# Changelog

All notable changes to Seismo Fleet Manager will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.2.1] - 2025-12-03

### Added
- `/settings` roster manager page with CSV export/import, live stats, and danger-zone reset controls.
- `/api/settings` router that exposes `export-csv`, `stats`, `roster-units`, `import-csv-replace`, and the clear-* endpoints backing the UI.
- Dedicated HTMX partials/tabs for deployed, benched, retired, and ignored units plus new ignored-table UI to unignore or delete entries.

### Changed
- Roster and unit detail templates now display device-type specific metadata (calibration windows, modem pairings, IP/phone fields) alongside inline actions.
- Base navigation highlights the new settings workflow and routes retired/ignored buckets through dedicated endpoints + partials.

### Fixed
- Snapshot summary counts only consider deployed units, preventing dashboard alerts from including benched hardware.
- Snapshot payloads now include address/coordinate metadata so map widgets and CSV exports stay accurate.

## [0.2.0] - 2025-12-03

### Added
- Device-type aware roster schema (seismographs vs modems) with new metadata columns plus `backend/migrate_add_device_types.py` for upgrading existing SQLite files.
- `create_test_db.py` helper that generates a ready-to-use demo database with sample seismographs, modems, and emitter rows.
- Ignore list persistence/API so noisy legacy emitters can be quarantined via `/api/roster/ignore` and surfaced in the UI.
- Roster page enhancements: Add Unit modal, CSV import modal, and HTMX-powered table fed by `/partials/roster-table`.
- Unit detail view rewritten to fetch data via API, expose deployment status, and allow edits to all metadata.

### Changed
- Snapshot service now merges roster + emitter data into active/benched/retired/unknown buckets and includes device-specific metadata in each record.
- Roster edit endpoints parse date fields, manage modem/seismograph specific attributes, and guarantee records exist when toggling deployed/retired states.
- Dashboard partial endpoints are grouped under `/dashboard/*` so HTMX tabs stay in sync with the consolidated snapshot payload.

### Fixed
- Toggling deployed/retired flags no longer fails when a unit does not exist because the router now auto-creates placeholder roster rows.
- CSV import applies address/coordinate updates instead of silently dropping unknown columns.

## [0.1.1] - 2025-12-02

### Added
- **Roster Editing API**: Full CRUD operations for roster management
  - `POST /api/roster/add` - Add new units to roster
  - `POST /api/roster/set-deployed/{unit_id}` - Toggle deployment status
  - `POST /api/roster/set-retired/{unit_id}` - Toggle retired status
  - `POST /api/roster/set-note/{unit_id}` - Update unit notes
- **CSV Import**: Bulk roster import functionality
  - `POST /api/roster/import-csv` - Import units from CSV file
  - Support for all roster fields: unit_id, unit_type, deployed, retired, note, project_id, location
  - Optional update_existing parameter to control duplicate handling
  - Detailed import summary with added/updated/skipped/error counts
- **Enhanced Database Models**:
  - Added `project_id` field to RosterUnit model
  - Added `location` field to RosterUnit model
  - Added `last_updated` timestamp tracking
- **Dashboard Enhancements**:
  - Separate views for Active, Benched, and Retired units
  - New endpoints: `/dashboard/active` and `/dashboard/benched`

### Fixed
- Database session management bug in `emit_status_snapshot()`
  - Added `get_db_session()` helper function for direct session access
  - Implemented proper session cleanup with try/finally blocks
- Database schema synchronization issues
  - Database now properly recreates when model changes are detected

### Changed
- Updated RosterUnit model to include additional metadata fields
- Improved error handling in CSV import with row-level error reporting
- Enhanced snapshot service to properly manage database connections

### Technical Details
- All roster editing endpoints use Form data for better HTML form compatibility
- CSV import uses multipart/form-data for file uploads
- Boolean fields in CSV accept: 'true', '1', 'yes' (case-insensitive)
- Database sessions now properly closed to prevent connection leaks
