Compliance & Audit
The evidence your compliance team actually needs
Most GPU power tools produce mutable, incomplete logs — if they log at all. Regulators, auditors, and incident responders increasingly require evidence that power actions were authorized, safe, correctly applied, and consistently governed.
Spark-XC makes every governed power action a Power Event Record on an append-only, tamper-evident evidence chain. Each record is independently replayable, and any modification to any historical entry breaks the chain — making tampering immediately detectable.
The hash-chain guarantee
Each Power Event Record includes a SHA-256 hash computed over the entry content and the previous entry's hash (deployments can additionally configure HMAC signing with an operator key). A single deletion, insertion, or modification anywhere in the chain produces a detectable break.
Power Event Record Chain
// Entry N-1
{ seq: 14819, hmac: "2e57...419f" }
// Entry N (current)
{ seq: 14820,
action: "SET_POWER_LIMIT",
enforced_w: 300,
readback_w: 300,
prev_hash: "2e57...419f",
entry_hmac: "f33c...8b02" }
// Chain valid — tamper-evident
If any entry is modified:
prev_hash in Entry N+1 no longer matches Entry N's hmac → chain break detected immediately
Compliance Use Cases
What auditors and regulators can now verify
Power Actions Were Authorized and Applied
Auditors can verify that each power action was authorized before it reached hardware and that the intended limit was actually applied — not just that a policy was written, but that the action was validated against live telemetry and confirmed by post-action readback.
Validated by
The GPU telemetry path checks each action against live hardware state and confirms the readback value after it lands. Every confirmation is captured in the action's Power Event Record — a continuous chain of evidence that governance was active.
Power Policies Were Consistently Governed
Every power request that passed or failed the policy and approval gate is on the chain — including which rule was evaluated, what authority was confirmed, and what parameters were submitted. Governance is not just claimed, it's proven.
Validated by
The policy and approval path records every gate evaluation as a structured Power Event Record. Denied requests, authorized requests, and rule matches are all preserved — an unambiguous governance record for any time period.
Incidents Have a Complete Timeline
When a power spike, telemetry mismatch, facility delta, or policy rejection occurs, regulators and incident responders need a complete, accurate timeline. Spark-XC records every validation path's outcome for every action — including the actions that were denied or flagged.
Validated by
The evidence chain links every Power Event Record across GPU, workload, facility, and policy, with millisecond timestamps. Replaying the chain gives investigators the exact sequence of events and the validation state at each point.
The Evidence Itself Has Not Been Tampered With
Traditional audit logs can be deleted, edited, or backdated. The hash chain makes any modification to a Power Event Record immediately detectable — auditors can verify chain integrity programmatically, independent of the system that produced it, before relying on any record.
Validated by
The tamper-evident evidence chain links every record to its predecessor via SHA-256 (HMAC signing available with an operator key). Integrity can be verified at any time by recomputing the chain. A valid chain shows that no record has been modified, inserted, or removed.
Framework Mapping
SPARK-XC maps to real compliance frameworks
