 ## Consequences
 
-Configs with `mode: code` and preset ids `code` are unsupported on this build. The session-persistent vocabulary still says `tool/code-dispatch*`, `tools-code-mode`, and `:code:`, so existing session logs load unchanged and no `SESSION_FORMAT_VERSION` bump is needed yet. The stacked persistence PR renames that vocabulary and is blocked until the v0→v1 migration lands with it (the version mechanics are the [session-event-vocabulary note](../simplification/2026-08-25-fail-closed-session-event-vocabulary.md)). Keyless snapshot refreshes carry this PR's vocabulary; the persistence PR refreshes the dispatch-bearing fixtures. The shipped decision this note renames is [the PTC foundation note](../feature/2026-06-15-ptc.md).

 ## 后果
 
-配置中写 `mode: code`、预设 id 为 `code`，在本构建上不再受支持。会话持久词汇仍为 `tool/code-dispatch*`、`tools-code-mode` 与 `:code:`，因此既有会话日志照常读取，无需 `SESSION_FORMAT_VERSION` 提升。堆叠的持久化 PR 负责重命名该词汇，并被阻塞到 v0→v1 迁移与其一同落地（版本机制见 [session event 词汇 Note](../simplification/2026-08-25-fail-closed-session-event-vocabulary.zh.md)）。无密钥的 snapshot refresh 携带本 PR 的词汇；持久化 PR 刷新包含分发的夹具。本 Note 所更名的已发布决策是 [PTC 基础 Note](../feature/2026-06-15-ptc.zh.md)。

 - ESM everywhere (`"type": "module"`). Use package names across packages and `.ts` in local relative imports. Config subprocesses run built `lib/` under plain Node; source regressions use their declared launcher ([testing policy](docs/testing.md#test-subprocess-launch-modes)). The `dsh` CLI source launch runs through tsx's ESM-only hook (`node --import tsx/esm`); modules it reaches must stay ESM (no CJS-only exports) — Node's native TypeScript modes are unavailable across the engines range ([source-launch contract](.agents/notes/implemented/architecture/2026-07-29-dsh-source-launch-tsx-esm.md)). Raw/Web `cordis.yml` bare plugins must appear in their resolver manifest's `dependencies`; `verify-cordis-config` enforces it.
 - **Registrations are effects**: every contribution goes through `ctx.effect()` / `ctx.on()`; a registry's `register()` returns the disposer.
 - **Runtime invariants assert owned relationships.** Check authoritative event streams or mutable data, not service or method presence, plugin metadata or effects, or fixed pure examples. Without a plausible relationship, an explained empty companion is correct ([package invariant rules](packages/AGENTS.md)).
-- **Typed events use declaration merging** and merge-extensible maps. Event JSDoc needs `@mode` and payload `@param`; scoped keys absent from payloads need `@dshScopeScan unsupported`. Public service methods document parameters and non-void returns. A `SessionEventMap` member is required-on-read by default — builds that do not know its type refuse the log unless the event carries the envelope's `ignorable: true`; only structural format changes bump `SESSION_FORMAT_VERSION` ([mechanism](.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md)).

 - **Waterfall listeners MUST call `next()`** to delegate; returning without it short-circuits the chain ([semantics](docs/cordis-primer.md#cordis-waterfall-semantics)).
 - **Model-visible ⟺ logged**: anything that reaches a model request must be reconstructable from the session log; a new model-visible input requires a session event.
