+# IAB Agentic Audiences (DRAFT, 2026-01)
+
+Vendored subset of the IAB Tech Lab Agentic Audiences specification, used by
+the buyer's Audience Planner agent for resolving Agentic audience references
+(embedding-based dynamic audiences).
+
+## Source
+
+- **Upstream:** https://github.com/IABTechLab/agentic-audiences
+- **Version:** draft-2026-01 (last upstream update 2026-01-28)
+- **Status:** DRAFT
+- **Fetched at:** 2026-04-25T19:27:21Z
+
+## What is vendored
+
+Only the subset relevant to grounding the wire format used by the buyer:
+
+```
+spec/
+  README.md                                Project overview + naming history (UCP -> Agentic Audiences)
+  LICENSE                                  CC-BY 4.0 (spec text)
+  LICENSE-APACHE                           Apache-2.0 (reference implementations)
+  specs/
+    roadmap.md                             Spec roadmap (placeholder upstream as of fetch)
+    v1.0/
+      embedding-exchange.md                Wire format for embedding exchange
+      embedding-taxonomy.md                Embedding taxonomy / signal types
+      examples/
+        buyer_agent_request.json           Example buyer-side payload (placeholder upstream)
+        embedding_update.json              Example embedding update payload
+        seller_agent_response.json         Example seller-side response (placeholder upstream)
+      schema/
+        agent_interface.schema.json        Agent interface JSON Schema (placeholder upstream)
+        embedding_format.schema.json       Embedding format JSON Schema
+```
+
+Files marked "placeholder upstream" are 0 bytes in the source repository at
+the time of vendoring. They are kept as empty files here to preserve the
+spec layout; they will be populated when the upstream repo fills them in.
+
+The full upstream repo also contains `prebid-module/`, `src/`, `community/`,
+and `catalog-info.yaml` -- those are reference implementations and not
+required to ground the wire format, so they are not vendored.
+
+## License
+
+The Agentic Audiences project ships under **two** licenses:
+
+- **CC-BY 4.0** for the specification text (`spec/LICENSE`).
+- **Apache 2.0** for reference implementations (`spec/LICENSE-APACHE`).
+
+> Copyright (c) 2025 LiveRamp Holdings, Inc.
+> Spec content distributed under CC-BY 4.0.
+> Reference implementations distributed under Apache-2.0.
+
+This vendored copy is unmodified. Any downstream use must preserve both
+attributions where applicable.
+
+## Naming note
+
+Agentic Audiences was previously known as the **User Context Protocol (UCP)**.
+The buyer's `ucp_*` modules implement this spec; see
+`docs/proposals/AUDIENCE_PLANNER_3TYPE_EXTENSION_2026-04-25.md` Section 5.6
+for the rename rationale.
+
+## Update process
+
+This subset is vendored, not fetched at runtime. To upgrade:
+
+1. Re-fetch the files listed above from the upstream repo.
+2. Recompute the composite hash and per-file map recorded in
+   `data/taxonomies/taxonomies.lock.json` under the `agentic` key by
+   running the canonical helper script:
+
+   ```bash
+   # from the buyer repo root
+   python3 scripts/hash_taxonomies.py            # print computed values to stdout
+   python3 scripts/hash_taxonomies.py --write    # rewrite taxonomies.lock.json in place
+   python3 scripts/hash_taxonomies.py --check    # verify lock matches the on-disk spec (CI)
+   ```
+
+   The script implements the same composite-hash algorithm used by the
+   seller (`sha256(sorted lines of '<relpath>\t<sha256>\n')`) so cross-
+   repo drift detection compares apples to apples. Per-file sha256
+   entries are emitted under `agentic.files` so a refresher can see
+   exactly which file changed when the composite changes.
+3. Update the `Fetched at` timestamp here and the `version` field in
+   the lock file (e.g., `draft-2026-01` -> `draft-2026-04`).
+4. Re-run any wire-format validation tests; the spec is DRAFT and shapes
+   may change between fetches.

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
