feat(P05): CLI-side scheduler + CEL constraints + affinity (REQ-083)
P05 — Scheduler moves from daemon-side to CLI-side (R-001) with runtime-awareness.
Scheduler (internal/scheduler/scheduler.go, REQ-083):
- Pure Schedule(nodes, req) -> []Placement. Job=1 best-fit, Service=count
replicas (anti-affinity default, colocation permitted), DaemonSet=1 per
matching node. Score(node, req) = (FreeCPU*1000 + FreeMem); fits checks
runtime compat (wasm->wasmtime, pve-vm/ct->proxmox), constraints (CEL AND),
capacity. Affinity scoring (target + weight, anti-affinity for spreading).
CEL evaluator (internal/scheduler/cel.go):
- Hand-rolled recursive-descent (no CEL dep in go.mod). Subset: node.* attrs,
literals, ==/!=/>=/<=/></>, in/not in, and/or/not, parens. Anything outside
subset returns error (no silent wrong answer). Schedule treats eval errors
as non-fit (node skipped).
23 packages pass, 20 bats pass, gofmt clean, verify-reqs 90 consistent.
89.5% coverage on internal/scheduler.
