## Context
Review of the BeadBoard Dispatch wiring found that the claude-agent-service
Dockerfile's `COPY beads/metadata.json /workspace/.beads/metadata.json` and
`COPY agents/beads-task-runner.md /home/agent/.claude/agents/...` both land
on paths that are volume-mounted at runtime:
- `/workspace` → `claude-agent-workspace-encrypted` PVC (main.tf:394-398)
- `/home/agent/.claude` → `claude-home` emptyDir (main.tf:424-427)
Kubernetes mounts hide image-layer content at those paths, so the COPYs are
dead. The companion commit in `claude-agent-service` restages both files to
`/usr/share/agent-seed/` (an image-layer path that is never mounted).
Additionally, the beads-task-runner agent rails expect
`/workspace/scratch/<job_id>/` to exist, but nothing was creating it.
## Layout before / after
```
Before (dead COPYs):
image layer runtime (mounted volumes hide the files)
----------- -----------------------------------
/workspace/ <- hidden by PVC mount
.beads/
metadata.json <- UNREACHABLE
/home/agent/.claude/ <- hidden by emptyDir mount
agents/
beads-task-runner.md <- UNREACHABLE
After (init container seeds volumes at pod start):
image layer runtime
----------- ------------------------------------
/usr/share/agent-seed/
beads-metadata.json --+
beads-task-runner.md --+-> copied by seed-beads-agent init
container into the mounted volumes
on every pod start:
/workspace/.beads/metadata.json
/workspace/scratch/
/home/agent/.claude/agents/beads-task-runner.md
```
## What
### New init container: `seed-beads-agent`
- Positioned AFTER `git-init`, BEFORE the main container.
- Uses the same service image (`${local.image}:${local.image_tag}`) — the
seed files are baked in at `/usr/share/agent-seed/`.
- Runs as default uid 1000 (the PVCs are already chowned by `fix-perms`).
- Shell body:
mkdir -p /workspace/.beads /workspace/scratch /home/agent/.claude/agents
cp /usr/share/agent-seed/beads-metadata.json /workspace/.beads/metadata.json
cp /usr/share/agent-seed/beads-task-runner.md /home/agent/.claude/agents/beads-task-runner.md
- Mounts: `workspace` at `/workspace`, `claude-home` at `/home/agent/.claude`.
- Resources: 32Mi requests / 64Mi limits (matches `fix-perms`/`copy-claude-creds`).
### Formatting
- `terraform fmt -recursive` also normalised whitespace in the token-expiry
locals block and the CronJob container definition. No semantic change.
## What is NOT in this change
- No image tag bump. The Dockerfile refactor that produces the
`/usr/share/agent-seed/` path lands in the claude-agent-service repo
and will roll in on the next CI build. Until that build ships and the
tag is bumped in this file, the new init container will `cp` from a
path that doesn't exist yet — so do NOT apply this commit until the
corresponding image tag bump is ready. The commit is declarative prep.
- No changes to storage class, RBAC, Service, or any other init.
- The main container mounts remain unchanged — only the init containers
prepare volume contents.
## Test Plan
### Automated
```
$ terraform fmt -check -recursive stacks/claude-agent-service/
(no output — clean)
$ terraform -chdir=stacks/claude-agent-service/ init -backend=false
Terraform has been successfully initialized!
$ terraform -chdir=stacks/claude-agent-service/ validate
Warning: Deprecated Resource (pre-existing; use kubernetes_namespace_v1)
Success! The configuration is valid, but there were some validation warnings
as shown above.
```
### Manual Verification (after image bump + apply)
1. Bump `local.image_tag` in main.tf to the SHA of a build that has
`/usr/share/agent-seed/*` (verify with `docker inspect $IMAGE | jq ...`
or `kubectl run tmp --image ... -- ls /usr/share/agent-seed`).
2. `scripts/tg apply stacks/claude-agent-service`
3. `kubectl -n claude-agent get pods -w` — all init containers complete.
4. `kubectl -n claude-agent exec deploy/claude-agent-service -c claude-agent-service -- ls -la /workspace/.beads/metadata.json /home/agent/.claude/agents/beads-task-runner.md /workspace/scratch`
Expected: all three paths exist; first two are regular files with the
expected content, `scratch` is a directory.
5. `kubectl -n claude-agent exec deploy/claude-agent-service -c claude-agent-service -- jq -r .dolt_server_host /workspace/.beads/metadata.json`
Expected: `dolt.beads-server.svc.cluster.local`.
