Conversation
The native lane (ci-linux-native.yml) runs scripts/session-e2e.sh directly, without fetching gvproxy or setting MINVMD_GVPROXY_BIN, so every own-IP proof SKIPs at its first gate. Provision the switch once per run, native-only: reuse the host's own prefix, then a staged .scratch/gvproxy, then the pinned fetch-gvproxy.sh. Stage it as gvproxy-min and export both MINIMAL_BIN and MINVMD_GVPROXY_BIN so the daemon finds it and the proofs un-gate. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Exporting MINVMD_GVPROXY_BIN on the native lane un-gated every proof that hardcodes the VM switch's 100.64/16 reserved addresses, while a native minimald runs a per-daemon /24, so NET-003 failed. Signal the native switch with E2E_NATIVE_SWITCH_DIR instead, accepted only by the own-IP and own-IP egress proofs; hand MINIMAL_BIN to the autospawned daemon per call through mnl rather than exporting it; and reuse a gvproxy-min already under the host's own prefix before staging one.

- Line 659: Update the MINIMAL_BIN selection used by the min daemon startup so
that when the caller’s prefix lacks gvproxy-min and provisioning stages the
switch under $WORK/gvproxy-bin, the daemon resolves the staged switch; preserve
caller-prefix behavior when it already contains gvproxy-min.

…efix When the lane exports a MINIMAL_BIN with no gvproxy-min, mnl kept that prefix, so the daemon never saw the staged switch while the native own-IP proofs still un-gated. Override the lane's own prefix, and only leave a prefix a proof swapped in for itself.

Reviewed: 1 finding, none blocking at Address the comments on the diff. Clobber: none: |
The own-IP proofs now run natively when E2E_NATIVE_SWITCH_DIR is set, so a skip names both gates instead of blaming MINVMD_GVPROXY_BIN alone.

…efix The native provisioning probe now follows switch::installed_gvproxy_bin's full chain: a system install (/usr/bin, /usr/lib/minimal/bin, legacy name) sets E2E_NATIVE_SWITCH without a prefix override, so the own-IP proofs run and no fetch or false skip warning happens. A relative MINIMAL_BIN prefix is made absolute, since the proofs cd into a seed dir before calling mnl.

Native gvproxy provisioning reviewed at 4163250. The native lane's own-IP session and egress proofs now run and pass. CI is green, CodeRabbit approved, and the one LOW review finding is deferred to gominimal/inbox#898.

The LOW minimal-review finding (gvproxy fetched twice per native run) is deferred to gominimal/inbox#898. |

…ne (gominimal#1974) * test(e2e): run the expose and listen proofs on the native lane The runtime-publish proofs were gated on MINVMD_GVPROXY_BIN alone, so a native minimald lane — the one the gvproxy provisioning of gominimal#1963 was built for — skipped them. Accept E2E_NATIVE_SWITCH beside it in both gates, the way the own-IP proofs do, and take the box's published address from the daemon's own records (the zone answerer's answer, the expose record) rather than the 100.64/16 constants a VM switch guarantees: the proofs' native arms already read nothing else, so the gate was the only native-lane blocker. VM lanes keep MINVMD_GVPROXY_BIN and are unchanged. * test(e2e): prove min net expose from inside the box end to end Add the expose_from_inside_box case: `min net expose 3000` sent from inside the box by its own helper, every stance end to end. On a native lane the allow stance publishes at the address the daemon's expose record names, the reply and the record agree, and the host probe meets the contract the tree pins for a runtime-only port — bound and listed as (pending; not yet reachable), the relay gate not admitting it, the listener standing inside the box so the refusal cannot be blamed on a dead port (the reach itself is T97's, gominimal#1897). An ask stance routes its dialog to a human attached through a real pty — the request driven from an exec outside the attach, so the dialog on the attached terminal is NET-045's routing — and publishes on their Allow, records nothing on their deny, and fails closed with its own typed error when nobody is attached; a deny box is refused with the stance's own words. Every decision carries its line in the daemon's audit log, asserted and printed beside the leg that produced it. A VM lane asserts the create's typed refusal of allow and ask (T82) and leaves the positive legs to T97. The pty driver gains E2E_PTY_ASK: the ask's dialog renders on the attached terminal exactly as the session-exit prompt does, so it too can only be answered through a real pty; the answer's keystrokes are the daemon's own test driver's (Down then Enter for Allow, Enter for the highlighted Deny). * fix(e2e): read the runtime publish's own record for its address The expose_from_inside_box case read the daemon log for NET-040's attach-time record, but that record is written only for the mappings a create declared — and every box in the case declares none — so on a host where the case runs for real (a CI runner with /dev/net/tun) the polled record never existed and the case failed at its own read; on a host without the device it skipped at the tun gate and passed vacuously. Read the publish's own one-info-line record instead (the session actor's answer_expose line, NET-044's observability) and pin the daemon's filter for the module that writes it, minimald::session, rather than gvproxy_network's. The answered-no negative check grepped the same absent record, so it could never fire; it now asserts the one thing that matters — no published record for the box the human denied. * fix(e2e): probe the recorded address as the URL it is The record's local field is the whole address the forward bound, host and port, and the host probe built its URL by appending the port to it — 127.0.64.21:3000:3000, a URL curl refuses to parse, which would have made the pending-contract probe vacuous: it can only fail, and a gate that wrongly admitted the port would have passed it all the same. Probe the recorded address directly. * fix(e2e): hand the native switch to the daemon the expose cases drive The native lane's staged gvproxy reaches a daemon only through mnl's call-local MINIMAL_BIN, so only a daemon mnl autospawns carries it. The expose cases inherited the daemon proof_hostnames_recover pinned with a bare `minimald run --detach`, which fell back to the system gvproxy path and failed every own-IP box at spawn. Stop the inherited daemon before the first own-IP box in the min net expose and listen-published cases, and force the stop the expose-from-inside case already makes, so mnl autospawns one that carries the switch, as proof_own_ip's first call does. A gvproxy spawn failure at the exec gate now fails naming the switch, never skips as a host that cannot run a sandbox. * fix(scripts): prove the listen publish by reach, not a policy listing The listener watcher commits to the box's publications, never to the runtime-ingress table min session policy lists, so the allow-stance listing check could never pass. NET-016 asks for reach; the peer and host legs prove it. The deny stance still asserts nothing is listed. * fix(scripts): poll the listen close until the refusal stands Until the watcher's next poll withdraws the publication, it accepts the peer's connect and resets it against the closed listener (curl exit 56). The close leg broke on that first reset; it now polls on until the refusal (7) stands, and still fails if the reset outlasts the bound. * test(e2e): carry the listen listing and audit gaps as named known gaps An in-range listen under allow is a dynamic ingress request, so NET-044 owes its row in min session policy and NET-046 its decisions.log line; the watcher writes neither yet. Both checks stay, as KNOWN GAP lines citing gominimal/inbox#912 and counted in the lane summary, and turn into hard assertions when it lands. The close leg logs its time to refusal. --------- Co-authored-by: minimal-foundry[bot] <327719912+minimal-foundry[bot]@users.noreply.github.com>
