Large retailers like Newegg legitimately reuse manufacturer stock photos
across listings. Duplicate photo hash is not a scam signal for sellers
with 1000+ feedback — suppress the red flag for them.
- Parallel execution: search() and get_completed_sales() now run
concurrently via ThreadPoolExecutor — each gets its own Store/SQLite
connection for thread safety. First cold search time ~halved.
- Pagination: SearchFilters.pages (default 1) controls how many eBay
result pages are fetched. Both search and sold-comps support up to 3
parallel Playwright sessions per call (capped to avoid Xvfb overload).
UI: segmented 1/2/3/5 pages selector in filter sidebar with cost hint.
- True median: get_completed_sales() now averages the two middle values
for even-length price lists instead of always taking the lower bound.
- Fix suspicious_price false positive: aggregator now checks
signal_scores.get("price_vs_market") == 0 (pre-None-substitution)
so listings without market data are never flagged as suspicious.
- Fix title pollution: scraper strips eBay's hidden screen-reader span
("Opens in a new window or tab") from listing titles via regex.
Lazy-imports playwright/playwright_stealth inside _get() so pure
parsing functions are importable without the full browser stack.
- Tests: 48 pass on host (scraper tests now runnable without Docker),
new regression guards for all three bug fixes.
Scraper can't fetch seller profile age without following each listing's
seller link. Using 0 as sentinel caused every scraped seller to trigger
new_account and account_under_30_days red flags erroneously.
- Seller.account_age_days: int → Optional[int] (None = not yet fetched)
- Migration 003: recreate sellers table without NOT NULL constraint
- MetadataScorer: return None for unknown age → score_is_partial=True
- Aggregator: gate age flags on is not None
- Scraper: account_age_days=None instead of 0
