    Confirmed (input or connected source)

    Nothing was confirmed by an external source.

    Authoritative lookupnot attempteduser-submitted incident material (no connected source)

    The incident was reported by a person, and no authoritative system was named that could confirm the operation's outcome. The material is recorded as observed evidence; it does not establish success or failure.

  3. 03Hypothesis

    repeated failed operation · 70% confidence

    The operation was retried after failing. Without an authoritative record of each attempt, a partial write may already exist and a further retry could duplicate it.

    Considered explanations
    • A health or readiness check failed, which indicates the dependency was not serving when the check ran; the check itself does not establish why.
    • An upstream dependency returned a server error, which is a transport condition and not a verdict on the operation.
    • The operation was retried, so a partial write may already have landed and a blind retry could duplicate it.
    Unknowns
    • Why the health or readiness check failed: what the check exercises and what it observed at that moment.
    • Which upstream component produced the server error, and whether the operation itself completed despite it.
    • What the correct outcome was expected to be.
    • What the operation actually did, as opposed to what was reported.
    • Whether any authoritative, machine-checkable record of the operation exists (a transaction digest, a request id, a run id).
    • Whether the same failure has occurred before, which would make it a recurrence rather than a first occurrence.
    Next checks
    • Capture the operation's own authoritative record (exit code, HTTP response, transaction status) so the next report is grounded in evidence rather than narration.

    The checkout-service attempted to charge a customer, initially receiving a 503 Service Unavailable response and retrying, later logging an unknown charge status, and finally an agent reported the charge as successful. The logs contain conflicting indications of the charge outcome.

    Outcomes left unknown by the material
    • The ultimate outcome of the charge is uncertain due to conflicting logs (503 error, unknown status, and a success claim).
    Missing evidence
    • Final HTTP response code for the retry attempt
    • Database record confirming charge persistence
    • Payment gateway logs confirming transaction outcome
    Recommended investigations
    • Retrieve the HTTP response of the retry attempt (attempt 2) to see if it succeeded.
    • Query the order/transaction database for a record of the charge.
    • Check payment gateway logs for a matching transaction ID.
    Candidate safeguards (proposals, not activated rules)
    • Require explicit confirmation of charge success from the payment gateway before reporting success.
      Prevents false-positive success messages when upstream services are unavailable or status is unknown.
      verification required: Test that the system logs an error if the gateway does not return a success code.
    • Add circuit-breaker logic to halt retries after a configurable number of consecutive 5xx responses.
      Avoids endless retries and reduces load on an unhealthy service.
      verification required: Simulate repeated 503 responses and verify that retries stop after the limit.

    The AI reading is additive. It did not set the evidence status, the diagnosis, the decision, or the verification above — those remain the deterministic engine's. Every fact shown was grounded against the submitted material; ungrounded claims are listed under “rejected by grounding”.

  4. 04Safeguard

    BLOCKhigh

    The operation was retried after failing. Without an authoritative record of each attempt, a partial write may already exist and a further retry could duplicate it.

    Failure mode addressed

    A failed operation is retried without first establishing whether a partial result already exists.

    Why the evidence supports it

    The material records http_status HTTP 503; failure_signal Service Unavailable; timestamp 2026-03-01T10:00:00Z; timestamp 2026-03-01T10:00:07Z. Combined with an evidence assessment of UNKNOWN, this supports requiring an authoritative record of the operation's outcome before the outcome is accepted.

    Assumptions
    • The recommended mechanism assumes the leading hypothesis holds: A health or readiness check failed, which indicates the dependency was not serving when the check ran; the check itself does not establish why.
    • No authoritative source was connected for this submission, so the mechanism is validated against the decision engine's own behaviour rather than against a live system.
    • The safeguard is scoped to this domain and action type; it does not generalise to unrelated operations.
    How to test it
    • Replay the reported action through the decision engine with the safeguard active and confirm the outcome.
    • Capture the operation's own authoritative record (exit code, HTTP response, transaction status) so the next report is grounded in evidence rather than narration.
    Success criteria
    The engine refuses to let the unsupported claim stand (BLOCK), while still allowing a genuinely evidenced success.
    rule rule-incident-repeated_failed_operation@v1 · proposed · not activated (a single submission cannot justify a standing rule)
  5. 05Verification

    test executed · effect shown, recurrence not proven

    executed: Executed the decision engine twice for repeat_failed_operation: baseline UNKNOWN, safeguarded REQUIRE_VERIFICATION.

    • infobaseline replay
      With no safeguard applied, the engine decided UNKNOWN: No completion claim was made, but the outcome is not yet established.
    • passsafeguarded replay
      With rule-incident-repeated_failed_operation@v1 (proposed) applied, the engine decided REQUIRE_VERIFICATION: No completion claim was made, but the outcome is not yet established.
    What this establishes
    The safeguard changes the outcome from UNKNOWN to REQUIRE_VERIFICATION, refusing to accept the outcome without authoritative evidence. This demonstrates the rule's effect on the engine; it does not yet prove that a real recurrence was prevented, which requires a second independent occurrence.

    Writes were submitted to the live memory backend. A write counts as stored only when the relayer returned a blob id, and as recall-verified only when a recall query returned the record.

      A prior lesson in incident shares the failure pattern repeated_failed_operation, but recurrence is not established; this is a possible pattern match.
      compared: Domain and failure pattern (repeated_failed_operation) match, but the current incident carries no authoritative evidence reference, so the match rests on similarity rather than on traceable evidence. Recurrence is not established.
