"""Feedback module — feature requests / feedback / bug reports from every user.

Sits OUTSIDE the Dashboards/Workflows nav groups (its own sidebar entry). Submissions accumulate
in the platform's writable HF Dataset store (core/store.py, key 'feedback') so they survive
restarts and are shared across users/instances. The record shape is deliberately structured so an
AI staging pass can later triage items into the build workflow (type/module/importance/status +
free-text details). No Odoo involvement at all — this module never touches ERP data.

Statuses: New (just submitted) -> Staged (AI/owner queued it for a build cycle) -> Planned ->
Done | Declined. Triage is admin-only; submitting is open to every signed-in user.
