Wires the delivery_worker's retry loop on top of the erlang:send_after / cancel_timer primitives just landed on loops/erlang (3709460d,98b0104c,779e53b2— cherry-picked here since origin/architecture hasn't caught up yet). Surface: - new :timers [{Cid, Ref}] state field tracks live timer refs - handle_call(flush): drain (existing semantics) + arm_retry_timer per retried Cid (computes backoff slot from the now-bumped attempt count, sets next_retry_at, send_after self-cast). Reply shape unchanged. - handle_info({retry, Cid}, S): redrives that one Cid through deliver_one_pure. Success → record_success_pure + clear pending. Failure → schedule_retry_for (which bumps attempts, dead-letters on slot 6, or arms next slot). - cancel_timer_for/2 before arming a new timer so stale timers don't keep the scheduler's run loop alive after the work is done. - state_srv/1 + timer_ref_for/2 for test introspection. 5/5 in new delivery_retry_timer.sh; existing delivery_worker.sh 17/17 and delivery_retry.sh 11/11 still green. Conformance gate 771/771 (was 761/761; the +10 is the cherry-picked send_after suite). Closes Blockers #3. m2 is now feature-complete. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
