fix(server): t3 thread and t3 project no longer create a database when statev2.sqlite is missing - #27212
t3 thread … and t3 project add|rename|remove build EnvironmentAuth.layerRuntime before they check anything. That layer includes SqlitePersistence.layerConfig, so while userdata/statev2.sqlite is missing (moved aside during a replace or restore, or a fresh base dir), any CLI call creates and fully migrates a new empty database where the real one belongs.
Reproduced on main dd14848 with t3 serve --base-dir B, then statev2.sqlite* moved aside:
t3 thread list --base-dir B left a 50-table, 0-project statev2.sqlite and minted its MCP session into it. The live server then answered 401.
t3 project add <dir> --base-dir B also created one, then exited 78 with a stack trace from acquireServerOwnership.
With no server registered, t3 thread list printed "No running T3 Code server uses B" and still created and migrated a database (on a never-created base dir, the whole data dir).
Change
cli/config.ts adds requireServerDatabase(dbPath): if the file is missing, it fails with ServerDatabaseMissingError ("T3 Code's database is not at . The server may be restarting."), printed as one line.
t3 thread reads server-runtime.json before it provides the auth/storage layer. With no server registered it fails with the existing ThreadServerNotRunningError without opening a database. With a server registered it runs the database check first.
t3 project reads the runtime state once, up front. With a server registered it runs the same check, then passes the origin to the live-mode probe. With no server registered, the offline path is unchanged and still creates a database on a fresh install.
The existing live-server project test now seeds a database before it registers the server. It used to depend on the CLI creating one.
Sqlite.ts and EnvironmentAuth.ts are untouched, so this does not conflict with the CLI storage-layer rewrite in #26763.
New tests, which fail on main because statev2.sqlite gets created and pass here:
src/cli/thread.test.ts › thread CLI state › does not create a database when a server is registered and statev2.sqlite is missing
src/cli/thread.test.ts › thread CLI state › does not create a database when a server is not registered and statev2.sqlite is missing
src/cli/project.test.ts › does not create a database behind a registered server when statev2.sqlite is missing
vp test run src/cli/thread.test.ts src/cli/project.test.ts: 17/17. vp run check:changed: format, lint, knip, typecheck (3 packages) and tests (33) all pass.
Runtime transcript from the real CLI (node apps/server/src/bin.ts) against a scratch server, same driver on each side:
Not checked: Windows and macOS (the check is a portable fs.exists). A file removed between the check and the open can still be created; this fix covers the already-missing case the issue reports.

…n statev2.sqlite is missing
Both commands built the auth layer, which opens and migrates statev2.sqlite,
before reading server-runtime.json. With the database moved aside, they left
an empty migrated database behind the live server. With no server registered,
`t3 thread` created a whole data dir only to report that no server runs.
`t3 thread` now reads the runtime state first and fails before building any
storage layer. When a server is registered and the database is missing, both
commands fail with "T3 Code's database is not at <path>. The server may be
restarting." and create nothing. Offline `t3 project` with no server
registered still creates the database on a fresh install.

Macroscope's review found this PR approvable — Thread and registered-server project commands now stop when the server database is missing, before database initialization or directory cleanup. Offline project setup remains available, and the supplied concern about preflight ordering is addressed.

Walkthrough
Project and thread CLI commands can defer directory setup during auth configuration. When persisted server runtime state exists, they require the server database before preparing directories and continuing. Project live-mode detection receives the persisted server origin.
Changes: CLI database guard
Layer / File(s)
Summary
Database validation and setup apps/server/src/cli/config.ts
Adds ServerDatabaseMissingError and requireServerDatabase. Directory preparation moves to prepareServerDirectories, and resolveServerConfig can defer setup.
The project mutation path checks for the database when persisted server runtime state exists, prepares directories, and passes the persisted origin to live-mode detection. Tests cover missing-database behavior and update database setup for project command cases.
The thread command checks runtime state and validates the database before session setup. Tests verify that a missing database remains absent and an expired upload remains present.
pingdotgg/t3code#26696: Both concern CLI access to the running server’s database. This change handles the missing-database case; the issue describes pending migrations.

The scope section does not include an explicit maintainer approval comment, but the description is otherwise complete and focused.
Full details: Linked Issues check
Explanation
Issue #27120 requires t3 thread and registered-server t3 project commands to fail before opening a missing statev2.sqlite. The current diff defers setup, reads server-runtime.json, checks config.dbPath with requireServerDatabase, and only then prepares directories and auth layers. The thread path fails with ThreadServerNotRunningError before setup when no server is registered. The project path preserves offline setup and applies the database check only when runtime state exists. Tests cover the registered thread path, the registered project path, and the preserved offline behavior.

Run the database preflight before directory setup.
resolveCliAuthConfig can create state directories and delete expired pending uploads before requireServerDatabase runs. The sweep removes pending files older than 24 hours and partial uploads older than one hour. This affects both project and thread commands.
Separate read-only path resolution from setup. Run the runtime-state and database checks first. Preserve offline t3 project behavior by performing setup after the no-server decision.

thread.test.ts now mocks EnvironmentAuth on main, so the CLI can no
longer create a database there; the thread case asserts the guard's
typed error instead, and main's start test registers a database file.

…the database check passes
Config resolution created directories, tightened userdata permissions and
swept expired uploads before the missing-database guard ran. Both commands
now resolve paths with setup deferred, run the guard, and only then prepare
the directories.

A registered server always has statev2.sqlite, and the project CLI now
refuses to run without it, so these fixtures create one.
AI-assisted; verified with the tests and tools listed above.
On both commits, run a real server on fresh disposable data, move SQLite and its sidecars aside while it stays running, then invoke thread list. Repeat independently for project add. Finally check thread list on a never-created directory and fresh offline project add. Environment: Linux, real Node CLI/server, isolated loopback ports, synthetic workspace, seeding disabled.
Base recreated statev2.sqlite for both commands. Head reported its absence and created no files. Thread list initialized the never-created directory only on base. Fresh offline project add succeeded and created its database on both commits. Servers remained running throughout each missing-database check.
Qualification: the running server's trace log changed during the head project check; every other existing file hash was unchanged, and no files were created. AI-assisted; verified with the tests and tools listed above.
Not shown:
Absolute absence of all data-directory writes during the head project command: userdata/logs/server.trace.ndjson changed while the server remained running, so the comparison cannot attribute that write. No replacement database or other files were created; all other existing file hashes stayed unchanged.
