# Subscriptions are removed only when the task reaches the irreversible archived status. ``done`` is
# reversible in review/controller flows, so removing its subscription would silence a later reopen. We used
# to also unsub on any terminal event kind (gave_up / crashed / timed_out / blocked), but that silently
# dropped the user out of the loop whenever the dispatcher respawned the task: a worker that crashes, gets
# reclaimed, runs again, and crashes a second time would only notify on the first crash because the
# subscription was deleted after the first event. Same shape as the reblock-after-unblock cycle that PR
# #22941 fixed for `blocked`. Keeping the subscription alive until the task is archived lets the cursor
# (advanced atomically by claim_unseen_events_for_sub) handle dedup, and any retry-loop event reaches the
# user. Per-subscription send-failure counter. Adapter.send raising means the chat is dead (deleted, bot
# kicked, etc.) — after N consecutive send failures the sub is dropped so we don't spin against a dead chat
# every 5 seconds forever. A genuinely dead chat still drops, just ~60s later — a fine trade for an
# unattended gate where a false drop means silent work pileup.
