-- 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);
CREATE INDEX IF NOT EXISTS idx_async_task_conv_status
ON mate_async_task (conversation_id, status);

-- 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.
