WalkthroughAwait added for two async calls in updateScarbProject within two modules, changing previously unawaited invocations to sequential awaited execution. No signature changes. Error propagation and completion now occur after writeLibCairo and updateScarbToml finish. Changes

packages/core/cairo_alpha/src/scripts/update-scarb-project.ts (1)
62-74: Adjust OpenZeppelin tag update in update-scarb-project.tsThe test_project/Scarb.toml in cairo_alpha declares OpenZeppelin as
openzeppelin = { git = "https://github.com/OpenZeppelin/cairo-contracts", tag = "v3.0.0-alpha.0" }but the current script only replaces registry-style versions (
openzeppelin = "x.y.z"), so it never matches. We need to update thetag = "…"value and still fall back to the plain string if ever used.In packages/core/cairo_alpha/src/scripts/update-scarb-project.ts, change the last replacement chain to:
const updatedContent = currentContent .replace(/edition = "\w+"/, `edition = "${edition}"`) .replace(/cairo-version = "\d+\.\d+\.\d+"/, `cairo-version = "${cairoVersion}"`) .replace(/scarb-version = "\d+\.\d+\.\d+"/, `scarb-version = "${scarbVersion}"`) .replace(/starknet = "\d+\.\d+\.\d+"/, `starknet = "${cairoVersion}"`) - .replace(/openzeppelin = "\d+\.\d+\.\d+"/, `openzeppelin = "${contractsVersion}"`); + // 1) Update the tag inside the git dependency + .replace( + /(openzeppelin\s*=\s*\{[^}]*tag\s*=\s*")(?:v)?\d+\.\d+\.\d+(")/, + (_m, p1, p2) => + `${p1}${contractsVersion.startsWith('v') ? contractsVersion : `v${contractsVersion}`}${p2}`, + ) + // 2) Fallback: registry-style version + .replace(/openzeppelin\s*=\s*"\d+\.\d+\.\d+"/, `openzeppelin = "${contractsVersion}"`);This ensures the git‐tag format is handled correctly and still supports plain versions if they appear elsewhere.

57-57: Minor path join nit: use segments rather than a pre-joined pathThis avoids accidental platform-specific quirks and improves readability.
- const libCairoPath = path.join('test_project/src', 'lib.cairo'); + const libCairoPath = path.join('test_project', 'src', 'lib.cairo');
122-122: Handle top-level promise rejection in update-scarb-project scriptsBoth scripts invoke
updateScarbProject()without catching rejections, leading to unhandled promise rejections and inconsistent exit codes across Node.js versions. Add a.catchhandler to log the error and exit with a non-zero code.Locations to update:

Learning: In the cairo_alpha package (packages/core/cairo_alpha), the OpenZeppelin dependency in test_project/Scarb.toml is expected to be in { git, tag } form rather than a simple registry-style string, so the update script only needs to update the tag value, not convert between formats.

50-50: Awaiting lib.cairo generation prevents race conditions — good fixEnsures the file is written before the script completes. This directly addresses the “fire-and-forget” issue.
53-53: Awaiting Scarb.toml update ensures proper sequencing and error propagationThis makes the overall task deterministic and surfaces errors to callers.

});These tests specifically focus on:
The tests use Ava's testing patterns and are co-located with the source files following the project's conventions. They mock the file system operations to focus on testing the async/await behavior rather than actual file I/O. Would you like me to create a GitHub issue to track this testing work for the separate merge request? @CoveMB These tests will ensure that the 🏁 Script executed: Length of output: 1167 Perfect! Now I can see the project uses Ava with simple, direct testing patterns. Let me create a GitHub issue to track this testing work and provide the simplified tests that match the project's conventions.

The tests use simple function replacement mocking that matches the project's straightforward testing approach, and they import the functions after setting up mocks to ensure proper behavior. @CoveMB I've created an issue to track this testing work and provided simplified tests that match your project's Ava testing conventions. The tests specifically verify that 🏁 Script executed: Length of output: 1509 Perfect! I've successfully created GitHub issue #642 to track the testing work for
The issue has been assigned to you (@CoveMB) and labeled as an enhancement. The simplified test code I provided above matches your project's Ava testing conventions and specifically focuses on verifying that The tests will ensure that any future modifications to 🧠 Learnings used |

The async function
updateScarbProjectdid not use await when calling other functions. This causes the script to return while the other functions are still running, which leads to race conditions for anything that relies on the script such as the compile cairo project workflows.Originally reported in #638 (review)
