Contract Implementation Matrix

Contract 009 implementation update (2026-08-04)

The bounded implementation is verified with declared fixture profile, registry, schema, configuration, rule, identity, replay, and persistence dependencies. SemanticReconciliationInput remains the Contract 009 semantic entry point, and SemanticNormalizationInput is the sole Contract 010 entry point. Contracts 009 and 010 are implemented only within their declared fixture surfaces; later acts remain outside this slice.

Review date: 2026-08-04
Scope: Contracts 000–015 only. This is an implementation-extraction matrix, not an implementation plan, an IMP specification, a canonization decision, or authorization to write runtime code.

Reading rules

  • “Required implementation pieces” below means runtime artifacts, observable behaviors, registries/profiles, and component responsibilities stated by the contracts. A named artifact does not automatically require a one-to-one Rust type, crate, file, or service.
  • “Verification obligations” means explicit contract conformance requirements and directly stated invariants that a future implementation must make observable and testable.
  • Draft and Frozen architectural status is preserved. No row means that its contract is adopted or implementation-ready.
  • The family-wide invariants apply to every row: Representation != Authorization; Interpretation Proposal != Canonical Request; Construction != Issuance; Issuance != Handoff; Handoff != Execution.

Family-wide verification obligations

Every conforming implementation must make it possible to verify:

  1. one owning authority per transformation and no silent neighboring authority;
  2. immutable upstream publications and linked identities/digests rather than silent rewrites;
  3. exactly one committed success or failure outcome for each completed operation;
  4. valid unresolved, deferred, blocked, rejected, incomplete, and not-applicable states distinctly from operation failure;
  5. declared contract, profile, schema, registry, configuration, and implementation versions for deterministic replay;
  6. no hidden prompt, ambient state, mutable global, provider default, unrecorded operator assumption, live inventory, or undeclared input affects a governed result;
  7. no authorization, provider/model selection, routing, credentials, planning, generation, tool invocation, execution, or release authority is created by representation or issuance.

Matrix

Contract 000 — Architecture, Identity, and Authority

Source/status: SRE-CONTRACT 000.txt; v0.1.0 Candidate — Constitutional Review Passed; Implementation Mapping Pending.

Owned act: Constitute the SRE identity, authority boundary, artifact distinctions, lifecycle outcomes, and invariants.

Required implementation pieces

  • Preserve distinct representations for source submission, interpretation proposal, CanonicalStructuredRequest, authority decision, generation envelope, execution plan, provider request, generated output, and released output.
  • Make the engine boundary accept only declared source/proposal artifacts and versioned contract, profile, registry, and configuration references.
  • Define the family-level success/failure boundary: exactly one CanonicalStructuredRequest or one StructuredRequestFailureRecord for a completed construction transaction.
  • Represent CanonicalStructuredRequest, StructuredRequestFailureRecord, and CanonicalRequestHandoffPackage when handoff occurs; keep other logical artifacts at the appropriate subordinate contract.
  • Provide cross-cutting identity, provenance, immutability, deterministic-behavior, and authority-boundary support rather than a standalone Contract 000 transformation module.
  • Implemented surfaces: Cargo.toml and src/lib.rs provide the bounded source-only foundation: opaque submission/source/operation identities, immutable value publications, explicit success/failure alternatives, deterministic policy binding, and no downstream-authority API.

Verification obligations

  • Verify the artifact distinctions remain observable even when multiple authorities share a process or module.
  • Verify canonicalization never implies approval, safety, feasibility, authentication, provider support, execution, scheduling, or release.
  • Verify undeclared environmental context cannot affect canonical construction.
  • Verify the one-authority-per-transformation and authority-monotonicity invariants.
  • Verify every completed transaction produces exactly one authoritative success or failure outcome, never both or neither.
  • Verify no interpreter, provider, tool, credential, planning, generation, runtime-governance, or release authority is exposed by the SRE boundary.
  • Evidence: docs/Evidence/CONTRACT_000_001_FOUNDATION_AND_SOURCE_ADMISSION_EVIDENCE.md; Rust compile, lint, unit-test, and documentation-test results.

Primary implementation gate: Bounded Contract 000 foundation mapping is implemented and verified for this slice; family adoption and later-contract mappings remain outside scope.

Current implementation status: Verified for the bounded foundation surfaces, with no promotion of Contract 000 status.

Contract 001 — Source Admission

Source/status: Contract 001 sections 001–006; v0.1.0 Draft — Constitutional Development.

Owned act: Admit externally supplied or referenced material as an authoritative source artifact without assigning semantic meaning.

Required implementation pieces

  • A source-intake boundary accepting externally supplied content, resolvable references, and application-supplied submission metadata.
  • Submission identity, source identity, source enumeration, source boundaries, content preservation, mechanically observable metadata, encoding, and admissibility representation.
  • SourceIntakeRecord as the immutable principal publication.
  • SourceIntakeFailureRecord for unsupported, unavailable, malformed, unidentifiable, or unpreservable input.
  • Deterministic intake lifecycle and reconstruction references; admission must not perform later ordering or semantic interpretation.
  • Adapters and preservation storage/reference behavior that do not silently change supplied content.
  • Explicit component-state preservation for each enumerated source component, including accepted, rejected, unavailable, unsupported, incomplete, malformed, redacted, and other contract-authorized states.
  • Implemented surfaces: SourceSubmission, SourceComponentInput, SourcePayload, SourceCategory, SourceOrigin, AdmissionState, ObservableMetadata, PreservationFacts, CompositeAdmissionPolicy, AuthorizedProfile, SourceIntakeRecord, SourceIntakeFailureRecord, IntakeOutcome, and admit in src/lib.rs.

Verification obligations

  • Verify preserved content is byte/content faithful and encoding decisions are explicit.
  • Verify identities, metadata, source boundaries, references, and submission lineage are present and immutable.
  • Verify component states are preserved without silent rejection. Contract 001 now uses the repaired Composite Admission Policy rule to determine whether non-admitted or unresolved components may appear in a committed SourceIntakeRecord or require SourceIntakeFailureRecord.
  • Verify no partial authoritative commitment occurs outside the permitted artifact model, no component condition is collapsed into one undifferentiated failure category, and each completed operation commits exactly one SourceIntakeRecord or one SourceIntakeFailureRecord atomically.
  • Verify admission does not infer objectives, constraints, capabilities, meaning, or authority.
  • Verify equivalent declared intake inputs produce deterministic, replayable results.
  • Evidence: docs/Evidence/CONTRACT_000_001_FOUNDATION_AND_SOURCE_ADMISSION_EVIDENCE.md; nine focused unit tests cover default mapping, replay, enumeration/preservation, references, redaction, missing-preservation rejection, optional-profile rejection, receive-order equivalence, and state/outcome separation.

Primary implementation gate: First bounded runtime candidate is implemented and verified under the default Composite Admission Policy; any profile-controlled variation remains validation-only and requires immutable identity, version binding, complete state mapping, authority, and replay evidence.

Contract 001 disposition: The genuine specification gap is repaired by SRE-001-SOURCE-007 through SRE-001-SOURCE-012 and SRE-001-POLICY-001 through SRE-001-POLICY-006. The default policy is strict, while bounded profile variation is expressly authorized and version-bound.

The implementation mapping must distinguish component-level source/admission state from the operation-level terminal artifact. The repaired policy fixes the observable mapping and does not permit implementation-selected semantics.

Current implementation status: Verified for the complete bounded default-policy slice, with durable persistence/crash recovery and an adopted optional profile explicitly deferred.

Contract 002 — Interpretation Boundary

Source/status: SRE-CONTRACT-002_Interpretation_Boundary_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Bound external interpretation to a deterministic, replayable, non-authoritative proposal-admission boundary.

Required implementation pieces

  • InterpretationRequest, InterpretationProposal, and interpreter identity/version data.
  • Declared interpretation bounds, proposal status, finish status, source scope, profile versions, operation identity, and transport-neutral exchange.
  • InterpretationProposalAdmissionDecision and AdmittedInterpretationProposalSet as immutable admission outputs.
  • InterpretationBoundaryFailureRecord when request issuance, decision construction, or set publication cannot complete; structurally ineligible proposals receive valid negative admission decisions when evaluable.
  • Admission validation that establishes structural eligibility only; duplicate, conflict, precedence, comparison, and reconciliation behavior remains Contract 009.
  • Implemented surfaces: InterpretationOperationContext, InterpretationRequest, InterpretationProposal, ExternalInterpreter, EvidenceCapabilityProfile, InterpretationProposalAdmissionDecision, AdmittedInterpretationProposalSet, InterpretationBoundaryFailureRecord, issue_interpretation_request, admit_interpretation_proposal, and publish_admitted_proposal_set in src/lib.rs.

Verification obligations

  • Preserve the distinction among request, proposal, admission decision, and canonical request.
  • Expose request, proposal, admission, operation, interpreter, source, and profile identities/versions.
  • Demonstrate admission does not evaluate semantic correctness.
  • Demonstrate interpreter output cannot directly alter constitutional state.
  • Demonstrate Contract 002 cannot create canonical interpretation state or CanonicalStructuredRequest.
  • Verify proposals and admission decisions are immutable and a completed operation ends in an explicit committed artifact.
  • Verify valid negative admission decisions remain distinct from boundary operation failure, multiple proposals coexist without precedence, zero-admitted success requires explicit profile permission, and any Contract 003 consumer remains a separate downstream authority.
  • Evidence: docs/Evidence/CONTRACT_002_INTERPRETATION_BOUNDARY_EVIDENCE.md; 17 passing workspace unit tests and passing formatting, check, Clippy, and documentation-test commands.

Primary implementation gate: Contract 002 request/admission boundaries are implemented and verified without binding an interpreter implementation into constitutional authority. Contract 003 consumes only the committed admitted-proposal-set handoff under its own separate authority.

Current implementation status: Verified for the in-memory, fixture-profile-bounded slice; durable persistence and adopted production profile/schema registries remain declared dependencies.

Contract 003 — Objectives and Objective Relationships

Source/status: SRE-CONTRACT-003_Objectives_and_Objective_Relationships_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Represent requested outcomes and their relationships without permission, planning, or execution semantics.

Required implementation pieces

  • DeclaredObjectiveSet, objective representation instances, objective identities, origins, scopes, conditions, relationships, proposal references, and evidence references/status.
  • Support for declared, primary, secondary, conditional, compound, and parallel objective forms where supported by profile.
  • Representation status for unsupported, contradictory, unresolved, or evidence-limited objectives.
  • Objective representation decisions and ObjectiveRepresentationFailureRecord.
  • Immutable set-level publication; later reconciliation owns competition, duplicates, merging, and conflict disposition.

Implemented bounded slice: src/lib.rs consumes exactly one AdmittedInterpretationProposalSet and only its explicit ProposalContent.objective_elements surface. The fixture-only profile contract-003-fixture / fixture-003-v1 and fixture registries fixture-003-registry-v1 are explicit inputs; generic proposed_elements are never scanned, and no production defaults are supplied.

Verification obligations

  • Every committed objective is traceable to admitted proposal material and evidence or an explicitly permitted evidence status.
  • Objective identity is immutable and distinct from source, proposal, set, and canonical-request identities; proposal, set, profile, schema, configuration, and registry bindings remain inspectable.
  • Equivalent declared inputs produce equivalent outcomes.
  • Constraints, capabilities, assumptions, ambiguities, preferences, and execution methods are not silently converted into objectives.
  • No unsupported Primary designation, invented objective, automatic conflict resolution, or silent discard occurs.
  • Unsupported/incomplete/conflicting/unresolved/evidence-limited states remain representable when profile-permitted; committed sets cannot be edited in place; success/failure is atomic.
  • Deterministic ordering is by admitted proposal identity and objective element identity. Primary designation is preserved as a designation/status observation and never becomes execution priority.
  • Profile-authorized decomposition preserves parent/child identity and ComponentOf relationships; unauthorized decomposition terminates with ObjectiveRepresentationFailureRecord.

Contract 004 — Declared Constraints

Source/status: SRE-CONTRACT-004_Declared_Constraints_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Represent source-level limits, requirements, inclusions, exclusions, and conditions without creating policy.

Required implementation pieces

  • DeclaredConstraintSet, constraint identities, origins, scope, conditions, relationships, evidence references/status, and explicit priority only where supplied.
  • Representation for explicit, inferred, application-supplied, and referenced-artifact constraints, including negative, temporal, format, resource, confidentiality, and scope forms.
  • Constraint representation decisions and ConstraintRepresentationFailureRecord.
  • Profile and registry resolution for constraint categories and relationships.
  • Immutable set-level publication; conflict reconciliation and execution enforcement remain outside Contract 004.

Implemented bounded slice: src/lib.rs adds the typed ProposalContent.constraint_elements prerequisite under proposal schema proposal-fixture-v2. represent_constraints consumes exactly one admitted proposal set and one committed DeclaredObjectiveSet, validates their declared lineage before collection, and uses only explicit typed constraint elements.

Verification obligations

  • Preserve declared constraint text/meaning, origin, evidence, scope, applicability, conditions, priority, and conflicts.
  • Verify no policy is invented, no conflicting constraints are silently chosen, and no constraint becomes authority or enforcement.
  • Verify unsupported, incomplete, or unresolved constraints remain representable when profile-permitted.
  • Verify immutable set publication, atomic success/failure, identity separation, and deterministic replay.
  • Verify no operation authorizes execution, chooses a provider, imposes policy, or releases output.
  • Verify unresolved references remain unresolved only when profile-permitted; malformed, prohibited, and foreign-lineage references fail the whole operation without a partial set.
  • Verify declared priority, explicit conflicts, confidentiality class, objective context, and OverridesAsDeclared relationships remain representation observations rather than precedence, redaction, or policy effects.

Contract 005 — Capability Requirements

Source/status: SRE-CONTRACT-005_Capability_Requirements_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Represent abstract capability needs without selecting, granting, checking, or invoking capabilities.

Required implementation pieces

  • CapabilityRequirementSet and CapabilityRequirementRepresentationFailureRecord.
  • Capability requirement identity, description/class, abstraction level, necessity, scope, origin, representation basis, proposal/evidence references, conditions, alternatives, relationships, status, and uncertainty references.
  • Capability representation profile and registries, including profile-authorized cross-domain derivation only where explicitly permitted.
  • Registry-backed immutable set publication and preservation of all consumed source, proposal, objective, constraint, profile, schema, and registry identifiers.

Implemented bounded slice: src/lib.rs adds the typed ProposalContent.capability_elements prerequisite under proposal schema proposal-fixture-v3. represent_capabilities consumes exactly one admitted proposal set plus one objective set and one constraint set, validates exact lineage before construction, and uses only explicitly typed capability elements.

Verification obligations

  • Verify a requirement is not treated as availability, selection, invocation, reservation, credential validation, permission, or provider binding.
  • Verify requirements are not invented from objectives/constraints without admitted support or profile authorization.
  • Verify live inventory, credentials, tools, providers, models, connectors, and methods are not inspected or selected.
  • Verify scope, abstraction, necessity, origin, evidence, uncertainty, and relationships are preserved; committed sets are immutable.
  • Verify equivalent inputs replay identically, output is atomic, and no Contract 005 operation creates GenerationEnvelope or release authority.
  • Verify abstraction and decomposition occur only through explicit closed fixture rules; abstract classes, supplied methods, rule identities, necessity, access dependency, classification support status, and epistemically declared relationships remain observable without availability, binding, authorization, provider, tool, credential, or invocation effects.

Contract 006 — Meaning Qualification Representation

Source/status: SRE-CONTRACT-006_Meaning_Qualification_Representation_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Represent ambiguity, assumptions, and uncertainty explicitly without silently resolving meaning.

Required implementation pieces

  • Coordinated MeaningQualificationSet containing distinct ambiguity, assumption, and uncertainty representations.
  • Ambiguity alternatives, class, scope, severity, consequence/blocking status, clarification references, and relationships.
  • Assumption origin, explicitness, reliance/challenge status, scope, basis, evidence, and lineage.
  • Uncertainty dimensions/status and profile-bounded confidence representation; clarification requirements distinct from clarification requests/dialogue.
  • MeaningQualificationRepresentationFailureRecord, coordinated atomic commitment, and immutable subordinate lineage.

Verification obligations

  • Never collapse ambiguity, assumption, and uncertainty into one field or silently select an alternative.
  • Verify assumptions are not facts, uncertainty is not truth/falsity, and no universal confidence model is forced.
  • Verify no semantic content is manufactured from prior artifacts without authorized support.
  • Verify blocking/unresolved states remain distinct from final completeness adjudication and operation failure.
  • Verify no clarification dialogue is operationalized and no committed set or lineage is mutated in place.
  • Verify equivalent inputs replay identically, coordinated success/failure is atomic, and no authority is expanded.

Contract 007 — Evidence Representation

Source/status: SRE-CONTRACT-007_Evidence_Representation_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Ground represented claims in explicit support relationships without evaluating truth or authorization.

Required implementation pieces

  • InterpretationEvidenceSet, evidence representation instances, evidence subjects/items, source spans, referenced artifacts, declared origins, and support relationship types.
  • Evidence Identity, Evidence Representation Identity, Evidence Status, Representation Status, Evidence Origin, Representation Basis, source spans, constitutionally supplied quoted text, structured evidence fields, referenced artifacts, evidence integrity state, explicit Grounding Assertions, supported-artifact references, and profile-authorized unsupported, unavailable, incomplete, conflicting, external, composite, and other represented states.
  • Immutable InterpretationEvidenceSet publication and EvidenceRepresentationFailureRecord.
  • Explicit Grounding Assertions and required evidence profiles/relationship registries.
  • Evidence representation decisions and EvidenceRepresentationFailureRecord.
  • Immutable, replayable grounding publication with independent evidence and provenance handling.

Verification obligations

  • Verify every evidence relationship points to admitted sources/origins or an explicit supported status.
  • Verify evidence status, representation status, unsupported-artifact accounting, evidence-limited conditions, and explicit Grounding Assertions are represented without any evidentiary adequacy field, score, or determination.
  • Prohibit evidence sufficiency determination, reliability scoring, persuasive weighting, truth determination, semantic correctness determination, relevance adjudication, and confidence assignment by Contract 007.
  • Verify claims are not altered and provenance is not reinterpreted as evidence.
  • Verify profile/registry versions, identities, integrity, immutability, replay, and atomic success/failure.
  • Verify the implementation remains conforming to ARCH-001/ARCH-002 requirements identified by Contract 007.

Contract 008 — Provenance Representation

Source/status: SRE-CONTRACT-008_Provenance_Representation_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Trace the represented constitutional history of artifacts and operations.

Required implementation pieces

  • ProvenanceRecordSet, provenance subjects/instances, lineage assertions, and provenance events.
  • Transformation, custody, publication, replacement, supersession, application, interpreter, registry, configuration, and artifact lineage references.
  • Deterministic reconstruction references, event/lineage registries, provenance profiles, and ProvenanceRepresentationFailureRecord.
  • Immutable set-level publication; evidence remains Contract 007’s distinct concern.
  • ARCH-003 must remain provisional evidence only and must not be a normative dependency.

Verification obligations

  • Verify ancestry, event, custody, publication, replacement, supersession, and temporal context are preserved without rewriting history.
  • Verify provenance does not evaluate evidence, truth, quality, trust, or authority.
  • Verify every required lineage/event is attributable, identity-bound, immutable, and replayable.
  • Verify profile/registry/version capture and atomic success/failure.
  • Verify the implementation treats ARCH-003 as non-binding evidence only.

Inherited architecture mapping — Contracts 003–008

Contracts 003–008 inherit the bounded representation pattern in SRE-ARCH-001_Canonical_Representation_Pattern_v0.1.0_Draft.md: one owning authority performs one bounded act over a declared logical domain, with an operation identity, logical domain-object identities, immutable representation identities, profile and registry snapshots, a principal successful set publication, a contract-specific failure publication, atomic exactly-one success/failure commitment, and immutable publications. Each implementation slice must make valid empty or no-content results observable where the contract/profile permits them, and must expose a downstream handoff boundary without granting downstream authority. SRE-ARCH-003 is provisional evidence only and is not inherited or binding.

Contract 003 — Objectives

  • Domain/authority: objective and objective-relationship representation; Contract 003 authority only.
  • Identity and inputs: operation identity; objective and DeclaredObjectiveSet logical identities; immutable representation identities; objective profile and registry snapshots.
  • Publication: immutable DeclaredObjectiveSet on success or ObjectiveRepresentationFailureRecord on operation failure, atomically and exactly one; an empty valid objective set is representable where the profile permits it.
  • Boundary/deviation: downstream reconciliation, not execution or authorization; no deviation from ARCH-001 is presently adopted.

Contract 004 — Declared constraints

  • Domain/authority: source-level constraint representation; Contract 004 authority only.
  • Identity and inputs: operation identity; constraint and DeclaredConstraintSet logical identities; immutable representation identities; constraint profile and registry snapshots.
  • Publication: immutable DeclaredConstraintSet on success or ConstraintRepresentationFailureRecord on operation failure, atomically and exactly one; valid empty/no-content constraint representation follows the adopted profile.
  • Boundary/deviation: reconciliation and enforcement remain outside Contract 004; no deviation from ARCH-001 is presently adopted.

Contract 005 — Capability requirements

  • Domain/authority: abstract capability-need representation, never availability or selection; Contract 005 authority only.
  • Identity and inputs: operation identity; capability and CapabilityRequirementSet logical identities; immutable representation identities; capability profile and registry snapshots.
  • Publication: immutable CapabilityRequirementSet on success or CapabilityRequirementRepresentationFailureRecord on operation failure, atomically and exactly one; valid empty/no-content output follows the profile.
  • Boundary/deviation: provider, tool, credential, and execution selection remain outside the boundary; no deviation from ARCH-001 is presently adopted.

Contract 006 — Meaning qualification

  • Domain/authority: ambiguity, assumption, and uncertainty representation; Contract 006 authority only.
  • Identity and inputs: operation identity; qualification and coordinated MeaningQualificationSet logical identities; immutable representation identities; qualification profile and registry snapshots.
  • Publication: immutable coordinated set on success or MeaningQualificationRepresentationFailureRecord on operation failure, atomically and exactly one; an empty qualification set is valid where no qualifications are represented and the profile permits it.
  • Boundary/deviation: no semantic resolution, dialogue, or confidence authority; no deviation from ARCH-001 is presently adopted.

Contract 007 — Evidence and grounding

  • Domain/authority: evidence representation and explicit grounding assertions; Contract 007 authority only.
  • Identity and inputs: operation identity; evidence item/subject and InterpretationEvidenceSet logical identities; immutable representation identities; evidence profile and relationship-registry snapshots.
  • Publication: immutable InterpretationEvidenceSet on success or EvidenceRepresentationFailureRecord on operation failure, atomically and exactly one; valid unsupported, unavailable, incomplete, conflicting, external, composite, or no-evidence states remain profile-authorized representations.
  • ARCH-002 relationship: preserve Semantic Representation != Evidence Representation != Grounding != Provenance; Contract 007 represents evidence and grounding relationships but does not determine truth, relevance, reliability, sufficiency, or confidence.
  • Boundary/deviation: downstream semantic standing and provenance remain separate authorities; no deviation from ARCH-001/ARCH-002 is presently adopted.

Contract 008 — Provenance

  • Domain/authority: constitutional history, lineage, and event representation; Contract 008 authority only.
  • Identity and inputs: operation identity; provenance subject/event and ProvenanceRecordSet logical identities; immutable representation identities; provenance profile and event/lineage-registry snapshots.
  • Publication: immutable ProvenanceRecordSet on success or ProvenanceRepresentationFailureRecord on operation failure, atomically and exactly one; valid empty/no-content lineage follows the adopted profile.
  • ARCH-002 relationship: provenance remains distinct from both semantic and evidence representations and from grounding; it records lineage rather than evaluating support or truth.
  • Boundary/deviation: custody and downstream lifecycle semantics are not created by provenance representation; SRE-ARCH-003 is not a dependency and no deviation from ARCH-001/ARCH-002 is presently adopted.

Contract 009 — Semantic Reconciliation

Source/status: SRE-CONTRACT-009_Semantic_Reconciliation_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Assign governed downstream semantic standing to admitted alternatives while preserving plurality.

Required implementation pieces

  • Reconciliation subjects/groups, eligibility rules, bounded cross-domain conflict classification, and profile-authorized comparison.
  • Duplicate, equivalence, compatibility, complementarity, alternative, competition, and conflict treatment.
  • Merged, Selected, Preserved, Split, Deferred, Rejected, and Unresolved dispositions.
  • ReconciliationDecision, ReconciledSemanticElement, SemanticReconciliationSet, ReconciliationDecisionSet, conflict/alternative records, and SemanticReconciliationFailureRecord.
  • Deterministic profile/registry tie-breaking, decision basis, preserved/rejected alternatives, and distinction between unresolved valid state and operation failure.

Verification obligations

  • Preserve distinctions among subject, group, decision, standing, element, and set.
  • Preserve every material upstream alternative and decision basis; every standing is attributable to exactly one decision.
  • Verify no unsupported semantic invention, hidden context, nondeterministic iteration, or automatic precedence from lineage/evidence/model confidence.
  • Verify unresolved, deferred, split, or blocked outcomes can be successful where profile-permitted and remain distinct from failure.
  • Verify upstream immutability, deterministic replay, atomic outcome, and no normalization/order/validation/construction/issuance/handoff authority.

Contract 010 — Semantic Normalization

Source/status: SRE-CONTRACT-010_Semantic_Normalization_v0.1.0_Draft.md; v0.1.0 Draft; formal status field not separately declared.

Owned act: Express reconciled semantic elements in stable, meaning-preserving canonical forms.

Required implementation pieces

  • SemanticNormalizationInput, NormalizedRequestRepresentation, and NormalizationFailureRecord.
  • Lexical, identifier, enum/vocabulary, whitespace, encoding, numeric, temporal, unit, locale, collection, and post-reconciliation duplicate normalization rules.
  • SemanticNormalizationAuthority, a versioned NormalizationProfile, version-bound inputs, distinct operation/input/output identities, mapping/decision records, source/prior-form references, reversibility references, and idempotent normalization.
  • Element dispositions Mapped, Identity, Preserved, and profile-authorized Deferred, with explicit valid non-transformation versus operation failure.
  • Exactly one terminal NormalizedRequestRepresentation or NormalizationFailureRecord, published immutably and atomically; deterministic replay/equivalence under the same declared inputs and versions.
  • Deterministic normalization independent of ordering, validation, construction, issuance, and handoff; explicit 009-to-010 and 010-to-011 boundaries.

Implementation status (2026-08-04): Implemented and verified as a fixture-profile-driven, closed-mapping, in-memory reference slice. ReconciledSemanticElement now carries the explicit normalization-source expression and semantic context supplied by Contract 009; normalization validates the exact set binding and standing assignment before applying a profile-authorized rule. Production profile, registry ownership, mapping authority, durable persistence, and broader fixture coverage remain dependencies.

Verification obligations

  • Verify normalized output preserves semantic scope/intent, identity, evidence, provenance, standing, and prior forms.
  • Verify repeated application under the same profile is idempotent.
  • Verify no remaining conflict, uncertainty, alternative, or missing data is silently resolved/discarded/invented.
  • Verify deterministic replay/equivalence, atomic immutable terminal publication, and explicit failure when meaning cannot be preserved.
  • Verify output cannot declare structural validity, issue identity, authorize, or transfer the request.

Contract 011 — Canonical Ordering

Source/status: SRE-CONTRACT-011_Canonical_Ordering_v0.1.0_Draft.md; v0.1.0 Draft; formal status field not separately declared.

Owned act: Establish deterministic sequence and structural placement of normalized elements.

Required implementation pieces

  • CanonicallyOrderedRequestRepresentation and CanonicalOrderingFailureRecord.
  • Ordering of objectives, constraints, capability requirements, ambiguity/assumption/uncertainty, evidence, provenance, reconciliation decisions, relationships, and nested collections.
  • CanonicalOrderingAuthority, a versioned CanonicalOrderingProfile, version-bound inputs, distinct operation/order/publication identities and roles, scopes/assignments, registry-defined keys, stable tie-break rules, and explicit ordering decision records.
  • Explicit underdetermination, cycle, contradiction, and tie-break mappings, including valid non-success ordering dispositions distinct from operation failure.
  • Exactly one terminal CanonicallyOrderedRequestRepresentation or CanonicalOrderingFailureRecord, published immutably and atomically; deterministic replay/equivalence under the same declared inputs and versions.
  • Ordering independent of insertion/source order, serialization bytes, validation, construction, issuance, and handoff; explicit 010-to-011 and 011-to-012 boundaries.

Verification obligations

  • Equivalent inputs produce equivalent order under the same profile and registry versions.
  • Verify ordering does not change normalized values, merge/drop elements, resolve conflicts, declare validity, serialize, or issue.
  • Verify nested and related collections use stable keys and explicit tie-break decisions.
  • Verify lawful underdetermination and deterministic order failure are explicit and distinct from downstream validation failure.
  • Verify ordered output preserves identities, canonical expression, meaning, standing, evidence, and provenance.

Contract 012 — Structural Validation

Source/status: SRE-CONTRACT-012_Structural_Validation_v0.1.0_Draft.md; v0.1.0 Draft — Constitutional Development.

Owned act: Evaluate structural conformance and construction eligibility without mutation or semantic resolution.

Required implementation pieces

  • StructuralValidationResult and StructuralValidationFailureRecord.
  • Validation Rule Applications, Validation Findings, Validation Decisions, explicit completion state, structural eligibility state, and rule-level deterministic reports.
  • Required/optional/cardinality rules, relationship/reference/identifier integrity, profile/schema/version compatibility, cross-domain structural consistency, reconciliation-disposition completeness, and valid unresolved/deferred/not-applicable treatment.
  • Structural validation profile, rule registry, construction requirements, and exact upstream references.

Verification obligations

  • Consume one immutable ordered representation and identify every governing profile, schema, registry, rule set, and version.
  • Preserve rule authority outside the validator; distinguish completion, eligibility, severity, findings, decisions, and operation failure.
  • Treat Ineligible as a completed result; restrict Deferred to profile-authorized states.
  • Perform no repair, mutation, reordering, semantic interpretation, conflict resolution, construction, or issuance.
  • Commit exactly one immutable result or failure, support deterministic replay, and transfer only eligible results to Contract 013.
  • For failed validation, preserve attempted context, publish Failed/NotDetermined, and publish no partial authoritative result or ineligibility determination.

Contract 013 — Canonical Request Construction

Source/status: SRE-CONTRACT-013_Canonical_Request_Construction_v0.1.0_Draft.md; v0.1.0 Draft; Architectural status Frozen, not canonized.

Owned act: Mechanically assemble one pre-issuance canonical request from the exact eligible ordered representation.

Required implementation pieces

  • ConstructedCanonicalRequest, complete Construction Manifest, Construction Decisions, and CanonicalRequestConstructionFailureRecord.
  • Exact representation-and-validation binding verification; profile/schema/rule-set/registry/configuration/contract/implementation version resolution.
  • Deterministic logical artifact builder that embeds required objective, constraint, capability, clarification, evidence, provenance, profile, and validation references.
  • Atomic artifact-and-manifest publication; serialization-independent construction; identity separate from issued request identity.

Verification obligations

  • Consume exactly one immutable ordered representation and exactly one completed validation result bound to that exact representation.
  • Verify eligibility binding without revalidation; perform no repair, substitution, reordering, normalization, semantic invention, or hidden input use.
  • Preserve meaning, expression, identity, order, standing, evidence, provenance, and validation lineage.
  • Publish complete artifact and manifest together, record all material decisions/authorized omissions, and keep success/failure mutually exclusive.
  • Verify deterministic replay, immutable history, no issued identity, no authorization, and transfer only the successful publication set to Contract 014.

Contract 014 — Canonical Request Identity and Issuance

Source/status: SRE-CONTRACT-014_Canonical_Request_Identity_and_Issuance_v0.1.0_Draft.md; v0.1.0 Draft; Architectural status Frozen, not canonized.

Owned act: Derive deterministic identity and commit formal issuance standing without implying authorization.

Required implementation pieces

  • CanonicalStructuredRequest, CanonicalRequestIssuanceRecord, Issuance Manifest, identity derivation manifest, and CanonicalRequestIssuanceFailureRecord.
  • Construction Publication Set binding verifier; Issuance Context resolver; Identity Policy and Issuance Profile resolvers.
  • Deterministic identity derivation; exact binding to one immutable Construction Publication Set; canonical serialization/digest binding; registry/schema/version capture.
  • Issued-request identity within a governed Issuance Context; same-context uniqueness; idempotent replay by default; context-distinct issuance where constitutionally permitted; event-unique issuance only where an applicable Identity Policy expressly authorizes it and declares all identity-bearing inputs.
  • Initial constitutional standing; atomic publication of CanonicalStructuredRequest and IssuanceManifest; immutable issuance failure representation.
  • Detect and reject unauthorized replacement, renewal, correction, supersession, or lifecycle reissuance. Contract 014 does not independently authorize supersession, replacement, renewal, correction, revocation, suspension, expiration, withdrawal, or post-issuance lifecycle mutation.

Verification obligations

  • Bind exactly one construction publication set, issuance activity/context, issued request, manifest, and initial standing on success.
  • Verify construction content is unchanged and issued identity is distinct from construction identity.
  • Verify manifest is mandatory, publication is atomic, same-context replay is idempotent by default, and context-distinct issuance is explicit.
  • Verify successful issuance exposes exact source construction set, context, authority, profile/policy/rule/registry/version inputs, derivation result, standing, and commitment.
  • Verify identity collision/replay behavior, immutable historical records, deterministic serialization/digests, and explicit issuance failure.
  • Verify issuance does not approve, authorize, select execution, or transfer custody.
  • Verify unauthorized replacement, renewal, correction, supersession, revocation, suspension, expiration, withdrawal, and lifecycle reissuance are rejected rather than treated as Contract 014 operations.

Implementation discrepancy: the adopted planning baseline may contain broader Contract 014 lifecycle language; the frozen Contract 014 authority boundary limits this contract to initial issuance and the expressly governed replay/context/event-unique cases above. No later lifecycle authority is invented here.

Contract 015 — Canonical Request Handoff

Source/status: SRE-CONTRACT-015_Canonical_Request_Handoff_v0.1.0_Draft.md; v0.1.0 Draft; Architectural status Frozen, not canonized.

Owned act: Transfer an issued request to a declared downstream boundary while preserving identity, integrity, provenance, and non-authorization.

Required implementation pieces

  • One exact immutable Issuance Publication Set; one applicable immutable DownstreamBoundaryDeclaration version; one governed HandoffContext; one HandoffPackageManifest; zero or more identified TransferAttempt records where transfer is attempted; one independently attributable ReceiptAcknowledgment when produced or relied upon; one CustodyDisposition; one HandoffResponsibilityDisposition; and exactly one terminal CanonicalRequestHandoffRecord or exactly one terminal CanonicalRequestHandoffFailureRecord.
  • Declared recipient/boundary identity and handoff profile; transport-neutral package and adapter.
  • Transfer event, custody, integrity verification, acknowledgment, provenance continuation, and profile-governed terminal dispositions including retry, duplicate, expiration, and unavailable-recipient states.
  • Idempotency/retry handling that never mutates the issued request.
  • CustodyDisposition != HandoffResponsibilityDisposition; success and failure terminal records are alternatives, not a joint publication set. Receipt is not approval, custody is not authority, and handoff responsibility is not execution authority. An endpoint/address does not substitute for downstream constitutional boundary identity. The sender must never originate, fabricate, impersonate, rewrite, or silently repair a recipient acknowledgment; absence of acknowledgment may still permit terminal disposition only where the governing profile authorizes it.

Verification obligations

  • Verify the handoff contains the exact issued request and issuance record with preserved identity, integrity, provenance, and versions.
  • Verify recipient identity and transfer event are explicit; acknowledgments never imply more than the recorded state.
  • Verify delivered, acknowledged, rejected, expired, unavailable, duplicate, and retry outcomes are profile-defined and distinguishable from transfer-operation failure.
  • Verify exact artifact binding, immutable atomic publication, provenance continuation, and safe/idempotent retries. Preserve separate custody and handoff-responsibility dispositions and exactly one terminal success-or-failure alternative.
  • Verify handoff does not authorize, claim downstream acceptance, mutate the request, select providers, plan, invoke tools, execute, generate, or release output.

Family implementation gates extracted from the contracts

Before a complete implementation can claim conformance, the repository still needs explicit, versioned ownership for the profiles, registries, schemas, identity algorithms, canonical serialization, compatibility rules, and failure/valid-non-success state vocabulary referenced throughout the family. Those are implementation prerequisites identified by the contracts; this document does not invent them.

The contracts permit implementation grouping across the proposed structured-request-contracts, structured-request-engine, and structured-request-seam packages, provided inputs/outputs remain inspectable, upstream artifacts remain immutable, each principal publication is independently testable, registry/profile versions are recorded, and no module silently performs another contract’s act.

Observability and specification-gap audit — Contracts 002–015

This audit applies the test: two conforming implementations may vary internally only when they produce equivalent externally observable constitutional behavior under the same declared inputs and version context. The dispositions below are audit dispositions, not contract-status promotions or implementation authorization.

Contract 002 — Interpretation Boundary

  • Governing question / owned act: Admit interpretation requests and proposals at a structural, non-authoritative boundary; the contract explicitly separates Interpretation Request Authority from Proposal Admission Authority.
  • Principal success / failure publications: InterpretationRequest or InterpretationProposalAdmissionDecision; InterpretationBoundaryFailureRecord where the bounded operation cannot complete.
  • Current readiness / disposition: CONTRACT 003: VERIFIED WITH DECLARED PROFILE AND REGISTRY DEPENDENCIES for the in-memory fixture-bounded slice.
  • Observability findings: Production state, admission disposition, evidence status, proposal identity, and one-outcome commitment are distinct. Empty proposals are profile-permitted only with explicit no-result authority. Duplicate, conflict, precedence, and reconciliation remain Contract 009 responsibilities.
  • Internal mechanisms: Interpreter invocation, parser, process/module layout, storage, and proposal-processing algorithms may vary when fixed admitted inputs produce equivalent request artifacts and admission dispositions.
  • Observable decisions already governed: Immutable proposal submission, structural-only admission, explicit dispositions, immutable decisions, deterministic request/admission outcomes, and no semantic evaluation.
  • Authorized dependencies: Interpreter Profile, evidence capability profile, proposal/schema versions, registries, contract/configuration versions; the contract requires their identity and version binding.
  • Mixed decomposition: Profile/schema semantics are observable; resolver, parser, and persistence mechanisms are internal.
  • Specification gaps: None identified in this audit.
  • Boundaries / repair: Keep reconciliation, comparison, precedence, normalization, ordering, construction, issuance, and handoff outside Contract 002. No repair required.
  • Evidence: SRE-002-REQUEST-OUTCOME-001–003, SRE-002-ADMISSION-006, SRE-002-DECISION-001–005, SRE-002-DISPOSITION-001–004, SRE-002-COMMIT-001–003, SRE-002-DETERMINISM-001–003.

Contract 003 — Objectives and Objective Relationships

  • Governing question / owned act: Represent requested outcomes and objective relationships without preference, reconciliation, or authority.
  • Principal success / failure publications: DeclaredObjectiveSet; ObjectiveRepresentationFailureRecord.
  • Current readiness / disposition: CONTRACT 004: VERIFIED WITH DECLARED PROFILE AND REGISTRY DEPENDENCIES for the in-memory fixture-bounded slice.
  • Observability findings: Empty sets, unsupported/incomplete/conflicting/unresolved/evidence-limited objective states, preserved competing objectives, explicit upstream bindings, and atomic success/failure are explicitly distinguished.
  • Internal mechanisms: Representation data structures, normalization routines, graph traversal, indexing, and storage may vary if identities, statuses, lineage, and output equivalence remain observable.
  • Observable decisions already governed: No silent merge, selection, discard, or semantic normalization; exact set identity, input lineage, immutable publication, and deterministic replay.
  • Authorized dependencies: Objective Representation Profile, evidence capability profiles, schemas, registries, and versioned configuration. Profile-authorized decomposition is bounded to deterministic representation without semantic invention.
  • Mixed decomposition: Profile-controlled representation mechanics are distinct from objective status and set-level outcome semantics.
  • Specification gaps: None identified in this audit.
  • Boundaries / repair: Representation-preserving normalization cannot leak Contract 010 authority; reconciliation remains Contract 009. No repair required.
  • Evidence: docs/Evidence/CONTRACT_003_OBJECTIVES_AND_OBJECTIVE_RELATIONSHIPS_EVIDENCE.md; contract_003_tests in src/lib.rs; cargo test --workspace.

Contract 004 — Declared Constraints

  • Governing question / owned act: Represent source-level constraints without creating policy, precedence, enforcement, or feasibility authority.
  • Principal success / failure publications: DeclaredConstraintSet; ConstraintRepresentationFailureRecord.
  • Current readiness / disposition: Profile-dependent; IMPLEMENTATION-READY WITH DECLARED PROFILE DEPENDENCIES.
  • Observability findings: Empty sets, incomplete/unsupported/conflicting/evidence-limited/unresolved/scope-unresolved states, explicit priority versus precedence, references, lineage, and conflict preservation are separately represented.
  • Internal mechanisms: Constraint collection, indexing, relationship processing, storage, and implementation grouping may vary under equivalent outputs.
  • Observable decisions already governed: All source-supported constraints and conflicts remain represented; no winner selection, silent merge, or policy conversion; exactly one atomic outcome.
  • Authorized dependencies: Fixture-only Constraint Representation Profile contract-004-fixture / fixture-004-v1, eight version-bound fixture registries, schema/configuration bindings, the Contract 002 proposal-fixture-v2 amendment, and the Contract 003 objective-set lineage. These do not create production or constitutional defaults.
  • Mixed decomposition: Registry/profile vocabulary is observable; registry storage and lookup implementation are internal.
  • Specification gaps: None identified in this audit.
  • Boundaries / repair: Enforcement, precedence, feasibility, and downstream policy remain outside Contract 004. No repair required.
  • Evidence: docs/Evidence/CONTRACT_004_DECLARED_CONSTRAINTS_EVIDENCE.md; contract_004_tests in src/lib.rs; cargo test --workspace.

  • Principal success / failure publications: CapabilityRequirementSet; CapabilityRequirementRepresentationFailureRecord.
  • Current readiness / disposition: CONTRACT 005: VERIFIED WITH DECLARED PROFILE AND REGISTRY DEPENDENCIES for the in-memory fixture-bounded slice.
  • Observability findings: Abstraction, class, necessity, scope, scope-resolution status, alternatives, unsupported/unresolved states, access dependency, classification support, empty output, lineage, and operation failure are distinct. Profile-authorized abstraction/decomposition is closed and deterministic.
  • Internal mechanisms: Capability extraction, association indexes, registry lookup, and storage may vary if abstract representation and lineage remain equivalent.
  • Observable decisions already governed: No provider/tool/credential selection; no automatic objective/constraint conversion; omitted inferred capabilities are not automatically failure when profile-permitted.
  • Authorized dependencies: Fixture-only Capability Representation Profile contract-005-fixture / fixture-005-v1, eight version-bound fixture registries, schema/configuration/implementation bindings, Contract 002 proposal schema proposal-fixture-v3, and exact Contract 003/004 lineage. These are not production or constitutional defaults.
  • Mixed decomposition: Cross-domain derivation semantics are observable; derivation engine and registry implementation are internal.
  • Specification gaps: None identified in this audit.
  • Boundaries / repair: Availability, feasibility, authorization, and provider binding remain outside Contract 005. No repair required.
  • Evidence: docs/Evidence/CONTRACT_005_CAPABILITY_REQUIREMENTS_EVIDENCE.md; contract_005_tests in src/lib.rs; cargo test --workspace.

Contract 006 — Meaning Qualification Representation

  • Governing question / owned act: Represent ambiguity, assumptions, and uncertainty without resolving meaning or creating clarification authority.
  • Principal success / failure publications: Coordinated MeaningQualificationSet with AmbiguitySet, AssumptionSet, and UncertaintyRecordSet; MeaningQualificationRepresentationFailureRecord.
  • Current readiness / disposition: Profile-dependent; IMPLEMENTATION-READY WITH DECLARED PROFILE DEPENDENCIES.
  • Observability findings: Empty subordinate sets, unresolved/challenged/relied-upon/profile-blocked states, non-truth assumptions, uncertainty scales, and coordinated atomic commitment are explicitly distinguished.
  • Internal mechanisms: Coordination order, subordinate storage, indexes, and equivalent recomputation mechanisms may vary while preserving subordinate identities and coordinated outcome.
  • Observable decisions already governed: No silent alternative selection, assumption-to-fact conversion, uncertainty-to-truth conversion, or clarification dialogue; successor operations create new identities.
  • Authorized dependencies: Meaning Qualification Profile, uncertainty scales, status/origin/basis/severity/relationship registries, schemas, evidence, and version bindings.
  • Mixed decomposition: Profile mechanics may vary; ambiguity/assumption/uncertainty semantics and coordinated outcome may not.
  • Specification gaps: None identified in this audit.
  • Boundaries / repair: Reconciliation, semantic equivalence, and alternative selection remain deferred to Contract 009. No repair required.
  • Evidence: SRE-006-PROFILE-001–006, SRE-006-EMPTY-001–005, SRE-006-FAILURE-001–003, SRE-006-COMMIT-001–005, SRE-006-DETERMINISM-001–003.

Implementation status (2026-08-04): CONTRACT 006: VERIFIED WITH DECLARED PROFILE AND REGISTRY DEPENDENCIES. The bounded runtime adds typed ProposalContent.clarification_elements under proposal schema proposal-fixture-v4, preserves ambiguity, assumptions, uncertainty, clarification requirements, alternatives, relationships, evidence references, and exact Contracts 002–005 lineage, and publishes exactly one coordinated success or failure outcome. Fixture profile, registries, schema/configuration, and in-memory persistence remain declared dependencies; Contract 007 is untouched.

Contract 007 — Evidence Representation and Grounding

  • Governing question / owned act: Represent evidence and explicit grounding relationships without truth, sufficiency, relevance, reliability, or confidence judgment.
  • Principal success / failure publications: InterpretationEvidenceSet; EvidenceRepresentationFailureRecord.
  • Current readiness / disposition: CONTRACT 007: VERIFIED WITH DECLARED PROFILE AND REGISTRY DEPENDENCIES for the bounded fixture implementation.
  • Observability findings: Evidence Status, Representation Status, source spans, quoted text where supplied, referenced artifacts, unsupported/unavailable/incomplete/conflicting/external/composite states, Grounding Assertions, immutable publication, and empty-set rules are governed. Semantic Representation != Evidence Representation != Grounding != Provenance remains enforced.
  • Internal mechanisms: Evidence indexing, span extraction, integrity-check implementation, and storage may vary when evidence identity, integrity, grounding references, and terminal outcome remain equivalent.
  • Observable decisions already governed: Every grounding assertion binds one evidence representation to one supported artifact; unsupported-artifact accounting is explicit; no adequacy or truth judgment is assigned.
  • Authorized dependencies: Grounding Representation Profile, evidence/status/class/relationship registries, supported-artifact rules, schemas, and versioned inputs.
  • Mixed decomposition: Evidence/grounding semantics are observable; evidence extraction and persistence mechanisms are internal.
  • Specification gaps: None identified in this audit.
  • Boundaries / repair: No sufficiency, relevance, reliability, confidence, or truth authority; provenance remains Contract 008. No repair required.

Implementation status (2026-08-04): CONTRACT 007: VERIFIED WITH DECLARED PROFILE AND REGISTRY DEPENDENCIES. The bounded runtime adds typed ProposalContent.evidence_elements under proposal-fixture-v5, preserves declaration/material/representation separation, explicit grounding, status dimensions, target references, ungrounded accounting, exact Contracts 002–006 lineage, deterministic replay, and one terminal success/failure outcome. Contract 008 remains untouched.

Contract 008 — Provenance Representation

  • Governing question / owned act: Represent artifact and operation history, lineage, and typed events without truth, trust, or lifecycle authority.
  • Principal success / failure publications: ProvenanceRecordSet; ProvenanceRepresentationFailureRecord.
  • Current readiness / disposition: CONTRACT 008: VERIFIED WITH DECLARED FIXTURE PROFILE, REGISTRY, SCHEMA, CONFIGURATION, RULE, IDENTITY, REPLAY, AND PERSISTENCE DEPENDENCIES for the bounded fixture implementation.
  • Observability findings: Subject, representation, lineage assertion, event identity, event class, event basis, custody relationship, publication disposition, empty history, conflict, and immutable set-level outcome are distinct.
  • Internal mechanisms: Event storage, lineage graph, reconstruction indexes, and temporal query implementation may vary under equivalent provenance records.
  • Observable decisions already governed: Supersedes/replaces remain representational; history is not rewritten; empty history does not imply no history; provenance does not establish truth or trust.
  • Authorized dependencies: Provenance Representation Profile, event/lineage/transformation/custody/publication registries, schemas, and version snapshots.
  • Mixed decomposition: Event and lineage semantics are observable; graph/storage/reconstruction mechanisms are internal.
  • Specification gaps: None identified in this audit.
  • Boundaries / repair: SRE-ARCH-003 is non-binding evidence only; no lifecycle authority is created. No repair required.
  • Evidence: SRE-008-PROFILE-*, SRE-008-EMPTY-001–003, provenance status/conflict clauses, and terminal commitment clauses.

Implementation status (2026-08-04): Contract 008 remains verified as documented in docs/Evidence/CONTRACT_008_PROVENANCE_REPRESENTATION_EVIDENCE.md. Contract 009 is implemented and verified as a fixture-profile-bounded in-memory reconciliation slice documented in docs/Evidence/CONTRACT_009_SEMANTIC_RECONCILIATION_EVIDENCE.md. Contract 010 is implemented and verified as a fixture-profile-driven, closed-mapping, in-memory normalization slice documented in docs/Evidence/CONTRACT_010_SEMANTIC_NORMALIZATION_EVIDENCE.md; production profile and registry ownership, broader mappings, durable persistence, and production conformance remain unresolved.

Valid unresolved or deferred reconciliation is not failure.
  • Internal mechanisms: Comparison algorithms, grouping indexes, graph traversal, and storage may vary only under equivalent declared profile/rule results.

  • Observability findings: SemanticNormalizationAuthority, version-bound inputs and profile, distinct operation/input/output identities, element dispositions (Mapped, Identity, Preserved, profile-authorized Deferred), exact terminal alternatives, immutable atomic publication, and replay/equivalence are now explicit.
  • Internal mechanisms: Mapping algorithm, normalization data structures, persistence, and replay engine may vary when the repaired observable results and bindings remain equivalent.
  • Observable decisions already governed: Meaning preservation, no semantic reinterpretation, profile-governed canonical expression, valid non-transformation versus operation failure, and the 009-to-010 and 010-to-011 boundaries.
  • Authorized dependencies: Profile content, registry snapshots, mapping rules, schemas, configuration ownership, and implementation evidence remain to be identified, version-bound, and adopted; the repair does not adopt them.
  • Mixed decomposition: Canonical expression, element dispositions, identities, terminal outcome, commitment, and replay equivalence are observable; mapping engine and storage are internal.
  • Specification gaps: None identified after the narrow repair. Remaining items are declared profile, registry, rule, schema, configuration, evidence, and implementation dependencies.
  • Cross-contract boundary / repair: The repair is closed. Do not expand Contract 010 into ordering or validation; downstream work must consume the exact normalized terminal publication.
  • Evidence: Contract 010 clauses SRE-010-AUTHORITY-*, SRE-010-PROFILE-*, SRE-010-IDENTITY-*, SRE-010-ELEMENT-*, SRE-010-OUTCOME-*, SRE-010-COMMIT-*, SRE-010-REPLAY-*, and SRE-010-HANDOFF-*.

  • Current readiness / disposition: IMPLEMENTED — VERIFIED WITH DECLARED FIXTURE PROFILE, REGISTRIES, RULES, SCHEMA, CONFIGURATION, IDENTITY, REPLAY, AND PERSISTENCE DEPENDENCIES.
  • Observability findings: CanonicalOrderingAuthority, version-bound inputs and profile, distinct operation/order/publication identities and roles, scopes/assignments, underdetermination/cycle/contradiction/tie-break handling, exact terminal alternatives, immutable atomic publication, and replay/equivalence are now explicit.
  • Internal mechanisms: Topological sorting, comparator implementation, traversal, indexes, persistence, and replay engine may vary when repaired observable ordering results and bindings remain equivalent.
  • Observable decisions already governed: Serialization-independent arrangement, preserved normalized identities, no semantic priority, valid underdetermined ordering versus operation failure, explicit cycle/contradiction/tie-break handling, and the 010-to-011 and 011-to-012 boundaries.
  • Authorized dependencies: Ordering profile content, registries, constraints, comparison/traversal/tie-break rules, schemas, configuration ownership, and implementation evidence remain to be identified, version-bound, and adopted; the repair does not adopt them.
  • Mixed decomposition: Ordering semantics, identities, assignments, terminal outcome, commitment, and replay equivalence are observable; linearization algorithm and storage are internal.
  • Specification gaps: None identified after the narrow repair. Remaining items are declared production ordering profile, registry, constraint, rule, schema, configuration, evidence, durable persistence, and production conformance dependencies.
  • Cross-contract boundary / repair: The repair is closed. Do not add validation or construction authority; downstream work must consume the exact ordered terminal publication.
  • Evidence: Contract 011 clauses SRE-011-AUTHORITY-*, SRE-011-PROFILE-*, SRE-011-IDENTITY-*, SRE-011-SCOPE-*, SRE-011-ASSIGNMENT-*, SRE-011-OUTCOME-*, SRE-011-COMMIT-*, SRE-011-REPLAY-*, and SRE-011-HANDOFF-*.

Implementation status (2026-08-04): Contract 011 is implemented and verified as a fixture-profile-driven in-memory ordering slice documented in docs/Evidence/CONTRACT_011_CANONICAL_ORDERING_EVIDENCE.md. It consumes exact normalized element and relationship identities, uses explicit relationship bridges, scopes, constraints, graph/application/linearization evidence, ordering decisions, and assignments, and publishes the exact immutable input consumed by Contract 012.

Contract 012 — Structural Validation

  • Governing question / owned act: Evaluate structural conformance and construction eligibility without mutation or semantic resolution.
  • Principal success / failure publications: StructuralValidationResult; StructuralValidationFailureRecord.
  • Current readiness / disposition: IMPLEMENTED — VERIFIED WITH DECLARED FIXTURE PROFILE, CONSTRUCTION-REQUIREMENT, SCHEMA, REGISTRY, RULE-SET, IDENTITY, REPLAY, AND PERSISTENCE DEPENDENCIES.
  • Observability findings: Eligible, EligibleWithWarnings, Ineligible, Deferred, completion state, findings, decisions, and operation failure are explicitly distinct. Ineligible is a completed result; unresolved rule/schema/registry conditions are not silently converted into deferred eligibility.
  • Internal mechanisms: Rule evaluator, ordering, aggregation, and storage may vary under equivalent findings and top-level results.
  • Observable decisions already governed: No repair, mutation, reordering, semantic resolution, or construction; exact ordered-input binding; deterministic rule application and atomic outcome.
  • Authorized dependencies: Validation Profile, schemas, structural registries, rule sets, and Construction Requirements with required identity/version binding.
  • Mixed decomposition: Eligibility semantics and findings are observable; rule execution engine and persistence are internal.

  • Observability findings: Exact ordered/validation binding, mechanical-only decisions, authorized omissions, inseparable artifact/manifest publication, immutable identity, correction by new operation, and exactly one terminal outcome are explicit.
  • Internal mechanisms: Builder layout, mapping code, intermediate values, and physical multi-write transaction may vary if the constitutional publication set is equivalent and atomic at the constitutional level.

  • Authorized dependencies: Construction Profile, Construction Schema, validation result, rule-set/registry/configuration/version bindings.
  • Mixed decomposition: Mechanical assembly algorithm is internal; exact field/reference mapping, omissions, publication grouping, and identity are observable and profile/schema governed.
  • Specification gaps: None identified in this audit; production construction authorities, broader schema coverage, durable persistence, and production conformance remain declared limitations.
  • Boundaries / repair: Contract 014 owns issuance identity and standing; no repair required.
  • Evidence: docs/Evidence/CONTRACT_013_CANONICAL_REQUEST_CONSTRUCTION_EVIDENCE.md, 15 focused Contract 013 tests, exact dual-input binding, atomic request/manifest publication, and replay verification.

Contract 014 — Canonical Request Identity and Issuance

  • Governing question / owned act: Assign deterministic issued identity and initial standing to one exact Construction Publication Set.
  • Principal success / failure publications: Inseparable CanonicalStructuredRequest plus IssuanceManifest; IssuanceFailureRecord.
  • Current readiness / disposition: IMPLEMENTED — VERIFIED WITH DECLARED FIXTURE PROFILE, POLICY, REGISTRY, REPLAY, AND PERSISTENCE DEPENDENCIES.
  • Observability findings: Fixture-bounded exact construction binding, declared policy-selected identity inputs, deterministic derivation, replay, context distinction, initial Issued standing, immutable pair publication, and lifecycle prohibitions are verified.
  • Internal mechanisms: Identity derivation implementation, indexes, sequence allocator, digest library, and persistence may vary only after identity-bearing inputs and algorithms are declared by policy/profile.
  • Observable decisions already governed: Initial issuance only; no supersession, replacement, renewal, correction, revocation, suspension, expiration, withdrawal, or lifecycle reissuance authority.
  • Authorized dependencies: Identity Policy, Issuance Profile, rule set, registries, serialization/digest and version bindings. Event-unique issuance is permitted only when expressly declared by Identity Policy.
  • Mixed decomposition: Identity semantics and exact bindings are observable; identifier algorithm implementation is internal once policy authority is complete.
  • Specification gaps: None identified after the prior authority-boundary repair.
  • Implementation status (2026-08-04): CONTRACT 014: VERIFIED WITH DECLARED FIXTURE PROFILE, POLICY, REGISTRY, REPLAY, AND PERSISTENCE DEPENDENCIES. The bounded runtime derives deterministic identity from declared policy-selected inputs, assigns only initial Issued standing, and atomically publishes the issued request and issuance manifest from one exact Contract 013 pair. Evidence: docs/Evidence/CONTRACT_014_CANONICAL_IDENTITY_AND_ISSUANCE_EVIDENCE.md.
  • Boundaries / repair: No later lifecycle authority is invented. No repair required.
  • Evidence: SRE-014-DOCTRINE-005–015, SRE-014-POLICY-*, replay clauses, SRE-014-PUBLICATION-*, SRE-014-COMMIT-*, and lifecycle exclusions.

  • Observability findings: Fixture-bounded exact Issuance Publication Set binding, active Downstream Boundary Declaration, Handoff Context, reference-only package manifest, attempts, recipient-attributable acknowledgment, non-authoritative rule applications, separate custody/responsibility decisions, negative outcomes, retry continuity, duplicate correlation, expiration, and terminal alternatives are verified.
  • Internal mechanisms: Transport, adapter, queue/storage, retry engine, and acknowledgment-verification implementation may vary when exact artifact binding and terminal dispositions remain equivalent.
  • Observable decisions already governed: Receipt is not approval; endpoint is not boundary identity; sender cannot fabricate acknowledgment; custody differs from responsibility; handoff does not authorize execution.
  • Authorized dependencies: DownstreamBoundaryDeclaration, HandoffProfile, Transfer Rules, acknowledgment/boundary/disposition/custody/responsibility/status registries, and exact version bindings.
  • Mixed decomposition: Transport mechanism is internal; recipient identity, attempt/acknowledgment attribution, custody/responsibility, and terminal outcome are observable and profile governed.
  • Specification gaps: None identified in this audit.
  • Implementation status (2026-08-04): CONTRACT 015: VERIFIED WITH DECLARED FIXTURE PROFILE, BOUNDARY, RULE, REGISTRY, REPLAY, AND PERSISTENCE DEPENDENCIES. The bounded runtime publishes one terminal completed account or failure and introduces no downstream authority. Evidence: docs/Evidence/CONTRACT_015_CANONICAL_REQUEST_HANDOFF_EVIDENCE.md.
  • Verification correction: The completed Contract 015 slice has 35 focused tests in contract_015_tests; the evidence record is authoritative for the final test count.
  • Boundaries / repair: Downstream intake and lifecycle authority remain with the recipient system; no repair required.
  • Evidence: SRE-015-DOCTRINE-005–024, SRE-015-PROFILE-*, SRE-015-OUTCOME-*, SRE-015-FAILURE-*, and SRE-015-COMMIT-*.

Audit conclusion for Contracts 002–015

  • Genuine specification gaps: None identified in Contracts 001, 010, or 011 after their authorized narrow repairs.
  • Lawful but unresolved profile/policy dependencies: Contracts 002–009 and 012–015 require their expressly authorized profiles, policies, schemas, registries, and rule sets to be identified, version-bound, and available before implementation. Contract 001’s Composite Admission Policy repair is now present; its default behavior is defined.
  • Safe internal decisions: Module/crate layout, storage technology, indexes, caches, graph/ordering/replay algorithms, and transport mechanisms may vary only when all governed artifacts, states, identities, bindings, and replay outcomes remain equivalent.
  • Mixed decisions: Identity versus derivation, commitment versus storage/recovery, replay equivalence versus replay engine, registry semantics versus lookup/storage, profile applicability versus resolver, integrity boundary versus digest implementation, time semantics versus clock implementation, and handoff semantics versus transport are bounded by the Decision Register’s observability classifications.
  • Earliest implementation after repair: Contract 001 is the earliest bounded runtime candidate; Contracts 002–009 may follow their profile dependencies. Contracts 010 and 011 are no longer specification-blocked and may be implemented when their declared profile/registry/rule/schema/evidence dependencies are bound; downstream Contracts 012–015 remain dependency-ordered behind them.
  • Contracts 000–001 pause: Contract 001’s prior gap is closed by the authorized repair. Family implementation remains paused until the Contract 001 profile/default evidence and the later profile dependencies are formally mapped; no contract status is promoted here.
  • Later independent implementation: No later contract may be implemented independently in a way that bypasses dependency order or invents observable normalization/order semantics; repaired terminal models remain the governing boundary.
  • Plan/architecture discrepancy: The adopted plan’s broader lifecycle language for Contract 014 remains subordinate to the repaired/frozen initial-issuance boundary. SRE-ARCH-003 remains provisional and non-binding.
