Tier: Fix first · Order: 6 of 35 · Effort: S · Impact: med

What

The editor stops stuttering every 30 seconds while you're idle.

Why

Audit: every autosave re-exports every page's HTML on the main thread (useWhpApi.ts:78-160), even with no changes. Lag is the #1 complaint about every builder.

Today

Unconditional 30s interval; full export each time.

Design notes

Skip when not dirty; cache exported HTML per page so unchanged pages cost nothing.

Depends on

  • #30 Honest save state and publish gated on save

From the 2026-10-07 site-builder research (competitor review, user sentiment, code audit, Fable prioritization). Roadmap: https://claude.ai/artifact/QpQcSCk21z6SN7LPSm8tKE · id idle-autosave-skip
