The check also runs immediately when the worklog tab regains focus, and is fully visibility-gated (a hidden tab spawns zero `wl`/`herdr` processes). The same pane-title lookup drives the selection list's **in-progress marker**: an item with a matching pane is shown as `in-progress` (marker + Group N) even when its worklog status is still `open`, and loses the marker when the pane closes. See [Hydrator](#hydrator-self-healing-in_progress-claims-wl-0msojlzd9004p8pi). -- **Mode-switch worker (activity-gated proxy mode switching)** — Automatically switches the llama-proxy between fast (cloud) and cheap (local) modes: agent-route commands fire an immediate fast switch (fail-open), while a full operator-idle window plus a proxy-idle check triggers the cheap switch (fail-closed). The proxy URL reuses `downtimeProxyUrl` and the plugin's switches are manual overrides that the proxy's own time schedule reclaims. See [Mode-switch worker](#mode-switch-worker-activity-gated-proxy-mode-switching-wl-0msn3fwv5008kqe9). +- **Per-request priority (`X-Priority`)** — The proxy's retired fast/cheap operating mode is replaced by a per-request priority. Herdr maps each dispatched work item's priority onto a request priority and conveys it as the pane-launch environment variable `HERDR_REQUEST_PRIORITY`, which the Worklog pi extension turns into the `X-Priority` provider header. See [Request priority](#request-priority-per-request-x-priority). - **Work-item pane indicator** — The selection list shows a green circle icon (🟢) in the icon prefix of every item with an open work-item pane in the current workspace: a pane whose title carries the work-item ID (the dispatch pane-title convention preserves the ID as a trailing suffix). The icon appears exactly when such a pane is open and never otherwise (producer's rule, WL-0MV1BWETT005GSUJ) — it is pane existence, not a live agent status. The worklist also records which pi agent pane is attached to each dispatched item — including the dispatched command — persisted to the gitignored `.worklog/agent-panes.json`, shared across worklist panes (used for the hover tooltip). The icon occupies a fixed-width slot so the item-ID column never shifts.

Key settings in - `autoRefresh` — Enable periodic auto-refresh of the work item list (default: `true`). Refresh ticks are **DB-change gated**: when the worklog DB has not changed since the last cycle, an auto-refresh tick spawns zero `wl` processes (no `wl next`, no `wl list`, no children fetches, no action-count fetch). The gate uses the wl CLI's monotonic per-worklog-dir state counter (`~/.cache/wl/state/.json`) as a cheap cross-process signal; a read error fails **open** (the cycle runs). Manual `Ctrl+r` always runs (WL-0MSJ1OLTL009N4IQ). - `refreshIntervalMs` — Interval in ms between auto-refreshes (default: `30000`). Refresh cycles are single-flight with a **trailing refresh**: a tick/request that fires while a refresh is still awaiting its `wl` calls sets a pending flag and coalesces to a single trailing cycle that runs after the current cycle completes — without unbounded queuing (at-most-one trailing per in-flight cycle). This guarantees that a background command's `onExit` refresh is never silently dropped when it overlaps another fetch, so Herb-selection style chords such as `u p c` always land after one dispatch (WL-0MSBVYBMD004007C, WL-0MTIB7JAN004MQ8N).

A hung `wl` child is killed after the bound, the refresh fails with a `Refresh failed` toast, the single-flight guard is cleared in `finally`, and the next tick retries — a hung spawn never wedges `refreshInFlight` permanently (WL-0MSJNJXX2001NMHS).

When the cached mode says `fast` the command - * path re-reads the actual mode first, so a schedule-driven flip to cheap - * never suppresses the explicit fast request (WL-0MUWIHUL2000JEFR). The - * fast switch fires on the instance that received the command, whichever - * pane that is — see the leader note below. - * - **Leader-only cheap switching (WL-0MU6MXCZZ007ZXT9, AC1):** only the - * downtime leader (`DowntimeWorker.isLeader`, reused — no separate - * election) runs the idle cheap-switch logic. Non-leader instances skip - * `tick()` entirely, so idle panes can no longer flip the shared proxy to - * cheap behind an active pane's back (the flip-flop fix). The leader probe - * is read live each tick, so a leadership handover is honoured on the next - * tick (AC5). - * - **Shared activity broadcast (AC2):** every instance writes its latest - * operator-command timestamp to `mode-activity.json` in the coordination - * directory (`getMachineCoordinationDir()`, the same dir as the downtime - * leader lease) and the leader reads it each tick. The idle clock is the - * max of the local clock and the shared timestamp, so the proxy stays fast - * while **any** pane has recent activity. A read/write failure falls back - * to the local clock (AC6, fail-closed: never a premature cheap switch). - * - **Cheap switch on idle:** on each tick (scheduler task, or the downtime - * dispatcher's `onProxyIdle` callback — the leader is the only pane that - * runs that dispatcher), when the operator has been idle - * (no agent-route commands on any pane) for ≥ `modeSwitchIdleThresholdMs` - * **AND** the proxy reports idle (reusing `evaluateIdle` from - * downtime-worker.ts), the worker POSTs `/admin/set-mode {"mode":"cheap"}`. - * **Per-slot operator gate (parent WL-0MT9F67Y3008S0PR, decision 1.a):** - * when the proxy serves per-slot identity (`slots[]` valid per - * `parseLlamaStatus`), the idle gate requires only ≥ 1 free slot - * (`evaluateIdle(status, DOWNTIME_PANE_MIN_FREE_SLOTS)`) — the spare-capacity - * semantics shared with the downtime dispatcher, whose autonomous - * query/lease work holds the OTHER busy slots. A downtime pane is exactly - * the work the operator wants to keep running while the proxy runs cheap, - * so the busy slots must **not** delay the switch (Q4b decision; - * accepted tradeoff: a fast-mode downtime request in flight during the - * mode restart is killed and retried by its client). Without per-slot - * data the all-slots-free fail-closed fallback is unchanged - * (`evaluateIdle(status, 0)` — full global checks). In every case a busy - * proxy (server down, model switch, or 0 free slots) **delays** the - * switch — it never kills in-flight work. - * - **Model-cooldown gate (WL-0MV5638ZS005I5XQ):** before the cheap - * decision the leader reads the machine-wide cooldown signal - * (`readModelCooldowns`, the same coordination dir as - * `mode-activity.json`). While any entry is active (`cooldownUntil` in - * the future) it holds **fast** — a pane sitting in proxy backoff holds - * no slot, so the proxy looks idle and the switch would add concurrency - * (cheap has more slots than fast) during provider exhaustion. The hold - * is bounded by `cooldownUntil` (no latch) and machine-wide, so a - * cooldown for any worklog root suppresses the shared switch (AC4). An - * unreadable/corrupt signal is fail-closed (hold fast, logged); an - * *absent/empty* signal is `[]` and does not suppress the switch - * (WL-0MV5639X70029BOI). The fast-on-command path is unaffected. - * - **No redundant switching / no hammering:** the worker skips a switch when - * the persisted mode already matches the target (tracking last-known mode, - * refreshed via `GET /admin/mode` on each poll). At most one switch per - * state change; a `409` (mode-switch restart in progress) is treated as a - * no-op and retried on a later tick. - * - **Fail-closed everywhere:** endpoint failures, timeouts, network errors, - * and ambiguous responses yield no switch and never crash or block the - * plugin. On plugin restart the idle clock resets to "active now" - * (fail-safe: the proxy stays fast until a fresh full idle window passes). - * - **Coexistence with the proxy's built-in schedule:** the plugin's - * switches are manual overrides (the API's native semantics, - * LP-0MSMF25V9002AY1J); the proxy's time-based schedule (cheap - * 01:00–10:00, fast 10:00–01:00) reclaims control at its next boundary. - * Documented behavior, not a conflict. - * - * The proxy URL is shared with the downtime worker (`downtimeProxyUrl` — no - * separate URL key), and the existing `/llama/local/status` idle evaluation - * from downtime-worker.ts is reused. - * - * **Idle-trigger sources (WL-0MU4MKVR4005WPBJ):** the cheap check runs from - * two triggers — (1) the independent `mode-switch` scheduler task on - * `modeSwitchPollIntervalMs`, and (2) the downtime dispatcher's - * `onProxyIdle` callback, fired with the fresh proxy status whenever the - * dispatcher's own poll observes the proxy idle (before it dispatches the - * next item). Trigger (2) removes the up-to-one-poll-interval delay so a - * downtime item is served by the cheap pool; trigger (1) remains the - * fallback when the downtime worker is not polling (disabled, non-leader, - * paused).
