Before: next @ 6bde511 has four rows over their brotli cap after #4511, though each is within the 20 B minified allowance. Those rows are hydrating no-stores (+43 B), base server components (+29 B), compiled live server components (+11 B) and observe + attribution (+4 B). #4510's size check is red on five rows.

After: the ledger records the post-#4511 sizes, plus #4510's growth, which the maintainer accepted on 2026-10-31. #4510 goes green once next is merged into it.

How: I measured next @ 6bde511 and #4510 with next merged in (bc3dfdf). For each row I took the larger of the two. Caps are measured brotli + 10 B, rounded up to 0.01 KB. Rows that are only past the minified allowance re-record minified and keep their caps. The local size.mjs gate passes on both builds with this ledger. The local #4510 numbers match its CI run on 5429aa0.

Hello world is unchanged and stays under its 9.98 KB cap.

Size-Exception: frozen floors hydrating (no stores), base server components and live server components are re-recorded for #4511 (merged 2026-10-30) and #4510; the maintainer accepted that growth on 2026-10-30 and 2026-10-31.

_{Bundled with Rolldown (what Vite ships), brotli q11, decimal KB. A scenario fails only when it is over its brotli cap and its minified size is more than 20 B over the minified recorded with the cap; over the cap within that allowance is brotli layout noise and passes with a warning. Caps and their recorded minified in scripts/size/scenarios.js; the floor and page caps in floor-caps.json are frozen (lower only, or Size-Exception: in the PR body). npm run ratchet lowers caps per RC; it never raises one (scripts/size/README.md).}
