The smoke lane now drives a workspace task on builtin:coding-ideas-v2 from the
Ideas intake to `merged-done`, alongside the existing single-repository coverage.
6 files, 65 tests, 19/19 scenarios, 77.1s of the 90s budget.
Two fixture defects stood between the harness and that proof, both of the same
shape: a workspace task legitimately has NO task-level `branch` — each repository
owns one under `workspaceWorktrees[repo].branch`.
- The scripted merger was handed `task.branch ?? ""`, so it ran
`git merge --squash` on an empty ref ("merge: - not something we can merge"),
surfacing only as the generic "Workspace repository repo1 could not land".
- Resolving the branch at INSTALL time was still wrong: the merge is attempted in
the same turn as the first install, before acquisition has created any
per-repository worktree. The scripts now receive an async getter that reads the
live task when the merger actually runs, so ordering cannot make it stale.
This also corrects an earlier misattribution recorded in the previous commit: the
land failure was NOT a missing `repositoryScope`. A probe showed the scope
confirmed, the review evidence recorded, and `workspaceWorktrees.repo1.branch`
populated — the harness simply never passed that branch to the merger.
The workspace path is now measured, not inferred: plan, plan-review, parse,
verification, documentation-delivery, completion-summary, code review
("All 1 modified in-scope sub-repo(s) approved") and the per-repository land all
run, with `mergeDetails.mergeConfirmed` asserted on the persisted row.
