# REPORT: Knowledge RAG Runtime Wiring and OpenCode SDK Alignment

This report summarizes the work completed on 2026-06-01 so the repository owner can review the exact scope, evidence, and remaining release actions.

---

## 1. Executive Summary

The existing Second Brain plan was **partially correct but not fully implemented** at runtime.

Completed in this session:

- Knowledge RAG Phase 5 was wired into `experimental.chat.system.transform`.
- Repository knowledge now comes from `docs/**/*.md` and `.opencode/docs/**/*.md`.
- `assistant.done` usage was removed and replaced with a supported `message.updated` completion bridge.
- OpenCode dependency ranges were aligned with the verified latest package version `1.15.13`.
- Docs were updated to match the code.
- Build, full tests, and package dry-run all passed.

Additional execution after the report checkpoint:

- implementation commit `22001ef` was created and pushed to `origin/main`
- patch release was attempted
- local release commit `35d5238` and local tag `v1.3.3` were created
- Windows `NPM_TOKEN` was verified via `npm whoami`
- `opencode-orchestrator@1.3.3` was published successfully

---

## 2. Tasks Completed

### 2-1. Plan Audit

- Re-read `docs/histories/2026/05/31/PLAN_SecondBrainOrchestration_2026-05-31.md`
- Verified that Phase 5 was still documented as deferred while code had no runtime injection
- Verified that the planned vault root `docs/knowledge/` did not exist in the repository

### 2-2. SDK Alignment

- Verified current package versions:
  - `@opencode-ai/plugin` `1.15.13`
  - `@opencode-ai/sdk` `1.15.13`
- Verified official hook typings
- Confirmed that `assistant.done` is not part of the current hook surface

### 2-3. Runtime Refactor

- Added `src/core/knowledge/context-provider.ts`
- Connected knowledge retrieval to `src/plugin-handlers/system-transform-handler.ts`
- Switched assistant-turn completion handling to `message.updated` completion events
- Added `lastCompletedMessageID` tracking to prevent duplicate completion processing
- Replaced hardcoded plugin hook names with expanded constants where used

### 2-4. Test Coverage Added

- `tests/unit/assistant-done-handler.test.ts`
- `tests/unit/event-handler.test.ts`
- Expanded `tests/unit/system-transform-handler.test.ts`

### 2-5. Documentation Updated

- `README.md`
- `docs/SYSTEM_ARCHITECTURE.md`
- `docs/histories/2026/05/31/PLAN_SecondBrainOrchestration_2026-05-31.md`

## 5. Findings

### Confirmed Before Fix

1. Knowledge RAG modules existed but were not wired into the runtime prompt path.
2. The repository plan assumed a dedicated `docs/knowledge/` vault, but the actual repository only had `docs/` and `.opencode/docs/`.
3. The plugin referenced `assistant.done`, which is incompatible with the currently installed OpenCode SDK surface.

### Confirmed After Fix

1. Orchestrated sessions now receive knowledge matches through `experimental.chat.system.transform`.
2. Assistant completion processing now runs through supported `message.updated` events.
3. Documentation and package metadata now reflect the verified code state more closely.

## 6. Remaining Items

No release execution items remain incomplete.

Final release execution sequence:

- `npm run release:patch` initially failed because bash did not inherit the Windows `NPM_TOKEN`
- direct follow-up execution used a temporary npm user config populated from the provided token
- token-backed `npm whoami` succeeded as `agnusdei12071207`
- token-backed `npm run publish:token` then published `opencode-orchestrator@1.3.3`
- `git push origin main` pushed the release lineage
- `git push origin --tags` pushed `v1.3.3`

Current repository state:

- `origin/main`: includes the release lineage and publication record commits
- local `main`: aligned with `origin/main`
- remote/local tag: `v1.3.3`
- npm registry latest observed version: `1.3.3`
- untracked unrelated path: `.antigravitycli/`

---

## 7. Reviewer Checklist

- [ ] Confirm the 2026-05-31 plan correction is acceptable
- [ ] Confirm the new knowledge roots are the intended repository sources
- [ ] Confirm event-based completion bridging is preferable to keeping dead `assistant.done` wiring
- [x] Push `main` and `v1.3.3` to origin
