The "magic layer" the wave promises: workers tune their own lease cap based on real upstream signals; failed jobs auto-heal one layer deep for known-recoverable failure modes. Both default ON for fresh installs + upgrades; off-switches per CLAUDE.md. src/core/db-lock.ts — tryWithDbElection convenience (Eng D9) Thin wrapper over the existing tryAcquireDbLock: acquires, runs fn, releases. For per-tick election use cases (controller tick chooses one writer per cluster). Codex pass-3 #8/#9 audit picked this shape over building a parallel new primitive — the existing gbrain_cycle_locks table works for both engines. src/core/minions/lease-cap-controller.ts (E5 reframed + Eng D6 correction) Auto-adapts the rate-lease cap based on bounce rate + upstream 429s + latency stability. CORRECTED control law per codex pass-2 #9: * Ramp DOWN only when upstream pushes back (429s OR latency unstable) * Ramp UP fast when workers starve (bounces > 1/min + no 429s) * Ramp UP slow on healthy headroom (util > 50% + 0 bounces + 0 429s) * Deadband otherwise My first draft had the bounce sign inverted; would have cratered cap during a healthy 100-job burst — exactly the field-report case. IRON- RULE regression test (test/lease-cap-controller.test.ts) pins the correct sign so future "let's simplify" PRs can't silently regress it. Per-tick election via tryWithDbElection — only ONE worker per cluster runs the WRITE side; all workers READ lease_cap_current fresh on every acquire. Asymmetric AIMD steps (rampDown=8, rampUp=4) — TCP congestion control wisdom. Latency signal sourced from subagent job durations in window; full upstream-SDK-latency tracking is v0.42. Pinned by 14 cases including the field-report scenario simulation ("starving workers get MORE capacity, not less"). src/core/minions/self-fix.ts (E6 with narrowed classifier per codex pass-2 #4) Classifier-gated auto-resubmit on terminal failures. ONLY three buckets qualify: prompt_too_long, tool_schema_mismatch, malformed_json. Explicitly NOT recoverable: tool_crash (real bug), tool_unavailable (config issue), tool_permission (needs human). Chain depth cap = 2 (D15 default); per-job opt-out via data.no_self_fix; global off-switch via config. buildSelfFixPrompt cluster-specific prep: prompt_too_long → truncate-with-leaf-preservation (v0.41 ships simple; semantic reduction in v0.42) tool_schema_mismatch → surface error verbatim + "check input_schema" malformed_json → "respond with JSON only — no prose, no fences" Children inherit budget owner from parent (Eng D7 + D10) but DO NOT copy remaining cents (codex pass-3 #5 caught the original plan's contradiction; only owner row holds spendable balance). Pinned by 16 cases. scripts/e5-lease-cap-ab.ts (D11 + codex pass-2 #7 spec) Manually-runnable A/B harness with committed receipt-fixture baseline. Spec: 500 jobs, log-normal prompt distribution, $8 budget per arm, synthetic 429 burst at minute 15, PR-gate verdict (controller must beat fixed-cap by ≥5% on throughput AND match within ±2% on cost efficiency). v0.41 ships the spec + dry-run + fixture shape; real-run dispatcher deferred to v0.41.1 (filed in TODOS).
