Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	User can crawl Zhihu answers with question title, description, answer content	VERIFIED	crawl_answer() returns AnswerData with all fields
2	User can crawl Zhihu articles with title and body	VERIFIED	crawl_article() returns ArticleData with all fields
3	User can optionally include comments when crawling	VERIFIED	include_comments parameter in crawl_answer()
4	Crawl results include author info, publish time, vote count	VERIFIED	ContentMetadata with AuthorInfo, timestamps, vote counts
5	User can configure proxy via environment variables	VERIFIED	CrawlerConfig.from_env() reads HTTP_PROXY/HTTPS_PROXY
6	Crawler rejects execution without proxy when proxy_required=True	VERIFIED	validate_proxy() raises ValueError when no proxy configured
7	Requests have random delay (1-3s) with retry on failure	VERIFIED	_apply_random_delay(), _crawl_with_retry() with tenacity

Score: 7/7 truths verified

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
-	-	No TODO/FIXME/placeholders found	-	-

No anti-patterns detected. All implementations are substantive with proper error handling.

Human Verification Required

1. Integration test with real Zhihu URL

   • Test: Run crawler against actual Zhihu URL with valid cookie and proxy
   • Expected: Crawl returns structured data with metadata
   • Why human: Requires real network access and valid cookie - cannot mock

2. Proxy configuration verification

   • Test: Configure proxy and run crawler against Zhihu
   • Expected: Crawler works correctly with configured proxy
   • Why human: Requires actual proxy server to verify network behavior

Summary

All 7 must-haves from the 3 plans (08-01, 08-02, 08-03) have been verified:

• CONT-01, CONT-02, CONT-04 (Plan 08-01): Answer/Article crawling with metadata - VERIFIED
• CONT-03 (Plan 08-02): Comment crawling with optional switch - VERIFIED
• NET-01, NET-02, NET-03 (Plan 08-03): Proxy, rate limiting, signature handling - VERIFIED

Test Coverage: 44 tests, all passing

Code Quality: No anti-patterns detected. Clean implementation with:

• Proper separation of concerns (models, config, crawler)
• Comprehensive error handling
• Retry with exponential backoff
• Fallback DOM parsing for articles
