Migration

Goal

Move the current cost-of-substitution implementation into renunney in staged, low-risk steps.

Current State

Operational code still lives in:

• ../../collaborations/to_ptbc/evc/cost_of_substitution

renunney currently acts as:

• a clean git repository,
• a run-control wrapper,
• a stable place for deployment and orchestration commands,
• the eventual destination for migrated code.

Recommended Migration Order

1. Orchestration control plane has been migrated locally:
   • src/renunney/orchestration.py
   • scripts/run_orchestration.py
2. Paper-scale Figure 1 submission configs have been copied locally into config/.
3. Track 1 runner and API boundary have been migrated locally:
   • scripts/run_track1.py
   • src/renunney/track1_api.py
4. Track 1 analysis boundary has been migrated locally:
   • src/renunney/track1_analysis.py
5. Track 1 threshold/search boundary has been migrated locally:
   • src/renunney/track1_threshold.py
6. Track 1 simulation kernel has been migrated locally:
   • src/renunney/track1_reference.py
7. Track 1 report layer has been migrated locally:
   • src/renunney/track1_report.py
8. Track 1 extinction-model data layer has been migrated locally:
   • src/renunney/track1_extinction.py
9. Track 1 dataset generator has been migrated locally:
   • src/renunney/track1_dataset.py
10. Migrate the fit module next:

• python/track1_fit.py

11. Reduce or remove the remaining compatibility-layer imports after those modules are local.
12. Migrate docs and example configs last, after path references are updated.

Constraint

Do not break the ability to run current Figure 1 jobs while migrating code.
