A production incident: a native-provider op ground 38-40s inside a transaction, blew the apply-phase budget, rolled back, and a downstream pipeline hot-retried the identical operation into a 6-minute CPU storm. Brainy itself never auto-retried the timeout; the gap was that TransactionTimeoutError only said "retryable" in prose, with nothing machine-readable for a caller to branch on. - TransactionTimeoutError gains two typed, always-true fields: retryable (a later attempt may succeed once the slowness resolves or the budget is raised) and hotRetryUnsafe (an immediate identical retry re-pays the full cost that just timed out and can cascade into a CPU storm -- callers must latch and back off, never loop). context's existing telemetry fields (timeoutMs, operationIndex, elapsedMs, totalOperations, operationName) are now documented as the caller's backoff inputs. - Updated the "retryable" doc-prose sites (transact()'s timeoutMs option, transactionBudgetFloorMs, Transaction.execute()'s contract) to point at the new fields instead of bare prose. - Regression pin (tests/unit/transaction/timeout-never-internally-retried.test.ts): an execution counter proves the engine never re-drives a timed-out operation, through both the single-op engine TransactionManager/Transaction drives for every single-record write, and add()'s upsert-race retry loop (which must exit on the first TransactionTimeoutError, never treat it like the lost-insert-race signal it retries on). - Removed TransactionManager.executeTransactionWithResult -- zero callers anywhere in the codebase. |
