[Research/Ledger]: Implement Shared-Memory Atomic Token Accounting Ledger for Multi-Tenant Infrastructure Accounting

Problem

Stripe handles payment abstraction at Layer 7 using heavy HTTP rest database structures, which introduces high tracking latency. For high-throughput AI agent clusters executing millions of asynchronous inference routing pipelines per second, tracking token spending budgets and runtime computing capital allocation via standard database transactions causes instant pipeline choking and system serialization degradation.

Proposed Solution

Design a bare-metal, lock-free Autonomous Tokenomic Accounting Ledger Engine inside internal/storage/ledger.go driven natively by memory-mapped file descriptors (mmap) and hardware CPU atomic registers.

• Allocate a fixed, contiguous contiguous virtual memory block array that maps tenant budget allocations directly to host memory arrays.
• Execute sub-nanosecond ledger state modifications (credit deduction, allocation balances, payload volume verification) inside the critical networking hot loop utilizing low-overhead sync/atomic subtraction and addition primitives (atomic.AddInt64).
• Stream real-time transaction updates down to decentralized network cluster registries using persistent binary ring buffers, avoiding any filesystem or external database network round-trip overhead.

Alternatives

• Relying on external Redis or PostgreSQL transaction locks layers, which introduces a severe network latency bottleneck and fails under extreme multi-tenant scale.

Use Case

Transforms FaultPlane into an un-bypassable transaction engine for machine-to-machine micro-payments and computing resource allocation, routing and accounting traffic streams simultaneously with sub-microsecond line-rate performance.

Additional Notes

Must keep structural code boundaries completely isolated from standard high-level runtime storage engines.

Start by reading internal/storage/ledger.go and the repository's existing storage boundaries; no tests or concrete entry point are named in the issue. Before implementation, clarify the ledger's invariants, persistence and streaming requirements, and acceptance criteria; completion cannot be verified from the current description alone.
