/*
<MODULE_CONTRACT>
  <purpose>Lazy-loading kernel module for RFC-0357 behavior snapshot commands: capture and diff, comparing structural output between builds.</purpose>
  <non-goals>
    <item>Do not re-export types or utilities — the barrel behavior-snapshot/index.ts remains the public API surface.</item>
    <item>Do not register release or artifact-store commands here.</item>
  </non-goals>
</MODULE_CONTRACT>
<CHANGE_SUMMARY>
  <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>
  <item>RFC-1231: step 1 — rename supportsAllSites to acceptsAllFlag

Mechanical sweep: the field only ever gated --all argv acceptance; fan-out
follows the parsed selector. Guard renamed assertAllSitesAllowed ->
assertAllFlagAccepted, message updated. 417 declaration sites + type
surfaces (KernelCommandMetadata, ForgeCommandMetadata) in one atomic pass.</item>
