root	9992b5f135	Database connector: PostgreSQL → Parquet import ... - POST /ingest/postgres/tables — list all tables in a database - POST /ingest/postgres/import — import table → Parquet → catalog → queryable - Auto type mapping: int2/4/8 → Int, float4/8 → Float64, bool → Boolean, text/varchar/jsonb/timestamp → Utf8 (safe default per ADR-010) - Auto PII detection + lineage on import - Empty password support for trust auth - Tested: imported lab_trials (40 rows, 10 cols) and threat_intel (20 rows, 30 cols) from local knowledge_base Postgres database — immediately queryable Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-27 20:14:16 -05:00
root	bb05c4412e	Phase 6: Ingest pipeline — CSV, JSON, PDF, text file support ... - ingestd crate: detect file type → parse → schema detection → Parquet → catalog - CSV: auto-detect column types (int, float, bool, string), handles $, %, commas Strips dollar signs from amounts, flexible row parsing, sanitized column names - JSON: array or newline-delimited, nested object flattening (a.b.c → a_b_c) - PDF: text extraction via lopdf, one row per page (source_file, page_number, text) - Text/SMS: line-based ingestion with line numbers - Dedup: SHA-256 content hash, re-ingest same file = no-op - Gateway: POST /ingest/file multipart upload, 256MB body limit - Schema detection per ADR-010: ambiguous types default to String - 12 unit tests passing (CSV parsing, JSON flattening, type inference, dedup) - Tested: messy CSV with missing data, dollar amounts, N/A values → queryable Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-27 08:07:31 -05:00
