The import wizard forgets its format between runs: import_sources carries
neither amount_mode nor sign_convention, so a source configured for positive
expenses silently flips every amount on its second import.
Force-added despite .gitignore so /autopilot workers can read them from a
worktree — same precedent as PR #295 (ADR 0016 shipped a dead Spec: line).
Plan reviewed by the 3-expert pass: 7 criticals integrated, 8 decisions
drained. Milestone planned-2026-08-12-import-csv-format (#323-#332).
