Cutting v0.0.7 by hand missed the build.zig.zon bump; verify-dist caught it one CI round late. The cut becomes a compiled, tested tool (the same ruling that moved publication out of workflow shell into tools/release.zig), invoked from a thin justfile. Design reviewed and accepted by Codex (thread 01a020f9); its findings are folded in below.

justfile (repo root)

Recipes only — no variables, no embedded logic:

test → zig build test
itest → zig build test -Dintegration
admin-check → cd admin && npm run typecheck && npm run test && npm run lint && npm run format:check (the committed npm scripts, never npx: the repo records that npx can fetch an unpinned package)
goldens → the documented -Dcontract-samples-out invocation; comment says what admin/src/lib/contractSamples.gen.ts is: captured live API bodies the admin tests assert against
build → cd admin && npm run build, then zig build -Dadmin-dist=admin/dist (the default build embeds a placeholder page)
verify → itest + admin-check + zig fmt --check build.zig src tools — described honestly as the fast local checks, not the CI gate (it skips admin npm run build/assert-bundled, cross-targets, verify-dist)
release kind → zig build cut -- {{kind}} (kind ∈ major, minor, patch)

verify must NOT also depend on test: -Dintegration already runs the whole ordinary suite.

tools/cut.zig

Wired like the other host tools (hostTool + addRunArtifact, see build.zig ~230): zig build cut -- {major|minor|patch}. NOT installed to zig-out/bin. Its tests join zig build test.

Constants: one repo API base https://git.mial.net/api/v1/repos/mokhtar/nxdns (the tool can only ever target this repo — no configurability). The runs API needs a token (verified: anonymous GET is 401); read it from ~/.config/tea/config.yml (logins entry for git.mial.net); a missing token is a clear error naming the file.

Sequence

Derive the version: the argument is a bump kind — major, minor or patch — never a free-form number (a number validated as "greater semver" still admits every typo, and a published tag is immutable). Parse .version from build.zig.zon (precedent: tools/verify_dist.zig:220, container_check.zig:317). If v<zon-version> exists on origin, derive the next version from the bump kind (patch 0.0.7→0.0.8, minor→0.1.0, major→1.0.0; checked u32 arithmetic). If it is absent, the zon version is an in-progress cut: resume it instead of incrementing again, reported explicitly — this preserves the bump-committed-but-untagged rerun and local-tag adoption. The CHANGELOG check in preflight applies to the derived (or resumed) version, so a changelog written for the wrong bump kind fails as a mismatch.
Preflight: working tree clean; branch master; CHANGELOG.md has a ## [<v>] - YYYY-MM-DD heading (dated, the repo's observed form; do NOT require the date be today) with a non-empty section body (the CI tool refuses a blank section — failing later just burns the tag); the tag-free check follows the plan: a derived version does its own git ls-remote and refuses if v<v> exists; a resumed version reuses the absence that selected it (asking twice invites two answers). Transport/auth failure is always distinguished from "no match" (exit code + stderr, never "nonzero means absent") and refuses — on the resume path an error read as absent would resume a released version. The local tag namespace is checked too — see resumability.
Bump if needed: rewrite build.zig.zon atomically, reparse it, assert the git diff contains exactly that one file, then git commit -S -m "build: bump version to <v>". git runs with inherited stdio so pinentry can prompt; check the child's actual termination state.
Push master, capture the exact HEAD sha; all later status lookups and the tag use that sha explicitly.
Wait for CI: poll the runs API for the ci.yml run matching that sha and event push. A run-id floor captured before the push scopes the match — applied only when the push actually moved the ref (git push --porcelain destination flag), so a no-op push (resume case, or a concurrent identical push) adopts the existing run for that sha. Require the run to appear within a startup deadline; wait for its terminal conclusion. Refuse to tag on anything but success, naming the failing job from the commit-status contexts. Every HTTP attempt individually bounded by a monotonic deadline; transport/JSON errors are reported, never silently treated as pending.
Reassert HEAD and tree unchanged, then git tag -s v<v> -m v<v> <sha> and push the tag.
Wait for the release run (matched by workflow path release.yml@refs/tags/v<v> — Gitea reports tag pushes as event "push"): startup deadline for the run to appear; the completion clock starts at first sighting, with a ceiling derived from the workflow's sequential jobs — guard 15 + gates 60 (the tool's own CI bound) + publish 120 (release.yml:220) = 195 minutes. Before tagging, reassert HEAD, the tree, and (for an adopted tag) the tag object id; every tag pushed — created or adopted — must carry a signature whose VALIDSIG primary fingerprint equals the one release.yml pins as TAG_SIGNING_FPR. Report the terminal conclusion; on failure name the failing context.
On success: GET the release object, require it published (not draft), print the tag and asset names.

Resumability

A failed run must not strand the operator:

Bump pushed, then failure: rerun continues (preflight sees the version already bumped).
Local tag exists but never reached origin: verify it is an annotated tag by this tool's convention pointing at the current HEAD — adopt it; otherwise refuse with the exact git tag -d to run. Never delete a tag that exists on origin.

Tests (in-file, join `zig build test`)

Pure functions unit-tested: semver validation (accept/reject table incl. leading zeroes, v prefix), bump-kind parse, derivation table with the minor/major resets and overflow refusals, derive-vs-resume decision for all three kinds, zon .version parse + rewrite round-trip, changelog heading + non-empty body check, runs-JSON → decision (running / success / failure / no-run), tea-config token extraction. Process spawning and HTTP live behind thin call sites and are not mocked.

Anti-requirements

No general release framework; no shared process plumbing extracted unless a third caller appears (container_check.zig:24 rule).
No confirmation prompts — invoking just release <kind> is the authorization.
No secrets in argv, no token printed.

Acceptance

just --list shows the recipes; just verify passes locally.
zig build cut -- patch derives the next version and refuses in preflight on a dirty tree or a missing changelog section, mutating nothing; zig build cut -- 0.0.9 and -- banana refuse naming the three kinds.
zig build test and -Dintegration 0 failed; zig fmt --check clean.
