fix(session-ui): count patched files in tool summaries

Grouped tool summaries used the raw tool-call count, so repeated patch calls reported the number of invocations instead of the distinct files changed. Derive the count from successful patch metadata while keeping the existing fallback for other tools.

 Run `LLMClient.stream(request)` instead of `generate` when you want incremental `LLMEvent`s. The event stream is provider-neutral — same shape across OpenAI Chat, OpenAI Responses, Anthropic Messages, Gemini, Bedrock Converse, and any OpenAI-compatible deployment.
 
+## Alibaba Cloud Model Studio
+
+`Alibaba` provides standard Model Studio inference. Configure a region explicitly, then select
+Chat Completions (`.model` or `.chat`), Anthropic-compatible Messages (`.messages`), or OpenAI-compatible
+Responses (`.responses`). These routes use HTTP/SSE.
+
+```ts
+import { LLM } from "@opencode/ai"
+import { Alibaba } from "@opencode/ai/providers"
+
+const alibaba = Alibaba.configure({
+  region: "ap-southeast-1", // Singapore
+  apiKey: process.env.DASHSCOPE_API_KEY,
+  // workspaceID: "llm-your-workspace", // use a workspace-dedicated endpoint
+})
+
+const request = LLM.request({
+  model: alibaba.model("qwen3.8-max"),
+  prompt: "Explain this design.",
+  providerOptions: { reasoningEffort: "medium" },
+})
+```
+
+### Regions and credentials
+
+| Region              | `region`         | Shared host when `workspaceID` is omitted |
+| ------------------- | ---------------- | ----------------------------------------- |
+| Singapore           | `ap-southeast-1` | `dashscope-intl.aliyuncs.com`             |
+| China (Beijing)     | `cn-beijing`     | `dashscope.aliyuncs.com`                  |
+| China (Hong Kong)   | `cn-hongkong`    | `cn-hongkong.dashscope.aliyuncs.com`      |
+| US (Virginia)       | `us-east-1`      | `dashscope-us.aliyuncs.com`               |
+| Germany (Frankfurt) | `eu-central-1`   | Supply `workspaceID` or `baseURL`         |
+| Japan (Tokyo)       | `ap-northeast-1` | Supply `workspaceID` or `baseURL`         |
+
+With `workspaceID`, the host is `{workspaceID}.{region}.maas.aliyuncs.com`. A complete `baseURL`
+overrides regional setup, including the API prefix: `/compatible-mode/v1` for Chat/Responses,
+or `/apps/anthropic/v1` for Messages. The selector appends its operation path.
+
+Keys and model availability are region-specific. Auth resolves from explicit `auth` or `apiKey`,
+then `DASHSCOPE_API_KEY`, then `ALIBABA_API_KEY`.
+
+The access region and inference scope differ: Virginia's `-us` model IDs request US-only inference;
+some regions select scope through their workspace. Model IDs pass through unchanged.
+Alibaba's [regional guide](https://www.alibabacloud.com/help/en/model-studio/regions) and
+[base URL table](https://www.alibabacloud.com/help/en/model-studio/base-url) disagree about Virginia's
+shared host; the entry above follows the base URL table. Dedicated hosts can be copied from the console.
+
+### Native options
+
+- **Chat:** `reasoningEffort` → `reasoning_effort`, `enableThinking` → `enable_thinking`,
+  `thinkingBudget` → `thinking_budget`, and `preserveThinking` → `preserve_thinking`.
+  Replay complete `response.message` values to retain `reasoning_content` separately from answer text.
+  Qwen 3.8 defaults to preserving thinking; older models have different defaults.
+  Additional options include `toolStream`, `parallelToolCalls`, `repetitionPenalty`, `responseFormat`,
+  `enableSearch`, and native `searchOptions`. `generation.topK` lowers to `top_k`.
+  `clearThinking` is a hosted GLM control, and `thinking.type` is available for hosted MiniMax models.
+- **Messages:** `effort` → `output_config.effort`. `thinking.type` accepts enabled/disabled with an
+  optional `budgetTokens` (or native `budget_tokens`). `outputConfig.format` accepts a JSON schema.
+  Model Studio's empty thinking signatures are accepted; supplied signatures are replayed unchanged.
+- **Responses:** `reasoningEffort` → `reasoning.effort`, plus `enableThinking`, `store`,
+  `previousResponseId`, and `conversation`. Omitted `store` retains the API's default (`true`);
+  set it to `false` for client-managed history. `previousResponseId` requires a stored response.
+  Hosted tools are `Alibaba.webSearch()`, `Alibaba.webExtractor()`, and `Alibaba.codeInterpreter()`.
+  Web extraction is used together with web search. Hosted calls/results carry `providerExecuted: true`.
+
+Omitted options preserve provider defaults. Effort values pass through unchanged and accept future
+strings. Qwen 3.8 Chat rejects requests combining a thinking budget with effort.
+
+Package entrypoints are `@opencode/ai/providers/alibaba`, `alibaba/chat`, `alibaba/messages`,
+and `alibaba/responses`. Live recordings cover all three APIs in Singapore; regional URL construction
+is unit-tested for all six regions.
+
 ## Z.AI
 
 `ZAI` uses the standard API. Chat Completions is the default language-model API;

+# Session-export load benchmark
+
+Replay an exported session against a production app build. The two cases compare the default Compact preset with every category ungrouped and details still collapsed.
+
+From `packages/app` in PowerShell:
+
+```powershell
+$env:PLAYWRIGHT_BUILD = '1'
+$env:PLAYWRIGHT_BASE_URL = 'http://127.0.0.1:4398' # Existing production preview
+$env:LAGGY_SESSION_FILE = 'C:\path\session.json'
+$env:LAGGY_SESSION_OUTPUT = 'C:\tmp\opencode\session-load'
+$env:LAGGY_SESSION_HISTORY = 'paged' # Or 'full' to supply all exported history
+bun x playwright test --config e2e/performance/playwright.config.ts timeline/laggy-session-benchmark.spec.ts --repeat-each=20 --workers=1 --retries=0
+bun e2e/performance/timeline/laggy-session-report.ts $env:LAGGY_SESSION_OUTPUT
+```
+
+Each test uses a fresh browser context and measures one cold load, switches back to the source session, then measures one warm load. Repetitions therefore interleave `cold → warm` pairs rather than collecting separate cold and warm batches. There are no discarded warm-up switches. The warm member of every pair must issue zero message requests. Each pair is saved in a separate JSON file; compare paired differences as well as the cold and warm distributions when system load varies.
+
+The report writes `summary.json` and prints the median, p95, maximum, and median paired cold-minus-warm difference. It rejects incomplete or cold-only records instead of mixing them into paired results.
+
+`--repeat-each=20` collects 20 pairs per grouping mode. `LAGGY_SESSION_COLD_ONLY=1` remains available for focused cold profiling. Screenshots are taken after a pair finishes, not between its measurements.
+
+The app shell, source session, model control, and fonts are ready before the timed action. These measurements cover session entry, not application startup. `firstCorrectObservedMs` begins at mousedown and ends when the destination is visible at its expected bottom position, including Compact's automatic history fill. `stableObservedMs` includes three-observation confirmation and must not be treated as additional rendering time.
+
+Set `OPENCODE_PERFORMANCE_TRACE_DIR` for Chrome traces. `LAGGY_TRACE_ITERATION=0` traces the cold load; the default (`1`) traces the warm member of the pair. Profile separately from timing runs.
+
+`LAGGY_HTTP=1` disables route interception for an external HTTP replay server containing the same export and source fixture. Keep direct HTTP and Playwright-routed cold series separate: routing adds transport overhead. Raw samples, mode settings, viewport, browser version, and screenshots are retained in the output directory. The export itself is not copied into the repository.
