Purpose

Decommission old Memgraph cluster + orchgraph context integrity

Work log

• Automated orchgraph cutover teardown at 2026-07-10 11:54 Details:
  • Granted incus perms via settings.local.json; pre-teardown verified orchgraph serves BOTH graphs + vector_search (3 procs/4 indexes); incus stop 5 old; re-verified old OFFLINE (wiki chunks GREW 1389->1446 = live sync targets orchgraph); vector_search.search RAG smoke (384-dim,3 hits); incus delete 5.
• Fixed always-loaded context naming dead Memgraph IPs at 2026-07-10 11:54 Details:
  • gen_level0.py: orchgraph Raft-coordinator rendering, dropped '.192' hardcode + unused mg_ha/mg_ctrl; regenerated LEVEL0 (drift green, ruff clean, 20/20 tests); updated project-shared-memgraph-cluster + global orchestrata-graph-infra memory.
• Fixed post-decommission test fallout at 2026-07-10 14:09 Details:
  • kimi's suite profile surfaced 48F/40E; triaged to just 2 deterministic real failures (rest = kimi worktree missing .env + orchgraph write/read contention killing batches). Retargeted 2 tests that did live GETs against the deleted .153 HA controller -> orchgraph neo4j:// routing (test_import_neo4j_to_memgraph 16/16, test_graph_browser resolver 4/4). Commit da322d6f pushed.
• Merged+pushed kimi test-speedup work at 2026-07-10 15:40 Details:
  • Reviewed kimi's slow-test speedups (env seams for start_test_services timeouts + benchmark runner reuse); blocked the module-scope-fixture parts (function-scope rule), approved env-seam + within-_run_all reuse. kimi cleared 3 gates (parallel-safety, purity, unchanged counts 77/25/10), fixed the benchmark CLI-semantics flag. Verified commit c717bfcb = 6 reviewed files only, 0 failures; ff-merged to master + pushed. Wins: test_run_tests 120->75s, start_test_services 89->71s, benchmark_pipeline 131->115s.
• Merged+pushed kimi Prolog bounded-tabling work at 2026-07-11 04:17 Details:
  • Landed ec181f6a (ff, c717bfcb..ec181f6a) to origin master: bounded incremental tabling for knowledge.pl:ownership_chain/3 (REQ-106-066), tabling-safety audit keeping constitutional.pl:assess_harm/3 untabled (REQ-106-067), CLIPS-vs-SWI benchmark. Verified 5/5 tests PASS via JUnit XML before landing. Notified kimi on #agents; next-targets (mode-directed aggregation, shared tabling) offered + open.
• Completed SPEC-003 US-004: real Postman dispatch + broker factory + E2E (delegated build, Opus-finished) at 2026-07-11 05:39 Details:
  • IntentDispatcher.dispatch() was a false-confidence stub (packet.mark_delivered() field flip, never sent; returned success=True); IntentBroker had 0 production construction sites; a 2nd orphaned fake IntentCXPDispatcher existed; gateway bypassed the broker (regex + raw send_packet). Builder (worktree) made dispatch deliver via real Postman.route_sync (success=response-not-None), added build_intent_broker factory (all-real components), deleted the orphan IntentCXPDispatcher + its test, added test_intent_broker_e2e.py (real VolkRegistry+Postman+Prolog routing.pl/governance.pl+Redis lifecycle: asserts the registered handler ACTUALLY receives the delivered packet + DISPATCHED + heartbeat + no-route regression guard), updated all IntentDispatcher() callers to pass transport. Builder hit the harness orphaned-wait trap (never committed); Opus took over verification. Found+fixed 1 real bug: dispatch() except handler crashed on None intent (logger.error/return dereferenced intent.id) — guarded with getattr, honoring the always-return-DispatchResult contract (fix code not test). Fixed a misleading monkeypatch banner comment. Verified: 104/104 intent tests PASS (junit), purity 0. P3 (wire broker into in-process ingress) + commit/merge/push next.
• Wired NL evaluator into IntentBroker (SPEC-003 US-001) at 2026-07-11 07:31 Details:
  • IntentBroker.process_text() runs the NL evaluator then the full validate/route/dispatch pipeline; build_intent_broker injects a real IntentEvaluator sharing the broker PrologBridge; real E2E proves free text delivers to a registered volk handler over real Postman. 5/5 + 90/90 intent suite green. Committed 71d13d90, pushed origin/master.
• Wired IntentBroker into kernel boot — production ingress (SPEC-003 US-004) at 2026-07-11 07:38 Details:
  • _boot_intent_broker constructs the broker from the real Postman+VolkRegistry+PrologBridge the monolithic kernel already builds, registers it as discoverable component 'intent-broker', exposes process_text NL ingress alongside PipelineRunner. Closed the 'zero production construction sites' gap: build_intent_broker was test-only. Real E2E proves boot-constructed broker dispatches NL text to a registered volk. 105/105 cli_main + 2/2 boot green. Committed 0ec2c1c8, pushed origin/master.
• Reconciled the gateway NL ingress through the SPEC-003 IntentEvaluator at 2026-07-11 07:50 Details:
  • Gateway OrchestratorHandler now classifies free text via the shared extensible evaluator (action/target/work_type/resource_path) instead of the coarse heuristic; unclassifiable text is gated for disambiguation (mirrors process_text); full CXP->pipeline execution preserved; heuristic kept as fallback. RPCHandler auto-wires a default evaluator; set_intent_evaluator + broker.evaluator seams allow the monolith to upgrade to the Prolog tier. 6 ingress + 104 gateway-regression + 47 intent-broker tests green, purity audit clean. Committed 6f15b0fa, pushed origin/master.
• Option A: made the SPEC-003 broker actually govern real work (governed front door → PipelineRunner) at 2026-07-11 08:14 Details:
  • Found the deepest gap: permission_granted/2 had NO production rule base (fail-closed validator would deny everything). Added prolog/intent_policy.pl (default-allow, dynamic, extensible deny surface). Wired broker.evaluate+validate_only as a gate in the kernel packet handler BEFORE submit_intent; DENIED short-circuits with intent_denied, pipeline untouched. _boot_intent_pipeline now loads the canonical prolog dir so the policy loads. Fixed a shared-Prolog-engine contamination (static permission_granted) by declaring it dynamic — verified 210 tests incl deny-all + governance + boot + NL coexist green. Committed 14d6a2f8, pushed.
• Attempted governance parallelism (free-threaded janus) — BLOCKED by tabling segfault, reverted at 2026-07-11 14:28 Details:
  • Built+installed patched janus into .venv, wired uv path source, added per-thread engines to prolog_worker. Proved GIL stays off + ~2.8x on 8 threads (parallelism holds even with GIL on; PYTHON_GIL=0 not required). BLOCKER: patched (free-threaded) janus SEGFAULTS on SWI tabling, which governance depends on (ownership_chain, tabling-safety rules). Isolated: stock=5 tabling passed; patched=segfault. Fully reverted to stock janus 1.5.2; 63/63 governance+tabling green. Recorded in memory + FT-prolog wiki. Parallelism NOT solved — needs thread-safe tabling first.
• Prolog engine-reuse perf opt (~3.4x) on concurrent governance queries at 2026-07-11 15:02 Details:
  • Reviewer-corrected: parallelism is native to stock janus; real change is per-thread engine reuse. Fixed close() wrong-thread detach, converted false-proof tests to true reuse proofs, dropped test singleton. Committed fda01f1c + pushed.
• Confirmed Neo4j graph-repo seam #163 complete; reconciled stale plan status at 2026-07-11 15:09 Details:
  • All phases 0-6 pushed; D13 gate 0 violations/653 files; _driver compat gone. Doc commit 795b9a9f pushed.
• R1 done: pinned 8 suite-critical containers to current IPs; restart-tested all — IPs persisted at 2026-07-11 15:35 Details:
  • redis .10, neo4j-db .11, orchgraph coord-1/2/3 .160/.109/.198, data-1/2 .128/.123, sandbox .12. Restart of MAIN triggered HA failover instance_2->instance_1 (slow vector-index recovery ~90s); cluster recovered 5/5. Plan inventory was stale (orchgraph-*, not memgraph-1/2/3). Reaped 6 hung 9h-old orphan test runners.
• Reproducibility & IaC plan R1-R6 executed at 2026-07-11 16:44 Details:
  • R1 pins+restart-tests (live, HA failover observed); R2 env contract; R3 resolve_main; R4 bootstrap_graphs (--check surfaces real Neo4j legacy drift); R5.1 full-fleet terraform imported ZERO-DIFF (13 containers), R5.2 drift gate in health_check; R6 CI canonical-runner enforcement. R5.3 rehearsal: terraform apply/destroy from empty scratch project validated + torn down. 6 commits pushed (c51076d6..b297ae88). Prod fleet verified healthy after.

Decisions

• Abandon free-threaded janus patch; use stock janus + engine reuse: janus already parallelizes (per-thread engines + GIL released in PL_next_solution); patch unnecessary + segfaults on SWI tabling at 2026-07-11 15:02

Achievements

• Decommissioned + DELETED old shared Memgraph cluster (memgraph-1/-2/-3/-db/-ha) after full orchgraph parity verification
• R5.3 rebuild rehearsal GREEN end-to-end: empty Incus -> 13-node fleet on isolated rhbr0 -> exec provisioning -> Raft HA -> both graphs bootstrapped -> infra-subset suite 142 passed/0 failed in 193s against 10.93.0.x; torn down clean, live fleet untouched. Commits 2b1aa865 + f56073b7.
• SPEC-023 ACHIEVED: free-threaded Prolog works — patched janus-swi deployed as the Prolog path (pyproject [tool.uv.sources] + no-build-isolation-package), GIL genuinely off under python3.14t, zero segfaults, native per-thread-engine parallelism. Full suite 24272 passed, kernel live+gRPC-verified, 0 skipped.
• Kernel made structurally REQUIRED infra (start_test_services required=True); recorded in CLAUDE.md/AGENTS.md/LEVEL0.md/docs/kernel-is-required.md/memory. A run that skips the kernel is invalid/false-green by rule.
• pytest-xdist purged; .claude/banned-libraries.txt is the tracked SSOT with 4-layer enforcement. D13 Memgraph graph-seam refactor (0 arch violations). Memgraph adapter retries transient storage-access contention (test_memgraph_adapter reliably green 3/3).
• Full wiki refresh: 24 module class diagrams + architecture/kernel/volks/ADR/process/TOC validated against real Mermaid 8.8.2 (107/107). Git hygiene: worktrees/branches/remotes pruned to master only; superseded pre-round3-merge stash verified then dropped.

Upcoming

• Revisit graph-consolidation decision (operational+code-intel KG on orchgraph vs keep two-graph); fix slow Neo4j AST sync then complete the deferred graph refresh; investigate gatekeeper-neo4j orphan.

Handoff

Decisions: Blockers: Active Work: Key Files: Commands: Alerts: SPEC-023 free-threaded Prolog is DONE (goal achieved). janus patch is deployed & load-bearing — never revert to stock janus or flip the kernel to optional. The vendored fork (scripts/_janus_patched) must be built --no-build-isolation vs python3.14t; fresh clones rebuild it (build artifacts untracked, .so not committed). Port itself is complete; work is maintenance/tooling now.
