…elpers Both istiocsr and trustmanager controllers stored a context.Context field on their Reconciler struct, initialized once in New(). The Reconcile() method receives a request-scoped context from controller-runtime but all helper methods used the stale struct field instead. This defeats cancellation and deadline propagation from the framework. Remove the ctx field from both Reconciler structs and thread the context parameter from Reconcile() through every helper method call chain.

Summary
ctx context.Contextfield from bothistiocsrandtrustmanagerReconciler structsReconcile(ctx context.Context, ...)through every helper method call chain (37 files, ~90 call sites)context.Background()explicitly (semantically correct for test entrypoints)Motivation
Both controllers stored a
context.Contextinitialized once tocontext.Background()inNew(). TheReconcile()method receives a proper request-scoped context from controller-runtime, but all helper methods used the stale struct field. This defeats cancellation and deadline propagation from the framework.This supersedes #242, which attempted to standardize context usage by replacing
context.Background()withcontext.TODO()everywhere — semantically backwards sincecontext.TODO()signals "placeholder, haven't decided yet" whilecontext.Background()is correct for top-level contexts.Test plan
