Aurora Application Guide Open current lane build Project guide

Aurora Application Guide

A generated application reference for Aurora Galactica: audio cues by context, visual atmosphere themes, and the developer-facing presentation controls that shape the live game presentation.

Guide focus: Keep Aurora's atmosphere, sound, and presentation coherent as one application-owned system while preserving a clean boundary with Platinum, use the Galaga cue matrix to map real reference clips against Aurora states, and distinguish clearly between Aurora's own synthetic mix, the Galaga-style synthetic approximation, and the new runtime reference-audio mode that plays actual extracted Galaga clips.

Sound buttons use a hidden same-origin preview frame running the current lane build, so the page plays Aurora, Galaga synth, and Galaga reference-runtime cues through the real in-game audio engine instead of a separate mock player. Reference buttons play extracted Galaga clips from the curated artifact library. If a button seems silent, check browser audio permission and the game's mute preference in the current lane build.

Audio Event Matrix

A refreshed event-by-event timing map for Aurora against the current Galaga alignment work. Use this to review what each event is, when the sound should land, which cue or reference excerpt we use, and what should interrupt or protect it.

Game Event	Timing Of Activity	Audio Name / Status	How It Starts / Stops	Comment / Gap	Review Actions
Front-door navigation tick frontDoor	Immediate on menu move / focus change.	`uiTick` Implemented	Start: Initiated by shell navigation events so the shell feels responsive before gameplay starts. Stop: One-shot cue. No explicit stop rule.	Application-owned shell cue, not part of Galaga reference timing.
Front-door confirm frontDoor	Immediate on confirm / activation.	`uiConfirm` Implemented	Start: Initiated by shell confirm actions such as opening panels or starting a selection. Stop: One-shot cue. No explicit stop rule.	Application-owned shell cue.
Coin inserted / credit accepted frontDoor	Should occur before game start when a credit or start-ready action is accepted.	`Missing runtime slot; reference available: galaga3-coin-inserted.m4a` Missing slot, reference exists	Start: Not currently modeled in Aurora. Would likely belong at the shell-to-start boundary if we add a credit/start-ready state. Stop: Would be a one-shot cue with no stop rule.	Missing event slot. Reference clip exists and is a good future fidelity target.	No preview wired yet
Wait-mode score rotation enter wait	On entering wait mode from the shell or after attract/demo reset.	`attractEnter` Implemented	Start: Initiated when Aurora enters the score-focused wait surface. Stop: One-shot cue. Replaced naturally by later pulses.	Aurora-owned shell/wait identity cue.
Wait-mode pulse wait	Every 2.6s while wait-mode score rotation is active.	`attractPulse` Implemented	Start: Initiated by the wait-mode pulse timer to keep the surface alive without entering gameplay cadence. Stop: No explicit stop; naturally suppressed when phase changes out of wait mode.	Ambient shell pulse, not intended to match Galaga gameplay timing.
Demo entry demo	At the handoff from wait/front door into autoplay demo.	`attractEnter` Implemented	Start: Initiated once the attract loop leaves score rotation and starts demo play. Stop: One-shot cue. Followed by demo pulse cadence.	Bridge from Aurora shell into board motion.
Demo pulse / convoy ambience demo	Every 2.15s while demo is active.	`attractPulse -> galaga3-ambience-convoy.m4a (demo)` Implemented	Start: Initiated by the attract demo pulse timer. Stop: Ends when demo ends or a different phase takes over.	In Galaga reference mode this uses the convoy ambience clip rather than a shell pulse.
Game start / start preamble stage	In Galaga Reference Audio mode, gameStart now begins immediately on start input and preserves the full 4.0s reference phrase. The opening board cadence stays held until the later formation-arrival signal and first enemy entry window.	`gameStart -> galaga2-game-start.m4a full phrase` Implemented with measured full-phrase policy	Start: Initiated immediately after pressing Start for the measured stage-1 opening flow in Galaga reference mode. Stop: Stops attractEnter, attractPulse, and stagePulse before playing. One-shot cue.	Measured-reference policy: preserve the canonical 4.0s phrase first, then place the arrival signal and first visible enemies after it.
Formation arrival / stage-ready signal stage	In Galaga Reference Audio mode on stage 1, it lands about 4.18s after start input, after the full game-start phrase and before the first visible enemy arrivals around 5.35s.	`formationArrival -> galaga3-level-underscore.m4a excerpt 0.00s-0.82s` Implemented with excerpt policy	Start: Initiated by a dedicated formation-arrival timer during the stage 1 opening handoff. Stop: Stops stagePulse before playback. One-shot cue.	This is the interstitial 'they are coming' beat between the preserved opening phrase and the first visible arrivals.
Formation pulse / convoy cadence stage	Gameplay requests a pulse roughly every 0.38s, but Galaga reference mode throttles actual clip playback to about every 1.25s and suppresses it during hold windows. In the measured stage-1 opening it stays held until after the first-arrival window, around 6.15s from start input, and later stage entries now use widened reference timing windows before cadence resumes.	`stagePulse -> galaga3-ambience-convoy.m4a excerpt 0.18s-1.00s` Implemented with hold policy	Start: Initiated by the ongoing gameplay cadence loop once the stage is active and no transition/result hold is in force. Stop: Stopped or held during stage transitions, challenge transitions, and challenge result windows.	This still needs continued timing review against visible movement, but the opening window is now driven by measured reference timing rather than a convenience-shortened handoff.
Enemy dive / falling alien charge stage	In Galaga Reference Audio mode, the cue is intentionally delayed about 0.12s after dive start and after visible downward travel begins, instead of firing on the exact trigger frame.	`attackCharge -> galaga3-attack-charger.m4a` Implemented, timing under review	Start: Initiated from enemy dive start, including scripted and random dives. Stop: One-shot cue. No explicit stop rule.	Current known issue area: timing against visible dive movement still needs tuning.
Player shot stage	Immediate on player fire.	`playerShot -> galaga3-boss-damage-flagship-fighter-shot.m4a` Implemented, mapping likely too broad	Start: Initiated by the player firing a shot. Stop: One-shot cue. Cooldown-limited.	Fidelity gap: Galaga reference mode currently shares this clip with enemyShot and bossHit, so the event identity is too collapsed.
Enemy shot stage	When an enemy projectile is fired, not when a dive starts.	`enemyShot -> galaga3-boss-damage-flagship-fighter-shot.m4a` Implemented, mapping likely too broad	Start: Initiated from enemy bullet fire during formation or dive attacks. Stop: One-shot cue. Cooldown-limited.	Likely too broad: it currently reuses the same reference clip as playerShot and bossHit.
Enemy hit / enemy destroyed stage	Immediate on successful hit / kill confirmation.	`enemyHit + enemyBoom -> galaga3-zako.m4a` Implemented, hierarchy needs refinement	Start: Initiated on enemy damage or kill resolution. Stop: One-shot cues. Cooldown-limited.	Reference mode currently uses the same Zako clip for both hit and boom, so destruction hierarchy is still compressed.
Boss hit / boss destroyed stage	Immediate on boss damage or kill.	`bossHit -> galaga3-boss-damage-flagship-fighter-shot.m4a; bossBoom -> galaga3-boss-death-sasori.m4a` Implemented, visual emphasis improved and mapping still under review	Start: Initiated on boss damage and boss destruction events. Stop: One-shot cues. Cooldown-limited.	Boss death has a dedicated clip. Boss first-hit now also gets a dedicated visual flash/emphasis pass, but bossHit still shares the mixed damage/shot clip and may need a cleaner mapping.
Capture beam deploy stage	When the boss enters beam state during a capture attempt.	`captureBeam -> galaga3-tractor-beam.m4a` Implemented	Start: Initiated when a capture boss reaches the beam phase and begins the beam attack. Stop: One-shot cue with cooldown. Beam state itself ends separately.	Good direct reference mapping.
Fighter captured stage	At the exact moment the player fighter is fully captured.	`captureSuccess -> galaga3-fighter-captured.m4a` Implemented	Start: Initiated when the capture sequence completes successfully. Stop: One-shot cue with cooldown.	Important trust/fidelity event and now a dedicated Aurora-owned slot.
Capture retreat / boss exits with fighter stage	Immediately after a successful capture as the boss retreats with the fighter.	`captureRetreat -> galaga3-capturing.m4a` Implemented, mapping under review	Start: Initiated after capture success when the boss leaves with the captured ship. Stop: One-shot cue with cooldown.	Mapping is plausible but still semantically fuzzy; may need a better dedicated reference choice.
Captured fighter destroyed for points stage	Immediate when the carried fighter is destroyed.	`capturedFighterDestroyed -> galaga3-captured-fighter-destroyed.m4a` Implemented	Start: Initiated when the carried fighter itself is hit and destroyed. Stop: One-shot cue with cooldown.	Dedicated slot and direct reference mapping.
Rescue join / dual fighter rejoin stage	When the released fighter docks back and the dual-fighter state is established.	`rescueJoin -> galaga2-fighter-rescued-double-ship.m4a excerpt 2.399s-2.579s` Implemented	Start: Initiated at the rescue-join completion beat. Stop: One-shot cue with cooldown.	Dedicated slot and measured reference-window keeper promoted after full-theme precheck.
Bonus ship award stage	Immediate when the extend threshold is crossed.	`extendAward -> galaga3-extra-fighter.m4a` Implemented	Start: Initiated from score-threshold logic when an extra ship is awarded. Stop: One-shot cue with cooldown.	Direct reference mapping.
Ship destroyed stage	Immediate on ship loss.	`playerHit -> galaga3-death.m4a` Implemented, sync under review	Start: Initiated directly from the ship-loss event before respawn or game-over flow continues. Stop: One-shot cue with cooldown.	Audio fires on the loss event, but visual/audio sync still needs review.
Normal stage-to-stage transition stage	Queued late in the inter-stage window. The runtime cue now preserves a 3.35s reference-backed phrase when the handoff budget allows, so the inter-level moment no longer collapses into a short flag blip.	`stageTransition -> galaga-level-flag-v1.m4a excerpt 0.00s-3.35s` Implemented with timing-budget policy	Start: Initiated during the inter-stage handoff once the board has cleared and the transition timer reaches its cue point. Stop: Stops stagePulse, challengeResults, and challengePerfect before playback.	Now cue-budgeted and backed by reference timing windows, with later-stage entry delays used to keep arrival/cadence from stepping on the handoff.
Challenge-stage entry challenge	Queued late in the normal-to-challenge window. The challenge-entry window is now 3.35s; the cue starts about 1.13s before challenge spawn, uses a 1.6s excerpt, and preserves about 0.47s of cue tail past spawn in reference mode.	`challengeTransition -> galaga2-challenging-stage.m4a excerpt 0.00s-1.60s` Implemented with reference timing window	Start: Initiated when the next stage is a challenge stage and the transition timer reaches the challenge cue point. Stop: Stops stagePulse, stageTransition, challengeResults, and challengePerfect before playback.	Still one of the most sensitive timing/problem areas in live play, but it is now managed by a named reference timing window instead of a single hardcoded delay.
Challenge results challenge	Queued about 0.34s after challenge clear; the post-challenge result hold is now 4.25s and the next-stage handoff window is 7.35s, giving the full 4.0s reference phrase room to finish before the next-stage cue.	`challengeResults -> galaga2-challenging-stage-results.m4a excerpt 0.00s-4.00s` Implemented with widened handoff policy	Start: Initiated when a challenge stage is cleared without a perfect result. Stop: Stops stagePulse, stageTransition, and challengeTransition before playback; also holds ambient cadence.	Now separated from challengePerfect and given a wider hold window so the result phrase can finish before the next-stage handoff.
Challenge perfect result challenge	Queued about 0.34s after a perfect challenge clear; excerpt runs the full 4.0s reference phrase with the same widened result hold and next-stage handoff window as challenge results.	`challengePerfect -> galaga2-challenging-stage-perfect.m4a excerpt 0.00s-4.00s` Implemented with hold policy	Start: Initiated when a challenge stage is cleared perfectly. Stop: Stops stagePulse, stageTransition, and challengeTransition before playback; also holds ambient cadence.	Direct reference mapping with runtime-safe duration.
Game over results	On terminal ship loss when the game-over state is entered.	`gameOver -> galaga-last-ship-destroyed-ambience.m4a` Implemented	Start: Initiated from the gameOver transition after the final ship is lost. Stop: One-shot cue with cooldown.	Uses the long ambience reference; may later need a dedicated runtime-safe excerpt if it collides with results flow.
High score name entry (1st place) results	When game-over/results enters a 1st-place name-entry flow.	`highScoreFirst -> galaga3-name-entry-1st.m4a` Implemented	Start: Initiated when the results rank is exactly first place. Stop: One-shot cue with cooldown.	Dedicated slot.
High score name entry (2nd-10th) results	When game-over/results enters a non-first high-score entry flow.	`highScoreOther -> galaga3-name-entry-2nd-5th.m4a` Implemented	Start: Initiated when the results rank is a non-first leaderboard placement. Stop: One-shot cue with cooldown.	Currently uses the 2nd-5th reference clip for the broader non-first ranking bucket.
Enemy-family-specific attack / death timbres stage	Would occur on specific enemy-family attack or kill moments.	`Reference clips exist: galaga3-goei-midori-tonbo-momiji-enterprise.m4a, galaga3-transformation.m4a, galaga3-zako.m4a` Missing finer-grained slots, reference exists	Start: Not currently modeled as distinct Aurora cue slots; Aurora collapses these into generic attackCharge, enemyHit, enemyBoom, and bossHit cues. Stop: N/A	Likely future fidelity feature rather than a current bug, but it explains why some combat events still feel flattened compared to Galaga.	No preview wired yet

Theme Comparison

Compare the same gameplay moments side by side. Aurora uses the application-owned mix, Galaga uses the current synthetic classic-leaning runtime family for the same cue and phase, and Reference plays the actual extracted Galaga clip we currently treat as the best mapping target.

Gameplay Element	What To Compare	Review Actions
Demo Pulse	Compare autoplay cadence and whether the board feels mechanically alive enough once demo motion begins. Mapping status: Synthetic Galaga runtime cue vs actual indexed reference clip. Confidence: high	Ambience / Convoy
Stage Start	Compare whether stage start feels like a clear arcade start/announcement instead of a generic cue. Mapping status: Best current stage-start mapping from the cue matrix. Confidence: medium	Start
Formation Pulse	Compare ongoing formation cadence and whether gameplay feels like it has enough marching pressure. Mapping status: Strongest current reference for the board cadence bed. Confidence: high	Ambience / Convoy
Player Shot	Compare whether player fire reads as a quick arcade shot instead of a generic impact. Mapping status: Measured subwindow promoted for shot identity; uses a distinct initial transient so player fire can be scored separately from enemy fire and boss damage. Confidence: medium-high	Flagship/Fighter Shot
Enemy Shot	Compare whether enemy fire is distinct enough from player fire and boss damage. Mapping status: Measured subwindow promoted for enemy projectile feedback; still from the same source clip, but scored as a distinct reference phrase from playerShot and bossHit. Confidence: medium-high	Flagship/Fighter Shot
Enemy Hit	Compare whether an enemy impact gives immediate hit confirmation. Mapping status: Measured subwindow promoted for impact feedback; hit and kill hierarchy remains under review but is now scored against a distinct phrase from enemyBoom. Confidence: medium-high	Zako
Boss Hit	Compare whether boss damage reads as a distinct multi-hit event. Mapping status: Measured subwindow promoted for boss damage feedback; reference source remains shared, but bossHit now has a dedicated scoring window. Confidence: medium-high	Boss Damage / Flagship Fighter Shot
Enemy Boom	Compare whether normal enemy destruction is more emphatic than a simple hit. Mapping status: Measured subwindow promoted for normal-enemy destruction feedback; enemyHit and enemyBoom now score against separate Zako phrases. Confidence: medium-high	Zako
Boss Boom	Compare whether boss destruction feels larger and more final than normal enemy destruction. Mapping status: Measured coverage added for boss destruction feedback. Confidence: high	Boss Death / Sasori
Capture Beam	Compare whether the beam deploy moment reads clearly as tractor-beam danger. Mapping status: Strong direct mapping. Confidence: high	Tractor Beam
Capture Retreat	Compare whether the post-capture retreat phase remains audible as a distinct state. Mapping status: Measured coverage added for the transition between beam danger and captured-fighter state. Confidence: medium	Capturing
Fighter Captured	Compare the exact moment the fighter is fully captured, distinct from beam deploy and retreat. Mapping status: New Aurora cue slot added from the cue matrix. Confidence: high	Fighter Captured
Captured Fighter Destroyed	Compare the regret/penalty moment when the carried fighter is destroyed. Mapping status: New Aurora cue slot added from the cue matrix. Confidence: high	Captured Fighter Destroyed
Rescue Join	Compare whether the rescue/join moment feels celebratory and distinct from ordinary scoring. Mapping status: Strong direct mapping. Confidence: high	Fighter Rescued (Double Ship)
Ship Loss	Compare whether ship loss feels like a real Galaga death moment rather than a generic impact. Mapping status: Strong direct mapping. Confidence: high	Death
Challenge Transition	Compare how distinct and ceremonial the challenge-stage announcement feels. Mapping status: Strong direct mapping. Confidence: high	Challenging Stage
Challenge Results	Compare whether challenge wrap-up feels like a proper result phrase instead of a generic transition. Mapping status: New Aurora cue slot added from the cue matrix. Confidence: high	Challenging Stage Results
Challenge Perfect	Compare whether a perfect challenge result feels more celebratory than the standard results cue. Mapping status: New Aurora cue slot added from the cue matrix. Confidence: high	Challenging Stage Perfect
High Score 1st	Compare whether first place entry feels distinct and more important than a lower board placement. Mapping status: New Aurora cue slot added from the cue matrix. Confidence: high	Name Entry (1st)
High Score 2nd-10th	Compare whether non-first leaderboard entry feels positive but smaller than first place. Mapping status: New Aurora cue slot added from the cue matrix. Confidence: high	Name Entry (2nd-5th)
Game Over	Compare whether the ending cue feels final and emotionally complete enough. Mapping status: Best current end-state reference; still broader than Aurora's single slot. Confidence: medium	Last Ship Destroyed Ambience

Stage Family Progression

How Aurora changes the visible enemy families and named boss archetypes as stage bands advance.

Stage Band	Families In Use	Boss Archetype	Description
quiet-skies from stage 1	bee classic · but classic · boss classic · challenge classic	`command-core`	Classic opening Aurora band. Closest to original Galaga feel in stars, enemy look, and cadence.
scorpion-dawn from stage 4	bee scorpion · but scorpion · boss classic · challenge classic	`super-boss-scorpion`	First Aurora-flavored band. Adds scorpion family visuals while keeping the challenge family conservative.
stingray-surge from stage 8	bee stingray · but stingray · boss stingray · challenge dragonfly	`partner-wing-stingray`	Main later-stage Aurora band where both background and audio identity shift clearly away from the classic opening.
galboss-veil from stage 12	bee galboss · but galboss · boss galboss · challenge dragonfly	`council-boss`	Heavier late-stage band with the galboss family and stronger aurora presentation.
crown-aurora from stage 16	bee galboss · but galboss · boss galboss · challenge mosquito	`super-partner-pair`	Late Aurora crown band tying the strongest shell/front-door identity back into the deeper stage family.

Artifact Conformance Status

Target-versus-current conformance across the application artifacts that shape the game: sprite targets, sprite motion, audio cues, backgrounds, shell/icon surfaces, fonts, stage feel, and boss choreography. Rows are generated from the current analysis artifacts so the scorecard stays tied to measured evidence.

Artifact Surface	Current / Target	Measurement	Evidence	Next Gap
Sprites: docs catalog proxy vs inferred Galaga pixel models Measured proxy; keep alongside live runtime canvas score	6.2/10 Target: >=8.5/10 as a fast docs/current-definition proxy	8 catalog keys compared; model confidence 94% from 21 accepted source samples; weakest current proxy challenge-dragonfly 5.5/10.	`reference-artifacts/analyses/galaga-reference-sprites/model-0.1.json` `reference-artifacts/analyses/galaga-reference-sprites/pixel-targets-0.1.json`	Use this as the cheap warning metric when docs/current definitions drift from the target model; the runtime canvas metric is the player-visible read.
Sprites: live runtime canvas capture vs inferred Galaga pixel models Measured from isolated live canvas crops	6.2/10 Target: >=8.5/10 against isolated live-rendered canvas captures	8 live sprite captures; weakest runtime sprite boss-line 5/10; capture mode isolated-live-canvas-sprite-crops.	`reference-artifacts/analyses/aurora-runtime-sprite-conformance/latest.json`	Expand from static isolated poses into animation-phase, dive-rotation, formation-context, and capture/rescue runtime sprite windows.
Sprites: live runtime crops vs promoted Galaga target crops first-pass-normalized-image-grid-comparison	6/10 Target: >=8.5/10 against promoted multi-pose target crop library	8 live runtime crop PNGs compared against 33 promoted target crops; weakest challenge-mosquito 3.7/10; best matched target challenge-yellow-family-front. Target-relative cadence sequence score 5.7/10 across 3 sequence window(s).	`reference-artifacts/analyses/aurora-runtime-vs-galaga-target-crops/latest.json`	Use the top candidate mismatch and target-sequence data to update sprite geometry, flap cadence, target mappings, and composite targets; then expand to dive, capture/rescue, projectile, explosion, tractor beam, and challenge-stage specialty motion.
Sprite motion: flapping, pulsing, dive poses, and transition animation Measured correspondence; frame-labeled-segmented-reference-windows	6.2/10 Target: >=8.0/10 temporal correspondence against frame-labeled target cadence windows	Correspondence score 6.2/10 across 3 Boss/Bee/Butterfly rows; weakest bee-zako-pulse-pair 5.4/10; frame-labeled segmented-reference rows 3; provisional target rows 2.	`reference-artifacts/analyses/aurora-sprite-motion-correspondence/latest.json` `reference-artifacts/analyses/aurora-runtime-sprite-conformance/latest.json`	Confirm segmented-reference cadence against raw gameplay or ROM-derived timing, then tune Aurora runtime cadence and challenge-stage alien motion against the accepted target rows.
Impact and explosion visual feedback static-runtime-effect-crop-plus-lifecycle-and-audio-coupling	5.9/10 Target: >=7.5/10 static event crop score plus temporal lifecycle scoring	4 runtime impact/explosion crops compared against promoted target explosion crops; weakest boss-first-hit 5.6/10; lifecycle 4/10; audio coupling 8.1/10. Impact/explosion visual feedback is measurable but still immature. Weakest static event is boss-first-hit at 5.6/10; weakest lifecycle event is boss-first-hit at 3.7/10. The scorer now checks onset/expansion/decay and expected audio cue presence.	`reference-artifacts/analyses/aurora-impact-explosion-conformance/latest.json`	Replace first-pass lifecycle heuristics with exact frame-labeled Galaga gameplay timing, then use visual/audio coupling to decide whether boss first-hit, normal kill, and boss death read distinctly enough to players.
Reference sprite targets: source-frame pixel library Source-frame pixel targets promoted	8 catalog keys covered by 6 exact crops Target: All live ship/enemy catalog keys covered by source-frame targets	6 unscaled PNG crops cover bee-line, boss-line, but-line, challenge-dragonfly, challenge-mosquito, dual-fighter, player-fighter, rogue-fighter; target dimensions are verified against crop metadata.	`reference-artifacts/analyses/galaga-reference-sprites/pixel-targets-0.1.json`	Add additional formation, animation-phase, and damage-state crops so target references cover more than the static catalog poses.
Reference sprite targets: promoted sheet pose crops First-pass source-sheet target library; trusted-core-formation-targets-ready-runtime-comparison-pending	33 promoted crops across 7 role sets Target: Multi-pose target sets for player, bee, butterfly, boss, challenge aliens, projectiles, explosions, and tractor beam	33 exact 1x source-sheet crops; roles bee-zako, boss-galaga, butterfly-escort, challenge-specialty-aliens, player-fighter, projectiles-and-impacts, tractor-beam; source-pixel exact pending.	`reference-artifacts/analyses/galaga-alien-target-crops/latest.json`	Replace challenge-only specialty alien provisional cells with clean target motion/gameplay windows, then regenerate Aurora live runtime comparisons with authority-adjusted scoring.
Audio cues: runtime cue assets vs Galaga-family references Primary user-experience gap	7.3/10 Target: >=7.5	21 cue/event comparisons, 31 segment-role comparisons, semantic score 9.8/10, highest risk challengePerfect 7/10.	`reference-artifacts/analyses/aurora-audio-conformance-lab-v2/latest.json` `reference-artifacts/analyses/aurora-audio-event-gap/latest.json` `reference-artifacts/analyses/quality-conformance/2026-05-24-ff249bba/report.json`	Tune the highest segment-level gap next: challengePerfect onset. Rerun audio comparison and event-gap analysis after the change.
Audio timing and event alignment Guardrail measured in quality conformance	9/9 checks passed Target: All event-alignment checks pass with low drift	Worst current delta 6.31 ms; worst drift from baseline 0 ms.	`reference-artifacts/analyses/quality-conformance/2026-05-24-ff249bba/report.json`	Keep event alignment coupled to the cue-contract promotion pass so timing does not regress while changing source clips.
Backgrounds, starfield, and arcade atmosphere New explicit gate; first-pass scorer measured	8.6/10 Target: >=8.4	4 browser surfaces measured; evidence coverage 1; frame containment average 1; weakest surface Developer/settings popup surface 7.1/10.	`reference-artifacts/analyses/aurora-visual-look-conformance/latest.json`	Add direct Galaga contact-sheet targets for background density, starfield cadence, palette spread, and attract/gameplay contrast.
Frame, popups, shell controls, and icons Split from generic UI shell before final gate	9.2/10 Target: >=9.4	12 surface guardrails in latest quality report; visual scorer weakest shell surface Developer/settings popup surface 7.1/10.	`reference-artifacts/analyses/release-conformance-dashboard/latest.json` `reference-artifacts/analyses/quality-conformance/2026-05-24-ff249bba/report.json` `reference-artifacts/analyses/aurora-visual-look-conformance/latest.json`	Split iconography, dock-button affordance, and popup typography into separate target rows once we have icon/font-specific captures.
Fonts, typography, and text containment Measured as layout/text containment, not yet arcade font identity	7.1/10 Target: >=8.4/10 visual gate; font-authenticity target still pending	4 overflow markers across 4 surfaces; weakest text-heavy surface Developer/settings popup surface at 7.1/10.	`reference-artifacts/analyses/aurora-visual-look-conformance/latest.json`	Add pixel-font targets for score labels, score-table labels, popup headings, and HUD numerals so font authenticity gets its own score.
Stage backgrounds, level arc, and encounter shape Long-play gameplay-quality gate	8.8/10 Target: >=8.8	Release gate tracks stage distinctiveness, challenge identity, pressure curve, reward/rescue layering, and learning/mastery windows.	`reference-artifacts/analyses/release-conformance-dashboard/latest.json`	Tie visual background/theme transitions to the level-arc windows so stage identity scores include both motion and look.
Bosses, formation grammar, and alien entry choreography New measured gate for stage choreography	9.4/10 Target: >=8.0 first gate; >=9.0 mature	Companion novelty gate 8.2/10 for broader alien entry/challenge variety.	`reference-artifacts/analyses/release-conformance-dashboard/latest.json`	Continue frame-labeled path references so boss and alien choreography can be judged against exact source trajectories.

Target Artifact Coverage

The online and local Galaga artifacts that best illustrate Aurora's target, with explicit status for what has actually been ingested. This keeps challenge-stage, sprite, audio, rules, and screen-surface work tied to visible evidence instead of loose memory.

Coverage read: 5.1/10 overall target-artifact ingestion; 4.5/10 challenge-stage target readiness; 0 late challenge windows still missing.

Aurora now has media-backed windows for all tracked Galaga challenge stages, including Challenges 4-8. The bottleneck has moved from source acquisition to precision: each window needs five-group frame labels for entry side, path family, scoreable band, exit side, alien family, and perfect-bonus opportunity before direct trajectory scoring should rise.

Alien Motion Reference

Segmented Galaga alien video reference for pulse cadence, role taxonomy, and clean human-readable sprite identity. This sits between static crop extraction and gameplay trajectory scoring: it helps us see whether the sprite identities move and pulse like the target before we promote a conformance claim.

Current read: ingested-reference-motion-taxonomy. User-supplied Galaga alien motion/pulse video ingested as a durable sprite-motion reference for taxonomy, pulse cadence, and clean role-silhouette review.

Conformance use: This artifact is stronger for human-readable taxonomy, pulse cadence, and clean silhouette targets than the currently polluted crop boxes in some rows. It should not replace source-sheet exact crops alone; it should validate and correct target crops, then seed temporal pulse/cadence scoring.

Trusted Target Evidence Audit

Human review found that some visually precise target crops were precise about the wrong thing: polluted sheet cells, partial neighboring sprites, or ambiguous evidence. This audit separates trusted target evidence from provisional planning evidence before scores drive more runtime sprite work.

Current read: trusted-target-manifest-active. Next best step: Promote clean challenge-specialty target windows before treating late challenge alien graphics as release-facing conformance truth.

Alien Temporal Targets

Temporal sprite identity is now treated separately from static sprite identity. These rows define the pose sequences the runtime cadence scorer uses for Boss, Bee, and Butterfly, while clearly marking which parts are trusted motion-reference evidence and which parts are still provisional.

Current read: mixed-confidence-temporal-target-sequences. Next best step: Confirm segmented-reference cadence against raw gameplay or ROM-derived timing, then extend the method to dive/rotation and challenge-only aliens.

Sprite Motion Correspondence

This is the bridge between Galaga temporal target evidence and Aurora runtime motion captures. It answers whether current sprites merely look acceptable in still crops or actually move with enough flap, pulse, cadence, dive, and transition evidence to support challenge-stage conformance claims.

Current read: 6.2/10. Timing status: frame-labeled-segmented-reference-windows. Next best step: Confirm segmented-reference cadence against raw gameplay or ROM-derived timing, then tune Aurora runtime cadence and challenge-stage alien motion against the accepted target rows.

Sprite Conformance Plan

Build one repeatable sprite pipeline that can reach high measured reference conformance, then branch into production-safe Aurora and future-game visual themes without losing the era, motion, and gameplay readability characteristics of the source.

Plan status: active-plan. Next best step: Promote a clean player-fighter target-crop, add temporal pulse-pair targets for Boss/Bee/Butterfly, then tune Aurora runtime-vs-target sprite geometry against the corrected target library before the next beta handoff.

This plan separates the internal reference-conformance lane from the Aurora production theme lane. The goal is to ingest and measure toward a conforming experience, then let Aurora and later Platinum games ship distinctive original visual styles that preserve era, motion, role readability, and gameplay meaning.

Promoted Galaga Target Crops

The target crop library now combines trusted cleaned motion-reference crops for the core Boss, Bee, and Butterfly formation targets with provisional source-sheet pose crops for broader planning coverage. These crops are target-lane evidence for measurement and review; they are not public production art. Aurora live runtime sprites are compared against this multi-pose library, and the next lift is deeper temporal windows for flap cadence, dive rotation, beam, explosion, capture, and challenge-stage motion.

Aurora Runtime Versus Target Crops

This is the stricter live-rendered sprite read: each Aurora canvas crop is compared against accepted Galaga target crops after semantic role filtering. Low values here are not failures of the plan; they are the exact gaps the next sprite passes should attack.

Impact And Explosion Feedback

The first impact/explosion comparator captures event visuals from the current runtime and compares them against promoted Galaga target explosion crops. This is the start of making missile impacts, boss damage, kills, and death rewards measurable instead of relying on subjective review.

Current read: 5.8/10 average static event score; 4.0/10 lifecycle score; weakest boss-first-hit 5.6/10.

Source artifact: reference-artifacts/analyses/aurora-impact-explosion-conformance/latest.json. The scorer now captures onset/expansion/decay and expected audio cue coupling, but still needs exact target-video frame labels.

Lane	Purpose	Renderer Expectation	Metrics	Use
Reference Conformance Lane `reference-conformance-lane` developer/internal measurement first	Show and measure the closest legally appropriate Galaga-like game experience so the team can assess what conformance would look like before creative variation.	Fixed low-resolution gameplay buffer, integer or controlled scaling, no smoothing, target-crop sprite atlases or target-derived pixel-row manifests, authored pose frames instead of arbitrary canvas rotation.	`static target crop similarity` `pose-set coverage` `flap and pulse cadence` `dive/rotation silhouette sequence similarity` `capture/rescue transition readability` `projectile/explosion vocabulary alignment` `formation and challenge-stage context fit`	Use for internal target comparison and measurement.
Aurora Production Theme Lane `aurora-production-theme-lane` public Aurora production	Ship original Aurora art that feels era-faithful and arcade-readable while avoiding a direct copy of target art.	Uses the same sprite-role/pose manifest shape as the conformance lane, but with Aurora-owned pixel art, palettes, effects, and themed variations.	`role readability` `silhouette family similarity band` `palette-era fit` `motion cadence fit` `player comprehension during hits, captures, rescues, and challenge stages` `theme distinctiveness`	Use for public Aurora originality and era-faithful presentation.
Future Game Ingestion Lane `future-game-ingestion-lane` new game onboarding	Use the same source-to-target-to-variation loop for Galaxy Guardians and later games so new games begin with measured artifacts, not hand-waved design memory.	Game-owned target packs and themed packs share the same manifest schema, crop review, scorer, and developer toggle vocabulary.	`source coverage` `target extraction confidence` `role/pose manifest completeness` `runtime-vs-target conformance` `theme variation distance` `compute cost per conformance lift`	Use to onboard future games through the same artifact loop.

Pipeline Step	Goal	Current Status	Next Action
1. Source Manifest `source-manifest`	Register lawful target sources and classify them as scoring targets, human-review context, secondary validation, or planning-only references.	Galaga alien close-ups are ingested and classified; general sprite sheet is the strongest current static target candidate; a segmented alien motion/pulse video is now registered as a target-validation and temporal-reference source.	Keep source authority explicit when new sprite sheets, gameplay clips, posters, or manual screenshots enter the project.
2. Crop-Box Manifest `crop-box-manifest`	Define bounding boxes for player, bee, butterfly, boss, captured fighter, projectiles, tractor beam, explosions, challenge aliens, and each important pose frame.	First-pass region manifest exists at reference-artifacts/ingestion/galaga-alien-visual-reference/crop-box-manifest-0.1.json, generated review previews exist at reference-artifacts/analyses/galaga-alien-visual-crop-previews/latest.json, and per-role/per-pose target crops now exist at reference-artifacts/analyses/galaga-alien-target-crops/latest.json. Human review found polluted crop evidence for the original boss/bee/butterfly target rows, so the library now separates trusted cleaned motion-reference crops from provisional source-sheet cells and records that decision in reference-artifacts/analyses/galaga-target-evidence-audit/latest.json.	Regenerate runtime-vs-target scoring against the trusted boss, bee, and butterfly crops, then promote clean player-fighter and temporal pulse-pair targets before making additional runtime sprite changes.
3. Pose And Motion Targets `pose-and-motion-targets`	Group static crops into temporal identities: flap cycles, dive turns, boss damage, capture/rescue, dual fighter, projectiles, and explosions.	Static model and runtime crop scoring exist, and a 33-crop/7-role promoted target library now supplies multi-pose static targets. Primary Boss/Bee/Butterfly/Fighter crops are trusted cleaned motion-reference targets; remaining source-sheet cells are provisional until recropped or replaced by temporal windows. Seed runtime windows now cover all four planned motion axes: flap phase pairs, full flap cadence, dive/rotation poses, capture/carry/dual transitions, and first-pass impact/explosion event crops. A segmented alien motion/pulse video now provides cleaner human-readable pulse/cadence evidence for Boss, Butterfly, Bee, specialty aliens, Fighter, and Tractor Beam. Temporal target rows now exist at reference-artifacts/analyses/galaga-alien-temporal-targets/latest.json, with Boss stronger than Bee/Butterfly because the latter still depend on provisional flap cells.	Replace provisional Bee and Butterfly flap cells with clean frame-timed target windows, then score Aurora runtime cadence against those target sequences.
4. Runtime Renderer Path `runtime-renderer-path`	Render sprites through a fixed-buffer, smoothing-free, artifact-driven path that supports target mode and creative theme variants.	Current canvas path is DPR-aware and smoothing-free, but sprites are still compact hand-authored patterns and responsive scaling complicates pixel scoring.	Prototype a sprite atlas/pixel-row renderer behind a development flag before changing normal gameplay.
5. Scoring And Gates `scoring-and-gates`	Score static crops, active motion, stage context, player meaning, and shipped-theme originality separately.	Runtime static sprite score is 5.75/10 against inferred models while the stricter runtime-vs-promoted-target-crop comparator now reads 4.33/10 after replacing polluted Boss/Bee/Butterfly targets with trusted motion-reference crops. That score decrease is useful: it removes false confidence and exposes the direct visible geometry gap. Impact/explosion feedback has a first-pass static crop comparator at 5.86/10 after adding a target-derived pixel explosion layer. Active sprite motion has seed windows but is not yet target-frame temporal scoring.	Move direct target sprite score toward 5.5+ before the next beta claim, keep challenge-stage set-piece conformance above 5.0 before claiming a beta conformance lift, and add confidence/resolution plus temporal target scoring.
6. Variation Generation `variation-generation`	Use artists, scripts, model-assisted generation, or tools such as agent-sprite-forge to create era-faithful original variants after the target lane is understood.	Candidate tooling noted but not adopted; generated assets should be treated as candidates until reviewed, cropped, scored, and committed.	Evaluate candidate generation tools against the same manifest and scoring shape, not as a replacement for source-grounded targets.
7. Developer Controls `developer-controls`	Expose conforming mode, Aurora theme mode, and future-game theme variants through developer settings for visual comparison and evidence capture.	Developer graphics/audio settings exist, but no formal sprite-conformance lane toggle exists yet.	Add a future developer setting for Sprite Mode: Reference Conformance, Aurora Production, and Theme Variant once target packs exist.

Gate	Target	Meaning
Short Term `short-term`	Crop-box manifest exists for the strongest Galaga sprite sheet, and the Application Guide shows target crops beside Aurora runtime crops.	Next practical implementation target.
Medium Term `medium-term`	Runtime sprite scoring compares multiple poses per role and moves from static-only 6.2/10 toward 7.5+/10 without overstating motion coverage.	Tracked as the sprite pipeline matures.
Release Gate `release-gate`	Before the next beta conformance claim, strict direct target sprite conformance should be at least 5.5/10 and challenge-stage set-piece conformance should be at least 5.0/10. Before broad public promotion, production theme sprites are original, readable, era-faithful, and backed by conformance-lane evidence plus variation-distance notes.	Required before broad public claims.
Long Term `long-term`	The same sprite ingestion, scoring, and variation pipeline can onboard a new Platinum game with minimal bespoke authoring.	Tracked as the sprite pipeline matures.

Stage Conformance Summary

Stage-by-stage and stage-band summary of difficulty, maneuvers, trajectory identity, gameplay description, current evidence, and the main conformance gap.

Stage / Band	Gameplay Summary	Key Aspects	Evidence	Gap
Stage 1	Baseline rack entry, first dives, low pressure, player onboarding.	Formation arrival timing, first dive timing, safe early pressure, classic visual/audio framing.	stage-1-baseline evidence window; stage-1 geometry and shot trust guardrails.	Improve direct visual reference grounding for alien/player likeness.
Stage 3 / first challenge	First challenging stage and bonus-stage learning moment. Current critical read: the rule baseline is present, but the set piece does not yet read enough like Galaga's first challenge.	Non-lethal challenge behavior, no enemy shooting, no ship loss, visible arrival and peel-off patterns, bee/butterfly bonus-line grammar.	Challenge timing guardrails, challenge-stage candidate window, and reference-artifacts/analyses/challenge-stage-conformance/latest.json.	Make stage 3 best-match challenge-1 arrival/late-wave references instead of a later mixed challenge target.
Stage 4	First major pressure step and capture/squadron importance.	Boss capture, special attacks, lane pressure, player loss windows, fairness.	Stage 4 pressure geometry, lane loss windows, close-shot trust harnesses.	Continue pressure precision while protecting fairness and persona safety.
Stage 7 challenge	Scorpion cross-sweep challenge set piece. Current critical read: the label variation exists, but the measured vector still clusters too close to the same broad challenge-reference family.	No enemy shooting, no ship loss, mixed alien families, cross-sweep path family, higher-density bonus pattern.	challenge-stage-scorpion-cross, alien-entry/challenge-variation, formation-boss path extraction, and challenge-stage conformance artifacts.	Turn stage 7 into a true challenge-2 contract with group-by-group mixed-novelty scoring and visible entry/exit differences.
Stage 11 challenge	Stingray hook-arc challenge set piece. Current critical read: dragonfly family presentation is visible, but active sprite-motion novelty is not yet measured.	No enemy shooting, no ship loss, new challenge-family visual language, hook-arc motion, later-stage bonus pattern novelty.	challenge-stage-stingray-hook, path-family comparison, and challenge-stage conformance artifact.

Level Visual Conformance Index

Ordered current-versus-target visual evidence for every Aurora level and each Challenging Stage. Each row keeps the current runtime screenshot beside an actual Galaga gameplay target frame, then expands into scene roles, bitmap pairs, conformance metrics, and the next gap.

Current read: 39 ordered rows; 31 regular levels; 8 challenging stages; 39 Aurora screenshots; 39 target gameplay screenshots; 39 Aurora 10s clips; 39 target 10s clips.

Conformance pressure: 4.2/10 challenge visual conformance and 3.6/10 target grounding. The generated index now contains 39 ordered rows: 31 regular levels and 8 challenging stages. Every row has a current Aurora runtime screenshot, an actual Galaga target-gameplay frame, and paired 10-second current/target gameplay clips for inline motion review. The important caveat is grounding quality: 14/39 target rows are exact ingested windows, while 25 regular-level rows use representative actual Galaga gameplay until a full per-level normal-stage corpus is ingested. Challenge-stage visual conformance remains the most human-visible failure: exact challenge target screenshots exist, but the strict challenge score is only 4.2/10.

Target-grounding caveat: 14/39 rows currently use exact ingested target windows. 25 regular-level rows use representative actual Galaga gameplay frames until the normal-stage corpus is extended. That means the section is excellent for seeing the shape of the gap, but it is not yet a complete per-level proof of conformance.

This row is honest about target debt: it uses actual Galaga gameplay from Representative Galaga target: Stage 4 post-challenge rack entry, but not an exact per-level target capture. The useful review question is whether Aurora’s current frame has a readable rack/entry state, recognizable bee/butterfly/boss roles, and stage-band pressure rather than only a different background.

Critical gap: Exact target frame for Level 3 is missing from the ingested corpus; this should not be scored as fully grounded visual conformance.

Conformance Read

This is a no-combat bonus exhibition, so safety is only the floor. Current Aurora still reads weak on movement grammar, alien novelty, and graphical spectacle unless the strict scores here are materially higher than 6/10.

Critical gap: Alien/stage novelty is only 3.9/10: the current type mix does not yet prove Galaga-like new alien introductions, memorable challenge-specific roles, or distinct bonus-stage learning patterns.

Next: Protect the first-challenge bee/butterfly line contract, then tune path length, turn count, and rack-slot precision against challenge-1 arrival and late-wave labels.

Challenge Timing Alignment Review

Stage-start synchronized Galaga target versus Aurora current videos for challenging stages. These clips make pace drift, visible arrival timing, score-window timing, and complexity mismatches reviewable without guessing which mid-stage moment is being compared.

Current read: 4 challenging-stage row(s), 4 paired timing clips, 4 contact sheets, average absolute end drift 1.53s.

Requested challenges 1, 2, 3, 4; completed 1, 2, 3, 4; no capture failures. These videos put Galaga target footage on the left and Aurora current controlled-clock footage on the right from t=0, so pace and complexity drift can be reviewed without guessing which mid-stage moment was sampled.

This is the review layer for pacing drift, group count, visible arrival versus appearance, route complexity, and whether the score window arrives at the right relative time.

Challenge Stage Deep Dive

A deliberately critical stage-by-stage comparison of Aurora challenging stages against Galaga-style bonus-stage behavior. This separates rule conformance from interesting visual conformance: no enemy shooting and no ship loss are necessary, but the higher-value gap is authored alien movement, alien-family variation, and learnable set-piece novelty.

Current strict read: 4.3/10 interesting factor; 4.4/10 movement; 4.5/10 graphics; 3.9/10 alien novelty; 5.4/10 shot opportunity; 4.3/10 challenge-stage conformance.

current challenge stages are functionally safe but not yet fully credible Galaga-like bonus exhibitions: strict movement is 4.4/10, strict graphics is 4.5/10, alien/stage novelty is 3.9/10, player shot opportunity is 5.4/10, target-video object-track fit is 3.5/10, and sprite-motion correspondence is 6.18/10 with target timing status frame-labeled-segmented-reference-windows. Diagnostic legacy coverage was 6.8/10, which is why the old read was too generous.

Scoring model: strict-v2-user-baseline. Each challenge starts at 1/10 for interest, movement, and graphics; no-shot/no-kill safety is a required guardrail, not a score booster. Legacy broad coverage is diagnostic only.

Best candidate stage7-centerline-spacing-spread-left-right-lead078-flat-widefield-centered-id-sd018 scored 5.7/10 expected-reference and 4.2/10 target-video fit.

Deconflict underperformance: Route-aware group offsets now beat direct deconflict on bunching risk, but they remain far from the promotion gate and need density, target-fit, and human-perfect review before runtime promotion. Direct deconflict still improves baseline readability, but the rejected full-analyzer trial shows local deconfliction can create misleading wins.

Decision: no-runtime-keeper-yet. Gates: Safety remains pass: no challenge enemy shots, enemy attacks, or ship loss. Human-perfect potential must not regress from baseline and should remain >= 7.4/10. Human-visible score should improve materially and remain >= 7.8/10 before promotion. Bunching risk should move toward <= 0.36; interim candidates below 0.65 are worth full-analyzer review.. Next: Use route-aware group offsets to separate whole groups before adding object-level offsets. Prefer contract-shaped candidates over broad blind sweeps. Generate path visuals for baseline, best readability, best route-aware, and best deconflict candidates. Promote only after full analyzer confirms the expected-label and target-video lift..

Naming rule: normal Levels and Challenging Stages are separate. The challenge rows below preserve internal stage markers for traceability; human-facing copy should use between-stage labels like Challenging Stage A-B once the runtime mapping is confirmed.

Evidence-image rule: contact sheets are supporting artifacts for visual inspection, not the main human-readable conformance explanation. Use each row's target/current/conformance text for the judgment; open the evidence panel only when you need to inspect the underlying frames at native scale.

Stage 7 Before/After Evidence

Stage 7 now preserves reference-path metadata across 5 target tracks and 80% of sampled challenge enemies, compared with 0% in the pre-promotion control. Use the contact sheet to review whether that metadata lift is visible as better authored motion; do not treat it as a solved challenge-stage conformance score.

Before reference-path coverage: 0%
After reference-path coverage: 80%
After target tracks: target-track-10, target-track-110, target-track-142, target-track-66, target-track-71

Player-Facing Read

The visible aim is a safer, more learnable bonus-stage route: enemies should feel like authored groups sweeping in, not appearing or bunching unpredictably.

Artifact: reference-artifacts/analyses/stage7-reference-path-before-after/latest.json

Process Read

This artifact keeps the before/after proof close to the metric so future challenge promotions must show visible evidence, not only numerical candidate fit.

Next: use this pattern before promoting another challenge-stage runtime change.

Peek at the living effort summary

A player should experience challenging stages as safe but tense score exhibitions with memorable entry routes, fresh alien types, readable trajectories, and a learnable perfect-bonus opportunity. Aurora currently preserves the safety rule, but the actual spectacle, motion, and visual novelty are still early.

Open full effort summary

Peek at related report and measurements

Design work should move from broad path-family labels to explicit per-challenge contracts: group order, first-visible frame, entry side, exit side, path length, turn count, alien family, animation phases, bonus opportunity, and result feedback.

Improvement plan:

Use strict challenge-stage scores as the release-facing truth; keep broad coverage scores only as diagnostics.
Define a challenge-stage target grammar for group order, entry/exit side, path length, turn count, featured alien, scoring window, perfect bonus, animation phases, and result feedback.
Stage 3: rebuild Challenging Stage 1 against the Galaga challenge-1 arrival and late-wave references with visibly longer movement and readable exits.
Stage 7: rebuild Challenging Stage 2 as a separate mixed-novelty crossing set piece with different entry/exit and timing grammar.
Stage 11: rebuild Challenging Stage 3 around boss-led novelty plus active sprite-motion scoring.
Stage 15/19/23/27/31: continue replacing repeated late-stage patterns with first-pass media-backed contracts, then promote each to five-group frame labels.
Publish contact sheets, trajectory SVGs, per-stage critical gaps, and strict axis scores in generated docs.

Sprite-motion correspondence is 6.18/10: runtime flapping/cadence is visible, but target frame timing is still frame-labeled-segmented-reference-windows and weakest motion row is bee-zako-pulse-pair.
Alien/stage novelty is only 3.9/10: the current type mix does not yet prove Galaga-like new alien introductions, memorable challenge-specific roles, or distinct bonus-stage learning patterns.
Target-contract fit is only 4.4/10: the runtime group order, path families, type/family mix, or group count still misses the first-pass media-backed challenge contract.
Pink-serpentine identity now lands on its first-pass late reference, but it still needs five-group frame labels, target sprite-motion evidence, and stronger player-visible novelty before it can claim maturity.

Promote the Challenge 4 pink-serpentine window into five group labels and tune the runtime path so all groups keep a readable serpentine score lane.
Add high-bonus readability probes so late-stage complexity stays learnable instead of becoming visual noise.

Testing Personas

The platform-level persona vocabulary as applied to Aurora. Platinum owns the generic persona IDs, aliases, seeded execution, and comparison substrate; Aurora owns which scenarios matter and what each persona should prove for this game.

Persona	Testing Role	Expected Behavior	Game-Specific Checks
Beginner novice	Low-skill onboarding and unfairness detector.	Moves less efficiently, misses more challenge opportunities, but should still experience readable cause and effect.	Stage 1, Stage 2 safety, first challenge clarity.
Intermediate advanced	Competent casual-play proxy.	Clears early waves more often and engages capture/rescue and challenge bonuses inconsistently.	Mid-run pressure, challenge hit rate, Stage 4 fairness.
Expert expert	Skilled player proxy.	Reaches deeper stage bands, positions better, and reveals whether reward routes are viable.	Stage 12/14 reward routes, boss/squadron scoring.
Professional professional	High-skill regression guard and release-confidence proxy.	Exploits strong routes without collapsing from unfair timing or broken scoring.	Professional stage-2 checks, long-run progression ordering, late reward windows.

Persona Performance Distribution

Repeated seeded full-run gameplay for the generic Platinum personas. This measures score, stage depth, time alive, losses, and challenge performance as a distribution rather than treating one seeded route as the whole truth.

Audio Theme	auto, aurora-application, galaga-original-reference, galaga-reference-assets	Developer override for phase-resolved audio routing. `aurora-application` uses Aurora's current synthetic application mix. `galaga-original-reference` uses the synthetic classic-leaning approximation. `galaga-reference-assets` plays the extracted Galaga reference clips for the mapped gameplay/challenge/results moments.
Graphics Theme	auto, classic-arcade, aurora-hint, aurora-borealis, aurora-crown	Developer override for the visual atmosphere family. It changes rendered backgrounds and starfield profiles without changing the resolved audio theme.
Starfield Intensity	0.5 to 1.8	Multiplier applied to star brightness so we can tune classic visibility against reference material without rewriting the base theme.
Starfield Speed	0.5 to 1.8	Multiplier applied to live starfield speed so we can compare Aurora against classic Galaga movement references.
