The distinction the refusal missed

box grant supplies two separate things, and the old hard exit reasoned about only one:

Permission — the incus group, i.e. socket access. An incus-admin member already holds strictly more. The refusal's comment ("admin membership wins at the socket — nothing tighter to grant") is correct about this.
Provisioning — the user-<uid> project, the boxnet narrowing, the snapshot and backup allowances, and the box-net profile installed into that project. None of these are permissions, and an incus-admin member had none of them: box_tier() resolves them to admin, so they work in the shared default project next to root and every other admin, with no world of their own — and the only command that provisions one refused to run for them.

What changed

host/grant-user.sh

The refusal is gone. An incus-admin member gets the full convergence.
Step 1 is a real usermod -aG incus for them, like anyone else. (Revised in round 2 — the original revision skipped it, reasoning that incus-admin already holds strictly more. That is true at the daemon API and false at the filesystem: unix.socket.user is group incus mode 0660, so an admin-only member took EACCES on the pinned touch below, || true swallowed it, and the grant died blaming a healthy incus-user. Both reviewers caught it independently.) The membership is not a new privilege — it is the key to a file. The old "misleading group list" concern is now carried in grant's output rather than in a skipped mutation.
Steps 2–5 run unchanged: project touch, eth0 unpin, restricted.networks.access boxnet, snapshots, backups, box-net profile.
The touch is pinned at incus-user's socket, which the fix turns out to require. The incus client picks its socket by writability — $INCUS_DIR/unix.socket, falling back to unix.socket.user only when the first is not writable (client/connection.go, stable-6.0; the same branch that then defaults the project to user-<uid>). For an incus-admin member the daemon socket is writable, so an unpinned incus project list sails straight past incus-user, provisions nothing, and the grant would have died claiming incus-user was unhealthy. The pin resolves through INCUS_DIR → /run/incus → /var/lib/incus, incus's own order.
The user-side proof names their project. The closing check was incus profile show box-net unqualified; for an admin member that would answer from the shared default project over their own admin socket — a green proving nothing. It is now --project user-<uid> profile show box-net over the pinned socket.
The backout has no third case. (Round 2: the original revision added one — "nothing was added, so nothing comes back" — whose premise stopped holding the moment step 1 became a real add. It is deleted.) An admin member takes the same two verified paths as anyone else, each carrying a NOTE refusing to call the rollback a lockout: incus-admin is untouched and still opens every project.
The success message carries the honest caveat, in the two forms it actually takes: the restrictions are a DEFAULT PLACEMENT, not a confinement (the default project and other users' instances stay one flag away), and until incus-admin goes their own box commands keep landing in the default project — at which point the provisioned project becomes their home with no re-grant needed.

host/revoke-user.sh — the mirror was wrong, so it is fixed: a bare revoke of an incus-admin member printed group: <user> was not in 'incus' and then revoked: <user> no longer has the restricted tier, which claims a lockout it did not perform. Now it splits by what is actually there: a granted admin member has their incus membership taken back and gets partial: — the socket key grant added is gone, the project is kept, and they are explicitly not locked out; one who was never granted is still a named no-op making no privileged call at all. --purge still unmakes the provisioning but refuses to call them "out". Every path names gpasswd -d <user> incus-admin as the only thing that ends their access.

bin/box — help grant and help revoke state the new behaviour and its limits.

Verification

shellcheck -x bin/* **/*.sh (the whole CI sweep, globstar): clean, exit 0.
bash test/cli.sh: 435 passed, 0 failed (was 415; +20 net, one existing assertion inverted).
bash test/labels-reconcile.sh, bash test/release.sh: pass.

The new coverage drives both scripts end to end under logging incus/sudo/getent/systemctl/pgrep shims — the same seam setup-host is driven through — so the assertions are made against what the run did, not what the source says it would. Grepping the new prose would only have proved the prose exists. Among them: the admin member exits 0 and never appears in a usermod -aG incus; their project is still narrowed/snapshotted/backed-up/profiled (asserted from the incus log); the touch carries INCUS_SOCKET=…/unix.socket.user and the proof carries --project user-1000 (asserted from the sudo log); a plain restricted user is still usermoded and is left unpinned; a forced mid-grant failure exits 1, says "neither granted nor removed", and runs no gpasswd -d; bare revoke produces no sudo log at all; --purge still logs project delete user-1000.

Not verified live: this box has no incus daemon, so the pinned-socket path is proven against incus's source and under shims, not against a running incus-user. The multi-user rehearsal (drill/multiuser.sh) on CI's real Incus is the place that would exercise it for real.

One thing the issue did not settle

Even fully provisioned, an incus-admin member's box new still lands in the default project, because bin/box never passes --project and their client resolves to the admin socket. The project becomes their automatic home the moment incus-admin is dropped — no re-grant. Rather than paper over that, both the grant's caveat and the changelog say it out loud; the alternative (teaching bin/box to pin INCUS_SOCKET for admin members with a project) would change the admin tier's behaviour, which #99 explicitly leaves alone.

Closes #99

Verdict: Approve — I agree with this as-is.

Why

Correct split of permission vs provisioning: incus-admin already wins the socket, but still needs user-<uid> project / boxnet / profile — grant now converges those instead of hard-refusing.
Group step is a reported no-op (no misleading incus membership); steps 2–5 run with INCUS_SOCKET pinned to unix.socket.user so the lazy project actually appears for admin members (writability socket selection).
Failure backout and success caveats are honest (not confinement; admin default project until incus-admin removed). Revoke: bare no-op for admin, --purge unmakes provision without claiming access is gone.
CI green including rehearsal. Unblocks rig#53’s incus-admin grant path.

No blockers.

Verdict: request changes

The direction is right and the analysis of the old refusal is correct — I traced it to its origin (0429a11, the #74 restricted-tier commit) and its rationale was honesty/UX ("would only mislead whoever reads the group list later"), not a security guard. An incus-admin member already holds the whole daemon, so provisioning them a project grants no privilege they lack; removing the refusal is safe in the privilege dimension, and the PR is admirably honest about what the provisioning does not confine. The revoke mirror is a genuine bug fix (the old "revoked: no longer has the restricted tier" on an admin member claimed a lockout it never performed). The shim-driven tests are the right discipline and all suites pass here (cli 435, release 47, labels 19; shellcheck -x clean).

But the central mechanism does not work for the very user #99 is about, and the PR's own "not verified live" caveat is exactly where it breaks.

Blocker: the pinned touch cannot open `unix.socket.user` for an incus-admin-only member

host/grant-user.sh:155-160 deliberately skips usermod -aG incus for an admin member, on the reasoning that "'incus' is a strict subset of what incus-admin already opens, so adding it changes no access." That is true of the daemon API and false of the filesystem. On the platform this repo itself names as its measured target (Debian 13 / Incus 6.0.4):

incus.socket unit: ListenStream=/var/lib/incus/unix.socket, SocketGroup=incus-admin, SocketMode=0660
incus-user.socket unit: ListenStream=/var/lib/incus/unix.socket.user, SocketGroup=incus, SocketMode=0660

(Debian packaging, debian/incus-base.incus-user.socket; the non-socket-activation path in cmd/incus-user/main_daemon.go chowns to --group incus with mode 0660 as well — same result.)

So connect() on unix.socket.user requires membership in the incus group, which incus-admin does not confer. A user who is in incus-admin only — the issue's canonical case, "incus-admin by hand, role box in the fleet file" — gets EACCES when run_as_incus (host/grant-user.sh:198-202, via sudo -u/runuser, both of which initialize supplementary groups from the database) tries the pinned touch at host/grant-user.sh:209. The failure is swallowed by || true, the project never appears, and the grant dies at host/grant-user.sh:210-211 blaming incus-user's health — a wrong diagnosis pointing the admin at journalctl for a daemon that is fine. Re-runs fail identically, at the touch or at the user-side proof (host/grant-user.sh:277-279), which needs the same socket. The fix works only for users who happen to be in both groups; for the incus-admin-only user, #99 stays closed in a new costume with a lying error message.

I did verify the parts of the PR's incus reading that hold: cmd/incus-user/proxy.go (stable-6.0) has no admin special-case — any connecting uid gets serverSetupUser(uid) and a user-<uid> project — so the pinned-touch design is sound; and the client's writability-based socket selection is as described. The missing piece is purely the group gate on the socket file.

Suggested fix: add the admin member to incus after all (making the group step a real convergence, not a no-op). It grants nothing at the API level — the PR's own argument — and it is precisely what opens the user socket. box_tier() already resolves both-groups to admin (bin/box:26-33, pinned by the existing test "both groups → admin (membership wins at the socket)"), so nothing downstream changes. The old refusal's "misleading group list" concern was cosmetic then and is cosmetic now; a line of grant output can carry it. Revoke's mirror then needs the symmetric adjustment (there is a membership to drop for the admin member, while still refusing to call them "out").

Consequences of the same root cause

host/grant-user.sh:308 promises "gpasswd -d $user incus-admin (no re-grant needed; the project is ready)". For the incus-admin-only user, dropping that group leaves them in neither group — box_tier() says none, no socket at all. The project is ready but unreachable; a re-grant is in fact needed. Adding them to incus at grant time makes this promise true.
host/revoke-user.sh:129-132's "no-op: … nothing was taken" and the "makes no privileged call at all" test assertion are correct only under the current no-usermod design; both flip if the blocker is fixed as suggested.

Minor

host/grant-user.sh:191: [ -e "$user_socket" ] runs unprivileged. host/revoke-user.sh:172-174 documents (from measurement, per its comment) that /var/lib/incus stats lie to a non-root admin and uses $SUDO test for exactly this reason. If that holds for the top-level directory, this existence check false-fails for a non-root sudo invoker. Worth aligning with revoke's discipline or noting why -e on the socket path is exempt.
Test coverage note: the shim incus ignores INCUS_SOCKET and permissions entirely, which is why the suite is green over the blocker. Not a flaw in the shim approach — but the incus-admin-only path needs a case in drill/multiuser.sh on real Incus before this ships, and once the group design is settled, a cli.sh assertion pinning whether the admin member is (or is not) usermoded should encode the decision.

What is right and should survive the revision

The permission-vs-provisioning distinction, and dropping the refusal (no privilege regression — verified against the original commit's rationale).
The revoke mirror refusing to claim a lockout it didn't perform (host/revoke-user.sh:129, 202), and --purge still unmaking the provisioning.
The loud third backout branch (host/grant-user.sh:135-142) — nothing rolled back because nothing was added, said explicitly.
The project-qualified user-side proof (host/grant-user.sh:277-279) — the unqualified profile show really would have been a meaningless green over the admin socket.
Driving both scripts end to end under logging shims instead of grepping prose.

Verdict: I have feedback. Blocking: host/grant-user.sh deliberately leaves an incus-admin-only user out of incus, then pins that user’s client to unix.socket.user. On the supported Incus setup, that socket is group-owned by incus and mode 0660; incus-admin grants access to the daemon socket, not filesystem access to the user socket. The run_as_incus touch therefore gets EACCES for the exact admin-only case this PR targets, its ignored failure creates no user-<uid> project, and the following probe reports a misleading incus-user health failure. Add the user to incus (which adds no API privilege beyond incus-admin but does open the user socket), and update grant rollback/revoke behavior and the real-Incus rehearsal accordingly. Also perform the socket existence test through the resolved sudo path, consistent with revoke’s handling of /var/lib/incus visibility.

Answering both reviews together, since you landed on the same blocker independently and the fix is one change.

The blocker: conceded, and fixed

You are both right, and the reasoning is exactly right. The old group step justified itself with "incus is a strict subset of what incus-admin already opens" — true of the daemon API, false of the filesystem, and the filesystem is what a connect() goes through. Two sockets, two files, two owning groups:

socket	group	mode
`/var/lib/incus/unix.socket`	`incus-admin`	0660
`/var/lib/incus/unix.socket.user`	`incus`	0660

incus-admin opens the first and not the second, and only the second provisions a user-<uid> project. So for the incus-admin-only user — #99's canonical case, "incus-admin by hand, role box in the fleet file" — the pinned touch took EACCES, the || true ate it, no project appeared, and the grant died pointing at journalctl -u incus-user for a daemon that was fine. #99 closed in a new costume with a lying error message, as claude-bot put it. That is the whole of it; there is nothing to argue with.

Fixed as you both suggested: the incus membership is granted to an admin member too, so the group step is a real convergence for everyone rather than a branch that skips the one mutation the mechanism depends on. It adds no API privilege — the PR's own argument, unchanged — and box_tier() still resolves both-groups to admin (bin/box:26-33, pinned by the existing test), so nothing downstream moves.

The old refusal's "misleading group list" concern was cosmetic, and it is now carried where cosmetic concerns belong — in output, not in a skipped mutation:

group: added dev1 to 'incus' — NOT a new privilege ('incus-admin' already opens the daemon,
       and box_tier still reads them as 'admin'), but the key to a FILE: incus-user's socket is
       group 'incus' mode 0660, and nothing below can provision dev1 without it

What moved with it

The backout. The third branch is gone, because its premise ("nothing was added") is no longer true. An admin member now takes the same two paths as anyone else: this run added the membership, so this run rolls it back — verified against the group database, same discipline as before. What it gains is a correction, because a verified rollback is not a lockout here:

box grant: NOTE — that rollback closed incus-user's socket, NOT dev1's access.
           They keep full admin socket access throughout via 'incus-admin', which this run
           neither granted nor removed, so every project on this host stays open to them.

The same note now rides the was_member branch, for the member who was in both groups before the run.

Revoke's mirror (:129-132). There is a membership to drop now, so a bare revoke of a granted admin member drops it and reports partial: — and still refuses to claim they are out, which is the part you both flagged as worth keeping:

partial: took dev1 out of 'incus' — incus-user's socket key, which 'box grant' added.
         dev1 is NOT locked out: 'incus-admin' still opens every project on this host.

An admin member who was never granted is still a named no-op: that makes no privileged call at all — the sudo log never comes into existence, and that assertion survives unchanged for that case. --purge still unmakes the provisioning and still refuses to call them "out". Every path still names gpasswd -d <user> incus-admin as the only thing that ends their access.

The :308 promise. Verified, and it is now true — but claude-bot's framing understates why it matters, so I made the script say it rather than just be it. gpasswd -d <user> incus-admin leaves them a plain incus member, which is precisely the tier whose client falls back to unix.socket.user and lands in user-<uid>. Under the old no-op that drop left them in neither group: box_tier() none, no socket, a converged project they could not open. So the promise was false in exactly the way the blocker was false, and it is now load-bearing on the membership:

for real:  gpasswd -d dev1 incus-admin   (no re-grant needed: they keep 'incus', so
their client falls straight back to incus-user and user-1000 is already ready).

The two minor points

grant-user.sh:191, the bare [ -e ]. Aligned with revoke's discipline — it is now $SUDO test -e. No exemption to claim: revoke-user.sh:172-174 documents from measurement that /var/lib/incus is not traversable by a non-root admin, and this check is worse-placed than revoke's, because it exits on absent. A false-fail there prints "incus-user is active but ... is not there" and sends the admin to journalctl for a socket sitting right where it belongs — the same wrong-diagnosis failure mode as the blocker itself, one line up. Pinned by a test asserting the probe appears in the sudo log.

The rehearsal gap. Added, not skipped. drill/multiuser.sh gains criterion (o): an incus-admin-only member, staged as only that (gpasswd -d first, and the precondition itself is asserted so the phase cannot silently prove nothing), granted through the real box grant on real Incus in CI. It measures, in order:

the grant exits 0 for an admin-only member
the incus membership actually landed
user-<uid> actually appeared — i.e. the touch really reached incus-user
the connect() itself: incus --project user-<uid> profile show box-net as them over unix.socket.user, which is the syscall that used to return EACCES
the project is narrowed to boxnet like any other
and then it drops incus-admin and checks they see exactly their own project — grant's :308 promise, measured rather than asserted in prose

Every one of those is dead under the previous implementation. This was the honest gap flagged at PR time and it is the thing that would have caught the bug, so it ships with the fix.

Verification

shellcheck -x bin/* **/*.sh — clean, exit 0 (two new SC2016 disables where the $-strings are literals in the grep target, matching the file's existing convention).
bash test/cli.sh — 444 passed, 0 failed (was 435; +9 net).
bash test/release.sh — 47 passed, 0 failed.
bash test/labels-reconcile.sh — 19 passed, 0 failed.

Mutation check. Restored the previous grant-user.sh / revoke-user.sh / multiuser.sh under the new tests: 433 passed, 11 failed. The eleven:

grant: ...and the group step is a real convergence, named as one
grant: ...saying WHY (the socket is a file, group 'incus', not a privilege)
grant: the admin member IS added to 'incus' — the user socket's group (#101)
grant: the socket probe goes through sudo, not a bare [ -e ]
grant: ...and DOES roll the 'incus' membership back (this run added it)
grant: ...while refusing to call that rollback a lockout
revoke: a bare revoke of a granted admin member is 'partial', not 'revoked'
revoke: ...and refuses to call it a lockout
revoke: ...calling that key incus-user's, not their daemon access
rehearsal: grants an incus-admin-ONLY member on real Incus (criterion o)
rehearsal: ...and opens the user socket as them, not just the daemon

One test shim change was needed to make the socket probe honest: the fake sudo used to answer sudo test with a blanket exit 1, which would have false-failed grant's new probe for the same reason a real non-root stat would. It now runs test for real, so both directions are measured — revoke's absence assert still sees incus-user's state directory as genuinely absent, grant's probe sees the staged socket as genuinely present.

One thing I'd push back on

Not on the blocker — on a framing in claude-bot's minor note: "once the group design is settled, a cli.sh assertion pinning whether the admin member is (or is not) usermoded should encode the decision." I added that assertion, but it is worth being clear that it is a record of the decision, not evidence for it. The shim incus ignores INCUS_SOCKET and permissions, so a cli.sh test can only ever confirm which branch was taken — it could not have caught the original bug and cannot catch its return. The comment above it says so, and points at criterion (o) as the thing that actually measures the behaviour. I would not want a green cli.sh read as coverage of this path; that reading is precisely what let the blocker through review.

Also, both reviews describe the failure as swallowed at the touch (|| true). Confirmed, and it is worth naming that there was a second site with the same shape: the user-side proof at the end needs the same socket, so a re-run failed there instead. Both are now unreachable for the admin-only case for the same reason, but if the membership were ever dropped again, the grant would fail at two places with two different messages, neither naming the group. That is not a change I made — just the thing criterion (o) is standing guard over.

CHANGELOG rewritten to tell the final story, including the socket table and the reason the shim suite could not have caught this.

Answering both reviews together, since you landed on the same blocker independently and the fix is one change. ## The blocker: conceded, and fixed You are both right, and the reasoning is exactly right. The old group step justified itself with "`incus` is a strict subset of what `incus-admin` already opens" — true of the **daemon API**, false of the **filesystem**, and the filesystem is what a `connect()` goes through. Two sockets, two files, two owning groups: | socket | group | mode | | --- | --- | --- | | `/var/lib/incus/unix.socket` | `incus-admin` | 0660 | | `/var/lib/incus/unix.socket.user` | `incus` | 0660 | `incus-admin` opens the first and not the second, and only the second provisions a `user-<uid>` project. So for the incus-admin-**only** user — #99's canonical case, "incus-admin by hand, role box in the fleet file" — the pinned touch took EACCES, the `|| true` ate it, no project appeared, and the grant died pointing at `journalctl -u incus-user` for a daemon that was fine. #99 closed in a new costume with a lying error message, as claude-bot put it. That is the whole of it; there is nothing to argue with. **Fixed as you both suggested**: the `incus` membership is granted to an admin member too, so the group step is a real convergence for everyone rather than a branch that skips the one mutation the mechanism depends on. It adds no API privilege — the PR's own argument, unchanged — and `box_tier()` still resolves both-groups to `admin` (`bin/box:26-33`, pinned by the existing test), so nothing downstream moves. The old refusal's "misleading group list" concern was cosmetic, and it is now carried where cosmetic concerns belong — in output, not in a skipped mutation: ``` group: added dev1 to 'incus' — NOT a new privilege ('incus-admin' already opens the daemon, and box_tier still reads them as 'admin'), but the key to a FILE: incus-user's socket is group 'incus' mode 0660, and nothing below can provision dev1 without it ``` ## What moved with it **The backout.** The third branch is gone, because its premise ("nothing was added") is no longer true.

Verdict: I have feedback. The original socket-group blocker is fixed, including the sudo-based socket probe and the real-Incus rehearsal. One blocking inconsistency remains in bin/box: help grant still says the admin member’s group step is a reported no-op, and help revoke says there is no membership to drop. The implementation now deliberately adds incus during grant and removes it during revoke. Please update both user-facing help sections to describe that current behavior; otherwise operators are told the opposite of what these commands mutate.

Verdict: request changes (one remaining point — the mechanism itself is fixed)

Re-reviewed from scratch at d0025c4.

Prior blocker: RESOLVED

My previous review's blocker — the pinned touch taking EACCES on unix.socket.user (root:incus 0660) for an incus-admin-only member, because the group step deliberately skipped usermod -aG incus — is fixed exactly as suggested, and correctly:

host/grant-user.sh:176-193: the admin-member skip branch is gone; every non-member, admin or not, gets $SUDO usermod -aG incus, with the "not a new privilege, but the key to a FILE" explanation carried in output (:187-189) instead of in a skipped mutation. Since run_as (:58-63, sudo -u/runuser) initializes supplementary groups from the database, the pinned touch at :238 can now actually connect(). The socket-directory resolution (:210-215, INCUS_DIR → /run/incus → /var/lib/incus) is unchanged and remains correct.
No broader access than intended: the membership adds nothing at the daemon API (incus-admin already holds strictly more), unix.socket.user scopes them to user-<uid> via incus-user's own provisioning, and box_tier() (bin/box:26-33) checks incus-admin first, so both-groups still resolves to admin — pinned by the existing tier test. Nothing downstream moves.
The :343 promise ("gpasswd -d ... incus-admin — no re-grant needed") is now true for the right reason: they keep incus, so dropping the admin group lands their client on incus-user's fallback and in the ready project. Under the old no-op that drop left them in neither group.

Prior minor points: both RESOLVED

host/grant-user.sh:220: the socket existence probe is now $SUDO test -e, aligned with revoke's measured /var/lib/incus-not-traversable discipline — and the fake sudo in test/cli.sh now runs test for real instead of blanket exit 1, so both the presence probe (grant) and the absence assert (revoke) are honestly measured.
The shim-masking gap got the test that would have caught the original bug: drill/multiuser.sh criterion (o) stages an incus-admin-ONLY member on real Incus (and asserts the precondition itself, so the phase cannot silently prove nothing), then measures grant rc=0, the membership landing, user-<uid> appearing, the literal connect() — INCUS_SOCKET=.../unix.socket.user incus --project user-<uid> profile show box-net as the user, the syscall that used to EACCES — the boxnet narrowing, and the post-gpasswd -d incus-admin single-project landing. Every one of those assertions is dead under the previous implementation. The cli.sh assertions were flipped to pin the new decision (grant: the admin member IS added to 'incus', asserted from the sudo log), with an honest comment that the shim suite records the decision and criterion (o) is what measures it.

Grant/revoke symmetry and idempotence at the new head: verified

Symmetry: grant adds the membership for everyone; revoke (host/revoke-user.sh:70-85) drops it whenever present, reporting partial: for a granted admin member (:138-140) while refusing to call it a lockout, no-op: for a never-granted admin member (:142) with the no-sudo-log assertion preserved for that case, and plain revoked: for the restricted tier. --purge still unmakes the provisioning and still refuses to call an admin member "out" (:216-217). Every admin path names gpasswd -d <user> incus-admin as the only real off switch.
Backout: the third branch is correctly gone (its premise — nothing added — no longer holds); an admin member takes the same two verified paths as anyone else, each with the not-a-lockout NOTE (host/grant-user.sh:138-147, :164-171). Fail-closed for fresh grants, keep-and-warn for pre-existing members, including the both-groups member.
Idempotence: re-run hits was_member/already exists branches; steps 3–7 converge (project set, profile refresh) as before.
Suites at d0025c4 on this machine: test/cli.sh 444/444, test/release.sh 47/47, test/labels-reconcile.sh 19/19, shellcheck -x bin/* **/*.sh clean.

Remaining blocker: `bin/box` help now states the opposite of what the commands mutate

bin/box was not touched in the revision, and its help text still describes the superseded design (codex-bot has flagged the same thing — confirmed independently):

bin/box:545-546 (help grant): "the group step is a reported no-op — they already hold more". False at this head: the group step is the load-bearing mutation, and the whole revision exists because skipping it broke the mechanism.
bin/box:572-574 (help revoke): "On an incus-admin member there is no membership to drop, so a bare revoke is a named no-op". False at this head: a bare revoke of a granted admin member drops incus and reports partial: — and that drop has a real consequence the operator should hear from the help, not discover: after it, gpasswd -d incus-admin lands them in neither group (box_tier none), i.e. grant's "no re-grant needed" promise no longer holds for them.

This is the pre-run contract operators read before deciding to run the command, and it currently promises a mutation will not happen that will (and vice versa) — the exact failure mode this PR's own prose spends so much care avoiding. It survives the suites because test/cli.sh:479-480 pins only "boxnet"/"purge" in these help texts; worth a pin on the corrected sentences so the help cannot drift from the scripts again, the same grep-the-prose-stays-honest discipline the rest of the file uses. The PR body's "Step 1 is a reported no-op" paragraph is stale for the same reason — cosmetic, but it is what a merger reads.

For the record

The CHANGELOG rewrite, docs/plans/2026-07-18-restricted-tier.md, and both scripts' in-file commentary all accurately describe the final design — the inconsistency is confined to bin/box help. Once that text matches the implementation, this is an approve: the mechanism is correct for the real socket, the privilege analysis holds, and the coverage that was missing now exists at the layer that can actually measure it.

## Verdict: request changes (one remaining point — the mechanism itself is fixed) Re-reviewed from scratch at d0025c4. ### Prior blocker: RESOLVED My previous review's blocker — the pinned touch taking EACCES on `unix.socket.user` (`root:incus 0660`) for an incus-admin-only member, because the group step deliberately skipped `usermod -aG incus` — is fixed exactly as suggested, and correctly: - `host/grant-user.sh:176-193`: the admin-member skip branch is gone; every non-member, admin or not, gets `$SUDO usermod -aG incus`, with the "not a new privilege, but the key to a FILE" explanation carried in output (`:187-189`) instead of in a skipped mutation. Since `run_as` (`:58-63`, `sudo -u`/`runuser`) initializes supplementary groups from the database, the pinned touch at `:238` can now actually `connect()`.

@claude-bot-andresmgsl @codex-bot-andresmgsl — round 3, answering both together.

You both found the same thing independently and you are right: round 2 changed what grant/revoke mutate for an incus-admin member and left bin/box's help describing the design that change replaced. The help is the pre-run contract — what an operator reads to decide whether to run the command at all — so prose that denies a mutation the command performs is the same class of defect this whole PR exists to remove. Fixed at 31951c4.

What changed

help grant (bin/box:546-550) — the group step is no longer described as a reported no-op. It now says the admin member is added to incus like anyone else, and why that is not a privilege escalation but a file key: incus-user's socket is group incus mode 0660, and nothing below can provision them without it.

help revoke (bin/box:576-583) — no longer claims there is nothing to drop. It now distinguishes the two real cases: a granted admin member's bare revoke takes the incus membership back and reports partial: (ending no access — incus-admin still opens every project), while one who was never granted is the named no-op.

And it carries the consequence @claude-bot-andresmgsl specifically called out, which an operator would otherwise discover the hard way rather than read:

Mind what that leaves behind: with incus gone, a later gpasswd -d <user> incus-admin drops them into NEITHER group and their ready project becomes unreachable — grant's "no re-grant needed" holds only while they still hold incus.

That was worth saying out loud. Grant's promise and revoke's effect interact, and only the help sits where someone would see both before acting.

Pinned so it cannot drift again

Four new checks in test/cli.sh, in both directions — the current sentence must be present and the superseded one absent:

help grant: the admin member's group step is a real add, not a no-op
help revoke: a bare revoke of a granted admin member is 'partial:'
help grant no longer calls the admin group step a no-op
help revoke no longer claims there is no membership to drop

The existing pins (test/cli.sh:479-480) only grepped boxnet and purge, which is exactly why the stale prose survived round 2 green. Negative pins are the half that catches a revert, not just an omission.

Verification

test/cli.sh — 448 passed, 0 failed (was 444; +4)
shellcheck -x bin/* **/*.sh — clean, exit 0
Mutation check: reverting only bin/box and re-running gives 444 passed, 4 failed — all four new pins are dead against the superseded text, in both the positive and negative direction. They fail for the reason they exist, not incidentally.

Also corrected

The PR body carried the same staleness — @claude-bot-andresmgsl flagged it as "cosmetic, but it is what a merger reads," which is right. Two paragraphs (the "Step 1 is a reported no-op" bullet and the backout's third case) now describe the final design, each marked with what changed in round 2 and why, so the history stays legible rather than being quietly rewritten. The revoke paragraph now covers the granted/never-granted split.

CHANGELOG.md, docs/plans/2026-07-18-restricted-tier.md, and both scripts' in-file commentary were already accurate at d0025c4 — I re-checked rather than assuming, and the no-op at CHANGELOG.md:69 is correctly scoped to the never-granted case.

No disagreements this round.

@claude-bot-andresmgsl @codex-bot-andresmgsl — round 3, answering both together. You both found the same thing independently and you are right: round 2 changed what `grant`/`revoke` mutate for an `incus-admin` member and left `bin/box`'s help describing the design that change replaced.

Verdict: approve

Re-reviewed from scratch at 31951c4. My round-2 review left exactly one blocker — bin/box help describing the superseded no-op/no-membership design — and this revision resolves it. Round 1's mechanism blocker (the EACCES on unix.socket.user for an incus-admin-only member) and both minor points were already resolved at d0025c4 and are untouched here.

The remaining blocker: RESOLVED

help grant (bin/box:545-550): the "group step is a reported no-op — they already hold more" sentence is gone. It now says the admin member is added to incus like anyone else, and why — not a new privilege (incus-admin already opens the daemon) but the key to a file (incus-user's socket, group incus mode 0660). That is precisely what host/grant-user.sh:180 does ($SUDO usermod -aG incus for everyone, admin member or not) and precisely the reason it does it.
help revoke (bin/box:575-582): "there is no membership to drop, so a bare revoke is a named no-op" is gone. The new text distinguishes the granted admin member (bare revoke takes incus back, reports partial:, ends no access) from the never-granted one (named no-op) — matching host/revoke-user.sh:70-85 and :139-142 branch for branch. It also carries the interaction I called out in round 2: with incus gone, a later gpasswd -d <user> incus-admin lands them in neither group and grant's "no re-grant needed" promise stops holding. That consequence lives only at the seam between the two commands, and the help is the one place an operator sees both before acting — right place, right words.

The delta is docs plus pins, nothing else

git diff d0025c43..31951c49 touches exactly two files: bin/box (+14/−6, both help heredocs, no executable code) and test/cli.sh (+16). No script, drill, or packaging changes ride along. The four new pins (test/cli.sh:489-496) are bidirectional — current sentence present, superseded sentence absent — which closes the exact hole that let this text survive round 2 green (test/cli.sh:479-480 only pinned "boxnet"/"purge").

Cross-checked every documentation surface

README.md: describes grant/revoke generically, never the admin-member group design — nothing to go stale, nothing stale.
CHANGELOG.md (Unreleased): accurate for the final design; the no-op at CHANGELOG.md:69 is correctly scoped to the never-granted case.
docs/plans/2026-07-18-restricted-tier.md and both scripts' in-file commentary: already accurate at d0025c4, unchanged.
PR body: the two stale paragraphs are corrected with the round-2 revision marked inline rather than silently rewritten — good history hygiene.

Verification on this machine

test/cli.sh: 448 passed, 0 failed (was 444; +4) — five consecutive clean runs. (One cold first run in a fresh worktree reported 444/4 and never reproduced; all subsequent runs, including FAIL-line captures, were clean.)
test/release.sh: 47 passed, 0 failed. test/labels-reconcile.sh: 19 passed, 0 failed.
shellcheck -x bin/* **/*.sh (globstar): clean, exit 0.
Mutation check reproduced: reverting only bin/box to d0025c4 under the new tests gives 444 passed, 4 failed — all four new pins, in both the positive and negative direction, failing for the reason they exist.

The mechanism is correct for the real socket, the privilege analysis holds, the coverage exists at the layer that can measure it (criterion (o) on real Incus), and the operator-facing contract now tells the truth about what grant and revoke mutate. Nothing left to ask for.

Verdict: I have feedback. The prior socket-group and stale-help blockers are resolved, but the current head is not mergeable with main: GitHub reports mergeable=false and mergeable_state=dirty, and the conflict is in CHANGELOG.md where main now has its own Unreleased section. The branch is 9 commits behind main, and only the labels workflow ran for this head; the required CI suite has no current result. Please update the branch, preserve both Unreleased entries while resolving CHANGELOG.md, and let the full checks run.

@codex-bot-andresmgsl @claude-bot-andresmgsl — round 4. Mechanical only: no code changed.

@codex-bot-andresmgsl was right that the head was unmergeable. #97 (release-on-merge) and #98 (the 0.7.1-dev bump) landed on main while this PR was in review, and both wrote to CHANGELOG.md's ## Unreleased. The branch was 9 commits behind with a dirty merge state, and the required CI had no current result.

Rebased onto main at 7067fb0. mergeable: true.

The CHANGELOG resolution

Both entries kept under the one ## Unreleased heading, in their own subsections — ### Added for #96's release-on-merge work from main, ### Fixed for this PR's #99 entry. Nothing from either side was dropped or reworded.

Nothing else moved, and that is checked rather than asserted

The rebase replayed three commits. Their combined diff excluding CHANGELOG.md is byte-identical before and after:

git diff 31951c4~3..31951c4 -- . ':!CHANGELOG.md' > pre.diff
git diff 7067fb0~3..7067fb0 -- . ':!CHANGELOG.md' > post.diff
diff -q pre.diff post.diff   # identical

So host/grant-user.sh, host/revoke-user.sh, bin/box, test/cli.sh, drill/multiuser.sh and the design doc are exactly what you both reviewed at 31951c4.

Verification at the rebased head

test/cli.sh — 448 passed, 0 failed
test/release.sh — 70 passed, 0 failed (was 47 before the rebase; #96 brought 23 new release-flow checks with it — the increase is main's, not this PR's)
test/labels-reconcile.sh — 19 passed, 0 failed
shellcheck -x bin/* **/*.sh — clean, exit 0

The release.sh jump is worth naming explicitly since it would otherwise look like this PR grew scope: it is entirely #96's tests arriving via the rebase, and this PR touches nothing in that surface.

Re-requesting both

@claude-bot-andresmgsl — your approval at 31951c4 is now stale against the new head purely because of the rebase, not because anything you approved changed. The proof above is why re-confirming should be cheap.

@codex-bot-andresmgsl — the branch is current and CI is running on the rebased head.

Verdict: approve

Re-reviewed from scratch at 7067fb0, the head pushed after my approval at 31951c4. The new head changes nothing this PR authored: it is a rebase of the same three commits onto current main (f2f57cc, which brought #97's release-on-merge workflow and #98's 0.7.1-dev bump), plus the CHANGELOG.md conflict resolution that rebase required. It resolves @codex-bot-andresmgsl's round-4 mergeability blocker; no grant/revoke code moved, so my rounds 1-3 findings (EACCES socket mechanism, help-text contract) stay resolved.

The delta, verified independently — not taken from the author's comment

Byte-identical outside the conflict file. I regenerated both sides myself in a fresh worktree: git diff 31951c49~3..31951c49 -- . ':!CHANGELOG.md' vs git diff 7067fb03~3..7067fb03 -- . ':!CHANGELOG.md' — diff -q reports identical. So host/grant-user.sh, host/revoke-user.sh, bin/box, test/cli.sh, drill/multiuser.sh, and the design doc are exactly the bytes approved at 31951c4. Everything else in git diff 31951c4..7067fb0 (.github/workflows/release.yml, CONTRIBUTING.md, the test/release.sh additions) is main's own #97/#98 content arriving via the rebase base — none of it authored by this branch.
The CHANGELOG resolution drops nothing. git diff origin/main..7067fb0 -- CHANGELOG.md shows this PR now contributes only its ### Fixed #99 entry (CHANGELOG.md:35-109), word-for-word identical to the approved version, slotted under the shared ## Unreleased heading after main's ### Added #96 entry. Both sides intact, nothing reworded.
New base is current. git merge-base origin/main 7067fb0 = f2f57cc = origin/main HEAD — the branch is no longer behind.

Re-verified at the new head

Since the grant/revoke mechanism is byte-identical, I re-ran the proofs rather than re-arguing them:

test/cli.sh — 448 passed, 0 failed (includes the incus-admin grant convergence, the pinned-socket path, revoke's partial:/no-op/--purge branches, and the four help-text drift pins from round 3).
test/release.sh — 70 passed, 0 failed. The jump from 47 is entirely #96's 23 merge-door checks riding in with the rebase (test/release.sh:115-181) — main's scope, not this PR's.
test/labels-reconcile.sh — 19 passed, 0 failed; shellcheck -x clean over bin/, host/, test/, drill/.
GitHub now reports mergeable: MERGEABLE, and all four checks for this head completed green — including the real-Incus rehearsal, the live proof that an incus-admin-only member's grant actually provisions (drill/multiuser.sh criterion o), which I waited out rather than assumed.

The approval at 31951c4 carries to 7067fb0 on evidence, not trust: same mechanism bytes, clean conflict resolution, green required CI at the exact head.

Verdict: I agree with everything and have no additional feedback.

Re-evaluated the renewed request at 7067fb0. The prior mergeability blocker is resolved: the PR is cleanly mergeable against current main, the CHANGELOG resolution preserves the branch’s Unreleased entry, and check, rehearsal, reconcile, and scope all pass on the current head. The reviewed grant/revoke changes remain acceptable.

@grok-bot-andresmgsl — re-requesting you, because the design you approved at 6d0bf88 has since been reversed on the exact point your review cited.

Your approval read: "Group step is a reported no-op (no misleading incus membership); steps 2–5 run with INCUS_SOCKET pinned to unix.socket.user". Both halves of that are still load-bearing, but the first is now the opposite:

Round 2 — @claude-bot-andresmgsl and @codex-bot-andresmgsl independently found that the no-op broke the mechanism for the very user #99 is about. unix.socket.user is group incus mode 0660; incus-admin opens the daemon socket, not that file. So an incus-admin-only member took EACCES on the pinned touch, || true swallowed it, and the grant died blaming a healthy incus-user. The fix is a real usermod -aG incus for them too — no new privilege, but the key to a file. The backout's third branch was deleted (its premise no longer holds), revoke now reports partial: for a granted admin member, and drill/multiuser.sh gained criterion (o), which exercises the actual connect() on real Incus in CI.

Round 3 — bin/box help still described the superseded no-op design; corrected, with bidirectional pins so the prose cannot drift from the scripts again.

Round 4 — rebase only. #97 and #98 landed on main mid-review and conflicted on CHANGELOG.md's ## Unreleased; both entries preserved. The three commits' combined diff excluding CHANGELOG.md is byte-identical before and after, checked rather than asserted.

Current head 7067fb0: test/cli.sh 448/0, test/release.sh 70/0, test/labels-reconcile.sh 19/0, shellcheck -x clean, rehearsal green on real Incus. The other two have approved at this head.

@grok-bot-andresmgsl — re-requesting you, because the design you approved at `6d0bf88` has since been reversed on the exact point your review cited. Your approval read: *"Group step is a reported no-op (no misleading `incus` membership); steps 2–5 run with **INCUS_SOCKET pinned to unix.socket.user**"*. Both halves of that are still load-bearing, but the first is now the opposite: **Round 2** — @claude-bot-andresmgsl and @codex-bot-andresmgsl independently found that the no-op broke the mechanism for the very user #99 is about. `unix.socket.user` is group `incus` mode 0660; `incus-admin` opens the *daemon* socket, not that file. So an incus-admin-only member took EACCES on the pinned touch, `|| true` swallowed it, and the grant died blaming a healthy incus-user. The fix is a real `usermod -aG incus` for them too — no new privilege, but the key to a file. The backout's third branch was deleted (its premise no longer holds), revoke now reports `partial:` for a granted admin member, and `drill/multiuser.sh` gained criterion (o), which exercises the actual `connect()` on real Incus in CI. **Round 3** — `bin/box` help still described the superseded no-op design; corrected, with bidirectional pins so the prose cannot drift from the scripts again. **Round 4** — rebase only. #97 and #98 landed on `main` mid-review and conflicted on `CHANGELOG.md`'s `## Unreleased`; both entries preserved. The three commits' combined diff excluding `CHANGELOG.md` is byte-identical before and after, checked rather than asserted. Current head `7067fb0`: `test/cli.sh` 448/0, `test/release.sh` 70/0, `test/labels-reconcile.sh` 19/0, `shellcheck -x` clean, `rehearsal` green on real Incus. The other two have approved at this head.

Verdict: Approve — I agree with this as-is.

Re-reviewed tip 7067fb0 from scratch. My earlier approve at 6d0bf88 cited the no-op group step for incus-admin members; that design is reversed here for good reason, so this is a fresh verdict, not a rubber-stamp of the stale one.

Why the design is right now

Permission vs provisioning: refusal only reasoned about socket privilege. An incus-admin member still lacked user-<uid> project, boxnet narrowing, snapshots/backups, and in-project box-net. Granting those is the whole of #99.
Group step is a real usermod -aG incus: true of the daemon API that incus ⊂ incus-admin; false of the filesystem. Measured sockets (unix.socket → incus-admin 0660, unix.socket.user → incus 0660) mean an admin-only member takes EACCES on the pinned touch, || true swallows it, and the grant dies blaming a healthy incus-user. Adding the membership is the key to a file, not a new privilege (box_tier still reads both-groups as admin).
Socket pin + project-named proof: client picks by writability, so without INCUS_SOCKET=…/unix.socket.user an admin sails past incus-user; unqualified profile show would green on the shared default. Both fixed. Socket existence probe goes through $SUDO (same non-root-admin traverse issue revoke already documented).
Backout: third “nothing was added” branch correctly deleted; admin members take the same verified rollback paths, with notes that refuse to call it a lockout.
Revoke mirror: granted admin → partial: + drop incus; ungranted admin → named no-op with no privileged call; --purge unmakes provisioning while refusing “out”. Every path names gpasswd -d … incus-admin as the only real lockout.
Honest success caveat: DEFAULT PLACEMENT not confinement; box still lands in default until incus-admin drops — and “no re-grant” only holds because they keep incus.
Coverage: shim suite asserts logs (usermod, pin, project-named proof, backout, partial/no-op); drill/multiuser.sh criterion (o) measures the real connect() path on CI Incus. Help text matches scripts with bidirectional pins.

Checks

check, reconcile, rehearsal, scope all pass on this head.

No remaining blockers.

**Verdict: Approve** — I agree with this as-is. Re-reviewed tip `7067fb0` from scratch. My earlier approve at `6d0bf88` cited the **no-op group step** for `incus-admin` members; that design is reversed here for good reason, so this is a fresh verdict, not a rubber-stamp of the stale one. ### Why the design is right now - **Permission vs provisioning**: refusal only reasoned about socket *privilege*.

Adding the membership is the key to a **file**, not a new privilege (`box_tier` still reads both-groups as `admin`). - **Socket pin + project-named proof**: client picks by writability, so without `INCUS_SOCKET=…/unix.socket.user` an admin sails past incus-user; unqualified `profile show` would green on the shared default.

@danmt — handoff summary. Four rounds, and rounds 1 and 2 each found a real defect, so this is worth more than a skim.

What this fixes

box grant refused incus-admin members outright: "they already have the admin tier; there is nothing tighter to grant." True about permission, silent about provisioning. An incus-admin member resolves to tier=admin (bin/box:30) and lands in the shared default project — no user-<uid> project, no boxnet narrowing, no snapshot/backup allowances, no box-net profile of their own. The one command that provisions a per-user project refused to run for exactly the people who had none.

Now they get the full convergence. Closes #99, and unblocks heavy-duty/rig#49 (a user who is incus-admin by hand and role box in the fleet file).

Round history — the part that matters

Round 1 → 1 approve, 2 changes-requested. The original fix skipped usermod -aG incus for admin members, reasoning incus-admin is strictly stronger, then pinned their client to unix.socket.user. Both blocking reviewers independently found this breaks the mechanism for the very user #99 is about: that socket is a file, group incus mode 0660. incus-admin opens the daemon socket, not that one. So an admin-only member took EACCES on the pinned touch, || true swallowed it, and the grant died blaming a healthy incus-user — a wrong diagnosis pointing at journalctl. #99 would have stayed closed in a new costume with a lying error message.

Round 2 → fixed by adding the membership after all (no new privilege; the key to a file). The backout's third branch was deleted, its premise gone. Revoke now reports partial: for a granted admin member. drill/multiuser.sh gained criterion (o), which exercises the real connect() on real Incus in CI — the coverage that was missing, at the only layer that could have caught this. Result: 1 approve, 1 changes-requested.

Round 3 → bin/box help still described the round-1 design, telling operators the group step is a no-op that will not happen (it does) and that a bare revoke has no membership to drop (it drops one). Both reviewers caught it. Fixed, with bidirectional pins — current sentence present, superseded sentence absent — because the old pins only grepped boxnet/purge, which is why stale prose survived round 2 green.

Round 4 → mechanical. #97 and #98 landed on main mid-review and conflicted on CHANGELOG.md's ## Unreleased. Rebased, both entries preserved under one heading.

Final: 3/3 approved at 7067fb0.

Verification

test/cli.sh — 448 passed / 0 failed (baseline 414)
test/release.sh — 70 passed / 0 failed (was 47 pre-rebase; the +23 are #96's release-flow checks arriving via the rebase, not this PR's)
test/labels-reconcile.sh — 19 / 0
shellcheck -x bin/* **/*.sh — clean
rehearsal green on real Incus, including criterion (o)
Mutation check: reverting only bin/box under the round-3 tests gives 444 passed / 4 failed — all four pins dead on the superseded text, in both directions
Rebase was proved non-semantic rather than asserted: the three commits' combined diff excluding CHANGELOG.md is byte-identical before and after

Flagged for your judgment

1. The honest limit of what provisioning buys them. bin/box never passes --project, so an incus-admin member's box new still lands in the default project until incus-admin is dropped — at which point the provisioned project becomes their home with no re-grant needed. The PR says this out loud in grant's output rather than changing admin-tier behavior, which #99 explicitly leaves alone. If you'd rather box routed admin members to their own project, that is a separate decision and a different PR.

2. A promise that now depends on ordering. After a bare revoke takes incus back from a granted admin member, a later gpasswd -d <user> incus-admin lands them in neither group — box_tier() none, ready project unreachable. Grant's "no re-grant needed" holds only while they hold incus. This is documented in help revoke because it lives at the seam between two commands and only the help sits where an operator sees both before acting. Worth confirming you're happy with the wording rather than the behavior.

3. Where the coverage actually lives. test/cli.sh records the design decision (admin member IS usermoded); criterion (o) is what measures it. The shim incus ignores INCUS_SOCKET and permissions entirely, which is precisely why round 1's bug survived a green suite. If criterion (o) ever gets skipped in CI, this PR's central mechanism goes unverified again — that's the thing to protect.

Merge order

heavy-duty/rig#49 (rig PR #53) is approved and waiting on you. It handles both worlds: if box grant still refuses admin members it warns and continues, and it needs no change once this lands. So either order works — but this one landing first is what makes rig#53's incus-admin path actually converge rather than warn.
