Verification Criteria That Derive From Requirements (Not Invented Next to Them)
8 minChange a rule on an Event Modeling board and watch a previously-passing build fail — with zero code changes. The one-way path from a spec artefact to acceptance criteria, an oracle gate, and drift detection.
Pi vs. Antigravity vs. Orca: One Job Per Harness, Not One Harness to Rule Them
7 minWhy I retired Orca, kept Antigravity for exactly one job, and picked Pi as the headless runner underneath an oracle-gated build pipeline — and the measured result: Pi came in 27–55× cheaper than Claude Code per successful build on the same tasks.
When Your Governance Layer Is the Thing That's Wrong
6 minAn autonomous coding agent solved a HIPAA-shaped PHI anonymizer correctly on its first live attempt — and a deterministic harness failed it five times anyway, because the wrong file was under scrutiny.
The Orca Agent Development Environment: A Practitioner's Guide
6 minA practitioner's field guide to Orca, an open-source multi-agent development environment — what the fan-out pattern actually buys you, and where git worktree isolation quietly breaks down.
Cybersecurity Assessment: Gunra Ransomware (AA26-222A)
3 minA practical breakdown of CISA advisory AA26-222A on the Gunra ransomware-as-a-service operation — attack vectors, and prioritized mitigations for edge devices, identity, and lateral movement.
Converting Event Modelling Board to GitHub Specs
2 minA six-step pipeline for turning an Event Modeling board into GitHub Spec-Kit specs, keeping the architectural constitution separate from fast-changing feature slices.
