* fix(#4458): reuse detectSubRepos for new-project.md's sub-repo detection new-project.md's Step 5.1 (Sub-Repo Detection) ran its own bash predicate: find . -maxdepth 1 -type d -not -name ".*" -not -name "node_modules" \ -exec test -d "{}/.git" \; -print `test -d` requires .git to be a DIRECTORY. A linked git worktree's .git is a FILE (a `gitdir: <path>` pointer), so this predicate silently excluded valid linked-worktree children while still finding ordinary clones. src/core-utils.cts's detectSubRepos(cwd) already handles this correctly (fs.existsSync, type-agnostic) but had zero callers anywhere in the codebase -- orphaned logic the workflow never actually used, despite duplicating a narrower version of the same check inline. Wired detectSubRepos into cmdInitNewProject's JSON output as a new sub_repos_detected field (matching the file's existing pattern of similar directory-scan-derived fields like has_existing_code/ is_brownfield/has_codebase_map) and replaced the workflow's raw find fence with a gsd_run query init.new-project call reading that field -- removing the duplicate, narrower detection logic entirely rather than patching it in place, per the issue's own "reuse a central policy" framing. Added the missing .git-as-FILE test case to the existing tests/core-utils.test.cjs detectSubRepos coverage (proving the helper was already correct -- the defect was entirely in the unwired workflow predicate) plus CLI-level end-to-end coverage in tests/init-manager.test.cjs using a REAL `git worktree add` fixture, matching the issue's own reproduction steps, alongside an ordinary child-clone case and a non-repository-directory negative case. Refreshed tests/fixtures/compact-content-benchmark-baseline.json (gsd-test caught the drift from new-project.md's byte-count change; the benchmark script itself always exits 0 -- report, not gate -- but the wrapper test enforces the committed baseline stays in sync). Emitted-Drift-Ack-Growth: new-project.md — #4458 replaces the raw find predicate in Step 5.1 with a gsd_run query call reading the new sub_repos_detected field, net +140 bytes Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * docs(#4458): backfill changeset PR number pr: 0 -> pr: 4548 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4458): bound the new git worktree add spawn with a named timeout CI's lint-tests caught two ESLint findings my local gsd-test run couldn't see (gsd-test's matrix doesn't run npm run lint:ci -- same gap already observed on #4456's PR): - local/no-unbounded-spawn: the new execFileSync('git', ['worktree', 'add', ...]) call had no timeout, an indefinite-hang risk. - local/no-adhoc-timeout-literal: my first fix (a bare `timeout: 15_000` literal) was itself flagged -- two independent hardcoded copies of a guessed timeout can silently drift or collide (this repo hit exactly that on 2026-09-06, PR #4428). Fixed by importing GIT_FIXTURE_TIMEOUT_MS from tests/helpers/timeouts.cjs -- `git worktree add` checks out files into a new working tree, the same "construction" weight class as init/config/add/commit that constant already covers, not plain plumbing (GIT_TIMEOUT_MS's class). Verified via `npm run lint` directly (clean) before re-running gsd-test. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4458): reduce redundant git subprocess overhead in new tests CI's full-test Windows shard 2/3 failed: chunk 1/9 (306 files) exceeded its internal 600s budget and was force-killed, with an unrelated file (codex-config.test.cjs) in flight at the moment of the kill -- meaning the chunk's AGGREGATE runtime, not any single hang, blew the budget. This PR's own three new tests each independently called createTempGitProject() (git init + a commit), and one of them also runs git worktree add -- real subprocess spawns, each Defender-scanned on Windows CI (tests/helpers/timeouts.cjs's own documented rationale for why Windows spawn classes get generous budgets). That's a genuine, quantifiable overhead addition to the exact chunk that timed out, not something to wave off as unrelated flake without checking. Two of the three tests never actually needed a real git repo -- detectSubRepos only inspects a CHILD directory's own .git, never the root's git state, and the existing SUBCOMMANDS loop earlier in this same file already proves `init new-project` succeeds against a plain, non-git createTempProject() fixture. Switched those two tests to the lighter fixture, leaving only the one test that genuinely needs a real repo (git worktree add requires one) on createTempGitProject().
