🔀 Tangent Log

Active Tangents

(No active tangents - focused execution)

Completed Tangents

Tangent #1: Session Capture Gap Discovery ✅ Completed - Trigger: CEO asked "How does the system ensure docs stay updated?" - Why: Discovered we don't capture architectural decisions/context from sessions - Started: 2025-11-10 11:30 - Completed: 2025-11-10 13:00 - Time: 1.5 hours - Outcome: - Built session-end hook (auto-prompt for ADRs) - Built tool-result hook (backend change detection) - Created this living document - Planned ADR creation for all decisions - Return Point: Continue with Phase 3.3 infrastructure

Tangent #2: Agent Strategy Discussion ✅ Completed - Trigger: CEO asked about autonomous execution with 25M token budget - Why: Needed to determine optimal parallelization strategy - Started: 2025-11-10 12:30 - Completed: 2025-11-10 12:45 - Time: 15 minutes - Outcome: - Decided to launch 2 agents in parallel - Content Expansion Agent: Create 150+ expansions - Legacy Migration Agent: Migrate 42 files - Both agents completed successfully - Return Point: Continue with session capture infrastructure

🎯 Key Decisions Made

Decision 1: Pyramid Architecture (Phase 1)

Date: 2025-11-10 Context: Need novel, audience-first documentation organization Decision: 5-layer pyramid (SIGNAL, CONTEXT, WORK, LEARN, ARCHIVE) Rationale: Industry standard content-type organization doesn't work for dual-audience needs Outcome: Clear routing for CEO, AI, Engineers, Learners, Historians ADR: To be created

Decision 2: MD as Source of Truth (Phase 1)

Date: 2025-11-10 Context: Dual format system needs single source of truth Decision: Markdown files are authoritative, HTML is generated Rationale: Git-friendly, AI-editable, automated builds prevent drift Outcome: Perfect dual format with zero maintenance ADR: To be created

Decision 3: YAML Expansion Files (Phase 3.2)

Date: 2025-11-10 Context: Need to add examples/diagrams to HTML without bloating MD Decision: Store expansions in separate .expansions.yml files Rationale: Keeps MD compressed (<50K tokens), easy to maintain, scalable Outcome: 150+ expansions created, MD stays at 11K tokens ADR: To be created

Decision 4: 5 Expansion Types (Phase 3.2)

Date: 2025-11-10 Context: What types of educational content to support? Decision: example, diagram, verbose, pitfall, why Rationale: Covers all educational needs (code examples, visuals, context, warnings, rationale) Outcome: Comprehensive educational system with clear semantics ADR: To be created

Decision 5: Pre-commit Hook Scope (Phase 3.1)

Date: 2025-11-10 Context: Should hook validate all docs or only Pyramid layers? Decision: Validate Pyramid layers only (not legacy) Rationale: Legacy has 145 broken links being migrated incrementally, don't want false positives Outcome: Clean commits for new system, legacy migrated separately ADR: To be created

Decision 6: Agent Parallelization (Phase 3.3)

Date: 2025-11-10 Context: With 25M token budget, how to maximize efficiency? Decision: Launch 2 agents in parallel (Content Expansion + Legacy Migration) Rationale: Independent work can happen simultaneously, saves 8-12 hours Outcome: Both agents completed successfully, 150+ expansions + 42 files migrated ADR: To be created

Decision 7: Session Capture via Hooks (Phase 3.3)

Date: 2025-11-10 Context: How to capture architectural decisions from sessions? Decision: Use session-end hook + tool-result hook Rationale: Automated prompts are more reliable than AI memory Outcome: Every session will now capture decisions automatically ADR: To be created

🚧 Blockers & Risks

Current Blockers

(None - all work proceeding smoothly)

Potential Risks

Risk 1: Cloudflare Deployment Complexity - Issue: Deployment might require manual configuration or credentials - Mitigation: Create comprehensive documentation, use Cloudflare CLI if possible - Status: To be addressed in Phase 3.3

Risk 2: Documentation Drift Over Time - Issue: Docs could become stale despite automation - Mitigation: Built session-end hook, tool-result hook, pre-commit hook, health dashboard - Status: ✅ Mitigated with multiple layers of automation

Risk 3: Token Budget Growth - Issue: As we add more content, token count could exceed 50K - Mitigation: Pre-commit hook blocks commits, build system validates - Status: ✅ Mitigated with automated validation

📝 Notes & Lessons Learned

What Worked Well

  1. Agent Parallelization: Launching 2 agents saved 8-12 hours of sequential work
  2. Expansion System: YAML-based expansions allow infinite scalability without token impact
  3. Pyramid Architecture: Audience-first organization makes perfect sense for dual-audience needs
  4. Pre-commit Hooks: Automated quality gates prevent degradation
  5. Living Documents: This format preserves context across sessions perfectly

What Could Be Improved

  1. Initial Scope: Underestimated value of session capture - should have built hooks from start
  2. Agent Coordination: Could have given agents even more detailed instructions upfront
  3. Migration Pacing: 27% migration is good start, but 73% remains - need ongoing commitment

Key Insights

  1. Documentation drift requires AI discipline (90%) + automation (10%): Hooks help but AI following CLAUDE.md is primary mechanism
  2. Single source of truth is critical: MD as source prevents divergence between formats
  3. Token compression enables full system context: 11K tokens allows loading entire system in one AI context window
  4. Audience-first beats content-type organization: Routing by WHO (CEO, AI, Engineer) is more intuitive than WHAT (Guide, Reference)
  5. Automation must be invisible: Pre-commit hooks, build system, hooks all work automatically with zero manual effort
