It is not a log, not a callback, and not post-hoc auditing. It is a kernel-level atomic transaction that forces the decision, its reasoning, the PPP triplet, and the cryptographic signature to exist as a single unit or not at all.
Formal Definition
AtomicInferenceCapture(ctx, reasoning_trace, output, ppp_triplet, human_delta_chain) ≡ {
sign(BLAKE3(ctx ∥ reasoning_trace ∥ ppp_triplet ∥ human_delta_chain)),
persist(Merkle-append to forward-secret chain),
return committed
}
// Entire block executes as one indivisible kernel transaction
This entire block executes as one indivisible kernel transaction. There is no partial state visible to the system at any point.
Execution Flow (Step by Step)
1. Inference Entry
The model begins inference. The universal wrapper immediately triggers AKI.
2. Kernel Atomic Section Begins
local_irq_save(flags) disables all interrupts.preempt_disable() disables kernel preemption.
The CPU now runs in a protected, non-interruptible bubble.
3. Payload Assembly
The full payload is assembled in kernel memory:
• ctx (system context)
• reasoning_trace (structured JSON of every step)
• output (the raw AI result)
4. Cryptographic Operations
• BLAKE3 hash of the entire payload
• Ed25519 signature using kernel-held key
• Merkle tree append to the forward-secret chain
5. Commit or Rollback
If successful, the record is committed. If anything fails, the entire transaction rolls back; the record never exists.
6. Kernel Atomic Section Ends
Interrupts and preemption are restored.
Why This Is Mathematically Indivisible
Hardware-Level Critical Section
No other process, interrupt, or core can observe or modify the payload mid-operation.
CPU Primitive Enforcement
The CPU primitives create a true critical section at hardware level.
Instruction Ordering
Zero clocks or timers are used; atomicity is enforced by CPU instruction ordering.
Integration with PPP Triplet
The PPP triplet is not added afterward. It is part of the payload that is hashed and signed inside the atomic block. This guarantees that the meaning of each P is frozen at the exact inference instant.
Security and Evidentiary Properties
Tamper-Evident
Any post-facto change breaks the Merkle chain.
Non-Repudiable
Signed at the exact moment of thought.
Compromise-Resistant
Even if user-space is fully owned, the kernel still executes the capture.
Court-Ready
Meets and exceeds the Canada Evidence Act reliability test.
