+# OpenClaw Meta Bridge
+
+FastAPI sidecar for Meta Page and Messenger workflows. It normalizes Meta webhooks, stores inbound events and drafts, exposes approval-gated tools, and keeps public sends behind explicit human approval.
+
+## Features
+
+- Meta webhook verification and signature validation.
+- Configurable Page contexts through environment variables.
+- Draft creation for Messenger, comments, Page posts, and Reels.
+- Validation-only lanes for Page posts and Reels.
+- Read-only Page operations endpoints for posts, media, insights, settings, conversations, and comment threads.
+- SQLite-backed audit log and draft lifecycle.
+
+## Configuration
+
+Copy `.env.example` to `.env` and fill in real values. Keep `.env` private.
+
+Page contexts are configured with `META_PAGE_CONTEXTS`, then per-page env vars:
+
+```bash
+META_PAGE_CONTEXTS=healthcare,civic
+META_PAGE_ID_HEALTHCARE=...
+META_PAGE_TOKEN_HEALTHCARE=...
+META_PAGE_NAME_HEALTHCARE="Example Health Services"
+```
+
+The public repo intentionally uses generic sample contexts. Rename contexts and risk rules for your own deployment.
+
+## Local Development
+
+```bash
+python3 -m venv .venv
+. .venv/bin/activate
+pip install -r requirements.txt
+pytest
+uvicorn app.main:app --reload --port 8090
+```
+
+## Safety Notes
+
+- Do not commit `.env`, database files, webhook payload archives, logs, Page tokens, Page IDs from private deployments, or screenshots containing private conversations.
+- Publishing endpoints require `approved_by`; validation-only mode is available for dry runs.
+- Unknown Page IDs fail closed.
