## 1. SCOPE REVIEW VERDICT CHANGE APPROVAL REQUIRED The proposed instant refunds and automatic payment reversals are additional financial capabilities not explicitly included in the agreed baseline. Both require formal change approval before implementation. | Item | Finding | | ---------------------------- | ------------------------------------------------------------------------------------------------- | | Instant refunds | NEW SCOPE — provisional | | Automatic payment reversals | NEW SCOPE — provisional | | Delivery risk | HIGH — potential ledger inconsistency, duplicate financial movements, and reconciliation failures | | Current constraint | Live banking platform; zero downtime permitted | | Critical blocker | Ledger dependencies undocumented | | Implementation authorization | NOT PROVIDED | The established baseline covers real-time transfers, verified balances, and daily reconciliation. It does not explicitly establish refund execution or automated payment reversal behavior.  Teks yang ditempel (1).txt Recommendation: Submit both capabilities for change approval, but hold implementation until ledger dependencies, transaction rules, and reconciliation safeguards are validated. The classification could change if an authoritative earlier agreement explicitly includes these capabilities. ## 2. BASELINE VS. CHANGE REGISTER | ID | Agreed Baseline | Requested Change | Classification | Evidence / Gap | | ----- | -------------------- | --------------------------------------- | -------------------------------- | ------------------------------------------------------------------------------- | | SC-01 | Real-time transfers | Instant refunds | NEW SCOPE | Refund capability not explicitly committed | | SC-02 | Real-time transfers | Automatic payment reversals | NEW SCOPE | Reversal triggers and rules unspecified | | SC-03 | Verified balances | Reflect refunds and reversals correctly | SCOPE MODIFICATION — conditional | Existing balance requirement remains; new transaction behavior needs definition | | SC-04 | Daily reconciliation | Reconcile refund and reversal entries | SCOPE MODIFICATION — conditional | Ledger posting and reconciliation rules undocumented | No existing obligations are proposed for removal. The real-time transfer, verified balance, and daily reconciliation commitments must remain intact. Zero downtime remains a mandatory delivery constraint. ## 3. DELIVERY IMPACT ASSESSMENT | Area | Expected Impact | Evidence Status | Required Response | | --------------------- | ------------------------------------------------------------------------------------ | --------------- | ----------------------------------------------------- | | Ledger integrity | Potential duplicate postings, incorrect balances, or unmatched entries | INFERRED | Trace posting and settlement flows | | Transaction lifecycle | Refund and reversal eligibility, states, and finality are undefined | UNKNOWN | Define transaction state transitions | | Integrations | Payment processors or external settlement systems may impose restrictions | UNKNOWN | Verify integration contracts and capabilities | | Reliability | Partial execution, retries, and concurrent requests may create inconsistent outcomes | INFERRED | Design idempotency and recovery controls | | Reconciliation | New transaction types may require matching and exception-handling changes | INFERRED | Validate journal entries and reconciliation rules | | Deployment | Schema or service changes could threaten availability | INFERRED | Establish a no-downtime rollout and rollback strategy | | Budget / schedule | Additional engineering and validation work likely | INFERRED | Estimate after dependency discovery | ### Critical dependency chain Refund / reversal request Transaction eligibility and state validation Ledger posting and balance updates Settlement and reconciliation Verified financial outcome Must preserve existing balance and reconciliation commitments Refunds and reversals may require different transaction handling. They should not be treated as interchangeable operations. A lower-risk alternative is to evaluate whether existing payment-provider functionality supports the required outcomes before introducing new ledger behavior. Availability of that functionality is currently UNKNOWN. ## 4. APPROVAL-READY CHANGE RECORD | Field | Decision Record | | ----------------------------- | ----------------------------------------------------------------------- | | Change requested | Introduce instant refunds and automatic payment reversals | | Business need | NOT PROVIDED | | Scope additions | Refund processing, reversal automation, associated transaction controls | | Scope removals | None identified | | Preserved commitments | Real-time transfers, verified balances, daily reconciliation | | Operational constraint | Zero downtime | | Financial quality requirement | Finance demands zero reconciliation errors | | Technical dependencies | Ledger model, transaction lifecycle, settlement integrations | | Schedule adjustment | UNKNOWN — requires estimation | | Budget adjustment | UNKNOWN — requires estimation | | Approval authority | UNKNOWN | | Implementation owner | UNKNOWN | | Recommended disposition | Request approval; hold implementation pending prerequisite evidence | ### Mandatory acceptance conditions 1. Refund eligibility, authorization, timing, and failure behavior are documented and approved. 2. Automatic reversal triggers, finality rules, and recovery behavior are defined. 3. Duplicate requests and retries cannot cause duplicate financial movements. 4. Ledger entries and resulting balances remain internally consistent across successful, failed, and partial operations. 5. Reconciliation validation demonstrates zero unexplained discrepancies across an agreed test suite; the scope and interpretation of the zero-error requirement must be confirmed with Finance. 6. Deployment and rollback preserve platform availability without interrupting existing transfer operations. 7. Authorized stakeholders approve the revised scope, acceptance criteria, dependencies, and supported delivery estimates. These are proposed approval conditions, not previously agreed requirements. ## 5. PRIORITIZED NEXT ACTIONS | Priority | Action | Completion Evidence | | ------------ | ------------------------------------------------------------------------------------------------ | -------------------------------------------------------------- | | 1 — BLOCKER | Map the ledger, transaction lifecycle, settlement dependencies, and existing refund capabilities | Reviewed dependency map and identified restrictions | | 2 — REQUIRED | Define refund/reversal rules, acceptance criteria, and delivery impact | Change specification, validation plan, and supported estimates | | 3 — APPROVAL | Submit the change to authorized decision-makers | Recorded approval or rejection, with scope and conditions | ### Final decision Proceed now with dependency discovery, feasibility analysis, and change specification. Do not begin production implementation, alter ledger behavior, or commit to delivery dates until essential technical evidence and formal authorization are available. The request may be valuable, but its commercial justification, operational feasibility, and safe deployment path are not yet demonstrated.
