📝 Walkthrough

Walkthrough

Adds staff-only cohort filtering to the collection list. Cohort actions now link to filtered collections. The template shows the active cohort and can clear the filter. Browser coverage validates filtered, unfiltered, and non-staff behavior.

Changes

Cohort collection filtering

Layer / File(s)	Summary
Cohort collection entry isic/ingest/models/cohort.py, isic/ingest/templates/ingest/partials/cohort_actions.html	Adds a URL for cohort-derived collections and exposes it through the cohort actions menu.
Staff cohort filtering isic/core/views/collections.py	Resolves the numeric cohort parameter for staff users, filters collections through cohort images, and passes the selected cohort to the template.
Filtered list presentation and validation isic/core/templates/core/collection_list.html, isic/core/tests/test_collection_list_browser.py	Displays the active cohort, provides a link to show all collections, and tests staff and non-staff filtering behavior.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 592ed

Staff can view collections derived from a selected cohort and return to the full collection list, while non-staff requests ignore the cohort filter. The change has focused browser coverage and no remaining merge-blocking risk is identified.
