IIP-063: Replication durability and HA

IIP-063 Roadmap Record

IIP-063: Replication durability and HA is an IOI roadmap record for the Agentgres surface. Its status is Active implementation in Horizon 0 — contract convergence and it belongs to the State track. Implementation is underway and has current code anchors, but the stated scope is not complete. The canonical scope is: Durability classes up to quorum replication, combined-flush mux log, and writer-epoch HA without consensus; branch/staged-effect durable objects planned.

Surface Context

This record should be read as part of the Agentgres roadmap, not as a replacement for source papers or product pages. The parent surface gives the broader context for why this milestone exists, what it depends on, and which IOI surfaces it supports. The parent Agentgres surface has no surface-level dependency in the current roadmap model. The parent surface unblocks later roadmap surfaces: hypervisor, ioi, sas, aiagent, embodied.

Evidence And Verification

The record is designed to make roadmap evidence crawlable and separable from research claims. This item also names item-level dependencies: IIP-018. Evidence links below point to the paper, release, repository, developer documentation, or product page that supports this milestone.

• Agentgres crate

Canonical Relationship

This page is the canonical roadmap record for IIP-063, while the parent roadmap surface and linked research pages remain the canonical sources for broader product and protocol context. Internal links point here when the milestone status, horizon, dependencies, or evidence trail for Replication durability and HA matters.

Roadmap Role

IIP-063 exists to clarify roadmap status, bounded scope, horizon placement, and evidence relationships. Technical concepts flow through this page to canonical research pages, while product or runtime context flows to the relevant surface page. This preserves a complete status and evidence trail without making roadmap records compete with deeper IOI papers.
