EVT 2026-02-20 - Stage F KPI Operational Contract and Governance Autocomplete

Session scope

Continue autonomous product exploration and close the execution gap between KPI definition and KPI operation, so long-term product decisions stay consistent and measurable.

Confirmed outcomes (auto-recommended defaults)

1. KPI operation cadence:

• Daily monitoring (D-1 snapshot),
• Weekly product review,
• Monthly policy review and adjustment.

2. KPI denominator/eligibility normalization:

• habit_retention: rolling 4-week cohort based on valid completed-day signals.
• recommendation_to_attempt_rate: only count recommendation items that were actually rendered and visible.
• locked_feature_upgrade_conversion: evaluate from locked-entry exposure to checkout success within attribution window.

3. Guardrail thresholds (default):

• habit_retention drop >5pp WoW -> investigation trigger.
• recommendation_to_attempt_rate drop >8pp WoW -> recommendation audit trigger.
• locked_feature_upgrade_conversion drop >10pp WoW -> offer/paywall audit trigger.

4. Escalation rule:

• 1 week breach: diagnosis note.
• 2 consecutive weeks: open experiment ticket.
• 3 consecutive weeks: mandatory policy review (DEC update candidate).

5. Segmentation baseline:

• Mandatory KPI cuts by program, tier, and cold_start_vs_returning.

Open items carried forward

• None for this KPI governance refinement batch.
