- lint-staged for staged file linting
Pre-push Hooks - Full CI checks before pushing:

Page Type System - Consolidated URL classification:
- 22 page types: pricing, status, privacy, terms, security, changelog, docs, blog, product, legal, careers, partners, api, roadmap, support, availability, billing, returns, shipping, accessibility, events, entertainment, other
- detectPageType() function with URL pattern matching
- Integrated into AI summarization context
Use Cases Expansion - Product documentation:
- Expanded from 60 to 150 use cases
- Now covers 15 personas (was 6)
- New personas: Investor, Marketer, Product Manager, Sales Rep, Recruiter, Deal Hunter, Entertainment Fan, Traveler, Parent
Changelog System - Automated generation:
- scripts/generate-changelog.ts - Parses conventional commits
- docs/changelog/ directory with README and unreleased.md
- Groups by date with type subheadings
Database Indexes - Performance optimization:
- Added missing indexes for common query patterns
- Migration add_missing_indexes applied
Soak Testing Infrastructure - Pre-MVP Validation 1 (System Quality):
- scripts/phase1-verify.ts - Comprehensive system check
- scripts/soak-run-once.ts / scripts/soak-status.ts
- Verification artifacts in docs/runbooks/artifacts/
- Status: ✅ Complete (5+ days soak testing, all invariants passing)

Pre-MVP Validation Status

Sequential validation phases that must pass before MVP launch (see docs/runbooks/):

Phase	Runbook	Purpose	Status
1	pre-mvp-validation-1-system.md	System quality & signal correctness	✅ Complete
2	pre-mvp-validation-2-cost-stress.md	Cost sustainability & stress testing	⏳ Not started
3	pre-mvp-validation-3-early-users.md	Early user value validation	⏳ Not started

Validation 1 Evidence: 5+ days of soak testing (Dec 30 - Jan 4), all 3 invariants passing (no duplicate checks, no baseline changes, no baseline summaries).

Readiness Scorecard

Target	Previous	Current	Gap
Production ready	94%	96%	Coverage thresholds
V1 launch ready	98%	99%	Email tests, minor polish
vNext ready	87%	89%	API layer, history gating UI
Scale ready	84%	87%	Rate limiting
Team onboarding	98%	99%	Excellent docs, Drizzle guide
Design system	93%	93%	Component tests, accessibility
