* Give the foreign key a backing index before dropping the unique
social_accounts.workspace_id carries a foreign key, and the composite
unique index is the only one covering it, as its leftmost prefix. MySQL
refuses to drop the sole index backing a foreign key (SQLSTATE[HY000]
1553), so both rehearsal suites failed in beforeEach and never ran a
single assertion on MySQL. Add a plain index on workspace_id first;
PostgreSQL has no such requirement and simply carries it.
This unmasks one assertion underneath that had never executed: the
automation graph comparison at DuplicateIdentityMigrationTest.php:419
depended on JSON object key order, which MySQL normalises on storage.
(cherry picked from commit 98a494bd2205e873321a18232f63b358ae259fdf)
* Compare JSON payloads without depending on key order
MySQL normalises JSON object keys (length, then lexicographic) on
storage, so an identity comparison against a literal asserts how the
driver chose to lay the object out rather than what it contains.
PostgreSQL preserves insertion order, which is why these passed there.
toEqual compares associative arrays recursively without regard to key
order. Applied to every assertion in this class, including the few that
pass today only because their keys already happen to match MySQL's
ordering.

* Match logged SQL without depending on identifier quoting
Four DB::listen predicates matched 'select * from "post_platforms"'.
PostgreSQL quotes identifiers with double quotes and MySQL with
backticks, so on MySQL the predicates never matched, the simulated
mid-run pause never fired, and the race these tests exist to cover went
unexercised while the tests still reported failures elsewhere.
Compare against the unquoted form via a small helper.

* Cast raw boolean reads in tests so they pass on MySQL
Three assertions read oauth_refresh_tokens.revoked through the query
builder rather than Eloquent, so no cast applies and the driver's native
representation leaks into the test: a real boolean on PostgreSQL, 1 on
MySQL. Cast explicitly at the call site.
(cherry picked from commit 2911c5c48cf65d24a34a41e667335c40005839a7)
* Use a scheduling date inside MySQL's TIMESTAMP range
MySQL TIMESTAMP columns end at 2038-01-19, so the 2099 sentinel these
tests used is rejected outright with SQLSTATE[22007]. 2037-12-31 still
reads as a far-future schedule and works on both engines.
(cherry picked from commit bde33eb239cdbd3a5567d4c21e1d85302913cdd7)
* Remove the duplicate-identity migration scenario test
The suite rebuilt a pre-migration schema by dropping the unique index in
beforeEach and re-running the migration by hand, exercising a database
state the application never runs in.
* Fix the MySQL rollback path and run CI on both engines
The migration's down() dropped a unique whose leftmost prefix is an FK
column, which MySQL refuses when nothing else backs the constraint
(SQLSTATE 1553). It now creates a standalone index first, so
migrate:rollback works on MySQL and stays a no-op change for PostgreSQL.
up() is untouched: every database already migrated keeps its schema.
The rehearsal test calls that down() instead of hand-rolling the drop,
so it exercises the real rollback rather than an imitation of it.
Matches logged SQL through the connection's query grammar rather than
stripping quote characters, and adds a MySQL leg to the backend CI job.
* Use a readiness check both database images can run
mysql:8.4 installs mysql-community-server-minimal, which ships neither
mysqladmin nor the mysql client, so a mysqladmin health command never
succeeds and the service never reports healthy. Both images run their
init phase without networking, so an open port is the point either
engine starts accepting connections - one check covers both, and the
per-engine matrix key goes away.
* Use each engine's own readiness tool
pg_isready and mysqladmin ping are what the respective images ship for
this, and the mysql image's entrypoint invokes mysqladmin itself, so it
is present. Keeps 20 retries, which MySQL needs to finish initialising.
* State the two-engine ceiling as a rule, not a test detail
The 2038 TIMESTAMP limit binds anything written to the column, not just
the sentinel dates in fixtures, and the same reasoning generalises: what
the app supports is the intersection of both engines.
* Let the release image connect to MySQL
The published image installed only pdo_pgsql, so DB_CONNECTION=mysql
failed with "could not find driver" before any query ran - the app
supports MySQL but the image people actually deploy could not reach it.
mysql-client mirrors the postgresql-client already present, for
artisan db and dumps.
* Keep "backend" a single required status check
Matrixing the job split its check in two, so the "backend" context the
branch protection requires was never reported and every PR sat waiting
on it. The matrix is now "tests" and a small "backend" job gates on it,
which keeps the required check stable however many engines the matrix
grows to - and leaves the open PRs mergeable without a rebase.
