Milestone: v1.0 GA — tied to TG v2 GA, channels live

[tig]

Tracks the final milestone in specs/clet-spec.md §7.

Exit criteria

Release

• Tied to Terminal.Gui v2 GA (version 1:1 per §5.6).
• Triggered by the repository_dispatch from the TG v2 GA release tag.
• §5.3 smoke gate green across all six RIDs (osx-arm64, osx-x64, linux-x64, linux-arm64, win-x64, win-arm64).

Channels live

• Homebrew: brew install gui-cs/tap/clet works on macOS arm64, macOS x64, Linux x64. Signed and notarized macOS bottles.
• WinGet: winget install gui-cs.clet works on Windows 10/11 x64 and arm64. Authenticode-signed.
• NuGet: dotnet tool install -g clet works on any platform with the .NET SDK.

Documentation

• User docs at docs/installing.md, docs/json-schema.md, docs/exit-codes.md published.
• Rollback runbook at docs/runbooks/release-rollback.md finalized — open questions resolved (tag scheme, on-call, paging channel, retention).
• Threat model (full document, not just Appendix A sketch) published.
• clet --help and clet help <alias> reflect final v1.0 surface.

Repo hygiene

• Issue templates for clet bugs in place (bug report, feature request, release-incident).
• CONTRIBUTING.md covers the View-author path: implement IClet<T> or IViewerClet, register the alias, ship.
• CODEOWNERS reflects current maintainer set.

Success-tracking baselines (per press release "what does success look like 12 months after launch")

The following start counting at v1.0 GA, not as exit criteria; capture the t=0 baseline now so 12-month review has data.

• Opt-in usage ping infrastructure decided (deferred per §9 OQ Add clet implementation specification and release runbook #1 — confirm v1.1 path).
• Homebrew install counter accessible.
• WinGet install counter accessible.
• AI-agent integration outreach started (target: 3+ products integrating clet list --json within 12 months).

Dependencies

• Terminal.Gui v2 GA shipping.
• All §6 test layers green in CI continuously since v0.9.
• Rollback runbook exercised at v0.9.

Out of scope

• Third-party clet runtime loading (Assembly.LoadFrom) — v2.
• Clet.Abstractions published NuGet — v2, gated on plugin loading.
• password clet — its own threat-modeled release.
• Additional viewer clets (json, log, diff) — v1.x or v2.
