Cost Analyzer: Automated Account Reconciliation

The Cost Analyzer turns Frao's raw invoices, receipts, and statements into a classified, deduplicated, hash-chained ledger — then reconciles the on-chain wallet against it. A look at the pipeline, the storage taxonomy, and the data-integrity decisions baked into the books.

COSAW Under the Hood: frao-cosaw-mcp and the Phase-Orchestrator

The reference companion to Everything Is a Prompt. Every mode of frao-cosaw-mcp, the message bus, the context monitor, the phase-orchestrator launch modes, the Docker wiring, and the exact self-injection sequence.

Everything Is a Prompt: Context Engineering with COSAW

A model's output quality is set by the context it reasons over, not the wording of the prompt. How Frao engineers that context with COSAW — analysis, architecture, and implementation plan in stages, each phase launched as a dedicated, isolated, containerized agent.

Under the Hood: Frao's Self-Hosted Authoritative DNS Stack

The technical companion: five components, two namespaces (public vs. internal split-horizon), one writer, two nameservers in two locations. Architecture, configuration samples, measured change latency, security, and how we verified the cutover.

Owning Our Address on the Internet: Frao Runs Its Own DNS

This week, frao.tech began to be served by nameservers we own and operate ourselves — two independent hosts, two locations, one platform we control end to end. What the milestone means, what it gives us, and what it asks of us.

Emergent Failure: A Postmortem of the 2026-07-31 Global OOM Cascade

On 2026-07-31, a global out-of-memory cascade froze the primary host twice. Root cause: a fallback price with no authority signal, a risk engine with no dedupe, and a container with no memory ceiling. A case study in how complex systems fail at the seams.
