feat: Refactor project creation and management to support modular project types

- Updated project creation modal to allow selection of optional modules (Sound and Vibration Monitoring).
- Modified project dashboard and header to display active modules and provide options to add/remove them.
- Enhanced project detail view to dynamically adjust UI based on enabled modules.
- Implemented a new migration script to create a `project_modules` table and seed it based on existing project types.
- Adjusted form submissions to handle module selections and ensure proper API interactions for module management.

 # Changelog
 
-All notable changes to Seismo Fleet Manager will be documented in this file.
+All notable changes to Terra-View 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).
 
+## [0.9.3] - 2026-03-28
+
+### Added
+- **Monitoring Session Detail Page**: New dedicated page for each session showing session info, data files (with View/Report/Download actions), an editable session panel, and report actions.
+- **Session Calendar with Gantt Bars**: Monthly calendar view below the session list, showing each session as a Gantt-style bar. The dim bar represents the full device on/off window; the bright bar highlights the effective recording window. Bars extend edge-to-edge across day cells for sessions spanning midnight.
+- **Configurable Period Windows**: Sessions now store `period_start_hour` and `period_end_hour` to define the exact hours that count toward reports, replacing hardcoded day/night defaults. The session edit panel shows a "Required Recording Window" section with a live preview (e.g. "7:00 AM → 7:00 PM") and a Defaults button that auto-fills based on period type.
+- **Report Date Field**: Sessions can now store an explicit `report_date` to override the automatic target-date heuristic — useful when a device ran across multiple days but only one specific day's data is needed for the report.
+- **Effective Window on Session Info**: Session detail and session cards now show an "Effective" row displaying the computed recording window dates and times in local time.
+- **Vibration Project Redesign**: Vibration project detail page is stripped back to project details and monitoring locations only. Each location supports assigning a seismograph and optional modem. Sound-specific tabs (Schedules, Sessions, Data Files, Assigned Units) are hidden for vibration projects.
+- **Modem Assignment on Locations**: Vibration monitoring locations now support an optional paired modem alongside the seismograph. The swap endpoint handles both assignments atomically, updating bidirectional pairing fields on both units.
+- **Available Modems Endpoint**: New `GET /api/projects/{project_id}/available-modems` endpoint returning all deployed, non-retired modems for use in assignment dropdowns.
+
+### Fixed
+- **Active Assignment Checks**: Unified all `UnitAssignment` "active" checks from `status == "active"` to `assigned_until IS NULL` throughout `project_locations.py` and `projects.py` for consistency with the canonical active definition.
+
+### Changed
+- **Sound-Only Endpoint Guards**: FTP browser, RND viewer, Excel report generation, combined report wizard, and data upload endpoints now return HTTP 400 if called on a non-sound-monitoring project.
+
+### Migration Notes
+Run on each database before deploying:
+```bash
+docker compose exec terra-view python3 backend/migrate_add_session_period_hours.py
+docker compose exec terra-view python3 backend/migrate_add_session_report_date.py
+```
+
+---
+
+## [0.9.2] - 2026-03-27
+
+### Added
+- **Deployment Records**: Seismographs now track a full deployment history (location, project, dates). Each deployment is logged on the unit detail page with start/end dates, and the fleet calendar service uses this history for availability calculations.
+- **Allocated Unit Status**: New `allocated` status for units reserved for an upcoming job but not yet deployed. Allocated units appear in the dashboard summary, roster filters, and devices table with visual indicators.
+- **Project Allocation**: Units can be linked to a project via `allocated_to_project_id`. Allocation is shown on the unit detail page and in a new quick-info modal accessible from the fleet calendar and roster.
+- **Quick-Info Unit Modal**: Click any unit in the fleet calendar or roster to open a modal showing cal status, project allocation, upcoming jobs, and deployment state — without leaving the page.
+- **Cal Date in Planner**: When a unit is selected for a monitoring location slot in the Job Planner, its calibration expiry date is now shown inline so you can spot near-expiry units before committing.
+- **Inline Seismograph Editing**: Unit rows in the seismograph dashboard now support inline editing of cal date, notes, and deployment status without navigating to the full detail page.
+
+### Migration Notes
+Run on each database before deploying:
+```bash
+docker compose exec terra-view python3 backend/migrate_add_allocated.py
+docker compose exec terra-view python3 backend/migrate_add_deployment_records.py
+```
+
+---
+
+## [0.9.1] - 2026-03-20
+
+### Fixed
+- **Location slots not persisting**: Empty monitoring location slots (no unit assigned yet) were lost on save/reload. Added `location_slots` JSON column to `job_reservations` to store the full slot list including empty slots.
+- **Modems in Recent Alerts**: Modems no longer appear in the dashboard Recent Alerts panel — alerts are for seismographs and SLMs only. Modem status is still tracked internally via paired device inheritance.
+- **Series 4 heartbeat `source_id`**: Updated heartbeat endpoint to accept the new `source_id` field from Series 4 units with fallback to the legacy field for backwards compatibility.
+
+### Migration Notes
+Run on each database before deploying:
+```bash
+docker compose exec terra-view python3 backend/migrate_add_location_slots.py
+```
+
+---
+
+## [0.9.0] - 2026-03-19
+
+### Added
+- **Job Planner**: Full redesign of the Fleet Calendar into a two-tab Job Planner / Calendar interface
+  - **Planner tab**: Create and manage job reservations with name, device type, dates, color, estimated units, and monitoring locations
+  - **Calendar tab**: 12-month rolling heatmap with colored job bars per day; confirmed jobs solid, planned jobs dashed
+  - **Monitoring Locations**: Each job has named location slots (filled = unit assigned, empty = needs a unit); progress shown as `2/5` with colored squares that fill as units are assigned
+  - **Estimated Units**: Separate planning number independent of actual location count; shown prominently on job cards
+  - **Fleet Summary panel**: Unit counts as clickable filter buttons; unit list shows reservation badges with job name, dates, and color
+  - **Available Units panel**: Shows units available for the job's date range when assigning
+  - **Smart color picker**: 18-swatch palette + custom color wheel; new jobs auto-pick a color maximally distant in hue from existing jobs
+  - **Job card progress**: `est. N · X/Y (Z more)` with filled/empty squares; amber → green when fully assigned
+  - **Promote to Project**: Promote a planned job to a tracked project directly from the planner form
+  - **Collapsible job details**: Name, dates, device type, color, project link, and estimated units collapse into a summary header
+  - **Calendar bar tooltips**: Hover any job bar to see job name and date range
+  - **Hash-based tab persistence**: `#cal` in URL restores Calendar tab on refresh; device type toggle preserves active tab
+  - **Auto-scroll to today**: Switching to Calendar tab smooth-scrolls to the current month
+  - **Upcoming project status**: New `upcoming` status for projects promoted from reservations
+- **Job device type**: Reservations carry a device type so they only appear on the correct calendar
+- **Project filtering by device type**: Projects only appear on the calendar matching their type (vibration → seismograph, sound → SLM, combined → both)
+- **Confirmed/Planned toggles**: Independent show/hide toggles for job bar layers on the calendar
+- **Cal expire dots toggle**: Calibration expiry dots off by default, togglable
+
+### Changed
+- **Renamed**: "Fleet Calendar" / "Reservation Planner" → **"Job Planner"** throughout UI and sidebar
+- **Project status dropdown**: Inline `<select>` in project header for quick status changes
+- **"All Projects" tab**: Shows everything except deleted; default view excludes archived/completed
+- **Toast notifications**: All `alert()` dialogs replaced with non-blocking toasts (green = success, red = error)
+
+### Migration Notes
+Run on each database before deploying:
+```bash
+docker compose exec terra-view python3 -c "
+import sqlite3
+conn = sqlite3.connect('/app/data/seismo_fleet.db')
+conn.execute('ALTER TABLE job_reservations ADD COLUMN estimated_units INTEGER')
+conn.commit()
+conn.close()
+"
+```
+
+---
+
+## [0.8.0] - 2026-03-18
+
+### Added
+- **Watcher Manager**: New admin page (`/admin/watchers`) for monitoring field watcher agents
+  - Live status cards per agent showing connectivity, version, IP, last-seen age, and log tail
+  - Trigger Update button to queue a self-update on the agent's next heartbeat
+  - Expand/collapse log tail with full-log expand mode
+  - Live surgical refresh every 30 seconds via `/api/admin/watchers` — no full page reload, open logs stay open
+
+### Changed
+- **Watcher status logic**: Agent status now reflects whether Terra-View is hearing from the watcher (ok if seen within 60 minutes, missing otherwise) — previously reflected the worst unit status from the last heartbeat payload, which caused false alarms when units went missing
+
+### Fixed
+- **Watcher Manager meta row**: Dark mode background was white due to invalid `dark:bg-slate-850` Tailwind class; corrected to `dark:bg-slate-800`
+
+---
+
+## [0.7.1] - 2026-03-12
+
+### Added
+- **"Out for Calibration" Unit Status**: New `out_for_cal` status for units currently away for calibration, with visual indicators in the roster, unit list, and seismograph stats panel
+- **Reservation Modal**: Fleet calendar reservation modal is now fully functional for creating and managing device reservations
+
+### Changed
+- **Retire Unit Button**: Redesigned to be more visually prominent/destructive to reduce accidental clicks
+
+### Fixed
+- **Migration Scripts**: Fixed database path references in several migration scripts
+- **Docker Compose**: Removed dev override file from the repository; dev environment config kept separate
+
+### Migration Notes
+Run the following migration script once per database before deploying:
+```bash
+python backend/migrate_add_out_for_calibration.py
+```
+
+---
+
+## [0.7.0] - 2026-03-07

+  - Accepts `.rnd`/`.rnh` files; parses `.rnh` metadata for session start/stop times, serial number, and store name
+  - Creates `MonitoringSession` and `DataFile` records automatically; no unit assignment required
+  - Upload panel on NRL detail Data Files tab with inline feedback and auto-refresh via HTMX
+- **Standalone SLM Type**: New SLM device mode that operates without a modem (direct IP connection)
+- **NL32 Data Support**: Report generator and web viewer now support NL32 measurement data format
+- **Combined Report Wizard**: Multi-session combined Excel report generation tool
+  - Wizard UI grouped by location with period type badges (day/night)
+  - Each selected session produces one `.xlsx` in a ZIP archive
+  - Period type filtering: day sessions keep last calendar date (7AM–6:59PM); night sessions span both days (7PM–6:59AM)
+- **Combined Report Preview**: Interactive spreadsheet-style preview before generating combined reports
+- **Chart Preview**: Live chart preview in the report generator matching final report styling
+- **SLM Model Schemas**: Per-model configuration schemas for NL32, NL43, NL53 devices

+
+### Changed
+- **MonitoringSession rename**: `RecordingSession` renamed to `MonitoringSession` throughout codebase; DB table renamed from `recording_sessions` to `monitoring_sessions`
+  - Migration: `backend/migrate_rename_recording_to_monitoring_sessions.py`
+- **Combined Report Split Logic**: Separate days now generate separate `.xlsx` files; NRLs remain one per sheet
+- **Mass Upload Parsing**: Smarter file filtering — no longer imports unneeded Lp files or `.xlsx` files
+- **SLM Start Time Grace Period**: 15-minute grace window added so data starting at session start time is included
+- **NL32 Date Parsing**: Date now read from `start_time` field instead of file metadata
+- **Project Data Labels**: Improved Jinja filters and UI label clarity for project data views
+
+### Fixed
+- **Dev/Prod Separation**: Dev server now uses Docker Compose override; production deployment no longer affected by dev config
+- **SLM Modal**: Bench/deploy toggle now correctly shown in SLM unit modal
+- **Auto-Downloaded Files**: Files downloaded by scheduler now appear in project file listings
+- **Duplicate Download**: Removed duplicate file download that occurred following a scheduled stop

+- `device_model` stored on `monitoring_sessions` table (migration: `migrate_add_session_device_model.py`)
+- Upload endpoint: `POST /api/projects/{project_id}/nrl/{location_id}/upload-data`
+- ZIP filename format: `{session_label}_{project_name}_report.xlsx` (label first)
+
+### Migration Notes
+Run the following migration scripts once per database before deploying:
+```bash
+python backend/migrate_rename_recording_to_monitoring_sessions.py
+python backend/migrate_add_session_period_type.py
+python backend/migrate_add_session_device_model.py

+
+## [0.6.1] - 2026-02-16
+
+### Added
+- **One-Off Recording Schedules**: Support for scheduling single recordings with specific start and end datetimes
+- **Bidirectional Pairing Sync**: Pairing a device with a modem now automatically updates both sides, clearing stale pairings when reassigned
+- **Auto-Fill Notes from Modem**: Notes are now copied from modem to paired device when fields are empty
+- **SLMM Download Requests**: New `_download_request` method in SLMM client for binary file downloads with local save
+
+### Fixed
