Iter 49. Ships the crate's first README — genuinely missing artifact.
crates.io renders this file; the rendered page is what downstream
operators see when they `cargo doc --open` or browse the registry.
Added:
- v2/crates/wifi-densepose-bfld/README.md (~135 lines):
* Three structural invariants (I1/I2/I3) table with enforcement
mechanism per invariant
* Quickstart snippet: in-process consumer (BfldPipeline::process)
* Quickstart snippet: production worker (BfldPipelineHandle +
bootstrap helpers)
* Feature flag matrix (std / serde-json / mqtt / soul-signature)
* Two runnable example invocations
* Testing matrix (no_default / default / mqtt)
* Companion artifacts pointer (ADRs, research bundle, HA
blueprints, CI workflow)
* ADR cross-reference table (ADR-118 through ADR-123)
* BFLD_MQTT_BROKER env-var doc for live mosquitto opt-in
- v2/crates/wifi-densepose-bfld/Cargo.toml:
readme = "README.md"
(so crates.io picks it up on publish)
- v2/crates/wifi-densepose-bfld/tests/crate_readme.rs (8 tests):

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 — crates.io / cargo doc landing
page now exists. Operators encountering wifi-densepose-bfld for the
first time get the three structural invariants, quickstart snippets
for both deployment patterns, feature matrix, and ADR map without
having to read source.
Test config:
- cargo test --no-default-features → 101 passed (crate_readme cfg-out)
- cargo test → 327 passed (319 + 8)
Out of scope (next iter target):
- PR-readiness pivot. CHANGELOG, witness bundle, AC closeout table.
External-resource-gated work (KIT BFId, Pi5/Nexmon) still skipped.

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
first three topics:
ruview/seed-handle-demo/bfld/availability
homeassistant/binary_sensor/seed-handle-demo_bfld_presence/config
homeassistant/sensor/seed-handle-demo_bfld_motion/config
last three topics:
ruview/seed-handle-demo/bfld/confidence/state
ruview/seed-handle-demo/bfld/identity_risk/state
ruview/seed-handle-demo/bfld/availability
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):

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

Iter 47. Ships the operator-facing quickstart as doc-as-code. Three
goals:
1. New operators reading the crate get a 50-line working example
instead of having to assemble pipeline + config + hasher + inputs
+ embedding + JSON publish themselves.
2. CI proves the example COMPILES and RUNS end-to-end via a
separate test that re-executes the same flow inline.
3. The example output is the canonical BfldEvent JSON, demonstrating
every documented field (presence/motion/count/conf/zone/class/
identity_risk_score/rf_signature_hash) for a typical Anonymous
class publish.
Added:
- v2/crates/wifi-densepose-bfld/examples/bfld_minimal.rs (~70 LOC):
* Per-site secret salt
* BfldPipeline::new(BfldConfig::new(...).with_signature_hasher(...))
* SensingInputs with low-risk factors so the gate emits
* IdentityEmbedding from a deterministic ramp
* pipeline.process(...).ok_or(...) for the gate-drop case
* event.to_json() printed to stdout
* Run command in the doc comment:
cargo run -p wifi-densepose-bfld --example bfld_minimal
- v2/crates/wifi-densepose-bfld/tests/example_minimal.rs (4 tests):
minimal_example_documents_the_operator_quickstart_flow
(asserts file contains BfldPipeline, SignatureHasher,
SensingInputs, IdentityEmbedding, BfldConfig, .process(,
to_json — catches doc drift if the example removes a key
symbol)
minimal_example_carries_run_instructions_in_doc_comments
(the cargo run --example line must be present)
minimal_example_flow_produces_valid_json_with_documented_fields
*** Re-runs the example flow inline and asserts every
documented JSON field appears in the output ***
example_returns_box_dyn_error_for_main_signature
(canonical Rust-example main signature)
- v2/crates/wifi-densepose-bfld/Cargo.toml:
[[example]] name = "bfld_minimal", required-features = ["serde-json"]
so `cargo test --no-default-features` doesn't try to build the
example (which needs to_json gated on serde-json).
Example run output (sanity check before commit):
{"type":"bfld_update","node_id":"seed-example","timestamp_ns":...,
"presence":true,"motion":0.42,"person_count":1,"confidence":0.91,
"privacy_class":"anonymous","identity_risk_score":0.0016000001,

ACs progressed:
- ADR-118 §2.1 documentation surface — first operator-facing example
shipped as part of the crate. Discoverable via
`cargo run --example bfld_minimal` and verified via cargo test.

Iter 23. Production Publish trait impl using rumqttc 0.24 (same crate
version + use-rustls feature pinning as wifi-densepose-sensing-server,
so both publishers can share broker connection posture).
Added:
- rumqttc = "0.24" optional dep (default-features = false, use-rustls)
- New `mqtt` cargo feature: ["std", "dep:rumqttc"]
- src/rumqttc_publisher.rs (gated on `feature = "mqtt"`):
* RumqttPublisher wrapping rumqttc::Client + QoS + retain flag
* RumqttPublisher::new(client, qos) const constructor
* with_retain(bool) builder for availability-style topics
* RumqttPublisher::connect(opts, capacity) -> (Self, Connection)
Returns the unpumped Connection — caller spawns a thread that
iterates connection.iter() to drive the MQTT protocol. Default
QoS is AtLeastOnce (HA-DISCO recommendation for state topics).
* impl Publish with Error = rumqttc::ClientError
- pub use RumqttPublisher from lib.rs
tests/rumqttc_publisher_smoke.rs (7 named tests, all green, gated on mqtt):
rumqttc_publisher_constructs_without_broker
(uses 127.0.0.1:1 — reserved port refuses immediately; no hang)
with_retain_builder_yields_a_publisher
publish_queues_message_without_blocking_on_broker_state
*** Critical property: rumqttc's sync Client::publish queues into
an unbounded channel; publish_event returns Ok without round-
tripping to the (offline) broker. The queued packet only sends
if a thread iterates Connection::iter(). ***
restricted_event_publishes_four_messages_through_rumqttc
(class 3 + no zone: presence/motion/count/confidence — 4 topics)
publisher_trait_object_is_constructible
(Box<dyn Publish<Error = rumqttc::ClientError>> works)
direct_publish_call_through_trait_object
default_qos_is_at_least_once_via_connect
ACs progressed:
- ADR-122 §2.2 broker integration — production publisher now wired,
matching the sensing-server's TLS / version posture. The two
crates can share a single broker connection if an operator wants
both publishers in the same process.
- ADR-122 AC4 still enforced — publish_event's class-gated routing
is upstream of rumqttc, so no broker-level config can leak Raw frames.
Test config:
- cargo test --no-default-features → 72 passed (mqtt feature off)
- cargo test → 169 passed (mqtt feature off)
- cargo test --features mqtt --test rumqttc_publisher_smoke → 7 passed
- With --features mqtt: 169 + 7 = 176 total
Out of scope (next iter target):
- mosquitto integration test (env-gated MQTT_BROKER=tcp://localhost:1883):
* spawn a thread iterating Connection::iter()
* publish a BfldEvent
* subscribe in the test, await SubAck per the workspace memory note
`feedback_mqtt_integration_test_patterns`
* assert the topics received match render_events output
- BfldPipelineHandle: Arc<Mutex<BfldPipeline>> with a thread that pumps
inbound (inputs, embedding) → process → publish_event(&rumqttc_pub, &event)
for a single-call "set up MQTT publisher and walk away" API.

Iter 15. Lands ADR-120 §2.3 — the cryptographic foundation of invariant
I3 ("cross-site identity correlation is impossible"). rf_signature_hash
is now derived from a per-site secret and a daily epoch, so two nodes
observing the same physical person produce uncorrelated 256-bit digests.
Added (no_std-compatible):
- blake3 = "1.5", default-features = false (no_std, no SIMD by default)
- src/signature_hasher.rs:
* Constants SECONDS_PER_DAY (86_400), SITE_SALT_LEN (32), RF_SIGNATURE_LEN (32)
* SignatureHasher { site_salt: [u8; 32] } with new(salt) const ctor
* compute(day_epoch, &features) -> [u8; 32] (BLAKE3 keyed mode)
* compute_at(unix_secs, &features) -> [u8; 32] convenience
* day_epoch_from_unix_secs(unix_secs) -> u32 helper (floor(t / 86400))
- pub use SignatureHasher, RF_SIGNATURE_LEN, SITE_SALT_LEN from lib.rs
tests/signature_hasher.rs (8 named tests, all green):
deterministic_under_identical_inputs
different_site_salts_produce_different_hashes
different_day_epochs_rotate_the_hash
different_features_produce_different_hashes
output_length_is_32_bytes
day_epoch_from_unix_secs_matches_floor_division
(covers 0, 86_399, 86_400, and the 1.7e9 modern timestamp)
compute_at_matches_compute_with_derived_day
cross_site_hamming_distance_is_statistically_high
*** ADR-120 §2.7 AC2 acceptance test ***
Runs 100 trials with distinct (salt_a, salt_b) pairs observing
identical features, computes per-trial Hamming distance, asserts
mean >= 120 bits and min >= 80 bits. Empirically lands at ~128 bits
mean (the expected value for two independent 256-bit hashes), with
no trial below 80 bits — i.e., zero suspicious near-collisions.
ACs progressed:
- ADR-120 §2.7 AC2 — structurally enforced cross-site isolation, now
proven empirically by the Hamming-distance test. This is the
cryptographic half of invariant I3 in code, not just docs.
- ADR-118 invariant I3 — first runtime witness that two sites with
independent site_salts cannot correlate the same person's signature.
Test config:
- cargo test --no-default-features → 72 passed (64 + 8; signature_hasher is no_std)
- cargo test → 117 passed (109 + 8)
Out of scope (next iter target):
- Wire SignatureHasher into BfldEmitter: replace caller-supplied
rf_signature_hash with hasher.compute_at(ts, &features) so the
pipeline produces correct hashes end-to-end.
- IdentityFeatures canonical-bytes encoder so callers don't need to
hand-serialize per-feature representations.

Iter 13. Lands ADR-121 §2.1 (output event) + ADR-122 §2.1 (field-gating
policy). BfldEvent collapses the GateAction-driven sensing pipeline
into the canonical wire-format publishable on MQTT.
Added:
- serde (workspace, derive feature, optional) + serde_json (workspace, optional) deps
- New crate feature `serde-json` (default-on; requires `std`)
- src/event.rs (gated on `feature = "std"`):
* BfldEvent struct with all sensing + identity-derived fields
* with_privacy_gating(...) constructor that applies field-gating policy:
class < Restricted (3): identity_risk_score + rf_signature_hash kept
class >= Restricted (3): both nulled to None
* apply_privacy_gating() — idempotent in-place masking
* to_json() -> Result<String, serde_json::Error> (gated on serde-json)
* Custom ser_privacy_class serializer emits lowercase names
("anonymous", "restricted", etc.) per the BFLD JSON spec
* skip_serializing_if = "Option::is_none" on identity-derived fields so
privacy-gated events are observationally indistinguishable from
events that never had the field set
- pub use BfldEvent from lib.rs
tests/event_privacy_gating.rs (9 named tests, all green):
anonymous_event_retains_identity_risk_and_hash
restricted_event_strips_identity_fields (class 3 → None)
apply_privacy_gating_is_idempotent
event_type_is_always_bfld_update (parameterized over 3 classes)
json::json_round_trip_emits_type_field_first_or_last_but_present
json::anonymous_json_includes_identity_fields
json::restricted_json_omits_identity_fields_entirely
(asserts the JSON string does NOT contain identity_risk_score or
rf_signature_hash, verifying skip_serializing_if works as intended)
json::privacy_class_serializes_to_lowercase_name
json::zone_id_none_is_omitted_from_json
ACs progressed:
- ADR-121 AC6 (identity_risk score absent at class 3) — structurally
enforced by with_privacy_gating + skip_serializing_if combination.
- ADR-122 AC1 — JSON shape matches the HA-DISCO publishable event
contract; identity fields can be reliably stripped by privacy_class.
- ADR-118 AC5 — privacy_mode = engaged maps to PrivacyClass::Restricted
with no identity fields in the published event.
Test config:
- cargo test --no-default-features → 64 passed (unchanged; event cfg-out)
- cargo test → 102 passed (93 + 9)
Out of scope (next iter target):
- Emitter struct that wires GateAction + privacy class + sensing inputs
into BfldEvent construction (ADR-118 §2.1 pipeline diagram).
- MQTT topic publisher (ADR-122 §2.2) — depends on a runtime (tokio).

Land P1 of the BFLD rollout — the wire-format primitives:
- New workspace member: v2/crates/wifi-densepose-bfld
- PrivacyClass enum (Raw/Derived/Anonymous/Restricted) with allows_network()
and allows_matter() const helpers reflecting ADR-120 §2.2 and ADR-122 §2.4
- BfldFrameHeader (#[repr(C, packed)]) per ADR-119 §2.1
- BFLD_MAGIC = 0xBF1D_0001, BFLD_VERSION = 1
- BfldError variants for InvalidMagic / UnsupportedVersion / Crc / PrivacyViolation
- soul-signature cargo feature (gated, default OFF) per ADR-118 §1.4
- Compile-time size assertion via static_assertions::const_assert_eq!
- 3 acceptance tests in tests/frame_header_size.rs (all pass)
Bug fix:
- ADR-119 AC1 claimed BfldFrameHeader is 40 bytes. Actual packed layout sums
to 86 bytes. Updated AC1 and §2.1 prose to match. const_assert in frame.rs
pins the value structurally — a future field addition that breaks the size
fails to compile.
Out of scope for this iter (deferred to later P1 commits):
- Field-level missing-docs warnings (21) — addressed alongside accessor helpers
- Payload section parsing — needs the section-length prefix tests
- Round-trip serialize/parse — covered by a fixture-based test in the next iter
cargo test -p wifi-densepose-bfld --no-default-features → 3 passed, 0 failed
