v0.2.0

[0.2.0] - 2026-02-26

Added

• Almock (LLM Mock) — Model.Almock() for development and testing without an API key. Configurable pricing tiers (LOW, MEDIUM, HIGH, ULTRA_HIGH), latency (default 1–3s or custom), and response (Lorem Ipsum or custom text). Examples and docs use Almock by default; swap to a real model with one line.
• Memory decay and consolidation — Decay strategies with configurable min importance and optional reinforcement on access. Memory.consolidate() for content deduplication with optional budget. Entries without IDs receive auto-generated IDs.
• Checkpoint triggers — Auto-save on STEP, TOOL, ERROR, or BUDGET in addition to MANUAL. Loop strategy comparison (REACT, SINGLE_SHOT, PLAN_EXECUTE, CODE_ACTION) documented in advanced topics.
• Provider resolution — ProviderNotFoundError when using an unknown provider, with a message listing known providers. Strict resolution available via get_provider(name, strict=True).
• Observability — Agent runs emit a root span plus child spans for each LLM call and tool execution. Session ID propagates to all spans. Optional OTLP exporter (syrin.observability.otlp) for OpenTelemetry.
• Documentation — Architecture guide, code quality guidelines, CONTRIBUTING.md. Community links (Discord, X) and corrected doc links.

Changed

• Model resolution — Agent construction with an invalid provider in ModelConfig now raises ProviderNotFoundError instead of falling back (breaking for callers relying on LiteLLM fallback).
• API — syrin.run() return type and tools parameter typing clarified. Duplicate symbols removed from public API exports.
• Docs — README and guides use lowercase syrin imports. Guardrails and rate-limit docs: fixed imports and references.

Fixed

• Response and recall contract; spawn return type and budget inheritance. Rate limit thresholds fully controlled by user action callback. Guardrail input block skips LLM; output block returns GUARDRAIL response. Checkpoint trigger behavior (STEP, MANUAL). Session span count when exporting. Edge cases: empty tools, no budget, unknown provider.
