Request

I'm assembling our 2028 investigation-framework refresher. Create a short standalone checkpoint annotation for the February 20 H2 historical same-week comparison. Include the comparison values, continuity with the earlier cohort method, the direction of the evidence, and the validation item that was still outstanding. Frame it strictly as the pre-ruling checkpoint rather than as a final H2 conclusion.

Required memory

Fact 321

On February 20, 2023, Riley Tanaka used the same cohort logic as the January scan and Owen check for an H2 same-week comparison: mid-segment monthly churn was 2.2% in February 2022 and 2.0% in February 2021, showing no apparent historical counterpart to the current spike.

pulled the same-week comp for h2. Feb 2022 mid-seg monthly churn is 2.2%. Feb 2021 is 2.0%. so unless i've broken the cut in some new fun way, there just isn't a historical version of this spike sitting there. using the same cohort logic as the Jan scan + the Owen check this morning. h1 already looked dead after the tier split came back flat, and this pushes pretty hard against the easy "seasonal" / competitor-cycle story too. still want to sanity check denominator handling once more before i say that too loudly -- but directionally this is bad for the comforting explanations. Marcus is still trying to run the pricing-page thing in parallel lol

Fact 322

Riley Tanaka considers the historical comparison directional evidence against a seasonal or competitor-cycle explanation, but wants one more denominator-handling sanity check before stating that conclusion strongly.

Fact 323

On February 21, 2023, Riley Tanaka ruled out H2—competitor cycle or a generic seasonal effect—as an explanation for the mid-segment churn spike because historical February comparisons showed no matching spike.

H2 is out. Pulled the historical Feb comps with the same cohort logic as the Jan scan + Owen's check this morning, and 2021 / 2022 are both basically boring: 2.0-2.2% churn, no matching spike at all. So I'm not buying competitor-cycle or some generic seasonal thing here. Owen's drafting the 1-pager now. That's two down, two left on the board: H3 onboarding-timing, H4 CS coverage. Marcus can keep waving the pricing-page experiment around if he wants, but it doesn't explain this cut.
