The Mercury app (3.2.x) is a hybrid server whose kernel pool serves both
the client-facing app view and JupyterLab, so the server-level
MERCURY_CONFIG_DIR signal cannot tell who is looking and leaks backstage
content in the app. Switch the primary stage signal to the shadow-copy
session name (__mercury__ in JPY_SESSION_NAME), keeping the env var only
as a --working-dir fallback.
- Update CX Discovery staging.py to the per-view detection model
- Ignore Mercury runtime artifacts (.mercury_sessions/, *__mercury__*)
- Document the leak in remaining masters (TEI, CTM, AI Diagnostic,
template) and flag the staging.py retrofit as urgent
Add CLAUDE.md defining the Palladium master notebook conventions and
Red Panda Approval criteria, plus a review-notebook slash command for
LLM-driven notebook review.
Expand .gitignore to block client/engagement documents and generated
exports, keeping masters client-clean while allowing text/image sources.
Normalize slider widget numeric values from floats to integers in
notebook JSON.
Reorganize Palladium codebase into a modular architecture with `core/`
shared logic and `app/` Streamlit UI, separating per-study assets into
`studies/YYYYMM_<Vendor>/` folders containing notebooks, seed data, and
configuration. Update README to reflect new structure, add `.gitignore`
entries for `.env` and study exports, and refresh component documentation.
