Bugbot caught a High-severity miss in v1.2.0's release-scoping work (PR #72). The OpenShift SCC template was the one resource-monitor file not updated when the literal `tracebloc-resource-monitor` ServiceAccount name moved to `<Release.Name>-resource-monitor`. On OpenShift the SCC granted access to a SA name that no longer existed, so the resource- monitor DaemonSet pods would fail to launch (no SCC -> can't mount hostPath /proc and /sys for node metrics). The SCC's metadata.name + ClusterRole.name + ClusterRoleBinding.name were ALREADY release-scoped (`tracebloc-resource-monitor-<release>` / `tracebloc-resource-monitor-scc-<release>`), so this slipped through — casual reading suggested it was already done. Touchpoints in resource-monitor-scc.yaml: - users[0]: now {{ include "tracebloc.resourceMonitorName" . }} - ClusterRoleBinding subjects[0].name: same helper - All `app: tracebloc-resource-monitor` labels: same helper, for consistency with the rest of the chart's resource-monitor templates - Updated the kubernetes.io/description SCC annotation prose so the literal name doesn't appear there either (cosmetic, but easier to audit "no literal references" with a single grep). Tests: - platform_test.yaml gains 3 new cases: SCC users[0] points at release-scoped SA, ClusterRoleBinding subject does too, and two releases (stg + cisco/hasan-prod) produce non-colliding SA references. - node_agents_namespace_test.yaml had a regression assertion checking the OLD literal name in users[0]; updated to the new release-scoped form (`RELEASE-NAME-resource-monitor`, helm-unittest's default release name when none is set). - 98 -> 102 passing. Verified end-to-end with two side-by-side `helm template` runs: - stg -> users[0] = system:serviceaccount:tracebloc-node-agents:stg-resource-monitor - hasan-prod -> users[0] = system:serviceaccount:tracebloc-node-agents:hasan-prod-resource-monitor Chart bumped 1.2.1 -> 1.2.2 (patch — restores OpenShift parity that v1.2.0 inadvertently broke).

Bugbot follow-up to the v1.2.0/1.2.2 rename work. Two fresh issues: 1. (Medium) NOTES.txt:9 still hardcoded the literal `tracebloc-resource-monitor` for the resource-monitor DaemonSet display, while the actual DaemonSet name has been `<release>-resource-monitor` since v1.2.0. Operators see one name in the post-install banner and a different name when they `kubectl get ds`. Now routes through the same tracebloc.resourceMonitorName helper as the rest of the chart. 2. (Low) docs/migration-tools/generate.sh hardcoded `app.kubernetes.io/version: "1.1.0"` and `helm.sh/chart: client-1.1.0` on every pre-create PVC. The chart has moved through 1.1.0 → 1.2.3, and operators running generate.sh today get PVC labels stuck at 1.1.0 even though the install ahead is 1.2.3. Helm adoption itself is unaffected (it keys on meta.helm.sh/release-name, not the chart label), but the labels lie until a subsequent upgrade reconciles them, and `kubectl get pvc -L helm.sh/chart` is misleading during migration debugging. Fixed by reading name + version from client/Chart.yaml at generate time. Plus a few stale prose references caught while auditing the same path (no functional impact, but the doc was directing operators at "client fix in 1.2.0" as if it were still pending): - generate.sh inline comment on `resourceMonitor: false` rephrased from "until client-1.2.0 is published" to "until you have verified the chart you're installing is 1.2.0+" - migrate-tenant.sh banner relabelled from "v1.1.0 spec sanity" to "mysql spec sanity (v1.1.0+ shape: ...)" - README.md skip table cell on `resourceMonitor: false` rewritten to reflect that 1.2.0+ has shipped — operators on >=1.2.0 can flip it to true without colliding with the stg release Tests: 102 → 105 passing. New `client/tests/notes_test.yaml` covers: - Release-scoped resource-monitor name appears in NOTES.txt - A different release renders a different name (proves the helper isn't accidentally hardcoded) - Negative regex guards against the literal `tracebloc-resource-monitor` reappearing followed by a non-suffix character (i.e. the bare pre-1.2.3 form, while still letting the SCC line `tracebloc- resource-monitor-<release>` further down the file pass) - `resourceMonitor: false` removes the line entirely End-to-end smoke of generate.sh confirms PVCs ship with the live chart version (`helm.sh/chart: client-1.2.3` after this commit, verified against /tmp/tracebloc-migration-<demo>/pvcs.yaml). Stacked on PR #78 (v1.2.2 SCC fix), so this branch already contains the SCC SA-ref rename. Once #78 lands the diff against develop will reduce to just this commit. Chart bumped 1.2.2 → 1.2.3 (patch — operator-facing string fix + tooling correctness). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* Merge pull request #71 from tracebloc/docs/migrations-correct-option-b docs(migrations): correct Option B + add hasan-prod case + active-jobs pre-flight * chore: add default CODEOWNERS for auto-reviewer assignment (#73) * ci: add kanban closure-routing caller workflow (#75) * fix(client): release-scope resource-monitor names so multiple releases coexist (v1.2.0) (#72) Two client releases on the same cluster could not both deploy the resource-monitor DaemonSet because several resources templated into the shared tracebloc-node-agents namespace used the literal name `tracebloc-resource-monitor` rather than a release-scoped name. The second `helm install` failed with: Error: ServiceAccount "tracebloc-resource-monitor" in namespace "tracebloc-node-agents" exists and cannot be imported into the current release: invalid ownership metadata; ... must equal "hasan-prod": current value is "stg". Surfaced during the 2026-04-27 hasan-prod migration on tracebloc-templates-prod; worked around at the time by setting resourceMonitor: false on the second release, which means prod customers currently lose their per-CLIENT_ID metric stream until this lands. What changed: - New helper `tracebloc.resourceMonitorName` -> `<Release.Name>-resource-monitor`, centralised in _helpers.tpl alongside the existing per-release name helpers (secretName, serviceAccountName, etc.). - DaemonSet metadata.name, spec.selector.matchLabels.app, pod label app=, and spec.template.spec.serviceAccountName all now go through the helper. The selector + pod label have to move together because DaemonSet selectors are namespace-scoped: two DaemonSets in tracebloc-node-agents both selecting `app: tracebloc-resource-monitor` would each grab the other's pods, which is worse than the surface bug. - ServiceAccount metadata.name (resource-monitor-rbac.yaml) goes through the helper. ClusterRole / ClusterRoleBinding / Role / RoleBinding metadata.name were already release-scoped (`tracebloc-resource-monitor-<release>`) and stay as-is to avoid an unnecessary ClusterRole rename for upgrading installs. Only the *subject* names in (Cluster)RoleBinding change to point at the new SA. - Mirrored secrets (CLIENT_ID + dockerconfigjson) in tracebloc-node-agents: the secret names were already release-scoped via tracebloc.secretName / tracebloc.registrySecretName so they did not collide. Their `app` label was the literal value, which is harmless on uniquely-named resources but inconsistent — updated for consistency. - Chart bumped 1.1.0 -> 1.2.0. Per-release naming of cluster-singleton resources is a behaviour change for existing installs (DaemonSet name, ServiceAccount name, and selector label all change), so a minor bump signals that operators should review. Tests: 93 -> 98. New cases cover: - DaemonSet name + selector + serviceAccountName all release-scoped - ServiceAccount name release-scoped - ClusterRoleBinding subject points at the release-scoped SA - A second `helm template` with a different release name produces non-colliding names Verified end-to-end via `helm template stg ./client` and `helm template hasan-prod ./client` on the same chart: ServiceAccount, DaemonSet, and ClusterRoleBinding subject names all diverge per release. Upgrade path from 1.1.0: The DaemonSet and ServiceAccount rename triggers a Helm three-way merge that DELETEs the old `tracebloc-resource-monitor` resource and CREATEs the new release-scoped one. ~30-60s gap on each node where resource metrics are not collected. DaemonSet selector is immutable, so the delete-then-create path is what we want — helm upgrade handles this automatically because the names diverge in the stored manifest. No manual orphan cleanup needed. Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> * fix(client): allow training pods to reach mysql-client (v1.2.1) (#76) The training-egress NetworkPolicy added in v1.1.0 only permitted DNS and external TCP/443. Training pods load their dataset from the in-namespace mysql-client over TCP/3306 (core/utils/database.py::load_dataframe_from_sql_table), so under any CNI that actually enforces NetworkPolicy the connect failed with errno 111 and the Job CrashLoopBackOff'd before the first batch: Database connection failed: 2003 (HY000): Can't connect to MySQL server on 'mysql-client:3306' (111) RuntimeError: Database connection is not available for load_dataframe_from_sql_table Surfaced on a fresh client install (k3d / k3s, which enforces policy via the built-in kube-router) where jobs-manager could reach mysql but every training Job spawned with tracebloc.io/workload=training could not. Add a third egress rule scoped to podSelector {app: mysql-client} on TCP/3306. Same-namespace by default (no namespaceSelector), so it stays tight to the chart's own mysql pod and does not open the namespace generally. The egress[1] /32 ipBlock comment is updated to note that MySQL is now explicitly re-permitted by egress[2]. Verified on a k3d cluster: pre-fix nc to mysql-client:3306 from a pod with the training label was refused; post-fix it connects. * docs(migration-tools): tenant migration runbook for eks-1.0.x → client-1.x (#74) * docs(migration-tools): tenant migration runbook for eks-1.0.x -> client-1.x Captures the operational tooling validated during the 2026-04-27 stg and hasan-prod migrations and generalises it for the remaining tenants (bmw, cisco, charite) and any future tenant on the legacy chart family. What's here: - README.md walks the workflow + recommended ordering for the pending set + skip rationale for chart toggles (resourceMonitor: false, priorityClass.create: false, etc). - generate.sh consumes a tenant-config.env (gitignored) and emits, per tenant, /tmp/tracebloc-migration-<tenant>/{values,storageclass,pvcs}.yaml. Refuses to expand placeholder __FOO__ rows so an operator running generate.sh against the unmodified template fails fast. - migrate-tenant.sh is the parameterised runbook. `phase1` is non-destructive (mysqldump-then-chunked-cp, AWS Backup on-demand recovery point, dry-run render). `phase2` is one-shot per tenant (helm uninstall, claimRef clear, SC re-create, PVC pre-create with release-scoped Helm ownership stamp, helm install, verify mysql data + keep annotation in stored manifest). - tenant-config.example.env is the template; populated copy is the secret-bearing artifact and must stay local. No real secrets in any committed file: - DOCKER_PASSWORD placeholder (__DOCKER_HUB_PERSONAL_ACCESS_TOKEN__) - per-tenant CLIENT_ID / CLIENT_PASSWORD placeholders - MYSQL_ROOT_PW placeholder (it's image-baked; required from env at runtime, no committed default) - .gitignore now excludes docs/migration-tools/tenant-config.env (only the .example variant is tracked) Operational notes: - Every kubectl/helm call passes --context explicitly. The 2026-04-27 prod run hit a context-drift bug mid-migration; the explicit form is a hard requirement. - values.yaml ships with resourceMonitor: false. Flip true after the release-scoped resource-monitor names land in client-1.2.0 (separate PR). Until then the shared SA in tracebloc-node-agents collides with the stg release. - Phase 1 is idempotent and re-runnable. Phase 2 is destructive and one-shot per tenant. Operators should pause and eyeball Phase 1 outputs before running Phase 2 — that's deliberately not automated. Once all four pending tenants are on client-1.x, this directory is historical. client-1.x -> client-1.y upgrades follow plain `helm upgrade` because the new chart already templates `helm.sh/resource-policy: keep` on PVCs, so the migration protocol isn't needed for routine upgrades. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(migration-tools): address bugbot review feedback on PR #74 Three issues flagged by Cursor Bugbot on the migration scripts: * migrate-tenant.sh used macOS-only `md5 -q` and `stat -f%z` for chunked-cp verification (HIGH). Linux operators would abort Phase 1 mid-transfer. Add portable `_md5` and `_size` helpers that pick md5sum on Linux, fall back to md5(1) on macOS, and use `wc -c` instead of stat for size. * generate.sh placeholder gate inspected only CLIENT_ID + CLIENT_PASSWORD + PV_MYSQL, missing PV_LOGS, PV_DATA, SC_NAME, and DOCKER_PASSWORD (MEDIUM). Literal `__FOO__` placeholders silently rendered into values.yaml/pvcs.yaml and only blew up at kubectl apply / helm install time. Iterate over every per-row field, plus a one-shot global check for DOCKER_PASSWORD before the loop. Error messages now name the offending field. * Phase 2.5 readiness loop was an unbounded `while :; do … sleep 5; done` (MEDIUM). After the destructive helm uninstall, a non-converging install (image-pull error, mysql kill-loop recurrence, missing PVC binding) hung the script forever instead of surfacing the failure. Add a wall-clock deadline — default 600s, override via READY_TIMEOUT — and exit 1 with the last-seen pod state on timeout. * fix(migration-tools): address bugbot follow-up on PR #74 Two more issues raised on the previous fix commit: * Readiness wait loop aborted on empty pod list (HIGH). With `set -euo pipefail`, the routine post-install window where no pods are visible yet caused `grep -c .` to exit 1, killing the script on the very first iteration before the wall-clock deadline could ever fire — defeating the bounded-wait intent. Guard the empty case explicitly. `wc -l` alone is also wrong because `echo ""` prints a newline. * MYSQL_ROOT_PW skipped the placeholder check that DOCKER_PASSWORD, CLIENT_*, and PV_* now have (LOW). An operator who copied the example without editing this row passed the non-empty gate, then the literal __LEGACY_MYSQL_ROOT_PW__ went into mysqldump and Phase 1 blew up partway through with an opaque "Access denied" inside kubectl exec. Add the same `*__*__*` case guard right after the non-empty check. * fix(migration-tools): make EFS_FS_OVERRIDE actually override (PR #74) The pre-source assignment EFS_FS="${EFS_FS_OVERRIDE:-fs-06b3faf51675ff9f9}" was a no-op: `source "$CONFIG"` runs immediately after and the example config (and any real tenant-config.env derived from it) unconditionally sets EFS_FS=fs-06b3faf51675ff9f9, so the env override was clobbered every time. Operators thinking they were targeting a non-default EFS would silently start AWS Backup on-demand jobs against the hard-coded prod filesystem. Move the override knob to AFTER source where env genuinely wins, drop the hard-coded fallback, and require EFS_FS to be set somewhere (config or override) before continuing. --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> * fix(client): release-scope SCC SA refs (v1.2.2) (#78) Bugbot caught a High-severity miss in v1.2.0's release-scoping work (PR #72).

Summary
Second round of bugbot findings on the develop → main promotion (#77). Two real issues + three stale prose references caught in the same audit.
Stacked on #78 (v1.2.2 SCC fix). Once #78 lands the diff against develop reduces to just this commit. If you'd rather review them separately, I can rebase against develop after #78 merges.
Issues fixed
1. (Medium)
NOTES.txt:9showed wrong DaemonSet name post-installPre-fix output operators saw after `helm install`:
```
```
Actual DS name has been `-resource-monitor` since v1.2.0. The NOTES.txt template was missed in the rename.
Now routes through the same `tracebloc.resourceMonitorName` helper as the rest of the chart.
2. (Low)
generate.shhardcoded chart version1.1.0`docs/migration-tools/generate.sh` was written when the chart was 1.1.0 and stamped `app.kubernetes.io/version: "1.1.0"` + `helm.sh/chart: client-1.1.0` on every pre-create PVC. Chart has since moved through 1.2.0/1.2.1/1.2.2/1.2.3.
Helm adoption itself is unaffected (it keys on `meta.helm.sh/release-name`), but the labels lie until a subsequent upgrade reconciles them, and `kubectl get pvc -L helm.sh/chart` becomes misleading during migration debugging. Fixed by reading name + version from `client/Chart.yaml` at generate time.
Stale prose references (caught while auditing — no functional impact)
What I ruled out (audit notes)
I went looking for additional stale references in the same vein and intentionally did not change:

Note
Medium Risk
Operationally impactful because it changes Helm post-install output and modifies the migration artifact generator used during tenant cutovers; failures would mostly affect operator workflows and label accuracy rather than runtime behavior.
Overview
Fixes a Helm NOTES regression by rendering the Resource Monitor DaemonSet name via
tracebloc.resourceMonitorName(release-scoped) instead of a hardcodedtracebloc-resource-monitor, and adds a Helm unittest suite to prevent the literal name from reappearing and to verifyresourceMonitor: falsesuppresses the line.Improves migration tooling correctness by having
docs/migration-tools/generate.shparse chartname/versionfromclient/Chart.yamland stamp generated PVC manifests with matchingapp.kubernetes.io/versionandhelm.sh/chartlabels; accompanying docs/runbook text is updated to reflect the currentclient-1.2.0+guidance.Reviewed by Cursor Bugbot for commit 8ba1b2d.
