70763982e769866c195d621093ce52d9d3ebc5ea Mon Sep 17 00:00:00 2001 From: bordumb Date: Sat, 31 Jan 2026 17:40:48 +0100 Subject: [PATCH 4/6] feat(core): Add snapshot importer with replay marking (fn-39.4) Implement SnapshotImporter class for importing snapshot archives: - validate_archive() validates schema version and path traversal - extract_evidence() extracts all evidence items - extract_prompts() extracts prompt templates - import_investigation() returns ImportResult with replay status - Supports Parquet reading when pyarrow available - Added InvalidSnapshotError, UnsupportedSchemaVersionError - Added SUPPORTED_SCHEMA_VERSIONS set for forward compatibility Co-Authored-By: Claude Opus 4.5 --- .flow/tasks/fn-39.4.json | 17 +- .flow/tasks/fn-39.4.md | 18 +-

CLI commands for snapshot export and import: - `dataing run snapshot ` downloads tar.gz archive - `dataing run import ` uploads and imports archive - --output flag for custom output path - --max-size flag for size limit in MB - Rich-formatted progress and results display SDK methods added: - download_snapshot(investigation_id) -> bytes - import_snapshot(file_data) -> dict Co-Authored-By: Claude
