Summary

Shared code no longer imports OpenCode adapter modules (ADR-011). The OpenCode adapter registers its models at start-up. Users see no change.

  • ModelPort gains an optional completeStructured method.
  • registerHostProfileModel (services) and registerOpencodeHostModels (importer) replace direct adapter imports.
  • settings-models.ts moves from src/services/ to src/importer/.
  • ADR-011 records a follow-up: rebuild the V2 plugin natively and drop V1 in 4.0.0.
  • The OpenSpec change move-opencode-model-code-to-adapter is archived.

Tests

  • New: tests/profile-model-port.test.ts, tests/opencode-profile-model.test.ts, tests/opencode-host-models.test.ts. Each fails when the code under test is broken.
  • bun run ci:local passes.
  • Manual check in OpenCode V2: live capture ran on the host model zai-coding-plan/glm-5.3. The live profile learning and cleanup check was skipped because a standalone web UI held port 4747. Automated tests cover that routing.

Summary by CodeRabbit

  • Improvements
    • OpenCode profile learning and cleanup now use the host-provided model, with structured responses supported where available and the existing external API fallback retained.
    • OpenCode model availability is surfaced in Settings and health checks; web imports continue to report models as unavailable when no host model is registered.
  • Documentation
    • Updated architecture and setup guidance to reflect OpenCode model registration and host boundaries.

Shared code no longer imports OpenCode adapter modules. The OpenCode
adapter registers its profile model and import models at start-up.

- Add an optional completeStructured method to ModelPort.
- Add registerHostProfileModel in services and registerOpencodeHostModels
  in the importer.
- Move settings-models from services to the importer.
- Add regression tests for profile routing and the import model registry.
- Record the V1 removal follow-up in ADR-011.
- Archive the move-opencode-model-code-to-adapter OpenSpec change.

📝 Walkthrough

Walkthrough

OpenCode model code is organized under the adapter boundary. Shared profile and importer code now access host models through registrations. Importer session-title handling and boundary tests are updated to match the revised module ownership.

Changes

OpenCode model boundary

Layer / File(s) Summary
Adapter ownership and import boundaries
src/adapters/opencode/*, src/importer/opencode-internal-sessions.ts, src/importer/opencode-reader.ts, src/index.ts, src/v2/plugin.ts, tests/*, docs/*, openspec/*, AGENTS.md
OpenCode-related imports and profile-learning references use adapter paths. Internal capture-session titles are defined in the importer. Boundary tests and architecture records specify the updated import rules and ownership.
Profile model port and routing
src/core/profile-analysis.ts, src/services/user-profile/*, src/adapters/opencode/profile-model.ts, src/index.ts, tests/*, docs/shared-core.md, openspec/*
ModelPort supports optional structured completion. Profile operations resolve a registered host model and retain the external-API fallback. The OpenCode adapter provides plain-text and structured completion, including transient-session handling for plain-text completion.
Importer model registration and access
src/importer/*, src/adapters/opencode/backfill-startup.ts, src/index.ts, src/services/web-server.ts, tests/*, docs/*, openspec/*, AGENTS.md
OpenCode host registration exposes provider connectivity, import-model creation, and Settings model listing. Importer and web-server callers use the registered host models. Plugin startup registers the OpenCode profile and import models.

Loading

Merge Risk: 🟡 Moderate · up to e1633

Profile operations can fail instead of using the configured external API when OpenCode provider loading fails. Requests made soon after plugin startup can also report models unavailable or fail an import. Resolve these paths before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to e1633

Model-backed operations may become unavailable during startup, and some profile updates may stop rather than use a configured fallback when the host provider fails to load. The review found no new unauthenticated access path.

Retained concerns

  • Medium · reliability · inferred: Importer-model registration is not a prerequisite for exposing model-backed Settings and import operations. An early request can see no registered host; a failed dynamic import is silently swallowed and can leave those operations unavailable.
  • Medium · reliability · inferred: A provider-loading rejection from the newly registered profile resolver escapes before the duplicate, conflict, and description paths enter their host-operation catches. Unlike the parent behavior, those paths can abort instead of trying the configured external fallback.
Security review details

Security Blast Radius

  • inferred — The affected scope is model-backed profile work and authorized Settings/import operations within a running process. The inspected registration does not add an HTTP route or grant a caller new provider credentials.

Trust Boundaries and Controls

  • observed — Request authorization precedes model-dependent route handling, and import requests undergo readiness and selection checks before model acquisition or runner execution. Missing registration produces unavailability or a failed job, not an observed authorization bypass or partial import.

Resilience and Maintainability Implications

  • observed — An import job retains one retrieved host-model object for its connectivity check and factory call. Its existing cancellation signal, terminal states, and non-preview snapshot-discard path remain in place.

Hardening Proposals

  • proposed — Make importer registration readiness explicit before exposing model-dependent operations, and report registration failure rather than silently leaving the registry empty.
  • proposed — Keep provider-resolution failures within the profile fallback policy while preserving the existing distinction between an unavailable host and an error from an available host model.

- Around line 291-293: Update the startup flow in src/index.ts to await
registerOpencodeImportModels() before starting the web server or exposing its
routes, so requests cannot run before the OpenCode model registry is populated.

Review comments at @src/services/user-profile/profile-model.ts:
- Around line 14-20: Update the OpenCode resolver registered by
registerHostProfileModel so loadOpencodeProvider failures return null, allowing
callers to use the configured external API fallback. Keep errors from an
available host model propagating unchanged.

- Treat a host profile model that fails to resolve as unavailable, so
  dedup, conflict and description checks keep the external API fallback.
- Await OpenCode import model registration before the web server starts.
