Remove the worker-side dwell timer now that delayed warmup engagement is scheduled durably by the consumer.
Keep DelaySeconds only for wire compatibility and run received warmup action batches immediately on the worker.
Wire warmup health webhooks in the consumer and log skipped warmup actions when a recipient mailbox has no assigned worker.
Run foldering and spam rescue immediately while keeping only low-stakes engagement signals behind the dwell delay.
Record warmup spam placements by recipient provider and surface provider breakdowns in the admin health summary.
Track warmup replies and use stable static conversation ids so warmup analytics can correlate content reliably.
Add warmup content generation and admin review surfaces, plus mailbox warmup appeal/status APIs.
Track warmup engagement and tampering signals so unsafe mailboxes can be handled by the warmup flow.
introduce two distinct warmup_spam_reports report types:
- spam_placement: provider classifier put the message in Junk on arrival
- user_complaint: recipient explicitly flagged the warmup message
detect placement at warmup arrival via the incoming message flags and
record it through a new WarmupService.RecordSpamPlacement. evaluate the
two signals independently in the health sweep — user complaints now
have their own watch/quarantine/block thresholds (0.5 / 1.5 / 3.0%)
since they are a stronger negative signal per event than placement.
persist conversation_theme on the warmup_token at send time, and look
it back up on reply so the body comes from the same topical bucket.
previously the reply picked a random conversation, so 'Re: time-
blocking question' could come back as a paragraph about travel.
mark_read, mark_important, remove_from_spam, and move_to_warmbly now run
on outlook and custom smtp/imap mailboxes, not just gmail. routes by
provider in the worker handler. carries source mailbox UIDValidity on
the action so the worker can SELECT the right folder before mutating.
