 1. **At PR-creation time, follow the [PR-creation flow](docs/agents/release-and-versioning.md#pr-creation-flow) in `docs/agents/release-and-versioning.md`.** Every PR gets a `target/vN` label; breaking changes additionally get a `breaking-change` label, a `⚠️ Breaking change` callout, a `version.json` major bump in the same PR, and a `CHANGELOG.md` entry. This is non-negotiable — review will block.

Tool wrapper JSON `$schema` URLs (63 files) and `*.Generated.cs` "Generated from" comments updated from `nuke-build/nuke/master/source/` to `ChrisonSimtian/Fallout/main/src/`.

NUKE attribution in README/CONTRIBUTING/CLAUDE.md/CHANGELOG history and pedagogical test fixtures intentionally kept.
 
 ### Misc
+- **Stripped per-file license headers; `LICENSE` is now the single source of truth.** The 4-line `// Copyright … Maintainers of Fallout. // Originally based on NUKE …` block has been removed from all 614 first-party `.cs` files under `src/`, `tests/`, `build/`, and the repo root. MIT compliance is satisfied by `LICENSE` at the repo root (which preserves matkoch's "Maintainers of NUKE 2017-2025" copyright), README acknowledgement of the NUKE origin, and `PackageLicenseExpression="MIT"` on every NuGet package. Vendored third-party code (`src/Persistence/Fallout.Persistence.Solution/`, Microsoft MIT) retains its own copyright headers untouched. Convention docs (`AGENTS.md`, `docs/agents/conventions.md`, `docs/architecture.md`, `CONTRIBUTING.md`) updated to match.
 - **Fixed `GetNuGetReleaseNotes` escaping** — now URL-encodes `;` in addition to `,`. Without this, semicolons in changelog bullets split the MSBuild `-p:PackageReleaseNotes=` value and crashed Pack.
 - **Dropped `JetBrains.Annotations`** (#76).
 - **Docs**: dependency overview (#85, #87), architecture overview, v11/v12 plugin-architecture roadmap, costs/sponsorship transparency (#56), README badge row (#62) + Repobeats activity image (#63), rebrand namespace mapping (#53).
