## ConfigKit Applicability
ConfigKit's selected grant is LGPL-3.0-or-later, recorded in
[COPYRIGHT](../../COPYRIGHT), with the complete LGPLv3 and incorporated GPLv3
texts in [LICENSE](../../LICENSE). Adoption does not change that grant.

## Purpose And Scope
This policy defines project licensing conventions and a repeatable House Format
for upstream attribution and license notices. It covers the project's own code
and upstream components incorporated into or distributed with the project,
including relevant transitive dependencies and
copied code or assets. Treatment follows the component's terms and actual use,
rather than its classification as a direct dependency.
and upstream components incorporated into or distributed with the application
or library, including relevant transitive dependencies and copied code,
documentation, or assets.
Determine treatment from the component's terms and actual use.
Consulting development guidance or using tooling alone does not require an
attribution entry. Copying or adapting documentation for inclusion in the
repository is different: preserve its applicable attribution and license terms.
A material's role as development guidance does not exempt copied documents.
Apply any express permissions for attribution-free reuse of example formatting.
The baseline is a publicly available source repository with releases published
alongside it. The format is independent of language, forge, and build system.

## Upstream Attribution House Format
Each component entry has five fields:
Begin `docs/oss/attribution.md` with `# Open Source Attribution Notices`,
followed directly by component entries. These comprise the complete document.
1. **Project name**, normally as the entry heading.
Each entry presents these five fields in order, with blank lines between them:
1. **Project name** as a level-two heading. An optional identification paragraph
may follow, such as `Selected module: MODULE at VERSION.` with the module and
version in backticks. For copied documentation, a concise `Material:` sentence
may identify the affected files and whether they were adapted or copied
without modification. A factual qualifier such as `(transitive dependency)`
is permitted. Limit optional identification prose to factual component and
material scope.
2. **Upstream copyright statement or statements**, preserving their wording.
3. **SPDX license identifier or expression**, when applicable.
4. **License and notice links**, covering the applicable standard texts and
upstream project-specific material.
5. **Source repository link**, identifying the source corresponding to the
imported version.
Put multiple statements in separate paragraphs. Include this field when the
selected upstream source supplies an applicable statement; otherwise, omit it.
3. **SPDX license identifier or expression**, when applicable, using
`SPDX-License-Identifier: EXPRESSION`.
4. **License and notice links**, beginning `License and notices:`, separated
by ` | `, and ending with a period. Label local standard texts by license
name, such as `MIT` or `Apache 2.0`. Label upstream files by their actual
filenames, such as `COPYRIGHT`, `LICENSE`, `NOTICE`, or `PATENTS`.
5. **Source repository link**, rendered exactly as `[Source](COMMIT_URL).`.
The [go-yaml entry](../oss/attribution.md#go-yaml-v4) demonstrates this format
with the pinned module's actual statements and links.
Use the upstream [attribution example](https://gitea.maximumdirect.net/eric/policy/src/commit/d84a38ebab26f048cafbe59a2246700c35d29843/examples/licensing/attribution.md)

The example illustrates omitted fields and multiple copyrights and licenses.
Replace the uppercase placeholders and illustrative URLs with actual component
information. Local license links are relative to the destination
`docs/oss/attribution.md`; copy the applicable texts into its `licenses/`
directory. Do not copy example entries for components the project does not use.
These are five fields, not a line limit. Include multiple statements and links
where needed. Omit the SPDX field when no applicable identifier exists; identify
nonstandard terms accurately through the linked text. Preserve licensing
alternatives and exceptions, and record a selected option when relevant. Do not
invent an identifier or silently resolve an unsettled licensing choice.

Keep entries factual. Do not add agent-authored explanations of license
expressions, file-level license scope, research performed, retained source
notices, or compliance conclusions. Avoid filler such as "none is invented
here" and embellished link labels such as "upstream LICENSE", "additional
patent grant", or "at the imported commit". Preserve actual required upstream
content; this rule excludes editorial additions, not required notices. Policy
interpretation and exception reasoning belong in the adopted OSS policy or an
appropriate decision record, not the attribution document.
## License Texts And Upstream Links
Link standard license texts to their local copies. Link project-specific
notices to the upstream copies instead of storing them locally. Every upstream
repository or notice link must identify the exact commit corresponding to the
notices to their upstream copies. Every upstream repository or notice link must
identify the exact commit corresponding to the
imported version, including the selected source revision for copied material.
Do not use moving branches or version tags as substitutes for that commit.
