Injected ongoing draft appears in All Orders list with amber Ongoing chip.

⚠ Mid-Gate-2 lessons

CF auto-deploy stalled silently on the initial push. Last deploy was hours before; pushing the empty commit 4f02144 retriggered it. Wrote feedback_verify_cf_worker_deploy_landed.md to capture the check (wrangler deployments list from nix-cafe/) — companion to the existing feedback_auto_deploy_on_push.md rule (don't manual-deploy).
Wasted ~3 hours running npm run deploy locally before checking memory. Existing feedback from 2026-04-21 said exactly: "ran npm run deploy inside nix-cafe, piped through tail -40, which hid output and looked hung for minutes — blocked the session for no reason." Ignored my own saved lesson.
SQL inject escape gotcha — embedded JSON payloads (cafe.draft_orders.payload jsonb) mangle through bash → node -e → knex.raw nested quotes. Switched to a temp .mjs script with parameterized knex.raw(?, [...]) per the existing project_prodsql_escape_limits reference.
page.reload after open-shift — revalidatePath doesn't always propagate fast enough on cold Workers. Explicit reload guarantees SSR picks up the new session.
X close button only renders when tabs.length > 1. Discard-modal test had to first add a +New tab so the close X on the ongoing draft is rendered.
