## Session 1: Finalize OPS MVP review PRD

**Date**: 2026-04-17
**Task**: Finalize OPS MVP review PRD
**Branch**: `master`

### Summary

(Add summary)

### Main Changes

| Area | Description |
|------|-------------|
| PRD Redesign | Reframed OPS MVP around alias-driven multi-provider failover for OpenAI Responses only. |
| OpenCode Integration | Locked config-sync approach for exposing aliases through `provider.ops.models`, with connected-provider requirement. |
| Failover Semantics | Finalized pre-first-byte-only failover, streaming pass-through, and no mid-stream provider switching. |
| MVP Boundaries | Locked import scope to config-defined `@ai-sdk/openai`, excluded `auth.json` as provider definition source, and kept `ops doctor` static by default. |
| Task Closure | Marked review task completed, cleared current task, and archived both finished docs tasks. |

**Updated Files**:
- `.trellis/tasks/archive/2026-04/04-17-04-17-ops-mvp-design-review/prd.md`
- `.trellis/tasks/archive/2026-04/04-17-04-17-ops-mvp-design-review/task.json`
- `.trellis/tasks/archive/2026-04/04-17-ops-mvp-design/task.json`

**Notes**:
- Follow-up implementation should start in a new task from the finalized PRD.
- Existing unrelated worktree change in `AGENTS.md` was left untouched.

## Session 4: Review MVP completion status

**Date**: 2026-04-17
**Task**: Review MVP completion status
**Branch**: `master`

### Summary

Reviewed current implementation against the archived MVP PRD and classified implemented, missing, and beyond-MVP features.

### Main Changes

| Category | Result |
|---|---|
| Overall status | MVP core flow is effectively complete |
| Implemented MVP | Local ocswitch config, provider/alias CLI, OpenCode sync, static doctor, `/v1/responses` proxy, streaming pass-through, pre-first-byte failover, debug headers |
| Partial / missing MVP edges | `doctor` validates generated preview more than on-disk synced state; OpenCode provider import only reads `options.apiKey`, not broader header-style auth |
| Beyond MVP | `provider enable/disable`, minimal `/v1/models`, broader alias normalization, careful OpenCode config patching |

**Reviewed Sources**:
- `.trellis/tasks/archive/2026-04/04-17-04-17-ops-mvp-design-review/prd.md`
- `internal/config/config.go`
- `internal/cli/provider.go`

- `internal/proxy/server_test.go`
- `internal/opencode/opencode_test.go`
- `internal/cli/cli_test.go`
- `internal/config/config_test.go`

**Verification**:
- Ran `go test ./...` successfully: 34 tests passed across 5 packages.

## Session 5: Fix sync command panic

**Date**: 2026-04-17
**Task**: Fix sync command panic
**Branch**: `master`

### Summary

Fixed a panic in opencode sync when preserved model metadata contains slices, and added package plus CLI regression coverage.

### Main Changes

- Root cause: `internal/opencode/opencode.go` compared `interface{}` values directly inside `mapsEqualShallow`, which panicked when preserved `provider.ocswitch.models.<alias>` metadata included slices.
- Fix: replaced the unsafe hand-rolled comparison with `reflect.DeepEqual` so existing model metadata with nested maps/slices can be compared safely during `sync`.
- Added regression tests in `internal/opencode/opencode_test.go` and `internal/cli/cli_test.go` covering preserved slice metadata and a real `opencode sync --target` no-op path.
- Verification: ran `rtk go test ./internal/opencode`, `rtk go test ./internal/cli ./internal/opencode`, and `rtk go test ./...` successfully.

## Session 7: Deep code review for ocswitch

**Date**: 2026-04-17
**Task**: Deep code review for ocswitch
**Branch**: `master`

### Summary

Recorded the deep code review findings in Trellis, including 2 high-risk, 4 medium-risk, and 4 low-risk/improvement items with concrete remediation guidance.

### Main Changes

- Added `.trellis/tasks/04-17-deep-code-review-ocswitch/review.md` to capture the full deep review output and concrete remediation guidance.
- Recorded 2 high-risk items:
  - concurrent config/OpenCode save paths are unsafe under concurrent writers
  - proxy request body has no read timeout after headers
- Recorded 4 medium-risk items:
  - streaming responses have no idle timeout
  - retryable upstream failures are collapsed into a generic `502`
  - `opencode sync --set-model` / `--set-small-model` can silently write invalid defaults
  - fixed default API key remains unsafe when binding to non-loopback addresses
- Recorded 4 low-risk or improvement items:
  - alias lifecycle lacks enable/disable recovery path
  - provider import docs and implementation disagree on empty `apiKey`
  - `opencode sync` side effects on JSONC comments and `$schema` need clearer docs
  - header forwarding should better handle dynamic hop-by-hop headers and narrower forwarding rules
- Verification already completed during review:
  - `go test ./...`
  - `go test -race ./...`

## Session 9: GUI desktop direction and architecture decision

**Date**: 2026-04-18
**Task**: forwarding-log-viewer-gui
**Branch**: `master`

### Summary

Recorded the GUI direction change from a local web-only surface to a desktop-shell follow-up, driven by explicit requirements for launch at login, native menu/tray integration, and native notifications.

### Main Changes

- Confirmed the existing Trellis task `04-17-forwarding-log-viewer-gui` remains historically correct as a completed local web log-viewer design task and should not be retrofitted in place.
- Recorded follow-up product guidance that desktop capabilities now justify a separate native-shell track rather than a browser-only UI.
- Captured the recommended follow-up stack as `Wails + React + TypeScript + Tailwind CSS + react-hook-form + zod`.
- Captured the preferred layering so existing Go logic is not rewritten into desktop-specific code:
  - `internal/config` continues config IO and validation
  - `internal/proxy` continues proxy runtime and failover
  - `internal/opencode` continues OpenCode sync
  - new `internal/app` application service layer is shared by CLI and GUI
  - Wails desktop shell owns window, tray/menu, notifications, autostart, and frontend hosting only
- Recorded the frontend recommendation that React is a better fit than Vue for this project because the desktop control panel is form-heavy and aligns better with the chosen `react-hook-form + zod` stack.

### Git Commits

(No commits - Trellis documentation update only)

### Testing

- [OK] No code changes; updated Trellis task metadata and workspace journal only

### Status

[OK] **Completed**

### Next Steps

- Create a separate Trellis task for the desktop shell if implementation should proceed


## Session 10: Desktop shell skeleton implementation

**Date**: 2026-04-18
**Task**: Desktop shell skeleton implementation
**Branch**: `master`

### Summary

Implemented the first desktop-shell skeleton by introducing a shared internal/app layer, desktop preference persistence, CLI reuse of shared workflows, and a minimal desktop bootstrap with passing Go tests/builds.

### Main Changes

- Added `config.Desktop` to persist desktop-shell preferences (`launch_at_login`, `minimize_to_tray`, `notifications`) without coupling core runtime logic to a desktop framework.
- Added `internal/app/types.go` and `internal/app/service.go` as the shared application-service layer described in the PRD.
- Implemented shared DTOs and workflows for:
  - overview
  - provider listing
  - doctor report generation
  - OpenCode sync preview/apply plumbing
  - proxy lifecycle management
  - desktop preference read/write
- Refactored CLI reuse points so `doctor`, `opencode sync`, `provider list`, and `serve` now delegate through `internal/app` instead of keeping those orchestration paths CLI-only.
- Preserved CLI output behavior closely while centralizing the orchestration logic that future desktop bindings can call.
- Added `internal/desktop/` skeleton adapters (`app`, `bindings`, `tray`, `notify`, `autostart`) as placeholders for a future Wails/native shell integration, keeping desktop-only concerns outside `internal/app`.
- Added `cmd/ocswitch-desktop/main.go` as a minimal desktop bootstrap binary that exercises the shared bindings and confirms the skeleton is wired.
- Added `internal/app/service_test.go` to cover desktop preference persistence and proxy start/stop status flow.
- Verified the implementation with:
  - `gofmt -w ...`
  - `rtk go test ./...`
  - `rtk go build ./...`
- Scope intentionally stayed at the PRD's recommended “skeleton wiring only” level: no Wails dependency, no React frontend, and no tray/autostart implementation yet.
