docs: expand cache plan with all seven testing tiers and do…

| 1 | """Supercharged tests for ``muse bundle`` — three new agent-first features. |
| 2 | |
| 3 | Feature 1 — ``muse bundle inspect <file> [--json]`` |
| 4 | ----------------------------------------------------- |
| 5 | Read and display the commit log and branch state from a bundle file without |
| 6 | unbundling. No repository required. Agents use this to decide whether to |
| 7 | apply a bundle before committing to the operation. |
| 8 | |
| 9 | JSON schema:: |
| 10 | |
| 11 | { |
| 12 | "total_commits": int, |
| 13 | "total_objects": int, |
| 14 | "branches": {"<name>": "<commit_id>"}, |
| 15 | "commits": [ |
| 16 | { |
| 17 | "commit_id": str, |
| 18 | "message": str, |
| 19 | "committed_at": str, # ISO-8601 |
| 20 | "agent_id": str, # "" when not an agent commit |
| 21 | "branches": [str] # branch names whose head == this commit |
| 22 | }, |
| 23 | ... # newest first (by committed_at) |
| 24 | ] |
| 25 | } |
| 26 | |
| 27 | Feature 2 — ``--verify`` flag on ``muse bundle unbundle`` |
| 28 | ---------------------------------------------------------- |
| 29 | Verify bundle integrity atomically before applying. Exits 1 (with no |
| 30 | writes) if the bundle is corrupt. JSON output gains a ``"verified"`` bool. |
| 31 | |
| 32 | Feature 3 — ``muse bundle diff <file> [--json]`` |
| 33 | ------------------------------------------------- |
| 34 | Show which commits in the bundle are not already present in the local |
| 35 | repository. Agents use this to answer "what would this bundle add?" before |
| 36 | deciding to apply. |
| 37 | |
| 38 | JSON schema:: |
| 39 | |
| 40 | { |
| 41 | "new_commits": int, |
| 42 | "known_commits": int, |
| 43 | "refs_to_advance": [str], # branch names that would move |
| 44 | "commits": [ |
| 45 | {"commit_id": str, "message": str, "committed_at": str} |
| 46 | ] |
| 47 | } |
| 48 | |
| 49 | Test categories |
| 50 | --------------- |
| 51 | - unit : internal helpers and schema shapes |
| 52 | - integration : CLI flag parsing and output contracts |
| 53 | - e2e : full round-trips via CliRunner |
| 54 | - security : ANSI/control injection in bundle content |
| 55 | - data_integrity: inspect/diff remain consistent across create-verify-unbundle |
| 56 | - performance : inspect and diff on 100-commit bundles under 1 s |
| 57 | - stress : inspect and diff on 200-commit bundles |
