Create a native task assigned to +**Codex DGX** (`#V#codex_dgx`), with Michael as its creator and report recipient. +Create it from the relevant conversation's Tasks panel when context matters, +and invite Codex DGX to that conversation. Assignment grants access to the task; +the conversation invitation grants access to the source transcript separately. + +The worker checks hourly, starts at most one coding run per check, and sends a +pickup message followed by a result or question through Von direct messages. +An empty check makes no model request. Each task has its own Git worktree. Each +execution is a fresh subscription-backed Codex session, using the retained +worktree, task and previous result for continuity. + +Answer a question in its task message thread or add a comment to the task. +The current Messages UI groups messages by participants: once it contains +several task threads it may omit a thread identifier on a general reply. In +that case use a task comment to keep the reply unambiguous. General inbox +messages do not create new coding assignments in this pilot. + +The initial DGX GitHub account has read access to Von only. The worker can +produce and test local changes; tasks requiring publication remain blocked +with their changes retained until suitable GitHub credentials are configured. +It must not claim that local code is published. Deployment of the public web +server is outside this worker's initial execution profile. + +## Controller and authority + +[`scripts/codex_von_worker.py`](../../scripts/codex_von_worker.py) uses the +existing canonical task, membership, conversation and direct-message services. +An operator-owned config binds the actor, organisation, delegator, source +repository, state directory and Codex launcher before processing any task. +The worker selects tasks assigned to that actor, created by that delegator, +in that organisation, and reporting to that delegator or with no explicit +report recipient. Retrieved task or model text cannot change these selectors. + +Conversation concept identities remain owner-private. When access-control +redaction hides a task's source relation, the adapter matches only actual +invitations addressed to its actor against an access-controlled existence query +on that task. It accepts pending invitations only from the configured delegator +in the configured organisation. The canonical transcript handler still checks +membership and accepted sharing. Missing context is reported explicitly; the +model decides whether the task text alone is adequate. + +The controller writes task progress/evidence and sends idempotent direct +messages, reading effects back before recording delivery. It freezes the result +message intent before sending, so an interrupted report can be reconciled. +An unsuccessful process, absent exit receipt or invalid structured result is +blocked rather than completed. Reassignment/cancellation discovered after a run +prevents the worker from changing the task state. Its result still goes to the +original configured delegator. This is a single-host worker, not a distributed +claim/lease protocol. + +The Codex process uses `workspace-write` sandboxing and an explicit non-Sol +model. Its environment omits the controller's Mongo credentials and unrelated +API keys. Its MCP connection is disabled during assigned executions; selected +task/conversation context is supplied in a local file. The operational prompt +is a versioned input for this external Codex worker, not a duplicate of a +Vontology-governed production prompt. This pilot uses the trusted SAIL local +operator profile; it is not a hardened boundary against a hostile host user. + +## Installation + +Use a dedicated Codex home with ChatGPT subscription login, an explicit +non-Sol model, and a working native Linux sandbox. Keep the API-key Codex home +separate. The launcher should unset `OPENAI_API_KEY` and `CODEX_API_KEY`, set +the dedicated `CODEX_HOME`, and execute the installed official Codex CLI. +Validate an actual agent-issued shell command before enabling polling. + +Install the script and adjacent `codex_von_worker_prompt.md` from the same +reviewed revision. Run them with the project's PDM-managed Python environment. +A JSON config has these fields (paths are operator-selected): + +```json +{ + "agent_id": "#V#codex_dgx", + "delegator_id": "#V#michael_witbrock", + "organisation_id": "#V#university_of_auckland_strong_ai_lab", + "state_root": "/home/mjw/.codex-von-worker/worker-state", + "source_repo": "/home/mjw/von-codex-runtime", + "codex_command": "/home/mjw/.local/bin/von-codex", + "model": "gpt-5.6-terra", + "python_environment": "/home/mjw/Von/.venv" +} +``` + +The optional `python_environment` provides the existing PDM environment via a +worktree symlink. Dependency changes needing writes outside the sandbox may +require operator preparation. Do not replace `pdm.lock` or synchronise a Von +project with another dependency manager. + +The DGX operator wrapper reads the existing web runtime's database credential +in-process, checks that the configured database target still matches the +public website, binds the worker config, and suppresses event-driven workflow +launches in that controller process. It does not alter the web process's +configuration. Store credentials, configuration and operational state outside +the repository with owner-only permissions. Never log the database URI. + +On a host with an active cron service, install an hourly entry invoking the +wrapper and redirecting stdout/stderr to an owner-only log. An example schedule +is `17 * * * *`; preserve any other existing crontab entries. Run the exact +entry manually before installation. No Codex app session or SSH connection +needs to remain open. The controller uses a nonblocking file lock and passes +it to its child so concurrent invocations do not start overlapping work. + +## Operation and evidence + +On the pilot DGX, the wrapper is +`/home/mjw/.codex-von-worker/poll-von`. `worker-state/tasks/` records checkpoints; +`worker-state/runs/` contains input context, Codex JSONL events, the structured +result and exit receipt; `worker-state/worktrees/` retains coding results. +Keep these private: they can contain authorised conversation excerpts. + +To pause pickup, remove only the tagged worker crontab entry. To retry a failed +run, inspect its retained work and set the Von task back to pending. Do not +delete worktrees to force a retry. A full host crash preserves files and makes +the next poll report an incomplete run; it does not automatically repeat +potentially consequential code-side effects. If the controller cannot reach +Von, its error remains in the operator log and reconciliation waits for a +later check. There is no separate out-of-band outage alert in this pilot. + +Acceptance is a task-to-code-to-message result on the actual DGX, including +question/reply continuation and source context that is unavailable before an +invitation. The targeted tests cover empty polls, wrong task scope, failed +processes/results, report replay, reassignment, invitation lookup, and Git +preparation failure. Use the Jira decision surface for current installation, +runtime receipts and remaining publication work; a repository merge alone does +not prove that a scheduler or public runtime was activated. diff --git a/scripts/codex_von_worker.py b/scripts/codex_von_worker.py new file mode 100755 index 000000000..41f77cb66 --- /dev/null +++ b/scripts/codex_von_worker.py @@ -0,0 +1,559 @@ +#!/usr/bin/env python3 +"""Single-host Codex task worker using Von's canonical services. + +Run with the project's PDM environment and an operator-owned JSON config. +The controller owns identity, polling and reporting;

Keep the summary useful +to Michael without requiring him to read raw logs. diff --git a/tests/backend/test_codex_von_worker.py b/tests/backend/test_codex_von_worker.py new file mode 100644 index 000000000..117fe2f6a --- /dev/null +++ b/tests/backend/test_codex_von_worker.py @@ -0,0 +1,244 @@ +"""Bounded authority and interrupted-run acceptance for the external worker.""" + +import importlib.util +import json +from pathlib import Path +from types import SimpleNamespace + +import pytest + +spec = importlib.util.spec_from_file_location( + "codex_von_worker", + Path(__file__).resolve().parents[2] / "scripts/codex_von_worker.py", +) +worker = importlib.util.module_from_spec(spec) +spec.loader.exec_module(worker) + + +@pytest.fixture +def config(tmp_path): + return { + "agent_id": "#V#worker", + "delegator_id": "#V#owner", + "organisation_id": "#V#org", + "state_root": str(tmp_path), + } + + +def task(config, **changes): + return { + "task_concept_id": "#V#task", + "title": "A coding task", + "status": "pending", + "assignee_concept_id": config["agent_id"], + "created_by_concept_id": config["delegator_id"], + "organisation_concept_id": config["organisation_id"], + **changes, + } + + +@pytest.mark.parametrize( + "changes", + [ + {"assignee_concept_id": "#V#other"}, + {"created_by_concept_id": "#V#other"}, + {"organisation_concept_id": "#V#other"}, + {"report_to_concept_id": "#V#other"}, + ], +) +def test_wrong_task_authority_never_launches(config, changes, monkeypatch): + monkeypatch.setattr(worker, "launch", lambda *a: pytest.fail("unauthorised launch")) + api = SimpleNamespace(pending=lambda: [task(config, **changes)]) + worker.tick(config, api, 0) + + +def test_empty_poll_has_no_model_or_message(config, monkeypatch): + monkeypatch.setattr( + worker, "launch", lambda *a: pytest.fail("empty poll launched Codex") + ) + worker.tick(config, SimpleNamespace(pending=list), 0) + + +@pytest.mark.parametrize( + "exit_code,output", + [ + ( + 1, + { + "status": "completed", + "summary": "Done", + "evidence": "check", + "question": "", + }, + ), + (0, {"status": "completed", "summary": "Done", "evidence": "", "question": ""}), + (0, "malformed"), + ], +) +def test_process_or_output_failure_cannot_complete(tmp_path, exit_code, output): + worker.write_json(tmp_path / "exit.json", {"returncode": exit_code}) + worker.write_json(tmp_path / "result.json", output) + state = {"run_dir": str(tmp_path)} + worker.recover_result(state) + assert state["phase"] == "reporting" + assert state["result"]["status"] == "blocked" + + +def test_interruption_without_exit_receipt_blocks_and_preserves_work(tmp_path): + (tmp_path / "patch.py").write_text("print('retained')") + state = {"run_dir": str(tmp_path)} + worker.recover_result(state) + assert state["result"]["status"] == "blocked" + assert (tmp_path / "patch.py").exists() + + +def test_waiting_for_unchanged_input_does_not_spend_model_calls(config, monkeypatch): + current = task(config, status="blocked") + inputs = {"description": "work"} + path = Path(config["state_root"]) / "tasks" + path.mkdir() + worker.write_json( + path / (worker.fingerprint("#V#task")[:16] + ".json"), + { + "task_id": "#V#task", + "phase": "waiting", + "input_hash": worker.fingerprint(inputs), + }, + ) + api = SimpleNamespace(pending=lambda: [current], inputs=lambda t: inputs) + monkeypatch.setattr( + worker, "launch", lambda *a: pytest.fail("unchanged input launched") + ) + worker.tick(config, api, 0) + + +def test_report_retry_has_same_message_intent_after_task_completed(config): + api = object.__new__(worker.Von) + api.config = config + current = task(config, status="in_progress") + api.task = lambda _: current + sent = [] + api.send = lambda t, key, content: sent.append((key, content)) or "#V#message" + api.tasks = SimpleNamespace( + update_task_fields=lambda *a, **kw: None, + update_task_status=lambda tid, status, **kw: current.update(status=status), + ) + state = { + "task_id": "#V#task", + "attempt": "run", + "phase": "reporting", + "result": { + "status": "completed", + "summary": "Done", + "evidence": "Validated", + "question": "", + }, + } + api.finish(state) + #
