## Problem ChatGPT Ads appends an `oppref` click id to landing URLs. We don't read it, so ChatGPT ad signups show up in PostHog with no click id and the first-referrer cookie doesn't treat the visit as paid. GROWTH-1278 ## Solution - Add `oppref` to the first-touch click ids sent with PostHog events (`telemetry.tsx`) - Add `oppref` to `CLICK_ID_KEYS` in `first-referrer-cookie.ts`, so it is stored in `_sb_first_referrer` and counts as a paid signal Conversion reporting to OpenAI itself goes through GTM, so it isn't part of this PR. ## Review instructions 1. Run `pnpm exec vitest run first-referrer-cookie` in `packages/common`. The `hasPaidSignals` test now covers `oppref`. 2. On the preview, load any page with `?oppref=test` and check the first-touch event in PostHog carries `oppref`. ## Checklist Check all before review: - [ ] I have read [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) - [ ] If I wrote a new docs topic or edited an existing topic, I used the `/write-the-docs` or `/edit-the-docs` skill, which applies the docs [style guide](https://github.com/supabase/supabase/tree/master/apps/docs/style-guide) Co-authored-by: Joshen Lim <joshenlimek@gmail.com>
