Access Control, Upgrades and Governance

Introduction

This branch maps who can change protocol code, parameters, funds, or availability; how quickly; through which keys and contracts; and with what monitoring, escape, and recovery constraints.

Why It Matters

An “admin” is a bundle of protocol powers and operational risks. Upgradeability can patch defects but also introduces initialization, storage, authorization, capture, and permanent-control failure modes.

Mental Model

Draw an authority graph from human/key origin through multisig, governor, timelock, proxy admin, implementation, guardian, and pause mechanism to each protected transition. Treat delay and observability as security properties.

Questions This Branch Answers

• Which actor can perform each privileged transition, and when?
• What does an upgrade preserve, invalidate, or silently reinterpret?
• How are emergency powers bounded and eventually removed or reviewed?

Scope

Ownership/roles, separation of duties, multisigs, timelocks, guardians, governance lifecycle, bounded parameters, capture, proxy storage, initializers, UUPS/transparent/beacon patterns, and immutability tradeoffs.

Out of Scope

Governance-token valuation, legal entity design, universal voting recommendations, social-layer guarantees, and production multisig key ceremonies.

Dependencies

contract architecture, delegate calls and storage, and signature authority.

Candidate Note Roadmap

• roles-ownership-and-separation-of-duties — Turn vague admin power into named, minimal capabilities.
• multisig-and-admin-key-risk — Model signer thresholds, compromise, loss, and execution ownership.
• timelocks-and-emergency-guardians — Combine delayed change with bounded incident controls.
• governance-lifecycle — Trace proposal, voting, queuing, execution, cancellation, and expiry.
• parameter-bounds-and-governance-capture — Enforce safe ranges and examine concentrated influence.
• proxy-storage-and-initializers — Inspect slots, initialization state, and implementation binding.
• uups-transparent-and-beacon — Compare upgrade authority and call-routing patterns.
• immutable-vs-upgradeable-deployments — Choose patchability, escape hatches, or immutability explicitly.

Future Project

A Governed Treasury with separated roles, multisig-originated proposals, timelocked execution, parameter bounds, a narrow guardian, and a storage-compatible educational upgrade.

Initial Invariants

Unauthorized proposals never execute; execution respects minimum delay; guardian actions remain within emergency scope; upgrades preserve declared storage/accounting properties; initialized components cannot be taken over again.

Initial Threat Model

Key compromise or loss, governance capture, quorum/flash-vote manipulation, malicious proposal payloads, initializer takeover, selector/storage collisions, upgrade rollback failure, and permanent or abusive pause.
