+# Reddit SRE + Founder corpus (v2)
+
+1475 unique posts scraped from 15 subreddits between 2013-06-14 and 2026-06-19. Built for product discovery on the Kubernetes Incident Autopilot hypothesis — agents that reason at inference time through incident diagnosis, with humans in an override loop.
+
+## Subreddits (15)
+
+SRE tier: r/sre, r/devops, r/kubernetes, r/sysadmin, r/aws, r/azure, r/gcp, r/programming, r/ExperiencedDevs, r/chaosengineering
+
+Founder tier: r/Entrepreneur, r/startups, r/SaaS, r/IndieHackers, r/ycombinator
+
+## Sources
+
+Two scrape backends, both Pushshift-compatible JSON:
+- **PullPush** (api.pullpush.io) — original 792 posts
+- **Arctic Shift** (arctic-shift.photon-reddit.com) — recovered 683 previously-missing posts (the open successor to Pushshift, no auth required)
+
