Broadens the feature-flagged attachment affordance (same flag,
NEXT_PUBLIC_CLOSED_PO_ATTACHMENTS_ENABLED) from CLOSED-only to **any PO state
except REJECTED / CANCELLED**, for the same roles: the PO's own submitter plus
Accounts / Manager / SuperUser.
- lib/permissions.ts: canAddClosedPoAttachment → canAddPoAttachment(role,
status, { isSubmitter }); allows the submitter + ACCOUNTS/MANAGER/SUPERUSER
in any non-voided state. REJECTED/CANCELLED are always refused.
- uploadPoDocuments: voided POs are refused regardless of the flag; with the
flag on, uploads are restricted to those roles in any live state (the normal
create/receipt actors qualify, so those flows keep working); with the flag
off, the legacy behaviour stands (closed POs immutable).
- po-detail.tsx: the Attachments card now shows the uploader for any non-voided
state when permitted (not just CLOSED).
- Renamed ClosedPoAttachmentUploader → PoAttachmentUploader and the test file
to po-attachment-permissions.test.ts (flag-on matrix now covers live states +
rejected/cancelled refusal). Docs updated (feature-flags, .env.example,
CLAUDE.md).
Full unit + integration suites green; tsc clean.
