<MODULE_CONTRACT>
<purpose>Facilitates the registration of semantic layer validation commands per RFC-0042.</purpose>
<non-goals>
  <item>Do not implement content generation — validation only.</item>
  <item>Do not manage semantic builder logic — only check outputs.</item>
</non-goals>
</MODULE_CONTRACT>
<KEY_DECISIONS>
  <item>Module registers commands only — semantic layer logic lives in sibling modules.</item>
</KEY_DECISIONS>
<CHANGE_SUMMARY>
  <item>RFC-0042: Created semantic module with page validation command.</item>
  <item>RFC-1097: step 6 — compass.migrate codemod run

Mechanical v1 to v2 header migration across the workspace: 942 files rewritten — CHANGE_SUMMARY windows collapsed into history, forbidden v1 blocks stripped, KEY_DECISIONS seeded from @ai-invariant comments (5 files) or TODO placeholders (103 files), blocks reordered to canonical order.</item>
  <item>RFC-1097: sweep — werkstatt-engine clean

Sweep batch 4: 73 Compass headers on headerless engine files (certification, component-runtime, isolation, evolution, testing), real KEY_DECISIONS on 75 files (kernel, cache, dht, swim, gitmesh, runtime), ~80 purpose expansions (CONTRACT-02/PURPOSE-02), non-goals on 13 CONTRACT-03 files, CS-07 history literal fix repo-wide (253 files). Policy: .template.ts/.template.astro excludedPaths. werkstatt-engine now 0 diagnostics.</item>
  <item>RFC-1173: declare mutatesState on all kernel commands — collectDeclarationDiagnostics emits error-severity MUTATES-STATE-DECLARED, command.manifest.validate is the blocking consumer in packages.check, sweep declares the flag on every command definition (factories hardcode false for read-only check specs)</item>
