ci/woodpecker/manual/security-scan Pipeline failed
ci(security-scan): auto-fix agent that opens PRs for Trivy findings
The cron security-scan now ends in an autonomous fix loop:

  iac-scan       → trivy-iac.json
  image-scans    → trivy-image-N.json (per scanned image)
  security-fix-agent (master only):
    1. Gates on >=1 CRITICAL/HIGH finding across all JSON outputs.
    2. Creates branch security-fix/<date>-<short-sha>.
    3. Hands the workspace to Claude Code in headless --bare mode
       (subscription-backed via CLAUDE_CODE_OAUTH_TOKEN, no API key)
       with a narrow tool allowlist (Read/Edit/Write/Glob/Grep —
       no Bash). The agent reads the JSON, applies surgical fixes
       under ansible/, opentofu/, kubernetes/, ci/images/, and writes
       a Markdown summary to /tmp/security-fix-summary.md.
    4. If the agent produced a diff, the step commits as
       "Security Fix Agent <security-bot@renner.uno>" and pushes to
       Gitea, then opens a PR via the pulls API using a dedicated
       security_bot_token (NOT gitea_admin) so the PR is visibly
       machine-authored.

The step is gated to branch=master so it doesn't fire on its own
PR branches — those still trigger the scan workflow as a re-validation
gate, but skip the agent (no fork-bombing).

Trivy now writes JSON output (--format json -o), and findings appear
both in the JSON and as one-line summaries in the step log via jq.
The legacy --exit-code 1 was kept off so the workflow always reaches
the agent step on master; on PR branches the scans are informational
and a human reviews the agent's PR.

Required Woodpecker secrets (added by user, not by this commit):
  - claude_code_oauth_token (claude setup-token output)
  - security_bot_token      (Gitea PAT for the security-bot user)

Required Gitea setup (also out of band):
  - User "security-bot" with email security-bot@renner.uno
  - Write collaborator on gitea_admin/homelab

Agent constraints live in ci/agents/security-fix/prompt.md so they're
diffable + reviewable separately from the pipeline plumbing.
