SCIO v0.2.0

Fixed

• Token budgets count billable-equivalent tokens (cache reads at 0.1x, writes at 1.25x) so prompt caching lowers the count it enforces (I-041).
• Prompt caching now covers the conversation: a third breakpoint on the last message block makes each worker turn re-read its transcript at cache price (I-040, docs/IDEAS_TRIAGE.md).
• A tool crash (e.g. view_file on a directory) is returned to the model as an error result instead of ending the run (I-032).
• Budget pre-check reserves half of max_tokens instead of all of it; explorer loops capped at 6 model calls / 8 tool calls; small task budgets raised to the tier the live router picks (I-033, I-035).
• tests_added wording: the tests that prove the features, existing or new; bug-fix tasks no longer loop on "add tests" (I-034).
• T1 verify adopts the worker's reported tests when the plan's guessed test names match nothing (I-037); worker turns capped at 12 model calls and transcripts trimmed from 30k characters (I-038); the planner no longer emits exploration steps and normalize_steps drops no-op steps and covers missing features (I-039).
• verify runs each reported test selector correctly: path::name node ids and file paths as positional pytest targets, bare words as -k; found by the first live Anthropic run (I-031).
• pdoc no longer warns on PEP 695 generics: scio/prompt/repair.py and scio/loop/agent_loop.py drop the __future__ annotations import (I-008).

Added

• evals/runner --parallel N: a task's trials run concurrently (independent sandboxes, checkpoints and budgets).
• Live Anthropic acceptance recorded: t001 pass^5 = 1.00 (5 trials) via an ant auth login profile.
• Live sandbox checks: tests/live/test_docker_live.py runs wherever Docker is available (CI runners included) and tests/live/test_e2b_live.py runs when E2B_API_KEY is set (I-016).
