+# Vercel / v0 referral signup notes
+
+Date: 2026-07-12
+Target: `https://v0.app/ref/03TUF8` -> redirects into `https://vercel.com/signup/v0?...`
+Script: `C:\Users\User\Downloads\Telegram Desktop\bot_hybrid.py`
+
+## What was changed in the script
+- Set `REF_CODE = "03TUF8"`.
+- Added top-level `HEADLESS` flag.
+- Added `--ref`, `--workers`, `--headless`, `--menu` argparse interface.
+- Removed `sys.argv.append("-n")` because argparse then fails with `unrecognized arguments: -n`.
+- Added Chrome args `--no-sandbox` and `--disable-gpu`.
+- Strengthened form submit fallback from only button/Enter to `form.requestSubmit()` / `form.submit()`.
+
+## Observed runtime behavior
+- Browser successfully opened Vercel signup URL.
+- Email field became visible and accepted the temp-mail address.
+- `Continue with Email` click logged as successful.
+- The page stayed on the email form for 60+ seconds.
+- OTP screen never appeared.
+
+## Important interpretation
+This session did NOT prove the referral flow works end-to-end. It only proved:
+1. navigation works,
+2. email field fill works,
+3. initial submit interaction happens.
+
+It did NOT prove that Vercel accepted the temp mail or actually sent an OTP.
+
+## Likely causes when this exact symptom appears
+- Temp-mail domain rejected silently.
+- Hidden anti-bot/challenge after submit.
+- Frontend accepted the click but backend refused progression.
+- The form needs a different post-submit interaction than the visible button path exposed.
+
+## Recommended next diagnostic pass
+1. Capture DOM text immediately after submit.
+2. Capture screenshot after 5s and 30s.
+3. Log all visible error banners / helper text.
+4. Swap temp-mail provider before changing the browser stack, unless the user explicitly constrained the provider.
+5. Only start OTP polling after positive evidence that the page entered verification state.
+
+## Provider-specific note — mail.tm only
+
+If the user says to use `mail.tm` only for v0/Vercel signup, do not silently fall back to Gmail aliases, AnyMessage, or another temp-mail provider. Probe `https://api.mail.tm/domains` first and log the returned domains.
+
+Observed 2026-07-13:
+- `mail.tm /domains` returned HTTP 200.
+- Only one domain was available: `web-library.net`.
+- v0/Vercel did not progress to OTP with that domain; treat this as a target-side domain rejection or anti-bot block until DOM/screenshot proves otherwise.
+
+Operational rule: when constrained to a single mail provider, report the exact provider/domain status and stop at the verified blocker instead of inventing an alternate inbox path.
+
+## Known good launch note
+SeleniumBase first run may spend time auto-downloading `uc_driver.exe` / `chromedriver.exe`; do not misread that bootstrap noise as app behavior.
