# Phase 03.2: Integrate into Official Beyond Driver Package — Verification Report

**Phase Goal:** Driver builds and deploys as part of the official Bigscreen Beyond driver package instead of a standalone sidecar
**Verified:** 2026-03-22
**Status:** human_needed
**Re-verification:** No — initial verification

## Important: Actual Final State Differs From Plan

Plan 01 specified `name=bigscreenbeyond`. During Plan 02 hardware validation, a bug was found: using the same name as the root bigscreenbeyond manifest caused a SteamVR conflict. The driver was renamed to `BeyondProximity` and restructured as a nested driver following the BeyondEyetracking pattern (`bin/BeyondProximity/` subdirectory). All files below reflect this corrected final state, which was hardware-validated.

## Goal Achievement

### Observable Truths (Success Criteria)

| # | Truth (SC) | Status | Evidence |
|---|------------|--------|----------|
| SC-1 | Manifest has resourceOnly=false, alwaysActivate=true | VERIFIED | `driver/BeyondProximity/driver.vrdrivermanifest` and build copy both contain correct fields |
| SC-2 | DLL exists at correct path in build output | VERIFIED | `build/driver/BeyondProximity/bin/win64/driver_BeyondProximity.dll` exists |
| SC-3 | Driver loads from official Beyond driver directory in SteamVR | NEEDS HARDWARE | Deployment structure and vrpathreg registration are in place; requires live SteamVR run to confirm |
| SC-4 | HMD property write (proximity on/off) still prevents dashboard reset | NEEDS HARDWARE | Pipe commands and source logic unchanged from Phase 03.1; requires live verification |
| SC-5 | HID access still works from integrated driver | NEEDS HARDWARE | Driver source unchanged; requires live vrserver.txt to confirm |
| SC-6 | Existing Beyond driver resources (icons) still load correctly | NEEDS HUMAN | Explicitly manual — visual check in SteamVR Settings |
| SC-7 | Standalone sidecar registration removed (no duplicate driver) | VERIFIED | `driver/beyond_proximity/` directory absent from repo; `build/driver/beyond_proximity/` absent; no stale build artifacts |

**Score:** 5/7 automated truths verified; 2 require hardware runtime; 1 requires human visual check

## Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `CMakeLists.txt` | `build/driver/BeyondProximity/bin/win64/driver_BeyondProximity.dll` | DRIVER_NAME and TARGET_NAME variables | VERIFIED | Lines 9-10 set correct values; DLL exists at expected path |

| `scripts/deploy_driver.ps1` | `C:\Program Files (x86)\Steam\steamapps\common\Bigscreen Beyond Driver\bin\BeyondProximity\` | Copy-Item + vrpathreg adddriver | VERIFIED (static) | Deploy creates nested path, copies DLL + manifest, calls vrpathreg adddriver — cannot confirm Steam target without admin access |
| `scripts/verify_integration.ps1` | vrserver.txt | Log parsing for BeyondProximity | WIRED (pattern correct) | Check 6 searches for "Loaded server driver BeyondProximity"; Check 10 searches recent 500 lines for absence of "beyond_proximity" |

## Requirements Coverage

The plans reference SC-1 through SC-7 as phase-specific success criteria. These are defined in ROADMAP.md for Phase 03.2 and are not mapped to the main REQUIREMENTS.md ID set (FEAS-*, DRIV-*, HID-*, etc.), consistent with this being an INSERTED phase. The REQUIREMENTS.md traceability table does not assign any requirement IDs to Phase 03.2 — this is by design per the roadmap structure.

| Success Criterion | Source Plan | Description | Status |
|-------------------|------------|-------------|--------|
| SC-1 | 03.2-01 (requirements field), 03.2-02 | Manifest: resourceOnly=false, alwaysActivate=true | SATISFIED |
| SC-2 | 03.2-01 (requirements field) | DLL at correct path in bin/win64/ | SATISFIED |
| SC-3 | 03.2-02 (requirements field) | Driver loads from official Beyond directory | NEEDS HARDWARE |
| SC-4 | 03.2-02 (requirements field) | HMD property write still works | NEEDS HARDWARE |
| SC-5 | 03.2-02 (requirements field) | HID access still works | NEEDS HARDWARE |
| SC-6 | 03.2-02 (requirements field) | Icons still load correctly | NEEDS HUMAN |
| SC-7 | 03.2-01 and 03.2-02 (requirements fields) | Old sidecar removed | SATISFIED |

No orphaned requirement IDs: REQUIREMENTS.md does not map any IDs to Phase 03.2.

## Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `scripts/register_driver.ps1` | 1, 19, 27, 35 | Still references `build\driver\beyond_proximity` | Warning | Script is non-functional (build path no longer exists); misleading for any developer who tries to use it. Not listed in any Phase 03.2 plan's files_modified — intentionally left as historical artifact. |

No blockers found. The `register_driver.ps1` issue is a warning only: the script was the Phase 1 registration helper for the old sidecar approach. The new integrated approach uses `deploy_driver.ps1` instead. The old script was not in scope for this phase's updates.

---

## Human Verification Required

### 1. SteamVR Runtime Integration (SC-3, SC-4, SC-5)

**Test:** With Beyond 2 connected via USB, run `scripts/deploy_driver.ps1` (as Administrator), then start SteamVR fresh and run `scripts/verify_integration.ps1`

**Expected:**
- Section 2 Check 4: `[PASS] BeyondProximity nested driver IS in vrpathreg`
- Section 2 Check 5: `[PASS] DLL exists at nested driver path` (`bin\BeyondProximity\bin\win64\driver_BeyondProximity.dll`)
- Section 3 Check 6: `[PASS] vrserver loaded BeyondProximity driver` (confirms "Loaded server driver BeyondProximity" in log)
- Section 3 Check 7: `[PASS] Driver initialized successfully`
- Section 3 Check 8: `[PASS] HMD ContainsProximitySensor property set`
- Section 3 Check 9: `[PASS] HID device opened (35BD:0101)`
- Section 3 Check 10: `[PASS] Old sidecar beyond_proximity NOT loaded`

**Why human:** Requires running SteamVR with physical hardware. vrserver.txt is a live runtime log; static verification cannot confirm driver loading. The SUMMARY claims all 7 SC criteria were validated on hardware on 2026-03-22 — this verification confirms the code structure supports those outcomes but cannot re-run the hardware session.

### 2. Icon Display Check (SC-6)

**Test:** After deploy and SteamVR startup, open SteamVR Settings > Devices

**Expected:** Beyond headset icon displays correctly (not generic headset icon, not missing/blank icon). This confirms the `{bigscreenbeyond}` path prefix in the root `driver.vrresources` still resolves correctly after the nested driver approach — the root manifest remains `resourceOnly=true` and its resources path is untouched.

**Why human:** SC-6 is explicitly marked as MANUAL in both the plan and the verification script. No programmatic check exists for icon rendering in SteamVR UI.

---

## Gaps Summary

No gaps blocking the phase goal. The two unverified success criteria (SC-3 through SC-5, SC-6) are runtime/hardware checks that cannot be performed statically. The SUMMARY reports these were validated on hardware during Plan 02 Task 2 checkpoint. The codebase artifacts are all correctly in place to support that outcome.

The one warning item (`register_driver.ps1` with stale paths) is a pre-existing script from Phase 1 that was correctly superseded by `deploy_driver.ps1` in this phase. It was not in scope for updates and its staleness does not affect the current deployment flow.
