  ════════════════════════════════════════════════════════════════════════════

KEY FINDINGS:

1. ARCHITECTURE ✅
   - Uses clap-noun-verb v3.4.0 for auto-discovery
   - Clean #[verb] macro pattern (all except CI)
   - Proper async/sync bridge with block_on()
   - Centralized error handling (ggen-utils::error)
   - JSON-serializable output structs

2. DOCUMENTED vs IMPLEMENTED ⚠️
   - ❌ ggen ai generate-ontology (mentioned in README, NOT implemented)
   - ✅ ggen template generate-rdf (implemented, fully working)
   - ✅ ggen project commands (mostly implemented)
   - ✅ ggen marketplace search/install (working)
   - ⚠️ Paper commands (9 verbs exist, mostly stubs)
   - ❌ Workflow commands (5 verbs, all stubs with demo output)

3. ERROR HANDLING ✅
   - No unwrap/expect/panic in production command paths
   - Consistent use of .map_err() patterns
   - Custom Error type with source chaining
   - Minor: Some defensive .unwrap_or_else() could be simplified

4. INCOMPLETE IMPLEMENTATIONS:
   
   HIGH PRIORITY:
   - paper::compile - Returns 0KB, no pdflatex execution
   - paper::generate - Placeholder output only
   - workflow::* - All 5 return hardcoded demo data
   - marketplace::list - Maturity filtering documented but not implemented
   - template::regenerate - Merge strategies unimplemented
   - project::watch - Blocking operation (architectural issue)

   LOWER PRIORITY:
   - paper validation - File existence check only
   - CI commands - Uses legacy Subcommand enum (not #[verb])
   - Paper submission tracking - Draft status only

COMMAND GROUPING BY STATUS:

FULLY FUNCTIONAL (13 commands):
├─ ai: generate, chat, analyze
├─ graph: load, query, export, visualize  
├─ hook: create, list, remove, monitor
├─ utils: doctor, env
└─ template: show, new, list, lint, generate, generate-rdf

MOSTLY WORKING (14 commands):
├─ template: generate-tree (placeholder)
├─ template: regenerate (stub)
├─ project: new, plan, gen, apply, init, generate (all working)
├─ project: watch (blocking issue)
└─ marketplace: search, install, list, publish, validate, maturity, dashboard

STUB/INCOMPLETE (17 commands):
├─ marketplace: generate-artifacts, maturity-filtering, sorting (incomplete)
├─ paper: all 9 (mostly demo output)
├─ workflow: all 5 (hardcoded demo)
└─ ci: 1 (legacy pattern)

CLI ENTRY POINT:
  ggen binary
    └─> main.rs (simple wrapper)
        └─> ggen_cli_lib::cli_match()
            └─> clap_noun_verb::run() [auto-discovery]
                └─> cmds/ modules
                    └─> domain layer (async logic)

RUNTIME PATTERN:
  All verbs follow: async domain logic wrapped in block_on()
  Returns clap_noun_verb::Result<T> where T: Serialize
  
  Example:
    #[verb]
    fn command() -> Result<Output> {
        block_on(async { domain::execute(...).await })
    }

ERROR HANDLING PATTERN:
  .map_err(|e| NounVerbError::execution_error(e.to_string()))
  ✅ No panics in CLI layer
  ✅ Proper error propagation
  ⚠️ Placeholder implementations don't return real errors
