feat(P02): Service block + Traefik emitter + atomic reload (REQ-077, gate C-10)
P02 — Traefik dynamic config generation + atomic reload protocol.
Parser (internal/jobspec/markdown.go):
- Extended WorkloadSpec with Health, Constraints, Affinity, Lifecycle
fields. Parsed restart/update/service/health/lifecycle/affinity/
constraints blocks. HealthBlock, AffinityRule, LifecycleBlock types.
Schema (internal/spec/schema/schema.go):
- ServiceValidator: restart.mode enum (service/on-failure/never),
update.strategy enum (rolling/canary/blue-green), health required,
service.bind IP validation (R-007 loopback opt-in). 98.5% coverage.
Traefik emitter (internal/emitter/traefik.go, REQ-077):
- TraefikEmitter renders /etc/traefik/dynamic/orca-<name>.yaml with
http.routers, http.services (servers = R-007 socket paths), TLS
(certResolver=orca, trust domain), healthCheck. RenderDrain sets
weight:0 per backend. RegisterTraefik wires process/podman/wasm.
Atomic reload (internal/emitter/traefik_atomic.go, gate C-10):
- WriteTraefikDynamic: write to path.tmp via WriteFileIdempotent, then
mv -f path.tmp path (atomic POSIX rename, Traefik fsnotify observes
IN_MOVED_TO). Traefik holds-last-good on malformed config. C-10 PASS.
22 packages pass, 20 bats pass, gofmt clean, verify-reqs 90 consistent.
Coverage: emitter 96.5%, jobspec 88.8%, schema 98.5%, sshpush 93.0%.
