📝 WalkthroughWalkthroughThe runtime-required documentation now states that existing NodeWright annotations prevent automatic re-tainting. It covers behavior after another NodeWright processes a node and after Estimated code review effort: 1 (Trivial) | ~2 minutes Mergeability Score: 🟡 Moderate · up to The recovery documentation can make package pods unschedulable under custom taint configuration and can unintentionally reset multiple nodes or remove state owned by other NodeWrights; these instructions should be corrected before merging. A required source-file license header also remains unresolved. Suggested labels: Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 1❌ Failed checks (1 warning)

- Around line 3141-3168: Add a getAutoTaintNodes test covering two NodeWrights
selecting the same node: configure the first sorted NodeWright with matching
nodeState_ state and the second without state, then assert exactly one
auto-taint candidate. Use the existing BuildState, autoTaintSkyhook, and
nodeWithAnnotations helpers to exercise the moved seen assignment and preserve
cross-NodeWright selection behavior.

…nd is one-way "A node is considered new if it has no NodeWright annotations" is precise but easy to read as "new to this NodeWright". It is not: the check is for any nodewright.nvidia.com/* annotation, so once any NodeWright has touched a node, auto-taint never treats it as new again. Two consequences were undocumented and surprise people: - a different NodeWright selecting the node for the first time does not auto-taint it, because the node is not new - `kubectl nodewright reset` does not re-gate a node: it clears package state so packages re-run, but the node keeps its other annotations (including the node-scoped autoTaint_ marker), so the packages re-run untainted Document both, show how to re-apply the taint explicitly when that is what you want, and state that returning a node to "new" is a deliberate human action. Reinforce that pre-tainting at provisioning is the reliable gate; autoTaintNewNodes gates nodes arriving in the cluster and is not a general re-gating mechanism. No behavior change. Refs #457

In `@docs/runtime_required.md`:
- Around line 83-90: Update the runtime-required recovery commands to use the
configured runtimeRequiredTaint value rather than a hard-coded taint, and scope
reset to the selected node with kubectl nodewright node reset <node>
--nodewright <nodewright-name> --confirm. Ensure cleanup removes only the
relevant autoTaint_ marker; do not recommend removing all NodeWright
annotations, since other NodeWrights may own them.

Summary
Docs-only. No behavior change, and no code change: the diff is 28 added lines in
docs/runtime_required.md.Supersedes the original intent of this PR. See #457 for why that turned out not to be a bug.
What this clarifies
docs/runtime_required.mdsaid:That is accurate but easy to read as "new to this NodeWright". It is not. The check is for any
nodewright.nvidia.com/*annotation, so once any NodeWright has touched a node, auto-taint never treats it as new again.Two consequences were undocumented:
kubectl nodewright resetdoes not re-gate a node. Reset clears package state so packages re-run, but the node keeps its other annotations, including the node-scopedautoTaint_<taintKey>marker. So the packages re-run without the runtime-required taint.The second is the one worth writing down: reset is not a way to re-gate a node, and reading the old wording as per-NodeWright leads you to assume it is.
What was added
