Bylines, paper authorship, correspondence addresses and the founder blurb under each post named an individual. They name the organisation that published the work instead: the brand on posts and pages, the research byline on papers, and research@ in place of a personal address. Both are what these repositories already used elsewhere — nothing new was coined. Co-authors are untouched. Where a paper named someone else alongside, they stay named; only the one byline changed. Bibliography entries, running heads, PDF metadata and affiliations move with it, so a citation still resolves to whoever the cited paper names. Sample and fixture data uses the placeholder name these tests already use elsewhere, so no assertion changed meaning. Co-authored-by: Hanzo Dev <[email protected]>

On-Chain DEX Governance
|
|
|
|
DAO governance for DEX parameters: fee tiers, pool weights,
|
|
listing/delisting, upgrade proposals.
|
|
|
|
Maps to:
|
|
- lux/exchange: governance contracts
|
|
- lux/node: on-chain parameter updates
|
|
|
|
Properties:
|
|
- Quorum: parameter changes require vote threshold
|
|
- Timelock: changes have mandatory delay
|
|
- Bounded: parameters stay within safe ranges
|
|
- Monotone: governance power ∝ stake
