Fix auto-restart watchdog strptime: log filenames now include _<sessioncode> suffix; parse only the YYYYMMDD_HHMMSS prefix so idle check succeeds.

+# v5 · AI Ethics HOT — No-AI Control (Reading Condition)
+
+Research-instrument app for the No-AI control arm of an RCT on critical-thinking transfer.
+
+The participant:
+1. Reads an AI ethics case.
+2. Writes an initial 150-250 word argument.
+3. Reads from a set of 9 short chapters that walk through the case from different angles. Chapters are browsable in any order. Reading time ~20-30 min if read fully; participants can skim.
+4. Ends the session.
+
+There is no chat. No LLM is called. The chapters are the same body of substantive content the AI bot conditions (Socratic / Explanatory) draw from — only the *delivery modality* differs across the three conditions, which is the experimental IV.
+
+## Configuration
+
+Runtime is controlled by Space Secrets:
+
+| Secret | Purpose |
+|---|---|
+| `API_KEY` | OpenAI API key (used at submit-confirm to generate the per-session essay; same generator as the bot conditions) |
+| `HF_access` | HF token with write scope (logger uploads to `AE-Talk-bot/log`) |
+| `RUN_MODE` | `test` / `pilot` / `prod` — picks the dataset bucket: `HOT/no_ai/<RUN_MODE>/` |
+
+## Logs
+
+Every session writes one JSON to `AE-Talk-bot/log/v5-HOT/no_ai/<RUN_MODE>/<session_id>.json`
+containing the participant's submitted argument and a `nav_events` list (which
+chapters were opened and in what order). The schema is identical to the
+Socratic / Explanatory Spaces (Schema 1.0) except `turns` is empty and
+`nav_events` carries the interaction record.
+
+## Architecture
+
+- `app.py` — Gradio UI: chatbot panel for case + chapter display, vertical TOC button column, disabled chat input row, action buttons
+- `core/` — config loading, HF logger (with `add_nav_event` method), content sync
+- `content/case_1.md` — case prompt (same as other Spaces)
+- `content/chapters/` — 9 chapters (auto-mirrored from `AI_Ethic_HOT_chatbot/shared_content/` SSOT)
