+# Task: Land official project scaffold plugin on main
+
+## Identity
+
+- Task ID: 20260904-project-scaffold-main-merge-e7b4c291
+- Mode: Integration
+- Branch: main
+- Worktree: D:\Datas\OthersProjects\makelore
+- Base commit: 336e0bb0caf24537b7b0f350aba3e04a37f5544c
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Fast-forward the verified integration commit `b92e7ba5bbde186626d93787ca358fbf4c2523a3` onto local `main`.
+- Record final default-branch landing evidence while preserving the three explicitly adopted historical task documents unchanged and uncommitted.
+
+## Intent And Constraints
+
+- Preserve the accepted official bundled-plugin boundary: only the fixed code-owned resource root may execute `scaffold.mjs`; downloadable Marketplace artifacts continue to reject scripts.
+- Preserve normal ancestry and do not package, publish, deploy, push, or alter the adopted historical task documents.
+
+## Outcome
+
+- Fast-forwarded local `main` from `336e0bb0caf24537b7b0f350aba3e04a37f5544c` to verified integration head `b92e7ba5bbde186626d93787ca358fbf4c2523a3`.
+- Local `main` now contains the unified `interactive_ai_app` type and the official bundled Marketplace Plugin `makelore.project-scaffold`, including its Skill, templates, publication guidance, and `scaffold.mjs`.
+- Preserved the three explicitly adopted historical task documents byte-for-byte and left them uncommitted.
+- Excluded the completed source integration task record from the final default-branch tree; it remains reachable on its preserved source branch and commit.
+
+## Verification
+
+- The fast-forward completed without conflicts and `b92e7ba5bbde186626d93787ca358fbf4c2523a3` is an ancestor of local `main`.
+- The exact landed integration head had already passed Plugin and Skill validators, 88 focused Vitest tests, 12 scaffold Node tests, TypeScript typecheck, Git whitespace checks, and project-document gates.
+- The task-aware drift check passed while confirming all adopted historical documents remained unchanged.
+
+## Follow-ups
+
+- Packaging, installed-client smoke, live Marketplace publication, deployment, and remote push remain separate authorized operations.
+
+## Promotion Candidates
+
+- None. This task landed the already accepted and verified integration result.
