# Source and license notes

Reviewed 2026-08-30. [Pinned behavioral reference](https://github.com/coreyhaines31/marketingskills/blob/e55de886fe7580ec75cdb7ded5092b33f7d4ed58/skills/ai-seo/SKILL.md) is from coreyhaines31/marketingskills commit e55de886fe7580ec75cdb7ded5092b33f7d4ed58, MIT license. No upstream wording, helper code or assets were copied.

All new helpers, fixtures, instructions and labs are original. Prompthon adaptations: the distinct Discover responsibility, course persistence, revision/readback behavior, synthetic classroom data, clear authorization and recheck limits. Social specifically reuses the existing repository package's `build_plan_settings` and `build_variant_overrides` functions, canonical models and Host operation shape; its legacy helper is preserved unchanged.

See the [shared source audit](../../course-support/references/source-audit.json). Local source verification of the Prompthon Web App is documented in Social's [canonical Host contract](../../prompthon-social-campaign-manager/references/canonical-host-contract.md); a checked-out source contract is not evidence of current production deployment.
