v26.6.19

RLM reliability fixes + tuning levers

This release hardens the RLM answer engine so it can no longer return a silent empty answer, and adds two opt-in levers for hard questions.

Fixed

• Empty-answer bug. When the CodeAct loop exhausted its iteration budget without calling final(), it returned an empty string flagged as a valid answer (no_answer=false) that callers could not detect. A blank result is now surfaced as no_answer=true with an explanatory note, and the out-of-iterations fallback re-asks the model with no tools so a diverged run must emit text instead of nothing.

Added

• CodeAct turn logging + convergence warnings — per-turn DEBUG trace and a WARNING when the loop exhausts its budget without converging.
• Per-request extended_reasoning (AnswerRequest.extended_reasoning, default false) — runs the engine at twice the configured FLYCANON_RLM_MAX_ITERS for a single hard request, without a global default bump. RAG ignores it.
• Self-consistency guard (FLYCANON_RLM_SELF_CONSISTENCY, default 1 = off) — when >1, the non-streaming answer path runs the engine N times in parallel and an LLM selector returns the most-grounded answer; token usage of all runs + the selector is merged.

Changed

• Scoped RLM system prompt — requires verifying every benchmark/threshold/figure against the source documents and forbids stating a value not found in them.

Build

• boto3 is now declared in the dev extra so the S3 object-store backend's unit tests and the pyright type-check of storage/s3.py run deterministically in CI (they previously relied on a transitive path that went away).
