-short_description: Temporary webhook payload inspector
+short_description: Text monitoring with Telegram alerts
 ---
 
-This is a temporary receiver for inspecting the payload sent by Medialogia.
-It does not call DeepSeek, publish messages to Telegram, or run the old application.
-Access to sample payloads is protected by WEBHOOK_SECRET.
-See SETUP_RU.txt for instructions and limitations.
+Receives Medialogia webhooks, posts all publications to Telegram, and uses an
+independent DeepSeek classifier for potential topic alerts. Text only; no image,
+OCR, subtitle, or original-page fetching. The default model is deepseek-flash
+with thinking disabled. A positive result is a signal for a person to assess.
 
+Set these Space Secrets: WEBHOOK_SECRET, TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID,
+DEEPSEEK_API_KEY and ALERT_MENTIONS. CLASSIFIER_PROMPT overrides the generic
+default instructions and belongs in a Secret when it contains internal context.
+Never commit credentials or confidential classifier instructions to this repo.
+
+GET /health reports configuration. POST /medialogia/WEBHOOK_SECRET accepts a
+single Medialogia post or a JSON array of posts. GET /status/WEBHOOK_SECRET
+reports queue counters. Substitute the actual secret privately; do not publish
+these URLs. The earlier /samples/ route now returns status, not raw payloads.
+
+By default this is a pilot using SQLite under /tmp. Queue state and deduplication
+may be lost when a Space restarts or rebuilds. For durable state set the Secret
+DATABASE_URL to an external PostgreSQL connection string with TLS. No database
+or paid hosting is provisioned automatically. Run only one app instance against
+the database. Free Space sleeping and delivery gaps remain possible regardless
+of database choice. Keep existing monitoring active during the pilot.
+
+No exactly-once Telegram guarantee: if an API send succeeds but its response
+or the subsequent database write is lost, a retry can duplicate a publication
+or an alert. AI failures remain pending and are retried, never recorded as NO.
+Normal posts are sent silently; alerts request a notification, which still
+depends on recipients' Telegram settings. Mentions are explicit @usernames.
+Post text is split across messages when necessary; its complete text is checked.
