 The Security Manager uses the profile to rank proximity, severity, time horizon, household impact, mobility constraints, and infrastructure dependencies. Its prompt requires separation of verified facts, official guidance, source reports, and inference. It is an intelligence aid, not an emergency service; urgent responses direct the operator to appropriate local authorities without claiming guaranteed safety.
 
+The Security Manager's conversational identity is **DAVE**, a synthetic security-management construct. DAVE adapts language, formality, directness, answer length, formatting, and technical depth to the operator's current message and bounded chat history. Explicit style requests take priority. The adaptation does not copy spelling mistakes, hostility, panic, or unsupported certainty, and urgent safety instructions remain concise and unambiguous. DAVE does not claim human emotions, consciousness, a body, or access beyond the terminal's allowlisted tools.

 ### Discord Bot (Two-Way)
 
 Intelligence Terminal also supports Discord as a full-featured bot with slash commands and rich embed alerts. It mirrors the Telegram bot's capabilities with Discord-native formatting.

 - PR validation runs 883-886 passed. Production merge commit `c0afc6d2e88b7602148d786dd249351323885ac2` passed build/publish run 887, release dry-run 888, and template compliance 889.
 - Registry tags `latest`, `20260705`, and `c0afc6d2e88b7602148d786dd249351323885ac2` were verified through the Gitea Package API on 2026-07-05.
 - The Dockge stack at `C:\docker\intelligence-terminal` was updated from the registry image. A cryptographically random `SECURITY_PROFILE_ENCRYPTION_KEY` was added without printing it. Live health reported the container healthy, LiteLLM configured, Telegram AI and the 14-tool agent enabled, and the encrypted profile store configured/available with no profile yet.
+- Issue #64 fixed a local-model protocol leak where an exhausted tool loop could expose a raw `tool_call` JSON object as the Telegram answer. PR #65 merged as `e47c23e685d833d5f7433dc27b0834854c8c6152`.
+- Exhausted loops now switch to a separate tool-free finalization prompt, allow one bounded repair attempt, and fail closed with a localized user-facing message if the model still requests tools. Internal protocol JSON is never returned as the answer.
+- PR runs 895-896 and production runs 897-899 passed. The registry `latest` image was deployed to Dockge; live health reported `running/healthy`, 14 tools enabled, no sweep error, and the encrypted Security Manager profile preserved (`profileExists=true`).
+- Issue #67 / PR #68 added DAVE as the consistent synthetic Security Manager identity across the tool agent, tool-free finalizer, provider-only chat, and first-start language prompt. Production merge: `c07a65231ffc6b4d2f0c823b91aaf2eb13900e05`.
+- DAVE adapts language, formality, directness, verbosity, sentence length, formatting, and technical depth from the newest message plus bounded chat history. It does not imitate errors, hostility, panic, discriminatory language, or unsupported certainty, and it never claims human consciousness, emotions, a body, or access beyond allowlisted tools.
+- PR runs 905-906 and production runs 907-909 passed. The new registry image was deployed to Dockge; live health remained `running/healthy`, the 14-tool agent was enabled, no sweep error was present, and the encrypted profile persisted.

 - If a new Codex environment sees non-fast-forward branch pushes, fetch first and preserve remote commits. Do not force-push without explicit approval.
 - A production deployment must add `SECURITY_PROFILE_ENCRYPTION_KEY` before expecting first-start onboarding. A changed or lost key intentionally fails closed and does not overwrite existing ciphertext.
 - Security Manager first-start onboarding remains intentionally incomplete until the operator answers the language and consent prompts in Telegram; no personal profile is created automatically.
