Two groups of changes, committed together as the follow-up to the initial push: 1. .gitmodules — submodule Qwen3-TTS now points at the internal Gitea fork (ssh://git@mini-eq:2222/umbragit/Qwen3-TTS.git) instead of upstream GitHub, so a clone actually gets the UmbraAudio branding/integration commit 012e452 rather than vanilla upstream. 2. New infra/ tooling for the cross-machine work in spec 21: agent_bridge, remote_credential_broker (Keychain-backed, secrets read at runtime and generated via read_secret/random_secret — no hardcoded credentials), the enterprise bootstrap scripts, and the oldbox SSH/auth prompts. Plus backup/ restore scripts, two specs (18 UmbraTrans, 19 enterprise control plane), umbraaudio/voices/lmstudio_gate.py, and in-flight edits to the discovery/attribution/profiling modules, config, chapter_builder, emotion, pronunciation, qwen_tts and routes. Also adds *.db to .gitignore: SQLite project databases are runtime state and no .db file was tracked before. Verified before staging: .env's only change is UMBRA_TTS__QWEN_TTS_HELPER_URL and the committed copy has zero secret-looking values; the broker ships only config.example.json.

Commit cadence: commit at least once every Sunday. Never leave a week (let alone a month) of work uncommitted — a single accidental
git checkouton 2026-09-20 wiped out a month of changes toumbraaudio/web/routes.py. SeeAGENTS.md→ Commit Cadence.
scripts/commit_check.sh enforces the nudge: it exits non-zero once the tree has been dirty
longer than a week. The LaunchAgent com.umbraaudio.commitcheck runs it every Sunday at
18:00 and posts a macOS notification when there is uncommitted work.
scripts/commit_check.sh # warn if dirty > 7 days
