1 · ES&H Document Classes
A future operational condition never authorizes creating, issuing, signing or dating a document in the future.
Class A — Governing / Controlled Document
DocumentStatus = CURRENT_AND_APPLICABLE
Approved · current · effective · applicable to the activity · within revision validity · available to the user · traceable to authoritative source. An expired, superseded, withdrawn or non-applicable governing document cannot support readiness.

Class B — Daily / Shift Operational Record
Created on the actual date, for the actual shift, crew, location and activity
Signed / validated per the applicable requirement and temporally valid for the applicable work window. SHALL NOT be created with a future document date.

5 · Daily / Shift Record Validity (Class B)
Validated
DocumentCreationDate = ActualOperationalDate · Shift = ActualApplicableShift · Crew = ActualCrew · Location = ActualLocation · Activity = ActualActivity · ApplicableProcedureRevision = CURRENT · ApplicableRequirements = CURRENT
A record may reference a future operational condition only where
1. The governing procedure expressly permits it · 2. The condition belongs to a future operational interval · 3. The document itself was created and issued on the actual current date · 4. The validity window is explicitly recorded · 5. No future date is used as the document creation or signature date
6 · PETAR / Permit Temporal Rule
Rule
PETAR and equivalent permits are DAILY_SHIFT_OPERATIONAL_RECORDS unless the governing project requirement establishes another validity rule. Where the applicable requirement defines daily / shift / time-window / activity / location validity, the permit follows that requirement exactly. A permit issued now with a later operational validity window is CURRENT_DOCUMENT_WITH_FUTURE_OPERATIONAL_VALIDITY_WINDOW — not a future-dated document — and only where the governing requirement supports it.
Worked example
DocumentCreationTimestamp 2026-09-01T17:00 · OperationalValidityStart 2026-09-01T19:00 · OperationalValidityEnd 2026-09-02T07:00 → CURRENT_DOCUMENT_WITH_FUTURE_OPERATIONAL_VALIDITY_WINDOW (not a future-dated document).
7-8 · Fail-Closed Dispositions
No warning-only state. No automatic correction. No AI normalization. No timestamp rewriting.
INVALID_FUTURE_DATED_DOCUMENT
TemporalCompliance = FAIL · ComplianceDisposition = REJECTED · Workflow / Readiness / Authorization promotion = PROHIBITED · ReasonCode = FUTURE_DATED_DOCUMENT
INVALID_BACKDATED_RECORD
TemporalCompliance = FAIL · ComplianceDisposition = REJECTED · ReasonCode = BACKDATED_DOCUMENT. Governed late entry requires LateEntry = TRUE, preserved OriginalEventTimestamp, actual RecordCreationTimestamp, mandatory reason and authority where required. No original timestamp may be overwritten.
9 · OER-03 Temporal Correction
Withdrawn interpretation
"The document must have a future date" — WITHDRAWN as semantically invalid.
Corrected interpretation
The Owner decision is issued on the actual date/time. The prospective BEFORE measurement may have a later operational start condition where valid and authorized.
OwnerDecisionTimestamp
ACTUAL_TIMESTAMP
MeasurementEffectiveStart
OWNER_DEFINED_OPERATIONAL_START
DocumentDate
ACTUAL_DATE
FutureDocumentDate
PROHIBITED — NOT_USED
Prospective means
Measurement starts after valid methodological authorization and before the controlled demo intervention. It does NOT mean a future-dated document.
BC-09 remains OPEN_BLOCKING. This correction clarifies the temporal semantics only; it acquires no owner decision and closes no predicate.
