+# Commercial License Grants
+
+crosscheck-agent is released under the [PolyForm Noncommercial License 1.0.0](LICENSE).
+That license permits noncommercial use only — personal projects, research,
+hobby use, internal evaluation, and use by qualifying noncommercial
+organizations as defined in the PolyForm NC text.
+
+**Commercial use** — including but not limited to (a) selling the software
+or services that incorporate it, (b) embedding it in a commercial product,
+(c) using it in the course of for-profit operations beyond internal
+evaluation, or (d) operating it as a paid hosted service — requires a
+separate commercial license from the copyright holder, Frank Speiser
+(frank@metafide.io).
+
+The grants below are the only pre-existing commercial licenses for this
+software. All other commercial use requires an inquiry.
+
+---
+
+## VARDR Partners
+
+**Effective date:** 2026-05-29
+
+**Licensee:** VARDR Partners, and its wholly-owned subsidiaries
+(collectively, "VARDR").
+
+**Grant.** Subject to the terms of this section, the copyright holder
+grants VARDR a non-exclusive, worldwide, royalty-free license to use,
+copy, modify, and distribute the software for any purpose, including
+commercial purposes. This grant is in addition to (and not in lieu of)
+the rights VARDR has under the PolyForm Noncommercial License 1.0.0.
+
+**Sublicensing.** VARDR may sublicense the software to customers as part
+of a VARDR product or service, provided the end-customer's rights flow
+from VARDR's sublicense (not from the PolyForm NC text) and are no
+broader than VARDR's own commercial rights here.
+
+**Term.** This grant is **perpetual unless revoked** by the copyright
+holder.
+
+**Revocation.** The copyright holder may revoke this grant at any time,
+**with or without cause**, by either:
+
+  1. emailing written notice to a designated VARDR contact, or
+  2. removing or amending this section in a commit to this repository.
+
+Upon revocation, VARDR must **cease all commercial use** of the software
+within ninety (90) calendar days of the notice (or the commit, if revoked
+via repository). VARDR may continue any sublicenses already issued to
+end customers as of the revocation date for the remainder of those
+sublicenses' existing terms, provided VARDR does not issue new
+sublicenses after the revocation effective date. After the 90-day
+wind-down, VARDR retains only the noncommercial rights granted by the
+PolyForm Noncommercial License 1.0.0.
+
+**No warranty.** The "No Liability" disclaimer in the PolyForm
+Noncommercial License 1.0.0 applies to this commercial grant as well.
+The software is provided **as is**, without warranty or condition of
+any kind.
+
+**Severability.** If any provision of this grant is held unenforceable,
+the remaining provisions remain in effect.
+
+**Granted by:** Frank Speiser, copyright holder
+(frank@metafide.io)

+**frank@metafide.io** with the intended use, scope, and term. Commercial
+licenses are routinely available; this section will be updated when
+new grants are issued.
