# F1 22 / ACC Telemetry Analyzer

Turns raw F1 22 and Assetto Corsa Competizione lap telemetry into compact Markdown reports you can paste into an LLM for analysis. A full raw lap is ~1M tokens; these reports are 1–35k.

```bash
# from the tool/ folder
python -m telemetry technique "races/Zandvoort/Practice/zandvoort_P1_L7_74.074_ferrari.csv"
# -> races/Zandvoort/Practice/reports/zandvoort_P1_L7_74.074_ferrari_technique.md   (~35k tokens)
```

Or just double-click `run-gui.bat` and click **Generate report**.

## Install

- Python 3.10+ (uses only the standard library — no `pip install`).
- Tk is required for the GUI; it ships with the standard Python installer on Windows/macOS. The CLI works without it.

Download or clone the repository. Keep your telemetry CSVs in the parent folder of `tool/` (see [folder layout](#folder-layout)).

## What it does

Six modes. Five produce reports, one renames files. Both F1 22 and ACC (GT3/GT4) CSVs are supported — the game is detected automatically from each file's metadata.

| Mode | Input | Use it to analyse |
|------|-------|-------------------|
| `technique` | one lap | **how** you drive — braking points, apex speeds, throttle application, lockups, resource cost |
| `setup` | one lap | **what** is set — balance (US/OS), tyre temps, brakes, suspension rake & roll |
| `compare` | two+ laps | **where** one lap is faster — per-corner and cumulative delta, plus a deterministic `Verdict` (fuel-corrected) |
| `race` | a folder of laps | the whole race — pace, stint degradation, tyre wear, ERS per lap (F1) |
| `profile` | a folder of laps | **cheap** (~400 tokens) cross-lap driver tendencies per tyre compound (median coast/lock/spin per corner, flagged relative to the session) + auto-picked laps to deep-dive. Track-agnostic: corners are clustered by apex distance, not index |
| `rename` | files/folder | insert session type and lap number into each filename (`..._74.074_...` → `..._P1_L7_74.074_...`) |

Reports include a legend explaining every column and have the analysis prompt auto-appended at the end — just drop the file into an LLM. Prompts come in RU and EN; pick with `--lang en` on the CLI or the language radio in the GUI.

**Flags:** `--no-prompt` omits the embedded analysis prompt (smaller files for agent pipelines; in the GUI it's the **Include prompt** checkbox). `--force` regenerates even when an up-to-date report already exists (runs are otherwise skipped as `cached`). `--game {auto,f1,acc}` overrides the auto-detected game (default `auto`).

> Typical optimized flow: run `profile` first to see chronic tendencies and which laps matter, then generate `technique`/`setup`/`compare` only for those laps with `--no-prompt`.

### ACC vs F1 22 differences

GT3/GT4 cars have no hybrid system, and ACC does not export the car setup:

- `technique` and `race` reports omit the DRS / ERS / MGU-K sections.
- `setup` mode: ACC's in-game setup export is all zeros, so the parameter table is replaced by a note ("ACC does not export setup — analysis derived from telemetry"); the telemetry-derived sections (corner balance, tyres, brakes, suspension) are retained.
- Fuel is in **litres** (GT) rather than kg (F1). Tyres are Pirelli dry/wet compounds, not F1 C1–C5.

## Handy things

**GUI** — double-click `run-gui.bat` (or `run-gui.pyw` for no console window, or run `python -m telemetry gui`). The window has two tabs — **F1 22** and **ACC** — each with its own independent controls and log. Pick a mode and language (RU/EN), browse to the file/folder, click Generate. The file browser remembers the last used directory per mode. The **Rename unprocessed** button adds the session type and lap number to files that don't have them yet and leaves the rest alone. If a file's detected game doesn't match the active tab, the GUI logs a warning but proceeds.

**CLI** — from the `tool/` folder:

```bash
python -m telemetry technique races/Zandvoort/Practice/lap.csv
python -m telemetry setup     races/Zandvoort/Practice/lap.csv
python -m telemetry compare   races/Zandvoort/Practice/lap_a.csv races/Zandvoort/Practice/lap_b.csv
python -m telemetry race      races/Zandvoort/Race
python -m telemetry profile   races/Zandvoort/Race        # cheap cross-lap tendencies + lap picks
python -m telemetry rename    races/Zandvoort/Practice   # or individual files

# choose prompt language (default: ru)
python -m telemetry technique races/Zandvoort/Practice/lap.csv --lang en

# override game detection (default: auto)
python -m telemetry technique ACC/races/Hungaroring/Practice/lap.csv --game acc

# agent pipeline: drop the prompt, reuse fresh reports
python -m telemetry technique races/Zandvoort/Practice/lap.csv --no-prompt
python -m telemetry technique races/Zandvoort/Practice/lap.csv --force   # ignore cache
```

Every report run prints the output path and a token estimate:

```
C:\...\Telemetry\reports\lap_technique.md
~33834 tokens (budget 60k)
```

**Rename inserts tokens AND sorts into folders.** Point it at a folder containing CSVs (e.g., `D:\Games\Telemetry\Data\lapdata\f1_2022`) — the script:
- Recursively scans all subdirectories
- Reads metadata from each CSV (track, session type)
- Inserts `P1_L7` into filenames that don't have both tokens yet
- Moves files to `races/<track>/Practice|Qualifying|Race/`
- Even already-renamed files are moved if they're not in the right folder
- Only skips files that are already in the correct location with the correct name

Re-running on the same folder is safe — in-place files are left alone.

## Input format

F1 22 UDP telemetry or ACC telemetry, both exported to CSV (F1 22 tested with [F1Laps](https://www.f1laps.com)). UTF-8, 108 channels, one file = one lap (F1 22 is ≈1800 rows/lap at ≈29 Hz; ACC laps are denser, ~14k rows — reports stay compact via adaptive resampling). For `race` mode, drop all of a race's lap files into one folder. The CSV format is identical between F1 22 and ACC; the game is detected from the `Game` metadata field in each file.

## For developers

Pure-stdlib Python. Pipeline: `parser` → `segments` (+ `corner_metrics`) → `resample` → `report_*`. See [ARCHITECTURE.md](ARCHITECTURE.md).

```bash
cd tool
python -m pytest -q        # run the test suite
python -m telemetry gui    # launch the GUI
```

Adding a mode: drop a `telemetry/report_<mode>.py` exposing `generate(...) -> (abs_path, tokens)` and wire one line into `telemetry/__main__.py`. The parser, corner detection, adaptive trace, and shared report blocks are reused.
