"""One-shot migration: split a per-theme audio.json into the subscription-
|
||
|
|
pattern triple used everywhere else in the codebase.
|
||
|
|
|
||
|
|
Before:
|
||
|
|
public/games/<theme>/data/audio.json
|
||
|
|
{schema_version, sfx: {...}, music: {tracks: [...], victory_pool, defeat_pool,
|
||
|
|
default_track_id, crossfade_seconds}}
|
||
|
|
|
||
|
|
After:
|
||
|
|
public/resources/audio/library.json # shared catalogue
|
||
|
|
{schema_version, sfx: {...}, music: {tracks: [...]}}
|
||
|
|
public/games/<theme>/data/audio/manifest.json # subscription
|
||
|
|
{source: "resources/audio", includes: true, overrides: {}}
|
||
|
|
public/games/<theme>/data/audio/pools.json # per-game routing
|
||
|
|
{default_track_id, crossfade_seconds, victory_pool, defeat_pool}
|
||
|
|
|
||
|
|
The migration assumes the current single audio.json IS the only library —
|
||
|
|
i.e. all entries are subscribed by Game 1. Future games author their own
|
||
|
|
manifest.json with `includes: [whitelist]` or overrides.
