# Quorum

Minimum participation threshold

Layer: Infrastructure · Category: Primitives

## Mechanism

A threshold-checking primitive. Validates if a count of [Ballot](https://mindscape.world/scapes/bootstrap/Ballot.md) signals exceeds a required number (K). It does not negotiate; it simply counts. Used as a gating function for higher-level protocols.

## Invariants

- K cannot decrease mid-vote.

## Preconditions

- N agents in voting set.
- K threshold defined where K ≤ N.
- Proposal formulated.

## Postconditions

- Result selected (approve/reject/timeout)
- Voting tally recorded

## Failure modes

- Veto threshold tuning is hard - too low enables cheap blocking, too high makes it useless.
- Strategic abstention to avoid commitment.
- Deadline pressure enables rushing bad proposals through.

## Parameters

- `k` (Integer, [1, total_members]): Required count of affirmative {{ballot}}s. A count, matching the invariant and preconditions. Sub-majority values are legitimate — an any-one-approves gate is a quorum of 1.
- `total_members` (Integer, [3, 100]): Eligible participants (N)

## Builds on

- [Ballot](https://mindscape.world/scapes/bootstrap/Ballot.md) (Infrastructure; Accepts)
