From 1ba6894d1fc027b306b0f573675dfe43cb5acd12 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 17 Mar 2026 13:37:02 +0000 Subject: [PATCH 1/2] Add dynamic progress bar for quiet mode in CLI When running the bitcoin trading simulation in --quiet mode, the tool previously printed no output until the end, creating a "black box" UX for long-running jobs. This commit introduces a dynamic progress bar that overwrites itself using \r when the output is an interactive terminal (`sys.stdout.isatty()`). It also fixes a bug where buy and sell signals were incorrectly printing even when --quiet was passed. A journal entry was added to .Jules/palette.md to record this CLI UX pattern.

The `COPY` directive has been updated to use the correct relative path (`COPY NumberGuess/NumberGuess.cpp .`), resolving the "not found" build error. 2. **Terraform:** The `hashicorp/setup-terraform` GitHub action step `terraform plan` was failing with "No configuration files". Terraform requires at least one configuration file (even if empty) to run `init` and `plan`. An empty `main.tf` has been added to the root directory containing `terraform {}` to satisfy this requirement and allow the CI pipeline to complete successfully.
