+# Tarcza zewnętrzna — weryfikacja
+
+Godot 4.7.2, 2026-10-26.

+- PASS: `tests/abilities/auxiliary_shield_test.tscn`: odblokowanie w laboratorium, aktywne rozszerzenie bez addonów, koszt 70% maksymalnej energii i blokada przy niewystarczającym zapasie, pojemność 50% maksymalnych tarcz w chwili aktywacji. Osobna pula nie regeneruje się i nie nakłada; obrażenia zużywają ją przed zwykłymi tarczami, a nadmiar przechodzi dalej na tarcze/kadłub. Prawidłowy cooldown, reset, dokowanie i wyłączenie przez Przekierowanie zasilania. Pociski i lasery zatrzymują się na większym obwodzie również przy pustych tarczach głównych. Zwykłe technologie tarcz nie zużywają odnowienia, gdy całe trafienie pochłonęła warstwa zewnętrzna.
+- PASS: `tests/items/shield_collision_test.tscn`: dotychczasowe pociski, lasery, tarcze i przeszkody działają poprawnie.
+- PASS: `tests/previews/auxiliary_shield_preview.tscn`: rzeczywista aktywacja rozszerzenia w scenie gry, podgląd obu warstw, ikona i odczyt dodatkowej pojemności, 1280×720.
+- PASS: `git diff --check`.
+
+Nowa warstwa ma promień 1,45× promień zwykłej tarczy. Efekt: fioletowy obwód i siatka sześciokątów, osobne błyski trafień oraz licznik punktów osłony.
+
+Ikona: `assets/icons/extensions/auxiliary_shield.png`, wygenerowana wbudowanym image_gen z przezroczystym tłem. Prompt: `assets/icons/extensions/auxiliary_shield_prompt.md`.

+# Działka zewnętrzne — weryfikacja
+
+Godot 4.7.2, 2026-10-26.
+
+- PASS: `tests/items/external_turret_test.tscn`. Odblokowanie w laboratorium; dokładnie połowa obrażeń działka maszynowego przy tym samym losowaniu na poziomach 1, 5, 30, 120 i 1000; 49 amunicji nie wystarcza; rozstawienie pobiera dokładnie 50 pomimo Oszczędnego magazynka III. Jedno kliknięcie rozstawia jedno działko, przytrzymanie nie rozstawia kolejnych. Działko zostaje w swoim miejscu po odlocie statku, zachowuje amunicję bez celu, wykrywa cel i oddaje dokładnie 50 rzeczywistych pocisków. Zweryfikowano obrażenia przeciwnika, brak dodatkowego pobierania amunicji i usunięcie po wyczerpaniu magazynka/dokowaniu. Zmiana lub zdjęcie broni nie zmienia już rozstawionego działka.
+- PASS: `tests/ships/laboratory_loot_test.tscn`. Broń nie występuje w początkowych łupach i pojawia się po badaniu; brak duplikatów w puli.
+- PASS: `tests/previews/external_turret_preview.tscn`. Podgląd grafiki i pocisków w działającej scenie gry, 1280×720.
+- PASS: `git diff --check`.
+
+Ikona i przezroczysty sprite powstały przez wbudowane image_gen. Pliki oraz prompty opisano w `assets/icons/external_turret_prompts.md`.

+- PASS: `tests/captain/new_skills_test.tscn` — 14 skills; five new icons; training; all three ranks; laboratory timing; normal/radiation ammunition production and mineral costs; enemy bounty; missile cooldown; emergency repair resource checks, docking, cooldown, full hull and repair cap.
+- PASS: `tests/ships/laboratory_loot_test.tscn` — starting plasma-only weapon pool, locked extensions, all research unlocks and no duplicate loot entries.
+- PASS: `tests/previews/new_captain_skills_preview.tscn` — real game UI, all 14 owned skills, new choices, F1 assignment, emergency repair on the actual ship, and screenshots at 1280×720.
+- PASS: `git diff --check`.
+
+Additional older regression scenes do not pass:
+
+- `tests/abilities/missile_system_test.gd:20` expects movement into weapon slot 2 without unlocking that slot. This change does not alter slot unlock rules.
+- `tests/items/crafting_recipes_test.gd:54` expects immediate mineral credit after asteroid destruction; its null asteroid sprite also fails in `asteroid_destruction_effect.gd:8`. This change does not alter asteroid reward or debris behavior. The recipe transactions before that section succeed.
+
+The headless editor/runtime also reports sandbox access warnings for external Godot/MCP settings directories. New skill tests and the rendered preview complete successfully.
+
+Icons were generated with the built-in image_gen tool. Original prompts are saved in `assets/icons/captain/new_skills_prompts.md`.

+# Laser pulsacyjny — weryfikacja
+
+Godot 4.7.2, 2026-10-26.
+
+- PASS: `tests/items/pulse_laser_test.tscn`. Odblokowanie w laboratorium, 50% szansy na pełne ominięcie tarcz, granica losowania i zgodność z orbem przebicia. Przy identycznych losowaniach na poziomach 1, 5, 30, 120 i 1000 broń zadaje 70% obrażeń lasera wiązkowego i zużywa 130% jego energii. Pojedyncze czerwone impulsy lecą z prędkością 1500 px/s (bazowo strzał co 0,2 s). Sprawdzone przesunięcie o 60 px w 0,04 s, brak natychmiastowych obrażeń i naliczanie trafienia dopiero po dotarciu do tarcz lub kadłuba; współdziałanie z technologią podwójnego trafienia i brak strzału przy zbyt małej ilości energii.
+- PASS: `tests/items/external_turret_test.tscn`. Brak regresji obrażeń działek zewnętrznych po ujednoliceniu mnożników obrażeń przedmiotów.
+- PASS: `tests/previews/pulse_laser_preview.tscn`. Podgląd dwóch osobnych, krótkich czerwonych pocisków w scenie gry, 1280×720. Plik: `artifacts/pulse_laser_flying_preview.png`.
+- PASS: `tests/items/shield_collision_test.tscn`. Zwykłe pociski i lasery nadal zatrzymują się na tarczach; osłony fizyczne i trafienia styczne działają poprawnie.
+- PASS: `tests/items/laser_energy_regeneration_test.tscn` (600 klatek fizyki, fixed-fps 60). Zwykły laser nadal prawidłowo zużywa energię podczas 10 s strzelania.
+- PASS: `tests/items/weapon_icon_transparency_test.tscn`. Wszystkie 11 ikon broni ma przezroczyste tło i widoczną grafikę. Pięć edytowanych plików i prompt opisano w `assets/icons/weapon_background_removal.md`.
+- PASS: `git diff --check`.
+
+Ikona powstała przez wbudowane image_gen. Plik `assets/icons/pulse_laser.png`, prompt `assets/icons/pulse_laser_prompt.md`; tło usunięto zgodnie z późniejszą prośbą. Lecące impulsy rysowane są przez istniejący system pocisków. Zwykłe i radiacyjne lasery zachowują dotychczasowe wiązki.

+Use case: stylized-concept. Asset type: square inventory extension icon for a science fiction spaceship game, isolated on truly transparent alpha background. A compact silver gunmetal and brass shield generator with glowing violet and cyan capacitor coils, projecting two concentric holographic protective domes: a smaller cyan shield inside a visibly larger violet hexagonal energy barrier. Centered premium detailed 3D game item render, strong readable silhouette filling 80 percent of square, matching realistic silver/brass sci-fi equipment icons. Keep all parts within canvas. No floor, no background, no text, no numbers, no border. Soft translucent energy glow allowed around the generator.

+Prompt dla każdej z pięciu edycji (oryginalna ikona jako edit target):
+
+Use case: background-extraction. Edit target: the provided inventory weapon icon. Remove ONLY the dark navy/black background and its vignette. Output actual transparent alpha background, including spaces around and between mechanical parts. Preserve the exact same weapon, silhouette, position, crop, scale, metallic textures, colors, lighting, detail and luminous accents. Keep attached flames/energy/thruster light as soft translucent glow where present. Do not redesign, add, remove or reposition any part of the weapon; do not add a floor, shadow, outline or replacement backdrop. Preserve the square canvas composition.
