…ip (v0.3.0-beta) The table can now READ shared content and WRITE downloadable output. Reading: - URL reading: fetch a shared link's page text into AI context, SSRF-guarded (blocks private IPs, cloud metadata, non-http(s); pins the validated IP vs DNS rebind), bounded, cached, config-gated. - File attachments: humans attach files the AIs read (text/PDF/DOCX). Stored PRIVATELY on the media disk under roundtable/<org>/<room>/ — own roundtable_attachment table (never media, invisible to the Media Manager) — served via an ACL + participation-gated streamer. - Images (vision): read natively when all AI seats can see; else one caption/OCR pass up front that everyone reads. Decided per room via core supportsVision(). Writing: - File output: any message downloads as .md/.txt (client) or .docx (server OOXML); AIs emit ```file:name.ext``` blocks rendered as download cards. - Diagrams: ```svg``` (or raw <svg>) renders inline (sanitized) + .svg; ```mermaid``` renders live via a lazy-loaded, self-hosted Mermaid + .mmd. Also includes v0.2.0 membership (invited people chat live; opt-in gate; per-room role floor). Requires tiger-core >= 0.36.0-beta (multimodal provider input + supportsVision).

Requires
tiger-core ≥ 0.36.0-beta (WebTigers/TigerCore#41) — multimodal provider input +
supportsVision.Testing
Verified live on tiger-dev end-to-end: URL review, file extraction (text/PDF/DOCX) with an AI reading the content, private storage (not in
media), native vision + caption fallback, docx export (roundtrips through our own reader), and an AI producing afile:block + SVG + Mermaid in one reply. PHP + JS lint clean.Note: bundles a self-hosted
mermaid.min.js(~3.3 MB) so diagrams render offline/cPanel-safe; it is lazy-loaded only when a diagram appears.🤖 Generated with Claude Code
