Self-host verification

Verified on 27 Sep 2026: fresh clone into a clean directory, api image from docker/api/Dockerfile, compose api with a named volume, direct route to the local Qwen3.8-27B and the running document reader and retrieval services, local signing; torn down after

The rehearsal bundle passed 12/12 in 68 s (the 16-page packet uploaded as files: conflict, gap, pre-existing, copies, cites in the index, reader receipts, record verified and failed when changed; every receipt attested) and the smoke module passed in 17.9 s. The reader and retrieval services were not built from the compose file here: the running ones were used.
