Phase 4 records what was built, the two skipped Build steps (OTLP-logs
experiment, LogQL test migration) and what carries forward. Phase 3
records its outcome, with the chaos-nightmare and blocking_event_loop
criteria attested by the user.

Alloy only registers an OTLP/HTTP route for a signal with an output, so
POST /v1/metrics and /v1/logs return 404 rather than being accepted and
silently dropped (verified live against otlp.vione.cloud). Fix the claim
everywhere it appeared. Also mark Phase 2 in progress.

k8s/ is now a faithful port of the mentor's Ansible Grafana stack
(Prometheus, Alertmanager, Loki, Tempo, Alloy, Grafana, node-exporter)
for the ledgerline-observability namespace on falken: same versions and
configs, one *.vione.cloud ingress per tool behind Traefik basic auth,
secrets generated by create-secrets.sh into gitignored files.
Two fixes over the Ansible role, both verified live: Tempo's
metrics-generator needs traces_storage or it runs no processors, and
Prometheus needs exemplar-storage to keep exemplars.
Ledgerline stays on czy; an Alloy agent in the Traefik override ships
its container logs to Loki. Roadmap and CLAUDE.md now point at k8s/.

Insert a new Phase 1 (deployment: Compose + Traefik on a server, marked
Done) between the base project and the OTel concepts phase, and shift
the old phases 1-10 to 2-11. Update summary, intro, README and CLAUDE.md
references (spoiler rules now target Phase 9, the bottleneck hunt).
Add docker-compose.traefik.yml: an override that fronts the gateway with
Traefik and Let's Encrypt and removes all other published host ports.

Roadmap, phase specs, pathology catalog, and CLAUDE.md establishing
Ledgerline as an observability learning project built on a deliberately
imperfect seven-service payments backend.
