DESIGN.md §5.3. Reject DV Profile 5 and Profile 7, accept Profile 8.1, which
carries an HDR10 base layer and plays correctly on this setup.

Two things the naive version gets wrong:

  • "Blacklist Dolby Vision" would discard most good 4K releases. The existing
    library is almost entirely Profile 8.1.
  • Profile is knowable only from ffprobe. Pre-grab, a DV marker in a name
    means "claims DV" and its absence means nothing — so pre-grab this rule
    returns unknown, never pass.

Acceptance: unit tests per profile, and an integration test against the real
DV Profile 5 clip once the probe fixtures exist.

Depends on: #10

Two things the naive version gets wrong: - "Blacklist Dolby Vision" would discard most good 4K releases. The existing library is almost entirely Profile 8.1. - Profile is knowable only from `ffprobe`. Pre-grab, a `DV` marker in a name means "claims DV" and its absence means nothing — so pre-grab this rule returns unknown, never pass.
