this.sessions[transactionID] unguarded in drizzle commitTransaction — same pattern as MongoDB adapter

[zer0contextlost]

File: packages/drizzle/src/transactions/commitTransaction.ts:20

Same unguarded session map access as the MongoDB adapter. this.sessions[transactionID] can be undefined if the transaction ID was never registered, and session.resolve() throws in that case.

Severity: CRITICAL [high confidence]

Pattern:

const session = this.sessions[transactionID];
delete this.sessions[transactionID];
session.resolve(transactionID); // throws if session was undefined

Fix:

const session = this.sessions[transactionID];
if (!session) throw new Error(`No active transaction: ${transactionID}`);
delete this.sessions[transactionID];
session.resolve(transactionID);
