Spatial
Ground
The canonical architectural home of BitPangea World-space membership.
Spatial Ground canonically expresses and preserves which canonical Survey space is BitPangea World-space. It is the Atlas domain that adds canonical World membership to the reference and mathematics supplied by the Foundational Survey Fabric while remaining deliberately silent about the higher meanings built above that membership.
Spatial Ground does not create The World, redefine constitutional truth, or duplicate the Survey Fabric. Constitutional reality constrains the domain; the Creator designs the exact permissible spatial expression where the Constitution leaves room; a recorded Atlas adoption act makes one definition canonical; and Spatial Ground thereafter preserves that adopted World-space for every higher layer that depends upon it.
Atlas Working Principle The Foundational Survey Fabric supplies canonical spatial reference and mathematics. Spatial Ground adds canonical participation in The World.
Standing
Structural Domain
Spatial Ground is the Atlas domain that canonically expresses and preserves World membership over canonical Survey space. It consumes reference and spatial mathematics from the Foundational Survey Fabric and provides stable membership truth upon which higher spatial interpretation may depend.
Status
The Spatial Ground Requirements are adopted, SG-SPEC-1.0 is adopted, Gate B is complete, and SG-WORLD-SPACE-INSTANCE-0001 is the adopted canonical World-space instance. Production Conformance and independent reconstruction have passed with zero cross-implementation mismatch.
Authority
Constitutional truth constrains. The Creator designs within what remains open. A recorded Atlas Adoption Act makes a permissible definition canonical. Spatial Ground then preserves that adopted World-space without acquiring authority to redefine constitutional truth.
Governing Framework
Spatial Ground is organized through four institutional framework layers. Each has a distinct role: Requirements state what must remain true; Specification defines the formal semantics and production rules; Conformance proves implementation compatibility; and Reference Vectors demonstrate the Specification through exact executable cases.
Requirements
States the governing obligations Spatial Ground must preserve, including exact membership, constitutional subordination, layer boundaries, permanence, and the FSF dependency contract.
Framework 02Specification
Defines the Canonical Membership Predicate Model, SG-CJSON 1.0, canonical evaluation semantics, the FSF dependency surface, and the adopted production profile under SG-SPEC-1.0.
Framework 03Conformance
Defines how independent implementations prove that they correctly follow SG-SPEC-1.0 without becoming a source of canonical World-space authority.
Framework 04Reference Vectors
Provides exact executable fixtures and expected results that demonstrate SG-SPEC-1.0. Reference Vectors test the Specification; they do not create it.
Architectural Sequence Requirements state what must be satisfied. Specification defines how Spatial Ground works. Conformance proves implementation compatibility. Reference Vectors demonstrate the Specification. None of the downstream proof layers may create missing Specification mathematics or canonical authority.
Canonical Instance and Institutional Records
The four-framework architecture governs Spatial Ground semantics and proof. Separate institutional records establish canonical status, preserve the adopted production instance, and retain the architectural review and governance history without becoming alternate sources of membership truth.
Requirements Adoption Act
SG-ACT-REQ-2026-0001 records the act that placed the Spatial Ground Requirements into the Adopted state and completed Gate A.
GovernanceInstance Adoption Act
SG-ACT-INSTANCE-2026-0001 establishes SG-WORLD-SPACE-INSTANCE-0001 as the singular canonical World-space instance.
Canonical InstanceProduction Ground Definition
The adopted one-root SG-CJSON 1.0 Ground Definition that references the canonical FSF World SCPE and expresses canonical World membership.
Production ProofConformance / Reconstruction Proof
The final production proof recording PASS across two independent reconstruction implementations with zero cross-implementation mismatch.
Purpose and Boundary
Spatial Ground exists so that every valid Survey location can receive one exact canonical answer to the question of participation in The World. The answer is total, two-valued, deterministic, independent of later interpretation, and permanent once the canonical World-space instance is adopted.
The domain owns World-membership meaning and nothing beyond it. It does not determine Parcel identity or eligibility, terrain, visual World Form, Regions, Clusters, ownership, rights, settlement, construction, economics, culture, experience, or any other higher-layer interpretation. Those systems may depend on Spatial Ground, but they may not complete, modify, or replace its membership truth.
Architectural Boundary Spatial Ground answers whether canonical Survey space participates in The World. Higher layers determine what that World-space means.
Atlas Working Principle Chronicle records when. Atlas records what.
Demonstrated dependency: Foundational Survey Fabric → Spatial Ground → General Spatial Interpretation. FSF-SPEC-1.0 now supplies the adopted canonical Survey mathematics beneath Spatial Ground, and SG-WORLD-SPACE-INSTANCE-0001 supplies the adopted canonical World-membership truth consumed by the next layer. This relationship states the demonstrated spatial dependency relevant to Spatial Ground and does not establish a universal ordering for every remaining Architecture domain.
Upstream Handoff
Spatial Ground depends upon the Foundational Survey Fabric for canonical Survey reference, exact coordinate meaning, primitive geometry, predicates, normalization, precision / refinement semantics, and governed interchange. Those foundations are supplied from below; Spatial Ground does not recreate them.
Adopted FSF Foundation
FSF-SPEC-1.0 supplies CRPC, ECEM, Point / Segment / SCPE geometry, exact predicates, deterministic normalization, the canonical frame, FSF-CJSON-1.0, the canonical Survey Domain, and the governed production placement envelope.
Canonical Survey Bounds
H = 1,000,000 Pang; D = [-1,000,000,+1,000,000]²; P = [-500,000,+500,000]². Canonical World-space is proven strictly inside interior(P), which lies strictly inside interior(D).
Gate B Standing
Gate B is complete. Spatial Ground consumes the adopted FSF foundation without redefining it, and the canonical World-space production instance has passed final Conformance and reconstruction proof.
Architectural Handoff Rule Spatial Ground may consume what the Survey Fabric has canonically established. It may not complete the Survey Fabric from above.
Governing Record
The adopted Requirements are the governing normative record for Spatial Ground. The resolution, Gate 0, and classification records preserve the architectural reasoning and evidence that produced the adopted Requirements; they are not alternate sources of World-space truth.

Canonical Scope
Spatial Ground operates over canonical Survey space and preserves a single World-membership truth. Under SG-SPEC-1.0, membership is exact, total, two-valued, and deterministic over valid Survey meanings; invalid Survey input is rejected before World-membership evaluation. Spatial Ground may consume Survey geometry, topology, scale, precision, refinement, and other Survey-owned mathematics, but it does not redefine or duplicate those foundations.
Canonical World-space is strictly contained within the governed FSF production placement envelope and therefore does not coincide with the entire Survey Domain. Non-World-space is the relational complement of World-space within valid Survey space and receives no independent intrinsic meaning from Spatial Ground.
The adopted World-space instance is intentionally minimal: one connected, closed, hole-free World region expressed through one primary canonical FSF SCPE and referenced through one fsf root in the production SG-CJSON 1.0 Ground Definition. Unrestricted Boolean / composite-result closure remains outside the current production profile.
The canonical limit is a consequence of membership. It may coincide with a recognizable geographic or experiential edge, but coincidence does not make those things identical. Visual form and experiential geography remain higher-layer concerns.
What Spatial Ground Does Not Own
Spatial Ground does not own Parcel truth, higher-layer eligibility, visual World Form, terrain, Regions, Clusters, infrastructure meaning, ownership, rights, settlement, experience, or cultural and economic interpretation. It also does not own Survey reference, coordinates, geometry, topology, scale, measurement, precision, or refinement mechanics.
This narrow responsibility is intentional. Lower layers preserve smaller and more permanent truths; higher layers may add meaning without acquiring authority to alter the World membership beneath them. The same rule applies downward: Spatial Ground may not resolve open Survey mathematics merely because World-membership work would benefit from an answer.
Active Spatial Handoff
Spatial Ground → General Spatial Interpretation. The lower spatial foundation is now established: FSF supplies canonical Survey truth, Spatial Ground supplies adopted canonical World membership, and General Spatial Interpretation is the next strict spatial layer. Higher layers must consume the adopted Ground without redefining it.
