RFD update: GSC read side already live (additive isolation) (#29)
Verified prod: GSC read endpoints shipped as additive-only isolation (Heroku v967 = 4ba61f1), deployed ~7h ago. /snapshots returns 2,952 rows, /aggregates works, marketing-bot probe WIRED, all 6 GSC trials
Verified prod: GSC read endpoints shipped as additive-only isolation (Heroku v967 = 4ba61f1), deployed ~7h ago. /snapshots returns 2,952 rows, /aggregates works, marketing-bot probe WIRED, all 6 GSC trials show wired on the dashboard. Earlier 404 was a transient mid-deploy read.
The read-side dilemma is moot — done cleanly, clean baseline preserved, no blast radius. Remaining open item: deploy the SEO treatments (year fix, JSON-LD A/B, etc. — still not on prod) when the test gate is green; now lower urgency since the read side that blocked everything is live.
