From 5c57f027d8a6c4706ccc37a4436e84f1157fcc0e Mon Sep 17 00:00:00 2001 From: Jaixii Date: Fri, 7 Aug 2026 23:09:30 -0400 Subject: [PATCH 01/68] feat(core): pro-feature hardening, release-readiness cleanup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Store/Schema: - Transaction rollback safety on Windows (commits_deferred flag) - Skip redundant index.upsert when index shares store vector table - Embedding-space contract validation and direct SQL matrix path - Restore orphaned Store methods (prompt_eligibility_counts, embedding_space_health, context_savings_grouped, add_sync_bytes, get_sync_stats) and harden _logical_digest for sqlite-vec - Dashboard startup self-check for orphaned Store methods - v11 handoff column migration for sessions table Release readiness: - Strip dead TEAM scope surface (Scope.TEAM, MemoryRecord.team_id, SearchFilter.team_id/caller_id) per AGENTS.md §0 - Remove team_id column from memories table (team_members retained) - Remove conflict_aware profile (zero callers/tests/docs) - Add format/group_by params to MemoryService.context_savings() Other: - watch_repo key name, LLM fallback chain cost tracking - context_savings_grouped SELECT columns - Sync robustness, response budgets, docs sync --- engraphis/core/consolidate.py | 11 +- engraphis/core/context.py | 55 +++++++ engraphis/core/interfaces.py | 2 + engraphis/core/query_planner.py | 18 ++- engraphis/core/schema.py | 34 +++- engraphis/core/store.py | 130 +++++++++++++++ engraphis/core/sync.py | 22 ++- engraphis/llm/client.py | 218 +++++++++++++++++++++++++ engraphis/service.py | 273 +++++++++++++++++++++++++++++++- 9 files changed, 752 insertions(+), 11 deletions(-) diff --git a/engraphis/core/consolidate.py b/engraphis/core/consolidate.py index c9a9569a..69f125cf 100644 --- a/engraphis/core/consolidate.py +++ b/engraphis/core/consolidate.py @@ -777,7 +777,8 @@ def consolidate(engine, *, workspace_id: str, repo_id: Optional[str] = None, profiles: bool = False, min_mentions: int = MIN_PROFILE_MENTIONS, infer: bool = False, structured: bool = False, supersede_sources: bool = False, llm: Any = None, - now: Optional[float] = None) -> dict: + now: Optional[float] = None, + consolidation_level: str = "flat") -> dict: """Run one consolidation sweep over a workspace (optionally one repo).

The staged path shares the same backfill helpers. - Tests: streamed-oversize 413 regression; existing declared-oversize, health, and migration suites pass.
