price?: number narrowing via typeof/!== undefined does not work for
arithmetic comparisons in TypeScript 5.9 dead code paths; use 'as number'
cast to keep the dead code compilable while the early-return guard above
prevents runtime execution entirely.
- ATGBics: update HTML parser from old card--product theme to new
card__info theme (Shopify template changed April 2026); name now
extracted from href link text instead of aria-label
- NADDOD: correct ensureVendor shop URL from /collections/transceivers
(404) to /collection/optical-transceivers
- VCELink: disable scraper — site pivoted from optical transceivers to
audio/video/cable products; all collection URLs return 404
- Replaces Playwright with pure fetch() — static HTML has prices
- Correct collection handles (compatible-transceivers-sfpp-10g etc.)
- Cookie: cart_currency=GBP forces GBP pricing from any geo-IP
- Handles 35+ pages per category × 24 products = 840+ SFP+ products
- No IP-blocking with static HTML (Playwright was the trigger)
- Adds scripts/run-atgbics-mac.sh for Mac-side runner if needed
- 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
10gtek.com main site only exposes technical spec tables with no prices.
sfpcables.com is 10Gtek's own retail store and has both Model numbers
and USD prices in standard Magento product listings.
Changes:
- Switch scraping target from www.10gtek.com to sfpcables.com
- Parse Model: <part> + US.XX per product block (Magento structure)
- XFP fallback: extract part number from title after '|' separator
- Add fetchAllPages() with Magento loop-detection via seen-part dedup
- Remove QSFP-DD category (not available on sfpcables.com)
- Drop XFP-less categories from old 10gtek.com spec-table parser
Verified: 10/10 SFP prices, 10/10 SFP+ prices, 4/4 XFP prices on live site.
Pattern 1 (href→aria-label) finds 127 navigation links on GBICS BigCommerce
pages — none contain GBP prices. Pattern 2 (aria-label→href) correctly
finds 16-30 product links per category page with £XX.XX prices in aria-labels.
The fallback from P1 to P2 now triggers when P1 finds results but none
contain '£', rather than only when P1 finds 0 total results.
After PlaywrightCrawler.run() resolves, Crawlee's internal task loop
schedules one final _isTaskReadyFunction call that tries to read a
request queue .json file already cleaned up during processing. This
ENOENT fires as an unhandledRejection and calls process.exit(1),
aborting Phase 2 before prices are written to the database.
Added a targeted unhandledRejection handler in the require.main block
that swallows ENOENT errors from request_queues paths (benign Crawlee
cleanup race) while re-raising all other rejections.
- Add makeCrawleeConfig isolation to CheerioCrawler instances
- Switch from named persistent RequestQueue to ephemeral null queues:
named queues retain 'handled' state and skip all URLs on re-runs,
causing 0 observations on every run after the first.
- Applies to both enrichSwitchFromEbay and enrichTransceiversFromEbay.
- Add utils/crawlee-config.ts: makeCrawleeConfig(name) returns a
Crawlee Configuration with isolated localDataDirectory per scraper.
Uses storageClientOptions (not global CRAWLEE_STORAGE_DIR) so
concurrent pg-boss workers in the same process don't race on
the shared env var.
- Apply makeCrawleeConfig to all 6 Crawlee-based scrapers:
optcore (PlaywrightCrawler), atgbics (PlaywrightCrawler),
community-issues (CheerioCrawler + RequestQueue),
edgecore (CheerioCrawler), ufispace (CheerioCrawler),
market-intelligence (CheerioCrawler).
- scheduler.ts: add withIsolatedStorage for optcore and market-intel
workers (was missing, caused storage-fs path bleed from fs scraper).
- ebay-enricher.ts: fix vendor type 'marketplace' -> 'reseller' to
satisfy vendors_type_check constraint
['manufacturer','distributor','oem','reseller','compatible'].
FiberMall:
- Correct /store-XXXXX-name.htm category URLs (was /c/xxx/ → HTTP 404)
- Parser: split on new_proList_mainListLi, price from data-price on
currency_price span — fix 0.00 false-match from SKU variant items
- Also scrape SKU brand variant links from .sku_item divs
- Result: 3,410 prices now in DB (was 0)
Flexoptix:
- Fix extractPrice regex for EUR thousand-separator format
(2,921.60 EUR was parsed as 2 EUR)
- Add OSFP224 / 1.6T search queries (4 new, form factor was missing)
- Fix O.138HG2.C.05 stale price 3009.60→2921.60 EUR
Schema: competitor_verified + competitor_verified_at columns
added via ALTER TABLE (were referenced in code but missing in DB)
CHANGELOG: added 6 entries for 2026-04-12
- New scrapers: fibermall.ts (WooCommerce), vcelink.ts (Shopify), opticsbay.ts (WooCommerce)
- QSFPTEK rewritten to use /mall/commodity/list API (old OpenCart /c/*.html paths gone 404)
- New: attribute-based filtering by data rate (1G/10G/25G/40G/100G/200G/400G/800G)
- Scrapes HTML fragments, extracts US$ prices and product URLs
- scheduler.ts: +3 queues/schedules/workers (fibermall, vcelink, opticsbay) → 61 total workers
- index-pi.ts: Pi fleet picks up all 3 new scrapers
ProLabs uses B2B quote model - prices require reseller account and are
not shown publicly (schema.org always shows price=0.00). Fighting
CloudFront WAF with Firefox automation is pointless.
New approach:
- Sitemap-driven: downloads all 14 sitemaps to collect product URLs
- fetch-based: curl-compatible HTTP requests bypass CloudFront TLS detection
- catalog-only: writes part numbers + specs to transceivers table
- Rate-limited: 300ms between requests (~3 req/sec)
- No proxy needed: Pi nodes no longer consumed for ProLabs
Routes requests through CT130/131/132 proxy pool (192.168.178.77/76/74:1080)
when PROXY_URLS env var is set. Uses ProxyConfiguration from crawlee for
PlaywrightCrawler scrapers and socks-proxy-agent for fetch-based scrapers.
EUR prices scraped verbatim from de.fs.com — no conversion needed.
USD derivation (EUR→USD) happens downstream, not EUR←USD.
Fixes price discrepancy: TIP showed USD 999×0.92=EUR 866 vs real €948 on de.fs.com.
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
Add Comms-Express, Router-Switch.com, Multimode Inc, OpticTransceiver.com,

XENPAK, CSFP, SFP-DD, SFP56, QSFP56 and other previously-uncovered form
factors. Each scheduled every 8h. Worker registrations added to scheduler.
Also export db alias in utils/db.ts to fix eBay enricher + community scrapers
crashing with 'Cannot read properties of undefined (reading query)'.
