| TSG formula | ✅ Real | src/lib/tsg.ts | Tested: D=S=0 → undefined (null), only D → +1, only S → −1 |
| Services (S) | ✅ Real, OSM | src/data/osm/services.json | 575 places, extracted 2026-11-05 via an Overpass mirror; OSM snapshot date 2026-06-01 (the mirror lags). OSM coverage is incomplete. Re-run npm run osm:fetch. |
| People present (D, dynamic) | ⏳ No real data yet | admin import → observations table | Imported via /admin CSV. Until then the map shows demo data. |
| Demo points + counts | ⚠️ DEMO, synthetic | src/data/demo/demo-data.ts | 10 arbitrary locations, invented numbers. Always shown with a "DEMO DATA" banner and badges. Never mixed with real data. |
| Residents (D, static) | ⚠️ PLACEHOLDER | src/data/population.ts | All null for real points → static mode shows "population not provided". Demo points have demo population. |
| Detector accuracy | ⚠️ Not verified | methodology page | YOLOv8n counts not yet manually checked. |
| Validation (holdout, block CV, survey) | 📝 Plan only | methodology page | No results yet. |
| Feedback, analytics, waitlist | ✅ Real (stored) | Supabase or .data/ locally | No personal data except waitlist email with consent. |
| City analysis | | | |
| City boundary | ✅ Real, OSM | public/data/taldykorgan/boundary.json | OSM relation 3392135 (city akimat, admin_level 6) — includes surrounding settlements. |
| Walk network | ✅ Real, OSM | roads.json, src/data/city/graph.json | 5 867 walkable ways, ~2 055 km, largest connected component (OSM snapshot 2026-11-05). Street centrelines, sidewalks rarely mapped. |
| Facilities (6 categories) | ✅ Real, OSM | facilities.json | 585 objects; tag rules in scripts/build-city.mjs and src/lib/city/types.ts. OSM is incomplete (e.g. only 44 pharmacies) → gaps are overstated. |
| Residents | ✅ Real, WorldPop | grid.json | WorldPop Global2 R2025A constrained 100 m, 2021 (CC BY 4.0): 176 584 people in the boundary, summed into 2 475 cells of 250 m. A model, not a count. |
| Census 2021 total | ⏳ Not loaded | model settings | Optional proportional rescaling once you enter the verified figure. |
| Presence by time of day | ✅ Agent model (default) | data/agent-model/, agent-presence.json | The author's agent-based model (≈17 k agents, 100 runs) laid onto the 250 m grid (npm run city:agent). Users can switch to their own assumptions (src/lib/city/model.ts). Video check (H2) not confirmed yet — see research/H2_REPORT.md. |
| Walking access | ✅ Computed | access.json | Dijkstra on the walk network, ≤1 200 m, from cell centres. |
| Service Gap Index | ✅ Computed | src/lib/city/gap.ts | TSG formula on city-wide shares; tested. |
| Location assessment | ✅ Rule-based | src/lib/city/location.ts, /api/location | Explainable comparisons with numbers; no revenue prediction. |
| Kazakh translation | ⚠️ Draft | src/i18n/kk.ts | Needs review by a native speaker. |
| Payments | ❌ Not built (by design) | — | Freemium is a test: "Pro" gate + waitlist + click counting + free preview. |
