## Modified Files

### Final active diff for S8-owned files only

docs/protocols/closed_loop_protocol.md
```

### Shared worktree note

The repository worktree still contains many non-S8 changes from other parallel
sessions. The list above is the S8-scoped diff only.

## Changes Summary

- `.planning/STATE.md`
  Added the prepared `v3.0` milestone `3-Mode Runtime Alignment` and updated
  roadmap narrative so future planning language matches the canonical 3-mode
  system.
- `.planning/phases/165.2/PLAN.md`
  Rewrote Phase 165.2 around `explore` / `learn` / `implement`, updated
  escalation triggers, acceptance checks, and preserved legacy names only in a
  dedicated migration note.
- `docs/AUDIT_REPORT_ALIGNMENT.md`
  Recorded the 4-mode -> 3-mode migration and clarified that promotion is an
  operation within `learn` / `implement`, not a standalone mode.
- `docs/EXECUTION_PLAN.md`
  Updated A1/A3 progress, inserted mode refactoring into priority order, and
  recorded the current testing baseline.
- `docs/protocols/L4_validation_protocol.md`
  Replaced `verify mode` language with `learn`-aligned validation wording.
- `docs/protocols/brain_protocol.md`
  Removed standalone `verify` / `promote` mode framing and documented them as
  loop-triggered operations; set the default mode to `explore`.
- `docs/protocols/closed_loop_protocol.md`
  Updated validation-entry wording to refer to `learn` / `implement` activity
  rather than `verify mode`.

## Conflict Check

- 越界文件: 无活动越界 diff。此前短暂触碰过
  `docs/protocols/action_queue_protocol.md` 与
  `docs/protocols/mode_envelope_protocol.md`，已回滚
- 冲突文件: 无。当前 S8 保留 diff 仅覆盖协调文件中 S8 owns 的 7 个文件
- 模式名一致性: 是。S8 文件使用 `explore` / `learn` / `implement`；旧模式名仅保留在迁移说明或审计记录中

## Legacy Mode Scan

### Residual old mode names used as mode constants in `docs/protocols/`

- `docs/protocols/action_queue_protocol.md:83`
  `If the mode is discussion, no verify or promote actions are queued.`
  This is a real leftover legacy mode-constant usage.
  It is **not** S8-owned, so S8 did not modify it.

### Old mode names found inside S8-owned files

- `docs/AUDIT_REPORT_ALIGNMENT.md`
  Legacy names appear only in the migration record
  (`discussion -> explore`, `verify -> learn`, `promote -> implement`).
- `.planning/phases/165.2/PLAN.md`
  Legacy names appear only in the dedicated `Migration Note`.
- `docs/protocols/brain_protocol.md`
  `promote` appears as an operation verb (`promote to L2`), not as a mode
  constant.
- `docs/EXECUTION_PLAN.md`
  `Verify` appears as an English verb in checklist text, not as a runtime mode.

## Consistency Check

Reference checked:
- `research/knowledge-hub/knowledge_hub/mode_registry.py`
  `VALID_RUNTIME_MODES = {"explore", "learn", "implement"}`

Conclusion:
- S8-owned documents are consistent with the runtime source of truth.
- S8-owned documents describe a 3-mode system:
  `explore`, `learn`, `implement`.
- They also consistently state that validation and promotion are operations,
  not standalone modes.
- One legacy non-S8 protocol file (`action_queue_protocol.md`) still needs
  follow-up by its owner to fully align `docs/protocols/`.

## Test Results

未运行代码测试。

本轮执行的验证是文档一致性与 ownership 检查：
- `rg -n --glob '*.md' 'discussion' docs/protocols`
- `rg -n --glob '*.md' '\\bverify\\b' docs/protocols`
- `rg -n --glob '*.md' '\\bpromote\\b' docs/protocols`
- S8-owned 文件逐项 `rg` 检查
- `git diff --name-only -- <S8 files>`
- `git diff --stat -- <S8 files>`

## Issues

- 共享工作树中还有其他 session 的大量改动，所以全仓 `git diff` 不能直接代表 S8 的边界，必须用 path-restricted diff 判断。
- `docs/protocols/action_queue_protocol.md` 仍有旧 mode constant，但该文件不属于 S8，不能由 S8 直接修复。

## Next Steps

- S8 范围内的文档与规划已经和 `mode_registry.py` 的 3-mode 系统一致。
- 若继续推进，应通知对应 owner 修复
  `docs/protocols/action_queue_protocol.md:83`。
- 除非你要求进一步调整，否则 S8 不再修改非拥有文件，也不触碰代码文件。
