gqa(adr): ADR-0064 Rev2 (structural dispatch cost) + ADR-0065/DDD-0065 (flat-ops composite + softmax_merge recipe)
ADR-0064 Revision 2: replace per-op-type calibration table with a
structural formula `FIXED_PER_CMD + cmd.logical_bytes × R`, defaults
anchored at typical composite ≈ 45 ns. Topology yaml override under
`pe_cost_model:` block; logical_bytes property per PE command.
ADR-0065: implement ADR-0060 §5.6 / §8 item 4 carve-out as a flat-ops
CompositeCmd (no head/epilogue structural fields — position + scope
drives placement) + first stateful recipe `softmax_merge` (MATH-only
8-step). RECIPE_DESCRIPTORS lives in TLContext-adjacent module only;
PE_SCHEDULER stays recipe-free and auto-inserts DMAs from operand
`space`. Strict-FIFO RW hazard tracker; ≤1 GEMM per composite
invariant. User-facing `tl.composite(prologue=[...], op=, epilogue=[...])`
API preserved; existing benches unchanged (meaning-preserving refactor).
DDD-0065: implementation-ready phased plan (P0=ADR-0064 Rev2 first,
P1-P6 for ADR-0065), file plan, recipe engine sequence, scheduler
plan-gen algorithm, RW tracker design, test matrix.
