Fixes the reds on main with no owner: 18 of the 20 found by the #2762 fork, plus holder_standing_rules, unowned_checkout_work and test_commander_forks ×4. The rest belong to #2763 or are environment-only.

Cause (src frame)	Breaking commit	Fix	Tests
todos.py:3911 bare snapshot.by_lookup[...] KeyError for an unregistered unit	1f48379 (#2735)	read threads_for; an unregistered unit has no recorded worktree to share	test_todos: create_is_idempotent, new_mutation_inherits_revision_admission, withdraw_retires_a_released_problem, withdraw_refuses_a_delivered_problem[True/False], two_processes_assign_one_todo, validation_rejects_ambiguous_identity, merged_order_keeps_its_checked_fields
todos.py:2184 reads Commander.worktrees, deleted by d729bab; every order send crashed	d729bab	storage_rule.checkout_base, the same owner d729bab used for the other caller	test_holder_standing_rules::test_send_and_check_accept_a_deletion_check_on_fresh_main
storage_rules.py:89 froze Path.home() at import, so checkout_base pointed at the real ~/wt under a test HOME	old, exposed by d729bab	default_factory, read when the rule is built	same holder test (it asserted no worktrees under the real ~/wt)
goals.py:138 passes Thread.created_at (now CreationTime) into float fields	d5cd4bb	incarnation.wire_birth, as goal_mentions.py does	test_goal_mentions ×5, test_relationships::test_retained_alias_contact_without_projected_person_is_unavailable
installer/backup.py:333 copy_tree KeyError on a lock file written after the owners were read	57b51b6	regular files with no owner are not copied	test_connector::test_connector_channel_history_on_a_copy_leaves_unread_unchanged

pr_commander configured a second checkout (the real repo) of the same GitHub repo; the standing rule compared it against the fixture's installed commit (git 128), and fetched the real checkout	458281e/b9bbbfc8e	configure only the plan-bearing source	test_todos::test_watcher_git_and_github_reads_leave_wire_free, test_installed_merge_closes_only_the_run_that_has_been_proven
Fixtures registered two order holders in one worktree, which #2735 now refuses	1f48379 (#2735)	idle / outsider / each fork unit gets its own git worktree	test_unowned_checkout_work, test_holder_standing_rules, test_commander_forks ×4

Debt ratchet kept flat: the first head grew BooleanChainTerms in backup.py (+4), TodoStore GodClassExcess (+4) and LongBooleanChain (+1). copy_tree's filter is now one passes predicate, and require_assignment_in builds one worktree set instead of an inner chain.

Left to #2763: historical_views.py:201 ThreadTarget.removeprefix (test_command_families[DmHistoryPageResult], test_connector newest-first pages, test_unowned_checkout_work dirty→pushed). These pass on the current main merge. Also test_store_backup ×2, test_install_rehearsal ×7 and test_carry_bus_history::test_predecessor_publisher_history_round_trips_into_bus (HistorySource bus-identity schema; the file is in #2763).

test_runtime ×3 (new_session_metadata display title, subscription_replay_uses_requested_alias[True/False]): environment, not code. They pass on this head. On a fresh main worktree they fail only with NativePackageError, because stack/.pi-native-* was never prepared; CI prepares it in .github/actions/prepare-native.

Environment, not code: test_watcher and test_installed_merge also refuse Insufficient free space before building the practice copy when basetemp is the 7.8 GB tmpfs /tmp (4.6 GB free, under the 5 GiB floor). With --basetemp on disk they pass.

Still unowned, red on main before this PR: test_storage_violations ×5 (SQLITE_CANTOPEN on wire/bus.sqlite3).

Local runs: the touched files pass apart from the #2763-owned and storage_violations reds above, and no test is newly red against main (merged through #2777). Ruff findings on the touched files are identical to base.
