chore(size): re-record the ledger on next @ 3b7ea81 after the 2026-10-29 batch by ryansolid · Pull Request #4412 · solidjs/solid

ryansolid · 2026-10-29T11:20:56Z

Before: the size check fails on every PR against next. The 2026-10-29 bug-fix batch (#4401, #4397, #4383, #4393, #4406) merged without re-recording the ledger, as the maintainer asked, so next sits over several caps and recorded minified sizes.

After: every cap is CI brotli + 10 B rounded up to 0.01 KB, never lowered, and every recorded minified equals the CI measurement on next @ 3b7ea81. The size check on new PRs measures growth from there.

How: the numbers come from the size job on next @ 3b7ea81 (job 123403325357). Each changed limit: gets a dated ledger line in scripts/size/scenarios.js, and the frozen floors move in floor-caps.json. No source changes.

The biggest moves, in brotli:

signals: + isPending/latest: 10.38 → 11.03 KB. Most of this is fix(signals): latest() opens no transaction for its verdict; its reader watches the seam (#4365) #4393 (+830 B minified over its base) plus fix(signals): an async memo over a verdict memo asks each question once #4397 and fix(signals): latest() of a memo born in a lane throws NotReady, not undefined (#4362, #4363, #4376) #4383.
page: live and live + router: about +0.9 to +1.1 KB, for the same reason.
Hello world (app: compiled floor): 9.93 → 10.07 KB cap, measured at 10,059 B. That is over 10 KB.

Size-Exception: one batch re-record after the 2026-10-29 bug-fix batch, which the maintainer asked for (2026-10-29). The frozen floors that move are the signals core floor (7.44 → 7.53 KB), the app render floor (9.75 → 9.88 KB), hydrating (18.49 → 18.80 KB), page base (33.37 → 33.78 KB) and page live (37.75 → 38.67 KB). Each one is the CI measurement on next @ 3b7ea81 + 10 B.

_{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).}

The CodSpeed dip on createStore setter: delete + set one root key (−14%) is noise. This PR only edits scripts/size/ and no package code changes. CodSpeed also says base and head ran on different runner types. Every other check is green, including the size and floor-caps check.
