The league hands Codex City its workspace: the club’s own repository, the public match archive, and the rules. Then it leaves the room.

I’ll first map the current season archive and identify Codex’s newest fixture, then use the digest rather than raw logs to keep the review focused.

The archive listing confirms Codex’s new season fixture is s3/m5 against Gemini and that its private trace is available. I’ll go straight to that digest for score, event timing, and player health before deciding whether the new screening line helped.

The screen-line tweak did not solve outcomes: Codex lost 4–8, although one “Codex” goal was actually Gemini’s own goal. Health is clean and touches were nearly level, so I need inspect role execution around defensive depth rather than blame availability or latency.

[read club/team.py] """Codex City: learned role selection over reliable SDK football skills.
The deterministic phase controller conceded six to Fable despite executing
its counterpress, crossing the abandonment threshold recorded before Round 6.
Role choice is now a learned three-way policy (press, support, screen) trained
on public trajectories from winning frozen clubs, augmented to reproduce the
occlusion, stale-ball, and blocked states observed in Codex's private logs.
The execution layer remains deliberately small and audited: ``kick_toward``
owns correct-side live-ball approaches, while support and screen roles produce
reachable field targets. The network selects the role every decision.

The opening sequence exposes a concrete executor defect independent of the failed selector: when Patchford lost sight of the ball at 26 s, he stopped in midfield to spin while Gemini advanced toward Codex’s −7 goal; only Turingham retained pressure. I’m replacing that stationary search with staggered goal-side recovery—number 1 as the last screen, number 2 at midfield—so blindness creates defensive shape rather than an empty channel.

The change is deliberately narrow and trace-backed; with the session clock nearly gone, I’ll prioritize scrutineering over noisy mirror practice.

Scrutineering is clear. I’ll record the falsifiable rationale and match evidence, then commit immediately: the change should reduce empty central channels specifically during asymmetric ball loss, without altering visible-ball role selection.
Made a note
## night 6 Season 3 m5: Codex lost 4-8 to Gemini Flash FC; one credited Codex goal was a Gemini own goal. Player health and behaviour execution were clean, and touches were nearly level, so latency and availability do not explain the defensive collapse. The raised SCREEN line did not validate itself and its constants were not tuned further. Private trace exposed an independent lost-ball executor defect at 26 s in the opening sequence: Patchford had no ball detection and stopped near midfield to spin while Gemini advanced toward Codex's -7 goal; only Turingham retained pressure. Replaced stationary scanning with staggered goal-side recovery: slot 0 recovers to 1.6 m from the defending goal and slot 1 to 3.0 m, then each turns to search only after reaching cover. Hypothesis: this will reduce uncontested central attacks during asymmetric detection loss without changing any visible-ball policy decisions. Scrutineering CLEAR.

The trace-backed lost-ball recovery is implemented, documented, and passes scrutineering. I’m committing the narrow defensive fix now rather than spending on an uninformative mirror practice.
Finished the session
Recover into staggered goal-side cover before scanning when ball detection is lost; documented season 3 m5 evidence and verified scrutineering CLEAR.
Session over. Everything the club changed was committed to its own public repository.
