C.26.3:4.8 - Homeostasis, allostasis, and architecture work
Homeostatic wording is useful when the claim concerns keeping a variable or bundle inside a stable range. Allostatic wording is useful when preserving the named function requires one or more separately governed setting, boundary, environment, access, staffing, routing, protocol, cache-policy, or operating-regime changes. The wording does not decide whether each item is a Method, description, plan, Work, transformation, relation, or resulting state.
Use the minimal reading that carries the case:
| Reading | Use when | Practical output |
|---|---|---|
| Scalar quality repair | One characteristic or Q-bundle dimension is enough. | Apply C.25, measurement patterns, or evidence patterns as appropriate. |
| Homeostatic envelope | The target is to keep a bundle inside a stable range under disturbance. | State variables, range, disturbance, sensor, candidate intervention with its recovered direct object, and failure mode. |
| Allostatic envelope | Function is preserved through one or more separately governed changes. | State the proposal’s exact Method or description, setting proposal, WorkPlan, access or permission claim, or Bridge proposal or description; separately state any dated Work, actual transformation or other change, obtaining relation occurrence, resulting state, and moved cost. |
| Probe-coupled viability | The measurement, dashboard, review, or readiness check changes the envelope it reports, but its output is used as a passive read for the decision. | Coordinate with C.26.1. |
| Enacted viability state | Coordinated work, behavior, or traces support a collective-state reading relevant to the envelope that no single report or export faithfully carries. | Coordinate with C.26.2. |
Do not call every adaptation allostasis. The term earns its place only when stability-through-change is the useful architecture reading.
