🤖 should-fix 🟡 – ABORTED from UpdateActor now has a second cause, but the API guide still lists only the guard mismatch. Please add the in-progress case to the error line at docs/api-guide.md:663 (worker_selector "in any state" is still true, but not mid-operation). The ReportActorSnapshotState comment in ateapi.proto has the house wording: "Returns ABORTED while another operation is changing the Actor; retry."

Should this use leaseCtx instead of ctx? It might be worth just reassigning ctx = leaseCtx right after acquiring it to prevent mismatches like this."
UpdateActor relied only on the uid/version precondition, so it could interleave with a workflow that holds the actor lease. It now takes the lease like suspend, resume, revert, delete and tag do.

Reassign ctx to the lease context so later calls cannot use the parent ctx by mistake. Document that UpdateActor returns ABORTED while another operation is changing the actor.

Fixes #3129
UpdateActornow takes the actor lease, like suspend, resume, revert, delete and tag. A caller that races one of them gets Aborted and can retry.This is to prevent an actor's workerSelector or actorTemplate from getting updated during other operations such as suspend/resume.
AI use: AI-assisted with Claude Code, which drafted the code, test, and this description. I reviewed them.
