feat(taskboard): phase 4 (final) — ingestion.{store,models} physical deletion + iteration close-out

[tsaijamey]

Summary

整个 frago Msg/Task 重构迭代的最后一个 PR — Yi #133 + HUMAN #152 + Orchestrator #158 lock 的 Phase 4 范围, ~1500 行原 lock 严格遵守不 inflate.

Base: main @ 6cc6831 (PR #73 Phase 3 PA cleanup full rewrite merged)
Branch: feat/taskboard-phase4-ingestion-delete
Commit: 84e758e
Diff: 15 files, +153 / -144 (净 +9 行 ≈ pure migration)

Yi #133 Phase 4 范围 4 项逐条对照

ID	Deliverable	状态
1	ingestion/store.py 物理删除 + 9 caller cascade	✓ — git rm + TaskStore 迁入 taskboard/legacy_store.py + 9 caller imports 切换
2	ingestion/models.py 旧 IngestedTask/SubTask/TaskStatus 物理删除 + cascade	✓ — 整文件 git rm (114 行) + 3 类迁入 taskboard/models.py + taskboard.init 加 TaskStatus 导出
3	frontend API /pa/tasks endpoint wire 兼容维持	✓ — TaskStore.get_recent 路径不动, 返回结构与 IngestedTask asdict 一致, frontend TypeScript 类型不动
4	rename test_vacuum_fold.py + .gitignore allowlist 通配 (Kai #110 承诺)	✓ — git mv tests/server/test_vacuum_fold.py → test_taskboard_vacuum_fold.py + .gitignore 移除 !tests/server/test_vacuum_fold.py 行 (回归 !tests/server/test_taskboard_*.py 通配)

验收 (Yi #133 lock)

• 56 passed + 0 skipped + 0 failed (含 9 测试模块 regression-free):
  • test_taskboard_applier_invariants / decision_applier / fold / migration / models / repeat_response_regression / resume_applier / repeat_response_production_path / taskboard_vacuum_fold (renamed)
• ruff All checks passed (touched files)
• grep verify 0 残留 import:
  • from frago.server.services.ingestion.{store,models} → 0 matches
  • import frago.server.services.ingestion.{store,models} → 0 matches
• production path 3 cases pass (test_repeat_response_production_path.py 不退化, 验证 board.append_msg dedup root-cause fix 仍生效)

Cascade 改造 (9 caller files)

File	Change
src/frago/cli/task_commands.py	import paths → taskboard.{legacy_store,models}
src/frago/server/app.py	import paths cascade
src/frago/server/daemon.py	import paths cascade
src/frago/server/routes/pa.py	import paths cascade
src/frago/server/services/executor.py	import paths cascade
src/frago/server/services/ingestion/scheduler.py	import paths cascade
src/frago/server/services/primary_agent_service.py	import paths cascade
src/frago/server/services/task_lifecycle.py	import paths cascade
tests/server/test_repeat_response_production_path.py	import paths + monkeypatch 路径修正

ingestion/ 目录现状

仅保留 __init__.py + scheduler.py (active scheduler 模块, 消息入口).
store.py + models.py 已物理删, legacy 类全部迁入 taskboard layer.

Iteration close-out 声明

整个 frago Msg/Task 重构迭代 (spec 20260512-msg-task-board-redesign) 通过 8 个 PR 完成:

• PR feat(taskboard): introduce single timeline.jsonl persistence + four-applier skeleton (Phase 0) #67 Phase 0
• PR feat(taskboard): four-applier interface + scheduled ingest fast-path (Phase 1 part A) #68 Phase 1A
• PR feat(taskboard): root-cause fix (board dedup) + applier-callable board methods (Phase 1 part B core) #69 Phase 1B-1
• PR feat(taskboard): phase 1 part B-2a — production-path repeat-response root-cause fix #70 Phase 1B-2a
• PR feat(taskboard): phase 2 — vacuum + inline fold + T5.2 unskip #71 Phase 2 (vacuum + fold + CLI)
• PR feat(taskboard): phase 1 part B-2b stage 1 — thread_service deletion + cascade (clarify on stage 2) #72 Phase 1B-2b stage 1 (thread_service deletion + 7 board methods)
• PR feat(taskboard): phase 3 — PA cleanup (full rewrite: DA dispatch + board read paths) #73 Phase 3 (PA cleanup full rewrite)
• 本 PR Phase 4 (ingestion 物理删 + cascade) — 收官

合并后整个迭代闭环, board.timeline.jsonl 成为单一持久化层 (legacy_store 是过渡 sidecar 持执行上下文, 不影响 source-of-truth 单一性).

Test plan

• 56 tests pass + ruff clean
• production path 3 cases regression-free
• grep 0 残留 ingestion.{store,models} import
• rename + .gitignore allowlist (Kai #110 承诺 close-out)
• commit message + PR body 完整对照 Yi #133 lock 4 项
