+# Fix: Kind 30078 `d=agent_config` Publish Gaps
+
+## Problem
+
+The agent stores its admin pubkey and DM protocol in a NIP-44 self-encrypted kind 30078 replaceable event (`d=agent_config`). This event is critical for the `--nsec`-only startup path (used by systemd services) to recover the admin identity.
+
+**Multiple startup paths fail to publish this event**, causing:
+- Agents installed via wizard "Install Service" to lose their admin pubkey on restart
+- Agents recovering on new servers to use stale/old admin pubkeys from relays
+- Agents with genesis files to silently ignore newer kind 30078 values
+
+## Affected Files
+
+- `src/setup_wizard.c` — wizard flows
+- `src/main.c` — main startup logic
+
+## Fixes
+
+### Fix A: `new_agent_flow` — publish before service install
+**File:** `src/setup_wizard.c` ~line 2184  
+**Problem:** When user chooses "Install systemd service" in new agent flow, `persist_runtime_config_to_nostr_wizard_online` is never called. The service starts with `--nsec` only and has no kind 30078 to recover from.  
+**Fix:** Call `persist_runtime_config_to_nostr_wizard_online(cfg)` before `install_system_service_with_dedicated_user()`. Fail the install if publish fails (same pattern as existing_agent_flow).
+
+### Fix B: `new_agent_flow` — publish before "boot now" return
+**File:** `src/setup_wizard.c` ~line 2177  
+**Problem:** When user chooses "Boot now", the wizard returns `SETUP_WIZARD_RC_BOOTSTRAP` and relies on `main()` to publish later. This works but is fragile — if the bootstrap publish in `main()` fails, the kind 30078 is never created.  
+**Fix:** Call `persist_runtime_config_to_nostr_wizard_online(cfg)` before returning 0. This is belt-and-suspenders — `main()` will also publish, but the wizard ensures it happens at least once. If the wizard publish fails, log a warning but continue (non-fatal since main will retry).
+
+### Fix C: `existing_agent_flow` — always publish before service install
+**File:** `src/setup_wizard.c` ~line 2368  
+**Problem:** `persist_runtime_config_to_nostr_wizard_online` is only called `if (config_changed)`. If the user accepts the recovered config as-is, the kind 30078 is not re-published. The event may have been lost from relays.  
+**Fix:** Remove the `config_changed` gate. Always call `persist_runtime_config_to_nostr_wizard_online(cfg)` before installing the service. Kind 30078 is a replaceable event, so re-publishing is safe and idempotent.
+
+### Fix D: `existing_agent_flow` — always return BOOTSTRAP
+**File:** `src/setup_wizard.c` ~line 2364  
+**Problem:** When user chooses "Boot now" and `config_changed == 0`, the flow returns `SETUP_WIZARD_RC_EXISTING` which means `bootstrap_mode = 0` in `main()`. If `first_run = 0` (kind 10002 exists), `persist_runtime_config_to_nostr` is skipped.  
+**Fix:** Always return `SETUP_WIZARD_RC_BOOTSTRAP` from the "boot now" path, regardless of `config_changed`. This ensures `main()` always re-publishes the kind 30078. The wizard has all the config in memory — it should always be treated as authoritative.
+
+### Fix E: `persist_runtime_config_to_nostr_wizard_online` — ensure relay delivery
+**File:** `src/setup_wizard.c` ~line 1159  
+**Problem:** The function publishes the event and immediately calls `nostr_handler_cleanup()`. The event may not have been delivered to relays yet (fire-and-forget).  
+**Fix:** Add a brief poll loop (e.g., 2-3 seconds of `nostr_handler_poll()`) after the publish call and before `nostr_handler_cleanup()` to give the event time to propagate. This matches the pattern used elsewhere for relay operations.
+
+### Fix F: `main()` — always fetch kind 30078 and compare
+**File:** `src/main.c` ~line 847 (`recover_missing_runtime_config_from_nostr`)  
+**Problem:** The recovery only runs when `admin_config_is_complete()` returns false. If a genesis file provides an admin pubkey, the kind 30078 is never checked, even if it has a different (newer) value.  
+**Fix:** Always fetch the kind 30078 `d=agent_config` regardless of whether the genesis already provided values. Compare the fetched admin_pubkey with the loaded one. If they differ, log a `DEBUG_WARN` with both values. Genesis wins (operator intent), but the warning makes the conflict visible in logs.
+
+### Fix G: `main()` — always re-publish kind 30078
+**File:** `src/main.c` ~line 1152  
+**Problem:** `persist_runtime_config_to_nostr` only runs when `bootstrap_mode || first_run`. On subsequent runs, the kind 30078 is never refreshed. If relays purge the event, it's gone.  
+**Fix:** Move `persist_runtime_config_to_nostr(&cfg)` outside the `if (bootstrap_mode || first_run)` block so it runs on every startup. Kind 30078 is a replaceable event — re-publishing is safe, idempotent, and ensures relay persistence. Log the result but don't fail startup if it doesn't succeed.
+
+## Execution Order
+
+1. Fix E first (relay delivery) — this makes all other wizard publishes more reliable
+2. Fixes A + B (new_agent_flow) — the most critical bug
+3. Fixes C + D (existing_agent_flow) — second most critical
+4. Fix G (always re-publish in main) — ensures long-term relay persistence
+5. Fix F (conflict detection) — nice-to-have logging improvement
+
+## Testing
+
+- Wizard → New Agent → Install Service: verify kind 30078 exists on relays after service starts
+- Wizard → New Agent → Boot: verify kind 30078 exists on relays
+- Wizard → Existing Agent → Install Service (no changes): verify kind 30078 re-published
+- Wizard → Existing Agent → Boot (no changes): verify kind 30078 re-published
+- `--nsec` only restart: verify kind 30078 recovered and re-published
+- `--config genesis.jsonc` with different admin than kind 30078: verify warning logged, genesis wins, kind 30078 updated

+# Fix: Local File Persistence & Stall Diagnostic Improvements
+
+## Context
+
+The agent got stuck in a stall loop when trying to create a skill via DM. The root cause is `max_tokens=512` truncating the LLM's tool call JSON. The admin tried to fix it with `/model_set {"max_tokens": 10000}` but got `"failed to persist llm config to config file"` because `model_set` tries to write to a local config file that doesn't exist in the Nostr-native deployment model.
+
+Investigation revealed two tools that incorrectly persist state to local files instead of kind 30078 Nostr events, plus missing diagnostic information in the stall detector.
+
+## Hardcoded File Locations to Remove
+
+### tool_model.c
+- `ctx->cfg->config_path` — references a local config file (genesis.jsonc or config.jsonc)
+- The entire `persist_llm_config()` function (lines 82-139) reads/writes this file
+- The `read_entire_file_local()` helper (lines 42-80) exists only for this purpose
+
+### tool_task.c
+- `"tasks.json"` — hardcoded at line 188: `build_tool_path_local(ctx, "tasks.json", ...)`
+- `tasks_load_root_local()` (lines 82-141) reads from this file
+- `tasks_save_root_local()` (lines 143-159) writes to this file
+
+### tools_schema.c
+- Line 985: `"Update active LLM configuration and persist it to config.jsonc"` — mentions config.jsonc
+- Line 1285: `"Build current task list context block from tasks.json"` — mentions tasks.json
+- Line 1314: `"Manage agent short-term task memory stored in tasks.json"` — mentions tasks.json
+
+## Fixes
+
+### Fix 1: model_set — Persist to Kind 30078
+
+**File:** `src/tools/tool_model.c`
+
+Replace `persist_llm_config()` (lines 82-139) with a function that:
+1. Builds a JSON object with LLM config fields (provider, model, base_url, max_tokens, temperature — NOT api_key for security)
+2. NIP-44 self-encrypts it using the same pattern as `config_store` in `tool_config.c`
+3. Publishes as kind 30078 with tags `["d", "llm_config"]` and `["app", "didactyl"]`
+
+Delete the `read_entire_file_local()` helper (lines 42-80) and the `json_object_set_string()` helper (lines 33-40) — they only exist for the file-based persist.
+
+Also update `execute_model_set()` (line 234) to call the new Nostr-based persist, and return success with a warning if persist fails (since runtime update already succeeded at line 229).
+
+### Fix 2: model_set — Don't Fail When Only Persist Fails
+
+**File:** `src/tools/tool_model.c`, lines 229-236
+
+Currently:
+```c
+if (llm_set_config(&cfg) != 0) {
+    return json_error_local("failed to update runtime llm config");
+}
+ctx->cfg->llm = cfg;
+if (persist_llm_config(ctx, &cfg) != 0) {
+    return json_error_local("failed to persist llm config to config file");
+}
+```
+
+Change to: return success with a `"persist_warning"` field if persist fails, since the runtime update already took effect.
+
+### Fix 3: task_manage — Persist to Kind 30078
+
+**File:** `src/tools/tool_task.c`
+
+Replace `tasks_load_root_local()` and `tasks_save_root_local()` with:
+- `tasks_load_root_nostr()` — queries kind 30078 `d=tasks` from self, NIP-44 decrypts, parses JSON
+- `tasks_save_root_nostr()` — serializes JSON, NIP-44 self-encrypts, publishes kind 30078 `d=tasks`
+
+This follows the exact same pattern as `config_store`/`config_recall` in `tool_config.c` and `memory_save`/`memory_recall` in `tool_memory.c`.
+
+Remove the hardcoded `"tasks.json"` string at line 188 and the `build_tool_path_local()` call for it.
+
+Remove `tasks_path` from the response JSON at line 424.
+
+### Fix 4: Update Schema Descriptions
+
+**File:** `src/tools/tools_schema.c`
+
+- Line 985: Change `"Update active LLM configuration and persist it to config.jsonc"` to `"Update active LLM configuration and persist it to Nostr"`
+- Line 1285: Change `"Build current task list context block from tasks.json"` to `"Build current task list context block from agent task memory"`
+- Line 1314: Change `"Manage agent short-term task memory stored in tasks.json (list/add/update/remove/clear/replace)"` to `"Manage agent short-term task memory stored on Nostr (list/add/update/remove/clear/replace)"`
+
+### Fix 5: Add finish_reason to LLM Response
+
+**File:** `src/llm.h`
+
+Add `char* finish_reason;` to `llm_response_t`:
+```c
+typedef struct {
+    char* content;
+    llm_tool_call_t* tool_calls;
+    int tool_call_count;
+    char* finish_reason;
+} llm_response_t;
+```
+
+**File:** `src/llm.c`
+
+In `parse_llm_response()` (line 276), after extracting `msg` from `choices[0]`, extract `finish_reason`:
+```c
+cJSON* fr = first ? cJSON_GetObjectItemCaseSensitive(first, "finish_reason") : NULL;
+if (fr && cJSON_IsString(fr) && fr->valuestring) {
+    out->finish_reason = strdup(fr->valuestring);
+}
+```
+
+In `llm_response_free()`, add `free(response->finish_reason);`.
+
+### Fix 6: Add max_tokens Truncation Hint to Stall Diagnostic
+
+**File:** `src/agent.c`
+
+In the stall detection block at line 2217, before freeing `resp`, check `finish_reason`:
+```c
+if (repeated_tool_turns >= stall_repeat_threshold) {
+    int truncated = resp.finish_reason && strcmp(resp.finish_reason, "length") == 0;
+    exited_on_stall = 1;
+    llm_response_free(&resp);
+    break;
+}
+```
+
+In `notify_admin_limit_diagnostic()` (line 106), add fields:
+- `possible_cause` — "max_tokens_truncation" when finish_reason was "length"
+- `current_max_tokens` — the current max_tokens value
+- `hint` — "Increase max_tokens: /model_set {\"max_tokens\": 4096}"
+
+**File:** `src/http_api.c`
+
+Same changes in the HTTP API tool loop stall detection at line 966.
+
+## Execution Order
+
+1. Fix 5 (finish_reason in llm_response_t) — no dependencies
+2. Fix 6 (stall diagnostic) — depends on Fix 5
+3. Fix 1 (model_set persist to Nostr) — independent
+4. Fix 2 (model_set graceful failure) — can be done with Fix 1
+5. Fix 3 (task_manage persist to Nostr) — independent
+6. Fix 4 (schema descriptions) — do last, trivial
+
+## Files Modified
+
+- `src/llm.h` — add finish_reason field
+- `src/llm.c` — parse finish_reason, free it
+- `src/agent.c` — stall diagnostic with truncation hint
+- `src/http_api.c` — stall diagnostic with truncation hint
+- `src/tools/tool_model.c` — replace file persist with kind 30078, graceful failure
+- `src/tools/tool_task.c` — replace file I/O with kind 30078
+- `src/tools/tools_schema.c` — update 3 descriptions
