Playwright + /usr/bin/google-chrome, real web client:
- Added project /home/user/t3code, created thread, selected Codex gpt-6.1-sol.
- Prompt: Reply with exactly: alias verification ready. Do not use tools or change files.
- Provider response: alias verification ready.
- Usage > All environments > Model prices: added alias-verify-a -> alias-verify-b and alias-verify-b -> alias-verify-a.
- Save enabled: true. Click Save changes: Saved, both cyclic mappings retained.

Playwright + system Chrome, real client/server/provider:
- Project and threads created through UI; Codex gpt-6.1-sol responses completed.
- Same two-row cycle: 2 errors, Save enabled: false.
- a -> b -> c acyclic chain: Saved; values retained after full reload.
- c -> a closes saved chain: Save enabled: false.
- Clear a -> b and add c -> a in one batch: Saved; b -> c -> a retained after reload.
- Reverse c -> a into a -> c: blocked until c -> a cleared in same batch, then Saved (video).
- Set custom a price input=1/output=2, map gpt-6.1-sol -> a: real Codex usage breakdown changes to a, custom rates apply.
- Clear gpt-6.1-sol mapping: original model and automatic pricing return.
- Final independent new thread response: verified through the real Codex provider.
No mocks, replay provider, demo data, database fixtures, or source changes.

Explicit comparison ref is this PR's base, because worker snapshot initially lacked origin/main and parent history.

Limitations: Codex account Limits RPC returns JSON-RPC -32600 through local proxy on both main and PR. Cost/token usage works. Native mobile, packaged desktop, macOS/Windows and remote multi-environment UI not exercised.
