Architecture

The execution boundary determines everything: features that need the system alive belong in the platform (OSS). Features that analyze artifacts after shutdown become the product (commercial). A framework for clean OSS/commercial separation.

Kubernetes Secrets are simple and often sufficient. But at scale, some teams separate compute from secret storage. Understanding the trade-offs: etcd vs cloud vaults, cluster RBAC vs cloud IAM, sync patterns vs runtime access, and when each pattern makes sense.

Three Rust error handling crates that seem to overlap but fill distinct roles. Learn when to use thiserror for typed errors, anyhow for application code, and error-envelope for HTTP boundaries.

JSON recreated XML’s entire ecosystem modularly. JSX brought back XML’s syntax. What does this teach us about technology evolution? Explore the architectural zeitgeist, pattern survival, and the modularity paradox: choice vs. discoverability.
