Position video transcription workflow in framework architecture with ADR-015

[Copilot]

Analyzed the video transcription documentation pipeline concept and positioned it within the agent-augmented development framework, defining agent roles, decision boundaries, and integration patterns.

Deliverables

Architectural Analysis

docs/architecture/synthesis/video-transcription-pipeline-analysis.md (38KB)

• Framework alignment: integrates with ADRs 001, 003, 004, 005, 008, 009, 013, 014 without architectural drift
• Five agent roles with explicit boundaries: Recorder (ingestion), Transcriber (STT), Analyzer (extraction), Writer (generation), Reviewer (validation)
• Decision boundaries: automated vs. manual, LLM integration points at Analysis and Generation stages
• Privacy boundaries: content sensitivity classification (public/internal/confidential/sensitive), local-only transcription for sensitive content
• Reusability: generalizes to podcast/webinar/interview/training transcription

ADR-015: Video Transcription Pipeline Integration

docs/architecture/adrs/ADR-015-video-transcription-pipeline-integration.md (17KB)

Multi-stage pipeline extending existing file-based coordination (ADR-008) and task lifecycle patterns (ADR-003):

User → Recorder → Transcriber → Analyzer → Writer → Reviewer → Published Docs
         │            │             │          │         │
         └─ YAML ─────┴─ YAML ──────┴─ YAML ───┴─ YAML ──┴─ Complete

Key decisions:

• Whisper (local) for sensitive content, API services optional for non-sensitive
• 90-day retention for raw videos, permanent for processed transcripts and docs
• Mandatory traceability: video timestamps + transcript references in all generated docs
• 4-phase rollout: PoC (manual) → semi-automated → fully automated → production

Metrics (ADR-009):

• Processing time <48hrs (ingestion → published)
• Transcription confidence ≥90%
• Coverage ≥80% of key meetings
• Time savings ≥70% vs manual

Module Outline

docs/architecture/design/video-transcription-module-outline.md (22KB)

Complete module structure with:

• Agent profiles, directives (016: workflow, 017: privacy)
• Configuration templates (transcription services, quality thresholds, privacy policy, storage paths)
• Scripts (ingest, setup, run-pipeline, validate, cleanup-retention)
• Deployment checklist and integration points

Pattern Reusability

The pipeline is an instance of a general pattern:

[Rich Media] → [Text Extraction] → [Semantic Analysis] → [Structured Output] → [Documentation]

Applicable to podcasts, webinars, customer interviews, training sessions—any audio/video content requiring documentation.

Changes

• Added: docs/architecture/synthesis/video-transcription-pipeline-analysis.md
• Added: docs/architecture/adrs/ADR-015-video-transcription-pipeline-integration.md
• Added: docs/architecture/design/video-transcription-module-outline.md
• Added: work/task-39-validation-summary.md
• Modified: docs/architecture/adrs/README.md (added ADR-015 to index)

Review Focus

• Agent role boundaries appropriate?
• Privacy classification sufficient?
• Phased rollout plan reasonable?
• Integration points with existing ADRs correct?

<issue_title>Task: Position video transcription workflow in architectural analysis</issue_title>
<issue_description>### Parent Feature

#36 (Epic: Easy Documentation Pipelines)

Task Description

Architect to process and analyze the documented video transcription idea: position the workflow in framework architecture, define agent roles (Recorder, Extractor, Redactor, Polisher, Publisher), clarify decision boundaries, and ensure traceable patterns are applied. Output module outline and propose ADR.

Implementation Steps

1. Analyze workflow alignment with framework
2. Define agent roles for the pipeline
3. Document decision/LLM/privacy boundaries
4. Identify reusability in framework
5. Draft ADR for architectural integration
6. Outline module for documentation pipeline

Acceptance Criteria

• Analysis document exists in analysis/
• Agent roles are explicitly listed
• Boundaries, patterns, and reusability documented
• ADR draft for pipeline module included

Task Type

Design

Effort Estimate

M (4-8 hours)

Assigned Agent / Person

No response

Dependencies

• Blocked by: Epic: Easy Documentation Pipelines (Local → Hybrid → Cloud) #36, video transcription doc

Validation Steps

1. Analysis reviewed for alignment/traceability
2. Roles and patterns traceable to workflow
3. ADR exists; module documented

Notes

Ensures solution is architecturally sound and reusable.</issue_description>

Intentionally keeping this branch stale, will try to see if the agents can rebase / re-fresh stale branches.
