# Independent proof audit reproduction: R03

Reviewed [#32866](https://git.cafe/pingdotgg/t3code/pull/32866), requested head [7d37139923](https://github.com/pingdotgg/t3code/commit/7d371399233f867230e75d07138409b736b4f002).

Detached fresh checkout at [b088b88d19](https://github.com/pingdotgg/t3code/commit/b088b88d19fb0edc43f754da2e1d199bda70d6d8). No production server/contracts difference from this revision to requested head; only test typing changed under apps/packages.

Used the uploaded setup.py, hang.py, foreign.py, extra-instrumentation.py and driver.mjs, changing only local paths and the assigned loopback port. Ran `vp i`, then started `T3CODE_DEV_SEED=0 T3_REPRO_HANG_DARK=1 T3_CAPTURE_CONTROL=<scratch>/control-after vp run dev:server --home-dir /home/user/wt/pr-32866-audit-2/.t3`. Issued isolated auth, seeded synthetic fixture threads, ran C1. No live T3 home was read or used.

UTC steps/results:
- 12:03:00.344 appearance sent with dark action held.
- 12:03:15.898 appearance returned the exact 15000ms timeout text in delivered R03.
- 12:03:17.403 owner snapshot sent; 12:03:17.816 returned the exact delivered busy result, including structured error.
- 12:03:17.404 owner waitFor sent; 12:03:17.860 returned the exact delivered busy text.
- 12:03:19.998 status sent; 12:03:20.034 succeeded, while the appearance gate remained held.
- All request.start records used one server-browser connection, ff6ef6e7-f2f7-4130-99b7-17d70ffe7c58.
- 12:03:22.757 close sent; 12:03:22.868 succeeded. Encoder/page/context closure milestones followed, and healthy B evaluate succeeded.

Compared the first owner appearance/snapshot/waitFor result JSON objects directly against the delivered R03 AFTER transcript: exact equality, without normalizing result text or error fields. Status success and retained host connection also match. Generated ids and timestamps differ as expected. No agent-visible behavioral discrepancy.

Full C1 driver output, sanitized setup/server/provider logs, emitted server milestones, and the adjusted reproduction scripts are in this archive. Credentials and private runtime model strings are redacted; synthetic identities remain for correlation. The provider is a local fixture and invokes no model.

AI-assisted; verified with the tests and tools listed above.
