From 9d88598cd1b0968ee18c89fd703aa9718d60ad30 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 29 Mar 2026 20:20:42 +0000 Subject: [PATCH 1/3] fix: reorder test data generation and fix CLI prompts - Moved test data generation and insertion logic before `helpers::prompt_microstructure_variable` in `tests/integration_test.rs` so data is present for min/max calculations. - Modified `prompt_microstructure_variable` and `prompt_cutoff_value` in `src/helpers.rs` to use `print!` and `io::stdout().flush().unwrap()` to properly render prompts inline before waiting for user input, fixing issues with hidden/delayed standard output on interactive shells.

Uses the default `objects_s_100000_below` and `objects_s_100000_above` tables created implicitly by the initial migrations to receive the test data. - Ensures the default partitions are successfully detached using their exact migration names (`objects_s_100000_below`) before the user's explicit partition request (`180000.0`) runs, preventing `relation does not exist` test failures while preserving the 200,000 inserted rows for the prompt queries. - Removes locally compiled scratchpad binaries and extraneous debugging source files from the workspace.
