/**
 * Tests for `src/planning-inspect.cts` — the schema-v1 canonical planning
 * snapshot (`query planning inspect` / `query planning.inspect`, #2790).
 *
 * Design:       .gsd/phase/feat-2790-planning-inspect/40-design.md
 * Test matrix:  .gsd/phase/feat-2790-planning-inspect/50-test-matrix.md
 *
 * Fixture provenance (CONTRIBUTING.md "Fixture provenance (#2371)"): every
 * `.planning/` document shape written by this file's fixture builders is
 * derived from the SHIPPED templates the product author wrote —
 * `gsd-core/templates/requirements.md` (checkbox bullets, `## Traceability`
 * table), `gsd-core/templates/phase-prompt.md` (the `<task>` XML grammar and
 * `## Task N` legacy heading fallback), `gsd-core/templates/summary.md`
 * (`## Files Created/Modified`, `## Deviations from Plan` / `**Found
 * during:**` / `**Files modified:**`), `gsd-core/templates/state.md`
 * (`## Current Position`), and `gsd-core/templates/roadmap.md` (`## Phases`
 * checkbox list, `### Phase N: Name` headings) — never from
 * `planning-inspect.cts`'s own parsing model. `planning.inspect` has no
 * writer of its own (it is read-only), so the property-test generator in
 * this file (`propertySchemaIsTotalOverDocumentShapedInputs`) is
 * document-shaped from those same templates, not seeded from the module
 * under test.
 *
 * `runGsdTools(['query', 'planning', 'inspect'], tmpDir)` is the invocation
 * shape used throughout — array form, shell-bypassed, safe for hostile
 * fixture values (CONTRIBUTING "CLI and command routing").
