Primes¶
- Adaptation
- These constraints are not incidental; they define the adaptive capacity of the system. Environmental change. The environment, conditions, or problem the system faces has shifted in a way that reduces the fit of the prior configuration.
This sourceFoundational treatment of homeostasis: physiological variables are maintained within finite ranges by coordinated self-regulatory feedback that damps disturbance without reorganizing the system — the standing restoring apparatus distinguished here from adaptive structural change.

- Balance
- … balance, each achieving compositional coherence through different distribution strategies. Ecology and systems biology: Balance to population dynamics, predator-prey relations, and nutrient cycles; homeostatic equilibrium in living systems as the dynamic balancing of competing physiological demands.
This sourceIntroduces homeostasis: physiological variables (temperature, blood pH, glucose) are held within bounded ranges by continuous regulatory feedback — the canonical dynamic equilibrium maintained by ongoing adjustment.

- Boundedness
- Boundedness is not the same as a safety property in general — Cannon's (1932) framing of homeostasis as one regulatory mechanism among many illustrates how bounded magnitudes sit within a broader family of "stay within limits" safety properties.
This sourcehomeostasis maintains physiological variables (temperature, glucose, pH) within finite ranges via regulatory feedback — boundedness as one 'stay-within-limits' safety mechanism among many.

- Buffering
- Biology & Physiology: Blood glucose buffering via liver glycogen and hormonal feedback (insulin/glucagon) absorbs meal-to-meal variation and fasting periods, an instance of the homeostatic regulation Cannon (1932) described as the body's maintenance of internal constancy through reservoir-and-feedback mechanisms.
This sourceFoundational treatment of homeostasis: physiological variables (blood glucose, pH, temperature) are held within narrow ranges by reservoir-and-feedback regulation, the biological instance of buffering meal-to-meal and fasting variation.

- Discrepancy-Driven Correction
- In homeostatic biological regulation the setpoint (body temperature, blood glucose, blood pressure) is compared to the measured state, and the gap drives endocrine, neural, or behavioural correction on a timescale set by the slowest mechanism in the chain.
This sourceIntroduces homeostasis: regulated biological variables held near setpoints by negative-feedback correction.

- Homeostasis
- software and infrastructure (Russell's (2019) Human Compatible analysis of homeostatic agents bears on autoscaling systems maintaining latency or load targets; rate-limiting; load-balancers; self-healing clusters) — all deploy the sensor-comparator-actuator closed-loop structure.

- Reserve
- The pattern recurs unchanged across engineering safety factors (Petroski, 1985), inventory buffers, capital reserves, cardiac reserve and other physiological capacities (Cannon, 1932), seed banks, spinning reserve on power grids, and memory headroom in computing systems, which together establish reserve as one of the most substrate-neutral structural primes in the catalog.

- Stability
- Macroeconomics: a central bank targets a stable inflation regime, the question being whether the policy rule makes the operating point dynamically stable against shocks. Political regimes: a polity's tendency to return to a characteristic regime after shocks, the comparative-politics literature being structurally identical to dynamical-system stability analysis. Physiological homeostasis: pH, temperature, and glucose are operating points held by restoring dynamics (buffering, sweating, insulin) against perturbations.

- Systems Thinking
- Medicine & physiology: Chronic disease is increasingly framed as a dysregulated network—a homeostatic control system whose feedback loops have shifted to a new, pathological set-point—rather than a single broken part, an organizing idea traceable to Cannon's (1932) account of homeostasis as the body's self-regulating feedback machinery.
