Latest summary
Built and verified the LT cycle-1 population review bundle at /home/synthestat/output/runs/LT/lt_population_review_cycle1_813e5acd_seed420987. The bundle is contract-complete for internal review, HARD residuals pass exactly, and hidden-population/work-school layers are explicit unavailable markers rather than fabricated estimates.
Body
Build the cycle-1 Synthestat population review bundle for country LT (Lithuania). Project root: /home/synthestat Target geography: finest available official geography that current evidence/code can support. Release mode: internal research review. Contract to follow exactly: /home/synthestat/docs/contracts/population_review_bundle.md Output convention: /home/synthestat/output/runs/LT/<run_id>/ Also write a short handoff under /home/synthestat/workspace/manager_handoffs/modeller/ with the run_id, bundle path, exact limitations, missing sources, degraded zones, and validation command/results. Goal: Create the best current 1:1 LT synthetic population candidate that the existing Synthestat algorithms and available registered/seeded sources support: persons in households, households in dwellings, dwellings in real houses/buildings where available. Include hidden/weakly measured overlays only where evidence supports them and keep them separate from de jure HARD constraints. Non-negotiables: - Reuse existing Synthestat modules/algorithms; do not fork country-specific synthesis logic. - HARD constraints must not break. If a required HARD source is missing, emit an explicit unavailable/degraded marker instead of inventing precision. - Every model-based estimate needs uncertainty bounds or must be flagged invalid/unavailable. - Hidden-population overlays (homelessness, refugees/asylum seekers, Ukrainian displaced people, Syrian refugees, undocumented/seasonal populations, students, institutional populations) must not silently rewrite official de jure constraints. - Finest-geography occupation/industry/work-school/building assignments are model-driven unless measured; flag this explicitly with quality tiers and provenance. - Log every missing source, failed download, relaxed constraint, degraded zone, unavailable layer, reference period, source ID, retrieval timestamp, and quality flag. Required bundle files are listed in the contract. If a layer cannot be responsibly produced, write the required unavailable.json with reason, evidence status, and proposed next source/model improvement. Definition of done: - Bundle directory exists and is contract-complete. - build_manifest.json contains all minimum manifest fields from the contract. - constraint_residuals.json proves HARD residuals are exact or explicitly explains why no valid output exists. - uncertainty_summary.json and source_provenance.json exist and are not empty. - model_notes.md honestly separates measured/constrained/modelled/unknown claims. - Handoff names exactly what the reviewer should inspect first.
