When a directory is created, the watcher starts watching it, but files written into it before the watch is added (e.g. `mkdir -p dir && echo > dir/file`) produced no events. Scripts, AI agents and git checkouts do this all the time, so those changes were silently missed until something else triggered a reload. Record a CREATED event for each file found in the new directory.
Both the Go and TS parsers now tell the user to create the directory and add a migration file, which is the usual next step when declaring a new database.
Databases are only created and migrated when the SQL cluster starts, so adding a database or migration while `encore run` is running isn't applied. Reloads still printed "Reloaded successfully." and requests then failed. After a reload, compare the app's databases and migrations with the cluster and list what needs a restart. The list is only printed in full when it changes, so several reloads while setting up a database don't repeat it. Databases that a reload does set up (the app's first database, which starts the cluster) are now reported too, instead of happening silently.
WalkthroughThe changes add database migration status reporting to reload messages, record existing files when the watcher encounters a new directory, and expand missing migration-directory errors in both SQL parsers. ChangesDatabase reload status

441-441: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winUse a source-specific migration example.
The missing-directory check runs before the parser selects a migration source. This message therefore also applies to Drizzle, DrizzleV1, and Prisma, which use different file layouts. Following the
1_init.up.sqlexample can cause a parse error or leave the parser with no discovered migrations. Select the example by source, or use format-neutral guidance.🤖 Prompt for AI Agents

With no applied versions, a sequential migration numbered 0 (Drizzle's first migration) was treated as applied. And when a database's applied migrations couldn't be listed, the reload reported success and forgot the previously reported changes; it now says the database couldn't be checked.
Populate the directory elsewhere and move it into the watched root, so the file can only be reported by the directory scan, not by its own event.

Problem
Adding a database or a migration while
encore runis running isn't applied: databases are only created and migrated when the SQL cluster starts. But the reload still printedReloaded successfully., and requests to the new database then hung and returned 500 until you restarted. Nothing told you a restart was needed.What this changes
Applying stays explicit (restart
encore run), but you're now told when that's needed and what's pending. A typical flow is several reloads in a row (declare the db, add the folder, add a migration, edit it), so the output is state-based rather than per reload: the full list is printed when it changes, and a one-line reminder otherwise.Pending changes, then a reload with nothing new, then a second database added:
The app's first database is applied on reload (adding it starts the cluster, which creates and migrates it). That used to happen silently; it's now reported:
Declaring a database before its migrations directory exists now says what to do next, in both parsers:
Watcher race fix
While testing,
mkdir -p hello/migrations && echo ... > hello/migrations/1_init.up.sqldidn't trigger a reload at all. When a directory is created, the watcher starts watching it, but files written into it before the watch is added produce no events. This affects all apps (Go and TS) and any file, not just migrations: scripts, AI agents and git checkouts create directories and files this way all the time. The watcher now records aCREATEDevent for each file found in a newly created directory.Implementation
sqldb.PendingMigrations: which migrations aren't applied, for sequential (latest version only) and non-sequential migrations; dirty versions count as not applied.ResourceManager.DBChanges: compares the app metadata with the running cluster; databases not in the cluster are new.Run.reloadedMessage: formats the result, remembers the last printed list, and tracks which databases this run has set up so it can report ones created during a reload.watcher.recordExistingFiles: the race fix above.Testing
