From 00dc0162aa9da3fd5548641ff93e806ec4a0d374 Mon Sep 17 00:00:00 2001 From: Sylpheed RE agent Date: Thu, 27 Aug 2026 03:07:33 +0000 Subject: [PATCH] re: quantify why the OB kill test keeps failing -- attackers are damaged, not missed Fourth Stage 02 run: 520s of pilot with SYLPH_PREFER=e010 (198 fire=1), per-class counts every 10s, OB+TIME throughout. ARRIVAL TIMING n=4: 008 first at 02:05.00 (step bracket contains 120), 012 first at 03:45.47 (bracket contains 210), then 012 held 3.5 more minutes with no fall and no 016. THE BLOCKER IS MEASURED, and it is not aim. Reading hull at pos+0x154 for every live e010 at the end: 14 of 16 are damaged, hulls 360..500, lowest 360/500 = 28% gone. The shots land; they just do not finish. A kill needs roughly 3-4x longer on one target than ~8 minutes of combat produced. The contrast with the control shows the mechanism is hit points: e007 turrets (HP 100) lost ~9 dead, 106 -> 97 live, while e010 attackers (HP 500) lost none and the floor never moved off 16. Decrement therefore still unproven after four runs, and "fly longer" is not a fix since ~half of runs end early. Options recorded for a redesign: point the pilot at the WEAKEST attacker (hull is readable per entity; one is at 360/500), use missiles (never deliberately fired), or wait on a scripted kill. --- docs/re/ob-counts-marked-attackers.md | 56 +++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) diff --git a/docs/re/ob-counts-marked-attackers.md b/docs/re/ob-counts-marked-attackers.md index 886afb2b..e5da21a7 100644 --- a/docs/re/ob-counts-marked-attackers.md +++ b/docs/re/ob-counts-marked-attackers.md @@ -400,3 +400,59 @@ effectiveness, not instrumentation — `pilot-never-fires.md` and the because turrets are nearer and far more numerous. ❔ Options not yet tried: pick a lone attacker while the squadron is still inbound, or wait for the wingmen/ACROPOLIS guns to kill one (which counts just as well). + +--- + +# 2026-08-27 (fourth run) — why the kill test keeps failing, quantified + +520 s of `pilot.py` with `SYLPH_PREFER=e010` (198 `fire=1`), per-class counts +every 10 s, OB+TIME sampled throughout +([capture](captures/ob-fourth-run-timeline.png)). + +## ✅ Arrival timing, n=4 + +`008` first at **02:05.00** (step ∈ (111.1 s, 125.0 s] ∋ **120**); `012` first at +**03:45.47** (step ∈ (209.7 s, 225.5 s] ∋ **210**); `012` then held for a further +**3.5 minutes** to 07:07.21 — no fall, no `016`. + +## ✅ The blocker is a DAMAGE RATE, and it is now measured + +The obvious reading of four failed runs is "the pilot cannot hit attackers".
