Real-app delegation evidence

Run each app from its own installed checkout with T3CODE_DEV_SEED=0 vp run dev. Use a new synthetic git repository with one empty initial commit, add it with `node apps/server/src/bin.ts project add --base-dir .t3 --title 'Delegation evidence' <repo>`, and enable the chosen provider in the dev app. Never seed from live state.

`driver.py` takes checkout, synthetic project, provider selection, model selection, output directory, action, sample number, and optional variant as positional arguments. Run `prepare` to create an independent parent thread with a completed Ready exchange. Open that exact thread in the web client, wait for Ready, start recording, then run `run`. Keep recording until the parent has reported both A and B results, including automatic completion-wake turns. Do not navigate during a recording.

Samples 1–5 use the identical parallel request with no prescribed launch mode. Sample 6 adds a separate prepared checkout per child, without naming the isolation setting. Sample 7 explicitly forces two wait calls with 10-second timeouts and distinct request ids; it is a transport control, not a test that guidance overrides an explicit request.

The app runs on loopback in a Chromium browser at 1280×800 CSS pixels, light theme, device pixel ratio 2. Workspace identity and composer buttons are hidden for privacy. Transient reasoning identifiers are replaced with [private identifier]. Sample 1's base recording additionally masks a brief reasoning line containing a private identifier. No launch mode, task result, status, or timestamp is redacted. Recordings start on Ready and reach the final results.

`export.py` reads only the supplied development database in read-only mode. It exports messages, relevant tool inputs, launch receipts, child lifecycle timestamps, and child shell commands. Capability catalogs, model selections, provider settings, credentials, and reasoning are excluded. These timelines corroborate the real app recordings; they are not replay fixtures or tests.
