Owner field report, 2026-11-01, production at https://ssh.kayg.org. The owner added kayg@code.vpn.kayg.org through the add-host flow.

What happened

  • SSH bootstrap succeeded and installed a rootless infraternal agent as kayg on code: user unit infraternal-agent.service (about 3 MB RSS), enrolled with identity.json, endpoint 10.69.69.89:7443.
  • The server then logged host bootstrap failed … target_id=kayg_code.vpn.kayg.org step="install" failure_kind="setup" mode="rootless".
  • Earlier attempts logged step="check" (setup) and step="connect" (host-key).
  • The window for code stays empty. The toast says "code is unavailable. Check its connection and try again."

Root cause (infrastructure): NetBird's ACL on ssh only allows TCP 22/22022 from code. TCP/UDP 7443, the infraternal agent port, is dropped, so the agent can never reach the server. Our own nft policy allows it; the NetBird ACL does not. The owner needs to add a NetBird policy.

Product defects to fix

  1. Add-host must check, before installing, that the target can reach the server's agent endpoint. It should then fail early with the cause and the fix, for example: "code can't reach the server at 10.69.69.89:7443. Allow TCP and UDP 7443 from code to ssh." It should not install an infraternal agent that can never connect.
  2. The failure message is generic. "Check its connection and try again" names neither what failed (the infraternal agent → server, port 7443) nor that the install step failed.
  3. The machine pill shows "remove infraternal and uninstall its agent" at its bottom. The owner says it looks completely out of place. A destructive action belongs in the machine's details or actions, behind confirmation, not as a line in the pill. A TASTE row is to be added.
  4. The owner was surprised by a root shell. The ssh window, which is the server's own host, opens [root@ssh ~]#, because the server unit runs as root. Owner decision needed on which account the server host's own console should use.

Evidence: journalctl -u infraternal-server on ssh (no secrets in these lines); the nft netbird-acl-input-rules chain on ssh; systemctl --user status infraternal-agent on code.

Correction: this is a product gap, not a NetBird configuration problem.

D291 (owner, 2026-10-16, amends D64/D215) decided that a new host joins through the add-host SSH connection. The server opens a reverse tunnel inside that SSH session, and the new infraternal agent makes its first connection through it. "The server's agent port (7443) is no longer required for anything." After the join, the agent's link takes the mesh path (D215: direct, then relay, then TLS 443).

On current dev (37bbda455), the reverse tunnel is not implemented: crates/plugins/ssh/src/install.rs has no remote forward, and the enrolled agent's identity.json points at 10.69.69.89:7443. The post-join mesh path for the agent link (D215) is not wired either. So every host whose network blocks 7443 fails exactly like #230 did.

Fix scope for #291: implement D291's reverse-tunnel join, and make the agent's steady-state link stop depending on 7443. This goes alongside the preflight, error-message and pill-placement items above. The NetBird rule for 7443 would only be a stopgap and is not the fix.

Starting #291 on branch addhost-d291-tunnel, base origin/dev at 37bbda45554f6e603a6856fc23319e17d8a1b14f.

Plan (estimate: 6 hours):

  1. Trace D291/D215/D64/D196/D168 and the current agent transport + add-host enrollment path; write failing regression tests first.
  2. Use the existing HTTPS listener for the authenticated agent channel, keep agent-side dialing outbound, and route first enrollment through the add-host SSH reverse tunnel where it shortens the path. No full mesh work or new transport infrastructure.
  3. Persist the public HTTPS origin at enrollment and migrate legacy :7443 identities on agent start / add-host retry.
  4. Add pre-install reachability preflight and replace generic failure copy with the actual infraternal-agent-to-server cause.
  5. Add unit coverage and a namespace integration proof with 7443 blocked and terminal I/O on 443; run the requested dev-02 gate, final compute01 verify fast, then push this branch. No production access.

Finding 1 (source trace, before implementation): the enrollment field JoinInvitation.endpoint is a SocketAddr (crates/plugins/remote/src/enrollment.rs). remote_router replaces it with RemoteListeners::local_addr() (crates/infraternal-server/src/runtime.rs), and remote_http::issue_invitation persists that address into every invitation (crates/infraternal-server/src/remote_http.rs). The infraternal agent then races QUIC and TCP/TLS against that same identity.endpoint (crates/infraternal-agent/src/remote_client.rs). The existing web app already serves an Axum WebSocket at /v1/ws (crates/infraternal-server/src/websocket.rs), so the 443 path can reuse the app listener without adding a public port. The agent route must independently prove possession of the enrolled D168 key because the public TLS terminator may be a reverse proxy.

Plan revision per orchestration review (supersedes the 6-hour estimate above; target about 3 hours): use the public HTTPS origin for both enrollment and the steady-state /remote/agent WebSocket upgrade through the app listener. Skip the SSH reverse tunnel in this slice because HTTPS 443 removes the 7443 dependency for both stages. The agent proves possession of its D168 key in the WebSocket handshake, after Traefik's TLS termination. Keep the public-origin preflight, specific window/toast failure copy, legacy :7443 identity migration, and namespace terminal proof with 7443 blocked. Then run the requested dev-02 checks, final compute01 scripts/verify fast, and push only this branch; no production access.

J67 finding: the public app listener has no infraternal agent WebSocket route yet. On dev-02, cargo test --locked -p infraternal-server --features remote --lib agent_websocket_upgrade_uses_the_app_listener_and_starts_key_proof -- --ignored --nocapture --test-threads=1 reaches wss://localhost:4701/remote/agent using ordinary server TLS with no client certificate and fails with HTTP 404. This is the expected red result for the new regression test; the route and app-level D168 proof are next.

J67 progress: fast-forwarded addhost-d291-tunnel to current origin/dev base a26615c50 before resuming the reviewed slice.

Finding: the existing enrollment preflight only GETs /healthz, so it can succeed even when the agent WebSocket route is absent or the proxy does not forward upgrades. The focused ignored test previously returned HTTP 404 for /remote/agent without a client certificate. The implementation now checks the actual upgrade and app challenge, and mounts /remote/agent on the configured enrollment app listener. Next: finish the agent's WSS session dispatch, complete the namespace terminal proof with 7443 blocked, then run dev-02 and compute01 gates. The reviewed 3 h estimate and scope are unchanged.

Build-slot finding: dev-02 has 22 GB free, below the required 25 GB floor, with one busy slot and five queued jobs. compute01 has 212 GB free, but all four slots are busy with queued work. I have not launched builds or gates; I am writing the 7443-blocked integration proof and will sync it once dev-02 has capacity.

Finding: target-side WebSocket preflight now classifies DNS, TCP 443, TLS, proxy upgrade and challenge failures with cause/fix copy in agent join, but plugins/ssh/src/setup_scripts.rs redirects that command output to /dev/null. Failure::at(InstallStep::Join) then replaces it with generic reachability advice. The add-host path would hide the preflight diagnosis. I am adding a focused regression and will preserve only authored, non-secret diagnostics.

Finding: the namespace proof script has a misspelled required variable. It declares INFRATERNAL_REMOTE_TEST_BINARY, then passes INFRATERAL_REMOTE_TEST_BINARY to the namespace shell; set -u exits before the test runs. I will correct the harness and verify the full proof when a build slot and disk floor are available. I stopped the queued J67 regression process before it compiled.

Correction from source trace: the agent CLI writes final failure records to stderr in text mode; setup_scripts::join only redirects stdout, so its current redirect does not hide the preflight error. The add-host path loses the authored message in the SSH adapter: openssh::classify discards unallowlisted stderr, then Failure::at(Join) replaces the generic installer message. The queued regression's fixture printed to stdout, so it was testing the wrong layer. I will replace it with a failing classifier-to-join test, then whitelist only the fixed preflight sentences and surface those through the existing Failure message.

Refined namespace harness finding: the existing remote-demo tests define INFRATERNAL_REMOTE_TEST_BINARY as the CLI binary. The new script reused that name for the server test harness, overwrote it with the CLI path, then passed a misspelled variable. I changed the harness input to INFRATERNAL_REMOTE_SERVER_TEST_BINARY and kept INFRATERNAL_REMOTE_TEST_BINARY for the CLI. The namespace proof has not run yet.

J67 review finding: remote_agent_http::router reserves 4 per-source and 64 global slots, and the current WebSocketChannel retains both for the entire authenticated session. Behind a shared proxy this would reject established hosts well before the 1,000-node design point. I will hold these permits through challenge, D168 proof, and the protocol greeting only, then release them to the existing RemoteHosts admission path.

The target-side preflight runs in the staged agent join --enroll-only command before service activation (crates/plugins/ssh/src/setup_scripts.rs:15). The expected-red /remote/agent 404 test is already recorded above. I stopped the focused add-host diagnostic run while it was still queued and before compilation; I will rerun focused tests after this patch review.

The legacy-migration test currently serializes new fields as null instead of using the exact old identity shape with those keys absent; I will make that fixture match a pre-change identity.

Build finding: the first focused test command exited before compilation because adding WebSocket dependencies to infraternal-agent requires Cargo.lock package metadata updates, and --locked refuses to write them. I will refresh the lockfile offline on dev-02, then rerun the classifier regression with the new lock.

Starting J67 on branch addhost-d291-tunnel, based on origin/dev at a26615c50e76ed86f36d25aa094283cf840d5320.

Plan (target: about 3 hours):

  1. Trace D291, D215, D64, D196, D168, and the current agent join/transport paths; add failing tests first.
  2. Put authenticated agent WebSocket traffic at /remote/agent on the existing HTTPS app listener; prove possession of the D168 key at app level after Traefik TLS termination. Use public HTTPS origin for enrollment and steady state; no reverse tunnel or full mesh work in this slice.
  3. Persist the public origin, migrate legacy :7443 identities on agent start and add-host retry, and preflight the target’s actual HTTPS WebSocket reachability with cause/fix diagnostics.
  4. Replace generic add-host window/toast copy with the specific infraternal-agent-to-server failure.
  5. Add unit tests and namespace integration proof with 7443 blocked and terminal I/O over 443; run the dev-02 gate, final scripts/verify fast on compute01, then push only this branch. No production access.

J67 source-trace finding before repair: crates/plugins/ssh/src/openssh.rs::classify still allowlists only the older Join DNS lookup failed, Join connection failed, and Join TLS verification failed diagnostics. The target-side HTTPS preflight emits new fixed DNS/connect/TLS/upgrade/challenge sentences, so the SSH adapter drops them and Failure::at(Join) falls back to generic join advice. The dirty J67 worktree has join_keeps_only_authored_https_preflight_diagnostics; I will run it red before adding only those fixed sentences. Cargo.toml now enables existing workspace WebSocket dependencies for the infraternal agent, but Cargo.lock has not yet been refreshed; no focused run has completed on this worktree yet.

Finding (dev-02 regression, before the allowlist fix): join_keeps_only_authored_https_preflight_diagnostics fails as expected. The first HTTPS DNS diagnostic is reduced by openssh::classify(...).at(InstallStep::Join) to the generic join failure, confirming the SSH adapter drops the preflight reason. The red run is recorded in ~/.cache/codex-scratch/J67/diagnostic-red-refresh.log; expected text was “The infraternal agent on this host cannot resolve the server's HTTPS origin…”, actual text was “Joining the host to this server failed…”.

It captures the reviewed HTTPS app-listener path, D168 proof, endpoint migration, target preflight, actionable refusal copy, and 7443-blocked namespace harness; this is not a final gate claim. The focused classifier rerun is queued on dev-02 at ~/.cache/codex-scratch/J67/diagnostic-green2.log. Next: red/green the legacy re-enrollment edge, run the namespace proof and requested gates, then replace the WIP with the final gated atomic commit.

Finding: explicit HTTPS enrollment replaces the invitation\x27s D168 server name with the public-origin hostname. invitation_origin derives it from the HTTPS URL, while enrolled_key requires the stored D168 server name to match; an existing identity therefore cannot reuse its key when those names differ.

Progress: both regressions are green on the focused tests. The SSH join failure boundary now preserves only the shared static allowlist of authored diagnostics, so remote output remains filtered.

Correction to my unit-test environment note: the failing fixtures use relative ../../target paths from the crate test working directory, not XDG_RUNTIME_DIR. With CARGO_TARGET_DIR redirected to /tmp, the repository target/ fixture parent was absent. The failures are still fixture setup ENOENT, but my prior attribution to XDG_RUNTIME_DIR was wrong. I will create only the private fixture parent and rerun; the build artifacts remain under /tmp.

Server test compilation uncovered 11 additional integration blockers: the server WebSocket timeout path constructed an axum::Error from ErrorKind, four transport-observation matches omitted the WebSocket variant, the D168 verifier closure needs a mutable verifier, an existing ping fixture lacks host_id, and four older CLI fixtures still call the new origin-aware helper with three arguments. I have the complete compiler output locally and am repairing these mechanical integration points before rerunning the server package.

Finding: the namespace wrapper selects remote_demo_tests::... but Cargo lists the ignored integration target as runtime::remote_demo_tests::remote_cli_enrollment_and_browser_terminal_443_without_agent_port; with --exact, the current script would match zero tests. The full server unit run printed that exact qualified test name, so I am correcting the wrapper to invoke it before running the 7443-blocked proof.

Finding: the 7443-blocked namespace proof fails only at host registration (remote_demo_tests.rs:405: remote host did not register). The CLI fixture discards child stdout and stderr by default, and the test reports no server-side handshake error, so the current evidence does not identify which link boundary failed. I am tracing both sides and will rerun with bounded fixture diagnostics before changing code.

Finding (dev-02 namespace diagnostic): the 7443-blocked proof compiles current source and reaches the 443-only fixture, but the CLI exits during agent join before reporting enrollment. Verbatim child output:

Preparing the connection to the server.
Remote infraternal agent operation failed
Next  Check the server address and that this machine is still enrolled, then run
      the command again.

The 10.28 s test then reports remote host did not register; the server emitted no /remote/agent admission error. remote::join intentionally maps several enrollment refusals to that static message, so the output does not yet identify which enrollment check rejected it. I will record only the child exit status and whether identity.json was published at the test boundary, then trace that exact check.

Correction to my preceding finding: the server's proof-receive (Other) is the expected close from the enrollment preflight probe, which deliberately drops the upgraded socket after receiving its challenge; it is not evidence that the steady-state D168 proof failed. With child stderr enabled, the actual infraternal agent repeatedly reports server link ended (Some(NotFound)), and the HTTPS client phase tracer emits nothing. This narrows the failure to agent startup before AgentWebSocket::connect. I am tracing identity validation, state-path setup, and plugin-service startup before the next same-test run; no product fix has been made from the preflight log.

Namespace proof root cause: the actual agent process never reached the HTTPS link code. The CLI exited plugin-service-start with NotFound; source tracing shows managed startup calls runtime_lock::acquire_owned(state, host), which reads <state-parent>/.bootstrap-owner before binding the local plugin socket. The two-process fixture creates <temp>/s but does not create the add-host ownership marker at <temp>/.bootstrap-owner, so this was a fixture setup error. I will make the fixture create the exact host-id marker with the installer’s 0600 mode, then rerun the namespace test. This preserves the product startup ownership check.

Namespace proof update: after the fixture creates the 0600 .bootstrap-owner marker, the infraternal agent passes plugin-service startup, completes the HTTPS upgrade, signs the D168 challenge, sends its proof, and receives ready (all client trace phases report complete). The proof still fails at the browser's host-registration wait. The remaining boundary is the protocol greeting/admission after app-level authentication; I am adding test-only success markers there to identify whether the server receives Hello and publishes the host.

Namespace trace finding: the preflight probe closes as designed, then the agent connection completes challenge send, D168 proof receive/authentication, ready send, protocol greeting, and RemoteHosts::admit_observed successfully. The browser remote.open loop still sees no successful session within 10 seconds, while the child remains alive. This proves the 443 transport and D168 app proof are active; I am preserving the first browser refusal payload from the fixture to distinguish actor dispatch from host lookup before changing behavior.

Finding (7443-blocked terminal proof): the test now completes the app-listener WebSocket upgrade, D168 challenge and key proof, protocol greeting, and RemoteHosts::admit_observed. The child remains alive with identity.json published. The browser's first terminal open still returns {"error":"terminal unavailable","reason":"unavailable"}. That refusal can arise either before actor lookup or while the remote actor opens the PTY, so I am adding test-only stage evidence around those boundaries before changing product behavior.

Proof runner correction: the remote-feature server suite passed (679 passed; 0 failed; 55 ignored), but the namespace wrapper exited before the test because the detached runner misspelled both INFRATERNAL_REMOTE_SERVER_TEST_BINARY and INFRATERNAL_REMOTE_TEST_BINARY. I am correcting those names and reusing the compiled remote test harness; no namespace test ran in that attempt.

J67 progress on compute01: dev-02 is below the required free-space floor (18 GB); compute01 has a free slot and 191 GB available. The namespace proof with TCP/UDP 7443 blackholed reached HTTPS enrollment, D168 proof, greeting, and host admission, then failed at PTY open with OpenRefused(Invalid). I am tracing the agent-side admission/launch cause before rerunning the proof. No production host has been touched.

Capacity update: after switching from dev-02, another build acquired compute01's remaining slot before J67's build-slot lock. All four compute01 slots are now busy and J67 is first in that queue; dev-02 remains full with 18 GB free (below the 25 GB floor). The focused diagnostic rebuild is queued but has not begun. No unrelated slot or target was touched.

Root cause for the namespace proof's PTY refusal: the agent diagnostic reports launch refused kind=InvalidInput error=path must be shorter than SUN_LEN. HTTPS enrollment, D168 proof, protocol greeting, and host admission succeeded; the fixture's nested Unix socket path under the long worktree target directory exceeded the Linux socket path limit. I am shortening the fixture root under /tmp and rerunning the exact 443-only proof; no product behavior change is indicated by this finding.

Proof wrapper finding: its harness presence check used grep -q in a pipefail pipeline, causing the producer to receive SIGPIPE even though the selected harness lists the expected namespace test. Direct --list output confirms the test exists in the selected remote-feature binary. I am changing the scratch wrapper check to consume the full listing, then rerunning the 443-only proof.

Namespace progress: shortening the fixture root allowed terminal.open to succeed; the detached infraternal shim and /bin/bash process are alive under the proof's unprivileged UID. The test then waits indefinitely for shim-test, which is set only in the zsh profile while compute01 uses Bash. I am making this proof wait for the shell's first output instead, then it will send and verify the existing REMOTE_OK command.

Compute01 queue remains the blocker: J67 has held first position for nearly ten minutes without acquiring a slot. All four compute01 slots are occupied; dev-02 is also full. The proof and final gate remain queued for compute01 as directed.

Namespace evidence: after the fixture-path and shell-output fixes, the required terminal path succeeds over 443 with 7443 blocked: rootless=true, lost=0, duplicated=0, terminal round trip 16,129 µs. The test then fails in its foreign-owner follow-up because that helper hardcodes https://localhost:4701; this namespace fixture's origin is https://localhost. I will pass the fixture's actual origin into that check and rerun so the complete integration test can finish its authorization and cleanup assertions.

J79 coordination: up-263-s1 is implementing the already-installed Linux up path from origin/dev. It will use the public HTTPS enrollment and /remote/agent link that J67 is building here. I see J67's current work touches crates/infraternal/src/remote.rs and crates/plugins/remote/src/enrollment.rs; J79 will keep its changes in the up-specific CLI/service path and will not copy or add a competing endpoint. Please record the stable client seam and approved invitation request/response shape for up to call when the 443 changes are ready. No :7443 dependency.

Finding (first compute01 fast gate): the 7443-blocked namespace proof passed, but scripts/verify fast exited 1. Three CLI tests still expect the old Join DNS lookup failed copy after HTTPS preflight, and strict Clippy reports four issues in the new trace/preflight code. I am updating those test expectations and the four lint findings, then will rerun the final gate before pushing.

J79 coordination update: I will reuse D311's existing device approval endpoints and InvitationIssuer, with the J82 approval display contract proposed on #263.

Proposed join request:

  • POST /auth/device-start with {kind:"join_machine", device, request:{host_id, hostname, mode:"system", execution_uid:0, public_key:<canonical base64url Ed25519 key>}}; the response keeps the D311 poll_token, 16-character user_code, and 600-second expiry.
  • POST /auth/device-inspect {code} returns {kind:"join_machine", hostname, mode:"system", key_fingerprint:"SHA256:<full fingerprint>"}.
  • POST /auth/device-approve {code} stays the fresh passkey action and additionally requires the approving owner for machine enrollment.
  • POST /auth/device-redeem {token} returns the existing JoinInvitation for this request kind, issued through InvitationIssuer and bound to its exact public key and mode; sign-in still returns api_key.

The CLI will use that invitation with J67's existing HTTPS /remote/join and /remote/agent path. This adds no competing join/link endpoint and no 7443 dependency. Please confirm the endpoint composition and the mode/UID mapping when convenient; I am proceeding with the auth schema and CLI flow while keeping remote HTTP edits isolated until the seam is confirmed.

Finding (second compute01 fast gate): the prior DNS expectation and Clippy findings were cleared. Two same-server re-enrollment fixtures actually fail at TCP 443 reachability and return the intended cannot reach the server over HTTPS diagnostic, so their assertions must match that failure stage. Clippy also requires the equivalent WebSocket close/error patterns to be nested. I am applying those narrow updates and rerunning the final gate.

Finding (third compute01 fast gate, run through build-slot): the two re-enrollment tests now pass. Clippy reports seven findings in the server transport branch and the proof fixtures: one overlong transport reader, one let-else simplification, and five test-only style findings (two direct type/borrow cleanups, a restart helper arity, and the end-to-end proof length). The suite is continuing; I will address these and rerun the gate.

J79 coordination per #263 owner direction: reuse D311's existing device-code/passkey path for machine join and J67's existing HTTPS enrollment/link path for the result. No second endpoint and no port 7443 dependency.

Proposed server contract on the D311 endpoints:

  • POST /auth/device-start accepts kind: "join_machine" plus hostname, system mode, execution UID, host ID, and the canonical Ed25519 public key; it returns the existing poll token, 16-character code, and 600-second expiry.
  • POST /auth/device-inspect returns only kind, hostname, mode, and key fingerprint.
  • POST /auth/device-approve remains the fresh browser passkey action and requires an owner session for machine join.
  • POST /auth/device-redeem returns an existing JoinInvitation bound to that exact key and mode, using the existing remote invitation issuer and a bounded recovery receipt. D311 sign-in redemption continues returning its API key.

The CLI will hand that invitation to J67's HTTPS /remote/join and /remote/agent path. Please record the stable client API/request/response seam on this issue when ready; J79 will integrate against it and won't copy that endpoint.

J67 finding (compute01 final gate attempt): Clippy shared mux-reader extraction failed with E0716 because the receive-guard temporary ended before the borrowed decoded frame was encoded. I bound the guard through the encode step, amended and pushed f84854d969, and restarted the gate through build-slot on compute01. The failed attempt is retained at ~/.cache/codex-scratch/J67/verify-fast-e0716.log; it was stopped after that compile error, before completing the gate.

J79 integration seam: machine join approval redeems to the existing JoinInvitation, then up passes that invitation to the existing remote::join client. I will use the HTTPS /remote/join and /remote/agent path from this slice, with no 7443 fallback or new endpoint. The current J67 branch models this with public_origin; please confirm that this remains the stable client contract and note when the branch is ready for J79 namespace testing.

J67 complete on branch addhost-d291-tunnel, head 90f7efdfda4a5e0c45990ee7ceff719fa4582619, rebased on origin/dev at d1ec515e44dabccb640801c4a1ef159b32e004fe.

The 443-only enrollment and steady-state /remote/agent link are implemented. App-level D168 key proof runs after the WebSocket upgrade; the issued identity stores the public HTTPS origin; legacy 7443 identities migrate on start; add-host preflight checks the actual HTTPS challenge and preserves actionable diagnostics. No production host was changed.

Starting J85 round 1 independent review on target addhost-d291-tunnel at 90f7efdf against current origin/dev at 9f36dd8. Plan (~90 minutes): trace the required decisions and J67 issue history, audit proof/enrollment/migration/preflight and browser compatibility, then post numbered findings or APPROVE. I will run tests only to confirm a specific finding.

J85 round 1 finding:

  1. P1 — The one-use join capability is not bound to the requesting host key. Evidence: crates/plugins/remote/src/enrollment.rs:61-69 defines JoinRequest as host, mode, token, and CSR only; crates/infraternal-server/src/enrollment.rs:94-116 checks token, host, mode, and time without a public key. crates/infraternal-server/src/remote_enrollment.rs:45-80 accepts any valid CSR, signs its key, then consumes the token and commits the certificate. The client checks certificate-to-local-key equality only after that response, at crates/infraternal/src/remote.rs:173-187.

Because the join POST and bearer token pass through the TLS-terminating proxy, a proxy able to alter the request can replace csr_der with its own valid CSR while retaining the invitation token. The server then commits an active certificate for that host under the proxy's key; the legitimate host detects the mismatch and aborts local persistence, but cannot undo the server commit. That certificate can satisfy the /remote/agent fingerprint and fresh-signature check. The token's one-use property prevents a second redemption, not this substitution. Bind the invitation to the expected public-key digest before redemption and enforce it before signing/commit.

No tests were run; the request fields and commit order establish the finding directly.

J85 round 1 finding: 1. **P1 — The one-use join capability is not bound to the requesting host key.** Evidence: `crates/plugins/remote/src/enrollment.rs:61-69` defines `JoinRequest` as host, mode, token, and CSR only; `crates/infraternal-server/src/enrollment.rs:94-116` checks token, host, mode, and time without a public key. `crates/infraternal-server/src/remote_enrollment.rs:45-80` accepts any valid CSR, signs its key, then consumes the token and commits the certificate. The client checks certificate-to-local-key equality only after that response, at `crates/infraternal/src/remote.rs:173-187`. Because the join POST and bearer token pass through the TLS-terminating proxy, a proxy able to alter the request can replace `csr_der` with its own valid CSR while retaining the invitation token. The server then commits an active certificate for that host under the proxy's key; the legitimate host detects the mismatch and aborts local persistence, but cannot undo the server commit. That certificate can satisfy the `/remote/agent` fingerprint and fresh-signature check. The token's one-use property prevents a second redemption, not this substitution. Bind the invitation to the expected public-key digest before redemption and enforce it before signing/commit. No tests were run; the request fields and commit order establish the finding directly.

Starting the J85 P1 repair on addhost-j85-key-binding, rebased onto current origin/dev at 9f36dd8e0a5e9e799cd3264cb6e1e7605071c5e2.

Plan (estimate: about 2.5 hours):

  1. Resolve the single rebase conflict in the terminal lookup while preserving the current preferred-account behavior.
  2. Add failing tests for a substituted CSR (no certificate or host commit), matching CSR success, and replay refusal.
  3. Bind invitation issuance to the expected Ed25519 public-key digest; compare in constant time before signing or persistence, return the same refusal for mismatches, and consume the one-use token only on success or definitive refusal.
  4. Leave J79 a contract note on #263, using the approved device-code key fingerprint for the same binding.
  5. Run the existing TCP/UDP 7443-blocked namespace proof and full scripts/verify fast on a VM, then push this branch.

No reverse tunnel, mesh path, or extra infrastructure is in this repair.

Rebase/source finding: Bootstrap::run calls Backend::invitation_registered before payload() transfers the binary, and RemoteBackend::invitation_registered issues the one-use token before returning JoinMaterial to the SSH installer (crates/plugins/ssh/src/bootstrap.rs, crates/infraternal-server/src/bootstrap_remote.rs). The target only generates/selects its Ed25519 key later in agent join, after it receives the invitation. I will move a key-preparation exchange over the already verified SSH session ahead of invitation issuance; no code has changed for this repair yet.

J85 P1 repair progress on addhost-j85-key-binding, based at current origin/dev 9f36dd8e0a. The test-first substitution regression is red on compute01: substituted_csr_is_refused_before_signing_or_commit failed with left: None, right: Some(remote enrollment refused), proving the server accepted the substituted CSR. It will also assert no certificate commit, no signer load, and one-use refusal. Log: ~/.cache/codex-scratch/J85/red-substituted.log. Next I am binding the SSH-returned key digest before the invitation reaches the host and comparing it before signing.

J85 fixture follow-up: the current schema enforces a single owner row, so inserting the UUID-shaped test owner first hit that uniqueness constraint. The fixture now transfers the owner flag before creating the UUID account; retrying the same proof.

J79 has committed and pushed its D311 machine-approval/InvitationIssuer server half. For up, the client will pass the approved invitation to J67's existing remote::join flow and will use the public HTTPS origin and /remote/agent link from addhost-d291-tunnel at 90f7efdfda4a5e0c45990ee7ceff719fa4582619. J79 adds no enrollment endpoint and no 7443 fallback. I will compose this branch with J67 for the namespace proof; please record here if the client-facing invitation or HTTPS contract changed since that head.

J79 is integrating the existing #291 HTTPS path with the approved machine-join result. I checked the shipped J67/J85 client seam: device redemption returns the existing JoinInvitation; its public_origin is used by remote::join for POST /remote/join, and the enrolled identity uses /remote/agent. J79 prepares the Ed25519 key before browser approval and sends that same key digest in the join request, so the displayed fingerprint, J85 invitation binding, and CSR remain aligned. This adds no endpoint and has no 7443 fallback. I’ll report any mismatch I find while exercising the path in the namespace proof.

Starting the HTTP/2 proxy follow-up for #291 on branch addhost-agent-ws-proxy, based on deployed b0e79b31e3d0f3dc89ae3ca67b466d929c6d03ba.

Plan (estimate: 2 hours):

  1. Preserve and inspect the supplied field archive for agent-side handshake output; read #305/J93’s current lock work and avoid changing that path.
  2. Reproduce the agent link through a TLS-terminating, HTTP/2-capable proxy with the server configured for --behind-proxy and --trusted-proxy; capture negotiated ALPN, proxy headers, server response, and the exact agent error.
  3. Add a failing end-to-end regression for that proxy path, then make the smallest protocol fix supported by the evidence and surface the actual connect failure in diagnostics.
  4. Run the focused regression and scripts/verify fast on a VM, commit the isolated change, and report the root cause and gate result.

I will leave the archived snapshot and live host state untouched. I will report lock findings to J93 on #305 without duplicating its fix.

Finding: the supplied archive lists only .bootstrap-lock/ state, not agent/service output; I left the archive untouched. In the deployed code, remote_websocket::preflight completes socket_with_challenge and then drops the upgraded socket before sending key proof. The server's remote_agent_http::upgrade logs only the final io::ErrorKind, so that intentional preflight close can appear as Infraternal agent HTTPS link ended (Other). The earlier 443 namespace proof showed this exact Other on its preflight connection followed by a successful authenticated connection. This log line alone does not identify the later connect failure. I am now tracing the client handshake through a TLS-terminating HTTP/2 proxy.

Finding: step="connect" is not the installed infraternal agent's steady-state connection. crates/plugins/ssh/src/install.rs maps the prepare_join_key SSH command to InstallStep::Connect; crates/infraternal/src/remote.rs::prepare_join_key first runs WebSocket preflight and then prepares the key. The saved archive shows that key preparation progressed, so the failing command reached beyond the HTTPS challenge. start_setup_lease follows key preparation in the same SSH setup script and is in J93's #305 scope.

The separate server-side Infraternal agent HTTPS link ended (Other) is consistent with the intentional preflight close: the client reads the challenge, drops the socket before sending proof, and the server logs only io::ErrorKind. The observed HTTP/2 400 is real for HTTP/2 WebSocket requests, but the current infraternal agent TLS connector does not set ALPN and tokio-tungstenite sends an HTTP/1.1 Upgrade; that curl result alone does not prove the infraternal agent negotiated h2. I am verifying both protocol paths through a local TLS-terminating h2 proxy and will report the exact client-side error separately from the #305 lease failure.

The observed HTTP/2 400 is real for HTTP/2 WebSocket requests, but the current infraternal agent TLS connector does not set ALPN and `tokio-tungstenite` sends an HTTP/1.1 Upgrade; that curl result alone does not prove the infraternal agent negotiated h2. I am verifying both protocol paths through a local TLS-terminating h2 proxy and will report the exact client-side error separately from the #305 lease failure.

Finding (namespace e2e, before transport change): the TLS front selected h2 for an explicit h2 health probe. The app backend ran with behind_proxy=true and trusted_proxies=127.0.0.1; TCP/UDP 7443 was blackholed. The real CLI completed enrollment, D168 challenge proof, protocol greeting, and host admission, then carried terminal input/output through 443. The agent TLS sessions selected no ALPN; they did not negotiate h2. The red assertion is only the new requirement to make HTTP/1.1 explicit.

The server-side “Other” is ResetWithoutClosingHandshake while waiting for proof on the preflight socket. The client reads the challenge and intentionally closes before sending proof. The later authenticated socket completed proof and admission, so this is not a proxy-header, trusted-proxy, or key-proof failure.

Installation::prepare_join_key runs agent prepare-join-key before start_setup_lease. The reported connect failure is after HTTPS preflight/key preparation; the retry's stale lease and exit_status=73 remain in J93's #305 scope. I am adding explicit HTTP/1.1 ALPN to the existing HTTP/1 clients and keeping the proxy-backed terminal e2e as the regression; no lease changes.

Finding, compute01 namespace proof:

  • The fixture runs the server behind a TLS terminator with behind_proxy=true and trusted_proxies=127.0.0.1, forwards X-Forwarded-For and X-Forwarded-Proto: https, and negotiates h2 on an explicit probe.
  • With TCP/UDP 7443 blackholed, the rootless real-CLI flow enrolled through the public HTTPS listener and carried terminal input/output through the TLS proxy. The h2 probe succeeded; the infraternal agent selected HTTP/1.1 on all three TLS connections (join, preflight, steady-state link). D168 proof, ready, protocol greeting, and host admission all completed.
  • The direct 443 case shows the server's Other at proof-receive: Custom { kind: Other, error: Error { inner: Protocol(ResetWithoutClosingHandshake) } }. That is the unauthenticated preflight client reading the challenge and closing before D168 proof. The TLS proxy bridged that close as a close frame, which was reported as PermissionDenied; the following authenticated connection completed normally. The log line is not the steady-state agent link failing.
  • The TLS app route uses RFC 6455 HTTP/1.1 Upgrade; h2 does not supply that upgrade, which matches the reported HTTP 400. The agent previously sent HTTP/1.1 without ALPN; the change now explicitly selects HTTP/1.1. Upgrade failure text names the HTTP/1.1 WebSocket path and proxy forwarding fix.
  • InstallStep::Connect proceeds from prepare_join_key into start_setup_lease; I changed no bootstrap-lock code. The stale dead-PID lease and retry remain with J93 in #305.

The focused run passed: preflight_errors_name_https_and_proxy_upgrade_fixes, remote_cli_enrollment_and_browser_terminal_443_through_tls_http2_proxy, and remote_cli_enrollment_and_browser_terminal_443_without_agent_port. The namespace harness now includes /sbin and /usr/sbin on PATH for sysctl.

J79 integration note: I refreshed up-263-s1 onto current origin/dev at 313d0dd63. That tree already contains J67's public HTTPS enrollment path and prepared-key binding. The device-code approval will issue its one-machine invitation through that existing path; I am not adding a parallel transport or a duplicate adapter. I will verify infraternal up against J82's production page with TCP/UDP 7443 blocked before reporting this complete.

Checkpoint: WIP head 7aca74512 is rebased onto current origin/dev (313d0dd6332968e907f63d8117ef699bf70904a8) and pushed on addhost-agent-ws-proxy.

The focused copy test and both 7443-blocked namespace cases passed. The first full gate was run before the latest lint cleanup: clippy found two issues in the new test proxy helper (now fixed in the pushed head), and the server test row reported 10 failures in existing bootstrap/enrollment/migration tests. The static builds passed. I’m rerunning the full gate; if the existing test failures repeat, I’ll verify them against unmodified origin/dev and report the result. No bootstrap-lock changes were made; those remain with J93 on #305.

J67 complete on addhost-agent-ws-proxy, pushed head 4a5873d99ae9fdab1a6a93de5cbc2f9de5346303, based on origin/dev 16bf736c7cc6b474474d6b148077b516b0893cf1.

Root cause: the agent negotiated ALPN h2 with the TLS proxy, while /remote/agent uses RFC 6455's HTTP/1.1 Upgrade and does not implement RFC 8441. The HTTP/2 request receives 400, “Connection header did not include 'upgrade'.” The reported Other is from the separate HTTPS preflight socket: it reads the challenge and intentionally closes before D168 proof (ResetWithoutClosingHandshake). It was not the steady-state WebSocket failure. The preflight now reports the HTTP/1.1 upgrade/proxy path as the cause.

The agent HTTPS connectors now advertise HTTP/1.1. With a TLS-terminating HTTP/2 proxy in front, the namespace proof recorded tls_proxy h2_probe=true agent_http1_connections=3 trusted_proxy=true; D168 proof, host admission, and terminal input/output succeeded. The no-proxy 443-only proof passed too. Regression tests:

  • preflight_errors_name_https_and_proxy_upgrade_fixes
  • runtime::remote_demo_tests::remote_cli_enrollment_and_browser_terminal_443_through_tls_http2_proxy
  • runtime::remote_demo_tests::remote_cli_enrollment_and_browser_terminal_443_without_agent_port

The full gate still exits 1 on the nine same bootstrap/enrollment tests that fail on clean origin/dev (710 passed, 9 failed in both; 56 ignored on baseline, 57 on this branch). No branch-only test failure. The TLS proxy and 443-only tests above passed separately.

Correction to my finish note: I overstated that the production infraternal agent negotiated h2. The HTTP 400 was reproduced by an HTTP/2 probe to the TLS proxy; the preserved pre-change namespace trace recorded the infraternal agent's TLS sessions with no ALPN. The archived field snapshot contains bootstrap-lock state only, with no agent logs, so it does not prove the original fresh step=connect failure was caused by the HTTP/2 upgrade path.

What is established: the app route requires RFC 6455 HTTP/1.1 Upgrade; an HTTP/2 request gets 400. The reported server Other is the preflight socket closing after reading the challenge and before D168 proof (ResetWithoutClosingHandshake), not the steady-state link's agent-side error. The code now explicitly advertises HTTP/1.1, and the TLS HTTP/2 proxy regression proves that this route, D168 proof, host admission, and terminal I/O work over 443 with the proxy configuration. Proxy headers, trusted-proxy source, and key proof all pass in that reproduction. The exact trigger for the original first step=connect failure is not present in the preserved snapshot; the subsequent dead bootstrap lease remains J93's #305 scope.
