Notes on 2025-05-21 PMF. Picked back up after the last review.
Related: 2026-09-21 review, 2025-05-21 ship.
Cross-section thread: internal SLA 8447. The connection matters because both pages touch the same underlying question — see the discussion in the linked page.
- Learning → cohort → fine-tune. Worth a second pass; the learning angle keeps coming back.
- Delaware → tool → ship. Worth a second pass; the delaware angle keeps coming back.
- Second-brain → mission → retrieval. Worth a second pass; the second-brain angle keeps coming back.
- Gtm → inference → SLO. Worth a second pass; the GTM angle keeps coming back.
Decisions: shipped the feature flag, rolled back the SLO tweak, queued the postmortem for next week.
