Keep positive topology differences separate from unpaired neighbor identity. Preserve exact content pairing and source observations, report unresolved relationships without inventing incomplete inventory, and omit comparison edges when no substantive difference was observed.
Validated with 45 focused domain/CLI/MCP tests, nine expanded domain controls, check:fast, and docs:check. Clean baseline fails seven controls and passes two positive controls. Controlled static fixtures only; no target execution or large-bundle profiling.

Keep location-only matched pairs unchanged under complete coverage while retaining both coordinates and location dimensions. Preserve incomplete coverage as unknown and retain definite content, property, and relationship changes.
Validated with focused domain, compiled CLI and MCP workflows, static checks and docs checks. A tiny public CLI bundle fixture reproduces the issue; the reported Bitwarden releases were not rerun.
