Persist orchestration and payment events for audit history

[Flamki]

Problem

Events currently live in memory/logs only; durable history is needed for debugging and demos.

Scope

• Add storage adapter (file or lightweight DB) for run history
• Persist key event metadata (task, spend, tx hash, status)
• Add API to fetch recent runs

Acceptance Criteria

• Historical runs survive process restart
• Audit records include spend + tx proof linkage
• Storage strategy is documented and configurable

I’d like to work on this issue because durable event persistence and audit history are important for observability, debugging, operational transparency, and demonstrating reliable orchestration workflows. I have experience building backend persistence layers, event tracking systems, and lightweight audit pipelines using configurable storage approaches and clean API design. For this task, I would implement a storage adapter for persisting orchestration and payment event history, ensure key metadata such as task details, spend information, transaction hashes, and status changes are stored reliably across restarts, add an API for querying recent runs, and document the storage strategy clearly so it remains configurable and maintainable for different deployment environments.
