 *Part of `docs/roadmap/` — see [`intro.md`](intro.md) for platform/background context and [`summary.md`](summary.md) for how every phase fits together. Prev: [`phase-5.md`](phase-5.md) · Next: [`phase-7.md`](phase-7.md)*
 
-**Status:** Not started
+**Status:** Done
 
-**Message:** Depends on Phases 3–5 producing traces, logs and metrics worth
-dashboarding.
+**Message:** Done 2026-10-25. Both Done-when criteria verified live: Grafana's
+resources and its volume were deleted and `kubectl apply -k k8s/` rebuilt all
+six dashboards and four datasources from the files (fresh PVC, every dashboard
+`provisioned: true`), and every dashboard's version history shows only the
+provisioner as author.
+
+- **Build steps done:** 1, 2, 3, 4 (`tracesToMetrics` added; the
+  `tracesToLogsV2` question was not answered) and 5.
+- **Dashboards:** `observability/dashboards/generate.py` (Foundation SDK)
+  writes `k8s/grafana/dashboards/*.json`: `red-<service>` for the five HTTP
+  services (gateway, ledger, fraud, sanctions, insights; audit and notifier
+  serve no HTTP, so have none) and `overview` (service graph, stream lag, pool
+  in use). No error-budget panel yet (Phase 8). The app exports no pool *size*,
+  so the pool panel shows "in use", not saturation. The generator refuses to
+  write while a `FIXME` remains and checks the total size against the
+  ConfigMap limit.
+- **Alerts:** Prometheus rule files, not Grafana alerting, delivering to
+  Alertmanager (`default` receiver is still a no-op). `LedgerlineTargetDown`
+  and `LedgerlineHighErrorRatio` in `k8s/prometheus/rules/ledgerline.rules.yml`,
+  under an alerting contract (labels `severity`/`team`/`service`; annotations
+  `summary`/`description`/`runbook_url`/`dashboard`) enforced by
+  `observability/alerts/check_contract.py`, with runbooks in `docs/runbooks/`.
+  A scratch alert was seen in Alertmanager; `LedgerlineHighErrorRatio` was seen
+  `pending` on real traffic, but its firing and rendered annotations were not
+  verified. The runbook URLs are a guessed Gitea-style path and returned 404
+  before the files were pushed.
+- **Not done:** answering the `tracesToLogsV2` / `filterByTraceID` question
+  (the `QUESTION` comment is still in `k8s/grafana/datasources.yml`); clicking
+  "Related metrics" on a span to confirm `tracesToMetrics` end to end; a real
+  firing of either `ledgerline` alert; Grafana-managed alerting (Phase 8
+  decides).
+- **Carry forward:**
+  - The SDK's PyPI versions are `<epoch>!<grafana-version>`, and pip's default
+    picks the *oldest* schema (10.1). Pin `grafana-foundation-sdk==1769699379!11.6.0`
+    (newest published is the 11.6 schema; Grafana 12.1.1 loads it).
+  - Provisioned dashboards can't be deleted from the UI or API in Grafana
+    12.1.1 whatever `disableDeletion` says (the error is "provisioned dashboard
+    cannot be deleted"). Removing the *file* removes the dashboard. The destroy
+    test is `kubectl kustomize k8s/grafana | ssh falken kubectl delete -n
+    ledgerline-observability -f -` then re-apply. **Do not run `kubectl delete
+    -k k8s/`**: the root kustomization includes the Prometheus, Loki and Tempo
+    PVCs and would delete all telemetry.
+  - The configMap hash suffix rolls the pod on every change and leaves old
+    hashed ConfigMaps behind (plain `apply` doesn't prune them).
+  - Tempo's service map is built in the browser from Prometheus queries; the
+    `serviceMap` query type returns "unsupported query type" through
+    `/api/ds/query`, so that panel can only be checked by eye.
+  - An unlabelled series renders as "Value" in a legend. The gateway's 404s have
+    no `http_route`, so the rate panel shows one.
+  - `team` on an alert is static per rule (who answers the class of alert), not
+    per service. Phase 8's burn-rate rules belong in `k8s/prometheus/rules/`
+    under the same contract.
 
 **Time-box:** 2 evenings. This is an explicit requirement from Babak: *destroy and
 recreate in seconds.*

+# LedgerlineHighErrorRatio
+
+**Fires when:** a service's 5xx ratio is above 5% for 5 minutes, with more than
+0.05 requests/s (so it is not one failed request on an idle service).
+**Severity:** warning · **Team:** payments
+
+## What it means
+
+A meaningful share of the requests this service serves are failing with a server
+error. 4xx responses (for example a 404) are deliberately not counted.
+
+## First five minutes
+
+1. **Look at the `RED: <service>` dashboard** (linked in the alert). Is the error
+   ratio still elevated, or already back to normal? Did the request rate or the
+   latency change at the same time?
+2. **Find a failing request.** In Tempo, search for the service with an error
+   status, or in Loki: `{service_name="<service>"} | json | level="ERROR"`.
+3. **Follow one trace.** The `trace_id` in the log line opens the whole request
+   across services. Look for the first span in the trace with an error status.
+4. **Is it only this service?** The System overview's service graph shows whether
+   its callers or callees are failing as well.
+
+## Escalate when
+
+The ratio is still rising after ten minutes, or the failing requests are on the
+critical path (transactions), not a side route.

+# LedgerlineTargetDown
+
+**Fires when:** Prometheus has failed to scrape a Ledgerline service for 2 minutes.
+**Severity:** critical · **Team:** platform
+
+## What it means
+
+Prometheus scrapes all seven services through one address,
+`https://ledgerline.vione.cloud/metrics/<service>` (czy's Traefik, basic auth).
+"Down" means that scrape failed. It does **not** by itself prove the service is
+down: the service, the proxy, or the credentials can each cause it.
+
+## First five minutes
+
+1. **How many targets?** Open the alert in Alertmanager. One service alerting is
+   likely that service. All seven at once points at the shared path (Traefik on
+   czy, DNS, the scrape credentials), not at the services.
+2. **Ask Prometheus why.** In Prometheus → Status → Targets, find the target and
+   read its `Last error`.
+3. **Is the container running?** `ssh czy docker compose ps` for the service.
+4. **What did it last say?** `ssh czy docker logs ledgerline-<service>-1`, or in
+   Loki: `{service_name="<service>"}`.
+5. **Is traffic still flowing?** Open the `RED: <service>` dashboard. Traces and
+   logs can still be arriving while only the metrics scrape is broken.
+
+## Escalate when
+
+The shared path is down (all seven targets), or the service is down and not
+recovering after a restart.
