ops scripts — experiment 6 #

Persisted out of a session scratchpad so they survive the run. See docs/experiment-6-handoff.md.

• check6.sh — the periodic check. Reports every rate with its discriminators attached (nested 1h/6h/12h windows, a measured delta against the previous run, a batch-trough warning) so a short-window artifact cannot be mistaken for a trend. State file defaults to ~/.stream-exp6; override with SC=.
• wsprobe.py — minimal websocket client. wsprobe <cursor> (runs on the box under system python3) against bsky.network; prints 101 plus a binary commit frame if the firehose will still replay from that cursor. This is how you check the replay window has not lapsed. Deployed to /usr/local/bin/wsprobe on the workload host.
• dash-snapshot — writes /srv/dash/data.json on the workload; driven by dash-snapshot.timer every 60s.
• dash-index.html — the dashboard page, installed at /srv/dash/index.html.

Tooling note: wsprobe.py and dash-snapshot run on the Hetzner hosts, where uv was never installed, so they use system python3. That is a provisioning gap, not a requirement — uv is a single static binary and installing it on the hosts would unify things. Do it at next provision rather than under a live run. Anything on the operator's own machine uses uv / uvx / jq, never python3.
