docs(adr): ADR-0037 Live Canvas — draft-overlay live preview while you build - #1694

Conversation
…u build Proposes the split-view Live Canvas: chat on the left, the app rendered from the DRAFT overlay on the right, refreshed per-artifact by the existing stream events — Airtable-class "say it, see it" latency without giving up the ADR-0033 publish gate (what you see is exactly what Publish will make real). Grounded in verified primitives: ?preview=draft reads exist at list+item level (unused by the SPA today), the build stream already names every changed (type,name), and the assistant bus already bridges chat↔host. Four phases: static draft preview → event-driven live refresh → draft DATA preview (in-memory seed overlay, the only new mechanism) → canvas→chat back-channel.

Design proposal for the next big magic-moment iteration: a split-view Live Canvas — chat on the left, the user's app rendered from the draft overlay on the right, refreshing per-artifact while the agent builds/edits.
Design center: Airtable-class "say it, see it" feedback latency without giving up the ADR-0033 publish gate — the canvas renders the staged truth, so what you see is exactly what Publish will make real.
Grounded in verified primitives (file-level table in the ADR):
?preview=draftoverlay reads exist at list + item level — the SPA uses them nowhere today (the gap);draftedenvelopes already name every changed(type, name)in real time;assistantBusalready bridges chat ↔ host (incl. an editor-context primitive for the phase-4 back-channel).Four separately-shippable phases: ① static draft preview (~2–3 d, objectui) → ② event-driven live refresh (~3–4 d, objectui) → ③ draft data preview via in-memory seed overlay — the only new mechanism (~1–2 w, framework) → ④ canvas→chat "change this" back-channel (~3–4 d).
Status: Proposed — open for review; merging records the proposal, not an implementation commitment.
