…ction test model
Shared ModelOutputParser (fence strip + balanced extraction) for the live and HITL-resume paths; outcome recorded as llm:output:outcome:<taskId> and eddi.llm.output{outcome}. Adds the scripted FaultInjectingChatModel (test scope) and the resilience plan under planning/.
…and document eddi.llm.output
…uteWithRetry the only retry loop
Adds FailureClass/LlmFailure/LlmFailureClassifier (status + provider error body,
cause-chain aware); isRetryableError becomes a wrapper. HTTP 500 is now retried,
quota 429s are not. New retry fields honorRetryAfter / maxRetryAfterMs. Sync
provider clients are built with maxRetries(0). Cascade traces carry failureClass
and count eddi.llm.failure{class,model}.
…rror R6: responseValidation gains fallbackMessage (template), fallbackField and fallbackQuickReplies; fallback turns are flagged llm:fallback:<taskId> and left out of the model history. R7: task-level onError fallback absorbs a failed model phase (control flow excepted) and records llm:error:<taskId>.
…eddi.llm.failure The judge model, tool-response summariser and SummarizationService call models built with maxRetries(0) and had no retry loop. They now run through RetryConfiguration.executeWithDefaultRetry. Adds the eddi.llm.failure panel and the retry fields to the Manager's LLM task type.

…me warnings Agent-level turnDeadlineMs / turnDeadlineReserveMs and a per-request X-EDDI-Turn-Deadline-Ms header give each turn one budget. Model retries, cascade steps and HTTP calls (and their retries) spend from it, skip what cannot fit and never sleep past it. A cascade step's model request timeout is clamped to the step so the provider call ends with the step. Deploy-time warnings (never blocking) for contradictory timeouts, convertToObject with no fallback path and a static worst case above the deadline.
Check ContentFilteredException before its supertype, cap overflowing retry delays and parse them defensively, let body rate-limit wording decide only when the HTTP status is unknown, bound the judge model's retry policy, and drop an unused test parameter.

Recovery order: local repair, same-model corrective re-asks, then cascade escalation (reason invalid_output), then the fallback. Tool mode re-asks only the final model call. Adds the llm_retry SSE event, eddi.llm.recovery retry/escalate counters and a dashboard panel.

Review comments at @docs/monitoring/eddi-full-metrics-dashboard.json:
- Line 5239: Update the eddi_llm_circuit_total expression to use rate instead of
increase so its transitions per second are comparable to the skipped-turn rate
on the shared axis.
- Around line 4231-4235: Update the gridPos values for panels 174, 49, 177, 157,
178, 175, 179, and 176 so each pair occupies distinct, non-overlapping grid
cells in row 140. Preserve the panels’ existing dimensions and ensure the
revised positions remain within the dashboard grid.
Review comments at
@src/main/java/ai/labs/eddi/configs/shared/RetryConfiguration.java:
- Around line 397-400: Update callWithin’s InterruptedException handling to
cancel the future and restore the calling thread’s interrupt flag before
rethrowing. In executeWithRetry, handle InterruptedException before failure
classification by restoring the interrupt flag and throwing a
LifecycleInterruptedException using the existing constructor signature; do not
let it enter the generic retry/classification path.
Review comments at
@src/main/java/ai/labs/eddi/engine/internal/ConversationService.java:
- Line 1501: Add an onLlmRetry override to IdempotentStreamingHandler that
forwards the reason and attempt to its delegate, matching the forwarding
behavior of its other callbacks.
Review comments at
@src/main/java/ai/labs/eddi/engine/lifecycle/ConversationEventSink.java:
- Around line 102-104: Update the `onLlmRetry` reason documentation in
`ConversationEventSink` to include `schema_mismatch` among the documented
reasons, matching the label forwarded by `LlmTask` for
`FormatRetryRunner.Trigger.SCHEMA_MISMATCH`.
Review comments at
@src/main/java/ai/labs/eddi/engine/memory/ConversationLogGenerator.java:
- Line 136: Update ConversationLogGenerator’s fallback filtering to omit only
output attributable to the fallback task, preserving successful outputs from
other matching LLM tasks in the same step; apply the same output-level
distinction in ConversationHistoryBuilder’s summarized-window history at
src/main/java/ai/labs/eddi/engine/memory/ConversationLogGenerator.java lines
136-136 and
src/main/java/ai/labs/eddi/modules/llm/impl/ConversationHistoryBuilder.java
lines 427-427.
Review comments at
@src/main/java/ai/labs/eddi/modules/llm/impl/CascadingModelExecutor.java:
- Around line 357-362: Update the turn-deadline handling around
`remainingAfterReserveMs()` so that when the post-reserve budget is below 500
ms, the first cascade model call uses the remaining turn time from
`remainingMs()` instead. Preserve the existing minimum-duration selection and
pre-step checks that stop later steps when insufficient time remains.
Review comments at
@src/main/java/ai/labs/eddi/modules/llm/impl/ConversationHistoryBuilder.java:
- Line 417: Update the prompt-merging logic in ConversationHistoryBuilder so
applying a configured prompt replaces only the current input before merging it
with the earlier fallback question, rather than replacing the entire last
UserMessage. Preserve the earlier question in both fallback-turn and
non-skipping history paths.
Review comments at @src/main/java/ai/labs/eddi/modules/llm/impl/LlmTask.java:
- Around line 1014-1017: Update the RemainingBudget passed to FormatRetryRunner
in executePlain, tool-mode re-ask, and resume re-ask so each uses the turn
deadline’s remaining budget when a deadline is available, falling back to
UNBOUNDED only when it is absent. This ensures re-asks start only when the
remaining time meets the configured minimum.
Review comments at @ui/manager/src/components/editors/llm/types.ts:
- Around line 223-225: Update the response-validation selectors for onEmpty,
onTruncation, and onContentFilter to include the retry action, using
RetryableResponseValidationAction where needed. Keep onRefusal and
onStreamingTimeout on the existing RESPONSE_VALIDATION_ACTIONS list.

Recovery observability, HITL-resume parity, and the resilience guide
Items R11, R12 and R13 of
planning/llm-turn-resilience-plan.md.R11: observability
Resolved model names:
audit:model_name, the cascade trace, the resultmodel, the circuit-breaker key and theeddi.llm.failuretag now record the name a${vars:…}reference resolves to, not${vars:gemini-model}. An unresolvable reference keeps the configured text rather than failing the turn.One structured INFO line per recovery action (new
LlmRecoveryLog), emitted by the call site that performs it:LLM recovery conversationId=… agentId=… class=… action=repair|retry|escalate|circuit_skip|fallback outcome=… attempt=… durationMs=…It replaces the context-free "Re-asking" INFO line and the cascade's circuit-skip WARN. The cascade's per-escalation INFO line is now DEBUG. Failure WARN and ERROR lines are unchanged.
Metric gaps closed:
eddi.llm.recoverygainsaction=repair,action=circuit_skipandescalatefor every escalation reason;eddi.llm.failure{class,model}is now counted for single-model tasks too. A cascade still counts once per step, never twice, and the breaker's own refusal is not counted as a model failure.R12: resume (HITL) path parity
