Summary

• Emit each desyndication attestation from live outstanding shadow after its transfer and burn, including notification-driven nested requests.
• Authenticate the self-inline continuation and preserve fees, bucket debits, recorded returns and request identities.
• Cover holder reentry, rollback, forged emissions and trailing action bytes; synchronize the contract and callback-helper ABI/WASM artifacts.

Why

Desyndication previously encoded outstanding supply before its queued transfer and burn executed. A holder notification could re-enter, making the later outer attestation overstate outstanding shadow and falsely freeze a fully backed outpost. The final self-inline action reads the recorded request and live supply plus parked yield, then queues the attestation without an intervening external callback.

The one-shot unprivileged callback completes within the default inline depth of four. The combined contract preserves upstream return-envelope epoch tracking, automatic balance-row creation and strict action-data decoding.

Validation

• Focused Synd, LIQ, message-channel, dispatch, token and swap suites under --sys-vm-jit: 243 cases and 21,068 assertions passed, including live nested/outer totals, fees and parked yield, rollback and emission authorization.
• Scheduler, action-data and notification checks under JIT: 13 cases and 158 assertions passed.
• ON/ON contract build succeeded with the selected CDT; all 56 tracked contract artifacts matched their native outputs.
• Reproducer control from the original fix: the unfixed artifact reports stale outer outstanding of 67 instead of 47; the fixed callback regression passes.
• Independent correctness, architecture, compliance and style reviews passed.

• wire-ethereum #296: zero-tolerance ordered-payout regression with explicit already-paid replay assertions; targets next. Part of the same coordinated merge batch.
• wire-solana #618 (merged): exact-custody ordered-payout regression; targets next.
• wire-tools-ts #181 (merged): shared Solana AuthEx bootstrap fix using the already published SDK 1.0.110; targets master. Include the selected fix branch in coordinated validation.
