Quote inconsistency in frontmatter file_type field; standardize across all documentation files.
Line 10 uses single quotes: file_type: 'documentation', while other files use double quotes: file_type: "documentation". YAML accepts both, but consistency improves maintainability and may prevent schema validation issues if the validator is strict about quote style.
Standardize to double quotes across all documentation files (.github/agents/README.md, .github/README.md, .github/reporting/README.md, README.md, and docs/BRANDING.md) for consistency.
Apply this diff:
-file_type: 'documentation'
+file_type: "documentation"Alternatively, if double quotes are enforced by schema, ensure all files use them.

In docs/BRANDING.md around lines 10 to 24 the frontmatter uses single quotes for
file_type (file_type: 'documentation'); update this to use double quotes
(file_type: "documentation") to match the project's convention and the other
listed docs (.github/agents/README.md, .github/README.md,
.github/reporting/README.md, README.md). Make the same replacement in those
files if any still use single quotes, and re-run a quick search (e.g., grep) to
ensure all documentation frontmatter file_type fields consistently use double
quotes.

🧩 Analysis chain
Critical: Frontmatter validation error on root README.md blocks merge.
Pipeline validation fails on the file_type field with error: tag "file_type" must be string. This is a critical blocker for the root repository README.
Root documentation files are essential; validation must pass before merge. The error appears across all files in this PR, suggesting a systemic schema issue rather than a per-file problem.
Required action: Inspect the frontmatter schema definition (.github/automation/front-matter.schema.json or equivalent) to determine:
- Expected type for
file_typefield (string, array, object, or enum) - Any allowed values or patterns
- Whether the schema definition needs updating or the field values need correction
Use the verification script provided in .github/agents/README.md comment to inspect the schema.
I need to verify this critical validation error claim. Let me search the codebase for the schema definition and check the actual frontmatter:

Fix broken reference path in README.md frontmatter.
The reference path "AUTOMATION_GOVERNANCE.md" (line 26) should be "./.github/automation/AUTOMATION_GOVERNANCE.md" to correctly resolve to the actual file location. The file exists but the relative path in the frontmatter references section is incorrect.
🤖 Prompt for AI Agents
In README.md around lines 6 to 6, the frontmatter reference path is
incorrect—replace "AUTOMATION_GOVERNANCE.md" with the correct relative path
"./.github/automation/AUTOMATION_GOVERNANCE.md" so the frontmatter links resolve
to the actual file location.
