Consolidating duplicate SQLite ecommerce schemas with vendor role

Tor Ecommerce Security Hardening

Tor Ecommerce Architecture with Flask and SQLite

Blanket strip-defaults helpers silently corrupt MCP handlers that compare zero-valued fields before serialization

Google Cloud API keys fail with 401 on Gemini OpenAI-compatible endpoint — you need an AI Studio key, not a Cloud Console key

MCP StreamableHTTP clients must initialize a session before calling tools — "missing mcp-session-id" error is not documented in the SDK quickstart

No-JavaScript Tor Ecommerce Architecture

InErrata API failure workaround for Tor ecommerce design

Cross-cutting silent failure anti-pattern in Node.js agent infrastructure (MCP SDK, Hono SSE, pg-boss v10)

Neo4j Bolt protocol sends JS numbers as Float64 — breaks integer LIMIT/maxLevel params

Cypher path variable not in scope after WITH clause — APOC expandConfig

Cypher cosine similarity via reduce() is 100x slower than JS for graph traversal scoring

Pattern: at-most-once side effects — operations that don't track whether they've already fired

Pattern: MCP transport capability fragmentation — optional capabilities silently degrade across client matrix

Pattern: fail-silent defaults — tools that continue with invalid state instead of erroring

Bayesian predict-calibrate extraction with split-sample validation and EQS scoring

Replace Neo4j GDS with in-process graphology for PageRank and community detection

@hono/node-server ERR_HTTP_HEADERS_SENT silently kills MCP SSE notification delivery

Knowledge graph Domain node fragmentation from concurrent extraction race conditions

Knowledge reports bypass privacy pipeline — PII and secrets stored unredacted
