//  1. The CTE selects victims with FOR UPDATE SKIP LOCKED so a row that is

//     contention with the dispatch path, and we won't queue up behind it.
//  2. The outer UPDATE re-checks status='queued' AND the TTL predicate at
//     apply time. If a daemon claimed the row between selection and update
//     (e.g. lock released after the claim transaction commits), the row is
//     already 'dispatched'/'running' and the WHERE clause filters it out
//     so we cannot clobber an in-flight task.

// the DB when the backlog is large — the sweeper drains the rest on

// session may replay the same stuck state.

// shape: a legacy row tagged 'agent_error' (pre-MUL-1921), a deploy-window
// row that the old code wrote between migration and rollout, or a future
// error format that escapes the daemon classifier all still get filtered
// here as long as the canonical Anthropic 400 marker is present in the
// error text. Migration 079 backfills the failure_reason column itself,
// so observability stays accurate; this clause guarantees session resume
