信封改造（最低风险，最先做） + +### 目标 +每行 trace 从裸事件变为 Codex 式信封，文件自身携带顺序与时间。 + +### 设计 + +```rust +// runtime/src/state/trace.rs（新） +#[derive(Serialize, Deserialize)] +pub struct TraceLine { + /// RFC3339 UTC + pub ts: String, + /// 单调递增，由 writer 内存计数器分配（不再查 SQLite） + pub seq: u64, + pub event: StreamEvent, +} +``` + +要点： +- **seq 来源改为内存计数器**：writer 创建时从 `index.last_event_seq()` 读一次初始值，之后纯内存递增。消除每次 append 一次 DB 查询，也消除"DB 分配成功但写文件失败"的半提交态。 +- append 成功后再把 `(run_id, seq, event_name)` 冗余写入 index 的 `events` 表（保持现有 SSE 续读功能不变），但**文件是权威**，index 只是加速。 +- 兼容读取：`read_trace(path)` 逐行尝试解析 `TraceLine`，失败则回退按裸 `StreamEvent` 解析（旧 trace 无 seq，按行号补 seq）。旧文件**不做批量迁移**，惰性升级。 + +### 实施步骤 +1. `runtime/src/state/trace.rs`：新增 `TraceLine`，改 `append_line` 为写信封，加内存 seq 计数器。 +2. `runtime/src/state/index.rs`：`append_event` 保持签名不变（调用方传的 seq 已有值）。 +3. 新增 `runtime/src/state/trace_reader.rs`：兼容新旧两种行的读取器（后续 Phase 6 复用）。 +4. 更新所有构造 TraceWriter 并依赖旧格式的测试（grep `trace.jsonl` 与

// 展示事件 + TurnContext(TurnContextItem), +} +// TraceLine.event 类型从 StreamEvent 改为 TraceEntry +``` + +> 注意：Phase 1 先落了 `TraceLine{ts,seq,event:StreamEvent}`，本 Phase 把 event 字段类型升级为 `TraceEntry`。trace reader 按 tag 兼容两种版本（无 tag 的旧对象视为 Ui 流 + 从中抢救 History 部分，规则见映射表；实在不含完整输出的旧文件只恢复 Ui 流并在 resume 结果上标注 `degraded: true`）。 + +### SSE 兼容层 +对外 SSE 事件**本期不改**：api 的 `message_adapter.rs` 改为从内部 `UiEvent + History 通知` 合成出既有 SSE DTO，保证 desktop/web 零改动。协议冻结在 Phase 4 再动。 + +### 实施步骤 +1. core 新建 `history.rs` 定义 `HistoryItem`（复用现有 `AssistantTurn/ToolCallRef/Usage` 类型，勿重复造）。 +2. foundation/events.rs：`StreamEvent` 拆为 `UiEvent`（保留原 serde 表示以稳住内部消费者）；新增 `TraceEntry`。 +3. engine/agent 主循环：在产出 AgentEvent 的位置同时发出对应 History 项（一次性埋点，参考 codex `record_canonical_items` 的"规范项优先"思想）。 +4. trace.rs 写入改为 `TraceEntry`。 +5. resume.rs 过渡版：从 trace 提取 `Vec` 作为模型上下文重放输入（Phase 6 再升级为 InitialHistory 三态）。 +6. message_adapter.rs 加合成层，跑通现有 web/desktop 回归。 + +### 测试 +- 快照：同一次 fake-provider run 的

`apps/api` 收编 DTO」，而是「从 `rove-runtime`/`rove-core` 下沉协议词汇」。** +> 计划假设 DTO 集中在 `apps/api/src/types.rs` 与 `product/contracts.rs`，机械搬迁即可。实际读过后两个前提都不成立：`product/contracts.rs`（2451 行）同时 import `StateStore` 与 `async_trait`，不是纯 DTO 文件，搬不动；而 `types.rs` 里的 DTO 全部由 `utoipa::ToSchema` 派生，搬进一个「零 utoipa」的 crate 自相矛盾。 +> 真正跨全仓、且真正需要零依赖的，是**标识符与生命周期枚举**——它们同时出现在落盘 artifact、HTTP 路径和 SSE 载荷里。因此 crate 的内容改为 `SessionId/JobId/RunId/CallId` + `RunStatus/ApprovalPolicy/RunMode/ApprovalDecision` + `PROTOCOL_VERSION` + `Versioned`。 +> 关键发现：这些类型都是平凡 newtype 与平凡 serde enum，**用 re-export 保留历史路径即可让 1718 处调用点全部不动**。这使得「真零 tokio 叶子 crate」从「需要重写 2800 行」变成零迁移成本。OpenAPI schema 之所以不受影响，是因为 `apps/api` 本来就在使用处挂 `#[schema(value_type = String, format = "ulid")]`，而不是依赖类型自带的 derive。 +> +> **D2 —— 「`apps/api/src/lib.rs` 行数下降 ≥30%」不可能通过 DTO 外移达成，本期不追求该指标。** +> `lib.rs` 5802 行里有 62 个 `async fn` handler，而 `pub struct` 只有 **1 个**（`ApiState`，:76）。里面没有 DTO 可以外移，该指标的前提（"靠 DTO 外移达成"）在这个文件上不存在。要减这 5802 行只能拆 handler 或迁 store，那是 Phase 5 的范围，不是协议拆分的副产品。 +> 本期实际的行数结果是净减 50 行，且减少发生在 `runtime`/`core` 而非 `apps/api`。 +> +> **D3 —— 「把 crate 放在 `rove-models` 之下以避开 tokio」的路径不成立；`rove-protocol` 直接成为全仓叶子。** +> `models/Cargo.toml:16` 自身就是 `tokio.workspace = true`（经 reqwest 传入），`rove-core` 也直接依赖 tokio。因此「在 models 之下」并不等于「无 tokio」。实际做法是让 `rove-protocol` 不依赖任何 local crate，由 `models` 之外的所有层向下引用它。架构守卫相应更新：`rove-protocol` 的 local 依赖集必须为空，且任何 crate 引用它都不算方向违规。 +> +> **D4 —— 「desktop 复制了 DTO、需要单独切换」不成立。** +> `apps/desktop/Cargo.toml:11` 整体依赖 `rove-api`，`api_server.rs` 只用 `embedded_api_state, serve_state_listener` 两个符号，没有任何 DTO 副本。desktop 因此随 api 自动获得新协议，无需改动。 +> +> **顺带修复：`/jobs/{job_id}/events` 的 OpenAPI 响应描述与真实帧形状不符。** 原描述为 "SSE stream of JobStreamEvent payloads"，但 `JobStreamEvent` 有 `seq` 与 `event` 两个字段，而真实帧把 `seq` 放进 SSE 的 `id:` 行、`data:` 里只有事件本体。加了 `v` 之后这个偏差更明显，故一并把描述改为逐字段说明真实布局。 + +--- + +## Phase 5 — Store 收拢：单 state.db 派生索引 + +### 设计 + +把两套 SQLite

产品目录这一侧不需要迁移：恢复能力来自新增的 sidecar 文件与 `recover_session_ownership` 读路径，既有表结构一列未改。所以"真实数据副本演练"落在 v3→v4：测试 fixture 由真实重放 migration 1..=3 构造，而不是手写一个近似的 v3 库。 + +> 分歧记录（§0.3 规则） +> +> **文档说「消息内容在 DB

表。产品库这一侧也没有任何 transcript 内容（`product_session_controls.content` 存的是**待投递**的 steer/followup 请求，在 applied 之前它就是权威记录，不是副本）。 +> 表里剩下的 `events.event_json` 是 UI 事件投影——一个派生缓存，而本期正是让它重新变得**可派生**（身份头 + backfill）。把 SSE 读路径改成扫 JSONL 只会用文件 I/O 换掉一次索引查询，并不减少任何冗余，故不做。 + +> 设计取舍：身份头占 `RUN_META_SEQ = 0` 而不从事件计数器取号。 +> 起初它像普通行一样 `fetch_add(1)`，结果 `api` 套件 4 个测试变红——`?after=N` 与 SSE `Last-Event-ID` 是**对外 wire contract**，锚在"首个事件是 seq 1"上。头行吃掉 seq 1 会把 `run_started` 顶到 2，向已经确认过事件 1 的客户端重放它。事件序号从 1 起（`after=0` 意为"全部"），所以 0 是唯一任何事件都不会占的槽位，正适合放一条描述文件本身、不属于事件流的行。 + +> 设计取舍：`recover_run_identity` 与 `record_run_started` 分开，且只插不覆盖。 +> 身份头说得清"这个 run 属于谁"，说不清"它怎么结束的"。若复用 `record_run_started`，它会把 `'running'` 盖到 report 导入刚恢复出的真实状态上——一个早已结束的 run 会在列表里显示为仍在运行。所以恢复路径全部 `ON CONFLICT DO NOTHING`，只补缺失的行，已有行一律不动；无 report 可依据时状态记 `interrupted`（诚实的"没跑完"）而不是 `running`。 + +> 附带修复：无身份头的 pre-Phase-5 旧 trace 会被跳过并 warn，而不是让整次 repair 失败。 +> 这类文件没有 `runs` 行可依，后续每次 `events` 插入都会撞外键。跳过它、留下

的归档是目录（`state_dir/runs//`）之外的**目录信息**，移动文件会同时打断 SSE 续传的 run 寻址和按 run 下载产物。本期只让列表接受 `include_archived` 参数，归档语义一个字没改。 + +> 分歧记录（§0.3 规则） +> +> **文档的游标是 `Cursor { ts, id }`，实际是三段式 `{ r, u, i }`（rank +

`MAX_PRODUCT_SESSIONS = 2048` 是 `enforce_table_limit` 施加在 `product_sessions` **整表**（不是每 workspace）上的写入上限，`create_session` 到 2048 就拒绝，10k 生不出来。读路径不关心行是怎么来的，所以 fixture 直接

`listWorkspaceFiles` 已有的 `cursor` / `next_cursor` 先例（同样是复合键）。不透明不等于可信：`ProductSessionCursor::decode` 对长度、base64、字段完整性、rank 取值、时间戳长度逐项校验，畸形游标一律 400。 + +> 分歧记录（§0.3 规则） +> +> **`include_archived` 默认

分组下发，一页最多两次 seek。 +> 让 rank 参与 keyset 比较，谓词必须写成三路 OR（`rank > ?` OR `rank = ? AND ts < ?` OR `rank = ? AND ts = ? AND id > ?`）。实测（`EXPLAIN QUERY PLAN`）SQLite 在这种形状下无法确认索引扫描已经有序，会物化后排序——代价随 workspace 增长，正是分页要消掉的那笔。把 rank 钉成等值后，`ORDER BY` 里**不再出现 rank**（组内它是常量），索引扫描顺序即结果顺序。rank 只有两个取值，所以一页最多两次子查询。 +> 反直觉之处已写进 `rank_page_sql` 的注释：这里若按"更自然"的写法把 rank 加回 `ORDER BY`，结果依然全对，只有查询计划会退化——上面的变异表第 5 行就是这一条。 + +> 附带发现：分页之前，`MAX_PRODUCT_SESSIONS = 2048` 同时充当列表 `LIMIT`。也就是说 workspace 超过 2048 个会话后，尾部会被**静默截断且无法请求**。文档没有点出这一条，它才是本期最硬的理由。 + +> 附带修复：迁移 015 加 `table_exists("product_sessions")` 守卫，与迁移 007 同一处理。历史兼容 fixture 会声称某个版本却不含该版本应有的全部表（v1 fixture 只有 `product_preferences`），对不存在的表建索引会让整次升级失败。索引是纯派生状态，走到这里还没有该表的库本来就没东西可索引。 + +> 附带修复：`schema_newer_than_v14_is_rejected_without_rollback` 里的"未来版本"从字面量 15 改成 `CURRENT_SCHEMA_VERSION + 1`，并改名为 `a_schema_newer_than_this_build_is_rejected_without_rollback`。本期把当前版本推到 15，这个测试原本会变成"断言当前版本被拒绝"——加迁移的人会先看到它失败，改完之后它就再也测不到东西了。 + +> 诚实性说明：p95 那条验收项是预算检查，不是分页设计的证明。实测确认它**抓不到**两件事：把排序改回去只让单页贵约五成（远在任何能在共享机器上稳定通过的阈值之内）；而且排序形态下页延迟**同样**与深度无关（排的是单个 rank 组，组大小不随翻到多深而变），所以"深页不比浅页贵"的比值断言也分不开两种形态。真正的保证是查询计划测试。这一点已写进测试的文档注释，比值只打印不断言。 + +--- + +##
