ADR-009, open-questions.md, and the architect agent spec all had the same
conflation: 'two-way door' was phrased as 'can be decided during
implementation,' which reads as 'defer the decision.' That's not what it
means. A two-way door is a decision you make now and can revert later if
wrong — it's about reversal cost, not urgency.
ADR-009: add §'What this framework is NOT' — explicitly separates door
type (reversal cost) from deferral (scope management). State that
architecture decisions are the architect's regardless of door type.
Reword the two-way-door process from 'can be decided during
implementation' to 'pick the simplest option that works, implement it,
revert if needed.'
open-questions.md: reword the header to clarify door type describes
reversal cost, not urgency. Add 'Door type is separate from whether a
decision is made.'
architect.md: add Key Principle #8 (decisions are made, not deferred),
a new 'Door Types and Decision Urgency' section, and two new anti-patterns
(#8: door type as deferral, #9: hedging language in resolved decisions).
Rename the crate from alknet-secret to alknet-vault to better reflect its
purpose as a local key vault (seed management, key derivation, encryption)
rather than a network service.
Symbol renames:
- SecretService → VaultService
- SecretServiceHandle → VaultServiceHandle
- SecretServiceActor → VaultServiceActor
- SecretServiceError → VaultServiceError
- SecretProtocol → VaultProtocol
- SecretMessage → VaultMessage
- ServiceLocked → VaultLocked
- alknet_secret → alknet_vault (crate name)
Update ADR-008 with vault access pattern: the vault is a capability source,
not a service endpoint. The CLI injects derived/decrypted material into
operation contexts — handlers never hold vault references.
