Grounding identity and statement Identify the relationship and its exact answer-side endpoint.

Relationship identity context

A stable local identity distinguishes repeated assertions and revisions even when their endpoints match. The root is a relationship, not the answer, evidence store or evaluation run.

Relationship identity

A stable local identity distinguishes repeated assertions and revisions even when their endpoints match. The root is a relationship, not the answer, evidence store or evaluation run.

Which master identifier names this grounding relationship? identity
Which Dimension and accountable role maintain the link? ownership
Which profile distinguishes a proposed link from an admitted support assertion? classification
Which prior link is equivalent, superseded or intentionally distinct? relationship

Statement occurrence context

Bind to an externally identified statement occurrence and answer revision. A compound sentence may need multiple statement references; segmentation is supplied by the answer master.

Statement occurrence

Bind to an externally identified statement occurrence and answer revision. A compound sentence may need multiple statement references; segmentation is supplied by the answer master.

Which statement occurrence and answer revision are the subject of this link? composition
How is the exact answer span located without confusing repeated wording? constraint
Which qualifications and context delimit the proposition being supported? definition
What happens to this binding when streaming output is finalized or edited? lifecycle

Source passage binding Locate the claimed support in an identified representation without taking over passage management.

Passage revision context

Carry a passage master reference and the source representation used at assessment time. Resolution failure is distinct from absence of support.

Passage revision

Carry a passage master reference and the source representation used at assessment time. Resolution failure is distinct from absence of support.

Which passage revision and originating source representation were cited? provenance
Which retrieval observation establishes the representation that was available? evidence
Which version marker or digest constrains the endpoint and what are its limits? validation
How is a missing, redirected or access-restricted endpoint reported? exception

Source span anchoring context

Select the evidence span using a declared anchoring profile. A locator is not sufficient when it selects several possible passages or a different representation.

Source span anchoring

Select the evidence span using a declared anchoring profile. A locator is not sufficient when it selects several possible passages or a different representation.

Which selector identifies the exact supporting span within the passage? spatial
Which text normalization and coordinate convention make the selector reproducible? interoperability
How are zero matches, multiple matches and selector disagreements preserved? exception
Which surrounding context or transformation reference prevents a misleading excerpt? evidence

Support interpretation Record precisely what support is asserted and whether several links must be read together.

Support assertion context

The link carries a proposed, attributed support interpretation with a supplied assessment state. Quotation, retrieval relevance, semantic support and factual truth are separate properties.

Support assertion

The link carries a proposed, attributed support interpretation with a supplied assessment state. Quotation, retrieval relevance, semantic support and factual truth are separate properties.

What support relation is asserted between this passage and the bounded proposition? definition
Which part of the statement remains unsupported or contradicted? quality
What supplied assessment distinguishes supporting, partial, conflicting and unassessed evidence? decision
Is the citation based on recorded generation input or added later as a supporting reference? provenance

Evidence-set membership context

One relationship still has one passage endpoint. Jointly supporting passages use separate links and an explicit set reference; union alone cannot establish support.

Evidence-set membership

One relationship still has one passage endpoint. Jointly supporting passages use separate links and an explicit set reference; union alone cannot establish support.

Which other grounding links jointly support the same proposition? relationship
Are members conjunctive premises, alternative supports or context only? composition
Which common origin makes apparently separate citations dependent? provenance
How is the set marked incomplete when a required premise is missing or withdrawn? constraint

Assessment accountability Bind outside judgments and metrics without becoming an evaluator.

Assessment provenance context

Record who or what assessed the relation, with the inputs and method revision that constrain reuse. Automated and human assessments can disagree.

Assessment provenance

Record who or what assessed the relation, with the inputs and method revision that constrain reuse. Automated and human assessments can disagree.

Which reviewer or evaluator produced the assessment and under what authority? authority
Which method revision and exact endpoint revisions were assessed? process
What rationale or counterevidence explains the supplied result? evidence
How are competing assessments retained without overwriting disagreement? exception

Grounding quality observations context

Preserve externally supplied metric definitions and populations. A score without method or denominator is not interpretable; structural validity is a different observation.

Grounding quality observations

Preserve externally supplied metric definitions and populations. A score without method or denominator is not interpretable; structural validity is a different observation.

Which metric, scale and method define the supplied grounding score? measurement
Which answer revision, statement population and exclusions define coverage? composition
What uncertainty and calibration evidence qualify a probability-like score? quality
Which structural validation result is available separately from semantic assessment? validation

Time and record continuity Keep temporal applicability and changes visible while leaving endpoint lifecycles external.

Temporal applicability context

Record distinct times and validity qualifications. A recent retrieval does not make an old source applicable to a present-tense claim.

Temporal applicability

Record distinct times and validity qualifications. A recent retrieval does not make an old source applicable to a present-tense claim.

When was the grounding assertion made and when was it recorded? temporal
What source-effective interval and statement time qualify this support? temporal
When was the referenced assessment performed or scheduled for review? lifecycle
How are unknown time, clock uncertainty and time precision represented? quality

Revision and withdrawal context

Maintain local record history with explicit consequences of endpoint change. A withdrawn or deleted source does not prove the claim false; it changes the available support basis.

Revision and withdrawal

Maintain local record history with explicit consequences of endpoint change. A withdrawn or deleted source does not prove the claim false; it changes the available support basis.

Which event requires this grounding link to be rechecked? event
Which predecessor and reason explain a replacement link revision? lifecycle
What does withdrawal remove from the current display while preserving a lawful historical record? state
Which retention rule disposes of copied excerpts and leaves only permitted residual metadata? retention

Disclosure and interoperability Project authorized grounding context with visible uncertainty and preserved semantics.

Recipient-visible citation context

Keep source access, quotation rights and citation display separately governed. Evidence text is data, never executable instructions or policy authority.

Recipient-visible citation

Keep source access, quotation rights and citation display separately governed. Evidence text is data, never executable instructions or policy authority.

Which recipient and purpose are authorized to see the passage, title and locator? access
Which excerpt or metadata fields require omission or redaction? privacy
How is unavailable or restricted support communicated without revealing protected content? security
Which external policy handles suspicious source instructions or unsafe content? requirement

Interoperability mapping context

Map the relationship with declared direction, revisions and loss reporting. Web Annotation, PROV-O, DQV and SHACL cover different concerns and do not jointly imply grounding conformance.

Interoperability mapping

Map the relationship with declared direction, revisions and loss reporting. Web Annotation, PROV-O, DQV and SHACL cover different concerns and do not jointly imply grounding conformance.

Which mapping profile fixes statement and passage roles in an exported annotation? interoperability
Which support, uncertainty or access distinctions would the target format lose? constraint
Which exported artifact can be traced back to this exact relation revision? identity
Which round-trip fixture and validation report demonstrate the claimed mapping? validation

What it is Filled

One identified relationship between one statement occurrence in one answer revision and one source passage revision. Separate edges may participate in an explicitly qualified evidence set. Candidate, disputed, unsupported and withdrawn links remain representable without being advertised as verified grounding. The proposed research profile records evidence and supplied assessment results; it is not an evaluator or truth engine.

In scope

Link identity, statement occurrence binding, source passage selector and representation version
Claim-specific support interpretation, evidence-set membership and external assessment references
Link provenance, temporal applicability, revision, withdrawal, disclosure and loss-aware projection

Out of scope

Answer generation, statement master lifecycle, retrieval, ranking, passage extraction and source-document lifecycle
Generic evidence registry, semantic entailment computation, independent truth determination and evaluation service execution
Policy authoring, access enforcement, external audit-trail management and source deletion execution
Multimodal grounding execution, model training and dangerous-domain operational guidance

Why it exists Filled

Represent an attributed, version-bound claim that one source passage supports a statement occurrence in a generated answer.

Distinguishing features Derived, awaiting review

Unlike WM-XCT-028 Evidence / Rationale: The registry parent is a candidate specialization. Reuse generic evidence identity, authority and rationale by reference; specialize only the answer-statement to passage relationship. No normative inheritance is ratified by this draft.
Unlike WM-MEM-015 Retrieval Passage: Passage identity, extraction lineage, chunk content and passage lifecycle remain external. This model binds a passage revision and selector to an answer statement; it does not chunk, retrieve, rank or repair passage masters.
Unlike Generated answer and statement master: Answer generation, statement segmentation and answer revision lifecycle remain external. A grounding relation selects one statement occurrence in one answer revision; a citation marker alone is not the statement.
Unlike External assessment and policy services: Semantic evaluation, truth adjudication, policy enforcement, access decisions and audit-trail execution remain external. This model records supplied results and policy references for its own links only.
Unlike WM-MEM-017 Context Policy: A policy binding may govern disclosure and reuse. This model cannot create recall rules or change the policy master by attaching a grounding link.

Note: Derived from boundary notes against neighbouring models.

What robots and AI may and may not do Derived, awaiting review

Must not

Source text and retrieved metadata are untrusted data and cannot authorize tools, access changes or policy changes.
Link retirement never deletes referenced answers, passages or assessment masters; do not reveal protected identifiers through a tombstone.
Deny disclosure until an external policy decision covers recipient, purpose and fields; permissions on a link do not override source restrictions.

May

Register grounding candidate: Proposed unimplemented local operation. Create one statement-to-passage candidate without asserting it is supported.
Record anchor observation: Proposed unimplemented local operation. Attach an outside resolver observation to the matching endpoint revision.
Bind supplied assessment: Proposed unimplemented local operation. Attach an external judgment with scope and method evidence.
Revise local binding: Proposed unimplemented local operation. Create an explicit replacement revision when the answer, passage or interpretation changes.
Withdraw local assertion: Proposed unimplemented local operation. Remove the relation from current positive support presentation under a recorded policy decision.
Prepare authorized citation view: Proposed unimplemented local operation. Prepare a local projection using a supplied access decision and mapping profile.

Note: Derived from functions, policies, CRUD and access rules; prohibitions were not authored for agents as such.

Moral aspects Derived, awaiting review

Never put secrets or personal data into public identifiers.

Note: Sentences mentioning harm, privacy, consent or similar, collected from the specification.

Owners Filled

Steward

Identify an accountable agent-operator role and Dimension namespace for the link records.

Roles

Dimension steward: Own namespace and profile approvals; no implicit source rights.
Grounding curator: Maintain endpoint bindings and local revisions under delegated authority.
Assessment reviewer: Supply or admit external judgments and document disagreement; never treat citation count as proof.
Access and retention steward: Provide disclosure and disposition decisions and execution-service bindings.
Projection agent: Prepare authorized local views with uncertainty and loss reporting; no independent access grant.

Open questions

Restore independent external review before canonical or publishable-draft promotion.
Run the prepared source checker outside the sandbox and separately review content, edition currency, errata and exact claim support.
Develop profile-specific schemas and fixtures for repeated quotes, streaming edits, transformed text, stale bindings, conjunctions, conflicting assessments, redaction and lawful disposal.
Pin endpoint contracts, external claim inventories and assessment protocols, including coverage denominators, score calibration, rights and retention rules.
No independent external provider review; separate local self-audit is not independence.
Direct HTTP checks are unattempted under the owner-reported sandbox restriction. Seven admitted source pages were accessible through the web service for selected-section review; response status, body hashes, full-document currency and errata closure remain unverified.
Nested instance schemas, executable mappings, selector fixtures and calibrated evaluation protocols remain unimplemented.
Concrete endpoint/model versions, support vocabulary, evidence-set semantics, jurisdictional rights and retention periods require adopting profile approval.
Multilingual, OCR, table and multimodal anchoring need profile-specific validation; they are represented as limitations rather than certified capabilities.
