Replace fixed Linux Hopper release pins with current vendor feed metadata,
complete detached-PGP package verification under the stable publisher primary
key, and authenticated package evidence for offline admission. Share parsed
publisher facts across approved setup, doctor and the pre-execution guard.
Preserve existing ownership, cancellation, private-display and cleanup rules.
Fixes#3577
Normalize empty XDG settings, preserve backups during approved cache repair,
and retain publisher cleanup through cancellation and shutdown. Exercise cold
offline verification without reusing process-local proof state. Serialize
approved cache publication across processes, restore old evidence on failure,
and share the existing lease owner from process without changing its identities.
Validation: 438 focused tests (six platform-related skips), full static/documentation checks, real Ubuntu
24.04 official Hopper 6.6.0 setup/CLI/MCP, offline ordinary-user admission,
launcher mutation rejection, and cold/warm verification measurements. Official
RPM metadata mismatch is tracked separately in #3578 and fails closed.
BREAKING CHANGE: Older Linux Hopper builds admitted by the fixed allowlist
now require retained publisher-signed package evidence or an approved update
to the current public demo. Update explicit HOPPER_LAUNCHER_PATH values when
migrating; the live feed exposes only its current release.

Verify the native helper's sealed identifier and pinned Apple signing team in BridgeLauncher, then carry that provenance to HopperClient. Only a verified native helper's complete not-found exit confirms no document handoff, allowing runtime and target-lease cleanup and retry; wrappers retain unknown document state.
Share publisher identity with setup through the domain contract. Correct fixture teardown ordering and parameterized MCP coverage. Validation: 54 focused tests passed across boundary, CLI, MCP acceptance, diagnostics and installer coverage (one Linux-only case skipped); check:fast passed. Real codesign verification accepted the installed official Hopper helper; Spotlight failures and bridge recovery used process fixtures.
The macOS installer accepted any bundle that passed `codesign --verify`
and whose `Info.plist` said `com.cryptic-apps.hopper-web-4`. An ad-hoc
signed bundle with that identifier satisfies both, so a substituted DMG
could be copied to ~/Applications and launched.
Verify a pinned code requirement instead, covering the sealed bundle
identifier and the signing team together, and report a distinct
`publisher_verification_failed` code so a vendor key change is not
confused with a corrupt package.
Track attempted writes, preserve original content and modes from one regular-file observation, and continue rollback after individual failures. Return tagged failure details and retained backup paths through setup.
Validation: setup filesystem and recovery tests, combined compile/typecheck/lint/format/metadata/architecture checks. Filesystem fault injection covers backup, ambiguous publication, and rollback failures.
