// F3.2-F1 (Cycle 10 Wave 2, D3 High): top-level coverage for src/cli/commands/validate.ts.
// The pre-existing src/__tests__/cli/commands/validate.user.test.ts only
// exercises a narrow user-content slice (D20 gates against `.hatch3r/overrides/`).
// This file targets the structural validation surface that runs against the
// bundled canonical content (frontmatter contract, orchestrator marker,
// efficiency frontmatter, anti-slop scan, pillar-reference check, JSON-mode
// output, --strict-content escalation, --docs counts, and the public
// validateCommand E2E flow with a mocked canonical-root).
//
// Unit-tests over exported helpers (validateCommandOrchestratorFrontmatter,
// validateEfficiencyFrontmatter, scanAntiSlopHits, hasPillarReference,
// validateDocsCounts) and E2E tests over validateCommand share the same
// vitest file so module-load side effects (HATCH3R_PREFIX import, manifest
// reader) only initialise once.

// code read that table, so it drifted from 7+ agents' inline lines (context-
// rules most wrong). The root-cause fix deletes the duplicate column: each
// `agents/hatch3r-*.md` inline trigger line is the single source of truth.
// This guard locks the deletion in — if a future edit reintroduces a parallel
// per-agent table, the drift surface returns and this test fails.
//
// Reads the CANONICAL source under the package root (agents/shared/...),
// deliberately NOT resolveBundledContentRoot(): that resolver prefers a stale
// dist/content/ copy when one exists, and dist/ is gitignored + rebuilt, so
// asserting against it would test the wrong (possibly pre-edit) bytes.
