Add architecture beliefs to manifesto and enhance software-architecture skill

Browse Source 
- Add Architecture Beliefs section to manifesto with outcome-focused beliefs:
  auditability, business language in code, independent evolution, explicit over implicit
- Create software-architecture.md as human-readable documentation
- Enhance software-architecture skill with beliefs→patterns mapping (DDD, Event
  Sourcing, event-driven communication) and auto-trigger description
- Update work-issue command to reference skill and check project architecture
- Update issue-worker agent with software-architecture skill
- Add Architecture section template to vision-management skill

The skill is now auto-triggered when implementing, reviewing, or planning
architectural work. Project-level architecture choices go in vision.md.

### Architecture Beliefs
We believe certain outcomes matter more than others when building systems:
- **Auditability by default.** Systems should remember what happened, not just current state. History is valuable - for debugging, compliance, understanding, and recovery.
- **Business language in code.** The words domain experts use should appear in the codebase. When code mirrors how the business thinks, everyone can reason about it.
- **Independent evolution.** Parts of the system should change without breaking other parts. Loose coupling isn't just nice - it's how small teams stay fast as systems grow.
- **Explicit over implicit.** Intent should be visible. Side effects should be traceable. When something important happens, the system should make that obvious.
See [software-architecture.md](./software-architecture.md) for the patterns we use to achieve these outcomes.

# Software Architecture # Software Architecture
Best practices, patterns, and review guidance for software architecture. This skill serves as the knowledge base for architecture-related agents and commands. Architectural patterns and best practices. This skill is auto-triggered when implementing, reviewing, or planning work that involves architectural decisions.
## Architecture Beliefs
These outcome-focused beliefs (from our organization manifesto) guide architectural decisions:
| Belief | Why It Matters |
|--------|----------------|
| **Auditability by default** | Systems should remember what happened, not just current state |
| **Business language in code** | Domain experts' words should appear in the codebase |
| **Independent evolution** | Parts should change without breaking other parts |
| **Explicit over implicit** | Intent and side effects should be visible and traceable |
## Beliefs → Patterns
| Belief | Primary Pattern | Supporting Patterns |
|--------|-----------------|---------------------|
| Auditability by default | Event Sourcing | Immutable events, temporal queries |
| Business language in code | Domain-Driven Design | Ubiquitous language, aggregates, bounded contexts |
| Independent evolution | Event-driven communication | Bounded contexts, published language |
| Explicit over implicit | Commands and Events | Domain events, clear intent |
## Event Sourcing
**Achieves:** Auditability by default
Instead of storing current state, store the sequence of events that led to it.
**Core concepts:**
- **Events** are immutable facts about what happened, named in past tense: `OrderPlaced`, `PaymentReceived`
- **State** is derived by replaying events, not stored directly
- **Event store** is append-only - history is never modified
**Why this matters:**
- Complete audit trail for free
- Debug by replaying history
- Answer "what was the state at time X?"
- Recover from bugs by fixing logic and replaying
**Trade-offs:**
- More complex than CRUD for simple cases
- Requires thinking in events, not state
- Eventually consistent read models
## Domain-Driven Design
**Achieves:** Business language in code
The domain model reflects how the business thinks and talks.
**Core concepts:**
- **Ubiquitous language** - same terms in code, conversations, and documentation
- **Bounded contexts** - explicit boundaries where terms have consistent meaning
- **Aggregates** - clusters of objects that change together, with one root entity
- **Domain events** - capture what happened in business terms
**Why this matters:**
- Domain experts can read and validate the model
- New team members learn the domain through code
- Changes in business rules map clearly to code changes
**Trade-offs:**
- Upfront investment in understanding the domain
- Boundaries may need to shift as understanding grows
- Overkill for pure technical/infrastructure code
## Event-Driven Communication
**Achieves:** Independent evolution
Services communicate by publishing events, not calling each other directly.
**Core concepts:**
- **Publish events** when something important happens
- **Subscribe to events** you care about
- **No direct dependencies** between publisher and subscriber
- **Eventual consistency** - accept that not everything updates instantly
**Why this matters:**
- Add new services without changing existing ones
- Services can be deployed independently
- Natural resilience - if a subscriber is down, events queue
**Trade-offs:**
- Harder to trace request flow
- Eventual consistency requires different thinking
- Need infrastructure for reliable event delivery
## Commands and Events
**Achieves:** Explicit over implicit
Distinguish between requests (commands) and facts (events).
**Core concepts:**
- **Commands** express intent: `PlaceOrder`, `CancelSubscription`
- Commands can be rejected (validation, business rules)
- **Events** express facts: `OrderPlaced`, `SubscriptionCancelled`
- Events are immutable - what happened, happened
**Why this matters:**
- Clear separation of "trying to do X" vs "X happened"
- Commands validate, events just record
- Enables replay - reprocess events with new logic
## When to Diverge
These patterns are defaults, not mandates. Diverge intentionally when:
- **Simplicity wins** - a simple CRUD endpoint doesn't need event sourcing
- **Performance requires it** - sometimes synchronous calls are necessary
- **Team context** - patterns the team doesn't understand cause more harm than good
- **Prototyping** - validate ideas before investing in full architecture
When diverging, document the decision in the project's `vision.md` Architecture section.
## Project-Level Architecture
Each project documents architectural choices in `vision.md`:
```markdown
## Architecture
This project follows organization architecture patterns.
### Alignment
- Event sourcing for [which aggregates/domains]
- Bounded contexts: [list contexts and their responsibilities]
- Event-driven communication between [which services]
### Intentional Divergences

# Software Architecture
> **For Claude:** This content is mirrored in `skills/software-architecture/SKILL.md` which is auto-triggered when relevant. You don't need to load this file directly.
This document describes the architectural patterns we use to achieve our [architecture beliefs](./manifesto.md#architecture-beliefs). It serves as human-readable organizational documentation.
