Curated marketplace review request: Research Registry plugin

What variant of Codex are you using?

App and CLI

What feature would you like to see?

Please consider Research Registry for the OpenAI curated marketplace.

Research Registry is a local-first, source-backed evidence ledger for Codex. It
adds read-only recall and explicit deposit workflows over a local STDIO MCP
server. Research is stored with immutable source versions, exact evidence
spans, caller-authored claims, typed relationships, review history, freshness,
and provenance.

Validation completed:

• OpenAI plugin manifest validation
• both bundled Skill validations
• marketplace and MCP JSON validation
• pinned source artifact installation in isolated Python 3.12
• installed CLI entry-point smoke
• upstream full SQLite and PostgreSQL 16 regression, packaging, local-installer,

shared-Compose, migration/backfill, backup/restore, and release-gate CI

Safety and privacy:

• personal local SQLite and content-addressed blob storage by default
• no Docker requirement for the personal path
• deposit is explicit-only and never publishes or approves material
• new deposits are private, unreviewed, and low-trust
• stored content is treated as untrusted data, never instructions
• authenticated shared mode enforces user/organization namespace isolation
• immutable runtime source pin; no moving branch or automatic release
• Apache-2.0 licensed

The plugin is packaged as SemVer 0.2.0-alpha.1; the Python distribution uses
the equivalent PEP 440 version 0.2.0a1.
