OptionalidOptionalpubsubThe host Durable Object's single pubsub identity — createHostPubSub() for the
default in-process emitter, or any PubSub the host built. init() is where a
DO's identity is established: it echoes the instance on InitResult, so every
consumer in the isolate takes THAT one rather than building its own (core
defaults a fresh emitter per createRun, and two such feeds never see each
other's events — see pubsub.ts).
OPT-IN: absent, InitResult.pubsub is undefined and no consumer has one to pass, so the host is byte-identical to before this seam existed (polling stays the fallback).
OptionalrequestServer-side requestContext source consulted on every start/resume — the grant-minting seam. See RequestContextProvider in runtime.ts.
OptionalresumeExplicit resume ledger (see RunnerRuntimeOptions.resumeLedger). When omitted, the runtime defaults to in-memory and the DO shell adopts a ctx.storage-backed ledger.
OptionaltableTable name prefix when init builds the D1 store.
Storage instance id when init builds the D1 store. Default: 'flowsafe'.
