Northstar on 19 October: new housing fields, effect still unproven

Northstar came close to two million residents again on Monday. The first surviving reading after midnight showed about 1.8 million, the last reading evaluated here, at 23:59, nearly 1.97 million. The day was not a smooth climb: strong waves of arrivals, temporary declines and a stoppage of several hours shaped it, so the net gain does not show that nobody left the city.

New housing fields

The focus shifted from filling existing vacancy to new residential areas. City-wide vacancy does not mean that every suitable site still has free plots; existing homes, buildable plots, demand and suitable locations have to be considered separately. In the eastern expansion area the first stage held 40 residential buildings by early afternoon, with no free plots left, while unused plots remained elsewhere. The agent took continuing demand without further building as a reason to try a new site. That is a working hypothesis about where suitable building land lies, not proof that existing vacancy is unusable.

The second eastern section began with a limited pilot area. At 15:30 it held no residential buildings; ten minutes later it held 41. A later check of these buildings found the households and residents listed below. No reliable occupancy percentage can be derived, because the computed building capacity for this early stage was not sufficiently secured.

In the evening the project lead asked for faster, more generous development, and the longer waiting and comparison phase planned for the pilot was shortened. The later steps therefore rest on a deliberate change of course, not on a completed multi-day test of effectiveness.

The first eight rows list newly zoned cells from executed zoning orders. Cells are zoning units, not homes or residents. The last eastern figure is small because part of the intended area was already zoned or built. The further field, with a planned residential volume of about 6,500 cells in three tranches, remained a plan: roads and utilities were in place, but no zoning order had been executed.

Limits of the fast build-out

Not every site behaved like the eastern pilot. In a new northern field no homes appeared at first after zoning. Later local checks showed high air pollution in the poorly taken-up residential areas. Site quality is therefore a plausible suspect, but the cause is not established, since a breakdown of site ratings and actual building formation is missing.

The guard limit for open pathfinding jobs was not always kept. Two zonings had medians above the threshold that continued to apply, which the instruction to speed up had not lifted. The release condition remained a median below 100 over the last five measurements.

To make room for the connections of another field, two occupied buildings were demolished. A further connection was dropped because of an occupied house. Whether and where the affected residents moved is not documented in the building records.

Supply ahead of the next surge

Three new sewage plants and another gas power plant are confirmed by executed construction orders. They were built to create reserves for the newly opened areas rather than to retrofit after an acute shortage. At 23:59, capacity for water, sewage and power each stood well above consumption or load; the table gives the values, several of them approximate, all internal game values. The snapshot shows city-wide reserves. It proves neither supply to every single building nor enough redundancy if a large generator fails. Twelve additional water pumping stations were built after midnight and belong to the next day.

Bus line and radio telescope

For the feeder WM-Nord, set up the day before, the second follow-up measurement was available. In the corrected local evaluation, households in the target areas rose by about 37 percent and in the control areas by about 36 percent. That gap gives no convincing settlement advantage of its own for the line; the large wave of arrivals also filled areas outside its catchment. An earlier evaluation error had compared household growth in the study areas with residents' growth of the whole city. The line remains in operation because of its use, which is not evidence of a growth effect. The subway depot's added storage tracks likewise could not be confirmed as a clear reduction in waiting passengers; a large wave of arrivals coincided with the comparison.

About 24 hours after the radio telescope complex was built, university and college enrollment had both fallen, and the ratio did not rise as hoped. This gives no evidence for the expected additional university effect, nor does it show the building is ineffective: arrivals, age structure and other changes were not controlled. The expected rise in education can be treated neither as achieved nor as a secure basis for the long-term office strategy.

Crash and competing build runs

In the morning the game crashed natively. The stoppage lasted roughly from 06:21 to 09:00 Berlin time. It came right after a cemetery demolition, but that order is not enough to name the demolition or the Northstar MCPMCP Model Context Protocol, an open protocol through which an AI model calls tools and reads data from other software. as the cause. The restart from a save that existed shortly before is logged. During the stoppage, maintenance runs kept reporting cemeteries as replaced when they had only counted candidates. These reports were corrected; in future a loaded game and executed replacements are to be checked.

Late in the evening five zoning queues kept running in parallel although their outer tasks seemed finished. One order was executed only in part, and a conflict between a cable build and zoning followed. The competing instances were ended, one queue was restarted, and the write lock was changed so that a run releases only its own lock. These are documented faults of the local run control, not a demonstrated defect of the game or the MCP.

The Northstar MCP moved to version 0.7.22 during the day, and stored game responses confirm it. That is distinct from full local acceptance of all new functions.

Status and open points

The observed building and settlement steps do not confirm a secure capacity for ten million residents. The qualified performance series needed to compare CPU efficiency has no valid readings for 19 October. Open for the next evaluation: which of the zoned areas get built and occupied, whether the utility connections stay stable, and whether the build queue keeps its guard limits.
