tl.program_id(axis=1) returns cube id. Enables cube-aware
sharding in benchmark kernels.

- CLI: --verify-data flag enables Phase 2 data verification (ADR-0020)
- Tensor.data: returns actual numpy values (verify-data) or zeros placeholder
- Tensor.__repr__: shows value summary or data=N/A (placeholder)
- DataExecutor: ThreadPoolExecutor for same-timestamp parallel op execution

Design for actual data storage/computation in HBM/TCM/SRAM components:
- Phase 1: SimPy timing + MemoryStore (memory ops data-aware via greenlet)
- Phase 2: op_log-based numpy execution for GEMM/Math verification
- Greenlet-based KernelRunner replaces Phase 0 command list generation
- tl.load() returns real data in Phase 1, enabling memory-based control flow
- ComponentBase hook for op logging (single source of truth)
- MemoryStore: numpy ndarray tensor-granular storage with reference semantics

Component placement uses mm coordinates in topology.yaml, mesh_gen
finds the nearest router automatically. M_CPU moved to pos_mm=[7.5,2.0]
(→ r0c2), SRAM at pos_mm=[1.5,9.0] (→ r3c0).
No hardcoded router references in topology config.

Stub length increased to 12px (PE/HBM) and 10px (UCIe).
Gap between router and component increased to 30px so both
45° stubs (router end + component end) are clearly visible.

- M_CPU placed north (above) its router
- All connectors: 45° stub from router → straight → 45° stub to component
- Consistent 4-point polyline pattern for PE, M_CPU, SRAM, HBM, UCIe

UCIe position calculated with minimal inset (0.3 × size) to
place components flush against cube boundary edges.

All connectors now start with 45° diagonal from router edge,
then go straight (vertical/horizontal) to the component block.
Applies to PE, M_CPU/SRAM, PE→HBM, and UCIe connectors.

Router-router mesh links remain straight (horizontal/vertical).
All component→router connectors use 45° L-bend polylines:
- PE blocks: vertical then 45° diagonal to router
- M_CPU/SRAM: horizontal then 45° diagonal to router
- PE→HBM port group: vertical then 45° diagonal
- UCIe port→router: direction-aware 45° bend

UCIe components placed at defined positions from _cube_local_positions
with size from cube.geometry.ucie_mm.size. N/S horizontal, E/W vertical.
Connection ports rendered as color-coded boxes inside UCIe component.

- UCIe-N/S/E/W drawn as component blocks inside cube boundary
(inset 3mm from edge)
- Each UCIe has c0-c3 connection ports as color-coded boxes inside
- Connector lines from each port box to its attached router
- Removed old UCIe rendering that placed blocks outside cube

- HBM pseudo channel ports split to top/bottom edges of HBM zone
(32 ports each, 8 per PE, color-coded)
- PE→HBM lines connect router to its port group center
- Per-PE label: "PE0×8ch" with BW annotation
- UCIe blocks flush against cube edges at router positions
- UCIe blocks smaller (22×10px)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- HBM connection lines angled 30% toward HBM center (not vertical)
to distinguish from mesh links
- M_CPU/SRAM blocks placed to the left of their router
with horizontal connector lines (avoid mesh overlap)

Draw HBM connection lines last (on top of component blocks).
PE routers: thicker (1.5px, opacity 0.6) with dashed style.
Relay routers: thinner (0.7px, opacity 0.2).

All router-attached components (PE, M_CPU, SRAM, UCIe) rendered as
labeled blocks with explicit connector lines to their router.
UCIe blocks positioned at cube edges matching port direction.
Router→HBM_CTRL lines shown for all 32 routers.

Shrink cube-view component nodes to avoid clutter.
HBM and router_mesh edge lines made thinner and more transparent.

PE nodes are shifted 1.2mm above (top half) or below (bottom half)
their assigned router position. PE size reduced to 1.4x0.7mm.

- cube_view now renders all 32 router nodes from cube_mesh.yaml
instead of collapsed "router_mesh" placeholder
- Fix mesh_gen row Y position overlap (r1/r2 and r3/r4 had same Y)
by adding hbm_gap spacing between PE rows and HBM zone
- Add noc_router to visualizer KIND_SIZE for proper sizing
- Update cube view tests for individual router nodes

Add router → PE_MMU edge so MmuMapMsg can reach PE_MMU via

RuntimeContext._ensure_allocators() now limits SIP range to
target_device (single SIP or all). Prevents cross-SIP tensor
deployment that caused PE_TCM routing errors.
Also accept 'sip0' format (without colon) in DeviceSelector.

- Add NOC→PE_DMA and PE_CPU→NOC edges in topology builder
- Make HBM BW test assertions dynamic based on topology efficiency
