(src/serviceModules/FileSystemAdapters/pathAliasGuard.ts)
- Require every existing, unindexed path component to use a name listed by its parent directory.
- Accept case-only and Unicode-normalisation differences while caching positive directory listings briefly.
(src/serviceModules/FileSystemAdapters/ObsidianStorageAdapter.ts, src/serviceModules/FileSystemAdapters/ObsidianVaultAdapter.ts)
- Apply the alias boundary before text, binary, append, directory, removal, create, modify, rename, delete, and trash operations.
- Check both the source and destination of vault renames before calling the host API.
(src/serviceModules/FileSystemAdapters/pathAliasGuard.unit.spec.ts)
- Cover directory and file aliases across every mutating adapter route with synthetic host behaviour.
- Exercise real host filesystem aliases where the platform exposes them, including new files and directories below an aliased folder.
- Preserve listed names, case-only differences, indexed paths, and new-file behaviour.
(src/serviceModules/FileSystemAdapters/ObsidianStorageAdapter.unit.spec.ts, src/serviceModules/FileSystemAdapters/ObsidianVaultAdapter.unit.spec.ts)
- Extend existing adapter fixtures with the vault-index contract used by the guard.
Obsidian's mobile storage layer forwards mtime/ctime to Capacitor's
Filesystem.setTimes, whose native binding casts the value to a Java Long.
A non-integer (float) timestamp makes that cast throw (ClassCastException:
Double cannot be cast to Long), which crashes the app on launch as soon as
such a document is replicated in.
Float timestamps can reach the database from any client that stores
fs.Stats.mtimeMs without flooring. Coerce mtime/ctime to integer ms at the
Obsidian vault and storage adapter write boundary, so a float already
present in the mesh can't crash the app regardless of where it came from.
The truly central choke point is dbToStorage in livesync-commonlib; a
matching guard there would cover the CLI and webapp too. This change
protects the platform that actually crashes.
