PersistentPreRun and PersistentPostRun hooks do not cascade hierarchically; intermediate and leaf definitions shadow ancestor hooks entirely, executing only the nearest hook.

Defining PersistentPreRun on a subcommand or group executes in addition to ancestor PersistentPreRun hooks in hierarchical root-to-leaf order.

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

PersistentPreRun on a subcommand or group completely shadows ancestor PersistentPreRun hooks, executing only the nearest hook and skipping root initialization unless manually chained.
A subcommand defining only PreRun executes the nearest ancestor PersistentPreRun first followed by its own PreRun.
When a single command defines both PersistentPreRun and PreRun, PersistentPreRun executes first followed by PreRun before Run.
When both error-returning (*E) and non-error variants are set on the same hook, Cobra executes the *E variant and silently ignores the non-E function.
Returning an error from PersistentPreRunE or PreRunE immediately short-circuits execution, skipping Run, PostRun, and PersistentPostRun.
Returning an error from RunE aborts before PostRun and PersistentPostRun execute, returning the error to Execute.
Context mutations performed via cmd.SetContext in PersistentPreRun or PreRun are preserved and accessible via cmd.Context in Run and PostRun hooks.
PostRun executes on the active command before the nearest PersistentPostRun, which is similarly shadowed by intermediate definitions.
