HTTP error classification and target modeling for scanner feedback loops.
Documentation
# Contributing to erroracle

## Getting started

1. Install Rust with `rustup`.
2. `cd /home/mukund-thiru/Santh/libs/erroracle`.
3. Run `cargo check` and `cargo test`.

## Development expectations

- Keep the crate independent of any scanner runtime.
- Add tests for new classification or parsing branches.
- Preserve deterministic schema-learning behavior.
- Keep follow-up generation focused on payload construction, not request transport.

## Testing

- `cargo check`
- `cargo test`
- `cargo test -- --nocapture`

## PR checklist

- [ ] New heuristics have regression tests
- [ ] Public API remains target-agnostic
- [ ] README examples still compile
