# TODO

This file collects follow-up work that is known but intentionally not part of the current patches. It is meant for project-level items that are too broad or too low-priority to keep as inline source TODO comments.

## Server / NCP compatibility

### Console privilege model

Current status:

- `NCP 23/200 Check Console Privileges` is implemented as a protocol-compatible status check.
- For now, console privileges are mapped to the existing supervisor-equivalence state computed for the connection.
- Callers with supervisor equivalence get success; other callers get `0xc6` (`No Console Rights`).

Follow-up:

- Add a real console-operator privilege model instead of treating console rights as identical to supervisor equivalence.
- Decide where the console privilege map should live:
  - a bindery property,
  - a server configuration option,
  - or a small explicit internal list similar to queue operator handling.
- Check how NetWare 3.x tools such as `PCONSOLE`, `SYSCON`, and console utilities expect console operators to be represented.
- Keep `NCP 23/200` as a completion-code-only endpoint; only the privilege source should change.

### Queue spool path case handling

Current status:

- Queue job paths can still be rebuilt from DOS/bindery path spelling such as `SYS:SYSTEM/EPSON.QDR`.
- On a case-sensitive Unix filesystem this can differ from the existing directory, for example `system/epson.qdr`.

Follow-up:

- Resolve queue job file paths case-insensitively in the queue connection/path resolver, or use the queue object's already-resolved Unix spool directory instead of rebuilding it from the DOS path.
- Avoid creating duplicate directories that differ only by case.

### NCP 17/4C test coverage

Current status:

- `NCP 17/4C List Relations of an Object` is implemented server-side.
- Existing DOS and Linux tools do not reliably trigger it for all useful set properties such as `GROUP_MEMBERS` and `GROUPS_I'M_IN`.

Follow-up:

- Add a small direct test utility to `mars-dosutils` / `NWTESTS` that sends `NCP 17/4C` directly.
- Suggested test cases:
  - `TESTGRP1` type `0x0002`, property `GROUP_MEMBERS`
  - `TESTGRP2` type `0x0002`, property `GROUP_MEMBERS`
  - `MARIO` type `0x0001`, property `GROUPS_I'M_IN`
  - `NOPASSUSER` type `0x0001`, property `GROUPS_I'M_IN`
  - `GUEST` type `0x0001`, property `GROUPS_I'M_IN`


### NCP endpoint SDK documentation / stub audit

Current status:

- Several legacy NCP endpoints in `src/nwconn.c` are implemented only as
  disabled stubs, explicit `0xfb` unsupported replies, or success/no-op dummies.
- The known candidates now have inline SDK-context comments so future work can
  start from the documented wire semantics instead of from guesswork.

Follow-up:

- Implement or deliberately reject remaining endpoint gaps after client
  evidence or direct protocol tests.
- Keep SDK details close to the corresponding endpoint in `nwconn.c`, and keep
  broader prioritization/status here in `TODO.md`.


### NCP endpoint audit tracking

Current status:

- `src/nwconn.c` contains a mix of implemented, forwarded, partial, dummy,
  and intentionally unsupported NCP endpoints.
- Endpoint comments should be aligned with the Novell SDK Web documentation,
  SDK headers, the Rust `nwserver` implementation, `lwared`, and the existing
  mars_nwe admin/Pascal code where those sources cover the same call.

Follow-up:

- Keep inline `TODO:` comments only where endpoint behavior is incomplete,
  approximate, intentionally dummy/no-op, or still needs SDK layout
  verification.
- Mirror every real incomplete endpoint in this file so follow-up work remains
  visible outside the source code.
- Do not treat every `return(-1)` in `nwconn.c` as incomplete: many of those
  paths intentionally forward bindery/global-server work to `nwbind`.


### NCP synchronization endpoint audit

Current status:

- The old NCP synchronization endpoint family in `src/nwconn.c` is now
  annotated with Novell SDK endpoint names.
- The existing source already marked this area as not well tested, so the
  comments intentionally keep that compatibility warning visible.
- `NCP 0x03`, `0x05`, `0x06`, `0x07`, `0x08`, `0x09`, `0x0a`, `0x0b`,
  `0x0d`, `0x0e`, `0x1a`, and `0x1e` have local implementations.

Follow-up:

- Verify the implemented file/logical-record/physical-record calls against the
  Novell SDK request/reply layouts and a real DOS requester or direct test
  caller.
- Continue direct requester or NWTESTS coverage for the file, logical-record,
  and physical-record synchronization calls that are now wired.
- Verify timeout and error-code behavior for set-oriented locking calls against
  a real requester, especially where MARS-NWE currently relies on the existing
  underlying share implementation.

### AFP Set File Information timestamp coverage

Current status:

- AFP Set File Information (`0x09`) and AFP 2.0 Set File Information (`0x10`)
  now accept the file modification timestamp bitmap (`0x0010`) for path-backed
  file requests.
- Timestamp writes are routed through the existing NetWare `nw_utime_node()`
  helper so trustee Modify rights and the established Unix `utime(2)` fallback
  behavior are reused instead of inventing AFP-specific timestamp handling.
- The Linux smoke helper verifies the AFP date/time fields via the follow-up
  Get File Information response, and the smoke suite also records `stat -c %Y`
  for the backing Unix file.

Follow-up:

- Add directory timestamp handling once the shared AFP path/object resolver grows
  directory-specific Set File Information semantics.
- Keep create/access/backup timestamp writes disabled until their exact AFP to
  NetWare/Unix metadata mapping is deliberately wired and tested.
- Keep Delete/Rename/Create/Remove for later patches that can reuse the existing
  NetWare server helpers and trustee checks.

### Extended volume information field mapping

Current status:

- `NCP 0x16/0x33 Get Extended Volume Information` returns the documented
  `NWVolExtendedInfo` reply and fills the core fields that can be derived from
  generic Unix filesystem statistics.
- NetWare-specific fields that MARS-NWE does not currently model are returned
  as zero for now instead of guessed values.

Follow-up:

- Fill additional `NWVolExtendedInfo` fields when reliable data is available
  from the backing filesystem or from MARS-NWE metadata.
- Candidate fields include suballocation, deleted-file/limbo accounting,
  compression counters, migration counters, EA counters, Directory Services
  object id, and last-modified timestamp data.
- Treat compression-related fields as real follow-up work rather than permanent
  zeroes; populate them only when the backing filesystem exposes trustworthy
  compressed-file or compressed-block accounting.

### Object disk restriction fallback coverage

Current status:

- `NCP 0x16/0x29 Get Object Disk Usage And Restrictions` keeps the existing
  `QUOTA_SUPPORT` split.
- With quota support enabled, the endpoint is routed through `nwbind` so the
  bindery Object ID can be mapped to a Unix uid before querying the quota
  backend.
- Without quota support, the endpoint returns the SDK-compatible fallback:
  unrestricted (`0x40000000`) and no space in use.

Follow-up:

- Add direct tests for both build modes.
- Verify the quota-enabled path against a real Unix quota setup.
- Verify that the quota-disabled fallback remains compatible with requesters
  and with the WebSDK rule for invalid object IDs.

## Printing / Queue backend

### Q_UNIX_PRINT backend status

Current status:

- Queue metadata handling and the `Q_UNIX_PRINT` backend are intentionally separate.
- The backend can already call `/usr/bin/lp`, `lpr`, or a custom script.

Follow-up:

- Improve logging around queue job submission to the Unix print command.
- Capture and expose backend exit status where possible.
- Consider direct CUPS integration only if MARS_NWE needs CUPS job IDs, cancellation, or status polling. Do not add a hard CUPS dependency for basic queue compatibility.

### Transaction Tracking System (TTS)

Current status:

- `NCP 0x22/0x00 TTS Is Available` reports the WebSDK-documented
  unavailable status.
- MARS-NWE does not currently implement TTS rollback semantics, transaction
  files, transaction status tracking, or the begin/end/abort transaction
  state machine.
- Other TTS subfunctions remain unsupported instead of pretending to succeed
  without real transaction tracking.

Follow-up:

- Implement TTS only if a concrete client requires it.
- Treat this as a real transaction subsystem, not as a completion-code shim:
  the WebSDK TTS calls include begin/end/abort transaction, status, threshold,
  and control/statistics operations.

### AFP / Mac namespace backend

Current status:

- `NCP 0x23` still returns invalid namespace for AFP calls that are not implemented yet.
- `AFP Get Entry ID From Path Name` is implemented when the optional
  Netatalk/libatalk backend is available.  Linux smoke coverage exists in
  `tests/linux/afp_entry_id_smoke` and has been verified against `SYS:`,
  `SYS:PUBLIC`, `SYS:SYSTEM`, and `SYS:BURST` with stat-derived fallback
  entry IDs.
- `AFP Get Entry ID From Name` is implemented for the same path-backed
  smoke mode.  Linux smoke coverage uses `tests/linux/afp_entry_id_smoke --from-name`
  and has been verified against `SYS:`, `SYS:PUBLIC`,
  `SYS:SYSTEM`, and `SYS:BURST` with stat-derived fallback entry IDs.
- `AFP Get File Information` is implemented for read-only path-based requests.
  Linux smoke coverage exists in `tests/linux/afp_file_info_smoke` and has
  been verified against `SYS:`, `SYS:PUBLIC`, `SYS:SYSTEM`, and `SYS:BURST`.
  The same test verifies the AFP 2.0 Get File Information subfunction via
  `--afp20` against the same paths, using the same path-backed read-only reply
  for now.  The current reply fills stat/libatalk-derived fields and leaves
  persistent CNID Parent ID / fuller Mac namespace metadata as future work.
- `AFP Scan File Information` (`0x0a`) and `AFP 2.0 Scan File Information`
  (`0x11`) are implemented for path-backed read-only directory scans.  Linux
  smoke coverage exists in `tests/linux/afp_scan_info_smoke`; the helper
  defaults to the AFP 2.0 subfunction and uses `--afp10` for the older
  endpoint.  Runtime coverage has been verified against `SYS:PUBLIC` by
  walking multiple directory entries with the returned `next_last_seen` AFP
  Entry ID continuation value.  The verified AFP 2.0 and older `0x0a` first
  records both return `pmdflts.ini` (`entry_id=0x23c8787d`, `data_len=8161`)
  on the sample tree, and an AFP 2.0 continuation with that Entry ID returns
  `ohlogscr.bat` (`entry_id=0x260437f6`, `data_len=1296`).
- `AFP Get Entry ID From NetWare Handle` is implemented for read-only data-fork
  file handles that are opened in the same client connection.  Linux smoke
  coverage uses `tests/linux/afp_entry_id_smoke --from-handle` and has been
  verified against `SYS:PUBLIC/pmdflts.ini` and `SYS:PUBLIC/ohlogscr.bat`,
  returning volume 0, `fork=0`, and stat-derived fallback Entry IDs for now.
- `AFP Open File Fork` is implemented for the same path-backed smoke subset.
  Raw `VOL:`-style paths resolve the effective NetWare volume from the path
  prefix instead of assuming volume 0, so the same smoke path can cover `SYS:`
  and non-`SYS:` volumes.  It opens only the data fork read-only and returns a
  normal six-byte NetWare file handle plus the current data-fork length; the
  Linux smoke helper
  `tests/linux/afp_open_file_fork_smoke` closes the returned handle in the same
  connection.  Runtime smoke coverage is green for
  `SYS:PUBLIC/pmdflts.ini` (`fork_len=8161`) and `SYS:PUBLIC/ohlogscr.bat`
  (`fork_len=1296`) using `fork=0` and read access `0x01`.  The smoke suite
  now also asserts that write-open requests fail with completion `0x84` and
  resource-fork opens fail with completion `0x9c`, keeping the current
  unsupported cases explicit until AppleDouble/resource-fork, AFP write-open,
  and persistent CNID/base-ID semantics are available.
- `AFP Alloc Temporary Directory Handle` is implemented for the same
  path-backed smoke subset.  Raw `VOL:`-style paths resolve the effective
  NetWare volume from the path prefix instead of assuming volume 0.  Linux
  smoke coverage exists in
  `tests/linux/afp_temp_dir_handle_smoke`; runtime smoke coverage is green for
  `SYS:`, `SYS:PUBLIC`, `SYS:SYSTEM`, and `SYS:BURST`.  The helper returns a
  temporary NetWare directory handle plus the AFP one-byte access-rights mask
  and immediately deallocates the handle in the same connection.  Server
  diagnostics log the wider internal NetWare effective-rights mask, so
  privileged directories can show `rights=0x1ff` while the client prints
  `rights=0xff`.  Entry-ID-only allocation remains TODO until persistent
  CNID/base-ID lookup exists.
- `AFP Set File Information` (`0x09`) and `AFP 2.0 Set File Information`
  (`0x10`) are implemented only for path-backed file metadata smoke writes:
  the FinderInfo bitmap (`0x0020`) and the AFP
  Attributes bitmap (`0x0001`) restricted to Finder Invisible, System, and
  Archive.  Archive is mapped to the existing NetWare `FILE_ATTR_A` attribute
  path, while Invisible and System remain mars_nwe AFP metadata xattr bits.  Linux
  smoke coverage exists in `tests/linux/afp_set_file_info_smoke`; runtime
  FinderInfo coverage is green for `SYS:PUBLIC/pmdflts.ini` with Finder type
  `TEXT` and creator `MARS`.  The helper writes 32 bytes of FinderInfo to
  `org.mars-nwe.afp.finder-info`, stores AFP-only Invisible/System bits in
  `org.mars-nwe.afp.attributes`, maps Archive through the existing NetWare
  attribute store, and verifies the result through AFP 2.0 Get File Information.  The smoke-suite report helper now includes AFP 2.0 FinderInfo, legacy AFP `0x09` FinderInfo, AFP 2.0 Invisible/System/Archive set/clear probes,
  and legacy AFP `0x09` Invisible set/clear probes, and has green
  `failures=0` runs for `SYS:PUBLIC/pmdflts.ini`; the latest run was from the
  build-tree copy of `afp_smoke_suite.sh` after the CMake sync fix and confirms
  legacy `0x09` FinderInfo plus legacy `0x09` Invisible set/clear in the same
  report as AFP 2.0 `0x10`.  It confirms the corrected FinderInfo payload
  alignment by reading
  `user.org.mars-nwe.afp.finder-info=0x544558544d415253...` (`TEXTMARS` with no
  leading padding byte), confirms attribute set/clear via the versioned
  attributes xattr ending clean at `0x01000000`, and confirms the cached
  Entry ID xattr (`0x010000001ad06d3e` in the latest run).  The first stat-derived AFP entry id
  for a path is now cached in the versioned `org.mars-nwe.afp.entry-id` xattr; a
  `fallback` marker on that first verification Get File Information diagnostic
  describes the entry-id origin, not the FinderInfo write result.  Follow-up
  probes should read the cached mars_nwe entry id and omit the fallback marker.
  System remains on the narrow AFP xattr-only attribute path, while Archive is
  routed through the existing NetWare attribute path; runtime probes verified
  System set/clear and Archive set/clear with AFP-visible attrs `0x0004`,
  `0x0000`, and `0x0040`, with server diagnostics showing the matching WebSDK
  SETCLR forms `0x8004`, `0x0004`, `0x8040`, and `0x0040`.  A post-fix
  full-suite run against the rebuilt server completed with `failures=0` and the
  final `user.org.mars-nwe.afp.attributes=0x01000000`, confirming that Archive
  is no longer duplicated in the AFP metadata xattr after Clear Archive.  The smoke
  helper verifies the targeted attribute bit by mask instead of comparing the
  full AFP attribute word, because other stored metadata bits such as System may legitimately remain set while
  another bit is being tested, and Archive may be supplied by the NetWare
  attribute store.  The earlier
  smoke-helper `--backup` spelling is only kept as an alias; new docs and the
  suite use Archive to avoid confusing this AFP attribute with the separate
  backup date/time fields.  All other Set File Information bits and AFP attribute bits remain
  rejected until their write/enforcement semantics are explicitly designed.
- The AFP dispatcher now decodes the WebSDK/NWAFP subfunction number in
  diagnostics so real client probes can be mapped to the corresponding AFP
  call before implementation work starts.
- Optional build-time detection/linking for Netatalk/libatalk exists as a first
  local metadata backend hook. It is deliberately not an AFP protocol
  implementation yet.
- Existing mars_nwe private xattr payloads use the `org.mars-nwe.<domain>.*`
  namespace (`org.mars-nwe.netware.archive` and `org.mars-nwe.netware.fileinfo`) rather than
  the unreleased test-only `user.mars_nwe.*` names.  There is no legacy read
  fallback because the old names never shipped outside local test systems.
  On Linux, mars_nwe's local xattr helper maps source-level `org.mars-nwe.<domain>.*`
  names to the portable `user.org.mars-nwe.<domain>.*` storage namespace, mirroring
  Netatalk's `org.netatalk.*` EA abstraction.
- NetWare AFP calls are NCP entry points for Mac namespace semantics on a
  NetWare volume, not transport-level AFP proxy calls to `afpd`.
- AFP Get DOS Name From Entry ID (0x12) is implemented as a conservative
  read-only reverse lookup over the existing mars_nwe volume table and the
  `nwatalk_get_entry_id()` metadata probe.  It returns the DOS/NetWare path
  relative to the requested volume for entries that already have a cached
  mars_nwe/Netatalk AFP ID, and deliberately does not create fallback IDs while
  scanning a volume.

Follow-up:

- Implement the NetWare AFP NCP calls locally, using libatalk helpers rather
  than proxying requests to `afpd`.
- Candidate libatalk pieces include the new AppleDouble/Finder Info/resource
  fork helper wrappers, plus future CNID/directory-id helpers, attribute
  mapping, and filename conversion.
- Keep returning invalid namespace for AFP calls that still lack a real per-volume Mac
  namespace/AFP metadata layer. Do not return success for additional AFP calls without
  data/resource fork and Finder Info semantics.
- Replace the compatibility stat-derived AFP entry-id generator with a real
  CNID/directory-id allocator once the libatalk/CNID backend is integrated.
- mars_nwe-owned AFP entry ids are probed first from the versioned
  `org.mars-nwe.afp.entry-id` xattr before consulting Netatalk/libatalk
  AppleDouble/CNID metadata.  If neither source has an id, mars_nwe derives the
  existing stat-compatible id and caches it in that xattr so subsequent probes
  can use persistent mars_nwe metadata.  Linux smoke coverage confirms the
  versioned xattr payload shape, for example `0x010000007b9c42e1` for a cached
  `0x7b9c42e1` Entry ID.  AFP directory-scan continuation remains directory
  iteration based: `last_seen` skips past the previously returned object, but
  the next returned Entry ID is not required to be numerically greater than the
  continuation token.  FinderInfo plus the Finder Invisible/System/Archive AFP attributes now have
  deliberately narrow write paths through AFP Set File Information `0x09` and
  AFP 2.0 Set File Information `0x10`; CNID
  allocation and broader AFP metadata writes still need a deliberate write-safe
  design.
- Put additional future mars_nwe-owned AFP metadata under `org.mars-nwe.afp.*`
  (or a compact `org.mars-nwe.afp.metadata` record) and keep Netatalk-owned
  metadata under Netatalk's own `org.netatalk.*` keys.
- Extend the Linux AFP smoke tests once additional AFP subfunctions are
  implemented, especially Finder Info updates, fork open/read/write paths,
  resource-fork handling, and broader directory-scan edge cases.


### AFP implementation convergence plan

Current status:

- The AFP/NWAFP work is now broad enough that future endpoint patches should
  treat AFP as an Apple-facing adapter over the existing mars_nwe NetWare
  server machinery rather than as a parallel file server implementation.
- The safe baseline already includes path-backed Entry ID, Get/Scan File
  Information, temporary directory handles, read-only data-fork Open File
  Fork, narrow Set File Information metadata writes, NetWare-backed Archive
  attribute mapping, Modify timestamp writes through `nw_utime_node()`, and
  a conservative Get DOS Name From Entry ID reverse lookup.
- The Get DOS Name From Entry ID helper now returns the canonical DOS namespace
  spelling from the existing mars_nwe `namedos.c` alias builder.  The follow-up
  smoke run confirms `PUBLIC/PMDFLTS.INI` for `SYS:PUBLIC/pmdflts.ini`, replacing
  the earlier raw Unix/realcase `public/pmdflts.ini` result.

Design rule:

- AFP request handlers should parse the WebSDK/NWAFP request, resolve volume,
  path, directory handle, or entry id to an existing mars_nwe object, call the
  established NetWare helper, and translate the result into the AFP reply
  layout.
- Do not introduce direct `open(2)`, `unlink(2)`, `rename(2)`, `mkdir(2)`,
  `utime(2)`, attribute, trustee, or directory-scan logic inside AFP handlers
  when a mars_nwe helper or wrapper already exists.
- Only keep AFP-specific storage for metadata that has no NetWare equivalent,
  such as FinderInfo, AFP Entry IDs/CNIDs, and narrowly scoped AFP-only
  attributes that are deliberately not mapped to NetWare attributes yet.

Refactor/wrapper follow-up:

- Add a shared AFP object resolver that handles raw `VOL:PATH`, directory-handle
  relative paths, volume plus entry id, and the WebSDK path modifier forms by
  reusing existing mars_nwe volume, namespace, and directory-handle helpers.
- Route all AFP writes through existing mars_nwe policy checks before changing
  metadata.  Archive and Modify timestamp already do this through NetWare
  helpers.  FinderInfo and AFP-only Invisible/System xattr writes are now gated
  by the same trustee/effective-rights Modify policy before the AFP metadata
  xattrs are updated.
- Continue moving AFP-visible NetWare attributes onto the existing NetWare
  attribute store.  Archive is already mapped to `FILE_ATTR_A`; ReadOnly,
  Hidden, System, ExecuteOnly, and Shareable still need either a real mapping
  through existing attribute helpers or an explicit unsupported result.
- Extend Set File Information timestamps only through existing mars_nwe helpers:
  Modify is routed through `nw_utime_node()`, while Create, Access, and Backup
  Date/Time must be checked against existing NetWare/archive metadata support
  before being enabled.
- Normalize Get/Scan File Information so each field comes from the existing
  mars_nwe source of truth where possible: NetWare attributes, effective rights,
  file size, timestamps, owner information, archive date/time, FinderInfo,
  resource-fork size, and Entry ID/CNID metadata.
- Revisit Scan File Information after the resolver work and prefer mars_nwe's
  existing directory/search machinery over the current AFP-local directory walk
  for search attributes, namespace filtering, and multi-record replies.
- Replace the current volume-walk Get DOS Name From Entry ID path with a real
  Entry ID/CNID index or an existing canonical path lookup once the entry-id
  backend grows beyond xattr/stat-derived compatibility IDs.


AFP Set File Information metadata-rights convergence:

- AFP FinderInfo writes and AFP-only Invisible/System attribute xattr writes no
  longer bypass NetWare policy just because their storage is AFP-specific.
  `afp_set_file_information()` now checks the resolved file through the existing
  trustee/effective-rights Modify policy before writing `org.mars-nwe.afp.*`
  metadata.
- Archive continues to route through the NetWare attribute helper (`FILE_ATTR_A`),
  and Modify timestamp continues to route through `nw_utime_node()`.  The new
  check only covers metadata that has to remain AFP-specific, keeping AFP as an
  Apple-facing adapter over mars_nwe policy rather than a parallel file server.
- The Linux AFP smoke suite now has optional negative coverage for this policy
  gate.  With `--readonly-user NOPASSUSER --readonly-no-password`, the suite can
  run FinderInfo, Invisible, and System writes as a user that is expected to lack
  Modify rights and assert completion `0x8c`.  With `--prepare-readonly-rights`,
  the suite uses the existing ncpfs `nwgrant`/`nwrevoke` trustee utilities to
  grant only read/file-scan rights (`[RF]` by default) before the negative probe
  and revoke the explicit trustee assignment afterwards.
- Runtime status: the negative smoke has been verified with `NOPASSUSER` as a
  no-password test user.  The suite temporarily granted `[RF]` on
  `SYS:PUBLIC/pmdflts.ini`, confirmed FinderInfo, Invisible, and System Set
  File Information requests are rejected with completion `0x8c`, and then
  successfully revoked the temporary trustee assignment.  The same run ended
  with `failures=0`, preserved the final `TEXT/MARS` FinderInfo xattr, kept
  `org.mars-nwe.afp.attributes` clear after the attribute cleanup probes, and
  left the Modify timestamp at the expected smoke value.

Endpoint order:

- First finish the non-destructive convergence work above.
- Then implement AFP Create File (`0x02`) and AFP 2.0 Create File (`0x15`) by
  routing through the existing NetWare create/open path and testing only
  explicit temporary smoke files with cleanup.
- Then implement AFP Create Directory (`0x01`) and AFP 2.0 Create Directory
  (`0x14`) through the existing NetWare directory-create helper, again only on
  temporary smoke paths.
- Then implement AFP Rename (`0x07`) through the existing NetWare rename/move
  path, preserving FinderInfo/xattrs and checking Entry ID behavior.
- Keep AFP Delete (`0x03`) and Get Macintosh Info On Deleted File (`0x13`) for
  last.  Delete must only be enabled through the existing NetWare delete/erase
  policy path and smoke-tested on self-created temporary files.

## Deferred / optional protocol work

  * Basic Packet Burst file transfer support is implemented and verified with a
    diagnostics-enabled DOS client test.
  * Packet Burst support is built by default, but runtime use remains controlled
    by `nwserv.conf`.
  * Packet Burst/NDS fragmentation support remains out of scope unless a concrete
    client requires it.
