Sender: followers-only Create deliveries carry a signed
Collection-Synchronization header scoped to the authority of each inbox,
and the partial followers collection is served to authenticated instances
at /users/{username}/followers_synchronization.
Receiver: a signed Collection-Synchronization header whose digest differs
from our copy queues FollowersSyncPipeline, which fetches the partial
collection as the instance actor and reconciles followers, pending follow
requests and unknown follows.
Adds profiles.followers_url for the collectionId check.
Raise the mention regex local-part cap from 20 to 64 chars. The prior cap
silently dropped long usernames from autolinking/mentions, and for remote
handles it truncated the username and dropped the @domain, turning a remote
mention into a broken local one. Adds extensive lexer coverage.
For the rare cases where SQL must differ between MySQL and MariaDB,
add DatabaseDriver::isMysql()/isMariadb() and db_is_mysql()/db_is_mariadb()
alongside the existing grouped isMysqlMaria()/db_is_mysql_maria().
Laravel 11 exposes MariaDB as a dedicated 'mariadb' driver, so
config('database.default') === 'mysql' checks silently misclassified
MariaDB as the non-mysql (postgres) branch.
- Add App\Util\Database\DatabaseDriver with isMysqlLike()/isPgsql()
plus db_is_mysql_like()/db_is_pgsql() global helpers.
- Route all database.default driver checks through the helpers so
MySQL and MariaDB are treated as one group.
- Use '' (not null) for share/compose caption+rendered, valid whether
the column is nullable or NOT NULL (it is NOT NULL on MySQL/MariaDB).
- Guard pgsql strtolower() in registration against missing fields.
- Scope CustomEmoji::duplicateShortcodes to the grouped column for
Postgres GROUP BY validity.
- Remove stale Postgres guard in status:dedup; use havingRaw for
cross-driver HAVING.
Aligns with the app's dominant convention (171 static Str:: calls vs
24 Str::of() chains). Uses Str::afterLast() for the repeated
"segment after last slash" pattern, Str::matchAll() where a
Collection return is needed, and native explode()/substr() where a
plain array/string suffices.

Aligns with the app's dominant convention (413 now()/today() call
sites vs 12 Carbon::now()). Carbon::parse() calls are untouched since
they parse arbitrary date strings, not current-time access.
