Update MCP gateway GitHub guard terminology

[Claude]

Updates MCP gateway GitHub guard configuration terminology for integrity levels:

• reader → unapproved
• writer → approved
• merged and none remain unchanged

The new integrity hierarchy is: merged > approved > unapproved > none

Integrity Level Definitions

Integrity levels are determined based on the combination of the author_association field associated with GitHub objects (issues, pull requests, comments, etc.) and whether an object is reachable from the main branch:

Level	Criteria
merged	Objects reachable from the main branch (regardless of authorship)
approved	Objects with author_association of OWNER, MEMBER, or COLLABORATOR
unapproved	Objects with author_association of CONTRIBUTOR or FIRST_TIME_CONTRIBUTOR
none	Objects with author_association of FIRST_TIMER or NONE

How it works:

• Merged content has the highest integrity because it has been reviewed and merged into the main branch
• Approved contributors (owners, members, collaborators) have established trust relationships with the repository
• Unapproved contributors have made contributions but lack formal repository access
• None level includes first-time interactions and users with no prior contribution history

Changes

Code Updates

• Updated GitHubIntegrityLevel constants in pkg/workflow/tools_types.go
• Updated validation error messages in pkg/workflow/tools_validation.go
• Updated test cases in pkg/workflow/tools_validation_test.go

Schema Updates

• Updated enum values in pkg/parser/schemas/main_workflow_schema.json

Documentation Updates

• Updated scratchpad/guard-policies-specification.md with detailed integrity level explanations
• Updated docs/src/content/docs/reference/github-tools.md with integrity level definitions table
• Updated docs/src/content/docs/reference/frontmatter-full.md
• Updated scratchpad/dev.md with integrity level criteria

Testing

• ✅ All tests passing (including TestValidateGitHubGuardPolicy)
• ✅ Code formatted with make fmt
• ✅ Binary builds successfully
• ✅ Workflows recompiled

Notes

The key name was already min-integrity (not integrity), so no changes were needed there.

@claude[agent] add an explanation to documentaiton about the meaning of these levels

integrity levels are based on the combination of the author_association field associated with github objects and whether an object is reachable from the main branch.

objects reachable from the main branch are given "merged" integrity regardless of authorship.

objects with author_association of OWNER, MEMBER, COLLABORATOR are given "approved" integrity

objects with author_association of CONTRIBUTOR, FIRST_TIME_CONTRIBUTOR are given "unapproved" integirty

objects with FIRST_TIME_CONTRIBUTOR, FIRST_TIMER, NONE are given "none" integrity

Added detailed explanations of integrity level meanings to the documentation in commit 47d441c. The documentation now includes:

• How integrity levels are determined based on author_association fields and main branch reachability
• Clear criteria table showing which author associations map to each level
• Explanation that merged content has highest integrity, followed by approved, unapproved, and none levels

Updated in docs/src/content/docs/reference/github-tools.md, scratchpad/guard-policies-specification.md, and scratchpad/dev.md.

Pull request overview

This PR updates the MCP gateway GitHub guard configuration terminology by renaming integrity level constants. The previous reader and writer values are replaced with unapproved and approved respectively, with none and merged being pre-existing constants that remain valid. The new hierarchy makes the intent clearer by naming levels based on contributor trust status rather than permission metaphors.

Changes:

• Renamed GitHubIntegrityReader/"reader" → GitHubIntegrityUnapproved/"unapproved" and GitHubIntegrityWriter/"writer" → GitHubIntegrityApproved/"approved" in Go types, validation, and tests
• Updated the min-integrity JSON schema enum from ["reader", "writer", "maintainer", "admin"] to ["none", "unapproved", "approved", "merged"]
• Updated documentation and scratchpad files with new terminology and detailed integrity level definitions

The PR description states "reader → unapproved, writer → approved, merged and none remain unchanged," but the previous schema enum was ["reader", "writer", "maintainer", "admin"]. The values merged and none were not present in the old schema at all, and maintainer and admin are removed with no documented mapping. The PR description is inaccurate regarding what was changed in the schema — this discrepancy may be confusing to reviewers and contributors trying to understand the migration path.

[Copilot]

The integration test file pkg/workflow/guard_policy_experimental_warning_test.go (not included in this PR) still uses the old reader and writer integrity level values at lines 32 and 80. After this PR's changes, those values are no longer valid, which will cause the integration tests TestGuardPolicyExperimentalWarning to fail — the test cases that use these values expect compilation to succeed, but the updated validation will now return a validation error for both. Those test cases need to be updated to use unapproved and approved respectively.
