Merge branch 'main' into feature/resetdata-docker-secrets-integration

Major milestone: CHORUS leader election is now fully functional!

## Key Features Implemented:

### 🗳️ Leader Election Core
- Fixed root cause: nodes now trigger elections when no admin exists
- Added randomized election delays to prevent simultaneous elections
- Implemented concurrent election prevention (only one election at a time)
- Added proper election state management and transitions

### 📡 Admin Discovery System
- Enhanced discovery requests with "WHOAMI" debug messages
- Fixed discovery responses to properly include current leader ID
- Added comprehensive discovery request/response logging
- Implemented admin confirmation from multiple sources

### 🔧 Configuration Improvements
- Increased discovery timeout from 3s to 15s for better reliability
- Added proper Docker Hub image deployment workflow
- Updated build process to use correct chorus-agent binary (not deprecated chorus)
- Added static compilation flags for Alpine Linux compatibility

### 🐛 Critical Fixes
- Fixed build process confusion between chorus vs chorus-agent binaries
- Added missing admin_election capability to enable leader elections
- Corrected discovery logic to handle zero admin responses
- Enhanced debugging with detailed state and timing information

## Current Operational Status:
✅ Admin Election: Working with proper consensus
✅ Heartbeat System: 15-second intervals from elected admin
✅ Discovery Protocol: Nodes can find and confirm current admin
✅ P2P Connectivity: 5+ connected peers with libp2p
✅ SLURP Functionality: Enabled on admin nodes
✅ BACKBEAT Integration: Tempo synchronization working
✅ Container Health: All health checks passing

## Technical Details:
- Election uses weighted scoring based on uptime, capabilities, and resources
- Randomized delays prevent election storms (30-45s wait periods)
- Discovery responses include current leader ID for network-wide consensus
- State management prevents multiple concurrent elections
- Enhanced logging provides full visibility into election process

-# CHORUS - Container-First P2P Task Coordination System
+# CHORUS – Container-First Context Platform (Alpha)
 
-CHORUS is a next-generation P2P task coordination and collaborative AI system designed from the ground up for containerized deployments. It takes the best lessons learned from CHORUS and reimagines them for Docker Swarm, Kubernetes, and modern container orchestration platforms.
+CHORUS is the runtime that ties the CHORUS ecosystem together: libp2p mesh, DHT-backed storage, council/task coordination, and (eventually) SLURP contextual intelligence. The repository you are looking at is the in-progress container-first refactor. Several core systems boot today, but higher-level services (SLURP, SHHH, full HMMM routing) are still landing.
 
-## Vision
+## Current Status
 
-CHORUS enables distributed AI agents to coordinate, collaborate, and execute tasks across container clusters, supporting deployments from single containers to hundreds of instances in enterprise environments.
+| Area | Status | Notes |
+| --- | --- | --- |
+| libp2p node + PubSub | ✅ Running | `internal/runtime/shared.go` spins up the mesh, hypercore logging, availability broadcasts. |
+| DHT + DecisionPublisher | ✅ Running | Encrypted storage wired through `pkg/dht`; decisions written via `ucxl.DecisionPublisher`. |
+| Election manager | ✅ Running | Admin election integrated with Backbeat; metrics exposed under `pkg/metrics`. |
+| SLURP (context intelligence) | 🚧 Stubbed | `pkg/slurp/slurp.go` contains TODOs for resolver, temporal graphs, intelligence. Leader integration scaffolding exists but uses placeholder IDs/request forwarding. |
+| SHHH (secrets sentinel) | 🚧 Sentinel live | `pkg/shhh` redacts hypercore + PubSub payloads with audit + metrics hooks (policy replay TBD). |
+| HMMM routing | 🚧 Partial | PubSub topics join, but capability/role announcements and HMMM router wiring are placeholders (`internal/runtime/agent_support.go`). |
 
-## Key Design Principles
+See `docs/progress/CHORUS-WHOOSH-development-plan.md` for the detailed build plan and `docs/progress/CHORUS-WHOOSH-roadmap.md` for sequencing.
 
-- **Container-First**: Designed specifically for Docker/Kubernetes deployments
-- **License-Controlled**: Simple environment variable-based licensing
-- **Cloud-Native Logging**: Structured logging to stdout/stderr for container runtime collection
-- **Swarm-Ready P2P**: P2P protocols optimized for container networking
-- **Scalable Agent IDs**: Agent identification system that works across distributed deployments
-- **Zero-Config**: Minimal configuration requirements via environment variables
+## Quick Start (Alpha)
 
-## Architecture
+The container-first workflows are still evolving; expect frequent changes.
 
-CHORUS follows a microservices architecture where each container runs a single agent instance:
-
-```
-┌─────────────────┐  ┌─────────────────┐  ┌─────────────────┐
-│   CHORUS Agent  │  │   CHORUS Agent  │  │   CHORUS Agent  │
-│   Container 1   │◄─┤   Container 2   │─►│   Container N   │
-└─────────────────┘  └─────────────────┘  └─────────────────┘
-         │                      │                      │
-         └──────────────────────┼──────────────────────┘
-                                │
-                    ┌─────────────────┐
-                    │  Container      │
-                    │  Network        │
-                    │  (P2P Mesh)     │
-                    └─────────────────┘
-```
-
-## Quick Start
-
-### Prerequisites
-
-- Docker & Docker Compose
-- Valid CHORUS license key
-- Access to Ollama endpoints for AI functionality
-
-### Basic Deployment
-
-1. Clone and configure:
 ```bash
 git clone https://gitea.chorus.services/tony/CHORUS.git
 cd CHORUS
 cp docker/chorus.env.example docker/chorus.env
-# Edit docker/chorus.env with your license key and configuration
+# adjust env vars (KACHING license, bootstrap peers, etc.)
+docker compose -f docker/docker-compose.yml up --build
 ```
 
-2. Deploy:
-```bash
-docker-compose -f docker/docker-compose.yml up -d
-```
+You’ll get a single agent container with:
+- libp2p networking (mDNS + configured bootstrap peers)
+- election heartbeat
+- DHT storage (AGE-encrypted)
+- HTTP API + health endpoints
 
-3. Scale (Docker Swarm):
-```bash
-docker service scale chorus_agent=10
-```
+**Missing today:** SLURP context resolution, advanced SHHH policy replay, HMMM per-issue routing. Expect log warnings/TODOs for those paths.
 
-## Licensing
+## Roadmap Highlights
 
-CHORUS requires a valid license key to operate. Set your license key in the environment:
+1. **Security substrate** – land SHHH sentinel, finish SLURP leader-only operations, validate COOEE enrolment (see roadmap Phase 1).
+2. **Autonomous teams** – coordinate with WHOOSH for deployment telemetry + SLURP context export.
+3. **UCXL + KACHING** – hook runtime telemetry into KACHING and enforce UCXL validator.
 
-```env
-CHORUS_LICENSE_KEY=your-license-key-here
-CHORUS_LICENSE_EMAIL=your-email@example.com
-```
+Track progress via the shared roadmap and weekly burndown dashboards.
 
-**No license = No operation.** CHORUS will not start without valid licensing.
-
-## Differences from CHORUS

+# Decision Record: Establish SHHH Sentinel Foundations
+
+- **Date:** 2025-02-16
+- **Status:** Accepted
+- **Context:** CHORUS roadmap Phase 1 requires a secrets sentinel (`pkg/shhh`) before we wire COOEE/WHOOSH telemetry and audit plumbing. The runtime previously emitted placeholder TODOs and logged sensitive payloads without guard rails.
+
+## Problem
+- We lacked a reusable component to detect and redact secrets prior to log/telemetry fan-out.
+- Without a dedicated sentinel we could not attach audit sinks or surface metrics for redaction events, blocking roadmap item `SEC-SHHH`.
+
+## Decision
+- Introduce `pkg/shhh` as the SHHH sentinel with:
+  - Curated default rules (API keys, bearer/OAuth tokens, private key PEM blocks, OpenAI secrets).
+  - Extensible configuration for custom regex rules and per-rule severity/tags.
+  - Optional audit sink and statistics collection for integration with COOEE/WHOOSH pipelines.
+  - Helpers to redact free-form text and `map[string]any` payloads used by our logging pipeline.
+
+## Rationale
+- Starting with a focused set of high-signal rules gives immediate coverage for the most damaging leak classes without delaying larger SLURP/SHHH workstreams.
+- The API mirrors other CHORUS subsystems (options, config structs, stats snapshots) so existing operators can plug metrics/audits without bespoke glue.
+- Providing deterministic findings/locations simplifies future enforcement (e.g., WHOOSH UI badges, COOEE replay) while keeping implementation lean.
+
+## Impact
+- Runtime components can now instantiate SHHH and guarantee `[REDACTED]` placeholders for sensitive fields.
+- Audit/event plumbing can be wired incrementally—hashes are emitted for replay without storing raw secrets.
+- Future roadmap tasks (policy driven rules, replay, UCXL evidence) can extend `pkg/shhh` rather than implementing ad-hoc redaction in each subsystem.
+
+## Related Work
+- Roadmap: `docs/progress/CHORUS-WHOOSH-roadmap.md` (Phase 1.2 `SEC-SHHH`).
+- README coverage gap noted in `README.md` table (SHHH not implemented).

+# CHORUS / WHOOSH Roadmap
+
+_Last updated: 2025-02-15_
+
+This roadmap translates the development plan into phased milestones with suggested sequencing and exit criteria. Durations are approximate and assume parallel work streams where practical.
+
+## Phase 0 – Kick-off & Scoping (Week 0)
+- Confirm owners and staffing for SLURP, SHHH, COOEE, WHOOSH, UCXL, and KACHING work streams.
+- Finalize engineering briefs for each deliverable; align with plan in `CHORUS-WHOOSH-development-plan.md`.
+- Stand up tracking board (Kanban/Sprint) with milestone tags introduced below.
+
+**Exit Criteria**
+- Owners assigned and briefs approved.
+- Roadmap milestones added to tracking tooling.
+
+## Phase 1 – Security Substrate Foundations (Weeks 1–4)
+- **1.1 SLURP Core (Weeks 1–3)**
+  - Implement storage/resolver/temporal components and leader integration (ticket group `SEC-SLURP`).
+  - Ship integration tests covering admin-only operations and failover.
+- **1.2 SHHH Sentinel (Weeks 2–4)**
+  - Build `pkg/shhh`, integrate with COOEE/WHOOSH logging, add audit metrics (`SEC-SHHH`).
+- **1.3 COOEE Mesh Monitoring (Weeks 3–4)**
+  - Validate enrolment payloads, instrument mesh health, document ops runbook (`SEC-COOEE`).
+
+**Exit Criteria**
+- SLURP passes integration suite with real context resolution.
+- SHHH redaction events visible in metrics/logs; regression tests in place.
+- COOEE dashboards/reporting operational; runbook published.
+
+## Phase 2 – WHOOSH Data Path & Telemetry (Weeks 4–8)
+- **2.1 Persistence & API Hardening (Weeks 4–6)**
+  - Replace mock handlers with Postgres-backed endpoints (`WHOOSH-API`).
+- **2.2 Analysis Ingestion (Weeks 5–7)**
+  - Pipeline real Gitea/n8n analysis into composer/monitor (`WHOOSH-ANALYSIS`).
+- **2.3 Deployment Telemetry (Weeks 6–8)**
+  - Persist deployment results, emit telemetry, surface status in UI (`WHOOSH-OBS`).
+- **2.4 Composer Enhancements (Weeks 7–8)**
+  - Add LLM skill analysis with fallback heuristics; evaluation harness (`WHOOSH-COMP`).
+
+**Exit Criteria**
+- WHOOSH API/UI reflects live database state.
+- Analysis-derived data present in team formation/deployment flows.
+- Telemetry events available for KACHING integration.
+
+## Phase 3 – Cross-Cutting Governance & Tooling (Weeks 8–12)
+- **3.1 UCXL Spec & Validator (Weeks 8–10)**
+  - Publish Spec 1.0, ship validator CLI with CI coverage (`UCXL-SPEC`).
+- **3.2 KACHING Telemetry (Weeks 9–11)**
+  - Instrument CHORUS runtime & WHOOSH orchestrator, deploy ingestion/aggregation jobs (`KACHING-TELEM`).
+- **3.3 Governance Tooling (Weeks 10–12)**
+  - Deliver DR templates, signed assertions workflow, scope-aware RUSTLE views (`GOV-TOOLS`).
+
+**Exit Criteria**
+- UCXL validator integrated into CI for CHORUS/WHOOSH/RUSTLE.
+- KACHING receives events and triggers quota/budget alerts.
+- Governance docs/tooling published; RUSTLE displays redacted context correctly.
+
+## Phase 4 – Stabilization & Launch Readiness (Weeks 12–14)
+- Regression testing across CHORUS/WHOOSH/UCXL/KACHING.
+- Security & compliance review for SHHH and telemetry pipelines.
+- Rollout plan: staged deployment, rollback procedures, support playbooks.
+
+**Exit Criteria**
+- All milestone tickets closed with QA sign-off.
+- Production readiness review approved; launch window scheduled.
+
+## Tracking & Reporting
+- Weekly status sync covering milestone burndown, risks, and cross-team blockers.
+- Metrics dashboard to include: SLURP leader uptime, SHHH redaction counts, COOEE peer health, WHOOSH deployment success rate, UCXL validation pass rate, KACHING alert volume.
+- Maintain Decision Records for key architecture/security choices at relevant UCXL addresses.

+// Package shhh provides the CHORUS secrets sentinel responsible for detecting

+// focuses on predictable failure modes (log emission, telemetry fan-out,
+// request forwarding) and offers a composable API for registering additional
+// redaction rules, emitting audit events, and tracking operational metrics.
+//
+// The initial implementation focuses on high-signal secrets (API keys,
+// bearer/OAuth tokens, private keys) so the runtime can start integrating
+// SHHH into COOEE and WHOOSH logging immediately while the broader roadmap
+// items (automated redaction replay, policy driven rules) continue landing.

+
+[![GoDoc](https://godoc.org/github.com/sony/gobreaker?status.svg)](http://godoc.org/github.com/sony/gobreaker)
+
+[gobreaker][repo-url] implements the [Circuit Breaker pattern](https://msdn.microsoft.com/en-us/library/dn589784.aspx) in Go.
+
+Installation
+------------
+
+```
+go get github.com/sony/gobreaker
+```
+
+Usage
+-----
+
+The struct `CircuitBreaker` is a state machine to prevent sending requests that are likely to fail.
+The function `NewCircuitBreaker` creates a new `CircuitBreaker`.
+
+```go
+func NewCircuitBreaker(st Settings) *CircuitBreaker
+```
+
+You can configure `CircuitBreaker` by the struct `Settings`:
+
+```go
+type Settings struct {
+	Name          string
+	MaxRequests   uint32
+	Interval      time.Duration
+	Timeout       time.Duration
+	ReadyToTrip   func(counts Counts) bool
+	OnStateChange func(name string, from State, to State)
+	IsSuccessful  func(err error) bool
+}
+```
+
+- `Name` is the name of the `CircuitBreaker`.
+
+- `MaxRequests` is the maximum number of requests allowed to pass through
+  when the `CircuitBreaker` is half-open.
+  If `MaxRequests` is 0, `CircuitBreaker` allows only 1 request.
+
+- `Interval` is the cyclic period of the closed state
+  for `CircuitBreaker` to clear the internal `Counts`, described later in this section.
+  If `Interval` is 0, `CircuitBreaker` doesn't clear the internal `Counts` during the closed state.
+
+- `Timeout` is the period of the open state,
+  after which the state of `CircuitBreaker` becomes half-open.
+  If `Timeout` is 0, the timeout value of `CircuitBreaker` is set to 60 seconds.
+
+- `ReadyToTrip` is called with a copy of `Counts` whenever a request fails in the closed state.
+  If `ReadyToTrip` returns true, `CircuitBreaker` will be placed into the open state.
+  If `ReadyToTrip` is `nil`, default `ReadyToTrip` is used.
+  Default `ReadyToTrip` returns true when the number of consecutive failures is more than 5.
+
+- `OnStateChange` is called whenever the state of `CircuitBreaker` changes.
+
+- `IsSuccessful` is called with the error returned from a request.
+  If `IsSuccessful` returns true, the error is counted as a success.
+  Otherwise the error is counted as a failure.
+  If `IsSuccessful` is nil, default `IsSuccessful` is used, which returns false for all non-nil errors.
+
+The struct `Counts` holds the numbers of requests and their successes/failures:
+
+```go
+type Counts struct {
+	Requests             uint32
+	TotalSuccesses       uint32
+	TotalFailures        uint32
+	ConsecutiveSuccesses uint32
+	ConsecutiveFailures  uint32
+}
+```
+
+`CircuitBreaker` clears the internal `Counts` either
+on the change of the state or at the closed-state intervals.
+`Counts` ignores the results of the requests sent before clearing.
+
+`CircuitBreaker` can wrap any function to send a request:
+
+```go
+func (cb *CircuitBreaker) Execute(req func() (interface{}, error)) (interface{}, error)
+```
+
+The method `Execute` runs the given request if `CircuitBreaker` accepts it.
+`Execute` returns an error instantly if `CircuitBreaker` rejects the request.
+Otherwise, `Execute` returns the result of the request.
+If a panic occurs in the request, `CircuitBreaker` handles it as an error
+and causes the same panic again.
+
+Example
+-------
+
+```go
+var cb *breaker.CircuitBreaker
+
+func Get(url string) ([]byte, error) {
+	body, err := cb.Execute(func() (interface{}, error) {
+		resp, err := http.Get(url)
+		if err != nil {
+			return nil, err
+		}
+
+		defer resp.Body.Close()
+		body, err := ioutil.ReadAll(resp.Body)
+		if err != nil {
+			return nil, err
+		}
+
+		return body, nil
+	})
+	if err != nil {
+		return nil, err
+	}
+
+	return body.([]byte), nil
+}
