From 1858314e77eee703837487a59936e3deed7c654f Mon Sep 17 00:00:00 2001 From: zackees Date: Mon, 24 Aug 2026 23:28:24 -0700 Subject: [PATCH] feat(license): restructure per AI legal review findings (#2-#8) Rewrite the license as a single self-contained instrument: a modified MPL 2.0 (renamed per MPL 10.3, FastLED as steward) with the Additional Terms as Section 11 and adapted Exhibits. Close the Secondary-License bypass with Exhibit B, make Section 11.3 an express condition of the copyright grant only, replace "First Sale" with a per-version, modifier-bound "Triggering Transfer", and make the zero-day timing model operative: public-fork development is standing compliance, units shipped before publication remain unlicensed, publication reinstates prospectively under Section 5.1. De-legalize the AI-agent guidance (authorization-first, informational only, excluded from Section 3.4 notice integrity), add ai-policy.toml, shrink the source header to three lines, move RC status into the SPDX identifier (-rc1), and enforce the LEGAL-REVIEW.md gate mechanically in the header tool. Record all applied decisions for attorney ratification.

The license was restructured in response. That review is input +to — not a substitute for — the attorney review above. + +## Decisions applied in the restructuring (pending attorney ratification) + +These were applied with the review's recommended defaults, plus steward +direction on timing.

The contributor patent grant under 2.1(b) is + deliberately NOT conditioned on Section 11.3 — contributors never + agreed to have their patents armed as a sales-disclosure tripwire. + Confirm this allocation. +3. **Exhibit B is attached; Secondary-License distribution is closed** + (Sections 1.5, 3.3, 11.6). This makes the license deliberately + GPL-incompatible in exchange for making Section 11.3 non-bypassable. + Confirm this trade-off with the steward; it cannot be had both ways. +4. **Zero-day timing is intentional and per-version** (steward decision, + 2026-08-24). The development period before first commercial transfer + is the compliance window; developing in a public fork is standing + compliance (11.3(b)). There is no post-transfer cure that + retroactively authorizes: units reproduced or transferred before + publication remain unlicensed (11.3(f)), while publication reinstates + prospectively under Section 5.1.

Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. -The complete Mozilla Public License Version 2.0 contained in `MPL-2.0.txt` is -incorporated into this License by reference.

FastLED Additional Terms +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. The Covered Software is Incompatible With +Secondary Licenses (see Sections 1.5 and 11.6), and this License does +not permit You to distribute the Covered Software under the terms of any +Secondary License. + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. Informational +lines referencing AI coding agent guidance are not license notices; see +Section 11.7. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. This Section 3.5 does not authorize the imposition of +additional license terms on any recipient; the FastLED Additional Terms +in Section 11 are part of this License itself, not terms offered under +this Section. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation (including a binding +export-control determination) then You must: (a) comply with the terms +of this License to the maximum extent possible; and (b) describe the +limitations and the code they affect. Such description must be placed in +a text file included with all distributions of the Covered Software +under this License. Except to the extent prohibited by statute or +regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. A private +contractual obligation of confidentiality is not a statute, judicial +order, or regulation for the purposes of this Section; see Section +11.3(g) for the separate-license alternative. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. Reinstatement under this Section is +prospective only; see Section 11.3(f). + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6. Disclaimer of Warranty * +* ------------------------- * +* * +* Covered Software is provided under this License on an "as is" * +* basis, without warranty of any kind, either expressed, implied, or * +* statutory, including, without limitation, warranties that the * +* Covered Software is free of defects, merchantable, fit for a * +* particular purpose or non-infringing. The entire risk as to the * +* quality and performance of the Covered Software is with You. * +* Should any Covered Software prove defective in any respect, You * +* (not any Contributor) assume the cost of any necessary servicing, * +* repair, or correction. This disclaimer of warranty constitutes an * +* essential part of this License. No use of any Covered Software is * +* authorized under this License except under this disclaimer. * +* * +************************************************************************ + +************************************************************************ +* * +* 7. Limitation of Liability * +* -------------------------- * +* * +* Under no circumstances and under no legal theory, whether tort * +* (including negligence), contract, or otherwise, shall any * +* Contributor, or anyone who distributes Covered Software as * +* permitted above, be liable to You for any direct, indirect, * +* special, incidental, or consequential damages of any character * +* including, without limitation, damages for lost profits, loss of * +* goodwill, work stoppage, computer failure or malfunction, or any * +* and all other commercial damages or losses, even if such party * +* shall have been informed of the possibility of such damages. This * +* limitation of liability shall not apply to liability for death or * +* personal injury resulting from such party's negligence to the * +* extent applicable law prohibits such limitation. Some * +* jurisdictions do not allow the exclusion or limitation of * +* incidental or consequential damages, so this exclusion and * +* limitation may not apply to You. * +* * +************************************************************************ + +8. Litigation +------------- + +Any litigation relating to this License may be brought only in the +courts of a jurisdiction where the defendant maintains its principal +place of business and such litigation shall be governed by laws of that +jurisdiction, without reference to its conflict-of-law provisions. +Nothing in this Section shall prevent a party's ability to bring +cross-claims or counter-claims. + +9. Miscellaneous +---------------- + +This License, including the FastLED Additional Terms in Section 11, +represents the complete agreement concerning the subject matter hereof. +The AI coding agent guidance referenced in Section 11.7 is informational +only and is not part of this agreement. If any provision of this +License is held to be unenforceable, such provision shall be reformed +only to the extent necessary to make it enforceable. Any law or +regulation which provides that the language of a contract shall be +construed against the drafter shall not be used to construe this +License against a Contributor. + +10. Versions of the License --------------------------- -2.1. Definitions +10.1. New Versions + +FastLED is the license steward. Except as provided in Section 10.3, no +one other than the license steward has the right to modify or publish +new versions of this License. Each version will be given a +distinguishing version number. + +10.2. Effect of New Versions + +You may distribute the Covered Software under the terms of the version +of the License under which You originally received the Covered Software, +or under the terms of any subsequent version published by the license +steward. + +10.3. Modified Versions + +If you create software not governed by this License, and you want to +create a new license for such software, you may create and use a +modified version of this License if you rename the license and remove +any references to the name of the license steward (except to note that +such modified license differs from this License). + +10.4. Distributing Source Code Form that is Incompatible With Secondary +Licenses -"FastLED" means Covered Software originating in the official FastLED -repository. +If You choose to distribute Source Code Form that is Incompatible With +Secondary Licenses under the terms of this version of the License, the +notice described in Exhibit B of this License must be attached. -"Modified FastLED" means FastLED containing Modifications as that term is -defined by MPL 2.0. It does not include separate files of a Larger Work that do -not contain or derive from Covered Software. +11. FastLED Additional Terms +---------------------------- -"First Sale" means the first sale, lease, or other transfer for monetary -compensation of Modified FastLED, or of software, firmware, or hardware that -includes Modified FastLED. +11.1. Additional Definitions -2.2. Proprietary Larger Works +Capitalized terms used in this Section 11 and not defined here have the +meanings given in Section 1. -For clarity, independent application code, sketches, firmware logic, products, -plugins, and other works that merely call FastLED APIs are separate files of a -Larger Work. They do not become Covered Software solely through use, -compilation, static or dynamic linking, embedding, distribution, deployment, -or sale. Such Larger Work material may remain proprietary, subject to -compliance with MPL 2.0 and these Additional Terms for Covered Software. +"Official FastLED Repository" means the Git repository located at +https://github.com/FastLED/FastLED as of the publication date of this +License, or such successor location as the license steward designates by +a notice published in the repository most recently designated as +official under this definition (for example, a git tag or a top-level +file identifying the new location). If more than one repository claims +to be the Official FastLED Repository following a fork or governance +dispute, the Official FastLED Repository is the one whose commit history +is a continuous, ancestor-inclusive descendant of the commit history of +the repository identified above and that is maintained by or with the +authorization of the license steward. -2.3. Public Availability on the Date of First Sale +"FastLED" means Covered Software originating in the Official FastLED +Repository. -If You make a First Sale of Modified FastLED, You must satisfy one of the -following public reporting mechanisms on or before the date of that First Sale. -There is no post-sale grace period. +"Modified FastLED" means FastLED containing Modifications as defined in +Section 1.10. It does not include separate files of a Larger Work that +do not contain or derive from Covered Software. Each distinct version or +state of Modified FastLED is a separate body of Modified FastLED for the +purposes of Section 11.3; publication of one version does not satisfy +Section 11.3 for any other version. -(a) **Public fork.** Publish the complete Source Code Form of the Modified - FastLED in a repository that is publicly discoverable, readable, cloneable, - and forkable without payment or special access. The preferred location is a - public fork of the official FastLED repository on the same source-hosting - platform. The fork must identify the upstream FastLED commit or release - from which it was derived. If that platform cannot provide a public fork, - an equivalent public Git repository is sufficient. +"Triggering Transfer" means any transfer to a third party, for monetary +or other valuable consideration, of a version of Modified FastLED, or of +software, firmware, or hardware embodying that version, where the +transfer is made by, or with the authorization of, the person that +created or commissioned the Modifications in that version. A Triggering +Transfer also occurs when a version of Modified FastLED is made +available at no charge in connection with a product, device, or service +for which the person that created or commissioned the Modifications, or +its licensee, receives monetary or other valuable consideration.

Proprietary Larger Works + +For clarity, independent application code, sketches, firmware logic, +products, plugins, and other works that merely call FastLED APIs are +separate files of a Larger Work. They do not become Covered Software +solely through use, compilation, static or dynamic linking, embedding, +distribution, deployment, or sale. Such Larger Work material may remain +proprietary, subject to compliance with this License for the Covered +Software itself. However, a file that contains Covered Software — +including by textual inclusion, amalgamation, macro expansion, or +copying — is a Modification under Section 1.10(b) regardless of this +Section, and the Executable Form of Covered Software is itself Covered +Software under Section 1.4. + +11.3. Public Availability Condition + +(a) Condition. You may reproduce and distribute a version of Modified + FastLED only if, on or before the date of the earliest Triggering + Transfer of that version (measured in the time zone of Your + principal place of business), the complete Source Code Form of that + version is Publicly Available through at least one of the mechanisms + in Section 11.3(c). This condition applies separately to each + version. The development period before a Triggering Transfer is the + time in which to establish compliance; there is no compliance + period after a Triggering Transfer, and Section 11.3(f) governs the + consequences of a Triggering Transfer that precedes publication. + +(b) Standing compliance. If You develop Modified FastLED in a + repository that is Publicly Available at all times from the start of + development through the date of a Triggering Transfer, and that + repository identifies the upstream FastLED commit or release from + which the work is derived, You satisfy this Section for every + version contained in that repository as of that date, with nothing + further required. + +(c) Mechanisms. The Source Code Form is made Publicly Available by: + + (i) Public repository. Publishing the complete Source Code Form of + the version in a Publicly Available Git repository that + identifies the upstream FastLED commit or release from which it + was derived. A public fork of the Official FastLED Repository + is the preferred location; any equivalent Publicly Available + Git repository is sufficient. + + (ii) Public patch. Publishing a report that identifies the exact + upstream commit identifier used as the base and contains a + complete unified diff against that commit (equivalent to + `git diff ...HEAD`), together with a short + description of the modification. The base commit and diff must + be sufficient to reconstruct the complete Source Code Form of + the version deterministically. The preferred location is a + public issue in the Official FastLED Repository or in a + reporting location the license steward designates; a Publicly + Available location under Your control is equally sufficient. + +(d) Duration. Source Code Form published under this Section must remain + Publicly Available for at least three (3) years after the last + Triggering Transfer of that version, and in any event for as long as + You distribute the Executable Form of that version. + +(e) Third-party interference. If a submission made under Section + 11.3(c)(ii) to the Official FastLED Repository is rejected, blocked, + removed, or rendered inaccessible by a person other than You, or if + the Official FastLED Repository or its hosting platform is + unavailable to You for reasons outside Your control, You remain + compliant if You republish the same material in a Publicly Available + location under Your control within thirty (30) days of becoming + aware of the interference or unavailability. No act or omission of + the license steward or the maintainers of the Official FastLED + Repository places You in breach of this Section by itself. + +(f) Timing and consequences. Section 5.1 applies to any failure to + satisfy this Section. Publication after the date of a Triggering + Transfer does not retroactively authorize any reproduction or + distribution that occurred before publication: copies of the version + reproduced or transferred while this Section was unsatisfied were + not licensed under Section 2.1(a) when made or transferred, and + later publication does not change that. Publication does restore + Your rights prospectively, subject to Section 5.1. + +(g) Separate license. This Section does not apply to a version of + Modified FastLED for which You have obtained a separate written + license from the license steward expressly excusing compliance with + this Section. + +(h) Relationship to Sections 3.1 and 3.2. This Section is in addition + to, and does not replace, Your obligations under Sections 3.1 and + 3.2. Publication under Section 11.3(c)(i) satisfies Section 3.2(a) + with respect to the Modified FastLED if You inform recipients of the + Executable Form of the location of the published Source Code Form. + Publication under Section 11.3(c)(ii) does not by itself satisfy + Section 3.2(a). + +11.4.
