 - Local `main` ref may not exist; use `dev` or `origin/dev` for diffs.
 
+## Live V2 TUI Testing
+
+- Run `bun run dev:live` from a development worktree to test its TUI against the currently elected `opencode2` background server and live sessions.
+- Pass a directory after the script when needed, for example `bun run dev:live /path/to/project`.
+- The script discovers the server with `opencode2 service status`, injects its private local credential from `opencode2 service get password`, and uses the `next` TUI storage channel so tabs and other client-local state match the installed client.
+- Prefer `dev:live` over plain `bun run dev` for this workflow. An implicit managed-service connection may replace the live server when the worktree client version differs; explicit `--server` warns and continues without replacing it.
+
 ## Branch Names
 
 Use a short branch name of at most three words, separated by hyphens. Do not use slashes or type prefixes such as `feat/` or `fix/`.

 5. Azure is only a provider facade, not a full runtime replacement. Native Azure exists, but the catalog runner does not select it, and token auth/resource variants need review.
 6. Provider option typing is uneven. OpenAI, Anthropic, Gemini, Bedrock, and OpenRouter each expose a small typed subset plus raw HTTP overlays; this is useful but not equivalent to AI SDK provider option coverage.
 7. Structured output is not provider-native yet. `LLM.generateObject` still uses a synthetic tool strategy, while the future design expects native structured output where reliable and tool fallback where needed.

-/**
- * Tutorial: split global services from context-specific services.
- *
- * Use this pattern when part of the app should be constructed once at the app edge,
- * while another part should be cached per request/project/workspace key.
- *
- * In this example:
- * - Npm.Service is the global service. It is not keyed by request context and should
- *   be provided once by the application runtime.
- * - ConfigService is context-specific. It is built from a RequestContext key and is
- *   cached by LayerMap for that key.
- * - ConfigServiceMap.layer owns the cache. Provide it once globally, then each
- *   request can provide ConfigServiceMap.get(context) to select the right instance.
- *
- * Lifetime model:
- * - ConfigServiceMap.layer has the app/global lifetime and depends on Npm.Service.
- * - ConfigServiceMap.get(context) has the request/context lifetime and provides
- *   ConfigService for exactly that context key.
- * - The cached ConfigService entry stays alive while something is using it. Once idle,
- *   it remains cached for idleTimeToLive, then its scope is finalized.
- * - invalidate(context) removes the cache entry for future lookups. Active users keep
- *   running on the old instance; the next lookup can create a fresh instance.
- *
- * Key model:
- * - Keys can be strings, structs, classes, arrays, etc.
- * - Prefer primitive or immutable keys. Effect uses Hash / Equal semantics for cache
- *   lookup, so mutating an object after it has been used as a key is a bug.
