v0.0.1

First release.

Task authoring

• Typed do.ts via defineTasks() / task() — compile-time dependency
  checking with did-you-mean, typed env (Standard Schema: zod / valibot /
  arktype) validated before anything runs, typed per-task CLI args with
  auto-generated --help and shell completions.
• Conditional deps ({ task, if: "CI" | (env) => boolean }) and optional deps
  (optional("name")).
• Task data outputs: run()'s return value flows to dependents via
  ctx.deps, typed end-to-end with from(), replayed from cache on hits.

Execution

• Parallel DAG scheduler with fail-fast, --continue, multiplexed output,
  and an in-process fast path for pure dependency chains.
• Services (persistent: true) with readiness probes
  (ready: { log | url | port }) gating dependents.
• Opt-in retry policies and per-attempt timeoutMs.
• Watch mode with affected-subgraph re-runs and service restarts.

Caching

• Fingerprint cache (content-hashed inputs with an mtime+size fast path,
  task definition, env output, args, dep fingerprints, dep data outputs).
• outdo explain <task> — per-component cache diagnosis without running.

Monorepos

• Bun workspace awareness (pkg#task, bare-name fan-out, --filter
  microsyntax) and git-aware --affected[=rev] selection.

Hardening (pre-release review)

• A full-code review pass fixed 25+ confirmed defects before first publish,
  including: an IPC race that could report a green task as failed; unenforceable
  in-process timeouts (timeout plans now always use the child backend); cache
  I/O failures crashing the scheduler (now degrade to uncached success); empty
  ctx.args in multi-task runs; --affected silently doing nothing on failing
  git commands, non-ASCII paths, and subdirectory repos; garbled zsh
  completions; a constructible cache-fingerprint collision; watch-mode error
  handling (watcher errors now fall back to polling, Ctrl-C aborts in-flight
  re-runs); UTF-8-safe multiplexed output with per-fd grouped flushing; and
  --output-logs=errors-only now working in stream order.

Observability & automation

• --json run report (per-task status, timing, cache result, critical path),
  --profile Chrome trace export, ls --json, graph --json, --dry=json,
  --print-env --json, stable exit codes, machine-readable errors,
  llms.txt on the docs site.
