Sprint manifest for the NARS Intervention/Counterfactual verbs fleet (first PR in the learning-layer curriculum sequence from PR #373). Per-worker file ownership + wave ordering documented. OQ-LL-1 and OQ-LL-5 autoresolved per "autoattended" directive (graded NARS confidence, clear ICM bit on counterfactual contradiction). Worker outputs land via tee -a AGENT_ORCHESTRATION_LOG + per-agent reports under .claude/board/sprint-log-LL1/agents/agent-W{N}.md. Meta synthesizes after all 6 workers report; commit of .rs changes happens at the meta-review step.
W6 was spawned with the older permission snapshot and hit Edit/Write denials. Main thread backfilled the 4 governance updates per W6's drafted spec: - EPIPHANIES.md PREPEND: E-LL-1-INTERVENE (NARS Intervention/CFG verbs) - AGENT_ORCHESTRATION_LOG.md APPEND: W6 coordination line - knowledge/causal-edge-64-spo-variant.md APPEND: "Recent additions" section linking to PR-LL-1 + curriculum §3.5/§6.1 - sprint-log-LL1/agents/agent-W6.md: agent report (notes the permission-snapshot issue for future agent reference) Future Sprint A wave 2 (W2, W5) and all Sprint B/C waves will have the expanded .claude/settings.local.json allowlist. The 3 modified .rs files (edge.rs, nars_dispatch.rs, triplet_graph.rs) are still in-flight from W1/W3/W4; will commit at meta-review step.
Three of the four wave-1 agents (W1, W3, W4) completed their code
changes but couldn't write their own agent-W{N}.md report files due
to permission snapshots captured pre-expansion. Main thread backfilled
the reports from the agents' task-notification summaries + code diff
inspection.
W1: NarsInferenceType extended with Intervention + Counterfactual,
plus W1 proactively patched 2 downstream exhaustive-match sites
(nars/inference.rs, orchestration_impl.rs) bridging to Abduction.
W3: edge.rs Reserved5/Reserved6 slots renamed to Intervention/
Counterfactual; from_bits decoder updated.
W4: triplet_graph.rs ContextTag enum + CounterfactualSpoG struct +
intervene_on() method.
Workspace cargo check passes. Wave 2 (W2 nars-engine-dispatch + W5
tests-e2e) spawns next with the expanded permissions.
Closes the Pearl 2³ named-but-not-dispatched gap from the neurosymbolic+RLVR+causal curriculum (PR #373 §6.1). Two new NARS inference variants land as first-class verbs in the stack; AriGraph gains an intervene_on() method producing counterfactual SPO-G tagged with ContextTag::Intervention. ## Worker outputs (6 agents + main-thread coordination) W1 — `lance-graph-planner/src/thinking/nars_dispatch.rs`: - NarsInferenceType::Intervention (Pearl rung 2, conf_modifier=0.85) - NarsInferenceType::Counterfactual (Pearl rung 3, conf_modifier=0.70) - Doc comments cite Vashishtha 2025 (arXiv:2510.01539) + ICM - Extended route(), detect_from_query(), confidence_modifier() - Bridged 2 downstream exhaustive-match sites (nars/inference.rs, orchestration_impl.rs) to Abduction semiring as stopgap W2 — `lance-graph-planner/src/cache/nars_engine.rs`: - Local Inference enum: Intervention=7, Counterfactual=8 added - nars_infer() routes Intervention → Abduction × 0.85, Counterfactual → Deduction × 0.70 - New style vectors: intervention_style() weights MASK_PO, counterfactual_style() weights MASK_SPO - inference_to_pearl_mask() + inference_to_style() dispatch helpers - to_causal_edge() updated to map local 7/8 → W3's protocol enum - 4 new tests covering confidence ordering, mask routing, weights, roundtrip W3 — `causal-edge/src/edge.rs`: - Reclaimed Reserved5 → InferenceType::Intervention (slot 5) - Reclaimed Reserved6 → InferenceType::Counterfactual (slot 6) - from_bits() decoder updated - No bit-layout change beyond renaming; binary compat preserved W4 — `lance-graph/src/graph/arigraph/triplet_graph.rs`: - pub enum ContextTag { Observation, Intervention } — SPO-G "G slot" at the AriGraph data layer (raw_g()=0xFF for Intervention) - pub struct CounterfactualSpoG { triplet, context } - TripletGraph::intervene_on(subject, predicate, new_object) — Pearl rung-2 do-calculus, original graph NOT mutated W5 — NEW `lance-graph/tests/intervene_counterfactual.rs` (274 lines): - 8 integration tests covering all 4 worker outputs end-to-end - 7 pass; 1 marked #[ignore] (three_step_counterfactual_chain — depends on abduction substrate wiring, target of PR-LL-4) - clippy::cloned_ref_to_slice_refs fixed in main-thread cleanup W6 — governance (backfilled by main thread due to permission snapshot): - EPIPHANIES.md PREPEND: E-LL-1-INTERVENE entry - AGENT_ORCHESTRATION_LOG.md appended W6 coordination line - knowledge/causal-edge-64-spo-variant.md "Recent additions" section ## Verification - `cargo check --workspace` exits 0 (W1's downstream patches kept it green) - `cargo test -p lance-graph --test intervene_counterfactual` — 7/8 pass (8th #[ignore] for PR-LL-4) - Clippy lint fixed in W5's test (cloned_ref_to_slice_refs) - AGENT_ORCHESTRATION_LOG records all 6 worker entries ## OQ ratifications (autoresolved per "autoattended" directive) - OQ-LL-1: graded NARS confidence ∈ [0,1] (chosen) - OQ-LL-5: clear ICM bit on counterfactual contradiction (deferred to PR-LL-2 where IcmInvarianceColumn lands) ## Predecessor / successor Predecessor: PR #373 (curriculum v1) + PR #372 (causaledge64 substrate) Successor: PR-LL-2 (ICM-invariance column + Opt-Sym generator) consumes the new G slot tagging
