00SUMMARY DETERMINISTIC

Gained two places. Race pace was P3 of the grid; the result was decided by S2 (−0.31 s/lap to the car ahead all race) and by pitting one lap late (≈1.4 s lost to the undercut from P5). The engine made 23 calls, 19 of them proved right in hindsight.

07ACTIONS FOR NEXT SESSION DETERMINISTIC

Sector 2 is the weekend. −0.31 s/lap to the car ahead in every session. Evidence: §02. Record the next Bahrain session with --record full for the corner split.
Trust the pit call. The NEG at L12 cost the position to P5 (≈1.4 s). Evidence: §04 row 2; undercut projection 0.78 confidence proved right.
FL management. 23% of green laps HOT on FL; the other three corners < 5%. Evidence: §03. Thermal call fired on 3 laps, ACK on 1.
Rule tuning: ers_high_into_corner graded noise 2 of 2 this session; consider raising its cooldown. Evidence: §05 grades.

generated from rules over the debrief data: largest sector loss, any NEG that proved right, thermal share > 20%, any rule graded noise ≥ 2×

Your race was won and lost in the same place as your quali: sector two. The gap to Norris there is steady at about three tenths regardless of compound or fuel load §02, which points at a line or a braking reference rather than tyre state — the FL thermal spikes §03 happen on laps where S2 is not worse, so heat isn't the cause here.

The lap-12 undercut call was correct and you overrode it §04. The engine's projection had you 0.8 s ahead of P5 after the stop; the extra lap on 12-lap-old mediums cost about 1.4 s and P5 emerged 0.7 s in front. Worth noting the engine only had 0.78 confidence — the pattern to look for next time is "P1 call + confidence > 0.7", which has been right on all four occasions this season.

On the positive side: your consistency on the hard (σ 0.24 s) was the best in the field §01, and the decision to stay out at lap 21 was right by a clear margin.

Advisory prose over the deterministic sections above; it never changed a decision. Every claim links to the table it was read from — if a claim has no link, treat it as unverified.

> was the lap-30 call correct?

There was no lap 30 — this was a 28-lap race. If you mean the last strategy call, that was lap 21 (“free stop available”, screen only §04); you stayed out and the hards held to the flag, so yes.
