Host-release 2020 VIPM lifecycle drill evidence (policy-source lane, no #498 bridge):

• Attempt 1 (expected policy gate failure path):
  • run_id: 22514621132
  • run_url: https://github.com/LabVIEW-Community-CI-CD/labview-cdev-surface/actions/runs/22514621132
  • top-level report: not generated (execution skipped after preflight gate)
  • machine preflight status: ailed
  • machine preflight reason:
    unner_account_unsupported (NT AUTHORITY\SYSTEM with �llow_system_account=false)
• Attempt 2 (single deterministic retry with �llow_system_account=true):
  • run_id: 22514638435
  • run_url: https://github.com/LabVIEW-Community-CI-CD/labview-cdev-surface/actions/runs/22514638435
  • execution status: ailure
  • drill reason_code (from runtime log): iteration_failed
  • failure evidence: Smoke installer failed with exit code 1; missing iteration-summary.json
  • artifact upload step also failed with transient transport error: ECONNRESET
    Expected pass reason codes (�ip_lifecycle_drill_passed / �ip_lifecycle_passed) were not reached in this deterministic run pair.
    Scope note: this drill validates the existing policy-source pin behavior only; it does not validate merged
    i/labview-icon-editor#498 content.

Deterministic next-action update (after failure-path hardening):

• Branch head: �8ff92af79a69ca9c3bd73b765da25caab5d31e7
• Latest diagnostic run: 22515020969
• URL: https://github.com/LabVIEW-Community-CI-CD/labview-cdev-surface/actions/runs/22515020969
  What changed before this run:
• ensured iteration-summary.json is always emitted on failure
• added deterministic artifact bundle + retry upload path
• captured full runner-cli stderr stream into workspace-installer-ppl-64-runner-cli.log
  Observed deterministic failure (still blocking pass):
• top-level: status=fail,
  eason_code=ppl_gate_failed
• root cause from captured runner-cli log:
  • LabVIEWCLI ExecuteBuildSpec failed with exit code 2
  • broken VIs during PPL build include:
    • FakedArray.lvclass:Process Template Graphics.vi
    • Tools Paint.lvclass:Fill.vi
  • error detail includes Hidden front panel control has undefined type
    Evidence file in artifact bundle:
• dev-smoke-lvie-2020/labview-icon-editor/builds/status/workspace-installer-ppl-64-runner-cli.log
  Scope note: this remains policy-source validation lane (no #498 bridge pin change).
