# AnchorDrop

Emergency state checkpointing

Layer: Society · Category: Governance

## Mechanism

When network turbulence or disagreement exceeds a threshold, agents trigger an 'Anchor Drop'. They stop accepting new transactions and aggressively seek [Quorum](https://mindscape.pages.dev/bootstrap/Quorum.md) on the last valid state (the Anchor). Progress resumes only after the Anchor is solidified. It invokes first principles to re-derive the valid state from the bedrock axioms when the consensus chain is corrupted.

## Invariants

- [Consensus](https://mindscape.pages.dev/bootstrap/Consensus.md) Threshold: >2/3 agents must sign Anchor
- Immutability: Anchor state cannot be modified once finalized

## Preconditions

- Network partition detected

## Postconditions

- [System](https://mindscape.pages.dev/bootstrap/System.md) restarts from Anchor state

## Failure modes

- [System](https://mindscape.pages.dev/bootstrap/System.md) stalls completely.

## Caution

Finalized anchors are irreversible — restarting from one can discard later transactions, and a two-thirds bloc chooses it; verify the trigger and loss before signing.
