Wiki — radience

How does a digital twin couple laser-plasma physics, Monte Carlo dose, regulatory constraints, and clinical practice into one verifiable system ?

This wiki holds the connective tissue. Wikipedia owns the components — what an electron is, what a regulation says, what a Monte Carlo method does. The radience wiki owns the couplings: how a laser-plasma electron source becomes a clinical dose, how an EU regulation reaches into a Rust crate, how a 40 Gy/s pulse becomes a biological signal. Every page either justifies its existence by an absence on en.wp/fr.wp, or by a radience-specific weighting the public encyclopedia cannot provide.

Tour-0 is on the wall. Some pages are stubs. Every page has an ## Open questions section. Silence is forbidden.

Folders reserved for later Tours — not yet on disk : 00-foundations/, 25-numerical-rigor/, 50-cliniciens/, 70-radience-context/, 99-bibliography/. They will land as soon as a coupling makes them load-bearing.

Tour cadence

Tour-0 — 2026-05-26 (today). Degraded gates, debt logged in changelog/2026-05-26-tour-0.md.
Monday Tour — first Monday Tour: 2026-06-01. Weekly thereafter. Every Tour ships one paragraph in changelog/YYYY-MM-DD.md even if no page is promoted.

How to read

The door (this index) is for the first-arriving reader. The audience target is a senior VHEE physicist arriving on 2026-09-01 who should reach the working edge in two reading days, without a Slack message.
Each page declares its addresses_reader in the frontmatter. Some pages are addressed to cofounders, some to the public, some to the grant team. The frontmatter tells you whom the page is for.
Every page has an ## Open questions section. Read it. The questions are the wiki's living edge.

Open questions

Is the load-bearing question above (the wiki's reason to exist) still the right one after Tour-1 ? Re-audit when the first SFRT / VHEE coupling page lands.
The ten-folder layout is the synthesis recommendation ; will any folder remain empty after three Tours ? If so, fold or rename.
The audience target (a senior VHEE physicist arriving 2026-09-01 reaching the working edge in two reading days, without a Slack message) is the godin primary circle. Should an explicit second audience surface be split out, or is one door enough ?
(empty-marked, Tour-0) — When does the wiki acquire a search index / full-text browse ? — deferred until the build pipeline (C8) lands.
