Release

Release — the DOS kernel

Semver: major.minor.patch. Patch = bug fix, minor = new feature, major = breaking.

DOS is a substrate, not an app. This skill is the DOS-context adaptation of the job release skill. It is deliberately thinner: DOS single-sources its version from pyproject.toml (one marker, not four), ships no release-asset zip archive, screenshots, versioned-install snapshot, plan-state regeneration, apply-loop gate, or fanout/dispatch manifest. The dist artifacts — one wheel per OS/arch, each embedding its native dos-hook fast-path binary at dos/_bin/ (docs/286), plus a pure-source sdist — are built by CI (publish.yml via scripts/build_wheels.py), never by this skill locally. The verification step is the kernel test suite + the truth syscall, not an apply pipeline. If you find yourself reaching for any of those job-only ceremonies, you're in the wrong repo's skill.

One exception — the plugin's native hook binaries. The Claude Code plugin (claude-plugin/) bundles the compiled dos-hook fast-path binaries (docs/125 GHF4), committed into claude-plugin/bin/ so a marketplace install (a git clone) is a direct install. They are NOT a release asset and NOT in the wheel — they live in the git tree. Step 5.5 rebuilds them so a release never ships a stale binary against changed Go source.

Trunk is master (there is no main branch in DOS). Every git push in this skill targets master. Master-direct is the deliberate branching model for now (a trunk+lane-branch PR cutover is planned, evidence-triggered — not a dev branch); this skill assumes it.

This repo is PUBLIC and the tag is a publish trigger (the 2026-06-10 cutover). Three consequences every release run must respect:

1. A push IS publication. origin is the public anthony-chaudhary/dos-kernel. The machine-local pre-push hook (.git/hooks/pre-push) runs the leak scanner (scripts/leak_scan.py, a gitignored sync of the canonical ../dos-private/tools/leak_scan.py) and is fail-closed: a hit — or a missing scanner — refuses the push. On a refusal: scrub and amend, never --no-verify ("a leak is a refusal, not a warning"). Details in the runbook's Public-repo push gates section.
2. Pushing the vX.Y.Z tag starts the PyPI publish pipeline. publish.yml fires on every v* tag: it builds the per-platform wheels + sdist, asserts tag == pyproject.toml version, refuses to upload any SHA without a green ci.yml run on it (the ci-green witness gate — it polls while CI finishes), then pauses at the protected pypi environment for the operator's approval before the OIDC Trusted-Publishing upload. So Step 6's tag push is also the publish request, and Step 7.4 is "surface/approve the pipeline," not "run twine."
3. Release notes are public documents. docs/releases/vX.Y.Z.md ships to the world (and into the GH release body). No dev-machine absolute paths, hostnames, or personal identifiers; private-SUBJECT prose (operator process, fleet audits, launch mechanics) is born in dos-private, never here — the CLAUDE.md route-privacy-at-authoring-time rule, applied to the notes you draft in Step 3.

Cadence — two channels, one rule

• Rolling vX.Y.Z (this skill): ship whenever the gates are green. A coherent, user-visible unit of work + a green suite is enough to cut a tag — several per week is healthy, not churn. The cost is low by design: every hard gate is mechanical and already wired (pre-push leak scan, ci.yml on the push, the publish ci-green witness, one human approval click for PyPI). Don't batch work waiting for a "big enough" release — the oracle reads git, and unshipped work is NOT_SHIPPED.
• Stable stable/<codename> (/stable-release): promote deliberately. The infrequent counterweight — a promotion of an already-soaked rolling tag (green suite + green third-party CI + clean truth syscall + soak window), producing the evidence file + the tag consumers pin in production (pip install dos-kernel==<underlying>). Rolling moves fast because stable exists; stable can afford its soak window because rolling carries the urgency.
• Semver carries the compatibility promise; the channel carries the trust promise. Major = breaking ABI (verdict vocabulary, syscall signature, SubstrateConfig shape). A major bump deserves a stable promotion soon after it soaks, so consumers get a provably-good anchor on the new ABI.

Git authorization. Invoking this skill is the user's explicit authorization to run git add, git commit, git tag, and git push origin master/vX.Y.Z as specified in Steps 5–6. The "never commit/push unless asked" default does NOT apply here — committing and pushing IS the skill's job, and stopping mid-flow to re-confirm each git mutation is the wrong behavior. Confirmation is still required for anything destructive the steps don't list (force-push, history rewrites, branch deletion, git reset --hard).

The kernel-vs-tooling boundary. The release scripts (scripts/release_*.py) and this skill are dev/release tooling that operates ON the package — they are never imported BY dos.*. Editing them never touches the kernel's import graph, so the "kernel imports no host, no scripts/" litmus in CLAUDE.md stays intact. Keep release logic here, not in src/dos/.

Fast path (most releases): Steps 1–7.5 below. Edge cases (racing agents, version drift, release-notes nuance) live in release-runbook.md — load it only when a step tells you to.

This skill is the deliberate act; the always-on nudge is the reminder. A second, advisory Stop hook (scripts/git_hygiene.py, wired in .claude/settings.json) runs at every stopping point and prints a one-line "N uncommitted files on master, K commits not pushed — commit the lane or run /release" whenever the tree is dirty or the branch is ahead of its upstream. That nudge is advisory-only — it never blocks, commits, or pushes (the docs/274 rule: a blocking Stop hook force-loops interactive sessions). Its whole job is to keep "ship the finished work" the default reflex; this /release skill is what the nudge points you to when the dirty work is a coherent, release-worthy unit. The two compose: the hook makes the obligation visible at every turn-end, the skill discharges it. The hook's lease-aware fold (it subtracts paths a live /dispatch-loop legitimately owns) is the same dos.lane_journal fold Step 1.6 below uses, so the nudge never nags about a path this skill would itself defer.

Hot-tree safety (the DOS-native bits). This repo's working tree is routinely written by several concurrent agents at once (the project-dos-multi-session-hot-tree discipline). Two steps below exist for that: Step 1.6 auto-defers any dirty path a live lane lease still owns — read from DOS's own lane journal, the same fold dos top renders — so the release never ships a loop's mid-flight edit. And the staging rules in Steps 1.5 + 5 are index-race-safe by construction (commit by explicit pathspec; never a bare git add -A), because a bare add/commit on this tree grabs another session's staged or unstaged content (five separate memories record that scar). Both are dogfood: the release flow is itself one of the agents the kernel referees, so it reads the kernel's evidence before it writes the most contended region (a tag on master).

Step 0: Scope (default — derive and suggest a scope unless --whole-tree)

A scoped release is the default. DOS's working tree routinely carries in-flight WIP — the plan series (docs/NN_*-plan.md), a concurrent loop's mid-theme edits — that is not necessarily part of this release's theme. (Strategy/business prose no longer lives in this tree at all — it routes to dos-private at authoring time; if you see it dirty here, that's a misroute to flag, not to ship.) A whole-tree release sweeps all of it into one chore blob. So on a bare /release, derive a recommended scope and proceed scoped — don't default to whole-tree.

Bare /release (no --scope, no --whole-tree): derive-then-proceed

1. From the Step 1 payload, derive a recommended scope: the dominant work theme(s) of the dirty tree + commits_since_tag[].subject. Usually 1–2 tokens (e.g. stamp-convention, arbiter, decisions, oracle).
2. State the suggestion before cutting, one line: Suggesting scoped release: --scope arbiter (overrides: --whole-tree, or --scope <other>).
3. Proceed with that scoped snapshot — do not block waiting for confirmation. The operator can redirect in their next turn; absent a redirect, the scoped release is correct and forward motion wins.
4. If the dirty tree is genuinely one coherent theme, the derived scope covers the whole tree anyway — say Suggested scope covers the full dirty tree and proceed.

--whole-tree is the explicit opt-out: every dirty path (modulo the auto-deferred scratch/release-draft buckets) is in-scope, no scope derivation.

--scope <theme-token> (explicit, repeatable) pins the scope: the release is limited to paths belonging to one or more named themes; every dirty path that does not match is left uncommitted.

A --scope token (derived or explicit) is matched case-insensitively as a substring against both a path and the subject of each commits_since_tag entry. A path is in-scope if it matches any token directly, or sits under a directory a matching commit touched.

Scoped-release rules (apply to a derived scope and an explicit --scope):

• The Step 2 snapshot is (modified + untracked.tracked_docs + untracked.other) intersected with the scope match, minus the auto-deferred buckets.
• Step 1.5 clusters only in-scope paths into thematic commits. Out-of-scope dirty paths are neither staged nor committed — list every one in the final summary under Out-of-scope (left dirty): ….
• If the scope match is empty — stop and report: nothing in this theme to release. Do not fall back to a whole-tree release.
• Bump level, release-notes, version bump, tag, push, and the GH-release ceremony are unchanged — a scoped release still cuts a real version tag.

Step 1: Pre-digest context

Run scripts/release_context.py. One JSON payload covers git state + version drift + per-file diff previews + the prior-release style cue. Read it once; do NOT re-run git log, git status, git diff, or read .gitignore / individual docs/releases/v*.md / untracked source files.

python scripts/release_context.py --limit-commits 50

Read the JSON inline from the Bash tool result — do NOT redirect to a file.

Hard cap on git log polling. The single release_context.py read is the only sanctioned git log for this skill. Never run git log <same-pathspec> more than 3 times in one session. Wait on the spawning Bash <task-notification> rather than polling a ref on a wall-clock cadence.

JSON keys → consumer step:

Load release-runbook.md only if:

• drafted_release_past_tag is non-null → another agent is mid-release.
• version_files.drift is true → pyproject.toml and the __init__.py fallback literal disagree.

Untracked artifacts are auto-in-scope by default (subject to Step 0 scope). untracked.tracked_docs (anything under docs/), untracked.other (new modules, tests, configs, .claude/ skill/memory edits), and modified all get staged with the snapshot. Only scratch and release_drafts are auto-deferred.

Scoped release (the default): the auto-in-scope default is replaced by the Step 0 scope match. Whole-tree auto-in-scope applies only when --whole-tree was passed.

Step 1.5: Pre-release WIP snapshot (only if working tree is dirty)

Skip if clean_tree: true. Otherwise commit the in-flight WIP before drafting the release, so each thematic change lands as its own git log entry and the release commit carries only version-marker churn + the release-notes file.

Invoking /release is your authorization to make these WIP commits too — same scope as Steps 5–6. Don't stop to re-confirm each thematic commit.

Inputs

Re-read the release-context JSON. All of modified, untracked.other, and untracked.tracked_docs are in-scope (subject to Step 0 scope) and get committed. untracked.scratch → rm -f. untracked.release_drafts → leave alone (Step 3 owns the new notes file).

Concurrent-agent + phantom-diff guard (read first)

For every path in modified, inspect its modified_diff_previews[path] value (already in Step 1 — do NOT shell out to git diff per file). Missing key → the diff was empty or line-ending-only; leave it unstaged. Value with ONLY - lines for content already in HEAD → a concurrent agent committed underneath you; do not stage it, note in the summary.

Check phantom_diffs. DOS's state plane is git-native YAML (dos.toml, execution-state.yaml). Any path listed in phantom_diffs parses identically to HEAD but shows a large textual diff — a writer round-tripped + reformatted it. Do NOT stage a phantom-diff path; restore it from HEAD (or fix the writer) and note it in the summary.

Group into thematic commits

Consult untracked_doc_previews and commits_since_tag[].subject to cluster dirty paths into 2–5 commits that each map to one work theme. Conventions:

• Match the prefix style of recent commits (DOS uses conventional-commit-flavoured subjects — feat(efficiency): …, docs(CLAUDE): …, fix(loop_decide): … — plus plain area: like paper: / release: and docs/NN …: plan refs). The commits_since_tag list is the cheat-sheet.
• Stage by explicit pathspec, one git add <path>… per commit — never git add -A/./-u. On this concurrently-written tree a blanket add sweeps in another session's in-flight edits (the feedback-commit-pathspec-on-shared-tree scar). Stage exactly the files of this theme.
• Commit by pathspec too: git commit -m "<subject>" -- <path>… (the -m BEFORE the --). A bare git commit with no pathspec commits whatever is staged — including a concurrent session's staged content — under your message (feedback-shared-index-bare-commit-grabs-concurrent-staged). Naming the paths scopes the commit to your lane.
• Caveat — a pathspec commit reads the WORKING TREE, not the index for the named paths. So git commit -- <path> on a file that a sibling session is also editing unstaged will still sweep their hunks (feedback-pathspec-commit-pulls-working-tree). For such a hot, interleaved file: stage your hunks as a patch, reset, re-apply (git diff -- <f> > /tmp/p; git checkout HEAD -- <f>; git apply /tmp/p) or simply hold the file out of this release and note it — do not hand-split with git add -p (no tty here). The Step 1.6 lease auto-defer removes the common case (whole files under a leased dir) before you reach this.
• No Co-Authored-By line.
• If a pre-commit hook runs the suite, let it run; fix on failure, never --no-verify.
• Windows note: when a subject carries backticks / pipes / §, pass it via a message file (git commit -F msg.txt -- <path>), and write that file UTF-8 without a BOM — Out-File utf8 / Set-Content utf8 emit a BOM that lands in the commit subject (feedback-pathspec-commit-pulls-working-tree). The --lint-prefix check below flags a leaked BOM.

Best-effort, don't stop

Bias is forward motion. Same path across two themes → group with the theme that owns more of its change-set; mention the split. Unclassifiable file → fold into the closest thematic commit (or a chore: <area> catch-all). More than 5 themes → fold the smallest two together.

After this step the tree is clean except (optionally) any path you noted as stale-vs-HEAD or phantom.

Optional: --lint-prefix (opt-in commit-subject sanity check)

If the operator passed --lint-prefix, run scripts/check_commit_prefix.py against each thematic-commit subject you just wrote (and, if you like, the Step 5 release-commit subject). The lint is warn-only — it never blocks; exit is always 0:

python scripts/check_commit_prefix.py --subject "<your subject>"

On a known prefix the lint is silent; on an unknown one it prints lint: unknown prefix '<x>' to stderr; on a leaked UTF-8 BOM it prints a BOM warning. Surface any warning in the final summary as an observation — do not rename the commit, do not amend, do not stop. The asymmetric goal is to catch a new commit that accidentally lands with a malformed / prefix-less subject; the warning is the signal, the operator is the gate. Skip this step entirely when --lint-prefix was not passed (the prefix shapes already cluster cleanly enough that strict enforcement would be ceremony). This is the cheap syntactic witness; the semantic one (dos commit-audit, "does the subject's claim match its diff?") runs post-commit in Step 7.6.

Step 1.6: Auto-defer paths a live /dispatch-loop owns (DOS-native)

/release is safe to run while one or more /dispatch-loops are active — it does not wait and does not refuse. It auto-scopes itself away from the paths those loops are still writing, so a bare /release is always a non-event on a hot tree.

This is the DOS-native form of the auto-defer: the active_leases key in the Step 1 payload is DOS's own kernel WAL (dos.lane_journal) folded to the live-lease set — the exact same fold dos top renders to show which lanes are held right now. So the release flow reads the same evidence dos arbitrate admits against, and defers a leased region the way the arbiter would refuse a contended lane. (Skip this step if active_leases is empty — no live loop, whole-tree as normal.)

Each entry is one live lane lease: {lane, lane_kind, tree, stale, holder, age_s, heartbeat_age_s, ttl_s}. The tree field is the lease's glob-region list.

• For every entry with stale: false, move each dirty path in the Step 2 snapshot that matches one of that lease's tree globs into an auto-deferred (active lease: <lane>) bucket — excluded from the snapshot. Glob match is the same shape dos arbitrate uses: an exact path, a dir/ prefix, or a dir/* / *_suffix.py wildcard.
• A stale: true lease is reported but not deferred — its heartbeat is past the TTL, so the loop died without releasing and its region is fair game (the same stale-steal rule the kernel's lease arbiter applies).
• The version-marker files (pyproject.toml, src/dos/__init__.py, the plugin manifests) are never inside a lane tree, so the version bump + tag + push always proceed — the release still cuts a real version tag, it just carries a narrower commit set. This is the same outcome as a --scope release (Step 0): reuse that path, no new tag/version logic.
• List every lease-deferred path in the final summary under Lease-deferred (left dirty): … with the owning lane, so the operator knows those changes ship in the next release once the loop drains.

The scope match (derived by default in Step 0, or explicit via --scope) and the lease auto-defer compose: a path must be in-scope and not owned by a live lease to be committed. A leased path's changes are mid-flight, not done — shipping them now would be the bug.

Step 1.7: Pipeline backlog sweep (keep the channels on track)

A release is the natural checkpoint for the two slow-moving obligations the pipeline leaves behind — an unapproved publish and a stale stable channel. Two cheap reads now, two lines in the final summary:

gh run list --workflow publish.yml --limit 5 --json displayTitle,status,conclusion
git tag -l 'stable/*' --sort=-creatordate | head -3

• Outstanding publish approval(s). A prior tag's publish run sitting at status: waiting is a release that never reached PyPI — the approval click was forgotten (v0.23.3 sat unapproved on its first day). Surface it by name: vX.Y.Z publish still awaiting approval — PyPI is N versions behind. A failure conclusion on a prior tag means that tag is dead (its changes ride THIS release); note it so nobody wonders why PyPI skipped a number.
• Stable-channel lag. Compare the newest stable/* tag's underlying version to the version this release will cut. When the gap has grown to a meaningful run (several minors / a few weeks), add the one-line nudge: stable lags by N releases — consider /stable-release once the latest tag soaks. This skill only nudges; /stable-release owns the decision and its soak gate.

Both reads are advisory — they never block the release. Their whole job is that no obligation survives un-surfaced past the next release.

Step 2: Decide bump level + snapshot files

From the JSON:

• Preflight (docs/295 P1) — read these two keys FIRST. If workflows_parse_ok.ok is false, a workflow file is unparseable: CI fails in 0 seconds on every push, so this release can never satisfy the publish ci-green witness — fix the named file (it's in workflows_parse_ok.files) as a thematic commit before proceeding. If ci_on_head.status is red, the trunk this release builds on is already failing — diagnose ci_on_head.latest_trunk_ci, fix forward first (or confirm the failure is a concurrent agent's in-flight breakage that your snapshot does not touch, and say so in the summary). unknown/none is advisory only — note it and proceed (fail-to-abstain: an offline gh never blocks a release).
• Bump level: patch unless a commit subject (or the user's summary) indicates a new feature (minor) or breaking change (major). New kernel syscall / new driver / new CLI surface = minor. Bug fix / docs = patch. Breaking ABI change (verdict vocabulary, SubstrateConfig shape, syscall signature) = major. Just pick — don't ask.
• docs_only advisory: if docs_only.docs_only is true, this is a legitimate release in DOS (the plan series and HACKING.md are first-class substrate deliverables — unlike job, DOS does not refuse a docs-only release). Pick patch and a docs theme, and proceed.
• Snapshot: modified + untracked.tracked_docs + untracked.other, minus scratch/release_drafts, intersected with the Step 0 scope (full set only on --whole-tree), minus any path Step 1.6 deferred under a live lease. Write the list down; it's frozen from here.
• Clean tree (clean_tree: true, no commits-since): nothing to release — stop.
• Clean tree with commits-since-tag: snapshot is empty; only version files + release notes get staged.

Delete any untracked.scratch entries with rm -f before proceeding. Never stage *.zip, *.exe, *.html research scrapes, _scratch/, or .dos-workspace/.

Step 3: Draft the release file

Compute the new version, then write docs/releases/vX.Y.Z.md. (Create the docs/releases/ directory on the first-ever release — DOS has none yet.) Mirror the shape in prior_release_style when present; otherwise use the minimum-viable shape below. Source per-bullet content from commits_since_tag[].files, modified_diff_previews, and untracked_doc_previews — all already in the Step 1 payload, no extra Reads.

---
version: X.Y.Z
date: YYYY-MM-DD
headline: "One short sentence, ≤120 chars, operator-facing outcome."
themes: ["arbiter"]
highlights:
  - "3–6 items, each ≤15 words, no semicolons. Lead with the user-visible change."
---

**TL;DR** — 1–2 sentences on what shipped and who should care.

## Section heading (one per major theme)

- **What changed** — one short sentence, no semicolons.
  - *Why:* one line if motivation isn't obvious.
  - *How:* `src/dos/file.py:func` or mechanism.

DOS theme slugs (reuse when possible, matching the syscall ABI + layering in CLAUDE.md): oracle (verify), wedge-reason / refusal (refuse), arbiter (lease/arbitrate), run-id / lane-journal (correlation spine), config / seam (SubstrateConfig), cli, drivers, reasons, decisions, docs.

Full rules + anti-patterns in release-runbook.md. Load only when the change spans 3+ themes.

Step 4: Bump the version markers

One command updates all five markers in lockstep — pyproject.toml (source of truth), the src/dos/__init__.py fallback literal, the Claude Code plugin manifest (claude-plugin/.claude-plugin/plugin.json), the marketplace plugin entry (.claude-plugin/marketplace.json), and the FTUE doc banners + skill-pack samples (README.md, docs/QUICKSTART.md, docs/HACKING.md, examples/playbooks/01_onboard-a-repo.md, and the dos_version/DOS v… literals in src/dos/skills/*):

python scripts/release_bump.py X.Y.Z
python scripts/build_plugin.py        # resync the bundled skill copies the sweep touched

The bumper prints a JSON report. If any target reports "ok": false, read the reason and fix by hand. If drift_after_bump is true, the lockstep markers disagree — reconcile all to the same value before committing (this is the exact failure the __init__.py comment + tests/test_plugin_manifest.py record: a source-checkout CLI misreporting its version, or the plugin bundle fronting a stale one — the plugin drifted to 0.13.0 behind a 0.15.0 package exactly because the bumper once didn't know about these files). The docs target is keyed on the old→new pair (it rewrites only literals naming the old version) and is NOT part of the drift guard; it drifted on v0.19.0 (the FTUE docs stayed at 0.18.0, hidden by stale install metadata — 2026-06-10 audit) which is why the sweep now exists. The build_plugin.py re-run after the bump resyncs the generated claude-plugin/skills/ mirror of the swept src/dos/skills/ samples, so the byte-level test_plugin_manifest skill-sync test stays green. Skip a target with --skip pyproject / --skip init / --skip plugin / --skip marketplace / --skip docs.

A pip install -e . --no-deps before the suite/dos doctor step keeps the editable install's metadata current, so dos.__version__ reports the freshly bumped value rather than the prior release's — without it, the version-drift guard (tests/test_docs_version_drift.py) reads stale metadata and can pass against stale docs, the exact mask that hid the v0.19.0 drift.

Step 5: Commit

Stage only the snapshot + the version-marker files + the FTUE doc/skill files the sweep touched + the new release notes, with every path explicit, then commit scoped by the same explicit pathspec — the race-safe form on this hot tree (Step 1.5 conventions). Use the bumper's JSON report (targets.docs.files_swept) as the authoritative list of which doc/skill paths actually changed — stage only those, plus the regenerated bundle copies under claude-plugin/skills/:

git add pyproject.toml src/dos/__init__.py \
        claude-plugin/.claude-plugin/plugin.json .claude-plugin/marketplace.json \
        <doc/skill paths from targets.docs.files_swept ...> \
        claude-plugin/skills/ \
        docs/releases/vX.Y.Z.md <snapshot paths...>
git commit -m "vX.Y.Z: <one-line summary>" -- \
        pyproject.toml src/dos/__init__.py \
        claude-plugin/.claude-plugin/plugin.json .claude-plugin/marketplace.json \
        <doc/skill paths from targets.docs.files_swept ...> \
        claude-plugin/skills/ \
        docs/releases/vX.Y.Z.md <snapshot paths...>

Why the pathspec on git commit (not just on git add): a bare git commit commits whatever is in the index — and on this tree a concurrent session may have staged its own files between your git add and your commit, which a bare commit would then ship under your vX.Y.Z: subject (feedback-shared-index-bare-commit-grabs-concurrent-staged). Naming the paths on the commit scopes it to your release. (The pathspec re-reads the working tree for those paths, which is exactly what you want here — your snapshot paths are yours; the Step 1.6 lease defer already removed any path a sibling loop owns. If one of your snapshot paths is also being edited unstaged by a sibling, that's the hot interleaved-file case — handle it with the patch→reset→apply recipe from Step 1.5 or hold the file out and note it.)

Before git add, re-run git status --porcelain and compare against the snapshot. Any path that appeared since Step 1 and isn't in the snapshot → leave it alone, note in the final summary. Full rules in runbook "Snapshot discipline".

Generated pairs are staged from the same source bytes — never across a time gap (docs/295 P2, the v0.23.2 scar). A generated artifact and its source (claude-plugin/skills/ ← src/dos/skills/; README.md ← docs/readme/) must enter the commit coherent, and on this hot tree a sibling can edit the source between your regeneration and your commit. Two safe forms:

• Regenerate-in-the-same-breath: run build_plugin.py / build_readme.py immediately before the git add+git commit call — same Bash invocation, no tool calls in between.
• Index surgery (when the source file is dirty with a sibling's hunks): build the index entry from known bytes, bypassing the working tree — git show HEAD:<f> | <transform> | git hash-object -w --stdin then git update-index --cacheinfo 100644,<sha>,<f> — and commit the INDEX (bare git commit, no pathspec) after a final git status --porcelain check that nothing foreign is staged. This is how v0.23.3 cut clean while two generated pairs were mid-edit around it.

Do NOT add a Co-Authored-By line. Do NOT stage gitignored paths.

Step 5.5: Rebuild the bundled plugin binaries (only if Go source changed)

The Claude Code plugin ships its native dos-hook fast-path binaries committed in claude-plugin/bin/ (docs/125 GHF4) so a marketplace install is a direct install — a clone already has the binary for the user's arch. So a release that touched the Go source (go/**) must re-commit fresh binaries, or the published plugin ships a stale fast-path. Skip this step entirely if the release did not touch go/.

# Only if `go/` changed in this release AND the Go toolchain is on PATH:
python scripts/build_hook_binary.py        # rebuilds the full amd64+arm64 × lin/mac/win matrix
git status --porcelain claude-plugin/bin/   # did any binary actually change?

If — and only if — a binary changed, commit it by explicit pathspec (same race-safe form as Step 5), e.g.:

git add claude-plugin/bin/dos-hook-*
git commit -m "build(dos-hook): rebuild bundled native binaries for vX.Y.Z" -- claude-plugin/bin/dos-hook-*

• No Go toolchain on this machine? Skip and note it: the committed binaries stay as-is (still valid for an unchanged go/); a CI matrix or a follow-up rebuild refreshes them. tests/test_hook_binaries_bundled.py still passes (presence + tracking), but a go/-changed release without a rebuild ships a stale fast-path — call that out in the summary.
• The binaries are large (~24 MB total) and reproducible (-trimpath, CGO_ENABLED=0): an unchanged go/ rebuilds to byte-identical output, so git status shows nothing and there is nothing to commit — the common case.

Step 5.9: Pre-tag witness — run the release-killers while nothing is immutable yet

Cheap, deterministic, hot-tree-safe: the exact test families that killed v0.23.0/v0.23.1/v0.23.2 (issue #7) run in seconds and read only content this release itself just wrote. Run them after the Step 5 commit (the Step 4 pip install -e . --no-deps must already have happened), BEFORE Step 6:

python -m pytest -q tests/test_workflow_yaml_parses.py tests/test_docs_version_drift.py \
       tests/test_readme_assembly.py tests/test_canonical_example_lockstep.py \
       tests/test_plugin_manifest.py

• Green → proceed to Step 6.
• Red → fix it now, as a follow-up commit before any tag exists — the version number hasn't been spent yet, which is the whole point of running this here.
• The subset deliberately excludes the hot-tree false-positive families (test_workspace_config etc.) so it stays trustworthy on a tree a sibling loop is editing. It complements — never replaces — the full-matrix CI verdict Step 6 waits for.

The stronger form — adjudicate the COMMIT, not the tree (docs/295 P2). The quick run above reads the working tree, which on this machine may differ from the bytes you just committed (a sibling's unstaged hunk reads as your red — or your green). scripts/release_dry_run.py runs the same witness against the committed bytes, in a detached worktree + scratch venv (isolated from both the hot tree and the machine's editable install — its first live run caught a sibling's mid-flight version bump skewing every drift test):

python scripts/release_dry_run.py --fast     # the release-perturbation set vs HEAD's commit (~40s)
python scripts/release_dry_run.py            # the FULL suite vs the commit (~5 min) — isolation
                                             # makes even the hot-tree families trustworthy

Exit 0 → Step 6 (it prints a release-dry-run: pass … trailer — carry it into the tag annotation, docs/295 P3). Exit 1 → fix forward, re-run, then tag. Prefer this form whenever the tree is visibly hot (git status shows sibling work); prefer the full mode when the release touched code, not just docs.

Step 6: Push → wait for the CI verdict → only then tag (tag-after-green)

The tag is the one artifact you can never take back (v* and stable/* are ruleset-immutable, and PyPI will only ever accept each version once) — and the publish gate refuses any SHA without a green CI run. So a tag pushed before its CI verdict exists is a bet, and on 2026-06-10 that bet lost three version numbers in one day (v0.23.0/1/2 — issue #7). Push the commit, let CI rule, then tag:

git push origin master                                  # 1. the release commit goes up alone
sha=$(git rev-parse HEAD)                               #    (your release commit — pin it now)
ci=$(gh run list --workflow ci.yml --commit "$sha" --json databaseId --jq '.[0].databaseId')
gh run watch "$ci" --interval 30                        # 2. wait for the verdict (~5–10 min)
gh run view "$ci" --json conclusion                     #    confirm "success" EXPLICITLY — a pipe's
                                                        #    exit code is the tail's, not gh's
git tag -a vX.Y.Z "$sha" -m "vX.Y.Z" \
        -m "<release-dry-run trailer from Step 5.9, if it ran>"   # 3. tag only the witnessed-green SHA
git push origin vX.Y.Z

• CI green → tag and push the tag. publish.yml's own ci-green gate then finds the verdict already recorded and proceeds straight to the approval hold — the wait moved earlier; total wall-clock is unchanged.
• CI red → no tag. Fix forward on master and re-run from Step 5.9; the version number is saved. (Step 5.9 should have caught a deterministic killer already — a red here is usually a matrix-leg or integration failure your box doesn't reproduce.)
• A sibling pushed meanwhile → your release commit may no longer be HEAD. Fine: the --commit "$sha" filter watches the run on YOUR commit, and the tag names "$sha" explicitly — never tag whatever HEAD drifted to.
• If git push rejects because the remote has commits you don't have, rebase your single commit on top — do NOT force-push master.

If you cut this release from a feature branch (the git status may show e.g. feat/<x>), confirm with the operator before pushing the branch to master, OR push the branch + tag and open a PR instead. The default trunk is master (see the feedback-stay-on-master-by-default memory) — return to it after the branch merges. Do not silently retarget a push.

What the push sets in motion (post-cutover — check, don't assume):

• The pre-push leak gate runs first, locally, on both pushes (fail-closed — see the public-repo note up top). A refusal means scrub + amend, never --no-verify; a missing scanner means re-sync it from ../dos-private/tools/leak_scan.py.
• The master push fires ci.yml (leak-scan + lint always; the docs-aware test matrix — full 4-leg grid for code, 2-leg for prose; per-platform wheel build + binary-format guard on code changes) and the repo-self DOS gate (dos-gate.yml: commit-audit + verify via the bundled verify-action).
• The tag push fires publish.yml (Step 7.4): with tag-after-green it finds the CI verdict already recorded and proceeds straight to the pypi-environment approval hold. (Its ci-green poll remains the backstop for an out-of-order or manual tag: a RED SHA is refused — then fix forward and cut the next patch release; never re-point or delete a pushed tag.)

Read the verdicts rather than assuming them:

gh run list --commit "$(git rev-parse HEAD)"     # ci.yml + dos-gate.yml on the release SHA
gh run list --workflow publish.yml --limit 1     # the publish run (ci-green poll / approval hold)

Step 7: GitHub release

gh release create vX.Y.Z --title "vX.Y.Z" --notes "$(cat docs/releases/vX.Y.Z.md)"

The GH release carries no uploaded assets — the dist ships through PyPI, not as GH-release attachments. The dist is no longer pure-Python (docs/286): publish.yml builds one wheel per OS/arch, each embedding its native dos-hook fast-path binary at dos/_bin/, plus a pure-source sdist — all CI-built; this skill builds nothing locally. The install path is pip install dos-kernel (live on PyPI since 2026-06-10; dos-kernel==X.Y.Z pins this tag), or pip install -e . from a checkout. The distribution name is dos-kernel — not dos, which on PyPI is an unrelated package (the import name stays dos). There is no release.py, no archive prune, no versioned install snapshot, no screenshots. (The claude-plugin/bin/ binaries are NOT a GH-release asset either — they ship committed in the git tree, rebuilt at Step 5.5; they are a separate surface from the wheel's embedded binary.)

Step 7.4: Surface the PyPI publish run (the pipeline is already in flight)

dos-kernel is live on PyPI (first published 2026-06-10 via the pending trusted publisher that claimed the name — publish.yml's header records the one-time setup). Publishing is no longer a local twine act: the Step 6 tag push **
