GNIZDO 0.2.0 makes both boundaries explicit instead of guessing.
Automatic identity, only when the evidence is strong enough
GNIZDO can now confirm shared product identity automatically from an exact valid GTIN, or from an exact SKU that is unique per channel with no conflicting valid GTIN. Ambiguous, duplicate, or conflicting evidence stays unconfirmed for review.
Product Truth keeps the confirmation method and evidence visible. A familiar title is still not proof, and confirmed identity is still not synchronization.
Different stock can be deliberate
On a confirmed Product Truth mapping, a seller can now declare the intended stock relationship: Unknown, Should match, Intentionally different, or Independent.
GNIZDO keeps the raw channel observations visible and uses that declaration only as context for evaluation. A trusted difference can remain a stock mismatch when the intent is unknown or the listings should match; an intentional or independent difference does not need the same finding.
The boundary stays narrow
This release does not add automatic cross-channel stock synchronization, warehouse truth, inventory pools, caps, reserves, percentage allocation, or overselling arithmetic. GNIZDO still starts with evidence and only makes the conclusion the evidence can support.
