The bug report the agent sees

Concurrent PostgreSQL graph writes can produce inconsistent edge data. When multiple workers upsert the same relationship, including the endpoints in opposite order, duplicate directed rows may be created instead of one logical relationship being replaced. This can inflate degree counts and cause duplicate results. The same logical edge in different graph workspaces should remain independent, while reversed endpoint order within one workspace should be treated as the same relationship.

An edge upsert must preserve the existing replacement semantics: find the relationship without depending on endpoint order, remove any existing matching row, and create the resulting edge once. Empty property data must be accepted without generating an invalid query. Entity IDs—including Unicode text and values containing characters that resemble query syntax—must be stored and matched literally; user-provided graph names, endpoint IDs, and payloads must never alter the database query.

Concurrent or transient database failures must retain the established retry behavior. Transient database errors should be surfaced in the form recognized by the retry mechanism so the operation is retried, while ordinary errors such as `ValueError` should be reported promptly without repeated attempts. Edge-upsert execution must also continue to emit the established graph edge-upsert timing label.

The custom knowledge-graph insertion path must coordinate overlapping writes consistently with other graph-ingestion operations. Its synchronization scope must include every entity name and every relationship endpoint that the batch may write, using the workspace-specific coordination domain, so concurrent batches touching any common name do not race. A batch with no entities or relationships should perform no keyed-lock acquisition.

Serialising an edge upsert. Because the optional-match, delete and create sequence is not atomic, `upsert_edge` must run two statements on the same connection inside an explicit transaction: first a lock statement, then the cypher upsert. The lock statement uses `pg_advisory_xact_lock` over a key built from the graph name and the endpoint pair, passing them as positional parameters so no caller value is ever interpolated into the SQL. Its text must contain `$1::text || E'\x01' ||`, `LEAST($2::text, $3::text)` and `GREATEST($2::text, $3::text)`, must contain neither the graph name nor either endpoint id literally, and is called with the arguments in the order graph name, source id, target id. The key is therefore identical for reversed endpoints, so an upsert of A to B and one of B to A take the same lock, while the same pair in a different graph does not. The cypher statement itself must not contain `pg_advisory_xact_lock`, since AGE refuses to plan a join against a cypher call containing a create clause.

IMPORTANT: Work in the repository at /app and commit your changes when you are done. Your submission is the diff from the starting commit.

+"""
+Pin the business-layer keyed-lock contracts on the entity-mutation paths.
+
+`get_storage_keyed_lock(keys, namespace=...)` acquires one mutex per key in
+the given namespace, so identical key strings share the same mutex across
+callers. Locking `[entity_name]` is therefore already enough to mutually
+exclude any concurrent edge write that names the same entity in
+`sorted([src, tgt])` — no need to enumerate incident edges here.
+
+These tests pin:
+- `aedit_entity` locks {old, new} on rename, {entity_name} otherwise.
+- `adelete_by_entity` locks {entity_name}.
+- `ainsert_custom_kg` locks every entity name plus every relationship
+  endpoint that the batch will write, sharing the doc-ingest namespace.
+- An empty `ainsert_custom_kg` batch skips the lock entirely.

Verifies the fix for KeyError when entity names contain double quotes (PR #2872)
and the follow-up Option C refactor to parameterized Cypher queries.

The root cause: AGE returns the original un-escaped entity_id, but the edges_norm
dict was previously keyed with the normalized (escaped) ID, causing a KeyError on lookup.

The Option C fix: use $node_ids / $entity_id parameters instead of string interpolation,
eliminating the need for _normalize_node_id in these read paths entirely.

# Repository Guidelines

## Project Overview

LightRAG is a Retrieval-Augmented Generation (RAG) framework that uses graph-based knowledge representation for enhanced information retrieval. The system extracts entities and relationships from documents, builds a knowledge graph, and uses multiple retrieval modes (`local`, `global`, `hybrid`, `mix`, `naive`) for queries.

## Project Structure

Top-level directories:

- **lightrag/**: Core Python package — see *Module Layout* below.
- **lightrag_webui/**: React 19 + TypeScript client (Bun + Vite + Tailwind). UI components in `src/`.
15 more lines
- **scripts/**: `test.sh` (preferred test runner), `setup/` interactive environment wizard (use `make env-*` rather than calling `setup.sh` directly — see *Configuration > Setup Wizard Outputs*), and release tooling.
- **tests/** and root-level `test_*.py`: Pytest coverage. Working datasets stay in `inputs/`,

### Storage Configuration

Configure via environment variables or constructor params:
