⛔ Merged by the maintainer at the Tier H sitting, 2026-10-26 09:00Z (北京 17:00) — not before

This PR is Tier H by size (the whole objectui tree, ~2.6 M lines) and is the first of four merged in order at the sitting: this PR → 4a #25745 → PR B (objectstack#25697 item 6) → 4b PR 2 #25712, then the required-checks change (step 6). It stays draft until the seat says it is green; the seat never enqueues it. Reviewers: the GOVERNED_APPROVERS, requested when it leaves draft.

What this PR is

objectui (objectstack-ai/objectui) becomes the ui/ workspace of this repository, per the maintainer's D1 ruling (objectstack#25677: one repository, one fixed version group, the objectui repository archived as a migration notice).

1. git subtree add --prefix=ui of objectui main at its frozen tip 9e1fe032866965c7cb0460cff2b6af09350236b7 (objectui#13545, the final .objectstack-sha pin, pointing at objectstack 5e7cf63e71). objectui main is frozen since 2026-10-25 15:40Z (freeze notice: objectstack#25752); nothing lands there after that commit. History is kept (no squash).
2. Root workspace file. pnpm v10 reads overrides and patchedDependencies from pnpm-workspace.yaml only, so objectui's pnpm field moves there: the qs / shell-quote / tmp / uuid floors, the single react line (19.3.0), the @radix-ui/react-focus-scope@1.1.16 patch; the react-router override narrows to the 8.x line it fixes (objectui's react-router-dom 7.18 pins a 7.x react-router with no fixed version to force).
3. Adaptation series (objectstack#25803, card J) — one commit per gate or concern, each named in its message. Drop 1: every @objectstack/* range in the 32 ui manifests becomes workspace:^; ui/ stops being a workspace root of its own (nested pnpm-workspace.yaml deleted, pnpm field and preinstall pin check removed, turbo.json parked as turbo.objectui.json); the ui root manifest drops its turbo-recursive scripts; scripts/ui-import/splice-lockfile.mjs carries objectui's lockfile resolutions into the merged lock. Drop 2 (root gates, ledgers, eslint ignore, skills move, the K1 scoping of check:published-files) follows in this PR before it leaves draft; the list is in /mnt/project-files/d1-merge/out/cutover-adaptation/SERIES.md and will be mirrored here.
4. One lockfile. ui/pnpm-lock.yaml is removed; the root lock is objectui's resolutions spliced in (moved 0 against objectui's own lock at the splice), reconciled twice with pnpm install --lockfile-only, then pnpm dedupe; pnpm install --frozen-lockfile and pnpm dedupe --check exit 0. ai 7.0.118 and @ai-sdk/react 4.0.121 hold one copy each.

What this PR does not do

• It does not touch .github/workflows/**, AGENTS.md, docs/adr/** or CODEOWNERS: the pin-gate retirement is PR B, the release lane is 4a release(ui-merge): one release lane for both scopes — @object-ui joins the fixed group, @objectstack/console builds from ui/apps/console, the objectui pin is deleted (#25711) #25745, the workflow port is 4b PR 2 tooling(ui-merge): governance in-repo — liveness evidence and spec tests stop citing objectui by commit, one sdui-parser, AGENTS.md / pm scripts drop objectui#, ui/AGENTS.md nests, 18 governance workflows merged or retired (parent #25677, 4b/6) #25712, the governance for ui/ landed in tooling(pm): dispatch-gates git maxBuffer for the merged tree; register matchers proven on the nested ui/ rows (4b PR 1, inert) #25732.
• It does not remove the packages/console pin field or its build switch (sub-issue 4).
• It does not conform the 39 @object-ui manifests to check:published-files (maintainer ruling K1: the gate is scoped off ui/ here; aftercare objectstack#25753).

Accepted red classes (procedure #25752, "Accepted red classes") and the bill

Anything red on this PR is read against /mnt/project-files/d1-merge/out/5-cutover-bill-notes.md (items 1–36). A red that is not on the bill stops the sitting until it is ruled.

Verification

(filled by the seat before the PR leaves draft: the CI run, the local gate sweep, the lock verdicts and sha, the git am acceptance of the series.)
