convertlib

Differential-fuzz every convertlib codec against external reference implementations (dart:convert, base_codecs, base32) with full-domain inputs and a reproducible seed. Use before releases, after touching any encoder/decoder or alphabet table, or when asked to "fuzz", "cross-check", or "audit" the codecs. Finds the class of bug that roundtrip tests structurally cannot (wrong-alphabet tables, masking errors).

Scaffold a new codec or a new alphabet variant for convertlib the house way - generated alphabet tables, codec class with static const instances, top-level to/from functions, the six standard test groups with differential checks, README/CHANGELOG/example updates, and exports. Use when adding any new encoding (a new baseN, a new alphabet like base58/base85/z85, or a new format codec).

Run the exact checks convertlib CI runs, locally, before any commit or release. Use before committing, when asked "is this ready", "run the checks", or as the first step of a release. Catches format drift, analyzer infos, vm/node test failures, and integration breakage without waiting 20 minutes for the GitHub Actions matrix.

Cut a convertlib release end to end - version choice, CHANGELOG, pubspec bump, atomic release commit, vX.Y.Z tag, push, CI watch, pub.dev verification, and the follow-up dependency bump in ~/projects/hashlib. Use when asked to release, publish, ship, cut a version, or tag. Prevents the tag/pubspec-mismatch failure that killed v3.1.1.
