My Work previously materialized all matching rows and repeated a parent lookup for every row. The new regression fixture measured 601 parent queries for 601 tasks on two parents.

Scan tasks, assignments and mentions in primary-key pages of at most 200 rows, retaining only the ten display tasks. Preserve exact caller-visible counts, due-date ordering and current parent authorization. Cache visibility only within each page; a starting maximum ID prevents new inserts from extending a scan indefinitely.

Validation: full Maven verify passes 193 tests with zero failures/errors/skips, packaging and coverage. New query-budget tests cover repeated parents, cross-page assignment/mention counts, hidden records, other users, undelivered mentions and permission changes between requests. Existing sharing/work tests pass.

Related QRun-IO/qqq#1291; stacked on attachment PR45 to preserve the verified candidate baseline. Draft: PostgreSQL query budgets, browser/N-node sustained load and failure qualification remain outstanding. This bounds row retention, not total work independently of matching data size; unique-parent authorization remains linear. See docs/MY-WORK-QUERY-BOUNDS.md.
