## Fixed brief and assumptions

Include authority, latency, offline, concurrency, accessibility, security, privacy,
performance and recovery constraints. Mark unspecified requirements explicitly.

## Baseline narrative without the pattern catalog

Describe a plausible architecture and its trade-offs for comparison.

## Decisions

| Order | Context and forces | Pattern references | Alternatives and rejection reasons | Resulting context | Evidence |
| --- | --- | --- | --- | --- | --- |

## Change one constraint

State the change and trace its impact through the decisions and pattern relations.

## Failure and recovery

Describe stale reads, rejected mutations, interruption and partial failure as applicable.

## Review

| Criterion | Pass / revise / unknown | Evidence and reason |
| --- | --- | --- |
| Traceability | | |
| Coherence of configuration | | |
| Decision usefulness beyond baseline | | |
| Quality constraints | | |
| Changed-constraint branch | | |

## Gaps and follow-up

Record missing patterns, invalid relations, ordering failures and work record links.
