Warm-cache bs>1 requests can carry duplicate logical page ids across request rows. A batch-global page inverse collapses those request slots and can alias current/prefix KV across requests. The runtime now carries compact row-scoped sorted page descriptors and remaps flattened logical locs with request row ids where needed, while retaining the legacy global inverse for no-row-context paths. Constraint: Avoid the rejected dense [batch, logical_page_capacity] inverse because bs up to 10 and long contexts make that memory cost unacceptable Rejected: Keep global page_inverse for bs>1 duplicate pages | it is lossy and matches the GSM8K warm-cache corruption shape Rejected: Allocate page_inverse_by_row | correctness-safe but too much GPU memory for production Confidence: medium Scope-risk: moderate Directive: Any future TAI materialize fast path for bs>1 duplicate pages must consume row-scoped descriptors or an equivalent request-row key Tested: Local py_compile for touched runtime files; remote py_compile; remote pytest test_cp_shared_kv_runtime.py, test_nsa_cp_utils.py, test_cp_shared_kv_layout.py => 263 passed, 5 warnings, 2 subtests passed Not-tested: Full GSM8K ETE after this cleanup pass
