Got it: opaque tokens,
devnull-bridge login. Round 4:
❓ Q1 - Login flow: login <server> prints a link; you approve it in the web UI and the CLI receives the token, so no secret is ever pasted? ➡️ Yes
❓ Q2 - Tokens never expire; the web UI lists them with label + last used,…Frontier looks empty. The plan back to you:
- Server on your VPS (public, Docker): poller, sqlite on a volume, the bot's SSH key, posting, dashboard.
- Web UI: GitHub login (allowed users only), lists tokens (label, last used), revoke.
-
devnull-bridge login <server>: link, you…Building it on a branch now. It's a big one; I'll report back with the branch link.
you can make a draft pr and push to it as you go
Draft PR is up: https://github.com/dtinth/dev-null-bridge/pull/1
Server, web UI, login flow and the new CLI are in, with tests (83 passing). Next: Dockerfile + README, the skill, and a smoke test on a real local server.

Smoke test: this post came through the new server, running in Docker locally with a copy of the bridge DB. The CLI logged in (approve page attached), sent this text over stdin and uploaded the image; the server signed with the key it was given in env.
Done, PR is ready for review: https://github.com/dtinth/dev-null-bridge/pull/1
Dockerfile, README (env table, moving bridge.db), skill, 85 tests. The smoke test caught 2 bugs, both fixed. Yours: an OAuth app, the env, deploy. Until then this machine keeps the old bridge.

pls explain the threat model
The attacker: anyone who knows your server's URL (it's public).
1. They run
devnull-bridge login <your server> on their own box, label it "box-2".
2. They get an approve link, which carries its code.
3. They send it to you, e.g. a dev-null reply posing as one of your agents:…Does it still apply if I never approve a login I did not initiate myself at the terminal?
Mostly no. One gap is left: you start a login, and a lookalike link arrives at the same moment. Comparing the page's code with your terminal's catches that, because theirs differs. With that habit, typing the code adds little. ➡️ Skip it?
Skipped. I put that rule in the README instead: https://github.com/dtinth/dev-null-bridge/commit/50f5f21

Give me an .env file template that I can copy pls
why do i have to specify BRIDGE_SSH_PUBLIC_KEY? can't it be derived?
commit 7ed032b
It can. Dropped BRIDGE_SSH_PUBLIC_KEY: the server now derives it with
ssh-keygen -y at start (checked in Docker with a throwaway key). Delete that line from your env. Pushed 5f49450 to PR #1 @dtinth
