Reconstruct any decision in seconds.

Every decision produces a complete trace. Deterministic replay guaranteed - same inputs, same rule versions, identical output.

The Problem

"Why did that happen?" takes hours. Sometimes the answer is "we can't tell."

When the wrong action executes, the first question is always "why?" Today, answering that question means digging through logs, prompts, model outputs, and application code. It takes hours. Sometimes the answer is "we can't tell."

The Solution

Complete traces. Deterministic replay.

Every Memrail decision produces a complete trace: what rules were considered, which ones matched, which were suppressed (and why), what action was prescribed, and what the result was. This trace is deterministic - given the same inputs and rule versions, it produces the identical output.

Anatomy of a Trace

What a decision trace contains

Rules evaluated

All rules evaluated at this decision point, including which triggers matched the provided context.

Suppression reasons

Which rules were suppressed - by cooldowns, exclusion groups, lifecycle state, or ranking - and the specific reason for each.

Prescribed actions

The winning rules and their prescribed actions, including the score calculation for each candidate.

Full context snapshot

The policy version in effect, the full context (state, tags, recent events) that was provided, and the timestamp of the decision.

Who Benefits

What traces enable for each stakeholder

Stakeholder
What they get
Example
Engineering
Instant root cause analysis
"The SLA escalation rule didn't fire because the event was emitted 45 minutes ago, inside the 2-hour cooldown window."
Compliance
Reproducible audit evidence
"At timestamp T, given context C, with rule version V, the system prescribed action A. This is reproducible."
Operations
Suppression analytics
"In the last 24 hours, rule X was suppressed 47 times by cooldown, 12 times by exclusion group conflict."

Decision Traces in Action

From hours of forensics to seconds of clarity

Every decision trace provides a complete, deterministic record. Replay any decision with the same inputs and rule versions to get identical output. No guessing, no archaeology, no ambiguity.

Questions

Frequently asked

How long are traces retained?

Trace retention is configurable per customer. Once written, traces are immutable - they cannot be modified or deleted during the retention period. This is critical for audit and compliance use cases.

Can I replay a decision from a trace?

Yes. Because Memrail is deterministic, you can replay any decision by providing the same context, the same rule versions, and the same timestamp. The output will be identical. This is what makes traces audit-grade.

What is the performance impact of generating traces?

Trace generation is a side effect of evaluation, not an additional step. Every decision naturally produces a trace as part of the evaluation process. There is no separate tracing overhead - it is built into the decision path.
