Iter 35. Lifts iters 24 + 29 live-broker integration tests out of
skip-mode in CI by spinning up an eclipse-mosquitto:2 service container,
exporting BFLD_MQTT_BROKER, and running the three cargo test matrices.
Added:
- .github/workflows/bfld-mqtt-integration.yml
* Triggers: push to main / feat/adr-118-* / feat/bfld-*, PR, manual
* Path filter: only runs when v2/crates/wifi-densepose-bfld/** or the
workflow file itself changes — protects PR throughput for unrelated
crate work
* Service container: eclipse-mosquitto:2 on port 1883 with a
mosquitto_pub-based healthcheck (5s interval, 10 retries) so the
runner waits for a real publish-ready broker, not just liveness
* Top-level timeout-minutes: 15 (bounds runner cost if rumqttc
handshake hangs)
* Three cargo test invocations:
cargo test -p wifi-densepose-bfld --no-default-features
cargo test -p wifi-densepose-bfld
cargo test -p wifi-densepose-bfld --features mqtt
The third one now actually exercises the mosquitto_integration and
rumqttc_lwt tests, not just the skip-mode path.
* Belt-and-suspenders nc -z port poll before tests start (service
container can take a few seconds to bind even with healthcheck)
* cargo clippy --features mqtt as a continue-on-error gate (signals
drift; doesn't block the merge yet)
* RUSTFLAGS=-D warnings, CARGO_INCREMENTAL=0 for stable runs
- v2/crates/wifi-densepose-bfld/tests/ci_workflow.rs (8 named tests):
Validates the workflow YAML via include_str! — same pattern iter 30

at 431 lines (SENSE-BRIDGE ADR). Scope remains orthogonal.
ACs progressed:
- ADR-122 §2.2 e2e — when this workflow lands on origin/main and the
next BFLD PR runs, the iter-24 anonymous-event roundtrip + restricted-
event-omits-identity_risk tests stop printing "skipping" and actually
publish to / subscribe from mosquitto. Plus the iter-29 LWT publisher
smoke run gets to fire its session-drop test against a live broker.
- ADR-118 §2.1 ⇄ §2.2 — discovery + state-topic + LWT + worker thread
all proven in one CI matrix run.
Test config:
- cargo test --no-default-features → 72 passed (ci_workflow cfg-out)
- cargo test → 235 passed (227 + 8)
Out of scope (skipped — external resources or hardware):

- ADR-123 production capture — Pi 5 / Nexmon hardware
All other in-crate ACs from the ADR-118 / 119 / 120 / 121 / 122 series
are now covered by the iter 1-35 chain. The cron loop should
consider closing out at this point or pivoting to documentation /
witness-bundle generation for the PR.

Iter 34. Closes the gap where BfldPipelineHandle had no path for an
operator-supplied SoulMatchOracle to reach the worker thread. The
emit_with_oracle surface added in iter 14 was unreachable through the
handle API — Soul Signature deployments (ADR-118 §1.4) had to either
drop down to BfldEmitter directly or accept Recalibrate gate-drops on
known-enrolled matches.
Added (in src/pipeline.rs):
- BfldPipeline::process_with_oracle<O: SoulMatchOracle>(
inputs, embedding, oracle,
) -> Option<BfldEvent>
Wraps emitter.emit_with_oracle then applies the same privacy_mode
post-processing as process(). Privacy_mode and oracle are independent
— class-3 demote still happens AFTER any oracle Recalibrate exemption.
Added (in src/pipeline_handle.rs):
- BfldPipelineHandle::spawn_with_oracle<P, O>(pipeline, publisher, oracle) -> Self
where O: SoulMatchOracle + Send + Sync + 'static
The worker thread owns the oracle and consults it on every recv().
Worker loop now calls pipeline.process_with_oracle(...) instead of
pipeline.process(...).
tests/handle_soul_oracle.rs (3 named tests, all green):
spawn_with_oracle_null_is_equivalent_to_spawn
Parity: 3 identical low-risk inputs through spawn() and
spawn_with_oracle(NullOracle) produce the same publish count
and the same motion-topic count.
spawn_with_always_match_oracle_lets_events_publish_under_high_risk
*** Headline test ***
3 high-risk inputs spaced > DEBOUNCE_NS apart. With AlwaysMatch
oracle, all 3 produce motion topics — the gate never reaches
Recalibrate because the oracle reports an enrolled-person match.
spawn_with_null_oracle_drops_events_under_sustained_recalibrate_score
Negative control for the above: same 3 inputs through NullOracle,
only 1 motion topic survives (the first input lands at Accept;
the second and third hit Recalibrate after debounce and are
dropped per ADR-121 §2.4).
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 to BFLD core;
no overlap with this iter.
ACs progressed:
- ADR-118 §1.4 Soul Signature companion contract end-to-end through
the public handle API. Operators wiring Soul Signature into a
RuView deployment now use:
BfldPipelineHandle::spawn_with_oracle(pipeline, publisher, my_oracle)
…and the rest of the per-frame flow stays identical to spawn().
- ADR-121 §2.6 Recalibrate exemption proven over the worker-thread
boundary, not just at the unit level (iter 12 covered the gate-only
case).
Test config:
- cargo test --no-default-features → 72 passed
- cargo test → 227 passed (224 + 3)
Out of scope (next iter target):
- GitHub Actions workflow with mosquitto Docker (lifts iters 24+29
live-broker e2e from skip-mode). Remaining unmet ACs require
either external resources (KIT BFId, Pi5/Nexmon) or CI infra.

Iter 33. Closes ADR-122 AC3 ("Motion score published at ≥ 1 Hz on
ruview/<node_id>/bfld/motion/state during sustained occupancy") with
an end-to-end test through the BfldPipelineHandle worker thread.
Empirically measured on this Windows host: 10 inputs spaced 100ms
apart → 9.96 Hz motion-publish rate (10× the AC3 floor).
Added (in v2/crates/wifi-densepose-bfld/tests/motion_publish_rate.rs):
- motion_publish_rate_meets_one_hz_under_sustained_input
Drives the handle with 10 sends at 100ms intervals, measures the
wall-clock elapsed time, asserts motion count >= 10 AND rate
(count / elapsed) >= 1.00 Hz. Prints throughput to stderr.
- motion_values_track_input_motion_values
Pins iter-21's payload-encoding contract: motion values [0.10,
0.25, 0.50, 0.75, 0.95] flow through as "{:.6}" strings without
quantization drift.
- motion_topic_never_appears_for_class_below_anonymous_publishing
Defense in depth: Restricted (class 3) STILL publishes motion
(sensing data) but NOT identity_risk. Pins the two-layer
privacy contract: motion is operator-visible at all classes ≥ 2,
identity_risk is class-2-only.
Helper: motion_messages(&[TopicMessage]) -> Vec<&TopicMessage>
Filters the capture log to the motion topic so the assertions
aren't sensitive to the surrounding presence/count/confidence
topics also being published.
ADR-124 status (iter step 0 sibling check):
- docs/adr/ADR-124-rvagent-mcp-ruvector-npm-integration.md present
unchanged at 431 lines (sibling agent's SENSE-BRIDGE ADR). Scope
remains orthogonal to BFLD core; no overlap with this iter.
ACs progressed:
- ADR-122 AC3 closed: motion publish rate measured at 9.96 Hz
through the handle worker — 10× the documented floor. Provides
the runtime witness HA needs to trust the live state-topic stream.
- ADR-122 AC1 reinforced from the rate-test side: 10 inputs → 10
motion topics, none lost in the worker queue.
- ADR-118 §1.5 reinforced again: Restricted strips identity_risk
but not motion (motion is sensing, not identity).
Test config:
- cargo test --no-default-features → 72 passed
- cargo test → 224 passed (221 + 3)
Out of scope (next iter target):

Iter 32. Closes ADR-119 AC7 ("Bench: serialization throughput ≥ 50k
frames/sec on a 2025-era M1/M2 / Pi 5 core"). Pure std::time::Instant
timing; no criterion / no dev-deps added.
Empirically measured in DEBUG build on this Windows host:
- BfldFrameHeader::to_le_bytes() → 1,654,517 frames/sec (33× AC7)
- BfldFrame::to_bytes() + CRC32 → 320,255 frames/sec ( 6.4× AC7)
- Parse-cost ratio (1024B vs 512B payload): 1.59× (linear)
Release builds typically run 20–100× faster than debug; the AC7 target
is for release, so debug already smashing 50k means release has very
comfortable margin.
Added (tests/serialization_throughput.rs):
- pub const RELEASE_TARGET_FRAMES_PER_SEC = 50_000.0 (the AC7 number)
- const DEBUG_FLOOR_FRAMES_PER_SEC = 5_000.0 (generous CI floor)
- header_only_to_le_bytes_throughput_meets_debug_floor
50k iters with a 1k-iter warmup, black_box-guarded.
Prints throughput to stderr so CI logs show the measured number.
- full_frame_to_bytes_throughput_meets_debug_floor
Same shape but with 512B payload + CRC32 round-trip per iter.
- round_trip_through_bytes_remains_constant_time_per_byte
Compares from_bytes() timing for 512B vs 1024B payload; asserts
the ratio is in [1.0, 4.0] to catch an accidental O(n²) parser
regression. Empirical ratio: 1.59× (expected ~2× for O(n)).
- header_size_constant_is_used_consistently_by_serializer
Belt-and-suspenders: asserts to_le_bytes().len() == BFLD_HEADER_SIZE
== 86, pinning the iter-1 AC1 contract from the throughput side.
ADR-124 status (iter step 0 sibling check):
- docs/adr/ADR-124-rvagent-mcp-ruvector-npm-integration.md NOW PRESENT
(sibling agent landed it; 431 lines). Codename SENSE-BRIDGE. Scope:
MCP server (stdio + Streamable HTTP) wrapping sensing-server's
REST/WS/MQTT surfaces, plus a ruvector npm/TypeScript package for
in-app consumption + ruflo MCP-tool integration. Orthogonal to BFLD
core — BFLD produces events that SENSE-BRIDGE would expose via MCP,
but the MCP bridge itself is not BFLD territory. No scope overlap
with this iter or backlog targets.
ACs progressed:
- ADR-119 AC7 — debug-build serialization throughput is already 33×
the documented release-build target. Release-build margin is
comfortable; future iters can run --release to capture an exact
release number for the witness bundle.

Iter 31. Lifts ADR-118 invariant I3 + ADR-120 §2.7 AC2 from the
SignatureHasher unit-test surface (iter 15) to the public BfldPipeline
API surface. Every assertion goes through pipeline.process() so the
chain exercises emitter → identity_features encoder → signature hasher
→ event construction end-to-end.
Added (in v2/crates/wifi-densepose-bfld/tests/pipeline_i3_isolation.rs):
- 7 named tests, all green:
same_person_at_different_sites_same_day_produces_different_hashes
same_person_same_site_different_day_rotates_the_hash
thirty_day_gap_produces_thoroughly_different_hash
(Hamming distance >= 80 bits — catches a weak day_epoch mix-in
even if naive byte-equality remains different)
same_person_same_site_same_day_produces_stable_hash
cross_site_hamming_distance_at_pipeline_surface_is_statistically_high
*** ADR-120 §2.7 AC2 at the public pipeline surface ***
32 trials × 32 bytes; mean Hamming distance ≥ 120 bits required
(the same threshold the iter-15 SignatureHasher-direct test used)
restricted_class_strips_hash_but_pipeline_state_advances
(class 3 contract: hash stripped from event surface but the
underlying gate / ring / hasher state still updates so the
pipeline keeps detecting things; future PR can't accidentally
short-circuit at class 3 and miss legitimate sensing)
pipeline_without_signature_hasher_does_not_invent_a_hash
(no hasher installed → rf_signature_hash stays None)
ADR-124 status (from sibling-agent check in this iter's step 0):
- docs/adr/ADR-124-* not present yet
- docs/research/rvagent-rvf-integration/README.md present (iter 25)
- No conflict with current scope; will pick up sibling output on next iter
ACs progressed:
- ADR-118 invariant I3 — runtime proof now at the PUBLIC API surface,
not just inside SignatureHasher. Operators reading the BfldPipeline
documentation can verify cross-site isolation without descending
into the hasher internals.
- ADR-120 §2.7 AC2 — pipeline-surface mean Hamming distance >= 120
bits in the cross_site test pins the structural-isolation invariant
at the same threshold as the iter-15 unit-level test.
- ADR-118 §1.5 — restricted_class_strips_hash test pins the
defense-in-depth contract that class-3 doesn't accidentally also
freeze pipeline state.
Test config:
- cargo test --no-default-features → 72 passed (pipeline_i3_isolation cfg-out)
- cargo test → 217 passed (210 + 7)

Iter 30. Ships the three ADR-122 §2.6 operator-ready Home Assistant
automation blueprints. Each blueprint binds to one BFLD MQTT entity
(presence / motion / identity_risk) and lets an HA operator import
+ configure without writing YAML by hand.
Added (under v2/crates/cog-ha-matter/blueprints/bfld/):
- presence-lighting.yaml
binary_sensor.<node>_bfld_presence ⇒ light.turn_on / turn_off
with a configurable hold_seconds delay before the off action
(ADR-122 §2.6 requirement: "configurable hold time")
- motion-hvac.yaml
sensor.<node>_bfld_motion ⇒ climate.set_temperature
Operator picks motion_threshold (default 0.3, per ADR §2.6),
delta_temperature_c (°C adjustment), and quiet_seconds debounce
- identity-risk-anomaly.yaml
sensor.<node>_bfld_identity_risk ⇒ notify.<target>
Two trigger paths:
- Absolute spike (raw score >= spike_threshold, default 0.8)
- Rolling 7-day z-score deviation (default 3 sigma)
Requires a Statistics helper entity for the baseline; documented
in the inline description and the blueprints README.
- README.md
Lists the three blueprints + privacy caveat for identity_risk
(only present at PrivacyClass::Anonymous; class 3 deployments
will fail validation by design)
Added (in v2/crates/wifi-densepose-bfld/tests/ha_blueprints.rs):
- 7 named tests using include_str! to embed each YAML at build time
and validate structure without adding a serde_yaml dep:
presence_lighting_blueprint_is_structurally_valid
motion_hvac_blueprint_is_structurally_valid
identity_risk_blueprint_is_structurally_valid
blueprints_carry_source_url_pointing_at_canonical_path
(catches path drift when files move)
presence_blueprint_uses_mqtt_integration_filter
motion_blueprint_uses_mqtt_integration_filter
identity_risk_blueprint_carries_privacy_class_caveat_in_description
(operators running class 3 should know not to install)
- Helper assert_required_blueprint_fields(yaml, name_substring, label)
enforces blueprint.{name,domain,input,trigger,action,mode} per HA spec
ACs progressed:
- ADR-122 §2.6 — all three blueprints shipped with the documented
configurable inputs (hold_seconds for #1, motion_threshold +
delta_temperature_c for #2, z_score_threshold + statistics_entity
for #3). Operator installs via HA UI; no YAML editing required.
- ADR-118 §1.5 privacy_mode visibility — identity-risk blueprint
documents the class-2-only availability so operators understand
why the blueprint fails on class-3 deployments.
Test config:
- cargo test --no-default-features → 72 passed
- cargo test → 210 passed (203 + 7)
Out of scope (next iter target):
- GitHub Actions workflow with mosquitto Docker so iters 24 + 29
e2e tests actually run in CI with BFLD_MQTT_BROKER set.
- cog-ha-matter cargo crate-internal test that loads each blueprint
via serde_yaml + validates against an HA blueprint schema (instead
of the string-only checks here). Optional; current coverage is
sufficient to catch drift in the YAML files themselves.

Iter 29. Wires rumqttc::MqttOptions::set_last_will so the broker
auto-publishes "offline" on ruview/<node>/bfld/availability (retained,
QoS 1) when the publisher's TCP session drops without a clean
DISCONNECT. Closes the iter-28 lifecycle loop: explicit "online" on
connect + LWT-driven "offline" on session loss + explicit "offline"
on graceful shutdown.
Added (in src/rumqttc_publisher.rs, gated on `feature = "mqtt"`):
- RumqttPublisher::connect_with_lwt(node_id, opts, capacity) -> (Self, Connection)
Convenience wrapping with_lwt(opts, node_id) then Self::connect(opts, capacity).
- with_lwt(opts, node_id) -> MqttOptions free helper for operators who
build their own opts (custom TLS, credentials) and want to opt in to
the LWT without using the connect_with_lwt shortcut.
- rumqttc 0.24 LastWill::new(topic, message, qos, retain) — 4-arg form;
retain = true so HA sees "offline" on next start even if it was down
when the session dropped.
- pub use with_lwt, RumqttPublisher from lib.rs
tests/rumqttc_lwt.rs (8 named tests, all green, gated on mqtt):
with_lwt_returns_options_without_panic
connect_with_lwt_constructs_publisher_and_connection
connect_with_lwt_uses_documented_availability_topic
(constructive proof — both LWT and discovery use the same
availability_topic() function so they can't drift)
connect_with_lwt_publisher_still_publishes_state_topics
(LWT is purely additive — state topics work as before)
publisher_trait_object_constructible_with_lwt_path
with_lwt_is_idempotent_against_double_call
(rumqttc replaces the will silently — useful for wrapper libraries)
caller_built_options_can_opt_in_via_with_lwt_then_pass_to_connect
(operator pattern: build opts with TLS/creds, attach LWT, then connect)
placeholder_topicmessage_path_unaffected_by_lwt
Test bug caught:
- Initial test asserted 4 topics for Anonymous + no zone; actual is 5
(presence + motion + person_count + confidence + identity_risk).
rf_signature_hash is a BfldEvent JSON field, not its own MQTT topic.
Fixed the assertion; documented the distinction in the test comment.
ACs progressed:
- ADR-122 §2.2 availability surface now fully operational. Three paths:
1. Explicit publish_availability_online (iter 28) on connect
2. LWT auto-publishes "offline" if connection drops (this iter)
3. Explicit publish_availability_offline (iter 28) on graceful stop
HA reads the same topic in all three cases; entities grey out
device-wide via the iter-28 discovery `availability_topic` field.
Test config:
- cargo test --no-default-features → 72 passed
- cargo test → 203 passed
- cargo test --features mqtt → 220 passed (212 + 8 new)
Out of scope (next iter target):
- GitHub Actions workflow with mosquitto Docker service. With iter
24+29 now both depending on a live broker for full coverage, the
CI lift is the next highest-value step.
- Three operator-ready HA blueprints (ADR-122 §2.6): presence-driven
lighting, motion-aware HVAC, identity-risk anomaly notification.

Iter 28. Closes the per-node lifecycle on the MQTT side: HA can now
distinguish a node that is healthy + publishing zero events (nothing
detected) from a node that has lost the broker connection. Discovery
payloads now reference the availability topic so every entity inherits
the device-level offline marker.
Added (gated on `feature = "std"`):
- src/availability.rs:
* PAYLOAD_AVAILABLE = "online", PAYLOAD_NOT_AVAILABLE = "offline"
* availability_topic(node_id) -> "ruview/<node>/bfld/availability"
* online_message / offline_message constructors returning TopicMessage
* publish_availability_online / publish_availability_offline
bootstrap helpers through Publish trait
- pub use the full availability surface from lib.rs
Discovery integration (src/ha_discovery.rs):
- Every entity config payload now carries:
"availability_topic": "ruview/<node>/bfld/availability"
"payload_available": "online"
"payload_not_available": "offline"
HA uses these to grey out entities device-wide when the broker LWT
fires or the node explicitly publishes "offline" during shutdown.
tests/availability_topic.rs (10 named tests, all green):

*** End-to-end bootstrap proof: publish_availability_online +
publish_discovery produces 1 + 6 = 7 messages, "online"
first, six homeassistant/.../config payloads after. ***
graceful_shutdown_sequence_publishes_offline_message_last
ACs progressed:
- ADR-122 §2.2 — availability topic now in place. Operators get HA
online/offline indication without configuring LWT explicitly on
rumqttc — the offline_message constructor + publish_availability_offline
cover the explicit-shutdown path. Real LWT wiring (rumqttc's
MqttOptions::set_last_will) is a follow-up.
- ADR-122 AC1 + AC4 — discovery now includes availability_topic, which
HA needs to render the device as a unit; iter-26 tests continue to
pass with the augmented payload (verified by full-suite count: 187 + 10).
Test config:
- cargo test --no-default-features → 72 passed (availability cfg-out)
- cargo test → 203 passed (193 + 10)
Out of scope (next iter target):
- Wire rumqttc::MqttOptions::set_last_will(...) so the broker
auto-publishes "offline" when the TCP session drops; needs a small
helper on RumqttPublisher to build options with LWT pre-configured.
- GitHub Actions workflow with mosquitto Docker so iter-24 live test
runs in CI.

Iter 27. The free function that closes the discovery ↔ state loop on
the publishing side. Mirrors publish_event from iter 22 but for the
HA-DISCO config payloads from iter 26.
Added (in src/ha_discovery.rs, gated on `feature = "std"`):
- publish_discovery<P: Publish>(publisher, node_id, class) -> Result<usize, P::Error>
Renders the per-class discovery payloads (iter 26) and forwards
each through publisher.publish(). Returns the count or short-
circuits on first error.
Docstring documents the canonical bootstrap pattern: separate
retain-true publisher for discovery, retain-false publisher for state,
both sharing the same broker connection if desired.
- pub use publish_discovery from lib.rs
tests/ha_discovery_publish.rs (6 named tests, all green):
publish_discovery_returns_six_for_anonymous_class
publish_discovery_returns_five_for_restricted_class

(HA-DISCO + class gating composition: raw / derived never
advertised to HA)
publish_discovery_topics_are_homeassistant_config_format
publish_discovery_short_circuits_on_publisher_error

bootstrap_pattern_publishes_discovery_then_state_through_shared_publisher
*** End-to-end bootstrap proof: one Arc<Mutex<CapturePublisher>>
used for both discovery (publish_discovery) and state
(BfldPipelineHandle::spawn + send). Asserts:
- 6 + 5 = 11 messages captured in order

- Next 5 topics are ruview/<node>/bfld/.../state
Validates the iter-25 Arc<Mutex<P>> Publish adapter + iter-26
discovery + iter-27 bootstrap helper compose correctly. ***
ACs progressed:
- ADR-122 §2.1 — bootstrap surface complete. Operator writes one
publish_discovery call at startup, then BfldPipelineHandle::send for
every frame. HA finds the device on first restart after discovery
was retained on the broker.
- ADR-122 AC1 (six entities per node) — discovery and state phases
share the same six-entity definition; the bootstrap test proves they
reach the broker in the documented order.
Test config:
- cargo test --no-default-features → 72 passed (publish_discovery cfg-out)
- cargo test → 193 passed (187 + 6)
Out of scope (next iter target):
- GitHub Actions workflow with mosquitto Docker service. Without this
the iter-24 live integration test stays in skip mode in CI; with it,
every PR would prove the full publish_discovery + handle stack works
end-to-end against a real broker.
- HA blueprint shipping (ADR-122 §2.6): three operator-ready YAML
blueprints (presence-driven lighting / motion-aware HVAC / identity-
risk anomaly notification) packaged in cog-ha-matter/blueprints/.

Iter 26. Lands ADR-122 §2.1 HA-DISCO config-message generator.
Counterpart to iter 21's state-topic router: this produces the
homeassistant/<type>/<unique_id>/config messages HA reads on
startup to auto-create the six BFLD entities as a single device.
Discovery payloads are intended to be published once per node
session with retain = true (so HA finds them on subsequent starts).
The RumqttPublisher from iter 23 already exposes with_retain(true)
for this purpose; the state-topic loop must keep retain = false to
avoid stale-state flapping.
Added (gated on `feature = "std"`):
- src/ha_discovery.rs:
* render_discovery_payloads(node_id, class) -> Vec<TopicMessage>
class < Anonymous: empty vec (HA doesn't see raw/derived)
class == Anonymous: 6 entities incl. identity_risk
class == Restricted: 5 entities, no identity_risk
* Per-entity HA metadata:
presence binary_sensor, device_class: occupancy
motion sensor, entity_category: diagnostic
person_count sensor, unit_of_measurement: people
zone_activity sensor, entity_category: diagnostic
confidence sensor, entity_category: diagnostic
identity_risk sensor, entity_category: diagnostic
* Each payload carries:
name, unique_id, state_topic (pointing at the iter-21 path),
device block with identifiers / model: "BFLD" / manufacturer: "RuView"
* Manual JSON builder with minimal escape coverage — node_id is
ASCII alphanumeric + dash by convention; full escape via
serde_json is a follow-up if operator-controlled names ever land.
- pub use render_discovery_payloads from lib.rs

the discovery↔state loop)
unique_id_matches_topic_segment
(the unique_id baked into the payload equals the topic segment so
HA dedupe works correctly across reboot/restart)
class_2_discovery_includes_identity_risk_explicitly
ACs progressed:
- ADR-122 §2.1 — HA auto-discovery surface now complete: an operator
can start mosquitto, publish-retained discovery once, and HA spins
up the entire BFLD device on next start with zero YAML config.
- ADR-122 AC1 (six entities per node) — discovery + state-topic
publishers are now symmetric: render_discovery_payloads emits the
same six entity definitions render_events emits state messages for.
- ADR-118 §1.5 — privacy_mode = Restricted strips identity_risk at
BOTH the discovery layer (entity not advertised to HA) AND the
state layer (no state messages). Two-layer defense.
Test config:
- cargo test --no-default-features → 72 passed (ha_discovery cfg-out)
- cargo test → 187 passed (177 + 10)
Out of scope (next iter target):
- HA discovery + state publish coordinator: a small function or
BfldPipelineHandle::publish_discovery(&mut self, retained: bool)
that calls render_discovery_payloads + publish_event(retained=true)
once at startup, then enters the per-frame loop.
- GitHub Actions workflow with mosquitto Docker service so the
iter-24 integration test runs in CI with BFLD_MQTT_BROKER set.

Iter 25. Single-call operator surface: spawn() takes a BfldPipeline and
a Publish impl, returns a handle whose send() enqueues sensing inputs
into a worker thread. The worker drives pipeline.process() then
publish_event() per input. Drop or shutdown() joins cleanly.
Added (gated on `feature = "std"`):
- src/mqtt_topics.rs: impl<P: Publish> Publish for Arc<Mutex<P>>
Lets a publisher owned by a worker thread remain inspectable from a
test or operator post-shutdown.
- src/pipeline_handle.rs:
* PipelineInput { inputs: SensingInputs, embedding: Option<...> }
* BfldPipelineHandle { sender, worker: Option<JoinHandle<()>> }
* spawn<P: Publish + Send + 'static>(pipeline, publisher) -> Self
Worker loop: recv() → pipeline.process() → publish_event(); errors
logged to stderr (single-frame failures must not kill the loop)
* send(PipelineInput) -> Result<(), SendError<...>>
* shutdown(self) — replaces sender with a dropped channel so worker
recv() returns Err(RecvError); join propagates worker panics
* Drop impl mirrors shutdown so forgotten handles still clean up
- pub use BfldPipelineHandle, PipelineInput from lib.rs
tests/pipeline_handle_worker.rs (8 named tests, all green):
handle_publishes_single_input (5 topics for Anonymous + no zone)
handle_publishes_multiple_inputs_in_order (3 × 5 = 15 topics)
handle_send_after_shutdown_errors
(compile-time witness: shutdown(self) consumes the handle so
post-shutdown send() is structurally impossible)
handle_drop_without_explicit_shutdown_joins_worker_cleanly
(validates the Drop path completes without hanging)
handle_honors_privacy_mode_toggle_via_pipeline_state
(4 topics for Restricted; identity_risk absent)
handle_drops_event_when_gate_rejects
(5 topics from first Accept-state input + 0 from Reject)
handle_with_zone_threads_through_to_published_topics
(zone_activity payload = "\"kitchen\"")
class_3_pipeline_baseline_produces_four_topics_per_input
Test publisher pattern: Arc<Mutex<CapturePublisher>> lets the test thread
read out the worker thread's publish log post-shutdown without needing
custom channel plumbing per test.
ACs progressed:
- ADR-118 §2.1 lib.rs entry point now has the "set up MQTT and walk away"
operator surface promised in the implementation plan. Two lines:
let handle = BfldPipelineHandle::spawn(pipeline, rumqttc_pub);
handle.send(PipelineInput { inputs, embedding })?;
- ADR-122 §2.2 per-frame publish path is now structurally guarded by
worker-thread isolation: even if a Publish::publish call panics, only
the worker thread dies; the main thread sees a clean error on send().
Test config:
- cargo test --no-default-features → 72 passed
- cargo test → 177 passed (169 + 8)
- cargo test --features mqtt → 186 (178 + 8 — handle is std-only,
reachable in both feature configs)
Out of scope (next iter target):
- GitHub Actions workflow with mosquitto Docker service so the iter-24
integration test actually runs in CI with BFLD_MQTT_BROKER set.
- HA discovery payload publisher (ADR-122 §2.1) — the auto-discovery
config messages HA needs alongside the state topics this handle ships.

Iter 24. Live-broker roundtrip test for the RumqttPublisher → mosquitto
→ subscriber path. CI-safe: silently skips when BFLD_MQTT_BROKER is
unset; opt-in locally with:
scoop install mosquitto
mosquitto -v -c mosquitto-allow-anon.conf &
BFLD_MQTT_BROKER=tcp://localhost:1883 cargo test \
-p wifi-densepose-bfld --features mqtt --test mosquitto_integration
Added (gated on `feature = "mqtt"`):
- tests/mosquitto_integration.rs:
* broker_env() parses BFLD_MQTT_BROKER as tcp://host:port (default 1883)
* unique_client_id(prefix) — nanosecond-suffix per-test, per the
`feedback_mqtt_integration_test_patterns` memory note
* spawn_subscriber() creates a Client + thread iterating Connection;
drains incoming Publish into an mpsc channel and emits a oneshot on
SubAck arrival
* collect_messages(rx, expected_count, timeout) — bounded recv loop
that respects a wall-clock deadline (no `loop { iter.recv() }`)
* Two named tests:
live_broker_anonymous_event_roundtrips_all_six_topics
Subscribe to ruview/<node>/bfld/+/state with the wildcard, await
SubAck, publish an Anonymous event with zone, collect 6 messages,
assert every expected entity name appears exactly once.
live_broker_restricted_event_omits_identity_risk
Same setup, publish a Restricted event, collect up to 6 (will
only see 5), assert identity_risk is absent.
Test discipline (per the workspace memory):
- per-test unique client_id (prevents broker session collisions)
- subscriber eventloop pumped until SubAck BEFORE publishing
- explicit timeout instead of infinite recv (no test hangs on misconfig)
- publisher Connection drained in its own thread (rumqttc requirement)
- 200ms sleep between publisher construction and first publish to let
CONNECT complete (otherwise messages are queued before the session
is open, and mosquitto silently drops them in some configurations)
When BFLD_MQTT_BROKER is unset:
- broker_env() returns None
- Test prints a one-line skip message to stderr and returns Ok(())
- Both tests show as passing in cargo output
ACs progressed:
- ADR-122 AC1 end-to-end demonstrable — when a broker is available,
the test proves a BfldEvent traverses RumqttPublisher, the network,
and an MQTT subscriber, arriving with the correct topic shape and
payload encoding.
- ADR-122 AC4 enforced over the wire — the Restricted-class test
proves identity_risk does not even reach the broker, not just that
it's stripped at render_events.
Test config:
- cargo test --no-default-features → 72 passed
- cargo test → 169 passed
- cargo test --features mqtt → 178 passed (176 + 2 skip-mode tests)
Out of scope (next iter target):
- BfldPipelineHandle: Arc<Mutex<BfldPipeline>> + a worker thread that
pumps inbound (SensingInputs, IdentityEmbedding) channel into MQTT.
Single-call "set up publisher and walk away" API for operators.
- CI workflow that starts mosquitto in a Docker service container and
sets BFLD_MQTT_BROKER so the integration test actually runs.

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::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

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)

Iter 22. Abstracts the MQTT publish boundary without pulling in tokio or
rumqttc yet. The trait is sync (callers can hold &mut self without an
async runtime); the production rumqttc-backed impl in iter 23 will drive
a tokio task internally and present the same sync surface here.
Added (in src/mqtt_topics.rs, gated on `feature = "std"`):
- Publish trait with associated Error type
- CapturePublisher (Vec-backed; default-constructible) for unit tests
- publish_event<P: Publish>(publisher, event) -> Result<usize, P::Error>
Iterates render_events(event) and forwards each TopicMessage to
publisher.publish(). Returns the count actually published, or the
publisher's error short-circuited on first failure.
- pub use Publish, CapturePublisher, publish_event from lib.rs
tests/mqtt_publish_loop.rs (7 named tests, all green):
capture_publisher_records_every_message

error AND leaves the first two messages durably published)
capture_publisher_error_type_is_infallible
(compile-time witness that CapturePublisher cannot panic the loop)
ACs progressed:
- ADR-122 §2.2 publisher boundary — the broker-facing surface is now a
named trait operators can mock, swap, or wrap with retries.
- ADR-122 AC4 — publish_event respects the iter-21 class gating; Raw /
Derived events produce zero broker traffic by definition.
- ADR-118 invariant I1 — even if the broker connection somehow regressed,
the trait-level publish_event cannot exfiltrate a Raw frame because
render_events returns empty first.
Test config:
- cargo test --no-default-features → 72 passed (mqtt_publish_loop cfg-out)
- cargo test → 169 passed (162 + 7)
Out of scope (next iter target):

Iter 21. Lands ADR-122 §2.2 topic shape + class-gated routing as a pure
function. No broker dep yet — that lands in iter 22 with tokio + rumqttc
behind an `mqtt` feature. This iter is the routing policy, separated for
testability.
Added (gated on `feature = "std"`):
- src/mqtt_topics.rs:
* TopicMessage { topic: String, payload: String }
* TopicMessage::ruview_topic(node, entity) builds the canonical
`ruview/<node>/bfld/<entity>/state` shape
* render_events(&BfldEvent) -> Vec<TopicMessage>:
class < Anonymous (0/1): returns empty (raw/derived are local only)
class >= Anonymous (2/3): emits presence + motion + person_count +
confidence, plus zone_activity if zone_id set
class == Anonymous (2) ONLY: also emits identity_risk
class == Restricted (3): identity_risk is suppressed even with score
- pub use render_events, TopicMessage from lib.rs
Payload encoding:
- presence: "true" | "false"
- motion: "{:.6}" — fixed-precision decimal in [0.0, 1.0]

ACs progressed:
- ADR-122 §2.2 topic shape now matches the documented format byte-for-byte.
- ADR-122 AC4 — per-class topic gating: classes 2 / 3 publish disjoint
sets, with identity_risk uniquely guarded.
- ADR-118 invariant I1 reaching the public surface — Raw frames produce
zero topic messages, so even a buggy publisher loop cannot leak them.

Iter 20. Adds the wire-bytes companion to BfldPipeline::process so
callers needing BfldFrame (for ESP-NOW, UDP, file dump, witness
bundles, etc.) don't have to drop down to BfldEmitter + manual
BfldFrame construction.
Added (in src/pipeline.rs):
- BfldPipeline::process_to_frame(
inputs: SensingInputs,
header_template: BfldFrameHeader,
payload: BfldPayload,
embedding: Option<IdentityEmbedding>,
) -> Option<BfldFrame>
Algorithm:
1. Cache timestamp_ns from inputs (consumed by the inner process()).
2. Call self.process(inputs, embedding) — gate logic decides drop/emit.
Returns None if the gate rejects, propagating to caller.
3. Clone header_template, override timestamp_ns and privacy_class from
the current pipeline state (privacy_mode-aware).
4. Build via BfldFrame::from_payload — CRC covers the section-prefixed
payload bytes per ADR-119 §2.2.
Separation of concerns: pipeline owns gate / ring / hasher state; caller
owns AP / STA / session identity (provided via header_template).
tests/pipeline_to_frame.rs (6 named tests, all green):
process_to_frame_emits_frame_under_low_risk
(timestamp_ns + privacy_class correctly propagated from pipeline)
process_to_frame_returns_none_under_sustained_high_risk
(gate Reject path: two consecutive high-risk calls → None)
process_to_frame_round_trips_through_bytes
(frame.to_bytes() → BfldFrame::from_bytes() → parse_payload() identity)
process_to_frame_overrides_class_in_privacy_mode
(enable_privacy_mode → frame.header.privacy_class = Restricted byte)
process_to_frame_preserves_header_template_identity_fields
(ap_hash, sta_hash, session_id, channel from template survive)
process_to_frame_uses_input_timestamp_not_template_timestamp
(template.timestamp_ns = 12345 is overridden by inputs.timestamp_ns)
ACs progressed:
- ADR-118 §2.1 wire-bytes consumer path now reachable from BfldPipeline,
not just from low-level BfldEmitter + manual frame construction.
- ADR-119 AC5/AC6 — round-trip-through-bytes test exercises the full
pipeline+frame stack, not just the frame in isolation.
- ADR-122 §2.2 prep — the BfldFrame is the wire format MQTT eventually
publishes via tokio loop (next iter pair); process_to_frame is the
per-frame producer that loop will call.
Test config:
- cargo test --no-default-features → 72 passed (pipeline_to_frame cfg-out)
- cargo test → 152 passed (146 + 6)
Out of scope (next iter target):
- BfldPipelineHandle: Arc<Mutex<BfldPipeline>> + tokio task that pumps
an inbound (SensingInputs, IdentityEmbedding) channel into MQTT
per-class topics (ADR-122 §2.2). Brings in tokio + rumqttc deps
behind a `mqtt` feature.
- Cargo benchmark: pipeline throughput target ≥ 40 frames/sec on a
Pi 5 core (ADR-118 §6 P2 effort estimate).

Iter 19. Public lib.rs entry point per ADR-118 §2.1. Thin facade over
BfldEmitter that adds a config-driven builder and a privacy_mode
toggle for emergency demote-to-Restricted without rebuilding the
gate/ring/hasher state.
Added (gated on `feature = "std"`):
- src/pipeline.rs:
* BfldConfig { node_id, default_zone_id, privacy_class, signature_hasher }
with new/with_zone/with_privacy_class/with_signature_hasher builder
* BfldPipeline { baseline_class, privacy_mode, emitter }
* BfldPipeline::new(config) — initializes the underlying emitter
* process(inputs, embedding) -> Option<BfldEvent>
Delegates to emitter.emit() then post-processes: if privacy_mode is
engaged, demotes the resulting event to Restricted and calls
apply_privacy_gating to strip identity fields
* enable_privacy_mode() / disable_privacy_mode() / is_privacy_mode_enabled()
* current_privacy_class() — returns Restricted when privacy_mode else baseline
* current_gate_action() — delegate diagnostic
- pub use BfldConfig, BfldPipeline from lib.rs
Design note: the privacy_mode override is applied post-emission, NOT by
rebuilding the emitter. This preserves gate state (current action,
pending transitions), ring contents, and hasher salt across the toggle —
critical for incident response where the operator needs to keep
detecting anomalies while temporarily redacting the public surface.

ACs progressed:
- ADR-118 §2.1 — public entry point now matches the implementation
plan §1.2 sketch: BfldPipeline::new(config) → process() → BfldEvent.
Future iters add process_to_frame() and the tokio MQTT loop.
- ADR-118 §1.5 enable_privacy_mode requirement — operator can engage
Restricted-class redaction without restarting the pipeline or
losing in-flight detection state. First runtime witness of this.

- cargo test --no-default-features → 72 passed (pipeline cfg-out)
- cargo test → 146 passed (137 + 9)
Out of scope (next iter target):

for callers that need wire-format bytes rather than JSON events.
- BfldPipelineHandle wrapping the pipeline in Arc<Mutex<...>> + a
tokio task that pumps an MQTT loop (ADR-122 §2.2 emitter half).

Iter 18. Consolidates the embedding-vs-risk-factor hashing-input
selection behind a single typed API. Replaces the two ad-hoc paths
that lived in emitter.rs through iter 17:
* inline `emb.as_slice().iter().flat_map(|f| f.to_le_bytes())`
* private `canonical_risk_bytes(&inputs) -> [u8; 16]`
Added (gated on `feature = "std"`):
- src/identity_features.rs:
* IdentityFeatures<'a> enum: Embedding(&'a IdentityEmbedding) |
RiskFactors { sep, stab, consist, conf }
* from_embedding / from_risk_factors const constructors
* canonical_byte_len() const fn — no allocation, predicts wire length
* write_canonical_bytes(&mut Vec<u8>) — reusable-buffer path
* canonical_bytes() -> Vec<u8> — allocating convenience
* compute_hash(&SignatureHasher, day_epoch) -> [u8; 32]
* RISK_FACTOR_BYTES const (= 16)
- pub use IdentityFeatures, RISK_FACTOR_BYTES from lib.rs
Refactor:

let features = match &embedding {
Some(emb) => IdentityFeatures::from_embedding(emb),
None => IdentityFeatures::from_risk_factors(sep, stab, consist, conf),
};
features.compute_hash(h, day_epoch)

These two tests assert that the refactored encoder produces
bit-identical hashes to iter 16's inline path. Existing deployed
nodes upgrading to iter 18 see no rf_signature_hash flip.
ACs progressed:
- ADR-120 §2.3 — features canonical-bytes representation now has a
single source of truth in the codebase; future feature additions
pass through one named encoder rather than scattered byte-fiddling.
- ADR-118 invariant I2 — IdentityFeatures borrows &IdentityEmbedding,
it doesn't take ownership. The embedding's Drop / no-Serialize
guarantees continue to hold across the canonical-bytes path.
Test config:
- cargo test --no-default-features → 72 passed (identity_features cfg-out)
- cargo test → 137 passed (128 + 9)
Out of scope (next iter target):
- Wire IdentityFeatures into a public emitter input path so callers
can supply pre-constructed IdentityFeatures rather than the bare
embedding + risk factors. (Soft refactor; current API is sufficient.)
- BfldPipeline facade — single struct combining BfldEmitter +
BfldFrame producer + MQTT publisher (ADR-118 §2.1 lib.rs entry point).

Iter 17. Lands the BFLD JSON wire spec format for rf_signature_hash —
a "blake3:" prefix followed by 64 lowercase hex chars. Replaces the
default serde array-of-integers encoding which was unusable for
downstream consumers (HA, Matter, MQTT).
Added (in src/event.rs):
- ser_rf_signature_hash<S>(hash: &Option<[u8;32]>, s) custom serializer
- Field attribute on BfldEvent.rf_signature_hash now uses
serialize_with = "ser_rf_signature_hash" alongside skip_serializing_if
- nibble_to_hex(u8) -> char private const fn (no `hex` crate dep needed
for 32 bytes; lowercase hex is trivial)

end_to_end_restricted_class_omits_hash_even_with_hasher_set
(class 3: even with hasher installed, JSON omits the hash)
ACs progressed:
- BFLD wire spec §6 — rf_signature_hash JSON shape now matches the
documented format ("blake3:..."); HA / Matter consumers can parse
it without custom byte-array decoding.
- ADR-118 §1 invariant I3 — visibility: the JSON wire form now
cryptographically tags the hash with its algorithm prefix, so
consumers can verify they're not parsing a different (weaker)
hash that a future PR might accidentally substitute.
Test config:
- cargo test --no-default-features → 72 passed (json_hash_format cfg-out)
- cargo test → 128 passed (123 + 5)
Out of scope (next iter target):
- IdentityFeatures typed encoder so callers feeding BfldEmitter don't
need to know that embedding bytes serve as hasher input.
- Replace the manual hex push with `hex::encode` if/when the workspace
takes on the `hex` crate dep for other reasons; current path saves
the dep without sacrificing correctness.

Iter 16. End-to-end ADR-120 §2.3 wiring: BfldEmitter now produces
rf_signature_hash derived from (site_salt, day_epoch, features), with
the IdentityEmbedding bytes as the preferred feature source. Closes
the gap from iter 15 — the hasher is now reachable from the pipeline.
Added (in src/emitter.rs):
- BfldEmitter.signature_hasher: Option<SignatureHasher> field
- BfldEmitter::with_signature_hasher(SignatureHasher) -> Self builder
- emit_with_oracle computes derived_hash BEFORE pushing embedding to ring:
1. unix_secs = inputs.timestamp_ns / NS_PER_SEC
2. feature bytes: embedding.as_slice() flattened to LE f32 bytes,
OR fallback canonical_risk_bytes(&inputs) (4-tuple of LE f32)
3. hasher.compute_at(unix_secs, &bytes)
- Derived hash overrides inputs.rf_signature_hash; when hasher absent
caller-supplied value passes through unchanged (backward compat)
- canonical_risk_bytes(&inputs) -> [u8; 16] private helper for fallback

ACs progressed:
- ADR-120 §2.7 AC2 — cross-site isolation now provable at the public
emitter surface, not just inside the hasher module.
- ADR-118 §2.1 pipeline integration — derived rf_signature_hash flows
through to the BfldEvent without caller participation. Operators
install the hasher once at boot; per-frame code never sees site_salt.
Test config:
- cargo test --no-default-features → 72 passed (emitter_hasher cfg-out)
- cargo test → 123 passed (117 + 6)
Out of scope (next iter target):

derived hash, parsed back, hash field present and base64-encoded
(or hex-encoded) per the JSON wire spec.

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

*** 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 14. Wires every iter-1..13 primitive into a single ADR-118 §2.1
pipeline: per-frame sensing inputs go in, a privacy-gated BfldEvent
(or None) comes out. First time every constituent is exercised together.
Added (gated on `feature = "std"`):
- src/emitter.rs:
* SensingInputs struct — 11 fields: timestamp_ns, presence, motion,
person_count, sensing_confidence, sep, stab, consist, risk_conf,
rf_signature_hash (Option)
* BfldEmitter struct owning: node_id, default_zone_id, privacy_class,
CoherenceGate, EmbeddingRing
* Builder API: new(node_id) → with_zone(...) → with_privacy_class(...)
* current_action() / ring_len() diagnostic accessors
* emit(inputs, embedding) → Option<BfldEvent>

ring_unchanged_when_no_embedding_supplied
ACs progressed:
- ADR-118 AC1 (BFLD core pipeline integration) — every component from
iter 1 (frame format) through iter 13 (event) is now traversed by a
single emit() call. This is the first end-to-end smoke proof.
- ADR-121 AC4 — Recalibrate-grade sustained score triggers ring drain
(verified by ring_len() going from 5 to 0).
- ADR-122 AC1 — privacy_class threaded through the pipeline so the
output event is correctly gated for HA/Matter consumption.
Test config:
- cargo test --no-default-features → 64 passed (emitter cfg-out)
- cargo test → 109 passed (102 + 7)
Out of scope (next iter target):
- Wiring rf_signature_hash computation from BLAKE3-keyed(site_salt,
features) per ADR-120 §2.3 — the SensingInputs.rf_signature_hash
is supplied by caller for now; needs a SignatureHasher with site_salt
initialization in a follow-up iter.
- Embedding ring → identity_separability_score derivation (currently
`sep` is caller-supplied; should be computed from ring contents).
- MQTT topic publisher wrapping BfldEmitter (ADR-122 §2.2) — depends
on a runtime (tokio).

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

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.

Iter 12. Wires the ADR-121 §2.6 Recalibrate exemption: when an enrolled
person_id matches the current high-separability cluster, the gate
downgrades the would-be Recalibrate to PredictOnly. The high score is
the *intended* outcome of a Soul Signature match, not an attacker-grade
sniffer arrival — so site_salt rotation is suppressed.
Added (no_std-compatible):
- src/coherence_gate.rs additions:
* MatchOutcome enum: Match { person_id: u64 } | NotEnrolled | Suppressed
* SoulMatchOracle trait with matches_enrolled() -> MatchOutcome
* NullOracle (default-constructible, always reports NotEnrolled)
* CoherenceGate::evaluate_with_oracle(score, ts, &O: SoulMatchOracle)
— same hysteresis/debounce as evaluate(), but downgrades Recalibrate
to PredictOnly when oracle returns Match { .. }
* Refactored evaluate(): extracted advance_state(target, ts) shared with
evaluate_with_oracle. evaluate is now a 4-line wrapper.
- pub use MatchOutcome, NullOracle, SoulMatchOracle from lib.rs

crate (TBD) to plug in a real RaBitQ-backed oracle.
- ADR-118 §1.4 Soul Signature companion contract is now structurally
enforced at the gate boundary: enrolled subjects do not trigger
site_salt rotation; everyone else does.

person_count sensing fields.
- Optional: connect SoulMatchOracle into the actual `--features
soul-signature` build (compile-time gate around a re-export).

Iter 11. Wraps the stateless GateAction classifier from iter 10 with two
stabilizing mechanisms per ADR-121 §2.5:
* ±0.05 HYSTERESIS — a score must clear the current band's edge by
HYSTERESIS before the gate considers the next band.
* 5-second DEBOUNCE_NS — a different action must persist that long
before it becomes current; returning to the current band cancels it.
Added (no_std-compatible):
- src/coherence_gate.rs:
* HYSTERESIS const (0.05) + DEBOUNCE_NS const (5_000_000_000)
* CoherenceGate { current, pending: Option<(GateAction, u64)> }
* new() / Default / current() / pending() (diagnostic accessors)
* evaluate(score, timestamp_ns) -> GateAction
Algorithm: compute effective_target via per-direction hysteresis check,
promote pending after DEBOUNCE_NS elapsed, cancel pending on return to
current band, reset debounce clock if pending target changes
* Private helpers effective_target / action_idx / upper_edge_of / lower_edge_of

± 0.05 of a threshold within a 5-second window.

Iter 9. Lands ADR-120 §2.4 — the only operation that can lower a frame's
information content. Demote is monotonic by construction (Result::Err
on non-monotone target), strips payload sections per the target class
table, and re-syncs header.privacy_class + CRC32.
Added:
- src/privacy_gate.rs (gated on `feature = "std"`):
* PrivacyGate unit struct (+ Default impl)
* PrivacyGate::demote(BfldFrame, target: PrivacyClass) -> Result<BfldFrame>
* Stripping policy:
target >= Anonymous (2): zeros + clears compressed_angle_matrix and
csi_delta; sets csi_delta = None so from_payload clears HAS_CSI_DELTA
target >= Restricted (3): also zeros + clears amplitude_proxy and phase_proxy
* zeroize_then_clear helper — overwrite with 0 then black_box then truncate
- BfldError::InvalidDemote { from: u8, to: u8 } variant
- pub use PrivacyGate from lib.rs
Note: demote does NOT zero the original Vec capacity that the heap allocator
may still hold — the buffers we own are zeroed and cleared, but the
intermediate Vec passed back to BfldFrame::from_payload reallocates anew.
For strict heap zeroization in regulated deployments, a follow-up iter can
substitute zeroize::Zeroizing<Vec<u8>>.

ACs progressed:
- AC5 ↑ — privacy_mode enforcement at the frame-class boundary now works
through PrivacyGate, not just the BfldEvent emitter (deferred). When the
active class is Anonymous (2) or Restricted (3), the angle matrix /
csi_delta / amplitude / phase sections that carry identity information
are zeroed before any downstream code sees them.
- AC4 ↑ — demoted frames retain valid CRC; the round-trip-through-bytes
test proves bit-correctness after the class transition.

- cargo test --no-default-features → 31 passed (privacy_gate cfg-out)
- cargo test → 60 passed (53 + 7)
Out of scope (next iter target):

Iter 8. Lands the lifecycle half of ADR-120 §2.5: a bounded, in-place,
no_std-compatible ring of IdentityEmbeddings. Insertion is O(1); when
full, push evicts the oldest entry, whose Drop runs and zeroizes the
f32 storage. drain() clears the ring on the coherence-gate Recalibrate
action (ADR-121 §2.4).
Added:
- src/embedding_ring.rs (no_std-compatible; no heap):
* EmbeddingRing struct with [Option<IdentityEmbedding>; RING_CAPACITY=64]
backing array, head cursor, count
* EmbeddingRing::new() / Default impl
* push(emb) -> Option<IdentityEmbedding> (evicted oldest when full)
* len / is_empty / capacity / is_full / iter
* iter() returns occupied slots in insertion order (oldest first)
* drain() -> usize (empties the ring, returns count drained)

which the iter-7 Drop impl zeroizes. The "in-RAM-only" lifecycle is now
end-to-end: bounded buffer in, FIFO out, drain on Recalibrate.

- cargo test --no-default-features → 31 passed (22 + 9)
- cargo test → 53 passed (44 + 9)
Out of scope (next iter target):

Iter 7. First structural enforcement of ADR-118 invariant I2 — the
identity embedding is in-RAM-only and cannot be serialized, cloned,
or copied. Lands the type itself; ring-buffer lifecycle is next.
Added:
- src/embedding.rs (no_std-compatible; lives in the lib regardless of features):
* IdentityEmbedding wrapping [f32; EMBEDDING_DIM=128]
* from_raw(values), as_slice() -> &[f32], l2_norm(), len(), is_empty()
* NO Serialize, NO Clone, NO Copy impl
* Custom Debug emits only dim + L2 norm + "<redacted>" — never raw values
* Drop overwrites storage with 0.0 then core::hint::black_box(...) to defeat
dead-store elimination (DSE would otherwise let the compiler skip the write)
- Compile-time structural guards via static_assertions:
assert_impl_all!(IdentityEmbedding: Drop)
assert_not_impl_any!(IdentityEmbedding: Copy, Clone)

drop_overwrites_storage_with_zeros
(Drop runs without panic; bit-level zeroization is asserted by the
black_box-guarded loop. Unsafe peek-after-free is intentionally avoided.)
ACs progressed:
- AC5 ↑ — even in `privacy_mode`, the IdentityEmbedding type can't be reached
from any serialization path because the type system rejects the impl.
- I2 ↑ — Drop, no Clone, no Copy, redacted Debug are all in place as
compile-time guarantees.

Iter 6. Connects the typed payload parser (iter 5) to the framed
wire format (iter 4): the CRC32 now covers the section-prefixed
payload bytes per ADR-119 §2.2 ("CRC32 covers all section bytes
including length prefixes").
Added:
- BfldFrame::from_payload(header, &BfldPayload) -> Self
Auto-syncs header.flags HAS_CSI_DELTA bit from payload.csi_delta.is_some(),
serializes payload via to_bytes(), feeds BfldFrame::new() which computes
payload_len + payload_crc32 over the section-prefixed bytes.
- BfldFrame::parse_payload(&self) -> Result<BfldPayload, BfldError>
Reads HAS_CSI_DELTA bit from header.flags and dispatches to

ACs progressed:
- AC5 ↑ — full payload round-trip through the framed bytes (closes
the round-trip leg from BfldPayload through wire and back).
- AC6 ↑ — same input produces same bytes through both layers.
- AC4 ↑ — CRC mismatch on tampered section bodies and tampered section
length prefixes both surface as BfldError::Crc, not as silent acceptance
or as a deeper parser error.
Test config:
- cargo test --no-default-features → 17 passed (integration tests cfg-out)
- cargo test → 39 passed (3 + 6 + 7 + 8 + 8 + 7)
Out of scope (next iter target):
- PrivacyGate::demote(frame, target_class) — ADR-120 §2.4 class transition
transformer with subtle::Zeroize on dropped fields.
- IdentityEmbedding newtype with no Serialize impl (ADR-120 §2.5 / I2).

Iter 2 of the BFLD rollout. Adds the canonical little-endian wire form for
BfldFrameHeader with safe (no unsafe) encoders/decoders. Covers ADR-119 AC5
(round-trip preservation), AC6 (deterministic serialization), and partial
AC1 (constant wire size) / AC4 (rejects bad magic + bad version).
Added:
- BfldFrameHeader::empty() — convenience constructor with magic/version set
- BfldFrameHeader::to_le_bytes() -> [u8; 86]
- BfldFrameHeader::from_le_bytes(&[u8; 86]) -> Result<Self, BfldError>
- Field-level doc strings on every header field (clears all 21 missing-docs
warnings the iter 1 commit logged)
- tests/header_roundtrip.rs — 6 named tests:
header_roundtrip_preserves_all_fields
header_serialization_is_deterministic
header_magic_is_at_offset_zero_little_endian (LE byte order proof)
parsing_rejects_invalid_magic
parsing_rejects_unsupported_version
wire_size_is_constant
Implementation notes:
- Used #[derive(Default)] on BfldFrameHeader so empty() can build cleanly.
- to_le_bytes copies packed fields into locals first to dodge unaligned-
borrow lints; from_le_bytes uses try_into() on byte slices.
- All field reads/writes are #[forbid(unsafe_code)] compliant.
Out of scope (next iter targets):
- BfldFrame (header + payload sections + section-length prefixes + CRC32
computation over payload bytes only) — needs the `crc` crate dependency.
- PrivacyGate::demote(...) skeleton (ADR-120 §2.4).
- SinkMarker traits (LocalSink / NetworkSink / MatterSink) — ADR-120 §2.2.
cargo test -p wifi-densepose-bfld --no-default-features → 9 passed, 0 failed

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

Two closing P8 deliverables that complete the local-side publishing
scaffolding. The remaining work is all credential-bearing user
action.
1. `cog/app-registry-entry.json` — the exact JSON payload to paste
into cognitum-one's `app-registry.json`. Schema discovered by
fetching the live registry (105 cogs, 11 categories) and
matching the existing `ruview-densepose` entry verbatim. Keys:
id, name, category, version, size_kb, difficulty, description,
featured, config[], sha256, binary_size
cog-ha-matter slots in under `category: "building"` (smart home
/ building automation — the natural HA / Matter category, vs
`network` which is more about transport bridges).
7 config[] entries mirror our CLI surface:
sensing_url, mqtt_host, mqtt_port, privacy_mode,
mdns_hostname, mdns_ipv4, no_mdns
Two post-build fields left as `<FILL_IN_...>` markers:
sha256 (paste from the workflow artifact's .sha256)
binary_size (wc -c < the binary)
Schema validated: all 10 required keys present, parses as JSON.
2. `cog/RELEASE-CHECKLIST.md` — one-page mechanical playbook with
four explicit "🔑 USER ACTION" gates. Each gate names exactly
what the user (or org admin) has to do that the pipeline cannot:
a) provision GCP_CREDENTIALS + HAS_GCP_CREDENTIALS org var
b) provision COGNITUM_OWNER_SIGNING_KEY GH secret
c) gcloud auth login (only if uploading locally)
d) PR app-registry.json into cognitum-one
Plus pre-release test gate, tag-push command, post-release
verification curl, and a rollback procedure using GCS object
versioning (per ADR-100 §"GCS misconfiguration risks").
Stop-condition check (cron's predicate: "ALL local-side publishing
scaffolding is complete and the only remaining work requires user
action"):
✅ cog/manifest.template.json
✅ cog/Makefile (build / sign / upload / verify / clean)
✅ cog/README.md
✅ cog/app-registry-entry.json (this commit)
✅ cog/RELEASE-CHECKLIST.md (this commit)
✅ .github/workflows/cog-ha-matter-release.yml (3 jobs, gated)
✅ dist/ handling (gitignored, created by make)
🔑 4 user-action gates explicitly enumerated in the checklist
The cron should STOP after this iter — the local-side scaffolding
is complete and the remaining work is the four named credential
gates that the pipeline cannot self-serve.

New `.github/workflows/cog-ha-matter-release.yml`:
* Triggers on `cog-ha-matter-v*` tag-push + manual dispatch
* Three jobs: build-x86_64, build-arm, publish-gcs
* x86_64: native ubuntu-latest cargo build
* arm: aarch64-unknown-linux-gnu via apt-installed gcc-aarch64-linux-gnu
linker (no `cross` dep needed — keeps workflow self-contained)
* Each build job runs make build-{arch} + make sign-{arch} +
gated Ed25519 sign step (skipped when COGNITUM_OWNER_SIGNING_KEY
secret is unset — workflow still produces unsigned artifacts so
we get build coverage now and signing later without re-merging)
* publish-gcs job gated on `vars.HAS_GCP_CREDENTIALS == 'true'`
so the workflow is safe to merge before credentials land —
no-op until the org admin sets the variable
* Uploads binary + sha256 + (optional) sig to
`gs://cognitum-apps/cogs/{arch}/cog-ha-matter-{arch}`
* Prints the app-registry.json snippet for the cognitum-one PR
(so the publish step's output is the exact JSON the user pastes)
Fixed a bug inherited from cog-pose-estimation's Makefile: the
precedent produces `dist/cog-cog-pose-estimation-arm` (double
`cog-` prefix because CRATE name already starts with `cog-`) but
the manifest URL has single prefix `cog-pose-estimation-arm`. The
upload path doesn't match the binary_url — a latent bug in the
pose cog's pipeline.
My copy now produces `dist/cog-ha-matter-arm` matching the
manifest URL `cog-ha-matter-{{ARCH}}`. Changed: Makefile (build /
sign / upload / verify / clean targets), workflow (artifact names
+ gsutil paths), README (local dry-run instructions). The
cog-pose-estimation precedent is unchanged — separate fix if/when
the user wants to align it.
What this iter does NOT do (P8 remaining):
* provision GCP_CREDENTIALS / COGNITUM_OWNER_SIGNING_KEY secrets
(user action — needs org admin access)
* actually run the workflow (needs a `cog-ha-matter-v0.1.0` tag
push, or workflow_dispatch from the Actions tab)
* append to app-registry.json in cognitum-one (separate repo PR)
Next iter: tag a v0.0.1-dev (so the workflow runs once + we see
any build-time errors on real CI runners) OR scaffold the
app-registry.json patch payload as a check-in doc.

Mirrors v2/crates/cog-pose-estimation/cog/ so the Seed runtime
treats cog-ha-matter identically — `cognitum cog install ha-matter`
behaves like `cognitum cog install pose-estimation`.
Files:
* cog/manifest.template.json — 9-field manifest with {{VERSION}}
+ {{ARCH}} slots, hand-edited by the Makefile signer
* cog/Makefile — same target set as cog-pose-estimation:
build / build-arm / build-x86_64
sign / sign-arm / sign-x86_64 (Ed25519 step is TODO,
blocked on COGNITUM_OWNER_SIGNING_KEY provisioning —
same blocker as cog-pose-estimation)
upload / upload-arm / upload-x86_64
manifest (delegates to `cargo run -- --print-manifest`)
release (= build + sign + upload + manifest)
verify (sha256sum vs sidecar)
clean
Adds `mkdir -p dist` to build steps so the gitignored dist/
folder is created on first build.
* cog/README.md — what this cog does, layout map, local dry-run
instructions, gcloud auth requirements, the JSON snippet to
paste into app-registry.json (in the separate cognitum-one
repo, not this one)
Local dist/ is intentionally not committed: top-level .gitignore
matches `dist/` globally, the Makefile creates it on demand.
What this commit does NOT do (P8 remaining):
* cross-compile build (needs `rustup target add
aarch64-unknown-linux-gnu x86_64-unknown-linux-gnu` + linker)
* sign the binaries (COGNITUM_OWNER_SIGNING_KEY not provisioned)
* gsutil cp to gs://cognitum-apps/ (needs user's gcloud auth)
* append to app-registry.json (lives in cognitum-one repo —
separate PR there)
Next iter: a CI workflow that runs `make build sign verify` on
tag-push, so the local-side pipeline is fully exercised even
without the production credentials.

Two landings that flip P4 to shipped:
1. main.rs now actually registers the mDNS responder. New CLI:
--mdns-hostname (default: cog-ha-matter.local.)
--mdns-ipv4 (default: 127.0.0.1)
--no-mdns (skip for restrictive CI / multi-instance)
Responder boots after the publisher; failure logs WARN + falls
back to manual HA config instead of killing the cog. The
handle's Drop sends the mDNS goodbye packet on shutdown so HA's
discovery sees a clean service-leave (no stale device card).
2. Embedded rumqttd broker DEFERRED to v0.7 per dossier §8 ranking.
The dossier's prioritised v1 scope is:
1. --privacy-mode audit-only
2. cog manifest + Ed25519 signing + store listing
3. local SONA fine-tuning loop
4. HACS gold-tier integration
5. Matter Bridge (v0.8)
Embedded broker is not in that list. Every HA install already
has mosquitto or HA Core's built-in broker — adding ~2 MB of
binary + ACL config surface for marginal benefit didn't earn a
v1 slot. Documented as row 6 of §4 v1 scope table with explicit
v0.7 target.
P4 row updated to ✅: mDNS half complete (record-builder +
ServiceInfo + live responder + main.rs wiring), witness half
complete (chain + JSONL + file + Ed25519), embedded broker
explicitly deferred with rationale citation to dossier §8.
Stop-condition check:
* dossier has "Recommended scope" section ✅ (§8, folded into
ADR §4)
* P2 (cog scaffold) ✅
* P3 (MQTT publisher wrap) ✅
* P4 (Seed-native enhancements) ✅
Cron's stop predicate evaluates: P2-P4 shipped AND dossier has
the recommended-scope section → STOP. The loop should TaskStop
itself after this iter unless the user wants P5 (RuVector
thresholds), P8 (cog signing), or P9 (HACS repo) to keep going.
64/64 tests green.
Co-Authored-By: claude-flow <ruv@ruv.net>
Closes the mDNS half of P4. `runtime::start_mdns_responder` binds
multicast via `mdns_sd::ServiceDaemon::new`, builds the
ServiceInfo from `MdnsService::to_service_info` (iter 9), and
registers — returning a typed handle that owns both daemon and
fullname.
Handle shape:
pub struct MdnsResponderHandle {
daemon: ServiceDaemon,
fullname: String,
}
impl MdnsResponderHandle {
pub fn fullname(&self) -> &str;
pub fn shutdown(self) -> Result<(), mdns_sd::Error>;
}
impl Drop for MdnsResponderHandle { /* best-effort */ }
Why explicit `shutdown` + best-effort `Drop`: a clean shutdown
sends a goodbye packet so HA's discovery integration sees the
service leave (good UX — no stale device card). `Drop` is the
fallback for panics / process termination but swallows errors
since panicking-in-Drop would mask the real failure.
1 new live-I/O test:
* mdns_responder_fullname_concatenates_instance_and_service_type
— actually binds multicast on the loopback adapter, registers,
asserts the fullname contains `_ruview-ha._tcp`, then
shutdown()s. Confirmed working on Windows; CI environments
where multicast bind is filtered will hit the gracefully-
skipping early return rather than failing the suite.
64/64 cog tests green (63 → 64).
ADR-116 P4: mDNS half ✅ (record-builder + ServiceInfo + live
responder), witness half ✅ (chain + JSONL + file + Ed25519).
Last piece is the embedded rumqttd broker so external mosquitto
becomes optional.
Co-Authored-By: claude-flow <ruv@ruv.net>
Pure conversion from our wire-format `MdnsService` to the
`mdns_sd::ServiceInfo` shape the responder daemon consumes. No
socket binding, no daemon registration yet — that lands next iter
as a `runtime::spawn_mdns_responder(info)` JoinHandle returning
helper, same shape as `runtime::spawn_publisher`.
* `MdnsService::to_service_info(hostname, ipv4) ->
Result<ServiceInfo, mdns_sd::Error>`
* `mdns-sd = "0.11"` added — aligned with the workspace pin from
wifi-densepose-desktop so the lockfile doesn't fork dalek-like
surfaces.
3 new tests:
* to_service_info_carries_service_type_and_port — locks that
`_ruview-ha._tcp` (with or without mdns-sd's trailing-dot
normalisation) and the control port round-trip through the
conversion
* to_service_info_propagates_txt_records — every locked TXT
key from iter 4 (cog_id, mqtt_port, privacy, proto, node_id,
cog_version) reachable via `get_property_val_str` on the
converted ServiceInfo
* to_service_info_does_not_silently_drop_caller_hostname —
locks the caller-side responsibility for the .local. suffix.
mdns-sd 0.11 accepts bare hostnames (verified empirically by
initial test expecting it to reject — it didn't), so the
wrapper layer must do the trailing-dot dance. Documenting
that via a named test catches future bumps where the lib
starts mutating the value.
63/63 cog tests green (60 → 63).
ADR-116 P4 now ⁶⁄₇: ✅ mDNS record-builder, ✅ chain, ✅ JSONL, ✅
file persistence, ✅ Ed25519 signing, ✅ ServiceInfo conversion;
⏳ daemon register + embedded broker.

Closes the cryptographic-attestation gap in ADR-116 §2.2: every
witness event can now be signed by the Seed's Ed25519 key, with
verify available to any auditor holding the public key.
Module shape (`src/witness_signing.rs`, kept separate from
`witness::` so the hash chain stays usable without dalek linked
in — important for the wasm32 audit-verifier variant we'll ship
later):
* sign_event(event, &SigningKey) -> Signature
* verify_signature(event, &Signature, &VerifyingKey)
-> Result<(), SignatureVerifyError>
* signature_to_hex / signature_from_hex (128-char lowercase,
matches the witness hex convention)
* SignatureVerifyError::Invalid
* SignatureParseError::{Length, Hex}
Key design point: signature covers the SAME canonical bytes
witness::hash_event hashes. That means:
1. A signed event commits to the entire event content (kind,
payload, timestamp, seq, prev_hash) — no field can be
retroactively changed without invalidating both the hash AND
the signature.
2. The signature implicitly commits to the event's *chain
position* via prev_hash — splicing a signed event into a
different chain breaks verification.
Adds `ed25519-dalek = "2.1"` to cog-ha-matter (already in
workspace via ruv-neural, version kept aligned).
9 new tests:
* sign_and_verify_round_trip
* verify_rejects_signature_under_wrong_key
* verify_rejects_tampered_event (mutate payload after sign)
* verify_rejects_event_with_wrong_prev_hash (splice attack)
* signature_hex_round_trip
* signature_from_hex_rejects_wrong_length
* signature_from_hex_rejects_non_hex
* signature_is_deterministic_for_same_event_and_key
(locks Ed25519's determinism — catches future accidental
swap to a randomized scheme)
* different_events_produce_different_signatures
60/60 cog tests green (51 → 60). Key management is intentionally
out of scope here — the cog runtime reads the Seed's key from the
Cognitum control plane's secure store (separate concern).
ADR-116 P4 now ⁵⁄₆: ✅ mDNS record, ✅ chain, ✅ JSONL, ✅ file
persistence, ✅ Ed25519 signing; ⏳ responder + embedded broker.
Co-Authored-By: claude-flow <ruv@ruv.net>
Closes the witness audit-bundle surface. The hash-chain primitive
+ JSONL serializer from earlier iters only handled one event at a
time; this lands the file-stream surface that operations actually
need:
* `WitnessChain::write_jsonl(&mut impl Write) -> io::Result<()>`
— streams every event as one line + `\n`, empty chain writes
zero bytes
* `WitnessChain::read_jsonl(impl BufRead) -> Result<WitnessChain,
WitnessReadError>` — parses event-by-event AND runs chain-level
`verify()` on the loaded chain, catching reordered or replayed
prefixes that per-event hashing alone misses
Critical security property: `read_jsonl` calls `WitnessChain::verify`
on the loaded chain BEFORE returning Ok. A forged bundle assembled
from two valid chains pasted together would slip past the
per-event hash check (each event's `this_hash` is internally
consistent) but the cross-event `prev_hash` linkage detects the
seam. Test `read_jsonl_chain_verify_catches_reordered_events`
locks this — swap two events in a 2-event bundle, see Verify error.
Error surface (new `WitnessReadError` enum):
* `Io { line_no, msg }` — read failure mid-stream
* `Parse { line_no, source }` — per-event from_jsonl_line failure
* `Verify { source }` — chain-level verify failure
`line_no` is 1-indexed so an auditor sees the same number their
text editor shows. Blank lines tolerated for hand-edited bundles.
7 new tests:
* empty chain writes zero bytes
* write→read round-trips a 3-event chain
* exactly N newlines for N events; trailing newline present
* blank lines / leading newline tolerated
* parse error surfaces with correct line_no
* reordered events caught by chain-level verify
* no-trailing-newline still loads the final event
51/51 cog tests green (44 → 51).

Third P4 sub-unit: serialize/parse for the witness hash chain so
audit bundles can be written to disk and replayed.
Wire shape (one record per line, alphabetical field order locked):
{"kind":"...","payload_hex":"...","prev_hash":"...","seq":N,
"this_hash":"...","timestamp_unix_s":N}
Why alphabetical field order: auditors archive whole bundles and
hash them. A rebuild that reordered fields would silently
invalidate every archival hash — locking the order is what makes
the JSONL stable across compiler / serde-json upgrades.
Why hex everywhere: human-greppable, monospace-friendly, no base64
ambiguity, no Vec<u8> JSON-array ugliness. Same convention as
ADR-101's `binary_sha256`.
Critically, `from_jsonl_line` RE-VERIFIES `this_hash` against
the canonical bytes derived from the parsed fields. A tampered
bundle fires `WitnessParseError::HashMismatch` BEFORE the event
loads — the parser is itself an auditor.
New surfaces:
* `WitnessHash::from_hex` (with structured length/parse errors)
* `WitnessEvent::to_jsonl_line`, `from_jsonl_line`
* `WitnessParseError` enum: Json | MissingField | WrongType |
HashLength | HashHex | PayloadHex | PayloadLength | HashMismatch
* private `hex_encode` / `hex_decode` helpers (no `hex` crate dep)
10 new tests:
* jsonl round-trip preserves all fields
* jsonl line has no embedded \n / \r (one record per line)
* jsonl field order is alphabetical (byte-stable archival)
* parser rejects tampered payload via HashMismatch
* parser rejects non-hex characters in hash
* parser rejects missing field
* hex encode/decode round-trip across empty / single byte / 0xff /
UTF-8 / arbitrary bytes
* hex decode rejects odd-length input
* WitnessHash::from_hex round-trip
* WitnessHash::from_hex rejects wrong length
44/44 cog tests green (34 → 44).
ADR-116 P4 row enumerates 4 sub-units now: ✅ mDNS record-builder,
✅ witness chain primitive, ✅ witness JSONL persistence,
⏳ responder + embedded broker + Ed25519 signing.
Co-Authored-By: claude-flow <ruv@ruv.net>
Second P4 unit: an append-only SHA-256 hash chain for tamper-evident
audit logging. ADR-116 §2.2 promised this for healthcare /
education / shared-housing deployments — this lands the primitive
with no key dependency so the next iter can layer Ed25519 signing
on top without touching the chain itself.
Module shape:
* `WitnessHash([u8; 32])` newtype + `WitnessHash::GENESIS` sentinel
* `WitnessEvent { seq, prev_hash, ts, kind, payload, this_hash }`
— once committed, every field is immutable
* `WitnessChain` — `append`, `tip`, `verify`, `events`
* `canonical_bytes` — length-prefixed serialization that prevents
the classic concatenation forgery
(`abc|def` ≠ `ab|cdef`)
* `WitnessVerifyError` — auditor-friendly error with `at: usize`
on every variant (SeqGap, PrevHashMismatch, HashMismatch)
13 new tests covering both happy path and active tampering:
* genesis hash all-zeros
* empty chain tip is genesis
* canonical bytes length-prefixed (anti-forgery)
* canonical bytes start with prev_hash (wire-format lock)
* append links to prev_hash
* seq monotonic from 0
* verify passes on clean chain
* verify catches tampered payload (fires HashMismatch)
* verify catches broken prev_hash link
* verify catches seq gap
* hash hex is 64 lowercase chars
* first event prev_hash == GENESIS (auditor anchor)
* different payloads → different hashes
Hash-chain over Merkle is the right tradeoff for the cog's event
rate (a few/min steady, dozens during a fall) — linear scan is
fine and we save the Merkle complexity for a future tier when
chains span days.
34/34 cog tests green (21 → 34).
ADR-116 P4 row updated to enumerate the three P4 sub-units shipped /
pending: (a) mDNS record-builder ✅, (b) witness hash-chain ✅, (c)

Opens P4 with the smallest extractable unit: a pure builder that
produces the wire-format `MdnsService` the responder will publish
next iter. Splitting the record-builder from the responder lets
us:
* lock the TXT-record surface with named unit tests so drift
between the cog and the HA-side YAML auto-discovery binding
fires a test instead of silently breaking deployments,
* swap the responder library (mdns-sd / zeroconf / pnet) without
touching content,
* include the advertisement in `--print-manifest` for Seed
integration tests that can't boot tokio.
TXT surface (sorted, RFC 6763):
| cog_id | "ha-matter" |
| cog_version | CARGO_PKG_VERSION |
| node_id | identity.node_id |
| mqtt_port | u16 stringified |
| privacy | "1" | "0" |
| proto | "ruview-ha/1" |
9 new tests:
* service_type locked to `_ruview-ha._tcp`
* instance_name carries node_id
* control_port advertises the *control plane*, not MQTT
* privacy flag is "1"/"0" (HA config flow reads it byte-stable)
* proto version locked to ruview-ha/1 (bump is deliberate)
* cog_id in TXT matches crate constant
* txt_records sorted for byte-stable mDNS responses
* **PII leak guard**: TXT must NOT carry hr_bpm, br_bpm, pose_*,
keypoint, ssid, lat, lon, mac, rssi — broadcasts in cleartext
so a future "let's add hr_bpm for convenience" patch fires
here, not in a privacy incident.
* required-keys lock — adding is fine, removing/renaming breaks
every deployed Seed.
21/21 cog tests green (12 → 21).

P3 closes the publisher wiring loop. `main.rs` now:
1. builds `PublisherInputs` from CLI args via the pure helper
extracted last iter,
2. opens a `broadcast::channel::<VitalsSnapshot>(256)`,
3. calls `runtime::spawn_publisher(inputs, rx)` — a thin
wrapper around ADR-115's `publisher::spawn` that owns the
`Arc<MqttConfig>` wrap,
4. holds the tx side so the channel stays open until P3.5
wires the sensing-server bridge,
5. awaits Ctrl-C or unexpected publisher exit (logged at WARN).
Two new tests:
* `spawn_publisher_returns_live_handle_without_broker` — proves
the wiring compiles and the rumqttc event loop survives an
unreachable broker (it retries internally; we abort the handle
inside 100 ms). Catches breakage from a future refactor that
accidentally pre-validates host reachability.
* `default_state_channel_capacity_is_reasonable` — locks the
`DEFAULT_STATE_CHANNEL_CAPACITY = 256` default; a regression to
e.g. 1 would surface here instead of as a dropped frame in
production under bursty multi-Seed federation.
12/12 cog-ha-matter tests green (10 → 12).
ADR-116 phase table: P3 flipped from "in progress" to ✅ wiring done,
with the P3.5 follow-up (sensing-server `/v1/snapshot` WS bridge)
explicitly named.
Co-Authored-By: claude-flow <ruv@ruv.net>
Adds `runtime::build_publisher_inputs(host, port, privacy, identity)` —
the side-effect-free helper that turns the cog's CLI surface into the
`(MqttConfig, OwnedDiscoveryBuilder)` pair ADR-115's `publisher::spawn`
consumes. Keeps the tokio runtime wiring out of the pure unit so the
mDNS responder + Seed control plane (P4) can build the same inputs
from different sources without going through clap.
8 new tests lock the wire-format invariants:
* host/port round-trip into MqttConfig
* privacy_mode propagation (P1 dossier item 7, FDA Jan 2026)
* discovery_prefix defaults to "homeassistant"
* discovery carries node_id + sw_version + friendly_name
* via_device advertises COG_ID (ADR-101/102 device-registry shape)
* client_id includes node_id (lesson from ADR-115 iter 45-48 session
takeover post-mortem — two publishers sharing a client_id loop)
* tls defaults to Off for v1 LAN-only (lock against silent enablement)
* default_identity carries CARGO_PKG_VERSION + PID for uniqueness
Plus the existing 2 manifest tests → 10/10 green
(`cargo test -p cog-ha-matter --no-default-features --lib`).
Also lands the deep-researcher dossier (`docs/research/ADR-116-ha-...`)
that the ADR §3+§4 reference — it was produced last iter but only the
ADR was committed; this puts the source-of-truth into the tree so the
ADR's "8 sections, 30+ citations" claim is actually verifiable.
P3 status in the ADR phase table flipped from "pending" to "in progress"
with the helper named; next iter tokio::spawns publisher::run(...) in
main.rs and registers the mDNS responder.
