# Terminal E2E artifacts

`zig build terminal-e2e` runs `tools/terminal_e2e.py` against the compiled `mim`
binary and writes ignored artifacts under `.zig-cache/terminal-e2e/<scenario>/`.

Artifact roles:

- `manifest.tsv`: stable scenario facts, hashes, bare-LF status, and artifact list.
- `visible-controls.normalized.txt`: primary semantic failure artifact. It shows
  CR as `␍`, LF as `␊`, ESC as `␛`, tabs as `⇥`, and normalizes volatile temp
  paths.
- `transcript.txt`: semantic terminal grid after escape/control interpretation.
- `screenshot.svg` and `terminal.html`: browser-viewable visual evidence.
- `raw.bin`: exact PTY bytes for low-level debugging.

Golden policy:

- Investigate before updating any expected artifact or assertion.
- Prefer semantic artifacts (`manifest.tsv`, `visible-controls.normalized.txt`,
  `transcript.txt`) for assertions; visual artifacts explain what a user would
  see.
- Updating artifacts is safe only after the change is intentional and the receipt
  names the changed UI/control-byte behavior.
- Bare LF in raw-mode terminal output is a regression unless a scenario explicitly
  proves a non-raw stream. Raw-mode rendering should use CRLF to avoid diagonal
  terminal skew.
- Generated artifacts must remain under ignored build output and must not dirty a
  clean source tree.
