⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Dependency install step can silently succeed after total failure.

|| true makes this step pass even if both install paths fail, so later steps run in an invalid environment and CI can still appear green.

⚠️ Potential issue | 🟠 Major | 🏗️ Heavy lift

Workflow does not match the stated project CI target.

This workflow validates Python (flake8, mypy, pytest) while the PR objective says CI should target a Vue/TypeScript project. As written, it won’t gate the intended stack.

In @.github/workflows/python-ci.yml around lines 1 - 33, The workflow currently
runs a Python "test" job using steps named "Lint with flake8", "Type check with
mypy", and "Run tests" which doesn't match the PR's Vue/TypeScript target;
replace the Python-specific steps and tools with Node/TypeScript equivalents:
change the job to install Node using actions/setup-node, run npm/yarn install,
run ESLint for linting (replace "Lint with flake8"), run the TypeScript compiler
or tsc/tsserver for type checks (replace "Type check with mypy"), and run the
project's test runner (jest/vitest) in lieu of "Run tests"; update the matrix to
use Node versions instead of python-version and adapt the step names (e.g., "Set
up Node", "Install dependencies", "Lint with ESLint", "Type check with tsc",
"Run tests with jest") so the CI actually validates the Vue/TypeScript stack.

Type-check and test failures are currently masked.

Both steps convert failures into success (|| echo ...), which defeats CI quality gates.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Guard against prototype pollution in parameter iteration.

The for...in loop iterates over all enumerable properties including inherited ones from the prototype chain. This could inadvertently add unexpected properties to the URL search parameters if params has inherited properties.

🛡️ Proposed fix using Object.entries() 
-        for (const param in params) url.searchParams.set(param, params[param]);
+        for (const [param, value] of Object.entries(params)) url.searchParams.set(param, value);

Alternatively, use Object.keys():

-        for (const param in params) url.searchParams.set(param, params[param]);
+        for (const param of Object.keys(params)) url.searchParams.set(param, params[param]);

In `@src/composables/useApi.js` at line 6, The iteration over params using "for
(const param in params)" in useApi.js can include inherited properties; change
it to iterate only own keys (e.g., use Object.keys(params) or
Object.entries(params)) or check hasOwnProperty before calling
url.searchParams.set so only own properties are added; update the loop that sets
URL search params in the useApi (or the function that constructs the URL) to use
Object.keys/entries or an explicit ownership check.
