What

Two major changes in this PR:

Phase C: Real Embedding Integration (#244)

Replace placeholder fake embeddings with real embed service calls
Add embed-service.ts (remote API + cosine similarity + fallback)
sync.ts/query.ts now async, call embed service
Fix Buffer.from for sqlite Uint8Array in loadAllChunks

Remove AgentRegistry (#245)

RoleSpec: agent: string → adapter: AgentFn (direct import, compile-time safety)
Remove timeout from RoleSpec (adapter concern)
Delete AgentRegistry + tests (-822 lines)
Each adapter exports default instance + factory: cursorAdapter / createCursorAdapter()
Extract merge simplified: 3-level → 2-level (global → role)
compileWorkflowSpec calls roleSpec.adapter() directly, no lookup
RFC-003 updated to reflect new design

Why

Real embeddings enable actual semantic search in knowledge layer
AgentRegistry was unnecessary indirection — adapter is the capability, roles reference it directly via import

Changes

packages/cli/src/knowledge/ — embed-service.ts, async sync/query, tests
packages/core/src/workflow-spec.ts — RoleSpec simplified to 3 fields
packages/daemon/src/agent-registry.ts — deleted
packages/daemon/src/compile-workflow-spec.ts — no registry dependency
packages/adapter-cursor/ + packages/adapter-hermes/ — export default + factory
packages/workflow-utils/ — 2-level extract merge
docs/rfc-003-agent-config-layer.md — updated design

Fixes #245

feat(knowledge): integrate real embedding service ce5462cb59

Replace placeholder fake embeddings with real embed service calls:
- Add embed-service.ts (remote API + cosine similarity + fallback)
- knowledge-db stores externally-provided embeddings
- sync.ts/query.ts now async, call embed service
- CLI commands updated for async API

WIP: tests need updating for async changes

Refs #234

test(knowledge): update tests for async embed service integration 7bb6990dc5

- Mock embed service in sync/query tests (1024-dim vectors)
- Fix Buffer.from for sqlite Uint8Array in loadAllChunks
- Add pretest to workflow-utils for build order

All tests passing.

rfc-003: simplify agent layer — remove registry, roles declare adapter directly 732669fab5

- Remove nerve.yaml agents config (keep only extract + knowledge)
- RoleSpec.agent → RoleSpec.adapter
- buildWorkflowSpec receives adapter map directly
- Extract merge: 3-level → 2-level (global → role)
- Update open questions (embedding service resolved)

rfc-003: adapter as direct function reference, not string 4be465918c

- RoleSpec.adapter: string → AgentFn (direct import)
- Each adapter exports default instance + factory
- No adapter map, no registry, no lookup — compile-time safety
- TypeScript catches missing adapters at import time

Refs #245

rfc-003: remove timeout from RoleSpec, it's an adapter concern 7de75b5df7

RoleSpec now has exactly 3 fields: adapter, prompt, meta.
Timeout belongs to adapter config — different timeouts = different adapter instances.

feat(core): remove AgentRegistry, roles declare adapter directly ede59ebcc2

RoleSpec uses adapter: AgentFn; timeouts are configured via adapter factories.

nerve.yaml no longer accepts agents:; extract merge is global to role only.

Added cursorAdapter/hermesAdapter defaults; removed daemon registry and deps.

✅ Hermes Agent Review — APPROVED

总评

两个大改动合在一个 PR 里但逻辑清晰：embedding 真实接入 + AgentRegistry 移除。净删 330 行（+624 -954），架构更简洁了。

✅ Real Embedding Integration

embed-service.ts — 干净的 client，auto-batch（100 条/批），Float32LE encoding 存 SQLite BLOB，cosine similarity 实现正确
Graceful fallback — resolveEmbedConfig() 从环境变量取，未配置时 fallback 到 fake embedding，不 crash
sync.ts 改 async — 合理，embedding 是网络调用
query.ts 双模式 — 有 embed config 用 cosine，没有用 word overlap，对用户透明
knowledge-db.ts — Buffer.from(r.embedding) 修复了 SQLite node:sqlite 返回 Uint8Array 的问题 ✅
KnowledgeChunkInsert 加了 embedding 字段 — 不再在 db 层调 fakeEmbeddingBytes，embedding 计算提前到 sync 层，职责更清晰

✅ Remove AgentRegistry

RoleSpec 简化 — agent: string + timeout → adapter: AgentFn，3 个字段够了，编译期类型安全
compileWorkflowSpec 大幅精简 — 不再需要 registry lookup / timeout resolution / signal merge，直接调 roleSpec.adapter()
Kernel 瘦身 — 移除 AgentRegistry 相关的 import、创建、reload log、getAgentRegistry 暴露
Extract merge 3→2 级 — global → role 就够了，agent 层中间商去掉合理（timeout 已经是 adapter 内部事了）
Default adapter instances — cursorAdapter / hermesAdapter 导出默认实例，workflow 里直接 import 用，零配置

💡 Minor（不阻塞）

resolveEmbedConfig 每次 query/sync 都读 env — 可以考虑 init 时读一次缓存。当前性能无影响，只是风格偏好
cosine similarity 未处理 NaN — 如果两个 embedding 都是全零向量，denom = 0，返回 0 是对的。但如果 buffer 长度不一致（不同 model 的 embedding 混用），Math.min 会静默截断。可以加个 assert
parseDurationStringToMs 和 resolveRoleTimeoutMs 还在 core 里导出，但现在没人用了（timeout 是 adapter 内部事）。可以清理或标记 deprecated

设计决策评价

移除 AgentRegistry 这个决策很果断。上一个 PR 刚加的 plugin 模式，这个 PR 就意识到 registry 是不必要的间接层——adapter 就是 capability，直接 import 比按名查找更安全、更简单。这种"发现过度设计就立刻修正"的习惯很好 👍
