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. + +## 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. +Uncertain creation or tool execution requires reconciliation. This is bounded +Turn execution, not full crash-resumable fleet supervision or a distributed +authority service. + +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 cloud coordinator asks two registered local dsh workers to analyze a filing +and its correction, reviews independently accepted evidence, and writes a +combined report. There is no `phase` argument or script that selects the next +business step. The model chooses delegation questions and order through three +MCP tools: `read_assignment`, `delegate`, and `write_report`. + +This is a bounded composition example for the optional +[Ark Turn adapter](../../packages/loopx-ark-turn/README.md), not a fleet scheduler. +It prepares an isolated synthetic Goal, roster and worktrees, then launches one +coordinator Turn. Each delegation uses the existing Todo and `turn run-once +--host dsh` entrypoints. The coordinator uses `--host generic-cli` with the same +Turn request/candidate and independent acceptance boundary. + +## Run + +From a matching source checkout, install the optional providers into the same +interpreter. Default LoopX installations do not download either SDK. + +```bash +uv sync --extra test --extra deepseek-harness +uv pip install --python .venv/bin/python -e packages/loopx-ark-turn +``` + +Configure `ARK_API_KEY`, `ARK_MODEL_ID`, `ARK_ENVIRONMENT_ID` and +`DEEPSEEK_API_KEY` in the environment. The Ark Environment must already exist +and belong to the operator; the demo never creates or deletes it. The local +dsh profile defaults to `deepseek-v4-flash@high`; override `--dsh-model` explicitly +for another qualified local profile. Credentials are not command arguments. +The adapter forwards the local worker credential only to the trusted demo MCP +process, never to cloud tool arguments/results. + +Choose a **new** private disposable directory outside the source checkout's +tracked files. Runs may invoke up to eight local worker attempts and one cloud +session, with a 20-minute outer bound; provider usage can accrue on rejected +attempts too. Do not point this demo at an active Goal or research workspace. + +```bash +uv run --no-sync --extra test python examples/managed-research-team/demo.py \ + run "$DEMO_ROOT" --model "$ARK_MODEL_ID" --environment-id "$ARK_ENVIRONMENT_ID" + +uv run --no-sync --extra test python examples/managed-research-team/demo.py \ + validate-report "$DEMO_ROOT" +``` + +The launcher exits unsuccessfully unless the lead Turn commits validated +progress. Inspect `lead/report.json`, `accepted/`, `turns/`, `lead-turn.json` +and `provider-receipts/` inside that private directory. These local artifacts +are not public demo fixtures or publishable run logs. Inspect canonical state +with the existing CLI, using absolute values for the two local paths: + +```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 +``` + +The host receipt's tool ACK only means a result reached the provider. Each +worker must pass the independent validator and canonical Turn writeback; the +lead must then adopt all four exact artifact hashes and pass a separate +aggregate validator. The `accepted/` files are evidence copies produced by +this trusted example service, not an alternative Todo/lease/acceptance store. + +## What the scenario checks + +| Evidence | Initial | Corrected | Required interpretation | +| --- | --- | --- | --- | +| Cash from operations | 120 | 105 | Correction changes the consumed input | +| Capital expenditure | 30 | 30 | Raw FCF becomes 90 → 75 | +| Receivables sold, included in cash | 50 | 50 | Normalized FCF becomes 40 → 25 | +| Current vs prior fiscal period | H1 vs FY | H1 vs FY | Neither positive nor negative growth is established | +| Repost of the issuer | Same source | Old figures retained | One independent family; stale only after correction | + +Worker outputs bind the input bytes by SHA-256. The final report binds each +worker/revision output by hash, incorporates the correction and checks the +semantic conclusions. A valid-looking report with a missing/unaccepted worker, +stale dependency hash, altered input, wrong calculation or unsupported growth +claim is rejected. Tests mutate these conditions independently of model output. + +## Qualification recorded for this slice + +One final local run passed through the real public Ark API (`arkruntime 0.8.0`, +`doubao-seed-2-1-pro-260628`) and real dsh (`deepseek-harness-sdk 0.1.5rc1`, +`deepseek-v4-flash@high`). Four worker Turns and the lead Turn committed +`validated_progress`; a separate report readback passed. The cloud model used +six local tool calls: assignment read, four delegations, and report submission. +The host confirmed its session and Agent absent; the experiment owner separately +deleted its disposable Environment. No model calls run in CI. + +Earlier qualification attempts failed on event identity decoding, pagination, +missing local runtime and ambiguous source-count scope. They were not accepted +as successful work. The fixes use the custom-tool event id as result correlation, +opaque `next_page` tokens, a local dependency preflight, explicit current-period +source counting and actionable field-level rejection. An interrupted canary +also cleaned its owned resources; a cleanup retry retired a known pending +session without repeating work. Uncertain *creation* still requires manual +reconciliation. This is one bounded success after repairs, not a reliability, +throughput or arbitrary-scale claim. + +Deterministic checks use the real SDK over synthetic HTTP fixtures plus a real +stdio MCP process. They cover input/capability mismatch, duplicate and changed +event identities, pagination beyond 200 events, timeout/cancellation, competing +starts, cleanup-only replay and semantic/dependency mutations. Both existing +DSH CLI smokes are byte-identical against the pre-change baseline; dropping the +Turn identity in a disposable baseline makes the same oracle reject writeback. + +## Boundaries and cleanup + +The model does not choose an executable, credential, workspace, roster or +validator. The trusted MCP service binds the caller and permits only the two +workers and two input revisions. It serializes delegated Turns and permits two +attempts per worker/revision. It deliberately does not implement a new queue, +Inbox, lease owner or continuation mechanism. The three Agent identities and +all canonical work remain in LoopX; ephemeral provider sessions are execution +resources. MCP tool execution uses local OS permissions and requires a trusted +server; the cloud sandbox does not isolate local subprocesses. + +This example qualifies a managed coordinator calling local workers within one +bounded Turn. It does not establish arbitrary team size, parallel fairness, +multi-level recursive launch, restart recovery of the coordinator, live +steering, distributed authority, or persistent Chat/Lark/desktop integration. +Those remain with the existing team/session RFCs. The roster and acceptance +are fixed by the operator; there is no claim of autonomous permission creation. + +On normal completion the adapter deletes its owned Ark session and Agent and +confirms absence. The configured Environment remains. On failure inspect the +private provider receipt and use the adapter's cleanup operation for known +resources; unresolved creation requires operator reconciliation. Stop before +removing the disposable directory, and retain incomplete receipts. Removing +this example or its explicit host command disables it; it installs no monitor +or recurring automation and modifies no existing Goal. + +## 中文操作与能力说明 + +这是一次有界的真实协作：云端协调员自行决定问题和委派顺序，本地分析员、核验员 +分别处理初始数据和修订数据，然后云端综合四份独立验收的产物。启动脚本只准备 +隔离环境、注册名单并启动一次 Turn，没有人为输入 `phase` 来推进业务流程。 + +按上面的命令安装两种可选 SDK，配置模型、已有云端 Environment 和凭据，再使用 +新的私有目录运行。`validate-report` 会重新检查计算、期间可比性、来源独立性、 +修订采用和四份依赖的哈希。工具返回、worker 通过验收、总报告通过验收是不同事实。 +所有演示数据都是虚构数据，不涉及真实证券建议、交易或私有研究资料。 + +这提供了可复用的本地/云端受控工作单元，以及“managed Agent 可以继续委派”的 +实际调用样例。它还不是完整数字团队产品：持久 Inbox/queue/steer、自动扩缩容、 +多层级恢复及前端/Lark 团队入口仍需沿现有 RFC 完成。本次不会改变管家默认执行器 +或看板。正常结束会清理本次云端 Agent 和会话，不删除你配置的 Environment；失败 +时保留私有回执，按适配器说明检查和清理，不能用删除回执来掩盖未清理资源。 diff --git a/examples/managed-research-team/demo.py b/examples/managed-research-team/demo.py new file mode 100644 index 0000000000..6b28fcadff --- /dev/null +++ b/examples/managed-research-team/demo.py @@ -0,0 +1,187 @@ +#!/usr/bin/env python3 +"""Prepare and launch one bounded autonomous collaboration;

Model selection belongs to an Agent's execution +profile and binding, independently of whether that Agent coordinates others. +Reuse the existing managed execution profile, subagent launch preferences and +profile editor; the steward's machine defaults are one caller's defaults, not +the universal configuration owner. A model change does not create a new logical +Agent or grant permission to launch one. + +| Step | Owner and required observation | +| --- | --- | +| Discover choices | The selected executor/provider adapter reports model IDs, supported parameters, capability limits, discovery scope and freshness. Keep provider catalog presence, managed-host compatibility and account authorization separate; unknown or failed discovery is not an empty supported list. | +| Request and resolve a profile | The shared typed TS boundary validates caller scope, allowed profiles, budget constraints and explicit configuration precedence. Retain the requested model and parameters separately from resolved values and their sources. SDK/network discovery remains in the adapter; do not copy selection or admission rules into each Python launcher. | +| Create or attach | Creation uses the resolved profile through the selected adapter. Attachment observes the existing host's actual profile; it cannot silently change its model, start a replacement executor or claim that a requested preference already took effect. Repeated creation reuses the existing identity/binding contract. | +| Start and read back | Bind the profile revision to the execution generation and read back the provider-reported model and effective parameters. A visible catalog row or successful Agent-definition creation does not establish that an inference session can run. A mismatch or unsupported option produces an actionable failure, never an implicit model fallback. | + +Parameter support is provider-specific: the same reasoning-effort label need +not have the same meaning across hosts, and speed, thinking mode, context limits +and tool support are not universal knobs. Use a small common selection contract +with validated provider-owned options rather than a core list of vendor models +or one global parameter enum. Credentials remain in the selected provider's +credential scope and never enter an Agent profile or public projection. + +Mutable model aliases require explicit readback. Record a resolved version only +when the provider exposes it; otherwise record that the backing version is +unknown rather than treating the alias as a reproducible snapshot. Profile +changes use the existing binding revision/generation and rebind boundary; +running work retains its admitted profile until a qualified transition occurs. +Changing the parent profile does not silently change existing children. An +authorized child coordinator may choose only within its inherited profile and +budget scope, using the same operation as the lead. + +The next implementation slice must connect discovery, selection, creation or +attachment, launch and readback for both a local and a cloud executor. Qualify +unsupported parameters, stale discovery, unavailable authorization, retry, +mutable aliases, and profile changes during active work. Reuse the existing +CLI, frontend and Lark configuration owners/projections where affected; a +backend field alone does not complete that user journey.

A mixed run recovered after a tool request timeout: concurrent -relaunch was refused, the original task completed, and the coordinator retrieved -its result and repaired the report's dependency hash. Coordinator tool waits now -cover the bounded child Turn plus its completion/readback; rejection feedback -names the mismatched dependency. Uncertain *creation* still requires manual -reconciliation. These are bounded successes after repairs, not reliability, -throughput, cancellation-supervision or arbitrary-scale claims. - -A final mixed run rejected a malformed source list and a cloud execution -timeout; the local lead retried both and reached five independently verified -completions. The timed-out cloud attempt left a known pending session, which -the experiment owner reconciled and confirmed absent before deleting the -Environment. The child host deadline now reserves room beyond Ark execution -for deletion and absence checks. This does not guarantee immediate provider -deletion or replace receipt-based reconciliation. - -Deterministic checks use the real SDK over synthetic HTTP fixtures plus a real -stdio MCP process. They cover input/capability mismatch, duplicate and changed -event identities, pagination beyond 200 events, timeout/cancellation, competing -starts, cleanup-only replay and semantic/dependency mutations. Both existing -DSH CLI smokes are byte-identical against the pre-change baseline; dropping the -Turn identity in a disposable baseline makes the same oracle reject writeback. +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 model does not choose an executable, credential, workspace, roster or -validator. The trusted MCP service binds the caller and permits only the fixed -worker/revision assignments. It serializes delegated Turns and permits two -attempts per worker/revision. It deliberately does not implement a new queue, -Inbox, lease owner or continuation mechanism. The configured Agent identities and -all canonical work remain in LoopX; ephemeral provider sessions are execution -resources. MCP tool execution uses local OS permissions and requires a trusted -server; the cloud sandbox does not isolate local subprocesses. - -DSH intentionally scrubs credential-shaped variables from MCP subprocesses. -The local lead's Cordis patch explicitly forwards the two provider credentials -using `!!js process.env.NAME` references. Only variable names are written to -configuration; values stay in the local execution environment and never enter -cloud tool arguments/results. The local service refuses startup without that -explicit environment. Ark worker MCP processes receive neither provider key. - -The main profile exercises a local DSH coordinator with mixed DSH/Ark members; -the secondary profile exercises a cloud coordinator calling local workers. -Cloud members only receive their assigned input, authorized upstream artifact -and output tool; no arbitrary filesystem or shell tool is exposed. -This does not establish arbitrary team size, parallel fairness, -multi-level recursive launch, restart recovery of the coordinator, live -steering, distributed authority, or persistent Chat/Lark/desktop integration. -Those remain with the existing team/session RFCs. The roster and acceptance -are fixed by the operator; there is no claim of autonomous permission creation. - -On normal completion the adapter deletes its owned Ark session and Agent and -confirms absence. The configured Environment remains. On failure inspect the -private provider receipt and use the adapter's cleanup operation for known -resources; unresolved creation requires operator reconciliation. Stop before -removing the disposable directory, and retain incomplete receipts. Removing -this example or its explicit host command disables it; it installs no monitor -or recurring automation and modifies no existing Goal. +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.
