TEST-082

Stimulus

Exercise tag lookup exits 0, 2, 128 and unexpected errors; denied authorization and validation errors; an unrelated draft hidden by get-by-tag; incomplete or changing inventories; wrong or same-SHA concurrent tags; annotated tags; lost responses; late commits; and restored local journals.

Required observation

A proven absent tag is distinguished from existing or failed lookup. Confirmed conflicts fail; unauthorized or ambiguous state is UNKNOWN. An identical tag alone is not attribution, no ambiguous request is blindly retried, and no dependent side effect or success occurs until the exact intent, result, and late-effect risk are reconciled.
