re: OB hunt second attempt — saving verified, filter fixed, attach was frozen

Browse Source 
The incremental-save fix is verified. A fresh mission caught one e010 event at
t=241 s and wrote 1187 candidates to disk immediately; the turn timeout then
fired exactly as before, but this time the data survived. The session also
clears the candidate file at launch, since candidate offsets are only meaningful
within one emulator instance and resuming across launches would intersect
unrelated addresses.

The correlation itself was wrong though. It matched on the delta alone, so any
two float bit patterns whose integer representations differ by the loss count
qualified, and in a heap full of positions and velocities that is thousands of
words. The 1187 survivors were things like 1044450858, about 0.1f, and
3212461993, a negative float. Candidates must now also look like a counter --
a small non-negative integer in both samples -- which removes the noise by
construction instead of hoping the intersection washes it out.

The follow-up attach logged zero events across 520 s, which reads like the
combat-effectiveness limit again. It was not: 25 of its 26 samples were flagged
GUEST STALLED, so the guest was frozen for essentially the whole window. The
witness added last iteration did its job, and the lesson is about reading it --
the run summary quoted "0 events" first and the stall count only surfaced on a
deliberate check. A run's witness result should be the first thing looked at,
before any interpretation of what the run showed.

Still unfinished, with no address identified. What is needed is unchanged, two
or three e010 kill events in non-stalled samples, and the two obstacles are now
clearly separate: the freeze rate, and a pilot that manages about two
marked-fighter kills per five minutes.

🔴 `SYLPH_HZ=3` refuted as a lever: it gave the LOWEST frame rate (8/s) with the
most kills, so pilot polling is not the throttle.
* ✅🔴 **(2026-08-24) OB hunt, second attempt.** ✅ **Incremental saving verified**
— one `e010` event at t=241 s wrote **1187 candidates** to disk before the turn
timeout fired; session now clears the file at launch since offsets are only
valid within one emulator instance. 🔴 **The correlation had no value filter**:
survivors were float bit patterns (1044450858 ≈ 0.1f) whose integer forms
differed by the loss count. Fixed — candidates must be small non-negative
integers (`0 ≤ v < 1000`) in both samples. 🔴 **The attach was FROZEN**, not
merely unproductive: **25 of 26 samples flagged `GUEST STALLED`**. The witness
worked; the summary just quoted "0 events" before checking it. **Rule: read the
witness FIRST, before interpreting what a run showed.** ❔ Still no address;
needs 2–3 `e010` events in non-stalled samples.
* ~~🚧 BLOCKER: t=210/240 unreachable in one turn~~ — **superseded, see above**;
it rested on an untested assumption that a turn is one shell call. 595 s shell cap − ~220 s boot (a ~190 s title movie that cannot be
tapped through) − ~25 s startup = **~350 s observation ≈ 193 game-seconds**.
