release: v1.3.2 — signed and notarized macOS builds

[pacnpal]

Why

The Developer ID signing + notarization pipeline landed in #23, with follow-up fixes in #24 and #25. All of that is on main — but no release ships it. release.yml only publishes assets on a pushed v* tag, and the newest tag, v1.3.1, was cut 2026-05-11, months before the signing work. Every macOS zip a user can download today is still the old ad-hoc-signed build that Gatekeeper blocks.

This PR is the release prep. Merging it and pushing v1.3.2 is what actually puts a signed, notarized macOS build in front of users, and fires the project-update dispatch that refreshes POSTBEEP.NET.

Signing is already verified working

The 2026-08-20 workflow_dispatch smoke-test (run 32396109633) ran on 71446a5 and succeeded end-to-end:

Job	Import cert	Codesign	Notarize + staple
macos-arm64	✅	✅	✅
macos-x86_64	✅	✅	✅
macos-universal2	✅	✅	✅

Publish release assets was skipped, as designed — a manual dispatch never publishes. Only a tag push does.

Changes

Version bump to 1.3.2. pyproject.toml had been left at 1.2.6 through both the v1.3.0 and v1.3.1 tags. This isn't cosmetic: __version__ is read from installed package metadata and stamped into the boot menu of every disc the tool builds (MENU TITLE FloppyBootCD vX.Y.Z), so discs burned with v1.3.1 identify themselves as v1.2.6. It also surfaces in --version and the About dialog. Artifact filenames come from the tag and were always correct.

The release gate now fails closed. Caught in review, and a real bug. The signing scripts deliberately exit 0 when their secrets are absent, and Locate signing tooling only warned when the tooling was missing — so a tag cut with a lapsed certificate would have published a Gatekeeper-blocked bundle under docs promising the opposite. A single MACOS_SIGNING_REQUIRED contract, set at the workflow level for pushed v* tags only, makes all three scripts and both Locate signing tooling steps hard-fail instead. Fork PRs, dispatch smoke-tests, and secret-less repos keep the graceful degradation untouched. A release now either carries a real signature and a stapled ticket, or it doesn't happen.

macOS install docs rewritten. README, the Pages site (docs/index.html), and .postbeep/docs.md all told every macOS user to run xattr -dr com.apple.quarantine. From v1.3.2 that step is unnecessary. .postbeep/docs.md was the furthest behind — it described the app as flatly "unsigned", and it's the copy rendered on POSTBEEP.NET's project docs page. Each now leads with the plain unzip-and-open path plus the spctl verification command, with the xattr workaround moved out of the happy path and scoped to v1.3.1 and older. .github/signing/README.md documents the new fail-closed contract.

Editing .postbeep/docs.md also triggers notify-postbeep.yml on merge, so the hub picks up the corrected docs page without waiting for the release.

Testing

242 passed across tests/core and tests/test_cli.py, including test_bootloader.py's assertion that the boot-menu title tracks __version__. floppybootcd.__version__ resolves to 1.3.2. Each signing gate was exercised both directions locally — clean no-op and exit=0 without MACOS_SIGNING_REQUIRED, hard failure and exit=1 with it — as was the Locate signing tooling branch. release.yml parses as valid YAML; all four signing scripts pass bash -n. The tests/ui suite could not run in this container (no libEGL.so.1); it is unaffected by these changes and CI covers it.

After merge

Push v1.3.2 to trigger the release build. That publishes the signed artifacts and, as the release job's last step, dispatches the POSTBEEP.NET rebuild. pacnpal/POSTBEEPNET#31 bumps the hub's offline fixture pin to match.

📝 Walkthrough

Summary by CodeRabbit

• New Features

  • macOS releases v1.3.2 and later are code-signed and notarized, allowing them to open through Gatekeeper without manually removing quarantine settings.
  • Added optional instructions for verifying macOS app signatures.

• Bug Fixes

  • Clarified installation steps for older unsigned macOS releases, which still require quarantine removal.

• Documentation

  • Updated the README, website, and installation guide with the revised macOS setup instructions.

Walkthrough

The project version changes to 1.3.2. macOS installation instructions now describe signed and notarized builds, provide optional spctl verification, and limit quarantine removal to v1.3.1 and older builds.

Changes

macOS release installation

Layer / File(s)	Summary
Release version and installation behavior pyproject.toml, docs/index.html	The project version changes to 1.3.2. The macOS install command no longer removes quarantine for every build.
Installation guidance alignment .postbeep/docs.md, README.md	The documentation states that v1.3.2 and later builds are signed and notarized. It retains the xattr workaround for v1.3.1 and older builds and adds spctl verification guidance.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 75f64

The release documentation promises that v1.3.2 macOS builds are signed and notarized, but the release process can still publish an ad-hoc-signed build if signing credentials are unavailable, creating a concrete risk that users receive artifacts that do not match the documented install experience. The verification command and legacy workaround instructions also need small corrections, so merge should wait for these issues to be fixed or explicitly accepted.

All four review findings verified and fixed in 0b5cd88.

The fail-open release gate (flagged by both bots, on README.md#L145 and docs/index.html#L447) was a real bug, and the more interesting of the two suggested remedies was the right one. Confirmed by reading the scripts: macos-import-cert.sh and macos-notarize.sh both exit 0 when their secrets are absent, and Locate signing tooling only emits a ::warning:: when the tooling is missing — while every signing step below is gated on steps.signing.outputs.dir != ''. So a tag cut with a lapsed certificate or a missing notary key would have published a Gatekeeper-blocked bundle under docs promising the opposite.

Rather than water the docs down to match a weak guarantee, I made the guarantee strong. New MACOS_SIGNING_REQUIRED contract, set once at the workflow level and only for pushed v* tags:

MACOS_SIGNING_REQUIRED: ${{ github.event_name == 'push' && startsWith(github.ref, 'refs/tags/v') && '1' || '' }}

All three signing scripts turn their clean no-op into a hard failure with a message naming the missing secret, and missing tooling is now fatal on a tag build in both the matrix job and build-macos-universal2. Fork PRs, workflow_dispatch smoke-tests, and secret-less repos keep the graceful degradation exactly as before — that path is what makes fork PRs buildable and I didn't want to lose it.

Verified both directions locally for each script and for the locate step: no-op and exit=0 without the flag, hard failure and exit=1 with it.

A release now either carries a real Developer ID signature and a stapled ticket, or it doesn't happen. That's what makes the docs' claim unconditional rather than best-effort, so the three doc sites keep their plain wording.

The two smaller ones were both mine, introduced by this PR:

• docs/index.html — the spctl example checked the relative floppybootcd.app after the block had already moved it to /Applications/, so following the steps in order made the check fail. Now points at the installed path.
• README.md — the legacy xattr line sat inside the same copy-pasteable fenced block as the current-release steps, so a v1.3.2 user working top to bottom would still strip quarantine. Moved into a collapsed "Downloading v1.3.1 or older?" section, well away from the happy path.

.github/signing/README.md documents the new contract for whoever rotates these secrets next.

242 tests pass. tests/ui can't run in this container (no libEGL.so.1) and is untouched by these changes.
