Runtime engineering case study
Building Nikxius Runtime: Execution Control and Recovery
How I built Nikxius Runtime: exact-action authorization, Kubernetes rollback, recovery after lost replies, portable evidence, and design-partner onboarding.
Field notes from real systems
Engineering case studies with the receipts left in.
Architecture, constraints, verification, and failure modes from building agent memory, graph retrieval, closed-loop engineering systems, and execution control and recovery for production automation.
Production system case study
How I Built Shared Memory for Claude Code and Codex
A technical case study of a tenant-scoped memory system that lets Claude Code and Codex share verified engineering context without storing raw transcripts.
System design case study
From 20 Agent Loops to One Guarded PR
A repository-backed case study in designing a 17-agent engineering system, then cutting the MVP to one bounded, testable pull-request loop.
Retrieval engineering case study
A Graph You Can Audit: Provenance-First Agent Memory
A technical case study of combining deterministic search, local embeddings, and provenance-derived graph relations for tenant-scoped agent memory.
