Review comments at @desktop/src/features/settings/SchemaForm.tsx:
- Line 43: Update the label for models.background_on_battery so it names the
usual battery limits the toggle lifts or explicitly states that upkeep remains
paused at or below battery_critical_percent.
Review comments at @sentient/llm/jobs.py:
- Around line 259-260: Move the upkeep battery-hold check using `_battery_hold`
ahead of the chat stall-valve early return, so upkeep at or above `UPKEEP_RANK`
remains deferred until the battery wait expires; preserve the stall valve’s
chat-deferral behavior.
Review comments at @sentient/llm/power.py:
- Around line 81-82: Update the numeric override validation in read() to accept
ASCII digits only before converting raw with int(), so non-ASCII digit
characters are ignored as invalid overrides without raising ValueError; preserve
the existing 0–100 range check.
- Around line 155-157: Update the battery loop in _linux() to collect capacity
only from batteries marked as discharging, rather than retaining the first
battery’s capacity. When multiple batteries are discharging, report the lowest
capacity as the conservative percentage.

…time Since #279 all background model work waited for the charger, so a laptop used all day on battery never ran memory upkeep, the user model, dreams or suggestions. Now only Sentient's own upkeep goes easy on battery: it runs while the battery is above models.battery_min_percent (40), after models.battery_idle_s (300) without chatting, in bursts at most every models.battery_upkeep_every_s (1800), waits at or below models.battery_critical_percent (15), and is never held longer than models.battery_max_wait_s (7200). A call the cap lets go opens a burst so the rest of its pass follows. Tasks are never held for the battery. The battery check now reads the level too, and SENTIENT_DEBUG_BATTERY fakes it for tests and debugging. model.busy reports "battery_low" next to "battery", and the title bar says "Waiting: on battery" / "Waiting: battery low". Closes #296

Ignore non-ASCII digits in SENTIENT_DEBUG_BATTERY, read the level only from discharging batteries on Linux (lowest wins), say that the no-limits switch still waits at low battery, and note why the chat stall valve comes before the battery holds.
Upkeep a person starts from the window (Dream now) is user-requested: on battery only a critical level (and the wait cap) holds it, and it opens no burst for scheduled upkeep. Nightly dreams and other scheduled upkeep keep the limits.

- Around line 320-323: In the waiter continuation around `_start_burst`, keep
cap-released requested work on a separate prompt path instead of opening the
shared burst while `w.held` is `battery_low`. Ensure `_battery_check` continues
holding scheduled upkeep until its own cap, and add a regression test for a
cap-released requested call followed by scheduled upkeep.

- Around line 293-294: The cap-released burst in `_asked_open()` currently
applies to any later `requested=True` call while open. Track the identity of the
request that reached the cap through `detached()`, and allow the burst only for
calls belonging to that same request; later manual requests must still respect
their own `battery_max_wait_s` cap.

Each requested context gets its own id; the burst the cap opens for requested upkeep is used only by calls of the same press, so a later Dream now waits for its own cap at critical battery.

Summary
On battery, only Sentient's own upkeep goes easy now. Tasks you scheduled are never held for the battery.
sentient/llm/power.py: the battery check now also reads the level (WindowsGetSystemPowerStatus, macOSpmset, Linuxcapacity).SENTIENT_DEBUG_BATTERY=ac|battery|<0-100>fakes the reading. It is for tests and debugging only, logs a warning while set, and is documented in docs/API.md and docs/DEVELOPING.md.model job held: ... (<which limit>),upkeep burst on batteryandmodel job released: ... (models.battery_max_wait_s).model.busy.deferred_reasongains"battery_low"(docs/API.md). The title bar now shows Waiting: on battery or Waiting: battery low, with a tooltip saying your chats and tasks still run on time. The five new options appear in Settings > Models > Sharing your local model.Evidence
Real engine on port 8789 with a fresh
SENTIENT_HOME, all roles onollama_chat/qwen3:8b, the Ollama lock held for each run. Test settings:battery_max_wait_s: 180,battery_idle_s: 60,battery_upkeep_every_s: 180,tasks.tick_seconds: 5.Before: in #279's real test, profile upkeep's model call waited indefinitely on battery. Scheduled tasks waited too.
After, critical battery (
SENTIENT_DEBUG_BATTERY=10): upkeep is held, the scheduled task runs on time, and the cap releases upkeep after exactly 180 s. The next call of the same pass then goes without waiting.(An earlier run without the burst rule held that follow-up call for another full cap. That run is why the burst rule exists.)
After, battery above the threshold (
SENTIENT_DEBUG_BATTERY=70): upkeep waits for the idle delay, then runs in a burst. The next chat's upkeep waits for the next burst window.App (built,
smoke.mjs, Maya Rao seed,SENTIENT_DEBUG_BATTERY=30): the evolution tick's summary call was held (model job held: skills qwen3:8b (battery, on battery at 30%: not above models.battery_min_percent; ...)). The title bar shows an amber dot with Waiting: on battery next to Stop all. I looked at the capture. In an earlier capture of the same profile, its seeded tasks were running on battery, and the indicator read "Model busy · a task +1". Settings > Models > Sharing your local model lists the five new options with their descriptions and units (%, s).Tests:
pytest -q: 1434 passed, 2 skipped.ruff check: clean.npm run typecheckandnpm run build: clean. New unit tests cover: tasks run at critical battery, upkeep needs more than the minimum, the idle delay, bursts, the cap plus pass follow-through, the no-limits switch not applying at critical, no overlap, Linux and macOS level parsing, and the debug override.Follow-up: Dream now is user-requested (34fc797). Upkeep a person starts from the window (
POST /api/memories/dreams/run) runs indetached("memory", requested=True). On battery, only a critical level (and the cap) holds it, and it opens no burst that scheduled upkeep could ride along on. Nightly dreams keep the limits. Real check with qwen3:8b, default limits:App at a faked 10% (seeded Maya profile, with seeded tasks archived and channels and deliveries turned off first): the title bar shows Waiting: battery low with an amber dot. Unit tests: Dream now at 20% with idle and burst limits skips them, scheduled upkeep stays held, at 10% it is held as
battery_lowuntil the cap, andstart_run("manual")runs as requestedmemory.pytest -q: 1438 passed, 2 skipped.After review (f36d701, then the per-press scoping): when the cap releases a Dream now at critical battery, the rest of that press follows in a burst of its own. Scheduled upkeep never rides that burst, and neither does a later press; each waits for its own cap. Unit tests cover both.

Door: two-way
Plain revert. There are no schema or data changes, and the new config keys have defaults.
Blast Radius: scheduling
All local model calls go through this scheduler. Laptops on battery will now run upkeep (and use more power) where before it waited forever. Dream now skips the battery limits except at critical level; User model refresh and skill "Review now" were already interactive requests and still never wait.
