[SLO definitions](/trust/slos)[Live status](https://status.mnemom.ai)

Measurement window opens at GA — no measured data published yet.

aegis-propagation

## Managed Rule propagation

Target

P95 ≤ 30 seconds from signed promotion to gateway-loaded

Source

[trust.mnemom.ai/slos/source#aegis-propagation](https://trust.mnemom.ai/slos/source#aegis-propagation)

Measurement query

`histogram_quantile(0.95, sum by (le) (rate(aegis_rule_propagation_seconds_bucket[5m])))`

No measured data yet. The first day publishes once the measurement window opens at GA — we do not pre-announce numbers we cannot defend.

aegis-freshness

## Rule-set freshness

Target

P99 ≤ 5 minutes under normal operation

Source

[trust.mnemom.ai/slos/source#aegis-freshness](https://trust.mnemom.ai/slos/source#aegis-freshness)

Measurement query

`histogram_quantile(0.99, sum by (le) (rate(aegis_ruleset_staleness_seconds_bucket[5m])))`

No measured data yet. The first day publishes once the measurement window opens at GA — we do not pre-announce numbers we cannot defend.

aegis-staleness-alert

## Staleness alert

Target

P0 on-call page at 24 hours stale

Source

[trust.mnemom.ai/slos/source#aegis-staleness-alert](https://trust.mnemom.ai/slos/source#aegis-staleness-alert)

Measurement query

`max(aegis_gateway_staleness_seconds) > bool 86400`

No measured data yet. The first day publishes once the measurement window opens at GA — we do not pre-announce numbers we cannot defend.

aegis-failover-availability

## Failover availability

Target

99.99% — gateway loads a verified rule set across multiple independent read tiers

Source

[trust.mnemom.ai/slos/source#aegis-failover-availability](https://trust.mnemom.ai/slos/source#aegis-failover-availability)

Measurement query

`sum(rate(aegis_ruleset_load_success_total[30d])) / sum(rate(aegis_ruleset_load_total[30d]))`

No measured data yet. The first day publishes once the measurement window opens at GA — we do not pre-announce numbers we cannot defend.

aegis-signature-verification

## Signature verification rate

Target

≥ 99.99%. Signature failure triggers P0 and fallback to an independent signing chain.

Source

[trust.mnemom.ai/slos/source#aegis-signature-verification](https://trust.mnemom.ai/slos/source#aegis-signature-verification)

Measurement query

`sum(rate(aegis_signature_verify_success_total[5m])) / sum(rate(aegis_signature_verify_total[5m]))`

No measured data yet. The first day publishes once the measurement window opens at GA — we do not pre-announce numbers we cannot defend.

aegis-recipe-fp-rate

## Recipe false-positive rate

Target

Per-recipe FP ratio over rolling 7-day window. Auto-rollback at per-tier threshold.

Source

[trust.mnemom.ai/slos/source#aegis-recipe-fp-rate](https://trust.mnemom.ai/slos/source#aegis-recipe-fp-rate)

Measurement query

`sum by (recipe) (rate(aegis_recipe_false_positive_total[7d])) / sum by (recipe) (rate(aegis_recipe_hit_total[7d]))`

No measured data yet. The first day publishes once the measurement window opens at GA — we do not pre-announce numbers we cannot defend.

aegis-mutation-phase-gate

## Mutation-phase gate compliance

Target

Per-bucket arena detection rate, sustained entry/exit thresholds with hysteresis

Source

[trust.mnemom.ai/slos/source#aegis-mutation-phase-gate](https://trust.mnemom.ai/slos/source#aegis-mutation-phase-gate)

Measurement query

`aegis_mutation_phase_gate_state{bucket=~".+"}`

No measured data yet. The first day publishes once the measurement window opens at GA — we do not pre-announce numbers we cannot defend.
