docs: spec for sequa adopt (detect/convert existing DB tooling) - #29
Merged
Conversation
Design for a deterministic pipeline that fingerprints a project's DB tooling (sqlc/golang-migrate/goose/dbmate/atlas/…) and detects/plans/ applies conversion into sequa. Covers the source-system matrix with per-transform determinism levels, the "sequa is its own oracle" method (dry-run the real analyzer for exact suitability), the adopt detect|plan|apply surface, and a measured-signal scoring rubric.

docs/specs/adopt.md— the design for a proposedsequa adoptcommand that deterministically detects a project's existing DB approach and suggests/performs conversion into sequa. Linked fromdocs/README.md.Highlights
readUpMigrations+AnalyzeQueriesin dry-run — proof per migration/query, not heuristics.sequa adopt {detect|plan|apply}— detect/plan read-only & fully deterministic; apply does only mechanical transforms, flagging the rest as TODO stubs.Docs-only; no code change. Grounded in a real trial across a tree of Postgres projects (models codegen proven on 11; engine gate proven on a SQLite project).
