+Build Dashboards and Quality Gates
+==================================
+
+Use this guide in repositories that consume docs-as-code as a Bazel
+dependency.
+
+Goals:
+
+1. Publish traceability dashboards from repository needs.
+2. Export machine-readable metrics.
+3. Enforce CI thresholds with ``traceability_gate``.
+
+What You Get
+------------
+
+With the ``docs(...)`` macro and ``score_metamodel`` extension enabled, your
+repository can:
+
+- build an HTML dashboard from its own Sphinx needs,
+- include external needs from other repositories when desired,
+- export ``needs.json`` and ``metrics.json`` for machine-readable reporting,
+- gate CI on traceability thresholds via ``traceability_gate``.
+
+Typical Setup
+-------------
+
+For details, see :ref:`setup`.
+
+Minimal Configuration Example
+-----------------------------
+
+In ``docs/conf.py``:
+
+.. code-block:: python
+
+   score_metamodel_requirement_types = "feat_req,comp_req,aou_req"
+   score_metamodel_include_external_needs = False
+
+Use ``score_metamodel_include_external_needs = True`` (aggregate_traceability_across_dependencies)
+only in repositories that intentionally aggregate requirements across module dependencies, such as
+integration repositories. Use ``False`` for module repositories to gate only on local traceability.
+
+Building the Dashboard
+----------------------
+
+After building/running any docs command (i.e. ``bazel build //:needs_json`` or ``bazel run //:docs_verify`` are the fastest):
+
+The documentation build writes ``metrics.json`` via ``score_metamodel``, and the ``needs_json`` artifact contains:
+
+- ``bazel-bin/needs_json/_build/needs/needs.json``
+- ``bazel-bin/needs_json/_build/needs/metrics.json``
+
+The dashboard charts and the CI gate both use the same computed metrics.
+
+Inputs for Linkage Metrics
+--------------------------
+
+To get meaningful dashboard and gate values, consumer repositories typically
+need three inputs:
+
+1. Requirement and architecture needs in the documentation itself.
+2. Source code references via :doc:`source_to_doc_links`.
+3. Test metadata via :doc:`test_to_doc_links`.
+
+If one of those inputs is missing, the related chart or gate metric will remain
+empty or low.
+
+Choosing Local vs Aggregated Views
+----------------------------------
+
+There are two common modes:
+
+**Module repository**
+
+- Set ``score_metamodel_include_external_needs = False``.
+- Gate only on the needs owned by the repository itself.
+- Use this for per-module implementation progress and traceability.
+
+**Integration repository**
+
+- Set ``score_metamodel_include_external_needs = True``.
+- Aggregate requirements across module dependencies when that is the intended
+  repository purpose.
+- Use this for system or integration-level dashboards.
+
+CI Quality Gate
+---------------
+
+After building ``//:needs_json``, run the gate on the exported metrics:
+
+.. code-block:: bash
+
+   bazel run //:docs && \
+   bazel run //:traceability_gate -- \
+      --metrics-json bazel-bin/needs_json/_build/needs/metrics.json \
+      --min-req-code 70 \
+      --min-req-test 70 \
+      --min-req-fully-linked 60 \
+      --min-tests-linked 70
+
+In CI, wire targets through Bazel dependencies so test execution and
+``needs_json`` generation happen before the gate target.
+
+In larger repositories, define a dedicated wrapper target for your standard
+gate thresholds so CI calls a single Bazel target.
+
+Useful flags:
+
+- ``--require-all-links`` for strict 100 percent gating
+
+Recommended Rollout
+-------------------
+
+For a new consumer repository:
+
+1. Start with local-only metrics.
+2. Enable ``scan_code`` and verify ``source_code_link`` coverage first.
+3. Add test metadata and verify ``testlink`` coverage.
+4. Introduce modest thresholds in CI.
+5. Raise thresholds over time as the repository matures.

+This page shows how the docs-as-code tooling covers process and tool
+requirements. It focuses on tooling capabilities offered to downstream
+repositories rather than on product-specific traceability inside those
+repositories.

+
+- :ref:`Tool Requirement Implementation and Links table <tooling_coverage_table_impl_links>`
+- :ref:`Process Requirement to Tool Requirement mapping table <tooling_coverage_table_process_mapping>`
+
+How To Read These Levels
+------------------------
+
+The overview pie combines implementation state and traceability evidence:
+
+- ``not implemented``:
+   requirement has ``implemented == NO``.
+- ``implemented but incomplete traceability``:
+   requirement has ``implemented == YES`` or ``implemented == PARTIAL``,
+   but is missing at least one traceability link (code link and/or test link).
+- ``fully linked``:
+   requirement has both ``source_code_link`` and ``testlink``.
 
-   type == 'tool_req' and implemented == 'NO'
-   type == 'tool_req' and testlink == '' and (implemented == 'YES' or implemented == 'PARTIAL')
-   type == 'tool_req' and testlink != '' and (implemented == 'YES' or implemented == 'PARTIAL')
+Implementation labels used on this page:
+
+- ``NO``: requirement is not implemented.
+- ``PARTIAL``: requirement is partly implemented.
+- ``YES``: requirement is implemented.
+
+Why multiple pies are shown:
+
+- ``Requirements with Codelinks`` shows requirement-to-implementation traceability.
+- ``Requirements with linked tests`` shows requirement-to-verification traceability.
+- ``Requirements fully linked`` is the strict roll-up (both links present).
+
+These are intentionally separate because they answer different diagnostics:
+missing code links, missing test links, or both.
