It must not be exposed through Higress. + The package ConfigMap is `devflow-worker-packages-v1-3-0`.

Custom DevFlow skills arrive through the shared -package. Worker-specific `agents` instructions state which skill each Worker -owns, preventing responsibility drift. +For a remote server, install +`agentteams/systemd/agentteams-gateway-port-forward.service`. It listens only +on server loopback. Reach it through an SSH local-forward; do not open port +18080 in the public firewall and do not expose MinIO, Tuwunel, the controller, +or the Higress console. + +The hardened live manifest exposes a dedicated gateway endpoint only to +`devflow-locator`, and that `devflow-github-readonly` endpoint contains only +`get_file_contents`. Its custom Skill applies a narrower local scope authorizer +before every call. Reviewer, Coder, and all other Workers receive no GitHub MCP +capability. Configure and verify this boundary with +`scripts/configure_higress_github_readonly.py`; see +[`HIGRESS_GITHUB_READONLY.md`](HIGRESS_GITHUB_READONLY.md) for the pinned API +contract, credential handling, and fail-closed runbook. +The AgentTeams controller maps runtime `devflow-locator` to Higress Consumer +`worker-devflow-locator`; the MCP allowlist uses the latter because that is the +identity bound to the Worker's injected gateway key. +Worker-specific `agents` instructions state which Skill each Worker owns, +preventing responsibility drift. + +AgentTeams supplies the collaboration rooms and delivery lifecycle; DevFlow +does not treat a room message as trusted authorization. Every delivered domain +artifact is wrapped in a digest-bound `HandoffEnvelope`, and the receiving +Worker verifies its consumer and Skill ownership before execution. MCP access +then requires the same Agent + Skill pair. See the +[responsibility matrix and MCP trust model](BOUNDARIES_AND_MCP.md). + +The bundled MCP URL intentionally uses the in-cluster `higress-gateway` +Service. Do not replace it with a public Console or gateway URL in this server +profile. + +## Guarded TeamHarness OpenClaw overlay + +`scripts/teamharness_openclaw.py` installs the TeamHarness MCP behind +DevFlow's process-role guard and merges one small, DevFlow-owned collaboration +contract into the target workspace's `AGENTS.md`. It does not paste the broad +upstream TeamHarness prompts into `AGENTS.md`. Those upstream prompt files are +copied only under `.teamharness/prompts`; the effective workspace instruction +is the section between these stable markers: + +```text + + +``` + +The Leader contract requires an explicit immutable `T1`–`T5` risk tier, a +bounded assignment/ACK exchange, and external Ed25519 approval for T4/T5 +resume, acceptance, and completion. Reporting follows mark, push, then a +`pending=false` readback. The Worker and remote-member contract is deliberately +one-way: idempotently acknowledge, produce the assigned artifact, submit the +same result idempotently, then stop. A retry whose result digest differs is +rejected. It explicitly +forbids project, room, delegation, acceptance, completion, and assignment +message actions. Manager receives an intake-only contract and cannot operate +either lifecycle. + +The effective guarded MCP surface is role-specific: + +| Runtime role | Direct TeamHarness tools | +|---|---| +| Leader | `health`, `message`, `roomflow`, `filesync`, `artifact`, `projectflow`, `taskflow` | +| Worker or remote-member | `health`, `taskflow` | +| Manager | `health`, `message` | + +Worker and remote-member runtimes cannot call `artifact` or `filesync` +directly. They return their assigned artifact through `taskflow`; Leader owns +the bounded final publication/synchronization step. + +The live T4 check currently proves only the fail-closed half of this contract: +Leader created and paused a T4 project, and a resume without an external +approval was rejected with +`approval_denied:approval must contain exactly evidence and signature`. The +ledger remained bound to the project and risk tier with no used nonce, and only +the public verification key was present in the Pods. Before the signed half is +run, the hardened policy must be deployed and a fresh project prepared; the old +target-only confirmation is intentionally obsolete. A human-signed approval +and subsequent approved resume have not yet been executed and must not be +claimed. + +Approval policy schema 1.1 binds the signature to a fixed audience, a unique +64-hex deployment domain, the installed Ed25519 public-key digest, and a +Guard-generated random project incarnation held in the root-only ledger. These +facts, action, project/task identity, risk tier, and canonical target digest +form `approvalRequestDigest`; the human confirmation names that complete +digest. A signature from another deployment, policy key, or reincarnated +project therefore fails before state transition even if project ID and nonce +are copied. + +The current guard implementation and focused tests additionally bind three +different authorities instead of trusting caller-supplied fields: project risk +comes from the root-owned ledger, project source comes from persistent project +state, and task replay/conflict decisions bind `taskId` to submission digests. +For a task room, the guard reads Matrix state, requires a private invite-only +room, and verifies the exact actual member set. Its `invite`/`members` response +is explicitly labeled as the non-creator requested-worker projection; the +full verified membership is represented separately by its count and digest. +The final operator-driven T2 run described below exercised these bindings. It +does not retroactively turn the earlier failed GitHub task into a success; the +failed and successful executions remain separate records. + +`--replace` updates only that marked section and preserves every surrounding +workspace instruction. It rejects unbalanced or duplicate markers. Without +`--replace`, an existing section is an error. Verification requires the exact +role-specific section, matching role facts in `mcporter.json`, the runtime +config, and the externally installed runtime binding, plus a valid hash entry +for `AGENTS.md` in the installation manifest. +It also re-hashes every file recorded by the manifest, so post-install prompt, +Skill, MCP, guard, configuration, or collaboration-contract drift is visible. + +In production, the executable trust chain is not loaded from the writable +role workspace. `mcporter` invokes `/usr/bin/python3` with +`/opt/devflow/teamharness/guarded_server.py`; the adapter and pinned upstream +MCP implementation also live under `/opt/devflow/teamharness`. Runtime +binding, install manifest, approval policy, and the Leader public key live +under `/etc/devflow/teamharness`. The installed files are owned by root and +made read-only, while the replay/risk ledger is the only writable state under +`/var/lib/devflow/teamharness`. The external manifest records and rechecks the +exact guard, adapter, server, runtime-binding, policy, and public-key hashes. +A workspace manifest is retained only as non-authoritative diagnostic +evidence and cannot select `sourcePolicy=test-only` for the production guard. + +This is integrity hardening, not a sandbox: an agent process retaining UID 0 +and sufficient mount/filesystem capability can still replace or remount the +trust chain. Production isolation therefore still requires non-root Workers, +read-only mounts controlled outside the Pod, and a separately privileged +credential broker. + +The accepted source is fixed to AgentTeams commit +`78d0ceda336befa6e62bf89fc1a6b08b965e128d` and TeamHarness `0.1.0`. +Installation fails before modifying a workspace unless all four critical +source files match: + +| File | SHA-256 | +|---|---| +| `plugin.yaml` | `40121114d1f2a5897e90e21f819f34491bd8062eae25634825f9e7b50b61d518` | +| `mcp/server.py` | `cb9971baae3545f440821ecf1fd18c76078962a1fe1591141cc88026bf5b684f` | +| `mcp/message_tool.py` | `03e8fcfcaf002c5d9dd0c023b85bd4d2f4641b83cb59c6d89be08a9c1689c47c` | +| `mcp/roomflow_tool.py` | `db127d550cf9155c133657ab7c89fee48292c07587a061954bd60b4c14991680` | + +PyYAML is optional. When it is absent, the adapter accepts only the +hash-verified upstream `plugin.yaml` and a strict two-space mapping subset for +the runtime config. `member.role` remains mandatory and must equal the install +role; duplicate keys, unsupported YAML structures, embedded runtime +credentials, or ambiguous indentation fail closed. The production CLI has no +hash-bypass flag. + +The runtime name and Pod hostname are distinct identities. For example, +`runtimeName=devflow-lead` maps to +`hostname=agentteams-worker-devflow-lead`. The reconciler derives this mapping +unambiguously from Team status, the Pod worker label, and Pod metadata, then +installs the exact binding at `/etc/devflow/teamharness/runtime-binding.json`. +The guard never assumes those two names are equal. + +Projected ServiceAccount token paths need the same canonical-path discipline. +On the live cluster, `/var/run` resolved to `/run`; comparing a canonical token +child with an uncanonicalized configured parent caused a false rejection. The +guard now resolves both parent and child before enforcing containment. The +focused regression passed 73 tests with 2 skipped, and the immutable overlay +then reconciled successfully on all six roles. This handles a filesystem alias +without broadening the permitted token parent. + +For a direct installation, provide that reconciler-produced binding explicitly: + +```bash +python scripts/teamharness_openclaw.py install \ + --plugin-dir /opt/AgentTeams-src/plugins/teamharness \ + --workspace /root/hiclaw-fs/agents/devflow-worker \ + --role worker \ + --runtime-config /root/hiclaw-fs/agents/devflow-worker/runtime/runtime.yaml \ + --runtime-binding /run/devflow-policy/runtime-binding.json \ + --replace + +python scripts/teamharness_openclaw.py verify \ + --workspace /root/hiclaw-fs/agents/devflow-worker \ + --role worker +``` + +For the fixed six-role `devflow-swe` Team, the host-side reconciler performs +that post-rebuild operation consistently across all Pods: + +```bash +python scripts/reconcile_teamharness_openclaw.py \ + --agentteams-repo /opt/AgentTeams-src \ + --approval-public-key /operator-policy/approval-ed25519.pub \ + --approval-domain +``` + +It requires the AgentTeams checkout at commit +`78d0ceda336befa6e62bf89fc1a6b08b965e128d`, a clean tracked +`plugins/teamharness` tree, and the four pinned critical hashes above. Before +copying anything, it requires exactly one active, Running and Ready OpenClaw +Pod for each of the Leader and five Worker roles. It preflights all six +workspaces, stages only tracked upstream plugin files plus the two DevFlow +overlay files, verifies every staged hash, installs Leader as `leader` and all +others as `worker`, passes the public key and public deployment domain only to +Leader installation, and requires the adapter's final verification in every +Pod. The Ed25519 private +key must remain with the external human approver and must never be copied to +the repository, package, host staging tree, or Pod. Any missing, duplicate, +terminating replacement without a Ready successor, +unready, unknown, or drifted role/source fails the run. -The bundled MCP URL is the upstream local-install gateway endpoint. Replace it -when the AgentTeams gateway uses another hostname, port, or HTTPS origin. +The reconciler reads only Team/Pod metadata and status and uses `pods/exec` to +stage and run the adapter. It never reads Secrets, prints runtime +configuration, creates Kubernetes resources, or applies/patches RBAC. Its +ServiceAccount or operator identity therefore needs only the already approved +Team/Pod `get` and target-Pod `exec` permissions; do not grant broader rights +for this workflow. + +Do not treat successful overlay verification as a replacement for the +Kubernetes, Higress, NetworkPolicy, or human-approval boundaries. + +## Role-scoped Skill reconciliation after a Pod rebuild + +The AgentTeams MinIO workspace is persistent. A replacement Pod can therefore +restore DevFlow Skills that were intentionally omitted from its role package. +Run the fail-closed reconciler after every Team creation, package upgrade, or +Pod replacement, first in read-only check mode: + +```bash +python scripts/reconcile_agentteams_role_skills.py +``` + +The only accepted policy is the fixed six-role, seven-Skill map: Lead has no +DevFlow Skill; Triage owns `issue-classifier`; Locator owns +`code-root-cause` and `github-evidence`; Coder owns `patch-generator`; Tester +owns `test-runner`; and Reviewer owns `pr-reviewer` and +`experience-distiller`. The command requires exactly one Running and Ready Pod +for every role and validates the role identity, `HOME`, current directory, +workspace path, runtime trust chain, local tree, and exact MinIO object keys. +The object-store trust root is also fixed: the authoritative prefix must be +exactly `agentteams/agentteams-storage`, the endpoint must be the in-cluster +AgentTeams MinIO service, and `/usr/local/bin/mc.bin` must match the recorded +release version and SHA-256. Every helper invocation creates a private `0700` +configuration directory, initializes and reads back only the `agentteams` +alias, and never consults the worker's writable `$HOME/.mc` configuration. +Before contacting Kubernetes it validates all six `dist/*-v1.3.0.zip` files, +their sidecars, canonical ZIP and internal manifests, exact per-file hashes, +the current release source reconstruction, and six version-pinned outer ZIP +hashes. Changing source while retaining version `1.3.0` therefore fails; a +different release requires a version and pinned-digest update. +Its JSON result exposes only the fixed known-Skill sets, counts, and +`needsApply`; it does not return Skill contents, MinIO configuration, or +credentials to the host. `devflowPolicyVerified=true` means only that the +fixed seven-Skill DevFlow policy agrees across the controller archive cache, +controller persistent Skill cache, Worker-local trees, and MinIO. +`completeRoleSkillBoundaryVerified=false` remains explicit because built-in, +platform, and unknown Skills are outside that complete-boundary claim and are +never deletion targets. + +After reviewing all six role results, apply the fixed plan with: + +```bash +python scripts/reconcile_agentteams_role_skills.py --apply +``` + +Apply mode repeats the full six-Pod check and requires identical snapshot +digests before changing any role. It then runs a non-production temporary +filesystem preparation on all six Pods and requires working directory `fsync`, +Linux `RENAME_EXCHANGE`, and `RENAME_NOREPLACE` (including collision behavior) +with unchanged Skill snapshots before the first MinIO or local mutation. For +each drifted Pod it deletes only a +disallowed member of the known seven-Skill set, first at the exact authoritative +`/agents//skills//` component-bounded prefix and +then at the exact local `skills/` directory. Missing, partial, stale, +extra-file, or mode-drifted allowed trees are not trusted or preserved: the +host streams only that role's pinned archive over Pod stdin, the Pod verifies +its outer hash, manifest self-hash, paths, sizes, and file hashes before any +mutation. MinIO replacement uses staged and backup trees plus a phase manifest +and readback so an interrupted run can recover or refuse inconsistent state; +this is crash recovery, not native atomic replacement of an S3 object tree. +The local tree is swapped with Linux `renameat2(RENAME_EXCHANGE)`, and the +displaced tree must retain its preflight identity before it can be deleted. +Complete allowed, built-in, and unknown Skills remain unchanged. A final +content and manifest readback must show the exact policy on all six Pods. The +command does not create Kubernetes resources, patch RBAC, or read Kubernetes +Secrets. All `kubectl` and MinIO subprocesses have fixed deadlines; captured +output and object reads are bounded before parsing. Sensitive MinIO values are +kept out of child-process arguments, and the remote helper body and archive are +sent through bounded stdin rather than command-line arguments. + +A remote deployment cannot contain only this script and `dist`. The minimal +release overlay is: + +- `scripts/reconcile_agentteams_role_skills.py`, + `scripts/reconcile_agentteams_packages.py`, + `scripts/build_agentteams_package.py`, + `scripts/reconcile_agentteams_mcporter_policy.py`, and + `scripts/reconcile_teamharness_openclaw.py`; +- `agentteams/worker-package/`; +- all seven directories under `skills/` named by the fixed policy; and +- all six `dist/devflow-*-v1.3.0.zip` files and their `.sha256` sidecars. + +Keep their repository-relative layout. Package loading reconstructs the +release from the source root derived from the package reconciler's own path; +copying only the archives would intentionally fail source attestation. + +This is a deterministic repair and integrity check, not a cross-Pod atomic +transaction or a sandbox. A Pod failure can leave a multi-Pod run to be +resumed or rerun. The staged/backup MinIO protocol is crash-recoverable, but +S3 still offers no atomic tree swap and concurrent privileged writers remain +outside the claim. A privileged process can also race a local path after its +last metadata check. Mounts at or below `skills/` are rejected, but workers +still remain UID 0 with workspace credentials. A hostile root process can +race or replace the otherwise hash-pinned client after attestation or tamper +with runtime state; this is not a hostile-root integrity claim. OS-level +isolation still requires non-root containers, a read-only pinned client and +policy mount, disabled mount/ptrace capabilities, and a separately role-scoped +credential broker. + +Live follow-up on 2026-07-28 closed the previously recorded reconciliation +failure. The immutable `final4.4` apply converged the fixed seven-Skill DevFlow +policy across all four runtime surfaces: controller archive cache, controller +persistent Skill cache, Worker-local trees, and MinIO. An independent +read-only check then returned `devflowPolicyVerified=true` with no changed +roles. After Locator replacement, it retained exactly `code-root-cause` and +`github-evidence`; all six Pods were Ready. The deliberately narrower result +also returned `completeRoleSkillBoundaryVerified=false`: this verifies the +named seven DevFlow Skills, not a complete boundary over built-in, platform, +or unknown Skills, and not strong OS isolation. + +That distinction was confirmed by a real Locator task: the package held the +current 12,925-byte GitHub authorizer, while persistent storage restored an +older 1,892-byte copy without the required envelope/capability CLI. Locator +returned `SKILL_RUNTIME_VERSION_MISMATCH` as `FAILED`; an identical retry was +idempotent and an altered retry was rejected as `submit_result_conflict`. +This remains valid failure/retry evidence, distinct from the later successful +task. + +### 2026-07-28 operator-driven success sequence + +The fresh success path required six attempts. Run 1 returned no result. Run 2 +failed closed when the real ACK field did not match the driver's precondition. +Run 3 found a misconfigured role-scoped shared path.

It controls workflow state and escalation but cannot perform a +worker's domain work. Publishing or merging a candidate is also deliberately +outside the current autonomous closure boundary. The portable core can place +PR creation/review behind explicit grants, but the current AgentTeams Reviewer +has no GitHub write capability; repository branch protection and a human or +external release process retain merge authority. + +## Runtime Skill policy boundary + +The live `final4.4` apply and a separate read-only check converged the fixed +seven-Skill DevFlow policy across four surfaces: controller archive cache, +controller persistent Skill cache, Worker-local trees, and MinIO. A Locator +replacement retained exactly `code-root-cause` and `github-evidence`, and all +six Pods remained Ready. This evidence is deliberately scoped: +`devflowPolicyVerified=true` and +`completeRoleSkillBoundaryVerified=false`. It does not assert a complete +boundary over built-in, platform, or unknown Skills, and it does not imply a +hostile-root or OS sandbox. + +MinIO updates use a staged tree, backup tree, phase manifest, and byte readback +so an interrupted operation can recover or fail closed. This is +crash-recoverable application-level transaction handling, not atomic +replacement of an S3 object tree and not a cross-Pod atomic transaction. + +## Enforced hand-off contract + +Each domain transition is a `HandoffEnvelope` containing the producer, +consumer, Skill, status, artifact type, inline payload, idempotency key, and +SHA-256 digest. Before an Agent executes, the runtime verifies: + +1. the named consumer is the executing Agent; +2. the named Skill is owned by that Agent; +3. status is `READY` or `RETRY`; +4. the payload digest is intact; +5. the artifact is inline and typed at the receiving stage. + +In the portable Python runtime, failed tests return through TeamLeader +mediation. The result is sanitized first; TeamLeader verifies one digest over +the complete sanitized result and forwards only bounded +`TestFailureEvidence`, never the raw result or a raw-result digest. Local tests +exercise the automatic Coder-to-Tester-to-Leader-to-Coder loop. A failed +review is deliberately different: Reviewer addresses a typed decision to +TeamLeader, which validates it and fails closed for human re-planning until a +formal retry contract binds review feedback to the exact candidate. No bare +review dictionary is executable. + +Generic execution failures carry a canonical route claim +`(handoff_sha256, execution_attempt)`. One TeamLeader instance claims that +route before its first asynchronous yield, audits every distinct failure +event, and emits at most one retry route. Coder failures instead stay in the +generation domain. Every canonical Coder route leases exactly one +`model_call_attempt`; TeamLeader issues ordinals 1 through 3 sequentially and +never a fourth. Candidate-validation failures and semantic test retries consume +the same issue-global budget, so their worst case is three model calls rather +than two stacked three-attempt loops. `PatchCandidate` 1.2 echoes the ordinal +and binds it to the exact retained source route. + +These claims remain process-local memory. The local scheduler asks TeamLeader +to claim an exact route before dispatch, so duplicate delivery cannot repeat a +model-call lease even if the Worker instance changes inside that Leader +runtime; BaseAgent also caches direct successful redelivery. A deterministic +idempotency key is correlation material, not by itself a durable exactly-once +guarantee. The repository tests do not claim state survival across process +restart, multiple TeamLeader replicas, or broker redelivery after Leader state +loss. + +A T4/T5 review emits a blocked envelope for `HumanReviewer`; it is not +silently converted into success. Repository code and tests cover the gate and +approval validation. Live evidence currently covers pause and rejection of an +unapproved resume, but not a human signature followed by successful resume. + +Coder accepts `patch-generator` envelopes only from TeamLeader, requires exact +initial/retry input fields, and binds a retry to the previous candidate. Before +calling the model it redacts supported credential shapes from issue and located +context. Before emitting a candidate it enforces repository-relative paths, +the Locator-derived file allowlist, change-type/diff-header consistency, +Python syntax for Python outputs, dangerous-pattern denial, and a whole-artifact +secret scan. + +The guarded TeamHarness path independently binds collaboration state. Project +risk is read from the root-owned ledger, source is read from persistent project +state, and every relevant action cross-checks those authorities. Task-room +creation and readback require Matrix private/invite-only state and the exact +actual member set. Returned `invite`/`members` fields are labeled as the +non-creator requested-worker projection; the full set is represented by its +verified count and digest. Idempotent retry and conflict evidence bind both +`taskId` and submission digests. The final operator-driven T2 run exercised +these bindings; it remains separate from the earlier honest failed task. + +### Guarded TeamHarness surface + +| Runtime role | Direct TeamHarness tools | +|---|---| +| Leader | `health`, `message`, `roomflow`, `filesync`, `artifact`, `projectflow`, `taskflow` | +| Worker or remote-member | `health`, `taskflow` | +| Manager | `health`, `message` | + +Worker and remote-member runtimes cannot directly invoke `artifact` or +`filesync`. Their boundary ends at an idempotent `taskflow` submission; Leader +owns the final bounded synchronization. + +The filesync schema accepts only required `action`/`path` plus optional +`dryRun`. Caller exclusions and unknown fields fail closed. Canonical requested +paths and recursive child segments use the same allowlist, `global-shared` is +read-only, and the resolved real workspace must exactly match the attested +runtime identity. Push rejects symlinks, hardlinks, empty directories, more +than 32 files, more than 10,000 entries, or more than 64 MiB. Its local tree +fingerprint includes each entry's size and nanosecond mtime plus each regular +file's SHA-256. A non-dry-run success requires every expected object to return +a separately path/workspace-bound `stat exists=true`, with an unchanged local +tree before and after. An existing pull target must show a provable change. + +### 2026-07-28 bounded live follow-up + +The operator retained six attempts as separate records: Run 1 returned no +result; Run 2 exposed a mismatch between the real ACK field and the driver's +precondition; Run 3 found a misconfigured role-scoped shared path; Run 4 +completed the core project path but failed filesync binding; Run 5 reached an +internal guarded push result of two verified objects out of two but the outer +minimal executor had not admitted the independent `stat` operation; Run 6 used +the final pins and completed the bounded T2 path. No actual project, room, +capability, endpoint, credential, or raw repository content is retained here. + +The final record has project state `completed`, requester `pending=false`, and +`validatorPassed`, `firstSubmit`, `idempotentRetry`, `conflictRetry`, +`postConflictReadbackBound`, and `leaderCheckEffective` all `true`; the altered +retry was rejected and Leader read back `effective=true`. Push returned +`expectedObjectCount=2` and +`verifiedObjectCount=2`; independent stats for `meta.json` and `plan.md` each +returned `exists=true`. All six Pods were Ready. The role-policy check found +zero drift and retained `devflowPolicyVerified=true` with +`completeRoleSkillBoundaryVerified=false`. + +The deployed TeamHarness `final4` and driver `final7` tree SHA-256 values were, +respectively, +`263681c7526daa09940bc3b2c754957f6cd7341ed0f38bfa3f78af5a06f12d40` +and +`10aa2f3bc09d90970229c997dab595de52557b84b1d6719cf4191b968e129781`. +The Leader TeamHarness canonical schema pin was 28,909 bytes at +`985fbb53710bc62f34e0194783a68852e4a7400bea794b6600023f96bf730eea`. +Locator pins remained 1,742 bytes at +`2588f5c5d201588468e86c93899f22ff913b98c7c6784173b23640b1718ab887` +for the read-only GitHub MCP schema and 4,203 bytes at +`a4243ba99239622210efd749ac06e30d3d7d1673c4cbf07db80720ed5859b69a` +for TeamHarness. + +Remote stat proves existence at a bound object path, not a digest of the remote +bytes. The in-process pre/post checks cannot eliminate a same-UID +swap-and-restore race, and a failure detected after an upstream call does not +prove that no external write occurred. Consequently +`strongBoundaryEnforceable=false` remains the correct system result.

It rejects +unknown tools, wrong Agent/Skill pairs, protected-branch writes, repository +path escapes, secret-shaped arguments, malformed patches, and dangerous calls +without matching approval evidence. Its local approval authority signs outside +the Agent boundary with a server-held HMAC key and binds the action, canonical +target, arguments digest, approver, and timestamp. Invalid, expired, modified, +or unverifiable evidence fails closed in those tests; this is not evidence that +the live AgentTeams T4 approval/resume has occurred. Calls to a DevFlow-owned +MCP server also carry an HMAC-signed context, so a local caller cannot forge +its Agent or Skill identity; the server rejects unsigned or modified context. +Audit entries contain identity, trace and argument digests, but never raw +credentials or raw arguments. + +The hardened AgentTeams success driver does not pass sensitive MCP inputs on a +child command line. TeamHarness uses direct pinned stdio JSON-RPC and Locator +uses Streamable HTTP directly; sensitive fields stay in process memory and +protocol bodies/headers. Before execution the driver attests the exact +role×server configuration and schema, enforces a remote deadline shorter than +the host deadline, bounds captured diagnostics, and performs cleanup. The +operator-driven T2 run above completed through this path; it is not a claim of +an autonomous or general six-stage success. + +For `cicd:run_tests`, the repository implementation makes the server own the +test command as an argument vector. Local integration tests show that it +accepts a typed Patch, copies the repository to a disposable directory, checks +stale original content, applies create/modify/delete operations there, and +runs with `shell=False` and a bounded timeout. Those tests verify that the +canonical repository is not mutated; a live AgentTeams CI/CD run has not yet +been retained as server evidence. + +## Sources of truth and drift prevention + +- `config/agents.yaml` declares identities, capabilities, watched events, and + human-readable boundaries. +- `skills/*/references/contract.yaml` declares each Skill's exact MCP tools. +- `config/mcp_servers.yaml` declares the corresponding Agent + Skill grants. +- `config/security.yaml` declares credential capabilities, branch protection, + approval, and rollback policy. +- `src/devflow/agents/base.py` enforces hand-offs and constructs trusted MCP + call context. +- `src/devflow/mcp/policy.py` enforces grants and emits audit evidence. +- `src/devflow/mcp/cicd.py` enforces isolated, server-owned test execution. + +`scripts/evaluate_skills.py` fails when configured Agent ownership, Skill +ownership, declared tools, and MCP grants are not an exact match.

The audited live Console serves SPA HTML from both paths. The default is +therefore refusal. Source-contract fallback is available only when the operator +explicitly supplies the exact audited image digest: + +```text +sha256:90ccdbb078375aad42f874feddba9d964eca34f192ee8dbab7d9a22079b580a4 +``` + +The script compares the complete value and rejects every other digest. This is +not automatic image discovery: the operator must first verify the running Pod +image. The pin permits fallback only when both documentation endpoints are +non-JSON or unavailable. If either endpoint returns JSON with a changed schema, +the mismatch remains blocking and the pin cannot bypass it. + +The audited deployment returns HTTP 201 as well as 200 from session login and +returns HTTP 201 when creating a DNS service source. Those codes are accepted +only for those exact operations; unrelated reads and writes keep their narrow +response contracts. A missing MCP server is unusually reported as HTTP 502. +Only the exact Console wrapper with `success=false`, `data=null`, and +a message containing +`NotFoundException: can't found the bound route by name` is treated as absent, +and only for `GET /v1/mcpServer/devflow-github-readonly`. Every other 502 is an +error. Missing service sources continue to require the normal HTTP 404. + +The request also carries `mcpServerName` equal to `name`. AgentTeams' pinned +Console backend requires this route-binding compatibility field even though +the generated `McpServer` schema in the bundled API reference omits it. The +Console also omits this compatibility-only field from later GET responses, so +response validation binds identity through `name`, the dedicated route, exact +domain/service surface, and the Locator-only consumer list. +For that consumer list, the pinned Console returns the deterministic internal +route name `mcp-server-devflow-github-readonly.internal`; requests still use +the logical `devflow-github-readonly` name. No other returned route name is +accepted. + +Unknown wrappers, malformed configuration, an existing name collision, or an +incompatible `devflow-github-content-broker` service source also stops the run. + +The script has no third-party runtime dependency. A Console v2.2.1 defect makes +the concrete spelling security-relevant: `OpenApiSaveStrategy` enables the +route-scoped plugin only when `rawConfigurations` literally contains +`tools:`. Strict JSON is valid YAML but lacks that substring, so the Console +writes `configDisable: true` and traffic bypasses MCP tool handling. PUT now +emits a deterministic, fully closed 36-line YAML document containing the bare +`tools:` key. Every string is JSON-style double-quoted to prevent scalar or +indentation injection. The tree contains no PAT, `Authorization` header, or +server credential configuration. + +The pinned Console normalizes that YAML on GET into the same 36-line block +document with `server`, then `tools`; the single tool starts with the +indentless `- args:` form. DevFlow accepts that observed form without +installing PyYAML, but it does not expose a general YAML parser. Historical +strict-JSON GET values remain readable and are checked for semantic equality, +but apply deliberately re-PUTs them as the enableable YAML spelling. + +The GET validator recognizes exactly two encodings of the same closed tree: + +- strict JSON, with duplicate object names rejected; +- the exact Console v2.2.1 36-line YAML spelling, including key order, + indentation, six ordered required string arguments, the managed tool name + and description, the single capability header, the fixed content-broker URL, + and `GET`. + +The Console emits every string as a canonical JSON-style double-quoted YAML +scalar. Any injected server `config`, access token, `Authorization` header, or +additional argument/header is rejected. +A second tool, a write method, a body, duplicate or unknown fields, changed +descriptions or headers, anchors, aliases, tags, merge keys, unquoted or +non-canonical scalars, blank suffixes, and any trailing document content all +fail closed. +JSON GET responses remain supported, but must represent the same exact values; +JSON is not a looser compatibility path. CI proves import, help, deterministic +YAML rendering, and normalized-YAML validation under `python -S`. + +Console equality alone is not success. Check and apply also perform a read-only +`kubectl get wasmplugins.extensions.higress.io/mcp-server.internal -o json` and +require the effective CR to have `defaultConfigDisable: true`, +`failStrategy: FAIL_CLOSE`, an exact `oci://...@sha256:<64-lowerhex>` URL supplied +through `--pinned-wasm-plugin-url`, and exactly one match rule for +`mcp-server-devflow-github-readonly.internal`. That rule must target only that +Ingress, have `configDisable: false`, and contain the exact one-tool +configuration above. Apply first asks Console to regenerate the rule with a +re-PUT and then merge-patches only `spec.failStrategy` and `spec.url`. A final +reread is mandatory. Console or controller reconciliation can later overwrite +those fields, so production must run this check continuously; a later +`FAIL_OPEN` state is drift, never compliance. + +## Credential boundary + +Higress never stores or forwards the GitHub token. The content broker alone +reads `DEVFLOW_GITHUB_TOKEN` from the pre-created +`Secret/devflow-github-scope-broker` key `github-token`; it rejects any client +`Authorization` header and constructs the upstream header from its in-memory +server credential. The issuer Deployment does not mount that key. Both broker +processes also require the non-secret, canonical repository ceiling +`DEVFLOW_GITHUB_ALLOWED_REPOSITORIES` (production: `YZYY95K/test`) and enforce +it independently. + +The Console administrator password is accepted through +`HIGRESS_ADMIN_PASSWORD` or `--console-password-secret NAME:KEY`. Secret values +are read through `kubectl get secret -o json`, decoded only in process memory, +and never passed as command-line arguments.

Command output, request bodies, response bodies, tokens, +and cookies are never logged. + +The issuer accepts the Leader's projected ServiceAccount JWT and submits it to +Kubernetes TokenReview with audience `agentteams-controller`.

Extra or legacy credentials are blocking +and must be explicitly rotated at the AgentTeams identity source; this script +does not guess replacement credential material. It creates the broker DNS +source only when absent and never rewrites an incompatible source. It leaves +the server untouched only when the Console representation is enableable and +semantically exact **and** the runtime rule is enabled, fail-closed, and pinned. +Historical JSON, disabled runtime state, or configuration drift causes a +Console re-PUT, but only for a resource carrying DevFlow's managed description. + +The Console v1 MCP consumer API has no resource version or optimistic locking. +The script therefore uses a dedicated server, removes every non-Locator +binding, adds Locator when missing, and performs mandatory final re-reads. Any +concurrent drift or unexpected response fails the run instead of being +reported as success. + +Successful default-mode output is named `control-plane-compliant`, not +end-to-end. End-to-end evidence additionally requires an external MCP +initialize/tools-list exchange, one authorized immutable-revision read, an +incorrect-scope denial, and a TokenReview identity denial. + +## Durable MCP session Redis + +Higress MCP session storage is a separate infrastructure boundary from the +GitHub tool credential. The official Higress MCP documentation defines Redis +`username` and `password` as optional. DevFlow therefore does **not** generate, +store, print, or rotate a Redis password. It uses empty values and limits reachability +at the Kubernetes network boundary instead: + +- a private `ClusterIP` Service on TCP 6379; +- ingress only from same-namespace Pods labelled `app=higress-gateway`; +- no Redis Pod egress; +- no ServiceAccount token mount; +- non-root execution, dropped Linux capabilities, and the runtime-default + seccomp profile; +- a digest-pinned official Higress `redis-stack-server:7.4.0-v3` amd64 image; +- AOF persistence on a `local-path` `ReadWriteOnce` volume. + +Source: [Higress MCP Server Docker quick start](https://higress.io/docs/ai/mcp-quick-start_docker/). + +Apply the storage asset and wait for its single replica to become ready before +changing the shared Higress configuration: + +```bash +kubectl apply -f agentteams/higress-redis.yaml +kubectl --namespace agentteams-system rollout status \ + deployment/devflow-higress-redis +python scripts/configure_higress_mcp_redis.py --apply +python scripts/configure_higress_mcp_redis.py --check +``` + +Check mode is the default and never writes; run it before apply when an +expected non-zero drift result is useful for change-control evidence. Both +modes first require the exact +private Service contract and exactly one ready EndpointSlice. Apply mode then +accepts only an unambiguous block-style `mcpServer.redis` structure, refuses to +overwrite any non-empty Redis credential, and replaces the ConfigMap with its +existing Kubernetes `resourceVersion`. The only exception is the complete, +fixed AgentTeams placeholder tuple (`your.redis.host:6379`, `your_username`, +`your_password`, DB 0); a partially changed tuple remains blocking. A +concurrent write therefore fails +instead of being lost. A final re-read must show both a new resource version +and the canonical state. Kubernetes command output and ConfigMap contents are +never printed. + +The generated address is fixed to +`devflow-higress-redis.agentteams-system.svc.cluster.local:6379`, with database +`0` and empty `username`/`password`. Do not expose the Service, add broader +NetworkPolicy peers, or copy Redis values into Agent prompts. Confirm that the +cluster's CNI actually enforces Kubernetes NetworkPolicy before deployment. + +This one-replica `local-path` setup is intentionally suitable for the current +single-node AgentTeams environment, not for high availability. A production +multi-node cluster should replace it with an HA Redis service and encrypted, +authenticated transport under a separately audited configuration contract. diff --git a/docs/INFRASTRUCTURE.md b/docs/INFRASTRUCTURE.md new file mode 100644 index 0000000..70f61bf --- /dev/null +++ b/docs/INFRASTRUCTURE.md @@ -0,0 +1,72 @@ +# Executable infrastructure and trust boundaries + +This document is an evidence map for the infrastructure that is executed by +DevFlow.

Before +each write it canonicalizes the full configuration with only `allowBots` and +`streaming` removed and requires byte equality, proving no other field changed. +It also uses optimistic concurrency checks for both object storage and the live +file. + +This is a beta-version compatibility layer, not a permanent fork. Re-test and +remove individual patches as upstream releases close the corresponding gaps. diff --git a/docs/evidence/AGENTTEAMS_LIVE_20260727.md b/docs/evidence/AGENTTEAMS_LIVE_20260727.md new file mode 100644 index 0000000..8d74c88 --- /dev/null +++ b/docs/evidence/AGENTTEAMS_LIVE_20260727.md @@ -0,0 +1,390 @@ +# AgentTeams live evidence — 2026-07-27 (updated 2026-07-28) + +This record distinguishes observed runtime evidence from local tests and from +remaining operational limitations.

Triage completed at 09:57:46, mentioned Leader in one final base +event, and automatically started the Leader at 09:57:57. Leader completed at +09:58:29. This was a model-backed bot-to-bot path, not an injected transcript. + +## Guarded TeamHarness boundary + +The upstream TeamHarness stdio MCP was installed behind DevFlow's process-role +guard. Observed tool surfaces were: + +- Leader: `health`, `message`, `roomflow`, `filesync`, `artifact`, + `projectflow`, `taskflow`. +- Worker and remote-member: `health`, `taskflow`. Neither role can call + `artifact` or `filesync` directly. +- Manager: `health`, `message`. + +A Worker attempted `taskflow.delegate_task` while supplying `role=leader`. +The guard replaced the untrusted argument with the process role and returned a +`forbidden_tool` result. Runtime mcporter configuration contained only +non-secret paths and role facts; credentials remained inherited from the +AgentTeams process. + +The first live GitHub delegation after this installation also exercised a +projected ServiceAccount-token path. Kubernetes exposed the token beneath +`/var/run`, while canonical path resolution mapped that parent to `/run`. +The guard originally canonicalized the child but compared it with the +uncanonicalized parent, so it rejected a legitimate projected-token alias +before any GitHub request was attempted. The fix canonicalizes both the +configured parent and child before containment checking. Its focused suite +passed 73 tests with 2 skipped, the immutable overlay was redeployed, and all +six roles then passed TeamHarness reconciliation. This is a path-validation +compatibility fix; it does not weaken the exact-parent containment rule. + +This is a collaboration misuse guard, not a hostile-tenant sandbox. The hard +boundaries remain Kubernetes identity/RBAC, Higress Consumers, NetworkPolicy, +and scoped credentials. The current OpenClaw TeamHarness overlay also requires +the documented post-reconcile installation step after a Team is recreated; +automatic recreation recovery is not claimed. + +### 2026-07-28 guard implementation/test follow-up + +The current TeamHarness guard and focused tests now derive each collaboration +claim from its designated authority instead of trusting request fields: + +- project risk is bound to the root-owned ledger; +- project source is read back from persistent project state; +- Matrix task rooms must be private and invite-only, with the exact actual + member set verified from Matrix state; +- returned `invite`/`members` fields are explicitly labeled as the + non-creator requested-worker projection, while the full set is represented + by its verified count and digest; and +- idempotent retry and conflict results bind `taskId` and submission digests. + +The guarded filesync surface now exposes only `action`, `path`, and optional +`dryRun`; `action` and `path` are required and extra properties fail closed. +Any caller-supplied `exclude`, including an empty list, is rejected. Requested +paths and every recursive source segment use the same conservative allowlist, +`global-shared` remains read-only, and the local root must be the resolved real +directory exactly bound to the runtime identity. A directory push must contain +between one and 32 ordinary files; the guarded tree is capped at 10,000 entries +and 64 MiB and rejects symlinks and hardlinks. Its pre/post fingerprint includes +size, nanosecond mtime, and each regular file's SHA-256. A non-dry-run push is +reported as successful only after every expected object receives a separately +bound `stat` response with `exists=true` and the local tree remains unchanged. +An existing pull target must show a provable post-operation change. + +These controls were first implementation/test facts. The later operator-driven +run below exercised the final push/readback path without changing the narrower +scope of the earlier honest failure. + +## Real project lifecycle + +An earlier live project used one dedicated task room and two dependent nodes: + +1. T1 — Triage classification. +2. T2 — independent Reviewer verification of T1 evidence. + +Observed lifecycle, China Standard Time (UTC+8): + +- Reviewer joined the task room at 18:13:07. +- Because the earlier assignment predated room membership, Leader used + TeamHarness to resend one complete, bounded T2 instruction at 18:22:16. +- Reviewer started at 18:22:29 and acknowledged T2 at 18:23:20.755. +- Reviewer submitted `SUCCESS` at 18:24:25.233; TeamHarness returned success + and published the result at 18:24:25.895. +- The first completion notification met `Matrix sync entered STOPPED during + startup`; the channel automatically retried successfully at 18:24:50.068. +- Leader accepted the result at 18:25:10.676; the node became complete at + 18:25:11.270. +- Leader completed the project at 18:25:31.633; TeamHarness confirmed + `completed` at 18:25:32.205. +- The completion report was sent at 18:25:44.464 and marked sent at + 18:25:52.165. A final filesync push repaired a detected local/object-storage + lag without changing project semantics. + +Final authoritative state: + +- Project: `completed`; requester report `pending=false`. +- T1 and T2 project nodes: `completed`. +- T1 and T2 Worker task results: `submitted`, `SUCCESS`, `effective=true`, + `validationErrors=[]` (the separate Worker-task and accepted-project-node + states are expected TeamHarness semantics). +- Reviewer GitHub, `git`, and `gh` tool/command calls: zero. +- T1 artifact SHA-256: `b3d09cfb2faa5361...e71046b`. +- T2 artifact SHA-256: `43ba42a2e0f3263...b908741d`. +- Project result SHA-256: `022ecb32533ddf8...21da8d4`. +- Project metadata SHA-256: `624bea9462a3f914...cf8f97a`. + +## T4 pause and approval boundary + +A separate live T4 project was created and then paused. The authoritative +project state reported `paused`. Attempting to resume it without an external +approval produced the stable fail-closed result: + +```text +approval_denied:approval must contain exactly evidence and signature +``` + +The Leader approval ledger was mode `0600`, bound to that project and `T4` +risk tier, and recorded no used nonces. Only the public verification key was +present in the Pods; no human approval signature was generated or copied into +the runtime. Therefore this evidence proves pause plus denial of an +unapproved resume. It does **not** prove a signed human approval or a +successful approved resume; both remain pending. + +## Higress MCP session storage + +The AgentTeams beta configuration contained only Redis placeholders, which +blocked real OpenAPI-to-MCP creation. DevFlow deployed the official Higress +Redis Stack image pinned to the audited amd64 digest, with a persistent 2 GiB +`local-path` volume, AOF (`everysec`), health probes requiring `PONG`, no +ServiceAccount token, non-root execution, dropped capabilities, and a private +ClusterIP Service. + +Observed state after deployment: + +- Ready: true; restarts: 0. +- PVC: Bound, 2 GiB, `local-path`. +- AOF enabled; last write status `ok`. +- Existing Higress gateway Pod could connect to TCP 6379. +- A DevFlow Worker Pod could not connect, demonstrating the intended + gateway-only NetworkPolicy path in this cluster. +- The Redis configurator applied the canonical address with empty optional + username/password and a second check reported `compliant`. + +## Scope-bound GitHub MCP + +The GitHub read path was exercised through the deployed Broker and Higress MCP +route after both runtime artifacts were pinned: + +- Broker image: + `devflow/github-scope-broker@sha256:af42d610e635b5a186717e7bf8b42bb1d1a602bbacb3f874769e4ade7d788712`. +- Higress MCP Wasm plugin: + `oci://higress-registry.cn-hangzhou.cr.aliyuncs.com/plugins/mcp-server@sha256:ee81701617d6fe5ceaab1d094a23a82a0a1ee7307918ae1031022be62fb5e4cd`. +- The live Wasm resource used `FAIL_CLOSE`. + +The positive read used exactly this non-secret scope: + +- repository: `YZYY95K/test`; +- revision: `cc6a79d6b633be640a78eadf081469d0038f2dd5`; +- path: `README.md`. + +The response identified Git object +`46e21a78b325810240ef6699de10e9441091b351`. The decoded content SHA-256 was +`2ffb00a778946b5a4477174222f7a3b7a39ffe1d8074fd477e3cafb8f7bad9b8`, and the +receipt response digest recomputed to the same value carried by the receipt. +The capability, its signature, the upstream credential, and the Higress +Consumer credential are intentionally not recorded here. + +Three negative checks exercised different enforcement layers: + +1. Reusing the same capability for a path outside its exact scope returned + HTTP 403 from the Broker path. +2. Calling the Higress MCP route as Reviewer returned HTTP 403; only the + Locator Consumer is admitted to this read route. +3. A Locator Pod could not connect directly to the content Broker because the + NetworkPolicy admits the gateway data plane, not Worker Pods. The positive + read succeeded only through Higress. + +Together these observations verify exact scope binding, MCP Consumer identity, +fail-closed Wasm configuration, receipt digest integrity, and network-path +separation. They do not prove the six-stage software-repair workflow, a T4 +human approval, or a post-update role-package rollout. + +## Real GitHub task: honest failure and retry semantics + +After the projected-token fix, Leader delegated a real, digest-bound GitHub +evidence task to Locator. The canonical handoff identified the producer, +consumer, task, and `github-evidence` Skill; Locator received and acknowledged +it. A short-lived capability was present but was never printed or written into +this evidence record. + +The task then exposed a persistent-workspace version mismatch before the +GitHub tool call. The role package contained the current 12,925-byte +`authorize_tool.py`, but MinIO restored an older 1,892-byte runtime copy whose +CLI lacked the required `--envelope` and `--capability` arguments. The Worker +submitted `FAILED` with the stable summary +`SKILL_RUNTIME_VERSION_MISMATCH`. Repeating the identical submission returned +`idempotent=true`; retrying with a different result was rejected as +`submit_result_conflict`. Leader's task check reported +`resultStatus=FAILED`, `effective=true`, and no validation errors. +Here `effective=true` means the submitted result was structurally valid and +authoritative; it does not turn the failed task into a success. + +This run proves canonical handoff/ACK, version-drift detection, honest failure +return, idempotent replay, and conflicting-result rejection. It does not prove +a successful AgentTeams GitHub task or a six-stage repair. + +## 2026-07-28 fixed-policy convergence and restart evidence + +The immutable `final4.4` apply converged the fixed seven-Skill DevFlow policy +across four runtime surfaces: the controller archive cache, controller +persistent Skill cache, Worker-local trees, and MinIO. An independent +read-only check then reported `devflowPolicyVerified=true` with no changed +roles. Locator was replaced and retained exactly its two expected DevFlow +Skills, `code-root-cause` and `github-evidence`; all six Pods were Ready and +the replacement Worker's restart count remained zero. + +This result is deliberately narrower than a complete role boundary. The same +summary states `completeRoleSkillBoundaryVerified=false`: built-in, platform, +and unknown Skills are outside the fixed-seven comparison and are not deletion +targets. It also does not alter the OpenClaw result +`strongBoundaryEnforceable=false` or establish hostile-root/OS isolation. + +The current reconciler implements MinIO changes as a staged/backup protocol +with a phase manifest and readback, allowing interrupted operations to recover +or refuse tampered state. This is crash-recoverable transaction handling, not +an atomic S3 tree replacement or a cross-Pod atomic transaction. Sensitive +MinIO configuration is kept out of child-process arguments, and the bounded +remote helper payload/archive is delivered over stdin. These implementation +properties describe the hardened reconciler; the live convergence evidence +above is the independently verified fixed-policy result. + +## 2026-07-28 operator-driven T2 success follow-up + +Six operator-driven attempts were retained as distinct evidence rather than +collapsing partial progress into a success claim: + +| Attempt | Observed outcome | +|---|---| +| Run 1 | Returned no result; no task or project success was inferred. | +| Run 2 | Stopped because the real ACK response field did not match the driver's precondition. | +| Run 3 | Stopped on an incorrectly configured role-scoped shared-path binding. | +| Run 4 | Completed the core scoped task and project path, but failed final filesync role/workspace binding. | +| Run 5 | TeamHarness push internally verified both expected objects, but the outer minimal executor did not permit its independent `stat` calls. | +| Run 6 | Used the final pinned TeamHarness and driver trees and completed the full bounded T2 path. | + +Run 6 is the accepted fresh success record. It deliberately omits the actual +project, room, capability, infrastructure endpoint, credential, and repository +content. The verified non-secret facts are: + +- risk tier was T2; the project reached `completed` and the requester report + read back `pending=false`; +- proof fields `validatorPassed`, `firstSubmit`, `idempotentRetry`, + `conflictRetry`, `postConflictReadbackBound`, and `leaderCheckEffective` + were all independently `true`; the conflict proof denotes rejection of the + altered retry and the Leader check returned `effective=true`; +- filesync push returned `expectedObjectCount=2` and + `verifiedObjectCount=2`, after which independent bound `stat` calls for + `meta.json` and `plan.md` each returned `exists=true`; +- all six AgentTeams Pods were Ready; +- the independent role-policy check found zero changed roles and retained + `devflowPolicyVerified=true` together with the deliberately narrower + `completeRoleSkillBoundaryVerified=false`; +- the TeamHarness `final4` deployed-tree SHA-256 was + `263681c7526daa09940bc3b2c754957f6cd7341ed0f38bfa3f78af5a06f12d40`, + and the success-driver `final7` deployed-tree SHA-256 was + `10aa2f3bc09d90970229c997dab595de52557b84b1d6719cf4191b968e129781`; +- the Leader TeamHarness canonical schema was 28,909 bytes with SHA-256 + `985fbb53710bc62f34e0194783a68852e4a7400bea794b6600023f96bf730eea`; + the unchanged Locator pins remained 1,742 bytes with SHA-256 + `2588f5c5d201588468e86c93899f22ff913b98c7c6784173b23640b1718ab887` + for the read-only GitHub MCP schema and 4,203 bytes with SHA-256 + `a4243ba99239622210efd749ac06e30d3d7d1673c4cbf07db80720ed5859b69a` + for its TeamHarness schema. + +The two remote `stat` results prove object existence at the exact bound paths; +they are not remote byte-digest attestations. The in-process guard also cannot +eliminate a same-UID swap-and-restore race between checks, and a failure found +after an upstream write does not prove that no external write occurred. The +native OpenClaw result therefore remains +`strongBoundaryEnforceable=false`. This T2 evidence is not a six-stage software +repair, a signed T4 approval/resume, or a Tester-to-Coder failure/retry loop. + +## OpenClaw native tool-boundary audit + +The read-only audit ran against all six Ready role Pods and intentionally +returned non-zero with `verified=false` and +`strongBoundaryEnforceable=false`. It reported these six stable blockers: + +1. `ROOT_RUNTIME_SHARED_WITH_AGENT_TOOLS` +2. `FS_WORKSPACE_ONLY_HAS_NO_SENSITIVE_PATH_EXCLUSIONS` +3. `OPENCLAW_POLICY_IS_STORED_IN_AGENT_WORKSPACE` +4. `EXEC_APPROVAL_STATE_IS_STORED_IN_AGENT_WORKSPACE` +5. `MCP_CREDENTIAL_CONFIG_IS_STORED_IN_AGENT_WORKSPACE` +6. `MCP_REQUIRES_GENERAL_PURPOSE_EXEC` + +Observed facts behind the result were consistent across all six roles: +OpenClaw ran as UID 0, role workspaces were writable, and OpenClaw policy, +exec-approval state, and MCP client configuration were colocated with the +agent-visible workspace. Consequently DevFlow may claim logical/process-role, +Higress Consumer, NetworkPolicy, and capability boundaries, but must not call +the current OpenClaw layout a strong hostile-root or OS sandbox. + +## Submission artifact QA + +The current preliminary presentation artifacts are complete local candidates: + +- `DevFlow_GOAI_2026_初赛方案_20260727.pptx`: 51,885 bytes, SHA-256 + `ffc838971097db2d6909c901a6684f7324daaca51e060a4bd7596ef2be321e6f`. +- `DevFlow_GOAI_2026_初赛方案_20260727.pdf`: 1,242,343 bytes, SHA-256 + `c350edda5880b23ae93f2ff045a0833e492960f793b5df32f64aefac4378db07`. + +Both contain 12 pages.

RAG 离线模式是不是语义检索？ + +不是。`local-hash` 是确定性 feature hashing 降级模式，用于离线可用与测试； +生产语义质量必须使用已开通的 embedding provider。两者在报告中明确区分。 + +## 10. 为什么不直接用覆盖率证明系统可靠？ + +覆盖率只说明哪些代码被执行，不证明职责边界正确或现场闭环真实。2026-07-28 +当前 v1.3.0 候选工作树的完整结果是 846 passed、17 skipped、84.40% +（3,874/4,590），但尚未 +绑定最终 commit，提交前必须在冻结版本上复跑。最终证据还要同时包含行为评测、 +拒绝测试、真实服务器状态和人工门记录。 + +## 11. 三仓库 24 项是否等于完整补丁解决基准？ + +不等于。它测量真实源码条件下的路由、边界、安全与成本。完整 issue-resolution +必须在固定、可复现的仓库环境中应用补丁并运行项目测试。当前 24 项不得表述为 +“修复 24 个缺陷”，也不得写成“SWE-bench 24/24”。 + +## 12. AgentTeams 真实运行到底完成了什么？ + +新服务器已运行真实 AgentTeams：一个 Leader、五个 Worker，完成了机器人交接 +以及 Triage 到 Reviewer 的两节点项目生命周期，并观察到 Worker 冒充 Leader +被拒绝。固定七项 DevFlow Skill 策略随后在控制器两级缓存、Worker 本地树和 +MinIO 四个运行面完成收敛，Locator 替换后仍只保留两项预期 DevFlow Skill， +六个角色 Pod 为 6/6 Ready，独立检查为 0 drift。此后又完成一次 fresh、 +operator-driven 的 T2 GitHub 边界任务：项目 `completed`、requester report +`pending=false`，并具备 validator、首提、幂等、冲突拒绝、冲突后读回、 +Leader `effective` 与文件同步 2/2 证据。它仍不是六阶段软件修复；Tester 失败 +回传 Coder、T4 真人签名批准恢复、正式平台回执和正式录屏尚未完成。一次 T2 +成功也不能用作整体成功率。早期受限服务器的 Docker 阻塞记录仍保留，但不再 +代表当前环境。 + +## 13. Tester 或 Reviewer 与 Coder 冲突时听谁的？ + +设计与本地运行时均坚持证据优先：红测先返回 TeamLeader，只有完整摘要验证 +通过后才以结构化、脱敏且有界的失败证据重路由 Coder。Reviewer 拒绝同样先由 +TeamLeader 校验，但当前没有候选绑定的修复契约，因此 fail-closed 并要求人工 +重规划，不把裸审查意见直接执行为补丁。T4/T5 进入人工门，TeamLeader 不能覆盖 +这些硬门。Tester→Coder 的真实 AgentTeams 现场回路仍是待办。 + +## 14. 如何控制成本与无限重试？ + +契约和配置定义调用时间、token 与 attempt 上限；当前本地失败恢复测试进一步 +验证 generic execution retry 的 route-level claim，以及每个 canonical Coder +route 只授权一次模型调用。候选验证失败与 Tester 语义失败共享由 TeamLeader +顺序签发的 issue-global 1..3 预算，不会产生第四次调用，也不会再叠加通用执行 +重试。route claim 是进程内状态，不是 +跨重启或多副本 exactly-once。基准只在 provider 返回可用数据时记录 token 与 +p50/p95 时延；不能用配置中的 exponential backoff 字段冒充已观察到的运行行为。 + +## 15. 开源复用价值在哪里？ + +Agent 身份、Skill 包、typed contracts、MCP grants、评测清单和验证脚本都在 +Apache-2.0 仓库中，可替换模型、Git 提供商或 CI provider，而不改变信任模型。 + +## 16. 为什么说有七个 Skill，行为评测表却只有六个？ + +`github-evidence` 是后续新增的第七个 Skill，已有严格契约、独立验证器、静态 +质量门和篡改负例；2026-07-24 的 GLM-5.2 成对评测早于它，因此只覆盖六个 +Skill。我们不会把旧分数平移给新 Skill，新增行为评测完成后再更新材料。 + +## 17. HumanReviewer 为什么不算第七个 Agent？ + +它是系统外部的授权主体，不是自主执行 Worker。把真人审批者算成 Agent 会混淆 +责任与信任边界。参赛口径始终是六个自主 Agent，T4/T5 由外部 HumanReviewer +提供摘要绑定批准或拒绝。 + +## 18. 角色 Skill 已经“完全隔离”了吗？ + +不能这样表述。现场 apply 与独立只读检查证明的是固定七项 DevFlow Skill 策略 +在控制器归档缓存、控制器持久 Skill 缓存、Worker 本地树和 MinIO 一致，即 +`devflowPolicyVerified=true`，最新独立检查为 0 drift，六个角色 Pod 为 6/6 +Ready。结果同时明确 +`completeRoleSkillBoundaryVerified=false`：内建、平台和未知 Skill 没有被扩写 +为完整边界；OpenClaw 审计也仍为 `strongBoundaryEnforceable=false`。这是经过 +验证的窄边界，不是敌对 root 或 OS 沙箱声明；同 UID 文件检查与使用之间仍存在 +TOCTOU 风险。 + +## 19. TeamHarness 和 MCP 如何避免只信调用者自述？ + +当前 Guard 代码与测试从根权限账本读取项目风险、从持久项目状态读取来源， +直接查询 Matrix 以验证私有邀请规则和完整实际成员集合，并用 taskId 与提交摘要 +约束幂等/冲突。成功路径驱动直接使用 stdio 与 Streamable HTTP，敏感值不进入 +子进程 argv，同时校验角色×服务器配置/schema 并设置硬截止。一次 fresh T2 +现场任务已沿该路径完成：项目完成、报告关闭，validator、三种提交语义、冲突后 +读回与 Leader `effective` 均验证；项目 push 报告 2/2，对 `meta.json` 与 +`plan.md` 又分别执行了 `stat exists=true`。这些独立 stat 只证明对象存在， +不证明远端字节摘要；一次 T2 也不能替代六阶段修复或总体成功率基准。这里的 +持久 task-result 冲突语义也不能外推为 Python execution-route claim 的分布式 +exactly-once。 diff --git a/docs/submission/INTRO_500_CN.md
