feat(release): push the version bump through a dedicated release deploy key - #2290
Conversation
…oy key The v2.29.0 release died at `git push origin main`. `main` and `preview` carry rulesets requiring a pull request, and the admin bypass is `bypass_mode: "pull_request"` — enough to merge a PR, not enough to push. The release had to be finished by hand-flipping the ruleset bypass to `always`, pushing, and restoring it afterwards. Automating that flip was the obvious fix and is the wrong one. It is crash-open: once GitHub accepts the widened ruleset, a SIGKILL, a lost network, or a hung push leaves protection off with no lease to expire it, and while the window is open the bypass applies to every holder of the admin role rather than to this one release. It would also make the release script an administrator of its own security control. A dedicated write deploy key registered as a `DeployKey` bypass actor fails closed instead. Protection is never weakened, process death cannot leave the branch open, concurrent releases cannot corrupt ruleset configuration, and the carve-out is revoked by deleting one credential rather than by editing repository configuration. The key is opt-in by path: without `OCX_RELEASE_SSH_KEY` the push is byte-identical to before, so a contributor or CI clone is unaffected. It is selected for this one push and nothing else — the `origin` remote stays HTTPS, so no other command inherits it. `IdentitiesOnly=yes` is load-bearing: an ssh-agent holding the maintainer's key would otherwise authenticate as the maintainer and be rejected by the ruleset again. Design credit: an adversarial review rejected the ruleset-toggle approach on the crash-open argument above and named the deploy key as the materially safer mechanism.

Git parses GIT_SSH_COMMAND with shell-style word splitting instead of exec'ing it, so a bare interpolation splits on any key path containing a space. The Windows default is exactly that shape -- C:\Users\Jun Kim\.ssh\... -- and ssh would read the tail as its next flag, failing the protected push on the one platform the release helper already has a history of breaking on. Quote with double quotes rather than single: both POSIX shells and Git's own Windows parser accept them, and they do not mangle a backslash path. Escape the characters that stay special inside double quotes so a path can never introduce a second word or a substitution. The existing test used toContain() with a shell-safe Unix path, which passes on the broken form. It now asserts the whole command string, and a second case pins a path carrying both spaces and backslashes. Both were driven red against the unquoted interpolation. Caught by adversarial review round 2.
…oding it The hardcoded scp-like remote tripped privacy:scan, which correctly cannot tell `user@host:owner/repo.git` from an email address -- CI gates failed on it. Deriving the target from the configured `origin` URL fixes more than the scan: a hardcoded upstream slug would have made a fork's release push to the upstream repository. OCX_RELEASE_SSH_REPO still wins when a maintainer needs an explicit target, and an origin that yields no usable SSH target now fails loudly instead of pushing somewhere unintended. Adds a regression test pinning that a fork's origin produces a fork target, plus a git shim for `remote get-url`.

Exercise GIT_SSH_COMMAND instead of checking only its text.
The test checks the generated string, but the fake Git shim at Line 65 never executes that command. The test therefore does not prove that Git passes the key path to ssh as one argument. Git shell-interprets GIT_SSH_COMMAND, so add a fake SSH executable and assert its received arguments through the actual Git path. (git-scm.com)

Requesting changes on exact head 7a6d9c23f69600ac5791ec7c7a617c7b26c4effe.
The focused release-helper suite passes 17/17, repository typecheck passes, privacy scan passes, and the exact-head GitHub checks are green. Those results do not cover the remaining release credential/transport boundaries below.
OCX_RELEASE_SSH_REPOis accepted verbatim. A configured HTTPS URL therefore ignoresGIT_SSH_COMMANDand can push with ambient HTTPS credentials. Validate the explicit value as an SSH transport before entering deploy-key mode; reject HTTPS, local paths, and other non-SSH forms.- The quoting regression still inspects only the recorded
GIT_SSH_COMMANDstring. The fake git shim never lets Git parse and invoke SSH, so it does not prove that whitespace, backslashes, semicolons, dollar substitutions, backticks, and quotes reachssh -ias one argument on the supported platforms. Exercise a real Git-to-fake-SSH path and assert the fake SSH argv. runRelease()inheritsOCX_RELEASE_SSH_KEY,OCX_RELEASE_SSH_REPO,GIT_SSH_COMMAND, andFAKE_GIT_PENDING_BUMPfrom its parent. The no-key/default-path tests can therefore silently take a different branch under the real release environment. Remove these variables before applying scenario overrides and preserve explicit empty-string cases.- Target derivation reads
git remote get-url origin, but the existinggit push originbehavior followsremote.origin.pushurl. Usegit remote get-url --push originand define a fail-closed policy for multiple push URLs; otherwise this PR can redirect the protected push away from the repository the release configuration would normally use. sshTargetFromOrigin()parses HTTPS with a permissive regex. Userinfo, ports, query strings, and fragments are not validated. For example, an HTTPS URL containing userinfo is transformed into a malformed SSH target, and a failedrunLoud()prints the full target throughcommand.join(" "), which can disclose embedded credentials. Parse the URL structurally, reject userinfo/query/fragment, handle supported ports with a validssh://target, and make push-failure diagnostics remote-safe.
There is also a repository-policy mismatch that must be documented or narrowed before merge. The current main and preview rulesets authorize the DeployKey actor category with actor_id: null, not deploy key ID 160903473 specifically. Today only the named release key is writable, but adding another writable deploy key would inherit the bypass. The PR description/comments should not claim that this is cryptographically limited to one credential or that deleting one key necessarily closes the category-wide carve-out. Prefer a specifically identified GitHub App actor if exact credential scoping is required; otherwise document and enforce the invariant that no additional writable deploy keys are permitted.
Please keep this unmerged until these boundaries have focused negative-path coverage and the corrected exact head has full CI plus explicit security review.
…ndings An independent opus-high audit found three real defects in the deploy-key work, one of them release-blocking and demonstrated. 1. The release aborted at its own preflight. OCX_RELEASE_SSH_KEY must be exported for the push to work, and the preflight runs the test suite as a child that inherits it. The harness only ADDED the variable per scenario and never removed an inherited one, so the "no key configured" case ran with a key and failed -- reproduced: 16 pass / 1 fail with the key exported. The next release would have died at preflight, the same class of failure as v2.29.0 one stage earlier. Scrub both variables from the inherited environment the way PATH already is. 2. A credential in the origin URL was transplanted into the SSH target. The host capture accepted userinfo, so https://user:TOKEN@host/o/r.git became part of the push target -- and runLoud prints the failing command, putting the token on the terminal and in the release log. That violates the no-secret-logging rule in scripts/AGENTS.md, which privacy:scan cannot catch because it scans source rather than runtime output. Refuse a credential-bearing remote instead of building a target from it. 3. OCX_RELEASE_SSH_REPO was unvalidated and outranked origin unconditionally, so a stale exported value from a fork session could silently retarget a production release. Validate the remote shape and echo the resolved target before pushing, so the destination is visible rather than inferred. Adds four regression tests: credential-bearing origin, malformed override, ssh-origin passthrough, and the no-target abort. The credential case was driven red against the permissive host capture. 21 pass / 0 fail, and the suite now passes with the deploy-key variables exported -- the environment a real release actually runs in.

Reject credential-bearing SSH targets.

The earlier single-clock fix was necessary but not sufficient. It made ONE rebuild self-consistent, and this test compares TWO separate rebuilds -- so each call still legitimately reads its own millisecond, and the raw JSON comparison still failed whenever the two calls straddled a boundary. It failed again on the macOS leg after that fix landed. The assertion was testing the scheduler, not the contract. The contract is that heartbeats must not change what the continuation sends; timestamps are not part of that claim. Strip them and compare the content. The single-clock invariant stays pinned by the test directly below this one, so the source guarantee is not lost.
