# Parameter Registry — Canonical Names, Defaults, and Floors

**Status:** v0.1 · Normative · Single source of truth for parameter names

This registry consolidates every kernel parameterization point into one table. It is normative for three artifacts, which MUST agree with it exactly:

- `spec/module.schema.json` (machine validation)
- `examples/family.config.json` and `examples/dao.config.json` (worked configs)
- the per-article "Parameterization" sections of the kernel annotations

**Rules of the registry:**

1. Parameter paths are dot-notation under the `parameters` object of a module config.
2. **Kernel default** applies when a module omits the parameter (Art VII: omission means inherit).
3. **Floor/Ceiling** values are kernel-enforced bounds. The JSON Schema encodes every bound marked *(enforced)*; bounds marked *(textual)* are stated in kernel text and checked by the test suite (Milestone 2) because JSON Schema cannot express them (cross-field relations).
4. Adding, renaming, or re-bounding a parameter is a **kernel-minor** change; removing one or tightening a floor is **kernel-major** (Art III).

## Textual constraints not expressible in the schema

These are kernel-text constraints validated by the Milestone 2 test harness, listed here so no one mistakes schema validity for kernel validity:

1. `quorum.escalated ≥ quorum.base`.
2. `amendment.thresholds.minor ≥ amendment.thresholds.patch` and `major ≥ minor`.
3. If `voting.secretBallot` is `true`, aggregate tallies and turnout MUST still publish to the ledger (Art X); only individual ballots may be sealed.
4. If `disputes.forum` is `"jury"`, `jurySize`, `selectionMethod`, and `termDays` MUST be set.
5. `emergency.suspendableScopes` may never include anything affecting Art II, III, V, or VI — the enum is the enforcement, but module authors composing custom scopes in userland inherit this prohibition.
6. A module's `userland.rules` may add obligations but may not subtract from any Art V invariant (Art VII supremacy ordering).
