v3.10.43 — Fable 5 / Opus 4.x temperature fix, daemon TTL, federation cap

Patch release bundling four bug fixes landed since 3.10.42.

Fixes

#2358 — agent_execute 400s every current frontier Anthropic model (HIGH)

callAnthropicMessages() always sent temperature (default 0.7), but Fable 5, Opus 4.8, and Opus 4.7 removed temperature / top_p / top_k. Every request returned 400 invalid_request_error: temperature: Extra inputs are not permitted. Invisible on Claude-Max (no key → provider check short-circuits before fetch); fatal on a raw ANTHROPIC_API_KEY. New modelRejectsSamplingParams(model) predicate gates the field; Sonnet 4.6 / Haiku 4.5 / Opus ≤ 4.6 unchanged. Closes #2357 Finding A.

#2365 — OpenRouter slugs refreshed to current 4.x family

The OpenAI-compat path still referenced the Oct-2025 retired model IDs:

• default model: anthropic/claude-3.5-sonnet → anthropic/claude-sonnet-4-6
• haiku alias: anthropic/claude-3.5-haiku → anthropic/claude-haiku-4-5
• sonnet/inherit alias: anthropic/claude-3.5-sonnet → anthropic/claude-sonnet-4-6
• opus alias: anthropic/claude-3-opus → anthropic/claude-opus-4-8

OPENROUTER_DEFAULT_MODEL still wins for callers who want to pin a specific slug. Closes #2357 Finding C.

#2361 — daemon self-terminating TTL + global status + HNSW/init footguns

Community PR by @shaal addressing @pacphi's ruflo-machine-ref investigation. The daemon used to run interval workers (audit ~30m, optimize/testgaps ~60m, …) forever, each spawning a headless claude --print sweep. Audited evidence traced a Max-plan quota burned in 1–2 days to 6 immortal daemons (oldest 19 days) and a recurrence to 17 per-project daemons (34,533 total worker runs — ~94% of token spend was background machinery). This release adds: self-terminating TTL, idle shutdown, daemon status --all (global, not just current workspace), honest HNSW reporting, init footgun guards. Closes #2360.

#2364 — federation plugin: cap agentic-flow peer to <2.0.13

Upstream agentic-flow@2.0.13 dropped the ./transport/loader subpath. Runtime impact was bounded — midstream-aware-loader.ts wraps the dynamic import in try/catch and falls back to midstream-native — but the peer range previously said >=2.0.12-fix.8 and silently accepted 2.0.13. Tightened to >=2.0.12-fix.8 <2.0.13 so npm install warns about the incompat instead of hiding it behind a silent fallback.

Still open from #2357

• Finding B (Fable routing tier RFC, PR #2359) — behavior-neutral, 21/21 tests green, awaiting maintainer decision before the June 22 Max-plan API-credits window. Review comment on the PR lays out the three design calls.

Install / upgrade

npx ruflo@latest init        # 3.10.43
npx @claude-flow/cli@latest  # 3.10.43

All three packages (@claude-flow/cli, claude-flow, ruflo) and all three dist-tags (latest, alpha, v3alpha) verified at 3.10.43.
