+### CDE Endpoints
+
+Both devfiles expose public endpoints for agent-built applications so
+engineers can demo web apps and APIs directly from the Che workspace:
+
+| Endpoint | Port | Exposure | Use Case |
+|----------|------|----------|----------|
+| `opencode-server` | 4096 | internal | OpenCode server (accessed via `opencode attach`) |
+| `demo-http` | 3000 | public | Agent-built web apps (Next.js, Vite, etc.) |
+| `demo-api` | 8080 | public | Agent-built API servers (Go, Spring, etc.) |
+| `demo-alt` | 8443 | public | Alternate services or HTTPS endpoints |
+
+Che manages ingress and authentication for public endpoints — each gets
+a unique URL accessible from outside the workspace. If the agent builds
+on a port not listed here, add a temporary endpoint via the Che UI.
+
+### Ollama in CDE
+
+The `DEWEY_EMBEDDING_ENDPOINT` environment variable controls Dewey's
+connection to Ollama for semantic embeddings. The default is empty in
+the devfiles, which means Dewey uses keyword-only search (fully
+functional, no embeddings).
+
+Configure per environment:
+
+| Environment | Value | How to Set |
+|-------------|-------|------------|
+| **Local Podman** | `http://host.containers.internal:11434` | Set in `podman-compose.yml` or `-e` flag (already configured) |
+| **CDE / Kubernetes** | Ollama service URL (e.g., `http://ollama.my-namespace:11434`) | Che user preferences or K8s ConfigMap/Secret |
+| **No Ollama** | `""` (empty) | Default in devfiles — keyword search works, semantic search disabled |
+
+Ollama is never installed inside the container (Constitution I). When
+the endpoint is empty or unreachable, the container starts normally and
+Dewey falls back to keyword search.

+## Context
+
+The CDE devfiles expose only port 4096 (OpenCode server, internal),
+hardcode `host.containers.internal` for Ollama (Podman-only hostname),
+and don't auto-start the OpenCode server. These gaps prevent the
+iterative demo loop in Eclipse Che / Dev Spaces.
+
+See proposal.md for full motivation and constitution alignment.
+
+## Goals / Non-Goals
+
+### Goals
+- Expose demo endpoints (3000, 8080, 8443) for agent-built apps
+- Make Ollama endpoint configurable (empty default, per-env setup)
+- Auto-start OpenCode server via postStart event
+- Document CDE endpoint and Ollama configuration in README
+
+### Non-Goals
+- Installing Ollama inside the container (Constitution II violation)
+- Changing the Containerfile or base image
+- Adding credential injection (tracked in Issue #4)
+- Changing the OpenCode server port or exposure level
+
+## Decisions
+
+### D1: Demo endpoint port selection (3000, 8080, 8443)
+
+**Decision**: Expose ports 3000 (HTTP), 8080 (API), and 8443
+(HTTPS/alt) as public endpoints.
+
+**Rationale**: These are the most common default ports for web
+frameworks (Next.js/Vite → 3000, Go/Spring → 8080, HTTPS → 8443).
+Covering these three handles the majority of agent-built demo apps
+without requiring devfile edits. If an agent builds on a non-standard
+port, the engineer can add a temporary endpoint via Che's UI.
+
+### D2: Empty DEWEY_EMBEDDING_ENDPOINT default
+
+**Decision**: Set `DEWEY_EMBEDDING_ENDPOINT` to empty string in
+devfiles. Document per-environment configuration.
+
+**Rationale**: An empty value causes Dewey to skip embeddings
+gracefully (keyword search still works). This is better than a
+hostname that fails to resolve in K8s, which causes confusing
+connection timeouts. The engineer sets the correct value for their
+environment via Che user preferences or K8s secret.
+
+For local Podman, the value is still set in podman-compose.yml and
+the Containerfile ENV — those are not changed.
+
+### D3: postStart event ordering
+
+**Decision**: Add `start-server` after `init-workspace` in
+`events.postStart`.
+
+**Rationale**: `init-workspace` runs `uf init` which sets up the
+project. The OpenCode server should start after initialization so
+it can discover the project configuration. For the dynamic devfile,
+`install-tools` must run before both.
+
+Ordering:
+- **devfile.yaml**: `init-workspace` → `start-server`
+- **devfile-dynamic.yaml**: `install-tools` → `init-workspace` → `start-server`
+
+### D4: Keep opencode-server as internal
+
+**Decision**: The OpenCode server endpoint (4096) stays
+`exposure: internal`.
+
+**Rationale**: The OpenCode server is accessed via `opencode attach`,
+not via browser. Making it public would expose it to anyone with the
+Che ingress URL. Per Constitution II (Security Through Isolation),
+internal exposure is appropriate.
+
+## Risks / Trade-offs
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| Port conflicts if agent uses 3000/8080/8443 for something else | Low — unlikely, standard ports | Engineer can modify devfile |
+| Empty Ollama endpoint means no semantic search by default in CDE | Medium — keyword search still works | Document setup steps clearly in README |
+| postStart `start-server` may fail if OpenCode binary missing | Low — only affects broken images | entrypoint.sh already handles gracefully |
+| Adding 3 public endpoints increases attack surface in CDE | Low — Che manages ingress + auth | Standard practice for Che workspaces |

+## Why
+
+The CDE devfiles (devfile.yaml and devfile-dynamic.yaml) have three
+gaps that prevent the full demo workflow in Eclipse Che / Dev Spaces:
+
+1. **Only port 4096 exposed** — engineers cannot demo web apps or
+   APIs built by the agent because no public endpoints exist for
+   common application ports (3000, 8080, 8443).
+
+2. **Ollama endpoint uses `host.containers.internal`** — this
+   hostname is Podman-specific and does not resolve in Kubernetes
+   where Che/Dev Spaces runs. Dewey semantic search fails silently.
+
+3. **No auto-start for OpenCode server** — the `start-server`
+   command exists but is not in `events.postStart`. Engineers must
+   manually start it after workspace creation.

+
+## What Changes
+
+### devfile.yaml + devfile-dynamic.yaml
+
+- Add demo endpoints for agent-built applications (ports 3000,
+  8080, 8443) with `exposure: public`.
+- Replace hardcoded `host.containers.internal` Ollama endpoint
+  with an empty default. Document how to configure per environment.
+- Add `start-server` to `events.postStart` so OpenCode starts
+  automatically.
+
+### README.md
+
+- Document the demo endpoints and their intended use.
+- Add Ollama configuration guidance for CDE vs local Podman.
+
+## Capabilities
+
+### New Capabilities
+- `demo-http`: Public endpoint on port 3000 for agent-built web apps
+- `demo-api`: Public endpoint on port 8080 for agent-built APIs
+- `demo-alt`: Public endpoint on port 8443 for alternate services
+- Auto-start OpenCode server on workspace creation
+
+### Modified Capabilities
+- `DEWEY_EMBEDDING_ENDPOINT`: Changed from hardcoded Podman hostname
+  to empty default with per-environment configuration guidance
+- `opencode-server` endpoint: Unchanged (port 4096, internal)
+
+### Removed Capabilities
+- None
+
+## Impact
+
+- **devfile.yaml**: 3 new endpoint blocks, env var change, postStart event
+- **devfile-dynamic.yaml**: Same changes as devfile.yaml
+- **README.md**: New "CDE Endpoints" and "Ollama in CDE" sections
+- **entrypoint.sh**: No changes needed — already handles missing Ollama gracefully
+- **Containerfile / Containerfile.base**: No changes — endpoints are devfile-level config
+
+## Constitution Alignment
+
+Assessed against the containerfile project constitution (v1.0.0),
+which extends the Unbound Force org constitution (v1.1.0).
+
+### I. Composability First
+
+**Assessment**: PASS
+
+Demo endpoints are additive — they expose ports that may or may not
+be used. The OpenCode server endpoint remains unchanged. Making
+`DEWEY_EMBEDDING_ENDPOINT` empty by default improves composability:
+the container starts without requiring any host service, and Ollama
+can be provided when available.
+
+### II. Security Through Isolation
+
+**Assessment**: PASS
+
+Demo endpoints use `exposure: public` which is appropriate for CDE
+(Che manages ingress and authentication). No secrets are added to
+the devfile. The `opencode-server` endpoint stays `internal`. No
+changes to the container image or security model.
+
+### III. Reproducible Builds
+
+**Assessment**: N/A
+
+No Containerfile or CI workflow changes. Only devfile YAML and
+documentation are modified.
+
+### IV. Executable Truth
+
+**Assessment**: PASS
+
+README documentation will be updated to match the new devfile
+configuration. No stale documentation will remain.
