-## Key UI/UX Features
-
-- **Unified UI Shell**: Server-rendered templates extend a shared base layout with a persistent left sidebar linking scenarios, parameters, costs, consumption, production, equipment, maintenance, simulations, and reporting views.
-- **Modular Frontend Scripts**: Page-specific interactions in `static/js/` modules, keeping templates lean while enabling browser caching and reuse.
-
-## Planned Features
-
-See [Roadmap](docs/roadmap.md) for details on planned features and enhancements.
-
 ## Documentation & quickstart
 
-This repository contains detailed developer and architecture documentation in the `docs/` folder.
+This repository contains only code. See detailed developer and architecture documentation in the [Docs](https://git.allucanget.biz/allucanget/calminer-docs) repository.
-
-### Settings overview
-
-The Settings page (`/ui/settings`) lets administrators adjust global theme colors stored in the `application_setting` table. Changes are instantly applied across the UI. Environment variables prefixed with `CALMINER_THEME_` (for example, `CALMINER_THEME_COLOR_PRIMARY`) automatically override individual CSS variables and render as read-only in the form, ensuring deployment-time overrides take precedence while remaining visible to operators.
-
-[Quickstart](docs/quickstart.md) contains developer quickstart, migrations, testing and current status.
-
-Key architecture documents: see [architecture](docs/architecture/README.md) for the arc42-based architecture documentation.
-
-For contributors: the `routes/`, `models/` and `services/` folders contain the primary application code. Tests and E2E specs are in `tests/`.
-
-## Run with Docker
-
-The repository ships with a multi-stage `Dockerfile` that produces a slim runtime image.
-
-### Build container
-
-```bash
-docker build -t calminer .
-```
-
-### Push to registry
-
-To push the image to a registry, tag it appropriately and push:
-
-```bash
-docker tag calminer your-registry/calminer:latest
-docker push your-registry/calminer:latest
-```
-
-### Run container
-
-To run the container, ensure PostgreSQL is available and set environment variables:
-
-```bash
-docker run -p 8000:8000 \
-  -e DATABASE_HOST=your-postgres-host \
-  -e DATABASE_PORT=5432 \
-  -e DATABASE_USER=calminer \
-  -e DATABASE_PASSWORD=your-password \
-  -e DATABASE_NAME=calminer_db \
-  calminer
-```
-
-## Development with Docker Compose
-
-For local development, use `docker-compose.yml` which includes the app and PostgreSQL services.
-
-```bash
-# Start services
-docker-compose up
-
-# Or run in background
-docker-compose up -d
-
-# Stop services
-docker-compose down
-```
-
-The app will be available at `http://localhost:8000`, PostgreSQL at `localhost:5432`.
-
-## CI/CD
-
-CalMiner uses Gitea Actions workflows stored in `.gitea/workflows/`:
-
-- `ci.yml`: Runs on push and PR to main/develop branches. Sets up Python, installs dependencies, runs tests with coverage, and builds the Docker image.

-# 01 — Introduction and Goals
-
-## Purpose
-
-CalMiner aims to provide a comprehensive platform for mining project scenario analysis, enabling stakeholders to make informed decisions based on data-driven insights.
-
-## Stakeholders
-
-- **Project Managers**: Require tools for scenario planning and risk assessment.
-- **Data Analysts**: Need access to historical data and simulation results for analysis.
-- **Executives**: Seek high-level insights and reporting for strategic decision-making.
-
-## High-Level Goals
-
-1. **Comprehensive Scenario Analysis**: Enable users to create and analyze multiple project scenarios to assess risks and opportunities.
-2. **Data-Driven Decision Making**: Provide stakeholders with the insights needed to make informed decisions based on simulation results.
-3. **User-Friendly Interface**: Ensure the platform is accessible and easy to use for all stakeholders, regardless of technical expertise.
-
-## System Overview
-
-FastAPI application that collects mining project inputs, persists scenario-specific records, and surfaces aggregated insights. The platform targets Monte Carlo driven planning, with deterministic CRUD features in place and simulation logic staged for future work.
-
-Frontend components are server-rendered Jinja2 templates, with Chart.js powering the dashboard visualization. The backend leverages SQLAlchemy for ORM mapping to a PostgreSQL database.
-
-### Runtime Flow
-
-1. Users navigate to form templates or API clients to manage scenarios, parameters, and operational data.
-2. FastAPI routers validate payloads with Pydantic models, then delegate to SQLAlchemy sessions for persistence.
-3. Simulation runs (placeholder `services/simulation.py`) will consume stored parameters to emit iteration results via `/api/simulations/run`.
-4. Reporting requests POST simulation outputs to `/api/reporting/summary`; the reporting service calculates aggregates (count, min/max, mean, median, percentiles, standard deviation, variance, and tail-risk metrics at the 95% confidence level).
-5. `templates/Dashboard.html` fetches summaries, renders metric cards, and plots distribution charts with Chart.js for stakeholder review.
-
-### Current implementation status (summary)
-
-- Currency normalization, simulation scaffold, and reporting service exist; see [quickstart](../quickstart.md) for full status and migration instructions.
-
-## MVP Features (migrated)
-
-The following MVP features and priorities were defined during initial planning.
-
-### Prioritized Features
-
-1. **Scenario Creation and Management** (High Priority): Allow users to create, edit, and delete scenarios. Rationale: Core functionality for what-if analysis.
-1. **Parameter Input and Validation** (High Priority): Input process parameters with validation. Rationale: Ensures data integrity for simulations.
-1. **Monte Carlo Simulation Run** (High Priority): Execute simulations and store results. Rationale: Key differentiator for risk analysis.
-1. **Basic Reporting** (Medium Priority): Display NPV, IRR, EBITDA from simulation results. Rationale: Essential for decision-making.
-1. **Cost Tracking Dashboard** (Medium Priority): Visualize CAPEX and OPEX. Rationale: Helps monitor expenses.
-1. **Consumption Monitoring** (Low Priority): Track resource consumption. Rationale: Useful for optimization.
-1. **User Authentication** (Medium Priority): Basic login/logout. Rationale: Security for multi-user access.
-1. **Export Results** (Low Priority): Export simulation data to CSV/PDF. Rationale: For external analysis.
-
-### Rationale for Prioritization
-
-- High: Core simulation and scenario features first.
-- Medium: Reporting and auth for usability.
-- Low: Nice-to-haves after basics.

-# Technical Constraints
-
-> e.g., choice of FastAPI, PostgreSQL, SQLAlchemy, Chart.js, Jinja2 templates.
-
-The architecture of CalMiner is influenced by several technical constraints that shape its design and implementation:
-
-1. **Framework Selection**: The choice of FastAPI as the web framework imposes constraints on how the application handles requests, routing, and middleware. FastAPI's asynchronous capabilities must be leveraged appropriately to ensure optimal performance.
-2. **Database Technology**: The use of PostgreSQL as the primary database system dictates the data modeling, querying capabilities, and transaction management strategies. SQLAlchemy ORM is used for database interactions, which requires adherence to its conventions and limitations.
-3. **Frontend Technologies**: The decision to use Jinja2 for server-side templating and Chart.js for data visualization influences the structure of the frontend code and the way dynamic content is rendered.

-
-## Customization
-
-### Environment Variables
-
-Theme colors can be overridden using environment variables with the prefix `CALMINER_THEME_`. For example:
-
-```bash
-export CALMINER_THEME_COLOR_BACKGROUND="#000000"
-export CALMINER_THEME_COLOR_ACCENT="#ff0000"
-```
-
-The variable names are derived by:
-
-1. Removing the `--` prefix
-2. Converting to uppercase
-3. Replacing `-` with `_`
-4. Adding `CALMINER_THEME_` prefix
-
-### Database Storage
-
-Settings are stored in the `application_setting` table with:
-
-- `category`: "theme"
-- `value_type`: "color"
-- `is_editable`: true
-
-### UI Settings
-
-Users can modify theme colors through the settings page at `/ui/settings`.
-
-## Implementation
-
-The theming system is implemented in:
-
-- `services/settings.py`: Color management and defaults
-- `routes/settings.py`: API endpoints for theme settings
-- `static/css/main.css`: CSS variable definitions
-- `templates/settings.html`: UI for theme customization
-
-## Seeding
-
-Default theme settings are seeded during database setup using the seed script:
-
-```bash
-python scripts/seed_data.py --theme
-```
-
-Or as part of defaults:
-
-```bash
-python scripts/seed_data.py --defaults
-```

-# 06 — Runtime View
-
-## Overview
-
-The runtime view focuses on the dynamic behavior of the CalMiner application during execution. It illustrates how various components interact to fulfill user requests, process data, and generate outputs. Key runtime scenarios include scenario management, parameter input handling, cost tracking, consumption tracking, production output recording, equipment management, maintenance logging, Monte Carlo simulations, and reporting.
-
-## Request Flow
-
-1. **User Interaction**: A user interacts with the web application through the UI, triggering actions such as creating a scenario, inputting parameters, or generating reports.
-2. **API Request**: The frontend sends HTTP requests (GET, POST, PUT, DELETE) to the appropriate API endpoints defined in the `routes/` directory.
-3. **Routing**: The FastAPI framework routes the incoming requests to the corresponding route handlers.
-4. **Service Layer**: Route handlers invoke services from the `services/` directory to process the business logic.
-5. **Database Interaction**: Services interact with the database via ORM models defined in the `models/` directory to perform CRUD operations.
-6. **Response Generation**: After processing, services return data to the route handlers, which format the response (JSON or HTML) and send it back to the frontend.
-7. **UI Update**: The frontend updates the UI based on the response, rendering new data or updating existing views.
-8. **Reporting Pipeline**: For reporting, data is aggregated from various sources, processed to generate statistics, and presented in the dashboard using Chart.js.
-9. **Monte Carlo Simulations**: Stochastic simulations are executed in the backend, generating probabilistic outcomes that are stored temporarily and used for risk analysis in reports.
-10. **Error Handling**: Throughout the process, error handling mechanisms ensure that exceptions are caught and appropriate responses are sent back to the user.

-
-### Cost Tracking
-
-1. User accesses the cost tracking view.
-2. The frontend sends a GET request to `/api/costs` to fetch existing cost records.
-3. The `CostService` retrieves cost data from the database.
-4. The response is rendered in the UI.
-5. For cost updates, the user submits a form, triggering a PUT request to `/api/costs/:id`, which the `CostService` processes to update the cost record in the database.
-6. The UI updates to reflect the changes.

-
-## Reporting Pipeline and UI Integration
-
-1. **Data Sources**
-
-   - Scenario-linked calculations (costs, consumption, production) produce raw figures stored in dedicated tables (`capex`, `opex`, `consumption`, `production_output`).
-   - Monte Carlo simulations (currently transient) generate arrays of `{ "result": float }` tuples that the dashboard or downstream tooling passes directly to reporting endpoints.
-
-2. **API Contract**
-
-   - `POST /api/reporting/summary` accepts a JSON array of result objects and validates shape through `_validate_payload` in `routes/reporting.py`.
-   - On success it returns a structured payload (`ReportSummary`) containing count, mean, median, min/max, standard deviation, and percentile values, all as floats.
-
-3. **Service Layer**
-
-   - `services/reporting.generate_report` converts the sanitized payload into descriptive statistics using Python’s standard library (`statistics` module) to avoid external dependencies.
-   - The service remains stateless; no database read/write occurs, which keeps summary calculations deterministic and idempotent.
-   - Extended KPIs (surfaced in the API and dashboard):
-     - `variance`: population variance computed as the square of the population standard deviation.
-     - `percentile_5` and `percentile_95`: lower and upper tail interpolated percentiles for sensitivity bounds.
-     - `value_at_risk_95`: 5th percentile threshold representing the minimum outcome within a 95% confidence band.
-     - `expected_shortfall_95`: mean of all outcomes at or below the `value_at_risk_95`, highlighting tail exposure.
-
-4. **UI Consumption**
-
-   - `templates/Dashboard.html` posts the user-provided dataset to the summary endpoint, renders metric cards for each field, and charts the distribution using Chart.js.
-   - `SUMMARY_FIELDS` now includes variance, 5th/10th/90th/95th percentiles, and tail-risk metrics (VaR/Expected Shortfall at 95%); tooltip annotations surface the tail metrics alongside the percentile line chart.
-   - Error handling surfaces HTTP failures inline so users can address malformed JSON or backend availability issues without leaving the page.

-
-## Monte Carlo Simulation Execution
-
-1. User initiates a Monte Carlo simulation via the UI.
-2. The frontend sends a POST request to `/api/simulations/run` with simulation parameters.
-3. The `SimulationService` executes the Monte Carlo logic, generating stochastic results.
-4. The results are temporarily stored and returned to the frontend.
-5. The UI displays the simulation results and allows users to trigger reporting based on these outcomes.
-6. The reporting pipeline processes the simulation results as described above.
-7. Error handling ensures that any issues during simulation execution are communicated back to the user.

-
-## Error Handling
-
-Throughout the runtime processes, error handling mechanisms are implemented to catch exceptions and provide meaningful feedback to users. Common error scenarios include:
-
-- Invalid input data
-- Database connection issues
-- Simulation execution errors
-- Reporting calculation failures
-- API endpoint unavailability
-- Timeouts during long-running operations
-- Unauthorized access attempts
-- Data validation failures
-- Resource not found errors

-# Testing, CI and Quality Assurance
-
-This chapter centralizes the project's testing strategy, CI configuration, and quality targets.
-
-## Overview
-
-CalMiner uses a combination of unit, integration, and end-to-end tests to ensure quality.
-
-### Frameworks
-
-- Backend: pytest for unit and integration tests.
-- Frontend: pytest with Playwright for E2E tests.
-- Database: pytest fixtures with psycopg2 for DB tests.
-
-### Test Types
-
-- Unit Tests: Test individual functions/modules.
-- Integration Tests: Test API endpoints and DB interactions.
-- E2E Tests: Playwright for full user flows.
-
-### CI/CD
-
-- Use Gitea Actions for CI/CD; workflows live under `.gitea/workflows/`.
-- `ci.yml` runs on push and pull requests to `main` and `develop` branches. It provisions a temporary PostgreSQL 15 service, sets up Python 3.11, installs dependencies from `requirements.txt` and `requirements-test.txt`, runs pytest with coverage on all tests, and builds the Docker image.
-- Run tests on pull requests to shared branches; enforce coverage target ≥80% (pytest-cov).
-
-### Running Tests
-
-- Unit: `pytest tests/unit/`
-- E2E: `pytest tests/e2e/`
-- All: `pytest`
-
-### Test Directory Structure
-
-Organize tests under the `tests/` directory mirroring the application structure:
-
-```text
-tests/
-  unit/
-    test_<module>.py
-  e2e/
-    test_<flow>.py
-  fixtures/
-    conftest.py
-```
-
-### Fixtures and Test Data
-
-- Define reusable fixtures in `tests/fixtures/conftest.py`.
-- Use temporary in-memory databases or isolated schemas for DB tests.
-- Load sample data via fixtures for consistent test environments.
-- Leverage the `seeded_ui_data` fixture in `tests/unit/conftest.py` to populate scenarios with related cost, maintenance, and simulation records for deterministic UI route checks.
-
-### E2E (Playwright) Tests
-
-The E2E test suite, located in `tests/e2e/`, uses Playwright to simulate user interactions in a live browser environment. These tests are designed to catch issues in the UI, frontend-backend integration, and overall application flow.
-
-#### Fixtures
-
-- `live_server`: A session-scoped fixture that launches the FastAPI application in a separate process, making it accessible to the browser.
-- `playwright_instance`, `browser`, `page`: Standard `pytest-playwright` fixtures for managing the Playwright instance, browser, and individual pages.
-
-#### Smoke Tests
-
-- UI Page Loading: `test_smoke.py` contains a parameterized test that systematically navigates to all UI routes to ensure they load without errors, have the correct title, and display a primary heading.
-- Form Submissions: Each major form in the application has a corresponding test file (e.g., `test_scenarios.py`, `test_costs.py`) that verifies: page loads, create item by filling the form, success message, and UI updates.
-
-### Running E2E Tests
-
-To run the Playwright tests:
-
-```bash
-pytest tests/e2e/
-```
-
-To run headed mode:
-
-```bash
-pytest tests/e2e/ --headed
-```
-
-### Mocking and Dependency Injection
-
-- Use `unittest.mock` to mock external dependencies.
-- Inject dependencies via function parameters or FastAPI's dependency overrides in tests.
-
-### Code Coverage
-
-- Install `pytest-cov` to generate coverage reports.
-- Run with coverage: `pytest --cov --cov-report=term` (use `--cov-report=html` when visualizing hotspots).
-- Target 95%+ overall coverage. Focus on historically low modules: `services/simulation.py`, `services/reporting.py`, `middleware/validation.py`, and `routes/ui.py`.
-- Latest snapshot (2025-10-21): `pytest --cov=. --cov-report=term-missing` returns **91%** overall coverage.
-
-### CI Integration
-
-`test.yml` encapsulates the steps below:
-
-- Check out the repository and set up Python 3.10.
-- Configure the runner's apt proxy (if available), install project dependencies (requirements + test extras), and download Playwright browsers.
-- Run `pytest` (extend with `--cov` flags when enforcing coverage).
-
-> The pip cache step is temporarily disabled in `test.yml` until the self-hosted cache service is exposed (see `docs/ci-cache-troubleshooting.md`).
-
-`build-and-push.yml` adds:
-
-- Registry login using repository secrets.
-- Docker image build/push with GHA cache storage (`cache-from/cache-to` set to `type=gha`).
-
-`deploy.yml` handles:
-
-- SSH into the deployment host.
-- Pull the tagged image from the registry.
-- Stop, remove, and relaunch the `calminer` container exposing port 8000.
-
-When adding new workflows, mirror this structure to ensure secrets, caching, and deployment steps remain aligned with the production environment.
-
-## Workflow Optimization Opportunities
-
-### `test.yml`
-
-- Run the apt-proxy setup once via a composite action or preconfigured runner image if additional matrix jobs are added.
-- Collapse dependency installation into a single `pip install -r requirements-test.txt` call (includes base requirements) once caching is restored.
-- Investigate caching or pre-baking Playwright browser binaries to eliminate >650 MB cold downloads per run.
-
-### `build-and-push.yml`
-
-- Skip QEMU setup or explicitly constrain Buildx to linux/amd64 to reduce startup time.
-- Enable `cache-from` / `cache-to` settings (registry or `type=gha`) to reuse Docker build layers between runs.
-
-### `deploy.yml`
-
-- Extract deployment script into a reusable shell script or compose file to minimize inline secrets and ease multi-environment scaling.
-- Add a post-deploy health check (e.g., `curl` readiness probe) before declaring success.
-
-### Priority Overview
-
-1. Restore shared caching for Python wheels and Playwright browsers once infrastructure exposes the cache service (highest impact on runtime and bandwidth; requires coordination with CI owners).
-2. Enable Docker layer caching in `build-and-push.yml` to shorten build cycles (medium effort, immediate benefit to release workflows).
-3. Add post-deploy health verification to `deploy.yml` (low effort, improves confidence in automation).
-4. Streamline redundant setup steps in `test.yml` (medium effort once cache strategy is in place; consider composite actions or base image updates).
-
-### Setup Consolidation Opportunities
-
-- `Run Tests` matrix jobs each execute the apt proxy configuration, pip installs, database wait, and setup scripts. A composite action or shell script wrapper could centralize these routines and parameterize target-specific behavior (unit vs e2e) to avoid copy/paste maintenance as additional jobs (lint, type check) are introduced.
-- Both the test and build workflows perform a `checkout` step; while unavoidable per workflow, shared git submodules or sparse checkout rules could be encapsulated in a composite action to keep options consistent.
-- The database setup script currently runs twice (dry-run and live) for every matrix leg. Evaluate whether the dry-run remains necessary once migrations stabilize; if retained, consider adding an environment variable toggle to skip redundant seed operations for read-only suites (e.g., lint).
-
-### Proposed Shared Setup Action
-
-- Location: `.gitea/actions/setup-python-env/action.yml` (composite action).
-- Inputs:
-  - `python-version` (default `3.10`): forwarded to `actions/setup-python`.
-  - `install-playwright` (default `false`): when `true`, run `python -m playwright install --with-deps`.
-  - `install-requirements` (default `requirements.txt requirements-test.txt`): space-delimited list pip installs iterate over.
-  - `run-db-setup` (default `true`): toggles database wait + setup scripts.
-  - `db-dry-run` (default `true`): controls whether the dry-run invocation executes.
-- Steps encapsulated:
-  1. Set up Python via `actions/setup-python@v5` using provided version.
-  2. Configure apt proxy via shared shell snippet (with graceful fallback when proxy offline).
-  3. Iterate over requirement files and execute `pip install -r <file>`.
-  4. If `install-playwright == true`, install browsers.
-  5. If `run-db-setup == true`, run the wait-for-Postgres python snippet and call `scripts/setup_database.py`, honoring `db-dry-run` toggle.
-- Usage sketch (in `test.yml`):
-
-```yaml
-- name: Prepare Python environment
-  uses: ./.gitea/actions/setup-python-env
-  with:
-    install-playwright: ${{ matrix.target == 'e2e' }}
-    db-dry-run: true
-```
-
-- Benefits: centralizes proxy logic and dependency installs, reduces duplication across matrix jobs, and keeps future lint/type-check jobs lightweight by disabling database setup.
-- Implementation status: action available at `.gitea/actions/setup-python-env` and consumed by `test.yml`; extend to additional workflows as they adopt the shared routine.
-- Obsolete steps removed: individual apt proxy, dependency install, Playwright, and database setup commands pruned from `test.yml` once the composite action was integrated.
-
-## CI Owner Coordination Notes
-
-### Key Findings
-
-- Self-hosted runner: ASUS System Product Name chassis with AMD Ryzen 7 7700X (8 physical cores / 16 threads) and 63.2 GB usable RAM; `act_runner` configuration not overridden, so only one workflow job runs concurrently today.
-- Unit test matrix job: completes 117 pytest cases in roughly 4.1 seconds after Postgres spins up; Docker services consume ~150 MB for `postgres:16-alpine`, with minimal sustained CPU load once tests begin.
-- End-to-end matrix job: `pytest tests/e2e` averages 21‑22 seconds of execution, but a cold run downloads ~179 MB of apt packages plus ~470 MB of Playwright browser bundles (Chromium, Firefox, WebKit, FFmpeg), exceeding 650 MB network transfer and adding several gigabytes of disk writes if caches are absent.
-- Both jobs reuse existing Python package caches when available; absent a shared cache service, repeated Playwright installs remain the dominant cost driver for cold executions.
-
-### Open Questions
-
-- Can we raise the runner concurrency above the default single job, or provision an additional runner, so the test matrix can execute without serializing queued workflows?
-- Is there a central cache or artifact service available for Python wheels and Playwright browser bundles to avoid ~650 MB downloads on cold starts?
-- Are we permitted to bake Playwright browsers into the base runner image, or should we pursue a shared cache/proxy solution instead?
-
-### Outreach Draft
-
-```text
-Subject: CalMiner CI parallelization support
-
-Hi <CI Owner>,
-
-We recently updated the CalMiner test workflow to fan out unit and Playwright E2E suites in parallel. While validating the change, we gathered the following:
-
-- Runner host: ASUS System Product Name with AMD Ryzen 7 7700X (8 cores / 16 threads), ~63 GB RAM, default `act_runner` concurrency (1 job at a time).
-- Unit job finishes in ~4.1 s once Postgres is ready; light CPU and network usage.
-- E2E job finishes in ~22 s, but a cold run pulls ~179 MB of apt packages plus ~470 MB of Playwright browser payloads (>650 MB download, several GB disk writes) because we do not have a shared cache yet.
-
-To move forward, could you help with the following?
-
-1. Confirm whether we can raise the runner concurrency limit or provision an additional runner so parallel jobs do not queue behind one another.
-2. Let us know if a central cache (Artifactory, Nexus, etc.) is available for Python wheels and Playwright browser bundles, or if we should consider baking the browsers into the runner image instead.
-3. Share any guidance on preferred caching or proxy solutions for large binary installs on self-hosted runners.
-
-Once we have clarity, we can finalize the parallel rollout and update the documentation accordingly.
-
-Thanks,
-<Your Name>

-# Database Deployment
-
-## Migrations & Baseline
-
-A consolidated baseline migration (`scripts/migrations/000_base.sql`) captures all schema changes required for a fresh installation. The script is idempotent: it creates the `currency` and `measurement_unit` reference tables, provisions the `application_setting` store for configurable UI/system options, ensures consumption and production records expose unit metadata, and enforces the foreign keys used by CAPEX and OPEX.
-
-Configure granular database settings in your PowerShell session before running migrations:
-
-```powershell
-$env:DATABASE_DRIVER = 'postgresql'
-$env:DATABASE_HOST = 'localhost'
-$env:DATABASE_PORT = '5432'
-$env:DATABASE_USER = 'calminer'
-$env:DATABASE_PASSWORD = 's3cret'
-$env:DATABASE_NAME = 'calminer'
-$env:DATABASE_SCHEMA = 'public'
-python scripts/setup_database.py --run-migrations --seed-data --dry-run
-python scripts/setup_database.py --run-migrations --seed-data
-```
-
-The dry-run invocation reports which steps would execute without making changes. The live run applies the baseline (if not already recorded in `schema_migrations`) and seeds the reference data relied upon by the UI and API.
-
-> ℹ️ When `--seed-data` is supplied without `--run-migrations`, the bootstrap script automatically applies any pending SQL migrations first so the `application_setting` table (and future settings-backed features) are present before seeding.
->
-> ℹ️ The application still accepts `DATABASE_URL` as a fallback if the granular variables are not set.
-
-## Database bootstrap workflow
-
-Provision or refresh a database instance with `scripts/setup_database.py`. Populate the required environment variables (an example lives at `config/setup_test.env.example`) and run:
-
-```powershell
-# Load test credentials (PowerShell)
-Get-Content .\config\setup_test.env.example |
-  ForEach-Object {
-    if ($_ -and -not $_.StartsWith('#')) {
-      $name, $value = $_ -split '=', 2
-      Set-Item -Path Env:$name -Value $value
-    }
-  }
-
-# Dry-run to inspect the planned actions
-python scripts/setup_database.py --ensure-database --ensure-role --ensure-schema --initialize-schema --run-migrations --seed-data --dry-run -v
-
-# Execute the full workflow
-python scripts/setup_database.py --ensure-database --ensure-role --ensure-schema --initialize-schema --run-migrations --seed-data -v
-```
-
-Typical log output confirms:
-
-- Admin and application connections succeed for the supplied credentials.
-- Database and role creation are idempotent (`already present` when rerun).
-- SQLAlchemy metadata either reports missing tables or `All tables already exist`.
-- Migrations list pending files and finish with `Applied N migrations` (a new database reports `Applied 1 migrations` for `000_base.sql`).
-
-After a successful run the target database contains all application tables plus `schema_migrations`, and that table records each applied migration file. New installations only record `000_base.sql`; upgraded environments retain historical entries alongside the baseline.
-
-### Seeding reference data
-
-`scripts/seed_data.py` provides targeted control over the baseline datasets when the full setup script is not required:
-
-```powershell
-python scripts/seed_data.py --currencies --units --dry-run
-python scripts/seed_data.py --currencies --units
-```
-
-The seeder upserts the canonical currency catalog (`USD`, `EUR`, `CLP`, `RMB`, `GBP`, `CAD`, `AUD`) using ASCII-safe symbols (`USD$`, `EUR`, etc.) and the measurement units referenced by the UI (`tonnes`, `kilograms`, `pounds`, `liters`, `cubic_meters`, `kilowatt_hours`). The setup script invokes the same seeder when `--seed-data` is provided and verifies the expected rows afterward, warning if any are missing or inactive.
-
-### Rollback guidance
-
-`scripts/setup_database.py` now tracks compensating actions when it creates the database or application role. If a later step fails, the script replays those rollback actions (dropping the newly created database or role and revoking grants) before exiting. Dry runs never register rollback steps and remain read-only.
-
-If the script reports that some rollback steps could not complete—for example because a connection cannot be established—rerun the script with `--dry-run` to confirm the desired end state and then apply the outstanding cleanup manually:
-
-```powershell
-python scripts/setup_database.py --ensure-database --ensure-role --dry-run -v
-
-# Manual cleanup examples when automation cannot connect
-psql -d postgres -c "DROP DATABASE IF EXISTS calminer"
-psql -d postgres -c "DROP ROLE IF EXISTS calminer"
-```
-
-After a failure and rollback, rerun the full setup once the environment issues are resolved.

-# Gitea Action Runner Setup
-
-This guide describes how to provision, configure, and maintain self-hosted runners for CalMiner's Gitea-based CI/CD pipelines.
-
-## 1. Purpose and Scope
-
-- Explain the role runners play in executing GitHub Actions–compatible workflows inside our private Gitea instance.
-- Define supported environments (Windows hosts running Docker for Linux containers today, Alpine or other Linux variants as future additions).
-- Provide repeatable steps so additional runners can be brought online quickly and consistently.
-
-## 2. Prerequisites
-
-- **Hardware**: Minimum 8 vCPU, 16 GB RAM, and 50 GB free disk. For Playwright-heavy suites, plan for ≥60 GB free to absorb browser caches.
-- **Operating system**: Current runner uses Windows 11 Pro (10.0.26100, 64-bit). Linux instructions mirror the same flow; see section 7 for Alpine specifics.
-- **Container engine**: Docker Desktop (Windows) or Docker Engine (Linux) with pull access to `docker.gitea.com/runner-images` and `postgres:16-alpine`.
-- **Dependencies**: `curl`, `tar`, PowerShell 7+ (Windows), or standard GNU utilities (Linux) to unpack releases.
-- **Gitea access**: Repository admin or site admin token with permission to register self-hosted runners (`Settings → Runners → New Runner`).
-
-### Current Runner Inventory (October 2025)
-
-- Hostname `DESKTOP-GLB3A15`; ASUS System Product Name chassis with AMD Ryzen 7 7700X (8C/16T) and ~63 GB usable RAM.
-- Windows 11 Pro 10.0.26100 (64-bit) hosting Docker containers for Ubuntu-based job images.
-- `act_runner` version `v0.2.13`; no `act_runner.yaml` present, so defaults apply (single concurrency, no custom labels beyond registration).
-- Registered against `http://192.168.88.30:3000` with labels:
-  - `ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest`
-  - `ubuntu-24.04:docker://docker.gitea.com/runner-images:ubuntu-24.04`
-  - `ubuntu-22.04:docker://docker.gitea.com/runner-images:ubuntu-22.04`
-- Runner metadata stored in `.runner`; removing this file forces re-registration and should only be done intentionally.
-
-## 3. Runner Installation
-
-### 3.1 Download and Extract
-
-```powershell
-$runnerVersion = "v0.2.13"
-$downloadUrl = "https://gitea.com/gitea/act_runner/releases/download/$runnerVersion/act_runner_${runnerVersion}_windows_amd64.zip"
-Invoke-WebRequest -Uri $downloadUrl -OutFile act_runner.zip
-Expand-Archive act_runner.zip -DestinationPath C:\Tools\act-runner -Force
-```
-
-For Linux, download the `linux_amd64.tar.gz` artifact and extract with `tar -xzf` into `/opt/act-runner`.
-
-### 3.2 Configure Working Directory
-
-```powershell
-Set-Location C:\Tools\act-runner
-New-Item -ItemType Directory -Path logs -Force | Out-Null
-```
-
-Ensure the directory is writable by the service account that will execute the runner.
-
-### 3.3 Register With Gitea
-
-1. In Gitea, navigate to the repository or organization **Settings → Runners → New Runner**.
-2. Copy the registration token and instance URL.
-3. Execute the registration wizard:
-
-```powershell
-.\act_runner.exe register --instance http://192.168.88.30:3000 --token <TOKEN> --labels "ubuntu-latest:docker://docker.gitea.com/runner-images:ubuntu-latest" "ubuntu-24.04:docker://docker.gitea.com/runner-images:ubuntu-24.04" "ubuntu-22.04:docker://docker.gitea.com/runner-images:ubuntu-22.04"
-```
-
-Linux syntax is identical using `./act_runner register`.
-
-This command populates `.runner` with the runner ID, UUID, and labels.
-
-## 4. Service Configuration
-
-### 4.1 Windows Service
-
-Act Runner provides a built-in service helper:
-
-```powershell
-.\act_runner.exe install
-.\act_runner.exe start
-```
-
-The service runs under `LocalSystem` by default. Use `.\act_runner.exe install --user <DOMAIN\User> --password <Secret>` if isolation is required.
-
-### 4.2 Linux systemd Unit
-
-Create `/etc/systemd/system/act-runner.service`:
-
-```ini
-[Unit]
-Description=Gitea Act Runner
-After=docker.service
-Requires=docker.service
-
-[Service]
-WorkingDirectory=/opt/act-runner
-ExecStart=/opt/act-runner/act_runner daemon
-Restart=always
-RestartSec=10
-Environment="HTTP_PROXY=http://apt-cacher:3142" "HTTPS_PROXY=http://apt-cacher:3142"
-
-[Install]
-WantedBy=multi-user.target
-```
-
-Enable and start:
-
-```bash
-sudo systemctl daemon-reload
-sudo systemctl enable --now act-runner.service
-```
-
-### 4.3 Environment Variables and Proxy Settings
-
-- Configure `HTTP_PROXY`, `HTTPS_PROXY`, and their lowercase variants to leverage the shared apt cache (`http://apt-cacher:3142`).
-- Persist Docker registry credentials (for `docker.gitea.com`) in the service user profile using `docker login`; workflows rely on cached authentication for builds.
-- To expose pip caching once infrastructure is available, set `PIP_INDEX_URL` and `PIP_EXTRA_INDEX_URL` at the service level.
-
-### 4.4 Logging
-
-- Windows services write to `%ProgramData%\act-runner\logs`. Redirect or forward to centralized logging if required.
-- Linux installations can leverage `journalctl -u act-runner` and logrotate rules for `/opt/act-runner/logs`.
-
-## 5. Network and Security
-
-- **Outbound**: Allow HTTPS traffic to the Gitea instance, Docker Hub, docker.gitea.com, npm (for Playwright), PyPI, and the apt cache proxy.
-- **Inbound**: No inbound ports are required; block unsolicited traffic on internet-facing hosts.
-- **Credentials**: Store deployment SSH keys and registry credentials in Gitea secrets, not on the runner host.
-- **Least privilege**: Run the service under a dedicated account with access only to Docker and required directories.
-
-## 6. Maintenance and Upgrades
-
-- **Version checks**: Monitor `https://gitea.com/gitea/act_runner/releases` and schedule upgrades quarterly or when security fixes drop.
-- **Upgrade procedure**: Stop the service, replace `act_runner` binary, restart. Re-registration is not required as long as `.runner` remains intact.
-- **Health checks**: Periodically validate connectivity with `act_runner exec --detect-event -W .gitea/workflows/test.yml` and inspect workflow durations to catch regressions.
-- **Cleanup**: Purge Docker images and volumes monthly (`docker system prune -af`) to reclaim disk space.
-- **Troubleshooting**: Use `act_runner diagnose` (if available in newer versions) or review logs for repeated failures; reset by stopping the service, deleting stale job containers (`docker ps -a`), and restarting.
-
-## 7. Alpine-based Runner Notes
-
-- Install baseline packages: `apk add docker bash curl coreutils nodejs npm python3 py3-pip libstdc++`.
-- Playwright requirements: add `apk add chromium nss freetype harfbuzz ca-certificates mesa-gl` or install Playwright browsers via `npx playwright install --with-deps` using the Alpine bundle.
-- Musl vs glibc: When workflows require glibc (e.g., certain Python wheels), include `apk add gcompat` or base images on `frolvlad/alpine-glibc`.
-- Systemd alternative: Use `rc-service` or `supervisord` to manage `act_runner daemon` on Alpine since systemd is absent.
-- Storage: Mount `/var/lib/docker` to persistent storage if running inside a VM, ensuring browser downloads and layer caches survive restarts.
-
-## 8. Appendix
-
-- **Troubleshooting checklist**:
-  - Verify Docker daemon is healthy (`docker info`).
-  - Confirm `.runner` file exists and lists expected labels.
-  - Re-run `act_runner register` if the runner no longer appears in Gitea.
-  - Check proxy endpoints are reachable before jobs start downloading dependencies.

-
-## Deployment Topology
-
-The CalMiner application is deployed using a multi-tier architecture consisting of the following layers:
-
-1. **Client Layer**: This layer consists of web browsers that interact with the application through a user interface rendered by Jinja2 templates and enhanced with JavaScript (Chart.js for dashboards).
-2. **Web Application Layer**: This layer hosts the FastAPI application, which handles API requests, business logic, and serves HTML templates. It communicates with the database layer for data persistence.
-3. **Database Layer**: This layer consists of a PostgreSQL database that stores all application data, including scenarios, parameters, costs, consumption, production outputs, equipment, maintenance logs, and simulation results.
-
-```mermaid
-graph TD

-    B --> C[Database Layer]
-```
-
-## Infrastructure Components
-
-The infrastructure components for the application include:
-
-- **Reverse Proxy (optional)**: An Nginx or Apache server can be used as a reverse proxy.
-- **Containerization**: Docker images are generated via the repository `Dockerfile`, using a multi-stage build to keep the final runtime minimal.
-- **CI/CD Pipeline**: Automated pipelines (Gitea Actions) run tests, build/push Docker images, and trigger deployments.
-  - **Gitea Actions Workflows**: Located under `.gitea/workflows/`, these workflows handle testing, building, pushing, and deploying the application.
-  - **Gitea Action Runners**: Self-hosted runners execute the CI/CD workflows.
-  - **Testing and Continuous Integration**: Automated tests ensure code quality before deployment, also documented in [Testing & CI](07_deployment/07_01_testing_ci.md.md).
-- **Docker Infrastructure**: Docker is used to containerize the application for consistent deployment across environments.
-- **Portainer**: Production deployment environment for managing Docker containers.
-  - **Web Server**: Hosts the FastAPI application and serves API endpoints.
-  - **Database Server**: PostgreSQL database for persisting application data.
-  - **Static File Server**: Serves static assets such as CSS, JavaScript, and image files.
-- **Cloud Infrastructure (optional)**: The application can be deployed on cloud platforms.

-## Environments
-
-The application can be deployed in multiple environments to support development, testing, and production.

-
-### Development Environment
-
-The development environment is set up for local development and testing. It includes:
-
-- Local PostgreSQL instance (docker compose recommended, script available at `docker-compose.postgres.yml`)
-- FastAPI server running in debug mode
-
-`docker-compose.dev.yml` encapsulates this topology:
-
-- `api` service mounts the repository for live reloads (`uvicorn --reload`) and depends on the database health check.
-- `db` service uses the Debian-based `postgres:16` image with UTF-8 locale configuration and persists data in `pg_data_dev`.
-- A shared `calminer_backend` bridge network keeps traffic contained; ports 8000/5432 are published for local tooling.
-
-See [docs/quickstart.md](../quickstart.md#compose-driven-development-stack) for command examples and volume maintenance tips.
-
-### Testing Environment
-
-The testing environment is set up for automated testing and quality assurance. It includes:
-
-- Staging PostgreSQL instance
-- FastAPI server running in testing mode
-- Automated test suite (e.g., pytest) for running unit and integration tests
-
-`docker-compose.test.yml` provisions an ephemeral CI-like stack:
-
-- `tests` service builds the application image, installs `requirements-test.txt`, runs the database setup script (dry-run + apply), then executes pytest.
-- `api` service is available on port 8001 for manual verification against the test database.
-- `postgres` service seeds a disposable Postgres 16 instance with health checks and named volumes (`pg_data_test`, `pip_cache_test`).
-
-Typical commands mirror the CI workflow (`docker compose -f docker-compose.test.yml run --rm tests`); the [quickstart](../quickstart.md#compose-driven-test-stack) lists variations and teardown steps.
-
-### Production Environment
-
-The production environment is set up for serving live traffic and includes:
-
-- Production PostgreSQL instance
-- FastAPI server running in production mode
-- Load balancer (Traefik) for distributing incoming requests
-- Monitoring and logging tools for tracking application performance
-
-#### Production docker compose topology
-
-- `docker-compose.prod.yml` defines the runtime topology for operator-managed deployments.
-- `api` service runs the FastAPI image with resource limits (`API_LIMIT_CPUS`, `API_LIMIT_MEMORY`) and a `/health` probe consumed by Traefik and the Compose health check.
-- `traefik` service (enabled via the `reverse-proxy` profile) terminates TLS using the ACME resolver configured by `TRAEFIK_ACME_EMAIL` and routes `CALMINER_DOMAIN` traffic to the API.
-- `postgres` service (enabled via the `local-db` profile) exists for edge deployments without managed PostgreSQL and persists data in the `pg_data_prod` volume while mounting `./backups` for operator snapshots.
-- All services join the configurable `CALMINER_NETWORK` (defaults to `calminer_backend`) to keep traffic isolated from host networks.
-
-Deployment workflow:
-
-1. Copy `config/setup_production.env.example` to `config/setup_production.env` and populate domain, registry image tag, database credentials, and resource budgets.
-2. Launch the stack with `docker compose --env-file config/setup_production.env -f docker-compose.prod.yml --profile reverse-proxy up -d` (append `--profile local-db` when hosting Postgres locally).
-3. Run database migrations and seeding using `docker compose --env-file config/setup_production.env -f docker-compose.prod.yml run --rm api python scripts/setup_database.py --run-migrations --seed-data`.
-4. Monitor container health via `docker compose -f docker-compose.prod.yml ps` or Traefik dashboards; the API health endpoint returns `{ "status": "ok" }` when ready.
-5. Shut down with `docker compose -f docker-compose.prod.yml down` (volumes persist unless `-v` is supplied).
-
-## Containerized Deployment Flow
-
-The Docker-based deployment path aligns with the solution strategy documented in [Solution Strategy](04_solution_strategy.md) and the CI practices captured in [Testing & CI](07_deployment/07_01_testing_ci.md.md).
-
-### Image Build
-
-- The multi-stage `Dockerfile` installs dependencies in a builder layer (including system compilers and Python packages) and copies only the required runtime artifacts to the final image.
-- Build arguments are minimal; database configuration is supplied at runtime via granular variables (`DATABASE_DRIVER`, `DATABASE_HOST`, `DATABASE_PORT`, `DATABASE_USER`, `DATABASE_PASSWORD`, `DATABASE_NAME`, optional `DATABASE_SCHEMA`). Secrets and configuration should be passed via environment variables or an orchestrator.
-- The resulting image exposes port `8000` and starts `uvicorn main:app` (see main [README.md](../../README.md)).
-
-### Runtime Environment
-
-- For single-node deployments, run the container alongside PostgreSQL/Redis using Docker Compose or an equivalent orchestrator.
-- A reverse proxy (Traefik) terminates TLS and forwards traffic to the container on port `8000`.
-- Migrations must be applied prior to rolling out a new image; automation can hook into the deploy step to run `scripts/run_migrations.py`.
-
-### CI/CD Integration
-
-- Gitea Actions workflows reside under `.gitea/workflows/`.
-- `test.yml` executes the pytest suite using cached pip dependencies.
-- `build-and-push.yml` logs into the container registry, rebuilds the Docker image using GitHub Actions cache-backed layers, and pushes `latest` (and additional tags as required).
-- `deploy.yml` connects to the target host via SSH, pulls the pushed tag, stops any existing container, and launches the new version.
-- Required secrets: `REGISTRY_URL`, `REGISTRY_USERNAME`, `REGISTRY_PASSWORD`, `SSH_HOST`, `SSH_USERNAME`, `SSH_PRIVATE_KEY`.
-- Extend these workflows when introducing staging/blue-green deployments; keep cross-links with [Testing & CI](07_deployment/07_01_testing_ci.md.md) up to date.
-
-## Integrations and Future Work (deployment-related)
-
-- **Persistence of results**: `/api/simulations/run` currently returns in-memory results; next iteration should persist to `simulation_result` and reference scenarios.
-- **Deployment**: implement infrastructure-as-code (e.g., Terraform/Ansible) to provision the hosting environment and maintain parity across dev/stage/prod.

-# 08 — Concepts
-
-## Key Concepts
-
-### Scenario
-
-A `scenario` represents a distinct mining project configuration, encapsulating all relevant parameters, costs, consumption, production outputs, equipment, maintenance logs, and simulation results. Each scenario is independent, allowing users to model and analyze different mining strategies.
-
-### Parameterization
-
-Parameters are defined for each scenario to capture inputs such as resource consumption rates, production targets, cost factors, and equipment specifications. Parameters can have fixed values or be linked to probability distributions for stochastic simulations.
-
-### Monte Carlo Simulation
-
-The Monte Carlo simulation engine allows users to perform risk analysis by running multiple iterations of a scenario with varying input parameters based on defined probability distributions. This helps in understanding the range of possible outcomes and their associated probabilities.
-
-## Domain Model
-
-The domain model consists of the following key entities:
-
-- `Scenario`: Represents a mining project configuration.
-- `Parameter`: Input values for scenarios, which can be fixed or probabilistic.
-- `Cost`: Tracks capital and operational expenditures.
-- `Consumption`: Records resource usage.
-- `ProductionOutput`: Captures production metrics.
-- `Equipment`: Represents mining equipment associated with a scenario.
-- `Maintenance`: Logs maintenance events for equipment.
-- `SimulationResult`: Stores results from Monte Carlo simulations.
-- `Distribution`: Defines probability distributions for stochastic parameters.
-- `User`: Represents application users and their roles.
-- `Report`: Generated reports summarizing scenario analyses.
-- `Dashboard`: Visual representation of key performance indicators and metrics.
-- `AuditLog`: Tracks changes and actions performed within the application.
-- `Notification`: Alerts and messages related to scenario events and updates.
-- `Tag`: Labels for categorizing scenarios and other entities.
-- `Attachment`: Files associated with scenarios, such as documents or images.
-- `Version`: Tracks different versions of scenarios and their configurations.
-
-### Detailed Domain Models
-
-See [Domain Models](08_concepts/08_01_domain_models.md) document for detailed class diagrams and entity relationships.
-
-## Data Model Highlights
-
-- `scenario`: central entity describing a mining scenario; owns relationships to cost, consumption, production, equipment, and maintenance tables.
-- `capex`, `opex`: monetary tracking linked to scenarios.
-- `consumption`: resource usage entries parameterized by scenario and description.
-- `parameter`: scenario inputs with base `value` and optional distribution linkage via `distribution_id`, `distribution_type`, and JSON `distribution_parameters` to support simulation sampling.
-- `production_output`: production metrics per scenario.
-- `equipment` and `maintenance`: equipment inventory and maintenance events with dates/costs.
-- `simulation_result`: staging table for future Monte Carlo outputs (not yet populated by `run_simulation`).
-- `application_setting`: centralized key/value store for UI and system configuration, supporting typed values, categories, and editability flags so administrators can manage theme variables and future global options without code changes.

-# User Roles and Permissions Model
-
-This document outlines the proposed user roles and permissions model for the CalMiner application.
-
-## User Roles
-
-- **Admin:** Full access to all features, including user management, application settings, and all data.
-- **Analyst:** Can create, view, edit, and delete scenarios, run simulations, and view reports. Cannot modify application settings or manage users.
-- **Viewer:** Can view scenarios, simulations, and reports. Cannot create, edit, or delete anything.
-
-## Permissions (examples)
-
-- `users:manage`: Admin only.
-- `settings:manage`: Admin only.
-- `scenarios:create`: Admin, Analyst.
-- `scenarios:view`: Admin, Analyst, Viewer.
-- `scenarios:edit`: Admin, Analyst.
-- `scenarios:delete`: Admin, Analyst.
-- `simulations:run`: Admin, Analyst.
-- `simulations:view`: Admin, Analyst, Viewer.
-- `reports:view`: Admin, Analyst, Viewer.
-
-## Authentication System
-
-The authentication system uses JWT (JSON Web Tokens) for securing API endpoints. Users can register with a username, email, and password. Passwords are hashed using a `passlib` CryptContext for secure, configurable hashing. Upon successful login, an access token is issued, which must be included in subsequent requests for protected resources.
-
-## Key Components
-
-- **Password Hashing:** `passlib.context.CryptContext` with `bcrypt` scheme.
-- **Token Creation & Verification:** `jose.jwt` for encoding and decoding JWTs.
-- **Authentication Flow:**
-  1. User registers via `/users/register`.
-  2. User logs in via `/users/login` to obtain an access token.
-  3. The access token is sent in the `Authorization` header (Bearer token) for protected routes.
-  4. The `get_current_user` dependency verifies the token and retrieves the authenticated user.
-- **Password Reset:** A placeholder `forgot_password` endpoint is available, and a `reset_password` endpoint allows users to set a new password with a valid token (token generation and email sending are not yet implemented).

-# CI Cache Troubleshooting
-
-## Background
-
-The test workflow (`.gitea/workflows/test.yml`) uses the `actions/cache` action to reuse the pip download cache located at `~/.cache/pip`. The cache key now hashes both `requirements.txt` and `requirements-test.txt` so the cache stays aligned with dependency changes.
-
-## Current Observation
-
-Recent CI runs report the following warning when the cache step executes:
-
-```text
-::warning::Failed to restore: getCacheEntry failed: connect ETIMEDOUT 172.17.0.5:40181
-Cache not found for input keys: Linux-pip-<hash>, Linux-pip-
-```
-
-The timeout indicates the runner cannot reach the cache backend rather than a normal cache miss.
-
-## Recommended Follow-Up
-
-- Confirm that the Actions cache service is enabled for the CI environment (Gitea runners require the cache server URL to be provided via `ACTIONS_CACHE_URL` and `ACTIONS_RUNTIME_URL`).
-- Verify network connectivity from the runner to the cache service endpoint and ensure required ports are open.
-- After connectivity is restored, rerun the workflow to allow the cache to be populated and confirm subsequent runs restore the cache without warnings.
-
-## Interim Guidance
-
-- The workflow will proceed without cached dependencies, but package installs may take longer.
-- Keep the cache step in place so it begins working automatically once the infrastructure is configured.

-CREATE USER calminer_user WITH PASSWORD 'your_password';
-```
-
-1. Create database:
-
-```sql
-CREATE DATABASE calminer;
-```
-
-### Environment Variables
-
-1. Copy `.env.example` to `.env` at project root.
-1. Edit `.env` to set database connection details:
-
-```dotenv
-DATABASE_DRIVER=postgresql
-DATABASE_HOST=localhost
-DATABASE_PORT=5432
-DATABASE_USER=calminer_user
-DATABASE_PASSWORD=your_password
-DATABASE_NAME=calminer
-DATABASE_SCHEMA=public
-```
-
-1. The application uses `python-dotenv` to load these variables. A legacy `DATABASE_URL` value is still accepted if the granular keys are omitted.
-
-### Running the Application
-
-```powershell
-# Start the FastAPI server
-uvicorn main:app --reload
-```
-
-## Testing
-
-```powershell
-pytest
-```
-
-E2E tests use Playwright and a session-scoped `live_server` fixture that starts the app at `http://localhost:8001` for browser-driven tests.

-# Staging Environment Setup
-
-This guide outlines how to provision and validate the CalMiner staging database using `scripts/setup_database.py`. It complements the local and CI-focused instructions in `docs/quickstart.md`.
-
-## Prerequisites
-
-- Network access to the staging infrastructure (VPN or bastion, as required by ops).
-- Provisioned PostgreSQL instance with superuser or delegated admin credentials for maintenance.
-- Application credentials (role + password) dedicated to CalMiner staging.
-- The application repository checked out with Python dependencies installed (`pip install -r requirements.txt`).
-- Optional but recommended: a writable directory (for example `reports/`) to capture setup logs.
-
-> Replace the placeholder values in the examples below with the actual host, port, and credential details supplied by ops.
-
-## Environment Configuration
-
-Populate the following environment variables before invoking the setup script. Store them in a secure location such as `config/setup_staging.env` (excluded from source control) and load them with `dotenv` or your shell profile.
-
-| Variable                      | Description                                                                               |
-| ----------------------------- | ----------------------------------------------------------------------------------------- |
-| `DATABASE_HOST`               | Staging PostgreSQL hostname or IP (for example `staging-db.internal`).                    |
-| `DATABASE_PORT`               | Port exposed by the staging PostgreSQL service (default `5432`).                          |
-| `DATABASE_NAME`               | CalMiner staging database name (for example `calminer_staging`).                          |
-| `DATABASE_USER`               | Application role used by the FastAPI app (for example `calminer_app`).                    |
-| `DATABASE_PASSWORD`           | Password for the application role.                                                        |
-| `DATABASE_SCHEMA`             | Optional non-public schema; omit or set to `public` otherwise.                            |
-| `DATABASE_SUPERUSER`          | Administrative role with rights to create roles/databases (for example `calminer_admin`). |
-| `DATABASE_SUPERUSER_PASSWORD` | Password for the administrative role.                                                     |
-| `DATABASE_SUPERUSER_DB`       | Database to connect to for admin tasks (default `postgres`).                              |
-| `DATABASE_ADMIN_URL`          | Optional DSN that overrides the granular admin settings above.                            |
-
-You may also set `DATABASE_URL` for application runtime convenience, but the setup script only requires the values listed in the table.
-
-### Loading Variables (PowerShell example)
-
-```powershell
-$env:DATABASE_HOST = "staging-db.internal"
-$env:DATABASE_PORT = "5432"
-$env:DATABASE_NAME = "calminer_staging"
-$env:DATABASE_USER = "calminer_app"
-$env:DATABASE_PASSWORD = "<app-password>"
-$env:DATABASE_SUPERUSER = "calminer_admin"
-$env:DATABASE_SUPERUSER_PASSWORD = "<admin-password>"
-$env:DATABASE_SUPERUSER_DB = "postgres"
-```
-
-For bash shells, export the same variables using `export VARIABLE=value` or load them through `dotenv`.
-
-## Setup Workflow
-
-Run the setup script in three phases to validate idempotency and capture diagnostics:
-
-1. **Dry run (diagnostic):**
-
-   ```powershell
-   python scripts/setup_database.py --ensure-database --ensure-role --ensure-schema --initialize-schema --run-migrations --seed-data --dry-run -v `
-     2>&1 | Tee-Object -FilePath reports/setup_staging_dry_run.log
-   ```
-
-   Confirm that the script reports planned actions without failures. If the application role is missing, a dry run will log skip messages until a live run creates the role.
-
-2. **Apply changes:**
-
-   ```powershell
-   python scripts/setup_database.py --ensure-database --ensure-role --ensure-schema --initialize-schema --run-migrations --seed-data -v `
-     2>&1 | Tee-Object -FilePath reports/setup_staging_apply.log
-   ```
-
-   Verify the log for successful database creation, role grants, migration execution, and seed verification.
-
-3. **Post-apply dry run:**
-
-   ```powershell
-   python scripts/setup_database.py --ensure-database --ensure-role --ensure-schema --initialize-schema --run-migrations --seed-data --dry-run -v `
-     2>&1 | Tee-Object -FilePath reports/setup_staging_post_apply.log
-   ```
-
-   This run should confirm that all schema objects, migrations, and seed data are already in place.
-
-## Validation Checklist
-
-- [ ] Confirm the staging application can connect using the application DSN (for example, run `pytest tests/e2e/test_smoke.py` against staging or trigger a smoke test workflow).
-- [ ] Inspect `schema_migrations` to ensure the baseline migration (`000_base.sql`) is recorded.
-- [ ] Spot-check seeded reference data (`currency`, `measurement_unit`) for correctness.
-- [ ] Capture and archive the three setup logs in a shared location for audit purposes.
-
-## Troubleshooting
-
-- If the dry run reports skipped actions because the application role does not exist, proceed with the live run; subsequent dry runs will validate as expected.
-- Connection errors usually stem from network restrictions or incorrect credentials. Validate reachability with `psql` or `pg_isready` using the same host/port and credentials.
-- For permission issues during migrations or seeding, confirm the admin role has rights on the target database and that the application role inherits the expected privileges.
-
-## Rollback Guidance
-
-- Database creation and role grants register rollback actions when not running in dry-run mode. If a later step fails, rerun the script without `--dry-run`; it will automatically revoke grants or drop newly created resources as part of the rollback routine.
-- For staged environments where manual intervention is required, coordinate with ops before dropping databases or roles.
-
-## Next Steps
-
-- Keep this document updated as staging infrastructure evolves (for example, when migrating to managed services or rotating credentials).

-# UI, templates and styling
-
-This document outlines the UI structure, template components, CSS variable conventions, and per-page data/actions for the CalMiner application.
-
-## Reusable Template Components
-
-To reduce duplication across form-centric pages, shared Jinja macros live in `templates/partials/components.html`.
-
-- `select_field(...)`: renders labeled `<select>` controls with consistent placeholder handling and optional preselection. Existing JavaScript modules continue to target the generated IDs, so template calls must pass the same identifiers (`consumption-form-scenario`, etc.).
-- `feedback(...)` and `empty_state(...)`: wrap status messages in standard classes (`feedback`, `empty-state`) with optional `hidden` toggles so scripts can control visibility without reimplementing markup.
-- `table_container(...)`: provides a semantic wrapper and optional heading around tabular content; the `{% call %}` body supplies the `<thead>`, `<tbody>`, and `<tfoot>` elements while the macro applies the `table-container` class and manages hidden state.
-
-Pages like `templates/consumption.html` and `templates/costs.html` already consume these helpers to keep markup aligned while preserving existing JavaScript selectors.
-
-Import macros via:
-
-```jinja
-{% from "partials/components.html" import select_field, feedback, table_container with context %}
-```
-
-## Styling Audit Notes (2025-10-21)
-
-- **Spacing**: Panels (`section.panel`) sometimes lack consistent vertical rhythm between headings, form grids, and tables. Extra top/bottom margin utilities would help align content.
-- **Typography**: Headings rely on browser defaults; font-size scale is uneven between `<h2>` and `<h3>`. Define explicit scale tokens (e.g., `--font-size-lg`) for predictable sizing.
-- **Forms**: `.form-grid` uses fixed column gaps that collapse on small screens; introduce responsive grid rules to stack gracefully below ~768px.
-- **Tables**: `.table-container` wrappers need overflow handling for narrow viewports; consider `overflow-x: auto` with padding adjustments.
-- **Feedback/Empty states**: Messages use default font weight and spacing; a utility class for margin/padding would ensure consistent separation from forms or tables.
-
-## CSS Variable Naming Conventions
-
-The project adheres to a clear and descriptive naming convention for CSS variables, primarily defined in `static/css/main.css`.
-
-## Naming Structure
-
-Variables are prefixed based on their category:
-
-- `--color-`: For all color-related variables (e.g., `--color-primary`, `--color-background`, `--color-text-primary`).
-- `--space-`: For spacing and layout-related variables (e.g., `--space-sm`, `--space-md`, `--space-lg`).
-- `--font-size-`: For font size variables (e.g., `--font-size-base`, `--font-size-lg`).
-- Other specific prefixes for components or properties (e.g., `--panel-radius`, `--table-radius`).
-
-## Descriptive Names
-
-Color names are chosen to be semantically meaningful rather than literal color values, allowing for easier theme changes. For example:
-
-- `--color-primary`: Represents the main brand color.
-- `--color-accent`: Represents an accent color used for highlights.
-- `--color-text-primary`: The main text color.
-- `--color-text-muted`: A lighter text color for less emphasis.
-- `--color-surface`: The background color for UI elements like cards or panels.
-- `--color-background`: The overall page background color.
-
-This approach ensures that the CSS variables are intuitive, maintainable, and easily adaptable for future theme customizations.
-
-## Per-page data & actions
-
-Short reference of per-page APIs and primary actions used by templates and scripts.
-
-- Scenarios (`templates/ScenarioForm.html`):
-
-  - Data: `GET /api/scenarios/`
-  - Actions: `POST /api/scenarios/`
-
-- Parameters (`templates/ParameterInput.html`):
-
-  - Data: `GET /api/scenarios/`, `GET /api/parameters/`
-  - Actions: `POST /api/parameters/`
-
-- Costs (`templates/costs.html`):
-
-  - Data: `GET /api/costs/capex`, `GET /api/costs/opex`
-  - Actions: `POST /api/costs/capex`, `POST /api/costs/opex`
-
-- Consumption (`templates/consumption.html`):
-
-  - Data: `GET /api/consumption/`
-  - Actions: `POST /api/consumption/`
-
-- Production (`templates/production.html`):
-
-  - Data: `GET /api/production/`
-  - Actions: `POST /api/production/`
-
-- Equipment (`templates/equipment.html`):
-
-  - Data: `GET /api/equipment/`
-  - Actions: `POST /api/equipment/`
-
-- Maintenance (`templates/maintenance.html`):
-
-  - Data: `GET /api/maintenance/` (pagination support)
-  - Actions: `POST /api/maintenance/`, `PUT /api/maintenance/{id}`, `DELETE /api/maintenance/{id}`
-
-- Simulations (`templates/simulations.html`):
-
-  - Data: `GET /api/scenarios/`, `GET /api/parameters/`
-  - Actions: `POST /api/simulations/run`
-
-- Reporting (`templates/reporting.html` and `templates/Dashboard.html`):
-  - Data: `POST /api/reporting/summary` (accepts arrays of `{ "result": float }` objects)
-  - Actions: Trigger summary refreshes and export/download actions.
-
-## Navigation Structure
-
-The application uses a sidebar navigation menu organized into the following top-level categories:
-
-- **Dashboard**: Main overview page.
-- **Overview**: Sub-menu for core scenario inputs.
-  - Parameters: Process parameters configuration.
-  - Costs: Capital and operating costs.
-  - Consumption: Resource consumption tracking.
-  - Production: Production output settings.
-  - Equipment: Equipment inventory (with Maintenance sub-item).
-- **Simulations**: Monte Carlo simulation runs.
-- **Analytics**: Reporting and analytics.
-- **Settings**: Administrative settings (with Themes and Currency Management sub-items).
-
-## UI Template Audit (2025-10-20)
-
-- Existing HTML templates: `ScenarioForm.html`, `ParameterInput.html`, and `Dashboard.html` (reporting summary view).
-- Coverage gaps remain for costs, consumption, production, equipment, maintenance, and simulation workflows—no dedicated templates yet.
-- Shared layout primitives (navigation/header/footer) are absent; current pages duplicate boilerplate markup.
-- Dashboard currently covers reporting metrics but should be wired to a central `/` route once the shared layout lands.
-- Next steps: introduce a `base.html`, refactor existing templates to extend it, and scaffold placeholder pages for the remaining features.

-# Consolidated Migration Baseline Plan
-
-This note outlines the content and structure of the planned baseline migration (`scripts/migrations/000_base.sql`). The objective is to capture the currently required schema changes in a single idempotent script so that fresh environments only need to apply one SQL file before proceeding with incremental migrations.
-
-## Guiding Principles
-
-1. **Idempotent DDL**: Every `CREATE` or `ALTER` statement must tolerate repeated execution. Use `IF NOT EXISTS` guards or existence checks (`information_schema`) where necessary.
-2. **Order of Operations**: Create reference tables first, then update dependent tables, finally enforce foreign keys and constraints.
-3. **Data Safety**: Default data seeded by migrations should be minimal and in ASCII-only form to avoid encoding issues in various shells and CI logs.
-4. **Compatibility**: The baseline must reflect the schema shape expected by the current SQLAlchemy models, API routes, and seeding scripts.
-
-## Schema Elements to Include
-
-### 1. `currency` Table
-
-- Columns: `id SERIAL PRIMARY KEY`, `code VARCHAR(3) UNIQUE NOT NULL`, `name VARCHAR(128) NOT NULL`, `symbol VARCHAR(8)`, `is_active BOOLEAN NOT NULL DEFAULT TRUE`.
-- Index: implicit via unique constraint on `code`.
-- Seed rows matching `scripts.seed_data.CURRENCY_SEEDS` (ASCII-only symbols such as `USD$`, `CAD$`).
-- Upsert logic using `ON CONFLICT (code) DO UPDATE` to keep names/symbols in sync when rerun.
-
-### 2. Currency Integration for CAPEX/OPEX
-
-- Add `currency_id INTEGER` columns with `IF NOT EXISTS` guards.
-- Populate `currency_id` from legacy `currency_code` if the column exists.
-- Default null `currency_id` values to the USD row, then `ALTER` to `SET NOT NULL`.
-- Create `fk_capex_currency` and `fk_opex_currency` constraints with `ON DELETE RESTRICT` semantics.
-- Drop legacy `currency_code` column if it exists (safe because new column holds data).
-
-### 3. Measurement Metadata on Consumption/Production
-
-- Ensure `consumption` and `production_output` tables have `unit_name VARCHAR(64)` and `unit_symbol VARCHAR(16)` columns with `IF NOT EXISTS` guards.
-
-### 4. `measurement_unit` Reference Table
-
-- Columns: `id SERIAL PRIMARY KEY`, `code VARCHAR(64) UNIQUE NOT NULL`, `name VARCHAR(128) NOT NULL`, `symbol VARCHAR(16)`, `unit_type VARCHAR(32) NOT NULL`, `is_active BOOLEAN NOT NULL DEFAULT TRUE`, `created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()`, `updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()`.
-- Assume a simple trigger to maintain `updated_at` is deferred: automate via application layer later; for now, omit trigger.
-- Seed rows matching `MEASUREMENT_UNIT_SEEDS` (ASCII names/symbols). Use `ON CONFLICT (code) DO UPDATE` to keep descriptive fields aligned.
-
-### 5. Transaction Handling
-
-- Wrap the main operations in a single `BEGIN; ... COMMIT;` block.
-- Use subtransactions (`DO $$ ... $$;`) only where conditional logic is required (e.g., checking column existence before backfill).
-
-## Migration Tracking Alignment
-
-- Baseline file will be named `000_base.sql`. After execution, insert a row into `schema_migrations` with filename `000_base.sql` to keep the tracking table aligned.
-- Existing migrations (`20251021_add_currency_and_unit_fields.sql`, `20251022_create_currency_table_and_fks.sql`) remain for historical reference but will no longer be applied to new environments once the baseline is present.
-
-## Next Steps
-
-1. Draft `000_base.sql` reflecting the steps above.
-2. Update `run_migrations` to recognise the baseline file and mark older migrations as applied when the baseline exists.
-3. Provide documentation in `docs/quickstart.md` explaining how to reset an environment using the baseline plus seeds.

-# Roadmap
-
-## Overview
-
-## Scenario Enhancements
-
-For each scenario, the goal is to evaluate financial viability, operational efficiency, and risk factors associated with the mining project. This data is used to perform calculations, generate reports, and visualize results through charts and dashboards, enabling users to make informed decisions based on comprehensive analysis.
-
-### Scenario & Data Management
-
-Scenarios are the core organizational unit within CalMiner, allowing users to create, manage, and analyze different mining project configurations. Each scenario encapsulates a unique set of parameters and data inputs that define the mining operation being modeled.
-
-#### Scenario Creation
-
-Users can create new scenarios by providing a unique name and description. The system will generate a new scenario with default parameters, which can be customized later.
-
-#### Scenario Management
-
-Users can manage existing scenarios by modifying their parameters, adding new data inputs, or deleting them as needed.
-
-#### Data Inputs
-
-Users can define and manage various data inputs for each scenario, including:
-
-- **Geological Data**: Input data related to the geological characteristics of the mining site.
-- **Operational Parameters**: Define parameters such as mining methods, equipment specifications, and workforce details.
-- **Financial Data**: Input cost structures, revenue models, and financial assumptions.
-- **Environmental Data**: Include data related to environmental impact, regulations, and sustainability practices.
-- **Technical Data**: Specify technical parameters such as ore grades, recovery rates, and processing methods.
-- **Social Data**: Incorporate social impact assessments, community engagement plans, and stakeholder analysis.
-- **Regulatory Data**: Include data related to legal and regulatory requirements, permits, and compliance measures.
-- **Market Data**: Input market conditions, commodity prices, and economic indicators that may affect the mining operation.
-- **Risk Data**: Define risk factors, probabilities, and mitigation strategies for the mining project.
-- **Logistical Data**: Include data related to transportation, supply chain management, and infrastructure requirements.
-- **Maintenance Data**: Input maintenance schedules, costs, and equipment reliability metrics.
-- **Human Resources Data**: Define workforce requirements, training programs, and labor costs.
-- **Health and Safety Data**: Include data related to workplace safety protocols, incident rates, and health programs.
