# Spatial Ground — Canonical World-Space Instance Adoption Act **Adoption Act:** `SG-ACT-INSTANCE-2026-0001` **Institution:** The Atlas · Spatial Ground **Creator Period:** Day #132 · October 6, 2026 **Adoption Authority:** The Creator, acting through The Atlas during the Creator Period **Adoption Target:** `SG-WORLD-SPACE-INSTANCE-0001` **Record State:** ADOPTED **Effective Status:** CANONICAL WORLD-SPACE INSTANCE ADOPTED --- ## 1. Authority The Spatial Ground Governance Baseline establishes the Creator, acting through The Atlas during the Creator Period, as the authority competent to adopt the canonical World-space instance. Evidence, implementation, publication, certification, custody, technical control, popularity, or agreement do not themselves create canonical status. This Act does. --- ## 2. Adoption Preconditions The required institutional sequence has been completed: ```text Spatial Ground Requirements — ADOPTED Gate A — COMPLETE FSF-SPEC-1.0 — CANONICALLY ADOPTED Spatial Ground Specification SG-SPEC-1.0 — ADOPTED Gate B — COMPLETE Canonical World-space production sequence: 5A — COMPLETE 5B — COMPLETE 5C — COMPLETE 5D — COMPLETE 5E — COMPLETE 5F — COMPLETE 5G — COMPLETE 5H — COMPLETE 5I — COMPLETE ``` The final production-instance Conformance and reconstruction proof is: ```text PASS ``` with: ```text independent implementation A — PASS independent implementation B — PASS cross-implementation mismatch — 0 ``` No remaining production-instance blocker is identified. --- ## 3. Canonical Instance Identity The adopted canonical World-space instance is designated: ```text SG-WORLD-SPACE-INSTANCE-0001 ``` This identifier denotes the adopted Spatial Ground instance. It is distinct from: - the FSF geometry artifact; - the FSF production-reference identifier; - the SG-CJSON serialization; - the Adoption Act identifier; - any repository path or storage location. The identity of canonical World-space is semantic rather than artifact-specific. --- ## 4. Adopted Survey Geometry The one canonical Survey geometry consumed by the adopted instance is: ```text FSF production reference: FSF-WORLD-SCPE-0001 canonical geometry artifact: SG_World_Production_SCPE_01.fsf-cjson.json governing Survey Specification: FSF-SPEC-1.0 canonical Survey serialization: FSF-CJSON-1.0 ``` Canonical FSF-CJSON SHA-256 integrity evidence: ```text 013248a563f979c56bc34c7951cd542eb990e88c486d0bbbe8b2e9500ea54c54 ``` The geometry is one valid: ```text Simple Closed Polygonal Extent (SCPE) ``` with: ```text connected — TRUE closed — TRUE simple — TRUE hole-free — TRUE boundary-inclusive — TRUE normalized traversal — COUNTERCLOCKWISE vertex count after normalization — 128 ``` Its exact production bounding extrema are: ```text x = [-450,000,+450,000] Pang y = [-423,044.1,+423,044.1] Pang ``` and it is proven strictly contained within: ```text [-500,000,+500,000]² ``` with an exact minimum reserve of: ```text 50,000 Pang ``` --- ## 5. Adopted Ground Definition The primary canonical Ground Definition for the adopted instance is: ```text SG_World_Ground_Definition_01.sg-cjson.json ``` Its canonical SG-CJSON SHA-256 integrity evidence is: ```text 40fd371aa7239495f7c939f4c2b6ae9e50cdbaaa2282fe1b237bfa7bf7df2aca ``` Its production expression is exactly: ```text one root op = fsf value = FSF-WORLD-SCPE-0001 ``` There is no Ground-level: - union; - intersection; - difference; - second independently authoritative geometry; - synthetic FSF test dependency. The governing representation is: ```text SG-CJSON 1.0 ``` under: ```text SG-SPEC-1.0 CMPM-1.0 closed-world-space ``` --- ## 6. Canonical Membership Meaning For every valid canonical Survey location `x`, the adopted Ground Definition determines one exact membership result: ```text WORLD or NON_WORLD ``` Survey invalidity is resolved before World-membership evaluation. For this adopted instance: ```text INTERIOR of FSF-WORLD-SCPE-0001 → WORLD BOUNDARY of FSF-WORLD-SCPE-0001 → WORLD EXTERIOR within valid Survey space → NON_WORLD invalid Survey reference → INVALID_INPUT before membership ``` Thus the adopted World-space is the complete closed FSF SCPE: ```text boundary ∪ interior ``` and no additional Ground region is implied. --- ## 7. Conformance and Reconstruction Evidence The adoption relies upon the completed production proof: ```text SG_World_Production_Conformance_Reconstruction_Proof_01.json ``` SHA-256: ```text aae1afc5697f83a712681c83badde414815a518220971c7d75bf50a5f876eab2 ``` The proof demonstrated exact reconstruction from preserved canonical artifacts through two independent implementations. Observed canonical cases include: ```text origin → WORLD canonical start vertex → WORLD first boundary-edge midpoint → WORLD (490000,0) → NON_WORLD (0,490000) → NON_WORLD (750000,0) → NON_WORLD (1000001,0) → INVALID_INPUT ``` The adopted instance therefore satisfies the reconstruction obligation without dependence on the original design-space source, renderer, operational database, network service, cache, or original implementation. --- ## 8. Layer Boundary This Act does not transfer Survey authority into Spatial Ground. The boundary remains: ```text FSF supplies canonical spatial reference and mathematics. Spatial Ground adds canonical participation in The World. ``` Accordingly: ```text FSF-CJSON defines the canonical Survey geometry. SG-CJSON defines the canonical Ground membership expression. ``` Spatial Ground does not independently own the polygon mathematics. --- ## 9. Canonical Effect of Adoption Upon execution of this Act: ```text candidate production World-space ↓ ADOPTED CANONICAL WORLD-SPACE ``` The following statement is now authoritative within Spatial Ground: > **The World exists exactly at the Survey locations classified WORLD by `SG-WORLD-SPACE-INSTANCE-0001` under `SG-SPEC-1.0`, whose sole production expression references `FSF-WORLD-SCPE-0001` under `FSF-SPEC-1.0`.** No prior candidate, normalized design silhouette, redraw artifact, visual reference, production-preparation record, test fixture, or implementation result is a competing canonical World-space definition. They remain evidence, lineage, or derived material according to their proper institutional role. --- ## 10. Permanence Effect Adoption exhausts Creator design authority over the canonical World-space instance. Spatial Ground contains no dormant architectural authority or ordinary internal mechanism for changing established World-space. Meaning-preserving representation maintenance may occur only where semantic equivalence is established under the governing Specification. A change to the foundational World-space meaning is not ordinary maintenance, implementation evolution, correction of presentation, or file replacement. Any valid foundational revision affecting the adopted World-space must return to the applicable upstream constitutional authority. This Act does not create such a revision mechanism. --- ## 11. Representation Independence The adopted spatial truth is not made canonical merely by these filenames, hashes, paths, or storage media. Those artifacts preserve and prove the adopted meaning. Accordingly: ```text repository relocation ≠ World-space change storage migration ≠ World-space change lossless equivalent representation ≠ World-space change implementation replacement ≠ World-space change ``` provided semantic identity remains proven under the governing Specifications. Conversely, byte reuse or filename reuse cannot legitimize a semantic change. --- ## 12. Formal Adoption By this Act, the Creator, acting through The Atlas during the Creator Period, hereby adopts: ```text SG-WORLD-SPACE-INSTANCE-0001 ``` as the singular canonical Spatial Ground World-space instance of BitPangea. The adoption is effective on: ```text October 6, 2026 Creator Period Day #132 ``` Formal disposition: > **ADOPTED — CANONICAL WORLD-SPACE INSTANCE ESTABLISHED.** --- ## 13. Canonical Standing After This Act ```text Spatial Ground Requirements — ADOPTED Gate A — COMPLETE FSF-SPEC-1.0 — CANONICALLY ADOPTED SG-SPEC-1.0 — ADOPTED Gate B — COMPLETE canonical FSF production geometry — ESTABLISHED canonical SG-CJSON Ground Definition — ESTABLISHED production Conformance — PASS production reconstruction — PASS SG-WORLD-SPACE-INSTANCE-0001 — ADOPTED CANONICAL WORLD-SPACE INSTANCE — ESTABLISHED ``` --- ## 14.

Its canonical ground is adopted.**
