The hall counts its visitors: a digest, a nightly rollup, and the games it sends people to

gamehall/ops holds the traffic counter, the visitors digest and the
nightly rollup, installed by gamehall/deploy.sh; the gamehall-visitors
skill reads them. The hall now sends its origin as referrer, so a game
can tell who came from it.

+name: gamehall-visitors
+description: Who is visiting Kestrel's Hall, the landing page at gamehall.kestrelsnest.social - the last hour, today, where they came from, how many went on into each game, and the week's trend. Use when Eric asks about hall traffic or visitors.
+---
+
+# Kestrel's Hall visitors
+
+One command on the shared host prints the digest:
+
+    ssh root@159.203.115.252 /usr/local/bin/gamehall-visitors.sh [YYYY-MM-DD]
+
+Default is today, UTC. It reads Caddy's access log for the hall's own
+name (the sslip test address is left out) and prints:
+
+- **last hour** (today only): people and page views, the "right now".
+- **today**: people (distinct addresses), page views, bot addresses.
+- **referrers** and **campaigns**: the sites that sent people, and the
+  tags links carry (`?ref=`, utm_source, Facebook's fbclid). Reddit and
+  some apps send no referrer.
+- **went on to**: people each game on this host (Dip, Waving Hands,
+  Hnefatafl) received with the hall as referrer. The hall sends its
+  origin as referrer, nothing more. Wiz-War is on its own droplet; its
+  own digest (/wizwar-visitors) lists gamehall.kestrelsnest.social among
+  its referrers.
+- **last 7 days** from `/var/lib/gamehall/rollup.jsonl`, written nightly
+  at 00:05 UTC by `gamehall-rollup.sh` for the day before (counts only,
+  no addresses).
+
+## Read it
+
+Lead with whether anyone is here now and today's people, then where they
+came from, then how many went on into a game (the hall's job is to send
+people to tables). Give the week's direction from the rollup in one
+sentence. Eric's own devices count as people; a handful on a quiet day
+may be him.
+
+The source is `gamehall/ops/` in game-kit; `gamehall/deploy.sh` installs
+it on every publish.
