+# Agent Instructions
+
+This project uses **bd** (beads) for issue tracking. Run `bd onboard` to get started.
+
+## Quick Reference
+
+```bash
+bd ready              # Find available work
+bd show <id>          # View issue details
+bd update <id> --status in_progress  # Claim work
+bd close <id>         # Complete work
+bd sync               # Sync with git
+```
+
+## Landing the Plane (Session Completion)
+
+**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
+
+**MANDATORY WORKFLOW:**
+
+1. **File issues for remaining work** - Create issues for anything that needs follow-up
+2. **Run quality gates** (if code changed) - Tests, linters, builds
+3. **Update issue status** - Close finished work, update in-progress items
+4. **PUSH TO REMOTE** - This is MANDATORY:
+   ```bash
+   git pull --rebase
+   bd sync
+   git push
+   git status  # MUST show "up to date with origin"
+   ```
+5. **Clean up** - Clear stashes, prune remote branches
+6. **Verify** - All changes committed AND pushed
+7. **Hand off** - Provide context for next session
+
+**CRITICAL RULES:**
+- Work is NOT complete until `git push` succeeds
+- NEVER stop before pushing - that leaves work stranded locally
+- NEVER say "ready to push when you are" - YOU must push
+- If push fails, resolve and retry until it succeeds

+## Project Overview
+
+PyJHora is a complete Vedic Astrology Python package based on "Vedic Astrology - An Integrated Approach" by PVR Narasimha Rao and Jagannatha Hora V8.0 software. It provides panchanga calculations, horoscope charts, 40+ dasha systems, 100+ yogas, and PyQt6-based GUIs.
+
+## Build and Test Commands
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Install package in development mode
+pip install -e .
+
+# Run all tests (~6500 tests, assumes Lahiri ayanamsa)
+# Tests use custom framework, not pytest
+python -c "
+import sys; sys.path.insert(0, 'src')
+from jhora import utils
+utils.set_language('en')
+from jhora.tests import pvr_tests
+pvr_tests.all_unit_tests()
+"
+
+# Run subset of tests (edit some_tests_only() in pvr_tests.py to select)
+python -c "
+import sys; sys.path.insert(0, 'src')
+from jhora import utils
+utils.set_language('en')
+from jhora.tests import pvr_tests
+pvr_tests.some_tests_only()
+"
+```
+
+## Key Architecture
+
+### Core Modules (`src/jhora/`)
+
+- **`const.py`**: All constants - planet IDs (SUN=0 to KETU=8, URANUS=9, NEPTUNE=10, PLUTO=11), house numbers (HOUSE_1=0 to HOUSE_12=11), rasi names (ARIES=0 to PISCES=11), 20+ ayanamsa modes (Lahiri default)
+- **`utils.py`**: Helper functions for geolocation, timezone, Julian day conversion, language support (`set_language()`)
+
+### Panchanga (`jhora/panchanga/`)
+
+- **`drik.py`** (183KB): Main panchanga functions - sunrise/set, tithi, nakshatra, yogam, karana, planet positions, special lagnas, upagrahas. This is the astronomical calculation engine.
+- **`vratha.py`**: Special day calculations (amavasya, ekadashi, etc.)
+
+### Horoscope (`jhora/horoscope/`)
+
+- **`main.py`** (128KB): Main `Horoscope` class orchestrating all features
+- **`chart/charts.py`** (142KB): Divisional charts (D-1 to D-300), bhava calculations, 17 house systems
+- **`chart/yoga.py`** (364KB): 100+ yoga calculations
+- **`chart/house.py`** (71KB): Aspects, drishti, karakas, stronger planet/rasi calculations
+- **`dhasa/graha/`**: 22 graha dasha systems (vimsottari, ashtottari, yogini, etc.)
+- **`dhasa/raasi/`**: 22 rasi dasha systems (narayana, chara, kalachakra, etc.)
+
+### UI (`jhora/ui/`)
+
+- **`horo_chart_tabs.py`**: Main multi-tab UI with 100+ pages of data
+- **`panchangam.py`**: Simple panchanga UI widget
+- **`chart_styles.py`**: South/North/East Indian chart widgets
+
+## Data Structures
+
+Planet positions: `[[planet_index, (rasi, longitude)], ...]`
+
+Charts/houses: `['', '', '2', '7', '1/5', ...]` (planets in each house)
+
+Key namedtuples in utils: `Date`, `Place`
+
+## Language Support
+
+6 languages via JSON files in `lang/`: 'en', 'hi', 'ka', 'ml', 'ta', 'te'
+
+Switch with `utils.set_language('ta')`
+
+## External Dependencies
+
+- **pyswisseph**: Swiss Ephemeris for celestial calculations (required)
+- **PyQt6**: GUI framework
+- **geopy/timezonefinder**: Geolocation and timezone detection
+
+## Important Notes
+
+- Tests assume `const._DEFAULT_AYANAMSA_MODE='LAHIRI'`
+- Ephemeris files in `data/ephe/` required for calculations (JPL compressed)
+- Accuracy: 13000 BCE to 16800 CE (Swiss Ephemeris range)
+- Some modules marked experimental: `prediction/`, `surya_sidhantha.py`, `khanda_khaadyaka.py`
