unitscan's rare alert was reported as silent. The binding and the loose-file read were both
already right: kira was built without the `ogg` container and `vorbis` codec features, so
`sfx_from_bytes` returned an error for every Vorbis file and `sound/ui.rs` logged it at `debug!`.
A silent alert with nothing in the log to say why.
It is not one horn. **75 `.ogg` files ship with the installed addons** — DoiteAuras 57, BigWigs
11, unitscan 3, HCWarn 2, TWThreat and Cleanup one each — so every alert any of them raises by
`PlaySoundFile` was dead, HCWarn's hardcore death warnings included. AI_VoiceOver ships `.mp3`
and always played, which is exactly what made this look like an addon-specific fault rather than
a missing decoder.
Stock 1.12 plays wav and mp3 only. The deviation is from 1.12 and toward the client the player
actually runs: these are Turtle/OctoWoW addons shipping ogg because that client plays it.
`docs/ADDON_COMPAT.md` carries the row.
The test decodes a real `.ogg` out of the player's own addon folder and skips when there is none,
the same gate the chain-backed tests use for a WoW install — rather than carrying someone else's
audio into the tree as a fixture.
