# Journal - Apale (Part 1) > AI development session journal > Started: 2026-04-16 --- ## 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. ### Git Commits | Hash | Message | |------|---------| | `eeacdc4` | (see git log) | | `00747fa` | (see git log) | | `ca0b3c4` | (see git log) | ### Testing - [OK] (Add test results) ### Status [OK] **Completed** ### Next Steps - None - task complete ## Session 2: Build OPS MVP failover proxy **Date**: 2026-04-17 **Task**: Build OPS MVP failover proxy **Branch**: `master` ### Summary Implemented the Go-based OPS MVP: local config, provider and alias CLI, OpenCode sync/import, and a streaming OpenAI Responses proxy with deterministic pre-first-byte failover. Added Chinese and English README documentation for quick onboarding. ### Main Changes (Add details) ### Git Commits | Hash | Message | |------|---------| | `2b04d91` | (see git log) | ### Testing - [OK] (Add test results) ### Status [OK] **Completed** ### Next Steps - None - task complete ## Session 3: Support disabling providers in ocswitch **Date**: 2026-04-17 **Task**: Support disabling providers in ocswitch **Branch**: `master` ### Summary Added provider-level disable/enable support, made failover skip disabled providers without mutating alias target state, and aligned doctor/opencode sync/models exposure with routable aliases. ### Main Changes (Add details) ### Git Commits | Hash | Message | |------|---------| | `HEAD` | (see git log) | ### Testing - [OK] (Add test results) ### Status [OK] **Completed** ### Next Steps - None - task complete ## 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/cli/alias.go` - `internal/cli/opencode.go` - `internal/cli/doctor.go` - `internal/cli/serve.go` - `internal/opencode/opencode.go` - `internal/proxy/server.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. ### Git Commits (No commits - planning session) ### Testing - [OK] (Add test results) ### Status [OK] **Completed** ### Next Steps - None - task complete ## 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.` 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. ### Git Commits | Hash | Message | |------|---------| | `887eb14` | (see git log) | ### Testing - [OK] (Add test results) ### Status [OK] **Completed** ### Next Steps - None - task complete ## Session 6: Rename CLI to ocswitch **Date**: 2026-04-17 **Task**: Rename CLI to ocswitch **Branch**: `master` ### Summary Renamed the CLI and synced docs, examples, and Trellis history from olpx/opswitch to ocswitch while keeping the repository name opencode-provider-switch. ### Main Changes (Add details) ### Git Commits | Hash | Message | |------|---------| | `cf3dcec` | (see git log) | ### Testing - [OK] (Add test results) ### Status [OK] **Completed** ### Next Steps - None - task complete ## 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 ./...` ### Git Commits (No commits - planning session) ### Testing - [OK] (Add test results) ### Status [OK] **Completed** ### Next Steps - None - task complete
