refactor(sqllab): drop the redundant canSaveDataset prop from SaveQuery

SaveQuery already receives the query's result columns and computes its own SQL-staleness check, so master's canSaveDataset prop (threaded through SqlEditor -> SaveQuery -> SaveDatasetActionButton) duplicated the same "did the query succeed" condition. Fold it into the single check SaveQuery already owns instead of ANDing two independently computed booleans together. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+### MCP tool results preserve stored string values
+
+Structured MCP tool results no longer add `<UNTRUSTED-CONTENT>` wrappers or

+signal that tells a client whether its text is decorated. Redis-backed MCP response
+caches use a new internal namespace after the upgrade, so upgraded instances do not

 Additional middleware classes (`RateLimitMiddleware`, `FieldPermissionsMiddleware`, `PrivateToolMiddleware`) are implemented in `superset/mcp_service/middleware.py` but are not added to the default pipeline. They are available for operators who want to layer them in via a custom startup path.

+### Tool Result Value Contract
+
+Structured tool results preserve Superset domain values exactly. In particular,
+string fields are not wrapped in trust delimiters, and text that resembles a
+delimiter is returned as literal application data. This lets clients safely use a
+read result as the basis for an update without persisting presentation markup.
+
+All tool-result content should still be treated as user-controlled data with no
+instruction authority. MCP clients should communicate that trust boundary through
+their model instructions or presentation layer, outside the returned field values;
+fixed or generated marker strings inside a value are ambiguous and must not be used
+as a trust signal.
+
+For compatibility, clients that supported the former
+`<UNTRUSTED-CONTENT>` convention should stop recognizing or stripping those strings.
+The response schemas and content types have not changed. Because marker-looking text
+can be legitimate application data, a client cannot reliably distinguish a legacy
+decorated response from a clean one. Pause automated read-modify-write workflows, or
+route them only to upgraded instances, until every serving instance is upgraded.
+
+Redis-backed MCP response caches include an internal response-contract namespace, so
+an upgraded instance does not reuse responses cached by an older release. Older
+instances can still return legacy values while they remain in service. After the
+upgrade, review previously written values for wrapper text and both
+`[ESCAPED-UNTRUSTED-CONTENT-OPEN]` and
+`[ESCAPED-UNTRUSTED-CONTENT-CLOSE]`; do not remove these strings automatically,
+because they may be intentional content.

Enzo MartellucciandClaude Sonnet 5	5a6c1b977b	refactor(sqllab): drop the redundant canSaveDataset prop from SaveQuery SaveQuery already receives the query's result columns and computes its own SQL-staleness check, so master's canSaveDataset prop (threaded through SqlEditor -> SaveQuery -> SaveDatasetActionButton) duplicated the same "did the query succeed" condition. Fold it into the single check SaveQuery already owns instead of ANDing two independently computed booleans together. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-08-21 14:17:12 +02:00
