…sational services (#149)

- ConversationalActionEvidence schema: binds conversation session/turn to AgentPlane
  execution artifact — action_type (8-value enum), policy_decision_ref, execution_artifact_ref,
  replay_linkage (eligible/verified/divergence_detected/scope), hellgraph_evidence_refs
- ConversationalReplayRecord schema: replay artifact for conversational triggers — status
  (completed/failed/diverged/pending), replay_scope (turn/session/execution_artifact),
  divergence_record (conditional required when status=diverged) with divergence_type
  and resolution_status enums, non_claims required
- Policy gates: approval_denial forces deny/escalate outcome; replay_divergence_detected
  requires replay_divergence_ref; diverged status requires divergence_record
- 4 valid fixtures (trigger-execution, approval-denial, replay-completed, replay-diverged)
  + 2 reject fixtures
- validate-conversational-evidence wired into Makefile aggregate validate target

…cybernetic oversteer controls (#136)

- docs/doctrine/tensegrity-runtime-contract.md: compression members (agent/tool/service/model/repo/host)
  vs tension members (policy/identity/provenance/tests/signatures/audits/ledgers/capability_grants/replay/revocation)
  and five tensegrity invariants: policy always required, closed chain, revocation dissolves immediately,
  replay seals the loop, oversteer is a governance obligation
- docs/specs/agent-action-tension-members-v0.md: tension member obligations matrix by action type;
  structural rules (policy always required, replay for mutation actions, audit for blocked/intervention,
  revocation path at R2+, provenance must include upstream anchor)
- docs/specs/capability-radius-v0.md: R0 observe-local through R5 deployment-host-mutation;
  radius/tool-grant contract; rapid_radius_escalation oversteer indicator
- docs/specs/cybernetic-oversteer-v0.md: 10 oversteer indicators with tension member under strain mapping;
  detection contract (HellGraph emission, delivery_excellence degraded, escalate elevation, RationalGRL softgoal);
  oversteer vs. error distinction
- examples/tensegrity/agent-action-tension-members.example.json: full tension member declaration for R3 write
- examples/reachability/agent-capability-radius.example.json: R3 actor profile with conditional R4 gate
- examples/governance/oversteer-indicators.example.json: policy_flip_flops + repeated_failed_validations
  simultaneous firing → escalate elevation + delivery excellence degraded signal

…with replay semantics (#134)

- ConceptToArtifactLineageReceipt schema: concept_kind (10-value enum: term/definition/geometry_relation/
  projection_relation/scenario/prototype/artifact/commons_impact_claim/dymaxion_metric_claim/cross_reference),
  source_anchor (type/confidence/assumptions), geometry_projection with mandatory distortion_assumptions,
  artifact_linkage with lineage_chain_refs, commons_impact with evidence_basis enum,
  dymaxion_metric with required assumptions
- extraction_mode 4-value enum: deterministic_extraction → exact replay; model_assisted → near_equivalent;
  human_review → indicative_only; non_replayable_interpretive_judgment → not_replayable
- Policy gates: non_replayable mode forces is_replayable=false + non_replayable_reason required;
  distortion_assumptions and dymaxion_metric.assumptions must be non-empty; asserted_without_evidence
  commons claims cannot be peer_reviewed; non_claims required on all receipts
- 3 valid fixtures: Dymaxion artifact lineage (model_assisted), geodesic projection claim (human_review),
  interpretive judgment (non_replayable) + 2 reject fixtures
- validate-concept-to-artifact-lineage wired into Makefile aggregate validate target
- Integration targets: ontogenesis#61, gaia-world-model#21, sherlock-search#42, sociosphere#291

…ecution artifacts (#119)

- ModelRoutingLaneDecisionReceipt schema: run_ref, chain_stage (planning/execution/verification/
  reflection/synthesis), task_class (8 values), requested_lane, selected_lane (5 lanes: no_model through pro),
  lane_decision_outcome (lane_selected/downgraded/escalated/denied/deferred), cost_class, prompt_evidence_policy
  (hash_only default — raw prompts never stored), context_tool_posture, verification_mode
- High-end/pro conditional: selected_lane=high_end or pro requires escalation_receipt_ref +
  de_escalation_required_after_stage (schema conditional allOf)
- Policy gates: denied outcome must de-escalate to no_model; verification stage must not use
  model_primary; high-end without escalation_receipt → denied; no raw prompts enforced
- 4 valid fixtures: standard lane_selected, escalated high_end with receipt+de-escalation, verification
  no_model mechanical_tools_only, denied high_end without escalation de-escalated to no_model
- 2 reject fixtures
- validate-model-routing-lane-receipts wired into Makefile aggregate validate target
- Consumers: model-router (AgentExecutionModelRoutingPolicy), guardrail-fabric integration

- SHIRGovernedChainJob schema: job_type const (shir.governed_chain.v0.1), 4 required inputs
  (input_ref, schema_ref, ontology_profile_ref, out_ref), policy_mode (advisory/fail_closed/review_required),
  relation_strategy (default relation_node), all 4 stages (rdf_to_shir/shir_to_pyg/semantic_leakage/chain_receipt),
  full artifact manifest (11 artifact refs), 8 failure modes
- job_status conditional: requires_review/failed_closed require failure_mode + policy_outcome
- Policy gates: fail_closed + semantic_leakage_blocking → failed_closed; completed requires chain_receipt
  completed; shir_to_pyg completed requires projection_loss_report_ref
- 2 valid fixtures: clean TopoLVM run (allowed) + leakage review_required (semantic_leakage_blocking)
- 2 reject fixtures: wrong job_type const, requires_review without failure_mode
- validate-shir-governed-chain-job wired into Makefile aggregate validate target
- Non-goals enforced: no tensor materialization, no GNN training, no ontology promotion, no PyTorch/PyG/DGL
- Upstream: mlops-ts-suite#36-39, #45, #46
