v2026.6.6

Added

• CI Gate 13 — LLM Chokepoint Guard: forbids LLM resolution + client/transport construction outside the single ModelRunner chokepoint that PR #954 established (six baselined rule classes; baseline mode like Gate 3). (provenance: T11783; #956)

Changed

• Migrate the remaining LLM consumers (role-executor, auxiliary-fallback, llm-stream) onto the single ModelRunner, collapsing four inline transport branches into one deriveApiWire + buildTransportFromCredential call. (provenance: T11745; #957)

Fixed

• Centralize the Anthropic OAuth anthropic-beta header in ModelRunner, fixing a latent gap where the session-factory/auxiliary-fallback OAuth path omitted the required header (silent 401s). (provenance: T11745; #957)
• Exodus verifyMigration now applies source-side coercion (epoch/enum/clamp) so equal data digests equal — eliminating the false hashMatch mismatch that aborted an otherwise-lossless cutover. A real-data nexus/signaldock audit found zero enum drift. (provenance: T11809; #958)
• Release reconcile provenance backfill inserts FK-ordered and skips-with-warn for the post-cutover bare-tasks split-brain, so the 11 provenance tables backfill and changesets archive (DHQ-051). (provenance: T11659; #959)
