Milestone Lifecycle Coordinator¶

Overview and Purpose¶

The MilestoneLifecycleCoordinator is a core orchestrator in the ConnectSoft AI Software Factory.
It governs the lifecycle, validation, and promotion of milestones by coordinating:

Feature delivery across one or more sprints
Validation of output artifacts, coverage, traceability
Emission of milestone status events (e.g., MilestoneReached, MilestoneBlocked)
CI/CD and release integration based on milestone success

Milestones in the Factory are not deadlines — they are delivery gates defined by traceable, testable, and reviewable criteria.

🎯 Key Responsibilities¶

Function	Description
Monitor Sprint Results	Wait for all sprints mapped to the milestone to emit `SprintClosed`
Validate Gates	Check test coverage, artifact presence, trace completion, and QA status
Emit Lifecycle Events	Signal milestone state: `MilestoneReady`, `MilestoneBlocked`, `MilestoneReached`
Trigger Downstream Steps	When gates are passed, emit promotion signals to `ReleaseCoordinator`, `PipelineGenerator`, etc.
Support Manual Override	Allow Studio users to force-close or pause milestones with full trace context

📦 Core Input¶

The coordinator watches the Factory’s milestones.yaml for all milestone definitions:

milestones:
  - id: mvp-ready
    requiredFeatures:
      - BookingFlow
      - Notification.Email.Send
      - Auth.Login
    gateConditions:
      - allSprintsClosed
      - testCoverageAbove: 90
      - traceMatrixComplete
    versionTag: mvp-v1

### 🧠 Value in the Factory

The `MilestoneLifecycleCoordinator` ensures that:

* Every release gate is tied to verifiable output
* Features across parallel sprints are **logically grouped and validated**
* Manual and automated decision points are both **traceable and auditable**

It enables **incremental, modular, and observable delivery** across hundreds of services and teams.

---

## Position in the Execution Flow

The `MilestoneLifecycleCoordinator` sits at the **critical junction between sprint execution and promotion to release**.  
It governs **when a milestone can be declared complete**, based on validated outputs from one or more sprints.

> It transforms sprint outputs into a milestone-level decision — acting as a delivery gatekeeper and orchestrated promotion controller.

---

### 🧭 Execution Phase Role

| Factory Phase              | Role of MilestoneLifecycleCoordinator |
|-----------------------------|----------------------------------------|
| 📦 **Sprint Execution**      | Listens for `SprintClosed` events from all sprints tied to this milestone |
| 🔍 **Trace Validation**      | Gathers outputs and trace matrix from each sprint to verify feature coverage |
| ✅ **Gate Evaluation**       | Enforces milestone gate rules (e.g., `qaCoverageAbove`, `traceMatrixComplete`) |
| 🚀 **Release Trigger**       | If all gates pass, emits `MilestoneReached` and notifies release orchestrators |
| 🛑 **Blocking State**        | Emits `MilestoneBlocked` if any sprint is missing, invalid, or test-incomplete |
| 🧑 **Manual Review Support** | Allows override or deferment from Studio for milestone approval gates |

### 📊 Impact on Studio Dashboards

* **Milestone Board View** shows current status per milestone (`Pending`, `Blocked`, `Reached`)
* **Gate Matrix** shows required features, coverage, test counts, and trace status
* **Promotion Log** captures all milestone transitions, overrides, and validations

---

### ✅ Summary

The `MilestoneLifecycleCoordinator` serves as the **final validator of milestone readiness**, translating distributed sprint outputs into a **single verifiable delivery decision**.

It ensures that milestones are only declared complete when all constituent work is:

* ✅ Executed
* 🧪 Tested
* 🔗 Traceable
* 🔍 Audited

---

## Responsibilities

The `MilestoneLifecycleCoordinator` is the Factory’s **milestone-level execution governor**. It consolidates sprint outputs, validates completion gates, emits milestone status events, and determines when downstream steps (e.g., deployment, tagging, freeze) can proceed.

This coordinator operates with a **delivery-first, trace-aligned mindset** — prioritizing completion only when all conditions are verifiably met.

---

### ✅ Core Responsibilities

| Responsibility                  | Description |
|----------------------------------|-------------|
| **Monitor Required Sprints**     | Wait for `SprintClosed` events from all sprints assigned to the milestone’s features |
| **Track Feature Completion**     | Cross-check `sprint-trace-matrix.json` with `milestones.yaml.requiredFeatures[]` |
| **Validate Milestone Gates**     | Ensure all conditions in `gateConditions[]` are met (e.g., coverage, trace integrity, security validation) |
| **Emit Milestone Events**        | `MilestoneReady`, `MilestoneReached`, `MilestoneBlocked`, `MilestoneEscalated` |
| **Support Manual Escalation**   | Enable Studio users to override gate failures via `MilestoneOverrideRequested` |
| **Trigger Promotion**            | On success, emit trigger event for downstream release/deploy/pipeline flows |

---

### 🧩 Milestone FSM Lifecycle

| State         | Transition Trigger               |
|---------------|----------------------------------|
| `Planned`      | Created from `milestones.yaml` or `MilestonePlanned` |
| `Pending`      | Waiting for required `SprintClosed` events |
| `Verifying`    | Evaluating trace matrices and QA metrics |
| `Reached`      | All gates satisfied, milestone completed |
| `Blocked`      | One or more unmet gates or missing outputs |
| `Escalated`    | Human action required to resolve exception |
| `Closed`       | Final state after promotion completes |

---

### 📘 Example: Gate Conditions Enforced

```yaml
milestones:
  - id: mvp-ready
    requiredFeatures:
      - BookingFlow
      - Notification.Email.Send
    gateConditions:
      - allSprintsClosed
      - qaCoverageAbove: 90
      - traceMatrixComplete
      - noManualOverridesActive
````

→ All conditions must be met before `MilestoneReached` can be emitted.

---

### 🔎 Additional Responsibilities

| Responsibility                         | Description                                                                            |
| -------------------------------------- | -------------------------------------------------------------------------------------- |
| **Validate CI/CD Readiness**           | Check if image tags, version metadata, and release markers exist in each sprint output |
| **Emit Observability Logs**            | Push milestone-level logs and metrics for dashboards and compliance views              |
| **Manage Timeouts / Orphaned Sprints** | Flag long-running or unclosed sprints tied to a milestone                              |

---

### ✅ Summary

The `MilestoneLifecycleCoordinator` ensures that milestones:

* Represent **fully validated delivery boundaries**
* Are only advanced when all **features, sprints, and outputs** are accounted for
* Serve as **promotion gates** for downstream orchestration

It acts as the **quality and completeness enforcer** of the AI Software Factory.

---

## Triggering Events

The `MilestoneLifecycleCoordinator` operates as an **event-driven state machine**, responding to upstream sprint completions and triggering downstream milestone transitions.

It listens for lifecycle events emitted by sprints, agents, and Studio — and emits milestone-specific signals to orchestrate promotion, block progression, or request review.

---

### 📥 Events Consumed (Triggers)

✅ Summary¶

The MilestoneLifecycleCoordinator emits:

🔁 Events for downstream orchestration
📂 Files for traceability and governance
📈 Metrics for observability and Studio feedback

This ensures milestones are visible, auditable, and actionable across the Factory’s delivery chain.

Collaborating Agents and Coordinators¶

The MilestoneLifecycleCoordinator does not operate in isolation — it collaborates with a range of agents and orchestrators to collect results, evaluate readiness, and trigger promotion.

Each component plays a specific role in feeding data into, or acting on decisions from, the milestone orchestration flow.

🤝 Key Collaborating Coordinators¶

Coordinator	Role
`SprintExecutionCoordinator`	Emits `SprintClosed` and `sprint-trace-matrix.json` per scoped sprint
`QAOrchestrator`	Validates QA status and forwards coverage reports
`ReleaseCoordinator`	Listens for `MilestoneReached` to trigger build promotion or deployment
`CI/CD Tagger` / `PipelineGenerator`	Uses milestone metadata to inject version tags and trigger build stages

🧠 Collaborating Agents¶

Agent	Role in Milestone Completion
`QAAgent`	Ensures test coverage, outputs `qa-validation-report.md`
`TestGeneratorAgent`	Generates tests needed to meet milestone test gate
`SecurityEngineerAgent`	Validates security gates (e.g., JWT enabled, span templates injected)
`ProductOwnerAgent`	Initiates milestone plan and can manually intervene on blocked gates
`HumanApprovalEscalator`	Triggered if `MilestoneEscalated` requires human resolution
`StudioUserAgent`	Represents manual governance actors via Studio UI

🧩 Coordination Flow Example¶

| `SecurityPolicyValidator`    | Artifact + Status | Block milestone if trace or policy checks fail |

---

### 🧠 Trace and Role Awareness

Each agent receives milestone-aware context such as:

```json
{
  "milestone_id": "mvp-ready",
  "requiredFeatures": ["BookingFlow", "SendEmail"],
  "trace_id": "trace-abc-999",
  "qaCoverageThreshold": 90,
  "manualOverrideAllowed": true
}

Hold "Alt" / "Option" to enable pan & zoom

Agents then report back status that affects milestone gate transitions.

✅ Summary¶

The MilestoneLifecycleCoordinator depends on a network of agents and orchestrators to:

🔍 Validate conditions
📤 Emit signals
🔁 React to failures or escalations
🚀 Promote delivery after successful validation

This makes milestone management modular, distributed, and policy-aware — consistent with the Factory’s event-driven design.

System Prompt¶

The MilestoneLifecycleCoordinator, like other orchestrators in the Factory, generates structured prompts when it interacts with agents or skills that support AI-driven execution (e.g., QA validation, security checks, documentation generation).

These prompts are context-rich, trace-anchored, and milestone-specific — guiding agents or plugins to perform scoped validation or reporting tasks.

🧠 Purpose of the Prompt¶

To instruct agents to:

Validate milestone completion conditions
Report trace coverage, test metrics, or missing elements
Emit summary documentation for traceability or audit
Inject promotion tags if the milestone is complete

📘 Prompt Template (Generic)¶

You are operating within the ConnectSoft AI Software Factory as a milestone governance agent.

Your current context:

- milestone_id: {{milestone_id}}
- version_tag: {{version_tag}}
- sprint_ids: {{sprint_ids}}
- trace_id: {{trace_id}}
- requiredFeatures: {{features}}
- gateConditions: {{gates}}

Please verify the following:
- All required features have completed trace-linked outputs
- Test coverage meets or exceeds the required threshold
- Security and trace metadata are present in all artifacts
- CI/CD promotion is authorized only if gates are met

Respond with a summary object and status.
````

---

### 📘 Example Prompt for `QAAgent` Plugin

```text
Milestone ID: mvp-ready  
Required Features: BookingFlow, Notification.Send  
Sprint IDs: sprint-1, sprint-2  
QA Threshold: 90%

Please analyze:
- QA coverage per feature from `qa-validation-report.md`
- Confirm that all required features are present in `sprint-trace-matrix.json`

Respond with:
{
  "milestone_id": "mvp-ready",
  "coverage": 91.3,
  "missing_features": [],
  "status": "passed"
}

📂 Variables Injected into the Prompt¶

Variable	Source
`milestone_id`	From `milestones.yaml`
`sprint_ids[]`	From received `SprintClosed` events
`requiredFeatures[]`	From milestone definition
`trace_id`	Latest milestone session or dominant sprint
`version_tag`	From milestone metadata
`gates[]`	Gate conditions like coverage, trace completeness, etc.

🔧 Used By¶

Target Agent or Skill	Use Case
`QAAgent`	Validate feature-test linkage and coverage
`SecurityEngineerAgent`	Confirm trace span injection and policy gates
`DocumentationAgent`	Generate milestone summary report
`StudioAuditSkill`	Provide audit digest for milestone promotion

🧾 Output Consumption¶

Structured JSON responses from these prompts are written to:

milestone-status.json
milestone-validation-report.md
promotion-trigger.yaml

…and used to trigger milestone state transitions (Reached, Blocked, Escalated).

✅ Summary¶

System prompts generated by the MilestoneLifecycleCoordinator are:

🧠 Intelligent — include full milestone and sprint scope
🧾 Structured — machine-parseable and traceable
🔁 Reusable — same prompt schema works across QA, Docs, Security

This ensures coordinated, AI-augmented milestone validation within trace boundaries.

Execution Flow (Steps)¶

The MilestoneLifecycleCoordinator operates through a structured, event-driven execution sequence, evaluating whether a milestone can progress from planning to promotion.
This flow is designed to be modular, retry-safe, and trace-anchored.

🔁 Step-by-Step Execution Flow¶

1. Receive `MilestonePlanned`¶

Load milestones.yaml
Initialize milestone FSM with status: Planned
Set required feature list, gate conditions, trace anchor, and version tag

2. Wait for All `SprintClosed` Events¶

Monitor sprints associated with requiredFeatures[]
For each closed sprint:
- Parse sprint-trace-matrix.json
- Validate feature-to-artifact linkage

3. Enter `Verifying` State¶

Aggregate QA reports (qa-validation-report.md)
Aggregate execution-metadata.json from all sprints
Evaluate milestone gateConditions[]

4. Evaluate Each Gate Condition¶

Examples: - ✅ allSprintsClosed: Match all requiredFeatures to completed sprints - ✅ qaCoverageAbove: 90: Aggregate coverage and compare - ✅ traceMatrixComplete: Check for feature-to-file + test mapping

If any gate fails:

Transition FSM to Blocked
Emit MilestoneBlocked

5. Optional Escalation or Override¶

Wait for MilestoneOverrideRequested from Studio
If override approved, proceed to close manually

6. Milestone Promotion¶

Emit MilestoneReached
Write milestone-status.json
Trigger MilestonePromotionTriggered for CI/CD coordination

7. Finalize State¶

Emit logs and metrics (duration, coverage, trace results)
Transition FSM to Closed
Notify Studio for dashboard update

📂 Generated Artifacts Per Step¶

Step	Artifacts
2	`milestone-sprint-map.json`
3	`milestone-gate-status.json`
5	`intervention-events.json`
6	`milestone-status.json`, `promotion-trigger.yaml`

🔁 Execution Characteristics¶

Feature	Enabled
Parallel Sprint Watch	✅
Partial Validation	✅ (Fails gate if incomplete)
FSM State Persistence	✅
Retry & Resume	✅
Manual Intervention	✅
Trace Anchoring	✅

✅ Summary¶

The milestone execution flow ensures that milestones are only reached if all functional and quality conditions are met, with options for:

🧠 Autonomous validation
🔁 Resumption after pause or failure
🧑 Manual override with trace justification

This makes milestone lifecycle management both automatable and governable.

🧠 Summary¶

These diagrams show:

📦 How milestone validation is linked to sprint outputs
🔐 How gate checks are evaluated in stages
🧑 Where human oversight may be required
🚀 How promotion is gated and triggered safely

This makes the milestone lifecycle transparent, auditable, and extensible.

Required Blueprints and Trace Inputs¶

The MilestoneLifecycleCoordinator requires structured, machine-readable inputs to operate effectively. These include milestone blueprints, trace matrices, test coverage reports, and agent execution metadata.

Together, these inputs allow the coordinator to determine:

Which features must be delivered
Which sprints have satisfied their scope
Whether traceability and QA conditions are met
When a milestone can be marked as complete

📘 Primary Blueprint: `milestones.yaml`¶

This file defines all milestone metadata and is the main input to initialize milestone tracking.

milestones:
  - id: mvp-ready
    description: MVP milestone for booking and notifications
    requiredFeatures:
      - BookingFlow
      - Notification.Email.Send
    gateConditions:
      - allSprintsClosed
      - qaCoverageAbove: 90
      - traceMatrixComplete
    versionTag: mvp-v1
    governedBy: product-owner
````

✅ Each milestone entry includes:

* ID and human-readable description
* Required feature list
* Gate conditions
* Optional promotion triggers

✅ Summary¶

To function reliably, the MilestoneLifecycleCoordinator depends on:

🎯 Blueprints — define scope and gate logic (milestones.yaml)
🔎 Trace inputs — validate delivery, coverage, and completion
🧾 Audit artifacts — track overrides and manual transitions

This guarantees data-driven, traceable, and consistent milestone decisions.

Semantic Kernel Skills and Plugins¶

The MilestoneLifecycleCoordinator can invoke Semantic Kernel skills and plugins to validate, report, summarize, or escalate milestone states using structured AI-powered workflows.

These skills operate on structured inputs (e.g., trace matrices, QA reports, milestone configs) and emit traceable, verifiable outputs.
They augment automation and reduce manual effort in milestone analysis.

✅ Summary¶

Semantic Kernel skills and plugins used by the MilestoneLifecycleCoordinator provide:

🧠 AI-assisted validation
🧾 Automated milestone summaries
🛑 Controlled override evaluation
🔗 Trace-linked output for promotion

This empowers the Factory to execute governed, explainable, and extensible milestone workflows.

Human Intervention Hooks¶

While the MilestoneLifecycleCoordinator is built for full automation, it includes structured intervention points where Studio users, approvers, or compliance officers can review, override, or resolve milestone states manually.

These hooks support governance, accountability, and trace-aligned decision-making — particularly in high-risk, QA-blocked, or compliance-sensitive deliveries.

🧑‍💼 Manual Review Scenarios¶

Scenario	Trigger
One or more required features not completed	`SprintClosed` missing or failed
QA coverage below required threshold	`qaCoverage < gateCondition`
Security validation failed	`SecurityGateValidationSkill → fail`
Trace matrix missing or incomplete	`traceMatrixStatus != complete`
Manual gate present (e.g., legal approval)	`manualGateStatus: pending`

🚨 Key Manual Hook Events¶

Event	Source / Target
`MilestoneBlocked`	Emitted by coordinator upon failed gate
`MilestoneEscalated`	Coordinator requests manual intervention
`MilestoneOverrideRequested`	Emitted by StudioUserAgent to request gate bypass
`MilestoneForceClosed`	Coordinator emits after manual override approved
`MilestoneResumed`	Allows milestone to re-enter validation after fix or retry

🧾 Override Context Format¶

{
  "milestone_id": "mvp-ready",
  "trace_id": "trace-xyz123",
  "overridden_gates": ["qaCoverageAbove"],
  "reason": "All tests passed except edge case not relevant to current customer.",
  "approver": "product-owner",
  "timestamp": "2025-05-15T18:44:00Z"

| ----------------------- | ---------------------------------------- |
| 🔍 View Gate Failures   | Show failed gates and unmet requirements |
| 📝 Submit Justification | Provide reason for override              |
| ✅ Approve Override      | Emit `MilestoneOverrideRequested`        |
| 🚫 Reject Promotion     | Block further attempts until fix         |
| 🔁 Resume Evaluation    | Re-run milestone check after correction  |

---

### 🔐 Approval Roles and Policy Tags

Milestones may specify allowed override roles in `milestones.yaml`:

```yaml
governedBy: product-owner
manualOverrideAllowed: true
approvalRoles:
  - qa-lead
  - domain-architect

→ Ensures only authorized users can intervene and that all actions are fully traceable.

📊 Observability Integration¶

Manual overrides appear as special span events (MilestoneOverride)
Interventions increment metrics:
milestone_override_count
milestone_manual_promotion
Trigger UI alerts and compliance flags in dashboards

✅ Summary¶

The MilestoneLifecycleCoordinator provides robust, trace-linked human intervention points, ensuring:

🔎 Reviewable milestone blockages
✅ Authorized and auditable overrides
🔁 Re-execution after manual fixes
📋 Full governance compatibility

These hooks empower the Factory to deliver governed autonomy — fast where possible, controlled where necessary.

Observability and Traceability¶

The MilestoneLifecycleCoordinator is deeply integrated with the Factory’s observability-first model.
All its lifecycle events, validations, failures, overrides, and promotions are trace-tagged, logged, and visualized in real time.

This ensures that every milestone decision is:

🔎 Inspectable
🧾 Auditable
🧠 Debuggable
📊 Measurable

📡 Trace Context Fields¶

All milestone-related telemetry and artifacts include the following identifiers:

Field	Description
`milestone_id`	The logical identifier of the milestone being tracked
`trace_id`	Root trace anchor across sprints, QA, and Studio events
`version_tag`	Tag emitted upon promotion trigger (e.g., `mvp-v1`)
`sprint_ids[]`	List of contributing sprints linked to required features
`gate_status[]`	Pass/fail per milestone gate condition
`coverage_percent`	Aggregated from all sprint QA reports
`intervention_id`	Optional — used when override is manually approved

📊 Emitted Metrics¶

Metric Name	Description
`milestone_gate_success_total`	# of milestones that passed all gates
`milestone_gate_failure_total`	# of blocked milestones
`milestone_manual_override_total`	# of milestones closed via human approval
`milestone_duration_seconds`	Time from `MilestonePlanned` to `MilestoneReached`
`milestone_trace_matrix_validated_total`	# of milestones with complete trace linkage
`milestone_qa_coverage_percent`	Aggregated QA coverage across linked features

→ Exposed via Prometheus, Azure Monitor, or OpenTelemetry pipelines

🧵 Trace Spans¶

Every major operation emits an OpenTelemetry span:

Span Name	Trigger
`MilestonePlanned`	On first registration
`MilestoneGateEvaluation`	During trace + QA validation
`MilestoneBlocked`	On gate failure
`MilestoneReached`	On promotion event
`MilestoneOverrideAccepted`	On manual approval
`MilestonePromotionTriggered`	When version promotion begins

📁 Logged Artifacts¶

File Name	Description
`milestone-status.json`	Final outcome (reached, blocked, escalated), gates, trace IDs
`milestone-validation-report.md`	Human-readable summary of pass/fail results
`intervention-events.json`	Logs of manual overrides with approvers, timestamps
`promotion-trigger.yaml`	Output to deployment system with version, tags, and approval state

🧭 Studio Dashboard Integration¶

Milestone trace data drives:

Status indicators (Pending, Blocked, Reached, Escalated)
Gate condition matrix (per milestone)
QA progress meters (feature × coverage)
Trace explorer (milestone → sprint → agent → artifact)
Audit timeline (event logs with trace IDs and roles)

✅ Summary¶

The MilestoneLifecycleCoordinator makes milestone delivery:

🧠 Trace-aware
🔍 Fully visible across systems
📈 Metrics-rich for analytics and optimization
🧾 Ready for audit and rollback when needed

Every decision — auto or manual — is anchored in trace context and observable across the Factory.

Configuration Options¶

The MilestoneLifecycleCoordinator is highly configurable, allowing it to adapt to various governance models, delivery patterns, and compliance requirements.

Configuration options can be defined:

Globally (via orchestration-config.yaml)
Per milestone (inside milestones.yaml)
Dynamically (via Studio override panel or event payloads)

These settings govern how gates are enforced, how strict trace validation is, and whether manual overrides are allowed.

⚙️ Global Configuration Example¶

MilestoneLifecycleCoordinator:
  autoPromotion: true
  defaultQACoverageThreshold: 90
  allowManualOverrides: true
  traceValidationRequired: true
  promotionTriggers:
    - deploy-to-staging
    - create-release-notes
  defaultGateTimeoutSeconds: 300
  retryOnFailure: true
  observability:
    emitSpans: true
    logLevel: info

| `defaultGateTimeoutSeconds`  | Max time to wait for gate resolution (e.g., sprint closure) before emitting `Blocked` |
| `promotionTriggers[]`        | Events to emit upon successful milestone (e.g., deploy, notify, tag)                  |

---

### 📘 Per-Milestone Override Example

In `milestones.yaml`:

```yaml
milestones:
  - id: auth-preview
    gateConditions:
      - allSprintsClosed
      - qaCoverageAbove: 85
    autoPromotion: false
    allowManualOverrides: false
    versionTag: v0.9-preview
    governedBy: qa-lead

Overrides global settings for this specific milestone, making promotion manual-only.

🧠 Dynamic Config via Studio¶

Studio UI can override live milestone state with:

QA thresholds
Coverage deferral
Manual intervention justification
Escalation trigger selection

Changes are persisted to:

intervention-events.json
milestone-status.json
Coordinator FSM checkpoint

🔐 Governance Role Control¶

approvalRoles:
  - qa-lead
  - compliance-officer

→ Only users with these roles can:

Approve overrides
Force promotion
Adjust milestone parameters live

✅ Summary¶

Configuration options make the MilestoneLifecycleCoordinator:

🎛️ Flexible across delivery styles (autonomous vs. controlled)
🔐 Governable via roles and thresholds
🧾 Policy-compliant via traceable overrides
🔁 Retry-safe for real-world execution

Milestones become programmable delivery gates, customizable per project and governance need.

Error Handling & Resilience¶

The MilestoneLifecycleCoordinator is built for robust operation in dynamic environments — where agent delays, partial outputs, or QA failures are expected.
It uses a resilient state machine, retry policies, and clear escalation paths to ensure milestone delivery remains stable and traceable.

🧯 Error Categories and Recovery Strategies¶

Error Type	Coordinator Behavior
Missing Sprint	FSM enters `Blocked`; waits for retry or override
QA Coverage Below Threshold	Triggers `Blocked` → `Escalated` state
Trace Matrix Incomplete	Logs error, disables promotion, and alerts Studio
Skill/Agent Timeout	Emits telemetry + `MilestoneBlocked`; retries if enabled
Unexpected File Format	Fails current validation step, logs parse error, requests re-run
CI/CD Promotion Trigger Fails	Emits `MilestonePromotionFailed`, retries or halts pipeline trigger

🔁 Retry Logic¶

Trigger Condition	Retry Behavior
Temporary file load failure	Retries up to 3 times (configurable)
Late `SprintClosed` event	Re-evaluates gates automatically
Agent/QA timeout	FSM waits for configurable delay, then reattempts
Promotion trigger failure	Retries promotion trigger via `PromotionRetry` span

Retries are tracked per milestone in: - retry-history.json - FSM checkpoint logs - Prometheus metrics (milestone_retry_count)

📘 FSM Recovery Path¶

stateDiagram-v2
    Verifying --> Blocked: GateFailure
    Blocked --> Verifying: RetryTriggered or ManualFix
    Blocked --> Escalated: Timeout or StudioEscalation
    Escalated --> Reached: OverrideApproved
    Blocked --> Terminated: MaxRetriesExceeded

### 🧾 Error Artifact Logging

| File                       | Purpose                                                  |
| -------------------------- | -------------------------------------------------------- |
| `milestone-status.json`    | Updated with `status: blocked`, failed gates, timestamps |
| `milestone-error-log.json` | Details for each failure: gate, reason, recovery path    |
| `intervention-events.json` | Logs override attempts and escalation resolutions        |
| `promotion-trigger.yaml`   | Removed or marked `pending` if milestone not eligible    |

---

### 🧠 Escalation Support

If all retries fail or human approval is needed:

* Coordinator emits `MilestoneEscalated`
* Studio is notified with reason and next steps
* Human roles (e.g., `qa-lead`) can issue `MilestoneOverrideRequested` to proceed

---

### 📊 Observability Metrics

| Metric                       | Description                                              |
| ---------------------------- | -------------------------------------------------------- |
| `milestone_retry_count`      | Total retry attempts per milestone                       |
| `milestone_blocked_total`    | Cumulative blocked milestone count                       |
| `milestone_escalation_count` | Count of manual escalations required                     |
| `milestone_timeout_seconds`  | Time spent in `Blocked` or `Escalated` before resolution |

---

### ✅ Summary

The `MilestoneLifecycleCoordinator` is **resilient-by-design**.
It handles transient failures gracefully, supports retry logic, and integrates human review paths when needed — ensuring milestone delivery is:

* 🔄 Recoverable
* 🔐 Governed
* 📊 Measurable
* 🧾 Trace-linked

---

## Integration with SprintExecutionCoordinator

The `MilestoneLifecycleCoordinator` works in tandem with the `SprintExecutionCoordinator` to ensure **sprints contribute meaningfully to milestone delivery**.  
This integration guarantees that only **validated**, **QA-complete**, and **trace-linked** sprints advance milestones toward release.

---

### 🔁 Event-Based Coordination

| From `SprintExecutionCoordinator`     | Consumed by `MilestoneLifecycleCoordinator` |
|--------------------------------------|----------------------------------------------|
| `SprintPlanned`                      | Optional, used to prepare tracking context   |
| `SprintClosed`                       | Triggers milestone validation for mapped features |
| `SprintBlocked`                      | Halts milestone verification; emits `MilestoneBlocked` |
| `execution-metadata.json` (per agent)| Used to validate trace span injection and artifact readiness |
| `sprint-trace-matrix.json`           | Parsed to verify feature completion, test coverage, and gate input |

---

### 📘 Flow: From Sprint Closure to Milestone Progress

1. **SprintExecutionCoordinator emits `SprintClosed`**
1. `MilestoneLifecycleCoordinator` receives event and:
     - Validates features covered in that sprint
     - Checks `qa-validation-report.md` and coverage %
     - Updates internal gate condition tracker
1. If all required features and QA gates are met:
     - Emits `MilestoneReached`  
     - Triggers `MilestonePromotionTriggered`

If any gates fail:

- Enters `Blocked`  
- Awaits retry, override, or further sprint input

---

### 📦 Shared Artifacts

| Artifact                    | Originating Coordinator | Used By |
|-----------------------------|--------------------------|---------|
| `sprint-trace-matrix.json`  | SprintExecutionCoordinator | Milestone gate evaluation |
| `execution-metadata.json[]` | Sprint agents              | Milestone trace span and artifact validation |
| `qa-validation-report.md`   | QAAgent                    | Gate evaluation (`qaCoverageAbove`) |
| `milestone-status.json`     | MilestoneLifecycleCoordinator | Studio, CI/CD, auditors |

---

### 🧠 Feature-Sprint-Milestone Mapping

| Feature              | Sprint ID           | Milestone ID   |
|----------------------|----------------------|----------------|
| `BookingFlow`         | `sprint-2025-06-core` | `mvp-ready`     |
| `SendEmail`           | `sprint-2025-06-core` | `mvp-ready`     |
| `RetryQueue`          | `sprint-2025-07-edge` | `stability-pass1` |

This mapping is used to ensure all milestone-required features have been delivered via one or more valid sprints.

---

### 🔁 Reusability

If a sprint contributes to multiple milestones (e.g., `core` and `stability`):

- Each milestone checks trace matrix independently  
- Artifacts and tests are reused but revalidated in context

---

### 🧩 FSM Transition Trigger

```mermaid
stateDiagram-v2
    Pending --> Verifying: SprintClosed (feature matched)
    Verifying --> Reached: All gates passed
    Verifying --> Blocked: Any gate failed
````

---

### ✅ Summary

The `MilestoneLifecycleCoordinator` depends on `SprintExecutionCoordinator` to:

* Deliver feature-ready artifacts
* Emit validation signals
* Provide complete trace and QA data

This creates a **closed loop of sprint-driven milestone advancement**, ensuring all promotions are:

* ✅ Verified
* 🔍 Traceable
* 📊 QA-covered
* 📦 CI/CD-ready

---

## Release Coordination and CI/CD Integration

The `MilestoneLifecycleCoordinator` is the **final gatekeeper** before release workflows are triggered.  
Once a milestone passes all validation gates, this coordinator emits structured outputs and events to **initiate CI/CD pipelines**, **version tagging**, and **deployment orchestration**.

It ensures that only trace-verified, QA-passed, and milestone-scoped artifacts are promoted into release.

---

### 🔁 Trace Explorer Integration

From any milestone:

* Navigate to contributing `sprint-trace-matrix.json`
* Inspect feature → artifact → test linkage
* View agent logs and span IDs
* Diff trace coverage by sprint or feature

---

### 📤 Promotion Snapshot

If milestone was promoted:

* ✅ Version shown (e.g., `v1.0.0-mvp`)
* 📦 CI/CD pipeline link
* 📝 Changelog summary
* 🔖 Git commit tag reference

---

### ✅ Summary

Studio visualizations make milestone delivery:

* 📊 Transparent for technical and non-technical stakeholders
* 🧭 Navigable across agents, artifacts, and sprints
* 🔍 Auditable with full trace history
* 📋 Governable with manual overrides and QA alerts

The result: **confidence in every milestone, every time**.
