 ## The Two Projects
 
 ### Sister repo — minecraft-ai-god (Vanilla)

 - **LLM backend:** Ollama at `192.168.0.179:11434` for the vanilla service. This fork uses `192.168.0.141:11434` (steel141, local GPU) for better throughput on heavier models (gemma3:12b message model, qwen3-coder:30b command model).
 - **Session gateway (this fork only):** The LangGraph-style FastAPI sidecar adds multi-turn memory without requiring a full LangGraph install. Safety enforcement stays in `mc_aigod_paper.py`, not the gateway.
 - **Build templates:** Deterministic templates are tried first for `sudo build/make/create` requests. LLM translation is the fallback. This reduces surprises for structure generation tasks.
+- **Localized retrieval for sudo reasoning (2026-03-17):** `langgraph_gateway.py` now supports a local knowledge corpus (`/var/lib/mc-langgraph-gateway/knowledge`) with index/search/read tools (`local.search`, `local.read`), optional startup bootstrap from Minecraft/Paper docs URLs, and automatic search->read retrieval hop in sudo tool mode before command generation.
+- **Post-deploy behavior check (2026-03-17):** retrieval is active (`tool_trace` shows `local.search` + `local.read`) for `sudo destroy my surroundings`, but generated command remained `execute as <player> run fill ~-5 ~-5 ~-5 ~5 ~5 ~5 air` and produced no useful visible outcome in gameplay (empty/weak RCON feedback). Retrieval alone did not guarantee effective action selection.
+- **Sudo execution hardening follow-up (2026-03-17):** added command-shape normalization for sudo (`execute as <player> run ...` -> `execute at <player> run ...`), blocked execute-wrapper bypass in validator (unsafe inner tails like `gameMode` inside `execute ... run`), and added adaptive destructive fallback for failed `destroy/nuke` intents (absolute `fill ... air` around player + TNT summons / TNT kit fallback when position unavailable).
+- **Sudo effectiveness feedback loop (2026-03-17):** sudo now scores execution effectiveness from RCON results for all intents, reports translated commands + outcomes + ineffective flag back to gateway session memory (`mode=sudo_feedback`, `feedback_only=true`), and gateway stores this feedback without running extra LLM/tool calls.
+- **Lookup contextual memory fix (2026-03-17):** `sudo lookup/search/wiki` now resolves pronoun references (e.g., "that command", "do it again") against the player's most recent executed sudo command, includes that command in lookup context payloads, and passes sudo history into gateway lookup context to improve follow-up reasoning.
+- **Gamemode/effect sudo fix (2026-03-17):** Added `gamemode` to safe prefixes/whitelist and command palette, added syntax normalizer for malformed variants (`gameMode s`, short aliases, missing target) and execute-wrapped gamemode forms; confirmed valid RCON forms are `gamemode <mode> <player>` and `effect give <player> <effect> <duration> <amplifier> [hideParticles]`.
+- **AI-driven build/template flow (2026-03-17):** `process_sudo` now defaults to non-deterministic build planning (legacy deterministic builder templates disabled unless `sudo_deterministic_build_templates=true`), supports AI-emitted `template ...` meta-commands in sudo execution loop, and includes an AI template planner override for build/make/create prompts when initial translation does not emit template workflow steps.
+- **Failed-execution retry pipeline upgrade (2026-03-17):** sudo now runs a generic retry-repair pass on ineffective results before intent fallback. Added TNT-specific repair for malformed `summon tnt ... <count>` outputs (expands into bounded multiple summon commands) and invulnerability-effect repair to valid protection effects. Added `tnt` to destructive-intent keywords so TNT requests can trigger destructive fallback when needed.
+- **God voice update (2026-03-17):** Increased default God persona emphasis on irony, dark humor, and sarcastic one-liners in both command and message system prompts (vanilla + Paper variants) while keeping command strictness unchanged.
