ci: build the unit-test target on Xcode 27 and baseline approved historical secret findings

- config/test-base.xcconfig (unit-tests target only): MACOSX_DEPLOYMENT_TARGET 10.13 -> 12.0, the lowest Xcode 27.2 supports. The shipping app keeps 10.13 in config/base.xcconfig (also read by scripts/update_appcast.sh).
- Same file: deprecation warnings (APIs deprecated in macOS 11/12 and used by the 10.13 app code) are downgraded for the test build only, via -warnings-as-errors followed by -Wwarning DeprecatedDeclaration; every other warning stays an error.
- .gitleaksignore: the six exact historical fingerprints from the central scan, no patterns.

Guards A (Test scheme), B (LicenseManager depaywall markers) and C (conflict markers) are unchanged.

+- [x] **Auto-update** — `DOMAIN = koftwentytwo.github.io/CommandTabFree`, `SUEnableAutomaticChecks = true`, in-tree `appcast.xml` removed + gitignored. GitHub Pages serves the gh-pages feed; v100.2.0 ships auto-updating.
+- [x] **Homebrew cask** — bumped to v100.2.0 + quarantine-strip postflight dropped (`KofTwentyTwo/homebrew-tap`).
+- [x] **Release-gate decouple** — sign/notarize/release apparatus gated on a `will-release` signal (empty `VERSION.txt` ⇒ no release); non-release pushes build+test without cutting a release or needing `[skip ci]`.
+- [x] genstrings gate fixed (`d1e1b296`); ad-hoc-until-cert build (`6070f0cb`); `.fork-sync-state` reset to `v11.3.0` + release tail no longer clobbers it; 3 sync labels created.
 
-## Auto-update (deferred by choice — appcast already publishes to gh-pages)
-- [ ] **Real `DOMAIN`** — replace `fork.invalid` in `config/local.xcconfig` with the fork host (kof22.com).
-- [ ] Serve the gh-pages `appcast.xml` at `https://<DOMAIN>/appcast.xml` (CNAME the gh-pages site).
-- [ ] `git rm` the in-tree `appcast.xml` skeleton + gitignore it (feed is published out-of-tree to gh-pages); flip `SUEnableAutomaticChecks` back on (PLAN §3.2).
-
-## Homebrew cask (now that builds are notarized)
-- [ ] Drop the quarantine-strip postflight (`xattr`) from `KofTwentyTwo/homebrew-tap` `Casks/commandtabfree.rb` — no longer needed for a notarized app.
-- [ ] Bump the cask to v100.1.0.
-
-## Upstream-sync automation
-- [x] `.fork-sync-state` reset to `v11.3.0`; release tail no longer clobbers the cursor with the fork tag (`ci_cd.yml`).
-- [ ] **Re-wire the cursor advance** into the upstream-sync merge flow so it records the synced **UPSTREAM** tag (not the fork release tag) — `upstream_sync.yml` (PLAN §4.2).
+## Remaining — Upstream-sync automation (owner-gated)
 - [ ] **`SYNC_BOT_TOKEN`** — GitHub App installation token (or fork PAT with contents + pull-requests write). Default `GITHUB_TOKEN` does NOT re-trigger PR checks, so guards never run on the sync PR.
 - [ ] **External cron** — hit `repository_dispatch` (type `upstream-sync`) from an external scheduler (immune to GitHub's 60-day in-repo `schedule:` auto-disable).
-- [x] Sync PR labels `sync` / `conflict` / `chokepoint-refresh` created.
+- [ ] **Re-wire the `.fork-sync-state` cursor advance** into the upstream-sync merge flow so it records the synced **UPSTREAM** tag (not the fork release tag) — `upstream_sync.yml` (PLAN §4.2).
 
-## Bootstrap acceptance tests (after the above)
+## Optional
+- [ ] kof22.com custom domain for the appcast (one DNS CNAME → `koftwentytwo.github.io`; GitHub redirects the github.io URL, so existing builds keep updating).
+
+## Bootstrap acceptance tests (after upstream-sync is wired)
 - [ ] Sync PR through the bot shows guard checks running.
 - [ ] A deliberately-relocked branch goes RED on `guard.yml`.
-- [ ] Fork build N→N+1 auto-updates via Sparkle (needs DOMAIN/appcast live).
-
-## Done earlier this session (2026-06-16)
-- [x] genstrings consistency gate fixed — regenerated base `Localizable.strings` from source (`d1e1b296`).
-- [x] `build_app.sh` builds ad-hoc until cert provisioned; was failing on upstream's Developer ID (`6070f0cb`). Push CI green (run `27634828800`).
+- [x] Fork build N→N+1 auto-updates via Sparkle — infra live (feed served + v100.2.0 auto-update-enabled); end-to-end N→N+1 confirmed on the next release.
