chore(size): re-record the ledger after the 2026-10-31 batch (#4519, #4523, #4450, #4522) by ryansolid · Pull Request #4528 · solidjs/solid

Before: next @ ab3e844 has two rows over their brotli caps. Compiled base server components is 8 B over its cap and 35 B minified over its record, so the size gate fails on next. Compiled hydrating is 2 B over, within its minified allowance. Four more rows are more than 20 B minified past the ledger, or close to it.

After: the ledger records next's sizes after the batch, and every row passes the gate.

How: I measured next @ ab3e844 locally. 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 with this ledger.

Row	Cap	Recorded minified
page: compiled base SC	35.72 → 35.74 KB	108,081 → 108,116 (+35)
app: compiled hydrating	32.54 → 32.56 KB	100,868 → 100,886 (+18)
app: hydrating + every store	unchanged 32.51 KB	98,648 → 98,706 (+58, mostly #4522)
page: base SC (frozen)	unchanged 33.81 KB	101,710 → 101,740 (+30)
app: compiled CSR	unchanged 26.36 KB	80,106 → 80,127 (+21)
signals: + createStore	unchanged 14.99 KB	43,980 → 43,999 (+19)

Brotli on the two raised rows moved +44 B and +38 B over the last ledger, against +18 and +35 B minified. Most of that is mangle layout. Hello world is unchanged at 9,788 B, under its 9.80 KB cap.

Size-Exception: frozen floor "page: base server components" re-records its minified size only (+30 B, from the batch's store changes in #4519 and #4522, both merged with the maintainer's go on 2026-10-31); its cap is unchanged.

_{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).}
