An append-only storage ledger replaces deadlock-prone synchronous
counter updates and drift-prone async updates.
All content storage (card images, card/comment/board description embeds)
is tracked. Account exports (which expire) and avatars are not tracked.
Storage is accounted for by Account and Board. Both consume the same
event stream independently: no bubble-up storage bumps triggering
deadlocks due to lock sequencing. Each calculates its own total from
the underlying ledger with independent cursors and materialization.
* Storage::Entry: Append-only ledger recording attach/detach/transfer
events with delta bytes. Single event stream indexed for both
Account and Board cursor queries.
* Storage::Total: Polymorphic snapshot cache with cursor (last_entry_id)
tracking which entries have been materialized.
* Storage::Totaled concern: Provides bytes_used (fast snapshot) and
bytes_used_exact (snapshot + pending) query modes, plus
materialize_storage! to roll up pending entries.
* Storage::Tracked concern: For models owning attachments (Card,
Comment, Board). Provides board_for_storage_tracking for models
where board is determined differently (Board returns self).
Handles board transfers by recording transfer_out/transfer_in entries.
* Storage::AttachmentTracking: Hooks ActiveStorage::Attachment lifecycle
to record attach/detach entries. Handles ActionText::RichText embeds
by traversing to the actual model. Snapshots context in before_destroy
to handle cascading deletes where parent record may be gone by
after_destroy_commit.
* MaterializeJob: Rolls up pending entries into snapshot. Concurrency
limited per owner to prevent duplicate work.
* ReconcileJob: On-demand reconciliation against actual attachment
storage for support/debugging. Compares ledger total to real bytes
from card images, card embeds, comment embeds, and board embeds.
Usage:
* account.bytes_used / board.bytes_used: fast, slightly stale bytesize
* account.bytes_used_exact / board.bytes_used_exact: real-time bytesize
* Storage::Entry: audit trail for debugging and point-in-time queries
User are marked as verified after a join code is redeemed. The user is
redirected to Users::VerificationsController, either:
- after submitting a valid magic link code,
- or immediately after redeeming the join code (if they're already
authenticated with the correct identity)
Account owners are automatically verified when the account is
created (because they have already provided a magic link code at that
point).
This sets up for later commits that will backfill existing users and
require verification before sending notification emails.

- Adds a button in Account Settings where you can request a ZIP export of your
Fizzy data
- Export files are created in the background. When ready, a link to
download them is sent to the requester.
- Exports expire after 24 hours. And are limited to 10 per day.
