# Deterministic fixtures

Fixtures in this directory are synthetic and safe to publish. They must never be
copied from real subscription transcripts, private repositories, shell history,
or credentials.

Planned fixture families:

- `harness/`: scripted child processes covering stdout, stderr, exit, signals,
  prompts, long lines, invalid UTF-8, backpressure, and process-tree cleanup.
- `acp/`: versioned initialize/session/prompt/cancel transcripts and capability
  combinations, including malformed and out-of-order frames.
- `terminal/`: compact VT byte streams with expected screen and scrollback state.
- `usage/`: provider-, harness-, measured-, and estimated-usage observations.
- `recovery/`: event logs ending at every externally visible interruption point.

Large generated corpora belong in release artifacts or a dedicated test-data
repository, not in normal Git history.
