Check resolveTEEVerifierAddress first so that the streamer is not left running after an error.

Use LocalSafeL2 instead of SafeL2 so that Channel Manager and Streamer reset on the same heads.

Roll back running state on Espresso setup failure so that a failed start does not block later start attempts.

Anchor the streamer at the local-safe head during construction so that startup does not depend on the L2 endpoint serving the historical origin height.

philippecamacho

claude
committed
b48d811
Floor every streamer anchor and sync comparison at the caffeination point so that the Espresso batcher never treats pre-activation blocks as its own.

philippecamacho
and
claude
committed
696aeb9
Bound every raw RPC read on the Espresso startup path with the network timeout so that a stalled endpoint cannot hang StartBatchSubmitting while it holds the start mutex.

claude

Re-anchor the streamer instead of queueing batches at or below the local-safe head so that already-derived blocks are not resubmitted after a restart.

philippecamacho
and
claude
committed
790b12e
Gate startup on the caffeination point being local-safe instead of anchoring on a cached unsafe floor block, whose reorg could permanently wedge fork selection.

philippecamacho
and

Retry on zeroed sync-status fields in nextBlockRange so a transient zero LocalSafeL2 cannot floor the queue at genesis and re-enqueue derived history.

philippecamacho
and
claude
committed
6c02fe6
Skip the drain tick when the sync status is out of sync so a zeroed LocalSafeL2 cannot disable the stale-batch re-anchor floor and republish derived blocks.

philippecamacho
and
claude
committed
09485ba
Fetch the streamer re-anchor target before clearing state so a transient sync-status failure cannot empty the channel manager while leaving the streamer at its old cursor.
