The managed callback cases previously covered Wire inputs. This adds independently written Antelope SHiP bytes using the pinned Leap v5.0.3 ABI and the builtin native provider. The emitted reader/MainDS/DS paths retain original ingress and distinguish a confirmed contract handoff, an encoded-empty trace vector and unavailable traces.

Native parent/worker IPC, real retained stores with two-copy receipts and the actual master adjudicator verify original semantic membership plus the same attempt's fresh result and authenticated end before private association. Stale configuration, physical target UUID, canonical identity and configuration replacement during an awaited target read remain unresolved. Source, ABI deployment, ordinals, producer, executable and runtime pins are retained.

This is the first slice of #321; the issue remains open for actual reversible-source/coordinator revocation and pending-worker qualification. Parent #289 stays draft. Constructed source and controlled service/RPC transports do not establish live-chain, capacity, full replay or release acceptance. No production behavior, dependencies or budgets change.

Validation at 1626fafb:

• All three focused cases pass on native Node 24.19.0 and 26.4.0, with exact source/runtime result records.
• Complete-project Bun 1.4.4 / TypeScript 7.0.2 check passes for all 258 application files, and native TypeScript emission passes.
• Full root suite: 1,476 passed, 18 optional skips, zero failures, 10,046 assertions across 1,494 tests / 131 files.
• Independent complete-delta Spec and Standards reviews: zero actionable findings; both verified the primary upstream ABI extraction.
• All nine CI jobs pass. Both native Node 24/26 build jobs report 1,493 passed, one optional skip, zero failures and 10,080 assertions across 1,494 tests / 131 files; all three new Antelope cases actually execute.
• Copilot could not run its review because quota was unavailable; independent Spec and Standards reviews completed.
