Acceleration Module - Future Enhancements

Scope

Forward-looking enhancements for backend reliability, capability negotiation, plugin/security hardening, and multi-device acceleration behavior.

Design Constraints

• Preserve stable backend contracts for existing acceleration consumers.
• Keep backend selection deterministic under equivalent capabilities and requirements.
• Ensure plugin/security integrity checks execute before dynamic backend execution.
• Keep optional backend features degradable with explicit fallback signaling.

Required Interfaces

Interface	Consumer	Notes
backend registry and selection APIs	compute-intensive runtime consumers	stable capability and selection semantics
backend dispatch interfaces	index/geo/graph/llm paths	explicit success/failure/fallback contracts
plugin and integrity interfaces	dynamic backend loading paths	trust and validation controls
multi-device interfaces	distributed acceleration paths	bounded fan-out/merge behavior
resource manager interfaces	shared GPU/acceleration consumers	deterministic lease and limit behavior

Implementation Notes

Registry and Dispatch Hardening

Priority: High Target: Q3-Q4 2026

• harden capability selection and fallback determinism under mixed backend availability
• standardize degraded-state handling and diagnostics in dispatch paths
• improve contract-level validation for backend capability mismatches

Plugin and Integrity Hardening

Priority: High Target: Q4 2026

• strengthen plugin validation and integrity evidence paths
• improve deny/failure diagnostics for trust-check failures
• align plugin/security behavior with explicit fail-closed runtime semantics

Multi-Device and Resource Hardening

Priority: Medium Target: Q4 2026

• improve multi-device merge and fan-out resilience under partial failures
• strengthen resource lease and bounded-memory behavior under contention
• expand operational diagnostics for capacity and device-health conditions

Performance and Capacity Hardening

Priority: Medium Target: Q1 2027

• re-baseline dispatch and backend performance envelopes by release profile
• keep fallback overhead and queue growth bounded under sustained load
• lock benchmark-backed release thresholds for critical acceleration paths

Test Strategy

• focused regression suites for capability matrix and fallback behavior
• plugin/security trust-check regression matrix
• multi-device and resource-contention failure-injection tests
• benchmark regression gates for dispatch/backends/fallback overhead

Performance Targets

• stable p95 and p99 envelopes for representative acceleration workloads
• bounded throughput regressions against release baselines
• bounded memory and queue growth under sustained multi-device load

Security / Reliability

• fail closed on invalid capability/integrity/runtime states
• preserve deterministic fallback and dispatch behavior
• prevent unbounded growth in resource manager and dispatch queues

Risk Backlog

Risk 1: backend selection drift under mixed capability environments

Severity: High Signal: inconsistent backend choice for equivalent requirements. Mitigation: deterministic selection checks and regression packs.

Risk 2: plugin trust path degradation

Severity: Medium Signal: increased validation failures or ambiguous deny diagnostics. Mitigation: stronger trust-path instrumentation and coverage.

Risk 3: multi-device resource pressure under sustained load

Severity: Medium Signal: queue buildup, merge delay, or lease contention spikes. Mitigation: bounded resource controls and endurance regressions.
