Complete Connector Semantic Affordances

1. Manifest Semantics

• Audit supported connector manifests for readable natural-language fields missing query.search.
• Add missing lexical and semantic declarations for owner-visible natural-language fields.
• Add x_pdpp_role declarations across supported connector streams.
• Add manifest-honesty tests for search affordance coverage and role coverage.

2. Schema Projection

• Project schema.properties[field].x_pdpp_role into reference field_capabilities[field].role.
• Preserve role flags in compact schema output.
• Preserve role flags in MCP schema compaction.
• Update focused compact formatter tests.

3. Authoring Guidance

• Add prior-art research to the corpus.
• Add or update the connector authoring guide with a short checklist, examples, and anti-patterns.
• Link the guide from the relevant contributor entry point.

4. Validation

• Run new manifest-honesty tests.
• Run polyfill connector typecheck.
• Run existing manifest-honesty tests.
• Run package-level polyfill connector tests with dependencies installed. Full suite currently reaches unrelated iMessage harness failure.
• Run MCP schema-token tests with package dependencies installed.
• Run MCP server test suite.
• Run reference implementation typecheck.
• Run direct reference compact field formatter check.
• Run openspec validate complete-connector-semantic-affordances --strict.
• Run git diff --check.
