Compact Summary - 3-Lang Depth PropGraph Unification - 2026-07-06

Branch: feat/3lang-depth-proposition-graph-unification
Top commit: 29284fae feat: implement phases 1-5 3-lang depth unification (antiunif root, default depth, contemplation prop, graph helper)
Working tree: Dirty (feature + cleanup). See git status below.

Key touched (feature): pack_resolver (DEPTH_PACKS), runtime/pipeline (depth wiring + oov context), anti_unifier + new depth_canonical (root-aware), graph_planner (depth fields + get_node_depths), contemplation/pass_manager + problem_frame_contracts (propagation), realizer-adjacent.

Work Status

• Phases 1-5 COMPLETE for 3-lang (en/he/grc) depth on PropGraph spine (see plan.md for details).
  • Root-aware anti-unif (nid-keyed, no proxy).
  • Default node_depths in pipeline/oov.
  • Depth propagation (runtime → teaching/contemplation → generate/pass_manager/contracts, immutable).
  • Graph helpers (graph_anti_unify, PropositionGraph.get_node_depths()).
  • Real tests + evidence (non-empty 3lang ctx/root from "define אמת", id matches, fresh trace stable, etc.).
• Verification (latest):
  • Cognition: 122 passed, 1 skipped.
  • Spine tests (anti/depth/pipeline/graph/contemplate): green.
  • Broad (oov|anti|prop|realizer): 524 passed.
  • verify_lane_shas.py: 7/9 match. Only demo_composition + public_demo drifted (intentional — touched listed files; re-pin later).
  • Fresh trace on Hebrew OOV: stable.
• plan.md is current (includes post-impl verification + SHA watch items).

Changes & Why

Intentional: add language/root/depth to PropGraph so it travels the cognitive path for hebrew_greek_textual_reasoning (and 3-lang in general).

This changes outputs captured by demo lanes → expected SHA drifts.

Core remains stable (trace on fresh, cognition lanes, other pinned SHAs).

Watch Items (from verification)

• demo_composition + public_demo SHA drifts (expected/intentional from spine changes).
  • Re-pin: python scripts/verify_lane_shas.py --update && python scripts/generate_claims.py when current active slice done or pre-PR.
  • Monitor: run verify after any output-affecting change.
• Fresh trace_hash stability on 3-lang OOV cases.
• hebrew_greek domain (already reasoning-capable, 0 gaps) — this work makes it real.

No other issues. No core regression.

New-Session Quick Start

1. git status --porcelain -b; git log --oneline -1
2. python3 scripts/verify_lane_shas.py
3. python -m pytest -q --tb=no -k "cognition or oov or anti_unifier or depth_canonical or graph_anti"
4. Fresh trace spot-check (see COMPACT_STRATEGY.md for the one-liner).
5. Read: AGENTS.md (Session Continuity), plan.md, this compact.

Next R&D

• Continue the current active part of the unification.
• Shape around: core lanes stay green, depth effects visible/traceable in 3-lang, document intentional demo changes.
• When slice feels done: re-pin + claims, then PR.

Key Files

• plan.md (living plan + evidence)
• docs/COMPACT_STRATEGY.md (process)
• docs/session-compacts/ (this file)
• tests/test_oov_pipeline.py + construction tests
• scripts/capture_spine_evidence.sh + scratch logs

Invariants

• Fresh trace stable on 3-lang.
• Core + spine tests green.
• Only expected demo drifts.
• Immutability, no forbidden normalization, exact recall.

Use this + plan.md to seed a new thread. Continue R&D there. Re-pin as part of finishing the slice/PR prep.

(Archive/delete once progressed in new thread.)
