 - 本轮补充：microcompact disk cache loader 现在会把 `value` 字段中的 text content-block object 识别为 direct summary payload，同时继续从同一 `value` object 中补 digest、version、timestamp 等 cache metadata，避免 `value` 作为 summary/cache wrapper 双义字段时丢摘要或 sidecar 信息。

 - `internal/session`: prompt-history pasted-content containers now accept aliases such as `pastedContent`/`pasted_content`, `pasteContents`/`paste_contents`, `pastes`, and `attachments`/`attachment`, matching interaction script fixture shapes for runtime and stored history.
 - `internal/session`: prompt-history pasted image loading now accepts content-block-style `source`/`imageSource` objects, nested JSON:API/GraphQL-style source wrappers, data URL aliases, and source URL/URI/cache-path aliases; stored image entries with inline source data or a current-session image-cache file now restore base64 content into prompt image blocks instead of keeping only metadata, including same-ID cache fallback, media-type inference when history metadata omits the original MIME type, symlink escape guards before reading cached image bytes, and restored path re-indexing for later image metadata/source lookup.
 - `internal/compact`: microcompact disk cache loading now accepts broader summary-like direct and provider aliases including `body`, `markdown`, `description`/`details`, `finalSummary`, `summaryContent`, `plainText`/`displayText`, `answerText`, `refusal`, `resultText`, `completionText`, `responseText`, and `messageText`; provider summary recovery also follows wrapper-only `value`/`payload`/`data` chains without failing on non-summary metadata, preserving visible summaries through nested cache entries, JSON:API/resource envelopes, and provider-style response wrappers.
+- `internal/compact`: microcompact provider and cache summary extraction now unwraps inline fenced JSON payloads where the fence language and JSON object are on the same line, so SDK/model outputs no longer preserve the whole code fence as visible summary text.
