Step 7 listed a missing `ADMIN_GATE_SECRET` — a warning the container starts through — and said nothing about the three PayPal secrets, which are a hard error that crash-loops it. That is backwards: the secrets are the likeliest thing to be missing after a stack replacement, because Portainer stack variables belong to the stack and are discarded with it, and `DEMO_MODE` is false in production so the app refuses to start without them. Hit for real following the runbook.
The verify section now shows the actual log block, says what it means, and gives the way to tell a missing variable from a misnamed one: a hardcoded value cannot be missing, so its absence from the error list proves nothing, while an interpolated variable that stays quiet while others complain proves substitution works and those others are simply unset. That is the reading that turns the log into a diagnosis instead of a list.
It also says the loop is harmless while the values are fetched — the container refuses before it serves anything or touches data — and where the values live if the old stack is already gone, since the webhook id in particular is readable rather than only recreatable.
Step 2 now names every interpolated variable rather than describing them in general, and states the consequence of each class going missing. A general instruction to record the environment is easy to read as already done.
