feat: step 7's migration, with an index on spaceId
The first migration since the initial one, created with the CLI (serverpod create-migration --tag studysets), since no MCP bridge was set up yet. On the server it is one transaction that only adds: gen_random_uuid_v7(), the studyset table, the sync engine's tables (spaces, their members and nodes, the CRDT bookkeeping, the log of integrity violations) with their foreign keys, and, from Serverpod v4.0.3, the auth module's profile image foreign key re-created as DEFERRABLE INITIALLY DEFERRED, so that dumps restore. The server tests apply it to their Postgres.
studyset gets an index on spaceId: deleting a space cascades into every synced table, and Postgres doesn't index foreign keys by itself, so account deletion and pruning would otherwise read whole tables. AGENTS.md makes it the rule for every synced table.
The client migration creates each device's SQLite schema. The generator builds it from the whole definition, so it also contains the server's own tables; only the synced tables and the bookkeeping ever hold data on a device.

feat(server): cards and their append-only revisions, synced
Card belongs to a studyset and carries only its position, a fractional index (last writer wins), so cards can be reordered and bulk imports keep their order. Its content lives in CardRevision rows, which are never updated except to blank them (ADR 0001, rule 2): parents lists the revisions a revision replaces (decided: a list, so a revision with two parents resolves a conflict), authorId the writer, reportId the report it answers once reports exist, and the envelope holds the content. Deciding the list of parents and the position now matters: changing a synced table later locks out older app versions.
The migration (created by CLI) only adds: the two tables, an index on spaceId for each (space deletion cascades into them), one for a studyset's cards in order and one for a card's revisions, and the foreign keys, from the space with ON DELETE CASCADE and from the studyset and the card with ON DELETE CASCADE, DEFERRABLE INITIALLY DEFERRED, since synced rows can arrive in any order. The client migration creates the same tables on each device.

feat(server): tree, tags, review modes, settings and assets (ADR 0004)
The schema of the features planned for the first release, as one migration: every
migration of a synced table locks older app versions out of syncing (ADR 0002, rule 3),
which costs nothing before that release. New card types need no migration; they are the
next version of the revision payload.
- studyset: `parent` (the tree; cycles and orphans show at the top level) and `position`
among siblings (fractional index; existing studysets at 'a0').
- tag (its name in the payload) and card_tag, one row per assignment, so concurrent
adds and removes merge.
- review_log.mode: review, reverse (a schedule of its own) or cram (never moves a
schedule); existing reviews are 'review'.
- person_settings: study goals now, preferences later; random ids, since an id derived
from the person could be claimed by someone else and break the owner's sync.
- asset: a file's hash, type, size and name; the file goes into Serverpod's private
cloud storage, served through an owner-checked endpoint (to come).
Migration 20260930211154224-tree-tags-assets only adds: four tables with their space
indexes and foreign keys, three columns with defaults. On devices SQLite rebuilds
studyset and review_log to add foreign keys, which is safe only with foreign keys off,
as Serverpod's runner does; a new test replays every client migration on a database
with a row in each of our synced tables and checks that none is lost (with foreign keys
on, it fails as it should).
