v1.3.0

Economics Layer: Observability Metering, Delegation Tokens, and SLA Framework. Backward compatible with v1.2.1.

Added

Observability Metering (E1)

• Usage tracking: MeteringStorage protocol, InMemoryMeteringStorage, SQLiteMeteringStorage
• Usage API: GET /usage, /usage/aggregate, /usage/summary, /usage/agents, /usage/consumers, /usage/stats, /usage/export; POST /usage, /usage/batch, /usage/purge, /usage/validate
• Task metrics: Tokens, duration, API calls recorded per task via MeteringStore adapter
• Integration: Middleware records usage on task completion; create_app(metering_storage=...)

Delegation Tokens (E2)

• Delegation model: DelegationToken, DelegationConstraints (max_tasks, expires_at); JWT with EdDSA
• Delegation API: POST /asap/delegations (create token), DELETE /asap/delegations/{id} (revoke)
• Storage: DelegationStorage protocol, InMemoryDelegationStorage, SQLiteDelegationStorage; revocation with cascade
• CLI: asap delegation create, asap delegation revoke
• Validation: validate_delegation, scope checks, max_tasks enforcement, revocation lookup

SLA Framework (E3)

• SLA schema: SLADefinition in manifest (availability, max_latency_p95_ms, max_error_rate, support_hours)
• SLA metrics: SLAMetrics, SLABreach; SLAStorage protocol, InMemorySLAStorage, SQLiteSLAStorage
• Breach detection: BreachDetector, evaluate_breach_conditions; callback + WebSocket broadcast
• SLA API: GET /sla, /sla/history, /sla/breaches
• WebSocket: sla.subscribe / sla.unsubscribe for real-time breach notifications
• Showcase: asap.examples.v1_3_0_showcase — Delegation, Metering, SLA in one command

Changed

• README: v1.3.0 showcase command; Economics Layer marked complete in roadmap
• create_app: metering_storage, delegation_key_store, delegation_storage, sla_storage parameters

Technical Details

• Python: 3.13+
• Tests: 2200+ passing; cross-feature integration tests (SLA + Metering + Delegation + Health)
• Coverage: >95%
