Summary

CodeRabbit's review 5541840681 on #82 left three test nitpicks for tests/platformer_stage_clear.gd. I merged #82 before addressing them; this PR applies all three. It is test-only.

• Lines 34–36: wait out the stinger's length and assert it stops after one playback, so a copied finished-signal restart would fail the suite. The leave-the-results check now starts the stinger again before pressing the button, so it still proves the stop.
• Lines 41–44: assert game.finished and not game.won_run right after the fall, proving the knockout path ran before checking the stinger.
• Lines 43–44: wait 3.6 s, past the 3.5 s knockout cutaway and the shared results reveal, before asserting the stinger stayed silent.

Part of #44.

Testing

Summary by CodeRabbit

• Tests
  • Expanded stage-clear and knockout checks to verify result timing and confirm the stinger stops or remains stopped as expected. The checks also confirm the stinger plays once after a win, stops when leaving the results screen, and does not play after a knockout.

📝 Walkthrough

This test-only change expands coverage of the platformer stage-clear stinger. It checks that playback starts once and stops, that leaving results stops playback, and that the knockout path reaches results without playing the stinger.

Changes: Platformer stage-clear tests

Layer / File(s)	Summary
Stinger playback and knockout checks hoppys-adventure-arcade/tests/platformer_stage_clear.gd	The test monitors playback through the stinger’s full length and checks that it starts once and stops. It starts the stinger before leaving results and checks that playback stops. After a fall, it checks that the game finished without a win and that the stinger remains silent over the 3.6-second knockout and results interval.

Review details

Systems and components

• observed — hoppys-adventure-arcade (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in hoppys-adventure-arcade/tests/platformer_stage_clear.gd: When the stinger resource is unavailable, the test now reports its result and exits. Otherwise, each level’s finish check watches playback from stopped for 0.5 seconds, then watches for the stream’s full length and checks that it started once and stopped. This replaces the fixed 0.5-second wait with playback monitoring.
• observed — Modified behavior in hoppys-adventure-arcade/tests/platformer_stage_clear.gd: Before emitting the return-to-menu button, the test starts the stinger and checks that leaving results stops playback.
• observed — Modified behavior in hoppys-adventure-arcade/tests/platformer_stage_clear.gd: After triggering a fall, the test checks that the game is finished but the run was not won, then watches 3.6 seconds of knockout and results playback and verifies the stinger never played. This replaces the fixed 0.5-second wait and single stopped-state check.
• observed — Modified behavior in hoppys-adventure-arcade/tests/platformer_stage_clear.gd: The run now calls finish() for final reporting and unpausing. The added watch() samples playback each frame, including while paused, counts starts from stopped or playback-position resets, and records whether playback occurred.

hoppys-adventure-arcade/tests/platformer_stage_clear.gd: 2

39-40: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Observe playback starts during the win interval.

The current assertion checks only the terminal playing state. A second stage_clear.play() during the initial 0.5-second wait can finish before the assertion and still pass. Count or otherwise observe stinger playback starts and assert that the win path starts it exactly once. This is a focused coverage improvement for the duplicate-start regression; _reveal_results(0.35) does not currently start the stinger.

Update the stage-clear test around `game.stage_clear` to observe playback starts
during the win interval and assert the win path starts the stinger exactly once,
rather than relying only on its final `playing` state.

54-55: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Keep an early knockout-path playback check.

The knockout assertion now checks only after the 3.6-second cutaway. The stage-clear fixture lasts about 4.74 seconds, so playback that starts during knockout normally remains active at the final sample. However, a transient start that another transition stops before 3.6 seconds can still escape detection. Retain a check near knockout entry, or sample playback during the cutaway, to preserve coverage of the knockout interval.

@coderabbitai review 5541968522: both nitpicks are applied in 69f4967. A new watch(player, seconds) helper samples stage_clear on every frame, paused or not, and counts playback starts (from stopped, or a jump back to the start).

• Lines 39–40: the win path must start the stinger exactly once across the 0.5 s window and the stinger's full length, then stop.
• Lines 54–55: every frame of the 3.6 s knockout and results window is sampled, and the stinger must never be playing, so a transient start can't slip through.

22 checks pass locally.

@esthor I checked hoppys-adventure-arcade/tests/platformer_stage_clear.gd. Both nitpicks are covered:

• The win path counts playback starts across both observation windows and requires exactly one start, followed by a stop.
• The knockout path confirms game.finished and not game.won_run, then samples playback each frame for 3.6 seconds and requires silence throughout.

I did not rerun the tests. The 22 passing checks remain your reported local result. No further changes are needed for these two points.
