It extends the Beta domain-operation inventory with +local file editing. It does not change IPC envelope version 1, session +ownership, worktree deletion, or Linux/macOS support. In particular, the +relative file identifiers below are a scoped extension of ADR 0002; arbitrary +absolute filesystem paths remain invalid domain-operation inputs. + +## Context + +The daemon currently exposes registered project, session and worktree IDs, +but no file-listing or editor-save operation. S1 needs a real file tree and +editor on the canvas. S3 needs a reusable safe reader for explicitly selected +rule/skill files; a second filesystem service would create conflicting access +and overwrite policies. + +The user requested files/editor after worktree integration, including real +disk effects and restart behavior. A generic Tauri filesystem command, shell +command, or Rust type without a daemon handler would not fulfill that request. +Linux filenames are byte sequences and need not be UTF-8. A check using +`canonicalize` followed by an unrelated pathname `open` can follow a replaced +symlink. Atomic replacement prevents partial files, but portable Unix rename +does not provide compare-and-swap against an external editor's last write. + +## Decision + +### Ownership and initial scope + +Implement `file.list`, `file.read` and `file.write` in the daemon, backed by a +single internal `LocalFileService`. Core owns pure validated values and DTOs; +it performs no filesystem, hashing of open files, clock, or process I/O. +Storage resolves existing metadata IDs and remains the only SQLite owner. +No new table or migration is required for these three operations. + +Add each method to Rust wire, JSON catalog and TypeScript mirrors only with +its functional handler. The desktop continues to use `daemon_invoke`; there +is no `file_read` or other domain-specific Tauri command. Operations run in +bounded blocking tasks rather than on the asynchronous socket reader. + +`file.write` replaces an existing regular text file. It never creates a +missing file or parent directory, renames a user file, or deletes one. Those +remain required future file-management increments, tentatively under +`file.create`, `file.rename`, and `file.prepare_delete`/`file.delete`; they +are not advertised or implemented as stubs now. Creation will require +exclusive creation, rename a no-clobber/state policy, and deletion a reviewed +state-bound target. This sequencing does not remove M29's remaining scope. + +### Target and byte-exact path contracts + +Every request carries one registered target: + +```text +FileTarget = { kind: "project", projectId: UUIDv7 } + | { kind: "session", sessionId: UUIDv7 } + | { kind: "worktree", worktreeId: UUIDv7 } +FilePath = canonical padded base64 of repository-independent Unix path bytes +FileRevision = "v1:" + 64 lowercase hexadecimal SHA-256 characters +``` + +`FileTarget` has the same tagged representation as the existing Git target, +but file semantics belong to this service. A project resolves to its +registered selected directory, a session to its persisted cwd, and a worktree +to its managed root. The service must not expand a project subdirectory to +the repository root. Worktree-backed targets require an active association; +creating/orphaned/removal-pending targets are not writable. Reads may explain +recovery state, but must not substitute another directory silently. + +Roots are derived from daemon metadata and validated on every operation; +clients do not echo a root path back as authority. Root opens must reject a +persisted canonical root that now resolves elsewhere. Managed worktree +identity checks reuse the runtime worktree validation before granting access. + +`pathBase64` is limited to 4096 decoded bytes. Empty bytes represent the root +only for `file.list`. Nonempty paths are relative `/`-separated components; +reject leading/trailing `/`, empty components, NUL, `.` and `..`. Names with +spaces, Unicode, non-UTF-8 bytes, leading `-`, literal backslashes or colons +remain valid Unix names. There is no Windows-path normalization, Unicode +normalization, case folding or Git pathspec interpretation. The existing +`GitRelativePath` is deliberately not reused. + +Responses return `pathBase64` as the exact identifier and `displayName` for +presentation. Escape control/undecodable bytes in display text; never rebuild +an operation path from that text. Raw names never become HTML or command +arguments. Non-UTF-8 names are listable and can identify an editable UTF-8 +file where the underlying filesystem permits such names. APFS can reject +invalid UTF-8 filenames with EILSEQ before the service is called; Linux socket +tests exercise those names and pure contract tests cover their wire identity +on both platforms. + +### Public operations + +All payloads use camelCase, reject unknown fields and keep existing versioned +response envelopes. Optional fields are omitted when absent. + +| Method | Request | Successful response | +| --- | --- | --- | +| `file.list` | `{ target, pathBase64, limit?, afterNameBase64? }` | `{ entries: FileEntry[], nextAfterNameBase64?, observedAtMs }` | +| `file.read` | `{ target, pathBase64 }` | `{ pathBase64, text, revision, sizeBytes, modifiedAtMs?, observedAtMs }` | +| `file.write` | `{ target, pathBase64, text, expectedRevision }` | `{ pathBase64, revision, sizeBytes, modifiedAtMs?, writtenAtMs }` | + +`FileEntry` is `{ pathBase64, displayName, kind, sizeBytes?, modifiedAtMs? }`. +Kind is `file | directory | symlink | other`; it describes observed type, not +an access grant. Symlinks are visible but not traversed or edited. `other` +includes devices, sockets and FIFOs and cannot be opened through this API. + +List one directory, not a recursive tree. Default page size is 100, maximum +200. Order by raw name bytes; `afterNameBase64` is a validated single filename +and is an exclusive lexicographic cursor. Bound enumeration to 10,000 entries +and the encoded response to 512 KiB, returning a continuation cursor before +exceeding the response budget. A directory exceeding the enumeration limit +returns `file_listing_too_large`, never a success implying an empty tree. +Pages are observations, not a transaction snapshot: concurrent changes before +the cursor may require refresh. Search and persistent indexing are separate +increments. + +Read/write text is limited to **128 KiB of UTF-8 bytes**, including any BOM. +This bound allows worst-case JSON escaping inside the existing 1 MiB frame +with room for the envelope. Preserve bytes represented by the text exactly, +including CRLF, final newline and BOM; do not normalize automatically. +The service reads at most the limit plus one byte and rejects oversized +files, invalid UTF-8 or NUL-containing content. Binary/media previews need a +separate bounded byte/asset operation; this text slice does not claim them. +`file.list` can still show those files. The UI keeps its unsaved buffer after +every error. + +All timestamp fields are Unix epoch milliseconds. File modification time is +optional if it cannot be represented; absence is not zero. Revision checks +use higher-resolution metadata internally and never depend on epoch-ms alone. + +### Descriptor-relative filesystem access + +Use safe APIs from the existing direct daemon dependency `rustix 1.1.4` with +feature `fs`. Its local source provides `openat`, `statat`, `fstat`, `renameat`, +`unlinkat`, directory iteration and `fsync`. Traversal and publication introduce no project `unsafe` block, shell +command, external file utility or platform-specific path syntax. Darwin ACL +inspection has the narrowly isolated exception defined below. `renameat` is the portable directory-relative replacement operation. +[rustix reference](https://docs.rs/rustix/1.1.4/rustix/fs/fn.renameat.html) + +Open the validated root as a directory descriptor, then walk each path +component relative to its already-open parent with +`RDONLY | DIRECTORY | NOFOLLOW | CLOEXEC`. Open a leaf with +`RDONLY | NOFOLLOW | NONBLOCK | CLOEXEC`, then `fstat` that descriptor and +require a regular file before reading. `NONBLOCK` prevents a FIFO substituted +at the leaf from hanging the daemon. Use no-follow stat for listing entries; +never open an `other` entry as if it were ordinary text. + +Keep the parent descriptor through validation, temporary-file creation and +rename. Reopening an absolute concatenated pathname after validation is not +an acceptable fallback. Revalidate root/parent device+inode identity before +publication; if metadata registration or directory identity changed, abort +with `file_target_changed` and discard only the service-owned temporary file. +For managed worktrees, hold a short operation lease against worktree removal +for the final write transaction. File reads need no process lifecycle lock. +File I/O must not delay stop of an unrelated session behind enumeration. + +Descriptor-relative traversal prevents symlink substitution from redirecting +access. It does not promise that a directory descriptor's inode remains at +the same pathname if another same-user process renames that directory. The +service acts on the opened object and detects observed namespace changes; +it is not a security sandbox against another process with the same Unix UID. + +### Revision checks and atomic save + +Compute revision in the daemon over file bytes plus identity and change +metadata: device, inode, size, high-resolution mtime/ctime, link count and +permission mode. Encode fields canonically with a version prefix and hash +with SHA-256; the resulting `FileRevision` remains opaque to clients. Make +`sha2 0.10.9`, already resolved in the workspace lockfile, a direct daemon +dependency if used. The revision is content/identity-based, not a database +counter or process-local token, so unchanged files can be checked after a +daemon restart. It is not an authorization credential. + +For read, compare descriptor metadata before and after the bounded read; +return `file_conflict` if a concurrent change was observed. For write: + +1. Acquire a service mutation lock keyed by parent device/inode and raw leaf + name. It must serialize overlapping requests even when target IDs differ. +2. Open/inspect the current leaf by descriptor, reject nonregular files and + multiple hard links, read its bounded bytes, and require the caller's + `expectedRevision` to match the observed revision. +3. Create a unique sibling temporary file with `CREATE | EXCL | NOFOLLOW`, + initially mode 0600. Write the complete new text, apply the supported + permission metadata, flush and `fsync` the temporary descriptor. +4. Reopen/reinspect the current leaf through the same parent, verify identity + and revision again and revalidate the target/parent. On conflict leave the + original untouched and remove only that operation's temporary file. +5. Atomically `renameat` the temporary sibling onto the existing name, then + `fsync` the parent directory. Return a revision for the published inode. + +Ownership/group and ordinary permission bits must be preserved when saving; +if this cannot be done without elevated access, reject the write. The first +slice is not a full metadata-preserving file copier: ACLs, extended attributes, +resource forks and platform flags need explicit preservation or a documented +unsupported result before accepting such a save. They must not be silently +advertised as preserved. Hard-linked files return `file_metadata_unsupported` +because replace would otherwise break the link relationship. + +The initial macOS implementation preserves one explicitly supported extended +attribute, `com.apple.provenance`. Real files created on the validation host +receive this attribute automatically, including the service's temporary files. +Read its bounded value through the pinned descriptors, copy it when needed, +and verify that the source and destination attribute sets and bytes agree +before publication. If the source has no such attribute and the destination +does, reject the save unless exact absence can be established; do not assume +that a successful removal call proves absence. Reject every other extended +attribute, oversized value or inspection/copy mismatch. This is a narrow +preservation exception, not permission to silently discard unknown metadata. + +The lock guarantees revision ordering among daemon writers. External editors +do not honor it. The final comparison followed by POSIX `renameat` leaves a +small external-write race: it is **optimistic conflict detection**, not a +filesystem compare-and-swap or a guarantee of zero lost updates against an +uncooperative writer. This limitation must remain in editor/save documentation +and tests must not claim to prove its absence. A later stronger design may +add recoverable versions or platform primitives under another ADR. + +Failure before rename does not alter the destination. Failure after rename +is materially different: return `file_durability_uncertain` with +`writeApplied: true` and the observed revision when possible, instructing the +client to re-read before retrying. Do not pretend rollback occurred or send a +second implicit write. A daemon crash can leave a uniquely named temporary +file; startup must not sweep unknown files from project directories. + +### Narrow Darwin ACL metadata boundary + +The current safe `rustix` interface does not provide Darwin ACL inspection +through a file descriptor. The safe public exacl API takes a pathname, which +would lose the pinned-object guarantee; `/dev/fd` is not assumed equivalent. +A normal macOS text file must remain editable while a file with an extended +ACL must not lose that ACL during atomic replacement. + +Add `crates/file-metadata` solely for the safe public function +`has_extended_acl(fd: impl AsFd) -> io::Result`. Its private Darwin +module contains the minimal audited bindings to `acl_get_fd_np`, +`acl_get_entry` and `acl_free`. Constants and signatures are verified against +the installed Apple SDK. The borrowed descriptor is never closed, returned +ACL storage is owned by an RAII guard, errors preserve errno, and callers +never receive raw pointers. No subprocess or path reopening is permitted in +this service. Linux continues to inspect ACL/xattrs through safe rustix APIs. + +This crate explicitly denies unsafe code except within that private module, +and denies unsafe operations within unsafe functions unless individually +marked. It is the sole exception to inheriting the workspace's unsafe-code +forbid lint; workspace/core/daemon/session policy remains unchanged. All +other lints retain the workspace's strictness.
