Subject: [PATCH 1/6] fix(host): release v1.1.4 (fix snapshotEvents
 compatibility with dsh-session >= 0.1.2-rc.1)

- fix(host): adapt /usage route to use session.snapshotEvents() for dsh-session >= 0.1.2-rc.1 with fallback to legacy session.events (#7)
- test: add coverage for snapshotEvents() preference and fallback under /usage
- docs: update README and CHANGELOG to 1.1.4
- chore: bump version to 1.1.4 in package.json and package-lock.json

+## [1.1.4] - 2026-09-08
+
+### Fixed
+
+- **`dsh-session >= 0.1.2-rc.1` compatibility (snapshotEvents())** — [PR #7](https://github.com/Max-Samson/dsh-usage-chart/pull/7): `dsh-session` removed its public `events` property in `0.1.2-rc.1` (replaced by the `snapshotEvents()` method); the `/usage` route then threw `TypeError: events is not iterable`, which `dsh-host-webserver` wrapped as a bare `400` empty response, and the per-round chart disappeared (the client fell back to the empty observed-rounds path). Reproduced live on `dsh-session 0.1.2-rc.1`: `/usage?session=<loaded>` returned an empty `400` while `/usage?session=<unknown>` returned the plugin `404` JSON and folding the same log offline succeeded — confirming the crash was only the new runtime API shape. The host now reads events via capability detection — prefers `session.snapshotEvents()` when the function is present and falls back to the legacy `session.events ?? []` (so a missing API can never crash the route again). The vendored `SessionEventLike` type adds the `time` field (Unix epoch ms) and a `SessionHandle` shape (optional `events` + optional `snapshotEvents`) so `SessionStoreService.get()/list()` stay valid across both API generations. Verified against the upstream `deepseek-harness` source: `Session.events` was removed from `0.1.2-alpha.4` onward (official architecture note `2026-08-21-session-log-read-intent`); the installed `0.1.0-rc.6` still exposes `events`, so the fallback path remains covered.
+- **Test coverage for the new `snapshotEvents()` access path**: added `tests/rounds.test.mjs` → `/usage route prefers snapshotEvents() when the new API is present`, mocking a session handle that exposes only `snapshotEvents()` (its `get events()` throws, proving the route never reads the removed property), asserts `time` is consumed (duration/peak billing) and that `snapshotEvents()` wins when both APIs are present.

+## [1.1.4] - 2026-09-08
+
+### 修复
+
+- **适配 `dsh-session >= 0.1.2-rc.1`（改用 `snapshotEvents()`）**——[PR #7](https://github.com/Max-Samson/dsh-usage-chart/pull/7)：`dsh-session` 在 `0.1.2-rc.1` 移除了公开的 `events` 属性（改为 `snapshotEvents()` 方法）；`/usage` 路由随之抛 `TypeError: events is not iterable`，被 `dsh-host-webserver` 包装成裸 `400` 空响应，每轮图表消失（客户端回退到空的 observed-rounds 路径）。已在 `dsh-session 0.1.2-rc.1` 上实测复现：`/usage?session=<已加载会话>` 返回空 `400`、`/usage?session=<未知>` 返回插件 `404` JSON、离线折叠同一日志却成功——证明崩溃仅源于新版运行时 API 形状。宿主现在通过能力检测读取事件——`snapshotEvents` 为函数时优先调用它，否则回退到旧版 `session.events ?? []`（即便 API 缺失也绝不再导致路由崩溃）。同时为 vendored 的 `SessionEventLike` 类型补齐 `time` 字段（Unix epoch 毫秒），并新增 `SessionHandle` 形状（可选 `events` + 可选 `snapshotEvents`），使 `SessionStoreService.get()/list()` 在新旧两代 API 下均成立。已对照上游 `deepseek-harness` 源码核实：`Session.events` 自 `0.1.2-alpha.4` 起移除（官方架构笔记 `2026-08-21-session-log-read-intent`）；本机安装的 `0.1.0-rc.6` 仍暴露 `events`，因此回退分支持续有覆盖。
+- **为新的 `snapshotEvents()` 读取路径补充测试**：新增 `tests/rounds.test.mjs` → `/usage route prefers snapshotEvents() when the new API is present`，mock 一个只暴露 `snapshotEvents()` 的会话句柄（其 `get events()` 会抛错，证明路由绝不读取被移除的属性），断言 `time` 被正确消费（耗时/峰值计费），并验证同时暴露两者时优先使用 `snapshotEvents()`。

+### Changed
+
+- **DeepSeek official pricing update (2026-09-10) & `deepseek-flash` support** — [PR #8](https://github.com/Max-Samson/dsh-usage-chart/pull/8):
+  - **New `deepseek-flash` model pricing**: Updated builtin pricing according to the official DeepSeek pricing table (verified 2026-09-10). The new `deepseek-flash` rates are:
+    - **Off-peak** (Beijing Mon–Fri non-peak & weekends): CNY 1.0 / 0.02 / 4.0 per 1M tokens (cache-miss input / cache-hit input / output); USD 0.15 / 0.003 / 0.6 per 1M tokens.
+    - **Peak** (Beijing Mon–Fri 09:00–12:00 & 14:00–18:00): CNY 2.0 / 0.04 / 8.0 per 1M tokens; USD 0.30 / 0.006 / 1.2 per 1M tokens.
+  - **Backward compatibility for legacy model names**: `deepseek-v4-flash` and `deepseek-v4-flash-vision-exp` are mapped to `deepseek-flash` in `BUILTIN_PRICING` so historical session logs continue resolving without falling back to unknown-model estimates.
+  - **Fallback pricing**: Default unlisted model fallback (`FALLBACK_PRICING`) now points to the new `deepseek-flash` pricing.
+  - **Docs & test synchronization**: Updated custom `pricing.json` example in `README.md` and `README_ZH.md` (`verifiedAt: 1788998400000`), and aligned test cases across `tests/core.test.mjs`, `tests/pricing.test.mjs`, and `tests/rounds.test.mjs` (`BUILTIN_VERIFIED_AT` set to `2026-09-10T00:00:00Z`).

+- **同步 DeepSeek 官方最新调价（2026-09-10）与 `deepseek-flash` 适配**——[PR #8](https://github.com/Max-Samson/dsh-usage-chart/pull/8)：
+  - **新增 `deepseek-flash` 官方刊例价**：按 DeepSeek 官方 2026-09-10 最新调价更新内置定价表，`deepseek-flash` 刊例价全面下调：
+    - **空闲时段**（北京时间工作日非高峰与周末全天）：人民币 CNY 1.0 / 0.02 / 4.0 每 1M tokens（未命中输入 / 命中输入 / 输出）；美元 USD 0.15 / 0.003 / 0.6 每 1M tokens。
+    - **高峰时段**（北京时间工作日 09:00–12:00 与 14:00–18:00）：人民币 CNY 2.0 / 0.04 / 8.0 每 1M tokens；美元 USD 0.30 / 0.006 / 1.2 每 1M tokens。
+  - **历史模型标识平滑兼容**：将 `deepseek-v4-flash` 与 `deepseek-v4-flash-vision-exp` 指向 `deepseek-flash` 价格表，确保历史会话在重新加载与折叠时平滑解析，不被判定为未定价模型。
+  - **未收录模型回退**：未收录模型的默认保守估算回退（`FALLBACK_PRICING`）同步切换至新版 `deepseek-flash` 刊例价。
+  - **文档与测试同步**：更新 README 中的 `pricing.json` 自定义配置示例与核验时间戳（`verifiedAt: 1788998400000` 即 2026-09-10）；全量同步 core、pricing、rounds 单测断言与 `BUILTIN_VERIFIED_AT`。

Subject: [PATCH 4/6] fix(host): release the pricing file source with the
 fiber, not at apply time

ctx.effect(() => fileSource.dispose(), ...) calls dispose while the fiber is
being built and registers undefined as the disposer: the file source is dead
before its first read, so pricing.json is never applied and the change watcher
never fires. Return a disposer instead.

Test mocks now follow cordis semantics (run setup, keep the returned disposer,
release it in after()) and a /pricing route regression test covers the override
path - it fails against the old form.

+### Fixed
+
+- **Host pricing file source lifecycle (`pricing.json` override & change watcher)** — [PR #10](https://github.com/Max-Samson/dsh-usage-chart/pull/10):
+  - Fixed premature disposal of `filePricingSource` during plugin registration: `ctx.effect(() => fileSource.dispose(), ...)` called `dispose()` synchronously while building the fiber and registered `undefined` as the cleanup handler, aborting initial asynchronous file loading and disabling the file change watcher. Resolved by returning a disposer function: `ctx.effect(() => () => fileSource.dispose(), ...)`.
+  - Updated test mocks in `tests/core.test.mjs`, `tests/pricing.test.mjs`, and `tests/rounds.test.mjs` to properly track and execute Cordis effect disposers in `after()`.
+  - Added regression test covering the `/pricing` route with user `pricing.json` overrides enabled at startup.

+
+### 修复
+
+- **宿主自定义价格文件源生命周期早释问题（`pricing.json` 覆盖与变更监听）**——[PR #10](https://github.com/Max-Samson/dsh-usage-chart/pull/10)：
+  - **修复 `filePricingSource` 启动即被销毁的 Bug**：此前 `ctx.effect(() => fileSource.dispose(), ...)` 在挂载期立即执行了清理调用，导致文件数据源在首次异步读取完成前被截断关闭，致使用户配置的 `pricing.json` 覆盖及变更监听均无法生效。现已修正为返回高阶清理函数 `ctx.effect(() => () => fileSource.dispose(), ...)`，使文件源在 fiber 卸载时才被释放。
+  - **纠正单测 Cordis effect Mock 语义**：在 `tests/core.test.mjs`、`tests/pricing.test.mjs` 与 `tests/rounds.test.mjs` 中对齐 Cordis 真实生命周期契约，在 `after()` 中统一执行清理函数。
+  - **补充端到端回归用例**：新增 `/pricing route serves the user pricing.json override (file source survives startup)`，验证插件挂载自定义 `pricing.json` 时价格覆盖正常生效且来源正确标记为 `file`。

Subject: [PATCH 6/6] fix(client): anchor the fixed panel to its containing
 block

A position:fixed box is laid out against its containing block, not the viewport:
any ancestor with transform / filter / backdrop-filter / contain / container-type
takes that role. The maid-atelier skin blurs the dock children
([data-slot='conversation.composer.dock'] > *, backdrop-filter: blur(2px)), so
the popover was offset by the indicator row's own origin and flew off to the
right of the screen.

Look up the nearest containing block and convert the viewport anchor into its
coordinate space; also guard the clamp range on narrow windows.
