release: v1.0.0-rc.3

[matedev01]

Summary

Cuts v1.0.0-rc.3: workspace bump 1.0.0-rc.2 → 1.0.0-rc.3 and a compiled CHANGELOG for the 22 PRs merged since rc.2.

This RC lays the M2 foundations (portable providers + channels), takes deterministic tool-call accuracy to a genuine, CI-enforced 96%, and hardens reliability so one session no longer stalls another.

Highlights

• M2: Provider trait (feat(llm): introduce Provider trait; wrap local model as default (#567) #578) + config-driven selection (feat(provider): config-driven LLM selection + fail-loud validation (#568) #595), Channel boundary (feat(channel): define IncomingTurn/OutgoingResponse boundary and Chan… #573), speaker identity (feat(conv): tag conversation turns with resolved speaker identity and… #560)
• Reliability: conversation (fix(conversation): stop conversation writes from stalling other sessi… #583) and memory (fix(memory): route with_shared_memory through spawn_blocking #606) SQLite moved off the reactor thread; durability + schema tests (Add crash-recovery and concurrent-write durability tests for the memory subsystem #576, test(tools): close #416 memory_forget/memory_store schema enforcement #581)
• Accuracy: genuine live 96.15% (fix(quick-router): produce the rc.2-claimed outputs on the live path #580) now CI-gated against the live router (ci(bfcl): gate the live quick-router, not just the golden file (#579) #594), plus calculator/timer/weather/plural fixes
• Perf: query-diversity batch (perf(memory): batch query-diversity lookup (remove per-candidate N+1) #548), O(n) hydration (perf(memory): make per-turn hydration budget fit linear, not quadratic #585), batched promotions (perf(memory): batch dream-cycle promotions into one MEMORY.md rebuild #586)
• Internals: dispatch (refactor(tools): split dispatch.rs into per-tool modules under tools/dispatch/ (#404) #584) + memory (Split memory/mod.rs derived-table and household-parsing helpers into submodules #604) module splits

Real Behavior Proof

• I have built and run the affected code locally (or noted why I could not).
• I have verified the change end-to-end on Jetson hardware.
• I have NOT verified on Jetson hardware, and I explain the equivalent verification path below.

What I ran

cargo check --workspace   # builds at 1.0.0-rc.3; Cargo.lock updated
cargo fmt --check         # clean

Version + CHANGELOG bump only — no code paths, prompts, or tool behavior change. main was CI-green (CI + aarch64 cross-compile) at the #606 branch point. On merge, tagging v1.0.0-rc.3 triggers release.yml to cross-build aarch64/x86_64 and publish the GitHub Release.
