 ## Dependency management
 
-- **Always pin versions** in the Dockerfile `npm install` command (e.g. `opencode-ai@1.16.2 n2-soul@9.0.9`). Never leave packages unpinned.
+- **Always pin versions** in the Dockerfile `npm install` command (e.g. `@opencode/cli@2.0.32 n2-soul@9.0.9`). Never leave packages unpinned.
 - **Update renovate customManagers** when adding, removing, or renaming a dependency tracked in the Dockerfile. Each pinned package must have a corresponding `customManager` entry in `renovate.json` with a regex `matchStrings` pattern that captures the version. If a dependency is added without a renovate entry, Renovatebot will not open automated PRs for it.
 - **apt packages** (apt-get install lines in Dockerfile) and **COPY --from** image references are not currently tracked by Renovate. Pinning these manually is acceptable for now but adding renovate managers for them is encouraged.
 
 ## Dockerfile conventions
 
-- **Base image**: `node:24` — Debian-based Node.js image (not Alpine, needed for apt packages).
-- **Install**: `npm i -g opencode-ai@<version> n2-soul@<version>` — installs OpenCode and Soul globally, both pinned.
+- **Base image**: `node:26-trixie` — Debian-based Node.js image (not Alpine) so that downstream images can still use `apt-get` and Node-based MCP servers keep working.
+- **Install**: `npm i -g @opencode/cli@<version> n2-soul@<version>` — installs OpenCode 2 and Soul globally, both pinned. `@opencode/cli` replaced `opencode-ai` as the published package in OpenCode 2; `--allow-scripts=@opencode/cli` is required for its `postinstall` to select the native binary.
 - **Version check**: `RUN opencode --version` after install to validate the build and record the installed version in build logs.
 - **Dedicated user**: a non-root `opencode` user and group are created with `groupadd`/`useradd` (UID/GID 1000). All runtime steps run as this user.
 - **Cluster tooling**: `kubectl` is copied from the official `registry.k8s.io/kubectl` image (multi-stage COPY).
-- **Entrypoint**: `["opencode"]` — arguments are passed at runtime (e.g. `serve`).
+- **Entrypoint**: `["opencode"]` — arguments are passed at runtime; `serve` starts the headless server. Bare `opencode` opens the TUI, so the server is always invoked explicitly.
+
+## OpenCode 2 notes
+
+- The npm package is `@opencode/cli` (bins `opencode` and `opencode2`); `opencode-ai` stops at 1.19.x and must not come back.
+- `opencode attach` no longer exists: point a client at a server with `opencode --server <url>` (after the subcommand when one is given). `opencode-attach` wraps this.
+- The server always authenticates: username is fixed to `opencode`, password comes from `OPENCODE_SERVER_PASSWORD` or `OPENCODE_PASSWORD`, and a random one is generated and logged when neither is set.
+- The v1 REST API was replaced (`/global/health` is gone, every route now lives under `/api/*` and requires auth). Any client calling the v1 API — e.g. `perso/opencode-dispatch` — must be migrated separately.
