A release starts from a pushed tag. This page covers the release workflow, the published assets, the resolved-issue provenance in release notes, and the manual checks around tagging.

Pushing a tag matching v<semver> starts .github/workflows/release.yml. Owner approval to push the tag is separate from running local packaging. Pre-release tags containing - are marked prerelease.

Before any platform job starts, validation peels the tag ref to its commit, fetches full origin/main history, requires that commit to be its ancestor, and uses read-only actions access to find a completed successful CI push run whose head is exactly that commit. That exact run already includes the full source, unit, integration, platform-runtime, allocator, coverage, package, and Wiki-tooling gates. The release validator therefore checks only the workspace version and release-asset tooling before packaging; it does not rerun the platform test graph. A tag on an unreviewed branch, a tag whose main run failed or is missing, a version mismatch, or a release-asset contract failure cannot reach package construction.

All three packaging chains block publication. Each macOS architecture and the Windows release job run the exact built shipping binary's native smoke, in the default, frame-validation and device-recovery scenarios, before its artifact can advance; Windows does not rerun the GDI test because the release provenance boundary already requires the exact successful main CI result that proved EXERCISED. Windows Release restores the main-published vcpkg binary cache but performs its Rust target build without a Release cache write. All Release Rust target builds are cache-independent, so tag-specific cache entries cannot displace the bounded CI dependency caches. The Linux chain runs default, frame-validation and device-recovery package smokes on X11 and Wayland in separate steps with native process deadlines before its artifacts can reach publication.

The five required package assets are:

• SonicTerm-<tag>-mac-aarch64.dmg
• SonicTerm-<tag>-mac-x86_64.dmg
• SonicTerm-<tag>-windows-x86_64.msi
• SonicTerm-<tag>-linux-x86_64.deb
• SonicTerm-<tag>-linux-x86_64.tar.gz

Each package job emits a typed fragment containing tag, flat filename, platform, architecture, kind, and SHA-256. The publish job downloads only the registered package bundles, verifies each file and hash, requires the five platform/architecture/kind tuples, rejects duplicate tuples/names and unregistered release-like files, then generates:

• release-assets.json
• deterministic SHA256SUMS.txt, including the manifest hash
• release-upload-paths.txt, the exact list supplied to GitHub Release

Release notes retain manifest-derived downloads, integrity metadata, verification, and non-merge commit history since the preceding reachable tag (not the highest version tag). Missing predecessor lookup fails by default; fetch the complete tag history rather than silently treating a lookup failure as a first release. Only explicit RELEASE_FIRST=1 permits no-base notes and conflicts with any set PREVIOUS_TAG. Shallow repositories are rejected. In first-release mode the displayed history is limited to 200 commits; issue selection still considers the entire reachable history within its explicit bounds. The GitHub Release receives the five packages, release-assets.json, and SHA256SUMS.txt; fragment files and release-upload-paths.txt are internal workflow data.

scripts/release-issues.py supplies the Resolved issues section. It resolves head/base to commits, requires base ancestry, and includes every commit reachable from head but not base, including merge commits. Paginated REST commit-to-PR associations are discovery hints; a merged PR's GraphQL closingIssuesReferences and explicit commit closing keywords nominate issues. Refs #123, a milestone, and present-day closed state are not closure evidence. Issue-vs-PR identity is checked and issue entries are deduplicated, sorted, and Markdown-escaped; links are constructed only from validated owner/repository names and integer numbers.

An issue is included only when a GraphQL ClosedEvent.closer identifies an in-range commit, or a merged PR whose mergeCommit is in range. This supports merge, squash, and rebase integration without requiring REST timeline commit_id to be non-null. Mutable PR links alone cannot establish shipped closure; prior ancestor closures are not presented as newly delivered, and closures after head are excluded. Empty commit-to-PR association lists are normal. A genuine empty result says No linked issues resolved in this release range.

Canonical This reverts commit <full SHA> Git messages cancel the target's contribution; merge reverts also cancel introduced commits, and reverting a revert restores its contribution. A PR with a reverted associated constituent is omitted conservatively. Prose-only or partial/semantic reversals without canonical Git markers are not inferred. This is linked GitHub closure evidence, not a claim to find every fix or prove the runtime effect of arbitrary changes. Missing/deleted metadata, unknown non-null closer types, malformed schemas, inconsistent pagination, and ambiguous provenance fail generation instead of publishing a partial list.

A null closer never enters Resolved issues. Instead, nominated issues that are currently closed can appear under Manually closed issues (unverified release linkage) when their current closure event falls after the base commit date and no later than the head commit date (first releases have no lower date bound). The event and issue closure timestamps must agree within one second, accommodating GitHub's timestamp precision; missing/invalid dates or multiple matching events still fail. Previously shipped commit-linked closures remain excluded. This separate disclosure names the closure date and explicitly does not prove that the release resolved the issue; mutable PR links and dates never replace ancestry checks in the verified list.

The collector caches exact API pages, requests 100 entries per page, and permits at most 20 pages per connection, 2,000 range commits, 1,000 API attempts, 4 MiB per child output, and 32 MiB aggregate API output. Each request has 15 seconds inside a 900-second total deadline, long enough for 1,000 attempts at 0.75 seconds each, so a large range stops at the attempt cap rather than at the clock. Owned child trees are killed/reaped on timeout or output overflow. On Windows, a child whose exit and both output EOFs are observed and whose output decodes successfully returns without starting taskkill. Timeout, overflow, and decoding failure retain tree cleanup; POSIX cleanup is unchanged. Only timeout, HTTP 429, explicit rate limits, and HTTP 5xx retry (up to three attempts, bounded backoff). Authentication and schema failures do not retry. Exceeding a cap fails, never silently truncates. The publish job alone adds issues: read and pull-requests: read alongside its existing contents: write, and note generation receives the short-lived job token as GH_TOKEN; packaging permissions and exact-tag provenance remain unchanged.

For a read-only pre-tag preview, run from the checked-out repository with an existing authenticated gh session (CI uses its job token):

python3 scripts/release-issues.py --repo D0n9X1n/SonicTerm \
  --head <exact-reviewed-merge-sha> --base <previous-tag-or-commit>

Omit --base only for the first release. This helper does not create or require a new tag. bash scripts/test-release-notes.sh runs offline temporary Git-history and fake-gh tests as well as the manifest/download integration checks.

Before pushing a tag:

• verify the workspace version and intended tag;
• run the full gate and native release build;
• compare README and every affected wiki page with current config, logging, input, palette, rendering, window, platform, and package behavior;
• launch the package, exercise alternate-screen entry/exit, scrolling, busy panes, tab tear-out and child cleanup, and inspect adapter logs where relevant.

After pushing, verify every release job and the exact uploaded assets and checksums. A local package build is not publication.
