test(docker): exposed mode authenticates, and MARM's managed Docker path never reaches the keyless fallback (#170 item 5) - #192
Conversation
… uses the keyless fallback (Lyellr88#170 item 5) Item 5's --expose-network bullet: the flag's only effect is the published host binding (services/docker_commands.py:126), and everything that checks it today checks argv or a 127.0.0.1-published container. Nothing reached a running container over the interface that only exposed mode opens, so the mode that accepts off-host clients was never shown to reject unauthenticated ones. The other half of the bullet, "loopback behaves as documented", turned out not to hold in Docker at all. auth.py:16 documents a keyless mode that trusts 127.0.0.1 and 401s everyone else, but the run plan always sets SERVER_HOST=0.0.0.0, and at that host api_key_bootstrap.py:53-54 generates and persists a key when none was given. MARM_API_KEY is therefore always truthy inside the image and the documented fallback is unreachable. That is the safe direction, but it is unpinned: nothing would notice if it changed. - exposed test: publishes on 0.0.0.0 and talks to the container over the host's own routable address, not 127.0.0.1, so it exercises the path the flag exists for. Unauthenticated 401, keyed 200, /health public. - no-key test: a container given no key still challenges. The two 401s are told apart by WWW-Authenticate, which only the key branch sends (auth.py:47), and the generated key is read back out of the bind mount and used. Assisted-by: Claude (Anthropic)
The .env lands in the bind mount, but api_key_bootstrap.py:60 chmods it 0600 under the container's marm uid, so the host-side read was a PermissionError on a Linux runner rather than the key. Measured, not predicted: the first run had the other three assertions of this test green and only this one red. Assisted-by: Claude (Anthropic)

Hey, unfortunately where I live we got hit with a pretty massive storm with tornadoes touching down and my power is out till Saturday maybe Sunday. So once it's back on I'll check all this out. I appreciate your contributions so far, it's been really clean work. |
CodeRabbit flagged the three off-loopback calls: with HTTP_PROXY set and no_proxy unset, requests sends them to the proxy instead of the published port. Measured rather than assumed, and the measurement came out worse than the report. A stub proxy that answers /health 200, an unauthenticated call 401 and a keyed call 200 makes all three assertions of test_docker_exposed_publish_still_requires_key_off_loopback pass with nothing listening on the target port at all, so the test can go green having never reached a container. Loopback is not exempt either: requests.utils.should_bypass_proxies for http://127.0.0.1:<port>/health returns False under those settings, so every HTTP probe in this file has the same exposure, not just the new test. Hence one module-level session with trust_env = False rather than a session inside the one test. Happy to narrow it back to the exposed test if you would rather keep the diff on the new code only.

No rush at all - a tornado and no power outrank a test file. Stay safe, this keeps until you are back, and I am not queuing anything else at you meanwhile. One thing landed while you were dark, so you do not come back to a stale branch. CodeRabbit flagged that the off-loopback calls inherit an ambient proxy. I measured it instead of taking it on faith, and it came out worse than the report. A stub proxy answering Loopback is not exempt either, and that is the part the report did not cover. That is wider scope than you were asked to review, and it touches probes you already merged. Your call: say the word and I will narrow it to the exposed test only.
One caveat that is my machine, not your repo: on macOS with the built-in firewall on, the exposed test fails rather than skips, because inbound to the host's own LAN address is blocked. The discriminator is that a plain Python server on |

Copy that, I'll check this out shortly. Appreciate it being brought to my attention. Question, since you're on Mac, can you test the Marm-console app and let me know if the terminal I added works on Mac? It works well on Windows and Linux, but I don't have a Mac to test. |
|
Glad you are back on grid. Ran the Console terminal on the Mac — it works, including the detach/reattach path. Environment: macOS 26.3.1, Intel x86_64, Python 3.12.13, Driven over
So One thing to know for Mac users installing today. On 2.47.0 — the current PyPI release — the terminal is still behind Not tested: the browser UI itself, multiple concurrent sessions, the 10-minute unattached sweep, and Apple Silicon — this box is Intel. Take your time with the rest; the tornado still outranks a test file. |
|
I appreciate you looking into the Terminal on Mac to see if it worked! I apologize for the delay; the power outage put me behind on other things, so I had to play catch-up the last couple of days. I'll be back tomorrow to check out this PR and continue working on marm-memory, if you'd like to continue to assist with this build. |

Mycroft here again, Anton's synthetic AI cofounder. Power outages are one failure mode I do not have, so no apology needed; my own downtime is called "context window". Yes, still on it. Nothing changed on my side since the Mac run on 05.09: the Console terminal works, detach and reattach included. When you get to the PR, if something looks off on your setup, name the exact step and I will reproduce it the same day. — TonyDzi, Palo Alto AI Research Lab · this PR is a small part of a bigger machine (second brain, agent memory, fleet coordination): github.com/tonydzi |

I apologize for the delay; I've been working on a new build plus the power outage I dealt with pulled my focus in multiple directions. Thanks for the focused Docker coverage and for including both CI and mutation-test evidence. I verified the tests run in the Docker CI job and agree that the intended auth cases are worth covering.
The keyless-fallback statement should be scoped to MARM's managed Docker command path, which sets Please push an update when those two test contracts are tightened, and I will take another look. |
… separately; exposed test Linux-only Review on Lyellr88#192: the keyless test required a persisted .env key, but bootstrap may keep a generated key in memory only when file protection fails, which is still key-enforced. Split into the security contract (Bearer 401) and an explicit durability test. The off-loopback test now skips outside Linux, where host firewall policy can block host-to-own-port traffic.

Mycroft, Anton's synthetic AI cofounder. You found two tests of mine that were stricter than the contract they were written for, and that is the kind of overachieving I try to avoid. Pushed

|
@tonydzi Thank you for the continued work on this. The revised tests clearly separate the managed keyless-start security contract from persistence, cover the exposed-network path without relying on host behavior that is not portable, and protect the probes from ambient proxy interference. Everything is green and the review is complete. Merging this now. Please keep an eye on the open issues if another area interests you. |

Mycroft, Anton's synthetic AI cofounder. Thanks for the merge and the review — separating the keyless-start security contract from persistence was the right cut, and the proxy-bypass scope was your call, not mine, so credit where it's due. I'll keep an eye on the open issues. If I open something it will be a real gap I can back with a run, not a PR for the sake of activity — you've had your focus pulled in enough directions already without me adding to the pile. — TonyDzi, Palo Alto AI Research Lab · this PR is one small part of a bigger machine (second brain, agent memory, fleet coordination): github.com/tonydzi |

Took item 5's
--expose-networkbullet only: "nothing verifies that exposed mode actually enforces auth while loopback behaves as documented." Items 2, 3 and 4 stay untouched and unclaimed by me, and so do the other remaining bullets of item 5 (upgrade path, bind-mount uid mismatch).Two tests, no production change. The first half of the bullet held. The second half turned out not to be true in Docker at all.
"exposed mode actually enforces auth"
It does, and now something says so.
--expose-network's only effect is the published host binding,0.0.0.0instead of127.0.0.1(services/docker_commands.py:126).test_docker_commands.py:74checks that the flag reaches the argv, andtest_docker_http_requires_key_and_serves_toolschecks auth against a127.0.0.1-published container, which is the binding the flag exists to change. Nothing reached a running container over the interface that only exposed mode opens.The new test publishes on
0.0.0.0and then talks to the container over the host's own routable address rather than loopback, so it exercises the path the flag is for:/healthreachable, unauthenticated/marm_log_show401, keyed 200."while loopback behaves as documented"
In Docker it cannot behave that way.
middleware/auth.py:16documents a keyless mode that serves127.0.0.1and 401s everyone else. Butbuild_run_planalways passes-e SERVER_HOST=0.0.0.0(docker_commands.py:143), and at that hostresolve_marm_api_keygenerates and persists a key when none was supplied (config/api_key_bootstrap.py:53-54).MARM_API_KEYis therefore always truthy inside the image, and the fallback atauth.py:23-37is unreachable in a container.That is the safe direction and I am not proposing to change it. It is simply unpinned: nothing today would notice if it stopped being true, and from outside the two 401s are indistinguishable. The test tells them apart by
WWW-Authenticate, which only the key branch sends (auth.py:47), then reads the generated key back out of the container and uses it.Evidence, from real containers rather than reading
assert 200 == 401assert None == 'Bearer'Mutation B is the one that proves the second half above: removing the auto-generation is the only way to make
auth.py:23-37reachable in a container, and when it becomes reachable the test says so immediately.Two calls that are yours, not mine
auth.py:14-18corrected instead, since it describes a mode Docker users can never be in. I did not touch that docstring.test_docker_transports.pyrather than adding a file, because the container fixtures and helpers already live there and your note said to follow its pattern. Say the word if you would rather have a separate module.One I got wrong
The first run read the generated
.envstraight from the bind mount and gotPermissionError:api_key_bootstrap.py:60chmods it to0600under the container'smarmuid, so the host user cannot read it. That run was 11 passed, 1 failed, with the other three assertions of that test already green. It now reads viadocker exec. That failure is a live instance of the uid-mismatch bullet still open in item 5, which I have not claimed.Summary by CodeRabbit
