docs: expand cache plan with all seven testing tiers and do…
Sonnet 4.6

| 1 | """Comprehensive hardening tests for ``muse pull``. |
| 2 | |
| 3 | Covers all changes introduced in the pull command review: |
| 4 | |
| 5 | Unit |
| 6 | ---- |
| 7 | - Parser flags: --ff-only, --dry-run, --json/-j |
| 8 | - Dead-code removal: _current_branch and _restore_from_manifest absent |
| 9 | - _PullJson TypedDict keys complete |
| 10 | - _negotiate_have: exhausted-without-base falls back to full list |
| 11 | - _negotiate_have: ready on first round returns ack |
| 12 | |
| 13 | Integration (mocked transport) |
| 14 | ------------------------------- |
| 15 | - All error messages routed to stderr |
| 16 | - remote not configured → stderr + exit 1 |
| 17 | - branch not on remote → stderr + exit 1 |
| 18 | - fetch TransportError → stderr + exit 1 (INTERNAL_ERROR) |
| 19 | - unknown flag → non-zero exit |
| 20 | - up_to_date JSON schema complete |
| 21 | - fast_forward JSON schema complete |
| 22 | - merged JSON schema complete |
| 23 | - conflict JSON schema complete (exit 2) |
| 24 | - fetched JSON schema complete (--no-merge) |
| 25 | - dry_run JSON schema complete |
| 26 | - --ff-only: diverged branches refuse pull, exit 1 |
| 27 | - --ff-only: fast-forward still succeeds |
| 28 | - "Already up to date" goes to stderr, not stdout |
| 29 | - apply_manifest called BEFORE write_branch_ref in fast-forward |
| 30 | - commits_received uses commits_written from apply_mpack result |
| 31 | |
| 32 | End-to-end (file:// transport) |
| 33 | -------------------------------- |
| 34 | - Fresh pull into empty local |
| 35 | - Fast-forward pull after remote advances |
| 36 | - --no-merge stops at fetch |
| 37 | - --dry-run produces no side effects |
| 38 | - --json produces valid parseable output |
| 39 | |
| 40 | Security |
| 41 | -------- |
| 42 | - remote name ANSI-sanitized in all errors |
| 43 | - branch name ANSI-sanitized in all errors |
| 44 | - conflict path ANSI-sanitized in text output |
| 45 | - invalid --format exits to stderr |
| 46 | - progress to stderr, stdout clean on --json |
| 47 | |
| 48 | Stress |
| 49 | ------ |
| 50 | - _negotiate_have with 10 000 synthetic commits: terminates |
| 51 | - concurrent independent _negotiate_have calls |
