Supersedes #160 and #163, the two halves of the SDK's jump to spec version 6 that Renovate split into separate PRs. Neither passes alone: #163 (
workflow→ beta.42) makes the runtime demand a spec-6 World while ours still declared 5 (hard startup gate → 500s), and #160 (@workflow/world→ beta.27) advancesSPEC_VERSION_CURRENTto 6 while the runtime still stamps runs at 5, so the cbor test asserts5 !== 6. This bumps both together and implements what spec 6 actually requires.Spec 6 is "slot identity": an event id must be slot-numbered —
evnt_followed by the event's dense, 1-based position in its run's log, zero-padded to 26 characters. The runtime callsrequireEventSloton every event id it loads and fails the run if it cannot read a slot, and it enforces density (no holes) by default. Our service previously exposedeventId = String(row.id)(the Postgres serial), which the runtime rejects with "Event id is not slot-numbered".
