$\textbf{🟡\ Medium\ Severity\ —\ Error\ Handling}$

NextSustLedgerPreviewEntryNo uses 0 as its "not initialized" sentinel, but a counter that starts at -2000000000 can legitimately reach 0. On the next preview insert, this code resets the counter back to -2000000000 and reuses an existing temporary primary key, so a sufficiently large preview fails with a generic duplicate-key/runtime error instead of a controlled exhaustion check. Use a non-reachable sentinel or add an explicit guard when the negative preview range is exhausted.

The counter only reaches 0 after about 2 billion previews in one session, so it is not reachable in practice.

$\textbf{🟠\ High\ Severity\ —\ Telemetry}$

FeatureTelemetry.LogUsage('0000PH5', ...) and LogUptake(..., "Used") are still called unconditionally near the top of InsertLedgerEntry, before the new OnInsertLedgerEntryOnBeforeInsert/IsHandled branch decides whether a real ledger entry is ever persisted. With the new preview-diversion path, a call that ends up fully handled (no physical Insert) still reports feature usage as if a real Sustainability Ledger Entry was created, inflating usage telemetry for preview-only invocations of this procedure and making usage counts unreliable for measuring real adoption.
