The shopfloor feed kept every ended notification up for a hardcoded 30 minutes, flagged resolved. A card with an 8:00 end time was still on the board at 8:29, which reads as an expiry that did not work - and in the carousel, grid and banner sections it read that way with no visual sign at all, since only the standard cards render the resolved state. The tail is now notificationtypes.gracewindowminutes, set per type on the Notification Types page and defaulting to 0, so an end time means what it says. A type whose cards are worth acknowledging after they clear - an incident, say - opts into a tail, and only that type's cards get one. The feed widens its query to the largest configured tail and then holds each row to its own type's window. That keeps one portable query rather than a per-type interval expression in SQL, and with every type at 0 it collapses to "still showing". Also fixes resolved serializing as null rather than false for a card with no end time, which the and-chain produced.

"""Per-plugin Alembic migration-chain guard tests.
|
|
|
|
Ownership cutover (ADR-008): the core Alembic chain created every table that
|
|
exists through its head (`7d16_directoryemployees`), including the plugin
|
|
tables. From that point on, each bundled plugin that owns tables carries its
|
|
own chain under `plugins/<name>/migrations/`. The `0001` migration in each
|
|
chain is a stamp-only no-op anchor: the core chain already built the tables, so
|
|
there is nothing to create; the anchor just gives the plugin chain a base that
|
|
`flask plugin upgrade-all` stamps into `alembic_version_<plugin>`.
|
|
|
|
These tests pin that contract:
|
|
* PLUGIN_TABLE_OWNERS stays in sync with what the models declare.
|
|
* Every plugin that owns tables has a valid single-head chain.
|
|
* The anchor migrations are genuine no-ops.
|
|
* `flask plugin upgrade-all` runs clean on a fresh DB and is idempotent.
