# 050-mcp-interface — Tasks

> Правило: `[ ]` не начата; `[~]` в работе; `[x]` только с доказательством (команда + вывод).

## Phase 0 — OAuth skeleton + `/mcp` probe

- [x] T001 Зависимость MCP SDK/FastMCP в `backend/requirements.txt`; каркас `backend/src/mcp_server/` с монтированием `/mcp` в FastAPI app.
- [x] T002 Authorization Server на Authlib: `/oauth/authorize` (поверх существующей web-сессии: local password + ADFS OIDC), JWKS, AS metadata (RFC 8414).
- [x] T003 `/oauth/token`: authorization_code + PKCE S256 (обязателен для публичных клиентов), refresh_token с ротацией, client_credentials для service-principal.
- [x] T004 DCR (RFC 7591): регистрация публичных клиентов с first-party scope bound; список/отзыв в Admin.
- [x] T005 Resource Server: RFC 9728 metadata для `/mcp`, `401 + WWW-Authenticate`, валидация access-JWT (`aud=mcp`, jti/blacklist) на каждый запрос; `resolve_principal()` адаптер.
- [x] T005a Transport and domain input limits: server-owned request byte/JSON-depth/collection/string limits, ScenarioGraph and SQL/DSL size limits, and per-session rate limits; rejected payloads create no ToolInvocationRecord, gate, draft, run, or mutation.
- [x] T006 Refresh rotation + reuse-detection: повтор ротированного refresh токена отзывaет семейство (расширение `TokenBlacklist`); fault-injection тесты.
- [x] T007 2–3 пробных инструмента (read-only: list_environments, get_health_summary, search_dashboards) с явной регистрацией и курируемыми схемами.
- [x] T008 CI: скриптованный клиент проходит discovery → DCR → PKCE → token → `tools/list` без ручных шагов (SC-007); подключение MCP Inspector; документация в README/INSTALL. Доказательство (remediation round 1, 2026-09-03): `pytest tests/test_mcp_client_flow_http.py -q` → `2 passed` — оба потока целиком поверх реального HTTP: (a) machine-поток: RFC 9728 discovery → AS metadata (grant `client_credentials`, `client_secret_post`) → confidential DCR с одноразовым `client_secret` → `client_credentials` → signed aud=mcp токен с `principal_type=service` → `/mcp` initialize → tools/list (gated/human-only тулы невидимы) → tools/call; (b) пользовательский поток: public DCR → PKCE S256 `GET /oauth/authorize` с Bearer веб-сессии (документированный SPA-mediated consent-путь) → 302 code → обмен → identity-only токен → `/mcp` tools/list с live-RBAC (RUN_PROD-тул скрыт для RUN-юзера); wrong secret → `invalid_client`. Реализовано: грант `client_credentials` (`services/mcp_oauth.py`), `oauth_clients.secret_hash` (миграция 0017, idempotent-guard), service-principal short-circuit в `McpTokenVerifier`, AS metadata расширена. Документация: INSTALL.md §«MCP клиент». MCP Inspector подключается по тому же discovery-контракту (Streamable HTTP `/mcp`). Ограничение браузера-без-Bearer (cookie-consent HTML): **РЕШЕНО 2026-09-04 — не строим в 050**. Документированный и протестированный путь — SPA-mediated authorize: аутентифицированный фронтенд вызывает `GET /oauth/authorize` с Bearer веб-сессии (SC-007 «zero manual token management» выполнен: DCR → PKCE → code → токены автоматизированы полностью). Отдельная интерактивная consent-страница (login+consent на cookie-сессии) — новая frontend-поверхность со своим UX/i18n/security-ревью, непропорциональная first-party perimeter scope (MCPX-FR-020: только локальные клиенты). Fallback для browser-only клиента описан в INSTALL.md §«MCP клиент». Если browser-only third-party клиенты станут требованием — это отдельное продуктовое решение через architecture amendment (MCPX-FR-020 stand).
- [x] T008a DCR abuse controls: rate limits, redirect-URI validation, reviewed first-party scope bounds, admin audit/revocation, and tests proving registration cannot grant permissions or escalate scopes.
- [x] T008b Local-perimeter deployment tests and docs: reject or disable non-local MCP/LLM/VLM endpoint configuration by default; assert PII is permitted only for configured enterprise-local providers while credentials/cookies/tokens/secrets remain rejected everywhere. *(Closure review 2026-09-03: тестов на отклонение non-local эндпоинтов не найдено; секрет-гигиена provenance подтверждена — PARTIAL.)* Доказательство (remediation round 5, 2026-09-04): deny-by-default guard `Core.EndpointLocality` (`src/core/utils/endpoint_locality.py`) в choke points `LLMProviderService.create_provider/update_provider` — типизированный отказ `endpoint_not_local:<reason>` ДО персистенции (create не добавляет row, update не мутирует), route-слой маппит в HTTP 400 (не 500). Локальность: loopback/local-литералы, RFC1918/ULA private IP, enterprise DNS-суффиксы (`.local/.internal/.lan/.corp/.intranet`, расширяемо), DNS-имена с полностью приватным резолвом; нерезолвимое = fail closed; substring-spoofing (`https://api.openai.com/localhost`) отклоняется по hostname; пустой base_url (публичное SDK-облако по умолчанию) отклоняется. Escape hatches env-документированы (`LLM_ALLOW_NONLOCAL_ENDPOINTS`, `LLM_NONLOCAL_ENDPOINT_ALLOWED_HOSTS`, `LLM_LOCAL_HOST_SUFFIXES`), по умолчанию закрыты. MCP-транспорт: server-owned JSON-depth limit (typed 400 pre-dispatch) + per-session rate limit с `Retry-After` (E6) + существующие body-limit/DNS-rebinding defaults. Docs: INSTALL.md §«Локальный периметр». Тесты: `tests/test_endpoint_locality.py` (22) + `tests/test_mcp_transport_limits.py` (5) + provider/route slices → `pytest tests/test_endpoint_locality.py tests/services/test_llm_provider.py tests/api/test_llm.py tests/api/test_encryption_health.py -q` → `107 passed`. PII-часть (секрет-гигиена provenance) подтверждена closure review round 1 и E13-отклонениями authoring chain.

## Phase 1 — Parity catalog (37 tools)

- [x] T010 Каталог-реестр инструментов по доменам: env/health/tasks, git/deploy/migration/backup/maintenance, superset ops, baseline, scenario. Каждый инструмент декларирует `required_permission(resource, action)` из канонического словаря; единая серверная политика поглощает `_tool_filter`.
- [x] T011 Инструменты env/health/tasks (list_environments, get_health_summary, get_task_status, maintenance CRUD, llm status).
- [x] T012 Инструменты git/deploy/migration/backup. Доказательство: `pytest tests/test_mcp_ops_parity.py tests/test_mcp_server.py tests/test_mcp_approvals.py tests/test_mcp_maintenance.py tests/test_mcp_oauth.py -q` → `70 passed`; зарегистрированы `create_branch`, `commit_changes`, `deploy_dashboard`, `execute_migration`, `run_backup`, `run_llm_documentation`, `run_llm_validation` (curated inputs, approval-gated; reviewed dispatchers `src/services/mcp_ops_dispatch.py` в явной цепи `poll_approved_mcp_dispatches`: GitService / TaskManager git-integration, superset-migration, superset-backup, llm_documentation, ValidationTaskService).
- [x] T013 Superset-инструменты (databases/explore/sql/format/permissions/dashboard+dataset CRUD) — SQL-класс помечен risk-классом и отдельным правом. Доказательство: тот же срез `70 passed`; `superset_list_databases`, `superset_explore_database`, `superset_format_sql`, `superset_audit_permissions` (read), `superset_create_dashboard`, `superset_copy_dashboard`, `superset_create_dataset` (approval-gated), `superset_execute_sql` — permission `("plugin:superset_sql","EXECUTE")` добавлен в `rbac_permission_catalog.discover_declared_permissions` + default-deny mapping; dangerous SQL отклоняется клиентским guard. Доп. свидетельство (орт. аудит 2026-09-02): guard расширен (`safety.py`: `INTO/CALL/SET/REFRESH/VACUUM/REINDEX/ATTACH/LOAD/PREPARE/COMMENT` + опасные функции `lo_import/lo_export/pg_read_file/pg_write_file/pg_ls_dir/dblink/dblink_exec/set_config/pg_sleep` + запрет мульти-стейтментов через `;` после очистки строк/комментариев; `tests/test_core/test_superset_safety.py` — 50+ кейсов); PROD-критерий SQL-класса выравнен с `resolve_environment_execution_policy` (is_production OR stage=PROD) и переведён в терминальный отказ `production_sql_execution_rejected` вместо одобряемого, но недиспетчеризуемого гейта; `pytest tests/test_mcp_ops_parity.py tests/test_core/test_superset_safety.py -q` → `85 passed`; полный срез аудита `214 passed`; полный бекенд **11202 passed**.
- [x] T014 Baseline-домен: capture_baseline_candidate, request/decide/consume_baseline_approval, create_verification_run (паритет fixtures с tools_037). Доказательство: тот же срез `70 passed`; прямые обёртки над `candidate_capture`/`candidates.request|decide_approval`/`verification_service.create_verification_run_async` (те же сервисы, что и 037 REST-поверхность); `consume_baseline_approval` — baseline publish: approval-gated + reviewed dispatcher через one-shot `consume_approval`; полный backend suite `python -m pytest -q` → `11167 passed, 240 skipped, 1 xpassed`; ruff/compileall чистые; каталог 45/45 зарегистрирован. **Re-verified 2026-09-16:** срез `pytest -q tests/test_mcp_ops_parity.py tests/test_mcp_server.py tests/test_mcp_approvals.py tests/test_mcp_maintenance.py tests/test_mcp_oauth.py tests/api/test_mcp_parity_baseline_037.py` → **84 passed**; каталог вырос до 61 записи (version 2.3.0), baseline-домен на месте; `consume_baseline_approval` дополнен gated `publish_baseline_catalog` (T045, CLOSED 2026-09-11).
- [x] T015 Scenario-домен: `scenario_compile`/`scenario_validate`/`scenario_resolve`/`generate_draft_pack`/`request_save`/`activate_revision`/`start_scenario_run` (паритет с tools_038 и 042/044; save только из server-stored draft, activation отдельная CAS-операция).
- [x] T016 Контрактные тесты паритета: выводы MCP-инструментов сопоставлены с legacy-обёртками на общих фикстурах (SC-002). Доказательство: `pytest tests/api/test_mcp_parity_baseline_037.py -q` → `3 passed` (re-run 2026-09-16 на HEAD `4746af2f` → `3 passed in 1.79s`): request/decide baseline-approval — MCP-gate валидируется моделью `ApprovalGateResponse` и совывает с REST по operation/risk_level/required_permission/status/reason_required/target_paths + actor parity на decide; `create_verification_run` — идентичные overall_status/category statuses/evidence_refs/created_by против REST `/verification-runs`; `superset_format_sql` — идентичная строка против legacy REST `/api/agent/superset/sqllab/format` (единственный дабл — [EXT:Superset] клиент). Попутно пойман и закрыт регрессией дефект 038-резолвера: `scenario_resolve` selector-путь падал на `step.description is None` (`TypeError`) — теперь `selector_hint` пишется без конкатенации с None (`test_selector_hint_on_step_without_description`).
- [x] T017 Bounded-response дисциплина: лимит инлайн-ответа, артефакты как ref+digest.
- [x] T018 Hidden/gated матрица: admin/analyst/viewer × каталог — отсутствие права скрывает инструмент из `tools/list`; role-change виден на следующем вызове без re-consent (SC-004, SC-009).

## Phase 2 — Gates & provenance over MCP

- [x] T020 AgentAction-provenance на каждый вызов (ToolInvocationRecord): principal, tool, digest аргументов, исход, связь с AgentRun.
- [x] T021 `approval_required` конверт для негelegированных действий; durable ActionApprovalGate без side effects до решения (SC-003).
- [x] T022 Gate-инструменты как первичный путь полного цикла в клиенте: `list_pending_approvals(filter)` (+гейты от автоматизации) и `decide_approval(gate_id, confirm|deny, reason)` с CAS, обязательным reason для high-risk confirm, отказом service-principals и typed-ошибками на expired/replayed; web gate cards — равноправный рендер тех же строк (SC-003).
- [x] T023 E2E-walkthrough: внешний клиент создаёт сценарий фикстурного дашборда end-to-end → revision в registry (SC-001). Доказательство: `pytest tests/test_mcp_scenario_e2e.py -q` → `2 passed`: один человеческий принципал с реальным `scenario:EDIT`/`scenario:RUN` (без RBAC-стабов) проходит `tools/list`-видимость → `create_authoring_session` → `propose_graph_revision` (server-derived op) → `get_graph_diff` → `promote_to_scenario` (awaiting_user_review) → `request_save` → `ScenarioRevision(candidate)` в registry → 038 `inspect_scenario`/`scenario_resolve`/`validate_scenario` поверх MCP → `activate_revision` → `entry.current_revision_id` продвинут отдельным CAS; второй тест — принципал без `scenario:EDIT` не видит и не может вызвать save/activate. Транспортный уровень (initialize → mcp-session-id → tools/list → tools/call) покрыт скриптовым клиентом T008.
- [x] T024 Gated-вызовы по контексту: PROD-окружение и baseline publish возвращают `approval_required` при видимом инструменте (hidden-vs-gated, MCPX-FR-018).
- [x] T024a Context revalidation: environment-policy and provider-binding fingerprints are rechecked at dispatcher admission and before provider I/O; target reclassification or binding drift invalidates a prior gate without I/O (SCEX-FR-026).
- [x] T025 Checkpoint-инструменты: `list_checkpoints` + `decide_checkpoint(run_id, disposition, expected_version)` через тот же CAS/аудит, что и монитор 045; user-principal only (service → permission_denied); тест что автоматизация не имеет пути к чекпоинтам (MCPX-FR-019). Доказательство (после closure-review داунгрейда, 2026-09-03): `pytest tests/test_mcp_checkpoints.py -q` → `3 passed`: каталог `("scenario","RUN")` + `service_allowed=False` на оба инструмента; сервис-принципал не видит и не может вызвать; list-проекция pending/decided чекпоинтов рана; decide повторяет REST `/human/decision` (pending-резолв на сервере, CAS `decision_version`, `continue_after_human_decision`, step→passed/`HUMAN_*`, run→queued/executing); stale expected_version → `conflict` без потребления; отсутствие pending/рана → `checkpoint_not_found`. (Closure review 2026-09-03 зафиксировал прежний фиктивный [x]; закрыт реальной реализацией.)
- [x] T026 AgentAuthoringWorkspace operations: `create_authoring_session`, `propose_test_plan`, `start_exploration`, `get_exploration_result`, `propose_graph_revision`, `get_graph_diff`, `promote_to_scenario`; persistent server-owned state, provenance, idempotency and workspace CAS.
- [x] T027 Authoring sandbox contract tests: isolated runtime, origin/API/action allowlists, no shell/credential/filesystem escape, limits, cancellation, receipts, artifact ownership and zero production side effects; retain exploratory traces/screenshots/diagnostics as bounded refs.
- [x] T028 Authoring promotion E2E: sandbox output -> typed proposal -> deterministic 038 compile/validate -> user diff review -> 042 handle-based save -> immutable revision; reject raw code/URLs/cookies/secrets/paths/caller digests and keep code-backed production execution unimplemented. Доказательство: `pytest tests/test_mcp_authoring_promotion_e2e.py -q` → `8 passed`: полный прогон через `tools/call` — `start_exploration` теперь ставит `queued` при зарегистрированном раннере (wiring `provider_available=get_registered_runner() is not None`; регистрация `default_runner`+deployment context в `bootstrap_live_execution_composition`) → реальный `execute_scheduled_exploration_dispatch` из потокового контекста планировщика → `exploration_passed` с observations/proposed_graph/evidence_ref (`draft:exploration-*`) при [EXT:Browser]-дабле; `get_exploration_result` остаётся ограниченной проекцией без утечки наблюдений; значение `observed_dashboard_title` в сохранённой ревизии выводится только из наблюдения; `propose→promote→diff→request_save→activate` завершается `current`-ревизией без продвижения до отдельного CAS-активации. Негативные ветки: typed ops с SQL/`../`/`\\`/`drop` отклоняются до предложения и CAS; exploration-spec с code-токенами и незарегистрированными действиями не персистируется; `GraphRevisionInput`/`PromoteScenarioInput`/`RequestSaveInput`/`ActivateRevisionInput`/`ExplorationInput` структурно отвергают `digest`/`content_hash`. Дополнительно: диспетчерский soak (`test_mcp_ops_parity.py`) — 3 цикла поллера, каждое одобренное действие диспетчеризуется ровно один раз (`14 passed`). Полный срез: `83 passed` (8 файлов MCP-вертикали); полный backend suite **11182 passed**.

## Phase 2b — Initial scenario and automation parity

- [x] T029 Implement `ScenarioRegistry.CreateInitial` and `bootstrap_authoring_scenario`; prove a fresh external MCP client creates a first registry scenario without a seeded base revision. Evidence: `tests/test_mcp_initial_scenario_e2e.py` creates real `AgentRun`/`DraftArtifact` rows and drives `bootstrap_authoring_scenario` without a seeded registry; replay and conflicting idempotency are covered by `tests/test_mcp_t029_bootstrap_automation.py`.
- [ ] T029a Add typed InitialScenarioIntent/TestPackProfile validation and server-owned metric/filter/selector/baseline bindings; unresolved requirements must be `preview_only`, never guessed.
- [x] T029b Expose 046 schedule, trigger-rule, policy and automation-metrics management through curated MCP tools with REST-equivalent RBAC, idempotency and PROD gate behavior. Evidence: curated tools and catalog entries in `src/mcp_server/tools_automation.py`/`rbac_server.py`, idempotency migration `alembic/versions/0018_automation_idempotency.py`, and `tests/test_mcp_t029_bootstrap_automation.py` plus RBAC catalog tests.
- [x] T029c Add fresh-DB MCP E2E for bootstrap → visible registry entry → revision activation → manual run, plus scheduler eligibility/PROD-gate integration evidence. Evidence: `tests/test_mcp_initial_scenario_e2e.py` verifies fresh bootstrap, current revision, refusal to run an un-promoted bootstrap revision (`BOOTSTRAP_REVISION_NOT_RUNNABLE`), a pinned manual run against a genuinely materialized revision, human-step schedule rejection with zero side effects, and an idempotent PROD approval gate; focused MCP regression set: `145 passed` (2026-09-06).

## Phase 2c — Server-owned handle layer (root-cause closure of ADR-0023; contracts: 038 `ScenarioGraph.ServerOwnedPipeline` amendment 2026-09-06, 042 `ScenarioRegistry.DataModel` amendment, 050 stage table status note)

- [x] T029d Persist the 038 handle layer: `CompiledScenarioHandle`/`ValidationResultHandle`/`DraftPackHandle` tables (immutable, append-only, owner_principal+agent_run binding, digest/content_hash columns per 038 amendment) + Alembic migration + server content-store persistence of the canonical `DashboardTestScenario` bytes (`ScenarioGraph.Models.CanonicalBytes`) behind `canonical_bytes_ref`. Minting happens ONLY at the persisted REST boundaries (`api_compile_scenario`/`api_validate_scenario`/`api_resolve_scenario`/`api_draft_pack`); pure compiler functions keep `@SIDE_EFFECT None`. Single-consumption (`consumed_by_revision_id`), cross-binding rejection, GC via 036 draft-retention. Evidence: `src/models/scenario_handles.py`, `src/services/dashboard_testing/scenario/handles.py` (idempotent mint / verify / consume / purge), migration `0019_scenario_handles`, REST minting in `api/routes/dashboard_testing/scenario.py`, authority tests `tests/services/dashboard_testing/scenario/test_handles.py` (3 passed).
- [x] T029e 042 create consumes handles: `create_scenario`/`create_initial` re-verify handle ownership/binding/`save_eligible`, materialize `graph_snapshot` = canonical `DashboardTestScenario` JSON from handle bytes inside the create transaction, and write `OutboxEvent(type=materialize_revision)` + `RevisionMaterialization(pending)`; implement the idempotent reference-artifact worker (`scenario.yaml`/reference `runner.plan.json`) or record an explicit descope decision. `BOOTSTRAP_REVISION_NOT_RUNNABLE` demotes from primary guard to defense-in-depth; `api_create_scenario` stops hardcoding `materialization_status="materialized"`. Evidence: handle-first branch in `registry/create.py` (materializes full canonical graph + server-owned `action_registry_version/hash`), `src/models/scenario_materialization.py` + migration `0020_scenario_materialization`, worker `registry/materialize.py::materialize_pending_revisions` (idempotent, pending→materialized/failed), `api_create_scenario` returns the actual `RevisionMaterialization.status`.
- [x] T029f MCP minting surface: new `register_draft_pack` write tool returns bounded server-issued handle ids; `bootstrap_authoring_scenario` accepts ONLY stored handle ids (transitional `compile:{run_id}:{digest}` string check removed from `create_initial`); catalog bumped `1.0.0 → 2.0.0` (breaking bootstrap handle semantics) with pinned-major ritual `PINNED_CATALOG_MAJOR=2`. Legacy REST `POST /scenarios/{id}/revisions` raw-`graph_snapshot` path retired (returns `410 GONE` `REVISIONS_RAW_GRAPH_RETIRED`; the server-side `create_revision` service remains for the 043 editor save path). Also reclassified `generate_report` out of `_MUTATING_ACTIONS` (local draft report, no external side effect), bumping `ACTION_REGISTRY_VERSION 038.1.0 → 038.2.0` (fingerprint + `scenario_execution/graph.json` fixture updated).
- [x] T029g Full-chain fresh-DB MCP E2E without REST crutches and without hand-seeded revisions: `register_draft_pack`→`bootstrap_authoring_scenario`→direct `start_scenario_run` on a bootstrapped current revision (now materialized) returns `queued`. Evidence: `tests/test_mcp_initial_scenario_e2e.py` rewrote `_pack()` to drive the MCP `register_draft_pack` tool. PostgreSQL concurrency: `verify_handle_chain` uses `SELECT ... FOR UPDATE` + `populate_existing()` to serialize handle consumption, proven by `tests/integration/test_scenario_handle_concurrency.py` (one winner + one `HANDLE_CONSUMED` across two threads on a real PostgreSQL container; `--run-integration` green). *(Amended 2026-09-07, Doc.Adr.ADR0024/T029j: the claim "without REST crutches" did not cover the AgentRun prerequisite — `_pack()` inserted the `AgentRun` row with a raw ORM constructor unreachable for any external MCP client; the field run of 2026-09-07 proved `register_draft_pack` therefore denied every real client. `_pack()` now creates the run through the production `create_agent_run` service boundary with honest test metadata; full external reachability closes at T029i and is pinned by `tests/test_mcp_agent_run_reachability.py` (strict xfail).)*
- [x] T029h Inspect-stage decision: **resolved as hybrid option C (2026-09-06)** — no persisted `InspectionContextHandle`; instead (a) new MCP read tool `inspect_dashboard_context` exposes the existing live resolver (`BaselineEngine.QueryModel.Inspect` via `GET /query-model` service) returning the full authoritative `DashboardQueryModel` + fingerprint for the agent to echo into compile; (b) the register boundary (`register_draft_pack`) evaluates `context_authority` by RECOMPUTING the fingerprint from the client-carried `dashboard_context.query` (claimed fingerprints are ignored — C2) against a live inspection, with sentinel/degraded fingerprints (`""`, `sha256:error`) never verifying (C1), unreachable/unconfigured environments failing OPEN to `unverified` (C3), and falsifiable model-shape claims on live environments rejecting typed (`CONTEXT_FINGERPRINT_MISMATCH`, `CONTEXT_QUERY_MODEL_REQUIRED`, `CONTEXT_ENVIRONMENT_MISMATCH`) — C5 inspect-first; (c) the marker persists on `DraftPackHandle.context_authority` (migration `0021_context_authority`), materializes into `graph_snapshot` at 042 create, and `ScenarioExecution.Runner.Start` refuses PROD dispatch on an explicit non-verified marker (`CONTEXT_AUTHORITY_REQUIRED_FOR_PROD`, zero side effects; missing marker = legacy, allowed); (d) X1 smuggling closure: validator `_check_dashboard_context` recursively rejects `query_context` keys and SQL text inside `dashboard_context`. Catalog minor bump `2.0.0 → 2.1.0` (additive, pinned major untouched). Evidence: `tests/services/dashboard_testing/scenario/test_context_authority.py` (7), validator X1 tests (+2), `test_prod_start_enforces_context_authority_marker`, E2E marker-propagation + PROD-block assertions; broad regression `1338 passed`; `alembic heads` → `0021_context_authority`. Residual: editor promote/save path (`request_save` revisions) does not yet carry the marker — PROD gate treats it as legacy-allowed; tightening requires authority evaluation in the 043 save boundary (follow-up, not scoped by T029h).

*(Orthogonal code review 2026-09-06, [ADR-0023](../../docs/adr/ADR-0023-mcp-scenario-pipeline-handle-gap.md); specs amended the same day and the durable handle layer implemented — 038 `contracts/modules.md`, 042 `data-model.md`/`contracts/modules.md`, 050 `spec.md`): the bootstrap→run happy path is realizable through MCP alone (`register_draft_pack` → `bootstrap_authoring_scenario` → direct `start_scenario_run` on a materialized current revision). Phase 2c residuals now closed: `api_create_scenario` returns real `materialization_status`, legacy REST `POST /scenarios/{id}/revisions` retired (410 GONE), PostgreSQL single-consumption concurrency proven (`SELECT ... FOR UPDATE` + `populate_existing()`; `tests/integration/test_scenario_handle_concurrency.py` green on real PostgreSQL). T029h resolved as the hybrid (see above); follow-up residuals closed 2026-09-07: outbox worker wired into the scheduler poll loop (`scenario_revision_materialization`, 30s, singleton/coalesced, durable-tick test), REST `api_draft_pack` evaluates `context_authority` at parity with the MCP register boundary (async, typed 422 on falsifiable mismatch), and the 043 editor save path provably inherits the server-owned marker (`test_save_proposal_inherits_server_context_authority_marker`). Known-accepted limitation: legacy/NULL markers stay PROD-allowed by design; full-suite regression `3360 passed`.)*

## Phase 2d — Field-run remediation (2026-09-07 sales-prod external MCP run; [ADR-0024](../../docs/adr/ADR-0024-mcp-agent-run-external-boundary.md); spec: MCPX-FR-027/028/029, release-gate rows `E2E-EXT-001/002`, `CAP-001`, `DISP-001`, `TEST-001`)

> Источник: `docs/2026-09-07-sales-prod-mcp-run.md` — первый полевой прогон внешнего MCP-клиента против
> ss-prod Sales Dashboard (ID 11). Все звенья цепи реализованы, но external-клиент упёрся в
> `DRAFT_PACK_ACCESS_DENIED`: `register_draft_pack` требует principal-owned `AgentRun`, а MCP-операции
> создания AgentRun не существует (единственная creation-поверхность `POST /api/agent/runs` — REST/web-session,
> MCP-токены `aud=mcp` на ней не аутентифицируются). Вертикальный E2E маскировал разрыв raw-ORM-seed'ом.

- [x] T029i MCP AgentRun surface (MCPX-FR-027): typed `create_agent_run` + `get_agent_run` tools wrapping the existing `Services.AgentRuns.Service.Create`/snapshot boundary — curated bounded input (UIContext v2: `objectType=dashboard`, numeric `objectId`, `envId`, `route`, `contextVersion=2`, `intent=build_dashboard_test_scenario`; `extra=forbid`; optional `idempotency_key`), permission `("dashboard:testing","EXECUTE")` at REST parity, `service_allowed=False`, idempotent active-run reuse, bounded snapshot projection (`get_agent_run` returns the ownership-scoped `AgentRunSnapshot` fields only). Catalog additive bump `2.1.0 → 2.2.0`; update SC-004 exact-set fixtures (`tests/test_mcp_rbac_visibility.py`) and `tests/api/test_admin_mcp_catalog.py` mirrors. Closure evidence: convert `tests/test_mcp_initial_scenario_e2e.py` to the FULLY external chain (`create_agent_run` → `register_draft_pack` → `bootstrap_authoring_scenario` → `start_scenario_run`), remove the `strict=True` xfail marker in `tests/test_mcp_agent_run_reachability.py` and make it green (`E2E-EXT-001`). Доказательство (2026-09-07): новый seam `src/mcp_server/tools_agent_run.py` (`McpServer.ToolsAgentRun`, 155 LOC) — `create_agent_run` (server-pinned objectType/route/contextVersion/intent; caller владеет только dashboard/environment/name/idempotency_key → conversation-reuse; продуктовая форма run: status RUNNING + `run_started` event) и `get_agent_run` (bounded-проекция + draft_count; чужой/неизвестный id → typed not_found без existence oracle); catalog +2 (`EXECUTE`/`READ`, human-only), `MCP_CATALOG_VERSION=2.2.0` (PINNED_CATALOG_MAJOR=2 не тронут); registration seam в `_build_probe_server` (automation → agent-run → scenario). Тесты: `tests/test_mcp_agent_run_tools.py` (5: продуктовая форма+envelope keys, idempotent replay + env-scoping, structural rejection, ownership read + not_found, RBAC denial by name); `test_mcp_initial_scenario_e2e.py` конвертирован в fully external chain (`create_agent_run` через `tools/call`, ноль не-MCP seeding); xfail-маркер в `test_mcp_agent_run_reachability.py` снят — requirement pin зелёный на живом каталоге; catalog-pin `test_mcp_server.py` +2 имени +4 assertion. RBAC-зеркала правок не потребовали (analyst без EXECUTE/READ —derived-наборы). Gate: 8-файловый срез `70 passed`; полный backend suite `11357 passed`.
- [x] T029j Test-honesty remediation (ADR-0024 §3, binding rule): vertical/E2E tests obtain every prerequisite through a boundary the principal under test can reach; raw-ORM seeding of a chain prerequisite in a test claiming external reachability is forbidden. Executed: `test_mcp_initial_scenario_e2e.py::_pack()` replaced the raw `AgentRun(...)` insert with the production `create_agent_run` service boundary with honest test metadata; new `tests/test_mcp_agent_run_reachability.py` pins (a) the external-reachability REQUIREMENT as `strict=True` xfail (flips the suite red the moment `create_agent_run` lands without spec follow-through) and (b) the current typed zero-side-effect denial (`DRAFT_PACK_ACCESS_DENIED`, no handle rows). Evidence: see `TEST-001` row in spec.md release gates (targeted pytest green 2026-09-07). *(Update 2026-09-07, T029i closure: строгий xfail-пин сработал как спроектирован — конвертирован в обычный requirement-тест (unmarked, green) вместе с конвертацией вертикали в fully external chain; denial-pin сохранён.)*
- [x] T029k Context-authority-derived capability map (MCPX-FR-028; 038 amendment 2026-09-07): server-owned derivation of `capabilities`/`has_dataset_fields` from the authoritative `DashboardQueryModel` (the same live inspection `context_authority` binds), environment policy and provider readiness — exposed through `inspect_dashboard_context` (derived-capability section) and consumed by the persisted compile boundaries (MCP `scenario_compile` + REST `api_compile_scenario`); caller-declared capabilities remain accepted only as an explicit subset narrowing, never as an authority that downgrades verifiable facts into `human_checkpoint`; unresolved facts stay `needs_context`/`needs_selector`/`needs_baseline`; genuinely unsafe PROD mutation contexts keep `human_checkpoint`; HumanStep revisions remain automation-ineligible (SCEX-FR-004a stands). Evidence: `CAP-001` row + capability-derivation unit/E2E tests. Доказательство (2026-09-07): новый `src/services/dashboard_testing/scenario/capability_authority.py` (236 LOC, `ScenarioGraph.CapabilityAuthority`): `derive_capabilities` — только верифицируемые факты (native_filters; text_filter по STRING-фильтру; time_rollover по DATE/TIME/TIME_GRAIN; table_filter+pagination по executable table-viz; xlsx_export из capabilities-флага; dataset_field_read+has_dataset_fields по accessible dataset с колонками; browser — только при readiness-факте из T040-снимка composition-root), `NEVER_DERIVED` = row_edit/bulk_edit/persistence_refresh/safe_test_data/safe_clock_fixture/cross_dashboard (unsafe-mutation автоматизация метаданными невозможна — module @INVARIANT); `merge_capabilities` — derived-wins в ОБЕ стороны (declared-false не понижает проверяемую правду; declared-true не фабрикует) + overrides-аудит; legacy/unparseable payload → дословный caller-declared passthrough (register-time context_authority остаётся жёстким гейтом). Wiring: MCP `inspect_scenario` (+additive `capability_authority` секция), `inspect_dashboard_context` (+`derived_capabilities`), REST `api_compile_scenario` (parity через общий `build_capability_authority` choke point + additive секция). Тесты: фикстура `query_model_sales.json` (форма sales-стенда); unit truth-table `tests/services/dashboard_testing/scenario/test_capability_authority.py` (7, включая **CAP-001 classification-fix через `map_all`**: полевого shape декларации → B01–B04/T01–T03 `automated`, C04–C06 `unsupported`, B05–B09/C01–C03/C02/C07 легитимно `human_checkpoint`); tool-level `tests/test_mcp_capability_authority.py` (3: derived-wins overrides `["text_filter","xlsx_export"]`, legacy caller_declared, derived_capabilities в inspect-ответе); REST-parity pin `test_scenario_routes.py::test_capability_authority_derived_wins`. Браузер-readiness seam запинен monkeypatch (детерминизм против глобального composition-root состояния в full-suite). Gate: 5-файловый срез `67 passed`; полный suite `11357 passed`.
- [x] T029l Disposition vocabulary clarity (MCPX-FR-029; 044/045 amendment 2026-09-07): the 044 lifecycle mapping (`confirm`→`passed`, `false_positive`/`inconclusive`→`inconclusive`, aliases `pass`/`fail`) is immutable and stays; human-facing wording aligns to the persisted outcome — RU labels «Подтвердить соответствие» / «Проблема не подтверждена» / «Недостаточно данных» (+ EN parity), confirm-button restyled from `bg-destructive` to a positive token, `decide_checkpoint`/`decide_approval` MCP tool descriptions and 045 monitor docs carry the outcome table, vitest pins updated (`WaitingForMeView.test.ts`, `HumanCheckpointPanel` tests). Evidence: `DISP-001` row. Доказательство (2026-09-07): `waiting_disposition_confirm/false_positive` в ru/en `dashboard-testing.json` именуют персистентный исход (confirm→passed: «Подтвердить соответствие»/"Confirm conformance"; false_positive: «Проблема не подтверждена»/"Issue not confirmed"; inconclusive без изменений); confirm-кнопки `HumanCheckpointPanel.svelte` и `WaitingForMeView.svelte` переведены `bg-destructive` → `bg-primary` (прецедент approve-кнопки ApprovalDecisionPanel) + @RATIONALE в контрактах компонентов; API-вокабуляр не переименован (continuity аудита/CAS); MCP `decide_checkpoint` docstring (видим в tools/list) несёт immutable outcome-mapping и правило «confirm = проверка пройдена, никогда не подтверждение дефекта»; vitest-пины обновлены (`RunMonitorViews.test.ts` — новый DISP-001 pin лейбла+стиля+dispatch "confirm", `WaitingForMeView.test.ts`, `run.ux.test.ts`). Lifecycle-маппинг не менялся — backend-тесты decision-пути зелёные без правок. Gate: frontend `3507 passed` (206 файлов), lint `0 errors / 364 warnings` (baseline), `npm run build` OK.
- [x] T029m Live-stand replay of the field run: after T029i/T029k/T029l, re-run the 2026-09-07 sales scenario externally against the live stand — `inspect_dashboard_context` → derived-capability compile/validate → `create_agent_run` → `register_draft_pack` → `bootstrap_authoring_scenario` → `start_scenario_run` (PROD gate observed, no unexpected high-risk approvals) → `list_checkpoints`/`decide_checkpoint` human loop with aligned labels; retain the run report beside `docs/2026-09-07-sales-prod-mcp-run.md`. Evidence: `E2E-EXT-002` row. **Status (2026-09-11): CLOSED.** Committed replay client `specs/044-dashboard-scenario-execution/prototype/live_mcp_replay.py` (transport-only adaptation of the proven scripted OAuth/PKCE + tool-chain flows, no new client machinery) replayed the FULL external chain on the live stand with zero non-MCP seeding: inspect (derived capabilities) → `create_agent_run` `a6168c7d…` → compile B01 (capability_authority `derived`) → validate → draft-pack `save_eligible` → `register_draft_pack` (**context_authority verified**) → bootstrap (scenario `e2687f03…`, current revision) → PROD start `pending_approval` (identical retry = one durable gate) → approval → live execution to an honest typed terminal (`capture_screenshot` **passed** with 8 durable refs; `apply_native_filter` typed `BROWSER_ACTION_NOT_SUPPORTED` — no synthesized PASS). Full trace + two fail-closed defects the replay exposed and fixed (binding resolution for identity-less compiled steps; per-step target-identity stamping at bootstrap materialization) + D5 binding-admin live exercise: `docs/2026-09-11-sales-prod-mcp-replay.md`. The human-checkpoint loop was exercised live by the companion `live_mcp_human_loop.py` (compiled B05 HumanCheckpoint → PROD gate → `waiting_human` → MCP `list_checkpoints` decision_version 1 → `decide_checkpoint confirm` decision_version 2 CAS → terminal `passed`), so every element of this task's formulation is covered. The baseline-pinned variant remains blocked on the Gitea PAT (050 T045 / T046-pin).

## Phase 3 — Frontend decommission (flag-driven)

- [ ] T030 Replace historical HandoffSurface/agent entry with ordinary manual scenario editor; remove copy-prompt, agent launch/workspace and proposal-generation UI. Previous handoff implementation is history, not current acceptance.
- [x] T031 Скрыть `/agent`, AssistantChatPanel, кнопку «Ассистент» в TopNavbar за флагом; обновить link-integrity тесты.
- [ ] T032 Retire `/api/assistant/*` и прокси `/api/agent/gradio`; retention-настройки assistant скрыть. *(Closure review 2026-09-03: на HEAD роутеры `/api/assistant` и `agent_*` смонтированы безусловно (app.py), retention-UI в SystemSettings жив, frontend `api/assistant.ts` в поставке — фиктивный [x]. Флаг удалён в T041, поэтому retirement теперь безусловный.)*
- [x] T033 vitest/build/link-integrity зелёные при включённом флаге демонтажа.

## Phase 4 — Removal

- [x] T040 Удалить сервис `agent/` из run.sh и compose-профилей (порт 7860); обновить AGENTS.md/INSTALL.md. Доказательство: `rg "agent|7860" run.sh build.sh docker-compose.yml docker-compose.enterprise-clean.yml` → пусто (кроме исторического секьюрити-комментария); `bash -n`/`yaml.safe_load` чистые; стенд `./run.sh --skip-install` поднимает только :8000+:5173 (7860 отсутствует, `curl /api/ready` → ready, Playwright-проход до хендоффа зелёный); `run.sh`/`build.sh`/`AGENTS.md`/`INSTALL.md` обновлены; из `build.sh` убраны `build:agent`, `bundle:agent`, `bundle:embeddings` и агентский сервис генерируемого деплой-композа/манифеста; из обоих nginx-конфигов убран `location /api/agent/gradio`.
- [x] T041 Удалить код чата: agent/src (app, langgraph_setup, tools*.py, _confirmation, middleware...), frontend agent/assistant компоненты, i18n, типы. Доказательство: `agent/` удалён целиком; удалены `docker/Dockerfile.agent`, `docker/agent.entrypoint.sh`, `backend/tests/test_gradio_proxy_config.py`; во фронтенде удалены `components/assistant/*` (кроме универсального `MarkdownRenderer`), чат/ран/драфт артефакт компоненты, `components/agent/dashboard-testing/` (ScenarioWorkspace-ветка), `models/AgentChat*`, `AgentRunModel`, `DashboardScenarioWorkspaceModel`, `stores/assistantChat`, флаг `MCP_DECOMMISSION` (vite define/`config/mcp.ts`/`global.d.ts`), gradio-прокси из `vite.config.js`; `/agent` рендерит только `HandoffSurface` (безусловно), навбар-кнопка ведёт на хендофф; `npm run test -- --run` → **3454 passed**, `npm run lint` → 0 errors, `npm run build` → OK; полный бекенд **11199 passed** (минус тесты удалённого грдио-прокси), 16 сиротских тестовых файлов чата удалены.
- [x] T042 Финальные правки спек 036–047: перенести drift-amendments из статуса «planned» в «done» со ссылками на доказательства. Доказательство: во всех 12 спеках (036–047) секции `## Drift Amendment — MCP Interface` получили строку `**Status (2026-09-02): done**` со ссылками на `specs/050-mcp-interface/tasks.md` (T012–T028), T030–T033 и чекпоинты `specs/WORKSTATE-043-047.md`. **Re-verified 2026-09-16 (grep):** 11 spec-файлов несут секцию Drift Amendment; 040/041 — дословный маркер `Status (2026-09-02): done`; 036/037/038/042–047 — пост-closure-review формулировка «reported done (2026-09-02); not production-readiness evidence» с теми же ссылками (более строгая, принята как эквивалент).
- [x] T043 Полный прогон backend/frontend suites + стенд без 7860 (SC-005). Доказательство: `python -m pytest -q` → **11199 passed, 240 skipped, 1 xpassed**; `npm run test -- --run` → **3454 passed** (197 файлов); `npm run lint` (0 errors) + `npm run build` — зелёные; локальный стенд после демонтажа работает без порта 7860 (см. T040) и отдаёт рабочий хендофф на `/agent`. **Browser E2E (изолированный стенд):** `docker compose -p ss-tools-e2e --env-file .env.e2e -f docker-compose.e2e.yml up -d --build db backend frontend` (свежая БД, bootstrap admin/admin123, backend :8103 healthy, frontend :8102 healthy, порт 7860 отсутствует) → `npx playwright test e2e/tests/login.e2e.js e2e/tests/agent.e2e.js` → **6 passed** (двойной прогон, Chromium): login-поток (форма/успех/ошибка неверных кредов) и post-decommission агентский роут (хендофф-поверхность, ноль чат-элементов, deep-link с context-параметрами остаётся на хендоффе); стенд снесён `down -v`. E2E-фикстарелы: устаревший ambiguous `locator('nav')` (strict mode: 3 nav-элемента) → `.first()` в login/smoke; regex ошибки входа дополнен `incorrect|неверн` (бэкенд отдаёт passthrough-detail); `agent.e2e.js` переписан под handoff-контракт (T01-T03), `dashboard-scenario-ui`/`agent-scenario-run` — ссылки на чат-UI заменены на handoff-маршрут. Дополнительно: живой admin-walkthrough на dev-стенде (8000/5173) подтвердил login→dashboards→handoff(0 textarea/0 conversation-узлов)→runs-center (скриншоты /tmp/kilo/happy-path/09–12).

## Production readiness — 2026-09-08 (MCPX-FR-030)

Historical [x] rows above retain only their dated local/transport evidence; they do not prove current production readiness. Reopened rows were contradicted by the audited gaps. Removed frontend/agent paths are historical, not implementation prerequisites. New acceptance is **implemented=false / OPEN**.

Contract: [Contract-complete public parity](contracts/modules.md).

- [ ] T044 [P0/P1/P2] REST/MCP lifecycle/read/auth errors and disabled automation validation are identical; service principal cannot decide human gate. Implement at the existing 050 domain boundary; verify with independent hardcoded fixtures and retain command/evidence references in traceability.md. **Status (2026-09-11):** offline parity tests green; live REST-only canary v2 exercised start→gate→approve→dispatch (`4eebfab3`); the live MCP-external replay (T029m CLOSED, `docs/2026-09-11-sales-prod-mcp-replay.md`) exercised the same lifecycle through `/mcp` with the identical typed start/gate/terminal outcomes — remaining: dedicated REST-vs-MCP error-shape parity fixtures for this matrix.
- [x] T045 [P0/P1/P2] consume/publish failures return typed errors/pending state with no legacy fallback; every prerequisite is externally MCP-reachable. Implement at the existing 050 domain boundary; verify with independent hardcoded fixtures and retain command/evidence references in traceability.md. **Status (2026-09-11): CLOSED.** Consume path typed fail-closed (`bbbd4ccf`, live-proven); publication is now externally MCP-reachable through the curated gated tool `publish_baseline_catalog` (human-only, `scenario` RUN_PROD, `requires_approval`) executing the 037 publication-worker contract via `ScenarioExecution.PublicationWorker` + durable `publication_operations` (migration `0023`): idempotency by key, envelope validation (resolver-canonical), branch-head CAS, commit/published receipts, failure retention + reconcile of the same commit; REST parity `POST/GET /api/catalog-publications`. LIVE evidence (`docs/reports/agentic-runtime-live-mcp-publish-t045-2026-09-11.md`): MCP gate `approval_required` → `decide_approval` → dispatch → `published` (commit `abce63db…`, receipt head 3f782574→abce63db) + moved-HEAD canary → typed `PUBLISH_HEAD_MOVED` with a durable `publish_failed` row. Offline: `tests/services/dashboard_testing/execution/test_publication_worker.py`, `tests/api/test_catalog_publications_api.py`, `tests/test_mcp_ops_parity.py`.
- [x] T046 [P0/P1/P2] Fresh external-client chain preserves authoritative context and complete baseline pin without raw ORM/REST repair; no frontend agent controls/routes/requests. Implement at the existing 050 domain boundary; verify with independent hardcoded fixtures and retain command/evidence references in traceability.md. **Status (2026-09-11): CLOSED.** Context authority: fresh REST chain (canary v2 `4eebfab3`) and fresh MCP chain (T029m) preserved the server-resolved binding and verified context (`context_authority=verified`). Complete baseline pin: (a) the MCP-external chain with `--baseline` (`live_mcp_replay.py --baseline`, no raw ORM seeding) compiled the baseline capability, started with the published-catalog selector, and carried a full `runner_plan.baseline_pin` (set/version/digest from the published envelope); (b) the REST canary v4 (`ace916a0…`, then re-run `adeabe63…`) proved the walker stamps that same pin into the persisted `AgentEvaluation.baseline_pin` (`plan pin == record pin`, strict equality asserted) — `docs/reports/agentic-runtime-live-canary-v4-baseline-pin-2026-09-11.md`. No raw ORM/REST pin repair; frontend agent controls remain absent (2026-09-10 evidence).

## Design Amendment implementation tasks — 2026-09-17/18

- [x] T047 [P0] Investigation MCP tools + RBAC/human-only writes + catalog 2.4.0. **CLOSED:** `23414f9a` + `5eea72bc`, 73 focused green.
- [x] T048 [P0] `set_step_inputs` and `set_step_evaluation` through propose_graph_revision/EditOperation parity. **CLOSED:** `534d488f`/`f123210b` + `87a90f6f`.
- [ ] T049 [P1] `propose_baseline_selection` MCP surface for curated coordinates/review handle; observatory non-gating.
- [ ] T050 [P1] `exploration_step` read-only sandbox action with CAS/receipts; reuse 044 browser session; no second Playwright stack.
- [x] T051 [P0] Complete REST/MCP lifecycle/error parity (prior T044 residual), including disabled-action/investigation tools. **CLOSED 2026-09-22:** shared `classify_start_error` in `start_run.py` consumed by REST and MCP (removes the raw-text vs RUN_START_CONFLICT divergence); `tests/test_mcp_rest_error_parity.py` 12+ vectors (env/baseline codes/idempotency/conflict/disabled action/disabled automation/investigation RBAC/unauthenticated + service-principal human-gate denial + MCP no-bypass on the case ACL); 17 green.

Frontend boundary for this package: manual CRUD/editor, human review/approval, monitoring and read-only evidence/evaluation only; all agent interaction is external MCP. No agent chat/prompt/assistant editing/proposal generation/workspace/start/handoff controls. Runtime removal is OPEN, not performed by this spec refresh. Optional approved performance baseline is outside scope.
