Containment requires absorption.
Absorption requires slack.
Slack had been optimized away.
R₀ held above one.
Not accelerating.
Not declining.
Persistent reproduction.
That was the danger zone.
Jasmine analyzed damping capacity across layers.
Damping coefficient was flattening.
Amplification was no longer decaying naturally.
It was sustaining.
Keith noticed something subtle.
Market makers were quoting—
But only inside micro-windows.
Milliseconds of depth.
Then withdrawal.
Liquidity as flicker.
Maya modeled energy accumulation.
"Integrated amplification is rising," she said.
"Even without visible spikes."
Keith understood immediately.
"You're saying stress is storing."
"Yes."
"Like strain in a fault line."
The next fluctuation was statistical noise.
A data revision.
Marginal.
Ordinarily ignored.
It wasn't ignored.
In New York City, index futures reacted before the revision timestamp fully disseminated.
In London, rates desks widened pricing bands preemptively.
In Tokyo, safe-haven demand surged before equity confirmation.
Prediction replaced observation again.
Jasmine recalculated branching depth.
Cascade depth shrinking.
Shocks reaching system-wide relevance faster.
Even modest ones.
Keith's screen flickered.
Cross-asset correlation snapped briefly into alignment—
Then overshot.
Synchronization spike.
Then desynchronization.
Oscillation amplitude increasing.
Maya whispered:
"That's resonance."
She formalized it.
Driving frequency approaching natural frequency.
When external disturbances match internal timing—
Energy accumulates instead of dissipates.
In Chicago, futures volume surged without directional catalyst.
In Frankfurt, bund yields swung wider intra-minute than prior weekly averages.
In Singapore, volatility-targeting models forced synchronized deleveraging across unrelated strategies.
Containment layers were interacting.
Not buffering.
Jasmine's voice remained even.
"Gamma is no longer positive."
Keith looked at her.
"That means—"
"It means amplification is self-sustaining."
No crash.
No halt.
No headline.
Just widening swings.
Just faster propagation.
Just thinner absorption.
In Zurich, capital preservation mandates triggered incremental reductions.
In Hong Kong, liquidity providers shifted from risk warehousing to flow matching only.
In Washington, D.C., oversight remained observational—no statutory breach, no mandate to intervene.
Because nothing had technically failed.
Yet containment had.
Maya summarized quietly.
"R₀ above one."
"Gamma flat."
"Resonance building."
Keith nodded.
"And stored energy increasing."
The system wasn't breaking outward.
It was tightening inward.
Stress accumulating beneath visible volatility.
Containment requires slack.
Slack requires redundancy.
Redundancy had been eliminated for efficiency.
Efficiency is fragile near criticality.
The next fluctuation wouldn't need to be large.
It would only need—
To arrive at the right frequency.
