 ## Deploy (GitHub Actions is billing-locked: deploy locally)
 
+The hosted deployment lives in the halleluyaholudele@gmail.com Cloudflare account (`c8bea05e04728d860333b91cf095340b`, pinned as `account_id` in `relay/wrangler.toml`). This machine's default wrangler login is another account, so run wrangler for BridgeHook through the `hallelx2` profile: `wrangler-profile hallelx2 <args>` (`~/.local/bin`, a separate login under `~/.config/wrangler-profiles/hallelx2`). Check `wrangler-profile hallelx2 whoami` before deploying. If wrangler 3's requests fail with `fetch failed` while the network works, add `WRANGLER_BIN=<a wrangler 4 binary>` (measured 2026-10-12: v3 failed and v4 deployed).
