-- Migration 002: add per-inbox delivery sequence numbers.
|
|
--
|
|
-- Adds a `seq` column to the deliveries table and a separate counter table
|
|
-- that tracks the next sequence number per (recipient_key, channel_id) inbox.
|
|
-- The counter is atomically incremented on each enqueue via an UPSERT so
|
|
-- sequence numbers are gapless even under concurrent inserts.
|
|
--
|
|
-- Requires SQLite >= 3.35 (RETURNING clause support; available on Ubuntu 22.04+).
