## Context
The claude-agent-service K8s pod (deployed 2026-04-15) provides an HTTP API
for running Claude headless agents. Three workflows still SSH'd to the DevVM
(10.0.10.10) to invoke `claude -p`. This eliminates that dependency.
## This change
Pipeline migrations (SSH → HTTP POST to claude-agent-service):
- `.woodpecker/issue-automation.yml` — Vault auth fetches API token instead
of SSH key; curl POST /execute + poll /jobs/{id} replaces SSH invocation
- `scripts/postmortem-pipeline.sh` — same pattern; uses jq for safe JSON
construction of TODO payloads
- `.woodpecker/postmortem-todos.yml` — drop openssh-client from apk install
- `stacks/n8n/workflows/diun-upgrade.json` — SSH node replaced with HTTP
Request node; API token via $env.CLAUDE_AGENT_API_TOKEN (added to Vault
secret/n8n)
Documentation updates:
- `docs/architecture/incident-response.md` — Mermaid diagram: DevVM → K8s
- `docs/architecture/automated-upgrades.md` — pipeline diagram + n8n action
- `AGENTS.md` — pipeline description updated
## What is NOT in this change
- DevVM decommissioning (still hosts terminal/foolery services)
- Removal of SSH key secrets from Vault (kept for rollback)
- n8n workflow import (must be done manually in n8n UI)

Pipeline authenticates to Vault via K8s SA JWT, fetches devvm_ssh_key
from secret/ci/infra, SSHes to DevVM to run Claude Code headlessly.
