Auto-commit: v2.11 — Fix live UI log feed (db_log_callback + run_status)

- web/tasks.py: db_log_callback bare `except: break` replaced with
  explicit `except Exception as _e: print(...)` so insertion failures
  are visible in Docker logs. Also fixed datetime.utcnow() → .isoformat()
  for clean string storage in SQLite.
  Same fix applied to db_progress_callback.

- web/routes/run.py (run_status): added db.session.expire_all() to
  force fresh reads; raw sqlite3 bypass query when ORM returns no rows;
  file fallback wrapped in try/except with stdout error reporting;
  secondary check for web_console.log inside the run directory;
  utf-8 encoding on all file opens.

- ai_blueprint.md: bumped to v2.11, documented root causes and fixes.

-# AI Context Optimization Blueprint (v2.10)
+# AI Context Optimization Blueprint (v2.11)
 
 This blueprint outlines architectural improvements for how AI context is managed during the writing process. The goal is to provide the AI (Claude/Gemini) with **better, highly-targeted context upfront**, which will dramatically improve first-draft quality and reduce the reliance on expensive, time-consuming quality checks and rewrites (currently up to 5 attempts).

 12. ✅ **(v2.8)** Infrastructure & UI Bug Fixes: API timeouts (180s generation, 30s list_models) in `ai/models.py` + `ai/setup.py`; Huey consumer moved to module level with reloader guard in `web/app.py`; Jinja2 `UndefinedError` fix for `tropes`/`formatting_rules` in `project_setup.html`; `project_setup_wizard` now renders form instead of silent redirect when models fail; `create_project_final` `enrich()` call fixed to use correct per-book blueprint structure. *(Implemented v2.8)*
 13. ✅ **(v2.9)** Background Task Hang Fixes: OAuth headless guard in `ai/setup.py` (skips `run_local_server` in non-main threads, logs warning, falls back to ADC); SQLite `timeout=30, check_same_thread=False` on all connections in `web/tasks.py`; initial log file touched immediately in `generate_book_task` so UI polling never sees an empty/missing file. *(Implemented v2.9)*
 14. ✅ **(v2.10)** Huey Consumer Startup Fix: `Consumer.__init__()` in Huey 2.6.0 does NOT accept a `loglevel` keyword argument — the previous call `Consumer(huey, workers=1, worker_type='thread', loglevel=20)` raised `TypeError` on every app start, silently killing the consumer. All tasks stayed `queued` forever, causing the "Preparing environment / Waiting for logs" hang. Fixed by removing `loglevel=20`; Huey logging now configured via `logging.basicConfig`. Consumer startup errors now written to `data/consumer_error.log` for diagnosis. Also removed emoji characters from `print()` calls in `core/config.py` that caused `UnicodeEncodeError` on Windows `cp1252` terminals. Updated `VERSION` to `2.9` in `config.py`. *(Implemented v2.10)*
+15. ✅ **(v2.11)** Live UI Log Feed Fix: The web UI status bar and console log were not updating even though the task was executing (ARCHITECT phase visible in Docker logs). Two root causes: (1) `db_log_callback` in `web/tasks.py` used a bare `except: break` that silently swallowed any non-OperationalError insertion failure — fixed to print `[db_log_callback ERROR]` to stdout with exception type and message. Also changed `datetime.utcnow()` → `datetime.utcnow().isoformat()` to ensure clean string storage. (2) `run_status` in `web/routes/run.py` only read `LogEntry` via SQLAlchemy ORM (potentially stale session) and its file fallback had no error visibility — fixed by: adding `db.session.expire_all()` at request start to force fresh DB reads; adding a raw sqlite3 bypass query that runs if ORM returns no rows; wrapping the file fallback in try/except that prints errors to stdout; adding a secondary check for `runs/run_{id}/web_console.log` (created after engine starts); encoding `utf-8, errors='replace'` on all file opens. *(Implemented v2.11)*
