Keep disk state reads, sidecar stats and redis version lookup off the event loop Found with the blockbuster audit: - StateManagerDisk.load_state opened and unpickled the state file synchronously on every cache miss, once per substate. Move the read into a worker thread like the write already was, and drop the per-write states_directory.exists() by handling FileNotFoundError in the thread. - PrecompressedStaticFiles stat'd each sidecar candidate on the loop inside file_response, per accepted encoding per request. Starlette runs its own lookup in a thread; do the sidecar selection there too, from get_response, and finish the response (Vary/Content-Encoding, conditional check) after. - redis-py >= 7 resolves its own version through importlib.metadata for every new connection, scanning sys.path and reading METADATA on the loop. Create the client with the version pinned (driver_info on 7.x, lib_version before). Each change has a regression test that fails on the previous code.

Type the fenced save EVAL call for the minimum redis-py version Older redis-py stubs declare the EVAL arguments and reply as str, while the save passes bytes keys and payloads and reads back an int or nil.

Save state trees with one atomic lock-checked script instead of WATCH The redis client is created with retry_on_error=[RedisError], so when EXEC returned nil for a changed lock, redis-py reconnected and re-ran the transaction without the WATCH and the stale write landed anyway; the mock did not model that, only a real redis showed it. The save is now a single EVAL: the script compares the lock id, writes every touched state with its expiration, and returns the lock's PTTL, or nil without writing when the lock changed hands. That makes the check and write atomic on the server, safe under command retries, and one round trip instead of four (WATCH, GET, PTTL, EXEC). The mock emulates that script, and the WATCH-specific retry and tests go away with it. Also fall back to the full snapshot when a hydrate payload's hash list has a different length than the compiled states, instead of failing the event.

Retry the fenced redis save once when the connection drops while watching redis-py reports a connection error during WATCH as a WatchError, since the watch state is lost with the connection, and a lease refresh touching the lock key trips the watch as well. The fenced save now retries once on a fresh connection, which re-checks the lock before writing, and only a second WatchError discards the save as a lost lock. This surfaced in the lifespan integration test: the harness closes the redis pool on shutdown while a lifespan task's save is in flight, and the old unfenced path reconnected silently where the fenced one raised.

Read the lock TTL on the watching pipeline and name the boot protocol keys The TTL warning in the redis save now reads PTTL through the pipeline that holds WATCH, so the ownership check, the warning and the write use one connection instead of borrowing a second pooled connection while the first is held. The connect-packet and hydrate payload keys are named constants on CompileVars and used by the backend and the generated frontend template.

Fence state saves on the redis lock with WATCH/MULTI/EXEC The pipelined write of a state tree now runs as a transaction that watches the lock key: if the lock expired or changed hands between the ownership check and the write, EXEC aborts and the save raises LockExpiredError instead of overwriting a newer writer's state. The mocked redis models WATCH/MULTI/EXEC so the unit tests cover the aborted-save path.
