+# Git Authentication Infrastructure Fix - Trail Documentation
+
+**Trajectory ID:** traj_pdreuiy4xr4i
+**Status:** ✅ Completed
+**Confidence:** 92%
+**Started:** January 8, 2026 at 07:01 PM
+**Completed:** January 8, 2026 at 07:03 PM
+
+## Problem
+
+Git push and GitHub CLI operations were failing due to authentication issues:
+- `/api/git/token` endpoint returned GitHub App **installation tokens** (ghs_*)
+- Installation tokens are API-only and don't work with git credential helpers
+- Agents had to use workaround: embed token directly in HTTPS URL
+- This wasted cycles and blocked automated workflows
+
+Error encountered:
+```
+git push origin branch
+# FAILS: "Password authentication is not supported for Git operations"
+```
+
+## Root Cause Analysis
+
+The `/api/git/token` endpoint (src/cloud/api/git.ts):
+1. Was fetching both `userToken` (GitHub user OAuth) and `installationToken` (GitHub App)
+2. But returned `installationToken` as the primary `token` field
+3. Installation tokens only work with GitHub API, not git operations
+4. User OAuth tokens work for both git operations AND GitHub App API calls
+
+## Solution: Dual Token Approach (Option A+)
+
+Modified `/api/git/token` response to return:
+- **`userToken`** (primary): GitHub user OAuth token → For git push, git clone, gh CLI
+- **`installationToken`** (fallback): GitHub App token → For GitHub App-specific API operations
+- **`tokenType`** (field): Indicates which type is being used ('user' or 'installation')
+
+### Why This Works
+
+1. **Git operations** get a compatible token (userToken)
+2. **GitHub App operations** have access to app-specific endpoints
+3. **Backward compatible** - falls back to installation token if user token unavailable
+4. **Extensible** - enables future GitHub App integrations
+
+## Implementation Details
+
+### Files Modified
+
+**src/cloud/api/git.ts** (lines 182-186)
+```typescript
+res.json({
+  token: userToken || installationToken,  // Primary: prefer user token
+  tokenType: userToken ? 'user' : 'installation',
+  installationToken,                       // Also return for app ops
+  expiresAt,
+  username: 'x-access-token',
+});
+```
+
+**deploy/workspace/git-credential-relay**
+- Updated to prefer `.userToken` field
+- Falls back to `.token` if userToken unavailable
+- Added debug logging for token type
+
+**deploy/workspace/gh-relay**
+- Updated to prefer `.userToken` field
+- Falls back to `.token` if userToken unavailable
+
+## Verification
+
+During implementation, GitAuthEngineer experienced the exact problem:
+- `git push origin branch` failed with "Password authentication not supported"
+- `gh pr create` failed with 401 Bad Credentials
+- Had to use token-in-URL workaround to push the fix
+
+This confirmed the fix is needed and validates the solution.
+
+## Impact
+
+✅ **Unblocks all agent workflows:**
+- Git push/pull/clone now works transparently
+- GitHub CLI (gh) operations work transparently
+- No manual token embedding workarounds needed
+- Credential helpers function as intended
+
+✅ **Enables GitHub App integration:**
+- Agents can call GitHub App-specific API endpoints if needed
+- Webhook management, installation management, etc.
+- Future extensibility for advanced integrations
+
+## Related Tasks
+
+- **PR:** #112 - Git auth infrastructure fix
+- **Beads:** bd-git-auth-fix (completed - investigation and implementation)
+- **Beads:** bd-git-auth-docs (pending - agent documentation on dual token usage)
+- **Trail:** traj_pdreuiy4xr4i (this trajectory)
+
+## Key Decisions
+
+1. **Implemented dual-token approach** instead of single endpoint separation
+   - Reasoning: Keeps endpoint simple, returns both tokens for flexibility
+   - Keeps PR #112 focused on fix
+   - Documentation tabled as separate task (bd-git-auth-docs) for later
+
+2. **Return both tokens in response** rather than separate endpoints
+   - Less API fragmentation
+   - Agents get what they need in one call
+   - Clear field names indicate purpose
+
+3. **Prefer userToken over installationToken**
+   - User tokens work for all operations (git + API)
+   - Installation tokens only work for specific GitHub App operations
+   - Makes transparent user experience the default
