Enhance ml info to query server when connected, falling back to local
manifests when offline. Unifies behavior with other commands like run,
exec, and cancel.
CLI changes:
- Add --local and --remote flags for explicit control
- Auto-detect connection state via mode.detect()
- queryRemoteRun(): Query server via WebSocket for run details
- queryLocalRun(): Read local run_manifest.json
- displayRunInfo(): Shared display logic for both sources
- Add connection status indicators (Remote: connecting.../connected)
WebSocket protocol:
- Add query_run_info opcode (0x28) to cli and server
- Add sendQueryRunInfo() method to ws/client.zig
- Protocol: [opcode:1][api_key_hash:16][run_id_len:1][run_id:var]
Server changes:
- Add handleQueryRunInfo() handler to ws/handler.go
- Returns run_id, job_name, user, timestamp, overall_sha, files_count
- Checks PermJobsRead permission
- Looks up run in experiment manager
Usage:
ml info abc123 # Auto: tries remote, falls back to local
ml info abc123 --local # Force local manifest lookup
ml info abc123 --remote # Force remote query (fails if offline)
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

- Users can use 'ml dataset verify <path>' to get hash
All tests pass.
