A structural-dynamics engineer named Grace leaned closer to her camera.
"You're treating the harmonic as phase evidence rather than amplitude evidence."
"Yes."
"Because amplitude is below calibration confidence."
"Correct."
She looked offscreen, likely at her own data.
Isaac continued.
"The current Nexora proposal lowers actuation frequency during the transition. That reduces one source of excitation. It also degrades regulation authority. The system compensates later by consuming reserve during maneuver correction."
Adrian displayed the comparison table.
"Using the normalized mission budget," Isaac said, "the workaround adds roughly nine to eleven days of useful control before reserve constraints become the dominant failure mechanism."
One Nexora engineer shook his head.
"That assumes the controller responds exactly as modeled under low authority."
"You're right."
The man seemed surprised by the answer.
Isaac pointed at the lower range.
"That's why the error band is here. If the controller performs better, you might get twelve or thirteen days. If it performs worse, fewer. None of those outcomes make a twenty-five-day implementation schedule acceptable."
Grace spoke again.
"I ran his coupled model last night. The resonance condition reproduces the flight signature."
A second voice came from Colorado.
"Same here. We tested three parameter bands. The harmonic drops when we decouple the thermal stiffness shift from the actuator excitation."
Cameron's expression tightened.
"Those are desktop reproductions, not hardware validation."
"There is no spare flight-equivalent hardware configured for this exact degradation state," Eleanor said. "We all know that."
"Which is precisely why we should use the approved conservative workaround."
Isaac looked at the camera.
"A workaround isn't conservative if the clock kills you before the fix arrives."
The room went quiet.
Adrian brought up the third sheet.
Isaac's alternative did not attempt to suppress the valve entirely. It altered command timing within a narrow operational envelope so that the actuator input no longer reinforced the coupled resonance during the thermal transition. The approach preserved pressure authority while reducing the repetitive fatigue input.
He had derived seventeen parameters.
None represented a secret code or direct command sequence in the real-world sense. They were model terms for the fictional system, and each would still require independent translation, verification, and mission authorization before anything reached the vehicle.
"This is not ready to upload," Isaac said before anyone else could imply otherwise. "It's a framework. Every parameter needs independent review. The safe move is not to trust me. The safe move is to try as hard as you can to prove me wrong before the vehicle forces the decision."
That sentence changed the room more than any equation.
Grace smiled faintly.
"Finally, someone says it."
Cameron did not.
The review continued for three hours.
Engineers challenged assumptions. One questioned material-property extrapolation. Another objected to the fatigue model. A controls specialist showed a corner case where Isaac's first parameter set could induce an undesirable transient after a maneuver.
Isaac thanked him and changed the model.
He did not defend being wrong.
He defended the process that found it.
By the end of the session, the coupled-failure model had survived enough independent review that Eleanor authorized expedited validation of the remediation framework.
Cameron asked for a formal dissent to be attached.
"Of course," Eleanor said.
His video went dark four seconds later.
The connection remained active.
For twelve seconds, his microphone continued transmitting the scrape of a chair, a door closing, and a muffled sentence from someone offscreen.
"He told you this in seventeen."
Then the audio ended.
No one commented on it.
Eleanor concluded the call.
Adrian sat back from the monitor.
"Did everyone hear that?"
Isaac collected the handwritten pages.
