-- name: FailStaleTasks :many
-- Fails tasks stuck in dispatched/running beyond the given thresholds.
--
-- Each branch pairs a wall-clock deadline with a task-appropriate liveness
-- signal, so the sweeper only kills tasks whose owning daemon is no longer
-- proving it is alive:
--
--   * Dispatched: `prepare_lease_expires_at` is refreshed every 15s by the
--     daemon between claim and StartTask (see startTaskPrepareLeaseExtender).
--     A live lease excludes the row.
--
--   * Running: no per-task lease is renewed once StartTask fires, so we key
--     off the daemon-wide heartbeat instead — `agent_runtime.last_seen_at`,
--     which the daemon bumps every ~15s while it is up. A running task whose
--     runtime is `online` AND whose `last_seen_at` is within
--     @runtime_stale_secs is treated as alive and is NOT killed by this
--     wall-clock backstop, even after `started_at` exceeds the running
--     timeout. This is what lets healthy multi-hour research / training runs
--     survive on self-hosted deployments (MUL-4107): the daemon side is
--     bounded only by inactivity watchdogs (idle / per-tool), so the
--     server-side wall clock must not shadow that with a coarser cap.
--
-- The daemon-dead case is the primary responsibility of `sweepStaleRuntimes`
-- (which mixes DB `last_seen_at` with the Redis LivenessStore and calls
-- `FailTasksForOfflineRuntimes` in the same tick). The wall-clock branch
-- here is a defensive backstop for pathological cases where a runtime row
-- somehow retains status='online' with a stale DB heartbeat for longer than
-- the wall clock allows.
--
-- runtime_id IS NULL: a running row with no runtime is by definition not
-- proving liveness, so the wall clock is allowed to fire — same shape as
-- the legacy pure-wall-clock behavior for that (rare / historical) case.
--
-- waiting_local_directory rows are intentionally excluded: the daemon owns
-- the wait (with its own ctx-driven timeout) and a legitimate queue ahead
-- of this task can exceed the dispatch / running timeouts without being
-- "stuck". If the daemon dies, RecoverOrphanedTasksForRuntime reclaims
-- those rows at restart.

-- is offline, we still need to drain the historical 87k+ doomed rows and
-- handle edge cases where a runtime goes offline AFTER a task is already
-- queued (the admission check protects new enqueues, not in-flight queue
-- depth).
--
-- Concurrency safety: the daemon's claim path may race with this sweeper to
-- transition the same row out of 'queued'. We protect against that two
-- ways:
--   1. The CTE selects victims with FOR UPDATE SKIP LOCKED so a row that is
--      currently being claimed (or otherwise locked) is skipped — no lock
--      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.
-- Capped via LIMIT inside the CTE so a single sweep tick cannot monopolise
-- the DB when the backlog is large — the sweeper drains the rest on
-- subsequent ticks.

-- trigger_comment_id becomes a coalesced ("also cover") comment and
-- @new_trigger_comment_id becomes the new trigger, so the injected prompt shows
-- the latest deliberate instruction while the single run is still told to
-- address every folded comment.
--
-- Target is restricted to the single 'queued' task on purpose (MUL-4195 review
-- rounds 2–4). This merge is only reached when HasPendingTaskForIssueAndAgent
-- matched a 'queued'/'dispatched' task, and 'dispatched' is deliberately NOT a
-- target: a dispatched / waiting_local_directory / running task has already had
-- its claim response built. Folding afterward would add a planned id that is
-- absent from that response's delivered_comment_ids receipt; completion
-- reconciliation handles it instead. 'deferred' is also NOT
-- a target: a deferred row is an assignee-fallback escalation with its own
-- fire_at/promotion lifecycle, and it never sets AlreadyPending
-- (HasPendingTaskForIssueAndAgent only looks at queued/dispatched). If a newer
-- deferred fallback and an older queued task coexisted, a status-IN target would
-- pick the deferred one by created_at and steal the coalescing target away from
-- the queued run that is actually about to be claimed — so we match ONLY the
-- queued row (the idx_one_pending_task_per_issue_agent unique index guarantees
-- at most one). coalesced_comment_ids remains the pre-claim plan; the claim
-- path records the actual embedded subset in delivered_comment_ids.
--
-- Recompute-on-merge (MUL-4195 review must-fix #1): originator_user_id,
-- runtime_mcp_overlay and runtime_connected_apps are re-stamped to the NEW
-- trigger comment's originator (computed by the caller). Earlier this only
-- repointed the trigger and kept the old originator's overlay/attribution, so a
-- run answering user B's comment could execute under user A's connected-app
-- capabilities and audit identity. Re-stamping means the single coalescing run
-- carries the latest deliberate instruction's originator and the matching
-- overlay — no cross-user capability bleed, no stale attribution. This also
-- removes the previous originator gate + fresh-enqueue fallback, which could not
-- create a second task anyway (the idx_one_pending_task_per_issue_agent unique
-- index allows only one queued/dispatched task per (issue, agent)) and therefore
-- silently dropped the mismatched-originator comment.
--
-- Returns pgx.ErrNoRows when no queued task exists (it was claimed/started
-- between the dedup check and this call, or the only task is already
-- dispatched/running). The caller must NOT blindly enqueue a fresh task in that
-- case — a dispatched sibling would trip the unique index — it defers to
-- completion reconciliation unless no active task exists at all.
