Resolve blocking one-way door decisions: - ADR-007: BiStream is a trait, handlers receive Connection not BiStream - ADR-008: Secret service is CLI-embedded, exposed via call protocol - ADR-009: One-way door decision framework (classify by reversal cost) Update existing documents: - overview.md: add design principles, revise ProtocolHandler signature, update shared types, add WASM as design constraint - open-questions.md: add door-type classifications, resolve OQ-01/OQ-08, move OQ-09/OQ-10 to deferred section, mark two-way doors as impl-deferred - README.md: reflect resolved questions, remove crate spec stubs from index - ADR-002: cross-reference ADR-007 for signature revision Clean up premature artifacts: - Remove 11 empty crate spec stubs (16-28 lines each, no unique content) - Specs will be created when each crate enters Phase 1

# Alknet Architecture
|
||
|
||
## Current State
|
||
|
||
**Pre-implementation.** The project has completed a pivot from a three-layer model to an ALPN-as-service model. The greenfield workspace contains only `alknet-secret` (stable) and research/reference material. Foundational ADRs (001–009) are in place, including the BiStream type definition (ADR-007), secret service integration (ADR-008), and the one-way door decision framework (ADR-009). Architecture specs are ready for Phase 1 implementation planning.
|
||
|
||
**Next step**: Resolve remaining two-way-door questions during implementation. Start with alknet-core (ProtocolHandler trait, Connection, endpoint, router, auth types, config).
|
||
|
||
## Architecture Documents
|
||
|
||
| Document | Status | Description |
|
||
|----------|--------|-------------|
|
||
| [overview.md](overview.md) | draft | Workspace-level overview, crate graph, shared types, design principles |
|
||
| [open-questions.md](open-questions.md) | draft | Centralized OQ tracker with door-type classifications |
|
||
|
||
Crate-specific specs will be created when each crate is ready for Phase 1 architecture work, not in advance.
|
||

## Open Questions
|
||
|
||
See [open-questions.md](open-questions.md) for the full tracker.
|
||
|
||
**Resolved one-way doors:**
|
||
- **OQ-01**: BiStream type — trait with Connection parameter (ADR-007)
|
||
- **OQ-02**: AuthContext timing — hybrid model (ADR-004)
|
||
- **OQ-03**: ALPN naming — `alknet/` prefix, no version (ADR-006)
|
||
- **OQ-06**: ALPN per connection, not per stream (ADR-006)
|
||
- **OQ-08**: Secret service — CLI-embedded via call protocol (ADR-008)
|
||
|
||
**Two-way doors (deferred to implementation):**
|
||
- **OQ-04**: Dynamic handler registration — start static, add ArcSwap later
|
||
- **OQ-05**: Multi-transport endpoint — start with quinn, add transport trait later
|
||
- **OQ-07**: Call protocol scope — start with one stream per operation
|
||
|
||
**Deferred (not active):**
|
||
- **OQ-09**: WASM target boundaries — design constraint, not deliverable
|
||
- **OQ-10**: Git adapter scope — start with smart protocol, add ERC721 later

## Document Lifecycle
|
||
|
||
| Status | Meaning | Transitions |
|
||
|--------|---------|-------------|
|
||
| `draft` | Under active development. May change significantly. | → `reviewed` when open questions are resolved |
|
||
| `reviewed` | Architecture is final. Implementation may begin. Changes require review. | → `stable` when implementation is complete and verified |
|
||
| `stable` | Locked. Changes require review and may warrant an ADR. | → `deprecated` when superseded |
|
||
| `deprecated` | Superseded. Kept for reference. | Removed when no longer referenced |
