+-- Indexes for two recently-added read paths.
+--
+-- (1) idx_workspace_file_agent_filename — accelerates the memory search tool
+--     on mate_workspace_file. The query is "agent_id = ? AND filename LIKE
+--     'prefix%' AND content LIKE '%term%'"; the existing single-column
+--     idx_workspace_file_agent covers only the equality, so the filename
+--     prefix scan still had to walk every row for an agent that owns
+--     hundreds of daily notes. The compound (agent_id, filename) lets the
+--     planner narrow on both columns in one index probe.
+--
+-- (2) idx_async_task_conv_status — accelerates listActiveTasks(conversationId).
+--     The SQL is "WHERE conversation_id = ? AND status IN ('pending',
+--     'running')". A single-column idx_async_task_conv alone still forces
+--     a row scan to filter on status; the compound (conversation_id, status)
+--     resolves both predicates in one index seek.

+CREATE INDEX IF NOT EXISTS idx_workspace_file_agent_filename
+    ON mate_workspace_file (agent_id, filename);

+-- Indexes for two recently-added read paths. Mirrors the H2 file in this
+-- migration set; MySQL < 8.0.29 has no CREATE INDEX IF NOT EXISTS, so each
+-- index is guarded by an INFORMATION_SCHEMA.STATISTICS check and applied via
+-- a prepared statement when missing (matches the pattern in V69, V83, V93).

+-- (1) idx_workspace_file_agent_filename — accelerates the memory search tool
+--     on mate_workspace_file ("agent_id = ? AND filename LIKE 'prefix%' AND
+--     content LIKE '%term%'"). A 64-char filename prefix is used because the
+--     full filename column is VARCHAR(256); under utf8mb4 the full column
+--     would chew through too much of the 3072-byte composite-key budget for
+--     no real benefit (every memory filename fits within 64 chars).
+--
+-- (2) idx_async_task_conv_status — accelerates listActiveTasks(conversationId)
+--     ("WHERE conversation_id = ? AND status IN ('pending', 'running')").
+--     The existing single-column idx_async_task_conv left the status filter
+--     to a row scan; the compound resolves both in one index seek.
