Relicenses Wickra from PolyForm Noncommercial 1.0.0 to the dual, OSI-approved **MIT OR Apache-2.0** (the de-facto Rust convention). Wickra becomes permissive, commercial-use-permitted open source; users may choose either license.
## Changes
- Replace `LICENSE` (PolyForm) with `LICENSE-MIT` + `LICENSE-APACHE` (full texts).
- Cargo: workspace `license = "MIT OR Apache-2.0"` (SPDX) + all 7 sub-crates switched from `license-file.workspace` to `license.workspace`.
- `deny.toml`: drop PolyForm from the allowlist.
- Python: `pyproject.toml` PEP 639 SPDX expression; remove the non-commercial classifier (verified: sdist metadata emits `License-Expression: MIT OR Apache-2.0`).
- Node: `package.json`, the 6 platform manifests and both lockfiles.
- README + Python/Node/WASM binding READMEs, CONTRIBUTING, CITATION.cff, PR template, and the WASM `pkg.license` step in `release.yml`.
- SECURITY.md: refresh supported versions 0.1.x -> 0.4.x.
- CHANGELOG: note the relicense under [Unreleased].
## Notes
- No code changes; metadata/text only. `cargo build` and `cargo deny check licenses` pass locally.
- GitHub will auto-detect "MIT, Apache-2.0" once this lands (currently NOASSERTION).
- Matching downstream changes (org `.github` profile, webpage, docs) are in separate PRs; merge those together with the relicense release so the live sites and org profile do not claim MIT before the packages do.
Now that the wickra.org catch-all mailbox exists, move the project contact +
package-author email off the personal gmail to support@wickra.org across all
surfaces: CODE_OF_CONDUCT, SECURITY, CITATION.cff, Cargo.toml, the npm + PyPI
author fields, the release.yml npm author, and repo-metadata.toml. (The
package-author changes take effect on the next published release.)
repo-metadata.toml's [audit].forbidden still pins kingchencp@gmail.com (the
private commit email) as a banned substring — unchanged.
Also remove the FUNDING.yml custom "https://wickra.org/sponsor" entry: that
page 404s, so the Sponsor button linked to a dead URL. The GitHub Sponsors
entry (github: [kingchenc]) stays.
Five governance + onboarding files that collectively close the
"no high-level documentation outside of README" gap.
- ARCHITECTURE.md: workspace layout, Indicator trait contract,
per-indicator file conventions, numerical-stability notes,
cross-crate flow diagram, navigation cheatsheet, deliberate
non-goals, performance characteristics, stability commitments.
- ROADMAP.md: north star, 0.3 / 0.4 / 0.5 release windows,
indicator-wishlist intake rules, explicit non-goals, versioning policy.
- CITATION.cff: GitHub-renders as "Cite this repository" button;
enables academic adoption.
- .github/FUNDING.yml: surfaces Sponsor button on the repo page.
- .editorconfig: normalises indent/EOL across IDEs (Rust/Python 4 spaces,
JS/TS/JSON/YAML/MD 2 spaces, Makefile tabs).
Touches no Rust source, no CI workflows, no behaviour. Additive only.
URLs in ROADMAP/CITATION already reference the post-transfer
`wickra-lib/wickra` org so the files stay valid once the org migration
in PR #59 lands; merge this PR only after #59 to keep main consistent.
