❝ See wrong code, fix it on the spot — no switching out to open an IDE. ❞

pi-web file editor extension (extensible editor architecture):

• fileViewer slot take over: text-like files are rendered by the extension component (Monaco editing); non-text goes to the core's legacy viewer
• Unified image preview hosting (2026-09-17): images popped from the message list/input box/markdown (base64/API URLs, no disk path) share the same full-featured viewer with on-disk image files (zoom · pinch · pan · rotate · info panel · copy · download). The host invokes it via __aitiEditor.openImagePreview(src,{alt}) (the host side has no image container/image tab; lazy extensions are materialized idempotently by the entry bridge); the extension presents it as a floating window — dialogs slot + aiti-float contract (drag / small-screen fullscreen); without aiti-float installed, its own fixed positioning serves as the fallback; when the extension is unavailable on the host side it falls back to the upstream native lightbox. On small screens the toolbar wraps with bounded width and no overflow; the checkerboard background follows the host theme.
• Save: POST /save fs write + baseMtime conflict detection (409) + whitelist/size checks
• Read/watch: goes through its own ticketed endpoints (paths never appear in URLs, preventing access-log leaks) — POST /ticket (TTL 1h sliding renewal) exchanges for a ticket → /t/<ticket>/raw|stat|file (provider delegation + Range streaming); watch is its own fs.watch (300ms debounce) → pushed via the event-bus topic ed-watch, auto-stops after 30min idle
• Archive extraction: 7-Zip chain — use the system install when present; otherwise justget races multiple sources to download a portable 7za, cached locally
• Delivered (formerly the M2+ roadmap): the window.__aitiEditor registry is open; file provider registration (registerFileProvider + /file delegation); Markdown smart preview (editor.mdPreviewSmart); TS sibling-file extraLib (/ts-siblings)
• Document preview: ticketed /preview (CSP sandbox + opaque origin + noscript=1 can strip author scripts); soffice-to-PDF conversion (doc-pdf, feature soffice.path); convert to an editable format and save-as (POST /convert-saveas: .doc→.docx / .ppt→.pptx); AI self-management skill install-soffice
• Editor surroundings: file rename/move (/rename /move); unsaved edit cache (cache-write/read/delete, survives reopen); git change markers (git-changes/git-base); session-files session file aggregation; GET/PUT /prefs preferences (editor-prefs.json covered by the aiti-configs backup)

Depends on js-yaml / sql-formatter / tar-stream / yauzl / exifr / @aiti-ai/ext-shared.
