checkpoint: matrix-agent-validated (2026-04-25)

Architectural snapshot of the lakehouse codebase at the point where the
full matrix-driven agent loop with Mem0 versioning + deletion was
validated end-to-end.

WHAT THIS REPO IS
A clean single-commit snapshot of the lakehouse code. Heavy test data
(.parquet datasets, vector indexes) excluded — see REPLICATION.md for
regen path. Full lakehouse history at git.agentview.dev/profit/lakehouse.

WHAT WAS PROVEN
- Vector retrieval across multi-corpora matrix (chicago_permits + entity
  briefs + sec_tickers + distilled procedural + llm_team runs)
- Observer hand-review (cloud + heuristic fallback) gating each candidate
- Local-model agent loop (qwen3.5:latest) with tool use + scratchpad
- Playbook seal on success → next-iter retrieval surfaces it as preamble
- Mem0 versioning + deletion in pathway_memory:
    * UPSERT: ADD on new workflow, UPDATE bumps replay_count on identical
    * REVISE: chains versions, parent.superseded_at + superseded_by stamped
    * RETIRE: marks specific trace retired with reason, excluded from retrieval
    * HISTORY: walks chain root→tip, cycle-safe

KEY DIRECTORIES
- crates/vectord/src/pathway_memory.rs — Mem0 ops live here
- crates/vectord/src/playbook_memory.rs — original Mem0 reference
- tests/agent_test/ — local-model agent harness + PRD + session archives
- scripts/dump_raw_corpus.sh — MinIO bucket dump (raw test corpus)
- scripts/vectorize_raw_corpus.ts — corpus → vector indexes
- scripts/analyze_chicago_contracts.ts — real inference pipeline
- scripts/seal_agent_playbook.ts — Mem0 upsert from agent traces

Replication: see REPLICATION.md for Debian 13 clean install + cloud-only
adaptation (no local Ollama).
