The base MPL-2.0 terms apply except where explicitly modified by the Exhibits below. Like a palimpsest manuscript where each layer builds upon what came before, this license recognizes that creative works carry history, context, and meaning that transcend mere code or text. -------------------------------------------------------------------------------- SECTION 1: BASE LICENSE -------------------------------------------------------------------------------- This License incorporates the full text of Mozilla Public License 2.0 by reference. The complete PMPL-1.0-or-later text is available at: https://www.mozilla.org/en-US/MPL/2.0/ All terms, conditions, and definitions from PMPL-1.0-or-later apply except where explicitly modified by the Exhibits in this License. -------------------------------------------------------------------------------- SECTION 2: ADDITIONAL DEFINITIONS -------------------------------------------------------------------------------- 2.1. "Emotional Lineage" means the narrative, cultural, symbolic, and contextual meaning embedded in Covered Software, including but not limited to: protest traditions, cultural heritage, trauma narratives, and community stories. 2.2. "Provenance Metadata" means cryptographically signed attribution information attached to or associated with Covered Software, including author identities, timestamps, modification history, and lineage references. 2.3. "Non-Interpretive System" means any automated system that processes Covered Software without preserving or considering its Emotional Lineage, including but not limited to: AI training pipelines, content aggregators, and automated summarization tools. 2.4. "Quantum-Safe Signature" means a cryptographic signature using algorithms resistant to attacks by quantum computers, as specified in Exhibit B. -------------------------------------------------------------------------------- SECTION 3: ETHICAL USE REQUIREMENTS -------------------------------------------------------------------------------- In addition to the rights and obligations under PMPL-1.0-or-later: 3.1. Emotional Lineage Preservation You must make reasonable efforts to preserve and communicate the Emotional Lineage of Covered Software when distributing or creating derivative works. This includes maintaining narrative context, cultural attributions, and symbolic meaning where documented. 3.2. Non-Interpretive System Notice If You use Covered Software as input to a Non-Interpretive System, You must: (a) document such use in a publicly accessible manner; and (b) not claim that outputs of such systems carry the Emotional Lineage of the original work without explicit permission from Contributors. 3.3. Ethical Use Declaration Commercial use of Covered Software requires acknowledgment that You have read and understood Exhibit A (Ethical Use Guidelines) and agree to act in good faith accordance with its principles. See Exhibit A for complete Ethical Use Guidelines. -------------------------------------------------------------------------------- SECTION 4: PROVENANCE REQUIREMENTS -------------------------------------------------------------------------------- 4.1. Metadata Preservation You must not strip, alter, or obscure Provenance Metadata from Covered Software except where technically necessary and with clear documentation of any changes. 4.2. Quantum-Safe Provenance (Optional) Contributors may sign their Contributions using Quantum-Safe Signatures. If Quantum-Safe Signatures are present, You must preserve them in all distributions. 4.3. Lineage Chain When creating derivative works, You should extend the provenance chain to include Your own contributions, maintaining cryptographic linkage to prior Contributors where feasible. See Exhibit B for Quantum-Safe Provenance specifications. -------------------------------------------------------------------------------- SECTION 5: GOVERNANCE -------------------------------------------------------------------------------- 5.1. Stewardship Council This License is maintained by the Palimpsest Stewardship Council, which may issue clarifications, interpretive guidance, and future versions. 5.2. Version Selection You may use Covered Software under this version of the License or any later version published by the Palimpsest Stewardship Council. 5.3. Dispute Resolution Disputes regarding interpretation of Ethical Use Requirements (Section 3) should first be submitted to the Palimpsest Stewardship Council for non-binding guidance before pursuing legal remedies. -------------------------------------------------------------------------------- SECTION 6: COMPATIBILITY -------------------------------------------------------------------------------- 6.1. PMPL-1.0-or-later Compatibility Covered Software under this License may be combined with software under PMPL-1.0-or-later. The combined work must comply with both licenses. 6.2. Secondary Licenses The Secondary License provisions of PMPL-1.0-or-later Section 3.3 apply to this License. -------------------------------------------------------------------------------- EXHIBITS -------------------------------------------------------------------------------- Exhibit A - Ethical Use Guidelines Exhibit B - Quantum-Safe Provenance Specification See separate files: - EXHIBIT-A-ETHICAL-USE.txt - EXHIBIT-B-QUANTUM-SAFE.txt -------------------------------------------------------------------------------- END OF PALIMPSEST-MPL-1.0 LICENSE TEXT -------------------------------------------------------------------------------- For exhibits, specifications, provenance rules, and governance: https://github.com/hyperpolymath/palimpsest-license For legal frameworks and jurisdictional analysis: See /legal/frameworks/ For provenance and audit tooling: See /tools/ and /spec/PROVENANCE-SPEC.adoc For questions about this License: - Repository: https://github.com/hyperpolymath/palimpsest-license - Council: contact via repository Issues
