Trust / Evidence Standards

See where the evidence came from — and what it means in context.

Talvrin Evidence Standards describe how source-linked research preserves provenance, timing, jurisdiction, version, rights/access state, evidence relationships, and the separation between source evidence and interpretation.

AI may assist research, but generated output does not become authoritative evidence. Coverage, availability and rights depend on released capabilities and governed sources.

Six Evidence Doctrine Principles

Six principles govern every evidence surface.

These principles apply across Research, Evidence and Monitoring — not only on this page.

Evidence before assertion

Important conclusions remain connected to the information supporting them.

Source before summary

A convenient explanation must not erase the underlying source.

Transparency before persuasion

Explain uncertainty rather than manufacture certainty.

Coverage before claims

Describe what is actually supported rather than theoretical capability.

Context before confidence

Dates, jurisdictions, versions and relationships can materially change meaning.

AI assistance, not AI authority

AI may accelerate research without becoming the evidence.

Source to Research View

Don't just show me the answer. Show me why.

Every displayed research conclusion preserves a navigable path back to evidence where the product supports that relationship. The chain never implies that every source is equally authoritative or equally complete.

The Evidence Object, One Contract

The minimum fields a public evidence object can expose.

Every field is conditional on registry support and publication approval. No field is invented to make an item look more complete than the governed source record allows.

evidence_id
Internal stable identifier; not necessarily public.
Internal
source_identity
Named organization, publisher, issuer or authority — never generic "web source" when known.
Required when known
source_class
Primary / official / licensed / institutional / other governed class.
Conditional
original_title
Human-readable original source title.
Where permitted
publication_time
Source publication time plus timezone where material.
Conditional
effective_reference_period
Period to which the evidence applies, where different from publication time.
Conditional
jurisdiction
Relevant jurisdiction or market context.
Conditional
version_state
Current / prior / superseded / corrected / unknown or governed equivalent.
Conditional
supersedes_ref
Link to prior or next version where governed and rights/retention allow.
Conditional
rights_access_state
Permitted / restricted / unavailable / governed equivalent.
Required for actions
evidence_relationship
Supports / contradicts / updates / contextualizes a defined research object.
Conditional
open_source_action
Deep link or governed viewer route, only when permitted and available.
Conditional
provenance_layer
Source / normalization / Talvrin analysis / AI-assisted / user note.
Required if mixed
change_state
New / updated / unchanged / superseded / materiality pending / unavailable.
Conditional
limitations
Human-readable limitation or unknown state.
Mandatory if material
last_reviewed
Governed review timestamp for Talvrin’s interpretation, not source publication time.
Conditional

No-score rule

The supplied Talvrin sources do not establish an evidence confidence score, source trust score, quality score or completeness score. Designers and engineers must not invent one. A future governed methodology would require its own approved definition, calibration and publication gate.

Classification, Not a Quality Score

Five registry-backed source classes.

Source class is descriptive provenance metadata. It does not imply that every "official", "licensed" or "institutional" source is complete, current, or superior in every context.

Published and Effective Are Different Questions

Time, version and jurisdiction stay visible when meaning changes.

Unknown or not-supplied context is kept explicit — it is never silently promoted to a confident state.

Publication time
Display source publication timestamp; include timezone where material.
Effective / reference period
Shown separately when the evidence applies to another date or period.
Reporting / economic period
Exposed when material to filings, economic data, fiscal data or policy.
Retrieval / ingestion time
Internal/conditional; public only where meaningful — never used to call a source "current."
Jurisdiction
Exposed when meaning depends on legal, economic or market context.
Last reviewed
Applies to Talvrin’s interpretation or standard review, not source publication.

Lineage Without Rewriting History

A superseded source stays traceable — it never silently disappears.

  • Where a source provides revision/version semantics, the evidence card or timeline exposes current vs. prior, superseded or corrected state.
  • A corrected or superseded source must not silently overwrite the research trail when retention and rights permit lineage to remain visible.
  • The research object records which version was used at the relevant time, so later reassessment can explain why a view changed.
  • If lineage cannot be established, the product shows an honest unknown/unavailable state rather than inferring one.
  • Version history is not a promise of indefinite retention; retention depends on approved product, rights and governance policy.

Transparency Does Not Override Rights

Evidence can be inspectable without ignoring data rights.

Rights/access state constrains what can be displayed, linked, quoted, cached, exported or made available to a user. Restricted content is never exposed beyond permitted use.

Permitted
Shows permitted metadata/content according to rights policy.
Opens the governed viewer or deep link if available.
Restricted
Shows only permitted metadata and a clear restricted state.
No unauthorized content exposure; only the approved next action is offered.
Unavailable
Explains the source/action is unavailable without pretending evidence never existed.
Disables or removes the broken action while retaining permitted context.
Unknown / unresolved
Does not assume access rights.
No public open action until resolved by rights governance.

Licensing, entitlement, permitted-use and redistribution principles are the dedicated subject of Data Rights →.

Evidence Relationships

Evidence can support a view without becoming the view.

Relationships stay neutral. None of them equal proof, recommendation or certainty.

Supports

The source provides evidence consistent with the research proposition or fact being examined.

Say "supports" rather than "proves" unless the proposition truly warrants stronger language.

Contradicts

The source conflicts with or weakens the proposition or assumption.

Keep visible and equally navigable — never suppressed because it is inconvenient.

Updates

The source changes or supersedes relevant evidence or context.

Connect to the change/version timeline where supported.

Five Layers, Never Blurred

Source, normalization, analysis, AI and user notes stay visibly distinct.

Every mixed-content surface keeps these layers persistently labeled rather than visually merged.

Source evidence
Highest evidence-source treatment; named source; metadata grouped.
Source identity + relevant time/context + rights/access + relationship where applicable.
Talvrin normalization
Neutral transformed-data treatment; labeled as normalized/structured by Talvrin.
Reference to underlying source(s) where supported.
Talvrin analysis
Interpretive treatment, clearly distinct from source.
Author/editor/process attribution where appropriate and governed.
AI-assisted interpretation
Persistent AI-assisted label plus source links where relevant.
Never source-authority styling; never guaranteed-fact wording.
User-created notes
Workspace/user-origin treatment.
User/workspace attribution according to product/privacy rules.

Uncertainty Stays Visible

Seven states — none of them quietly becomes certainty.

Unknown stays unknown; restricted never exposes content beyond permitted use; materiality is never assumed by default.

Unknown
States that the relevant fact or state is unknown or not established.
Never an ambiguous blank when the state is material.
Partial
Explains which part is available or limited.
A visible limitation label sits near the affected evidence.
Conflicting
States that evidence conflicts; avoids forced synthesis into certainty.
Shows both or all relevant evidence relationships.
Restricted
Explains the access limitation without disclosing restricted details.
No unauthorized open or export action.
Unavailable
Explains the source or action is unavailable.
Preserves permitted metadata and dependency context.
Materiality pending
States a change exists but materiality is unresolved.
Never styled as high-impact or material until governed.
Superseded
States that a newer version exists.
Maintains lineage/timeline where retention and rights allow.

Change Without Fake Materiality

A source update is not automatically a material change.

Source change is differentiated from market-price movement and from research materiality. Where monitoring is not live for a class or market, the limitation is shown instead of implying continuous monitoring.

Change ≠ materiality

A new item, revised document or restored availability is an evidence change — not automatically a material one.

Change carries context

Source identity, change type, time and affected research relationship accompany each event where available.

Unchanged is a scoped claim

Meaningful only when the comparison process and scope are defined — never implied as exhaustive monitoring.

Inspectable, Accessible, Honest About Limits

The source should never disappear behind the answer.

  • A descriptive deep link or governed viewer route is used — never a tiny icon as the only control.
  • If external, the user is told they are leaving Talvrin, without creating warning fatigue.
  • If access is restricted, the state and next permitted action are explained — never a broken or dead link.
  • Source-open events never leak sensitive query, entitlement, token or internal identifier data into analytics.
