+# ADR-283: RuView community metaharness and verified learning flywheel
+
+| Field | Value |
+|---|---|
+| Status | Accepted — P0/P1 implemented |
+| Date | 2026-07-28 |
+| Builds on | ADR-182, ADR-263, ADR-265 |
+
+## Decision
+
+Extend `harness/ruview` as the single contributor automation boundary for
+repository exploration, development, debugging, testing and release
+preparation. The published package remains runtime-dependency-free.
+
+Two local hosts are supported with executable contracts:
+
+- Claude Code uses non-interactive `claude -p --safe-mode`, JSON output, no
+  session persistence, plan mode, and only read/search tools by default.
+- Codex uses `codex exec -`, a trusted `-C` root, `read-only` sandbox,
+  ephemeral sessions, strict config parsing, ignored user config/exec rules and
+  JSONL output.
+
+Both use shell-free subprocesses, stdin prompts, allowlisted environments,
+bounded output/time, secret redaction and realpath-based RuView checkout
+validation. Write mode requires two explicit flags and never uses permission or
+sandbox bypasses.
+
+## Shared brain
+
+The public brain is committed JSONL, not a shared mutable database. Canonical
+records are reviewed, bounded, source-relative, source-cited and content
+digested. Secret-shaped and instruction-shaped submissions are quarantined.
+Community learning enters through ordinary proposal pull requests.
+
+Ruflo/AgentDB may build local semantic indexes and private overlays from that
+corpus. Those indexes, raw transcripts, credentials and personal/CSI data are
+not committed. This provides a common brain without turning retrieved text into
+executable policy.
+
+## Darwin and Flywheel
+
+The seven policy surfaces are explicit in `flywheel/genome.json`. Evolution is
+human-initiated and each Darwin candidate may mutate only one surface.
+Contributor runs produce untrusted `.metaharness/` artifacts.
+
+Promotion is conjunctive:
+
+1. the frozen anchor cannot regress;
+2. the holdout must improve;
+3. legacy and security tests pass;
+4. no blocked action or secret exposure occurs;
+5. corpus, files and gate fingerprints verify;
+6. a maintainer reviews and approves the replay bundle.
+
+Flywheel signatures establish bundle integrity, not maintainer authority.
+Authority comes from protected-branch review and release provenance. CI never
+autonomously promotes or publishes an evolved candidate.
+
+## Consequences
+
+Contributors can explore RuView with either major local CLI and share durable
+findings without sharing secrets. Improvements become reproducible proposals
+with frozen evaluation evidence. The cost is a larger development-only npm
+lockfile, a 128 KiB unpacked-package budget (the current tarball is below that
+bound), and explicit maintenance of the corpus, genome and gate.

+# Observability: OTLP log export
+
+The sensing server can export every `tracing` log event as an
+OpenTelemetry log record over OTLP, with a curated set of sensing events
+(presence transitions, vitals estimates, node online/offline, fall
+detections, CSI capture stats, MQTT errors, model loads) carrying
+registry-backed event names and attributes under the `ruview.*`
+namespace.
+
+## The event registry
+
+The names are not ad hoc: they are defined in a weaver-validated
+semantic-conventions registry at `semconv/registry/` (attributes and log
+event names, OpenTelemetry registry format). The Rust constants module
+`v2/crates/wifi-densepose-sensing-server/src/semconv.rs` is **generated**
+from that registry (`weaver registry generate`, template under
+`templates/registry/rust/`) and CI (`.github/workflows/semconv.yml`)
+fails if either the registry stops validating or the generated module
+drifts. Executed Rust tests additionally reject any hard-coded
+`ruview.*` instrumentation key that is absent from the generated registry.
+Exported resources carry the registry's schema URL so downstream consumers
+can identify the exact conventions version.
+
+Curated events:
+
+| Event | Emitted when |
+| --- | --- |
+| `ruview.node.online` | first frame from a sensing node (CSI or edge vitals) |
+| `ruview.node.offline` | node evicted after 60 s without frames |
+| `ruview.presence.changed` | smoothed presence classification flips (transition-only) |
+| `ruview.vitals.estimate` | periodic breathing / heart-rate estimate (every 100 ticks) |
+| `ruview.fall.detected` | edge-vitals fall flag rising edge, per node |
+| `ruview.csi.stats` | periodic capture snapshot: frames processed, active nodes |
+| `ruview.mqtt.error` | MQTT publish/connection error in the HA publisher |
+| `ruview.model.loaded` | inference model loaded via the model API |
+
+## Enabling export
+
+Export is doubly gated so the default build and the default runtime are
+both unaffected:
+
+1. **Build** with the `otel` cargo feature (compiles in the OTLP
+   exporter stack, same gating principle as `mqtt`):
+
+   ```sh
+   cargo build --release -p wifi-densepose-sensing-server --features mqtt,otel
+   ```
+
+2. **Run** with `OTEL_EXPORTER_OTLP_ENDPOINT` set (unset ⇒ the OTLP
+   pipeline is never constructed and logging behaves exactly as before):
+
+   ```sh
+   OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317 \
+   ./target/release/sensing-server --source simulated
+   ```
+
+Use an `https://` collector endpoint outside a trusted local network. The
+`otel` feature includes Rustls and native certificate roots; standard OTLP
+environment variables can supply authentication headers. The Compose example
+uses plaintext only for container-to-container traffic on its private network.
+
+Logs export with resource attribute `service.name = "ruview"` and schema URL
+`https://raw.githubusercontent.com/ruvnet/RuView/main/semconv/schema/ruview-0.1.0.yaml`.
+Curated sensing
+events are emitted only after the configured exporter initializes
+successfully; without it, the pre-existing stderr output is unchanged.
+
+## Full stack: `docker compose`
+
+`docker/otel-compose.yml` brings up the whole pipeline —
+sensing server (synthetic CSI by default) → OpenTelemetry Collector →
+[Ourios](https://github.com/jensholdgaard/ourios), an OTLP-native log
+backend built on Parquet + online log-template mining + DataFusion:
+
+```sh
+docker compose -f docker/otel-compose.yml up
+```
+
+The collector and backend image tags are pinned to immutable multi-platform
+digests so the demo resolves to the reviewed images.
+
+Ourios derives the tenant from `service.name`, so all RuView logs land
+in tenant `ruview`.
+
+## Example queries
+
+Ourios mines every log line into a stable `template_id` online at
+ingest, which makes template-level questions cheap. Its query endpoint
+speaks a small logs DSL:
+
+Which log templates dominate RuView's output?

 ## Tools (`ruview_*`)

@@ -54,8 +53,58 @@ The bundled `.claude/settings.json` registers the `ruview` MCP server

 ## Hosts

-claude-code (bundled), and via metaharness host adapters: codex, opencode, copilot,
-pi-dev, hermes, rvm, github-actions.
+Claude Code and Codex are implemented directly and tested with the local,
+non-interactive CLIs:
+
+```bash
+npx @ruvnet/ruview agent run --host claude-code --repo . --prompt "Map the sensing-server startup path"
+npx @ruvnet/ruview agent run --host codex --repo . --prompt "Find the nearest tests for HomeCore restore state"
+```
+
+Prompts travel over stdin, never through a shell. Both adapters are read-only by
+default (`claude -p --safe-mode` in plan mode; `codex exec` in its read-only
+sandbox with user config and exec rules ignored), use a scrubbed environment,
+bound output/time, redact secrets, and require a trusted RuView checkout.
+Workspace writes require both `--allow-write` and `--confirm`; dangerous bypass
+flags are never emitted.
+
+## Shared contributor brain
+
+The committed `brain/corpus/core.jsonl` is a small, reviewable source of
+repository facts. Every record has a source citation, evidence tier, tags, and
+review state:
+
+```bash
+npx @ruvnet/ruview brain search --query "darwin community memory"
+npx @ruvnet/ruview brain verify --repo .
+npx @ruvnet/ruview brain propose --id finding-id --title "Finding" \
+  --content "Source-bound observation" --sourcePath README.md --sourceLine 1 \
+  --tags onboarding,docs --contributor github-user
+```
+
+Proposals are unreviewed JSONL for a normal pull request. Local vector indexes,
+private overlays, raw agent transcripts, CSI/person data, and credentials are
+never part of the shared corpus. Retrieved text is quoted evidence, not an
+instruction or authority grant.
+
+## Ruflo + Darwin/Flywheel
+
+Development tooling is exact-pinned in `devDependencies`: `metaharness@0.4.1`,
+`@metaharness/darwin@0.8.0`, and `@metaharness/flywheel@0.1.7`. Ruflo remains an
+optional contributor coordinator rather than cold-start weight for the
+dependency-free published MCP server:
+
+```bash
+claude mcp add --scope project ruflo -- npx -y ruflo@3.32.26 mcp start
+codex mcp add ruflo -- npx -y ruflo@3.32.26 mcp start
+```
+
+`npm run flywheel:plan` is read-only. Darwin execution is human-triggered with
+`node flywheel/run.mjs --confirm`; it writes only an untrusted
+`.metaharness/` proposal archive. The protected gate requires frozen-anchor
+retention, holdout lift, security and legacy-test success, verified provenance,
+and human approval. No contributor run can directly replace or publish the
+champion.
