Lifecycle Ops (Stage 8)
Closes the loop from one-off validation to ongoing operation. Read dossier-schema.md if needed.
Write into lifecycle. Do not render.
Procedure
- Funnel metrics — the operating metrics to watch (from the AARRR funnel if stage 7 ran).
- Cohort retention — how retention is tracked; retention is the truth serum for product-market fit.
- Expand / sunset criteria — explicit numeric thresholds for scaling up vs winding down. Decide these now, while unattached, so the later call isn't driven by sunk cost.
- Re-validation loop — set
lifecycle.revalidation: thetrigger(time- or event-based) andstages_to_recheck. Seed it fromdecision.journal.reversal_conditions— those tripwires are exactly what should re-open earlier gates.
Writes
lifecycle.* and a stages[] record (stage_id: 8).
