From ea7b5711a12e16361de55289643f39537655bf62 Mon Sep 17 00:00:00 2001 From: ruv Date: Sun, 24 May 2026 19:49:16 -0400 Subject: [PATCH] feat(adr-118/p6.12): examples/bfld_minimal.rs operator quickstart (315/315 GREEN) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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, "rf_signature_hash":"blake3:cc3615c7aaab9d0867a0c15327444b8f...bf"} 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 — first operator-facing example shipped as part of the crate. Discoverable via `cargo run --example bfld_minimal` and verified via cargo test. Test config: - cargo test --no-default-features → 101 passed (example_minimal cfg-out) - cargo test → 315 passed (311 + 4 example_minimal) Out of scope (next iter target): - PR-readiness pivot still pending: CHANGELOG, witness bundle, AC closeout table. External-resource-gated work still skipped.
