The Landfall's Three When Every Team Has Them

Check-in report CI-016. Paul Richeson, treadcore.org; Claude Code (Claude Opus 5.5) as the pair. 19 October 2026. Companion records: journal 0065; LAB-REPORT-BRAIN.md section 39; CI-015.

Abstract

CI-015's reverse census read even where the forward read +2.31. This step took an absolute reading: every team on the new defaults against every team on the old (LR 27's null), on the same 16 seeds. Boats lost on the run for the beach nearly halve (165 to 89), but deaths in a dodge rise by about as many (354 to 434). The death rate is unchanged, the matches run 4.5% longer, and the team spends 13% more time alive. The deaths move ashore. This explains the asymmetry, and points the next step at the dodge's untuned numbers.

Index terms: absolute evaluation, attrition, displacement, defaults.

I. Introduction

A. Intent

Backlog 38: the three when every team has them.

B. The prompt

yes all three on. commit. push. continue backlog

(The same message as CI-015; this is its continuation.)

II. Decision Log

#CauseDecisionNot taken, and why
D1The census sets only the trial team's weightsLR 27's null as the all-old reading; a null now as the all-newA base-weights option in the census: not needed while the old defaults are a recorded null
D2Play at the old defaults unchanged since LR 27The two runs comparable on seeds 0–15
D3F: landfall down, dodge up, rate the sameThe deaths move ashore; the defaults stayReverting: the matches are longer, as goal 5 asks, and no worse in deaths
D4F: dodge deaths 51% of the held-last codesNext: the dodge's numbers to an honest tuner (23)Another landfall part: its share is down to 10%

III. Methods

CENSUS_ACTS=1, every team on the defaults, CENSUS_SEED0 0, 6, 11 with CENSUS_SEEDS 6, 5, 5; naval.map, 900 s, respawns 3, the fair census. Against LR 27's log (build/lr27/null-acts.log), the same configuration at the old defaults. Absolute counts summed over the three ranges. No pairing by seed, so no standard error.

V. Discussion

  1. Saved tanks find the next danger. The landfall's parts move deaths from the water to the shore, and the rate stays where it was. A relative census shows that as a gain only while the opponents still lose their boats.
  2. Absolute readings belong in every promotion. Deaths, living time and match length sit beside the relative score from now on.
  3. The dodge is now half the deaths. It pays (CI-006), and its four numbers were first-guess constants. That is a tuning problem, and the tuner (backlog 23) has to be made honest, against the fair census and its error, before it is trusted with them.

Next: backlog 23 on the dodge's numbers.
