What the system is, in ten minutes. The six substrates, the L0 / L1 / L2 stack, the data flow on every upload, the voice discipline.docs/architecture.md
Coverage of common operations, response-time tables, "who hits what" attribution, the golden-path smoke harness, the regression alarms that block ship.docs/PIPELINE-METRICS.md
How Etsy's per-token bucket and eBay's per-application pool fit under one unified budget facade. Fair-share partitioning, burn-rate alerts, the policy field shown to operators.docs/STORES-SCALING.md
Parent canon for the bare Lacuna mark. Living Mark Mode supported — bar segments map to telemetry channels via ANSI 24-bit color escape sequences.research/lacuna-did-v1.md
The dynamical-systems analysis behind Loam — the closed loop that turns usage into a graph that answers the next question for free. The engineering manual ships as PDF; this is the analysis it leans on.research/loam-bifurcation-analysis-v0.1.md
Patent surfaces, trademark posture, copyright register. What is claimed, what is deliberately left open, and the dates on each filing.research/ip-filings-v0.1.md
