+"""Add ticket_watchers and time_entries tables
+
+Revision ID: 005_add_watchers_and_time_entries
+Revises: 004_widen_system_setting_value
+Create Date: 2026-05-22
+
+Rationale
+---------
+Two new features require dedicated tables:
+
+ticket_watchers — lets any logged-in user subscribe to ticket updates beyond
+the ticket creator and assignee.  One row per (ticket, user) pair; cascade
+deletes with the ticket.
+
+time_entries — lets IT staff log minutes worked on a ticket, with an optional
+short note.  Cascade deletes with the ticket.
+
+Apply
+-----
+    flask db upgrade
+
+Rollback

+    flask db downgrade
