From 56b38528c5a3ffd7bfa56d0ab172433b481e2170 Mon Sep 17 00:00:00 2001 From: flint Date: Thu, 15 Oct 2026 22:47:50 +0000 Subject: [PATCH 01/46] fix(cli): keep --config through the attested re-exec, run worktree setup outside the sandbox, scan only tps's own flags (cli#516) - The attested re-exec carried --id but dropped --config, so `tps agent start --config ` ran the default config under nono. Carry it, and grant read of the directory it was read from. - Worktree setup/cleanup ran inside the sandbox, where the base repository's metadata is not granted, so it quietly did nothing. The parent now runs the hooks before entering and after leaving the sandbox; the sandboxed child skips them. A failure is a named WorktreeLifecycleError. - The sandbox-flag scan read every argv token, so `--sandbox ` inside a message or a wrapped command was refused as an invalid flag. Scan the parsed argument list, which inserts -- before a wrapped payload. --- .../unreleased/fixed-516-sandboxed-launch.md | 6 + packages/cli/bin/tps.ts | 37 +- packages/cli/src/commands/agent.ts | 48 +- packages/cli/src/utils/agent-lifecycle.ts | 24 +- .../cli/test/sandboxed-launch-516.test.ts | 437 ++++++++++++++++++ 5 files changed, 533 insertions(+), 19 deletions(-) create mode 100644 .changelog/unreleased/fixed-516-sandboxed-launch.md create mode 100644 packages/cli/test/sandboxed-launch-516.test.ts diff --git a/.changelog/unreleased/fixed-516-sandboxed-launch.md b/.changelog/unreleased/fixed-516-sandboxed-launch.md new file mode 100644 index 00000000..a7d60fe0 --- /dev/null +++ b/.changelog/unreleased/fixed-516-sandboxed-launch.md @@ -0,0 +1,6 @@ +- **Sandboxed agent launch keeps `--config`, manages the worktree outside the + sandbox, and scans only tps's own flags.** `tps agent start --config ` + now uses that file when nono is installed, worktree setup and cleanup run + where they can reach the base repository instead of silently doing nothing, + and a `--sandbox ` inside a message or a wrapped command is no longer + refused as a flag. diff --git a/packages/cli/bin/tps.ts b/packages/cli/bin/tps.ts index 52511a40..3e573e3b 100755 --- a/packages/cli/bin/tps.ts +++ b/packages/cli/bin/tps.ts @@ -17,8 +17,20 @@ try { process.exit(1); } -const launchFlags = readLaunchFlags(process.argv); -if (launchFlags.refusal) enforceLaunchControl({ argv: process.argv }); +/** + * tps's OWN arguments — the parsed list, with `--` inserted before a wrapped + * payload (`--message`, mail-watch `--exec`, secrets-guard's command).

Before, on macOS they failed for a fixture reason, not a product one: nono applies its built-in groups to every profile, and system_read_macos grants read on /private/var, /tmp and /Volumes, so a fixture HOME under /var/tmp sat inside a nono grant. nono then refused to start (the grant overlaps its state root HOME/.nono), and the launcher refused the profile because nono reported read access to the fixture HOME's credential files: correct refusals for a HOME that is genuinely readable. - realNonoHomeBase() picks a fixture base outside every launcher grant AND outside every path nono's built-in policy grants, checked with `nono why --profile default`, never assumed. On macOS that is /Users/Shared; on Linux /var/tmp, as before. When no candidate qualifies it throws, naming each candidate and the grant that rules it out. - The fixture profile grants the repo checkout and the interpreter directory exactly, not every ancestor: a read grant is recursive, and with bun under ~/.bun the ancestors were /Users and the operator's whole home. - The launcher cases stop waiting when the launcher exits and fail with its output, so a refusal is named instead of surfacing as a 45 s timeout.

The base chooser no longer depends on the output of `nono why --profile default`, which the pinned Linux nono answered with exit 0 and no output, failing all three cases in the attested lane. For each candidate base, probeNonoBuiltinRead() makes a scratch dir there with a fixture-like HOME and a file holding a random nonce, and runs real nono under a profile that only extends nono's `default` (the same `run` shape the real-nono cases already use) on `sh -c 'cat || echo '`: - the marker, exit 0: the read was denied, so the base is accepted; - the nonce, exit 0: the default policy grants read there, so it is rejected; - non-zero with no output: nono refused to start, so it is rejected and nono's stderr is quoted (on macOS, a default group overlapping the state root HOME/.nono); - anything else throws: an unknown answer is never "not granted". Neither the nonce nor the whole marker is in nono's argv. The launcher-grant check and the error naming every rejected candidate are unchanged. The unit tests drive a fake nono that runs the probe's own payload, one case each for granted, denied, refuses-to-start and unknown output, and each fails when its branch is removed.
