+# Issue 7 Case Study: Correct Project License to The Unlicense
+
+Date: 2026-05-01
+
+Issue: https://github.com/linksplatform/doublets-web/issues/7
+Pull request: https://github.com/linksplatform/doublets-web/pull/8
+
+## Goal
+
+Correct every repository-owned license surface from the previous MIT OR Apache-2.0 metadata to The Unlicense, preserve the supporting evidence under `docs/case-studies/issue-7`, and add a regression check that keeps the public metadata aligned.
+
+## Evidence Collected
+
+- Issue 7 metadata and comments are saved under `evidence/issue-7.json` and `evidence/issue-7-comments.json`.
+- Pull request 8 metadata, comments, reviews, and review comments are saved under `evidence/pr-8*.json`.
+- The SPDX record for `Unlicense` is saved in `evidence/spdx-unlicense.json`.
+- The canonical Unlicense text is saved in `evidence/UNLICENSE.txt`.
+- npm package metadata guidance was saved in `evidence/npm-package-json.html`.
+
+## Timeline
+
+- 2021-12-09: `linksplatform/doublets-web` was created. GitHub API metadata reported the repository license as Apache-2.0 before this fix.
+- 2026-05-01 05:28 UTC: PR 6 merged the CI/CD revival and left the crate metadata, README badge, README license section, and test app metadata on MIT OR Apache-2.0.
+- 2026-05-01 09:01 UTC: Issue 7 was opened requesting that the license be corrected to Unlicense/Public Domain in all places.
+- 2026-05-01 09:01 UTC: Draft PR 8 was created for the issue.
+- 2026-05-01: This investigation found no issue comments, PR comments, reviews, or review comments requiring additional constraints.
+
+## Requirements
+
+- Change the main crate metadata to the SPDX identifier `Unlicense`.
+- Replace root MIT/Apache license files with the Unlicense text.
+- Update README badge and license section.
+- Update the `testapp` metadata and license files because they are tracked repository content.
+- Preserve raw issue/PR/evidence data under `docs/case-studies/issue-7`.
+- Include a repeatable check that fails when old license markers come back.
+- Bump the package version so the release workflow has a new npm package version to publish.
+
+## Root Cause
+
+The repository still contained the dual-license setup from earlier project scaffolding and CI modernization work:
+
+- `Cargo.toml` declared `license = "MIT OR Apache-2.0"`.
+- `README.md` advertised an MIT/Apache badge and linked `LICENSE_MIT` and `LICENSE_APACHE`.
+- Root and `testapp` license files contained MIT and Apache-2.0 texts.
+- `testapp/package.json` and `testapp/package-lock.json` declared `(MIT OR Apache-2.0)`.
+
+Because these surfaces are maintained independently, changing only one file would leave package metadata, GitHub license detection, or documentation inconsistent.
+
+## External Facts
+
+SPDX lists the short license identifier as `Unlicense`, with the full name "The Unlicense"; its metadata marks the license as OSI approved and FSF libre. npm package metadata uses SPDX license expressions in the `license` field, so `Unlicense` is the appropriate package string.
+
+## Implemented
+
+- Added root `LICENSE` with the canonical Unlicense text.
+- Added `testapp/LICENSE` with the same text.
+- Removed root `LICENSE_MIT` and `LICENSE_APACHE`.
+- Removed `testapp/LICENSE-MIT` and `testapp/LICENSE-APACHE`.
+- Updated `Cargo.toml` to `license = "Unlicense"` and version `0.1.2`.
+- Updated `Cargo.lock` for the new crate version.
+- Updated README license badge and license section.
+- Updated `testapp/package.json` and `testapp/package-lock.json` to `Unlicense`.
+- Added `tests/license_metadata.rs` to assert the expected license metadata and absence of old license markers.
+- Removed the auto-generated `.gitkeep` placeholder from the draft PR.
+
+## Solution Plan for Similar Repositories
+
+- Treat license changes as release metadata changes, not only documentation edits.
+- Use the SPDX identifier in package manager metadata.
+- Keep one canonical license file at the package root whenever possible.
+- Add a lightweight test or lint that scans maintained metadata files for expected license values.
+- Verify generated package output with `wasm-pack build` and `npm pack --dry-run` so published artifacts include the corrected license.
+
+## Verification
+
+Local verification completed successfully:
+
+- `cargo fmt --all -- --check`
+- `cargo check --locked --tests --all-features`
+- `cargo test --locked --lib --target "$(rustc -vV | sed -n 's/^host: //p')"`
+- `cargo test --locked --test license_metadata`
+- `cargo clippy --locked --tests --all-features -- -D warnings`
+- `wasm-pack build --release --target bundler --out-dir pkg`
+- `wasm-pack test --node`
+- `npm pack --dry-run` from `pkg/`
+
+The generated npm package metadata was confirmed as `doublets-web@0.1.2` with `license: Unlicense`, and the dry-run tarball includes a single `LICENSE` file. Logs are saved under `logs/`.
