-Быстрый запуск TUI-проверки:
+### Операционный workflow (CLI/API/TUI)
+
+#### 1) Headless flow через CLI (рекомендуется для CI/CD)
+
+```bash
+cd backend
+
+# 1. Регистрация кандидата
+.venv/bin/python3 -m src.scripts.clean_release_cli candidate-register \
+  --candidate-id 2026.03.09-rc1 \
+  --version 1.0.0 \
+  --source-snapshot-ref git:release/2026.03.09-rc1 \
+  --created-by release-operator
+
+# 2. Импорт артефактов
+.venv/bin/python3 -m src.scripts.clean_release_cli artifact-import \
+  --candidate-id 2026.03.09-rc1 \
+  --artifact-id artifact-001 \
+  --path backend/dist/package.tar.gz \
+  --sha256 deadbeef \
+  --size 1024
+
+# 3. Сборка манифеста
+.venv/bin/python3 -m src.scripts.clean_release_cli manifest-build \
+  --candidate-id 2026.03.09-rc1 \
+  --created-by release-operator
+
+# 4. Запуск compliance
+.venv/bin/python3 -m src.scripts.clean_release_cli compliance-run \
+  --candidate-id 2026.03.09-rc1 \
+  --actor release-operator
+```
+
+#### 2) API flow (автоматизация через сервисы)
+
+- V2 candidate/artifact/manifest API:
+  - `POST /api/clean-release/candidates`
+  - `POST /api/clean-release/candidates/{candidate_id}/artifacts`
+  - `POST /api/clean-release/candidates/{candidate_id}/manifests`
+  - `GET /api/clean-release/candidates/{candidate_id}/overview`
+- Legacy compatibility API (оставлены для миграции клиентов):
+  - `POST /api/clean-release/candidates/prepare`
+  - `POST /api/clean-release/checks`
+  - `GET /api/clean-release/checks/{check_run_id}`
+
+#### 3) TUI flow (тонкий клиент поверх facade)
 
 ```bash
 cd /home/busya/dev/ss-tools
-./backend/.venv/bin/python3 -m backend.src.scripts.clean_release_tui
+./run_clean_tui.sh 2026.03.09-rc1
 ```
 
+Горячие клавиши:
+- `F5`: Run Compliance
+- `F6`: Build Manifest
+- `F7`: Reset Draft
+- `F8`: Approve
+- `F9`: Publish
+- `F10`: Refresh Overview
+
+Важно: TUI требует валидный TTY. Без TTY запуск отклоняется с инструкцией использовать CLI/API.

+- `F5`: Run Compliance
+- `F6`: Build Manifest
+- `F7`: Reset Draft
+- `F8`: Approve
+- `F9`: Publish
+- `F10`: Refresh Overview
+
 Ожидаемый flow:
 1. Выбрать `candidate_id`.
 2. Подтвердить `profile=enterprise-clean`.
-3. Запустить проверку (F5).
-4. Дождаться терминального статуса:
-   - `COMPLIANT` — кандидат готов к следующему этапу выпуска;
-   - `BLOCKED` — выпуск запрещён до устранения нарушений.
+3. Выполнить `F6` (если манифест отсутствует).
+4. Выполнить `F5` для compliance.
+5. При `COMPLIANT` — перейти к `F8` и `F9`.
+6. При `BLOCKED` — устранить нарушения и повторить `F5`.
 
 По умолчанию `run_clean_tui.sh` запускает TUI в `real` режиме (`CLEAN_TUI_MODE=real`) без инъекции демонстрационных нарушений.
+Важно: TUI запускается только в интерактивном TTY; для headless-среды используйте CLI/API.

-# Git Settings & Service Test Coverage Walkthrough
-
-## 1. Overview and Objectives
-The objective of this task was to thoroughly review and implement testing for the Git Integration capabilities of SS-Tools. This included verifying the Test Coverage of `git.py`, `gitService.js`, and the `GitSettingsPage` component (`+page.svelte`).
-
-The workflow followed the `@TEST_DATA` and `@UX_` contract rules mandated by the `GRACE-Poly` technical standards to guarantee semantic correctness.
-
-## 2. Test Coverage Matrix
-
-| Component | File Path | Status | Coverage Focus |
-|-----------|-----------|--------|----------------|
-| **Git API (Backend)** | [`git.py`](file:///home/busya/dev/ss-tools/backend/src/api/routes/git.py) | ✅ Fully Tested | CRUD configuration operations (`get_git_configs`, `create_git_config`, `update_git_config`, `delete_git_config`), connection `test_git_config`, Repository Initialization/Deletion, Edge Cases (e.g., config not found, missing permissions, repo already exists). Added `test_git_api.py`. |
-| **Git Service (Frontend)** | [`gitService.js`](file:///home/busya/dev/ss-tools/frontend/src/services/gitService.js) | ✅ Fully Tested | All method branches invoking `requestApi` are mocked and verified for correct endpoint URL formatting and body payload transmission (Coverage for 26 endpoint cases). Added `gitService.test.js`. |
-| **Git Settings (Frontend UX)** | [`+page.svelte`](file:///home/busya/dev/ss-tools/frontend/src/routes/settings/git/+page.svelte) | ✅ Fully Tested | `@UX_STATE` (Initial Load, Empty State, Form Editing, Skeleton rendering), `@UX_FEEDBACK` (Toast indicators upon successful save, error reporting on fetch failures, connection validations, delete confirmations) using Vitest and testing-library/svelte. Added `git_settings_page.ux.test.js`. |
-
-## 3. Notable Fixes & Iterations
-
-During script execution and iteration, the following remediation tasks were performed:
-
-*   **Pydantic Compatibility (`git.py`)**: `GitServerConfigCreate` extended `GitServerConfigBase` with an optional `config_id` argument (intended for UI testing requests without transmitting full PAT credentials). However, the instantiation loop dynamically dumped all kwargs into `GitServerConfig`. Fixed via restricting payload parameters (`config.dict(exclude={"config_id"})`).
-*   **Vitest Import Paths (`git_settings_page.ux.test.js`)**: Corrected deeply nested relative paths pointing to `/services/gitService` within the `vi.mock` configurations mapping to correct directory tree levels (`../../../../services/gitService`).
-*   **Pytest DbMock Filter Masking (`test_git_api.py`)**: Repositories creation via SQLAlchemy's `.first()` mock incorrectly returned existing objects when filtering by distinct models since the mock lacked typing recognition. Added explicit isinstance type filtering to cleanly isolate models instantiated in tests.
-
-## 4. Verification Execution
-
-We launched local verifications across the UI frameworks to guarantee functionality runs consistently:
-
-### Backend FastApi Routes
-```bash
-> cd backend && .venv/bin/python3 -m pytest src/api/routes/__tests__/test_git_api.py -v
-================== short test summary info ===================
-11 passed, 4235 warnings in 1.57s
-```
-
-### Frontend Vitest Configurations
-```bash
-> cd frontend && npx vitest run src/services/__tests__/gitService.test.js src/routes/settings/git/__tests__/git_settings_page.ux.test.js
-✓ src/routes/settings/git/__tests__/git_settings_page.ux.test.js (6 tests) 174ms
-✓ src/services/__tests__/gitService.test.js (26 tests) 17ms
-
-Test Files  2 passed (2)
-     Tests  32 passed (32)
-  Duration  1.55s 
-```
-
-All new checks completed perfectly and emit standard Molecular Topology logging markers such as `[Coherence:OK]` internally.

+# Specification Quality Checklist: Clean Release Compliance Subsystem Redesign
+
+**Purpose**: Validate specification completeness and quality before proceeding to planning  
+**Created**: 2026-03-09  
+**Feature**: [spec.md](../spec.md)
+
+## Content Quality
+
+- [x] No implementation details (languages, frameworks, file structure) drive the requirements
+- [x] Focused on operator value, governance, auditability, and release workflow outcomes
+- [x] Written for product/release stakeholders, not only for implementers
+- [x] All mandatory sections completed
+
+## Requirement Completeness
+
+- [x] No [NEEDS CLARIFICATION] markers remain
+- [x] Requirements are testable and unambiguous
+- [x] Success criteria are measurable
+- [x] Success criteria are technology-agnostic
+- [x] All acceptance scenarios are defined
+- [x] Edge cases are identified
+- [x] Scope is clearly bounded
+- [x] Dependencies and assumptions identified
+
+## Feature Readiness
+
+- [x] All functional requirements have clear acceptance intent
+- [x] User scenarios cover primary lifecycle flows
+- [x] Feature meets measurable outcomes defined in Success Criteria
+- [x] No blocking ambiguity remains for `/speckit.plan`
+- [x] Specification is ready for `/speckit.plan` and `/speckit.tasks`
+
+## Notes
+
+- Architectural direction is intentional because the feature itself is a subsystem redesign rather than a small end-user capability.
+- Trust model, lifecycle invariants, and immutable evidence were kept at the requirement level because they are the product value of this redesign.

+# CLI Contract: Clean Release Compliance Subsystem Redesign
+
+## Command Groups
+
+### Candidate
+
+```bash
+clean-release candidate register --candidate-id <id> --version <version> --source-snapshot <ref> [--build-id <id>] [--provenance-ref <ref>] [--actor <actor>]
+clean-release candidate import-artifacts --candidate-id <id> --input <artifacts.json> [--actor <actor>]
+clean-release candidate show --candidate-id <id> [--json]
+clean-release candidate list [--json]
+```
+
+### Manifest
+
+```bash
+clean-release manifest build --candidate-id <id> [--actor <actor>] [--json]
+clean-release manifest show --manifest-id <id> [--json]
+clean-release manifest list --candidate-id <id> [--json]
+```
+
+### Compliance
+
+```bash
+clean-release compliance run --candidate-id <id> [--manifest-id <manifest_id>] [--actor <actor>] [--json]
+clean-release compliance status --run-id <run_id> [--json]
+clean-release compliance report --run-id <run_id> [--json]
+clean-release compliance violations --run-id <run_id> [--json]
+```
+
+### Release
+
+```bash
+clean-release release approve --candidate-id <id> --report-id <report_id> --actor <actor> [--comment <text>] [--json]
+clean-release release reject --candidate-id <id> --report-id <report_id> --actor <actor> [--comment <text>] [--json]
+clean-release release publish --candidate-id <id> --report-id <report_id> --channel <channel> --actor <actor> [--json]
+clean-release release revoke --publication-id <publication_id> --actor <actor> --reason <text> [--json]
+```
+
+### Demo
+
+```bash
+clean-release demo seed [--profile <name>] [--json]
+clean-release demo reset [--json]
+```
+
+## Output Rules
+
+- Default mode prints concise operator-friendly summaries.
+- `--json` prints machine-readable DTO payloads.
+- Errors print machine-readable codes and short text to stderr.
+- Compliance run creation returns `run_id` and `task_id` immediately.
+- If `--manifest-id` is omitted, CLI uses the latest manifest for the candidate or returns invalid input when no manifest exists.
+
+## Actor Mapping Rule
+
+- CLI always accepts external actor context as `--actor`.
+- Interface adapters map `--actor` to internal domain fields by action type:
+  - candidate register -> `created_by`
+  - manifest build -> `created_by`
+  - compliance run -> `requested_by`
+  - release approve/reject -> `decided_by`
+  - release publish -> `published_by`
+  - release revoke -> revocation actor field in command payload or audit event
+- This mapping is deterministic and hidden from operators; CLI does not expose multiple actor flag names for different commands.
+
+## Exit Codes
+
+- `0`: Passed / successful mutation / successful read.
+- `1`: Business blocked (`BLOCKED`, forbidden publish/approve because of valid business rule).
+- `2`: Invalid input (`candidate not found`, `manifest missing`, malformed request).
+- `3`: System error (`policy store unavailable`, persistence failure, unexpected exception).
+
+## CLI Behavior Constraints
+
+- Business actions are explicit CLI arguments, not env-driven side effects.
+- CLI supports headless operation and never requires curses/TTY.
+- CLI does not synthesize policy or registry values locally.

+## TUI Thin Client Contract
+
+<!-- [DEF:CleanReleaseTuiApp:Component] -->
+/**
+ * @TIER: CRITICAL
+ * @SEMANTICS: [tui, thin_client, operator, live_status]
+ * @PURPOSE: Render current clean release overview and trigger facade actions without owning business logic.
+ * @LAYER: UI
+ * @RELATION: DEPENDS_ON -> [DEF:CleanReleaseFacadeModule]
+ * @INVARIANT: TUI never constructs policy, registry, manifest or fake run state locally.
+ * @PRE: Running terminal has a valid TTY; candidate context is resolvable.
+ * @POST: Operator can build manifest, run compliance, approve and publish only when transitions are valid.
+ * @UX_STATE: Loading -> Candidate overview is refreshing and action keys are temporarily disabled.
+ * @UX_STATE: Ready -> Candidate summary, latest manifest, latest run and latest report are visible.
+ * @UX_STATE: Running -> Current stage and task/run progress are visible from real task events.
+ * @UX_STATE: Blocked -> Violations list and blocking reason are visually dominant; approve/publish disabled.
+ * @UX_STATE: Error -> Failure reason is explicit and no hidden retry occurs.
+ * @UX_FEEDBACK: F5/F6/F8/F9 actions show immediate command acknowledgment and then refresh from persisted DTOs.
+ * @UX_RECOVERY: Operator can refresh, inspect violations, rebuild manifest or rerun compliance after fixing candidate inputs.
+ * @TEST_CONTRACT: CleanReleaseTuiApp -> {Input: keypress + facade DTOs, Output: rendered state + triggered facade action}
+ * @TEST_FIXTURE: tui_ready_candidate -> INLINE_JSON {"candidate_id":"2026.03.09-rc1","status":"MANIFEST_BUILT"}
+ * @TEST_EDGE: no_tty_environment -> refuse startup and redirect to CLI

+
+## Contract Usage Simulation (Key Scenario)
+
+Scenario traced: operator runs compliance from TUI after building a manifest.
+
+1. `CleanReleaseTuiApp` requests `CandidateOverviewDTO` from `CleanReleaseFacadeModule`.
+2. Operator presses `F5`.
+3. `CleanReleaseFacadeModule` calls `ComplianceExecutionServiceModule.request_run(...)`.
+4. `PolicyResolutionServiceModule` resolves trusted snapshots.
+5. `ComplianceExecutionServiceModule` creates a run, binds it to `TaskManagerModule`, returns `run_id` and `task_id` immediately.
+6. `StagePipelineModule` emits ordered stage results and violations.
+7. `AuditServiceModule` persists append-only events.
+8. `ReportRepositoryModule` persists immutable final report on terminal completion.
+9. TUI refreshes and renders persisted DTOs without local recomputation.
+
+Continuity check: no interface mismatch found across facade, services and thin-client rendering path.

+## 15. Relationships
+
+- `ReleaseCandidate 1 -> N CandidateArtifact`
+- `ReleaseCandidate 1 -> N DistributionManifest`
+- `ReleaseCandidate 1 -> N ComplianceRun`
+- `ComplianceRun 1 -> N ComplianceStageRun`
+- `ComplianceRun 1 -> N ComplianceViolation`
+- `ComplianceRun 1 -> 1 ComplianceReport` (for terminal runs that produce a report)
+- `ComplianceReport 1 -> N ApprovalDecision` (history allowed, latest valid decision governs)
+- `ReleaseCandidate 1 -> N PublicationRecord`
+- `CleanPolicySnapshot 1 -> 1 SourceRegistrySnapshot`
+
+## 16. Invariants
+
+- Policy, registry, manifest, report, approval and publication snapshots are immutable after creation.
+- Real mode compliance evidence is append-only and not user-deletable.
+- `APPROVED` requires a valid `PASSED` report.
+- `PUBLISHED` requires a valid approval.
+- `REJECTED` is modeled as an immutable latest approval decision, not as a separate candidate lifecycle state.
+- Demo namespace never shares identifiers or historical storage with real mode.
+
+## 17. Scale Assumptions
+
+- Candidate histories may accumulate multiple manifests and multiple compliance runs per release.
+- A single run may produce many violations and stage details, so read models should not require loading all artifacts for each overview request.
+- Most interface reads use latest-only summary views, while audit and compliance screens require full history retrieval.

+# Implementation Plan: Clean Release Compliance Subsystem Redesign
+
+**Branch**: `025-clean-release-compliance` | **Date**: 2026-03-09 | **Spec**: [spec.md](./spec.md)  
+**Input**: Feature specification from [`/specs/025-clean-release-compliance/spec.md`](./spec.md)
+
+## Summary
+
+Перевести текущую clean-release подсистему из TUI-first orchestration в API/CLI-first release/compliance subsystem с четырьмя жёстко разделёнными слоями:
+1. domain model для candidate, manifest, policy snapshot, run, report, approval, publication;
+2. application services для candidate preparation, manifest build, policy resolution, compliance execution, approval, publication и audit;
+3. infrastructure layer для repositories, trusted policy access, artifact storage, audit storage и task execution;
+4. thin interfaces для CLI, TUI, REST API и будущего Web UI.
+
+Ключевой результат: TUI перестаёт быть местом, где живёт release logic. Все критические действия выполняются единым facade/application layer, compliance evidence становится immutable/append-only, а long-running runs интегрируются с существующим TaskManager.
+
+## Technical Context
+
+**Language/Version**: Python 3.9+ for backend services, CLI, API and TUI  
+**Primary Dependencies**: FastAPI, Pydantic models, existing `TaskManager`, existing reports service patterns, repository adapters, curses-compatible TUI runtime  
+**Storage**: PostgreSQL for metadata and snapshots, filesystem/object storage for artifacts and persisted reports, trusted policy/registry store (read-only source)  
+**Testing**: pytest unit/integration/contract suites, CLI smoke tests, API contract checks, TUI facade smoke tests  
+**Target Platform**: Linux server and CI pipeline in enterprise environment  
+**Project Type**: Backend web service with operational CLI/TUI interfaces  
+**Performance Goals**:
+- request to start compliance returns run/task identifiers in <= 2 seconds for a typical candidate;
+- candidate overview and status reads return in <= 1 second for the latest candidate history;
+- final report becomes available immediately after terminal run finalization.
+**Constraints**:
+- policy and registry are trusted read-only inputs, never sourced from TUI/env bootstrap payloads;
+- trusted policy store location, active profile selection, mode switching and storage wiring must be resolved through existing `ConfigManager` access patterns rather than ad hoc constants or raw env reads;
+- long-running compliance execution must use `TaskManager` and non-blocking API behavior;
+- real mode audit history and compliance evidence are append-only;
+- TUI must remain usable for operators but cannot contain hidden business logic;
+- migration should be incremental because existing code already exposes `clean_release` routes, services and a TUI entrypoint.
+**Scale/Scope**:
+- tens to hundreds of release candidates per month;
+- each candidate may include thousands of artifacts;
+- multiple compliance runs and reports may exist for one candidate;
+- redesign touches backend domain, API, CLI, TUI and operational documentation.
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+1. **Semantic Protocol Compliance**: All new modules in this plan are defined via explicit contracts in [`contracts/modules.md`](./contracts/modules.md). Code implementation must follow `[DEF]`, `@PRE`, `@POST`, testing tags and closing anchors. Status: PASS.
+2. **Modular Architecture**: Business logic is moved into `backend/src/services/clean_release/` services and repository adapters; interfaces remain thin. Status: PASS.
+3. **Independent Testability**: Spec defines independent tests for each user story; tasks will preserve isolated validation paths. Status: PASS.
+4. **Asynchronous Execution**: Compliance run execution is explicitly mapped to `TaskManager`, and API launch endpoints are non-blocking. Status: PASS.
+5. **Config Discipline**: Policy and registry sources are moved out of ad hoc env/bootstrap input into trusted resolution services. Status: PASS with migration note that existing env-based flows must be deprecated, not silently retained.
+6. **Centralized Config**: Trusted store endpoints, mode/profile selection and storage wiring must reuse `ConfigManager` / `get_config_manager()` patterns required by repository constitution. Status: PASS with explicit implementation follow-up in foundational tasks.

+
+**Structure Decision**: Сохраняем существующую backend-centric структуру проекта и расширяем текущий пакет `backend/src/services/clean_release/` вместо выделения нового top-level приложения. Это уменьшает migration risk и позволяет поэтапно заменить текущие `preparation_service`, `manifest_builder`, `compliance_orchestrator` и `clean_release_tui.py` на фасадную архитектуру.
+
+## Phase 0 Research Scope
+
+Research resolved the main architectural questions and produced decisions in [`research.md`](./research.md):
+- trust model for policy and registry;
+- immutable snapshot strategy;
+- lifecycle/state machine design;
+- TaskManager integration strategy;
+- interface split between CLI/API/TUI;
+- repository decomposition and migration approach;
+- demo mode isolation.
+
+## Phase 1 Design Outputs
+
+Phase 1 produces:
+- [`data-model.md`](./data-model.md) with canonical entities, states and relationships;
+- [`contracts/modules.md`](./contracts/modules.md) with module-level contracts for new services and interfaces;
+- [`contracts/clean-release-api.openapi.yaml`](./contracts/clean-release-api.openapi.yaml) and [`contracts/cli.md`](./contracts/cli.md) for programmatic interfaces;
+- [`ux_reference.md`](./ux_reference.md) for thin-client TUI/CLI behavior;
+- [`quickstart.md`](./quickstart.md) for implementation and validation scenarios.
+
+## Post-Design Constitution Re-Check
+
+1. **No interface-owned business logic**: Preserved by facade + application services. PASS.
+2. **Async long-running work**: Preserved by explicit `ComplianceExecutionService -> TaskManager` mapping. PASS.
+3. **Independent testability**: Preserved via user-story tasks and dedicated contract tests. PASS.
+4. **Config discipline and trust boundaries**: Preserved by read-only policy resolution service and immutable snapshots. PASS.
+
+## Implementation Risks To Control
+
+- Existing `clean_release_tui.py` currently owns preparation/build/run logic and must be thinned without breaking operator workflow.
+- Existing repository and model naming may conflict with the redesigned entity boundaries; migration shims may be needed.
+- Existing `/api/clean-release/checks*` endpoints may require compatibility strategy while introducing candidate/manifest/run-oriented endpoints.
+- Existing `.clean-release.yaml` driven flow from `023-clean-repo-enterprise` conflicts with the new trusted policy-store model and must be deliberately deprecated or scoped.
+
+## Complexity Tracking
+
+| Violation | Why Needed | Simpler Alternative Rejected Because |
+|-----------|------------|-------------------------------------|
+| Multiple service modules instead of one orchestrator | Trust boundaries, immutability and lifecycle rules need explicit ownership | One orchestrator keeps the current blending of UI, policy, execution and persistence concerns |
+| Separate repositories/facade layer | Needed for append-only evidence and independent interfaces | Single universal repository would keep ambiguous ownership and weak contracts |
+| TaskManager integration for runs | Constitution requires async lifecycle and observability | Synchronous API/TUI execution would violate non-blocking execution requirements |

+Use this package to implement and validate the redesigned clean release subsystem defined in:
+- Spec: [`spec.md`](specs/025-clean-release-compliance/spec.md)
+- Plan: [`plan.md`](specs/025-clean-release-compliance/plan.md)
+- UX reference: [`ux_reference.md`](specs/025-clean-release-compliance/ux_reference.md)
+- Data model: [`data-model.md`](specs/025-clean-release-compliance/data-model.md)
+- Contracts: [`contracts/modules.md`](specs/025-clean-release-compliance/contracts/modules.md), [`contracts/clean-release-api.openapi.yaml`](specs/025-clean-release-compliance/contracts/clean-release-api.openapi.yaml), [`contracts/cli.md`](specs/025-clean-release-compliance/contracts/cli.md)
+
+## 1) Backend implementation flow
+
+1. Introduce canonical lifecycle/domain entities and state machine guards.
+2. Split current clean release logic into dedicated application services and repository interfaces.
+3. Resolve policy and registry from trusted stores into immutable snapshots.
+4. Move compliance execution to `TaskManager` and persist stage events, violations and reports.
+5. Expose candidate/manifest/compliance/release operations through one facade.
+6. Rebuild API and CLI on top of the facade.
+7. Refactor TUI into a read/trigger-only client.
+
+## 2) Headless operator flow target
+
+### Candidate registration and artifact import
+
+```bash
+clean-release candidate register \
+  --candidate-id 2026.03.09-rc1 \
+  --version 1.2.0 \
+  --source-snapshot v1.2.0-rc1 \
+  --actor release-bot
+
+clean-release candidate import-artifacts \
+  --candidate-id 2026.03.09-rc1 \
+  --input artifacts.json \
+  --actor release-bot
+```
+
+### Manifest and compliance
+
+```bash
+clean-release manifest build --candidate-id 2026.03.09-rc1 --actor release-bot
+clean-release compliance run --candidate-id 2026.03.09-rc1 --manifest-id man-001 --actor release-bot --json
+clean-release compliance status --run-id run-001 --json
+clean-release compliance report --run-id run-001 --json
+```
+
+### Approval and publication
+
+```bash
+clean-release release approve --candidate-id 2026.03.09-rc1 --report-id rpt-001 --actor release-owner
+clean-release release publish --candidate-id 2026.03.09-rc1 --report-id rpt-001 --channel prod --actor release-owner
+```
+
+## 3) REST API smoke checklist
+
+- `POST /api/clean-release/candidates` creates candidate and returns overview DTO.
+- `POST /api/clean-release/candidates/{candidate_id}/artifacts/import` persists artifacts without triggering compliance.
+- `POST /api/clean-release/candidates/{candidate_id}/manifest` creates a new immutable manifest version.
+- `POST /api/clean-release/candidates/{candidate_id}/compliance-runs` returns `202` with `run_id` and `task_id`.
+- `GET /api/clean-release/compliance-runs/{run_id}` returns live execution status.
+- `GET /api/clean-release/compliance-runs/{run_id}/stages` returns ordered stage results.
+- `GET /api/clean-release/compliance-runs/{run_id}/violations` returns append-only violations.
+- `GET /api/clean-release/compliance-runs/{run_id}/report` returns immutable final report for completed runs.
+- `POST /api/clean-release/candidates/{candidate_id}/approve` enforces passed-report gate.
+- `POST /api/clean-release/candidates/{candidate_id}/publish` enforces approval gate.
+
+## 4) UX conformance checks (must pass)
+
+- TUI shows latest candidate, latest manifest, latest run and latest report without mutating them.
+- `F6` builds manifest explicitly; `F5` never auto-builds hidden manifest.
+- `F8` is disabled or blocked with explicit reason unless candidate is in `CHECK_PASSED`.
+- `F9` is disabled or blocked with explicit reason unless candidate is `APPROVED`.
+- Running state is sourced from real run/task progress, not simulated local state.
+- Non-TTY startup redirects the operator to CLI/API path instead of headless TUI mode.
+- Demo mode actions never expose or modify real-mode history.
+
+## 5) Contract checks (must pass)
+
+- Domain transitions conform to the lifecycle in [`data-model.md`](specs/025-clean-release-compliance/data-model.md).
+- API payloads conform to [`clean-release-api.openapi.yaml`](specs/025-clean-release-compliance/contracts/clean-release-api.openapi.yaml).
+- CLI commands and exit codes conform to [`cli.md`](specs/025-clean-release-compliance/contracts/cli.md).
+- Immutable entities are never updated in place.
+- Real-mode runs, reports, violations and audit events remain append-only.
+
+## 6) Suggested validation commands
+
+Backend targeted tests:
+```bash
+cd backend && .venv/bin/python3 -m pytest tests/services/clean_release tests/api/routes -k clean_release -q
+```
+
+CLI smoke tests:
+```bash
+cd backend && .venv/bin/python3 -m pytest tests/scripts/test_clean_release_cli.py -q
+```
+
+TUI thin-client smoke tests:
+```bash
+cd backend && .venv/bin/python3 -m pytest tests/scripts/test_clean_release_tui_v2.py -q
+```
+
+## 7) Migration checkpoints
+
+1. Old TUI logic no longer directly prepares candidates, builds manifests or finalizes runs.
+2. Legacy `/api/clean-release/checks*` entrypoints have explicit compatibility or deprecation behavior.
+3. Trusted policy resolution no longer depends on UI/env bootstrap payloads.
+4. Compliance run state is visible through both TaskManager and clean-release run records.
+5. Demo namespace and real namespace are visibly isolated.
+
+## 8) Validation Results (T049)
+
+### Executed regression subset
+
+Command:
+```bash
+cd backend && DATABASE_URL=sqlite:///./test_quickstart.db AUTH_DATABASE_URL=sqlite:///./test_quickstart_auth.db TASKS_DATABASE_URL=sqlite:///./test_quickstart_tasks.db PYTHONPATH=/home/busya/dev/ss-tools .venv/bin/python3 -m pytest tests/scripts/test_clean_release_cli.py tests/scripts/test_clean_release_tui_v2.py src/api/routes/__tests__/test_clean_release_v2_api.py src/api/routes/__tests__/test_clean_release_v2_release_api.py src/api/routes/__tests__/test_clean_release_legacy_compat.py -q
+```
+
+Result:
+- `15 passed`
+- exit code `0`
+- run completed with non-blocking warnings only (deprecations/config warnings), no functional failures.
+
+### Coverage of quickstart objectives
+
+- Headless lifecycle path validated through CLI smoke tests.
+- Thin-client TUI path validated through dedicated TUI v2 smoke tests.
+- V2 API and legacy compatibility API paths validated through route tests.
+- Legacy `/api/clean-release/checks*` and `/api/clean-release/candidates/prepare` compatibility confirmed.
+
+## 9) Done criteria for planning handoff
+
+- All planning artifacts exist and are internally consistent.
+- State machine, trust boundaries and immutable evidence model are defined.
+- CLI and REST contracts are stable enough for parallel implementation.
+- TUI UX reference is explicitly thin-client only.
+- Ready to decompose into executable work items via [`tasks.md`](specs/025-clean-release-compliance/tasks.md).

+# Phase 0 Research: Clean Release Compliance Subsystem Redesign
+
+## Decision 1: The subsystem becomes API/CLI-first and TUI becomes a thin client
+
+**Decision**  
+Primary release operations are owned by application services and exposed through CLI and HTTP API first. TUI is retained only as a thin operator interface that reads state and triggers actions through the same facade.
+
+**Rationale**  
+The current implementation mixes UI state with preparation, manifest creation and compliance execution. This blocks automation and makes behavior depend on the interface used.
+
+**Alternatives considered**  
+- Keep TUI as primary orchestrator and add wrappers around it: rejected because it preserves hidden business logic inside the interface.  
+- Remove TUI entirely: rejected because operators still need an interactive console flow in enterprise environments.
+
+---
+
+## Decision 2: Policy and registry are trusted snapshots, never runtime UI/env payloads
+
+**Decision**  
+Policy and source registry are resolved by a dedicated read-only resolution service from trusted stores, then frozen into immutable snapshots for each compliance run.
+
+**Rationale**  
+The redesign explicitly separates trusted and untrusted inputs. Candidate input, artifacts JSON and operator choices are not allowed to define policy contents or final report outcomes.
+
+**Alternatives considered**  
+- Continue using `.clean-release.yaml` and env bootstrap as policy source: rejected because it violates the new trust model.  
+- Let TUI construct policy in demo and real mode differently: rejected because it breaks evidence integrity and reproducibility.
+
+---
+
+## Decision 3: Manifest, report and snapshots are immutable; run history is append-only
+
+**Decision**  
+`DistributionManifest`, `CleanPolicySnapshot`, `SourceRegistrySnapshot`, `ComplianceReport`, `ApprovalDecision` and `PublicationRecord` are immutable. `ComplianceRun`, `ComplianceStageRun`, `ComplianceViolation` and audit log are append-only once created; only non-terminal run fields may progress during execution.
+
+**Rationale**  
+The main value of the subsystem is evidence integrity. Mutable manifest/report records make audit and publication safety unverifiable.
+
+**Alternatives considered**  
+- Update manifest/report in place: rejected because historical evidence would be lost.  
+- Allow deleting old runs to keep storage small: rejected because real mode must preserve evidence.
+
+---
+
+## Decision 4: Release lifecycle is modeled as an explicit state machine
+
+**Decision**  
+The candidate lifecycle is formalized as `DRAFT -> PREPARED -> MANIFEST_BUILT -> CHECK_PENDING -> CHECK_RUNNING -> CHECK_PASSED|CHECK_BLOCKED|CHECK_ERROR -> APPROVED -> PUBLISHED -> REVOKED`, with hard guards on forbidden transitions.
+
+**Rationale**  
+Current logic spreads status changes across TUI and orchestration code. A formal state machine makes approval/publication gating deterministic and testable.
+
+**Alternatives considered**  
+- Keep loose status updates per module: rejected because it produces hidden invalid states.  
+- Collapse all states into a smaller set: rejected because manifest, check and approval stages need separate audit visibility.
+
+---
+
+## Decision 5: Compliance execution is a pluggable stage pipeline integrated with TaskManager
+
+**Decision**  
+Each compliance run becomes a `TaskManager` task. The run stores lifecycle metadata while stage logs are emitted as task logs or structured sub-events. The pipeline remains pluggable with stage-specific decisions and violations.
+
+**Rationale**  
+The repository already has a mature async task lifecycle and reporting patterns. Reusing it reduces duplicated orchestration infrastructure and aligns with repository constitution.
+
+**Alternatives considered**  
+- Keep synchronous orchestrator execution: rejected due to non-blocking API requirements.  
+- Build a second custom task subsystem inside clean release: rejected as redundant and harder to observe.
+
+---
+
+## Decision 6: Interfaces are split into CLI, REST API and thin TUI over one facade
+
+**Decision**  
+A single `CleanReleaseFacade` exposes use cases for candidate overview, manifest build, compliance run, approval and publication. CLI, API and TUI all call the facade. Headless mode belongs to CLI/API only.
+
+**Rationale**  
+A facade keeps interface code thin and prevents re-implementing business rules per entrypoint.
+
+**Alternatives considered**  
+- Let each interface call lower-level services directly: rejected because state validation and DTO assembly would drift.  
+- Keep a headless branch inside TUI: rejected because headless is not a UI concern.
+
+---
+
+## Decision 7: Repositories are decomposed by responsibility, even if exposed through one internal facade
+
+**Decision**  
+Persistence is split by bounded responsibility: candidate, artifacts, manifest, policy, compliance run, report, approval, publication and audit. A convenience facade may exist, but ownership remains explicit.
+
+**Rationale**  
+The current `CleanReleaseRepository` is too broad for the redesigned evidence model. Explicit repository boundaries make append-only and immutable behavior easier to enforce.
+
+**Alternatives considered**  
+- Keep one universal repository class: rejected because contracts stay ambiguous.  
+- Persist everything only through TaskManager: rejected because domain entities need direct retrieval independently of task history.
+
+---
+
+## Decision 8: Demo mode is preserved but isolated by namespace
+
+**Decision**  
+Demo mode is handled by a dedicated demo service and isolated storage namespace. Demo runs, policies, candidates and reports never share identifiers or history with real mode.
+
+**Rationale**  
+Demo mode remains useful for operator training, but it must not contaminate real compliance evidence.
+
+**Alternatives considered**  
+- Simulate demo behavior inside real storage: rejected because it risks false evidence and operator confusion.  
+- Drop demo mode entirely: rejected because it removes a safe training path.
+
+---
+
+## Decision 9: Migration proceeds incrementally, starting by extracting services out of TUI
+
+**Decision**  
+Migration starts by extracting build/run logic into new services/facade, then removes env-driven policy injection, then introduces immutable snapshots, then adds CLI/API contracts, and only after that thins the TUI.
+
+**Rationale**  
+The current codebase already has working routes, models and tests. A big-bang rewrite would create unnecessary integration risk.
+
+**Alternatives considered**  
+- Rewrite the whole subsystem at once: rejected because it is harder to validate incrementally.  
+- Patch TUI only: rejected because it does not solve the architectural problem.

+# Feature Specification: Clean Release Compliance Subsystem Redesign
+
+**Feature Branch**: `025-clean-release-compliance`  
+**Created**: 2026-03-09  
+**Status**: Draft  
+**Input**: User description: "Редизайн текущего clean release TUI-checker в нормальную API/CLI-first release/compliance subsystem с разделением domain/application/infrastructure/interfaces, immutable snapshots, append-only compliance evidence, approval/publication flow, thin TUI client, REST API и интеграцией с TaskManager."
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Headless candidate and manifest lifecycle (Priority: P1)
+
+Как release-менеджер или CI pipeline, я хочу регистрировать релиз-кандидат, импортировать артефакты и строить manifest без TUI, чтобы вход в release workflow был воспроизводимым в автоматизированном или headless сценарии.
+
+**Why this priority**: Это базовая ценность редизайна. Пока жизненный цикл кандидата зависит от TUI, release flow не годится для автоматизации и надёжного enterprise use.
+
+**Independent Test**: Можно создать кандидата, импортировать набор артефактов, построить manifest и запросить overview только через CLI или HTTP API, не используя интерактивный интерфейс.
+
+**Acceptance Scenarios**:
+
+1. **Given** у оператора есть описание релиз-кандидата и набор артефактов, **When** он выполняет headless workflow регистрации, импорта и построения manifest, **Then** система сохраняет кандидата и immutable snapshot manifest без участия TUI.
+2. **Given** manifest успешно построен, **When** оператор запрашивает candidate overview через CLI или API, **Then** он получает актуальный lifecycle state и идентификатор latest manifest.
+3. **Given** pipeline подготавливает следующий этап release workflow, **When** он использует headless candidate and manifest operations, **Then** ему не требуется интерактивный интерфейс для продолжения release process.
+
+---
+
+### User Story 2 - Trusted and immutable compliance evidence (Priority: P1)
+
+Как сотрудник комплаенса или аудита, я хочу, чтобы policy, registry, manifest, run, violations и report были отделены друг от друга и сохранялись как доверенные или append-only сущности, чтобы итог выпуска был доказуемым и не зависел от UI-состояния или случайных env/json подмен.
+
+**Why this priority**: Главная архитектурная проблема текущего решения - смешение trust boundaries и UI logic с бизнес-решениями. Без исправления этого нельзя считать результат compliance надёжным.
+
+**Independent Test**: Можно зафиксировать policy snapshot и registry snapshot, выполнить run, затем проверить, что manifest/report/violations не переписывались и что итоговый статус выводится только из сохранённого evidence.
+
+**Acceptance Scenarios**:
+
+1. **Given** активная policy получена из доверенного policy store, **When** запускается compliance, **Then** run использует snapshot policy и snapshot registry, а не значения из UI или временных env-переменных.
+2. **Given** для кандидата уже создан manifest, **When** входные данные кандидата меняются, **Then** система создаёт новый version manifest вместо изменения существующего snapshot.
+3. **Given** run завершён, **When** оператор запрашивает историю проверки, **Then** старые run, violations и reports остаются доступными и не удаляются в real mode.
+
+---
+
+### User Story 3 - Controlled approval and publication gate (Priority: P2)
+
+Как владелец релиза, я хочу выполнять approve, publish и revoke только после валидного compliance результата, чтобы состояние выпуска было формально управляемым и не зависело от ручных договорённостей.
+
+**Why this priority**: Проверка compliance имеет смысл только тогда, когда она реально управляет дальнейшими переходами release lifecycle.
+
+**Independent Test**: Можно попытаться утвердить или опубликовать кандидата в запрещённом состоянии и убедиться, что система блокирует переход; затем пройти валидный путь `CHECK_PASSED -> APPROVED -> PUBLISHED`.
+
+**Acceptance Scenarios**:
+
+1. **Given** кандидат имеет последний report со статусом `PASSED`, **When** уполномоченный оператор выполняет approve, **Then** система фиксирует approval decision и переводит кандидата в состояние `APPROVED`.
+2. **Given** кандидат не имеет успешного compliance report или latest approval decision имеет значение `REJECTED`, **When** оператор пытается выполнить approve или publish вне допустимого правила, **Then** система отклоняет действие и сообщает причину блокировки.
+3. **Given** кандидат опубликован в целевой канал, **When** требуется отзыв выпуска, **Then** система создаёт publication revocation record без удаления исходной истории публикации.
+
+---
+
+### User Story 4 - Thin operational interfaces (Priority: P3)
+
+Как инженер сопровождения, я хочу использовать TUI и другие интерфейсы только как клиенты чтения и запуска операций, чтобы интерфейсы не содержали скрытой бизнес-логики, не подменяли policy и не создавали визуальные fake-runs.
+
+**Why this priority**: Тонкие интерфейсы упрощают сопровождение, делают поведение одинаковым между CLI, API, TUI и будущим Web UI, а также уменьшают риск расхождения логики.
+
+**Independent Test**: Можно открыть TUI, выполнить build manifest, run compliance, approve и publish, а затем проверить, что все операции и их последствия совпадают с CLI/API сценариями и не зависят от внутреннего UI state.
+
+**Acceptance Scenarios**:
+
+1. **Given** оператор открывает TUI, **When** он запускает build manifest или compliance, **Then** TUI вызывает application services и только отображает актуальные DTO/статусы.
+2. **Given** система работает в demo mode, **When** оператор запускает demo workflow, **Then** demo данные и demo history остаются полностью изолированными от real mode.
+3. **Given** оператор работает в headless окружении без TTY, **When** он пытается использовать функциональность release lifecycle, **Then** система направляет его в CLI/API путь, а не переводит TUI в скрытый псевдо-headless режим.
+
+### Edge Cases
+
+- Что происходит, если артефакт имеет расхождение между `declared_category` и `detected_category`?
+- Что происходит, если кандидат изменился после построения manifest, но до запуска compliance?
+- Как система различает business blocked, invalid input и system error при возврате статуса и exit code?
+- Что происходит, если policy store недоступен в момент запроса compliance?
+- Как обрабатывается повторный approve или повторный publish для уже терминально обработанного кандидата?
+- Что происходит, если run был отменён или task crashed после старта, но до генерации report?
+- Как система предотвращает пересечение demo namespace и real namespace в storage и audit history?

+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: 100% обязательных действий release lifecycle для стандартного сценария (`register -> import-artifacts -> build-manifest -> run-compliance -> approve -> publish`) выполняются без TUI через CLI или API.
+- **SC-002**: 100% завершённых compliance runs оставляют неизменяемый report и связанный audit trail, доступный для чтения после завершения.
+- **SC-003**: 100% попыток approve без успешного compliance result и publish без approval отклоняются системой.
+- **SC-004**: Не менее 95% стандартных запусков compliance получают machine-readable outcome без ручного исправления состояния системы.
+- **SC-005**: Не менее 90% операторов могут пройти базовый release workflow по quickstart без обращения к скрытым TUI-сценариям или ручным DB-операциям.
+- **SC-006**: Время получения идентификатора run/task после запроса запуска compliance не превышает 2 секунд для типового кандидата.
+- **SC-007**: В 100% real-mode сценариев historical runs, violations, reports и audit events не удаляются командами пользовательского интерфейса.
+
+## Assumptions
+
+- В проекте уже доступен общий TaskManager, пригодный для оркестрации long-running compliance tasks.
+- Для policy и registry может быть предоставлен доверенный read-only источник, отдельный от пользовательского UI input.
+- Существующий clean-release модуль допускает поэтапную миграцию без одномоментного удаления старых API/TUI entrypoints.
+- Операторы релиза, approval actors и publication actors аутентифицированы существующими механизмами приложения.
+- Demo mode нужен для демонстрации и тестовых сценариев, но не должен влиять на real mode evidence.

+
+## Phase 3: User Story 1 - Headless release candidate lifecycle (Priority: P1) 🎯 MVP
+
+**Goal**: Make candidate registration, artifact import, manifest build and lifecycle visibility available through CLI/API without TUI.

+
+### Implementation for User Story 1
+
+- [x] T014 [US1] Implement candidate preparation service in `backend/src/services/clean_release/candidate_service.py` (CRITICAL: PRE unique candidate id and valid artifacts; POST candidate/artifacts persisted and status advances only through legal states; TESTS: duplicate id, malformed artifact input, empty artifact set)
+- [x] T015 [US1] Implement manifest service in `backend/src/services/clean_release/manifest_service.py` (CRITICAL: PRE candidate prepared and artifacts available; POST immutable manifest snapshot with deterministic digest and version increment; TESTS: rebuild creates new version, existing manifest cannot be mutated, missing candidate rejected)
+- [x] T016 [US1] Implement policy resolution service with trusted snapshot reads in `backend/src/services/clean_release/policy_resolution_service.py` (CRITICAL: PRE trusted profile exists; POST immutable policy and registry snapshots without UI/env overrides; TESTS: missing profile, missing registry, override attempt)

+
+**Checkpoint**: US1 independently functional and usable from headless automation.
+
+---
+
+## Phase 4: User Story 2 - Trusted and immutable compliance evidence (Priority: P1)
+
+**Goal**: Execute compliance as an observable, append-only TaskManager-backed pipeline with immutable reports and trusted snapshots.
+
+**Independent Test**: Start a run through API/CLI, observe task/run progress, inspect stage records and violations, then verify immutable final report persistence.
+
+### Tests for User Story 2

+- [x] T024 [US2] Implement compliance execution service in `backend/src/services/clean_release/compliance_execution_service.py` (CRITICAL: PRE candidate exists and explicit or latest manifest plus trusted snapshots are resolvable; POST run, stage records, violations and report remain mutually consistent; TESTS: run without manifest, task crash mid-run, blocked report finalization)
+- [x] T025 [US2] Bind compliance runs to TaskManager and reports service in `backend/src/services/clean_release/compliance_execution_service.py`, `backend/src/services/reports/report_service.py` and `backend/src/dependencies.py`
+- [x] T026 [US2] Implement compliance REST endpoints for run creation, run status, stages, violations and report in `backend/src/api/routes/clean_release.py`
+- [x] T027 [US2] Implement compliance CLI commands (`run`, `status`, `report`, `violations`) in `backend/src/scripts/clean_release_cli.py` with latest-manifest fallback when `--manifest-id` is omitted
+- [x] T028 [US2] Implement append-only audit hooks for run lifecycle and violations in `backend/src/services/clean_release/audit_service.py`
+- [x] T029 [US2] Verify implementation matches [`ux_reference.md`](specs/025-clean-release-compliance/ux_reference.md) (Happy Path & Errors)
+
+**Checkpoint**: US2 independently functional with real run evidence and immutable reporting.
+
+---
+
+## Phase 5: User Story 3 - Controlled approval and publication gate (Priority: P2)
+
+**Goal**: Enforce legal approval/publication transitions over completed compliance results.
+
+**Independent Test**: Attempt invalid approve/publish transitions, then complete the valid `CHECK_PASSED -> APPROVED -> PUBLISHED -> REVOKED` flow.
+
+### Tests for User Story 3
+

+
+### Implementation for User Story 3
+
+- [x] T033 [US3] Implement approval service in `backend/src/services/clean_release/approval_service.py` (CRITICAL: PRE report belongs to candidate and final status is PASSED for approve; POST immutable decision persisted, approve may advance candidate state, reject blocks publication gate without rewriting compliance evidence; TESTS: approve blocked report, approve foreign report, duplicate approve, reject then publish)
+- [x] T034 [US3] Implement publication service in `backend/src/services/clean_release/publication_service.py` (CRITICAL: PRE candidate approved; POST immutable publication/revocation record and legal state transition; TESTS: publish without approval, revoke unknown publication, republish after revoke)
+- [x] T035 [US3] Implement release CLI commands (`approve`, `reject`, `publish`, `revoke`) in `backend/src/scripts/clean_release_cli.py`
+- [x] T036 [US3] Implement release REST endpoints in `backend/src/api/routes/clean_release.py`
+- [x] T037 [US3] Extend facade overview/read models for policy snapshot, approval and publication state in `backend/src/services/clean_release/facade.py` and `backend/src/services/clean_release/dto.py`
+- [x] T038 [US3] Verify implementation matches [`ux_reference.md`](specs/025-clean-release-compliance/ux_reference.md) (Happy Path & Errors)
+
+**Checkpoint**: US3 independently functional with explicit release gates.
+
+---
+
+## Phase 6: User Story 4 - Thin operational interfaces (Priority: P3)
+
+**Goal**: Convert TUI into a real thin client and isolate demo behavior from real-mode evidence.
+
+**Independent Test**: Operate the same candidate through TUI using facade-backed actions and confirm that TUI behavior matches CLI/API semantics without hidden side effects.
+
+### Tests for User Story 4
+

+- [x] T041 [P] [US4] Add non-TTY startup behavior tests in `backend/tests/scripts/test_clean_release_tui_v2.py`
+
+### Implementation for User Story 4
+
+- [x] T042 [US4] Refactor TUI to call only facade methods and render DTOs in `backend/src/scripts/clean_release_tui.py` (CRITICAL: PRE valid TTY and candidate context; POST no hidden manifest/policy/run mutations outside facade; TESTS: no TTY, missing manifest on F5, blocked report on F8)
+- [x] T043 [US4] Implement isolated demo data service and namespace handling in `backend/src/services/clean_release/demo_data_service.py` and `backend/src/services/clean_release/repositories/`
+- [x] T044 [US4] Remove real-mode `clear_history` and pseudo-headless fallback behavior in `backend/src/scripts/clean_release_tui.py`
+- [x] T045 [US4] Implement TUI overview panels and action keys `F5/F6/F7/F8/F9/F10` aligned with facade DTOs in `backend/src/scripts/clean_release_tui.py`
+- [x] T046 [US4] Verify implementation matches [`ux_reference.md`](specs/025-clean-release-compliance/ux_reference.md) (Happy Path & Errors)
+
+**Checkpoint**: US4 independently functional with thin-client TUI and isolated demo mode.
+
+---
+
+## Phase 7: Polish & Cross-Cutting Concerns
+
+**Purpose**: Finalize migration, compatibility and operational documentation.
+
+- [x] T047 [P] Add compatibility/deprecation tests for legacy `/api/clean-release/checks*` and `/api/clean-release/candidates/prepare` paths in `backend/src/api/routes/__tests__/test_clean_release_legacy_compat.py`
+- [x] T048 [P] Update operational documentation for new CLI/API/TUI workflow in `README.md` and `docs/installation.md`
+- [x] T049 Run end-to-end quickstart validation and capture results in `specs/025-clean-release-compliance/quickstart.md`
+- [x] T050 Migrate or wrap legacy clean release modules in `backend/src/services/clean_release/preparation_service.py`, `backend/src/services/clean_release/manifest_builder.py`, `backend/src/services/clean_release/compliance_orchestrator.py` and `backend/src/services/clean_release/repository.py`
+- [x] T051 Align clean release report surfacing with shared reports/task views in `backend/src/services/reports/report_service.py` and `backend/src/api/routes/reports.py`
+- [x] T052 Run semantic compliance review for touched clean release modules and close critical `[DEF]`/contract gaps in `backend/src/models/clean_release.py`, `backend/src/services/clean_release/` and `backend/src/scripts/clean_release_tui.py`
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Phase 1 (Setup)**: No dependencies.
+- **Phase 2 (Foundational)**: Depends on Phase 1 and blocks all stories.
+- **Phase 3 (US1)**: Depends on Phase 2.
+- **Phase 4 (US2)**: Depends on Phase 2 and reuses outputs from US1 trusted snapshot and facade work.
+- **Phase 5 (US3)**: Depends on Phase 2 and a stable report model from US2.
+- **Phase 6 (US4)**: Depends on Phases 3-5 because TUI must sit on stable facade/API semantics.
+- **Phase 7 (Polish)**: Depends on all selected stories.
+
+### User Story Dependencies
+
+- **US1 (P1)**: First deliverable and MVP.
+- **US2 (P1)**: Depends on facade/repository foundations and benefits from US1 candidate/manifest flow.
+- **US3 (P2)**: Depends on successful report persistence from US2.
+- **US4 (P3)**: Depends on stable facade and release-gate behavior from US1-US3.
+
+Graph: `US1 -> US2 -> US3 -> US4`
+
+### Parallel Opportunities
+
+- Setup tasks T002, T003, T004.
+- Foundational tasks T007 and T008 after T005/T006 are stable.
+- US1 tests T011, T012, T013.
+- US2 tests T020, T021, T022.
+- US3 tests T030, T031, T032.
+- US4 tests T039, T040, T041.
+- Polish tasks T047 and T048.
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+Task: "T011 [US1] Add lifecycle and manifest tests in backend/tests/services/clean_release/test_candidate_manifest_services.py"
+Task: "T012 [US1] Add API contract tests in backend/src/api/routes/__tests__/test_clean_release_v2_api.py"
+Task: "T013 [US1] Add CLI smoke tests in backend/tests/scripts/test_clean_release_cli.py"
+```
+
+## Parallel Example: User Story 2
+
+```bash
+Task: "T020 [US2] Add stage pipeline tests in backend/tests/services/clean_release/test_compliance_execution_service.py"
+Task: "T021 [US2] Add TaskManager integration tests in backend/tests/services/clean_release/test_compliance_task_integration.py"
+Task: "T022 [US2] Add report immutability tests in backend/tests/services/clean_release/test_report_audit_immutability.py"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (Recommended)
+
+1. Complete Phase 1 and Phase 2.
+2. Deliver Phase 3 (US1) so candidate lifecycle works headlessly through CLI/API.
+3. Validate independent test for US1.
+4. Then add US2 for trusted compliance evidence before moving to release gates and TUI refactor.
+
+### Incremental Delivery
+
+1. US1: headless candidate lifecycle.
+2. US2: trusted compliance execution + immutable evidence.
+3. US3: approval/publication gate.
+4. US4: thin TUI + demo isolation.
+5. Phase 7: compatibility, docs and semantic cleanup.
+
+### UX Preservation Rule
+
+No task in this plan is allowed to reintroduce hidden business logic into TUI or to degrade the explicit operator flow in [`ux_reference.md`](specs/025-clean-release-compliance/ux_reference.md).  
+Each user story contains a mandatory UX verification task: T019, T029, T038, T046.

+# UX Reference: Clean Release Compliance Subsystem Redesign
+
+**Feature Branch**: `025-clean-release-compliance`  
+**Created**: 2026-03-09  
+**Status**: Draft
+
+## 1. User Persona & Context
+
+- **Who is the user?**: Release manager, compliance operator, enterprise support engineer.
+- **What is their goal?**: Safely move a release candidate through candidate preparation, compliance, approval and publication without hidden state.
+- **Context**: Usually works in terminal-first infrastructure, often in restricted or headless environments, sometimes with a TTY, sometimes from CI.
+
+## 2. The Happy Path Narrative
+
+Оператор регистрирует кандидата и импортирует артефакты через CLI или API. Затем он открывает TUI и сразу видит candidate overview: latest manifest, active policy snapshot, latest run, violations и publication state. Нажатие `F6` строит manifest, `F5` запускает compliance, а экран показывает реальный прогресс stage-by-stage из task/run logs, а не локальную имитацию. После `PASSED` оператор выполняет `F8` approve и `F9` publish, и каждое действие мгновенно отражается в overview без скрытых сайд-эффектов.
+
+## 3. Interface Mockups
+
+### CLI Interaction
+
+```bash
+$ clean-release candidate register \
+    --candidate-id 2026.03.09-rc1 \
+    --version 1.2.0 \
+    --source-snapshot v1.2.0-rc1
+
+Candidate created: 2026.03.09-rc1
+Status: DRAFT
+
+$ clean-release manifest build --candidate-id 2026.03.09-rc1
+Manifest created: man-001
+Manifest digest: sha256:9fa...
+Status: MANIFEST_BUILT
+
+$ clean-release compliance run --candidate-id 2026.03.09-rc1 --json
+{
+  "run_id": "run-001",
+  "candidate_id": "2026.03.09-rc1",
+  "status": "PENDING",
+  "task_id": "task-123"
+}
+```
+
+### TUI Layout & Flow
+
+**Screen/Component**: Clean Release Overview
+
+- **Layout**: Three-pane terminal layout.
+  - Top header: current candidate, lifecycle state, active mode (`real` or `demo`).
+  - Left pane: candidate summary, latest manifest, approval/publication state.
+  - Right pane: latest compliance run, stage timeline, violations list.
+  - Bottom action bar: `F5 Run`, `F6 Manifest`, `F7 Refresh`, `F8 Approve`, `F9 Publish`, `F10 Exit`.
+- **Key Elements**:
+  - **Candidate Summary**: shows candidate id, version, source snapshot, current state.
+  - **Latest Manifest Card**: manifest id, version, digest, created time.
+  - **Policy Snapshot Card**: policy id/version and registry version used for latest run.
+  - **Violations Table**: severity, code, artifact path, short message.
+- **States**:
+  - **Default**: Existing overview visible, no hidden mutation.
+  - **Running**: Current run and current stage are highlighted; logs update live from task events.
+  - **Passed**: Action bar enables `Approve` when transition is legal.
+  - **Blocked/Error**: Violations or failure reason become the dominant focus; approval/publish actions stay disabled.
+
+## 4. The Error Experience
+
+**Philosophy**: Surface the real state and tell the operator what transition is blocked. Never hide missing prerequisites by auto-fixing them in the UI.
+
+### Scenario A: Missing Manifest
+
+- **User Action**: Presses `F5` to run compliance before a manifest exists.
+- **System Response**:
+  - TUI: inline error banner `Manifest required before compliance run` and highlight on `F6 Build manifest`.
+  - CLI: `Error: candidate 2026.03.09-rc1 has no manifest. Build a manifest first.`
+- **Recovery**: Operator runs build manifest, returns to overview, retries compliance.
+
+### Scenario B: Blocked By Policy
+
+- **System Response**: Run ends in `BLOCKED`, latest report card turns warning state, violations table is focused automatically.
+- **Recovery**: Operator can inspect violations, export/report details, fix candidate inputs, build a new manifest and request a new run.
+
+### Scenario C: Policy Store Unavailable
+
+- **System Response**: Request is rejected as input/system error before stage execution; UI explicitly says policy snapshot could not be resolved.
+- **Recovery**: Retry when trusted policy source is restored. No fake run is shown.
+
+### Scenario D: Headless Environment
+
+- **System Response**: TUI refuses to start without TTY and instructs operator to use CLI/API flow.
+- **Recovery**: Run equivalent `clean-release ...` command or call API.
+
+## 5. Tone & Voice
+
+- **Style**: Concise, operational, deterministic.
+- **Terminology**: Use `candidate`, `manifest`, `policy snapshot`, `compliance run`, `report`, `approval`, `publication` consistently.
+- **Avoided Terms**: Avoid vague legacy words like `checker`, `fake run`, `history cleanup`, `headless ready` inside the operator UX.
