PINK: E2E trace analysis — Pass 12 sync/async wider scope (O1-O11)

Browse Source 
Twelfth pass: _maybe_close asyncio.run silently skips close from async
context (O1), _pick_live_symbol missing await crashes on coroutine iteration
(O3), _run() pool .result() no timeout — backend hang freezes process (O5),
KernelSlotView.__getattr__ N FFI calls for N fields no caching (O8),
DITAv2LauncherBundle no __del__ leaks resource tree (O9), ExecutionKernel
no close() — __del__ only cleanup (O10), __setattr__ triggers 5 persistence
side effects undocumented (O11). 254 total flaws.

## O-Series: Sync/Async Wider Scope (Launcher, Generators, Streams, FFI, Tests) (Pass 12)
*Full detail in TRACE doc under "PASS 12 — SYNC/ASYNC WIDER SCOPE."*
| # | Flaw | Layer | Severity |
|---|------|-------|----------|
| O1 | `_maybe_close()` asyncio.run without loop guard — close skipped from async context | Launcher | **High** |
| O2 | `async def connect()` shims call sync venue.connect() without await — blocking | Test | Medium |
| O3 | `_contract_rows(client)` NOT awaited — `_pick_live_symbol` iterates coroutine = crash | Test | **High** |
| O4 | Deprecated `get_event_loop().run_until_complete()` in test file | Test | Medium |
| O5 | `_run()` thread pool .result() no timeout — backend hang freezes process | Venue | **High** |
| O6 | MockVenueAdapter never exercises thread-pool bridge — untested in CI | Venue | Medium |
| O7 | `_keepalive_loop`/`_rotation_sentinel` fire-and-forget — exceptions silently lost | Stream | Low |
| O8 | `KernelSlotView.__getattr__` N FFI calls for N fields — no caching | Bridge | Medium |
| O9 | `DITAv2LauncherBundle` no `__del__` — GC'd bundle leaks resource tree | Launcher | Medium |
| O10 | `ExecutionKernel` no `close()` — Rust handle only freed by unpredictable __del__ | Bridge | Medium |
| O11 | `KernelSlotView.__setattr__` triggers 5 persistence side effects — no read-only view | Bridge | Medium |
