glenn schrooyenandClaude	2929ece7da	SAFETY-125 round 2: the one-inverter maintenance charge is sized to the room too ... Owner 2026-10-29: fix N=1 in this hotfix. _charge_headroom() no longer returns early at one inverter, so the N=1 cheap-window maintenance charge is held to charge_room_w() as at N=2; SAFETY-84's site-stop rule stays N>=2 only (at N=1 such a stop outranks the shaping anyway). The guard no longer steps in and gives power at each quarter's end during that charge. test_safety125.py: N=1 maintenance on 5 s and 10 s meters with late readings, with and without a banked peak; the row in an N=2 maintenance charge and in shadow mode; edge cases (blind past the hold, a start mid-quarter, the summer-time change, the forecast in W, a 10 s meter, the last second). test_safety84/87: three N=1 pins move. test_safety119: its quarter-edge hand-back runs keep the old N=1 sizing as a fixture, plus a check that with the new sizing nothing hands back. CHANGELOG, DECISIONS, DOCS follow. Co-Authored-By: Claude <noreply@anthropic.com>	2026-10-29 14:57:39 +01:00
Claude (SAFETY-125 review)	6eebd4882b	SAFETY-125 review: guard row and Home line within UX-08 limits; N=1 maintenance named ... - The over-the-limit rows ran over STYLE's 15 words (EN 16/19, NL 16/21) and two Dutch Home sentences over 12 words; they were not in the samples, so test_messages/test_ux46 never saw them. Now: "Peak guard: grid charge limited, at this rate 5 814 W, over 5 413 W" / "Piekbewaking: laden beperkt, aan dit tempo 5 814 W, boven 5 413 W", "...idle, at this rate ..., over ..." / "...in rust, aan dit tempo ...", NL Home "Laadt minder van het net om onder 5,4 kW te blijven." and "Zou minder van het net laden om onder 5,4 kW te blijven." The rows and the line are added to the samples. The under row is unchanged. - CHANGELOG known issues and the DECISIONS note: at N=1 the maintenance charge is not sized to the room, so SAFETY-99 still applies to it. - DOCS: the peak guard row's new words.

glenn schrooyenandClaude	88ab8a50e3	SAFETY-125: a grid charge counts a late meter reading's seconds; the guard row says "over" when it is ... A meter reading late near a quarter's end left seconds the projection did not count (SAFETY-99), and charge_headroom_w() read them as room: the cheap run (and price trading, and the N=2 maintenance charge) went back to full power in the quarter's last seconds and the quarter could land over a banked month peak or the cap. peakguard.charge_room_w() counts those seconds at the held reading for the charge only; the guard's floor is unchanged. The guard row said "idle, heading for 5 814 W, under this month's 5 413 W peak". Over the limit at the current rate the row and the month-peak line now say so, and that the grid charge is cut back. Version 0.19.2, CHANGELOG, DECISIONS. test_safety125.py new; the lag pins in test_price_run_fixes.py and test_opt20.py and the AST pin in test_arbitrage.py follow the change (see the pull request).
