Living handoffs
Lane continuity survives long work sessions and compaction boundaries. The next reviewer inherits state, not folklore.
Architecture case
DNA Health Insights proves the pattern under pressure.
The reference project required multi-agent orchestration, evidence-backed browser UAT, legal-copy hardening, sensitive-data handling rules, and source-controlled validation. The public account that follows is intentionally redacted — what survives is the pattern.

Orchestration pattern
Pattern
Evidence before authority.
The system is valuable because every handoff, claim, screenshot, and review can be inspected by another team. The model is never treated as the only witness, and no step advances without a documented gate behind it.
Each lane terminates in a release gate. Gates are fail-closed by default. A gate that lacks evidence holds the work; it does not promote it on the model's say-so.
Privacy & telemetry posture
Sensitive data is treated structurally, not editorially.
Privacy is enforced by the architecture, not by promises in the copy. Below is the public-summary view: what we count, how we mask, and what we refuse to publish without formal review.

Pattern outcomes
Browser-rendered UAT
Pages are tested as users see them — not as source code claims. Screenshots are first-class evidence, not slide filler.
Claim hardening
Public copy avoids unverified legal, privacy, and security promises. Words that cannot be defended in audit do not ship.
