First advanced-chat tier, a bounded delta onto the Chats core's named seams. lib/attachment-store.ts keeps sent attachment bytes in IndexedDB (bounded to the last 20 sends) so attachments survive refreshes; the hook merges them back on transcript rehydrate. The composer gains the attachment pill and picker with paste/drop; HEIC and oversized images re-encode through a canvas before send. Message bubbles render attachment chips and dedupe produced-file chips off the daemon's real Write arg key via lib/file-meta (which reaches its final exported state here); file-preview.tsx renders image and PDF previews; chat-view hosts the attachment side panel with the object-URL lifecycle.

Stack 13/21 — Studio: chat attachments, produced files, previews
First advanced-chat tier — a bounded delta onto PR 7's named seams.
lib/attachment-store.ts— IndexedDB store for sent attachment bytes (20-send bound), so attachments survive refreshes;sentAttachmentsRefmerges them back on transcript rehydrate.file-preview.tsx(+test) — image/PDF previews (the PDF iframe arm + the canvas crash fix).message-bubble: AttachmentChip + produced-file chips read the daemon's real Write arg key and dedupe vialib/file-meta(from PR 4) — files a chat writes render as openable attachments.chat-view: the AttachmentPanel arm + object-URL lifecycle.~5 bounded chunks in the core chat files, matching the shape of the original commits. Core flows untouched — the e2e specs are structurally unaffected.
Demo at this stack point: paste an image into a chat, preview produced files and PDFs, refresh mid-conversation and keep your attachments.
Part of the stacked landing of #618.
