ADR: Wave-2 traffic comes from manual SimilarWeb screenshots

Date: 2026-06-30 Status: Accepted

Context

Wave-2 of the report standardization is 7 dataless companies (dell, footlocker, jbl, michaelkors, thenorthface, torrid, autozone) that need full re-audits. The traffic module needs SimilarWeb, but the SimilarWeb API key was revoked (401) and the browser-scraper session was expired. This was the one hard blocker stopping Wave-2.

Decision

Use manually captured, logged-in SimilarWeb screenshots as the traffic source for Wave-2. The user captured all 7 companies (10 tabs each: overview, performance, technologies, competitors, traffic and engagement, marketing channels, geography, demographics, audience interests, subdomains) at PIP/docs/temp/similarweb-wave2/. Traffic data is extracted from these screenshots by vision rather than from the dead API.

Rationale

The data exists and is real (verified, logged-in, no paywall blur). Reading it from screenshots removes the only dependency that needed a paid or live key. With this, every Wave-2 module is keyless: Scout, Gemini-grounded, detect-search on the VPS, yfinance, and these screenshots.

Alternatives Considered

Option Why rejected
Rotate the SimilarWeb key and re-run the API path Costs a paid key; the screenshots already exist
Re-auth the browser scraper Same captured data, but the screenshots are already in hand
Leave Wave-2 blocked No longer necessary; the blocker is gone

Consequences

  • The pipeline's collect-traffic.py expects the SimilarWeb API, so Wave-2 needs a small vision-extraction step (screenshots to 03-traffic-data.json) instead of the API call.
  • Wave-2 is now fully runnable and keyless. The earlier ledger (spike-unify-audit/run/FINAL-REPORT.md) that listed SimilarWeb as the blocker is superseded by this.
  • Corrects memory feedback-wave2-blocker-similarweb-mcp (now marked resolved).
