5c882c3a46 fix: refresh stale price observations after 7 days + fix ATGBICS pagination wrap-around
- upsertPriceObservation: insert new observation if last one is >7 days old,
  even when price (content_hash) hasn't changed — keeps timeseries data fresh
- ATGBICS: detect Shopify catalog wrap-around by tracking per-category seen URLs;
  stop pagination when all products on a page were already seen in a prior page
- ATGBICS: improve hasNextPage to match &page=N anchored in href params

1da4abc488 fix: FS.com price extraction — DOM-based prices + shipping-context exclusion
- All 247 FS.com prices were €79 (shipping threshold, not product prices)
- Root cause: 'Gratis Versand ab 79 € (ohne MwSt.)' banner matched first
- Fix 1: DOM price extraction in page.evaluate with bad-parent skip list
- Fix 2: bodyText qualified patterns skip matches near shipping keywords
- Fix 3: waitForSelector for price DOM element before evaluate
- Fix 4: Deleted 247 invalid €79 observations from DB

Also included from previous session:
- db.ts: set has_image=true on image writes (fix 632 desync rows)
- spec-updater.ts: DR/FR/LR/ER/ZR → SMF, SR → MMF fiber type inference

5393f73c17 feat: stock quality schema + QSFPTEK/NADDOD v2 scrapers with real-time stock counts
- Migration 028 (retroactive): document warehouse columns added to stock_observations
- Migration 037: composite indexes for DISTINCT ON (transceiver_id, source_vendor_id) queries
- Migration 038: add stock_confidence (1/2/3), price_currency, price_includes_tax,
  stock_vendor_ts to stock_observations + TRUNCATE test-run data

db.ts: upsertStockObservation now accepts stockConfidence, priceCurrency,
priceIncludesTax, stockVendorTs; delta detection includes quantity_available

fs-com.ts: passes stockConfidence=3 + priceCurrency=EUR + priceIncludesTax=false

qsfptek.ts v2: Phase 1 API listing + Phase 2 detail-page stock extraction
- Parses 'X in real-time stock, DATE' from product detail pages
- Writes stock_observations with confidence=2 + stockVendorTs
- Up to 500 detail pages/run at 2s rate limit

naddod.ts v2: complete rewrite from WooCommerce to Astro sitemap-based
- Discovers products via /sitemaps/products.xml (600+ products)
- URL format: /products/XXXXX.html
- Extracts 'In Stock: X' exact counts from SSR HTML
- Writes both price + stock observations (confidence 1 or 2)

5b35b2b8be feat(scraper+api): warehouse stock data pipeline — FS.com v2, SmartOptics v2, Stock API
Scraper changes:
- fs-com.ts v2: Playwright stealth patches + www.fs.com/de/ URL fix (de.fs.com DNS NXDOMAIN).
  Extracts DE-Lager, Global-Lager, Nachlieferung, units_sold, compatible_brands, price_net.
  Mac-side runner (run-fs-scraper-mac.sh) via SSH tunnel for residential IP access.
  Fast-fail connectivity check on datacenter IPs that are blocked by Cloudflare.
- smartoptics.ts v2: WooCommerce REST API fallback + 8 catalog categories + relative URL fix.
  Was finding only 8 products, now discovers 18+ with multi-category crawl.

DB layer:
- db.ts: add upsertStockObservation() — writes 10 new stock_observations columns
  (warehouse_de_qty, warehouse_global_qty, backorder_qty, units_sold, compatible_brands,
  price_net, product_url, delivery dates) with dedup check.

API:
- routes/stock.ts: GET /api/stock, /api/stock/summary, /api/stock/:id
  Warehouse breakdowns per transceiver/vendor with top-sellers and vendor summary.
- routes/review.ts: equivalence review queue (approve/reject/bulk-approve).
- index.ts: register /api/stock and /api/review routes.

Dashboard:
- index.html: 🏭 Stock tab with stat cards (DE-Lager, Global-Lager, Nachlieferung totals),
  top-sellers table, vendor breakdown, recently-restocked events, part-number lookup.

SQL migrations:
- 034: blog-review-tag, 035: price-observations is_anomalous, 036: transceiver-equivalences.

cf75eee8ad feat: linecard system support, Cisco 8000 accuracy, price anomaly detection
API/finder:
- Add modular chassis support: sibling linecards fetched when is_linecard=true
- Add chassis linecards when system_type=modular
- Extend switch response: system_type, is_linecard, chassis_model, slot_type,
  flexbox_compat_mode, flexbox_notes, description, switching_capacity_tbps,
  total_ports, category, lifecycle_status, features, use_cases, linecards[]

API/transceivers:
- Filter price_observations with COALESCE(is_anomalous, false) = false
  (direct prices + comparable market prices)

Scraper/db:
- Add PRICE_BOUNDS map (per form-factor min/max USD sanity bounds)
- Add isPriceAnomalous() — marks DB price_observations as is_anomalous=true
- Add competitor_verified flag: set true when valid competitor price stored
- upsertPriceObservation: skip prices outside sanity bounds, set competitor_verified

Scraper/hash:
- contentHash() now accepts Record<string,unknown> | string (union type)
  to support both structured objects and legacy string callers

Scrapers (skylane, tscom, wiitek):
- Fix contentHash() call signature: pass objects not JSON.stringify strings
- Fix wiitek: remove invalid 'name' param, fix t.id → transceiverId

Migrations:
- Add is_anomalous, competitor_verified, competitor_verified_at,
  image_primary columns
- Recreate sync_fully_verified trigger to include competitor_verified
- Add is_linecard, chassis_model, system_type, slot_type,
  flexbox_compat_mode, flexbox_notes to switches table

f616e0ebbe feat: blog engine v4 (reduction+style-lock passes) + flexoptix scraper fixes
Blog engine (fo-blog-pipeline.ts):
- Add STEP8b_REDUCTION: cuts article 25-35%, removes repeated concepts
- Add STEP8c_STYLE_LOCK: enforces tone consistency, fixes scope/OPM confusion,
  removes inline SKUs from article flow
- Add Gold Standard 3 to calibration (Style B troubleshooting example 2026-04-04)
- Pipeline now 12 steps (was 10), version bumped to v4-reduction-stylelock

blog.ts:
- Wire STEP8b and STEP8c into pipeline between Kill-AI-Tone and QA Check
- Update progress tracking to 12 total steps
- Update pipeline_version to 'v4-reduction-stylelock'

flexoptix-catalog.ts:
- Fix contentHash call: pass object directly, not JSON.stringify(object)

db.ts:
- price_verified=true set in content_hash early-return path (no new observation)
- image_verified=true auto-set in findOrCreateScrapedTransceiver on INSERT/UPDATE

c179b236d7 fix: auto-set image_verified and price_verified in db utils
- findOrCreateScrapedTransceiver now sets image_verified=true when writing image_url
- upsertPriceObservation now sets price_verified=true on the transceiver after inserting price
- Both INSERT and UPDATE paths covered for image_verified sync
- Eliminates need for manual backfill after scraper runs

- Fix DB connection pool: max 5, idleTimeoutMillis 10s (was unlimited, caused >100 connections)
- Add proxy.ts utility for scraper proxy rotation
