Unified Web @file and @session source. The browser starts the fileReferences/list and sessionReferenceResolver/candidates Remote calls together for an unquoted token, deterministically orders files before sessions with locale-registered folder/file/session labels, and renders the rows under non-selectable file and session section headings without a redundant raw reference source title. Either failed candidate domain degrades independently. An open @"… token searches files only.

File picks preserve the natural text defined by the shared @path grammar as their hidden serialized and clipboard form. A file closes completion as an atomic inline reference displayed with a file glyph, business-color filename, and no capsule. A directory remains plain editable path text with a folder glyph and keeps the menu active at its trailing slash so the user can descend another level. Paths containing whitespace use @"path with spaces", and a quote the user opened explicitly remains quoted.

Session picks insert an atomic inline reference whose hidden ref and clipboard representation are the canonical @[label](https://github.com/fufankeji/deepseek-harness-studio/blob/257d429156a243517a2cafdff777125cd3fb6d54/%E2%80%A6) mention returned by the Host. Its visible form is a chat-bubble glyph plus the business-color session title, without a capsule; serialization never reconstructs identity from that title. Ordinary send carries the canonical mention through session.prompt; the session-reference service validates it and captures model context at agent/pre-step.

The /client export is the plugin body (apply/inject) only; candidate encoding stays internal to the registration effect.

Model Experience

Indirectly, through @deepseek-ai/dsh-file-reference-local for path guidance and @deepseek-ai/dsh-session-reference for prepared session snapshots.

KV Cache effect

Candidate browsing has no model effect. A selected file or session changes only the new user-message suffix and any Host-prepared session-reference context that follows that message; earlier target history remains unchanged.

Known Limitations and Deferred Work

• Candidate failure is intentionally quiet — one unavailable or failed Remote discovery call yields no rows for that domain. A session-reference preparation failure occurs after prompt acceptance and terminates that agent turn.
• No browser-side file scan — Web completion requires a mounted Host ctx.fileReferences provider; the browser cannot fall back to its own filesystem.
• Session search remains metadata-only — discovery filters session id, cwd, and the latest log-backed title through ctx.sessionReferenceResolver; message bodies and full transcripts are not searched.
