Upgrade to segment-targeted net-benefit model + Retail/DMS view - #1
Merged
Conversation
Replace the dealer-lot prototype with the national-portfolio analysis: - App.tsx: rescale to national OEM pipeline ($2.87B deployed); add segment-specific DSI targets, a net-benefit decision engine (act only when carrying cost avoided > clearance loss), strict typing, and a new Retail & DMS view drilling the thesis to dealer floorplan economics. - README.md: answer-first rewrite with defensible-metrics framing. - METHODOLOGY.md: new — full formulas, assumptions, sensitivity, limits. Verified: tsc --noEmit clean, vite build succeeds. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- Dashboard: the per-row Reallocate action now obeys the same net-benefit gate as "Execute all" — when clearing a pool costs more than the carrying cost it avoids (netFirstYear <= 0), the row shows a "Hold · net-negative" state instead of an actionable button, and executeOne guards against acting. Previously a single row could be cleared against the model's own act-only-when-it-pays rule (e.g. at an 8% carrying rate). Matches METHODOLOGY.md §5/§8. - CI: add a `tsc --noEmit` typecheck gate before build. - Deploy: guard the GitHub Pages publish to push-to-main only, so pull_request builds no longer risk publishing un-merged code.
