msd-core/tests/skill-frontmatter-contract.test.cjs

// allow-test-rule: source-text-is-the-product
// The commands/msd/*.md and msd-core/workflows/*.md files are the
// installed agent stubs — their frontmatter and workflow body IS the
// deployed contract. These assertions check structural fields (argument-hint,
// description, early-exit prose) that govern runtime routing.

/**
 * Skill frontmatter contract tests
 *
 * Moved here from bug-3042-3044-research-flag-and-stale-refs.test.cjs
 * during the docs-parity polarity refactor (#3049). The original file
 * mixed two concerns:
 *   (a) docs-parity deny-list checks    → replaced by docs-parity-live-registry.test.cjs
 *   (b) frontmatter-structural checks   → this file
 *
 * These tests assert structural invariants in command-stub frontmatter and
 * workflow prose — they are NOT docs-parity checks. They verify that flags
 * are wired, descriptions are correct, and early-exit prose is present in
 * the right sections. These tests need to remain even after the deny-list
 * tests are removed.

/**
 * Feature #3039: tiered /msd:help output.
 *
 * The legacy single-file 747-line help is replaced by:
 *   - workflows/help.md             — small dispatcher (progressive disclosure)
 *   - workflows/help/modes/brief.md   — ~one-liner refresher
 *   - workflows/help/modes/default.md — one-page newcomer tour
 *   - workflows/help/modes/full.md    — complete reference (former help.md body)
 *   - workflows/help/modes/topic.md   — section-extraction logic + alias table
 *
 * This test enforces the contract:
 *   1. All four mode files exist with a single `<reference>` block.
 *   2. brief and default fit a "one screen" budget; full stays under LARGE tier cap.
 *   3. The dispatcher routes on $ARGUMENTS to all four mode files (structural parse).
 *   4. Dispatcher conflict-resolution rules are documented:
 *      - `--brief` + `--full` without a topic → prefer `--full`
 *      - `--brief <topic>` → topic.md in compact scope (composable)
 *      - bare or `--full <topic>` → topic.md in full scope
 *   5. topic.md documents an explicit routing preamble + compact-scope rule.
 *   6. Every topic alias in topic.md resolves to a heading that exists in full.md.
 *   7. Every /msd:* sub-block token in topic.md's alias table appears in full.md.
 *   8. Every full.md heading is either aliased or in the intentional-orphan allowlist.
 *   9. The `commands/msd/help.md` shim passes `$ARGUMENTS` through and advertises
 *      the composable `--brief <topic>` form.
 *
 * Tighten-only invariant (issue #597): ceilings track the per-tier high-water mark
 * within GRACE lines. Budgets may only decrease, never silently creep upward.
 * The assertTightCeiling() calls below enforce this automatically.
