# Spatial Ground Requirements Adoption Act ## SG-ACT-REQ-2026-0001 **Institution:** The Atlas · Spatial Ground **Act Type:** Requirements Adoption **Record State:** ADOPTED **Effective Date:** September 23, 2026 **Creator Period Day:** Day #119 **Primary Normative Artifact:** `/theatlas/spatial-ground/requirements/spatial-ground-requirements.md` **Governance Path:** `/theatlas/spatial-ground/governance/SG_Requirements_Adoption_Act.md` --- ## 1. Authority This Act is issued by the **Creator acting through The Atlas during the Creator Period**, under the Spatial Ground governance architecture established before Gate A. The governing record-state model is: ```text Candidate → Adopted → Superseded ``` Canonical status arises from a valid recorded Adoption Act. Technical correctness, publication, implementation, certification, custody, possession, hosting, popularity, majority agreement, operational use, or technical control do not themselves confer canonical authority. --- ## 2. Subject of Adoption This Act applies only to the **Spatial Ground Requirements** preserved at: ```text /theatlas/spatial-ground/requirements/spatial-ground-requirements.md ``` The Requirements state what Spatial Ground must preserve, permit, exclude, and prove. They govern the architectural envelope within which later Spatial Ground Specification, Conformance, preservation, reconstruction, implementation, and instance-adoption work must remain. --- ## 3. Adoption By this Act, the Spatial Ground Requirements record state is changed from: ```text Candidate / Draft for Adoption Review ``` to: ```text Adopted ``` The adopted Requirements become the governing Requirements record for Spatial Ground. **Gate A is COMPLETE.** --- ## 4. Effect of Adoption Requirements adoption establishes authoritative Spatial Ground Requirements. It does **not**: - adopt a Spatial Ground Specification; - select or adopt a canonical World-space instance; - make any particular Survey location World-space; - transfer Foundational Survey Fabric mathematics into Spatial Ground ownership; - create higher-layer Parcel, terrain, Region, ownership, rights, governance, cultural, economic, or experiential meaning; - make implementation, publication, certification, or operation a source of canonical authority. Requirements adoption is institutionally distinct from: ```text Requirements adoption Specification adoption canonical World-space instance adoption ``` Each requires its own valid institutional act or completion mechanism. --- ## 5. Architectural Boundary The adopted Requirements preserve the governing lower-layer / Ground distinction: > **FSF supplies canonical spatial reference and mathematics. Spatial Ground adds canonical participation in The World.** Spatial Ground consumes Survey facts by reference. It does not redefine, duplicate, fork, rescale, or independently reinterpret Survey-owned spatial truth. A lower layer constrains what a higher layer cannot violate. A higher layer does not complete a lower layer from above. --- ## 6. Requirements Authority The adopted Requirements govern what must remain true of Spatial Ground, including: - constitutional subordination; - one canonical World-space; - non-empty World-space; - connectedness; - exact, total, two-valued, deterministic membership; - one canonical definition; - sole dependence on the canonical Ground definition and inherited Survey truth; - permanence after canonical instance adoption; - representation independence; - finite expression and decidability; - refinement closure; - reference to the Foundational Survey Fabric without redefinition; - membership-only semantics; - explicit upward guarantees and non-guarantees; - canonical status only through valid adoption. Consequences and references derived from these Requirements do not create duplicate independent normative authority. --- ## 7. What Remained Open at This Act At the moment of Requirements adoption, this Act did not decide: - the final formal membership model; - the Spatial Ground Specification; - the canonical machine representation; - the exact canonical World-space production instance; - the final Conformance and reconstruction evidence for that instance. Those matters belonged to later institutional stages. Their later completion does not alter the meaning of this Requirements Adoption Act. --- ## 8. Permanence and Later Acts This Act must remain distinguishable from later Spatial Ground acts. In particular, later adoption of a Spatial Ground Specification or canonical World-space instance must not be retroactively treated as having occurred through this Requirements Act. Likewise, this Act does not authorize future alteration of established World-space. Once the canonical World-space instance is validly adopted, its permanence is governed by the adopted Spatial Ground Requirements and the applicable instance Adoption Act. --- ## 9. Gate A Disposition The formal disposition is: ```text SPATIAL GROUND REQUIREMENTS — ADOPTED GATE A — COMPLETE ``` The adopted Requirements are the governing normative Requirements record for Spatial Ground. --- ## 10. Record Integrity The primary normative Requirements artifact remains: ```text /theatlas/spatial-ground/requirements/spatial-ground-requirements.md ``` This governance record establishes the institutional act that placed that Requirements artifact into the **Adopted** state. The Requirements artifact and this Adoption Act have different roles: ```text Requirements → state what must remain true Adoption Act → establishes the Requirements record's canonical institutional status ``` Neither substitutes for the other. --- ## 11. Publication-Recovery Note This file restores the governance artifact expected at the established public repository path: ```text /theatlas/spatial-ground/governance/SG_Requirements_Adoption_Act.md ``` The underlying act was already executed and preserved in the institutional record as **SG-ACT-REQ-2026-0001**. Restoring this missing repository artifact does **not** constitute a new adoption, re-adoption, amendment, or change in authority. --- ## Final Recorded State **ACT:** SG-ACT-REQ-2026-0001 **REQUIREMENTS:** ADOPTED **GATE A:** COMPLETE **CANONICAL REQUIREMENTS RECORD:** `/theatlas/spatial-ground/requirements/spatial-ground-requirements.md` --- **End of Spatial Ground Requirements Adoption Act — SG-ACT-REQ-2026-0001**
