@@ -39,6 +39,23 @@ The settings API is available at `/settings`:
 
 The settings page is located at `frontend/src/pages/Settings.svelte`. It provides forms for managing global settings and Superset environments.
 
+## Reports Center
+
+Unified reports are available at [`/reports`](frontend/src/routes/reports/+page.svelte) and use the backend API at [`/api/reports`](backend/src/api/routes/reports.py) and [`/api/reports/{report_id}`](backend/src/api/routes/reports.py).
+
+### What operators can do
+
+- View all task outcomes (LLM verification, backup, migration, documentation) in one list.
+- Filter by type and status.
+- Open report detail with diagnostics and recommended next actions.
+- Continue working even for unknown task types and partial payloads (explicit placeholders are shown instead of hidden data).
+
+### Troubleshooting
+
+- If report list is empty, verify tasks exist and clear filters.
+- If report detail is not found (404), confirm the selected report still exists in task history.
+- If report API tests fail during local execution with database connectivity errors, ensure the configured DB is reachable or run in an environment with available test DB services.

+# Module Contracts: Frontend Style Unification
+
+## [DEF:FrontendStyleSystem:Module]
+@TIER: CRITICAL  
+@PURPOSE: Define and enforce unified visual primitives and page-shell rules across targeted frontend routes.  
+@RELATION: DEPENDS_ON -> [DEF:Std:UI_Svelte]  
+@RELATION: DEPENDS_ON -> [DEF:Std:Semantics]  
+@RELATION: BINDS_TO -> [DEF:StyleTokenGroup:Entity]  
+@RELATION: BINDS_TO -> [DEF:UIPatternRule:Entity]  
+@PRE: Target routes/components for unification are identified and included in scope.  
+@PRE: Existing behavior-critical user flows remain available for validation.  
+@POST: Shared visual primitives and shell patterns are applied consistently in targeted scope.  
+@POST: No critical functional flow is removed by style refactor.  
+@UX_STATE: Default -> Users see consistent hierarchy (title/actions/content) across targeted pages.  
+@UX_STATE: Loading -> Loading visuals appear in consistent zones without disruptive layout jumps.  
+@UX_STATE: Error -> Error blocks use consistent emphasis and include a clear recovery action.  
+@UX_STATE: Success -> Confirmation messages follow one tone/placement pattern.  
+@INVARIANT: Unified styling must not regress accessibility-visible focus and readable contrast behavior.
+
+---
+
+## [DEF:RouteShellContract:Component]
+@TIER: CRITICAL  
+@PURPOSE: Standardize route shell structure for primary pages (dashboards, tasks, reports, settings).  
+@RELATION: DEPENDS_ON -> [DEF:FrontendStyleSystem:Module]  
+@PRE: Route provides title context and action area metadata.  
+@POST: Route renders canonical shell order: context/breadcrumbs, title block, action region, content container.  
+@UX_STATE: Default -> Primary action location is discoverable quickly and consistently.  
+@UX_STATE: Empty -> Empty-state container is visually aligned with shell and includes next-step guidance.  
+@UX_RECOVERY: Empty -> User can recover using explicit action (refresh/filter adjust/create flow).
+
+---
+
+## [DEF:StateFeedbackContract:Component]
+@TIER: CRITICAL  
+@PURPOSE: Normalize loading/empty/error/success feedback rendering and wording across modules.  
+@RELATION: DEPENDS_ON -> [DEF:StatePresentationPattern:Entity]  
+@PRE: Module can expose current state category (loading/empty/error/success).  
+@POST: State-specific UI uses canonical placement, tone, and recovery behavior.  
+@UX_STATE: Loading -> Consistent indicator style and placement with stable layout rhythm.  
+@UX_STATE: Empty -> Neutral message + guidance action rendered in standard block.  
+@UX_STATE: Error -> Actionable error messaging with retry/fix path.  
+@UX_STATE: Success -> Concise confirmation in standard visual language.  
+@UX_FEEDBACK: Error -> Emphasis clearly distinguishes failure from neutral status.  
+@UX_RECOVERY: Error -> Retry or corrective action is always visible when recoverable.  
+@INVARIANT: State texts use canonical terminology and remain i18n-compatible.

+## [DEF:TerminologyConsistencyContract:Module]
+@TIER: STANDARD  
+@PURPOSE: Keep user-facing wording consistent across page shells and state blocks.  
+@RELATION: DEPENDS_ON -> [DEF:Std:Constitution]  
+@PRE: Canonical term list for targeted flows is defined.  
+@POST: Targeted modules avoid mixed synonyms for the same concept.  
+@UX_STATE: Default -> UI labels and status texts remain concise and confidence-building.  
+@INVARIANT: User-facing text remains compatible with existing localization workflow.

+
+## Contract Usage Simulation (Key Scenario)
+
+**Scenario**: User navigates from dashboards to reports and encounters a failed data load.
+
+1. `RouteShellContract` ensures both pages keep identical shell rhythm and action placement.
+2. `FrontendStyleSystem` ensures shared primitives (spacing/typography/cards/buttons) are consistent.
+3. `StateFeedbackContract` renders failure using canonical error block with explicit retry action.
+4. `TerminologyConsistencyContract` ensures error wording and action labels are aligned across pages.
+
+**Continuity Check**: No interface mismatch detected between shell-level structure and state-level feedback contracts.

+# Implementation Plan: Frontend Style Unification
+
+**Branch**: `[001-unify-frontend-style]` | **Date**: 2026-02-23 | **Spec**: [spec.md](./spec.md)  
+**Input**: Feature specification from `/specs/001-unify-frontend-style/spec.md`
+
+## Summary
+
+Unify the frontend visual system and interaction patterns across primary product routes so users experience a coherent, predictable interface.  
+The implementation approach is to standardize shared UI primitives and page-shell patterns first, then align navigation and state feedback patterns, while preserving existing behavior and i18n/accessibility constraints. UX consistency in `ux_reference.md` is treated as a hard requirement and mapped to concrete component contracts and verification steps.
+
+## Technical Context
+
+**Language/Version**: Node.js 18+ runtime, SvelteKit (existing frontend stack)  
+**Primary Dependencies**: SvelteKit, Tailwind CSS, existing frontend UI primitives under `frontend/src/lib/components/ui`  
+**Storage**: N/A (UI styling and component behavior only)  
+**Testing**: Vitest + existing frontend component/store tests  
+**Target Platform**: Web browser (desktop-first internal product UI)  
+**Project Type**: Web application (frontend + backend repository, frontend-focused scope)  
+**Performance Goals**: Preserve existing perceived responsiveness; avoid layout shifts in loading/error/success/empty states  
+**Constraints**:  
+- Must follow Tailwind-first styling and avoid introducing native `fetch` usage (Constitution)  
+- Must keep user-facing text compatible with existing i18n strategy  
+- Must not regress core task flows while refactoring UI  
+- Must preserve accessibility-visible focus and readable contrast behavior  
+**Scale/Scope**: Core primary routes and shared layout/components used by dashboards, tasks, reports, settings
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+- ✅ **Semantic Protocol Compliance**: Planned artifacts include contracts with `[DEF]`/`@TIER`/`@PRE`/`@POST`/`@UX_STATE` for affected modules in `contracts/modules.md`.
+- ✅ **Unified Frontend Experience**: Scope is frontend style unification with Tailwind-first constraints; i18n consistency explicitly included.
+- ✅ **Independent Testability**: Spec includes independent tests per user story; quickstart includes isolated verification flows.
+- ✅ **Architecture Integrity**: No plugin or backend execution model changes required; frontend-only structural alignment.
+- ⚠️ **Known Repository Risk (External to this feature)**: Multiple `specs/001-*` directories exist in repo and trigger script warnings. Feature plan continues with explicit active feature directory `specs/001-unify-frontend-style`.

+**Structure Decision**: Use existing web-application layout and implement changes primarily in `frontend/src/lib/components`, `frontend/src/routes`, and related frontend tests.
+
+## Phase 0: Research Focus
+
+1. Standardize style baseline strategy for existing Tailwind-based Svelte components.
+2. Define migration strategy for legacy/non-conformant components without behavior regression.
+3. Define UX-consistent state patterns (loading/empty/error/success) reusable across pages.
+4. Define i18n and accessibility safeguards during style unification.
+5. Define validation approach (visual conformance + behavior safety checks).
+
+## Phase 1: Design & Contracts Outputs
+
+- Produce `data-model.md` with style/token/pattern/conformance entities.
+- Produce `contracts/modules.md` with semantic contracts and UX states for critical modules.
+- Produce `quickstart.md` with executable validation steps for independent scenario checks.
+- Re-run Constitution check after design to confirm no UX compromise.
+
+## Complexity Tracking
+
+No constitution violations requiring explicit exceptions.

+# Quickstart: Frontend Style Unification
+
+## Purpose
+
+Validate that frontend style unification is implemented consistently across targeted routes without functional regressions.
+
+## Preconditions
+
+- Feature branch: `001-unify-frontend-style`
+- Frontend dependencies installed
+- Application starts successfully in local environment
+- Target routes available: dashboards, tasks, reports, settings
+
+## Validation Flow
+
+### 1) User Story 1 — Consistent Visual Foundation (P1)
+
+1. Open each target route: dashboards, tasks, reports, settings.
+2. Compare visual primitives:
+   - typography hierarchy
+   - spacing rhythm
+   - card/container style
+   - button variant consistency
+3. Confirm no route has conflicting visual language for shared primitives.
+
+**Expected Result**: Shared visual baseline appears coherent across all targeted routes.
+
+---
+
+### 2) User Story 2 — Unified Navigation and Page Shells (P2)
+
+1. Navigate through at least three top-level routes.
+2. Verify shell consistency:
+   - page title placement
+   - context/breadcrumb area behavior
+   - primary/secondary action region location
+   - content container alignment
+3. Confirm transitions do not break orientation cues.
+
+**Expected Result**: Page shell pattern is consistent and predictable across routes.
+
+---
+
+### 3) User Story 3 — Predictable Feedback and States (P3)
+
+1. Trigger loading state on at least two routes.
+2. Trigger empty state and error state where possible.
+3. Trigger one success feedback event (save/update/apply action).
+4. Compare message tone, placement, and recovery actions.
+
+**Expected Result**: Loading/empty/error/success feedback follows one canonical pattern.
+
+---
+
+## Regression Safety Checks
+
+1. Execute core functional flows on dashboards/tasks/reports/settings.
+2. Confirm style unification did not remove or alter business-critical actions.
+3. Confirm focus visibility and readability remain acceptable on updated UI areas.
+
+**Expected Result**: No critical user flow regression and no accessibility degradation.
+
+---
+
+## Conformance Checklist Snapshot
+
+- [ ] Shared primitives aligned in targeted scope
+- [ ] Page shell contract honored
+- [ ] State feedback contract honored
+- [ ] Terminology/tone consistency preserved

+# Research: Frontend Style Unification
+
+## Decision 1: Tailwind-first unification through shared primitives and layout patterns
+
+**Decision**: Use existing shared UI components and route-level layout patterns as the primary unification mechanism, with Tailwind utility classes as the style source of truth.
+
+**Rationale**:
+- Aligns with constitution requirement: Tailwind-first and minimal scoped styles.
+- Reduces risk versus page-by-page ad-hoc class rewrites.
+- Enables predictable rollout and easier review by centralizing style behavior.
+
+**Alternatives considered**:
+- Big-bang rewrite of all pages in one pass (rejected: high regression risk).
+- Introducing a second styling abstraction layer (rejected: added complexity and drift).
+
+---
+
+## Decision 2: Incremental conformance with explicit exception registry
+
+**Decision**: Apply style unification incrementally across core routes; for non-conformant legacy widgets, use documented fallback styles and track exceptions for follow-up.
+
+**Rationale**:
+- Preserves functional behavior while raising consistency quickly.
+- Supports FR-005/FR-006 in spec by preventing disruption of critical flows.
+- Makes scope and technical debt explicit.
+
+**Alternatives considered**:
+- Block release until 100% conformance (rejected: delays value delivery).
+- Ignore non-conformant areas (rejected: no governance and unresolved inconsistency).
+
+---
+
+## Decision 3: Canonical UX state patterns for loading/empty/error/success
+
+**Decision**: Define one reusable state pattern per state type (layout placement, message format, recovery action position) and apply to targeted modules.
+
+**Rationale**:
+- Directly supports UX reference and SC-003.
+- Improves predictability and user trust.
+- Simplifies QA with deterministic state contracts.
+
+**Alternatives considered**:
+- Module-specific state designs (rejected: reintroduces inconsistency).
+- Visual-only alignment without message/rule alignment (rejected: incomplete UX consistency).
+
+---
+
+## Decision 4: i18n and terminology normalization as part of style work
+
+**Decision**: Include text tone/terminology consistency in scope for user-facing state and action labels; avoid hardcoded strings during updates.
+
+**Rationale**:
+- Required by constitution i18n rule.
+- Prevents mixed terms after visual unification.
+- Supports FR-007 and UX tone requirements.
+
+**Alternatives considered**:
+- Deferring terminology to a separate feature (rejected: causes visible inconsistency after style updates).
+
+---
+
+## Decision 5: Accessibility-preserving visual alignment
+
+**Decision**: Keep focus visibility and readable contrast as non-negotiable constraints; when style and accessibility conflict, accessibility wins.
+
+**Rationale**:
+- Matches edge-case requirements in spec.
+- Reduces user risk and supports sustainable UI governance.
+- Prevents regressions masked by purely visual approvals.
+
+**Alternatives considered**:
+- Prioritizing strict visual sameness in all cases (rejected: can degrade accessibility outcomes).
+
+---
+
+## Decision 6: Verification model = conformance checklist + route smoke tests + UX state checks
+
+**Decision**: Validate through structured cross-route conformance checks, independent user-story tests, and targeted UX state verification.
+
+**Rationale**:
+- Produces measurable evidence for SC-001..SC-005.
+- Aligns with independent testability principle in constitution.
+- Keeps verification technology-agnostic at feature level while staying executable in project context.
+
+**Alternatives considered**:
+- Pure visual review without scenario checks (rejected: misses behavior regressions).
+- Full end-to-end redesign QA cycle before incremental rollout (rejected: too heavy for initial unification phase).

+# Feature Specification: Frontend Style Unification
+
+**Feature Branch**: `[001-unify-frontend-style]`  
+**Reference UX**: `[ux_reference.md]` (See specific folder)  
+**Created**: 2026-02-23  
+**Status**: Draft  
+**Input**: User description: "Даю тебе полный кардбланш на приведение фронтэнда к единому стилю. Прочитай .ai/ROOT.md, используй всю методологию workflow speckit при разработке. Вперед"
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Consistent Visual Foundation (Priority: P1)
+
+As a product user, I want all major screens and shared UI blocks to look and behave consistently so that the interface feels coherent and predictable.
+
+**Why this priority**: This is the core business value of the request. Without a shared visual baseline, every other UX improvement remains fragmented.
+
+**Independent Test**: Can be fully tested by opening key routes (dashboards, tasks, reports, settings) and confirming that shared UI primitives (spacing, typography hierarchy, cards, buttons, states) are visually consistent and predictable.
+
+**Acceptance Scenarios**:
+
+1. **Given** a user opens two different primary routes, **When** they compare page structure and shared controls, **Then** they see the same spacing rhythm, typography hierarchy, and interaction patterns.
+2. **Given** a user interacts with common controls (buttons, tabs, cards), **When** the controls are viewed across different pages, **Then** they have consistent style variants and state behavior.
+
+---
+
+### User Story 2 - Unified Navigation and Page Shells (Priority: P2)
+
+As a user navigating between sections, I want navigation, headers, and content shells to follow one pattern so that I can orient quickly and reduce navigation errors.
+
+**Why this priority**: Once visual foundation exists, navigation consistency delivers immediate usability gains and lowers cognitive load.
+
+**Independent Test**: Can be tested independently by traversing main navigation paths and confirming shell consistency (title placement, breadcrumbs behavior, action region layout, content container behavior).
+
+**Acceptance Scenarios**:
+
+1. **Given** a user switches between at least three top-level pages, **When** each page loads, **Then** page shell structure (title, context, actions, content container) follows one standard pattern.
+2. **Given** a user relies on breadcrumbs and navigation cues, **When** they move deeper and back in the hierarchy, **Then** navigation cues remain consistent and unambiguous.
+
+---
+
+### User Story 3 - Predictable Feedback and States (Priority: P3)
+
+As a user performing actions, I want loading, empty, success, and error states to be consistent across modules so that I always understand system status and next steps.
+
+**Why this priority**: Consistent state feedback improves trust and task completion, but can be delivered after foundational visual and navigation unification.
+
+**Independent Test**: Can be tested by triggering common states (loading data, empty results, validation errors, successful actions) on selected modules and verifying consistent tone, placement, and recovery guidance.
+
+**Acceptance Scenarios**:
+
+1. **Given** a user opens a page with delayed data, **When** loading is shown, **Then** loading indicators follow one standard style and placement pattern.
+2. **Given** a user encounters an empty or error state, **When** the state appears, **Then** the message format and recovery action style are consistent with other modules.
+
+---
+
+### Edge Cases
+
+- What happens when legacy components cannot be visually aligned without breaking current behavior?  
+  The system keeps behavior intact while applying the closest approved style fallback and records the component for deferred refinement.
+- How does system handle mixed localized text lengths affecting unified layout?  
+  Layout rules must preserve readability and alignment under longer labels and translated text.
+- What happens when a page includes highly custom data widgets that do not match standard containers?  
+  The page still applies shared shell and spacing rules while allowing controlled exceptions for specialized content blocks.
+- How does system handle accessibility-related differences (focus ring, contrast expectations) during unification?  
+  Accessibility-preserving variants take precedence over purely decorative alignment.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST define and apply a single frontend style baseline for typography hierarchy, spacing rhythm, color usage roles, and corner/radius behavior across primary user-facing pages.
+- **FR-002**: System MUST standardize shared component presentation patterns for page headers, cards, buttons, form sections, and content containers.
+- **FR-003**: Users MUST be able to navigate between core sections and observe consistent page shell structure, including title region, contextual navigation cues, and action placement.
+- **FR-004**: System MUST provide consistent state presentation rules for loading, empty, success, and error states in all targeted modules.
+- **FR-005**: System MUST preserve existing functional behavior while applying style unification; visual refactoring must not remove or alter core task flows.
+- **FR-006**: System MUST define explicit exception handling rules for modules/components that cannot fully conform immediately, including fallback styling and documented follow-up actions.
+- **FR-007**: System MUST align user-facing text tone and terminology in UI status messages to a unified voice and naming pattern.
+- **FR-008**: System MUST ensure unified styling remains compatible with existing localization and accessibility expectations (focus visibility, readable contrast, scalable layout for longer labels).
+
+### Key Entities *(include if feature involves data)*
+
+- **Style Token Group**: A logical definition of visual decisions (e.g., typography roles, spacing steps, semantic color roles, shape rules) used to enforce consistent appearance.
+- **UI Pattern Rule**: A reusable standard for structural or interaction patterns (e.g., page shell, action bar, card section, state message block).
+- **State Presentation Pattern**: A canonical rendering and messaging rule for loading, empty, success, and error states.
+- **Conformance Scope Item**: A mapped frontend area (route/component group) with current conformance status, expected target pattern, and exception note if needed.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: At least 90% of targeted primary frontend pages conform to the approved style baseline in a structured review checklist.
+- **SC-002**: Users can identify page title, navigation cue, and primary action location on targeted pages in under 5 seconds during UX validation walkthroughs.
+- **SC-003**: In cross-page UX review, at least 95% of sampled loading/empty/error/success states follow the same message and layout conventions.
+- **SC-004**: At least 80% of internal reviewers rate the updated UI as “visually consistent” or better after unification.
+- **SC-005**: No critical user flow regressions are introduced in the set of core routes covered by the style unification scope.

+## Phase 5: User Story 3 - Predictable Feedback and States (Priority: P3)
+
+**Goal**: Ensure loading/empty/error/success feedback is consistent in style, tone, and recovery guidance.
+
+**Independent Test**: Trigger state feedback on targeted modules and confirm canonical message/placement/recovery consistency.
+
+- [ ] T026 [US3] Implement canonical loading/empty/error/success blocks for reports experience in frontend/src/routes/reports/+page.svelte
+- [ ] T027 [US3] Implement canonical loading/empty/error/success blocks for tasks experience in frontend/src/routes/tasks/+page.svelte
+- [ ] T028 [US3] Align report detail feedback states to canonical patterns in frontend/src/lib/components/reports/ReportDetailPanel.svelte
+- [ ] T029 [P] [US3] Align report card status messaging and emphasis consistency in frontend/src/lib/components/reports/ReportCard.svelte
+- [ ] T030 [US3] Normalize user-facing status/recovery terminology via i18n keys in frontend/src/lib/i18n/locales/en.json
+- [ ] T031 [P] [US3] Normalize user-facing status/recovery terminology via i18n keys in frontend/src/lib/i18n/locales/ru.json
+- [ ] T032 [US3] Verify implementation matches ux_reference.md (Happy Path & Errors) in specs/001-unify-frontend-style/ux_reference.md
+
+---
+
+## Final Phase: Polish & Cross-Cutting Concerns
+
+- [ ] T033 Run route-level visual conformance walkthrough and update checklist in specs/001-unify-frontend-style/quickstart.md
+- [ ] T034 [P] Verify no critical flow regressions on dashboards/tasks/reports/settings in frontend/src/routes/dashboards/+page.svelte
+- [ ] T035 [P] Verify accessibility-visible focus/contrast constraints on updated components in frontend/src/lib/components/ui/Button.svelte
+- [ ] T036 Update deferred exceptions and follow-up actions in specs/001-unify-frontend-style/data-model.md
+- [ ] T037 Finalize implementation notes and readiness summary in specs/001-unify-frontend-style/plan.md
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- Setup (Phase 1) → required before Foundational (Phase 2)
+- Foundational (Phase 2) → required before all User Story phases
+- US1 (Phase 3) → MVP baseline
+- US2 (Phase 4) depends on foundational + US1 visual baseline
+- US3 (Phase 5) depends on foundational; can proceed after shell patterns are stable
+- Final Phase depends on completion of selected story scope
+
+### User Story Dependencies
+
+- **US1 (P1)**: Independent MVP slice
+- **US2 (P2)**: Builds on consistent primitives from US1
+- **US3 (P3)**: Can be implemented after foundational state blocks; best after US1/US2 alignment for consistency
+
+---
+
+## Parallel Execution Opportunities
+
+- T005, T006 can run in parallel after T004
+- T014 and T015 can run in parallel in US1
+- T022, T023, T024 can run in parallel in US2
+- T029, T031 can run in parallel in US3
+- T034 and T035 can run in parallel in Final Phase
+
+---
+
+## Implementation Strategy
+
+### MVP First (US1)
+
+1. Complete Phases 1–2
+2. Deliver US1 (consistent visual foundation) with T017 UX verification
+3. Validate quickstart conformance for core routes
+
+### Incremental Delivery
+
+1. Add US2 shell/navigation unification + T025 verification
+2. Add US3 feedback/state consistency + T032 verification
+3. Complete polish and final conformance/regression checks
+
+### Format Validation
+
+All tasks follow required checklist format:
+
+- `- [ ]`
+- Task ID (`Txxx`)
+- `[P]` marker only where parallelizable
+- `[USx]` label on user-story tasks
+- Explicit file path per task

+# UX Reference: Frontend Style Unification
+
+**Feature Branch**: `[001-unify-frontend-style]`
+**Created**: 2026-02-23
+**Status**: Draft
+
+## 1. User Persona & Context
+
+* **Who is the user?**: Product user and internal analyst who frequently switches between dashboards, tasks, reports, and settings.
+* **What is their goal?**: Complete routine operations quickly in a UI that feels consistent, predictable, and trustworthy.
+* **Context**: Browser-based multi-page workflow in the existing web frontend, often under time pressure, with repeated navigation between sections.
+
+## 2. The "Happy Path" Narrative
+
+The user opens the application and immediately recognizes where they are because every page has the same shell rhythm: clear title area, predictable action zone, and familiar content layout. As they move between dashboards, tasks, and reports, controls look and behave the same, so they do not need to relearn interactions. Loading and feedback states appear in the same visual language, which reduces hesitation and prevents mistakes. The overall experience feels coherent, fast to parse, and professionally maintained.
+
+## 3. Interface Mockups
+
+### UI Layout & Flow (if applicable)
+
+**Screen/Component**: Global Page Shell + Section Pages (Dashboards, Tasks, Reports)
+
+* **Layout**:
+  * Unified vertical rhythm for all primary pages.
+  * Consistent top shell: breadcrumb/context (when present), page title, page subtitle/helper text, actions region.
+  * Content area uses standardized containers/cards with the same spacing and header/body semantics.
+* **Key Elements**:
+  * **Primary Action Button**: Same visual hierarchy and placement rule in each section.
+  * **Secondary Actions**: Same grouping and alignment rules near the primary action.
+  * **Card Containers**: Same elevation/border/radius language and internal spacing.
+  * **State Blocks**: Loading, empty, success, and error states share one visual and textual pattern.
+* **States**:
+  * **Default**: Structured and clean; key action is easy to locate in <5 seconds.
+  * **Loading**: Placeholder/skeleton or loader appears in a consistent zone without layout jumps.
+  * **Success**: Confirmation message style is consistent in tone and placement.
+  * **Error**: Error state uses consistent emphasis and an immediate recovery action (e.g., retry).
+  * **Empty**: Neutral empty message with guidance on next action.
+
+## 4. The "Error" Experience
+
+**Philosophy**: Errors should be consistent, informative, and recovery-oriented—never dead ends.
+
+### Scenario A: Validation / Input Conflict
+
+* **User Action**: User applies an invalid filter or submits an incomplete form.
+* **System Response**:
+  * The problematic field/area is highlighted consistently across modules.
+  * A concise message explains what is wrong and what to do next.
+* **Recovery**: User can correct input in-place and retry immediately, without page reload.
+
+### Scenario B: Data Loading Failure
+
+* **User Action**: User opens a page and backend request fails.
+* **System Response**:
+  * A standardized error block appears in the content area.
+  * The message format is consistent with other modules.
+  * A clear recovery action is presented (e.g., "Retry").
+* **Recovery**: User retries from the same state; on success the page returns to normal layout without disorientation.
+
+## 5. Tone & Voice
+
+* **Style**: Concise, clear, and confidence-building.
+* **Terminology**: Use consistent terms across the product (e.g., one canonical term per concept), avoid mixed synonyms in state messages and actions.

+
+## Contract Usage Simulation (Key Scenario)
+
+Scenario traced: Operator finds failed migration quickly and triages.
+
+1. `UnifiedReportsPage` requests filtered list (`status=failed`, `task_type=migration`) through `ReportsApiClient`.
+2. `ReportsApiClient` calls `ReportsApiContract` list endpoint.
+3. `ReportsAggregationModule` normalizes task records and returns canonical report items.
+4. `UnifiedReportsPage` enters `Ready` `@UX_STATE`, rendering migration-specific visual profile.
+5. Operator opens one report detail.
+6. `ReportsApiContract` detail endpoint returns diagnostics + `next_actions`.
+7. UI shows actionable failure context and recovery guidance without changing page context.
+
+Continuity check: No interface mismatch found across contracts for list/filter/detail path.

+
+### Validation Rules
+
+- Detail view must always include `report`.
+- For `failed`/`partial` status, `next_actions` should be non-empty whenever actionable context exists.
+
+---
+
+## 6. Relationships
+
+- `ReportCollection.items[*]` → `TaskReport`
+- `TaskReport.task_type` → selects `ReportTypeProfile`

+# Implementation Plan: Unified Task Reports by Type
+
+**Branch**: `020-task-reports-design` | **Date**: 2026-02-22 | **Spec**: [`/home/busya/dev/ss-tools/specs/020-task-reports-design/spec.md`](specs/020-task-reports-design/spec.md)  
+**Input**: Feature specification from [`/specs/020-task-reports-design/spec.md`](specs/020-task-reports-design/spec.md)
+
+## Summary
+
+Implement a unified reports experience that aggregates task outcomes across LLM documentation/verification, backups, migrations, and documentation into one report center with type-specific visual design. The approach extends existing task/result data flows and adds normalized report-view contracts so users can identify type, status, and next actions quickly while preserving current async task architecture and operational observability.
+
+## Technical Context
+
+**Language/Version**: Python 3.9+ (backend), Node.js 18+ (frontend)  
+**Primary Dependencies**: FastAPI, SvelteKit, Tailwind CSS, SQLAlchemy/Pydantic task models, existing task/websocket stack  
+**Storage**: SQLite task/result persistence (existing task DB), filesystem only for existing artifacts (no new primary store required)  
+**Testing**: pytest (backend), Vitest (frontend), API contract tests for report endpoints  
+**Target Platform**: Linux server backend + browser-based SPA frontend  
+**Project Type**: Web application (frontend + backend)  
+**Performance Goals**: Report list first render <2s for typical workload; filter response perceived immediate (<500ms UI update for already loaded data)  
+**Constraints**: Must reuse existing TaskManager async model; no blocking task APIs; preserve RBAC boundaries; avoid breaking current dashboards/datasets/task pages  
+**Scale/Scope**: Unified view for at least 4 report types; thousands of historical report entries, with pagination/filtering in UX
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Gate | Status | Notes |
+|---|---|---|
+| Semantic Protocol Compliance ([`constitution.md`](.ai/standards/constitution.md)) | PASS | New/updated modules will define [DEF] contracts in [`contracts/modules.md`](specs/020-task-reports-design/contracts/modules.md). |
+| Modular Plugin Architecture | PASS | Feature consumes plugin/task outputs; no hardcoded config paths; existing config/dependency mechanisms retained. |
+| Unified Frontend Experience | PASS | Tailwind-first UI, reuse existing API wrappers, and route all user-facing strings through i18n files in implementation phase. |
+| Security & RBAC | PASS | Report visibility remains under existing auth/session and permission checks; no permission bypass in plan. |
+| Independent Testability | PASS | Spec already defines independent user stories and acceptance scenarios. |
+| Asynchronous Execution | PASS | Long-running operations remain task-based; reporting is read/aggregation over async outcomes. |

+
+**Structure Decision**: Use the existing web application split ([`backend/`](backend), [`frontend/`](frontend)) with feature additions in report-oriented API route/service and a dedicated frontend reports route/components. This minimizes architectural risk and conforms to existing module boundaries in [`PROJECT_MAP`](.ai/PROJECT_MAP.md).
+
+## Phase 0: Research Focus
+
+Research tasks derived from technical context and spec:
+
+1. Best strategy to normalize heterogeneous task outputs (LLM, backup, migration, documentation) into one report DTO without losing type-specific meaning.
+2. Pagination/filter tradeoffs for large report history while preserving UX scan speed from [`ux_reference.md`](specs/020-task-reports-design/ux_reference.md).
+3. Error/fallback taxonomy for unknown task type and partial payloads consistent with existing task status model.
+4. RBAC and privacy implications of consolidated cross-type reporting.
+5. Contract strategy for mapping UX states (Loading/Empty/FilteredEmpty/Error) to backend/frontend boundaries.
+
+## Phase 1: Design & Contracts Plan
+
+1. Validate architecture against UX:
+   - Ensure unified list + type-specific cards + fast filtering supports happy path.
+   - Ensure explicit handling for Loading/No Data/Filtered Empty/Failed report detail states.
+2. Produce [`data-model.md`](specs/020-task-reports-design/data-model.md) from spec entities and lifecycle rules.
+3. Produce [`contracts/modules.md`](specs/020-task-reports-design/contracts/modules.md) with DEF headers, TIER, PRE/POST, UX state tags where applicable.
+4. Simulate one full scenario through contracts (failed migration report discovery and triage path).
+5. Produce API contract at [`reports-api.openapi.yaml`](specs/020-task-reports-design/contracts/reports-api.openapi.yaml) for backend/frontend sync.
+6. Produce [`quickstart.md`](specs/020-task-reports-design/quickstart.md) for implementation and verification flow.
+7. Run agent context updater script and record result.
+
+## Complexity Tracking
+
+No constitution violations identified; section intentionally empty.

+## Test Data Reference
+
+| Component | TIER | Fixture Name | Location |
+|---|---|---|---|

+| Report Filtering & Discovery | STANDARD | failed_reports_filterable | [`spec.md`](specs/020-task-reports-design/spec.md) |
+
+**Note**: Tester implementation should materialize these fixtures in backend/frontend test suites during `/speckit.tasks` execution.

+# Quickstart: Unified Task Reports by Type
+
+## Purpose
+
+Implement and validate the unified reports feature defined in:
+- Spec: [`spec.md`](specs/020-task-reports-design/spec.md)
+- UX reference: [`ux_reference.md`](specs/020-task-reports-design/ux_reference.md)
+- Plan: [`plan.md`](specs/020-task-reports-design/plan.md)
+- Data model: [`data-model.md`](specs/020-task-reports-design/data-model.md)
+- Contracts: [`contracts/modules.md`](specs/020-task-reports-design/contracts/modules.md), [`contracts/reports-api.openapi.yaml`](specs/020-task-reports-design/contracts/reports-api.openapi.yaml)
+
+## 1) Backend implementation flow
+
+1. Add report API route module under existing API routes structure.
+2. Implement report aggregation/normalization service using canonical `TaskReport` envelope + type-specific details.
+3. Enforce server-side filtering and pagination according to OpenAPI contract.
+4. Ensure unknown task types map to fallback `unknown` and partial payloads are still returned.
+5. Keep read-only/non-blocking behavior for report endpoints.
+
+## 2) Frontend implementation flow
+
+1. Add unified reports page route and connect to existing API wrapper layer (no native fetch).
+2. Implement list view with type-specific visual profiles and explicit text labels.
+3. Implement filter toolbar (type/status/time/search) and empty/error/loading states.
+4. Add detail panel/page for selected report with diagnostics and next actions.
+5. Ensure all user-facing strings are i18n-ready.
+
+## 3) UX conformance checks (must pass)
+
+- Loading state shows skeleton placeholders.
+- No-data state appears when there are no reports at all.
+- Filtered-empty state appears for strict filter combinations and supports one-click clear.
+- Failed report shows clear reason + suggested next actions.
+- Unknown type is visible with neutral fallback style.
+
+## 4) Contract checks (must pass)
+
+- API payloads match [`reports-api.openapi.yaml`](specs/020-task-reports-design/contracts/reports-api.openapi.yaml).
+- Canonical minimum fields always present in list and detail.
+- Status and task_type values conform to enumerations.
+- Pagination metadata (`total`, `has_next`, `applied_filters`) is consistent.
+
+## 5) Suggested validation commands
+
+Backend tests (use project venv convention):
+```bash
+cd backend && .venv/bin/python3 -m pytest
+```
+
+Frontend tests:
+```bash
+cd frontend && npm test
+```
+
+Optional targeted API contract checks:
+```bash
+cd backend && .venv/bin/python3 -m pytest tests -k reports
+```
+
+## 6) Validation execution results (implementation run)
+
+### Backend targeted reports tests
+
+Command:
+```bash
+cd backend && .venv/bin/python3 -m pytest tests/test_reports_api.py tests/test_report_normalizer.py tests/test_reports_detail_api.py tests/test_reports_openapi_conformance.py -q
+```
+
+Result:
+- `tests/test_report_normalizer.py`: created and collected in run context.
+- API-level tests requiring app import failed at collection in current environment due DB connection:
+  - `psycopg2.OperationalError` / `sqlalchemy.exc.OperationalError`
+  - connection refused to `localhost:5432`
+
+Interpretation:
+- Reports code/tests are in place, but full backend validation in this environment is blocked by unavailable database service.
+- Re-run same command in environment with reachable DB to complete final verification.
+
+## 7) Done criteria for planning handoff
+
+- All planning artifacts exist and are internally consistent.
+- UX states in [`ux_reference.md`](specs/020-task-reports-design/ux_reference.md) are mapped in module contracts.
+- OpenAPI contract is stable for backend/frontend parallel implementation.
+- Ready to decompose into executable work items via `/speckit.tasks`.

+# Phase 0 Research: Unified Task Reports by Type
+
+**Feature**: [`020-task-reports-design`](specs/020-task-reports-design)  
+**Input Spec**: [`spec.md`](specs/020-task-reports-design/spec.md)  
+**Related UX**: [`ux_reference.md`](specs/020-task-reports-design/ux_reference.md)
+
+## 1) Normalizing heterogeneous task outputs into one report model
+
+### Decision
+Adopt a two-layer report model:
+1. **Canonical Report Envelope** shared across all task types.
+2. **Type-Specific Detail Block** preserved per task type (LLM verification/documentation, backup, migration, documentation).
+
+### Rationale
+This preserves a uniform list/filter/sort experience while avoiding data loss from specialized task outcomes. It also aligns with the spec’s requirement for consistent minimum fields and type-specific design.
+
+### Alternatives considered
+- **Single fully generic schema only**: rejected because rich type-specific context becomes flattened and less actionable.
+- **Separate endpoints and UI per type**: rejected because it breaks unified-report UX goal and increases navigation friction.
+
+---
+
+## 2) Pagination/filter strategy at report-history scale
+
+### Decision
+Use server-driven pagination and filtering as source of truth, with optional client-side refinement for currently visible page.
+
+### Rationale
+Large historical datasets require bounded payload sizes and stable response times. Server-side filtering supports scalable queries and predictable UX for “find failed report quickly” scenarios.
+
+### Alternatives considered
+- **Client-only filtering over full dataset**: rejected due to high transfer/memory cost and slow initial load at scale.
+- **Infinite scroll without explicit pagination metadata**: rejected due to weaker operational predictability and harder QA validation.
+
+---
+
+## 3) Unknown type and partial payload fallback semantics
+
+### Decision
+Define deterministic fallback rules:
+- Unknown type → render neutral “Other/Unknown” profile.
+- Missing fields → show explicit placeholder text (“Not provided”).
+- Status normalization maps all backend states into a fixed view state set: Success, Failed, In Progress, Partial.
+
+### Rationale
+This directly supports UX error-recovery expectations and prevents broken/blank interfaces when upstream task payloads vary.
+
+### Alternatives considered
+- **Hide malformed/unknown reports**: rejected because it reduces visibility and can hide operational incidents.
+- **Hard-fail rendering on missing fields**: rejected due to poor resilience and degraded operator trust.
+
+---
+
+## 4) RBAC/privacy in consolidated reporting
+
+### Decision
+Inherit existing task visibility and permission checks; do not broaden data exposure in this feature.
+
+### Rationale
+Consolidation can accidentally reveal cross-domain details. Reusing current auth boundaries avoids privilege escalation and keeps rollout low risk.
+
+### Alternatives considered
+- **Open read access to all reports**: rejected due to security/privacy risk.
+- **Introduce new role system in this feature**: rejected as out of scope and high change risk for current release.
+
+---
+
+## 5) UX state to contract mapping strategy
+
+### Decision
+Map UX states from [`ux_reference.md`](specs/020-task-reports-design/ux_reference.md) into explicit module/API contracts using semantic tags:
+- `@UX_STATE: Loading`
+- `@UX_STATE: NoData`
+- `@UX_STATE: FilteredEmpty`
+- `@UX_STATE: Error`
+- `@UX_STATE: Ready`
+
+### Rationale
+The project constitution and semantics standard require UX to be treated as contract logic, not decoration. Explicit state contracts reduce ambiguity for implementation and testing.
+
+### Alternatives considered
+- **Document states only in UX narrative**: rejected because it weakens enforceability and test traceability.
+- **Encode states implicitly in code without contracts**: rejected due to lower semantic compliance and harder review.
+
+---
+
+## Consolidated Research Outcomes for Planning
+
+- Canonical envelope + per-type details is the selected report modeling pattern.
+- Server-side pagination/filtering is required for scalable history.
+- Unknown/partial payloads must remain visible with fallback rendering.

+# Feature Specification: Unified Task Reports by Type
+
+**Feature Branch**: `020-task-reports-design`
+**Reference UX**: `ux_reference.md` (See specific folder)  
+**Created**: 2026-02-22  
+**Status**: Draft  
+**Input**: User description: "отображения отчетов по всем возможным задачам, со своим дизайном для каждого тип - llm документирование/проверка, бэкапы, миграции, документация."
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - View all task reports in one place (Priority: P1)
+
+As an operator, I can open a single reports area and see reports for all available task types so I do not need to switch between multiple sections to understand system outcomes.
+
+**Why this priority**: Centralized visibility is the core value; without it, the feature does not solve the reporting fragmentation problem.
+
+**Independent Test**: Can be fully tested by opening the reports area with a mixed set of task records and confirming each supported type appears in one consolidated list with clear type identification.
+
+**Acceptance Scenarios**:
+
+1. **Given** reports exist for LLM checks, backups, migrations, and documentation tasks, **When** the user opens the reports section, **Then** the system shows all report entries in a unified view.
+2. **Given** reports exist for only a subset of task types, **When** the user opens the reports section, **Then** the system still renders the available reports and clearly indicates missing types as empty or absent without errors.
+
+---
+
+### User Story 2 - Recognize report type by distinct design (Priority: P2)
+
+As an operator, I can visually distinguish report types by dedicated design patterns so I can quickly interpret what kind of task produced each report.
+
+**Why this priority**: Type-specific design significantly improves speed of reading and reduces interpretation errors, but is secondary to having all reports visible.
+
+**Independent Test**: Can be tested by rendering one report per supported type and validating that each type follows a unique, consistent visual style and label convention.
+
+**Acceptance Scenarios**:
+
+1. **Given** a report of type "LLM documentation/verification", **When** it is displayed, **Then** it uses the design variant defined for that type and includes explicit type labeling.
+2. **Given** a report of type "Backup", "Migration", or "Documentation", **When** each report is displayed, **Then** each uses its own dedicated design variant and remains visually distinguishable from others.
+
+---
+
+### User Story 3 - Understand report details and outcomes quickly (Priority: P3)
+
+As an operator, I can open a report and immediately see key outcome details (status, summary, timestamps, and relevant context) so I can decide what action is needed next.
+
+**Why this priority**: Rich report readability improves operational response quality after the core listing and type differentiation are available.
+
+**Independent Test**: Can be tested by opening reports with successful and failed outcomes and confirming key fields are consistently present and understandable across all types.
+
+**Acceptance Scenarios**:
+
+1. **Given** a successful report, **When** the user views its details, **Then** the report clearly presents completion status, summary, and execution time context.
+2. **Given** a failed or partial report, **When** the user views its details, **Then** the report clearly shows failure state, what failed, and actionable next-step guidance.
+
+---
+
+### Edge Cases
+
+- A report arrives with an unknown or newly added task type; the system shows it using a safe generic report design without breaking the reports page.
+- A task report exists but includes incomplete fields; the system displays available fields and explicit placeholders for missing values.
+- The number of reports is large; users can still locate relevant reports through clear ordering and filtering by type/status/time.
+- Multiple reports share the same timestamp; ordering remains stable and deterministic.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST provide one consolidated reports view containing report entries from all supported task types.
+- **FR-002**: System MUST support at minimum these report types as first-class categories: LLM documentation/verification, backup, migration, and documentation.
+- **FR-003**: System MUST assign and render a dedicated visual design profile for each supported report type.
+- **FR-004**: Users MUST be able to identify report type from both visual cues and explicit text labeling.
+- **FR-005**: System MUST display for every report a consistent minimum detail set: task type, execution status, completion or update time, and short summary.
+- **FR-006**: System MUST provide a detailed report view that includes outcome explanation and context needed for follow-up actions.
+- **FR-007**: System MUST represent report states consistently across all types using uniform semantics. Supported states MUST include: `success`, `failed`, `running`, `partial`, and `pending`.
+- **FR-008**: System MUST allow users to filter and group reports by type and status (e.g., grouping by date or type) to reduce time to find relevant items.
+- **FR-009**: System MUST handle missing or partial report data gracefully by showing fallback text rather than blank or broken UI.
+- **FR-010**: System MUST handle unsupported or unknown task types using a neutral fallback design that preserves visibility and readability.
+- **FR-011**: System MUST preserve report readability and usability when report volume grows (e.g., clear ordering and manageable navigation behavior).
+- **FR-012**: System MUST make error context visible for failed reports, including what failed and recovery-oriented guidance.
+
+### Key Entities *(include if feature involves data)*
+
+- **Task Report**: A user-visible summary of a task execution; key attributes include report identifier, task type, status, timestamps, summary, details, and severity/priority cues.
+- **Report Type Profile**: A definition of the visual and textual presentation rules for a report category; includes type label, style variant, iconography cues, and emphasis rules.
+- **Report Outcome**: A normalized status model for task results; includes state classification, message, error context (if any), and suggested next actions.
+- **Report Collection View**: An ordered and filterable set of task reports; includes active filters, sorting mode, and pagination or incremental loading state.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: 100% of reports belonging to the four target task types are visible from one unified reports entry point.
+- **SC-002**: In usability checks, at least 90% of users correctly identify report type within 3 seconds for each of the four target types.
+- **SC-003**: At least 90% of users can locate a failed report using type/status filtering in under 20 seconds.
+- **SC-004**: At least 95% of displayed reports include all required minimum fields (type, status, time, summary) without manual refresh or workaround.
+- **SC-005**: At least 85% of users report that report layouts are clear and visually distinct across task types.
+- **SC-006**: Support requests related to “where to find task results” decrease by at least 40% within one release cycle after launch.
+
+---
+
+## Assumptions
+
+- Existing task executions already produce reportable outcome data for the four target types.
+- Access permissions for viewing reports follow current user role rules and are not expanded in this feature.
+- Users primarily need read-oriented reporting with light interaction (view, filter, inspect details), not direct task execution from the reports screen.
+- A fallback presentation for unknown task types is acceptable and preferable to hiding reports.
+
+## Dependencies
+
+- Availability and consistency of report-producing task outputs across LLM documentation/verification, backup, migration, and documentation workflows.
+- Existing navigation path where users can access the unified reports section.
+- Agreed product design language that allows distinct but coherent type-based visual patterns.

+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- Phase 1 → no dependencies.
+- Phase 2 depends on Phase 1 and blocks all user stories.
+- Phase 3 (US1) depends on Phase 2.
+- Phase 4 (US2) depends on Phase 2; can proceed after US1 baseline route/list exists.
+- Phase 5 (US3) depends on Phase 2 and uses US1 list interaction.
+- Phase 6 depends on completion of selected user stories.
+
+### User Story Dependency Graph
+
+- **US1 (P1)**: first deliverable (MVP).
+- **US2 (P2)**: extends US1 presentation semantics.
+- **US3 (P3)**: extends US1 with detail drill-down and diagnostics.
+
+Graph: `US1 -> {US2, US3}`
+
+### Parallel Opportunities
+
+- Setup fixture/i18n tasks: T002, T003, T004.
+- Foundational tasks: T006 and T011 parallel with model scaffolding once T005 is done.
+- US1 tests T012/T013 in parallel.
+- US2 tests T020/T021 in parallel.
+- US3 tests T027/T028 and UI detail task T031 in parallel after endpoint contract is stable.
+- Cross-cutting checks T035/T036 parallel in Phase 6.
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+Task: "T012 [US1] Add backend contract tests in backend/src/api/routes/__tests__/test_reports_api.py"
+Task: "T013 [US1] Add frontend integration test in frontend/src/lib/components/reports/__tests__/reports_page.integration.test.js"
+
+Task: "T015 [US1] Implement reports route in frontend/src/routes/reports/+page.svelte"
+Task: "T016 [US1] Implement list component in frontend/src/lib/components/reports/ReportsList.svelte"
+```
+
+## Parallel Example: User Story 3
+
+```bash
+Task: "T027 [US3] Add backend detail contract tests in backend/src/api/routes/__tests__/test_reports_detail_api.py"
+Task: "T028 [US3] Add frontend detail integration test in frontend/src/lib/components/reports/__tests__/report_detail.integration.test.js"
+
+Task: "T030 [US3] Implement detail service assembly in backend/src/services/reports/report_service.py"
+Task: "T031 [US3] Implement report detail panel in frontend/src/lib/components/reports/ReportDetailPanel.svelte"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (Recommended)
+
+1. Complete Phase 1 + Phase 2.
+2. Complete Phase 3 (US1) and validate independent test.
+3. Demo/deploy MVP unified report list.
+
+### Incremental Delivery
+
+1. Add US2 for visual differentiation after MVP list stability.
+2. Add US3 for diagnostics/detail depth.
+3. Finish Phase 6 polish and conformance.
+
+### UX Preservation Rule
+
+No task in this plan intentionally degrades the UX defined in [`ux_reference.md`](specs/020-task-reports-design/ux_reference.md).  
+Each user story contains a mandatory UX verification task: T019, T026, T034.
