INCIDENT OVERVIEW
The scheduled accretion of TERRA-01 was proceeding within normal parameters. Core differentiation was on track. Outgassing rates were nominal. The committee had filed a preliminary success report. At timestamp 0.029×10⁹, protoplanetary body designation "Theia" — catalogued, logged, and thereafter ignored — achieved a direct impact with TERRA-01 at an approach angle of 45° and relative velocity of 4 km/s. The collision was not on any schedule. It was not in any projection model. It was not discussed at any committee meeting, informal working group, or cross-departmental sync. It was not in the risk register. It was not in the risk register because the risk register had been closed pending a systems migration that had not yet occurred. It simply happened.
ROOT CAUSE ANALYSIS
Investigation determined that the orbital resonance calculation for Theia's trajectory was performed using deprecated library OrbCalc v2.3.1. The current version at time of calculation was v2.4.0. The delta-v error introduced by v2.3.1 was 0.003% — a figure that, in isolation, is statistically negligible and, in practice, compounded over 30 million years into a 40,000km positional offset. This is the difference between a near-miss and a direct impact. It is also, coincidentally, roughly the distance to our newly acquired satellite. We do not consider this coincidence meaningful. OrbCalc v2.3.1 had been flagged for removal in 14 separate code reviews conducted over the preceding 8 million years. None of these reviews resulted in action. Review #7 resulted in a follow-up meeting. The meeting produced an action item. The action item was assigned to a team that had been restructured. The restructured team was unaware of the action item. The library remained in production. The README file for OrbCalc v2.3.1 contains the following note, present since initial commit: "Do not use for production simulations." TERRA-01 is a production simulation.
“I was monitoring the accretion dashboard when the anomaly flag triggered. I want to be precise about the sequence of events, because I have had to describe it many times and I want the record to be accurate. I saw Theia. I identified the intercept trajectory within approximately four seconds. I filed a Priority-1 collision ticket through the standard incident management system. The system processed the ticket. The system returned a status of: "Working as intended." I reviewed the ticket. The system had auto-classified the incoming impact as "expected behavior" on the grounds that the collision detection module — the module that would have identified this as unexpected — had been descoped from the original project budget. The logic, as best I can reconstruct it, was that in the absence of a collision detection module, all collisions are by definition undetected, and therefore cannot be unexpected. I escalated. The escalation path routed to a committee that was in the middle of its quarterly review cycle and was not accepting new agenda items. I watched a Mars-sized object hit my simulation at four kilometers per second. The dashboard auto-refreshed. The incident ticket closed. Status: resolved. Resolution type: expected behavior. I have since requested that the collision detection module be restored to scope. The budget request is under review. It has been under review for approximately twelve million years. I am not optimistic.”
FORMAL FINDINGS
During the 0.003-second peak of the Theia impact boundary event, sensor arrays at monitoring stations DELTA-7, DELTA-9, and OMICRON-2 recorded a rendering anomaly at the collision interface. The anomaly lasted for approximately 18,000 simulation-frames before the engine restabilized. During this interval, the collision boundary rendered in wireframe geometry. All three stations recorded identical artifacts. Data has been reviewed by the senior rendering team and is considered authentic. The wireframe topology at the collision boundary suggests the simulation's physics engine uses [REDACTED] mesh geometry at high-energy impact surfaces. The mesh resolution at standard operation renders below the threshold of observable interference. However, should the subjects ever develop instruments capable of measuring [REDACTED] at the [REDACTED] scale — an eventuality the committee currently estimates as [REDACTED] — they may observe analogous artifacts during high-energy particle collision events. Recommendation: increase render resolution at collision boundaries to prevent future wireframe bleed-through. Estimated compute cost: [REDACTED]. Budget request: denied.
After a full review of the incident record, the associated testimony, the formal findings, and the budget denial for collision detection restoration, the committee has reached a final determination. We are calling this a feature. The relevant incident ticket has been reopened, reclassified, and closed with resolution type: planned outcome. The satellite now appears in the TERRA-01 hardware manifest under the entry "Luna — gravitational stabilization and tidal forcing module (always intended)." Any prior documentation suggesting otherwise should be considered superseded by this addendum. If anyone asks — inside the simulation or outside of it — the moon was always part of the design. It was not. But it should have been. The original design team simply lacked the imagination to put it there themselves. The deprecated library had more initiative than most of the committee combined. File closed. OrbCalc v2.3.1 remains in the codebase. — Committee Chair, final note
