docs: expand cache plan with all seven testing tiers and do…
Sonnet 4.6
131 days ago
| 1 | """Tests for ``muse cat`` — file-level, domain-agnostic content reader. |
| 2 | |
| 3 | ``muse cat`` is the core-VCS primitive: give me the raw bytes of a tracked |
| 4 | file at HEAD or any ref. It does not parse symbols — that is ``muse code cat``. |
| 5 | Mirrors the relationship between ``muse blame`` (line-level) and |
| 6 | ``muse code blame`` (symbol-level). |
| 7 | |
| 8 | 7-tier coverage |
| 9 | --------------- |
| 10 | Unit argument parsing, address validation (:: rejected) |
| 11 | Integration single file, multi-file, --at ref, --json schema |
| 12 | E2E historical ref shows old content; working-tree shows new |
| 13 | Security symlink rejected, path traversal rejected, ANSI in path |
| 14 | Stress large file (1 MiB) completes fast |
| 15 | Data integrity JSON content == disk bytes; --at content != HEAD content |
| 16 | Performance single file < 0.3s; multi-file 10 files < 1s |
