 - Config is read from disk; it is not event-sourced. Do not add event/state/reducer structures here.
 - `ConfigHolder` is the shared mutable reference injected into consumers. Never read the file directly in domain code — always go through `ConfigHolder`.
 - `CorrexConfigWriter` regenerates TOML from the in-memory model; round-tripping loses comments by design.
+- `[git]` is opt-in server transport configuration (`enabled`, `remote`, `base_branch`, optional `author`); it is off by default.
+- `ModelConfig.contextSize` defaults to 24,576 tokens; explicit `context_size` remains the operator override for smaller local-model windows.
