# Source information

All47 CC0 natives retain exact bytes and original filenames. Per-file records in
provenance/ bind creator, source page, archive/member and native hashes. Labels
follow creator filenames, descriptions and metadata, not independent listening.
No auditory-quality, isolation, realism, event-count or seamless-loop certificate
is made. Source pages and raw QA logs are private evidence, not public payload.

Computer noise, Space engine, Force field and Small laser are synthetic game
effects whose native comments identify GameSynth by Tsugi; Kenney distributes
them. Glass breaking is by Pixel-boy / Sparklin Labs; MedicineStorm submitted
the OGA mirror and is not substituted as creator. Original notices are preserved.
Matching workshop names, including scrape4, are WAV chapter titles, not global
TITLE fields. Card-pack opening retains stream TITLE openPackage2 and the
original MP3GAIN tags; no gain has been applied. The two synthetic footsteps
and Interface scroll also retain native GameSynth by Tsugi comments. Creature
roar, Bulls and Desert ambience retain their game-origin labels, not wildlife
or field-recording certification. Gong-like cue does not certify an instrument.
Glass breaking retains both container0.591451s and prior decoded0.588549s in its
source record; the difference is not a new trim or claimed decode failure.
Short whoosh and the two new footsteps similarly retain separate container and
prior-decoded durations, about2.902–2.903ms apart. Original levels and quiet spans
remain unchanged; small sample headroom is not an audible clipping diagnosis.

All49 legacy records, original permission, MP3/WAV URLs and music grouping remain
exact. The complete ZIP contains their existing MP3s; no legacy source is regenerated.
