-- Servatrice db migration from version 40 to version 41
|
|
|
|
-- Deck collection sync + versioning.
|
|
--
|
|
-- 1. Stable per-deck identity and change detection for two-way sync:
|
|
-- guid links a local file to its server row across renames, hash detects
|
|
-- content changes without downloading, last_modified drives newest-wins
|
|
-- default and conflict highlighting, deleted implements tombstones so a
|
|
-- delete on one device does not resurrect from the other.
|
|
-- 2. Limited per-deck version history: every hash-changing upload inserts a
|
|
-- row; the server prunes beyond the configured retention (default 20).
