Complete the Electron replacement boundary before merging by removing the renderer-side Tauri host fallback, tightening H5/browser access so only desktop navigation is tokenless, and moving desktop release publication to a tag-driven GitHub Actions matrix with a single final publish job.
Constraint: H5/browser capability access must not gain tokenless access through localhost or retired Tauri origins
Constraint: Desktop release artifacts must be built by GitHub Actions from version tags, not treated as local build outputs
Rejected: Keep localhost browser origins trusted for convenience | local browser contexts can access loopback services and must use the H5 token path
Rejected: Publish from each matrix job | partial releases can be created before all platforms finish
Confidence: high
Scope-risk: broad
Directive: Do not reintroduce Tauri origins or localhost browser origins into the trusted desktop origin set without a reviewed security design

The desktop docs now explain the intended H5 setup path for personal and team use: enable H5 in Settings, generate a one-time token, configure allowed origins, and use LAN or a reverse proxy to open the mobile browser chat surface.
Constraint: H5 is opt-in browser access, not a public multi-tenant auth system.
Rejected: Hide the setup details in the implementation spec only | users need operational guidance for token handling, CORS, and reverse proxy routing.
Confidence: high
Scope-risk: narrow
Directive: Keep this page aligned with Settings labels and the token/CORS behavior before documenting broader public hosting.
Tested: bun run check:docs
Tested: Live local smoke with temporary HOME: /health 200, H5 verify without token 401, H5 verify with token 200, configured Origin echoed by CORS.
