A thumbnail is the one derived artefact worth sending over the wire: it costs a range fetch plus a decode to produce and is identical for every client looking at the same file. A second device that downloads a shard gets a full grid without fetching a byte of RAW. Sharded at 25 MB, filled sequentially. The cap is about sync granularity, not SQLite's limits — one growing database means every client re-downloads it whenever a single thumbnail is added, whereas with sequential fill only the newest shard is ever dirty and sealed shards are safe to cache forever. Stored JPEG-encoded rather than as raw RGBA: a 256px RGBA buffer is ~256 KB against ~20 KB encoded, and that 13x is transfer cost on every client. Keyed on Nextcloud's oc:fileid, stable across server-side rename and move. Assisted-by: LLM
