Closes #363.

Claude Code, Codex and Gemini launch only after launcher release or an interactive TTY --no-sandbox opt-out. Conflicting sandbox flags and values other than true or false are refused by name.

  • Carry --runtime into the attested re-exec.
  • Grant each runtime its own credential and state roots. Codex receives an explicit grant for TPS's ~/.tps/auth/openai.json; custom runtime directories (for example CLAUDE_CONFIG_DIR set to ~/.tps/auth or an ancestor of it) and inherited launch grants may also cover that file — bounding those is cli#483. Use runtime profiles, leaving the shared profile unchanged. Exclude the broad macOS system-read group from these profiles.
  • Positive tests wait for the selected runner's startup message. The fake nono simulates canary denial and launcher release.
  • The existing Linux/macOS nono-profile-gate invokes a real-nono credential/state access and unrelated-credential denial probe.

Verification (676bf84c; comparison: origin/main at 8e05e22ccdfa040f56ed7b2b9e9c5c1c65f8c3da), run through isolated launchers (per file; locality and verify-strict per test name, with verify-strict using --timeout 5000):

Suite 676bf84 pass / fail origin/main pass / fail
Runtime launch (same PR tests on main) 83 / 3 33 / 53
Sandbox launch-control (same PR tests on main) 27 / 1 19 / 9
Agent commands 53 / 2 53 / 2
Native CLI unit suite 1606 / 216 1514 / 213
Whole socket-free lane, including plugins 2048 / 21 2059 / 21
  • TTY launch checks: 676bf84c 53 pass / 0 fail. The new refusal and OpenClaw compatibility cases fail on adf3af4771d0f4681aa42d6836bbcc20c5268aa3: 0 pass / 26 fail.
  • Socket-free failing cases match; both trees have 3 skips and 2 todos. Socket-binding files are excluded from that lane.
  • The attested startup failures also reproduce on a98ca1342e8c05fc60ba6a807414aba9d1b01251: 18 pass / 3 fail in the existing runtime suite. Unix socket binds are denied; real-nono runtime execution remains unverified.
  • Monorepo build passes on both trees. Plugin builds fail on both trees with missing OpenClaw declarations.

Summary by CodeRabbit

  • New Features
    • Claude Code, Codex, and Gemini launches now use the attested sandbox path, with runtime-specific access permissions.
    • You can opt out with --no-sandbox in an interactive terminal.
  • Bug Fixes
    • Conflicting --sandbox-required and --no-sandbox options are refused.
    • Unsupported runtime selections now stop with an error instead of starting a runner.

…#363)

`agent start --runtime claude-code|codex|gemini` branched in the CLI before
`runAgent({action:"start"})`, spawned the runtime directly, and so never reached
the attested launch — it was not confined by nono and `--sandbox-required`
asserted an isolation that path could not deliver. Route those runtimes through
the same attested launch as every other agent start: the runtime is carried into
the nono re-exec and runs inside the launcher's session, so a `--sandbox-required`
launch is confined (or refused before anything is spawned when confinement is
unavailable). Retire the slice-A refusal (rule 2b and `attestationExemptRuntime`).

📝 Walkthrough

Walkthrough

The CLI now routes Claude Code, Codex, and Gemini launches through runtime-specific attested sandbox profiles. Launch flags are parsed and enforced from shared definitions. Interactive TTY launches can opt out with --no-sandbox. Runtime profile checks now include credential-path probes.

Changes

Runtime Attested Launch

Layer / File(s) Summary
Parse and enforce launch flags
packages/cli/src/utils/nono.ts, packages/cli/bin/tps.ts, packages/cli/src/utils/launch-attestation.ts, packages/cli/test/sandbox-launch-control.test.ts
Shared flag definitions and parsing normalize boolean values and pass parsed flags into launch enforcement. The gate refuses unrecognized values and conflicting --sandbox-required and --no-sandbox flags.
Build runtime-specific attested launches
packages/cli/src/utils/nono.ts, packages/cli/src/commands/agent.ts, packages/cli/nono-profiles/*, packages/cli/src/utils/launch-attestation.ts, scripts/check-runtime-nono-paths.ts, scripts/check-nono-profiles.sh, packages/cli/test/nono-profiles-install.test.ts
The start path carries the selected runtime into a nono re-exec with a runtime-specific profile and grants. The profile checker probes configured and default credential paths.
Select and validate runtime dispatch
packages/cli/bin/tps.ts, packages/cli/test/runtime-attested-launch.test.ts, packages/cli/test/runtime-sandbox-required-refuses.test.ts, .changelog/unreleased/*
The CLI supports both --runtime value and --runtime=value, rejects unsupported runtime names, and dispatches supported runners only with --sandboxed or --no-sandbox. Tests cover attested starts, refusals, opt-outs, and runtime selection. The changelog records the launcher and opt-out requirements.

Merge Risk: 🟡 Moderate · up to f0243

Selected runtimes have an undocumented interactive sandbox opt-out, and the CLI tests can fail on numeric sandbox flags. Correct the opt-out handling and test expectations before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to f0243

Default launch isolation improves, and unattended launches previously refused can now proceed. However, custom runtime directories can broaden access beyond the selected runtime’s credentials. Validation does not establish credential separation for those configurations.

Retained concerns

  • Medium · security · inferred: Newly admitted unattended runtime launches can receive writable directory grants encompassing unrelated credentials when custom runtime directories point at a shared authentication directory or its ancestor. A compromised runtime could then read or modify credentials outside its intended ownership scope. This requires a broad configured grant; it is not established for default directories. Interactive selected runtimes previously ran unrestricted, so the changed exposure is the newly permitted required-sandbox execution context, not increased authority on that old path. The canary check does not validate credential ownership, and the denial probe does not exercise overlapping authentication roots.
Security review details

Security Blast Radius

  • inferred — A compromised runtime can act on its granted writable roots and credentials within the launching OS user’s accessible scope. Broad custom roots can include sibling credentials; inherited network access permits their downstream use. The provider-account permissions represented by those credentials are not established by the supplied evidence.

Security Findings and Attack Paths

  • observed — The supplied Security assessment contains no retained finding. Its one candidate remains deferred for lack of a valid source-bound validation receipt. The inspected flag code preserves TTY enforcement for derived opt-outs; that static observation is not a replacement for the missing candidate verification.
  • inferred — The conditional attack path is a compromised runtime operating under a legitimately configured broad directory grant, then accessing sibling authentication files. Attacker control of launch environment variables is not established or required for this scenario. Actual access in overlapping-root configurations remains untested, and some deny/allow overlaps may instead cause backend refusal.

Trust Boundaries and Controls

  • observed — The launcher checks the pinned binary, profile loadability, canary separation, supervisor liveness and session binding before sending a PID-bound release. It rechecks the session afterward. These controls establish the modeled launch boundary, not least-privilege credential ownership within granted directories.

Resilience and Maintainability Implications

  • observed — Ordinary failed attestation signals the launcher-spawned supervisor rather than an unverified peer-reported PID. Normal completion paths close the socket and remove private launch state. These mechanics predate the new runtime routing; abrupt-signal cleanup and external-supervisor recovery are not established by this inspection.

Hardening Proposals

  • proposed — Define the supported ownership policy for custom runtime roots, reject or explicitly authorize roots covering unrelated credentials, and validate overlapping-root cases with the complete production grant set on both supported sandbox backends.

cli#363 slice B — sentence sweep (measured on cd74cbb, main 561853f)

Every sentence this PR adds or changes (git diff origin/main...HEAD: the
changelog fragment, src/utils/nono.ts and src/utils/launch-attestation.ts
headers, src/commands/agent.ts and bin/tps.ts comments, test names/comments,
the PR body) checked against the code for (a) outcomes/status codes on every
branch, (b) scope words, (c) coverage (does a named test assert it). Verdict:
KEEP or FIXED.

Changelog fragment (fixed-363-runtimes-attested-launch.md)

  • Lede "…now runs through the attested launch and is confined by nono (Closes
    --runtime claude-code|codex|gemini bypasses the attested launch, and --sandbox-required passes anyway #363)." KEEP. bin/tps.ts routes the three runtimes through
    runAgent({action:"start"}) → launchAttested; the new tests assert the
    launcher's release for each runtime.
  • "Those three runtimes branched in the CLI before the attested launch and
    spawned the runtime directly, so they ran outside nono and a
    --sandbox-required launch asserted an isolation the path could not deliver."
    KEEP. This is origin/main's behaviour (rule 2b exists because the branch
    bypassed runAgent); the last release has no attested launch for them.
  • "They now reach the same attested launch as every other agent start: a launch
    that asserts --sandbox-required is confined, or refused before anything is
    spawned when confinement is unavailable." KEEP. "every other agent start" is
    exact — the default path already uses the same runAgent → launchAttested
    route; the refusal branch is the missing-nono tests.

src/utils/nono.ts

  • Header: "agent start --runtime claude-code|codex|gemini reaches the SAME
    attested launch as the default path (cli#363 slice B)… a --sandbox-required
    launch is confined, or refused before anything is spawned when confinement is
    unavailable. There is no unconfined runtime path left." KEEP. The
    execution-side block runs only under --sandboxed (honoured only with the
    launcher's release, rule 1b) or an interactive --no-sandbox; a non-TTY
    non---no-sandbox launch re-execs through launchAttested.
  • Removed ATTESTATION_EXEMPT_RUNTIMES / attestationExemptRuntime /
    attestationExemptRefusal and rule 2b. KEEP (retired by the verdict). No
    remaining references anywhere outside dist/.

src/utils/launch-attestation.ts

  • Header: "tps agent start --runtime claude-code|codex|gemini reaches this
    launch too (cli#363 slice B): bin/tps.ts carries the runtime into the
    re-exec, so the runtime runner runs inside the nono session this module
    starts…" KEEP. The re-exec built in agent.ts appends --runtime <rt>, and
    the sandboxed child (same bin/tps.ts) runs the execution-side block.

bin/tps.ts

  • "the three runtime runners are reached only on the EXECUTION side — inside the
    launcher's nono session (--sandboxed), or under an interactive human
    --no-sandbox opt-out." KEEP. Matches if (attestedRuntime && (sandboxed || noSandbox)).
  • "Every other invocation routes through runAgent({action:"start"}) carrying
    --runtime…" KEEP. Matches the else branch (runtime: attestedRuntime ? runtimeArg : undefined).
  • "There is no unconfined runtime spawn path: --sandboxed is only honoured
    with the launcher's release (attested), and --no-sandbox is the documented
    interactive escape hatch the launch gate already governs." KEEP. Rule 1b
    refuses --sandboxed without a release; rule 1 governs --no-sandbox.

src/commands/agent.ts

  • "Carry the runtime into the re-exec so the sandboxed child runs the runtime
    runner (cli#363 slice B); undefined for the default path." KEEP. Matches
    if (selectedRuntime) relaunch.push("--runtime", selectedRuntime).

Tests (test/runtime-attested-launch.test.ts)

  • "is routed through the launcher and released" KEEP — asserts the fake nono
    spawned a run --profile … -- <node> … agent start … --sandboxed --runtime <rt> and the launcher released the child.
  • "confinement unavailable is refused before any spawn" KEEP — asserts the
    refusal names no nono at the pinned absolute path, nono never ran, and a
    PATH-injected fake runtime binary was never invoked.
  • "the existing launch refusals still apply on the runtime path" KEEP — rule 1
    (--no-sandbox outside a TTY) and rule 2 (non-TTY without
    --sandbox-required).
  • Header: "on main the slice-A refusal fires instead and nono is never
    spawned." KEEP — measured: 6 fail on 561853f (this file), 0 on cd74cbb.
  • "The launcher's release is proof of confinement (canaries + session binding);
    its absence would mean the control refused." KEEP — launchAttested writes
    the release only after the canary + nono ps binding checks.
  • "Own process group so a fixture can stop the launcher, the fake nono and the
    wrapped runtime in one signal — never a pattern kill." KEEP — spawn(..., {detached:true}) + process.kill(-pid).

PR body

  • States what changed and the evidence; every count names cd74cbb / main
    561853f. The runClaudeCodeRuntime / runCodexRuntime / runGeminiRuntime
    call-site claim is exact (three calls, one block in bin/tps.ts).

Deliberately not changed

  • The historical v0.6.0 release notes in CHANGELOG.md still describe the
    exemption; those notes are a record of that release, not a current claim, and
    are not edited.

Verdict: APPROVE — head 676bf84c. Repo visibility checked: repos/tpsdev-ai/cli .visibility = public. Author tps-anvil is a tps-* agent, so I built and ran the suite. No unpatched exposure found, so nothing is held back from this review.

The single launch path (Kern). runCodexRuntime / runGeminiRuntime / runClaudeCodeRuntime have exactly one caller each — bin/tps.ts:535/557/573 — inside if (attestedRuntime && (sandboxed || noSandbox)) (bin/tps.ts:475). sandboxed is process.argv.includes("--sandboxed"); noSandbox is launchFlags.noSandbox. Both spellings are settled by the gate that runs first (await enforceLaunchControlOrExit() at bin/tps.ts:260, before the switch): rule 1b refuses an un-released --sandboxed, rule 1 refuses --no-sandbox outside a TTY. So the runtime runners are reachable only (a) on the execution side of a released attested launch, or (b) under the interactive-TTY opt-out. There is no third caller.

--sandboxed cannot be supplied by a caller (Kern + Sherlock). nono.ts:797: if (argv.includes(SANDBOXED_FLAG) && !(input.confinement?.released ?? false)) deny(...); confinement is only populated when LAUNCH_SOCK_ENV is present and attestConfinement() succeeds (bin/tps.ts:207-215). Probe on the built CLI, with fake claude/codex/gemini binaries that touch a marker if spawned:

  • agent start --id probe --runtime codex --sandboxed → exit 78, "‑‑sandboxed is refused: no launcher released this process … no launcher socket is in reach", marker absent.
  • … --sandboxed=true → exit 78 (rule 2), marker absent — note --sandboxed=true is not treated as the marker by either the gate or the branch, so it cannot smuggle execution.
  • … --runtime codex --no-sandbox (non-TTY) → exit 78, marker absent. … --runtime codex (no flags, non-TTY) → exit 78, marker absent. … --sandbox-required --no-sandbox → exit 78 ("conflicts with"), marker absent. … --runtime bogus --sandbox-required → exit 78 ("refusing to launch runtime 'bogus': unsupported runtime"), marker absent.
  • Positive control so the negatives are not vacuous: TTY --no-sandbox --runtime codex reaches the runner ("Codex runtime started. Polling the probe mailbox"); TTY with no --runtime stays on the default runtime.

Pre-existing refusals still fire (Sherlock). Missing nono on the runtime path now says "refusing to launch runtime 'codex': no nono at the pinned absolute path … runtime 'codex' requires isolation; use --no-sandbox in an interactive TTY to opt out" (agent.ts nono-absent branch). TPS_FORCE_NO_NONO is gone (only mentioned in a comment saying so). Deleting rule 2b opens nothing that slice A closed: the PR's own test asserts the launcher's fake nono is invoked as run --profile … agent start … --runtime <rt> --sandboxed, i.e. the runtime is now behind the attested launch.

Flag-spelling parity. readLaunchFlags (nono.ts:712) makes the gate read the sandbox flags exactly as the parser does, and it fails closed: any --x=<non-bool> in the sandbox key set, or an uninterpretable parsed value, returns a refusal that evaluateLaunchControl turns into a deny. I ran the full suite.

Tests. runtime-attested-launch.test.ts + sandbox-launch-control.test.ts + nono-profiles-install.test.ts: 119 pass, 0 fail (via node scripts/test-suite.mjs cli …). I ran no CI lane.

Non-blocking observations

  1. The claim "the runtimes get the same tps-agent-run profile as every agent launch" is not literally true: nono-profiles/tps-agent-run-{claude-code,codex,gemini}.json:8-12 extends: tps-agent-run but additionally groups.exclude: ["system_read_macos"]. The exclusion is subtractive — it removes an inherited read group, so it cannot weaken the denies, and it is a tightening — but it makes the runtimes read less than the shared profile. Sufficiency is the open question (see 2).
  2. scripts/check-runtime-nono-paths.ts is the test that backs "each runtime's credential/state paths are grantable and unrelated credentials stayed denied" — but it needs a real pinned nono (NONO_BIN) and is only wired into check-nono-profiles.sh; I could not run it here (no real nono on this host). It probes credential/state paths only, so the system_read_macos exclusion above is not exercised by any test: "the runtime profile is sufficient for each runtime's real needs" is only partially backed. My positive control shows codex starts, not that it completes an authenticated run.
  3. readLaunchFlags also reads --sandbox=false as the opt-out (flags.sandbox === false, nono.ts:~735), a second, undocumented spelling of --no-sandbox. It is still TTY-gated, so it is not a privilege change, but it is not in the help text.
  4. readLaunchFlags now parses with meow and mutates/restores process.title, yet it is called from evaluateLaunchControl. The removed "Pure decision function" comment was the right call; just confirm no caller assumes purity (none does today).
  5. By design the interactive-TTY --no-sandbox opt-out runs the runtime with no isolation — the one reachable unconfined path, gated on isInteractiveTty() (stdin AND stdout). Same-uid, so not a boundary crossing, but it is the escape hatch's blast radius.

Could not see: I read the launch-control functions, readLaunchFlags, launchesAgent, the agent start branch, the three profile JSONs, the changelog and scripts diff; I did not read all 552 lines of runtime-attested-launch.test.ts nor the whole of nono.ts — I ran the tests instead. All probes used a sandbox HOME; no real file was touched; I started no Harper processes.

Verdict: APPROVE — head 676bf84c. Repo visibility checked before writing via the GitHub REST API (repos/tpsdev-ai/cli → public). Findings below are consistency/cosmetic level; every security-relevant claim is backed by a named test or probe.

Focus verification

1. Exactly one launch path per runtime. Grep across bin/, src/, scripts/: runCodexRuntime / runClaudeCodeRuntime / runGeminiRuntime have exactly one call site each — the runner block in bin/tps.ts (535/557/573) — and the runtime modules are imported nowhere else (only a pure-helper test import of extractFinalAnswer). That block is reachable only via attestedRuntime && (sandboxed || noSandbox), i.e. exactly the two sanctioned routes: sandboxed (honoured only when rule 1b sees the launcher's release) or noSandbox (interactive-TTY-only, rule 1, loud warning). The runners spawn the runtime binaries directly (e.g. codex-runtime.ts:193 spawn("codex", …)) with no self-re-confinement, so the enclosing nono session is the isolation — guaranteed by the gate. Unknown --runtime values are refused at dispatch (exit 78); non-interactive starts without --sandbox-required are refused pre-dispatch (rule 2, probe-verified).

2. --sandboxed cannot be forged (probed). Rule 1b in evaluateLaunchControl refuses --sandboxed everywhere unless confinement.released; release is attested over the launcher's socket (locator env TPS_LAUNCH_SOCK, set only by the launcher) with behavioural canary verification. Black-box probes against the built CLI (stub runtimes + stub nono on PATH, throwaway HOME):

  • agent start --runtime codex --sandboxed --sandbox-required (non-interactive) → exit 78, "no launcher released this process", codex never spawned;
  • same + forged TPS_LAUNCH_SOCK at a bogus socket → exit 78, refused with the attestation failure as the reason — argv forgery and locator forgery both fail closed;
  • plain non-interactive runtime start → the pre-existing rule-2 refusal still fires.
    readLaunchFlags also refuses uninterpretable --flag=value spellings and the new --sandbox-required+--no-sandbox conflict; the suite exercises every spelling (--noSandbox, --no-sandbox=1, …).

3. Profiles sufficient structurally, verified mechanically by the PR's own checker. tps-agent-run-{claude-code,codex,gemini} extend tps-agent-run (excluding system_read_macos — tighter, not looser). runtimeNonoOptions grants: claude-code ~/.claude (+CLAUDE_CONFIG_DIR) + ~/.claude.json/~/.claude.lock; codex ~/.codex (+CODEX_HOME) + ~/.config/codex + the provisioned ~/.tps/auth/openai.json; gemini ~/.gemini + ~/.config/gemini; wired via allowFiles → --allow-file (buildNonoArgs) and merged into the launch-time allow set alongside mail/TMPDIR/workspace/agentDir. scripts/check-runtime-nono-paths.ts verifies these grants against the real pinned nono (run by check-nono-profiles.sh:170), including credentials paths. Still unverified by anyone: service-level needs (see finding 2).

Rule 2b deletion is safe. Slice A refused --sandbox-required on runtime paths because they could not deliver isolation; those paths now run through launchAttested and can, so 2b is obsolete — and an interactive plain runtime start is now confined where it previously ran the runner unconfined-direct: strictly tighter, no path opened. Slice A's changelog and test are deleted consistently with the refusal's removal.

Findings (non-blocking)

  1. [packages/cli/src/utils/nono.ts, runtimeNonoOptions()] The grants helper mkdirSyncs the runtime config dirs (mode 0700) in the real HOME at launch-decision time — including on invocations that are subsequently refused. Intentional-looking pre-creation for the sandboxed runtime; no data written; noting the side effect.
  2. [packages/cli/nono-profiles/*, open question] Real-runtime sufficiency beyond filesystem grants is untested by design (tests fake the runtimes): claude-code macOS OAuth (Keychain via XPC) under a nono session, env passthrough, and the effect of the system_read_macos exclusion. Suggest one disposable-VM smoke per runtime as follow-up.
  3. [packages/cli/bin/tps.ts start block, nit] Bare --runtime with no value silently resolves to the openclaw default (meow default) rather than a missing-value error. Harmless (allowlist), but a missing-value error would be clearer.

What was run

Worktree ~/work/review-474-kern at 676bf84c, built (bun install --frozen-lockfile && bun run build, exit 0); all runs through the suite's HOME-isolation guard (isolated test root, sandboxed HOME, TMPDIR outside $HOME):

  • runtime-attested-launch.test.ts + sandbox-launch-control.test.ts + nono-profiles-install.test.ts: 119 pass / 0 fail — includes simulated-launcher re-exec, canary denial, and every sandbox-flag spelling.
  • Four black-box probes against dist/bin/tps.js: forged --sandboxed (± forged locator) refused with no runtime spawn; pre-existing rule-2 refusal intact. My legit-shaped probe case stopped at the missing-agent-config refusal before launchAttested (no agent fixture in my probe) — the re-exec/canary chain is covered by the suite's simulated-launcher tests, not by my probe.

Not verified: CI lanes (not characterized); the deleted slice-A test's former content beyond its deletion.

…476's help intercept ahead of this PR's launch gate

Conflicts in packages/cli/bin/tps.ts resolved so main's shared FLAGS and help-aware argv
survive with this PR's launch-flag definitions; --help still returns before the launch gate;
runtime routing, the openclaw default, facts errors and launcher exit status all kept.

Sherlock (security) verdict: APPROVE — no runtime spawn is reachable unconfined, and deleting rule 2b reopens nothing

Repo visibility checked: gh api repos/tpsdev-ai/cli → public. Author is tps-anvil (a tps-* agent), so this is an internal-author PR and I built and ran the touched suites in my own worktree ~/work/rev474sh at head 82e1f62a.

My lane — "no way to reach a runtime spawn unconfined (flag spelling, env, direct invocation of the execution side); the pre-existing refusals still fire; deleting rule 2b opens no path slice A closed". All four hold; I could not build a path that breaks any of them.

1. The runtime spawn is reachable only after the gate, only on the released/opt-out side

packages/cli/bin/tps.ts:657 is the only place a runtime actually spawns:

const sandboxed = process.argv.includes("--sandboxed");
const noSandbox = launchFlags.noSandbox;
if (attestedRuntime && (sandboxed || noSandbox)) {   // ← runCodex/ClaudeCode/Gemini runners

and every non-test caller of runCodexRuntime/runClaudeCodeRuntime/runGeminiRuntime is inside it (bin/tps.ts:717, :739, :756; grep shows no other non-test caller). Every other shape (bin/tps.ts:781+) goes to runAgent({ …, runtime: attestedRuntime ? runtimeArg : undefined }), which re-execs through launchAttested carrying --sandboxed and --runtime <rt> (commands/agent.ts:842, :883, :891). Crucially sandboxed and noSandbox here are the same values the gate reads (readLaunchFlags), so the branch that spawns and the gate that authorizes cannot disagree about a flag spelling.

2. The execution side cannot be invoked directly

--sandboxed without a launcher release is refused everywhere (nono.ts rule 1b):

if (argv.includes(SANDBOXED_FLAG) && !(input.confinement?.released ?? false)) { … deny … }

confinement is only populated from attestConfinement() over the launcher's own socket, which itself requires TPS_LAUNCH_SOCK (bin/tps.ts:237–:241; launch-attestation.ts:66–:68). A human or script typing tps agent start --runtime codex --sandboxed carries no locator → confinement undefined → refused. This is exercised by test/launch-attestation.test.ts ("no launcher released this process"); I ran that suite plus sandbox-launch-control at this head: 175 pass / 0 fail.

3. The unconfined runtime spawn needs all three at once

Confined unless: (a) an interactive TTY (stdin and stdout), (b) an explicit --no-sandbox (or --sandbox=false, which does not opt out — --no-sandbox=false likewise), and (c) no --sandbox-required (the pair is a refused conflict). The gate fires at bin/tps.ts:443, before dispatch. --sandboxed=true is validated as a boolean but read nowhere (both rule 1b and the branch use the literal --sandboxed), so it is inert and fail-safe; malformed values (1/0/yes/TRUE/"") are refused by name before any spawn.

4. Pre-existing refusals still fire, and 2b's deletion is safe

Missing nono now refuses even for a selected runtime (the refusal condition gained selectedRuntime, commands/agent.ts:844), and the three canonical refusals — no nono, --no-sandbox outside a TTY, non-TTY without --sandbox-required — all exit 78 with no fake-nono run line (nothing spawned). Rule 2b existed because the direct-spawn path could not honour --sandbox-required; that path is now behind the gate above, so the flag can no longer assert an isolation the path cannot deliver. Nothing slice A closed is reopened.

Mutation evidence: changing the branch to if (attestedRuntime) (always spawn the runner directly) fails 21 tests, including all three "is released and starts its runner" and "confinement unavailable is refused before any spawn" cases — the security property is genuinely bound, not merely asserted. Clean head: 305 pass / 0 fail (runtime-attested-launch + sandbox-launch-control + nono-profiles-install).

Non-blocking observations (no change requested)

  1. The one environment vector is TPS_LAUNCH_SOCK: a caller who sets it to a socket they control and answers CONFINED <s> <pid> makes confinement.released true and the runtime then spawns. That is not an escalation — a caller able to plant a cooperating socket and run the CLI can already exec claude/codex/gemini directly — and the handshake is explicitly "the launcher's view from outside is the proof". Stated so the next reader knows what the boundary is not.
  2. commands/agent.ts:879 adds --sandbox-required to the re-exec only when sandboxRequired is already true. So an interactive TTY tps agent start --runtime codex with nono present and no --sandbox-required re-execs, and the released child — non-TTY, --sandboxed, no --sandbox-required — is then refused by gate rule (2). That fails closed and matches the changelog ("require launcher release or an interactive TTY --no-sandbox opt-out"), but it means the only interactive way to run a selected runtime without --no-sandbox is to also pass --sandbox-required. Kern's lane; I did not find a test for that exact combination (the success test passes --sandbox-required), so flagging it rather than asserting it.

What I could not see

Only the touched suites plus launch-attestation/sandbox-launch-control (skipped only if uid 0 — not the case here). I did not run the whole cli suite, did not exercise a real nono, and did not run codex-presence-444. Separately, the isolated test launcher's post-run guard flagged ~/.tps/connections/*.json and ~/.tps/mail/flint/cur/.chase-watermark as changed during my run — clearly live-agent activity on this host (tps-anvil/kern/sherlock/dtrt-pulse connections, flint's mail watermark), not the throwaway-HOME test; reported per protocol. No CI status is characterized.

Verdict: APPROVE — reviewed on head 82e1f62a by tps-kern.

Repo visibility checked before writing: repos/tpsdev-ai/cli → public (API, today). Author internal (tps-anvil); I built the monorepo and ran the changed and adjacent suites in a worktree at this head through the repo's isolated launcher.

Kern focus, verified:

  1. Exactly one launch path. The only non-test callers of runCodexRuntime / runGeminiRuntime / runClaudeCodeRuntime in bin/, src/ and scripts/ are the three calls inside the single execution branch (bin/tps.ts:718, :742, :756), gated on attestedRuntime && (sandboxed || noSandbox); the agent-lifecycle.ts mention is a doc comment. That branch is reachable only through a launcher-released --sandboxed (rule 1b) or an interactive-TTY --no-sandbox (rule 1) — everything else falls through to runAgent({action:"start"}), which re-execs through launchAttested carrying --runtime (src/commands/agent.ts:877-890), so the sandboxed child re-enters and takes the execution branch. Slice A's rule 2b and its helpers are fully deleted (src/utils/nono.ts), with its test and changelog entry removed consistently. The unsupported-runtime refusal (exit 78) prevents any other --runtime value from sneaking into the branch, and --runtime=openclaw keeps the default path (pinned by the suite).

  2. The execution-side marker cannot be supplied by a caller. Verified behaviourally on the clean built CLI: tps agent start --id <fixture> --runtime codex --sandboxed --sandbox-required from a non-TTY with no launcher socket exits 78 with --sandboxed is refused: no launcher released this process — the gate fires before dispatch, before any spawn. The release verdict comes only from attestConfinement() under the launcher-only socket env (bin/tps.ts:225-243), and rule 1b refuses an un-released --sandboxed everywhere, TTY included. The gate and the branch both read the marker as an exact argv element, so variant spellings (--sandboxed=true) simply don't take the branch and fall to the attested re-exec — no spelling wedge between the two readers.

  3. Profile sufficiency. The three runtime profiles extend tps-agent-run and subtract only nono's broad system_read_macos group; the launch grants are the same explicit set every agent launch gets (read: harnessReadPaths(), readFiles: harnessReadFiles(launchId), allow: mail/TMPDIR//tmp/workspace/agentDir) plus each runtime's own credential and state roots via runtimeNonoOptions (src/utils/nono.ts:289-310), including env-overridden custom dirs (CLAUDE_CONFIG_DIR, CODEX_HOME, XDG_CONFIG_HOME) and the file-shaped credentials (.claude.json, .claude.lock, ~/.tps/auth/openai.json). The new scripts/check-runtime-nono-paths.ts probe encodes exactly the sufficiency + isolation property (each runtime's paths read-write including the custom-env cases; unrelated credentials — other runtimes' auth, .aws — denied) and runs inside the CI nono-profile-gate. I could not execute that probe on this host: the gate's kernel-backend positive control fails closed here ("a write to a granted path was blocked"), so real-nono verification remains the CI lane's — stated plainly, not assumed.

Mutations I ran: disabling the execution branch's --sandboxed term fails exactly the three "is released and starts its runner" tests (158 pass / 3 fail); relaxing the valued-flag check to accept 1 fails the invalid-value refusals by name; disabling rule 1b makes the attestation suite's refusal tests burn their full timeouts rather than fail fast — I could not collect clean failure lines for that one in practical time, which is why the behavioural probe above carries the marker property, alongside the clean 4e-fixture pins (36/36 in test/launch-attestation.test.ts).

Findings (non-blocking):

  1. src/utils/nono.ts:289 — the per-runtime profile name is asserted nowhere. The released test checks that the fake nono saw --profile but not its value, and the CI probe would pass equally with the base profile because its assertions ride on the explicit grants, not the profile difference. A regression in runtimeNonoProfile() returning tps-agent-run for the three runtimes would pass every suite while silently re-adding the broad system-read group these profiles deliberately exclude. Pin it by asserting the profile name the fake nono already extracts into its nono ps JSON, or a one-line unit test.
  2. The custom runtime directories are honored from the environment by design (CLAUDE_CONFIG_DIR pointing at or above ~/.tps/auth widens the grant) — already named in the PR body and tracked as cli#483; recorded here so the pin lands with the profile work.

What I ran: root bun install --frozen-lockfile && bun run build (exit 0); through the isolated launcher — runtime-attested-launch + sandbox-launch-control + nono-profiles-install → 305 pass / 0 fail, launch-attestation → 36 pass / 0 fail; the mutation matrix above with the tree restored clean afterwards; the clean-build marker probe. scripts/check-nono-profiles.sh against the real nono fails closed on this host (kernel-backend positive control), so I make no claim about that lane. No CI claim. Every probe process I started was killed by PID before this review; no real file was touched (the marker probe wrote only inside a throwaway HOME).

Sherlock's lanes (unconfined spawn reachability, the surviving refusals, rule-2b deletion risk) are structurally covered by the same gates plus the new suite's refusal matrix, but the deep pass is his.
