/*
<MODULE_CONTRACT>
<purpose>RFC-0479: the migrator registry — forward-only codemods keyed by RFC-id,
ordered by RFC-id (numeric). Replaces the old RFC-0221 SemVer-based registry.</purpose>
<non-goals>
  <item>Do not apply migrators here — selection only.</item>
  <item>Do not delete migrators — the registry is append-only.</item>
</non-goals>
</MODULE_CONTRACT>
<CHANGE_SUMMARY>
  <item>RFC-0757: register rfc-0757 no-op migrator (send-message checklistItems generalization, advances cursor).</item>
  <item>RFC-0885: register rfc-0885 content migrator (consentStatus→consentScope, add default display to Nachweis evidence-source).</item>
  <item>RFC-1105: register rfc-1105 share-path-rewrite migrator (werkstatt-shared share/X → werkstatt-shared/X specifier rewrite in workpieces).</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>
