 - CLI/config: keep JSON dry-run patches validating touched channel configuration against bundled channel schemas even when the patch only contains SecretRef objects.
 - Plugins/tools: keep disabled bundled tool plugins out of explicit runtime allowlist ownership and fall back from loaded-but-empty channel registries to tool-bearing plugin registries, so Active Memory can use bundled `memory-core` search/get tools even when `memory-lancedb` is disabled. Fixes #76603. Thanks @jwong-art.
 - Plugins/install: run `npm install` from the managed npm-root manifest so installing one `@openclaw/*` plugin preserves already installed sibling plugins instead of pruning them. Fixes #76571. (#76602) Thanks @byungskers and @crpol.
+- Plugins/tools: restore on-demand registry load for path-based plugins (origin "config") so tool factories registered via `plugins.load.paths` are resolved at agent request time when no pre-warmed channel registry is present; prevents "unknown method" errors after gateway startup. Fixes #76598. Thanks @hclsys.
 - Channels/QQ Bot: resolve structured `clientSecret` SecretRefs before QQ token exchange, expose the QQ Bot secret contract to secrets tooling, and reject legacy `secretref:/...` marker strings. (#74772) Thanks @xialonglee.
 - Agents: keep active streamed provider replies alive by refreshing guarded fetch timeouts on raw body chunks and surface true prompt stream timeouts as explicit errors instead of partial assistant fragments. Fixes #76307. (#76633) Thanks @MkDev11.
 - Plugins/externalization: keep official ACPX, Google Chat, and LINE install specs on production package names, leaving beta-tag probing to the explicit OpenClaw beta update channel. Thanks @vincentkoc.
