Removed duplicate help text from doc comments:
- log.zig: Removed usage examples (in printUsage)
- annotate.zig: Removed usage examples (in printUsage)
- experiment.zig: Removed usage examples (in printUsage)
Rationale: printUsage() already contains detailed help text.
Doc comments should not duplicate this information.
All tests pass.
Fixed compilation error in jupyter/lifecycle.zig:
- Changed 'const client' to 'var client' in ConnectionCtx.init()
- Allows errdefer client.close() to work correctly
- close() requires mutable reference to ws.Client
All tests pass.
Created utils/dataset_hash.zig:
- computeDatasetHash(allocator, path) -> [64]u8
- Returns fixed 64-char hex string (stack allocated)
- Provides verifyDatasetIntegrity() for hash comparison
- Enables testing against native C++ implementations
Updated dataset.zig:
- verifyDataset() now automatically computes hash during verification
- Uses utils/dataset_hash.zig for hash computation
- Hash displayed in JSON output for reference
- No separate 'dataset hash' command needed
Benefits:
- Single source of truth for dataset hashing
- Testable independently for correctness verification
- Automatic during dataset verify operation
Since app is not released, removed old commands entirely:
- Deleted exec.zig (533 lines) - modularized version
- Deleted queue.zig (1248 lines) - complete removal
- Unified all functionality into run.zig
New unified 'ml run' command features:
- Auto-detects local vs remote execution via mode.detect()
- Supports --local and --remote flags to force execution mode
- Includes all resource options: --cpu, --memory, --gpu
- Research context: --hypothesis, --context, --intent, --tags
- Validation modes: --dry-run, --validate, --explain
- Uses modular exec/remote.zig and exec/local.zig for execution
Dispatcher updates (main.zig):
- Removed 'e' (exec) handler
- Removed 'q' (queue) handler
- Updated help text to show unified command
Import cleanup (commands.zig):
- Removed queue.zig import
Total code reduction: ~1,700 lines
All tests pass.

- Added /// doc comment with usage and subcommand descriptions
- Follows same format as other commands
Removed dataset_hash.zig:
- Hash computation is already automatic in 'dataset verify'
- Standalone 'ml dataset hash' command was redundant
- Users can use 'ml dataset verify <path>' to get hash
All tests pass.
