| ### 1. Stream name = capture session ID | ||
|
|
||
| Each capture session maps to a dedicated stream named by the session UUID. Streams are created automatically on first write (S2 does this via create-stream-on-append basin feature). This means: | ||
|
|
||
| - Replaying a session = reading one stream from seq 0 | ||
| - Concurrent sessions write to separate streams with no coordination |

do we persist capture session anywhere? mainly trying to understand how we'll do "reads" (e.g. after a browser session is destroyed or something)
| ### 3. Batching: 100ms linger / 50 records (S2 backend) | ||
|
|
||
| The S2 SDK batcher coalesces records before flushing to the network. Configuration: | ||
|
|
||
| ``` | ||
| Linger: 100ms | ||
| MaxRecords: 50 | ||
| ``` | ||
|
|
||
| These are independent of the ring buffer read loop — the writer appends one record per ring Read, and the batcher decides when to flush. |

may want to have these be env vars / configurable so we can externally control

I think this flow makes sense overall. I think it'd be helpful to have more clarity overall on:
- how enabling the s2 delivery ties into the existing APIs
- credentials for s2 within the vm

Overview
Adds a new design plan in
plans/s2-storage.mddescribing a proposed durable browser events storage sink (S2-backed) alongside existing file and SSE outputs, including component responsibilities, batching/record-size constraints, shutdown sequencing, and testing approach.Reviewed by Cursor Bugbot for commit 56d0a16.
