2026-10-02 · Lab 01 — Terraform 1.16, before and after

• Four experiments run on Terraform 1.14.5 and 1.16.4, local providers only.
• Finding: with the default on_failure = halt, a failed post-create check stops one apply; the next apply builds the dependent resource without checking again. taint keeps it blocked.
• Finding: deleting a resource block removes its destroy = false protection; use a removed block.
• Guided course: learn/LEARN.md, four lessons, predict → run → explain.
