Problem

The edge container Dockerfile is based on caddy:alpine. The claude binary is dynamically linked against glibc. Alpine uses musl libc, so claude fails with:

sh: /usr/local/bin/claude: not found

Installing gcompat doesn't help — the binary uses relocation types that gcompat doesn't support:

Error relocating /usr/local/bin/claude: unsupported relocation type 37

This blocks the supervisor integration (#344) — the supervisor needs claude -p to run in the edge container.

Fix

Change the edge Dockerfile base image from caddy:alpine to a Debian-based image with Caddy installed:

FROM caddy:latest

caddy:latest (without the alpine suffix) is Debian-based. Alternatively:

FROM debian:bookworm-slim
RUN apt-get update && apt-get install -y caddy bash jq curl git docker.io && rm -rf /var/lib/apt/lists/*

The first option is simpler and stays consistent with the Caddy project's official images.

Affected files

docker/edge/Dockerfile (change FROM caddy:alpine to FROM caddy:latest)

Acceptance criteria

claude --version works inside the edge container
Caddy still runs correctly
docker-cli still available
Supervisor can run claude -p for health reasoning
