[v2] Zero-Copy Memory-Mapped Ring Buffer for State Rollback

[SHAURYASANYAL3]

Caution

ARE YOU SURE YOU WANT TO WORK ON THIS?
This issue is tagged as difficulty: extreme. It is designed specifically to test the absolute limits of systems engineering, mathematics, and low-level optimization.

• Expect no hand-holding. You will be dealing with undocumented OS behaviors, raw memory, or advanced math.
• Expect to fail. 99.9% of developers will not be able to solve this without introducing bloat or breaking the 0.1ms latency ceiling.
• Requirements: To claim this issue, you must reply with a highly detailed, technically rigorous execution plan. Do not just ask "Can I take this?". Prove you can take it by detailing the exact architectures, memory layouts, or mathematical proofs you intend to use. Vague plans will be immediately rejected.

Only proceed if you are absolutely confident in your ability to ship flawless, zero-bloat code.

The Problem:
If the agent triggers a Safety Block, we need to instantly roll back its execution state without pausing for heavy garbage collection, object instantiation, or deep copying.

The Task:
Implement a lock-free, zero-copy ring buffer using mmap. This must allow the State Lattice to instantly restore the agent's memory to a previous tick in <0.01ms by simply moving a pointer, completely avoiding the Python GIL and standard memory allocator.

Warning:
You will be bypassing Python's memory manager. Segmentation faults are guaranteed during development. Only claim this if you dream in pointers.
