TA-14 Admissibility and Evidence Integrity

TA-14 is built on a single non-negotiable condition:

Execution must be grounded in admissible evidence.

Admissibility is not a property of data alone.
It is a condition achieved only when evidence meets strict requirements of continuity, origin, timing, and completeness at the exact moment of execution.

Without admissibility, execution is not permitted.

What Admissibility Means

Admissibility is the determination that evidence is sufficient, valid, and intact to support a specific action at commit-time.

It answers a precise question:

Can this action be allowed based on what is provably known, preserved, and continuous right now?

Admissibility is not:

• confidence

• probability

• model output

• inference

• explanation

• retrospective justification

Admissibility is proof.

The Conditions of Admissibility

For evidence to be admissible under TA-14, it must satisfy all of the following:

1. Continuity
The record must be complete across the required time window.
No gaps, breaks, or silent loss of data are permitted.

2. Origin Integrity
The source of the evidence must be known, verifiable, and unaltered.
Evidence without traceable origin is not admissible.

3. Time Integrity
The evidence must be accurately time-sequenced and resistant to manipulation.
Order and timing must reflect reality, not reconstruction.

4. Non-Reconstruction
Evidence must not be recreated, inferred, or backfilled to fill missing states.
If reality was not captured, it cannot be manufactured.

5. Scope Completeness
The evidence must cover the full context required for the specific action.
Partial context is insufficient for admissibility.

If any one of these conditions fails, admissibility fails.

Evidence vs Data

TA-14 distinguishes between data and evidence.

Data may:

• be stored

• be processed

• be transformed

• be aggregated

• be overwritten

Evidence must:

• be preserved as it occurred

• remain append-only

• maintain its sequence

• retain its origin

• expose its gaps

Data can inform decisions.

Only evidence can authorize execution.

Append-Only Evidence

TA-14 requires that evidence exist within an append-only structure.

This means:

• new information is added, not overwritten

• prior states are preserved

• changes are recorded as new entries

• history is never rewritten

Append-only structure ensures that:

• the past cannot be altered

• continuity can be verified

• admissibility can be evaluated against a true record

If evidence can be modified or erased, it cannot be trusted at the moment of execution.

Continuity as a First-Class Requirement

Continuity is not a secondary concern.

It is foundational.

A perfectly accurate data point is not admissible if it exists within a broken timeline.

TA-14 does not allow systems to:

• assume continuity

• interpolate missing segments

• infer conditions between known states

• treat averages as replacements for sequences

If continuity breaks, admissibility fails.

This creates a strict condition:

The system must know what happened—not approximate it.

Time-Bounded Evidence

Admissibility is always evaluated within a defined time boundary.

Evidence must be:

• current within acceptable latency

• relevant to the moment of execution

• not stale beyond defined thresholds

Old data, even if accurate, may not be admissible.

Admissibility is not just about correctness.

It is about temporal validity.

Action-Specific Evidence Requirements

Admissibility is not universal.

It is specific to the action being taken.

Different actions require different evidence.

This is formalized through the concept of the Minimum Admissibility Unit (MAU).

Each action defines:

• what evidence is required

• how far back continuity must extend

• what sources must be included

• what conditions must be satisfied

A system must verify that the correct MAU is present and admissible before execution.

Degraded Evidence States

TA-14 explicitly recognizes degraded states.

Evidence may be:

• incomplete

• delayed

• partially corrupted

• missing segments

• uncertain in origin

When this occurs, the system must not silently compensate.

It must:

• block execution

• or escalate for intervention

Degraded evidence is not a warning condition.

It is a governing condition.

Admissibility vs Explanation

A system may explain itself perfectly and still fail admissibility.

Explanation describes reasoning.

Admissibility validates authority.

These are not interchangeable.

TA-14 does not accept:

• “the model believed it was correct”

• “the system explained its decision”

• “the output was consistent”

as substitutes for admissible evidence.

The system must prove that the conditions required for action existed.

Admissibility at Commit-Time

Admissibility must be evaluated at the exact moment of execution.

Not before.

Not after.

Not cached indefinitely.

At commit-time, the system must:

• validate continuity

• confirm origin

• verify timing

• ensure completeness

• bind evidence to action

If the state changes between evaluation and execution, admissibility must be re-evaluated.

Execution cannot rely on outdated proof.

Why Evidence Integrity Matters

Without evidence integrity:

• systems act on assumptions

• records become narratives instead of truth

• audits become reconstruction exercises

• accountability becomes ambiguous

• harm becomes explainable but not preventable

TA-14 prevents this by requiring that:

execution authority is inseparable from evidence integrity.

What Fails Without Admissibility

Without admissibility:

• actions may be technically correct but unjustified

• systems may behave consistently but without authority

• outcomes may appear valid but lack evidentiary grounding

• organizations may pass audits while failing governance

TA-14 rejects these conditions.

Execution without admissible evidence is not governed execution.

Summary

Admissibility under TA-14 requires:

• continuous, append-only evidence

• verified origin

• intact time sequence

• non-reconstructed reality

• action-specific completeness

• commit-time validation

If these conditions are met, execution may proceed.

If they are not, execution must not occur.

TA-14 does not allow systems to act on what is likely.

It requires systems to act only on what is provably true at the moment of consequence.

That is evidence integrity.

That is admissibility.

That is the foundation of execution governance.
