Loosen the step limits, which I sized too tightly - #81

Conversation
The limits added yesterday were taken from one run's medians, and two of them were below what the suite normally does. `Seed every app's config and secrets` got four minutes and then timed out, failing #77, a pull request that changes nothing but a comment in renovate.json5. Resized from seventeen samples across every recent passing run, at four to six times the worst case rather than a small multiple of the median: step worst was now Set up rootless Podman 283s 6 10 Wait for containers 179s 5 7 Seed configs 82s 4 8 Run integration tests 279s 9 12 Pull container images 73s 6 12 Start stack 101s 5 10 Wire connections 71s 4 10 Install xmlstarlet 70s 3 5 Most are back to what they were before I touched them, which is the honest outcome: those values already accounted for a variance that a single run does not show. What the change was actually for survives. Every step is still bounded, where before four of them were not, and `Install xmlstarlet` still retries. That is what stops a hung apt spending the whole budget. A step limit is there to catch a step that has hung, not to police how slow a busy runner is, and sizing them near the observed maximum inverts that.

| # 20, from the steps of passing runs summing to about 15 minutes. An earlier | ||
| # comment here claimed two thirds of headroom, taken from run level | ||
| # timestamps reading 11 or 12; the steps are the honest measure and this is | ||
| # nearer a third. It should not come down without shortening the suite. | ||
| # | ||
| # This stays the binding limit, and the per-step limits below are not trying | ||
| # to replace it. They sum past an hour because each allows for its own worst | ||
| # case. What they buy is that a single stalled step dies in two or three | ||
| # minutes instead of spending the whole budget, which is exactly what | ||
| # `apt-get update` did twice on #68, hanging the full twenty while every | ||
| # later step was skipped. Nothing in the suite job is unbounded now. | ||
| # This stays the binding limit and the per-step limits below do not try to | ||

| # *hung*, not to police normal variance. | ||
| # | ||
| # Sized at four to six times the worst of seventeen samples, or whatever the | ||
| # value was before, whichever is higher. A first attempt sized them from a | ||

| # runs more often than it catches real hangs. |

Update the remaining 25-minute references.
The binding job limit is 20 minutes at Line 263. The comments above Pull container images and Start stack still describe a 25-minute limit at Lines 560-561 and 586-590. Update those comments to 20 minutes so timeout diagnostics match the active policy.

The limits added in #74 came from one run's medians, and two were below what the suite normally does.
Seed every app's config and secretsgot four minutes, then timed out and failed #77, a pull request that changes nothing but a comment inrenovate.json5.Resized from 17 samples, not one
Across every recent passing run:
Most land back on the values they had before #74, which is the honest outcome: those numbers already accounted for a variance a single run does not reveal. Note that
Seedtimed out at 240s despite a worst observed of 82s, so a busy runner can be three times slower than anything in the sample.What #74 was actually for still stands
Every step is bounded, where four were not before, and
Install xmlstarletstill retries with explicit apt timeouts. That is what stops a hungapt-get updatespending the entire job budget, which is the incident that started this.The principle I got wrong, now written in the file: a step limit exists to catch a step that has hung, not to police how slow a busy runner is. Sizing them near the observed maximum fails honest runs more often than it catches real hangs.
Blocking
#77 cannot pass until this merges.
