J128: free ≥5 KB gzip from the deferred JS class (D188), no cap raise, nothing into critical
Problem: deferred is nearly full on dev (cap 61,440 B gzip / 55,296 B brotli); J92 is 369 B under, J120 432 B, J73b tight, so every UI branch trips the gate.
Branch
perf-deferred-j128, baseorigin/dev7add12640.Plan (estimate 3 h):
*.on-demand.tsbehind thin hooks with idle preload and the latest-position start pattern (J100). Every importer of a moved module must itself be on demand (J106 finding). One atomic commit per move. (1.5 h)scripts/verify fast, push own branch, comment head SHA + gate output. (45 min)Out of scope: raising caps, moving anything into critical, new tooling.
Start: branch
perf-deferred-j128, baseorigin/dev7add12640. Plan and estimate (3 h) are in the issue body. First step: per-module attribution of the deferred class from the bundler metafile.Finding 1: deferred class per module, dev
7add12640(production build on compute01;bun run build && bun transfer-budget.ts).Class totals (gzip): critical 314,939 / 327,680; deferred 59,758 / 61,440 (brotli 52,800 / 55,296); on-demand largest chunk 16,210 / 20,480 (class total 149,640). Deferred = 4 files: chunk-5ps3zgbf 41,609, chunk-nt3hampv 16,668, chunk-n1e9pw11 799, offline.worker 682.
Top 25 deferred modules (est. gzip = the module bytes in its chunk x chunk gzip ratio, from the bundler metafile; identity bytes beside it). No module sits in two chunks, so there is no whole-file duplication; any duplicated helper is inside a file.
Progress (branch
perf-deferred-j128, WIP commits pushed; not yet squashed into final messages)Moved to on-demand chunks, each behind a thin hook, idle preload, first use waits for the chunk and then runs:
windows/split.on-demand.ts: split / new window beside (hook inlifecycle.ts,split-handle.ts; warmed fromcreate.ts)addhost/authority-control.on-demand.ts(+ the inbox card it alone uses): handle keeps the types and the first check stays 1.2 s after creationviews/view-pointer.on-demand.ts: hover card + drag by label; a tap still flies at once, a drag that began before the module arrived continues from the pointer's latest positiontoolbar/palette-rows.on-demand.ts: the palette's rows (open palette is redrawn when they arrive)addhost/mount.on-demand.ts: the Add host glue in product.tsMeasured per commit, production build on compute01 (gzip, cap 61,440 deferred):
| commit | deferred | critical | on-demand largest |
| dev
7add12640| 59,758 | 314,939 | 16,210 || A split | 59,191 (-567) | 314,948 | 16,209 |
| B authority+inbox | 57,404 (-1,787) | 315,009 | 16,211 |
| C view pointer | 56,453 (-951) | 315,029 | 16,219 |
Critical grows 90 B gzip in total although no module moved into it (per-module diff of the critical class between A, B and C is empty): the new on-demand chunks use shared helpers, so the bundler adds names to the critical chunk's export list. Will report it in the final table.
Not moved, and why:
model/journal.ts+operations.ts+reducer.ts(4.4 KB gz):ServerCanvasStore.accept()applies remote layout events through them in order andcurrent()is synchronous, so loading them later would make event ordering asynchronous in the D312 sync path.memory.ts,camera.ts,window-card.ts,frame.ts: per-frame or per-window, needed at first paint.Next: D and F numbers, browser specs for the touched features, first-use latencies.
Finish: head
74d5752387d89b56e3510bd7731f86564fe0f8f3(branchperf-deferred-j128, baseorigin/dev7add12640, 6 commits, treef4cec2e46e). Pushed, not merged.Result: the deferred class is 53,992 B gzip / 48,120 B brotli, down 5,765 / 4,713 B (cap 61,440 / 55,296). Nothing moved into critical (see the note under the table).
7add12640Per commit, deferred gzip (each measured on its own tree): A split 59,195 (-562), B authority + inbox 57,404 (-1,791), C view hover card + label drag 56,488 (-916), D palette rows 54,791 (-1,697), F Add host glue 53,979 (-812).
Critical grew 115 B gzip (311 B identity) although no module entered the critical class: a per-module diff of that class between dev and the head is a few bytes either way (net -13 B in tooltip.ts, +1..+3 B elsewhere). The 6 new chunks import shared helpers by name and the bundler adds those names to the shared chunks' export lists. Brotli critical is 11 B lower. Reported, not hidden; kayg may want to decide whether +115 B gzip on critical is acceptable. I did not find a way to avoid it short of not moving the code.
Gotcha (J106's finding, hit again): my first build of the palette commit moved the whole canvas into the critical class (critical 335,274 B, deferred 36,967 B):
view-pointer.on-demandimportedpalette-rows.on-demandstatically whilepalette.tsfetched it dynamically. Fixed by putting the two row lists they share in a plain module (toolbar/view-windows.ts) that only on-demand code imports. Every importer of an on-demand module is on demand.First-use latency (browser test
test/on-demand-first-use.spec.ts, production build of the preview app on compute01, 300 ms round trip from the latency proxy, VM load 3-14; the module's response is held back, the action is done, then the transfer starts):Not moved, and why
model/journal.ts+operations.ts+reducer.ts(4.4 KB gz):ServerCanvasStore.accept()applies remote layout events through them in order andcurrent()is synchronous; loading them later would make that ordering asynchronous in the D312 sync path. Not worth the risk in a size job.memory.ts,camera.ts,window-card.ts,frame.ts: per frame or per window, needed at first paint.sessions/startup-hints.ts(0.6 KB net): its state is read synchronously by Settings and it has its own test; left for a later round.No module appears in two chunks, so there is no whole-file duplication. Dead code removed:
ViewsModule.dragging()(no caller) and a duplicateACTION_UNLOCK.Browser specs on this head (compute01, the specs of the touched features, 151 tests): 150 pass, 1 fails:
clusters-keyboard-split"holding the key adds no work" (5 stray late frames, limit 4) at VM load average 12.7 on 10 cores. Alternating branch/base runs at the same load: branch clean 9 of 9; base failed 2 of 3 in the one loaded round. Load flake, same on dev. An earlier full run (205 of 206) had onesessions-canvasfetch-count miss that passes 7 of 7 alone with no late script; the two warm-ups with 3 s timeouts now use 1 s.Gate (dev-02,
scripts/verify fast, verbatim excerpt from the log):Static builds row PASS. Cleaned up: Rust target dir removed (below).
