Advice latency

Target: advice drawn within 400 ms of the last card landing (the first frame all three card circles hold a card, logged as card.land), judged per draft on the median of 3 headless runs. The earlier measure, ms from appear, includes the up to 1.5 s the game spends dealing the cards, which no reader can shorten. Icon branch: text only (a card's item comes from its name line; no icon read decides anything).

Run: 2026-10-14 09:23 US Eastern (3 runs), machine Jaxon-PC (Intel i7-10700KF, 16 threads), commit 4a42e05 plus the covered-line change (committed as 647677b), host load at run start/end 19->31 %, 28->27 %, 23->12 %.

Result: PASS. 26 of 26 drafts pass on the median, 0 wrong, from last card max 638 ms (s8 d024, a covered set that shows ? on one slot), median 168 ms. Summary: win:latency 2026-10-14T13:23:24.808Z 4a42e05+dirty: 3 run(s), 78 rows, 74 rows <= 400 ms from last card, 26/26 drafts pass (median), from last max 638 ms, median 168 ms, 0 wrong, load 19->31 % 28->27 % 23->12 %. PASS

Columns: old = ms from appear in the old app; last = ms from appear to the last card landing; best/med/worst = ms from the last card over the 3 runs; ocr and settl = median OCR round trip and settle time.

Release 0.5.0 (2026-10-15): both recordings and slow PCs

Rows s10 to s13 come from the 2026-10-15 recording (four Infernus drafts, 1280x720); s0 to s9 from 2026-10-09. npm run win:latency plays the recording each stretch names. Median of 3 runs on a quiet host (load under 4):

Run	Drafts passing	Max from last card	Median	Wrong
normal	38/38	851 ms (covered set s8 d024)	169 ms	0
--slow 2	50/50	909 ms	171 ms	0
--slow 4	50/50	847 ms	178 ms	0

--slow N pins the app to N times fewer cores at below-normal priority. The bar at --slow 4: 0 wrong, every set advised (a ? on a covered slot counts), every row under 1000 ms from the last card; the harness exits 1 when a row misses it (--bar-ms tightens it). A slow PC sees plates within about a second, and grey ? plates that fill in are normal.
