Iter 48. Ships the production-recommended operator example: full
lifecycle through the worker-thread handle. Companion to iter-47's
minimal example which uses BfldPipeline::process directly. The
handle example demonstrates the multi-thread pattern operators
actually deploy with HA + MQTT.
Lifecycle demonstrated in the example:
1. publish_availability_online (retained → HA marks device online)
2. publish_discovery (retained → HA auto-creates 6 BFLD entities)
3. BfldPipelineHandle::spawn (worker owns gate + ring + hasher)
4. handle.send(input) per BFI frame (worker process + publish)
5. handle.shutdown() (clean worker join)
6. publish_availability_offline (explicit graceful disconnect)
Example output (verified pre-commit):
bootstrap: 1 availability + 6 discovery payloads
total messages published: 33

Added:
- v2/crates/wifi-densepose-bfld/examples/bfld_handle.rs (~110 LOC):
* Documents the 6-phase lifecycle with inline comments
* Pointer to RumqttPublisher::connect_with_lwt for prod use
* 5 sensing frames × 5 state topics = 25 per-frame messages
- v2/crates/wifi-densepose-bfld/tests/example_handle.rs (4 named tests):
handle_example_documents_full_lifecycle_phases
(doc drift guard: 8 operator-facing symbols must appear)
handle_example_carries_run_instructions_and_prod_pointer
(cargo run line + RumqttPublisher pointer present)
handle_example_lifecycle_produces_expected_message_counts
*** Re-executes full lifecycle inline; asserts total == 33,
first message payload == "online", last == "offline" ***
handle_example_returns_box_dyn_error_for_main_signature
- v2/crates/wifi-densepose-bfld/Cargo.toml:
[[example]] name = "bfld_handle", required-features = ["std"]
ADR-124 status (iter step 0 sibling check):
- docs/adr/ADR-124-rvagent-mcp-ruvector-npm-integration.md unchanged
at 431 lines. SENSE-BRIDGE scope remains orthogonal.
ACs progressed:
- ADR-118 §2.1 documentation surface — two runnable operator examples
now shipped (iter 47 minimal, iter 48 worker-thread). Together
they cover the two operator patterns: simple in-process consumer
(process + to_json) and the full HA-integration deployment
(handle + bootstrap + lifecycle).
- ADR-122 §2.1 + §2.2 + §2.6 — the worker example exercises every
layer of the HA-DISCO publish chain in one runnable file:
availability, discovery, state, graceful shutdown.
Test config:
- cargo test --no-default-features → 101 passed (example_handle cfg-out)
- cargo test → 319 passed (315 + 4)
Out of scope (next iter target):
- PR-readiness pivot still pending. External-resource-gated work
(KIT BFId, Pi5/Nexmon) still skipped.
