AWS mediatailor documentation change

Service: mediatailor · 2026-05-07 · Documentation low

File: mediatailor/latest/ug/log-types.md

Summary

Added new log types for pre-session initialization hooks including function completion, errors, and summary events. Extended log properties with execution metadata fields.

Security assessment

New logs improve operational visibility but don't address specific security vulnerabilities or describe security features. Primarily aids debugging and monitoring of hook executions without security context.
