split: calibration

context_text: Location: Yahotyn, Kyiv Oblast, Ukraine. Event/context: Yahotyn logistics center strike aftermath (2022). Date window: 2025-08-31T09:06:35Z to 2026-03-14T08:56:26Z. Modality: optical-to-optical.

source_dataset: Blackline Atlas Sentinel-2 paired capture

country: Ukraine

location_name: Yahotyn, Kyiv Oblast

modality: optical-to-optical

visibility_quality: good

label_method: manual Blackline Atlas scenario label converted to reporter JSON

visible_change_summary: The current image shows warehouse/logistics-facility scarring compared with the baseline.

uncertainty_factors: Single-pair Sentinel-2 evidence should be reviewed against higher-resolution imagery.

severity_hint: high

short_rationale: Visible civilian logistics disruption is plausible but retained for calibration rather than training.

country: Iraq

location_name: Baghdad

visible_change_summary: The aid warehouse compound remains materially stable between the baseline and current images.

uncertainty_factors: Calibration hard negative; no visible damage despite aid/logistics context.

recommended_action: discard

short_rationale: No defensible damage or disruption signature is visible on the exact aid parcel.

context_text: Location: Marinka, Ukraine. Event/context: Russian invasion of Ukraine — Marinka civilian building damage. Date window: pre-2022 conflict baseline to post-2022 conflict damage imagery. Modality: optical-to-optical.

source_dataset: xBD-Ukraine local materialization from sda-kr/xbd-ukraine lineage

location_name: Marinka

baseline_date: pre-2022 conflict baseline

current_date: post-2022 conflict damage imagery

label_method: xBD/xView2-style building-damage labels aggregated to paired-image reporter JSON

visible_change_summary: Post-event imagery for Marinka contains multiple major/destroyed building labels consistent with visible civilian building disruption.

uncertainty_factors: xBD-Ukraine labels are building-level annotations aggregated to a tile-level reporter target.

uncertainty_factors: This row should not be used for tactical localization or individual-building targeting.

short_rationale: Aggregated xBD-style labels indicate strong building damage in a civilian urban tile; recommend immediate analyst review. Building label counts: {'major-damage': 13, 'no-damage': 34, 'destroyed': 27, 'minor-damage': 9}.
