Pull request overview
This PR splits the monolithic Cloud_Chamber_Cycles.ipynb notebook into two focused notebooks to resolve CI timeout issues. The single-cycle notebook covers sections 1-8 (basic activation-deactivation), while the multi-cycle notebook handles sections 9+ (four-cycle comparisons across three scenarios). Additionally, the PR adds ADW planning documentation for an upcoming activity/equilibria refactor epic.
Changes:
- Split notebook into single-cycle (≤5 min CI) and multi-cycle versions with cleared outputs
- Added cross-references between notebooks via "See Also" links
- Updated simulations index with two separate entries for the new notebooks
- Added ADW dev plans (epic E2 and features E2-F1, E2-F2, E2-F3) for activity/equilibria refactor

The .trash/ directory contains multiple temporary utility scripts and test files that should not be included in the PR. These files appear to be development/debugging artifacts (tmp_wall_fix.py, tmp_split_notebooks.py, tmp_json_check.py, etc.) and the old combined notebook. Please remove all .trash/ directory contents from this PR before merging.

The single-cycle notebook uses "par.gas.AtmosphereBuilder()" but according to the PR description, the notebook fails because "AtmosphereBuilder lacks set_total_pressure". The correct import path appears to be "par.AtmosphereBuilder()" based on line 181 of the actual notebook code. However, this inconsistency should be verified - if the API has changed, ensure all references use the correct import path.

Update cloud chamber simulation with more realistic particle sampling and improved condensation strategy: - Use lognormal sample distribution for particle radii (1000 particles) - Switch to CondensationIsothermalStaggeredBuilder with random theta mode - Adjust simulation timing (30s phases, 0.1s timestep) for better resolution - Add 2-panel plot showing particle diameters and gas-phase RH evolution - Track gas-phase water concentration throughout simulation - Improve comments and documentation clarity - Fix unicode dash characters in markdown - Remove trailing cell expressions and clean up code style
Apply corrections from Cloud_Chamber_Single_Cycle.ipynb to ensure consistency and fix simulation bugs. Key changes: - Add saturation water vapor concentration using Buck equation - Add humid/dry phase water concentrations (c_water_humid, c_water_dry) - Add shared wall loss strategy setup for all scenarios - Change run_cycle parameters from rh_humid/rh_dry to actual concentrations - Fix water concentration setting at phase transitions - Use get_lognormal_sample_distribution() for particle sampling (100 particles) - Calculate mass from volume and density properly - Create separate condensation strategies with matching molar mass arrays - Add missing simulation runs (run_multi_cycle() for all scenarios) - Fix visualization and validation cells for new particle counts - Fix mass accounting validation (total mass can increase due to water uptake) Both notebooks now pass validation.
Replace the single "Cloud Chamber Cycles" entry in the Examples index with two separate entries: - Cloud Chamber Single Cycle: Single activation-deactivation cycle demonstrating basics of cloud droplet activation with κ-theory hygroscopicity - Cloud Chamber Multi Cycle: Four-cycle simulation comparing three seed scenarios (AS, sucrose, mixed) with κ-dependent activation analysis Update both docs/Examples/index.md and docs/Examples/Simulations/index.md to reflect the notebook split.
Condense the Cloud Chamber Single Cycle and Multi Cycle descriptions to match the concise style of other End-to-End Simulation entries in the examples index.

491230e6Summary
Split the monolithic
Cloud_Chamber_Cycles.ipynbinto two focused notebooks, one that covers the single activation–deactivation cycle (sections 1‑8) and another that keeps the multi‑cycle comparison (sections 9+). Added clear introductions/learning objectives, cross ‘‘See Also’’ links, and updated the simulations index entry to point to the two new notebooks. The original combined notebook is removed to avoid CI timeouts, and the supporting ADW planning docs capture the new feature/equilibria refactor roadmap.What Changed
New Components
docs/Examples/Simulations/Notebooks/Cloud_Chamber_Single_Cycle.ipynb- retains sections 1‑8 with a new intro, learning objectives, and a link to the multi‑cycle companion; outputs cleared so it fits within the 5‑minute CI limit.docs/Examples/Simulations/Notebooks/Cloud_Chamber_Multi_Cycle.ipynb- carries sections 9+ plus the multi‑scenario helpers and plots, with its own intro and link back to the single cycle notebook.adw-docs/dev-plans/epics/E2-activity-equilibria-refactor.mdandadw-docs/dev-plans/features/E2-F1-activity-strategy-refactor.md/, E2-F2-equilibria-runnable-refactor.md- added planning documentation for the refactor epic and its two immediate features to keep the maintenance runway aligned with the notebook updates.Modified Components
docs/Examples/Simulations/index.md- replaced the single entry with two catalog entries for the new notebooks, including descriptive blurbs and reciprocal "See Also" links.docs/Examples/Simulations/Notebooks/Cloud_Chamber_Cycles.ipynb- removed as part of the split so CI only touches the targeted notebooks.Tests Added/Updated
run_notebook({notebookPath: "docs/Examples/Simulations/Notebooks/Cloud_Chamber_Single_Cycle.ipynb", timeout: 300})(fails: AtmosphereBuilder lacksset_total_pressure, so the notebook stops during the setup block before Atmosphere is built; needs builder API adjustment before rerun).How It Works
The split keeps all shared configuration at the top of each notebook but limits the single-cycle notebook to sections 1‑8 so that it completes within the CI timeout. The multi-cycle notebook resumes from
# Part 2and focuses on comparing the four-cycle scenarios, reusing the same builders but with an explicit prerequisite note linking back to the single-cycle walkthrough. The simulations index now surfaces both notebooks, making it obvious to users which tutorial suits their needs.Implementation Notes
AtmosphereBuilderno longer exposesset_total_pressure; once the builder API is restored/updated, rerunning the notebook should succeed, and the multi-cycle validation can follow.Testing
