EF 3.1	Emissions → Emissions to air → Emissions to air, unspecified (long-term)	Environmental → Air → Long-term envi-air-lote	Was envi-air-grle-ru10pesq, which mismapped 7,277 flows onto a ground-level rural context and collided with `Emissions to non-urban air close to ground`. EF gives this flow different factors from `Emissions to air, unspecified` for 6,591 of the 7,284 substances they share, so it cannot be folded onto envi-air-unkn either; the long-term strata value added in cauldron/brightway#3012 is what makes a correct mapping expressible.

EF 3.1	Emissions → Emissions to air → Emissions to non-urban air or from high stacks	Environmental → Air → Medium stack, <150 meters → Rural (<1000 people/square mile) envi-air-mest15me-ru10pesq	`non-urban air or from high stacks` names two situations at once -- a release in the countryside, or a release from a tall stack anywhere -- and no context can hold both. It was published as envi-air-hist15me, which says a dairy barn's ammonia left a 150-metre chimney; the other reading, Ground level + Rural, says a power-station plume was released at head height, and nothing in a flow says which it is. EF 3.1's factors settle it, and they pick neither: in all 40 (flow, method) pairs where this compartment and one of EF's narrow non-urban compartments are both characterised, EF gives this one exactly the factor it gives `Emissions to non-urban air high stack` -- particles (PM2.5) 3.01757e-06, against 1.13763e-05 non-urban close to ground and 1.62949e-06 non-urban very high stack. That compartment is envi-air-mest15me-ru10pesq here, so this keeps the rural qualifier the compartment does assert and takes the stack height EF characterises rather than the one the name suggests. What is given up: a release that really did leave a >150-metre stack is published as a sub-150-metre one, which EF's own numbers say is the smaller error. Decided once for the three lists that spell this compartment differently -- EF 3.1, ecoinvent in all five versions, and BAFU's `emissions to air / low. pop.`, SimaPro's spelling of ecoinvent v2's `low population density` -- because moving one alone would split them apart. (#411) EF alone also ships the narrow `Emissions to non-urban air high stack` (16 flows), which maps here as well; the two collapse, and since EF gives them the same factor in every pair that has one, no characterisation is lost.
EF 3.1	Emissions → Emissions to air → Emissions to non-urban air very high stack	Environmental → Air → High stack, >150 meters → Rural (<1000 people/square mile) envi-air-hist15me-ru10pesq	Was envi-air-hist15me, which had no population density and so collapsed this onto the urban very-high-stack flow and the legacy `non-urban air or from high stacks`. EF characterises the distinction: particles (PM2.5) is 1.62949e-06 here against 3.41614e-05 urban, and the survivor was decided by UUID sort order (cauldron/brightway#3012).

EF 3.1	Emissions → Emissions to air → Emissions to urban air very high stack	Environmental → Air → High stack, >150 meters → Urban (>1000 people/square mile) envi-air-hist15me-ur10pesq	Was envi-air-hist15me; see the non-urban very-high-stack row. This is the arm of the pair that carried the higher factors.

EF 3.1	Emissions → Emissions to soil → Emissions to non-agricultural soil	Environmental → Ground → Non-agricultural envi-grou-noag	Was envi-grou-unkn, shared with `Emissions to soil, unspecified`; the collapse discarded 11,824 CF values and left ecoinvent's `soil / unspecified` inheriting whichever factor won on UUID sort order, the two differing by up to 30x. envi-grou-noag is deprecated on arrival (cauldron/brightway#3012): it exists to separate these two EF contexts, not as a land cover class to map onto.

EF 3.1	Emissions → Emissions to water → Emissions to water, unspecified (long-term)	Environmental → Water → Long-term envi-wate-lote	Was envi-wate-unkn, the same IRI as `Emissions to water, unspecified`, so EF's 7,186 long-term water flows collapsed onto the short-term ones under deduplication. That collapse is what stranded ecoinvent's `water / ground-, long-term`: its correspondence table points 260 of 269 rows at EF's own long-term flow, and following the deprecation redirect landed them back on unspecified water, where 180 of them received a short-term factor for a release ecoinvent defines as >100 years out. This is the same move #272 made for `Emissions to air, unspecified (long-term)`, and for the same reason -- both sides of a temporal pair have to meet in the temporal context or neither does. The previous comment read `Temporal differentiation belongs to LCIA, not LCI`, which was decided before ecoinvent's row moved; #274 is where the combination was weighed. It costs ~7,156 uncharacterised identifiers: only 30 of the 7,186 carry any EF 3.1 factor, so almost nothing is recovered by publishing them, and what is bought is that no flow silently inherits a factor from a different compartment.
