I'll be landing this current series of julee branches tomorrow (more doctrine + crud generation) so I can properly fix the rba e2e tests. |

HttpPollerService accepts an optional header_factory callable that is invoked on every poll_endpoint() call. The returned headers are merged over any static headers in PollingConfig.connection_params, with factory headers taking precedence. This allows consumers to supply a fresh OAuth2 token on each poll without storing the token (or any callable) in PollingConfig, which Temporal serialises as JSON and cannot carry callables.

Summary
header_factory: Callable[[], Awaitable[dict[str, str]]] | Noneparameter toHttpPollerService.__init__()poll_endpoint()call, if a factory is set it is called and its headers are merged over any static headers inPollingConfig.connection_params(factory wins on conflict)PollingConfigor thePollerServiceprotocol — fully backwards compatibleMotivation
Auth headers embedded in
PollingConfigat setup time expire with the OAuth2 token (15–60 min), causing all subsequent polls to fail with 401. SincePollingConfigis serialised as JSON by Temporal, it cannot carry a callable — the factory lives in the activity (worker process) instead.Fixes #53
Test plan
