VERDICT: PASS
|
|
|
|
## What was tested
|
|
|
|
### Stage 1: Compact dump output
|
|
|
|
**Guard checks (all passed):**
|
|
- `cstat dump --path .` produces valid JSON at 2,898 bytes (well under 10KB limit)
|
|
- All 6 top-level keys present: `cstat_version`, `project`, `scores`, `diagnostic_counts`, `worst_items`, `suggested_drilldowns`
|
|
- `worst_items` contains exactly 5 entries (capped correctly; verified with a synthetic 20-function project that generates 253 alerts — still capped at 5)
|
|
- Each `suggested_drilldowns` entry includes both `command` and `reason` fields
|
|
- `hotspots` and `topology` sections removed from output
|
|
- Full `diagnostics` array replaced with `diagnostic_counts`
|
|
|
|
**Drilldown logic verified:**
|
|
- Categories with alerts > 0 correctly map to their subcommands (complexity, redundancy, deps)
|
|
- Categories with 0 alerts (bloated_file, dead_code, too_many_params, high_coupling, cyclic_deps) correctly produce no drilldown entries
|
|
- Categories mapping to the same command are correctly merged with combined reasons
|
|
- Drilldowns are sorted by total alert count descending
|
|
|
|
**Boundary inputs:**
|
|
- Empty directory (no Cargo.toml): fails gracefully with "No Cargo.toml found" error message
|
|
- Nonexistent path: fails gracefully with "Cannot resolve path ... No such file or directory"
|
|
- Trivial single-function project: produces valid JSON with empty `worst_items` and empty `suggested_drilldowns`, zero diagnostics
|
|
- Malformed Rust source (syntax error): produces valid JSON, does not crash, reports 0 functions
|
|
|
|
**Subcommand compatibility:**
|
|
- All individual `--json` subcommands referenced in drilldown mappings produce valid JSON: `complexity`, `redundancy`, `deps`, `loc`, `datapaths`, `graph`
|
|
- `cstat summary` is untouched and renders correctly
|
|
|
|
### Stage 2: judge.md update
|
|
|
|
**Guard checks (all passed):**
|
|
- `judge.md` contains "## 3. Measure it" section
|
|
- References both `cstat dump --path .` and `cstat summary --path .`
|
|
- Frames metrics as "evidence, not as automatic pass/fail criteria"
|
|
|
|
### Code quality
|
|
|
|
- `dump.rs` (232 lines) is clean, well-structured, and easy to follow
|
|
- Clear naming: `DumpOutput`, `DiagnosticCounts`, `build_worst_items`, `build_drilldowns`, `category_name`
|
|
- Logical section separators with comments
|
|
- No TODOs, FIXMEs, debug prints, or dead code
|
|
- Not flagged in its own worst_items analysis
|
|
|
|
### Metrics (cstat on itself)
|
|
|
|
- Modularity: 0.92, Complexity: 0.81, Maintainability: 0.78
|
|
- All alert-level items are pre-existing large functions (diagnostics, summary, map) — not introduced by this change
|
|
- `dump.rs` does not appear in worst items
|
|
|
|
### Minor note (not blocking)
|
|
|
|
The `suggested_drilldowns` commands omit `--path .` (e.g., `cstat complexity --json` instead of `cstat complexity --json --path .`). The plan's example JSON includes `--path .`, but the mapping logic section does not. The commands are still usable — consumers just need to add their own `--path`. This is a cosmetic difference, not a functional one.
