GRIND GURUS — LINK CHECKER VERIFICATION RECEIPT Recorded October 10, 2026 Scope Operator-published summary of the link-checker build shipped in private repository PlanPost-Studio/grindgurus, PR #52. Merged commit: 036cf9f63b62bc3e2a961dfb7bc57d706bd7486d Source code, GitHub review discussion, and Actions logs are private. This summary is not independent certification or a public source release. No credentials, customer data, or internal environment configuration is included. Final regression checks for that build npm run test:links: 5 tests passed; 0 failed. npm run test:cloudfront: 17 assertions passed. npm run build: passed. npm run check:links -- --offline: 127 OK; 0 errors; 9 built HTML pages. git diff --check: passed. The clean-site fixture requires CLI exit 0 for valid extensionless routes, anchors, assets, and generated redirects. The broken fixture requires exit 1. A synthetic HTTP 200 page titled "Channel Not Found" must fail classification. These are controlled regression fixtures, not a claim that every external service is usable. Live audit snapshot 153 OK; 0 ERROR; 6 BROWSER; 0 UNVERIFIED. All 15 live /go redirect hops matched the canonical destination configuration. Amazon, Bluesky, Instagram, Spotify, TikTok, and Twitch remained browser-required. Their destination content was NOT counted as verified. These audit totals were recorded before the review follow-up; the follow-up changed local route normalization and success-path fixtures, not destinations. Review corrections - Mirror the preview router's extensionless route rules. - Require a clean-site fixture and actual CLI exit 0, alongside broken-site exit 1. Final preview CI passed on Node 24 after those corrections. Production workflow 38092309015 (Deploy to S3) concluded success for the merged commit listed above. Limits and next verification The offline deployment gate does not request external destinations. A successful exit code is not proof that browser-required destinations work. Title/heading heuristics can miss failures or misclassify error documentation. A JavaScript shell, challenge, or bot wall needs direct browser follow-up. Counts describe this dated build, not ongoing availability. No measured traffic, revenue, or time-saving outcome is claimed.
