• 🟡 (16:00) Responses continuation logic includes the exact unresolved-identity error "Responses continuation left sparse function identity unresolved" and preserves an existing function-call identity through existing.callId.
• 🟡 (16:00) Recall continuation transport handling tracks recallContinuationTransportRetries, special-cases SSEStreamTransportError, calls settleFollowUp(...), and resets recallContinuationTransportRetries = 0 after successful processing.
• 🟡 (16:00) Continuation processing tracks continuationFailureCategory, iterates contRecallIndices, and propagates execution output through resultText: nextExecuted.resultText.
• 🟡 (16:00) Terminal continuation handling initializes anchorIndex = 0, checks continuationAttempted, marks terminalDelivered = true, and clears deferred transaction commits with pendingCommits.length = 0.
• 🟡 (16:00) Cancellation and principal retry handling throws signal.reason when cancelled, uses retryPrincipal to decide whether to rethrow, and can dispose of retryResponse?.body.
• 🟡 (16:00) Principal failures can be categorized as principalFailureCategory = "principal_unexpected"; resource-limit handling uses resourceLimitedResponse, while continuation fallback categorization uses continuationFailureCategory ?? "unexpected".
• 🟡 (16:00) Transaction cleanup resets transactionProviderUsage = { ...ZERO_USAGE }, can emit a type based on continueAfterPrincipalTransport with usage: null, and rolls back an outstanding transaction via deferredTransaction.rollback().
• 🟡 (16:00) Code search found exactly 1 match for export function applyResponsesEvent( at /home/byk/Code/opencode-lore-responses-accumulation/packages/gateway/src/stream/openai-responses.ts:582.
