Did a quick run through as I'm outside right now, so just some preliminary comments, thanks!

More of an overarching question - do you think it makes sense to frame it just as a maze minigame rather than a robot minigame? The idea of having it be a robot seems more context dependent within SA game, but as a module (which is published for not just Source Academy but for Source as a whole), it might be a nice idea to frame it as a general purpose maze minigame.
(Asking because this would necessitate some variable name changes)

Restructures src/bundles/maze and src/tabs/Maze to match the per-module package layout (package.json, manifest.json, tsconfig.json, src/) introduced by the yarn workspaces transition on master, and updates the tab to use the current defineTab/getModuleState helpers and package-based imports instead of the removed src/typings path and relative cross-package imports.
Replace throw new Error() with GeneralRuntimeError so thrown errors satisfy the throw-runtime-error rule, drop redundant type assertions, and apply eslint --fix for remaining stylistic warnings. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Addresses lhw-1's PR review comment asking to allow the animation speed to change, mirroring the existing set_border_color/set_border_width pattern. Adds set_animation_speed() and covers it with unit tests. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
vi.mock's factory return type is checked against the module's real
export shape, so the mocked js-slang/context default needed to be a
full Context, not just { moduleContexts }. This was failing yarn tsc
in CI (TS2769) though it silently passed in local installs that
weren't in sync with a clean yarn.lock install.

AreaTest previously extended a loose Test interface ({ type: string;
test: Function }) that already accepted AreaTest-shaped object
literals structurally, so the `as AreaTest` cast at its only call
site was flagged as unnecessary and removed, leaving AreaTest as
dead code. Flipping the relationship to `type Test = AreaTest` keeps
AreaTest referenced and lets helpers/tests.ts's `type === 'area'`
check actually narrow to AreaTest's typed test() signature instead
of a bare Function.

set_animation_speed() accepted 0/negative/NaN values with no validation. In the Maze tab's animation loop, a speed of 0 means `distance <= animationSpeed` never resolves (robot frozen forever), and a negative speed reverses the per-tick step so distance grows unboundedly — both permanently softlock the tab. Guard against non-finite and non-positive speeds with GeneralRuntimeError, matching this file's existing validation pattern. Separately, the rotate case's per-tick step was hardcoded to 0.1 rad regardless of animationSpeed, so turning pace stayed fixed while movement pace became configurable. Scale it by the same factor (0.05 rad/unit, calibrated so the default animationSpeed of 2 reproduces the previous 0.1 rad/tick) so move/turn pacing stays consistent.

Stop after the nearest obstacle collision.
collisions is sorted by ascending distance. When two obstacles are within the requested movement distance, the first obstacle sets a safe distance, but each later obstacle overwrites it with a larger distance. The robot can finish past the nearest wall.

Use a perpendicular vector for the side-ray origins.
Line 488 uses (dy, dx) as the offset vector. This vector is not perpendicular to the heading (dx, dy) except at axis-aligned rotations. At a 45-degree rotation, the two side rays start in front of and behind the robot instead of on its sides. An obstacle that contacts the robot laterally can then be missed.

Use a half-open edge rule for point containment.
Line 116 counts both edges when the ray passes through a vertex. For a triangle with vertices (0, 0), (2, 1), and (0, 2), the interior point (0.5, 1) produces two intersections at (2, 1) and returns false. area_of_point then cannot find the area, so get_color can return no color for an interior point.

Use -Math.PI as the lower bound.
rotate() logs rotations normalized to [-Math.PI, Math.PI]. This check currently adds 2 * Math.PI to every ordinary positive intermediate angle below Math.PI, which can disrupt interpolation near the wraparound. Change the bound so playback preserves the normalized range and final target snap.
