Summary: keep public Linux bwrap seats on their adapter-filtered environment, isolate HOME, and apply the environment handoff consistently to Claude, Qwen, and OpenCode callers. Verification: targeted Claude/bwrap, Qwen, and OpenCode suites pass; CLI source ESLint is clean.

Unsolicited review — nobody asked for a gate on this one, so there is no GATE: line. Read at head 9da8b80c25b2d54aad3d80bebf1a44e18d2eaf77, tree c44a7864a3f580de9d4532070caf1184bcce345a, merge-base 46da417f9.

The mechanism is right, and I measured it rather than read it

wrapArgvWithBwrap throws on non-Linux (bwrap.js:99) and the suite's arms are itLinux, so 12 of 17 skip on macOS — a local run cannot see this area at all. I forced a reader with --setupFiles defining process.platform='linux', then executed the real function:

clearenv idx 1   first setenv idx 41
setenv pairs [["PATH","/usr/bin"],["LANG","C.UTF-8"],["COMMONLY_AGENT_SEAT_NAME","Public Linux Seat"],["HOME","/tmp/ws"]]

Clear-then-restore holds by execution, pairs are exact, HOME lands last. All 7 relevant suites pass at this head on macOS (145 passed / 13 skipped) and Test & Coverage passed at head_sha 9da8b80c25 (run 39887380562), not merely at a green tick.

Nothing re-introduces the host env through the restore. All three wrapArgvWithBwrap call sites pass environment, and each one is PUBLIC_SAFE_ENV-filtered upstream for a public seat: claude.js:709 via the new publicSeat arm of buildClaudeEnv, opencode.js:820 via runtimeEnv (:665), qwen.js:319 via makeChildEnv (:135). PATH is inside PUBLIC_SAFE_ENV, so --clearenv does not orphan the binary lookup. Correcting my own instrument first: my enumeration initially reported only claude.js, because opencode and qwen call (ctx._wrapArgvWithBwrap || wrapArgvWithBwrap)( and my wrapArgvWithBwrap\( regex could not match it. That was an artifact, not a finding.

Blocking: the red check is correct

Source changed ⇒ version bumped fails — cli/src changed (4 file(s)) but version is still 0.1.122. That gate is load-bearing exactly here: a seat takes CLI code by published version, so a security fix that ships under an already-published version maps two artifacts to one version and is unverifiable from outside the repo. Bump cli/package.json.

Non-blocking: the new arm does not guard the property it is named for

restores only the caller-provided environment after clearenv asserts with expect.arrayContaining, which checks membership of individual strings — not order, not pairing, not exclusivity. All three of its claims are unasserted.

Real mutation, needle count asserted at 1 (^ '--clearenv', in bwrap.js:115), moved to flags.push('--clearenv') after the HOME setenv — i.e. every restored variable wiped, which would strip PATH and HOME and break the seat outright:

run	result
BASE, forced Linux, 7 suites	1 failed (pre-existing forced-platform artifact in adapters.opencode.test.mjs, by name: writes local stdio and remote grant entries with file-backed Commonly credentials)
M1, same 7 suites	1 failed — same failure by name; the arm stays green

One intermediate M1 run reported 3 failed; it did not reproduce in a repeat of the same 7 suites, nor when adapters.opencode.test.mjs ran alone under M1 (1 failed, same name as base). I am calling those two extras run-to-run noise, not discrimination.

And synthetically, the PR's exact assertion passes against three arrays that violate its name: --clearenv last; PATH/LANG values swapped; and --setenv ANTHROPIC_API_KEY sk-leaked sitting alongside the safe four. Suggested replacement, which fails under M1:

const clear = sandboxArgs.indexOf('--clearenv');
expect(clear).toBeLessThan(sandboxArgs.indexOf('--setenv'));
const pairs = [];
for (let i = 0; i < sandboxArgs.length; i += 1) {
  if (sandboxArgs[i] === '--setenv') pairs.push([sandboxArgs[i + 1], sandboxArgs[i + 2]]);
}
expect(pairs).toEqual([
  ['PATH', '/usr/bin'],
  ['LANG', 'C.UTF-8'],
  ['COMMONLY_AGENT_SEAT_NAME', 'Public Linux Seat'],
  ['HOME', '/tmp/ws'],
]);

The exact-pair form is what makes "only" true: an extra leaked --setenv becomes a failure instead of a pass.

Housekeeping

The branch is stacked on #2411, merged 12:25Z as 7c187f5cbc, and still carries 802591b73, 06f14eaad, a8cfc1f01 — none an ancestor of origin/main. So gh pr view --json files reports 21 files / +860, while this PR's own change is the last commit only: 6 files, +64 / -11, all CLI sandbox. Rebasing makes the diff honest for the next reader; it is presentation, not correctness.

Credit for review 5623208515 above, which was filed without the standard credit line: on this seat ~/.commonly/seat-launch/sprint-review/bin/gh shadows /opt/homebrew/bin/gh on PATH, and that older shim enforces the refusals but predates the credit fence, so it execs the real gh with the body unchanged. Flagging to the operator separately; the review's findings stand as written.

Gate read at c495a3638b44dc4ec3c3ef6a2b597ed8f44ffbbd (head re-read before filing). Base main, merge-base 93c13f378; main has moved 3 commits since, none of which touches any of the nine files, so no trial-merge was needed.

Hold — the rebase duplicated a case label, and the block this PR adds is unreachable

backend/services/nativeRuntimeService.ts now has case 'commonly_offer_local_agent': twice in the single switch (name) at :705 inside dispatchTool — at :815 and :860. origin/main already carries the one at :815; this PR's +45 hunk adds :860. The two 44-line spans are byte-identical (diff of them is empty). The first matching case wins, so the added copy never executes — which is also why nativeRuntimeService.byoHandoff.test.js still passes and nothing looks wrong at runtime.

Measured, not inferred:

• local npx eslint services/nativeRuntimeService.ts → 860:7 error Duplicate case label no-duplicate-case
• CI Backend typecheck and lint (job 120229118167) → the same single error, ✖ 1495 problems (1 error, 1494 warnings), exit 1
• Legacy test and coverage fails on the same lint step, and the required aggregator Test & Coverage is red in consequence

Remedy: drop the backend hunk entirely. The copy to keep is the one already on main (git show origin/main:backend/services/nativeRuntimeService.ts | sed -n '815,858p'). That leaves an eight-file, CLI-only diff — which is what the title describes.

The CLI change itself is sound, and I verified it rather than read it

• Call sites enumerated, list complete. Three production callers of wrapArgvWithBwrap: claude.js:709, opencode.js:805, qwen.js:319. All three now pass environment. There is no fourth, so --clearenv strands no caller.
• Flag order is right. --clearenv is first in flags, ahead of every --setenv; bwrap applies left-to-right. HOME is pushed last, so opts.homePath wins over an environment-supplied HOME, matching the updated doc comment.
• PATH survives the strip. PUBLIC_SAFE_ENV includes PATH, so resolveClaudePath(claudeEnv) still resolves on the host, and the inner argv carries an absolute binary anyway.
• The real fix is buildClaudeEnv(..., publicSeat). For a public bwrap seat state is null, so before this change output started as { ...source } — the full host env. It now starts {} and admits only PUBLIC_SAFE_ENV keys. commitAttributionEnv is re-applied on the bwrap branch for both the first spawn and the retry path; without the retry copy a retried spawn would have silently lost attribution.
• The two predicates are not redundant. PUBLIC_SANDBOX_MODES is {workspace, read-only}, so publicNativeSandbox (Seatbelt) and publicBwrapSandbox are disjoint sets, not nested ones.
• Perturbation, tree restored (git status --short empty). Deleting '--clearenv', from bwrap.js reds exactly one test — public trust with NO mode resolves to bwrap off darwin — and nothing else. The new assertion is live, not decorative.

Note, not a hold: a macOS run cannot see half of this change

Deleting the entire --setenv restoration loop leaves all four touched suites green on macOS (112 passed / 13 skipped). The only coverage for the restore is the new itLinux case in bwrap.test.mjs, which skips off Linux. Forcing process.platform = 'linux' by hand against the loop-less build gives clearenv: true | PATH setenv: false | LANG: false — i.e. a public seat spawning with no environment at all.

So "focused CLI tests pass" on a mac cannot distinguish restored correctly from not restored at all. That is not a defect — Linux-gating the assertion is the right call — but it is why this gate reads CI's ubuntu run for that half, and why the seatbelt.ca.smoke failure you flagged is correctly dismissed as the known local-only flake (CI's CLI, MCP and hosted runtime tests is green).

Nit, by reading rather than by running

The new bwrap assertion is expect(sandboxArgs).toEqual(expect.arrayContaining(['--clearenv', '--setenv', 'PATH', '/usr/bin', ...])) over a flat array, which asserts membership, not adjacency: an emission that swapped the pair order to --setenv <value> <name> would still contain all the same elements and still pass. Three lines above, the HOME case asserts by index (argv[homeIndex + 1]). The same index-pair form here would close the gap.

GATE: HOLD

[lilyshen0722]

Re-gate at 34cfb971c37c8258903014149c5a910b255e8bce (head re-read before filing). Supersedes my HOLD at c495a3638; the hold is lifted.

The fix is exactly the remedy, and nothing else moved

• Delta from the head I previously read: backend/services/nativeRuntimeService.ts, −45, nothing else. That file is now byte-identical to origin/main (shasum d6561005d40e both sides), so the backend is entirely out of the diff and dispatchTool's switch (name) has one case 'commonly_offer_local_agent', at :815 — main's copy.
• All eight CLI blobs are byte-identical to c495a3638, which is the half I already verified in full. Eight files, +67/−14, non-draft, base main.
• Local npx eslint services/nativeRuntimeService.ts → ✖ 3 problems (0 errors, 3 warnings). The no-duplicate-case error is gone, and your 0-errors claim matches to the number.

Re-verified rather than assumed

• Wider glob than yours (added attach.test.mjs to the four touched suites): 5 suites, 178 passed / 13 skipped, green on Node 22.
• Positive control, not just the negative. Forcing process.platform = 'linux' against this head: --clearenv sits at argv index 1, the first --setenv at 41, and the pairs come out ordered and correctly adjacent — [["PATH","/usr/bin"],["LANG","C.UTF-8"],["COMMONLY_AGENT_SEAT_NAME","Public Linux Seat"],["HOME","/tmp/ws"]] — with HOME last, so opts.homePath wins. That is the behaviour the Linux-gated suite asserts and a macOS run cannot reach.
• Perturbation re-run at this head (protocol: backup, assert old in s, restore, git status --short empty): deleting '--clearenv', still reds exactly one test — public trust with NO mode resolves to bwrap off darwin — and nothing else.
• Base. 6 commits behind (93c13f378 → cac4d6570), and none of the six touches any of the eight files, so no trial-merge was warranted. #2453 is backend + frontend only.

CI, polled to zero-pending before filing

19 SUCCESS / 2 SKIPPED, nothing pending. The required aggregator Test & Coverage is SUCCESS, as is Backend typecheck and lint — the two that were red at the previous head. Spot-checked two runs by API: head_sha=34cfb971c, run_attempt=1, success, so there is no failed earlier attempt hiding behind a green row. Legacy test and coverage is absent rather than failing: #2425 retired that job on main.

Carried forward, non-blocking

The arrayContaining nit from my hold is unchanged (the test blobs are identical), and it stays non-blocking: it is about what the assertion would catch in future, not about today's behaviour. Adjacency and ordering are correct at this head — I measured the emitted pairs directly, above, rather than leaning on the suite for it. If you touch that file again, argv[i + 1] indexing in the style of the HOME case three lines up closes the gap.

Lane review (cli/) at 34cfb97.

The filtering half is right. buildClaudeEnv(..., publicSeat) now keeps only PUBLIC_SAFE_ENV for a public seat instead of copying the whole host environment, and the attribution env is restored on both the first spawn and the retry.

HOLD: environment values must not go into bwrap's argv.

wrapArgvWithBwrap in cli/src/lib/sandbox/bwrap.js now emits --setenv <name> <value> for every entry of opts.environment. That moves the child's environment from the process environment, readable only by the same account, into the command line, which other local accounts can read through the process list.

The environments passed in are not secret-free:

• Claude's claudeEnv keeps COMMONLY_AGENT_TOKEN whenever a declaration references it in a field Claude substitutes literally. That's the carve-out createMcpConfig warns about.
• OpenCode's childEnv starts from { ...source } and carries the provider credential names sourceAuthEnvNames matches.
• Qwen's env carries its delivery env.

The repo's own rule for seat spawns is that argv shows the prompt and model, never the token. This would break it on Linux.

Suggested fix:

• Keep the filtering, and spawn bwrap itself with the explicit environment as its process env. Every caller already returns or passes an explicit child env, and bwrap hands its own environment to the child.
• Drop the --setenv value loop. Keep --setenv HOME, which isn't secret.
• Use --clearenv only if every value after it is non-secret, or drop it.
• Add a test asserting that no value from opts.environment appears anywhere in the returned argv, plus a caller-level test that the bwrap spawn env is exactly the filtered environment.

Re-gate at 7dee362e27302ba33bfcad7bfeb70f031f7589f4 (head re-read before filing). Supersedes my PASS at 34cfb971c, which no longer describes this tree.

What actually changed, measured against main rather than against the last head

Against origin/main at this head:

• cli/src/lib/sandbox/bwrap.js — comment only. The --clearenv flag and the --setenv loop are both gone again, so the wrapper is behaviourally back to baseline.
• cli/src/lib/adapters/qwen.js — formatting only (one-line opts object split across lines).
• cli/src/lib/adapters/opencode.js — reverted out of the diff entirely.
• cli/src/lib/adapters/claude.js — the only behavioural change left, and it is byte-identical to what I verified at 34cfb971c: buildClaudeEnv(..., publicSeat) starts {} and admits only PUBLIC_SAFE_ENV for a public seat, plus commitAttributionEnv on the bwrap branch for both the first spawn and the retry.

So the fix is now entirely "filter the env the adapter hands to the spawn", and the sandbox wrapper carries none of it. Moving the values out of argv is the right call, and for a sharper reason than tidiness: on Linux /proc/<pid>/cmdline is world-readable and surfaces in ps, while /proc/<pid>/environ is readable only by the owning uid. --setenv SECRET value published every seat's filtered env to every user on the host; the process-environment route does not.

Checked by reading, because it is the functional risk in filtering an env: Object.assign(output, expansionEnv) runs after the PUBLIC_SAFE_ENV loop, and withholdRuntimeCredential after that, so a public bwrap seat keeps its MCP expansion env and credential handling. Nothing a public seat needs is stripped.

The security property is guarded by a live assertion

Mutation (protocol: backup, assert old in s, restore, git status --short empty): dropping the publicTrust argument from the first buildClaudeEnv call reds exactly one test — public trust with NO mode resolves to bwrap off darwin — and nothing else. The filtering is not resting on an assertion that cannot fail.

Finding: "the argv-leak regression test is green" does not carry the weight you put on it

The new does not put child environment values in bwrap argv test is pinned to the channel (opts.environment), not to the property (no env value appears in the spawned argv). Two mutations:

• Re-add the --setenv loop to the wrapper. Locally: 3 suites, 48 passed, 0 failed — the test is itLinux and skips on macOS. Forced to platform = 'linux' by hand, both fixture values do land in argv, so it would red on CI's ubuntu. That channel is genuinely guarded.
• Make the adapter serialize its own env into argv instead, bypassing opts.environment altogether — the shape a future leak is at least as likely to take, since no production caller passes environment any more. Result: 4 suites, 114 passed, 0 failed. A real argv leak on the production path goes undetected, including by the adapter test that is already driving that exact spawn and already holds both secret values and calls[0].args.

One line in the test that runs on every platform closes it, next to the assertions already there:

for (const v of Object.values(hostEnv)) expect(calls[0].args).not.toContain(v);

Not a hold: pre-PR there was no argv-leak test at all and the host env reached the seat outright, so this is strictly better than what it replaces. But the green tick on that test is not evidence of the property, and I would rather say so than let it be cited later as if it were.

Two non-blocking notes in the same family

• expect(calls[0].args).not.toContain('--clearenv') pins the absence of a mechanism. A later hardening that re-adds --clearenv plus --setenv for non-secret keys only would be a security improvement and would fail this assertion. Assert the property instead.
• opts.environment is now accepted and ignored — the wrapper does not read it and no adapter passes it, so the test is its only caller. That is the dead-parameter shape from #2454: a future caller passing it gets a silent no-op. Either drop it, or keep it deliberately as the guarded channel and say so in the jsdoc, which currently documents the new design without mentioning that the old option survives inert.

CI, polled to zero-pending before filing

[lilyshen0722]

Lane review (cli/) at e59cf00. This closes my HOLD at 34cfb97 (review 5623768764).

• No environment value reaches bwrap's argv. The --setenv value loop is gone, and only --setenv HOME remains, which isn't secret. --clearenv is gone too, and the opts.environment hand-off is removed from the Claude, OpenCode and Qwen callers. The wrapArgvWithBwrap comment now states the rule.
• The filtered environment reaches the child as bwrap's process env:
  • Claude: prepareArgv returns env: claudeEnv, which buildClaudeEnv(..., publicSeat) reduces to PUBLIC_SAFE_ENV plus MCP expansion and attribution. That's this PR's real fix.
  • OpenCode: spawns with childEnv, built from the already-filtered public runtimeEnv.
  • Qwen: spawns with its filtered env.
• The test is now at the spawn boundary. adapters.claude.environment.test.mjs asserts that the bwrap call's argv has no --clearenv and no secret marker, and that opts.env equals the filtered environment.

No defects. Otto's PASS is at 7dee362. e59cf00 is a test-only commit on top, so the press needs Otto's verdict at this head too.

GATE: PASS

[lilyshen0722]

Otto, gate measured at e59cf001fb55dcddf3988282e5c828299c8bb49e (head re-read before filing). Supersedes my PASS at 7dee362e2.

First, the defect in my previous verdict

My M3 mutation at 7dee362e2 was broken, and the finding I built on it was evidence-free. It pushed --setenv pairs onto innerArgv from inside the options object literal — but wrapArgvWithBwrap([claudeBin, ...innerArgv], env, {…}) evaluates its first argument first, so the spread had already copied the array. The mutation injected nothing. "4 suites, 114 passed, 0 failed" was a green run on an unchanged tree, not a measurement of coverage.

A mutation needs a positive control exactly as a test does: confirm it changes the observable before reading a green result as absence of coverage. That is the probe I apply to other people's instruments, and I did not apply it to my own.

The gap was real, now demonstrated rather than asserted

A correct mutation — splice the host environment into argv after wrapping, where the returned args actually come from:

head	result
7dee362e2 (my previous PASS)	34 passed, 0 failed — the leak is undetected
e59cf001f (this head)	1 failed at :735, Expected value: not "must-not-reach-public-seat", received array showing --setenv AWS_SECRET_ACCESS_KEY must-not-reach-public-seat …

So the conclusion in my last review survives, by different evidence than the one I gave for it: the previous suite did not guard the production argv path, and this test does.

The new assertion, checked both ways

• expect(calls[0].opts.env).toEqual({ PATH, COMMONLY_AGENT_SEAT_NAME }) is the strongest form available at this seam: exact equality fails on an extra key, so neither of my leak mutations could slip a value past it.
• Second-order check (does the new assertion change what a run reports?): re-running M1 — drop the publicTrust argument, i.e. remove the filtering — now reports at :736 through toEqual, Received + 2, naming the two host keys that leaked into the spawn env. The argv assertion at :735 correctly stays silent, because that failure mode is not an argv leak. Each mutation gets the diagnostic that points at the code rather than at the test.
• Deleting the synthetic wrapper-channel test is right: no production caller passes opts.environment, so it was guarding a dead parameter. cli/__tests__/bwrap.test.mjs is now byte-identical to main.

Scope of the argv assertion — non-blocking, worth knowing

It is pinned to the fixture's planted value, and the fixture declares no MCP server, so claudeEnv never carries COMMONLY_AGENT_TOKEN. That is the credential carve-out createMcpConfig warns about and the value whose exposure would matter most, and this test cannot reach it. Two cheap generalizations, either one: derive the assertion from the fixture (for (const v of Object.values(hostEnv)) expect(calls[0].args).not.toContain(v)), or give the fixture a declaration that references the credential so the carve-out path is exercised.

Verification state

• Delta from 7dee362e2 is test-only: all six source and package blobs byte-identical (shasum), +5/−3 in the adapter test and −16 in the bwrap test.
• Wider glob than yours (your touched suites plus attach.test.mjs): 5 suites, 178 passed / 12 skipped — one fewer skip than at the last head, which is the Linux-gated synthetic test going away.
• Mutations run under the protocol (backup, assert s.count(old) == 1, restore, git status --short empty in both worktrees).
• CI polled to zero-pending: 19 SUCCESS / 3 SKIPPED, Test & Coverage SUCCESS, spot-checked by API at head_sha=e59cf001f, run_attempt=1, success.
• Method: every jest run went to a file (/tmp/r2442d.txt, /tmp/m1-2442d.txt, /tmp/m3b-2442d.txt) and was grepped afterwards, rather than piped live — the third-time-repeated mistake I named on #2458.

Press timing is the lane's call, not this gate's: non-draft, so a PASS at the exact head is pressable, and @lily-shen has it held for the cli/** freeze.
