fix(install): recover native ownership after macOS device renumbering - #304
Conversation
Stored directory identities are st_dev:st_ino. macOS assigns a volume's device number at mount time, so after a reboot the same native generation directory can read 16777233:400099505 where the ledger recorded 16777234:400099505. Every Commit, snapshot read, upgrade, purge and rollback then refused with "native directory inode changed" and the update could never complete. Compare recorded identities through PersistedIdentityMatches: an exact match as before, or the same inode on the same device as its freshly opened parent, which still refuses a mount point substituted at the path. The native directory check, the rename source check and the setup state check use it. Commit records the current identities in the next ledger, so the ledger converges and older writers sharing the control root accept it again. Windows identities use the volume serial and stay exact. Refs #301
A transaction interrupted before a reboot keeps the parent anchors and purge entries it recorded, each with the old device number. Recovery compares them exactly, so after the volume is renumbered it refused with "managed destination parent substituted" and the pending journal blocked every later install. When a pending journal is loaded, derive a device mapping from its recorded parent chains. Each chain must name the same paths and inodes as now, and every recorded device must map to exactly one current device and back. Only then are the journal's anchors and purge entries re-keyed in memory. A chain that now crosses a different mount, or any changed inode, leaves the journal as recorded for the existing checks to refuse. Refs #301
Refreshing the retired record made qualifyRetirement see a changed live generation, so retiring a legacy candidate on a renumbered volume left a journal that neither recovery nor rollback could clear. Retirement now keeps its record unchanged and the next commit converges it. Refresh also returned any error from opening an older generation, so a damaged generation that is neither live nor previous failed every commit. Such a generation now keeps its recorded identity. Adds tests for both, for a replaced older generation, and for the mount point rule against a real nested mount. Refs #301
Keep unverified native ownership unchanged for bounded policy revocation. Validate device correspondence for deleted retirement inventory across multiple boots and cover interrupted recovery. Refs #301

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winPrint the durable native path even when refresh finds no changed files.
When
--refresh --print-native-pathis invoked with no changed files and no--entryflag, the function returns at line 120 before reaching the print branch at lines 298-303. This produces no output, contradicting the flag's contract to print the committed durable native generation path.The test
TestInstallRuntimePrintNativePathdoes not cover this case: it tests successful commits with--print-native-path, but not the no-op refresh scenario where no files changed. The--refreshtests in other files do not combine--refreshwith--print-native-path.To fix this, load the existing ledger on the no-op path and print its native path:

Validate active native bytes before replaying an enabling policy transaction.
refreshLedgerIdentities checks directory identity only. It accepts unchanged inodes after in-place content changes and skips missing paths. ledgerMatchesJournal compares normalized ledger metadata but does not hash the native tree. validateNative(nil) performs no check for policy-only transactions.
For non-revocation replay, when tx.After.Native exists, require its active directory and compare its tree fingerprint with tx.After.Native.SHA256 before publishing policy. Keep the bounded-revocation exception. A transaction with no native record does not need this directory check.
The same-identity mutation or disappearance was already possible in the base revision. This PR also makes the Darwin identity-renumbering case recoverable without adding content validation.

macOS persisted native ownership now survives device renumbering across reboots while retaining strict inode, parent topology, content fingerprint and in-process checks. Linux and Windows continue using exact identities.
