Function: usageDedupeKey()
usageDedupeKey(
event):string
Defined in: backend/src/usage/index.ts:69
The key an append is idempotent on: (runId, stepId) when a step is known, else the event id.
Lives here rather than in an adapter so every adapter dedupes identically by construction. The
reference adapter owned a private copy of this, which meant "both adapters agree" was a
coincidence — the same situation DEFAULT_SESSION_STATE_MAX_BYTES was in before #97 moved it to
the port. A recovered run re-recording a step it already logged must be a no-op in every adapter,
because the alternative is double-counting real money.
Parameters
event
Pick<UsageEvent, "id" | "runId"> & object
Returns
string
