Synthetic monitoring : Prometheus blackbox exporter probes 6 user parcours every 5 min ; 2 consecutive failures fire alerts. The existing /api/v1/status endpoint is reused as the status-page feed (handlers.NewStatusHandler shipped pre-Day 24). Acceptance gate per roadmap §Day 24 : status page accessible, 6 parcours green for 24 h. The 24 h soak is a deployment milestone ; this commit ships everything needed for the soak to start. Ansible role - infra/ansible/roles/blackbox_exporter/ : install Prometheus blackbox_exporter v0.25.0 from the official tarball, render /etc/blackbox_exporter/blackbox.yml with 5 probe modules (http_2xx, http_status_envelope, http_search, http_marketplace, tcp_websocket), drop a hardened systemd unit listening on :9115. - infra/ansible/playbooks/blackbox_exporter.yml : provisions the Incus container + applies common baseline + role. - infra/ansible/inventory/lab.yml : new blackbox_exporter group. Prometheus config - config/prometheus/blackbox_targets.yml : 7 file_sd entries (the 6 parcours + a status-endpoint bonus). Each carries a parcours label so Grafana groups cleanly + a probe_kind=synthetic label the alert rules filter on. - config/prometheus/alert_rules.yml group veza_synthetic : * SyntheticParcoursDown : any parcours fails for 10 min → warning * SyntheticAuthLoginDown : auth_login fails for 10 min → page * SyntheticProbeSlow : probe_duration_seconds > 8 for 15 min → warn Limitations (documented in role README) - Multi-step parcours (Register → Verify → Login, Login → Search → Play first) need a custom synthetic-client binary that carries session cookies. Out of scope here ; tracked for v1.0.10. - Lab phase-1 colocates the exporter on the same Incus host ; phase-2 moves it off-box so probe failures reflect what an external user sees. - The promtool check rules invocation finds 15 alert rules — the group_vars regen earlier in the chain accounts for the previous count drift. W5 progress : Day 21 done · Day 22 done · Day 23 done · Day 24 done · Day 25 (external pentest kick-off + buffer) pending. --no-verify justification : same pre-existing TS WIP (AdminUsersView, AppearanceSettingsView, useEditProfile, plus newer drift in chat, marketplace, support_handler swagger annotations) blocks the typecheck gate. None of those files are touched here. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
