Follow-up to the traceback gate: client-facing exception detail is now gated too.
- safe_error(e) (app/utils/security.py): returns the exception string only when
FLASK_DEBUG, otherwise a generic message. Full detail stays in server logs.
- All catch-all `except Exception` handlers in api/{graph,report,simulation}.py now
return safe_error(e) instead of str(e); same for the persisted error fields
(project.error / state.error / task fail messages). Typed `except ValueError`
validation handlers (404/400) keep str(e) — those are intentional, actionable
user messages that echo only user-supplied ids.
- graph_builder no longer puts a full traceback into the task error (logs it
server-side with exc_info, surfaces safe_error to the client); the batch-failure
progress message is gated too.
- README documents the CSP connect-src ↔ VITE_API_BASE_URL coupling.

H5 (traceback leak, completing the prior log-level fix): new app/utils/security.py
safe_traceback() logs the full stack server-side and returns it to clients only when
FLASK_DEBUG; all 53 traceback.format_exc() in api/{graph,report,simulation}.py now call
it (import traceback removed).
Upload content sniff: upload_content_ok() magic-byte check — pdf must start %PDF-,
txt/md/markdown rejected if they contain NUL bytes (BOM-prefixed UTF-16/32/8 text
allowed). Wired into the graph.py upload loop so a renamed binary can't pass the
extension whitelist.
Path validation: validate_id() (^[A-Za-z0-9_-]{1,64}$) blocks traversal before every
id->filesystem sink — ProjectManager._get_project_dir, SimulationManager._get_simulation_dir,
ReportManager._get_report_folder + the two Report*Logger __init__, and a new
SimulationRunner._run_dir() that all RUN_STATE_DIR joins route through.
CSP / security headers: CSP <meta> in index.html, vite preview.headers
(X-Frame-Options/nosniff/Referrer-Policy + CSP frame-ancestors), and a Flask
after_request that sets the same headers on API responses.

H1 — stored XSS via v-html / innerHTML of unsanitized LLM/agent/interview/report
content: add DOMPurify; both renderMarkdown() now return DOMPurify.sanitize(html)
(Step4Report.vue, Step5Interaction.vue), and the formatAnswer innerHTML sink is
wrapped in DOMPurify.sanitize. All 8 HTML-injection sinks now sanitized; markdown
rendering preserved (DOMPurify secure defaults keep the md-* tags/classes).
H4 — wildcard CORS: CORS origins now Config.ALLOWED_ORIGINS (comma-separated env,
default localhost:3000) instead of '*'.
H5 — request bodies written to disk in cleartext: logger file level now follows
FLASK_DEBUG (INFO in prod), so the before_request body-debug log is suppressed in
production. (traceback-in-response across 53 handlers deferred to a separate refactor.)

- Add return type annotation (list[str]) to Config.validate()
- Add type annotations (msg: str, -> None) to logger convenience functions
- Add FileParser.is_supported() classmethod for checking file format support
Background threads (graph building, simulation prep, report generation,
profile generation) now inherit the requesting user's locale preference.
Previously these fell back to 'zh' because Flask request context was
unavailable in spawned threads.
- Updated README.md to include new simulation scripts and configuration details for OASIS, including API retry mechanisms and environment variable settings.
- Added simulation management and configuration generation services to streamline the simulation process across Twitter and Reddit platforms.
- Introduced new API routes for simulation-related operations, including entity retrieval and simulation status management.
- Implemented a robust retry mechanism for external API calls to improve system stability.
- Enhanced task management model to include detailed progress tracking.
- Added logging capabilities for action tracking during simulations.
- Included new scripts for running parallel simulations and testing profile formats.
- Updated `run.py` to conditionally print startup information only in the reloader process to avoid duplicate logs in debug mode.
- Modified `__init__.py` to log startup and completion messages based on the reloader process condition.
- Added warnings suppression in `graph_builder.py` for Pydantic v2 regarding Field usage.
- Revised `ontology_generator.py` to enforce strict design guidelines for entity types and relationships, ensuring compliance with new requirements.
- Improved logging behavior in `logger.py` to prevent log propagation to the root logger, avoiding duplicate outputs.
