 every figure in this section was given, now over a smaller binary.
 
+It was reset a fifth time on 2026-09-23, when senior-dev moved inside the binary
+(`internal/seniordev`, the built-in programs wave). Like furrow's, this one is a
+decision and not a drift: the owner's direction is that the programs codeaf hands
+a whole task to are built into every codeaf build and exist nowhere else, so the
+limit rises by what the engine weighs. Measured before (`5cf6a821e`) and after
+(`45e505550`) it landed, with the flags `make build` uses, on Go 1.27.0:
+
+| platform | before | after | what senior-dev cost |
+| --- | --- | --- | --- |
+| darwin/arm64, furrow staged | 54,018,770 | 56,493,874 | 2,475,104 |
+| darwin/amd64 | 58,504,000 | 61,279,360 | 2,775,360 |
+| linux/arm64 | 52,560,032 | 54,984,864 | 2,424,832 |
+| linux/amd64 | 57,421,984 | 60,133,536 | 2,711,552 |
+
+Only darwin/arm64 had its furrow artifact on disk, so the other three rows are
+weighed without theirs: each difference is exact, and each absolute figure is
+short by that platform's artifact, about three megabytes. The budget rises by
+the largest difference, to 57,400,000 — this change's bill and nothing else.
+
+AND THE TABLE SHOWS A BILL THAT WAS ALREADY OWED, which this reset does not
+fold in. Before senior-dev, darwin/amd64 and linux/amd64 already weighed more
+than 54,600,000 without their furrow artifacts, and linux/arm64 was within about
+two megabytes of it before its own was added: the growth since the fourth reset
+crossed the cap everywhere but the laptop the budget is usually checked on. The
+CI size job reports it and does not block (`ci-full.yml`'s `size`), for the
+reason that job gives — which architecture the budget is measured on has to be
+agreed first — and that agreement, not a larger number here, is the fix.
