UX-08 2d: plain log lines, the rest of the status page, and DOCS

Every WARNING and ERROR line is one plain line of at most 25 words, with
no card ids, capitals or semicolons; the reasoning of the ten longest is
on a DEBUG line. The ux08 allowlist is empty and its cap is 0 (43 -> 0).

The status page: the month-peak and peak-guard rows, the stale-reading
row, the top table (Why, Tariff, Arbitrage, Shadow mode, labels), the
Stopped banner and the line under the buttons, which now shows the plain
hint of each event instead of the raw action log. The Supervisor question
at start logs one line with a real reason.

Refusals are counted as shown (labels expanded, long cases driven), seven
were shortened, the card and parse errors lost their internals, a blank
value reads "empty", and the panel no longer files inverters.max_w under
the flat max_w. Option names lose "(JSON)", the NL texts are checked too.

DOCS gets a glossary (control board, isolator, Developer Tools) and card
ids move from headings to a "For installers" line.

 2. **Citations moved to DOCS.** Option descriptions say "Measured value, leave it unchanged" or similar, and the record behind the value is under "For installers: where the numbers come from". The UX-01 citation check in `test_translations.py` now checks the tab for that instruction and DOCS for the record.
 3. **What left the refusals:** the shipped default in the peak-reserve reason, the superseded-default note in the levy-table reason (DOCS already covers it), the endpoints of the withdrawn providers (DOCS "Energy price providers"), the plant measurement behind `slew_w` (DOCS, beside the setting), and the leg-specific paragraphs of the tariff-formula errors. Each reason keeps the rejected value, the limit and what to change.
 4. **Not rewritten:** errors that only a code defect can raise, such as plugin-contract and argument-type checks in `price.py`, `price_forecast.py`, `static_tariff.py`, `arbitrage.py` and `main.py`, which a home owner never reads. INFO lines such as the tariff-formula preview were also left.

+# UX-08 phase 2d: log lines, the rest of the status page, and DOCS
+
+The allowlist is empty and its cap is 0 (43 → 0). Every WARNING and ERROR line is one plain line of at most 25 words, with no card ids, capitals or semicolons (the semicolon rule now covers log lines too). **Unchanged:** every log level, every trigger and cadence, every notification id, every row's colour and when it shows, the banner cascade, and every refusal count.
+
+1. **No code prefixes on log lines.** Nothing outside the repositories greps them, except `/home/homelab/clampwatch.sh`, a one-off site watch from 2026-09-05 that greps `OUTPUT_CLAMP` and `Engagements so far`. `OUTPUT_CLAMP` is still in the reason the line quotes; "Engagements so far" is now "Cut back N times so far". The tests that found a line by its card id (`SAFETY-37`, `SAFETY-44`, `CONTROL LOOP DIED`, `UNGRADED`) now find it by its words.
+2. **Reason texts keep their codes.** A line quotes a watchdog's reason (`%s`), such as `STALE_READING: …` or `OUTPUT_CLAMP: …`. Those are the evidence an installer searches for and many tests pin them, so they were not rewritten. The line around them is plain.
+3. **Reasoning moved to DEBUG, not deleted,** for the 10 lines marked DROP-to-DEBUG (for example the 14 768 W history behind the over-rating alarm, why SAFETY-42 reports and does not act, and the Eneco card advice). The 25-word line keeps the action and the numbers. SAFETY-57's promise stays on the ERROR line, as an ordered pair: "until it changes, or 17 s after the command drops below 250 W".
+4. **The line under the buttons** showed the newest raw action-log entry (`OUTPUT_CLAMP …`, `FAILSAFE …: SIGN_DISAGREEMENT`, `ALLOCATOR …`). Each `log_event()` call now also names a plain hint from `messages.HINTS`, and the page shows that. The action log itself is unchanged, because tests and later analysis read it, and the page no longer shows it.
+5. **The top table.** *Why* is `messages.why()`: the arbiter's winner and limit in words ("Keeping the grid near zero: 440 W, held back by the peak limit"). `self.reason` keeps `Resolution.explain()` for the log and the checks. *Tariff*, *Price history*, *Arbitrage* and *Shadow mode* keep every figure TARIFF-11 and SAFETY-47 put there, each in its own slot, in words. Labels: *Battery level*, *Solar production*, *Power request*.
+6. **The month-peak row became two rows**, because one sentence of 15 words cannot hold the peak, its time, its share of the limit and TARIFF-13's coverage figure. The store's state at start (`restore_state`) left the row: it is the INFO line at start.
+7. **The peak guard rows** name the projection first and the limit second, as before (SAFETY-38). The blind row says what it means for the owner: the battery does not charge until the period can be measured again.
+8. **Wording that changed meaning-carrying words**: "command and meter point opposite ways" is now "the power went the wrong way" (banner) and "…went against what the add-on asked" (row). The N=1 banner still names the meter, the N≥2 texts still say "own power". The inverter range reads "up to 5 000 W each way" instead of "-5 000 W to 5 000 W".
+9. **Refusals are counted as shown.** Setting placeholders are expanded to label and key, and the long cases the 2c test found are driven through the validator. Seven refusals were shortened. The card refusals no longer show `c_eur_per_kwh`, `vat_pct` or "its own card", and a text that does not parse says "not valid near character N" instead of the parser's words. A missing value shows as *empty*, not `None`.
+10. **The panel's key match** no longer files `inverters.max_w` under the flat `max_w`.
+11. **The Supervisor question at start** is one INFO line with a real reason (a timeout's own text is empty, so the error type is named).
+12. **DOCS**: a glossary ("Words used on this page") explains control board, isolator and Developer Tools once. Card ids left the headings and sit on a *For installers* line under each. The links to the renamed headings were updated.
