Replace the legacy reference.* API Proxy domain with @Remote methods on the owning services, following the typert gateway design master adopted on 2026-08-02 (message-feedback and plugin-inventory precedents): - FileReferenceService and SessionReferenceResolver extend TypertRemoteService; fileReferences/list and sessionReferenceResolver/candidates are unary Remote methods cancelled through the reserved trailing signal, and the candidates face attaches each candidate's canonical mention under the configured limit - move the wire types to type-only ./types subpaths (FileReferenceCandidate, SessionReferenceMentionCandidate) and export ./typert plus ./remote artifacts - mount both contributions in the api-remotes client assembly; ui-reference consumes ctx.remote instead of connection.api.references and registers zh/en locale dictionaries for its sections and labels - delete the reference.* routes, schemas, map rows, client stubs, and fixtures; the connection fixture serves the Remote endpoints instead - release deliverPrompt admission listeners when the agent is disposed with the prepared prompt still pending, and cover the reference-* RpcError codes in the schema spec - add the missing tsconfig paths for the /grammar and /types subpaths (clean- tree vitest could not resolve @deepseek-ai/dsh-file-reference/grammar) - regenerate the cordis catalog, capability seams, and event matrix; update the owning bilingual READMEs, Agent Notes, and the reference-composer golden

File-reference discovery seam and browser-safe @file grammar shared by host-backed user interfaces. ctx.fileReferences.list(agent, query, signal) returns path-only file or directory candidates for the addressed agent; concrete providers own namespace access, ranking, caching, and invalidation. The same contract is remotely callable as the unary fileReferences/list Remote method (@Remote on the Service Definition, cancelled through the reserved trailing signal), so browser consumers call ctx.remote.fileReferences.list without an API Proxy route.
activeAtToken() recognizes an @path or open @"path with spaces token only at the start of input or after whitespace, so email-like text does not open completion. formatFileMention() emits the matching prompt spelling, appends / to directory candidates, preserves an explicitly opened quote, and rejects control characters or embedded quotes that the editor grammar cannot represent safely.
Selecting a candidate does not read or attach file contents. The exported FILE_REFERENCE_PROMPT is stable guidance that a provider may install when the addressed agent can call read.
Model Experience
Indirectly, through @deepseek-ai/dsh-file-reference-local, which conditionally contributes this package's stable file-reference guidance.
KV Cache effect
The interface and grammar add no request tokens themselves; a provider-owned prompt section determines cache behavior.
Known Limitations and Deferred Work
- Path candidates are advisory — the seam does not prove that a later model-facing filesystem tool can access the same namespace; deployments must align the provider with the effective
readimplementation. - No file-content reference object — selected files remain ordinary prompt text and require an explicit model tool call before their contents become model-visible.
