+Plugin `0.3.1` requires Tree Ring Memory CLI **>= 0.14.0**. The minimum is
 intentional: v0.14 adds receipt-backed harness readiness on top of the v0.13
 schema-v3, coordinated-write, and idempotency contracts used by this guidance.
 
+The public ZIP is a skills-only package. It intentionally omits
+`interface.screenshots`, which OpenAI's ZIP ingestion does not accept for this

 It does not run a background service, scrape chats, or capture transcripts.
 The active agent chooses when a memory action is useful, source-linked, and
 privacy-safe.

 ## Release Notes
 
-Initial OpenAI submission of the v0.14-compatible skills-only package. It adds
-runtime preflight, receipt-backed harness readiness, exact non-active states,
-same-host coordination rules, and explicit privacy-safe fallback when local
-execution is unavailable. The plugin has no MCP server, hosted service,
-credentials, telemetry, or reviewer account requirement.
+Version 0.3.1 of the v0.14-compatible skills-only package removes
+`interface.screenshots`, which OpenAI ZIP ingestion does not allow for
+skills-only plugins. It retains runtime preflight, receipt-backed harness
+readiness, exact non-active states, same-host coordination rules, the logo and
+composer icon, and explicit privacy-safe fallback when local execution is
+unavailable. The plugin has no MCP server, hosted service, credentials,
+telemetry, or reviewer account requirement.
