Know what was tested, and what was not.

This matrix describes Day Shift 0.2.3. A published archive, portable prompt, or internal dogfood record is not a universal platform or coding-assistant compatibility promise.

Read operational limits Inspect proof records

runtime

Linux x64, Node.js 20, POSIX shell

supported with constraints

Evidence date: 2026-08-10
Tested versions: Day Shift 0.2.3; Node.js 20
Boundary: Repository execution evidence covers this runner shape; it is not a promise for every Linux distribution, shell policy, repository layout, or newer Node.js version.
Repository sources: tests_v2/cli/release/output-lifecycle.suite.js; apps/website/public/downloads/0.2.3/release-manifest.json

distribution

macOS x64 and arm64 system-node archives

supported with constraints

Evidence date: 2026-08-10
Tested versions: Day Shift 0.2.3 publication layout
Boundary: The release manifest and archive layout are verified. Native CLI execution on macOS was not exercised by this repository task.
Repository sources: apps/website/public/downloads/0.2.3/release-manifest.json; tests_v2/cli/release/output-lifecycle.suite.js

distribution

Windows x64 and arm64 system-node archives and PowerShell installer layout

supported with constraints

Evidence date: 2026-08-10
Tested versions: Day Shift 0.2.3 publication layout
Boundary: Archive and installer layout are verified on the repository runner. Native execution requires a Windows command shell and was not exercised here.
Repository sources: apps/website/public/downloads/0.2.3/release-manifest.json; tests_v2/cli/release/output-lifecycle.suite.js

shell

Bash, Zsh, and Fish completion generation

supported with constraints

Evidence date: 2026-08-10
Tested versions: Day Shift 0.2.3
Boundary: Generation is tested. User shell configuration, plugin managers, and interactive startup behavior remain environment-owned.
Repository sources: tests_v2/cli/completion/completion.test.js

coding assistant

Codex used through repository-local instructions and CLI commands

experimental

Evidence date: 2026-08-10
Tested versions: Day Shift 0.2.3 repository workflow
Boundary: This repository contains internal dogfooding evidence, not a direct product integration, independent certification, endorsement, or proof of arbitrary agent compliance.
Repository sources: .day-shift/planning/governed/28-website-and-documentation-experience-revamp/phases/06-governed-promotion-and-recovery-experience/milestones/03-publish-promotion-guidance-and-demo-evidence/reconciliation.md

coding assistant

Claude Code and other prompt-capable coding assistants

untested

Evidence date: 2026-08-04
Tested versions: None
Boundary: Portable Markdown guidance does not prove model compatibility, reliable behavior, or integration support.
Repository sources: .day-shift/specs/28-website-and-documentation-experience-revamp/website-and-documentation-experience-revamp.md

integration

Direct coding-assistant control or behavioral enforcement

unsupported

Evidence date: 2026-08-04
Tested versions: None
Boundary: Day Shift exposes repository contracts and commands. The external integration and accountable human determine whether an agent reads or follows them.
Repository sources: apps/docs/src/content/docs/agents/review-boundaries.md

Status contract

Every row carries one bounded status.

Supported means evidence exists only for the named scope. Constrained, experimental, untested, unsupported, and planned items must not be promoted into broader claims.

supported

The named behavior is covered by repository evidence for the stated scope.

supported with constraints

The named behavior is covered only inside the stated version, platform, or operating boundary.

experimental

Repository evidence exists, but the behavior is not a stable compatibility promise.

untested

No repository evidence supports this combination; publication or prompt portability does not change that status.

unsupported

The current product does not provide this behavior.

planned unavailable

The behavior may be discussed as future work but is not currently callable.
