+# PR review runner
+
+**TL;DR:** run this image on a dedicated server runner restricted to the
+trusted review workflow. It installs the project's AIDD version with `npx`,
+reads the submitted Git diff and PR discussion, then publishes through the
+workflow. Without a manifest it uses `latest` and reports the missing plugin
+inventory.
+
+Only plugins from the trusted AIDD catalog are installed. Other recorded
+sources are reported as unavailable, and installed plugin versions may differ
+from the manifest because the remote catalog is current.
+
+Set these repository variables before enabling the workflows:
+
+- `OPENCODE_REVIEWER_ID`: numeric GitHub user ID allowed to submit reviews and
+  invoke `/opencode`. A missing or invalid ID authorizes nobody. Look it up
+  with `gh api users/USERNAME --jq .id`.
+- `AIDD_REVIEW_ENABLED_AT`: start timestamp in UTC, `YYYY-MM-DDTHH:MM:SSZ`.
+- `OPENCODE_BASE_BRANCH`: optional base branch for issue-created PRs; defaults
+  to the repository's default branch.
+- `OPENCODE_REVIEW_MODEL` and `OPENCODE_AGENT_MODEL`: optional OpenCode model
+  identifiers. Defaults are `openai/gpt-6.1-terra#medium` and
+  `opencode-go/beam-free`, respectively.
+
+Configure the `AIDD_BOT_APP_ID` and `AIDD_BOT_PRIVATE_KEY` secrets for the
+GitHub App. The `/opencode` workflow also requires `OPENCODE_API_KEY` and a
+model available through that credential.
+
+```sh
+docker build -f docker/aidd-opencode/runner/Dockerfile -t aidd-review-runner:local .
+docker volume create aidd-review-oauth
+```
+
+Authenticate the chosen provider in a temporary container using this volume.
+Use a provider-supported device code or a protected callback tunnel if the
+browser is on another machine. Do not expose the host network to the runner.
+OpenCode's [provider documentation](https://dev.opencode.ai/v2/docs/cli/providers/)
+describes the available login methods (read 2026-11-07):
+
+```sh
+: "${OPENCODE_PROVIDER:?Set OPENCODE_PROVIDER to your OpenCode provider}"
+docker run --rm -it --user reviewer -e HOME=/home/aidd \
+  -v aidd-review-oauth:/home/aidd/.local/share/opencode \
+  --entrypoint opencode aidd-review-runner:local --standalone auth login "$OPENCODE_PROVIDER"
+```
+
+This deployment requires a GitHub organization: its runner group must be
+limited to this repository and its review workflow on the default branch.
+Personal-account repositories need a different isolation design; using an
+unrestricted self-hosted runner on a public repository is unsafe. The
+[GitHub runner group documentation](https://docs.github.com/en/actions/how-tos/manage-runners/self-hosted-runners/manage-access)
+describes this restriction (read 2026-11-07).
+
+Create an `aidd-opencode-review` group with those restrictions. Use the
+organization name in `AIDD_RUNNER_ORG`. Register the container without a
+Docker socket or host data:
+
+```sh
+docker run -d --name aidd-review --restart unless-stopped \
+  --cap-drop ALL --cap-add SETUID --cap-add SETGID --cap-add CHOWN \
+  --cap-add AUDIT_WRITE --cap-add DAC_OVERRIDE --cap-add KILL \
+  -v aidd-review-oauth:/home/aidd/.local/share/opencode \
+  --entrypoint /bin/sh aidd-review-runner:local -c \
+    'while [ ! -f .configured ]; do sleep 1; done; exec /opt/aidd/runner'
+: "${AIDD_RUNNER_ORG:?Set AIDD_RUNNER_ORG to your GitHub organization}"
+gh api --method POST "orgs/$AIDD_RUNNER_ORG/actions/runners/registration-token" --jq .token |
+  docker exec -i --env AIDD_RUNNER_ORG="$AIDD_RUNNER_ORG" aidd-review sh -c '
+    set -eu; read -r token; umask 077
+    ./config.sh --unattended --url "https://github.com/$AIDD_RUNNER_ORG" \
+      --token "$token" --name aidd-review --runnergroup aidd-opencode-review
+    touch .configured
+  '
+```
+
+Rebuild and replace the image when its trusted runtime files change. The
+reviewer has a repository-scoped read token; only the workflow receives the
+separate write token. The container and separate user reduce exposure but do
+not eliminate prompt-injection or container-escape risks.
