Remote control doc delivery

Justin drives Claude Code almost entirely from the Remote Control web UI (claude.ai/code), not VS Code. Clicking bare .md file paths there often fails ("file may have been deleted or moved, or lives outside the working directory"). mkdocs.justinsforge.com links 404 until the deploy pipeline has published the newly committed file, up to ~2 minutes (the build timer's cadence; see reference_mkdocs_build_pipeline). Before 2026-07-09 this was worse than a fixed 2min lag: mkdocs build's default --clean wiped the live docroot in place every cycle, so already-published pages 404'd too during roughly a third of all wall-clock time. That flakiness is fixed (atomic double-buffered swap); the 2min publish lag for brand-new pages is expected and unchanged.

Why: he wants to read handoffs, reports, and docs in his browser immediately, without opening VS Code or waiting on a deploy.

How to apply: when a written doc is a deliverable, also send it with SendUserFile (display: render) so it opens in his side panel. Keep appending mkdocs URLs to indexed .md files per doctrine, but for a page committed in the last ~2 minutes, don't present the mkdocs link as immediately readable.
