release 0.42.1 on GitHub →

Two patches addressing items deferred from the v0.42.0 release notes:

Fixed

• scripts/version-sync.mjs idempotent TOML rewrite. The script's TOML rewrite used updated === content to detect "no match", but that check returns a false negative when the file is already at the target version (e.g., running npm version 0.42.1 when herdr-plugin.toml already reads version = "0.42.0"). String.prototype.replace returns the original string both when no match exists AND when the replacement was a no-op — so we'd mistake idempotency for a missing line. Fix: use a regex + .test() to distinguish "no match found" from "replacement was a no-op". Idempotent runs now succeed quietly. Symptom: v0.42.0 release shipped with a "Failed to sync herdr-plugin.toml" log line. Manifest was always correct — this was just a noisy false negative.

Added

• tests/integration/cli-dispatch-syntax.test.ts (10 cases): validates the per-CLI PARALLEL dispatch table from subagents.md. Two layers:
• Binary availability check for pi (built-in + pi-subagents extension), opencode, codex, claude-code (optional).
• Static call-shape validation for each documented PARALLEL invocation shape (tasks[] + concurrency for pi-subagents, multi-Task-per-turn for claude-code, parallel codex-exec subagents, opencode PR #14196 shape, generic &/wait). Includes a resolveCli() helper that actively skips node_modules/.bin directories when searching PATH — prevents a known shadowing issue where vitest's modified PATH included a local older pi-coding-agent@0.73.1 dev dep that shadowed the global runtime. Real LLM session-launching smoke tests are explicitly out of scope (require a live model session; documented as different test class).

Note on the npm package name. @calionauta/stelow is the canonical name (set in package.json). The package was never published to npmjs.com at any name (confirmed via npm view @calionauta/stelow and npm view @renatocaliari/stelow both returning 404 at release time). Installers in this repo use the git URL (git:github.com/calionauta/stelow); the name field is a future-facing label for any eventual publish. External references that were intentionally preserved (NOT bug, NOT regression): - docs/design/stelow-board-herdr.md: a future separate project. - skills/cali-product-discovery/SKILL.md (lines 95, 101, 107): credits to a third-party author's repositories (not stelow). - setup.sh line 70 (pi-tool-repair-layer): a separate upstream package with its own naming. - docs/archive/: 2026-05-20 archive snapshot.
