 ## Project Overview
 
 Look4Sat is an open-source, fully offline Android satellite tracker and pass predictor. It tracks 9000+ active
-satellites using TLE/OMM data from Celestrak/SatNOGS, calculates orbital positions via SGP4/SDP4 models, and displays
-passes relative to the user's location. Features include polar radar visualization, SSTV image decoding, satellite
-ground track mapping, and pass predictions up to 10 days ahead. No ads, no tracking, no network required after initial
-data download.

 ## Data Formats & Migration
 
-**TLE vs. OMM/CSV format:**
+Look4Sat supports both TLE and OMM (Orbit Mean-Elements Message) CSV formats:
 
-Look4Sat supports both TLE and OMM (Orbit Mean-Elements Message) formats for backward compatibility:
+- **TLE format**: Legacy 3-line element format limited by 5-digit NORAD IDs
+- **OMM/CSV format**: Successor format with ISO 8601 timestamps and larger NORAD ID support
+- New 5-digit NORAD IDs are exhausted; TLE is officially deprecated and OMM/CSV is the clear default
+- `DataParser.kt` supports both via `parseTLEStream()` and `parseCSVStream()`
+- Downloads auto-detect format; both produce identical `OrbitalData` objects
+- Existing code already supports transparent source transition without feature changes
+- Refresh orbital data weekly for accurate pass prediction (orbital decay)
 
-- **TLE format**: Traditional 3-line element format (deprecated). NORAD catalog numbers are 5-digit integers, which
-  are running out of space. Celestrak has signaled that TLE format will eventually be phased out.
-- **OMM/CSV format**: The future standard. CSV files contain the same orbital parameters as TLE but use ISO 8601
-  timestamps and support larger NORAD IDs. Celestrak and SatNOGS already provide OMM data in CSV format.
+## Engineering Heuristics (Lazy = Efficient)
 
-**Current implementation:**
-- `DataParser.kt` handles both `parseTLEStream()` and `parseCSVStream()` seamlessly
-- TLE data is downloaded from configured sources and stored in Room database
-- When downloading satellite data, the app automatically detects format and parses accordingly
-- Both formats produce identical `OrbitalData` objects, ensuring transparent format switching
+- Treat "lazy" as efficient, not careless: the best code is the code never written.
+- First understand the task and trace the real flow end-to-end, then climb this ladder:
+  1. Does this need to be built now? (YAGNI)
+  2. Does it already exist in this codebase? Reuse helpers/patterns before rewriting.
+  3. Does Kotlin/Java stdlib already solve it?
+  4. Does the Android/platform API already solve it?
+  5. Does an already-installed dependency solve it?
+  6. Can this be simpler (including one-liner simple)?
+  7. Only then: write the minimum code that works.
+- Prefer deletion to addition, boring over clever, and the fewest touched files.
+- Avoid new abstractions, dependencies, and boilerplate unless explicitly requested.
+- Manual DI only: ViewModels use companion `factory()` methods with `IMainContainer`.
+- Release builds use ProGuard: avoid reflection-heavy libraries unless explicitly approved.
+- When two options are similar in size, choose the edge-case-correct one.
+- If you keep a deliberate simplification (for example O(n^2) scan or global lock), leave a short comment with the ceiling and upgrade path.
+- For complex asks, challenge scope when appropriate: "Do you need X, or does Y already cover it?"
 
-**Migration path:**
-As NORAD catalog space becomes constrained, OMM/CSV will become the primary format. Look4Sat is already positioned
-to handle this transition without code changes — existing users can continue using TLE files while new sources
-transition to OMM/CSV automatically.
+## Bug-Fix Policy
 
-## Code Style
-
-- Prefer **short, focused functions** — single responsibility, easy to read.
-- **Exceptions**: Composable functions and math-heavy algorithms (SGP4/SDP4) may be longer.
-- Strict code style — no dead code, no unused imports, consistent formatting.
+- Fix root cause, not just the reported symptom.
+- If touching a shared function, inspect callers and prefer one shared fix over per-caller patches.
+- The smallest correct diff wins only after behavior is understood.

 ## Gotchas
 
-- Orbital math lives in `core:domain/predict/` — it's dense vector math (SGP4/SDP4). Tread carefully.
-- TLE/OMM data must be refreshed weekly for accurate predictions (satellite orbits decay). TLE format is legacy and
-  will eventually be deprecated in favor of OMM/CSV as NORAD catalog numbers approach the 5-digit limit.
+- Orbital math lives in `core:domain/predict/` — dense vector math (SGP4/SDP4). Tread carefully.
 - SSTV decoding in `feature:radar` is experimental; image quality depends on signal strength during satellite pass.

-- ProGuard is enabled for release builds — don't add reflection-based libs or any other dependencies without asking.

- * Only QSL_RCVD=Y records are returned by LoTW for qso_qsl=yes, so every grid in the

- * ARRL rate-limits the report endpoint: one download in progress per user id, and
- * frequent full-report pulls get refused. Failures are reported with an explicit
