Hooks a recorder into the command chokepoint so each run is written to disk as it plays, ready for playback in Phase 3. - ReplayRecorder (lib): line-oriented append-friendly file — keyed header (version, build, seed, config_hash, timestamp), then '---', then tick-tagged command lines interleaved with "# checksum <tick> <hex>" RNG fingerprints. Each line is flushed so a crash leaves a valid partial file. Config hash is a 64-bit FNV over the config dir's *.toml files; build tag is __DATE__/__TIME__. - CommandSerializer (lib): per-command text (length-prefixed variable parts; ship layouts and splitter filters serialized inline). Reset is a file boundary, never a stream entry. - CommandManager owns an optional ReplayRecorder: drain() records each applied command + a post-apply checksum; a drained Reset rolls to a new file; recordTickCheckpoint() (called per tick from onFrame) writes a checksum every 30 ticks. - Random seed generated in main and on restart (std::random_device); Simulation retains it via getSeed() for the header. - GameWorldView attaches the recorder at construction (first file + tick-0 checksum); replays land in <data>/replays named <timestamp>_<seed>.replay. ReplayRecorderTest covers serialization, file well-formedness, file rolling, and the CommandManager drain->record integration. Full suite green (346 cases / 3377 assertions); app, tests, and balancing all build.
