US07-03 — Harden Media and Metadata Edge Cases

Epic: E07

As a user, I want unusual or damaged media handled safely so one file cannot corrupt
metadata, exhaust resources, or stop the library workflow.

Acceptance criteria

  • Supported format/orientation/profile combinations have bounded decode behavior.
  • Corrupt, truncated, huge-dimension, unsupported, and malformed-metadata files become
    precise item errors without worker failure.
  • EXIF checkpoints preserve user fields and previous-stage fields, read back owned
    fields, and mark conflicts divergent rather than silently repairing them.
  • Cache regeneration/invalidation and temporary-file cleanup are safe and scoped.

Automated tests

  • Extended golden corpus covers all declared format, orientation, corruption, and EXIF
    cases with memory/time bounds and before/after metadata snapshots.

Dependencies
