     Prefer `getSessionEntry(...)`, `listSessionEntries(...)`, `patchSessionEntry(...)`, or `upsertSessionEntry(...)` for session workflows. These helpers address sessions by agent/session identity so plugins do not depend on the legacy `sessions.json` storage shape. Use `preserveActivity: true` for metadata-only patches that should not refresh session activity, and `replaceEntry: true` only when the callback returns a complete entry and deleted fields must stay deleted.
 
-    For transcript reads and writes, import `openclaw/plugin-sdk/session-transcript-runtime` and use `resolveSessionTranscriptIdentity(...)`, `resolveSessionTranscriptTarget(...)`, `readSessionTranscriptEvents(...)`, `appendSessionTranscriptMessageByIdentity(...)`, `publishSessionTranscriptUpdateByIdentity(...)`, or `withSessionTranscriptWriteLock(...)` with `{ agentId, sessionKey, sessionId }`. These APIs let plugins identify a transcript, read its events, append messages, publish updates, and run related operations under the same transcript write lock. Pass `sessionFile` only when adapting code that already receives an active transcript artifact and needs each helper to operate on that same artifact.

Passing `sessionFile`, using `resolveSessionTranscriptLegacyFileTarget(...)`, or importing low-level `appendSessionTranscriptMessage(...)` / `emitSessionTranscriptUpdate(...)` from `openclaw/plugin-sdk/agent-harness-runtime` is deprecated; those paths exist only for legacy code that already receives an active transcript artifact.
 
-    `loadSessionStore(...)`, `saveSessionStore(...)`, `updateSessionStore(...)`, and `resolveSessionFilePath(...)` are compatibility helpers for plugins that still intentionally depend on the legacy whole-store or transcript-file shape. New plugin code must not use those helpers, and existing callers should migrate to entry helpers.
