name.
