## Notable commits

- fix: fix!: the merge review's defects on main, each pinned by a matrix (#2499)
- fix: fix(core)!: redact resolved credentials and encoded request diagnostics (#2546)
- fix: fix(core): restore the observe scrub helpers; a truncated stream is retryable (#2502)
- fix: fix(gemini, rig-ecs): retry transient provider failures inside the run; block_reason=OTHER is not a refusal (#2500)
- fix: fix(rig-cassette): restore start_at and checkpoint_recording for consumers that stage candidates (#2498)
- fix: fix(rig-ecs): a Retry written on an empty turn asks again instead of settling (#2504)
- fix: fix: Responses strict:false, Anthropic 128k/Claude 5, and stale Groq/Moonshot/Ollama constants (#2530)
- fix: fix: honour the WASM bounds in every vector store (#2545)
- fix: fix: lenient Responses metadata decode (top_p) and valid rig-postgres search SQL (#2531)
- fix: fix: publish the facade, not the repository — and stop asking for dependencies nothing uses (#2563)
- fix: fix: recover from malformed streamed tool arguments, preserve Responses compaction/phase, drop the tool_macro alias (#2532)
- fix: fix: repair eleven downstream consumer conformance defects (#2561)
- fix: fix: the parity gaps the ECS matrices found, closed — Gemini's block is a refusal, a truncated reasoning-only turn commits nothing, images ride the regrouped stream (#2509) (#2510)
- fix: test(cassette): guard history round-trips and fix Groq and Ollama replay (#2576)
- change: Reduce test-suite compilation and duplicated fixtures (#2518)
- change: Revise agent guidelines and error handling rules (#2533)
- change: Unify every provider onto one wire model (#2538)
- change: chore(cassette): make rig-cassette publishable (#2497)
- change: chore: faster local iteration (lean dev profile, local nextest profile) (#2610)
- change: ci: the slow lanes run off the queue and on main; the ECS parity goldens as a named lane (#2508)
