US01-05 — Generate and Serve Managed Thumbnails

Epic: E01

As a reviewer, I want safe, correctly oriented previews so I can compare photos without
exposing arbitrary filesystem paths.

Acceptance criteria

  • Donor decode, orientation, resize, and HEIC behavior is reused where compatible.
  • Thumbnails are requested by asset ID, cached atomically, quota-managed, and
    invalidated when source identity changes.
  • Corrupt, oversized, missing, and unsupported inputs produce bounded typed errors.
  • Requests cannot escape configured roots or access excluded paths.

Automated tests

  • Golden tests assert orientation, dimensions, transparency handling, and cache keys.
  • Integration tests cover concurrent generation, corruption, invalidation, eviction,
    and path attacks.

Dependencies

  • US01-03
