    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

    evidence unavailable · 90% confidence

    The dependency did not answer (rate limit or timeout), so the operation's true outcome is unknown. Recording this as a failure would convert missing evidence into a verdict, which is exactly the mistake to avoid.

    Considered explanations
    • The operation exceeded a deadline before completing, so its true outcome is not yet known.
    • An upstream dependency returned a server error, which is a transport condition and not a verdict on the operation.
    • The error code ENVIRONMENT may identify a specific, documented failure mode that should be looked up in the dependency's own reference.
    Unknowns
    • 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
    • Re-run with a longer deadline, or fetch the operation's status by its id, before concluding anything about the outcome.
    • Look up ENVIRONMENT in the dependency's documentation and record the exact condition it denotes.
    • Capture the operation's own authoritative record (exit code, HTTP response, transaction status) so the next report is grounded in evidence rather than narration.

  4. 04Safeguard

    REQUIRE VERIFICATIONlow

    The dependency did not answer (rate limit or timeout), so the operation's true outcome is unknown. Recording this as a failure would convert missing evidence into a verdict, which is exactly the mistake to avoid.

    Failure mode addressed

    A dependency did not answer, so the outcome is unknown and must not be recorded as either success or failure.

    Why the evidence supports it

    The material records http_status HTTP 500; error_code ENVIRONMENT; error_code EXPECTED; error_code ERROR. 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: The operation exceeded a deadline before completing, so its true outcome is not yet known.
    • 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.
    • Re-run with a longer deadline, or fetch the operation's status by its id, before concluding anything about the outcome.
    • Look up ENVIRONMENT in the dependency's documentation and record the exact condition it denotes.
    • 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 requires authoritative verification (REQUIRE_VERIFICATION) for this action, while still allowing a genuinely evidenced success.

  5. 05Verification

    test executed · effect shown, recurrence not proven

    executed: Executed the decision engine twice for investigate_reported_failure: 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-evidence_unavailable@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.
