Milestones

Milestone	What	Depends on
M0	Design v0 written. Done 2026-10-22.
M0.1	This design site, with the research list distributed to its pages and Sources and projects researched.
M0.5	Topology spike: a dummy file through GKE receiver → Tailscale → homelab → Parquet → Pages build. No real data, no gigabytes. Proves the encrypted hop, key handling, deletion, and build trigger.	A current homelab node, Tailscale, a GKE namespace
M1	Layer C live: Sources and projects, the first explainers, the methods page. Layer A spike: one hospital, ten codes, one procedure page rendered from a Parquet file. The costs site's generator decided.	M0.1
M2	Layer A for all seven hospitals and the full code list, with benchmarks, facility pages, the county overview, and the methods page. The yearly county table lands on the ledger's services page.	M1, research on facilities, codes, benchmark
M3	Layer D instructions page, consent text, and in-person intake; first submissions processed by hand.	M2, redaction research, counsel on HIPAA reading
M4	Homelab box online with storage; the receiver and the form open.	M0.5, hardware
M5	Layer B spike: one carrier, one network, Essex NPIs only, merged into the procedure pages.	M4, parser evaluation
M6	Layer B for all major carriers; the hospital-versus-insurer cross-check published.	M5
M7	A second county runs the pipeline from its own configuration.	M2 at least

The dates on the chart are durations for shape, not commitments. The one external gate is hardware for M4; everything before it runs on what exists.

Open

• When the homelab box is bought; its shape is on Homelab box, to be confirmed by the Layer B measurement.
