| Scenario                                       | Test                                                 | Result                                                                                                                                                                                |
|------------------------------------------------|------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| S1: Valid catalog index parsed successfully    | `catalog::tests::parse_valid_index_with_skills`      | ✅ COMPLIANT                                                                                                                                                                           |

| S3: Index with missing required field rejected | `catalog::tests::parse_index_missing_required_field` | ⚠️ PARTIAL — tests missing `generated_at` in meta, not missing `content_hash` on a skill entry as spec requires. `content_hash` is `Option<String>` so missing it won't fail parsing. |

## Correctness (Static — Structural Evidence)

| Requirement                           | Status        | Notes                                                                                                                             |
|---------------------------------------|---------------|-----------------------------------------------------------------------------------------------------------------------------------|
| R7.1 CatalogIndex structure           | ⚠️ Partial    | `CatalogMeta.commit` is `Option<String>` (spec: required). Extra `repo_url` field and `name` field in `CatalogEntry` not in spec. |
| R7.2 CatalogEntry fields              | ⚠️ Partial    | `version` and `content_hash` are `Option<String>` — spec says required. Missing required field won't cause parse error.           |
| R7.3 Parseability                     | ✅ Implemented | Uses `toml` crate, no network.                                                                                                    |
| R8.1 Build-time embedding             | ✅ Implemented | `build.rs` copies file, `include_str!` embeds it.                                                                                 |
| R8.2 Lazy parsing                     | ✅ Implemented | `EMBEDDED_INDEX` is a `&str` const, parsed only on first catalog operation.                                                       |
| R8.3 Cached index with TTL            | ✅ Implemented | `resolve_index()` with cache → fetch → embedded chain. TTL configurable.                                                          |
| R8.4 Fallback chain                   | ✅ Implemented | Graceful error on all paths, no panics.                                                                                           |
| R9.1 Bare-name detection              | ✅ Implemented | `is_bare_name()` checks for absence of `/`, `\`, `.`, `:`.                                                                        |
| R9.2 Catalog resolution               | ✅ Implemented | `handle_catalog_install()` resolves from index.                                                                                   |
| R9.3 Official source and trust        | ✅ Implemented | Sets `SkillSource::Official`, no trust gate.                                                                                      |
| R9.4 Catalog miss                     | ✅ Implemented | Error with suggestions (search/URL).                                                                                              |

| R10.3 SkillForge SKILL.md only        | ✅ Implemented | `integrate.rs` generates only SKILL.md with frontmatter.                                                                          |
| R10.4 Continued SKILL.toml support    | ✅ Implemented | `load_skill_toml()` still works.                                                                                                  |
| R11.1 Discover command                | ✅ Implemented | `handle_discover_command()` queries GitHub.                                                                                       |
| R11.2 No auto-installation            | ✅ Implemented | Discover only displays results.                                                                                                   |

| R12.5 Summary report                  | ⚠️ Partial    | Uses `unchanged` field instead of `verified`.                                                                                     |

## Issues Found

### CRITICAL (must fix before archive)

1. **Update command routing is broken** — `skills/mod.rs:571-573` stubs out `SkillCommands::Update`
   with `println!("Update not yet implemented: {name:?}")` instead of calling the fully-implemented
   `handle_update_command()` at line 1236. All R13 scenarios (S28-S34) are unreachable. **Fix**:
   replace the stub with `handle_update_command(workspace_dir, name.as_deref())`.

2. **`load_skill_md` ignores parsed frontmatter fields** — `skills/mod.rs:380-395` hardcodes
   `version: "0.1.0"`, `author: None`, `tags: Vec::new()` instead of using `fm.version`,
   `fm.author`, `fm.tags` from the parsed frontmatter. This means R10.1 frontmatter fields are
   parsed but never used when loading skills. **Fix**: wire
   `fm.version.unwrap_or_else(|| "0.1.0".to_string())`, `fm.author`, `fm.tags` into the `Skill`
   struct.

### WARNING (should fix)

3. **CatalogEntry required fields are Optional** — `version: Option<String>` and
   `content_hash: Option<String>` in `CatalogEntry` should be required `String` per R7.2. A skill
   entry missing `content_hash` would parse successfully, violating S3. **Fix**: make these fields
   non-optional, or add post-parse validation.

4. **CatalogMeta.commit is Optional** — Spec R7.1 says `commit` is required. Code has
   `Option<String>`. **Fix**: make it a required `String` or add validation.

5. **RepairSummary field naming mismatch** — `RepairSummary.unchanged` should be `verified` per
   R12.5 spec. **Fix**: rename to `verified` for spec alignment.

6. **OFFICIAL_REPO constant is full URL** — Design contract says `"dallay/corvus-skills"` but code
   has `"https://github.com/dallay/corvus-skills"`. The `source_str` in `handle_catalog_install`
   strips the prefix with `trim_start_matches("https://github.com/")`, which is fragile. **Fix**:
   use the short identifier and construct the full URL when needed.

7. **Missing test coverage for 19 scenarios** — Tasks 4.2, 4.6, 4.7, 4.8 are not done. This leaves
   R8 (fallback chain), R12 (repair), and R9 (catalog install) scenarios without behavioral
   validation.

### SUGGESTION (nice to have)

8. **Task checkboxes out of sync** — Tasks 1.7, 4.4, 4.9 are done in code but not marked `[x]` in
   tasks.md.

9. **`search()` return type differs from design** — Design returns `Vec<(&String, &CatalogEntry)>`
   but implementation returns `Vec<&CatalogEntry>`. This is fine functionally since `CatalogEntry`
   now has a `name` field, but it deviates from the design contract.

10. **`CatalogEntry` has extra `name` field** — The design and spec don't include `name` in
    `CatalogEntry` (it's the key in the `BTreeMap`). The implementation adds it, which is redundant.
    Not a bug but creates data duplication.

## Verdict

### FAIL

The implementation is structurally complete for most requirements but has **two critical issues**
that prevent archive:

1. The `skills update` command is fully implemented but **not wired** — it prints a stub message
   instead of executing. This makes all R13 scenarios (7 of 38) unreachable dead code.

2. `load_skill_md` ignores the new frontmatter fields (`version`, `author`, `tags`), meaning the
   frontmatter extension (R10.1) is parsed but has **no runtime effect** on loaded skills.

Both fixes are small (< 5 lines each) but are blocking because they represent broken spec
requirements.

Additionally, 19 of 38 scenarios lack test coverage. While the code paths exist and are structurally
correct, the sdd-verify protocol requires passing tests as behavioral proof. The 4 missing test
tasks (4.2, 4.6, 4.7, 4.8) should be completed to bring compliance above the 50% threshold.

**Recommended next steps**:

1. Fix the Update routing (1-line change in `handle_command`)
2. Wire frontmatter fields into `load_skill_md` (3-line change)
3. Make `CatalogEntry.version` and `content_hash` required (or add validation)
4. Complete test tasks 4.2, 4.6, 4.7, 4.8 for scenario coverage
