POTENTIAL ISSUES (12)

Issues with moderate confidence (4–7/10). Review manually — may be false positives.

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue block) - Cleanup success check is always True due to failed_when: false (confidence: 7/10)

failed_when: false forces gcp_disk_cleanup_result.failed = False unconditionally, so not gcp_disk_cleanup_result.failed is always True. The fail message always prints "Disk cleanup: succeeded" — even when the GCP API returned an error and the orphaned disk was NOT deleted. The "skipped or failed — check for orphaned disk" branch is dead code. Fix: Check a module-specific key for cleanup outcome, e.g. gcp_disk_cleanup_result.state == 'absent'. Or set a boolean fact before/after the cleanup step and check that instead.

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue, when: gcp_disk_result is defined) - Guard is a no-op; cleanup runs even if disk creation failed (confidence: 6/10)

In Ansible, register captures results even on task failure, so gcp_disk_result is always defined inside the rescue block — including when the disk task itself failed and no disk was created. Cleanup then runs against a non-existent disk and the message misleadingly reports success. Fix: when: gcp_disk_result is defined and not gcp_disk_result.failed

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue, "GCP: Fail after cleanup") - ansible_failed_result.msg may leak GCP API error details (confidence: 6/10)

GCP API errors routinely echo back request context in their bodies. Surfacing ansible_failed_result.msg verbatim flows to CI logs and any log aggregators. Fix: msg: "GCP resource creation failed. See GCP console for details. Disk cleanup: {{ ... }}" — or gate raw error on verbosity: 3.

MEDIUM roles/cloud-resources/tasks/digitalocean.yml (lines ~107, ~150) - No automated test for deduplication logic (confidence: 7/10)

| unique introduces a code path producing 1 tag vs. 2 tags depending on server_name. Manual MR checkboxes cover happy paths, but no Molecule test asserts the resolved list has 1 element when server_name=dblab and 2 elements otherwise. Suggestion: Add a Molecule test scenario covering both cases.

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue block) - No automated test for the rescue/cleanup path (confidence: 7/10)

The rescue block introduces new IaC error-handling behavior. Manual test confirms the happy rescue path but doesn't cover: (a) cleanup failure inside rescue, (b) whether a task failure before instance creation triggers rescue and deletes a disk that should not be deleted. Suggestion: Add a Molecule scenario simulating instance creation failure.

LOW roles/cloud-resources/tasks/digitalocean.yml (lines ~107, ~150) - No test or guard for empty server_name (confidence: 4/10)

['dblab', '' | lower] | unique produces ['dblab', ''] — an empty-string tag that may be invalid for the DigitalOcean API. Suggestion: Add a validation task or integration test for empty/whitespace server_name.

INFO roles/cloud-resources/tasks/gcp.yml (new block) - Named block inconsistent with codebase convention (confidence: 6/10)

All other blocks in gcp.yml and peer task files use anonymous - block:. The new block introduces name:, deviating from the established pattern. Suggestion: Remove the name: from the outer block; use a comment header instead.

INFO roles/cloud-resources/tasks/gcp.yml and digitalocean.yml - Tags: multi-line YAML list replaced by inline Jinja2 expression (confidence: 5/10)

The inline "{{ [...] | unique }}" works correctly but is stylistically inconsistent with labels:, disks:, and other list parameters in the same files. Suggestion: Pre-compute via set_fact (e.g., server_tags: "{{ ['dblab', server_name | lower] | unique }}") and reference "{{ server_tags }}" inline.

INFO roles/cloud-resources/tasks/gcp.yml (new block/rescue zone fields) - Zone comment omitted (confidence: 5/10)

All four existing zone: lines in gcp.yml carry # add "-b" if the zone is not defined. The new tasks omit this comment. Suggestion: Add the comment to all new zone: lines.

INFO roles/cloud-resources/tasks/digitalocean.yml (lines ~107, ~150) - Tags style deviation (confidence: 4/10)

Same style inconsistency: explicit YAML list replaced by inline Jinja2 string. Suggestion: Use set_fact + reference pattern (same as GCP suggestion above).

LOW roles/cloud-resources/tasks/digitalocean.yml (lines ~107, ~150) - Inline comment "matches any existing tag" is imprecise (confidence: 5/10)

| unique operates only on the constructed two-element list, not on all existing droplet tags. "Any existing tag" overstates the scope. Suggestion: # unique deduplicates within this list in case server_name == 'dblab'

LOW roles/cloud-resources/tasks/gcp.yml (rescue block, fail task) - "surfaces both outcomes" comment vague (confidence: 4/10)

A reader must infer what "both outcomes" means. Suggestion: # The 'fail' task re-raises the original error; if cleanup also failed, that error will appear in the rescue output above it.

BLOCKING ISSUES (4)

Issues that must be addressed before merge.

HIGH roles/cloud-resources/tasks/gcp.yml — Orphaned disk NOT cleaned up on re-run after prior failure

The rescue block guard when: gcp_disk_result is defined and gcp_disk_result.changed only triggers cleanup when the disk was created in the current run (changed: true). On any re-run after a prior failure (disk already exists → changed: false), cleanup is silently skipped and the orphaned disk remains permanently. This is the exact failure scenario the MR aims to fix — it works only on the very first failure run.

Fix: Replace the when guard with a check that the disk exists, not just that it was changed:

when: gcp_disk_result is defined and (gcp_disk_result.changed or gcp_disk_result.selfLink is defined)

Or remove the when entirely and rely on state: absent idempotency (GCP handles delete of non-existent disk gracefully with failed_when: false).

---

HIGH roles/cloud-resources/tasks/gcp.yml — No automated test for the rescue/cleanup path

The new block/rescue construct introduces critical logic (disk deletion guard, re-raise with diagnosis message) with no corresponding Molecule test. The MR test plan lists manual testing only. The rescue path exercises cloud resource deletion — without automated tests, regressions in the cleanup logic will go undetected.

Fix: Add a Molecule scenario that stubs google.cloud.gcp_compute_instance to fail and asserts: (a) the disk cleanup task runs when gcp_disk_result.changed == true; (b) cleanup is skipped (not errored) when gcp_disk_result is undefined; (c) the play terminates with a descriptive error message.

---

HIGH roles/cloud-resources/tasks/gcp.yml — changed: false guard not tested for re-run idempotency

The guard gcp_disk_result.changed is the critical safety switch for cleanup, yet there is no test covering the path where changed == false (disk pre-existed or re-run scenario) and instance creation then fails. Without this test the re-run bug above cannot be caught by CI.

Fix: Add a Molecule test case: disk already exists (changed=false) + instance creation fails → verify cleanup is appropriately skipped or handled, and the error message reflects the correct state.

---

MEDIUM roles/cloud-resources/tasks/gcp.yml — DATA LOSS GUARD comment omits the re-run edge case

The comment reads: "If the disk pre-existed the play run (changed == false), we must NOT delete it — doing so would destroy customer data." This is correct for a truly pre-existing disk, but the same changed: false condition also occurs on re-run after a prior failed play — where the disk was created by this playbook's previous run, is orphaned, and should be cleaned up. The comment frames the guard as fully safe when it actually leaves a known operational gap.

Fix: Amend the comment to acknowledge the re-run edge case:

# DATA LOSS GUARD: only delete the disk if THIS run created it (changed == true).
# NOTE: On re-run after a prior failure, the disk already exists (changed == false),
# so cleanup will again be skipped — orphaned disk must be removed manually in that case.
# This guard protects against deleting a disk that pre-dated this play.

---

POTENTIAL ISSUES (12)

Issues with moderate confidence (4–7/10). Review manually — may need context.

HIGH roles/cloud-resources/tasks/gcp.yml — ansible_failed_result.msg may expose service account credentials (confidence: 7/10)

The rescue fail task includes Error: {{ ansible_failed_result.msg | default('unknown error') }}. When a GCP module fails, ansible_failed_result can include invocation.module_args containing service_account_contents (the full GCP service account JSON). This message is written to stdout, CI logs, and notification integrations in plaintext. Suggestion: Remove ansible_failed_result.msg from the fail message, or use no_log: true on the fail task, and log diagnostics separately via a debug task with restricted access.

MEDIUM roles/cloud-resources/tasks/gcp.yml — Disk partially created on GCP API timeout → cleanup silently skipped (confidence: 6/10)

If GCP accepts the disk creation request but the Ansible module times out or receives an error response, the disk may exist on GCP while gcp_disk_result.changed is false (task failed). The rescue guard skips cleanup, leaving an orphaned disk with no indication in the failure message. Suggestion: Unconditionally attempt disk cleanup in rescue (removing the when guard) — state: absent with failed_when: false handles a non-existent disk gracefully, making this a safe no-op.

LOW roles/cloud-resources/tasks/digitalocean.yml — Tags comment overstates what | unique does (confidence: 5/10)

The comment # unique deduplicates in case server_name matches any existing tag implies the filter guards against collisions with tags already on the droplet. It only deduplicates within the newly constructed two-element list — no comparison to existing droplet tags occurs. Suggestion: # | unique prevents duplicate if server_name equals 'dblab'

MEDIUM roles/cloud-resources/tasks/digitalocean.yml — No test for | unique deduplication when server_name=dblab (confidence: 7/10)

The entire motivation of the DigitalOcean change is that server_name=dblab previously failed. There is no automated test asserting that when server_name is dblab (or DBLAB), the resulting tags list has exactly one element, and that other names still produce both tags. Suggestion: Add an assert task or Molecule verify step parameterized with server_name: dblab and server_name: myserver.

MEDIUM roles/cloud-resources/tasks/gcp.yml — No test for GCP | unique deduplication on tags (confidence: 6/10)

The same deduplication was applied to GCP tags.items. No test verifies the rendered list structure is correct for the GCP API, nor that the collision case (server_name: dblab) produces a single-element list. Suggestion: Add Molecule verify step asserting correct tags.items for both the collision and non-collision cases.

INFO roles/cloud-resources/tasks/digitalocean.yml — DRY violation: tags expression duplicated in two tasks (confidence: 7/10)

"{{ ['dblab', server_name | lower] | unique }}" is copy-pasted verbatim in both the default-VPC and with-VPC droplet tasks. Suggestion: Extract to a variable (droplet_tags) set via set_fact or in vars/main.yml.

INFO roles/cloud-resources/tasks/digitalocean.yml and roles/cloud-resources/tasks/gcp.yml — Comment inaccurate on | unique scope (confidence: 7/10)

Both files use # unique deduplicates in case server_name matches any existing tag. The unique filter has no knowledge of existing resource tags; it only deduplicates within the literal ['dblab', server_name | lower] list. Suggestion: Correct to: # | unique prevents duplicate if server_name equals 'dblab'

INFO roles/cloud-resources/tasks/digitalocean.yml — Asymmetry: GCP gets block/rescue, DigitalOcean does not (confidence: 6/10)

The MR title mentions fixing orphaned resources, but only GCP receives a cleanup block. DigitalOcean droplet creation is atomic (no pre-created separate disk), so this asymmetry is likely correct — but it is not documented. Suggestion: Add a brief comment explaining why DigitalOcean does not need a rescue block: # DigitalOcean droplet creation is atomic — no separate pre-created disk can become orphaned

INFO roles/cloud-resources/tasks/digitalocean.yml — Tags changed from YAML list to Jinja string without explanation (confidence: 5/10)

All other list-valued module parameters in the same files use YAML block list syntax. The format change to an inline Jinja string is a style divergence that may confuse maintainers. Suggestion: Add a comment explaining the format change: # Jinja2 expression instead of a literal YAML list so | unique can be applied

LOW roles/cloud-resources/tasks/gcp.yml — No comment explaining why tasks were wrapped in a block (confidence: 6/10)

The outer block task name describes what it does, but there is no comment explaining why the two tasks were grouped (i.e., to enable the rescue handler). Suggestion: Add above the block: # Block enables rescue handler to clean up orphaned disk if instance creation fails

LOW roles/cloud-resources/tasks/digitalocean.yml — Tags comment doesn't explain format change from YAML list (confidence: 5/10)

The comment explains deduplication but not why the YAML list was replaced with a Jinja2 expression string. Suggestion: # Jinja2 expression (instead of YAML list) so | unique can deduplicate if server_name == 'dblab'

LOW roles/cloud-resources/tasks/gcp.yml — Fail msg conflates "skipped" and "failed" cleanup outcomes (confidence: 4/10)

The cleanup status string outputs 'skipped or failed' for two distinct conditions (cleanup skipped by when guard vs. cleanup attempted but failed). Post-mortem diagnosis requires distinguishing these cases. Suggestion: Use separate conditions for "skipped" vs. "failed" in the message, or add a comment noting the intentional conflation.

BLOCKING ISSUES (4)

Issues that must be addressed before merge.

---

HIGH roles/cloud-resources/tasks/gcp.yml - Rescue block deletes storage disk unconditionally, including pre-existing disks — data loss risk on re-runs

rescue:
  - name: "GCP: Clean up disk '{{ server_name }}-storage' after failed resource creation"
    google.cloud.gcp_compute_disk:
      name: "{{ server_name }}-storage"
      state: absent
    when: gcp_disk_result is defined   # always True; does NOT guard pre-existing disks

If the disk pre-existed this play (e.g. re-running after a previous partial deploy), gcp_compute_disk returns changed: false, yet the rescue still deletes it. Scenario: disk exists with data → gcp_compute_instance fails (quota/network) → rescue fires → disk deleted → data loss. The rescue comment even acknowledges this: "regardless of whether it was newly created this run or already existed" — that is the problem.

Fix: Use when: gcp_disk_result is defined and gcp_disk_result.changed so the rescue only deletes disks that were actually created by this playbook run. Additionally, gcp_disk_result is defined is always True inside the rescue (Ansible registers variables even from failed tasks), making it an ineffective guard.

---

HIGH roles/cloud-resources/tasks/gcp.yml - Rescue block (orphaned disk cleanup) has no automated test — critical new error-handling path is untested

The most significant new behavior introduced by this MR — the block/rescue that deletes a GCP disk on instance creation failure — has no molecule scenario covering it. The manual test plan marks "rescue path tested: disk cleaned up on failure (rescued=1)" but this is not a repeatable, automated regression guard. Infrastructure error-handling code that performs destructive operations (disk deletion) requires automated coverage.

Fix: Add a molecule scenario that injects an instance-creation failure (mock the GCP instance module to return failed: true) and asserts: (a) the disk cleanup task ran, (b) the disk is absent afterward, and (c) the play ends in failure (not silent success).

---

HIGH roles/cloud-resources/tasks/digitalocean.yml + gcp.yml - No regression test for the server_name=dblab deduplication fix — the exact bug this MR fixes

The MR fixes a duplicate-tag bug triggered when server_name equals "dblab". There is no automated test asserting that server_name=dblab results in a single dblab tag rather than two. Without this, the fix can silently regress.

Fix: Add a molecule test with server_name: "dblab" asserting tags: ["dblab"] (one element). Add a second case with server_name: "other" asserting tags: ["dblab", "other"] to confirm the normal case is unaffected.

---

MEDIUM roles/cloud-resources/tasks/gcp.yml - Rescue block comment states disk is deleted "regardless of whether it was newly created" without warning this constitutes a destructive operation on pre-existing infrastructure

The inline comment normalises the unconditional deletion of a potentially pre-existing disk. Any operator reading this code needs an explicit warning that this can cause data loss in re-run scenarios.

Fix: Add an explicit warning: # WARNING: if gcp_disk_result.changed is false the disk pre-existed this play — deleting it will cause data loss. Only delete when gcp_disk_result.changed is true. (and fix the conditional as noted above).

---

POTENTIAL ISSUES (13)

Issues with moderate confidence (4–7/10). Review manually — may be false positives.

MEDIUM digitalocean.yml:107,148 - Comment # unique deduplicates in case server_name matches any existing tag is inaccurate (confidence: 7/10)

| unique deduplicates within the constructed list only, not against tags already on the droplet. Suggestion: # unique deduplicates within this list — guards against server_name equalling 'dblab'

MEDIUM gcp.yml rescue fail task - failed_when: false comment does not provide operational runbook (confidence: 7/10)

Operators responding to an incident need to know the play continues after cleanup failure and what manual remediation to perform (e.g. gcloud compute disks delete).

MEDIUM digitalocean.yml:107,148 - Silent tag deduplication behavioral change not documented for operators (confidence: 6/10)

Previously two entries were always passed; now a duplicate is silently dropped. Suggestion: # Previously passed two entries even if identical; unique ensures the API receives a deduplicated list

MEDIUM gcp.yml - auto_delete: true on storage disk means GCP deletes data disk when instance is deleted (confidence: 6/10, pre-existing)

The storage disk is explicitly managed via gcp_compute_disk as a separate lifecycle resource, yet auto_delete: true means GCP silently destroys it on instances.delete.

MEDIUM gcp.yml - No test for mixed-case server_name through the lower + unique pipeline (confidence: 7/10)

server_name: "DBLAB" should produce one tag; no test covers this.

MEDIUM gcp.yml - Rescue cleanup failure path not tested (confidence: 6/10)

No test verifies the play fails loudly if the disk delete inside rescue also fails.

MEDIUM digitalocean.yml - VPC branch not tested with server_name=dblab (confidence: 5/10)

Fix applies to both droplet tasks but test plan doesn't cover the VPC path for the deduplication scenario.

LOW gcp.yml - Block name "GCP: Create or modify disk and instance" misleading in rescue log output (confidence: 5/10)

Suggestion: "GCP: Create or modify disk and instance for '{{ server_name }}' (with cleanup on failure)"

LOW digitalocean.yml:107,148 - Duplicate comments may drift independently (confidence: 5/10)

Suggestion: Consolidate tag construction into a set_fact task.

LOW gcp.yml - ansible_failed_result.msg in rescue fail message may expose GCP project IDs and resource paths in CI logs (confidence: 5/10)

Ensure CI log storage is access-controlled.

INFO digitalocean.yml:107,148 - tags changed from YAML list syntax to Jinja2 string expression — style inconsistency with rest of file (confidence: 7/10)

Suggestion: Use a set_fact task to construct tags, keeping native YAML list syntax.

INFO gcp.yml - Named block inconsistent with anonymous blocks used everywhere else in both task files (confidence: 6/10)

Suggestion: Remove the name: or add names to all blocks in a separate housekeeping commit.

INFO gcp.yml - | unique non-idiomatic for this codebase; no other list uses it (confidence: 6/10)

Suggestion: set_fact: gcp_tags: "{{ ['dblab', server_name | lower] | unique }}" then reference tags.items: "{{ gcp_tags }}".

Review Status

This thread blocks merge until review is complete.

Checklist:

• Code reviewed by a team member (not the author)
• MR approved in GitLab
• Changes verified / tested as appropriate

Resolve this thread after completing review to unblock merge. SOC2 DCF-5: Changes must be peer-reviewed and approved prior to deployment.

Summary

Closes #64

Replace all :latest Docker image tags with explicit pinned versions to improve reproducibility in CI, testing, and deployment.

Changes

• alpine:latest → alpine:3.21 (CI lint, SQL security, preview jobs)
• postgresai/monitoring-flask-backend:latest → postgresai/monitoring-flask-backend:0.14.0 (Helm values)
• traefik:latest → traefik:v3.6.10 (preview-infra compose)

Not in scope (untracked files)

• reporter/build-multiarch.sh — also has a latest tag in TAGS array (edited locally, not yet committed to repo)
• terraform/hetzner/variables.tf — pgai_tag default is "latest" (edited locally, not yet committed to repo)
• .gitlab-ci.yml DIST_TAG="latest" — this is the npm dist-tag convention (not a Docker tag), correct behavior for npm publish

Remaining registry cleanup

• latest tags should be deleted from the container registry (manual step)

Test plan

• Verify CI pipeline passes with pinned alpine:3.21
• Verify Helm chart deploys correctly with monitoring-flask-backend:0.14.0
• Verify preview-infra traefik starts with v3.6.10
• Delete latest tags from container registry

BLOCKING ISSUES (1)

HIGH roles/cloud-resources/tasks/gcp.yml (rescue block) — No automated test for new rescue/cleanup path

The rescue block is newly introduced critical code with failed_when: false suppression and a conditional guard. The MR description notes manual testing only (rescued=1). If the when: gcp_disk_result is defined guard or failed_when: false behavior changes subtly, no regression test would catch it. Fix: Add a molecule test scenario that simulates instance creation failure and asserts: (1) the disk cleanup task ran, (2) gcp_disk_cleanup_result is registered, and (3) the play fails with the expected message from ansible.builtin.fail.

---

POTENTIAL ISSUES (5)

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue block, cleanup task when condition) — when: gcp_disk_result is defined guard is always true inside rescue (confidence: 5/10)

In Ansible, register populates the variable even on task failure, so gcp_disk_result is always defined when rescue runs (the disk task always executes first in the block). The guard evaluates to True in all reachable cases, making it dead code rather than a meaningful guard. Suggestion: Either remove the guard (since state: absent on a non-existent GCP disk is idempotent) or replace it with when: gcp_disk_result is defined and not gcp_disk_result.failed | default(true) if the intent is to skip cleanup when disk creation itself failed.

MEDIUM roles/cloud-resources/tasks/digitalocean.yml:107 — No molecule regression test for server_name=dblab duplicate-tag fix (confidence: 7/10)

The | unique fix works but no automated test guards against regression. If the filter were accidentally removed in a future refactor, no CI check would catch it. Suggestion: Add a molecule test that sets server_name=dblab and asserts the resulting tags list has no duplicates (i.e., length 1, value ['dblab']). Cover both the server_network defined and undefined code paths.

MEDIUM roles/cloud-resources/tasks/gcp.yml (instance disks block) — Storage disk auto_delete: true risks data loss on instance deletion (confidence: 7/10, pre-existing)

The data/storage disk has auto_delete: true. Deleting the GCP instance will also permanently destroy the storage disk. For a database lab environment this could cause unintentional data loss if an operator deletes the instance expecting to recreate it. Suggestion: Confirm this is intentional for ephemeral lab environments; if not, set auto_delete: false for the storage disk. (Pre-existing issue, not introduced by this MR.)

LOW roles/cloud-resources/tasks/gcp.yml:~83 (block comment) — Block comment understates best-effort cleanup behavior (confidence: 5/10)

The comment says "the rescue block attempts to delete the orphaned disk so the next run can start clean" but omits that cleanup itself can silently fail (failed_when: false) and that the play always terminates in failure regardless of cleanup outcome. Suggestion: Extend the comment: "Cleanup is best-effort (failed_when: false); if it fails, the orphaned disk must be removed manually from the GCP console. The play always ends in failure."

LOW roles/cloud-resources/tasks/digitalocean.yml:107 — Inline comment narrowly describes the | unique guard (confidence: 4/10)

Comment says # unique prevents duplicate when server_name == 'dblab' but the filter protects against any collision between server_name and any existing tag (not just 'dblab'). Suggestion: # unique deduplicates in case server_name matches any existing tag in the list

BLOCKING ISSUES (3)

Issues that must be addressed before merge.

---

HIGH roles/cloud-resources/tasks/gcp.yml (rescue block, cleanup task) — ignore_errors: true violates Ansible guidelines; use failed_when: false

ignore_errors: true  # best-effort — if this fails, disk must be deleted manually from GCP console

The postgres-ai Ansible rule explicitly states: "Avoid using ignore_errors unless absolutely necessary, prefer failed_when". This is a direct, newly introduced violation. failed_when: false achieves the same best-effort cleanup behavior while properly setting failed on the registered result. Fix: Replace ignore_errors: true with failed_when: false. The gcp_disk_cleanup_result.failed check in the subsequent fail message already handles this correctly.

---

HIGH roles/cloud-resources/tasks/gcp.yml (rescue cleanup task, when condition) — Cleanup guard uses .changed but skips on idempotent re-run after partial failure

when: gcp_disk_result is defined and gcp_disk_result.changed

The comment says "If the disk already existed (idempotent re-run), don't delete it" — this is intentional for the happy idempotent case. However, it creates a gap: if the disk was created in run #1 (closed) (instance failed), and run #2 (closed) is attempted, gcp_disk_result.changed is false (disk already exists), so cleanup is skipped even though the disk exists and the instance still failed. The disk is effectively orphaned after any retry. Fix: Consider when: gcp_disk_result is defined and not gcp_disk_result.failed | default(true) — this cleans up whenever the disk is confirmed present (regardless of whether it was created now or already existed), which is the intent of an orphan-prevention rescue. If the "don't touch pre-existing disks" requirement is firm, document this limitation explicitly and accept it.

---

HIGH roles/cloud-resources/tasks/gcp.yml — No automated test for the rescue/cleanup path

The block/rescue is the primary new behavior in this MR. The CI pipeline completes in 8 seconds (YAML lint only). The rescue path has zero automated test coverage — only manual testing is documented. Critical infrastructure error-recovery code without automated tests risks silent regression on any future refactor. Fix: Add a Molecule test scenario (or equivalent IaC test) that: (1) mocks gcp_compute_instance to fail after gcp_compute_disk succeeds (changed=true); (2) asserts the cleanup task runs with state: absent; (3) asserts the play terminates as failed. Also add a contrasting scenario where gcp_disk_result.changed=false and verify the disk is not deleted.

---

NON-BLOCKING (3)

Minor issues and suggestions. Can be addressed in a follow-up.

---

INFO roles/cloud-resources/tasks/gcp.yml (line ~103, block:) — Missing comment explaining the block/rescue strategy

The block name only describes the happy path. Future maintainers will not immediately understand that the rescue exists to prevent orphaned billable GCP resources. Suggestion: Add a comment above block:: # block/rescue ensures storage disk is removed if instance creation fails, preventing orphaned billable GCP resources

---

INFO roles/cloud-resources/tasks/gcp.yml (rescue cleanup, when condition) — when guard has no comment explaining why .changed is required

when: gcp_disk_result is defined and gcp_disk_result.changed

Suggestion: Add inline comment: # only clean up if we created the disk in this run; if it pre-existed, leave it intact

---

INFO roles/cloud-resources/tasks/gcp.yml (rescue cleanup, ignore_errors/failed_when) — Operator comment lacks actionable runbook detail

The comment says "disk must be deleted manually from GCP console" but doesn't tell the operator which project, zone, or naming convention to look for. Suggestion: Expand to: # best-effort — on failure, delete disk '{{ server_name }}-storage' manually in GCP Console (project: gcp_project, zone: server_location). Raise a ticket to track orphaned resources.

---

POTENTIAL ISSUES (12)

Review manually — may be false positives or intentional design choices.

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue fail msg) — Operator precedence in Jinja2 expression is ambiguous (confidence: 5/10)

not gcp_disk_cleanup_result.failed | default(false) works correctly (| binds before not in Jinja2), but is easy to misread. Suggest explicit parentheses: not (gcp_disk_cleanup_result.failed | default(false))

HIGH roles/cloud-resources/tasks/gcp.yml (instance metadata) — SSH key injected for root user (confidence: 7/10 — pre-existing, not introduced by this MR)

ssh-keys: "root:{{ ssh_key_content }}" — direct root SSH access. Pre-existing pattern, unchanged by this MR. Consider GCP OS Login or a non-root service account in a future cleanup.

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue fail msg) — ansible_failed_result.msg is embedded in logs unvalidated (confidence: 5/10)

GCP API error messages could contain log-injection content if a SIEM parses Ansible output. Low real-world risk for private infrastructure but worth noting. Add | truncate(200) if log parsing is in use.

LOW roles/cloud-resources/tasks/digitalocean.yml and gcp.yml — server_name has no input validation before Jinja2 use (confidence: 4/10 — pre-existing)

| lower normalizes case but doesn't prevent Jinja2 metacharacters. Pre-existing pattern. Add an assert with a strict regex pattern (e.g., ^[a-z0-9-]{1,63}$) at playbook entry if server_name comes from untrusted input.

MEDIUM roles/cloud-resources/tasks/digitalocean.yml — | unique returns a list; verify community.digitalocean collection version handles list tags (confidence: 6/10)

Some older versions of the DigitalOcean collection pass tags as comma-joined strings via API. The fix is correct behavior-wise but worth confirming against the pinned collection version.

MEDIUM roles/cloud-resources/tasks/gcp.yml (rescue cleanup) — ignore_errors: true (to be replaced with failed_when: false) masks cleanup permission/quota errors from operator visibility (confidence: 5/10)

Regardless of which directive is used, failed cleanup is only surfaced in the fail message string. Consider adding a debug task before the final fail to explicitly log the cleanup result.

MEDIUM Tests — No CI test verifying server_name=dblab produces exactly one tag (confidence: 7/10)

The deduplication fix is the other core change but has no parameterized test. A Molecule scenario with server_name: dblab and assertion on tag count would catch regressions.

MEDIUM Tests — No CI integration test exercising GCP partial-failure rollback (confidence: 6/10)

Manual testing documented in MR description but not formalized. A CI stage in a test GCP project would gate future regressions.

MEDIUM Tests — No test verifying the play fails (not silently succeeds) when both instance creation and disk cleanup fail (confidence: 5/10)

The double-failure path relies on failed_when: false + fail task interaction being correct.

INFO roles/cloud-resources/tasks/gcp.yml (rescue block) — Auth/project/zone params duplicated verbatim from block into rescue (confidence: 5/10)

Violates DRY. Consider set_fact for shared GCP connection params at the role level.

INFO roles/cloud-resources/tasks/digitalocean.yml (lines ~107, ~148) — Inline trailing comment vs. preceding comment style (confidence: 4/10)

Ansible convention places comments on their own preceding line. Minor style issue.

INFO Role README — Block/rescue error-recovery behavior not documented (confidence: 4/10)

Operators deploying this role in pipelines should know partial failures hard-fail with automatic cleanup attempt.

NON-BLOCKING (2)

Minor issues and suggestions (high-confidence LOW, INFO severity). Can be addressed later.

INFO MR metadata - Commit type fix: may be more accurately feat:

This change introduces new functionality (new functions, new types, new preflight behavior). Per conventional commits, feat: = new functionality (MINOR bump), fix: = bug fix (PATCH bump). Suggestion: Consider feat(checkup): verify DB user permissions for correct semantic versioning.

INFO MR metadata - Title exceeds 50-character limit (53 chars)

Per postgres-ai git standards, commit subject should be under 50 characters. Suggestion: Shorten to e.g. feat(checkup): verify DB user permissions (41 chars).

---

POTENTIAL ISSUES (4)

Issues with moderate confidence (4-7/10). Review manually — may be false positives.

MEDIUM cli/bin/postgres-ai.ts:1840 - Database client not explicitly closed on early return (confidence: 6/10)

When permMessages.failed is true, the function returns with process.exitCode = 1 without calling client.end(). The connection persists until process exit. Since the process is about to terminate, Node.js will clean up the socket, but explicit cleanup is best practice. Suggestion: Add await client.end() before the early return, or verify the surrounding scope has a finally block.

MEDIUM cli/bin/postgres-ai.ts:1820 - CLI glue code (18 lines) has no direct test coverage (confidence: 7/10)

The orchestration code (call functions, iterate arrays, set process.exitCode) is untested. However, both pure functions it calls are thoroughly tested (16 tests total), and the remaining logic is trivial iteration. Suggestion: Consider adding a lightweight CLI-level test for the process.exitCode side effect on the failure path.

LOW cli/test/init.test.ts - No test for undefined granted value (confidence: 5/10)

Tests cover null and false but not undefined. If a malformed row omits granted, the filter granted !== true would catch it for required permissions, but this edge case is untested. TypeScript types mitigate this. Suggestion: Minor — add one test with granted: undefined as any if desired.

LOW cli/test/init.test.ts - No test for empty string fix_command (confidence: 5/10)

Tests cover string and null but not "". The .filter(Boolean) in formatPermissionCheckMessages correctly handles this, but it's untested. Suggestion: Minor — add one test with fix_command: "" to verify it's treated as absent.

BLOCKING ISSUES (3)

Issues that must be addressed before merge.

HIGH roles/cloud-resources/tasks/gcp.yml — Credential leakage in rescue error message

ansible_failed_result | string serializes the full failed task invocation dict into the error message — including service_account_contents (GCP service account JSON key), SSH key material, and any other module args. This gets emitted to CI/CD job logs, stdout, and any log aggregator.

msg: "... Error: {{ ansible_failed_result.msg | default(ansible_failed_result | string) }}"

Fix: Replace the | default(ansible_failed_result | string) fallback with | default('no message available'). Only ever use ansible_failed_result.msg — never serialize the full result object.

---

HIGH roles/cloud-resources/tasks/gcp.yml — No automated test for rescue path

The rescue block (disk cleanup on instance creation failure) is a new critical code path with no Molecule scenario or CI test. The MR test plan states "rescued=1" as evidence, but this is a one-time manual observation — not a repeatable automated test. The following paths are unvalidated: (a) rescue fires correctly, (b) disk is actually deleted, (c) if disk deletion also fails (ignore_errors: true), the operator has no way to detect it.

Fix: Add a Molecule scenario that simulates gcp_compute_instance failure after gcp_compute_disk succeeds, and asserts: disk cleanup task runs, disk cleanup result is captured, final fail message reflects cleanup outcome.

---

MEDIUM roles/cloud-resources/tasks/digitalocean.yml + gcp.yml — No automated test for core bug fix

The primary fix (deduplicate tags when server_name == "dblab") is verified only via a manual deployment. There is no repeatable test asserting the rendered tags list has length 1 when server_name: "dblab".

Fix: Add a Molecule test or ansible-playbook --check assertion: given server_name: "dblab", assert resulting tags equals ["dblab"] (not ["dblab", "dblab"]).

---

NON-BLOCKING (2)

INFO roles/cloud-resources/tasks/gcp.yml — Zone expression duplicated in rescue block

The zone expression "{{ server_location + '-b' if not server_location is match('.*-[a-z]$') else server_location }}" now appears three times (disk task, instance task, rescue cleanup task). The file already uses ansible.builtin.set_fact for gcp_network_name just above this block — same pattern applies here.

Suggestion: Add set_fact: gcp_zone: "{{ server_location + '-b' if not server_location is match('.*-[a-z]$') else server_location }}" before the block and reference {{ gcp_zone }} throughout.

---

LOW roles/cloud-resources/tasks/gcp.yml — Rescue when guard conditions undocumented

when: gcp_disk_result is defined and gcp_disk_result.changed contains two non-obvious guards. Without explanation, future maintainers may simplify to just .changed and break the path where the disk task itself fails (where gcp_disk_result would be undefined).

Suggestion: Add inline comment:

# 'is defined': disk task may not run if it errored before registering a result
# '.changed': only delete if WE created it this run (not a pre-existing disk)

---

POTENTIAL ISSUES (16)

Issues with moderate confidence (4-7/10). Review manually — may be context-dependent or pre-existing.

CRITICAL roles/cloud-resources/tasks/gcp.yml — Pre-existing: initialize_params may conflict with pre-created disk (confidence: 6/10)

gcp_compute_disk creates {{ server_name }}-storage, then gcp_compute_instance uses initialize_params: disk_name: "{{ server_name }}-storage". On first deployment, the GCP Instances API may return a 409 Conflict when trying to create a disk that already exists. Note: baseline tests reportedly pass with this pattern — verify google.cloud.gcp_compute_instance module behavior with pre-existing disks. Suggestion: If confirmed buggy: attach via source: selfLink: "{{ gcp_disk_result.selfLink }}" instead of initialize_params.

HIGH roles/cloud-resources/tasks/gcp.yml — Pre-existing: storage disk auto_delete: true may cause data loss (confidence: 6/10)

Storage disk is configured with auto_delete: true — GCP destroys it when the instance is deleted. This may be intentional for ephemeral DBLab environments, but if the storage disk should survive instance teardown, this needs to be false. Suggestion: Confirm this is intentional; if not, set auto_delete: false for the -storage disk.

MEDIUM roles/cloud-resources/tasks/gcp.yml — Rescue cleanup outcome not reflected in fail message (confidence: 6/10)

The fail message always states "Attempted disk cleanup" regardless of whether cleanup succeeded, was skipped, or itself failed silently (ignore_errors: true). Operators have no way to know if an orphaned disk remains in GCP. Suggestion: Register the cleanup task result and include its outcome in the fail message.

MEDIUM roles/cloud-resources/tasks/digitalocean.yml — Mixed-case server_name edge cases not tested (confidence: 7/10)

| lower handles normalization but values like DBLAB, Dblab are not in the test plan and have no Molecule coverage. Suggestion: Add parametrized tests for DBLAB, Dblab, DBLAB2.

MEDIUM roles/cloud-resources/tasks/gcp.yml — Disk-create-fails path untested in rescue (confidence: 7/10)

If gcp_compute_disk itself fails, gcp_disk_result may be undefined or have changed: false. The is defined guard should prevent erroneous cleanup, but this path is not tested. Suggestion: Add Molecule scenario where the disk creation task fails; assert rescue fires with cleanup correctly skipped.

MEDIUM roles/cloud-resources/tasks/gcp.yml — GCP path with server_name=dblab not in test plan (confidence: 6/10)

Only DigitalOcean was mentioned in the test plan for the server_name=dblab case. GCP tag deduplication is untested on this path.

INFO roles/cloud-resources/tasks/gcp.yml — Block name redundantly repeats GCP: prefix (confidence: 7/10)

Parent block named "GCP: Create or modify disk and instance for '{{ server_name }}'" while all child tasks also start with GCP: ... '{{ server_name }}'. The prefix and variable are repeated in all log output. Suggestion: Shorten block name or drop it (blocks do not require names).

INFO roles/cloud-resources/tasks/gcp.yml — ignore_errors: true should be failed_when: false (confidence: 6/10)

ignore_errors: true suppresses all errors unconditionally, including auth failures or quota errors where suppression is undesirable. Standard Ansible linting flags this (risky-ignore-errors). Suggestion: Use failed_when: false — semantically equivalent but lint-clean.

INFO roles/cloud-resources/tasks/gcp.yml — Rescue when may skip cleanup on partially-created disk (confidence: 5/10)

If the disk task partially succeeds then fails, gcp_disk_result.changed may be false even though GCP created the disk. Cleanup would be skipped. Suggestion: Consider when: gcp_disk_result is defined and (gcp_disk_result.changed or gcp_disk_result.failed | default(false)).

INFO roles/cloud-resources/tasks/gcp.yml — server_result / gcp_disk_result naming inconsistency (confidence: 5/10)

New disk task registers as gcp_disk_result (provider-prefixed) while existing instance task retains server_result (generic). Track as naming debt.

LOW roles/cloud-resources/tasks/gcp.yml — # best-effort cleanup comment too minimal (confidence: 7/10)

Does not explain consequence of failure (orphaned disk requires manual cleanup in GCP console). Suggestion: # best-effort cleanup — if this fails, disk '{{ server_name }}-storage' must be deleted manually from GCP console

LOW roles/cloud-resources/tasks/gcp.yml — Block name hides rescue/cleanup semantics (confidence: 7/10)

Nothing in the block's name indicates a rescue/cleanup mechanism exists. Suggestion: Rename to "GCP: Create disk and instance for '{{ server_name }}' (disk cleanup on failure)" or add a comment above.

LOW roles/cloud-resources/tasks/gcp.yml — Rescue magic variables not documented as context-dependent (confidence: 6/10)

ansible_failed_task and ansible_failed_result are only populated inside a rescue block. Moving the fail task outside rescue (e.g., refactoring) would silently produce empty values. Suggestion: Add comment: # ansible_failed_task/result are rescue-only magic variables — do not move outside rescue

LOW roles/cloud-resources/tasks/digitalocean.yml — Tags as Jinja2 string relies on Ansible list coercion (confidence: 5/10)

Changing from native YAML list to quoted Jinja2 string relies on Ansible's template-to-list type coercion. Differs from YAML list style used elsewhere in the file.

LOW roles/cloud-resources/tasks/digitalocean.yml — Special characters in server_name not tested (confidence: 5/10)

| lower does not strip invalid tag characters (spaces, !, etc.). Behavior with server_name: "db lab" is undocumented.

INFO roles/cloud-resources/ — No CHANGELOG/README update for operational changes (confidence: 4/10)

Tag deduplication and GCP disk auto-cleanup are meaningful behavioral changes that on-call engineers should be aware of. Neither is reflected in role-level documentation.

BLOCKING ISSUES (2)

Issues that must be addressed before merge (high-confidence CRITICAL, HIGH, MEDIUM severity).

HIGH cli/lib/init.ts — pg_has_role() will throw a runtime error if pg_monitor role does not exist

The SQL uses exists (...) and pg_has_role(current_user, 'pg_monitor', 'member'). SQL does not guarantee short-circuit evaluation of AND — PostgreSQL may evaluate pg_has_role() before the EXISTS check. If pg_monitor does not exist (PostgreSQL < 10, or explicitly dropped), pg_has_role() raises ERROR: role "pg_monitor" does not exist, crashing the entire preflight query. Fix: Replace with a CASE WHEN to guarantee evaluation order:

case
  when not exists (select from pg_roles where rolname = 'pg_monitor')
  then false
  else pg_has_role(current_user, 'pg_monitor', 'member')
end as granted

HIGH cli/bin/postgres-ai.ts:1820 — CLI integration path (32 lines) has zero test coverage

The 9 unit tests cover only the pure checkCurrentUserPermissions function. The CLI orchestration — spinner updates, console.error warnings/errors, process.exitCode = 1, and early return — is entirely untested. Fix: Add CLI-level tests that mock the DB client and verify: (a) process.exitCode is set to 1 when ok is false; (b) warnings are printed for missing optional permissions; (c) normal flow continues when all permissions are granted.

---

POTENTIAL ISSUES (9)

Issues with moderate confidence (4-7/10). Review manually — may be false positives.

MEDIUM cli/lib/init.ts — format('%s', ...) should use %I for identifier quoting in fix_commands (confidence: 6/10)

The generated fix_commands use format('grant connect on database %s to %s;', current_database(), current_user). The %s specifier does not quote identifiers. If database/user names contain special characters, the output SQL could be malformed or injectable — and users are told to run it as superuser. Suggestion: Use %I (applies quote_ident()) instead of %s in all format() calls for identifiers.

MEDIUM cli/bin/postgres-ai.ts:1820 — No error handling around the preflight query call (confidence: 7/10)

If checkCurrentUserPermissions(client) throws (e.g., due to the pg_has_role bug above, or a network error), the spinner is left running and the error propagates as an unhandled exception with a raw stack trace. Suggestion: Wrap in try/catch with spinner.stop() and a user-friendly error message, or verify the surrounding code already handles this.

MEDIUM cli/test/init.test.ts — Mock client ignores SQL arguments; deleted SQL would still pass (confidence: 6/10)

makeMockClient returns pre-canned rows regardless of the SQL string. No test asserts the SQL query is actually sent. Suggestion: Add at least one assertion on the SQL argument to catch accidental query deletion.

MEDIUM cli/test/init.test.ts — Error propagation test only checks message substring (confidence: 5/10)

rejects.toThrow("permission denied...") doesn't verify the original error object is preserved (same instance, type, .code). Suggestion: Assert the rejected error is the same object or verify additional properties.

LOW cli/lib/init.ts — Asymmetric null handling between required/optional filters (confidence: 5/10)

Required uses granted !== true (null = missing), optional uses granted === false (null = skipped). Intentional but undocumented asymmetry is a maintenance hazard. Suggestion: Add a code comment explaining the intentional difference.

LOW cli/lib/init.ts — Missing @throws documentation (confidence: 4/10)

The function can throw on query errors but the JSDoc doesn't document the rejection path. Suggestion: Add @throws noting that database errors propagate to the caller.

INFO MR metadata — Commit type fix: may be more accurately feat: (confidence: 7/10)

This change introduces new functionality (new function, types, preflight behavior). Per conventional commits, feat: = new functionality (MINOR bump), fix: = bug fix (PATCH bump). If the missing check is framed as a bug, that framing should be explicit in the commit body. Suggestion: Consider feat(checkup): add DB user permission preflight check.

INFO MR metadata — Scope omitted from commit subject (confidence: 7/10)

Per postgres-ai standards, scope syntax is encouraged. Recent commits use scopes consistently. Suggestion: Add scope: feat(checkup): ... or fix(checkup): ....

INFO MR metadata — Title exceeds 50-character limit (confidence: 5/10)

At 53 characters, the title slightly exceeds the project's 50-character limit for commit subjects. Suggestion: Shorten to e.g. feat(checkup): add DB permission preflight (43 chars).

BLOCKING ISSUES (3)

Issues that must be addressed before merge.

HIGH roles/cloud-resources/tasks/gcp.yml - Rescue unconditionally deletes potentially pre-existing disk

The rescue block deletes {{ server_name }}-storage with state: absent regardless of whether the disk was newly created by this run or already existed from a previous deployment. If the playbook is re-run against an existing server (idempotent state: present) and instance creation fails for any reason (quota exceeded, machine type unavailable, network error), the rescue will permanently destroy the pre-existing data disk.

Evidence:

rescue:
  - name: "GCP: Clean up disk '{{ server_name }}-storage' after failed instance creation"
    google.cloud.gcp_compute_disk:
      ...
      state: absent
    ignore_errors: true

Fix: Register the disk creation result and only delete if the disk was actually created in this run (changed: true):

- name: "GCP: Create or modify disk '{{ server_name }}-storage'"
  google.cloud.gcp_compute_disk:
    ...
  register: gcp_disk_result

rescue:
  - name: "GCP: Clean up disk '{{ server_name }}-storage' after failed instance creation"

HIGH roles/cloud-resources/tasks/gcp.yml - Rescue cleanup failure scenario untested; error message is misleading

Two issues in the fail message:

1. The rescue executes when either disk creation or instance creation fails, but the message hardcodes "GCP instance creation failed" — if the disk task fails, this message is incorrect.
2. The | default('unknown error') fallback will silently hide the root cause if ansible_failed_result lacks a msg key (e.g., API 5xx, quota errors, network failures in some GCP module versions).

Evidence:

msg: "GCP instance creation failed. The storage disk has been cleaned up. Error: {{ ansible_failed_result.msg | default('unknown error') }}"

Fix: Make the message generic and include the task name for diagnostics:

msg: "GCP resource creation failed (task: {{ ansible_failed_task.name | default('unknown') }}). Attempted disk cleanup. Error: {{ ansible_failed_result.msg | default(ansible_failed_result | string) }}"

MEDIUM roles/cloud-resources/ - No documented constraint on server_name values

The role silently deduplicates when server_name=dblab but there is no documentation (README, defaults/main.yml comments, or task comments) explaining this constraint. Operators who choose server_name=dblab will get a functioning deployment now (thanks to this fix), but won't understand why deduplication happens or what other internal values may clash. Future maintainers reading the | unique filter have no context for why it's needed.

Fix: Add to the role README or defaults/main.yml:

# server_name: Name for the DBLab instance. Note: 'dblab' is a reserved internal
# tag value; if server_name equals 'dblab', duplicate tags are silently removed
# via | unique. See: postgres-ai/platform-ui#108

NON-BLOCKING (1)

INFO roles/cloud-resources/tasks/gcp.yml - Block wrapper task name breaks established naming convention

All other GCP task names follow the pattern "GCP: Create or modify <resource> '{{ server_name }}'" (idempotency-signaling verb + resource reference). The new block wrapper uses "GCP: Create disk and instance" — it drops or modify, omits '{{ server_name }}', and in multi-host play output will be ambiguous across hosts.

Suggestion: Rename to: "GCP: Create or modify disk and instance for '{{ server_name }}'"

POTENTIAL ISSUES (5)

Issues with moderate confidence (4-7/10). Review manually — may be context-dependent.

HIGH roles/cloud-resources/tasks/gcp.yml - Double-failure scenario: disk cleanup fails silently (confidence: 7/10)

ignore_errors: true on the rescue cleanup means if disk deletion fails (IAM permission, disk in use), the subsequent fail message says "disk has been cleaned up" — which is false. The orphaned disk remains but the operator has no alert.

Suggestion: Register the cleanup result and add a debug warning if it failed, before the final fail task.

MEDIUM roles/cloud-resources/tasks/digitalocean.yml (line ~107, ~148) - | unique filter lacks explanatory comment (confidence: 6/10)

The deduplication is non-obvious to future readers. Why would ['dblab', server_name | lower] ever have duplicates?

Suggestion: tags: "{{ ['dblab', server_name | lower] | unique }}" # unique prevents duplicate when server_name == 'dblab'

MEDIUM roles/cloud-resources/tasks/gcp.yml - Same | unique comment missing (confidence: 6/10)

Same as above for the GCP tags line.

Suggestion: items: "{{ ['dblab', server_name | lower] | unique }}" # unique prevents duplicate when server_name == 'dblab'

HIGH roles/cloud-resources/tasks/gcp.yml - server_result is undefined if rescue executes (confidence: 7/10)

If the rescue path runs, the instance task never completes so server_result is never registered. The ansible.builtin.fail at the end of rescue stops execution, which is the correct mitigation. However, if callers use ignore_errors or wrap this include in their own rescue, downstream tasks referencing server_result will fail with an undefined variable error.

Suggestion: This is adequately mitigated by the explicit fail in rescue. Low risk unless the include is wrapped in another rescue elsewhere.

MEDIUM roles/cloud-resources/tasks/digitalocean.yml - | unique not tested with mixed-case server_name (confidence: 7/10)

server_name=DBLAB or server_name=DbLab should deduplicate correctly (since | lower is applied first), but this case was not in the stated test plan.

Suggestion: Add a manual test step with server_name=DBLAB to confirm lowercasing + deduplication work correctly before merge.
