## Signal Model (Simplified)

```python
@dataclass
class Signal:
    signal_id: str              # SHA256 hash
    source: str                 # voice, teams, calendar, notes
    timestamp: str              # ISO 8601
    raw_text: str               # Original content
    signal_type: str            # requirement, decision, question, insight, action_item
    prd_target: str | None      # ops_log, experiment_manager, operator_dashboard, researcher_dashboard
    people: list[str]           # Mentioned people
    detail: str                 # LLM-extracted summary
    confidence: float           # 0.0-1.0
    
    # Metadata
    source_file: str
    extracted_at: str
```

### Signal Types for PRD Work

| Type | Description | Example |
|------|-------------|---------|
| `requirement` | User need or feature request | "Operators need to see last 30 min of status checks" |
| `decision` | Design or scope decision made | "We'll use append-only log entries, no edits" |
| `question` | Open question needing resolution | "Should experiment log be separate from ops log?" |
| `insight` | Stakeholder context or constraint | "Jim mentioned regulations require 2-year retention" |
| `action_item` | Task to complete | "Schedule follow-up with Nick on sample tracking" |

## Prompts

### Signal Extraction Prompt

```python
SIGNAL_EXTRACTION_PROMPT = """
You are extracting actionable signals from meeting notes, voice memos, and transcripts 
for a operations platform project (Axiom).

Target PRDs (tag signals to the most relevant):
- ops_log: Operations logging, console checks, shift handoffs, compliance
- experiment_manager: Sample tracking, experiment lifecycle, supervisor approval, chain of custody
- operator_dashboard: Real-time operator view, compliance status, alerts
- researcher_dashboard: Researcher experiment view, sample status, results

Signal Types:
- requirement: A user need or feature request
- decision: A design or scope decision that was made
- question: An open question needing resolution
- insight: Stakeholder context, constraint, or background
- action_item: A task that needs to be done

Known Stakeholders:
- Jim (TJ): Operations Manager, compliance expert
- Nick Luciano: Senior Operator, daily ops perspective
- Khiloni Shah: Graduate researcher, experiment workflow
- Kevin Clarno: Program lead, cross-project visibility
- Ben Booth: Product owner, technical lead

Extract signals as JSON array:
```json
[
  {
    "signal_type": "requirement",
    "prd_target": "ops_log",
    "people": ["Jim"],
    "detail": "Operators need to see gap alerts if console check is >35 minutes overdue",
    "raw_quote": "Jim mentioned that 30 minutes is the rule but we should alert at 35...",
    "confidence": 0.85
  }
]
```

Only extract signals that are actionable or informative for the PRDs.
Skip small talk, tangents, and non-product discussions.
Attribute to people when clearly identifiable.

Transcript to process:
{transcript}
"""
```

### PRD Section Synthesis Prompt

```python
PRD_SECTION_PROMPT = """
You are updating a Product Requirements Document (PRD) for Axiom, 
a digital operations platform.

PRD: {prd_name}
Existing Requirements Section:
{existing_section}

New signals to incorporate:
{signals_json}

Generate a Markdown section that:
1. Lists new requirements extracted from signals
2. Uses format: REQ-{prd_code}-XXX (e.g., REQ-OPS-042)
3. Attributes each requirement to its source (person, date, signal type)
4. Notes any open questions or conflicts
5. Does NOT duplicate existing requirements
6. Preserves any existing requirement numbers

Output format:
```markdown
### Requirements from Stakeholder Input (Auto-extracted {date})

#### REQ-{code}-XXX: {Title}
**Source:** {person} via {source} ({date})  
**Type:** {Functional|Non-functional|Constraint}  
**Priority:** {P0|P1|P2} (based on signal context)

{Description}

**Rationale:** {Why this matters}

**Open Questions:**
- {Any unresolved items}

---
```

Be specific. Use exact quotes where helpful. Don't invent requirements not in signals.
"""
```

### Design Briefing Prompt

```python
BRIEFING_PROMPT = """
You are writing a design briefing document to kick off UI/UX design work 
for a Axiom module.

Module: {module_name}
Purpose: {module_purpose}
Target Users: {user_personas}

Signals from past 2 weeks:
{signals_json}

Write a 750-1200 word briefing narrative that:

1. **Context** (100 words): What this module does, who uses it, why it matters
2. **What We Learned** (400-600 words): 
   - Key insights from stakeholders (attribute by name)
   - Requirements that emerged
   - Constraints discovered (regulatory, technical, workflow)
   - Use direct quotes where impactful
3. **Decisions Made** (100 words): Any design decisions already locked in
4. **Open Questions** (100 words): Questions for design to resolve
5. **Recommended Next Steps** (100 words): Prioritized actions

Tone: Clear, direct, actionable. Write for a designer who hasn't been in the meetings.

End with a "Source Signals" section listing signal IDs for traceability.
"""
```

## Appendix B: Full Capstone Vision Reference

This MVP is Phase 0 of the full Sense & Synthesis Platform. The complete vision includes:

- **Multi-target synthesis:** Documents, spreadsheets, presentations, emails, calendar events, social media
- **LLM-first curation:** Auto-publish with human override as exception
- **Viewer personalization:** Same signals synthesized differently per user role
- **Federation:** Cross-org signal sharing with OpenFGA authorization (RBAC + ReBAC + ABAC)
- **Federated learning:** Privacy-preserving model improvement across organizations
- **Management dashboard:** Users control their information ecosystem

See: `docs/specs/sense-synthesis-capstone-spec.md` (to be created after Phase 0)

---

*This spec is designed to be self-contained for implementation. Claude should be able to implement each component given this context plus the existing sense module code.*
