Purpose

Document 2026-07-06 deep-analysis findings + author the swarm remediation/execution plan (waves, briefs, gates, tracking)

Work log

• Wave 0 executed: 5 scoped commits — map wiring 5803cef6, runner-ceiling docs 043dd93e, zed 7d6fc9be, roster+skills tracked w/ context-safety 06e964ff (BONUS: .gitignore was hiding the whole roster from git), plan docs b2fb39e1 at 2026-07-05 23:03
• PAUSE POINT (limit resets 14:00 UTC): 6 agents in flight when paused — W3.4 DI shrink (container+SPEC-024+checker rule, late stage), W5.2a spec-102 stamps (harness), workflow_engine resolver (SPEC-014 restamp+delete, test_kernel cleanup in progress), W4.3a architect tool-loop, W4.4 injector merge (inject_for_task taking shape), W8.1 context-layer inventory (read-only) at 2026-07-06 01:21 Details:
  • RESUME CHECKLIST: (1) check task notifications for landings/casualties; (2) git status — commit landed work per-task scoped; (3) relaunch any rate-limit casualties with same briefs (they are in the transcript); (4) reconcile check-traces total (~330 falling) + ratchet check-traces and pyright gates to new floor; (5) run ast-sync (snapshot stale); (6) full-suite verification (scripts/run_tests.py); (7) then W3.1 absorption, W4.3b/c, W5.3 tail + SPEC-028 sentinel, Wave 6, Wave 7 incus dogfood, Wave 8 design (W8.2 after inventory, per D11 deterministic selection)
• BATCH FULLY LANDED (8/8 agents + finisher work): commits e0691d33 (SPEC-014 restamps), c01d045e (W3.4 DI), 6bdd355b (T3 fix), e8a9a492 (W4.4 merge), ab920ad9 (D9 call-site wire-up), 07bc9eec (W4.3a architect tool loop), 0c57cd46/d674d816 (99 stamps), e4f4ab6e (gates ratcheted: check-traces 373->293, pyright 631->598; plan checkboxes flipped). AST snapshot refreshed. Launched pre-reset: harness-gate-fix wirer (scenario method key + cli main guard + history auth) + W5.3 tail auditor (read-only). Reset monitor armed 06:40 UTC at 2026-07-06 01:40
• Pre-reset window closed out: harness gate fixed 3150ba02 (cxp_inject scenario, CLI main guard, Neo4j empty-password root cause + .env fallback; 4 pre-existing defects filed incl. architect/qa init stubs + executor packet-contract mismatch + evaluator worktree blindness; D8 gate ADJUSTED until Wave 7 infra). W5.3 stamps + full fake-traces purge committed 8d2ef63d + e64e4230 (detector.py now honest, 13 fakes gone). Wave 5 FULLY CLOSED. Launched W4.3b CodeDirector tool-loop (D8 stage 2). check-traces 290, pyright 598. Reset monitor 06:40 UTC at 2026-07-06 02:15
• W4.3b committed: CodeDirector self-review through tool loop (D8 stage 2/3); test-file type debt 7->0 folded in. Next: W4.3c Qa volk, then W3.1 absorption. Junior._call_design_review_llm filed as candidate at 2026-07-06 02:33
• W4.3c committed — D8 COMPLETE (Ar/Cd/Qa all through tool loop; persona-composition omission caught+regression-tested). Wave 4 fully closed. W3.1-exec in flight (checkpoint+KG absorption). Remaining: escalation design pass, Wave 6, checklist extensions, Wave 7 dogfood, Wave 8 design at 2026-07-06 03:10
• DEBT BATCH FULLY LANDED + gates ratcheted (2e5b16a5): pyright 631->283 session-total (-348; sweeps: session 165->0 w/ 3 real bugs, qa mixins 78->0, kernel managers 69->0 w/ latent dispatch bug, toolkit 46->0 w/ match_case crash fix, cxp grpc 2 production bugs); check-traces 373->236; W3.1 absorption committed 23301677 (checkpoint REAL, resume REAL, KG mixin shared); W6.1/2/3/5 all committed; no-stash + no-background-gates now standing rules. Full suite verification running. REMAINING: escalation design pass, spec-001 renumbering, W6 tail items, Wave 7 incus dogfood, Wave 8 design at 2026-07-06 05:01
• Threadpool-runner forensics validated at small scale: (1) 2-module batch with 40s ceiling reproduced the mass-failure exactly — batch killed at 40.7s, fast module reported FAILED alongside the slow one with identical shared blob (timeout kill -> no junit -> whole batch failed); (2) permanent regression test tests/core/test_worker_neo4j_mapping.py proves gw0->default/.11, gw1->.13, gw2->.14, gw7->fallback each with live bolt round-trip; (3) runner now surfaces 'batch error: Timeout after Ns' above the blob (e8a1053d). Full suite run 5 relaunched with per-worker instances + 2100s budget at 2026-07-06 06:22
• LadybugDB spike executed (user-directed): mechanics excellent (0.05s startup, PK enforcement, Neo4j-matching null order) but disqualified for the test fleet — single-writer per DB kills parallel-writer tests, schema-first kills ad-hoc test_id labels, 5/5 Neo4j-Cypher probes fail, no 3.14t wheel, 443MB RSS. Research doc updated + committed; Neo4j-clone fleet ruling now evidence-backed at 2026-07-06 07:23
• neo4j-node-4 provisioned at .19 — collision post-mortem: cloning the RUNNING neo4j-db copies /etc/systemd/network/eth0.network with static Address=10.92.53.11 (netplan is empty — wrong place to look); machine-id wipe insufficient; the fix is exactly the user's original directive: rewrite the clone's network config file per instance. node-2/3 have NO static file (DHCP + incus reservation), node-4 now static .19. Fleet: .11 prod + .13/.14/.19 clones, all bolt-verified at 2026-07-06 07:51

Artifacts

• plans/analysis-2026-07-06-findings.md - plans/swarm-remediation-plan-2026-07-06.md - plans/research-oss-graph-alternatives-2026-07-06.md - Complete OSS graph-DB alternatives research: survey + 4-engine deep-dive + first-party LadybugDB spike + recommendation (stay on Neo4j CE; ArcadeDB escape hatch; re-evaluate 2026-11)

Decisions

• Roster + skills now tracked in git (.gitignore whitelist for .claude/agents + .claude/skills): plans/agent-roster.md declares the repo the source of truth but the .claude/* ignore rule kept agents/skills out of git entirely — silent single-copy risk at 2026-07-05 23:03
• Neo4j test scaling = 3-4 STANDALONE Community server instances (separate incus containers/ports/data dirs), NO clustering/replication/coordination; batched-runner worker groups map 1:1 to instances via the existing gwN conftest seam (gw0->:7687, gw1->:7688, ...); sized to the runner's -j 4 default: User directive: no neo4j cluster — just run groups of tests against 3-4 independent server instances at 2026-07-06 05:57
• Test-instance engine stays Neo4j Community (clones) — engine parity with production, zero Cypher-porting risk. Memgraph noted as benchmarked fallback ONLY if instance RAM becomes the constraint (Bolt-compatible, ~100-200MB vs ~1GB JVM, but Neo4j-5 constraint DDL + some functions diverge => test-vs-prod engine split is a soft mocking problem). Neptune ruled out for local tests: AWS-managed only, no self-host, openCypher dialect without Neo4j constraints: User raised Neptune + Memgraph as alternatives during the Neo4j test-scaling discussion at 2026-07-06 05:59
• Suite wall-clock target: <5 min (user goal). Requires all three: (1) -j 12 with instance fleet (parallelism math: ~52 worker-min / 12 ≈ 4.3 min); (2) split test_pipeline_e2e.py into per-work-type modules — at 6.5 min it alone exceeds the target regardless of workers; slowest-single-test floor then ~148s LLM latency; durations sweep for other >2min modules; (3) batches > workers in the executor (e.g. 48 batches / 12 slots) for packing + smaller timeout blast-radius: User set the 5-minute goal for the scaling ladder at 2026-07-06 06:34

Achievements

• FIRST fully green full suite post-absorption: run 7 = 1106 modules, 0 batch deaths (segfault fixed by 3.14.6t, timeout by 2100s budget + per-worker Neo4j, collection kill by declaring aiohttp), 2 stale-test failures fixed and verified. Failure-mode ledger closed: 5 distinct root causes across runs 3-7, all fixed at root
• First fully green suite post-absorption: 21,918 tests passed / 0 failed / 1 skipped, 1113/1113 modules, 8m03s, 70.5% coverage — via 4-instance tmpfs Neo4j fleet, work-stealing batches (8x3), executor attribution/kill fixes, grpc leak fix
