- Add FleetWeightRegistry + resolveWeights() for per-product/per-request weight tunability with defaults fallback (backward compatible) - Add selectPreemptionVictim() pure function: only critical jobs may trigger, never evicts equal/higher priority, picks lowest-priority victim - Wire preemption into coordinator behind FLEET_PREEMPTION flag (default OFF) - Seat-limit enforcement: at seatLimit factories skip normal selection and attempt preemption of lower-priority running jobs for critical newcomers - Eviction preserves checkpoint, bumps leaseEpoch (fences zombie), requeues - 18 new tests (pure scheduler + coordinator integration) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Slice 1 — Tunable scoring weights + preemption
|
|
|
|
**Key files:**
|
|
|
|
- `services/platform-service/src/modules/fleet/scheduler.ts` — added `resolveWeights()`, `selectPreemptionVictim()`, `FleetWeightRegistry`, `RunningJobView`
|
|
- `services/platform-service/src/modules/fleet/coordinator.ts` — added `isPreemptionEnabled()`, `setWeightRegistry()`, seat-limit enforcement, preemption wiring
|
|
|
|
**Flags:** `FLEET_PREEMPTION` (default OFF = byte-for-byte Phase 2 behavior)
|
|
|
|
**Tests added:** 18 (14 scheduler pure + 4 coordinator integration)
|
|
|
|
- Weight resolution: defaults, partial override, per-request precedence, backward compat
|
|
- Preemption pure: critical evicts lower, never evicts equal/higher, picks lowest victim, capability checks
|
|
- Preemption integration: flag OFF no eviction, flag ON eviction + checkpoint preserved + zombie fenced + event
|
|
|
|
**Verify gate:** `pnpm --filter @lysnrai/platform-service exec vitest run src/modules/fleet` → 119/119 ✅; `pnpm build && pnpm test` → all green
|
|
|
|
## Follow-ups
|
|
|
|
- Weight registry could be loaded from Cosmos (per-product config doc) in a later phase
|
|
- Seat limit enforcement is tied to FLEET_PREEMPTION flag; could be decoupled later
