The route cap bounded project-assigned CLI rows PER PROJECT at 200, which
is not a bound on the payload: 200 rows times N projects grows with the
project count. The review's own reproduction still held — 1,000 assigned
conversations spread over 5 projects returned all 1,000, because no
project exceeded its own 200 (#6659 review finding 1). Imported WebUI
sidecars from all_sessions() never pass through a state.db cap, so this
merged pass is the only place that can bound them.
Give each project an EQUAL share of a global CLI_PROJECT_ASSIGNED_SCAN_CEILING
(ceiling // projects, never below 1) once enough projects exist to make that
share tighter than the per-project cap. Same shape as the model-side share of
PROJECT_ASSIGNED_CLI_SCAN_CEILING, and for the same reason a flat global cap
is unusable here: it would leave every project past it permanently
unreachable on each rebuild (greptile P1). Profiles with a few projects keep
the full 200, so the common case is unchanged.
The ceiling is duplicated as a literal because api.models is imported below
this cap in api/routes.py; a test pins the two equal, mirroring
test_background_source_exclusion_literal_matches_the_constant.
