Every Codex app-server start opens its SQLite databases (thread index, history projection, logs and others) from CODEX_SQLITE_HOME, which defaults to CODEX_HOME. On hosted placements CODEX_HOME sits in the state directory on NFS workspace storage, so a new Codex Session spent about 1.1 s just opening them.

The adapter now points CODEX_SQLITE_HOME at the Session's directory under the Runtime home on the compute's own disk. CODEX_HOME, with the rollouts, config and native history, stays in the state directory. The variable is added to the tool environment's skip list next to CODEX_HOME, and the Codex Runtime guide states the placement and its reason.

Measured on mx (microsandbox on NFS, MiniMax-M2.7, n=5 each), executor native_prepare for a new Codex Session:

	min–max	median
main (SQLite in CODEX_HOME on NFS)	1482–1744 ms	1501 ms
this branch	374–424 ms	387 ms

Why compute replacement loses nothing the Session needs:

• Codex looks up a thread the index lacks by searching the rollouts, rebuilds the history projection from the rollout, and reads dynamic tools from the rollout's session metadata.
• Goals keep their state only in SQLite. Disable Codex goals so no work outlives the Turn #876 disabled them.
• Memories are off by default and keep only extraction bookkeeping in SQLite.
• The queue is used only by the experimental thread/queue/* API, which the adapter does not call.

Live check on mx: a Codex Session remembered a code word. Then, inside its VM, its SQLite directory was emptied and the app-server killed. The next Turn started a new executor, which recreated the databases. It resumed the same rollout and answered with the code word. A plain suspend and resume keeps the VM's memory and disk, so it never reaches this path.

Verification on mx, from a checkout bundle of this tree: hosted acceptance 9/9 for Codex and 9/9 for Claude Code. Locally, go vet and go test pass for apps/daemon/internal/agent/codex and apps/daemon/internal/dispatch.
