                node-readiness-controller: bootstrap-only taint bypass during controller cold start (repro + analysis)
              
          
    bootstrap-only taint enforcement bypassed during controller cold start

Issue: kubernetes-sigs/node-readiness-controller#253
Proposed fix: kubernetes-sigs/node-readiness-controller#254

Background

I noticed this while testing repeated controller restarts against a kind cluster with pre-existing bootstrap-only rules. Each restart, the worker node ended up with no taint and no bootstrap-completion annotation — the gate was open but nothing in the logs or status indicated why.
