Port a new ballerina/<name> stdlib package from jBallerina to this Go-native interpreter. Use when the user asks to migrate, port, or add a Ballerina standard library module that does not yet exist under `lib/stdlibs/ballerina/`. For filling gaps in an existing stdlib, use `fill-stdlib-gap` instead.
Authoritative format contract for `lib/stdlibs/ballerina/<name>/0.0.1/go1.26/README.md` files. Use when creating or updating any stdlib README, or when auditing an existing one for consistency.
Validate that a ballerina/<name> stdlib's Go public contract does not break the jBallerina public interface. Use when asked to validate, check, or verify a stdlib's public contract against jBallerina, or to review a stdlib PR for public-interface breakage. Produces a summary report at CONTRACT_VALIDATION.md. For porting a new stdlib use `add-stdlib-support`; for filling a gap use `fill-stdlib-gap`.
Fill a gap in an existing ballerina/<name> stdlib — implement a function marked Not Yet Supported, promote a Partially Supported row, or fix a behavioural divergence. Use when the target stdlib already exists under `lib/stdlibs/ballerina/`. For brand-new stdlibs, use `add-stdlib-support`.
