 - Memory/OpenAI-compatible: add optional `memorySearch.inputType`, `queryInputType`, and `documentInputType` config for asymmetric embedding endpoints, including direct query embeddings and provider batch indexing. Carries forward #63313 and #60727. Thanks @HOYALIM and @prospect1314521.
 - Ollama/memory: add model-specific retrieval query prefixes for `nomic-embed-text`, `qwen3-embedding`, and `mxbai-embed-large` memory-search queries while leaving document batches unchanged. Carries forward #45013. Thanks @laolin5564.
 - Plugins/providers: move pre-runtime model-id normalization, provider endpoint host metadata, and OpenAI-compatible request-family hints into plugin manifests so core no longer carries bundled-provider routing tables. Thanks @codex.
-- Plugins/config: deprecate direct plugin config load/write helpers in favor of passed runtime snapshots plus transactional mutation helpers with explicit restart follow-up policy. Thanks @codex.
+- Plugins/config: deprecate direct plugin config load/write helpers in favor of passed runtime snapshots plus transactional mutation helpers with explicit restart follow-up policy, scanner guardrails, runtime warnings, and revision-based cache invalidation. Thanks @codex.
 - Plugins/install: allow `OPENCLAW_PLUGIN_STAGE_DIR` to contain layered runtime-dependency roots, resolving read-only preinstalled deps before installing missing deps into the final writable root. Fixes #72396. Thanks @liorb-mountapps.
 - Control UI: add a raw config pending-changes diff panel that parses JSON5, redacts sensitive values until reveal, and avoids fake raw-edit callbacks when opening the panel. Refs #39831; supersedes #48621 and #46654. Thanks @JiajunBernoulli and @BunsDev.
 - Control UI: polish the quick settings dashboard grid so common cards align across desktop, tablet, and mobile layouts without wasting horizontal space. Thanks @BunsDev.

+Internal OpenClaw runtime code has the same direction: load config once at the CLI, gateway, or process boundary, then pass that value through. Successful mutation writes refresh the process runtime snapshot and advance its internal revision; long-lived caches should key off the runtime-owned cache key instead of serializing config locally.

+Prefer the shared plugin runtime mock from the repo test helpers when testing
+bundled plugins. Its deprecated `runtime.config.loadConfig()` and
+`runtime.config.writeConfigFile(...)` mocks throw by default so tests catch new
+usage of compatibility APIs. Override those mocks only when the test is
