chore: add .gitattributes for text handling and line endings

- Removed redundant CSS rules and consolidated styles across dashboard, forms, imports, projects, and scenarios.
- Introduced new color variables in theme-default.css for better maintainability and consistency.
- Updated existing styles to utilize new color variables, enhancing the overall design.
- Improved responsiveness and layout of various components, including tables and cards.
- Ensured consistent styling for buttons, links, and headers across the application.

 ## Documentation & quickstart
 
-This repository contains only code. See detailed developer and architecture documentation in the [Docs](https://git.allucanget.biz/allucanget/calminer-docs) repository.
+- Detailed developer, architecture, and operations guides live in the companion [calminer-docs](../calminer-docs/) repository. Please see the [README](../calminer-docs/README.md) there for instructions.
+- For a local run, create a `.env` (see `.env.example`), install requirements, then execute `python -m scripts.init_db` followed by `uvicorn main:app --reload`. The initializer is safe to rerun and seeds demo data automatically.
+- To wipe and recreate the schema in development, run `CALMINER_ENV=development python -m scripts.reset_db` before invoking the initializer again.

 # Changelog
 
+## 2025-11-13
+
+- Completed the UI alignment initiative by consolidating shared form and button styles into `static/css/forms.css` and `static/css/main.css`, introducing the semantic palette in `static/css/theme-default.css`, and spot-checking key pages plus contrast reports.
+- Refactored the architecture data model docs by turning `calminer-docs/architecture/08_concepts/02_data_model.md` into a concise overview that links to new detail pages covering SQLAlchemy models, navigation metadata, enumerations, Pydantic schemas, and monitoring tables.
+- Nested the calculator navigation under Projects by updating `scripts/init_db.py` seeds, teaching `services/navigation.py` to resolve scenario-scoped hrefs for profitability/opex/capex, and extending sidebar coverage through `tests/integration/test_navigation_sidebar_calculations.py` plus `tests/services/test_navigation_service.py` to validate admin/viewer visibility and contextual URL generation.
+- Added navigation sidebar integration coverage by extending `tests/conftest.py` with role-switching headers, seeding admin/viewer test users, and adding `tests/integration/test_navigation_sidebar.py` to assert ordered link rendering for admins, viewer filtering of admin-only entries, and anonymous rejection of the endpoint.
+- Finalised the financial data import/export templates by inventorying required fields, defining CSV column specs with validation rules, drafting Excel workbook layouts, documenting end-user workflows in `calminer-docs/userguide/data_import_export.md`, and recording stakeholder review steps alongside updated TODO/DONE tracking.
+- Scoped profitability calculator UI under the scenario hierarchy by adding `/calculations/projects/{project_id}/scenarios/{scenario_id}/profitability` GET/POST handlers, updating scenario templates and sidebar navigation to link to the new route, and extending `tests/test_project_scenario_routes.py` with coverage for the scenario path plus legacy redirect behaviour (module run: 14 passed).
+- Extended scenario frontend regression coverage by updating `tests/test_project_scenario_routes.py` to assert project/scenario breadcrumbs and calculator navigation, normalising escaped URLs, and re-running the module tests (13 passing).
+- Cleared FastAPI and Pydantic deprecation warnings by migrating `scripts/init_db.py` to `@field_validator`, replacing the `main.py` startup hook with a lifespan handler, auditing template response call signatures, confirming HTTP 422 constant usage, and re-running the full pytest suite to ensure a clean warning slate.
+- Delivered the capex planner end-to-end: added scaffolded UI in `templates/scenarios/capex.html`, wired GET/POST handlers through `routes/calculations.py`, implemented calculation logic plus snapshot persistence in `services/calculations.py` and `models/capex_snapshot.py`, updated navigation links, and introduced unit tests in `tests/services/test_calculations_capex.py`.
+- Updated UI navigation to surface the opex planner by adding the sidebar link in `templates/partials/sidebar_nav.html`, wiring a scenario detail action in `templates/scenarios/detail.html`.
+- Completed manual validation of the Capex Planner UI flows (sidebar entry, scenario deep link, validation errors, successful calculation) with results captured in `manual_tests/capex.md`, documented snapshot verification steps, and noted the optional JSON client check for future follow-up.
+- Added opex calculation unit tests in `tests/services/test_calculations_opex.py` covering success metrics, currency validation, frequency enforcement, and evaluation horizon extension.
+- Documented the Opex Planner workflow in `calminer-docs/userguide/opex_planner.md`, linked it from the user guide index, extended `calminer-docs/architecture/08_concepts/02_data_model.md` with snapshot coverage, and captured the completion in `.github/instructions/DONE.md`.
+- Implemented opex integration coverage in `tests/integration/test_opex_calculations.py`, exercising HTML and JSON flows, verifying snapshot persistence, and asserting currency mismatch handling for form and API submissions.
+- Executed the full pytest suite with coverage (211 tests) to confirm no regressions or warnings after the opex documentation updates.
+- Completed the navigation sidebar API migration by finalising the database-backed service, refactoring `templates/partials/sidebar_nav.html` to consume the endpoint, hydrating via `static/js/navigation_sidebar.js`, and updating HTML route dependencies (`routes/projects.py`, `routes/scenarios.py`, `routes/reports.py`, `routes/imports.py`, `routes/calculations.py`) to use redirect-aware guards so anonymous visitors receive login redirects instead of JSON errors (manual verification via curl across projects, scenarios, reports, and calculations pages).
+
 ## 2025-11-12
 
+- Fixed critical 500 error in reporting dashboard by correcting route reference in reporting.html template - changed 'reports.project_list_page' to 'projects.project_list_page' to resolve NoMatchFound error when accessing /ui/reporting.
+- Completed navigation validation by inventorying all sidebar navigation links, identifying missing routes for simulations, reporting, settings, themes, and currencies, created new UI routes in routes/ui.py with proper authentication guards, built corresponding templates (simulations.html, reporting.html, settings.html, theme_settings.html, currencies.html), registered the UI router in main.py, updated sidebar navigation to use route names instead of hardcoded URLs, and enhanced navigation.js to use dynamic URL resolution for proper route handling.
+- Fixed critical template rendering error in sidebar_nav.html where URL objects from `request.url_for()` were being used with string methods, causing TypeError. Added `|string` filters to convert URL objects to strings for proper template rendering.
+- Integrated Plotly charting for interactive visualizations in reporting templates, added chart generation methods to ReportingService (`generate_npv_comparison_chart`, `generate_distribution_histogram`), updated project summary and scenario distribution contexts to include chart JSON data, enhanced templates with chart containers and JavaScript rendering, added chart-container CSS styling, and validated all reporting tests pass.
+
+- Completed local run verification: started application with `uvicorn main:app --reload` without errors, verified authenticated routes (/login, /, /projects/ui, /projects) load correctly with seeded data, and summarized findings for deployment pipeline readiness.
+- Fixed docker-compose.override.yml command array to remove duplicate "uvicorn" entry, enabling successful container startup with uvicorn reload in development mode.
+- Completed deployment pipeline verification: built Docker image without errors, validated docker-compose configuration, deployed locally with docker-compose (app and postgres containers started successfully), and confirmed application startup logs showing database bootstrap and seeded data initialization.
+- Completed documentation of current data models: updated `calminer-docs/architecture/08_concepts/02_data_model.md` with comprehensive SQLAlchemy model schemas, enumerations, Pydantic API schemas, and analysis of discrepancies between models and schemas.
 - Switched `models/performance_metric.py` to reuse the shared declarative base from `config.database`, clearing the SQLAlchemy 2.0 `declarative_base` deprecation warning and verifying repository tests still pass.
+- Replaced the Alembic migration workflow with the idempotent Pydantic-backed initializer (`scripts/init_db.py`), added a guarded reset utility (`scripts/reset_db.py`), removed migration artifacts/tooling (Alembic directory, config, Docker entrypoint), refreshed the container entrypoint to invoke `uvicorn` directly, and updated installation/architecture docs plus the README to direct developers to the new seeding/reset flow.
 - Eliminated Bandit hardcoded-secret findings by replacing literal JWT tokens and passwords across auth/security tests with randomized helpers drawn from `tests/utils/security.py`, ensuring fixtures still assert expected behaviours.
 - Centralized Bandit configuration in `pyproject.toml`, reran `bandit -c pyproject.toml -r calminer tests`, and verified the scan now reports zero issues.
-- Updated `.github/instructions/TODO.md` and `.github/instructions/DONE.md` to reflect the completed security scan remediation workflow.
 - Diagnosed admin bootstrap failure caused by legacy `roles` schema, added Alembic migration `20251112_00_add_roles_metadata_columns.py` to backfill `display_name`, `description`, `created_at`, and `updated_at`, and verified the migration via full pytest run in the activated `.venv`.
 - Resolved Ruff E402 warnings by moving module docstrings ahead of `from __future__ import annotations` across currency and pricing service modules, dropped the unused `HTTPException` import in `monitoring/__init__.py`, and confirmed a clean `ruff check .` run.
 - Enhanced the deploy job in `.gitea/workflows/cicache.yml` to capture Kubernetes pod, deployment, and container logs into `/logs/deployment/` for staging/production rollouts and publish them via a `deployment-logs` artifact, updating CI/CD documentation with retrieval instructions.
 - Fixed CI dashboard template lookup failures by renaming `templates/Dashboard.html` to `templates/dashboard.html` and verifying `tests/test_dashboard_route.py` locally to ensure TemplateNotFound no longer occurs on case-sensitive filesystems.
+- Implemented SQLite support as primary local database with environment-driven backend switching (`CALMINER_USE_SQLITE=true`), updated `scripts/init_db.py` for database-agnostic DDL generation (PostgreSQL enums vs SQLite CHECK constraints), tested compatibility with both backends, and verified application startup and seeded data initialization work seamlessly across SQLite and PostgreSQL.
 
 ## 2025-11-11
 
+- Collapsed legacy Alembic revisions into `alembic/versions/00_initial.py`, removed superseded migration files, and verified the consolidated schema via SQLite upgrade and Postgres version stamping.
 - Implemented base URL routing to redirect unauthenticated users to login and authenticated users to dashboard.
 - Added comprehensive end-to-end tests for login flow, including redirects, session handling, and error messaging for invalid/inactive accounts.
 - Updated header and footer templates to consistently use `logo_big.png` image instead of text logo, with appropriate CSS styling for sizing.
 - Centralised ISO-4217 currency validation across scenarios, imports, and export filters (`models/scenario.py`, `routes/scenarios.py`, `schemas/scenario.py`, `schemas/imports.py`, `services/export_query.py`) so malformed codes are rejected consistently at every entry point.
 - Updated scenario services and UI flows to surface friendly validation errors and added regression coverage for imports, exports, API creation, and lifecycle flows ensuring currencies are normalised end-to-end.
-- Recorded the completed “Ensure currency is used consistently” work in `.github/instructions/DONE.md` and ran the full pytest suite (150 tests) to verify the refactor.
 - Linked projects to their pricing settings by updating SQLAlchemy models, repositories, seeding utilities, and migrations, and added regression tests to cover the new association and default backfill.
 - Bootstrapped database-stored pricing settings at application startup, aligned initial data seeding with the database-first metadata flow, and added tests covering pricing bootstrap creation, project assignment, and idempotency.
 - Extended pricing configuration support to prefer persisted metadata via `dependencies.get_pricing_metadata`, added retrieval tests for project/default fallbacks, and refreshed docs (`calminer-docs/specifications/price_calculation.md`, `pricing_settings_data_model.md`) to describe the database-backed workflow and bootstrap behaviour.
