The per-model breakdown lives only in the "Models" section — never inline

Per-model numbers belong only under "Models", never inline on the Session or
Weekly line.
Times are printed in the **server's local zone** (`Europe/Prague`), taken from
the system — no zone is hardcoded. The session line loses its reset clause when
the history holds no rollover to anchor the window; that is correct output,
not a failure.
The Session line has two other shapes, both correct output and not a failure:
the percentage alone (the history holds no rollover to anchor the window), and
`window expired — the next one starts with the next request`.

## Reset times
`/api/usage` carries **no reset timestamps**, neither in the body nor in the
response headers (re-checked 2026-09-15). Both are derived.

- **Weekly:** next Monday 00:00 UTC, `until_next_monday()`. Matches the dashboard.
- **Session:** a 5-hour window anchored by the **first request after the previous
one ran out**, not a fixed grid. So `session_window_end()` takes the newest
rollover in `samples` and adds 5 h, and nothing is extrapolated past it — once
the window runs out there is no next time until a request opens one.
**Session: a 5-hour window anchored by the first request after the previous one
ran out** — not a fixed grid. The length comes from
[ollama.com/blog/transparent-pricing](https://ollama.com/blog/transparent-pricing):
the new plans dropped the "5-hour or weekly limits" this key still has.
**The reset is never guessed.** With no rollover in the history the Session line
carries the percentage alone; a confident wrong number is worse than none.
How the anchoring was established on 2026-09-15: usage sat unchanged at
0.077/21 requests through 05:00 UTC — a fixed grid would have zeroed it there
and the poller would have recorded it — and only reset when a request arrived
at 06:00, after a 93-minute pause. Reconstructing the agent's activity gives a
consistent chain: window 00:00–05:00, then 06:00–11:00, each opened by the
first request after the previous expiry. A fixed grid would additionally
require that request to land exactly on a boundary by chance.
So `session_window_end()` takes the **newest rollover in `samples`** and adds
5 h. A rollover sample marks the start of a new window, not a boundary that was
due anyway, which is why nothing is ever extrapolated past it: once the window
runs out, the output says the next one starts with the next request rather than
naming a time.
That it is a window and not a rolling counter was measured too — usage dropped
from 0.077/21 to 0.0/`{}` at once; a rolling counter decays gradually.
**The reset is never guessed.** An earlier version assumed a calendar hour and
printed "resets in 31 minutes" while the dashboard said "Resets in 2 hours" —
a confident wrong number is worse than none. With no rollover in the history,
the Session line carries the percentage alone.
Do not compare our countdown against the dashboard's to the hour: the dashboard
rounds an unknown way (it showed "4 hours" and "3 hours" seven minutes apart),
which is why the output prints the wall-clock time too.
**If the model is wrong, the report shows it.** `Rollover gap:` lines compare
consecutive rollovers against the 5 h window — gaps longer than the block
confirm request-anchoring, a gap exactly equal to it across a long idle stretch
would point back to a fixed grid.

## Continuous sampling
A cron job runs `scripts/ollama_usage_poll.py` every minute and appends to
`db/ollama_usage.sqlite` whenever anything changed (table `samples`; table `meta`
records every poll, so a gap can be told apart from a failed poll).

The report ends with `Rollover gap:` lines and a `Session window:` line —
when the window in progress started, when it ends, and how the observed
rollovers line up against the 5 h length.
The report closes with a `Session window:` line and `Last poll:`. From the second
recorded rollover on it also prints `Rollover gap:` lines, which test the window
