@hackage/settei-dhall

Use the family-standard lens package in test suites instead of the leftover microlens prototype dependency.
Add renderDhallErrorText and renderDhallErrorsText for stable, operator-readable, secret-safe adapter diagnostics with optional source positions.

Initial experimental release.
Add typed Dhall-to-Settei translation with NoImports and LocalImportsWithin policies.
Retain root and transitive import-closure provenance without claiming unavailable leaf-level import attribution.
Document that import-policy preflight and file reads are not atomic, so an untrusted-writable import root remains vulnerable to a time-of-check/time-of-use race.
Add optional one-based line and column fields to DhallSourceError, expose them through dhallErrorLine and dhallErrorColumn, and populate them for root and local-import parse failures.
