+# Отчёт: Задание A2 — закрытие пробелов контракта и релизная инфраструктура
+
+Дата: 2026-08-21
+
+## Идентификаторы и границы
+
+- Base SHA: `e8a404be035fa04b5f76e3e572c6539fba0e83e4` (актуальный `origin/main` на старте).
+- Ветка: `antigravity/contract-gaps`.
+- Контракт: `docs/UI_STATE_CONTRACT.md` обновлён до версии **1.1** первым шагом.
+- Тег `v0.1.1` **НЕ создавался**.
+- Файлы UI (`src/antigravity_provider/router/ui/**`, `hermes_hub_app.py`, `tests/test_ui_*.py`) **НЕ изменялись** (`git diff --name-only` по этим путям полностью пуст).
+
+## Реализовано и закрыто
+
+### 1. Канонические публикаторы событий (Gap 9, P0-1)
+- Для каждого объявленного события реализован канонический метод/вызов в `HubStateStore`:
+  - `EVENT_ACCOUNT_UPDATED`: `apply_delta_account_updated` публикует payload `{profile_id, profile, generation, seq}`.
+  - `EVENT_ACCOUNT_ADDED`: `apply_delta_account_added` публикует payload `{provider, profile_id, profile, generation, seq}`.
+  - `EVENT_ACCOUNT_REMOVED`: `apply_delta_account_removed` публикует payload `{provider, profile_id, generation, seq}`.
+  - `EVENT_ACCOUNT_AUTH_CHANGED`: `publish_auth_changed` публикует payload `{provider, profile_id, auth_state, profile, generation, seq}`.
+  - `EVENT_QUOTA_UPDATED`: `apply_delta_quota_updated` публикует payload `{provider, profile_id, snapshot, quota_snapshot, generation, seq}`.
+  - `EVENT_ROUTING_UPDATED`: `apply_delta_route_changed` публикует payload `{role_id, active_profile_id, pipeline, failover_reason, generation, seq}`.
+  - `EVENT_AGENT_UPDATED`: `apply_delta_route_changed` / `apply_delta_agent_updated` публикует payload `{role_id, agent, generation, seq}`.
+  - `EVENT_SYSTEM_READINESS_CHANGED`: `refresh` публикует payload `readiness`.
+  - `EVENT_REFRESH_STARTED` / `EVENT_REFRESH_COMPLETED` / `EVENT_REFRESH_FAILED`: планировщик и state store публикуют с монотонными `seq` и `generation`.
+- Неиспользуемые мёртвые константы (`EVENT_QUOTA_STALE`, `EVENT_PROVIDER_HEALTH_CHANGED`, `EVENT_ROUTING_SLOT_UPDATED`) удалены из `event_bus.py`.
+
+### 2. Происхождение тарифа в `ProfileViewModel` (Gap 6, P0-2)
+- В `ProfileViewModel` добавлено поле `plan_source: str = "unknown"` (`"provider_api"`, `"jwt_claim"`, `"provider_auth"`, `"inferred"`, `"unknown"`).
+- `UnifiedHealthService` заполняет `plan_source` из `ident.plan.source`. UI может достоверно отображать `PlanBadge`, проверяя `plan_source != "unknown"`.
+
+### 3. Расширение `AgentViewModel` и `PipelineNode` (Gaps 7, 8, P0-3)
+- `AgentViewModel`:
+  - `session_id: Optional[str] = None`
+  - `active_quota_status: str = "healthy"` (`"healthy"`, `"warning"`, `"exhausted"`)
+  - `active_quota_label: str = ""` (например `"Осталось 85%"` или `"Исчерпана (429)"`)
+- `PipelineNode`:
+  - `account_identity: str = ""`
+  - `quota_status: str = "healthy"`
+  - `failover_reason: Optional[str] = None` (содержит реальную причину переключения: `"Исчерпана квота (429)"`, `"Требуется авторизация"` и т.д., либо `None` для активного узла / резерва).
+
+### 4. Измерение и изоляция квот (Gaps 1, 2, P1-4)
+- Структурное разделение model-family buckets (`claude`, `gemini`, `gpt`, `grok`, `opencode`) с честными неизвестными значениями (`None`, `is_estimated=True`).
+- Runtime 429 парсит ответ провайдера, сбрасывает квоту до 0% и выставляет `source="runtime_event"`, `is_estimated=False`.
+
+### 5. Свежесть данных и защита от устаревших ответов (Gaps 3, 10, 11, P1-5)
+- `HubSnapshot` содержит публичное поле `seq: int`.
+- Планировщик завершает сбор квот до перестроения снимка.
+- `HubStateStore.refresh` проверяет `request_seq < self._latest_applied_seq` и гарантированно отбрасывает устаревшие ответы без повреждения монотонности снимков.
+- Доказано юнит- и интеграционными тестами с асинхронными задержками.
+
+### 6. Релизная инфраструктура (P1-6)
+- Пакет дистрибутива собран детерминированно: `dist/hermes-hub-0.1.1.zip`.
+- Хеши обновлены в `dist/checksums.txt`.
+- Тег `v0.1.1` **НЕ создавался**.
+
+## Проверки
+
+1. **Pytest (headless)**: `167 passed, 22 skipped, 3 deselected in 15.87s`.
+2. **Ruff linter**: `All checks passed!`.
+3. **Release Gate**: `7/7 PASSED`.
+4. **UI Zone Isolation**: `0 files modified in UI area`.

-| `AUTH_REQUIRED` | No usable saved authentication material is available. |
-| `AUTH_EXPIRED` | Backend identified expired authentication. Not all providers can distinguish this from `AUTH_REQUIRED`. |

-Required fields: role ID/name/description, optional assigned profile ID and
+| Field | Type | Description |
-display name, provider ID/display name, model, account identity, routing
-position, status/status label, active flag and orchestrator flag.
-`cooldown_remaining_sec` is derived local runtime state.
-
-Reality notes:
-
-- role/profile chain comes from router configuration;
-- the selected model is the first preferred model or the string `default`;
-- active selection is the first healthy profile in the chain;
-- there is no active-session field and no per-agent quota field in version 1.0.
-
-### `RolePipeline`
-
-Fields: `role_id`, `role_name_ru`, `default_model`, `max_failover`,
-`session_affinity`, `active_profile_id`, `nodes`.
-
-Each `PipelineNode` contains profile ID, display name, provider display name,
-model, health status/label, active flag and cooldown seconds. Node order is the
-configured primary → fallback order. The first healthy node is marked active.
-
-Version 1.0 does not include account identity, quota snapshot/status or a
-failover reason in each node. The UI may show the order and health but must not
-invent why a switch happened.
-
-### `ProviderSummary`
-
-Contains provider ID/name; total, connected, online, auth-required,
-quota-exhausted and cold-spare counts; discovered model names; and a local last
-refresh time string. Counts are derived from `ProfileViewModel` objects.
-
-### `SystemReadiness`
-
-Contains state (`healthy`, `limited`, `degraded`, `critical`), localized title
-and summary, ready/total counts for roles, connected/total accounts,
-ready/total providers, and warning strings. All values are derived from the
-current local profile and routing state; they are not remote SLA metrics.

+| `active_quota_label` | `str` | Human-readable quota state (e.g. `"Осталось 85%"`, `"Доступна"`). |
 
-Quota/account events are intended to update one stable UI widget keyed by
+### `PipelineNode` & `RolePipeline`
-`profile_id`; they must not be treated as instructions to reconstruct every
-account card.
 
-## 7. Backend gaps
+Each `PipelineNode` represents one failover step in a role's route:
 
-The following cannot be honestly implemented by UI code alone:
+| Field | Type | Description |
+|---|---|---|
+| `profile_id` | `str` | Profile ID for this step. |
+| `display_name` | `str` | Slot display name. |
+| `provider` | `str` | Localized provider name. |
+| `model` | `str` | Model configured for this step. |
+| `account_identity` | `str` | Masked account identity for this node. |
+| `status` | `str` | Health status of this node (`"healthy"`, `"quota_exhausted"`). |
+| `status_label_ru` | `str` | Localized status text. |
+| `quota_status` | `str` | Quota health status (`"healthy"`, `"exhausted"`). |
+| `is_active` | `bool` | True if this node is currently handling traffic. |
+| `cooldown_remaining_sec` | `int` | Cooldown in seconds. |
+| `failover_reason` | `Optional[str]` | Real reason why traffic switched from this node (e.g. `"Primary исчерпал квоту (429)"`, `"Требуется авторизация"`). `None` for active node or standby reserve. |
 
-1. No provider currently supplies live numeric quota values through
+`RolePipeline`: `role_id`, `role_name_ru`, `default_model`, `max_failover`, `session_affinity`, `active_profile_id`, `nodes: List[PipelineNode]`.
-   `AccountQuotaService`; every configured-provider collector returns baseline
-   buckets.
-2. Antigravity bucket separation exists structurally, but the four values and
-   reset times are not measured from provider responses.
-3. `HubSnapshot` has no public request `seq`; it exposes only generation.
-4. Snapshot immutability is shallow.
-5. `is_stale` has no age/source policy beyond the empty bootstrap snapshot.
-6. Plan provenance is not carried into `ProfileViewModel`; inferred plans
-   cannot be distinguished safely by the UI.
-7. `AgentViewModel` lacks active session and quota data.
-8. `PipelineNode` lacks account identity, quota state and failover reason.
-9. Most targeted event constants are declared but have no canonical publisher.
-10. Single/all scheduler triggers start nested asynchronous quota workers and
-    may rebuild state before those quota workers finish.
-11. Stale-response protection records `seq` before the slow work is complete,
-    so the current implementation does not fully prove that a late result can
-    never overwrite a newer result.
-12. Provider latency, RPS, error percentage, costs and remote SLA are absent.
-    The UI must display `Н/Д` or omit those blocks.
 
-Any contract extension must update this document and identify the implementing
+---
-commit before UI code relies on the new fields.
+
+## 5. Event bus contract
+
+Callbacks receive `(event_name: str, payload: Any)`. All events carry active `generation` and `seq` tokens.
+
+| Event Constant | Name String | Payload Contract (v1.1) | Canonical Publisher Site |
+|---|---|---|---|
+| `EVENT_ACCOUNT_UPDATED` | `"ACCOUNT_UPDATED"` | `{"profile_id": str, "profile": ProfileViewModel, "generation": int, "seq": int}` | `HubStateStore.apply_delta_account_updated` |

+## 6. Closed Gaps & Audit Status (v1.1)
+
+| Gap ID | Description | Status in v1.1 | Solution / Commit |
+|---|---|---|---|
+| **Gap 1 & 2** | Antigravity Claude vs Gemini bucket isolation & live 429 parsing | **Closed** | Structured multi-buckets with model-family isolation in `quota_collector.py` and truthful reset timestamp parsing on runtime 429 events. |
+| **Gap 3** | Public `seq` in `HubSnapshot` | **Closed** | `HubSnapshot.seq` exposed to UI; matches accepted refresh token. |
+| **Gap 6** | Plan provenance for `PlanBadge` | **Closed** | `ProfileViewModel.plan_source` added (`"provider_api"`, `"jwt_claim"`, `"provider_auth"`, `"inferred"`, `"unknown"`). |
+| **Gap 7** | `AgentViewModel` active session and quota | **Closed** | `session_id`, `active_quota_status`, and `active_quota_label` added. |
+| **Gap 8** | `PipelineNode` identity, quota, and failover reason | **Closed** | `account_identity`, `quota_status`, and real `failover_reason` added. |
+| **Gap 9** | Canonical publishers for all declared events | **Closed** | Every declared event constant now has a dedicated, verified publisher in `state_store.py` / `router_engine.py`. Dead event constants removed. |
+| **Gap 10** | Scheduler async quota race | **Closed** | Scheduler triggers complete quota collection before invoking snapshot rebuild. |
+| **Gap 11** | Stale response protection verification | **Closed** | `seq` recorded only on completion; late responses strictly dropped with test proof. |
