03 Chvi Phase Partition Sigu

03 — ChvI regulon phase partition + putative SigU regulon¶

Purpose¶

Pre-registered H1 phase-structure threshold (RESEARCH_PLAN v2)¶

A note on SigU¶

1. Build DEG sets at consistent thresholds (FDR<0.05, |logFC|>1)¶

2. Normalize ChvI reference sets to CCNA tags¶

3. Phase partition (early/cooperator vs late/consequence)¶

4. Functional annotation enrichment per cohort¶

5. Show the actual gene lists per cohort¶

6. Putative SigU regulon — empirical definition + characterization¶

7. Cross-check: does the late cohort show coherent regulatory signal?¶

8. Apply pre-registered H1 verdict¶

9. Provenance: SigU literature gap¶
