• Add the opt-in liveday benchmark for comparing raw Dart and focused packs across installed coding CLIs, plus one recorded sample and pack-vs-raw charts. The pack arm is read-only context and does not request a DMP reply.
• Publish a balanced-v1 savings table in the README from the checked-in medium-commerce scenario.
• stats reports compact-versus-pack packSavings and accepts pack focus flags (--symbol, --declaration, --task, --max-tokens, --max-bytes).
• DartMinifyWorkflow.apply parses planned sources and analyzes the affected closure by default.
• CI compares medium_scenario.dart stdout with the canonical JSON on stable Dart.
• Removed unused ValidationResult / ValidationIssue types. Protocol and path validation still throw their dedicated exceptions.
• Removed the unused isWithinCanonicalRoot helper and the leftover .llm.min.dart generated-file suffix.
• computeContentHash now reuses sha256String.
• Dropped the unused encodeCanonicalJson alias.
• Require dart_style 3.x for formatting compatibility.
• Skip unparsable files and redundant cache rebuilds during indexing.
• Format edits with the project Dart version and compact packed declaration source.
• Reserve the empty dictionary in the protocol.
• Default CLI verification tests off and analysis on during apply.

This is a breaking redesign from a whole-file minifier into a bidirectional, provider-agnostic agent codec.

Added #

• Analyzer-backed, deterministic source compaction with significant-token equivalence and structured malformed-source diagnostics.
• Content-addressed Dart and Flutter project indexes with stable file and declaration IDs, dependency relationships, hashes, and cache invalidation.
• Task-focused packs with explicit inclusion reasons, hard budgets, dependency stubs, and incremental session state.
• Provider-neutral first-turn and follow-up instruction preambles with project/base/session identity descriptors and measured overhead.
• Canonical protocol v2 in compact text and JSON forms.
• Declaration, directive, and file edit operations anchored by stable IDs, fingerprints, and expected base hashes.
• Atomic multi-file preflight and application with dry-run previews and local transaction records.
• Opt-in apply-time semantic closure analysis over planned in-memory sources, with pre-existing analyzer errors subtracted from the failure set.
• Parse, format, analyze, test, and custom-command verification with normalized diagnostics and focused repair-pack selection.
• The index, pack, apply, verify, stats, and doctor command surface, including per-command help and injected-stdin support where applicable.
• CI coverage for Dart 3.9 and latest stable Dart, formatting, analysis, tests, coverage artifacts, and package publication validation.

Changed #

• Raised the minimum Dart SDK to 3.9.
• Narrowed analyzer support to the tested 8.x API family.
• Redefined statistics to separate raw bytes, lexical tokens, estimated model tokens, and compact-protocol overhead.
• Kept machine-readable stdout separate from progress and diagnostic stderr.
• Moved local cache and session state under .dart_minify/; recoverable transaction journals remain at the project root as .dart_minify.transaction.*, with transaction-owned temporary files beside their targets for same-filesystem replacement.

Fixed #

• Preserve significant token boundaries for separated operators such as - - and for tokens separated only by removed comments.
• Correctly preserve raw, triple, interpolated, escaped, multiline, and Unicode string contents through analyzer tokenization.
• Reject malformed Dart, corrupt/truncated protocol input, unsupported protocol versions, duplicate operations, stale bases, and unsafe paths explicitly.
• Use canonical containment checks instead of lexical path-prefix checks.
• Preflight every file operation before committing any source change.

Removed #

• The minify, expand, lossy-build, and apply-lossy commands.
• Framed <<<DART_MINIFY_FILE:...>>> payloads and whole-source reverse maps.
• The build-runner builder, build.yaml, and the package's build and build_runner dependencies.
• .llm.min.dart, .llm.map.json, and lossy-manifest source workflows.
• Both 0.1.x symbol-renaming strategies and regex-based reverse renaming.

See the migration guide for command and artifact replacements.

• Prepare package for pub.flutter-io.cn publishing.
• Pin local Flutter toolchain via .fvmrc (3.41.4) for consistent development.
• Improve package metadata in pubspec.yaml (homepage/repository/issues/docs/topics).
• Rewrite README for clearer purpose, quickstart, and command guidance.
• Add runnable examples under example/ (CLI flow and Dart wrapper).
• Add MIT LICENSE.

• Initial release of dart_minify CLI.
• Added minify, expand, stats, doctor, lossy-build, and apply-lossy.
