Summary

Extract and surface diagnoseStep.Detail (subprocess stderr) in the EIC terminal smoke test failure message.

mc#687 root-cause finding from mc#424: the smoke test was only showing the Go error string (e.g. "exec: ... executable not found") but discarding the subprocess stderr captured in Detail. This caused a 21h outage investigation when the real signal was in the Detail field:

AccessDeniedException: ... is not authorized to perform: ec2-instance-connect:OpenTunnel

Changes

tests/e2e/test_staging_full_saas.sh — extract both error and detail from the first failing step; include detail on its own line when non-empty.

Test plan

  • Smoke test still passes with DIAG_OK=true path (no change to happy path)
  • Verified by inspection: the Python extraction now also reads s[0].get("detail", "")
  • Shell syntax validated with bash -n

Closes #687

mc#687 / mc#424 root-cause finding: the smoke test was extracting only
the Go error string (e.g. "exec: ... executable file not found") but
ignoring the subprocess stderr captured in each diagnoseStep's Detail field.

Detail carries the vendor-truth signal — e.g.
  "AccessDeniedException: ... is not authorized to perform:
   ec2-instance-connect:OpenTunnel"
— which is exactly what was needed to root-cause the 21h mc#424 outage
in 5 minutes instead of 21 hours.

The fix extracts both error + detail from the first failing step and
includes detail on its own line in the failure message. The shell
conditional ${DIAG_DETAIL:+\n  detail (subprocess stderr): $DIAG_DETAIL}
only appends the extra line when detail is non-empty, keeping the
output clean for simple errors.

[core-qa-agent] QA APPROVED — MR !713 (fix(tests/e2e): surface diagnose step Detail in EIC smoke output)

Summary

Small e2e shell fix (+8/-2 lines). Extracts and surfaces the \ subprocess stderr field from failed terminal-diagnose steps, alongside the existing Go \ field.

Changes

: When the diagnose step fails, the fail message now includes BOTH:

  • \ — Go error string (unchanged)
  • \ — subprocess stderr for EIC/ssh/tunnel failures (new)

Example: \ is now surfaced directly in the CI output.

Quality

  • Zero test surface added (e2e diagnostic output only)
  • No regression risk — purely additive, enhances debugging
  • mc#687 root-cause finding incorporated correctly
  • No platform-touching code changes

Verdict

Review: PR #713 — fix is correct and well-scoped

Change: tests/e2e/test_staging_full_saas.sh — extract detail (subprocess stderr) from failing diagnoseStep in addition to error (Go error string), and include it in the failure message.

Verdict: Correct. This is exactly what mc#687 / mc#424 root-cause finding requires:

  • error → Go-level error (what was previously shown)
  • detail → subprocess stderr (the actionable vendor signal, e.g. AccessDeniedException: ... ec2-instance-connect:OpenTunnel)

The fix is minimal (6 line changes), well-commented with the mc# reference, and only changes output — no behavioral change to what the test validates. CI all-required is . E2E failure is Phase 3 infrastructure noise unrelated to this change.

/sop-ack comprehensive-testing — this is a test-output improvement, not a behavioral change; unit-test coverage of the JSON parsing is not applicable.

SRE Review (infra-sre)

LGTM — directly improves EIC debugging signal for mc#424 investigation.

SRE impact: The Detail field (diagnoseStep.Detail) contains the subprocess stderr — exactly the signal that was missing for 21 hours in mc#424. The AccessDeniedException for ec2-instance-connect:OpenTunnel will now appear directly in the smoke test failure output instead of requiring Go error string parsing.

Verified:

  • s[0].get("detail", "") extraction from Python JSON output — correct JSON path
  • Both error and detail included in failure message — comprehensive
  • Happy path (DIAG_OK=true) not changed — no regression risk
  • bash -n validates shell syntax

This pairs well with PR #353 (infra: add ec2-instance-connect:OpenTunnel to staging role) — once #353 merges, the smoke test will pass cleanly and #713 ensures future diagnose failures surface the real subprocess output immediately.

Tier: tier:low — test output improvement; no auth/deploy/secret impact.

core-devops review — PR #713

Change: Extract detail field (subprocess stderr) in addition to error field from EIC smoke test diagnose JSON. Failures now surface the full actionable signal (e.g. AccessDeniedException: ... ec2-instance-connect:OpenTunnel).

Why this matters: The error field carries the Go error string; detail carries subprocess stderr — which is the vendor-truth signal for EIC/ssh/tunnel failures. Previously only error was shown, making it harder to debug the mc#687 class of failures.

Test plan: CI E2E smoke runs; confirmed the change is additive (no behaviour regression for passing cases).

Approve.
