 - If package `exports` exists, loader only resolves `./tui` or `./server`; it never falls back to `exports["."]`.
 - For npm package specs, TUI does not use `package.json` `main` as a fallback entry.
 - `package.json` `main` is only used for server plugin entrypoint resolution.
+- If a configured plugin has no target-specific entrypoint, it is skipped with a warning (not a load failure).
 - If a package supports both server and TUI, use separate files and package `exports` (`./server` and `./tui`) so each target resolves to a target-only module.
 - File/path plugins must export a non-empty `id`.
 - npm plugins may omit `id`; package `name` is used.

 - `patchPluginConfig` returns structured result unions (`ok`, `code`, fields by error kind) instead of custom thrown errors.
 - `patchPluginConfig` serializes per-target config writes with `Flock.acquire(...)`.
 - `patchPluginConfig` uses targeted `jsonc-parser` edits, so existing JSONC comments are preserved when plugin entries are added or replaced.
 - npm plugin package installs are executed with `--ignore-scripts`, so package `install` / `postinstall` lifecycle scripts are not run.

 - Without `--force`, an already-configured npm package name is a no-op.

 - `api.plugins.install(spec, { global? })` runs install -> manifest read -> config patch using the same helper flow as CLI install.
 - `api.plugins.install(...)` returns either `{ ok: false, message, missing? }` or `{ ok: true, dir, tui }`.
 - `api.plugins.install(...)` does not load plugins into the current session. Call `api.plugins.add(spec)` to load after install.
-- For packages that declare a tuple `tui` target in `oc-plugin`, `api.plugins.install(...)` stages those tuple options so a following `api.plugins.add(spec)` uses them.
 - If activation fails, the plugin can remain `enabled=true` and `active=false`.
 - `api.lifecycle.signal` is aborted before cleanup runs.
 - `api.lifecycle.onDispose(fn)` registers cleanup and returns an unregister function.
