 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.
 
+The language selected during Security Manager onboarding is enforced across direct chat, multi-tool answers, tool-loop finalization, dynamic presence, and proactive sweep alerts. This does not depend on the model deciding to read the profile first. Server-generated labels such as priority, evidence, and tool traces are localized as well.
+
+#### Dynamic DAVE Presence
+
+`DAVE_PRESENCE_ENABLED=true` lets DAVE initiate Telegram conversations without fixed daily times. Evaluations occur at randomized intervals and can be pulled forward by material sweep changes. DAVE considers current data freshness, source integrity, recent changes, evidence, the encrypted Security Manager profile, time since your last interaction, and whether another message would add value. It may send a relevant warning, situation update, evidence-grounded all-clear, practical suggestion, or one natural context question. It stays silent when a message would only add noise.
+
+Dynamic presence respects profile quiet hours, a daily message cap, a minimum gap between messages, and an idle period after your own chat activity. Evaluation timing and counters persist in `runs/dave-presence-state.json`, preventing restart spam. Scheduled presence cannot execute mutating tools or bypass confirmation. This feature is opt-in because it consumes LLM requests and sends unsolicited Telegram messages.

+## Dynamic DAVE Presence
+
+- Gitea issue #70 was closed by merged PR #71. Production merge commit: `ca68541adf9931e311f1a79a09cb87b3cae85928`.
+- Implementation commit: `08b6016 feat: add dynamic autonomous DAVE presence`; handoff commit: `f2d8e89`.
+- The implementation deliberately uses no fixed daily schedule. It evaluates at randomized intervals, is pulled forward by material/critical sweep deltas, delays itself after operator chat activity, and lengthens quiet periods.
+- Hard controls: profile quiet hours, daily cap, minimum message gap, bounded evaluation interval, persisted state in `runs/dave-presence-state.json`, and agent-core rejection of mutating tools outside operator-initiated chat.
+- Presence can produce a grounded warning, update, all-clear, practical suggestion, or one useful question; it stays silent when another message would add noise. It never claims consciousness or continuous observation.
+- New env keys start with `DAVE_PRESENCE_`; the repository default remains opt-in.
+- Local lightweight verification passed: Node syntax checks, `package.json` parse, Compose config, and `git diff --check`. Heavy tests/build were not run locally per kit policy.
+- PR runs 915-916 and production runs 917-919 passed, including unit tests, Compose validation, Docker build/publish, release dry-run, and template compliance.
+- Dockge was updated from the Gitea Registry and explicitly configured with `DAVE_PRESENCE_ENABLED=true`, max 4 messages/day, 75-minute minimum gap, randomized 45-180 minute evaluation bounds, 60-minute post-interaction idle delay, and a 5-minute timer resolution.
+- Live `/api/health` reported `davePresence.enabled=true`, `running=true`, `dynamic=true`, `sentToday=0`, a variable `nextEvaluationAt`, the existing encrypted profile preserved, and no sweep error. The container reported `running/healthy`.
+- Live verification then exposed issue #73: an invalid optional profile timezone caused `lastReason=invalid_timezone`. PR #74 fixed runtime resolution to fall back to `DAVE_PRESENCE_TIMEZONE` without logging or modifying encrypted profile data. Merge commit: `f0a8162202bfe0a0a8ed2a00dc4f0f7092677eea`.
+- PR runs 925-926 and production runs 927-929 passed. After redeployment and the startup timer, live health reported `lastReason=not_due` instead of `invalid_timezone`, with dynamic presence running, the profile preserved, the container healthy, and no sweep error.
+
 ## Latest Completed Work
 
+- Issue #79 / PR #80 fixed proactive DAVE alerts ignoring the onboarding profile language. The screenshot showed German dynamic presence followed by an English `[AGENT PRIORITY]` alert. Merge commit: `59b496aee19b446a7cdeae74d119778cfbd92d8f`.
+- The validated profile language is now an explicit required runtime parameter for direct provider chat, multi-tool reasoning, final-only synthesis, dynamic presence, and proactive sweep analysis. This no longer depends on the model choosing to call `get_security_profile`.
+- Server-generated wrappers are localized (`DAVE // PRIORITÄT`, `Belege`, `Werkzeuge`, `AKTIV`). Provider, tool-finalization, and presence language tests were added. PR runs 959-960 and production runs 961-963 passed.
+- The registry image was redeployed to Dockge. Live verification read only the encrypted profile language code and confirmed `de`; the container was `running/healthy`, profile persisted, agent and presence enabled, and no sweep error was present.
+
+- Issue #76 / PR #77 fixed a second local-model protocol leak: ChatML-style output such as `<|tool_call>call:get_evidence{query:"...",limit:5}<tool_call|>` was previously treated as user-facing text. Merge commit: `7f140021f037cbc351c9a3b39a5eb3610bfc4939`.
+- The controlled agent now parses bounded tagged calls into the normal allowlisted tool path without `eval`, recognizes tagged JSON envelopes, and treats malformed protocol-like output as a repairable protocol error. Tool tags are never accepted as final Telegram text.
+- The exact observed Russia-query format and a malformed-tag variant are regression fixtures. PR runs 935-936 and production runs 937-939 passed.
+- The registry image was redeployed to Dockge. Live health reported `running/healthy`, Telegram agent enabled with 14 tools, dynamic DAVE presence enabled, encrypted profile preserved, and no sweep error.
