# Product Demo Seeding Build a truthful product state before recording pixels. Treat narrative, data, and UI route as one artifact. ## Current-Main Source Gate Product capture represents current Kandev, so old checkouts and old builds are invalid even when their scripts still run. 1. Fetch `origin/main` immediately before capture setup. 2. Create a clean detached capture worktree from `origin/main`; do not reuse the task worktree or a landing branch. 3. Record both SHAs and prove `HEAD` equals `origin/main`. Require an empty `git status --porcelain` before building and before capture. 4. Install dependencies and build frontend/backend from that worktree. Verify it contains `scripts/dev-isolated` and `apps/web/e2e/`. 5. Stage specs, raw masters, configs, proofs, logs, and delivery candidates under a fresh artifact root outside production assets. Reject stale UI, selector, script, or capture choreography until current source is built and the complete route passes rehearsal. Never substitute an old server, cached bundle, or last month's working selectors for this gate. ## Workflow 1. Read `/e2e` and the relevant existing specs/page objects under `apps/web/e2e/`. 2. Write a one-sentence story: user goal, visible action, visible result. 3. Identify separate desktop and native-mobile routes. Mobile must use native mobile surfaces, not a desktop crop. 4. Explore manually with `scripts/dev-isolated --web` when needed. For reproducible capture, use the worker-scoped E2E fixture...
