feat: mock atomizer and work-performer services with contract tests (phase 11)
- services/atomizer: standalone Go module implementing §5.1 — Anthropic
OpenAI-compatible chat completions by default, native /v1/messages when
LLM_API_STYLE=anthropic, strict-JSON prompting, defensive fence-stripping
parse with one retry, deterministic equal-split fallback without an API
key, exact coefficient-sum normalization, bearer auth
- services/work-performer: Node 20 http server implementing §5.2 — single
concurrency, /work/{jobId}/TASK.md preparation, attachment downloads,
optional shallow git clone, claude CLI execution with JSON output,
simulated success when the CLI is unavailable (offline demo), artifact
endpoint, idempotent HMAC-signed callbacks with retry, best-effort cancel
- compose profile 'mocks': separate builds/ports/tokens, healthchecks,
${HOME}/.claude(.json) mounted read-only into the performer
- contract tests (go test -tags=contract) for both services; Makefile
test-contract target; verified live incl. a real Claude Code job run
