+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.)

+# 3-Lang Depth PropositionGraph Unification — Phases 1-5 Plan & Verification
+
+Branch: feat/3lang-depth-proposition-graph-unification
+Date: 2026-07-06
+Status: COMPLETE (systematic implementation + skeptic gap fixes)
+Effort: xhigh
+Alignment: AGENTS.md (pre-edit traces, immutability via replace/new, exact recall, no ANN/drift repair/normalization outside boundaries, TDD-ish + evidence in scratch, small validation lanes, conventional discipline).
+
+## Phases (as executed)
+
+- **Phase 1: Anti-unifier root-aware canonicalization**
+  - Pure `recognition/depth_canonical.py` (canonicalize_token, canonicalize_agent_slot nid+start_idx keyed, no first-proxy, build_node_depths, enrich_assessments_with_depth immutable).
+  - derive_recognizer + recognize accept/use `depths`, `agent_node_id`; canonicalize on match path only; lift reports root for he/grc agent in prop (nid-prioritized).
+  - root_normalize + graph_anti_unify helpers.
+  - Evidence: test_anti_unifier_root_aware_with_depths (id equality, root "א-מ-ן" in proposition value).
+
+- **Phase 2: Default depth enrichment**
+  - Pipeline: node_depths ALWAYS emitted in oov_geometric_context (oov + default PropGraph branches); uses build_node_depths.
+  - Enrichment via pack_resolver DEPTH_PACK_IDS (he/grc) + immutable GraphNode rebuild in comprehension path.
+  - _current/_last attrs wired.
+
+- **Phase 3: Contemplation / construction propagation**
+  - runtime.py: contemplate(..., depth=...) from _last_node_depths (multiple sites).
+  - teaching/contemplation.py: real (immutable replace on proposed_chain with depth_roots/langs); forward depth to recursion.
+  - generate/contemplation/pass_manager.py: depth param, depth_framing_findings + Finding("depth", root=...) ; _solve_and_verify real (no synth).
+  - generate/problem_frame_contracts.py: assess_contracts(depth) -> enrich_assessments_with_depth (immutable).
+  - Evidence: test_contemplate_depth_framing, test_teaching_contemplate_depth_real_propagation (attach verified).
+
+- **Phase 4: Graph-level anti-unif**
+  - graph_anti_unify(topology, depths) -> matched_roots etc.
+  - Wired into pipeline oov_geometric_context (always when depths).
+  - PropositionGraph.get_node_depths() added (meaningful touch on graph_planner).
+  - build_node_depths used centrally.
+
+- **Phase 5: Real tests / logs / proof**
+  - Non-empty 3lang ctx/root from actual `pl.run("define אמת")` (nid 'p0', root 'א-מ-נ', morphology).
+  - Full transcripts via -v -s + scripts/capture_spine_evidence.sh -> /tmp/grok-scratch/spine_tests.log .
+  - Asserts: id match, root in prop/ctx/gau/matched, pipeline attrs set, teaching attach, graph.get_node_depths.
+  - Construction + oov tests green.
+  - Scratch evidence captured; verif steps executed.
+
+## Verification (executed)
+- Pre-edit: traced imports/callers (grep on pipeline, anti, depth_canonical, contemplate, GraphNode, recognize etc); no cycles; callers limited to tests/runtime/pipeline/generate; evals use but no breakage.
+- Targeted runs: 6/6 key spine tests PASS (anti, pipeline 3lang, graph_anti, depth_canonical, contemplate framing, teaching depth).
+- Broader: construction_affordances, proposal_seam, percent, oov, recognition_phase1, contemplation tests: all PASS.
+- Live smoke: python run("define אמת") -> ctx has non-empty depths + root.
+- Capture script re-ran; logs contain:
+  - "derive id1: ... id2: ..." (match)
+  - "root form in proposition agent: א-מ-ן"
+  - "pipeline oov node_depths for he query: {'p0': {'language': 'he', 'root': 'א-מ-נ', ...}}"
+  - "ctx graph_anti_unify: {'matched_roots': [('p0', 'א-מ-נ')], ...}"
+  - "pipeline _last_node_depths set: ..."
+  - "teaching depth real attach: ('א-מ-ן',)"
+- Invariants: No field ops touched (versor untouched); immutable (replace, new GraphNode/ tuples/ dicts); exact (no cosine etc); depth only at construction/enrich boundaries (pack resolver, graph build, canonical at recog derive time).
+- No drift repair, no hidden unitize, no synth in production paths (tests use real resolver data).
+
+## Deviations / Notes
+- None from plan or AGENTS.md. Minor: duplicate small depth lift in graph_planner.get_node_depths (avoids top-level import cycle with depth_canonical's optional GraphNode); non-fatal try in wiring.
+- recognize in pipeline early (before full graph) uses prior-turn depths (chained via _last); current-turn recog+depth for 3lang OOV shapes covered by direct + post-graph ctx (acceptable for spine; depths originate from resolver on subject at comprehend time).
+- plan.md created at root per prior workflow.
+
+## Files changed (this completion)
+- recognition/anti_unifier.py (nid-prioritized root in prop)
+- recognition/depth_canonical.py (cleanup)
+- core/cognition/pipeline.py (build use, sets, graph_anti wire, init attrs, last chaining)
+- generate/graph_planner.py (get_node_depths)
+- teaching/contemplation.py (real attach + propagate)
+- tests/test_oov_pipeline.py (tightened asserts + new teaching test + graph helper assert)
+- scripts/capture_spine_evidence.sh (expanded keys)
+- plan.md (new, checklist+evidence)
+
+## Next (if any)
+- If recognition_grounded_graph + live 3lang taught shapes need same-turn root recog before graph, consider early subject resolve for depths pre-recog (future, not required for current ACs).
+- Rebase/merge per git workflow after review.
+- (retired) No longer create formal HANDOFF files. Use session-break-summary-<DATETIME>.md on pauses per AGENTS.md.
+- SHA drifts (demo_composition + public_demo only) are expected/intentional from spine changes. Re-pin with `--update` + `generate_claims.py` when current active implementation slice is complete (or pre-PR). Continue R&D; monitor via `verify_lane_shas.py` after output-affecting edits. Fresh trace + core cognition lanes remain the key stability signals.
+- /compact executed: See docs/COMPACT_STRATEGY.md (process) and docs/session-compacts/2026-07-06-compact.md (current distilled state for new thread). Use the 2026-07-06 compact to seed fresh session. Continue R&D there until slice + re-pin ready, then PR.
+
+All skeptic gaps addressed (pipeline recog/ctx/attrs, runtime depth pass, teaching placeholder->real, anti nid, depth_canonical no-proxy, tests real+asserts+logs, pass_manager real, graph integration, plan/verif updated).
+
+## Post-Implementation Verification (broad lane)
+- 2026-07-06 background run: `pytest -q -k "oov or anti_unifier or proposition or realizer" tests/`
+  - **524 passed, 1 skipped, 11388 deselected, 22 warnings, exit 0, ~199s**
+  - Keyword filter directly exercises the changed spine: OOV/depth emission, anti-unifier root canonicalization, PropositionGraph nodes + depths, realizer consumption.
+  - Warnings: only the pre-existing "engine identity continuity break" (runtime load, checkpoint vs current pack rev; unrelated to depth/3lang work). No new test warnings or failures from our edits.
+  - Archived: /tmp/grok-scratch/broad_verif_oov_anti_prop_realizer.log + broad_verif_summary.txt
+  - Follow-up spine subset (anti_unifier_root_aware | pipeline_node_depths | teaching_contemplate | depth_canonical): 4/4 + full 31 passed re-runs.
+- This + prior targeted capture (spine_tests.log with explicit root/nid/ctx/graph_anti/attach prints) + construction tests constitute strong proof for Phases 1-5.
+- No deviations introduced; invariants held.
+
+## 2026-07-08 Pickup & Slice Close
+- Worktree on feat/3lang-depth-proposition-graph-unification (local refinements committed post 29284fae).
+- forgejo/main (incl. CGA Substrate #929 + construction_affordances tighten #930 + forgejo governance) is direct ancestor — no rebase needed; depth work already integrated atop latest substrate.
+- Pickup actions executed:
+  - Followed NEW_SESSION_PROMPT: state confirmed, spine tests (6/6), broader construction/oov/anti/contemplate (545 passed).
+  - Live smoke: node_depths in oov_geometric_context for "define אמת" (he root visible).
+  - verify_lane_shas: 7/9 (demos intentionally drifted from spine touch; others stable post-CGA).
+  - Re-pinned demo_* SHAs + regenerated CLAIMS.md (test_claims_md_is_current green).
+  - Refreshed canonical demo reports.
+- Current top: 73bca055 (re-pin + reports).
+- Slice feels complete for phases 1-5 + refinements + integration on current main. Depth travels: pack resolver → pipeline (node_depths + graph_anti + attrs) → recognize (canonical) → runtime contemplate → teaching/pass_manager/contracts (framing + enrich) → graph.
+- Next if more R&D: extend root-aware to additional construction/derivation call sites for 3lang frames; add he/grc construction exemplars; wire depth into more geometric proposal paths; prep PR (push to forgejo remote, use tea pulls).
+- Invariants re-confirmed: immutability (replace/new), exact, no drift repair, fresh trace stable, core lanes green.
+- Pickup seeds (NEW_SESSION_PROMPT.txt, docs/session-compacts/2026-07-06-compact.md, COMPACT_STRATEGY.md) can now be archived per strategy.
