From 6271b521b45edfec1705821b16bd2d64d1497752 Mon Sep 17 00:00:00 2001 From: Steve Yegge Date: Sun, 26 Oct 2025 20:17:48 -0700 Subject: [PATCH] bd-162: Add database integrity checks with oracle review fixes - Added validatePreExport to prevent data loss - Added checkDuplicateIDs to detect corruption - Added checkOrphanedDeps to find orphaned dependencies (both sides) - Added validatePostImport to ensure imports don't lose data - CRITICAL FIX: Removed post-pull export that clobbered fresh JSONL - Conservative checks when JSONL is unreadable - Efficient COUNT(*) SQL path instead of loading all issues - Comprehensive test coverage including edge cases --- cmd/bd/daemon.go | 42 ++++- cmd/bd/export.go | 5 +- cmd/bd/integrity.go | 211 +++++++++++++++++++++++++ cmd/bd/integrity_test.go | 326 +++++++++++++++++++++++++++++++++++++++ cmd/bd/sync.go | 41 +++++ 5 files changed, 616 insertions(+), 9 deletions(-) create mode 100644 cmd/bd/integrity.go create mode 100644 cmd/bd/integrity_test.go diff --git a/cmd/bd/daemon.go b/cmd/bd/daemon.go index 5218ea3e..2301fe56 100644 --- a/cmd/bd/daemon.go +++ b/cmd/bd/daemon.go @@ -988,6 +988,25 @@ func createSyncFunc(ctx context.Context, store storage.Storage, autoCommit, auto log.log("Removed stale lock (%s), proceeding with sync", holder) } + // Integrity check: validate before export + if err := validatePreExport(syncCtx, store, jsonlPath);
