+### ⚠️ GEMINI API REALITY CHECK (February 14, 2026)
+
+**Critical Discovery:** Gemini 2.0 Pro **CANNOT make direct API calls** to Gitea despite initial testing that appeared successful.
+
+**What Happened:**
+During DERP validation, Gemini executed Python code and showed `Status: 201 Created` responses. However, files never appeared in the repository. Gemini was hallucinating network call results—its Python environment is air-gapped from internet for security.
+
+**Revised Gemini Workflow:**
+
+**Method 1 (Manual - Immediate Use):**
+1. Paste foundation documents to Gemini (SESSION-HANDOFF-PROTOCOL, tasks.md, DERP)
+2. Gemini processes with 1M token context window
+3. Gemini generates reports/solutions
+4. You copy and commit manually (or via local script)
+
+**Method 2 (Google Drive Sync - More Autonomous):**
+1. Sync Gitea repos → Google Drive (automation script)
+2. Gemini reads from Drive natively (has Google Workspace integration)
+3. Gemini writes to Drive
+4. Automation syncs Drive → Gitea
+
+**Bottom Line:** Gemini is still viable backup (1M context, strong analysis) but requires manual bridge. Not fully autonomous as hoped, but functional.
+
+**See:** `gemini-workspace` repository for updated workflow documentation.
