Latest summary
Closed the BG marginal/source evidence pass with official NSI Census 2021 and timeseries source inventory, hidden-population/assignment gap flags, downloader queue, and manager update. Reports written under /home/synthestat/workspace/manager_handoffs/marginals/, with EVIDENCE_EXHAUSTED explicitly marked for homelessness, institutional residents, undocumented/seasonal workers, address-level dwelling registers, and deterministic assignment rosters/catchments.
Body
Reviewer verdict for BG cycle 1 is NEEDS_MORE_SOURCES. Concrete marginal/source questions to close before a PASS-capable rerun:
Context:
- Bundle reviewed: /home/synthestat/output/runs/BG/bg_population_review_cycle1_85123614_seed420987
- Current bundle is contract-complete but only 8 persons/8 households across 2 seeded naseleno-myasto-style test zones.
- Live NSI retrieval adapter is not implemented in the promoted path; source_provenance entries lack source_url/retrieval_timestamp/reference_period/licence/checksum at entry level.
Questions / acceptance criteria:
1. Find official Bulgaria NSI or authoritative endpoints/tables for age x sex x settlement/municipality/NUTS3 where available, household counts/type/size by settlement/municipality/region, education by age/sex/region, employment/industry/occupation by age/sex/education/region, and income by region/household/person type.
2. Find official or legally usable building/dwelling/address stock sources sufficient to replace AGCC-style seeded fixtures and heuristic dwelling inference, or document why unavailable.
3. Find hidden-population marginal sources with uncertainty or documented coverage: homelessness, institutional/group quarters, asylum/refugee populations, Ukrainian temporary protection/displaced persons, Syrian refugees if separable, students/institutional locations, undocumented/seasonal workers if any official/survey basis exists.
4. Find school/work/facility assignment marginals: school register/capacity/catchment or attendance by residence, workplace/commuting flows, facility rosters/capacities where legally usable.
5. Return concrete source IDs/URLs/table IDs/API endpoints, retrieval notes, reference periods, licences, and quality flags so synth-downloader can freeze/catalogue them before modeler use.
Do not invent proxy precision. If a source cannot be found after reasonable search, document the search path and mark unavailable for human decision.
