Goal Achievement
Observable Truths (from ROADMAP.md Success Criteria)
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | WS2801 (160 LEDs, SPI) and SK6812 (300 LEDs, RMT/RGBW) both illuminate correctly and simultaneously with no flicker from WiFi interference | VERIFIED | led_driver.cpp: stripWand.Show() (RMT DMA) + stripSchrank.Show() (SPI 2MHz) in showBothStrips(); esp_wifi_set_ps(WIFI_PS_NONE) in main.cpp L36; hardware checkpoint in 01-01-SUMMARY.md: "Zero visible flicker during 300-packet UDP burst test" — APPROVED |
| 2 | Sending a UDP JSON command triggers named animation on correct strip within 50ms | VERIFIED | wifi_server.cpp: AsyncUDP.onPacket -> xQueueSendFromISR -> parseTask -> commandQueue; animation_engine.cpp: queue drained at start of each 50fps frame (20ms worst case + parse overhead); hardware checkpoint in 01-04-SUMMARY.md: "UDP JSON chase command triggers Wand strip within 50ms — PASS" |
| 3 | All 8 built-in animations run on either zone without crashing | VERIFIED | ANIM_REGISTRY[8] in animation_engine.cpp: chase, pulse, rainbow, strobe, color_wash, breathe, sparkle, gradient_sweep — all 8 .cpp files exist in firmware/src/animations/; 01-04 hardware checkpoint: "All 8 animations run visually distinct on both zones — PASS"; "10-minute continuous operation with no crash or watchdog reset — PASS" |
| 4 | Each zone can be commanded independently — different animations run on Schrank and Wand simultaneously | VERIFIED | applyCommand() in animation_engine.cpp: routes by cmd.zone (SCHRANK / WAND / ALL) to independent ZoneState structs; parseCommand() in protocol.cpp: zones parsed at L33-37; hardware checkpoint: "Schrank and Wand run different animations simultaneously — PASS" |
| 5 | Animation parameters (color/RGBW, speed, intensity) visibly change behavior when included in JSON command | VERIFIED | AnimParams struct in protocol.h: speed/intensity/colors/direction; all animations apply params.intensity * g_brightness as brightness factor and use params.speed to scale timing; applyBrightnessW/R() in led_driver.cpp enforces brightness cap; hardware checkpoint: "Speed, color, intensity parameters visibly change behavior — PASS" |

Data-Flow Trace (Level 4)
This phase produces no dynamic data rendering (no UI components). All data flows are hardware signal writes — LED strip output is verified by hardware acceptance test, not programmatic data-flow tracing. Level 4 is not applicable for embedded C++ firmware.
Behavioral Spot-Checks
Step 7b: SKIPPED — No runnable entry points on VPS. Firmware targets ESP32-C3 hardware; pio run is not available in this environment. Hardware acceptance tests documented in plan summaries serve as the behavioral validation record.
Requirements Coverage
| Requirement | Source Plan(s) | Description | Status | Evidence |
|---|---|---|---|---|
| FW-01 | 01-01, 01-04 | ESP32-C3 drives WS2801 (160, SPI) and SK6812 (300, RMT/RGBW) simultaneously | SATISFIED | led_driver.cpp: both strips initialized and driven in showBothStrips(); hardware PASS in 01-01-SUMMARY.md |
| FW-02 | 01-02, 01-04 | ESP32-C3 receives JSON commands over UDP and executes named animations | SATISFIED | wifi_server.cpp + protocol.cpp: AsyncUDP listener on port 4210, JSON parsed into LedCommand, dispatched via commandQueue; hardware PASS in 01-04-SUMMARY.md |
| FW-03 | 01-03, 01-04 | At least 8 built-in animations (Chase, Pulse, Rainbow, Strobe, Color Wash, Breathe, Sparkle, Gradient Sweep) | SATISFIED | ANIM_REGISTRY[8] in animation_engine.cpp, all 8 .cpp files exist and are substantive; hardware PASS |
| FW-04 | 01-03, 01-04 | Each animation accepts configurable parameters (color/RGBW, speed, intensity) | SATISFIED | AnimParams struct with speed/intensity/colors[8][4]/direction; all animations apply params; hardware PASS |
| FW-05 | 01-02, 01-04 | Both LED zones (Schrank/Wand) are independently controllable via JSON protocol | SATISFIED | applyCommand() routes Zone::SCHRANK/WAND/ALL to independent ZoneState structs; hardware PASS |
All 5 phase requirements (FW-01 through FW-05) are satisfied. No orphaned requirements — REQUIREMENTS.md maps FW-01 through FW-05 exclusively to Phase 1 and all are claimed by plans in this phase.
Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|---|---|---|---|---|
firmware/src/wifi_server.cpp |
49 | buildStatusResponse("unknown", "unknown", 40) — hardcoded animation names and brightness in STATUS response |
Warning | STATUS command returns incorrect current state. Documented as known stub in 01-02-SUMMARY.md. Not a Phase 1 requirement; STATUS accuracy is a quality issue for Phase 2 to address when Pi-side needs live state. No animations are blocked. |
Classification: The STATUS stub is a Warning (incomplete), not a Blocker. FW-01 through FW-05 do not require accurate STATUS responses. The stub does not prevent any animation from running or any command from being processed.
No TODO/FIXME/placeholder comments found in firmware source. No empty return patterns in animation or core files. All animation implementations are substantive (29–54 lines each with real per-pixel logic).
Human Verification Required
1. Visual Animation Distinctiveness
Test: Flash firmware to ESP32-C3 SuperMini, send each of the 8 animation names via UDP to both zone:wand and zone:schrank
Expected: Each animation produces a visually distinct pattern — chase shows a moving window, rainbow shows HSV color sweep, strobe flickers on/off, sparkle shows random flashes, pulse/breathe show sine wave envelopes at different rates, color_wash fades between palette colors, gradient_sweep shows a two-color gradient moving along the strip
Why human: Per-pixel visual output cannot be verified programmatically without connected hardware; code review confirms the logic is correct but a brief visual check confirms no silent rendering errors
2. STATUS Response Wiring Decision
Test: Send {"v":1,"cmd":"status"} while an animation is running
Expected (current): Response returns {"v":1,"status":"ok","wand":"unknown","schrank":"unknown","brightness":40} — hardcoded stub values
Expected (fixed): Response would return actual current animation names and brightness level
Why human: Determine whether accurate STATUS response is needed before Phase 2 begins, or whether Phase 2 plan should include wiring zoneWand.animName, zoneSchrank.animName, and g_brightness into buildStatusResponse(). This requires a product decision, not a code fix.
Gaps Summary
No gaps blocking the phase goal. All 5 observable truths verified. All 22 required artifacts exist, are substantive, and are correctly wired into the build. All 5 firmware requirements (FW-01 through FW-05) are satisfied with hardware acceptance test evidence.
One known stub exists (buildStatusResponse hardcodes "unknown"/"unknown"/40) but it was documented explicitly in 01-02-SUMMARY.md, is not required by any FW-0x requirement, and does not prevent the phase goal from being achieved. It is flagged as a Warning for Phase 2 planning.
