Tosumu Architectural Review Records
Architectural Review Records preserve unresolved questions, implementation or consumer pressure, evidence, alternatives, findings, dispositions, and reopening criteria. They sit between informal notes and binding ADRs.

ADR
Open A Review When
- ownership between storage core, relational layers, adapters, and consumers is unclear;
- a file-format or compatibility change is proposed;
- a new stable public contract or cross-layer dependency is proposed;
- repeated implementation friction suggests an existing boundary is wrong;
- corpus or independent-consumer evidence may reopen an accepted decision;
- a proposal is deferred or rejected and its reasoning should remain durable.
Use AR-NNNN-short-title.md. Review numbering is independent from ADR
numbering. Copy TEMPLATE.md and add the record to this index.

Index
- AR-0001: TQL Command Language Boundary -- incubating ownership, lowering, and structured-outcome boundaries for the Tosumu operator command surface.
- AR-0002: Structured Inspection Contract Boundary -- incubating the provider-neutral inspection snapshot boundary below CLI serialization.
- AR-0003: Service Authority And Host Modes -- incubating embedded, daemon, and remote host ownership without admitting distributed storage.
- AR-0004: Semantic Change History And Sync -- separating application mutations and sync evidence from the physical WAL.
- AR-0005: Witness, Observer, And Freshness -- preserving the distinction between authenticated local integrity and externally anchored freshness.
- AR-0006: Format Evolution And Migration Boundary -- holding pre-stability format evolution and migration policy open until a concrete incompatible change exists.
