Agent layer: /.well-known/agent.json and Markdown twins of the public pages (#128)

OP OpenVibers committed 15 days ago · 893021b2cf · 9 files, +408 −9

openvibe-shared v4.34.0 (was v4.33.0). server/agent-descriptor.js describes what openvibe.watch
really serves: the bearer-token API at /api/v1, the pages that explain how a watch works, llms.txt
and the sitemap. server/agent-pages.js renders the twins of /, /how-it-works and /updates through
the site own page router, driven by a request without a session, so a twin is the page own render
signed out - the same builders, the same data, no personalisation. The layer is mounted in
server/app.js before the page routes but gated to twin requests only (a .md path, ?format=markdown
or an explicit text/markdown Accept) plus /.well-known/agent.json matched exactly, so a browser
keeps the page own render and /.well-known/security.txt is untouched. The head names the twin
(openvibe-shared/shell agentLayer), and deploy/nginx gets the two GET-only locations the vhost
needs: without them its deny-all rule for dotted paths would refuse every .md twin.
