fix(swift): repair release build, signing, and draft paths

[steipete]

What Problem This Solves

The first production Swift CLI release uncovered several broken paths in the reusable workflow:

• Linux container steps ran Bash-only syntax under /bin/sh.
• Hosted macOS rejected direct PKCS#12 import.
• PKCS#12 compatibility handling differed between OpenSSL 3 and LibreSSL, and Bash 3 rejected an empty-array expansion under set -u.
• The ephemeral signing keychain was not selected in the user search list, so codesign could not access an imported identity.
• The draft job invoked gh release create --verify-tag without a Git checkout.
• The release-by-tag REST endpoint returned 404 for a newly created draft.

Why This Change Was Made

Repair each failure at the shared workflow boundary without changing caller inputs, permissions, signing identity, artifact names, verification gates, publication binding, or Homebrew handoff:

• select Bash for the Swift Linux container job;
• extract PKCS#12 certificate/key material with capability-driven OpenSSL compatibility;
• import the certificate and private key separately;
• select the ephemeral keychain before signing;
• check out the already validated frozen tag before draft creation;
• resolve draft IDs through draft-aware gh release view.

Contract tests cover every repaired invariant.

Evidence

• Full scripts/validate-workflows.sh suite passes, including actionlint, YAML parsing, tag-freeze, signing, draft-binding, verifier, and Homebrew adversarial scenarios.
• Real swift:6.3.3-noble linux/amd64 proof resolves dependencies, patches them, builds imsg-linux-x86_64.tar.gz, runs the ELF binary, and reports 0.14.0.
• Real Developer ID proof extracts the stored credential, imports certificate/key into an ephemeral keychain, signs a Mach-O probe, and passes strict verification.
• Production release run https://github.com/openclaw/imsg/actions/runs/31434537833 passed macOS/Linux builds, signing, notarization, arm64/Intel verification, publication, and Homebrew handoff.
• Published release: https://github.com/openclaw/imsg/releases/tag/v0.14.0

ClawSweeper review

What this changes

This PR repairs the reusable Swift release workflow’s Linux shell, macOS signing import, and draft-release creation paths, with matching contract assertions.

Merge readiness

⚠️ Needs maintainer review before merge - 2 items remain

Keep open: the signing repair still replaces the macOS user keychain search list without restoring it after deleting the ephemeral keychain.

How this fits together

The reusable Swift release workflow builds tagged macOS and Linux archives, imports a signing identity to sign and notarize macOS assets, then creates and verifies a draft release. It consumes caller release inputs and secrets and produces signed artifacts for publication and Homebrew handoff.

Before merge

• Restore the prior user keychain search list (P2) - security list-keychains -d user -s replaces the runner’s user search list, but the final cleanup only deletes $KEYCHAIN. Save the prior list and restore it in an always-run step; otherwise later signing work can retain a reference to the deleted ephemeral keychain.
• Resolve merge risk (P1) - Merging may leave a macOS runner’s user keychain search list pointing at a deleted temporary keychain, disrupting later signing work in that runner context.

• [P2] Restore the prior user keychain search list — .github/workflows/release-swift-cli.yml:543

Merge-risk options

Maintainer options:

1. Restore the user keychain list (recommended)
   Save the existing user search list and restore it in always-run cleanup so this signing repair does not leave the runner with only a deleted ephemeral keychain.

Technical review

Best possible solution:

Preserve the previous user keychain search list before selecting the ephemeral keychain and restore it in always-run cleanup, with a focused workflow contract assertion.

Do we have a high-confidence way to reproduce the issue?

Yes — source inspection shows that the workflow replaces the user keychain search list and its cleanup deletes the replacement without restoring the prior list.

Is this the best way to solve the issue?

No — the import repair is appropriate, but it must restore the prior runner keychain state in guaranteed cleanup to be upgrade-safe.

Labels

Label justifications:

• P1: This shared release path can block real Swift releases until its runner-state cleanup is safe.
• merge-risk: 🚨 availability: A stale user keychain search list can disrupt subsequent macOS signing work.
• merge-risk: 🚨 security-boundary: The patch changes lifecycle and selection of production signing credentials and keychains.
• rating: 🦐 gold shrimp: Overall readiness is 🦐 gold shrimp; proof is 🦞 diamond lobster and patch quality is 🦐 gold shrimp.
• proof: sufficient: Contributor real behavior proof is sufficient. The PR body provides a linked completed production release run showing the repaired macOS and Linux release path through publication and handoff.

Real after-fix container proof on a6e45450a50a5be4f2e86fba0f138275e53d0055:

• source: immutable openclaw/imsg tag v0.14.0 at 7e8f89ab6efc120129605dc23d8cb1cc2d7e8855

This exercises the affected dependency-preparation and archive-build steps in the actual Swift release container, including the Bash-only pipefail and [[ ... ]] syntax that failed under /bin/sh.

Addressed the sole re-review finding in 61a1fc61b482dc1befdaa0fc172e5506958b8608 by removing the release-owned changelog line; the release context remains in the PR body and commit history for the upcoming v1.7.6 release prep.

Focused proof remains green: actionlint, the Swift CLI workflow contract test, git diff --check, and independent review all pass. Exact-head CI is rerunning now. The accepted real swift:6.3.3-noble amd64 container proof is unchanged because workflow behavior did not change in this follow-up.

[steipete]

Land-ready on 61a1fc61b482dc1befdaa0fc172e5506958b8608.

Verification:

• CI run 31411102985: validate succeeded
• full scripts/validate-workflows.sh suite passed
• real swift:6.3.3-noble linux/amd64 proof passed dependency resolution, patching, archive creation, ELF x86-64 inspection, and imsg --version = 0.14.0
• ClawSweeper marks proof sufficient
• the sole release-owned changelog finding is addressed in 61a1fc6
• final full-branch independent review is clean
• git diff --check passed

No known proof gaps remain. After merge, the fix will be released as backward-compatible v1.7.6 and the moving v1 compatibility tag will advance to that immutable release before imsg retries its frozen release.

@openclaw/openclaw-secops independent code-owner approval is the only remaining gate.

The exact head has green CI, full workflow validation, accepted real swift:6.3.3-noble amd64 behavior proof, a passing ClawSweeper review, and protected automerge armed. This backward-compatible shell fix currently blocks completion of the already-frozen imsg v0.14.0 release. I am intentionally not using the administrator bypass.

Why human review is needed:
This item has security-sensitive risk. ClawSweeper is pausing instead of making an autonomous change that could affect trust, credentials, permissions, or exposure.

What the maintainer can do as a next step:
If the maintainer accepts the current risk and wants ClawSweeper to continue merge gates, comment @clawsweeper approve. If the security-sensitive detail still needs changes, describe the safe path or push the fix, then comment @clawsweeper automerge. If the risk should not be automated, keep the PR paused for manual review or comment @clawsweeper stop.
