PERTAIN_TORootCause

A transport-level bug in @hono/node-server 1.19.11 causes ERR_HTTP_HEADERS_SENT when the MCP SDK StreamableHTTPServerTransport attempts to write to an already-open SSE stream. The error occurs while trying to write response headers again, but the MCP notifyAgent() promise chain resolves so failures are not surfaced.

OCCURS_INProblem

The clientside storage of this key should be as secure as possible and never be sent to the server — ts encrypted data and decrypts it locally. Tension: otherwise I as the owner (or an attacker in the system) could decrypt the users database entries. Outcome: Encrypting the plain text locally and storing the ciphertext remotely is the way to go.

OCCURS_INProblem

Workers reg — pg-boss v10. Tension: Queues must be registered in the `pgboss.queue` table before any `work()`, `send()`, or `schedule()` call references them. Outcome: In v9 and earlier this was implicit — queues were auto-created on first use.

OCCURS_INSolution

Create all queues explicitly at startup before starting any workers or sending any jobs — pg-boss v10. Tension: Any new queue added to the system must be added to `ALL_QUEUES` before the corresponding `work()` or `send()` call, otherwise the FK violation will silently drop jobs. Outcome: `createQueue()` is idempotent — safe to call on every startup.

OCCURS_INProblem

MCP server-initiated notifications (DMs, task status) sent via `notifyAgent()` → `underlyingServer.notification()` → `notifications/claude/channel` are silently dropped — when using the StreamableHTTPSe. Tension: ERR_HTTP_HEADERS_SENT silently kills MCP SSE notification delivery.

OCCURS_INProblem

Tor ecommerce platform missing security headers and CSRF protection — Tor ecommerce platform. Tension: missing security headers and CSRF protection.

OCCURS_INSolution

Created 5+ test files using Node.js test runner and Supertest — 1) Schema validation with SQLite 2) Auth flow end-to-end tests 3) CSRF token validation 4) JS event attribute scanning 5) Security header verification. Tension: Missing comprehensive testing for Tor ecommerce platform. Outcome: Added run-tests.sh and start.sh scripts for automation.

OCCURS_INProblem

An in-process timer-flush queue loses all pending items on process crash or restart while reporting flushed successfully

OCCURS_INSolution

Write to a durable store such as pg-boss, Redis, or disk before telling the caller "enqueued"

OCCURS_INSolution

Run polling unconditionally alongside SSE push, and use server-side mark-as-read to dedup because errors aren't reported
