Capture: - Preserve real asset extensions (.lottie no longer truncated); extract the default animation JSON from dotLottie ZIP containers at materialization (minimal built-in ZIP reader, no new deps) - Reset scroll + settle before every viewport snapshot so scroll-linked styles can't bake into captured computed values - Marquee detection now requires content overflow (>1.35x), sustained velocity across separated windows, scroll independence (jiggle test), and genuine content repetition — kills scroll-settle-lerp false positives - Sizing probe trusts authored explicit heights (px/vh/calc) over circular parent/child reflow verdicts, fixing dropped 100vh heroes Normalize/generate: - Canonicalize identity transforms to "none" per viewport; emit explicit transform resets across bands when any band has a real transform - DittoLottie keeps the captured placeholder until DOMLoaded; failed loads no longer blank the container - mx-auto only for true auto-margin centering; literal per-band margins are preserved (fixes full-bleed regressions) - Spacing-scale snap tightened to 0.25px (3.5px stays p-[3.5px]); emit whitespace-nowrap for wrap-vulnerable single-line text leaves - Grid recipes no longer override captured track counts or column spans; responsive re-flow plans apply only when geometry agrees Quality scoring: - Rewritten 6-dimension rubric (payload, decomposition, duplication, semantics, hygiene, runtime) with catastrophe caps and per-dimension reporting; thresholds are documented calibration guides 218 tests pass (74 new), typecheck clean.

ditto.site Compiler
This workspace contains the deterministic compiler used by ditto.site. It captures a source URL, builds a render IR, infers assets/fonts/tokens/sections/recipes/SEO, generates a Next.js App Router app by default or a Vite React app on request, and validates the result with deterministic gates.
The full architecture overview lives in ../README.md. This file keeps only compiler-local commands and notes.
Commands
cd compiler
npm install
npx playwright install chromium
npm run clone -- https://example.com/
npm run clone -- https://example.com/ --serve # then npm install + npm run dev
npm run clone -- https://example.com/ --open # ...and open the browser too
npm run clone -- https://example.com/ --mode=multi --styling=tailwind
npm run clone -- https://example.com/ --mode=single --framework=vite
npm run clone-site -- https://example.com/
npm run validate-site -- ../runs/site-example.com/<timestamp>
npm run clone -- https://example.com/ --mode=multi --concurrency=5
npm run clone -- https://example.com/ --mode=multi --validate --validate-concurrency=3 --viewport-concurrency=2
npm run validate-site -- ../runs/site-example.com/<timestamp> --validate-concurrency=3 --viewport-concurrency=2
npm run bench -- --tier=easy
npm run bench-site
npm run quality -- ../runs/example.com/<timestamp>
npm run audit -- ../runs/example.com/<timestamp>
npm test
npm run typecheck
Root-level scripts forward to these commands, so npm run clone -- <url> works
from the repository root too.
("Clone" here = generating a codebase from a live URL, not git clone; no source
repo required.) On success the CLI prints a copy-paste-safe summary: a single
quoted cd … && npm install && npm run dev line plus safe-to-edit pointers. Pass
--serve to run install + dev automatically, or --open to also launch the
browser. Without --out, a runs/<site>/latest symlink always points at the
newest run so paths aren't timestamp-fragile.
Multi-page generation defaults to the fast no-validation path. Use --validate
when the clone command itself should run the full build/render/gates QA pass, or
run validate-site separately. --concurrency controls source route capture;
--validate-concurrency controls how many routes validation grades at once; and
--viewport-concurrency controls how many clone viewports each route renders at
once.
Generated App Shape
Default Next generated apps use src/app/ditto.css and optional helpers under
src/app/ditto/. Vite generated apps use src/ditto.css and optional helpers
under src/ditto/, with multi-route pages under src/routes/. Validation builds
keep data-cid attributes for source/clone alignment; delivered apps strip those
validation ids and keep only required data-ditto-id anchors.
