Ark is an [optional execution provider](../../packages/loopx-ark-turn/README.md). +The example supplies domain inputs, validators and operator bindings; it does +not implement a separate scheduler or task database. + +## Run + +From a matching source checkout, install both optional providers into the same +interpreter. Node 24.21 or later qualifies the File/SQLite example. + +```bash +uv sync --extra test --extra deepseek-harness +uv pip install --python .venv/bin/python -e packages/loopx-ark-turn +``` + +Set `ARK_API_KEY`, `ARK_MODEL_ID`, `ARK_ENVIRONMENT_ID` and `DEEPSEEK_API_KEY` +in the environment. The Ark Environment must already belong to the operator; +this launcher never creates or deletes it. The local model defaults to +`deepseek-v4-flash@high`; select another profile with `--dsh-model`. + +Choose a **new private disposable directory**. Never point this example at an +active Goal or research workspace. The canonical Goal quota governs admission; +this version no longer has the old demo-only two-attempt counter. Each binding +has a finite deadline, and rejected attempts may still incur provider usage. +The local lead and nested cloud coordinator have up to 20 minutes each; other +members have five-minute host budgets, including cleanup. These are per-binding +limits, not a fleet-wide currency cap. + +```bash +uv run --no-sync --extra test python examples/managed-research-team/research_team.py \ + run "$DEMO_ROOT" --model "$ARK_MODEL_ID" --environment-id "$ARK_ENVIRONMENT_ID" + +uv run --no-sync --extra test python examples/managed-research-team/research_team.py \ + validate-report "$DEMO_ROOT" +``` + +The launcher succeeds only after the lead's validated Turn and canonical Todo +completion. Read `completion.json`, `lead/report.json`, `lead-turn.json`, the +private collaboration execution receipts and `provider-receipts/`. They are local +experiment records, not publishable fixtures. Canonical readback: + +```bash +uv run --no-sync --extra test python -m loopx.cli \ + --registry "$DEMO_ROOT/registry.json" --runtime-root "$DEMO_ROOT/runtime" \ + --format json todo list --goal-id synthetic-managed-research + +uv run --no-sync --extra test python -m loopx.cli \ + --registry "$DEMO_ROOT/registry.json" --runtime-root "$DEMO_ROOT/runtime" \ + --format json goal-acceptance verify --goal-id synthetic-managed-research --execute +``` + +## Collaboration path + +The primary `local-led` profile has four independently accepted member tasks: + +- The local lead delegates initial-filing analysis to local DSH `local-analyst`. +- Ark `cloud-reviewer` independently verifies that completed artifact and adopts + its exact hash. Starting early cannot bypass the prerequisite's acceptance. +- Ark `cloud-analyst` receives the corrected-filing task and itself delegates + independent review to local DSH `local-reviewer`, preserving the parent + request. It waits for acceptance and adopts the returned artifact. +- The local lead reads all four accepted artifacts, resolves the revision and + source distinctions, and writes the combined report with exact dependencies. + +The two branches may run concurrently. The model chooses when to start, what to +ask, whether to repair rejected work and how to synthesize. The host provides +bounded `list_execution_bindings`, `start_delegation`, `wait_delegation`, +`read_delegation` and `resume_delegation` operations. Members independently +`assess_request`; a read, message or tool ACK cannot complete a task. + +The optional `--topology cloud-led` profile retains Ark-to-DSH coordination as +an additional route. It does not substitute for the primary local-led path. + +## Independent acceptance + +| Evidence | Initial | Corrected | Required conclusion | +| --- | --- | --- | --- | +| Cash from operations | 120 | 105 | Consume the correction | +| Capital expenditure | 30 | 30 | Raw FCF is 90 → 75 | +| Receivables sold | 50 | 50 | Normalized FCF is 40 → 25; delta −15 | +| Fiscal period comparison | H1 vs FY | H1 vs FY | Growth is unsupported | +| Repost of issuer material | Same source | Old figures retained | One current-period source family; corrected repost is stale | + +`bootstrap.ts` creates only a fresh disposable canonical runtime and invokes +the production owner configuration API once. It binds four member criteria and +one report criterion. Task instructions, the roster and verifier files are +pinned; a member cannot change its own acceptance. Existing Goals are never +promoted or rewritten by this bootstrap. + +Core delegation asks the TS acceptance owner for the exact task's criteria and +runs those checks as its Turn validator. It then uses ordinary `todo complete`, +which re-executes validation and atomically commits through the same TS owner. +The report separately checks all four canonical completions, current binding +guards, adopted hashes and financial conclusions. All five Todos may be done +while the overall Goal remains active for its owner. + +A member's own peer conclusion is preserved. The delegation result independently +reports canonical acceptance; it does not replace that message or trust a +model-authored `accepted` flag. Saved artifacts and old receipts cannot hide +changed inputs, stale work or modified output. + +## Recovery and validation + +A delegated worker runs independently of the requesting MCP conversation. A +new connection reads its original operation id. Repeating that operation or +resuming a live worker cannot start a concurrent duplicate. After process loss, +recovery uses the original Turn journal. Ark observes its original cloud session +and input; acknowledged tool effects are not repeated. While the host is absent, +cloud computation can continue until it needs a local tool, then waits. +Unknown creation/input acknowledgements or interrupted tool side effects require +explicit reconciliation. Reconnecting does not reset the original deadline. + +Durable tests use the production CLI, File/SQLite authority, TS acceptance and +real stdio MCP, with explicit model substitutes where appropriate. They cover +missing adoption, conflicting operation ids, ungranted actors, concurrent +resume, stale/changed artifacts, prerequisite completion and preserved peer +conclusions. Provider tests restore actual execution checkpoints and verify no +new input or acknowledged tool effect. TS acceptance also runs on isolated real +PostgreSQL; no model calls occur in CI. + +```bash +uv run --no-sync --extra test python -m pytest -q \ + packages/loopx-ark-turn/tests tests/test_collaboration_mcp.py +``` + +Real execution qualification uses the public Ark SDK and DSH with synthetic +materials. A process-loss drill kills the owned worker/Turn/provider process +group after the input ACK, observes cloud `requires_action`, then resumes the +same operation to canonical completion. It confirms one provider receipt, the +same Session and input, and cleanup of owned resources. This evidence is +separate from mocked provider tests and does not establish market-research +quality, arbitrary team scale or attached persistent Codex-task integration. + +## Boundaries and cleanup + +The operator owns Agent registration, bindings, workspaces, executables, +credentials and validators. The model cannot grant new execution authority. +Leaf DSH tools receive no provider credentials. The local lead forwards the +credentials needed for its authorized execution bindings by environment +reference; Ark's local tool process receives the DSH credential only when it +must launch that local member. Ark credentials never enter cloud tool inputs or +results. MCP servers need trusted local OS isolation. + +On normal completion Ark deletes its owned Session and Agent and confirms +absence. Retain private receipts after interruption and use the adapter's +cleanup command for known resources. The Environment remains operator-owned. +Disable admission by removing grants or the explicit execution configuration; +stop/reconcile existing workers before deleting the disposable runtime. + +This slice provides fixed authorized work, dependent artifacts, nested requests +and local recovery. General Agent creation, dynamically derived work, full +inbox/queue/steer, remote authority and Dashboard/Lark configuration remain with +the existing RFC owners.

Set +`ARK_BASE_URL` only for an explicitly chosen compatible endpoint. Keep +`ARK_TURN_STATE` private and outside the task workspace. + +Select this command through the existing +`loopx turn run-once --host generic-cli --iteration-context fresh` interface, +with `--host-command-json` containing the adapter argv above without `--doctor`. +Supply the normal Goal, Agent, project, Todo and independent validation command. +The caller must use a registered LoopX Agent and current work admission. The +adapter's cloud Agent definition and session are execution resources, not new +LoopX identities. + +The envelope action signature is an integrity/coherence hash, not standalone +cryptographic authentication. Invoke the adapter behind the trusted local Turn +executor; it is not a public remote authority endpoint. + +The default managed host and existing `ark-managed-agent` native Goal profile +are unchanged. A fresh cloud session is required for each admitted iteration; +continuation comes from the existing LoopX driver, not an automation prompt. + +## File execution profiles + +For larger tool configurations, use `loopx-ark-turn --config "$ARK_PROFILE"`. +The JSON object uses `Config` fields: `model`, `environment_id`, absolute +`workspace` and `state_dir`, optional `mcp_command` / `tool_names` / `mcp_env` +arrays, and execution/tool timeout and call limits. Keep it outside member +workspaces. Credentials remain environment variables. File profiles and inline +configuration cannot be combined; `--doctor`, `--inspect-turn-key` and +`--cleanup-turn-key` work with either form. File and inline forms resolve to +the same receipt identity; profile changes cannot retarget an existing attempt. + +This compacts the generic CLI invocation without raising its argv limit or the +eight-tool selection limit. The [local delegation interface](../../docs/reference/local-delegation.md) +uses these profiles for both main and nested coordinators. + +## Local tools + +Supply an operator-owned stdio MCP server with `--mcp-command-json` and an exact +`--tool` selection for each exposed tool. Discovery reads every page, rejects +duplicate names, and allows at most eight selected tools. One MCP process is +bound to one Turn; models cannot change its command, selected tools or identity. + +The server receives host-bound `LOOPX_TURN_KEY`, `LOOPX_TURN_GOAL_ID`, +`LOOPX_TURN_AGENT_ID`, `LOOPX_TURN_TODO_ID` and `LOOPX_TURN_WORKSPACE`. Use these +facts to bind the existing collaboration/work services. Tool implementations +must enforce resource scope and authorization; a schema or a coordination role +does not grant authority. MCP servers run with their local OS permissions, not +inside the cloud sandbox. Only connect trusted, appropriately isolated servers. + +The existing `python -m loopx.collaboration_mcp` server can be selected with its +operator-bound registry, runtime, Goal, Agent and workspace argv. Select only +the needed `read_context`, `assess_request`, `request_peer`, `return_result`, +and `consume_peer_result` tools. Those existing tools own semantic requests, +adoption and return; they do not launch workers. This adapter transports their +calls without creating another Inbox or adding manager-specific authority. + +The MCP SDK supplies its platform default environment; additional variables are +opt-in by name using `--mcp-env`. `ARK_API_KEY` is never forwarded. This profile +qualifies text and structured-JSON results only. Unsupported content, oversized +results, unknown tools and exhausted tool-call limits fail explicitly. + +Receiving an external tool request does not complete the work. The adapter +waits through `requires_action`, supplies the correctly correlated result, and +requires `end_turn` plus a typed candidate. Only the independent LoopX validator +can accept the resulting artifact. + +## Lifecycle and readback + +Each attempt creates its own cloud Agent definition and session using the +selected model and exact tool declarations, then deletes both with readback. +The frozen session snapshot must match the model/tool selection and contain no +unexpected skills, remote MCP servers or provider multiagent topology before +input is sent. Historical events are paginated through the public API and +processed only after the input ACK; pre-input idle events cannot finish work. +It never changes or deletes the configured Environment. Private host receipts +retain resource identities, tool-effect status, bounded candidate and provider +usage for reconciliation. Raw model thinking/events and credentials are not +stored. Provider usage is separate from LoopX quota; unavailable usage stays +unknown, and rejected work can still cost tokens. + +Mutating provider requests are not automatically retried. A duplicate exact +request may reuse a completed candidate after resource cleanup; a conflicting +request or incomplete prior attempt cannot silently start another model run. +An interrupted running attempt with a confirmed original input and no uncertain +local effect can resume observation of that exact cloud session. It does not +send the input again, repeat acknowledged tool effects, or reset the execution +deadline. Terminal text is persisted before candidate conversion. While the +host is absent, cloud computation can continue until it needs a local tool; +that call waits for reconnection. An interrupted executing/sending tool, lost +creation/input response or changed tool schema cannot be treated as a safe +restart. Preserve those receipts for reconciliation. This does not install +fleet supervision or provide distributed authority. + +With the same model, environment, workspace, state directory and tool options +as the original invocation, append one of: + +```bash +loopx-ark-turn --inspect-turn-key "$TURN_KEY" +loopx-ark-turn --cleanup-turn-key "$TURN_KEY" +``` + +Inspection is local and credential-free. Cleanup retries deletion of known +attempt-owned resources without launching a model or repeating a local tool. +It returns success only after absence is confirmed. A lost create response +leaves `unknown_creation=reconcile_required`: use the private receipt's exact +resource label to inspect the provider account and resolve ownership manually. +The adapter cannot safely adopt an unknown resource or declare it absent. +Keep that attempt blocked; do not delete arbitrary matching resources or edit +the receipt to make replay look successful. A completed candidate remains +subject to the outer Turn's independent validator on replay. + +To disable, remove the explicit host-command selection and stop any running +adapter before restoring the previous profile. Retain private receipts until +owned cloud resources are confirmed absent. Uninstall with +`uv pip uninstall loopx-ark-turn`; this does not uninstall LoopX or alter work +history.
