# Runbook — build and validation commands

Reusable validation steps for this repository. Run the relevant ones before
considering a change complete.

## Build and test

```sh
meson setup build          # once
meson compile -C build
meson test -C build --print-errorlogs
```

## Memory and correctness checks (codec changes)

Run the codec round-trip test under valgrind after touching the encoder or
decoder:

```sh
valgrind --leak-check=full --errors-for-leak-kinds=definite \
    build/tests/test_codec_roundtrip
```

Expected: no "definitely lost" bytes and no "Invalid read/write" errors.
FFmpeg may keep some "still reachable" allocations at exit; that is normal.

This check caught two real defects in the Phase 2 decoder: a per-packet
payload leak and an unpadded extradata buffer over-read. Keep using it.

## Formatting

```sh
find include src tests -type f \( -name '*.cpp' -o -name '*.h' \) \
    -exec clang-format --dry-run --Werror {} +
```
