Package accesspolicies discovers and decodes the DALgo access policies a DataTug user keeps on disk, runs a query through them as a secured application would, and explains what the policies did to that query.

Package dbcopy implements the `datatug db copy` cross-engine database copy primitive.

Package httpsource translates a datatug project's HTTP-type QueryDefs into a dalgo2http-backed dal.DB: one dalgo2http.Collection per query (see BuildCollection for the translation and its sensible-default policy for RowsPath/KeyField, since the QueryDef JSON schema does not yet carry those explicitly), snapshot fallback wired to the project's fixtures/http/ directory (see fixtureFS for how its flatly-named fixture files are bridged to dalgo2http's per-request snapshot keying), live-then-snapshot mode.

Package secureread is the policy-enforced read executor for the DataTug agent server (`datatug serve`).

Package sneatv keeps the small compatibility surface used by datatug-cli while filetug's UI helpers live in dedicated packages.
