The problem this fixes
Most CMSes have a writer/reader split for scale: writes go to one process, reads to another. The split breaks read-after-write — your "create then read" sequence gets the cached pre-write snapshot.
Common workarounds: poll, retry with backoff, "wait 200ms then read", or just give up and treat the API as eventually consistent.
How StaticOwl handles it
The engine issues a write ticket on every mutation response. The SDK stores that ticket and auto-injects it as a Graph-Write-Ticket header on subsequent reads. The router routes ticket-carrying reads to the writer (or to a reader that's caught up to the ticket's seq). Cache misses fall back transparently.
What you can rely on
- Same client, same process: read-after-write works. No polling. No retry loops.
- Across processes: the SDK can serialize/deserialize tickets. Pass them through your job queue and downstream readers see your writes.
- Across browser tabs: the admin UI ships RAW carriage end-to-end so navigating after a save shows the saved state.
What this enables
- AI assistant with tool-use that reads back its own writes without race conditions
- MCP servers that compose multi-step operations without "wait then retry"
- Bulk imports that write 10K records and immediately query them
Trade-off
Routing some reads to the writer adds latency for the duration of the ticket TTL (5s default). For most workloads this is invisible; for very high-read-volume scenarios you can disable RAW per-client.
