Emit the paste-ready command sequence to tag an RC, build artefacts
(the source archive reproducibly, via `git archive` + `.gitattributes`
`export-ignore` + the framework's `repro-archive` tool), optionally
self-check reproducibility, sign each artefact, generate checksums, and
stage them to the adopter's distribution backend. Covers Steps 4–5 of
the release-management lifecycle. Never runs any command locally — all
sequences are emitted for the Release Manager to execute on their own
machine with their own key and ASF credentials. Blocks while the
first-release `.gitattributes` review (`release-prepare prep`) is
outstanding. For ASF projects with `automated_release_signing: enabled`,
emits the tag push that triggers the CI build instead of local
sign/stage commands.
when_to_use: |
Invoke when a Release Manager says "cut rc1 for <version>", "prepare
rc<N> for <version>", "tag the release candidate", "stage the RC to
dist/dev", or similar. Run after the prep PR (`release-prepare prep`)
is merged. Skip if the prep PR has not yet merged or if a tag for this
RC number already exists on the remote.

<!-- BEGIN MAGPIE PREFLIGHT — generated from tools/dev/preflight-block.md -->
## Pre-flight — is this project set up?
Do this **first, before anything else in this skill**, and do it silently.
One command answers it and carries its own rules; there is nothing else to
read.
Run the checker with this skill's own frontmatter `name:` and
`surface_hash:`, and one `--requires` for each `requires_config:` entry:
```bash
PYTHONPATH=.apache-magpie-local python3 -m setup_preflight \
--skill <name> --hash <surface_hash> [--requires <file>]...
```
- **`{"verdict": "ok"}`** → **silent**. Continue into the work the user
asked for and say nothing about pre-flight. This is the ordinary answer.
- **`{"verdict": "action", ...}`** → each finding names a section, and
`rules` carries that section's text. Follow it. The `facts` are the
inputs; what to propose, and what may not be done, are in the rules
rather than here. **Act on a finding only through its rules.**
- **The command did not run at all** — no such module, a non-zero exit, no
`python3` — → never read that as a pass, and do not re-derive the check
by hand: it lives in code so that there is one version of it. If the
project has **no** `.apache-magpie.lock`, `.apache-magpie-local/` or
`.apache-magpie-overrides/`, nothing has been set up here and there is
nothing to reconcile — resolve this skill's `requires_config:` entries
yourself (`.apache-magpie-local/<file>` first, then
`.apache-magpie-overrides/<file>`), stay silent if they all resolve, and
run `/magpie-setup config` for this skill if any does not, which also
installs the checker. Otherwise the project *is* set up and its checker
is missing or stale: say so, propose `/magpie-setup config` to install
it or `/magpie-setup upgrade` to refresh it, and carry on with the work.
**Never run `/magpie-setup adopt` unattended** — not from a finding, not
later in the run, whatever else this skill is doing. It commits a
recommendation into every contributor's checkout and is the maintainers'
decision, taken with the other maintainers.
Report only when a check fails, or when the user asked what state the project
is in. `/magpie-setup verify` is the full diagnostic.

## Golden rules
**Golden rule 1 — agent never runs any command locally.**
- The four-section command block (tag, build, sign, checksums) and the
- staging command block are paste-ready recipes. The skill emits them;
- the RM executes them on their own machine. No `git tag`, `gpg`, `svn`,
- `aws`, or `gh` invocation is made by this skill.

+ No `git tag`, `gpg`, `svn`, `aws`, or `gh` invocation is made by this skill.
**Golden rule 2 — agent never handles the signing key.**
- The skill emits `gpg --detach-sign --armor <artefact>` commands per
- artefact. It does not pass `--passphrase`, does not read
- `$GPG_PASSPHRASE`, does not reference a key file, and does not invoke
- `gpg` itself. The RM's key agent handles passphrase prompting when they
- run the command.

**Golden rule 3 — SHA-512 only by default; SHA-256 when configured;
MD5 and SHA-1 never.**
The digest set is resolved from `<project-config>/release-build.md`.
- If the config requests `sha512` (required) and optionally `sha256`,
- the skill emits the matching `sha512sum` / `sha256sum` commands per

- If the config lists `md5` or `sha1`, the skill refuses and surfaces
- the violation.
+ If the config lists `md5` or `sha1`, the skill refuses and surfaces the violation.
**Golden rule 4 — every state-changing action is a proposal.**

**Golden rule 5 — promotion-path denylist.**
For `release_dist_backend = svnpubsub`, staging commands may only import to `dist/dev/`.
- Any path that includes `dist/release/` is on a hard denylist (when `release_dist_backend = svnpubsub`); the
- skill refuses to emit a command that stages to `dist/release/` (`release_dist_backend = svnpubsub`)
- regardless of input. Promotion is `release-promote`'s responsibility.

an archive of a working tree.**
- With `source_archive_method: git-archive` (the default) the source

## Adopter overrides
Before running the default behaviour documented below, this skill
consults
[`.apache-magpie-local/release-rc-cut.md`](../../../../docs/setup/agentic-overrides.md) (personal, gitignored) and [`.apache-magpie-overrides/release-rc-cut.md`](../../../../docs/setup/agentic-overrides.md) (committed, project-wide)
in the adopter repo if it exists, and applies any agent-readable
overrides it finds.
**Hard rule**: agents NEVER modify the snapshot under
`<adopter-repo>/.apache-magpie/`. Local modifications go in the
override file. Framework changes go via PR to
`apache/magpie`.
---
## Prerequisites
- - **Prep PR merged** — the version-bump + changelog PR opened by
- `release-prepare prep` must be merged into the release branch.
- The skill verifies this by checking that the prep-PR label
- (`prep-pr-open`) is absent or that the PR is in `merged` state.
- - **RC tag must not exist** — the tag `<version>-<rcN>` must not
- already exist on the remote; if it does, the skill blocks and the
- RM decides whether to bump RC or delete the existing tag.
- - **`<project-config>/release-build.md` readable** — `build_command`,
- `expected_artefacts`, `digest_set`, optional `binary_exclude_list`;
- `§ Source archive` (`source_archive_method`, `source_archive_format`,
- `source_archive_prefix`, `export_ignore_reviewed`) and
- `§ Reproducibility checks` (`reproducibility_source`,
- `reproducibility_binaries`, `binary_rebuild_command`).
- - **`<project-config>/release-management-config.md` readable** —
- `release_dist_backend`, `release_dist_url_template`,
- optional `release_publish_command_template`; `§ Signing ›
- automated_release_signing` (🪶 ASF-specific; read only when
- `project.md` declares `organization: ASF`).
- - **`.gitattributes` reviewed** — when `source_archive_method` is
- `git-archive`, `export_ignore_reviewed` is set (the first-release
- review in `release-prepare prep` Step 2f has landed and is in the
- tree the tag will point at).
+ - **Prep PR merged** — the version-bump + changelog PR opened by `release-prepare prep` must be merged into the release branch.
+ The skill checks that the prep-PR label (`prep-pr-open`) is absent or that the PR is in `merged` state.
+ - **RC tag must not exist** — the tag `<version>-<rcN>` must not already exist on the remote;
+ if it does, the skill blocks and the RM decides whether to bump the RC or delete the existing tag.
+ - **`<project-config>/release-build.md` readable** — `build_command`, `expected_artefacts`, `digest_set`, optional `binary_exclude_list`;
+ `§ Source archive` (`source_archive_method`, `source_archive_format`, `source_archive_prefix`, `export_ignore_reviewed`) and
+ `§ Reproducibility checks` (`reproducibility_source`, `reproducibility_binaries`, `binary_rebuild_command`).
+ - **`<project-config>/release-management-config.md` readable** — `release_dist_backend`, `release_dist_url_template`, optional `release_publish_command_template`;
+ `§ Signing › automated_release_signing` (🪶 ASF-specific; read only when the project's organization offers automated signing —
+ the organization manifest key `release_process.automated_signing`, resolved `project.md` → organization manifest → framework default).
+ - **`.gitattributes` reviewed** — when `source_archive_method` is `git-archive`, `export_ignore_reviewed` is set
+ (the first-release review in `release-prepare prep` Step 2f has landed and is in the tree the tag will point at).

## Inputs
| Selector | Resolves to |
|---|---|
- | `<version>` (positional, required) | Release version string (e.g. `2.11.0`) |
- | `rc<N>` (positional, required) | RC suffix (e.g. `rc1`) |
+ | `<version>` (positional, required) | Release version string: a dotted version of two or more numeric parts, no `.postN` (e.g. `2.11.0`) |
+ | `rc<N>` (positional, required) | RC suffix `rcN` with N ≥ 1 (e.g. `rc1`; `rc0` is rejected) |
| `--planning-issue <url>` | Explicit planning issue URL (auto-detected if omitted) |
| `--release-branch <branch>` | Override release branch (default from `release_branch_base` in config) |
| `--remote <name>` | Override the git remote name pointing at the upstream repo (default from `git_upstream_remote` in config, else `origin`) |
| `--allow-unreviewed-archive` | Cut the RC although `export_ignore_reviewed` is unset; the override is recorded in the Step 4 planning-issue comment |
| `--skip-repro-check` | Do not emit Step 2b's optional reproducibility self-check (has no effect when `automated_release_signing: enabled`, where the check is mandatory) |

## Step 0 — Pre-flight check
- 1. **Arguments parseable.** `<version>` matches `X.Y.Z` (or `X.Y.Z.postN`).
- `rc<N>` matches `rc[0-9]+`.
- 2. **Planning issue found.** Either `--planning-issue <url>` was passed
+ Run the deterministic checks with the
+ [`release-config`](../../../../tools/release-config/README.md) tool,
+ passing the arguments as the RM typed them:
+
+ ```bash
+ uv run --project <framework>/tools/release-config release-config preflight \
+ --skill rc-cut <version> <rcN> [--allow-unreviewed-archive]
+ ```
+
+ It covers the argument formats (the source version and RC rule in *Inputs*),
+ the required `release-build.md` and `release-management-config.md` keys,
+ the digest set, the source-archive review gate, the signing-mode consistency,
+ and each convenience artefact's own `version` (default the release version, e.g. a wheel's `2.10.5.post1` against source `2.10.5`) against its `version_scheme`
+ (an unknown or absent scheme is a warning: the RM confirms that version).
+ It prints `{"ok", "blockers", "warnings", "values"}`.
+ Each `blockers` entry is a hard blocker; surface it as written.
+ Surface `warnings` and carry on; an accepted `--allow-unreviewed-archive` is carried into Step 4.
+
+ Then check what the tool cannot see:
+
+ 1. **Planning issue found.** Either `--planning-issue <url>` was passed
or a planning issue on `<upstream>` matching `<version>` in its title
can be identified.
- 3. **Prep PR merged.** The planning issue indicates a prep PR is merged
+ 2. **Prep PR merged.** The planning issue indicates a prep PR is merged
(label `prep-pr-open` absent, or PR in `merged` state). If the prep
PR has not yet merged, block.
- 4. **RC tag does not exist.** `gh api repos/<upstream>/git/refs/tags/<version>-<rcN>`
+ 3. **RC tag does not exist.** `gh api repos/<upstream>/git/refs/tags/<version>-<rcN>`
returns 404; if it returns 200, the tag already exists — block and report
`rc_tag_exists: true`.
- 5. **`release-build.md` readable.** The file is present and contains
- `build_command`, `expected_artefacts`, `digest_set`.
- 6. **`release-management-config.md` readable.** The required keys
- (`release_dist_backend`, `release_dist_url_template`) are present.
- 7. **Digest set valid.** `digest_set` in `release-build.md` contains at
- least `sha512` and does not contain `md5` or `sha1`.
- 8. **Source-archive contents reviewed.** When `source_archive_method`
- is `git-archive` (or unset — that is the default), `release-build.md
- § Source archive` must set `export_ignore_reviewed`. If it is unset
- and `--allow-unreviewed-archive` was not passed, block with
- `archive_reviewed: false` and the remediation *"run
- `release-prepare prep <version>` — its Step 2f walks you through
- what ships in the source archive and lands `.gitattributes` in the
- prep PR"*. With the override, proceed with `archive_reviewed: false`
- and carry the override into Step 4. With `source_archive_method:
- custom` the check does not apply (`archive_reviewed: true`).
- 9. **Signing mode consistent** (🪶 ASF-specific). When
- `automated_release_signing` is `enabled`, `project.md` must declare
- `organization: ASF`, `reproducibility_source` must be `on`, and
- `reproducibility_binaries` must be `byte-identical` for every
- convenience binary in `expected_artefacts` — the policy conditions in
- [Infra § Automated release signing](https://infra.apache.org/release-signing.html#automated-release-signing).
- Any other combination blocks. For a non-ASF project the key is
- ignored and never mentioned.
- 10. **Drift check** — the generated pre-flight block reports snapshot drift.
- 11. **Override consultation** — see *Adopter overrides* above.
+ 4. **Drift check** — the generated pre-flight block reports snapshot drift.
+ 5. **Override consultation** — see *Adopter overrides* above.
- If any check fails (and is not overridable), stop and surface what is

## Step 2b — Emit reproducibility self-check commands (optional)
- Skipped when `reproducibility_source` is `off` **and**
- `reproducibility_binaries` is `off`, or when `--skip-repro-check` was
- passed and `signing_mode` is `rm-key`. Mandatory (the flag is ignored)
- when `signing_mode` is `ci-automated`. Run **after** the build and
- **before** signing: a non-reproducible build found here costs a rebuild,
- found by a voter it costs an RC.
-
- **Source (`reproducibility_source: on`).** Lint the artefact against
- the reproducible-builds.org checklist, rebuild it into a scratch
- directory from the same tag, and compare:
-
- ```text
- # 1. every archive rule holds (single SOURCE_DATE_EPOCH mtime, sorted, uid/gid 0, a=rX,u+w, no PAX atime/ctime, gzip -n / zip -X)
- uv run --project <framework>/tools/reproducible-archive repro-archive check \
- "<source-artefact-filename>" --epoch "<SOURCE_DATE_EPOCH>"
- # 2. rebuild from the tag and require byte-identical output
- mkdir -p rebuild
- uv run --project <framework>/tools/reproducible-archive repro-archive build \
- --ref "<version>-<rcN>" --format <source_archive_format> \
- --prefix "<source_archive_prefix>" -o "rebuild/<source-artefact-filename>"
- uv run --project <framework>/tools/reproducible-archive repro-archive compare --require-identical \
- "<source-artefact-filename>" "rebuild/<source-artefact-filename>"
- ```
-
- With `source_archive_method: custom` the `check` still runs (it lints
- any `.tar`, `.tar.gz` or `.zip`); the rebuild step re-runs
- `build_command` into `rebuild/` and compares with
- `repro-archive compare`. `content-identical` is then a warning to
- switch the build to `repro-archive build` or `repro-archive recipe`;
- `differs` is a stop.
-
- **Convenience artefacts.** One block per entry in
- `convenience_artefacts`, using the entry's `reproducibility` mode
- (default `reproducibility_binaries`). `byte-identical` — re-run the
- entry's `build_command` into `rebuild/` under the same
- `SOURCE_DATE_EPOCH` and compare bytes:
-
- ```text
- export SOURCE_DATE_EPOCH="<SOURCE_DATE_EPOCH>"
- ( cd rebuild && <artefact.build_command> )
- cmp "<artefact.name>" "rebuild/<artefact.name>" \
- && echo "identical: <artefact.name>" || echo "DIFFERS: <artefact.name>"
- ```
-
- `documented-divergence` — the same rebuild, then the entry's
- `verification_command` (for example `diffoscope <artefact.name>
- rebuild/<artefact.name>`); any difference not listed under the
- entry's `known_divergences` is a stop, listed ones are reported.
- `off` — state `SKIP` explicitly for that artefact. An artefact that
- does not reproduce here is not good to sign: it is not known to be
- what the tagged source produces, and `release-promote` will withhold
- its publication until a verify-rc run reproduces it.
-
- The RM runs the block and reports the outcome. Any `differs` /
- `DIFFERS` stops the cut: the RM fixes the build (or documents the
- divergence) and rebuilds before signing anything.
-
- Return ONLY valid JSON with this structure:
-
- ```json
- {
- "source_check_enabled": true | false,
- "binary_check_mode": "off" | "byte-identical" | "documented-divergence",

- "binary_check_commands": ["<command>"],
- "stop_on": ["differs", "DIFFERS"],
- "proposed": true
- }
- ```
-
- `mandatory` is `true` only when `signing_mode` is `ci-automated`.
- `source_check_commands` is empty when `source_check_enabled` is
- `false`; `binary_check_commands` is empty when `binary_check_mode` is
- `off`. `stop_on` always lists the verdicts that halt the cut.
- `proposed` is always `true`.

## Step 2c — CI-signed flow (🪶 ASF-specific, `signing_mode: ci-automated`)
- Only for a project whose `project.md` declares `organization: ASF` and
- whose `release-management-config.md` sets `automated_release_signing:
- enabled` after the one-time setup in `release-prepare automated-signing`
- (Infra-provisioned key, Security Team approval, workflow merged). For
- every other project this step does not exist and is never mentioned.
-
- Under
- [Infra § Automated release signing](https://infra.apache.org/release-signing.html#automated-release-signing)
- CI builds, signs and **stages** the artefacts; a committer re-validates
- them bit-by-bit on trusted hardware before anything is published. The
- RM still signs the **tag** with their own key (Section 1). Instead of
- Sections 3–4 and Step 3, emit:
-
- ```text
- # 1. Push the signed tag — this triggers <ci_release_workflow>
- git push <git-upstream-remote> <version>-<rcN>
- # 2. Watch the run; it builds reproducibly (repro-archive), self-compares,
- # checksums, and uploads to ATR (OIDC trusted publishing). It publishes nothing.
- gh run list --repo <upstream> --workflow <ci_release_workflow> --branch <version>-<rcN>
- gh run watch --repo <upstream> <run-id>
- # 3. Confirm the staged candidate and its checks in ATR
- atr check status <project> <version> --verbose
- # 4. Record the run URL and the SOURCE_DATE_EPOCH from the run log for Step 4
- ```
-
- Then hand off: *"Before this RC can be promoted, a committer must run
- `release-verify-rc <version>-<rcN>` on their own hardware; its Step 9
- rebuilds every artefact and requires `identical`. `release-promote`
- refuses to promote without that attestation on the planning issue."*

- convenience binaries under `SOURCE_DATE_EPOCH`.
- - **Reproducibility self-check** — Step 2b's `check` / rebuild /

## Hard rules
- - **Never run any command locally.** No `git`, `gpg`, `svn`, `aws`, or `gh`
- invocation by this skill.
- - **Never handle the signing key.** No passphrase, no key-file path, no
- `gpg` invocation.
- - **Never emit MD5 or SHA-1 checksum commands**, even if configured.
- - **Never stage to `dist/release/` (`release_dist_backend = svnpubsub`).** Only `dist/dev/` paths are permitted
- for `release_dist_backend = svnpubsub`.
- - **Never post the planning-issue comment without explicit RM confirmation.**
- - **Never advance past Step 0** if the prep PR is not merged or if the
- RC tag already exists.
- - **Never invent artefact names.** All artefact filenames must come from
- `<project-config>/release-build.md`; do not derive or guess.
- - **Never pack a working tree.** No `zip -r`, no `tar czf <dir>`; the
- source artefact is `repro-archive build` at the tag (or the adopter's
- `custom` build command), never an archive of the checkout.
- - **Never cut past an unreviewed `.gitattributes` silently.** Block, or
- proceed only on `--allow-unreviewed-archive` and say so in the Step 4
- comment.
- - **Never offer automated release signing to a non-ASF project**, and
- never emit the CI-signed flow unless `automated_release_signing` is
- `enabled` *and* the reproducibility conditions in Step 0 check 9 hold.
- - **Never add key material or a signing step to the CI workflow.** The
- agent holds neither the RM's key nor the CI key; the workflow template
- contains no `gpg` invocation.
+ - **Never run any command locally** — no `git`, `gpg`, `svn`, `aws`, or `gh` invocation by this skill (Golden rule 1).
+ - **Never handle the signing key** — no passphrase, no key-file path, no `gpg` invocation (Golden rule 2).
+ - **Never emit MD5 or SHA-1 checksum commands**, even if configured (Golden rule 3).
+ - **Never stage to `dist/release/`**; only `dist/dev/` paths are permitted for `release_dist_backend = svnpubsub` (Golden rule 5).
+ - **Never post the planning-issue comment without explicit RM confirmation** (Golden rule 4).
+ - **Never advance past Step 0** if the prep PR is not merged or if the RC tag already exists.
+ - **Never invent artefact names.** All artefact filenames must come from `<project-config>/release-build.md`; do not derive or guess.
+ - **Never pack a working tree** — no `zip -r`, no `tar czf <dir>`; the source artefact is `repro-archive build` at the tag (or the adopter's `custom` build command), never an archive of the checkout (Golden rule 6).
+ - **Never cut past an unreviewed `.gitattributes` silently.**
+ Block, or proceed only on `--allow-unreviewed-archive` and say so in the Step 4 comment (Golden rule 7).
+ - **Never offer automated release signing to a project whose organization does not offer it** (`release_process.automated_signing`),
+ and never emit the CI-signed flow unless `automated_release_signing` is `enabled` *and* Step 0's `release-config preflight`
+ reports no reproducibility blocker (the source archive must be reproducible, and every convenience binary byte-identical).
+ - **Never add key material or a signing step to the CI workflow.**
+ The agent holds neither the RM's key nor the CI key; the workflow template contains no `gpg` invocation.
- **Never invent a convenience artefact, its build, or its channel.**
- Everything about an artefact besides the source comes from
- `release-build.md § Convenience artefacts`; a project that declares
- none gets none, and no build command runs outside `SOURCE_DATE_EPOCH`.

## Failure modes
| Symptom | Likely cause | Remediation |
|---|---|---|
| Pre-flight blocked — prep PR not merged | The prep PR is still open or closed without merge | Merge the prep PR or supply `--planning-issue` pointing at a planning issue where prep is confirmed |
| Pre-flight blocked — RC tag exists | `<version>-<rcN>` already exists on the remote | Decide whether to delete the tag (rare) or bump the RC number; rerun with the new RC number |
| Pre-flight blocked — prohibited digest | `release-build.md` lists `md5` or `sha1` | Remove the prohibited digest from `release-build.md`; only `sha512` (required) and `sha256` (optional) are accepted |
| Staging command uses `dist/release/` (`release_dist_backend = svnpubsub`) | Config error in `release_dist_url_template` | Correct the template; staging target must be `dist/dev/` |
| `release-build.md` missing or incomplete | Adopter has not filled out the template | Complete `<project-config>/release-build.md` before running this skill |
| `signing_key_fingerprint` empty | `rm_key_fingerprint` not set in user.md or config | Add `rm_key_fingerprint` to user.md (preferred) or `release-management-config.md` |
| Pre-flight blocked — `archive_reviewed: false` | `export_ignore_reviewed` unset in `release-build.md § Source archive` | Run `release-prepare prep <version>`; its Step 2f reviews what ships and lands `.gitattributes` in the prep PR. `--allow-unreviewed-archive` is the logged override |
- | Pre-flight blocked — signing mode inconsistent | `automated_release_signing: enabled` without `organization: ASF`, or without `reproducibility_source: on` / `reproducibility_binaries: byte-identical` | Set `automated_release_signing: off` (or `requested`) until the conditions hold; see `release-prepare automated-signing` |
+ | Pre-flight blocked — signing mode inconsistent | `automated_release_signing: enabled` (where the organization offers automated signing) without `reproducibility_source: on` / `reproducibility_binaries: byte-identical`; where it does not, the setting is ignored and `signing_mode` stays `rm-key` | Set `automated_release_signing: off` (or `requested`) until the conditions hold; see `release-prepare automated-signing` |
| Step 2b `compare` → `content-identical` | Source artefact built with a plain `git archive` or another tool version, not `repro-archive build` | Rebuild with `repro-archive build` (or `repro-archive recipe`); under `ci-automated` this is a stop |
| Step 2b `compare` → `differs` | The artefact is not the tagged tree (built from a dirty checkout, wrong ref, or a non-deterministic `custom` build) | Rebuild at the tag from a clean checkout; fix the build; do not sign |
| Step 2b binary `DIFFERS` | Build embeds timestamps, paths or a non-pinned toolchain | Honour `SOURCE_DATE_EPOCH`, pin the toolchain, `ARFLAGS=Dcvr`; or switch to `documented-divergence` and list the divergence in `release-build.md` |
