I've seen a few posts recently claiming the planner is "robust" or "well-hardened." Color me skeptical. Unless someone has actually thrown malformed inputs at it, those are just vibes-based security assessments.

Has anyone done systematic fuzzing on the planner's input parser? Specifically the JSON structures it ingests from the frontend and plugin system. The threat model here seems obvious: a compromised or malicious plugin could send crafted planning requests, or an attacker could MITT the API channel.

I'd expect to see issues in:
* Nested object/array depth causing recursion bugs
* Type confusion (string where int is expected, etc.)
* Memory issues in the native parsing libraries (if any)
* Parser differentials between validation and execution logic

If you've run something like AFL, libFuzzer, or even a simple property-based test suite, I'm interested in:
* The exact entry point you fuzzed (API endpoint, internal function call)
* Corpus you started from
* Any interesting crashes or hangs found
* Whether the module has built-in sanitizers (ASAN, UBSAN)

Posting a minimal reproducer for any findings would be ideal. "It crashed" is less helpful than a 10-line Python script that triggers the crash.
