DKF Development Modes — Increment 001: policy architecture foundation

[eybersjp]

Scope

Introduces a pure, inactive foundation for DKF Development Modes, based on v0.10.0 main and deliberately isolated from the still-draft v0.10.1 Live UI Preview PR #41.

Delivered

• Five developer-facing modes: Rapid, Balanced (default), Spec-Driven, Doc-Driven, Maintenance & Evolution.
• Maintenance as an existing-project context that inherits one of the four methodologies and requires repository audit.
• Explicit v1 machine-readable selection schema and strict runtime policy resolver.
• Profile defaults → discretionary custom policies → only-strengthening project overrides; field-level provenance.
• Non-configurable mandatory-control manifest, without modifying existing Autopilot autonomy or acceptance gates.
• Node regression suite MOD-001 through MOD-011, included in npm run release:validate.
• Architecture/ADR, acceptance specification, docs index, and repository memory.md.

Deliberately deferred

Initialization UI, CLI/persistence, recommendation engine and change history (002); actual Autopilot/documentation policy consumption (003–004); mode migration and end-to-end acceptance (005). No public package version change, tag, release, npm publication or runtime permission change.

Verification and acceptance checklist

• Ubuntu CI completed npm run release:validate (PASS).
• Windows CI completed npm run release:validate (PASS).
• Inspect actual diff and independently verify MOD-001–MOD-011.
• Confirm project override validation does not weaken existing controls.
• Reconcile/rebase against PR DKF v0.10.1: Live UI Preview & Visual Verification #41 after its own pending Product Owner acceptance; re-run CI on final merge base.
• Product Owner acceptance. Keep draft until all applicable gates are satisfied.

This draft does not claim local Antigravity/private consumer validation or final acceptance. Increment 001 contains no UI work requiring a browser preview.

GitHub Actions evidence — 27 September 2026

• CI run #36347881173: Ubuntu PASS; Windows PASS.
• New Increment 001 test suite: MOD-001–MOD-011, 11/11 PASS on both operating systems, confirmed in each job's release-validation logs.
• Diff audit: exactly eight expected paths, no edits to runtime/autopilot/ or runtime/orchestration/; package version unchanged.
• PR DKF v0.10.1: Live UI Preview & Visual Verification #41 has 88 changed files; overlap with this PR is limited to docs/SUMMARY.md and package.json. Reconcile these after PR DKF v0.10.1: Live UI Preview & Visual Verification #41 is accepted/merged; run CI again on the final merge base.

Decision: Automated checks PASS; keep draft for independent criterion review, Product Owner acceptance and base-branch reconciliation. No release or publication authorized.

This draft is being closed as a stale implementation branch, not rejected work. Its policy architecture is preserved at head ef3b118004a846ab9989dc41b995f5c8494d4064 and has been carried forward into Issue #50. The branch predates v0.11.0/v0.11.1 by 136 mainline commits and must not be merged directly. Reimplementation/reconciliation will start from current main, independently verify MOD-001–MOD-011, and preserve all mandatory reliability controls.
