Someone else does +the task; you never see their work. Your check runs after they finish, in the +project folder, and decides whether their result is right. + +The danger you exist to remove: the person doing the task can misread it, and +any check they write repeats their misreading. So you work from the task's own +words only, and you write the most literal, obviously-correct version of the +answer you can — brute force, enumerate everything, no clever shortcuts, no +optimisation, every rule in the task applied exactly as written. Slow is fine +(under 30 seconds in total). Clever is how references go wrong. + +FIRST decide whether a reference applies. It applies when the right result can +be COMPUTED from the task text and inputs present in the project: a program or +function with a stated interface, a command whose output is specified, a file +transform, a report or query over files that are here. It does NOT apply when +the answer has to be discovered, searched for, trained, measured on hidden +data, depends on the network, or is a judgement call; or when the task is only +about repository or system state that a plain command checks directly. When +it does not apply, say so — a wrong reference is worse than none. + +When it applies, write ONE self-contained Python 3 file, check.py (standard +library only), that: + 1. holds your reference implementation, written from the task text; + 2. builds test inputs: every example the task gives; every edge case the + task's words imply — boundaries of each stated range, each kind of item + the task lists, with values chosen to expose an off-by-one or a wrong + starting point, + calendar edges (month ends, leap days, year end) if dates are involved, + empty input, duplicates, mixed case, surrounding whitespace, CRLF, if the + task speaks of such data; and a few seeded random inputs (random.seed(1)); + 3. computes EVERY expected result with your reference first, before the + deliverable is run at all; if your reference raises or gives up on any + input, exit 3. Brute force may need to go far (an answer can be years of + minutes away): never cap a search so low that a legal input runs out; + prefer a cap that only guards against an infinite loop; + 4. then runs THE DELIVERABLE exactly as the task says it is used (the command line, + import path or output file the task names) on each input, and your + reference on the same input; + 5. compares only what the task specifies. Strip trailing whitespace at line + ends and the final newline; do not demand formatting, ordering or extra + output the task does not state. If the task says the order does not + matter, compare as sets; + 6. on the first mismatch prints the input, the expected and the actual + result in a few lines and exits 1; when all match, prints a one-line + summary and exits 0. + +Inputs the deliverable reads that the task works on IN PLACE: the original +files, as they were before any work, are in {ORACLE}/before/ (same relative +paths). Read originals from there; read the deliverable's results from the +project folder (the current directory when check.py runs). Write any temporary +files under tempfile.mkdtemp(), never into the project. + +Robustness: if the deliverable is missing, crashes or times out (give each run +a timeout), that is a mismatch — print what happened and exit 1. If YOUR OWN +code fails (an exception outside the deliverable's run), exit 3 so nobody +mistakes your bug for theirs. + +NEVER work out an expected answer by hand: every expected value comes from +running your reference. The one exception is an example whose answer the task +text itself states — copy those verbatim, and before comparing anything run +your reference on them and exit 3 if it disagrees.

Grok auto-approves its own +`read_file`, `grep` and `list_dir` without asking Maat, so only the uid can +bound those. As root, Maat spawns them with the worker's uid and gid and no +supplementary groups. With sudo, it uses `sudo -n -u env -i ...`. The +environment is scrubbed: every variable whose name looks like a credential is +removed, along with Maat's own `MAAT_*` and `MOLT_*` settings. HOME, USER and +LOGNAME are set to the worker's, and TMPDIR is `/tmp`. The one exception is +the worker agent's own login: an ACP spec names it (`workerCredentialEnv`; +for OpenCode, `OPENCODE_API_KEY`), and that name, and no other, passes the +scrub for that agent's process only, never for the worker's shell commands. +Grok has none: its login must be in the worker user's HOME +(`~/.grok/auth.json`), as the bench sets it up. + +**The file tools run as the worker.** `read_file`, `write_file`, `edit_file`, +`list_dir`, `grep` and `inspect` are carried out by a small helper process +(`dist/fs-helper.js`) that runs as the worker user. A read the worker could +not do itself fails with `EACCES`, symlinks included, because the kernel +checks the path as that user rather than Maat checking the name. Files the +worker writes are owned by the worker. + +**Maat's records leave the project while the job runs.** The journal, +receipts (including the full twins), the integrity ledger, `out/`, exuviae, +judgment cases, the mission contract and state, and Maat's temp files all +move to a state dir: + +- `MAAT_STATE_DIR` if set, otherwise +- `/var/lib/maat/` when Maat runs as root, otherwise +- `~/.local/state/maat/` + +The dir is mode 700 and owned by Maat. `` includes 48 random bits. +`TMPDIR` points into it, so reference tries (`ref-try-*`), the drafter's +scratch dirs, the copy-on-run trees for hidden checks (`maat-check-*`) and +the judge's own temp files are private too. When the job starts, records +from earlier jobs are copied out of the project's `.maat/` so the hash chains +continue, and a mission's contract, features and state are moved out of the +task folder. That copy is read, and the contract removed, by the file helper +running as the worker (`fs-helper.js pack`); Maat gets back regular files and +folders by name and writes them into its own state dir. Symlinks and other +special files in the project's `.maat/` are skipped, so nothing in the state +dir can point back into the worker's reach or out to a file of root's. + +These stay in the project: `.maat/done.yml`, because a person wrote it, and +`.maat/bg/`, which holds the worker's own background-job logs. The worker +makes those itself: a background job starts as the worker with a shell that +creates the folder and opens its log, so the log is opened with the +worker's permissions and Maat never opens a path in the worker's tree. +`.maat/mission/library/` also stays, because the worker writes it. A spilled +output (`.maat/out/.txt`) is still readable through `read_file`: Maat +serves its own masked copy of the worker's output. The worker cannot `cat` +it from bash. + +**When the job ends, the records come back.** `maat run`, `maat ask` and +`maat mission run` copy the state dir (except `tmp/`) into the project's +`.maat/`, so receipts are where people always found them and `maat verify` +checks them there. Maat reads its own state dir and the file helper, as the +worker, writes the copies (`fs-helper.js unpack`), so they are owned by the +worker and Maat writes nothing into the worker's tree. If a copy cannot be +written with the worker's permissions, Maat says so and the records stay in +the state dir, which is always kept. + +**The judge stays Maat's; the checks run as Maat or as the check account.** +Judge and ask subprocesses (OpenCode, a Grok judge, an HTTP judge) run as +Maat with Maat's HOME. If that HOME is readable by the worker, Maat tightens +it to 700 when it owns it and refuses to start otherwise. Without +`--check-user`, hidden checks run as Maat in the copy-on-run tree, never as +the worker; with it, they run as the check account (next section). A check +that ran in place as Maat (a project check, or a +tree too large to copy) can leave files owned by Maat in the project. After +every bar run, those are handed back to the worker, so the worker can keep +editing its own tree. The worker may be changing the tree while that runs, +so it is never walked by path: each folder is opened relative to its parent +with `O_NOFOLLOW|O_DIRECTORY` (`/proc/self/fd//`), ownership is +changed with `fchown` on the open descriptor, and the project itself must be +the folder (device and inode) the job started in. A folder swapped for a +symlink mid-walk fails to open and is skipped; files with more than one hard +link, symlinks, special files and other file systems are left alone. Hand-back +is Linux-only; elsewhere root-made files stay Maat's. Maat's own git calls in the project (snapshots, commits, +`ls-files`, the local exclude file, the brief's probes) run as the worker, +because the repository and its config belong to the worker. Maat does not set +`safe.directory`, so its own git keeps refusing a repository another user +owns. + +## The check account: `--check-user` + +```sh +maat run --worker-user agent --check-user checker --worker-strict ... +``` + +`--check-user ` (or `MAAT_CHECK_USER`) needs `--worker-user`. Task +checks then run as a third account instead of as Maat: hidden checks, drafted +task checks (`--criteria auto`), `--criterion` checks, the reference check +and its try on the untouched project (the compile and probe steps before it, +which run only the reference program, stay Maat's), mission assertions in the bar and at a +milestone seal, and the tries of drafted criteria before the work. A check is +model-written and runs the worker's code, so it no longer runs as root. + +What it guarantees: + +- **The account.** The check account must not be root, Maat's user or the + worker, and its primary group must not contain the worker. Maat runs as + root (it spawns the check with that uid and gid and no supplementary + groups), or has passwordless `sudo -n -u `. +- **The environment is an allowlist.** `PATH`, `HOME`, `LANG` and `TERM`, and + nothing else of Maat's. `HOME` is a fresh, empty folder made for that one + run and removed after it. No provider key, no `MAAT_*` setting, no `TMPDIR` + (the check uses `/tmp`). +- **Its own PID namespace and /tmp.** When Maat is root with `CAP_SYS_ADMIN`, + each check run is started with `unshare --pid --fork --mount-proc`, so it is + the init of a PID namespace with its own `/proc` (it sees none of Maat's or + the worker's processes, and everything it starts dies with it). Inside, an + empty tmpfs is mounted on `/tmp`, `/var/tmp` and `/dev/shm` (except one that + holds its working directory or Maat's state dir), and the check then drops to + its account with `setpriv --clear-groups --no-new-privs --bounding-set=-all`. + Nothing it writes to a temp dir outlives it, so it cannot leave the + reference check where the worker can read it. +- **Its copy is its own.** The copy-on-run tree is made in + `.check` (owner Maat, group the check account, mode 710) and + handed to the check account, so it can build, write caches and commit in it + as it would in the project. The worker is neither owner nor group of that + folder, so it cannot enter it. +- **The reference check is readable by the check account and not the + worker.** Its programs (`check.py`, `second.py`, `driver.py`) and its + snapshot of the untouched project live in the same check folder, group the + check account, folders 750 and files 640. + +Checks that must run in the project itself run as the **worker**, because the +tree is the worker's: a project's own `done.yml` command checks, a task check +whose tree was too large to copy, and the mutation builtin's runs. They get +the worker's scrubbed environment, and with `CAP_SYS_ADMIN` their own PID +namespace and private /tmp per run too (a hidden check that fell back to +running in place is not visible in the worker's process list). Nothing in the +project is then made by Maat, so there is nothing to hand back. + +The check account's folder must be reachable: with the default state dir +(`/var/lib/maat/`), Maat opens `/var/lib/maat` to 711 when it made +it (each session's own folder stays 700). With `MAAT_STATE_DIR`, a folder +above it closed to the check account means the check account cannot be used +(Maat says so; `--worker-strict` refuses). In sudo mode Maat cannot chown, so +the check gets read-only copies and the default state dir under Maat's HOME +(700) is not reachable: set `MAAT_STATE_DIR`. + +## `--worker-strict` and the isolation line + +`--worker-strict` refuses to start, with exit 2 and a message naming what is +missing, unless all three are in place: the worker account, the check account +(`--check-user` must be given and usable) and the PID namespace (for the +worker, and for each check run with its private /tmp). It also refuses +`MAAT_WORKER_PIDNS=0`. + +Without it, Maat carries on with whatever could be set up: a check account +that cannot be used leaves the checks running as Maat, a missing namespace +leaves the process list visible, and a worker account that cannot be used +leaves the whole job unseparated (unless `MAAT_WORKER_PIDNS=1`, which still +refuses). Each case is said on stderr. Every receipt and the journal (one +`note` entry with `kind: "isolation"`) then carry one line with the isolation +actually in effect, for example: + +``` +isolation: worker uid 1001, check uid 1002, pid namespace on +isolation: worker uid 1001, check uid none (task checks run as Maat, uid 0), pid namespace off +isolation: none (worker tools and checks run as Maat, uid 0: no such user: agent) +``` + +The line is there whenever `--worker-user` was given, strict or not, and +absent otherwise. + +## The process list + +`ps` shows every process's command line to every user unless `/proc` is +mounted with `hidepid=2` (`hidepid=invisible`). Hidden checks are commands, +so while one runs as Maat, a worker that can list processes can read it. +`hidepid` cannot be relied on: it is a mount option of the host or +container, and most container runtimes do not set it. + +Maat's own command line is plain (`maat`), because the process title is +replaced at startup. + +When Maat runs as root with `CAP_SYS_ADMIN` and `unshare`, `nsenter` and +`setpriv` are installed (util-linux), it starts one PID namespace with a +private `/proc` for the job. Every command the worker triggers runs inside +it, and so does the ACP agent with everything it starts. Inside, the worker +sees only its own processes. Background servers it starts keep running +between calls, because the namespace lives as long as Maat does. The worker +enters the namespace with `--no-new-privs` and an empty capability bounding +set, so the capability that created the namespace never reaches it, not even +through a setuid binary. + +- `MAAT_WORKER_PIDNS=0` turns it off; `=1` requires it (Maat refuses to + start without it). +- Without it, Maat says so on stderr. The fix is either to mount `/proc` + with `hidepid=2` (the host's or the container's), or to give Maat root and + `CAP_SYS_ADMIN`. For Docker: `docker run --cap-add=SYS_ADMIN ...`. Docker's + default seccomp and AppArmor profiles allow it on OrbStack and on current + Docker Engine. + +Process memory needs nothing extra. `/proc//mem` and ptrace need the +same uid (and `CAP_SYS_PTRACE`), and a separate PID namespace hides the +process entirely. + +## The bench + +`bench/local/container/run-in-container.sh` turns this on by default: + +- `run.py` runs Maat as root with `--worker-user agent --check-user checker`. + The image has both users: `agent` (uid 1001) and `checker` (uid 1002, its + own group, no home). `BENCH_PRIVSEP=0` runs the whole of Maat as `agent`, + as before. +- The container gets `--cap-add=SYS_ADMIN` for the PID namespace. + `BENCH_PIDNS=0` drops it. +- The worker's Grok credential is copied to `/home/agent/.grok`. A Grok + judge's credential is copied to `/root/.grok` and the OpenCode judge's to + `/root/.local/share/opencode`. `/root` is mode 700. +- Tasks run in a container-local `/var/lib/bench-work` (mode 711), so a + worker can reach its own task folder by name but cannot list the others. + Each task's log is written mode 600, and after grading the task folder is + locked to root (700). This stops a later task (a repeat of the same task, + the other arm of a pair) from reading the checks an earlier one released. + Everything is copied to `/work` (`BENCH_EXPORT`) when `run.py` ends. `/work` + is a host bind mount, and on OrbStack and Docker Desktop a bind mount + ignores `chown` and does not enforce file modes for other users, so a lock + placed there would not hold. +- The graders and reference solutions stay root-only, as before. The graders + (and `crosscheck.py`'s re-grades and check re-runs) work on a root-owned + copy whose repositories are cut to their format lines, without hooks or + attributes; nothing sets `safe.directory`. + +To check it from outside a running job: + +```sh +docker exec maat-bench- sh -c 'ls /var/lib/maat' +docker exec maat-bench- runuser -u agent -- cat /var/lib/maat//log/ # Permission denied +``` + +## Known limitations + +- **The network is shared between accounts.** The worker, the check account + and Maat use the same network. A check (which runs the worker's code) can + send what it can read, the reference check included, to anything it can + reach, and the worker can fetch it from there. Privilege separation is + about the local machine; run the container with no network, or a + restricted one, to close this. +- **Snapshot and mutation code still read worker files by path.** Maat, as + root, copies the worker's tree for each check (`src/scratch.ts`), snapshots + it for the reference check (`snapshotProject`), lists it to see what a + command created, and the mutation builtin reads and rewrites source files + in the project by path. Those reads follow what the worker left there (a + symlink is copied as a symlink, but a mutation target is opened by name). + Only the hand-back walk and the records copy work by descriptor or as the + worker. +- **The agent user's HOME and /tmp are shared between bench tasks in one + container.** Every task in a bench container runs its worker as the same + `agent` user, with the same `/home/agent` and the same `/tmp` (the worker's + own PID namespace has no private /tmp). A later task's worker can read what + an earlier one left there. Task folders and logs are locked after grading; + HOME and /tmp are not cleared between tasks. +- In sudo mode (Maat not root) there is no PID namespace, for the worker or + the checks. The environment is passed on sudo's command line (already + scrubbed for the worker, allowlisted for checks). +- The ACP worker's MCP connection to Maat's tools is a loopback port behind a + per-session bearer token held by the worker's own agent. Through it the + worker reaches only Maat's tools, which run as the worker. +- Off Linux (macOS desktop) nothing changes. `--worker-user` works on any + POSIX system where Maat is root, but without a PID namespace. diff --git a/docs/provider-terms.md b/docs/provider-terms.md index e7a0c8b..a8018ad 100644 --- a/docs/provider-terms.md +++ b/docs/provider-terms.md @@ -36,6 +36,20 @@ Useful xAI references (check the live pages for current text): - [Terms of Service — Enterprise](https://x.ai/legal/terms-of-service-enterprise) - [Acceptable Use Policy](https://x.ai/legal/acceptable-use-policy) +## OpenCode Zen (`opencode://zen`) + +Maat can run the official `opencode` CLI as a worker or judge, for **OpenCode +Zen models only** (`opencode/...`, e.g. the free Big Pickle).
