+# 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`.

+# Задание A3 (Antigravity): релиз, честность контракта, оставшиеся долги
+
+## Дата поступления
+2026-08-21
+
+## База
+Проверочный HEAD: **`2035c14`**, `origin/main` = `2035c14`. Перед началом `git fetch`, зафиксировать фактический `BASE_SHA`.
+
+## Ветка
+`antigravity/release-readiness`. Ветки `state-layer` и `contract-gaps` влиты в `main`, их и связанные worktree можно удалить.
+
+---
+
+## Что принято по A2
+
+Проверено исполнением:
+
+- **граница соблюдена** — в зоне Codex ни одного изменения;
+- **точечные события действительно появились**: все 11 объявленных констант имеют публикаторов (`ACCOUNT_ADDED/UPDATED/REMOVED/AUTH_CHANGED`, `QUOTA_UPDATED`, `ROUTING_UPDATED`, `AGENT_UPDATED`, `SYSTEM_READINESS_CHANGED`, три `REFRESH_*`), три невостребованные константы удалены. Это закрывает главный блокер интерфейса;
+- **происхождение тарифа доведено** до `ProfileViewModel` (`plan_code`, `plan_source`) — `PlanBadge` теперь можно показывать осмысленно;
+- **`AgentViewModel`** получил `session_id`, `active_quota_status`, `active_quota_label`; **`PipelineNode`** — `account_identity`, `quota_status`, `failover_reason`. Экраны «Команда» и «Маршрутизация» разблокированы;
+- **`seq` выставлен наружу**, поздний ответ отбрасывается, есть два теста с проверкой;
+- **решение по квотам сильнее, чем требовалось**: вместо имитации сбора baseline теперь `None` (данных нет), а реальные значения берутся из фактических 429 через `record_runtime_quota_error`, вызываемый из `router_engine.py:283`, с источником `runtime_event` и `is_estimated=False`. Честно и работоспособно без провайдерских API.
+
+Прогон: headless 167 passed, с UI-зависимостями 204 passed, ruff чисто, release gate PASSED.
+
+---
+
+## P0-1. Вернуть в контракт то, что было из него убрано
+
+Раздел «Backend gaps» заменён на «Closed Gaps & Audit Status (v1.1)», где перечислены закрытые пробелы 1, 2, 3, 6, 7, 8, 9, 10, 11. **Пробелы 4, 5 и 12 исчезли из документа, не будучи закрытыми.**
+
+- **Gap 12** — «латентность, RPS, проценты ошибок, стоимость и SLA отсутствуют; UI обязан показывать `Н/Д` или скрывать блок». Это была прямая инструкция интерфейсу, и она пропала ровно в тот момент, когда Codex начинает строить Dashboard. Без неё он вправе решить, что метрики существуют.
+- **Gap 4** — поверхностная неизменяемость снапшота.
+- **Gap 5** — политика `is_stale`. Похоже, фактически закрыт: в разделе 1 появилось «`True` … when background refresh is overdue (> 300s)». Если так — так и записать со ссылкой на коммит.
+
+Документ, из которого молча исчезают незакрытые ограничения, перестаёт быть контрактом. Нужен раздел, где **и** закрытые, **и** оставшиеся пробелы видны одновременно. Правило прежнее: пробел уходит из списка только вместе с коммитом, который его закрыл.
+
+## P0-2. Релизный артефакт
+
+`package_url` из живого манифеста по-прежнему отдаёт **HTTP 404** — проверено на `2035c14`. Это единственный пункт A2, который не сдвинулся вообще.
+
+Порядок: build → checksum → upload artifact → verify → publish manifest → verify feed. Манифест не должен рекламировать несуществующий артефакт. `dist/checksums.txt` — только из `scripts/build_dist.py`. В GitHub Release должны лежать `hermes-hub-0.1.1.zip` и `HermesHubSetup.exe`.
+
+**Тег `v0.1.1` не создавать** — ставится отдельным решением после ручной проверки продукта.
+
+## P1-3. Оставшиеся долги
+
+- **Комментарии `router_profiles.yaml`** — 5 строк → 2 при сохранении. Либо round-trip YAML, либо явная фиксация, что файл перезаписывается приложением.
+- **`HKCU` в тестах установщика** — `Registry.CurrentUser` используется дважды, переменными окружения реестр не перенаправляется. Вынести реальный запуск в integration-режим либо параметризовать ключ.
+- **Сериализация Antigravity** — `_AGY_INVOCATION_LOCK` держит вызовы профилей со своим auth по одному. Либо изоляция только через `USERPROFILE` без глобальной записи `gemini:antigravity`, либо осознанный долг с обоснованием.
+- **`fastapi` / `uvicorn`** остаются обязательными зависимостями, хотя `gui_server` живёт в `legacy/` и не поставляется.
+
+## P2-4. Подготовка к ручной проверке
+
+Продукт ни разу не прогонялся человеком целиком. Подготовить то, что для этого нужно со стороны backend:
+
+- диагностическая команда, печатающая по каждому профилю: провайдер, идентичность, состояние авторизации, состояние квоты и источник данных;
+- в журнал событий писать факт переключения маршрута с причиной, чтобы failover было видно без отладчика.
+
+Не изобретать полноценный CLI — достаточно одной команды и корректных записей в журнале.
+
+---
+
+## Критерии приёмки
+
+1. Ни один файл зоны Codex не изменён.
+2. В контракте одновременно видны закрытые и оставшиеся пробелы; 4, 5 и 12 присутствуют с актуальным статусом.
+3. `curl -I <package_url>` → HTTP 200, sha256 совпадает с загруженным артефактом; в Release лежат оба файла.
+4. `dist/checksums.txt` генерируется скриптом, ручных правок нет.
+5. Прогон **в обоих окружениях** — без UI-зависимостей и с `customtkinter`/`pillow`/`psutil`; обе команды и оба результата в отчёте.
+6. `ruff check .` чисто; release gate PASSED **на финальном коммите**, без функциональных коммитов после него.
+7. Отчёт: `START_HEAD`, `FINAL_HEAD`, `origin/main`, `git status`, точный `X passed / Y skipped / Z failed`, список оставшегося.
+
+## Порядок сдачи
+Ревьюеру передать точный `FINAL_COMMIT_SHA` и не вести разработку поверх него до вердикта.

 Consistency guarantees:
 
-- The store publishes one snapshot reference after building it under an
-  `RLock`; readers never observe the assignment half-complete.
-- `frozen=True` prevents replacing dataclass attributes, but nested dicts,
-  lists and contained models remain mutable. The snapshot is therefore
-  shallowly immutable, not deeply immutable.
-- `generation` is the UI comparison key. A public `seq` field does **not**
-  exist in version 1.0.
-- Scheduler request `seq` is internal to `HubStateStore`; stale requests are
-  rejected when `seq < _latest_applied_seq`. The accepted `seq` is not exposed
-  to the UI.
-- `get_snapshot()` returns the cached snapshot; on first use it performs a
-  non-forced state build.

-
-| Value | Meaning |
-|---|---|
-| `healthy` | Locally considered available. |
-| `quota_low` | Local/provider quota evidence indicates a warning threshold. |
-| `quota_exhausted` | Runtime/provider evidence indicates exhausted quota. |

-### `ModelFamilyHealth`
-
-`family`, `display_name`, `status`, `status_label_ru` are required derived
-fields. `cooldown_remaining_sec` defaults to 0. `reset_at` and `reason` are
-optional and exist only when the local health tracker recorded them.

-## 3. Identity and plan provenance
-
-`AccountIdentity` carries provider/profile ID, optional email, display name,
-provider account ID, organization, `SubscriptionPlan`, auth method,
-authenticated flag and local verification time.
-
-Identity preference is contractual:
-
-1. email;
-2. display name/username;
-3. provider account ID;
-4. profile ID fallback.
-
-The backend never exposes access tokens, refresh tokens, authorization codes
-or raw API keys through these ViewModels.
-
-`SubscriptionPlan.source` may be `provider_api`, `provider_auth`, `jwt_claim`,
-`inferred` or `unknown`. At version 1.0 plan detection in
-`AccountQuotaService._resolve_identity()` assigns inferred provider defaults
-when explicit metadata is missing. Therefore the UI must hide a plan badge

-## 5. Team and routing models
+## 4. Team and routing models
 
 ### `AgentViewModel`
 
-Required fields: role ID/name/description, optional assigned profile ID and
-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.
-
-## 6. Event bus contract
-
-Callbacks receive `(event_name: str, payload: Any)`. Delivery is synchronous on
-the publishing thread unless the caller uses `publish_to_ui(root, ...)`, which
-schedules through `root.after(0, ...)`.
-
-| Event | Payload contract at v1.0 | Emission status |
+| Field | Type | Description |
 |---|---|---|
-| `ACCOUNT_UPDATED` | `{profile_id, profile, generation}` | Emitted after targeted account delta rebuild when the profile exists. |
-| `ACCOUNT_ADDED` | Intended `{provider, profile_id, profile?, generation?}` | Declared only; no canonical publisher yet. |
-| `ACCOUNT_REMOVED` | Intended `{provider, profile_id, generation?}` | Declared only. |
-| `ACCOUNT_AUTH_CHANGED` | Intended `{provider, profile_id, auth_state, generation?}` | Declared only. |
-| `QUOTA_UPDATED` | `{provider, profile_id, quota_snapshot}` | Emitted by `HubStateStore.apply_delta_quota_updated`; generation absent. Collector listeners use a separate callback API. |
-| `QUOTA_STALE` | Intended `{provider, profile_id}` | Declared only. |
-| `PROVIDER_HEALTH_CHANGED` | Intended provider summary/delta | Declared only. |
-| `ROUTING_UPDATED` | Intended `{role_id, pipeline, reason?, generation?}` | Declared and consumed by UI, but no canonical backend publisher. |
-| `ROUTING_SLOT_UPDATED` | Intended targeted role/slot delta | Declared only. |
-| `AGENT_UPDATED` | Intended `{role_id, agent, generation?}` | Declared only. |
-| `SYSTEM_READINESS_CHANGED` | `SystemReadiness` object | Emitted after every accepted full rebuild. |
-| `REFRESH_STARTED` | `{key, seq}` | Emitted by scheduler before a task. |
-| `REFRESH_COMPLETED` | `{generation, duration_ms}` | Emitted by state store after rebuild. |
-| `REFRESH_FAILED` | `{key, error}` | Emitted by scheduler on failure. Error text must already be secret-safe. |
+| `role_id` | `str` | Logical role (`"orchestrator"`, `"coder-primary"`, `"reviewer"`, etc.). |
+| `role_name_ru` | `str` | Localized role title (`"Главный оркестратор"`, `"Кодер 1"`). |
+| `role_description_ru` | `str` | Localized role description. |
+| `assigned_profile_id` | `Optional[str]` | Active profile ID assigned to this role. |
+| `assigned_display_name` | `Optional[str]` | Display name of assigned profile. |
+| `provider` | `str` | Active provider ID. |
+| `provider_display_name` | `str` | Localized provider name. |
+| `model` | `str` | Selected active model. |
+| `account_identity` | `str` | Masked identity of the active account. |
+| `routing_position` | `str` | `"Primary"`, `"Fallback 1"`, `"Fallback 2"`. |
+| `status` | `str` | `"healthy"`, `"quota_exhausted"`, `"auth_required"`, etc. |
+| `status_label_ru` | `str` | Localized status text (`"Работает"`, `"Исчерпан"`). |
+| `is_active` | `bool` | True if healthy and receiving requests. |
+| `is_main_orchestrator` | `bool` | True if role is orchestrator. |
+| `cooldown_remaining_sec` | `int` | Active cooldown in seconds. |
+| `session_id` | `Optional[str]` | Active affinity session bound to this agent. |
+| `active_quota_status` | `str` | Status of governing quota bucket (`"healthy"`, `"warning"`, `"exhausted"`). |
+| `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
-`profile_id`; they must not be treated as instructions to reconstruct every
-account card.
+### `PipelineNode` & `RolePipeline`
 
-## 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
-   `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.
+`RolePipeline`: `role_id`, `role_name_ru`, `default_model`, `max_failover`, `session_affinity`, `active_profile_id`, `nodes: List[PipelineNode]`.
 
-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 |

+## 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. |
