$ t3 project add branch-demo
Added project 1186366e-5569-4ee5-ad0c-056fa7674d1b (branch-demo) at <evidence>/after-062352/branch-demo.

$ t3 thread start branch-demo 'Run git branch --show-current and tell me what branch your session-start git status said. Report both exact branch names. Do not modify any files.' --worktree main --provider claudeAgent --model [configured agent model] --wait
Thread mcp:ea3356e4-f177-4cf0-afa7-fb5cbf823b7e
Both names are the same:

- **`git branch --show-current` now:** `t3/t3/fe21a4a1`
- **Session-start git status said:** `t3/t3/fe21a4a1`

I didn't modify any files.
