| 2 | + |
| 3 | +## [2026-02-02T15:43] Session Start: ses_3e10cdd23ffel74HDj7bwvkaxG |
| 4 | + |
| 5 | +### Context |
| 6 | +- Plan: Maximum Haptic Feedback Implementation |
| 7 | +- Goal: actuate(15, 2.0) for maximum haptic strength |
| 8 | +- Approach: Swift binary only (plugin-only, no npm) |
| 9 | + |
| 10 | +## [2026-02-03T00:50] Task 1: Restore Swift Binary Source Files |
| 11 | + |
| 12 | +### Completed Actions |
| 13 | +- ✓ Created `native/` directory |
| 14 | +- ✓ Restored `native/HapticEngine.swift` from commit 9cdb8b8 |
| 15 | +- ✓ Restored `native/build.sh` from commit 9cdb8b8 |
| 16 | +- ✓ Verified MTActuatorActuate API usage |
| 17 | + |
| 18 | +### Verification Results |
| 19 | +- ✓ File exists: `native/HapticEngine.swift` |
| 20 | +- ✓ File exists: `native/build.sh` |
| 21 | +- ✓ API usage: MTActuatorActuate found |
| 22 | +- ✓ Haptic intensity: actuate(15, 2.0) - CORRECT |
| 23 | + |
| 24 | +### Key Findings |
| 25 | +- ACTUATION_STRONG = 15 (very strong haptic) |
| 26 | +- Default intensity = 2.0 (maximum) |
| 27 | +- Intensity clamped to [0.0, 2.0] range |
| 28 | +- Swift binary uses IOKit + MultitouchSupport framework |
| 29 | +- Universal binary build (arm64 + x86_64) |
| 30 | + |
| 31 | +### Build Configuration |
| 32 | +- Targets: arm64-apple-macosx12.0, x86_64-apple-macosx12.0 |
| 33 | +- Frameworks: IOKit, CoreFoundation, MultitouchSupport |
| 34 | +- Output: Universal binary via lipo |
| 35 | + |
| 36 | +### Next Steps |
| 37 | +- Task 2: Build the binary using build.sh |
| 38 | +- Task 3: Integrate with OpenCode plugin |
| 39 | + |
| 40 | +## [2026-02-03T00:50] Task 3: Plugin Files Restoration Complete |
| 41 | + |
| 42 | +### Files Restored from commit 9cdb8b8 |
| 43 | +1. ✓ `opencode-plugin/louder.js` - OpenCode plugin with HapticEngine binary spawn |
| 44 | +2. ✓ `hooks/louder-hook.js` - Claude Code hook with haptic configuration |
| 45 | +3. ✓ `src/core/sound.ts` - Sound support module |
| 46 | + |
| 47 | +### Haptic Values Verified |
| 48 | +**OpenCode Plugin (`opencode-plugin/louder.js`):** |
| 49 | +- Line 87: `engine.write(\`15,${intensity}\`)` - Actuation ID 15 |
| 50 | +- Line 84: `async function playHaptic(intensity = 2.0)` - Default intensity 2.0 |
| 51 | +- Line 123: `await notify("success", 2.0)` - Confirms max haptic on success |
| 52 | + |
| 53 | +**Claude Hook (`hooks/louder-hook.js`):** |
| 54 | +- Line 61: `const ACTUATION_STRONG = 15` - Maximum actuation ID |
| 55 | +- Line 70: `success: 2.0` - Maximum intensity for success events |
| 56 | +- Line 178: `const actuationID = HAPTIC_ACTUATION_MAP[parsed.type] || ACTUATION_STRONG` - Uses max by default |
| 57 | + |
| 58 | +### Key Findings |
| 59 | +- Both plugins already configured for maximum haptic (15, 2.0) |
| 60 | +- OpenCode plugin spawns HapticEngine binary as subprocess |
| 61 | +- Claude hook uses constants for easy configuration |
| 62 | +- No NAPI module files restored (plugin-only approach confirmed) |
| 63 | +- Sound support restored separately (no haptic logic in sound.ts) |
| 64 | + |
| 65 | +### Next Steps |
| 66 | +- Task 1: Restore Swift source files (native/HapticEngine.swift, native/build.sh) |
| 67 | +- Task 2: Build universal binary from restored source |
| 68 | +- Task 4: Final verification of haptic values (should already be correct) |
| 69 | + |
| 70 | +## [2026-02-03T01:15] Task 2: Build Universal Binary for HapticEngine |
| 71 | + |

| 76 | +- ✓ Compiled x86_64 architecture (x86_64-apple-macosx12.0) |
| 77 | +- ✓ Created universal binary via lipo |
| 78 | +- ✓ Verified binary format and permissions |
| 79 | + |
| 80 | +### Verification Results |
| 81 | +- ✓ PASS: Universal binary (arm64 + x86_64) |
| 82 | +- ✓ PASS: Binary is executable (chmod +x applied) |
| 83 | +- ✓ Binary size: 151K (reasonable for Swift binary with frameworks) |
| 84 | +- ✓ Architecture details: x86_64 and arm64 both present |
| 85 | +- ✓ MultitouchSupport framework linked correctly |
| 86 | + |
| 87 | +### Build Output Summary |
| 88 | +``` |

| 122 | +- ✓ Read specific lines to confirm exact values |
| 123 | + |
| 124 | +### Verification Results - PASS (All Maximum) |
| 125 | + |
| 126 | +**OpenCode Plugin (`opencode-plugin/louder.js`):** |
| 127 | +- Line 84: `async function playHaptic(intensity = 2.0)` ✓ Default intensity = 2.0 (MAXIMUM) |
| 128 | +- Line 87: `engine.write(\`15,${intensity}\`)` ✓ Actuation ID = 15 (MAXIMUM) |
| 129 | +- Line 91: `async function notify(soundType = "success", hapticIntensity = 2.0)` ✓ Confirms 2.0 |
| 130 | +- Line 123: `await notify("success", 2.0)` ✓ Success event uses max haptic |
| 131 | + |
| 132 | +**Claude Hook (`hooks/louder-hook.js`):** |
| 133 | +- Line 61: `const ACTUATION_STRONG = 15;` ✓ ACTUATION_STRONG = 15 (MAXIMUM) |
| 134 | +- Line 62: `const ACTUATION_WEAK = 6;` (for reference) |
| 135 | +- Line 65: `success: ACTUATION_STRONG,` ✓ Maps success to 15 |
| 136 | +- Line 70: `success: 2.0,` ✓ DEFAULT_INTENSITY.success = 2.0 (MAXIMUM) |
| 137 | +- Line 71: `error: 1.5,` (for reference) |
| 138 | +- Line 178: `const actuationID = HAPTIC_ACTUATION_MAP[parsed.type] || ACTUATION_STRONG;` ✓ Defaults to 15 |
| 139 | + |
| 140 | +### Key Findings |
| 141 | +- ✓ BOTH plugins already configured for MAXIMUM haptic feedback |
| 142 | +- ✓ OpenCode plugin: actuation 15, intensity 2.0 |
| 143 | +- ✓ Claude hook: ACTUATION_STRONG=15, DEFAULT_INTENSITY.success=2.0 |
| 144 | +- ✓ NO UPDATES NEEDED - values are already at maximum |
| 145 | +- ✓ Success events trigger strongest haptic (15, 2.0) |
| 146 | +- ✓ Error events use medium haptic (6, 1.5) for distinction |
| 147 | + |
| 148 | +### Conclusion |
| 149 | +Task 3 findings confirmed: Both plugins have maximum haptic values already set. |
| 150 | +No code changes required. Verification complete. |
| 151 | + |
| 152 | +## [2026-02-03T01:30] Task 5: Bundle Binary with Plugins |

| 181 | + ] |
| 182 | +} |
| 183 | +``` |
| 184 | +- **Result**: Finds binary at `~/.config/opencode/native/HapticEngine` (already present) |
| 185 | +- **Status**: ✓ WORKING - Binary accessible via first search location |
| 186 | +
|
| 187 | +**Binary Path Resolution - Claude Hook:** |
| 188 | +```javascript |
| 189 | +function getHapticEnginePath() { |
| 190 | + const currentDir = dirname(fileURLToPath(import.meta.url)); // hooks/ |
| 191 | + return join(currentDir, "..", "native", "HapticEngine"); // ../native/HapticEngine |
| 192 | +} |
| 193 | +``` |
| 194 | +- **Result**: Resolves to `native/HapticEngine` (project root) |
| 195 | +- **Status**: ✓ WORKING - Binary exists at resolved path |
| 196 | +
|
| 197 | +### Key Findings |
| 198 | +
|
| 199 | +**OpenCode Plugin:** |
| 200 | +- Uses multi-location search strategy |
| 201 | +- First location: `~/.config/opencode/native/HapticEngine` ✓ EXISTS |
| 202 | +- Binary already present in OpenCode config directory |
| 203 | +- No changes needed - plugin-only distribution ready |
| 204 | +
|
| 205 | +**Claude Code Hook:** |
| 206 | +- Uses relative path from hooks directory |
| 207 | +- Path: `../native/HapticEngine` (resolves to project root) |
| 208 | +- Binary exists at expected location |
| 209 | +- No changes needed - plugin-only distribution ready |
| 210 | +
|
| 211 | +**Plugin-Only Distribution Status:** |
| 212 | +- ✓ Binary bundled in project: `native/HapticEngine` |
| 213 | +- ✓ OpenCode plugin can find binary via config directory |
| 214 | +- ✓ Claude hook can find binary via relative path |

| 222 | +
|
| 223 | +**No path updates needed** - both plugins have working binary search logic: |
| 224 | +1. OpenCode plugin: Searches multiple locations, finds binary in `~/.config/opencode/native/HapticEngine` |
| 225 | +2. Claude hook: Uses relative path from hooks directory to project root `native/HapticEngine` |
| 226 | +
|
| 227 | +**Plugin-only distribution verified**: Binary is pre-built, no user compilation required. |
