OMP independently auto-discovers project or user `APPEND_SYSTEM.md` whenever that flag is absent, and `--no-rules` does not disable that path, so running this hook in a repository containing such a file silently appends repository-controlled instructions at system-prompt priority and defeats the claimed isolated policy boundary. Pass an explicit empty append-system-prompt value (and assert the flag/value in the focused test), or otherwise disable that discovery source.",

It also interpolates unbounded, unescaped `id` and `session_id` values: an ID containing `--><project-context>...</project-context><!--` injects extra accepted stdout while the command exits successfully, and a large ID bypasses the 48 KiB output cap. Return only the two empty blocks on stdout (put identifiers on stderr if needed) and route this path through the same size/shape validator before success.",
