The accumulated repair, replacement, calibration, and staffing burden left behind after a capability regime expands faster than the system's long-run ability to maintain it.
Maintenance overhang appears when a regime expands faster than it can keep its old and new surfaces repaired together.

Maintenance overhang is the trailing burden created when a capability regime adds more infrastructure, specialist surfaces, and operating dependency than it can comfortably keep repaired over time.
It is an overhang because the burden remains after the expansion decision has already been made. New lines, wards, depots, relay towers, operator schools, and spare-parts chains keep demanding labor and material every cycle, even when the original surge of growth or conquest has passed.
Many worlds are good at describing what a new capability unlocks and weak at describing what it leaves behind. Maintenance overhang is the concept that captures that long-tail drag.
This matters because a regime can stay impressive in peak moments while already becoming weaker in ordinary time. Repair queues lengthen, specialists thin out, calibration slips, peripheral nodes get serviced later, and the system starts narrowing its practical scale without announcing a formal collapse.
Ask four questions when testing maintenance overhang.

What new lines, nodes, or institutions now require routine upkeep?
A maintenance overhang is not just ordinary upkeep or one bad repair season. It matters when the long-tail burden of keeping the system alive starts outrunning the labor, parts, training, and attention needed to reproduce the regime cleanly.
If a capability still exists on the map but increasingly works through backlog, patchwork, expert scarcity, or selective abandonment, the regime is carrying maintenance overhang.
The clearest signs are deferred repairs, cannibalized parts, uneven service quality, specialist shortages, and a practical narrowing of the system before any formal shutdown is announced.
A rail or ward network may still cover the same territory on paper, yet be carrying maintenance overhang if peripheral branches now survive only through patchwork repair and selective abandonment.
That is what makes overhang easy to miss at first. The map still shows scope, but the regime is already narrowing in practical reliability and service quality.

Many glossary abstractions become richer when viewed inside the spatial module.
Use this appendix when you want to continue by program branch or operating scale after the page has been read.
Program Branch
Capability Regimes
Explain how technology, magic, infrastructure, communication, and transformation capacity rewrite baseline constraints.
Start with the operating regime, price the capability through diffusion or monopoly models, compare a regime-rewrite case, then run a capability sanity check.
Explain transition, disturbance, collapse, recovery, and reassembly across eras and stress cycles.
Start with transformation and failure models, trace residue and recovery paths, compare a collapse or successor-order study, then run a failure-mode review.
Glossary entries define Spcent's shared vocabulary. They are conceptual anchors designed to stabilize how an abstraction is used across pages and modules.
