	 * Dry-runs stay synchronous and delegate to the same workspace abilities as the
	 * lower-level `workspace worktree cleanup*` commands until DB-backed cleanup
	 * plans land.
	 *
	 * ## OPTIONS
	 *
	 * <operation>
	 * : Cleanup operation. One of: <plan|apply|run|status|resume|cancel|evidence>.
	 *   Existing task-backed controls remain: <run|status|resume|cancel|evidence>.
	 *
	 * [<run-id>]

	 * ---
	 *
	 * [--dry-run]
	 * : Run the selected cleanup review synchronously through workspace abilities.
	 *
	 * [--force]
	 * : Pass force=true into the cleanup task params for modes that support it.
	 *
	 * [--include-artifacts]
	 * : For `plan --mode=retention`, include artifact cleanup rows. Retention
	 *   planning includes a full-workspace artifact inventory by default; this flag
	 *   remains accepted for explicitness and `--mode=artifacts` still creates an
	 *   artifact-only plan. `--mode=stale-worktrees` never includes artifacts unless
	 *   this flag is passed.
	 *
	 * [--older-than=<duration>]
	 * : Pass an age gate such as 7d or 24h into cleanup task params.
	 *
	 * [--top=<count>]
	 * : For `plan`, number of largest reclaimable paths to show in the upfront
	 *   summary. Defaults to 10.
	 *
	 * [--limit=<count>]
	 * : For DB-backed `apply` / `resume`, maximum pending rows to process in this
	 *   invocation (default 25, max 100). For `--mode=artifacts` pages, maximum
	 *   worktrees to scan; dry-run reviews scan this bounded page synchronously,
	 *   and apply runs freeze eligible candidates from the same bounded page.
	 *   Artifact page scans default to 100. Use 0 to disable the artifact scan cap
	 *   (combine with --exhaustive for a full audit).
	 *
	 * [--offset=<count>]
	 * : Pagination offset (0-indexed) for `--mode=artifacts` dry-run and apply
	 *   pages. Walk huge workspaces by feeding the previous response's
	 *   `pagination.next_offset` until `pagination.complete` is true.
	 *
	 * [--exhaustive]
	 * : For `--mode=artifacts --dry-run`, scan every worktree AND run per-worktree
	 *   git status / unpushed-commit safety probes. Slow on huge workspaces; use
	 *   sparingly for full audits.
	 *
	 * [--safety-probes]
	 * : For `--mode=artifacts --dry-run`, run the per-worktree git safety probes
	 *   without disabling the bounded scan. Useful when you want a small slice
	 *   audited with full safety information.
	 *
	 * [--verbose]
	 * : Include full diagnostic child job ID lists in task-backed cleanup status output.
	 *
	 * [--drain]
	 * : For `cleanup run`, drain the queued parent job, drain active child cleanup
	 *   jobs discovered from cleanup status, then print verified bytes reclaimed.
	 *
	 * [--format=<format>]
	 * : Output format.

	/**
	 * Manage workspace git worktrees.
	 *
	 * Worktrees let multiple agent sessions work on the same repo without
	 * stepping on each other. Each branch lives in its own directory at
	 * `<workspace>/<repo>@<branch-slug>`. Branch slashes become dashes in
	 * the slug (`fix/foo` → `fix-foo`).
	 *
	 * ## OPTIONS
	 *
	 * <operation>
	 * : Worktree operation: add, list, remove, prune, locks, cleanup, cleanup-artifacts,
	 *   bounded-cleanup-eligible-apply, emergency-cleanup, reconcile-metadata,
	 *   active-no-signal-report, active-no-signal-finalized-apply,
	 *   active-no-signal-equivalent-clean-apply,
	 *   active-no-signal-merged-apply, active-no-signal-remote-clean-apply,
	 *   refresh-context, finalize, mark-cleanup-eligible.
	 *
	 * [<repo>]
	 * : Primary repo name (required for add and remove). For refresh-context, finalize,
	 *   and mark-cleanup-eligible,
	 *   pass the full worktree handle (`<repo>@<branch-slug>`) here instead.
	 *
	 * [<branch>]
	 * : Branch name (required for add and remove).
	 *
	 * [--from=<ref>]
	 * : Base ref when creating a branch on add (default origin/HEAD).
	 *
	 * [--base=<ref>]
	 * : Alias for `--from=<ref>`.
	 *
	 * [--base-ref=<ref>]
	 * : Alias for `--from=<ref>`.
	 *
	 * [--base-branch=<branch>]
	 * : Convenience alias for branch-shaped bases. `--base-branch=main`
	 *   maps to `--from=origin/main`. Use `--from`, `--base`, or `--base-ref`
	 *   for exact refs.
	 *
	 * [--skip-context-injection]
	 * : Skip injecting the originating site's agent context into a new
	 *   worktree (applies to `add` only). Default behavior is to make the site's
	 *   composed AGENTS.md visible to OpenCode: symlink it into the worktree root
	 *   when no repo-owned AGENTS.md exists, otherwise add it via local OpenCode
	 *   instructions so both files load. Also writes `.claude/CLAUDE.local.md`
	 *   containing the site's MEMORY.md / USER.md / RULES.md snapshot, and adds
	 *   injected paths to the repository's `info/exclude`. The ability-level input
	 *   is `inject_context=false`; this flag is the CLI shorthand.
	 *
	 * [--skip-bootstrap]
	 * : Skip the default bootstrap pass (applies to `add` only). By default,
	 *   `worktree add` runs detected setup so the checkout is immediately
	 *   test/build-ready:
	 *     - git submodule update --init --recursive (if .gitmodules)
	 *     - pnpm/bun/yarn/npm install (based on root or one-level nested lockfiles)
	 *     - composer install --no-interaction (based on root or one-level nested composer.lock)
	 *   Each step is skipped gracefully when its trigger file or tool is
	 *   missing. Pass `--skip-bootstrap` to create a bare checkout for pure
	 *   read use (faster, no deps installed). The ability-level input is
	 *   `bootstrap=false`; this flag is the CLI shorthand (matches the
	 *   existing `--skip-context-injection` convention).
	 *
	 * [--allow-stale]
	 * : Bypass the staleness gate (applies to `add` only). By default,
	 *   `worktree add` refuses any branch/base that is behind the remote
	 *   default branch after fetch, and refuses to return a worktree that
	 *   would be more than
	 *   `datamachine_worktree_stale_threshold` commits (default 50) behind
	 *   upstream — the stale checkout is torn down and a `worktree_stale`
	 *   error is returned with remediation options. Pass `--allow-stale` to
	 *   opt in to a known-stale checkout. Default-branch freshness is
	 *   zero-tolerance: one missing default-branch commit is stale. The
	 *   ability-level input is
	 *   `allow_stale=true`.
	 *
	 * [--rebase-base]
	 * : After creating the worktree, rebase onto the upstream tip (applies
	 *   to `add` only). For existing branches this is `@{upstream}`; for
	 *   new branches cut off a local base this is `origin/<base>`. On
	 *   rebase conflicts the rebase is aborted and the worktree stays at
	 *   its pre-rebase state — `--rebase-base` is not a silent
	 *   `--allow-stale` bypass. The ability-level input is
	 *   `rebase_base=true`.
	 *
	 * [--task-url=<url>]
	 * : Optional task/issue URL recorded on the worktree at creation time
	 *   for ownership/duplicate detection (applies to `add` only). Falls
	 *   back to the `DATAMACHINE_TASK_URL` environment variable when
	 *   omitted. Used by `worktree list` and the hygiene report to flag
	 *   multiple worktrees pointing at the same task.
	 *
	 * [--task-ref=<ref>]
	 * : Optional short task/issue reference (e.g. `org/repo#123`) recorded
	 *   alongside `--task-url` (applies to `add` only). Falls back to the
	 *   `DATAMACHINE_TASK_REF` environment variable when omitted.
	 *
	 * [--force]
	 * : For `add`, explicitly bypass the disk-budget refusal threshold. For
	 *   `remove`, force-remove a worktree even if it is dirty. For `cleanup`,
	 *   force dirty-worktree removal but not the unpushed-commits safety.
	 *
	 * [--pr=<url-or-number>]
	 * : Attach pull request metadata when finalizing or marking a worktree
	 *   cleanup-eligible.
	 *
	 * [--state=<state>]
	 * : Lifecycle state to record when finalizing a worktree.
	 *
	 * [--dry-run]
	 * : Preview cleanup candidates without removing anything (cleanup and locks only).
	 *
	 * [--prune-stale]
	 * : For `locks`, prune expired DB lock rows and old unlocked filesystem lock
	 *   files. Active filesystem flocks are reported but never removed.
	 *
	 * [--apply-plan=<file>]
	 * : Low-level escape hatch for applying a previously reviewed JSON report.
	 *   Daily cleanup should use `workspace cleanup plan`, then
	 *   `workspace cleanup apply <run-id>`.
	 *   The destructive pass still revalidates every planned row and removes only
	 *   exact current matches. For reconcile-metadata, applies a reviewed
	 *   non-destructive metadata plan.
	 *
	 * [--apply]
	 * : For `reconcile-metadata`, apply DMC-owned bounded metadata reconciliation
	 *   directly without a JSON plan file. For cleanup subcommands, use the
	 *   operation-specific apply path instead.
	 *
	 * [--via-jobs]
	 * : For `reconcile-metadata --apply`, schedule bounded metadata
	 *   reconciliation pages as jobs instead of applying synchronously.
	 *
	 * [--skip-github]
	 * : Skip the GitHub API lookup and rely only on the local `upstream-gone`
	 *   signal (cleanup only). Faster, but misses merged branches where the
	 *   remote branch wasn't auto-deleted.
	 *
	 * [--inventory-only]
	 * : Build a dry-run review from cheap top-level inventory and explicit
	 *   lifecycle cleanup signals only (cleanup only). Avoids full git worktree
	 *   scans, per-worktree status checks, and GitHub lookups.
	 *
	 * [--include-repaired-metadata]
	 * : With cleanup inventory or bounded-cleanup-eligible-apply, explicitly
	 *   include repaired metadata rows as operator-approved cleanup candidates.
	 *   Apply still runs fresh dirty/unpushed/containment/primary safety probes.
	 *
	 * [--older-than=<duration>]
	 * : Limit cleanup candidates to worktrees with lifecycle `created_at`
	 *   metadata older than the compact duration (cleanup only, e.g. 7d, 24h).
	 *   Candidate worktrees without valid `created_at` metadata are skipped.
	 *
		 * [--sort=<field>]
		 * : Sort cleanup candidates by reporting field. For artifact cleanup,
		 *   `--sort=size` scans the cheap inventory once and returns the largest
		 *   artifact opportunities without manual pagination.
	 * ---
	 * options:
	 *   - size
	 *   - age
	 * ---
	 *
	 * [--stale]
	 * : For list, show only worktrees with a stale_reason (old, dirty, or missing metadata).
	 *   Implies `--with-status` (dirty detection requires running `git status`).
	 *
	 * [--with-status]
	 * : For list, run `git status --porcelain` per worktree to populate the dirty count.
	 *   Off by default — expensive on large workspaces (one fork+exec per worktree).
	 *
	 * [--with-size]
	 * : For list, run size and artifact `du` probes per worktree. Off by default —
	 *   expensive on large workspaces (multiple fork+exec calls per worktree).
	 *
	 * [--full]
	 * : For list, shorthand for `--with-status --with-size`. Restores the pre-0.27
	 *   behavior where every worktree is fully probed; only practical for small workspaces.
	 *
	 * [--verbose]
	 * : Show every cleanup row instead of concise samples (cleanup only).
	 *
	 * [--only=<section>]
	 * : Limit cleanup rows to one section or reason code. Supported values:
	 *   candidates, would-remove, would_remove, removed, no_merge_signal, dirty_worktree,
	 *   merged_pr_with_only_obsolete_dirty_changes (alias safe-force-cleanup),
	 *   unpushed_commits, missing_metadata, external_worktree, age_filter, unknown_age.
	 *
	 * [--limit=<count>]
	 * : For `cleanup --dry-run`, `cleanup-artifacts --dry-run`,
	 *   `abandoned`, `reconcile-metadata`, and `active-no-signal-report`,
	 *   positive maximum worktrees to scan in this page. Artifact cleanup defaults
	 *   to 100; metadata reconciliation uses this only when pagination is
	 *   requested. Use `--exhaustive` instead of `--limit=0` for a full artifact
	 *   audit.
	 *
	 * [--passes=<count>]
	 * : For `abandoned`, maximum apply passes to run after marking eligible rows.
	 *   Preview mode always runs a single non-destructive classification pass.
	 *
	 * [--stage=<stage>]
	 * : For `abandoned`, resume from a specific orchestration stage. Supported
	 *   values: reconcile, finalized, equivalent-clean, merged, remote-clean, bounded.
	 *
	 * [--offset=<count>]
	 * : For `cleanup --dry-run`, `cleanup-artifacts --dry-run`,
	 *   `abandoned`, `reconcile-metadata`, and `active-no-signal-report`,
	 *   pagination offset (0-indexed) into the inventory ordering. Walk pages by
	 *   passing the previous response's `pagination.next_offset`.
	 *
	 * [--until-budget=<duration>]
	 * : For `cleanup --dry-run` and `reconcile-metadata`, enforce a compact
	 *   wall-clock budget for dry-run pages or direct-apply drains (e.g. 60s,
	 *   10m). Also supported by `active-no-signal-report` and the active/no-signal
	 *   apply flows. Returns continuation
	 *   evidence and a next command when more rows remain.
	 *
	 * [--exhaustive]
	 * : For `cleanup-artifacts --dry-run`, scan every worktree AND run per-worktree
	 *   git safety probes. This is the explicit unbounded artifact audit mode;
	 *   slow on huge workspaces, so use sparingly.
	 *
	 * [--safety-probes]
	 * : For `cleanup-artifacts --dry-run`, run per-worktree git safety probes
	 *   without disabling the bounded scan. Useful for auditing a small slice
	 *   with full safety information.
	 *
	 * [--pr=<url-or-number>]
	 * : Pull request URL or number for `finalize` or `mark-cleanup-eligible`
	 *   metadata. Supplying `--pr` to `finalize` defaults the requested finalizer
	 *   state to `pr_opened` and records the worktree as cleanup-eligible.
	 *
	 * [--state=<state>]
	 * : Requested lifecycle state for `finalize`. Defaults to `pr_opened` when
	 *   `--pr` is supplied, otherwise `active`. PR/completed states are safely
	 *   transitioned to cleanup eligibility metadata.
	 *
	 * [--format=<format>]
	 * : Output format for list and cleanup (table, json, csv, yaml).
	 *

	 *     wp datamachine-code workspace worktree add data-machine fix/foo
