_KermanandTianyi Cui fb79a944f5 refactor(llm): separate durable producer sources from request inputs
Give durable user context its producer-owned source kind instead of a generic plugin wrapper. The V3-to-V4 conversion preserves the frozen rename and collision rules, all own JSON metadata, event coordinates, and historical request-only kinds. Native catalog and JSONL admission retain source validation so unknown attribution can survive without its producer while malformed owned sources are refused.

Use an explicit user-only RequestUserInput for auxiliary LLM prompts that do not own durable message identity. Auto Review and compaction remove their request-only source registrations while retaining prompt content and freezing; provider serializers and projections keep the same wire data, assistant replay isolation, image ordering, and tool correlation. Session writes, Agent delivery, and recorded title requests continue to require identified durable messages.

Bind the saved compatibility policy only to user sources and qualify tmux location attribution without weakening fixed system, model, or tool semantics. Rebuild the current inventory and unpublished V4 acknowledgement on the actual tool-role parent, preserving its rationale and all accepted historical records. The catalog format version records tooling metadata; Session remains V4. Developer-role policy and activation belong to their own feature.

The latest-master Messages adapter, serialization, request-input typing, EpochHeader reservation, and attribution checks pass 103 tests across five files. The retained V3 Messages input-history snapshot passes through the source profile; Host/Client typechecks and all 41 documentation gates pass. The generated comparison records four changed roots and 447 unchanged type fingerprints. Latest-master ARIA changes are retained, with producer source labels applied independently; new Messages fixtures retain their producer names as declared source kinds and use the fixed system-message helper; recorded Session generations are unchanged by this regrouping.

Package map for the application's Remote layer: typed Client-to-Host capability calls, results, and forwarded events, for users and maintainers navigating the group. package-group

api/ — Remote API layers

English | 中文

Summary

The api/ group provides the application's Remote layer: a Client environment can call the business capabilities running on the Host — manage goals, run commands, list the plugin inventory, discover file and session references — as typed method calls, and receive the results or forwarded Host events. remotes decides which capabilities are exposed and how each call reaches the right session's agent; gateway carries the calls and their results between Client and Host. The stack runs over the application's shared Connection; streaming session data is deliberately outside it.

Packages

The packages below provide the Remote layer; the package READMEs own the exhaustive contracts.

Package Role ctx key
remotes/ Chooses which Host capabilities and events the Client can consume. —
gateway/ Carries typed unary calls, multiplexed streams, and forwarded Host events. ctx.typertGateway / ctx.remote
session-controller/ Owns Session commands, history streams, live control state, and Agent/Session identity policy. ctx.sessionController / ctx.remote.session
settings-controller/ Owns the configuration-surface reads and writes over the settings-domain seams. ctx.settingsController, ctx.credentialsController / ctx.remote.settings, ctx.remote.credentials
workspace-controller/ Owns Workspace mutations and the complete Client Workspace projection. ctx.workspaceController / ctx.remote.workspace
terminal-controller/ Session-owned interactive shells, screen recovery and browser terminal control. ctx.terminalController / ctx.remote.terminal
workspace-files/ Owns bounded workspace file access — stat, paged read, list, and the instrumented-operation changes feed — and the Client file resource provider over it. ctx.workspaceFiles / ctx.remote.workspaceFiles

Remote calls run Client → Host over the application's shared Connection. API Gateway owns Remote transport, while the controller packages own Session, configuration-surface, and Workspace behavior. Feature packages register exact Connection Fetch routes for responses that do not fit Remote invocation, such as streamed downloads.


Start with the API Gateway reference to see the Remote model end to end, then the Typert subsystem page for the shared definitions and Connection for the physical carrier.

  • API Gateway reference — the current-state reference for the Typert API Gateway: programming model, generation pipeline, and runtime invocation.
  • Typert subsystem reference — the public contracts shared by protocol, Gateway, and consumer assemblies.
  • Connection — the RPC carrier, /api trust fence, and response envelopes behind every Remote call.
