New-Nature Density Collective (LM-Dawn class)

Class card for LM-Dawn collective forms that re-establish biotic density within extant MM/DM built infrastructure — urban rewilding, green-roof retrofitting, stream daylighting, urban beehives, civic mycelium-substrate construction, building-integrated agriculture, and biodiverse corridor stitching through asphalt-and-concrete urban fabric. The Wave-0 LM signature "new nature density" / "moss/mussel reclamation" names this class: the insurgent ecological re-occupation of built environments that the Modernity Machine constructed as sealed, sanitized, biota-excluded surfaces. Distinguishing features versus sibling LM cards: (1) operates WITHIN extant MM/DM built infrastructure, not at wildscape scale (distinct from machine:bioregional-rewilding-2020); (2) the governance unit is the urban collective, neighbourhood association, building retrofit consortium, or civic-biodiverse-corridor partnership — not the watershed co-governance board (distinct from machine:water-stewardship-watershed-class); (3) productivity of built environment is maintained or increased alongside biotic density (distinct from pure rewilding). The machine's unifying operational grammar: collective actors retrofit MM/DM built-environment substrates (rooftops, stream-channels culverted underground, vacant lots, street corridors, construction materials) to host living ecological function — pollinators, stormwater infiltration, mycelial networks, food-producing plants, nesting birds, and moss/lichen colonizers. Named [EXTRAP] instances: High Line NYC (abandoned elevated railway converted to biodiverse linear park, 2009+; 500+ plant species, 40+ bird species by 2024); Seoul Cheonggyecheon stream daylighting (2005; 5.8 km of culverted urban stream surfaced; ecological communities re-established; urban heat reduction measurable); London Sustainable Urban Drainage Action Plan + urban rewilding networks (Rewilding Britain urban pilot; London National Park City designation 2019); Singapore Park Connector Network + Gardens by the Bay biotic-density grid (350 km of green corridors; >3M visitor-ecosystem-contact events/yr); Toronto Green Roof Bylaw 2009 (~600 buildings; largest mandatory green- roof policy globally 2009); Detroit urban-farms-on-vacant-lots (Earthworks Urban Farm, Keep Growing Detroit, ~1,500 plots on post-industrial vacant lots); Berlin Tempelhofer Feld (natural succession on former airfield; ~386 ha of urban rewilding under community stewardship); Eindhoven Stratumseind smart-greening corridor; Beirut Garden of Coexistence (civic rewilding post-conflict); mycelium-brick prototypes (MycoWorks, Ecovative — structural construction materials grown from mycelium on agricultural waste; carbon-negative; biotic substrate embedded in architecture). Motor is null per LM invariant (§12.1.2; Wave 0 Q2). Coordination emerges from multi-species feedback (pollinators establishing corridors, mycelial networks self-expanding, birdlife responding to habitat nodes), collective governance grammar (green-roof bylaws, park connector planning frameworks, community land stewardship agreements), and biophilic-design practitioner networks — not from MM Progress telos of maximum throughput. LM mechanism signatures: new_nature_density HIGH (this class is the primary producer of new_nature_density signal INSIDE urban built environments); capture_resistance_index MEDIUM (urban green infrastructure is perpetually at risk of corporate greenwashing capture — "biophilic office tower" branding vs. genuine habitat corridor stitching); proletarianization_risk MEDIUM-LOW (requires living horticultural, mycological, and ecological design competence that is not fully inscribable into technical artefacts); liveness_temporal_coupling HIGH (pollinators operate on real-time ecological clocks; mycelial networks grow on biological time; stormwater infiltration is event-driven). [STUB-commodity-gap]: Commodity enum lacks green-roofs-installed-count, biotic-density-units, hectares-greened, urban-beehives-installed, mycelium-bricks-produced — all Throughput quantities set to null + [STUB]. [STUB-substrate-enum-gap]: institutional substrate not in SubstrateType enum; using [animate, social, corporeal] triple + note.
