2026-09-26 — Final governance cleanup

Goal and scope

Close the documentation/governance follow-up after deterministic Ranking Feature Contract Slice 1 qualification, repository hardening and its progress record. This session changes no planner/ranking semantics, CPIR, REST behavior, execution/authorization boundary, dependency or version authority. It does not implement Slice 2 or ML and creates no release or tag.

Branch protection status

At starting main 35a7cf9b949041da54cf68409a8650c49fceda37, GitHub initially reported protected: false and no active repository rulesets. During PR #12 the maintainer configured active repository ruleset main qualification for the default branch. The verified rules require a pull request, zero approvals, review-thread resolution and strict successful status checks for all 15 qualification gates; deletion and non-fast-forward updates are blocked. bypass_actors is empty and current_user_can_bypass is never. There is no merge-queue, linear-history, signed-commit or required-deployment rule. Documentation Pages and Traffic Stats are not required checks. The connected integration still receives 403 Resource not accessible by integration for the legacy branch-protection endpoint, and no repository-setting change was made by this session.

Qualification status alignment

The maintainer-confirmed current state after separate independent review is that deterministic Slice 1 has completed Math and Security qualification. The older dated implementation/progress records are not rewritten because their pre-qualification statements were accurate when recorded. This status correction changes no Ranking Feature Contract or planner/ranking semantics.

Governance/documentation corrections

  • Narrow the README badge policy so GitHub-native Repository Traffic Views/Clones may remain for repository transparency/project monitoring only under immutable-SHA, least-privilege, secret-scoping, no-extra-analytics and no-personal-profile constraints.
  • Preserve the existing hardened Traffic Stats workflow and badges; do not broaden the exception to generic visit counters or user tracking.
  • Record repository hardening in the Unreleased software changelog without implying a release.
  • Refresh the roadmap to the 2026-09-26 authority/status state and identify Slice 2 only as future architecture/contract work.

Verification

The documentation PR is subject to the repository's existing independent CI gates. This record does not pre-claim a local or remote PASS result; actual executed results are reported from the PR and final merged commit.
