## Warnings

None.

### `.ok()` Usage Analysis

The following `.ok()` usages were reviewed and found acceptable:

| File:Line | Context | Verdict |
|-----------|---------|---------|
| `src/prerender/parent.rs:83` | Date parsing in `and_then` chain with `ok_or_else` fallback | ✅ Acceptable |
| `src/content/cards.rs:39` | After `inspect_err` logging, used in optional conversion | ✅ Acceptable |
| `src/prerender/index.rs:92` | Date parsing with proper error propagation via `ok_or_else` | ✅ Acceptable |
| `src/templates/html.rs:245` | URL parsing after `inspect_err` logging | ✅ Acceptable |
| `src/templates/paper.rs:31` | Frontmatter parsing after `inspect_err` logging | ✅ Acceptable |
| `src/build/validation.rs:93` | Filtering invalid URLs during validation | ✅ Acceptable |

## Tech Debt Items

None remaining.

## Architectural Compliance

### Layer Verification: ✅ PASS

**Layer:** Application (`crates/app/`)

**Allowed dependencies:**
- Shared layer ✅
- Infrastructure layer ✅
- Domain layer ✅

**Cargo.toml dependencies verified:**
- `systemprompt-models` (shared) ✅
- `systemprompt-traits` (shared) ✅
- `systemprompt-identifiers` (shared) ✅
- `systemprompt-provider-contracts` (shared) ✅
- `systemprompt-template-provider` (shared) ✅
- `systemprompt-extension` (shared) ✅
- `systemprompt-database` (infra) ✅
- `systemprompt-logging` (infra) ✅
- `systemprompt-config` (infra) ✅
- `systemprompt-cloud` (infra) ✅
- `systemprompt-content` (domain) ✅
- `systemprompt-files` (domain) ✅
- `systemprompt-templates` (domain) ✅

**No forbidden dependencies detected.**

### Structure: ✅ PASS

Application layer crates do NOT require repository/services structure (that's Domain layer only). Structure is appropriate for orchestration.

---

## Code Quality Metrics

### File Sizes: ✅ PASS

All 36 source files are under the 300-line limit.

| File | Lines | Status |
|------|-------|--------|
| `src/templates/html.rs` | 277 | ✅ |
| `src/prerender/content.rs` | 261 | ✅ |
| `src/templates/navigation.rs` | 251 | ✅ |
| `src/templates/paper.rs` | 245 | ✅ |
| `src/prerender/parent.rs` | 242 | ✅ |
| `src/sitemap/generator.rs` | 226 | ✅ |
| All others | <211 | ✅ |

### Function Sizes: ✅ PASS

No functions exceed the 75-line limit.

### Parameters: ✅ PASS

Functions use parameter structs appropriately (e.g., `RenderParentParams`, `TemplateDataParams`, `BuildTemplateJsonParams`).

## Commands Executed

```
SQLX_OFFLINE=true cargo clippy -p systemprompt-generator -- -D warnings  # PASS
cargo fmt -p systemprompt-generator -- --check                            # PASS
```

## Violations Fixed (This Review)

| File:Line | Violation | Fix Applied |
|-----------|-----------|-------------|
| `src/prerender/homepage.rs:16` | `unwrap_or_default()` silently swallows error | Changed to `?` for proper error propagation |
| `src/templates/navigation.rs:222` | `unwrap_or_default()` on Option | Changed to `map_or_else(String::new, \|...\|)` |
| `src/build/orchestrator.rs:60-61` | `#[allow(dead_code)]` on `mode` field | Added public `mode()` accessor method |
| `src/templates/navigation.rs:241` | Hardcoded copyright year and company | Extracted from `web_config.branding.copyright` |
| `crates/infra/cloud/src/api_client/types.rs:2` | Unused re-export `ApiErrorDetail` | Removed from re-exports |

## Verdict Criteria

| Verdict | Criteria |
|---------|----------|
| **CLEAN** | Zero critical violations, ready for crates.io |
| **NEEDS_WORK** | Minor issues, can publish with warnings |
| **CRITICAL** | Blocking issues, must resolve before publication |

**This crate is rated CLEAN:**
- ✅ Zero critical/zero-tolerance violations
- ✅ All code quality warnings resolved
- ✅ All tech debt items resolved
- ✅ Clippy passes with `-D warnings`
- ✅ Formatting passes

The crate is ready for crates.io publication.

## Positive Observations

- Clippy passes with `-D warnings`
- Proper use of `?` operator for error propagation
- Good use of iterator chains and combinators
- Jobs implement the `Job` trait interface correctly
- Orchestration pattern followed (coordinates domain services)
- Proper structured logging with `tracing`
- No `unwrap()` or `panic!()` usage
- No `unsafe` code
- No direct SQL in application layer
- No direct environment variable access
- All files under 300 lines
- No inline comments
- No TODO/FIXME comments
- Uses `inspect_err()` pattern for logging before `.ok()`
- Uses `const fn` where appropriate
- Copyright now configurable via `branding.copyright`
