xiaoju 852cad9c60 docs(rfc-001): archival watermark + workflow_runs materialized table 
- Cold archival: meta table with archived_up_to watermark for crash-safe recovery
- Workflow state: workflow_runs materialized table (UPSERT in same txn as log write)
  - O(active) queries instead of full table scan
  - Derivable from logs if lost

xiaoju f5c561173d docs(rfc-001): add Log concept, append-only storage architecture, workflow event sourcing 
- §2.4: Log as data asset, not trigger source (anti-avalanche constraint)
- §3: Add Log to terminology table
- §5.4: New storage architecture section
  - Unified logs table (append-only SQLite)
  - Workflow state via event sourcing (no mutable tables)
  - Cold archival: >30d data exported to daily JSONL files
- §5.6: Error handling now writes logs instead of error signals
- §8: Directory structure updated with logs.db and archive/
- §10: Design principles updated (8 principles, +1 log rule)
- Thread outputs are now Logs, not Signals

xiaoju 643c353cc3 feat(rfc-001): 回应小墨 review — runtime 注入 db/peers、migration rollback、drizzle config、schema 新鲜度 2026-04-22 05:54:56 +00:00
xiaoju 8a3937f0e1 feat(rfc-001): Drizzle 作为 Sense schema 标准工具链 
- schema.ts 为 single source of truth，migration 由 drizzle-kit 自动生成
- Sense 目录结构从单文件改为目录（schema.ts + index.ts + migrations/）
- 设计理由：开发者是 Coding Agent，确定性工具链优于概率模型自律
- 更新 §4.1 存储设计、§8 目录结构

xiaoju 8379dae585 fix(rfc-001): 解决小墨 review 的生产风险问题 
- 删除 Guard 表达式（when），条件判断由 Workflow 自己处理
- Workflow queue 加 max_queue 上限（默认 100）
- compute 超时改为两级：soft timeout + grace_period hard kill
- 热更新加 drain_timeout，防止长 thread 阻塞 reload

xiaoju 6e49deaf99 refactor(rfc-001): Reflex 作为 Event Mesh，Sense 不知道 Workflow 
- 删除 Sense → Workflow 桥接（ThreadStart payload），Sense 只产出数据
- Reflex 新增两种 action：TriggerCompute / StartWorkflow
- 引入 Event Mesh 概念：所有事件路由声明在 Reflex 中
- 更新依赖图、Haskell 类型签名、设计原则
- 删除 should-cleanup sense（改由 Reflex when 守卫实现）

xiaoju aa5b0c6349 docs: workflow concurrency/overflow, signal-thread boundary 
Signal only kicks off Thread. Thread has its own event loop.
Thread output signals are execution logs for retrospection only.
