Replace the catalog-read subset packer with the full AFP 2.x file/directory parameter block in core/service/afp/parms.go: fixed fields in ascending bit order (attributes, parent dir id, create/modify/backup dates, 32-byte Finder info, file-number/dir-id CNID, data/resource fork lengths, offspring count, owner/group, access rights) followed by the variable-length name area, with the long/short name fields carrying 2-byte offsets into it -- the layout the legacy service/afp packer produced, now sourced entirely from the section-9 seam. Volume gains FinderInfo (via the fork engine ReadFinderInfo), ShortName (via the NameEngine), and ParentCNID helpers; FPGetFileDirParms, FPEnumerate, FPOpenFork, and FPGetForkParms all pack through vol.fileDirParams. Catalog dates use the spec 2000-GMT epoch consistently, fixing the legacy port's 1904-local-epoch divergence -- recorded in spec/errata.md "AFP catalog date epoch". parms_test.go drives the full file and directory bitmaps and checks each field at its bit-order offset plus the offset-addressed names; the dispatch tests now follow the name offsets rather than reading names inline.

Wire the server-initiated two-phase write (spec/10 "Two-Phase Write Protocol") so a large FPWrite delivers its data over its own ATP transaction rather than relying on data riding inline in the aspWrite command block. This is the path the .XPP driver actually uses for ASPUserWrite, and was the documented "not yet wired" gap in the spine. Flow: phase 1 aspWrite (SPFunc 6) WS -> server, FPWrite header only phase 2a aspDataWrite (7) server -> WS, "send N bytes" (TReq) phase 2b data response WS -> server, TResp packets (data) phase 3 final reply server -> WS, reply to the aspWrite The server is the *initiator* of phase 2a, so the spine now sends a TReq of its own and correlates the workstation's TResp back to the pending write. New core-ring pieces: - write.go: pendingWriteTable keyed by the transaction id the server stamps into the aspDataWrite TReq (the WS echoes it in its TResp), and the pendingWrite in-flight state (original aspWrite TReq, FPWrite block, bytes wanted, accumulated data). - asp.go: handleWrite (phase 1 — parse FPWrite reqCount, register the pending write, send the aspDataWrite via the originating port's Unicast); handleDataResponse (phase 2b->3 — accumulate TResp data by arrival, run the FPWrite on EOM/want-reached, reply to the original aspWrite). A zero-reqCount write completes inline with no round-trip. - atp.go: parseATPResponse decodes the inbound TResp the spine previously dropped; afp.go Inbound routes TResp to handleDataResponse. - forkio.go: writeDataCount reads reqCount from an FPWrite header; appendWriteData splices the collected data onto the 12-byte header so afpWrite (which reads data inline) is reached unchanged. Storage is still touched only through the fork engine; the two-phase machinery is pure ASP/ATP transport with no AppleDouble/EA knowledge. write_test.go drives single-packet, multi-packet (data spanning two TResps), and zero-length writes end-to-end over a recording port that captures the server-initiated aspDataWrite TReq.

…dIcon Add the AFP Desktop database commands to the core/service/afp dispatch spine (Inside Macintosh: Networking, AFP 2.x §C): FPOpenDT/FPCloseDT, FPGetComment/FPAddComment/FPRemoveComment, FPAddIcon/FPGetIcon/ FPGetIconInfo, and FPAddAPPL/FPRemoveAPPL/FPGetAPPL. The slice keeps the §9 storage seam honest by splitting the database: - Comments ride the fork seam (v.FS().ReadComment/WriteComment), so a comment lives in the same metadata container (AppleDouble sidecar, NTFS stream, Netatalk EA) as the file it annotates and survives a rename through the FS, exactly like Finder info. RemoveComment writes an empty comment; GetComment on a file with none returns kFPItemNotFound. - Icons + APPL mappings have no per-file home in the seam, so they live in a per-volume in-memory desktopDB (built lazily on first FPOpenDT). Persistence is an adapter concern (like the mem metastore standing in for sqlite); core stays free of database/path knowledge. FPAddIcon is command 192 -- the Mac delivers it over the two-phase ASPWrite path (the bitmap is bulk write data). writeDataCount/ appendWriteData now recognise the 20-byte FPAddIcon header alongside FPWrite's 12-byte one, so the same data path serves both; pendingWrite gains the header length to splice the data back on. FPOpenDT hands out a per-session DTRefNum->volume mapping (dtTable); every later Desktop command carries it. The Desktop machinery is pure protocol + volume state -- storage is touched only via the fork seam. desktop_test.go covers OpenDT/CloseDT, the comment round-trip (+ the missing-comment item-not-found path), the FPAddIcon two-phase path -> GetIcon/GetIconInfo over a recording port, and the APPL round-trip. spec/errata "Desktop database persistence" documents the comment/icon split, the FPAddIcon-via-ASPUserWrite path, and the catalog-vs-comment path-encoding convention.

Wire FPCatSearch (command 43), the last AFP-specific command the "Remaining M7" notes called out, into the core/service/afp dispatch spine. It is the protocol behind the Finder's "Find File". The spine has no on-disk catalog index, so it walks the live catalog through the §9 FileSystem seam (Volume.Enumerate, depth-first into every subdirectory) and packs each match with the same fileDirParams packer the catalog-read commands use -- so CatSearch carries no storage-layout knowledge. It decodes the real wire request (reqMatches, the opaque 16-byte CatalogPosition cursor, file/dir result bitmaps, reqBitmap, spec1/spec2) and honours the criteria the field exercises: PartialName (case-insensitive substring), FullName (case-insensitive exact), and ParentDirID. A zero reqBitmap matches everything. Criteria bits not modelled (date/length ranges, Finder-info mask) are ignored rather than rejected -- a lenient posture that never false-negatives the dominant name search. Paging: the cursor carries a flat depth-first visit index; a page returns up to reqMatches records capped at ~4 KB (one ASP quantum). More results pending -> NoErr + next index; last page -> kFPEOFErr + zero cursor (AFP/Netatalk convention). A resumed search re-walks but skips already-returned entries, so pages neither repeat nor drop. Unlike the legacy service/afp port (which delegated to a backend FileSystem.CatSearch with a flattened printable-substring query and a required capability flag), the spine decodes spec1/spec2 itself and walks any backend, so memfs/local_fs search with no bespoke index. catsearch_test.go covers a partial-name search finding matches across the tree (root + subdir), a full-name exact match rejecting substrings, and a paged search that resumes via the cursor without repeats. spec/errata.md documents the seam walk, the lenient criteria, the cursor/paging scheme, and the divergence from the legacy port. afp.go package doc + start log updated.

The first CatSearch slice wrongly baked "walk the tree and substring-match names" into the AFP spine. But CatSearch semantics belong to the FileSystem backend -- and a backend may decline it. A synthetic backend redefines search entirely: MacGarden turns a CatSearch into an explicit query against its upstream archive and materialises the HTML results as virtual folders/files, entries an Enumerate of the volume would never surface. Move the capability into the seam: core/fs: - CatSearcher optional interface + CatSearchCriteria (name partial/full, parent path, free-text Query for synthetic backends, Max) / CatSearchResult (path + FileInfo) / CatSearchCursor (backend-opaque page token) DTOs + ErrCatSearchUnsupported. - WalkCatSearch: the default depth-first predicate walk a plain hierarchical backend opts into in one line (local_fs, memfs do). Lives in core/fs so it is reusable and the file service stays storage-agnostic. - shareFS forwards CatSearch to a base that implements CatSearcher; Capabilities().CatSearch gates support. memfs/local_fs advertise + delegate to WalkCatSearch. core/service/afp: - afpCatSearch now decodes the AFP wire criteria (spec1/spec2) into fs.CatSearchCriteria, resolves the parent dir id to a store path, and DELEGATES to vol.FS() via the CatSearcher capability -- returning kFPCallNotSupported when the backend declines. It packs whatever store paths the backend returns with the existing fileDirParams packer, and round-trips the backend's opaque cursor through the 16-byte CatalogPosition verbatim (the spine never interprets it). The fixed tree-walk is gone from AFP. Tests: core/fs/catsearch_test.go covers WalkCatSearch (partial across tree, paged without repeats, parent scope) and shareFS reporting ErrCatSearchUnsupported for a non-searching base. The AFP catsearch_test.go drives the same three scenarios end-to-end over the delegated memfs backend and now round-trips the opaque cursor. spec/errata.md rewritten to document that CatSearch is the implementor's to define (including not to support). Note: archtest is currently red from a PRE-EXISTING encoding/binary import in core/fs/fork_ads.go + fork_xattr.go (landed in 47da010 / 1a03dc4, masked by a cached result); this commit neither adds nor fixes that -- it is a separate cleanup. This commit's own files use no forbidden imports. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…archtest green
The core ring bans encoding/binary (it transitively imports reflect, which the
no-reflection rule forbids; §1 / archtest), so a dozen core packages each
hand-rolled their own be16/putLE32/appendBE16/... — the same shifts duplicated
everywhere, and three files had drifted back to encoding/binary outright,
turning archtest red (the failure was masked by a cached result).
Consolidate the byte-order primitives into one dependency-free, reflection-free
package, core/binaryprimitives, providing every width and order in the three
call styles the codebase actually uses:
- readers: BE16/BE32/BE64, LE16/LE32/LE64
- in-place Put*: PutBE16/.../PutLE64 (write into a pre-sized slice)
- append Append*: AppendBE16/.../AppendLE64 (grow and return)
Migrate every hand-rolling package to it and delete the local helpers:
appledouble, fs (fork_ads/fork_xattr), metastore, link/bridge,
protocol/{ddp,atp,smb,netbios,netbeui}, service/{zip,rtmp,afp}, and
adapter/capture/pcapfile (adapters may use it too — it is safe for every ring).
This also clears the archtest violations at the root: the encoding/binary
imports in core/appledouble + core/fs/fork_{ads,xattr} are gone (they cascaded
to fs/share/afp/smb), and a stray fmt.Fprintf("%02X") in core/fs/codec.go —
fmt also pulls reflect transitively — is replaced with a hand-rolled hex
formatter. archtest is green again.
.refactor/00-DESIGN.md documents the package and the "don't re-hand-roll
endian helpers" rule under the no-reflection discipline, including the fmt
caveat.

Wire the SMB1 session-establishment dispatch into core/service/smb, the SMB
analogue of the AFP ASP-session + login + open-volume spine that landed first.
Filesystem commands (NtCreate/Read/Write/Close, Trans2 find/query) come in a
later slice; this lands the connection state machine a client walks before any
file I/O.
Transport-independent: Service.Dispatch(sess, req) decodes one SMB message via
the core/protocol/smb header codec and demuxes by command. The NetBIOS /
transport seam (which frames session messages) will call Dispatch; the spine
holds no transport knowledge, so it is unit-tested directly over raw SMB
frames. Commands handled:
- NEGOTIATE -> accept NT LM 0.12 (WCT=17), conservative caps/buffer
set tuned for Win9x (no CAP_RAW/MPX), user-level
security with no challenge.
- SESSION_SETUP_ANDX -> grant a guest session (UID=1, Action=guest). This is
a compatibility server: no credential check (the honest
weakness, documented in the package doc).
- TREE_CONNECT[_ANDX] -> bind a TID to a *Share (case-insensitive name match)
or the virtual IPC$ pipe tree; unknown share ->
STATUS_BAD_NETWORK_NAME.
- TREE_DISCONNECT / LOGOFF_ANDX / ECHO.
- any FS command -> STATUS_NOT_SUPPORTED (definite reply, not a hang) until
the FS engine slice lands.
session.go holds the per-connection smbSession (UID, TID -> treeConnect{share|
ipc}, allocators) binding a *Share directly (the §9 seam) rather than a share
index, so a share removed from the Manager mid-session rides out on the held
pointer. negotiate.go carries the faithful wire formats (mirroring the legacy
service/smb/command_core.go byte layouts validated against Win9x/WfW) and the
DOS<->NTSTATUS mapping; integer codecs come from core/binaryprimitives.
smb.go gains SetWorkgroup (NEGOTIATE domain), a case-insensitive ShareByName,
and the updated package doc. dispatch_test.go drives NEGOTIATE,
SESSION_SETUP_ANDX (guest UID), TREE_CONNECT_ANDX (bind + unknown-share
refusal), TREE_DISCONNECT, the not-supported FS path, and a non-SMB drop.

docs: M7 TODO — CatSearch (capability), core/binaryprimitives, SMB session spine Record the slices landed since the desktop-database note: FPCatSearch as an optional fs.CatSearcher capability (7515477 + reshape 1cb4c08 — AFP command set now complete), the core/binaryprimitives endian consolidation that restored archtest green (c5de757), and the SMB session-establishment spine (e593271). Refresh the encoding/binary errata to point at core/binaryprimitives (with the fmt-pulls-reflect caveat) instead of the now-migrated per-package helpers, and revise "Remaining M7" to the SMB FS command engine + NetBIOS->SMB session-data seam as the next steps. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> @
Two M7 file-services slices over the §9 storage seam.
SMB FS command engine (core/service/smb): serve the file/path/find
commands over the bound *Share's FS, not just session establishment.
OPEN[_ANDX]/CREATE, READ[_ANDX]/WRITE[_ANDX], CLOSE/FLUSH, DELETE/RENAME,
CREATE/DELETE/CHECK_DIRECTORY, QUERY_INFORMATION[_DISK], and the TRANS2
FIND_FIRST2/FIND_NEXT2/FIND_CLOSE2 + QUERY_PATH/FILE_INFO subcommands.
Every path reaches storage only through sh.FS(); RENAME/DELETE ride the
metadata-carrying FS().Rename/Remove. Per-request UTF-16/ANSI charset
threads through the share codec. Per-conn FID + search tables; TID-
disconnect and conn-end close leaked handles. The legacy DOS-name-
mangling fuzzy resolver is dropped (deferred to a core/fs NameEngine);
documented in spec/errata.
NetBIOS→SMB session-data seam (core/service/netbios): the missing
inbound-frame delivery. NewNBFEngine builds the responder-side NBF
(NetBEUI) virtual-circuit state machine, registered on the
core/router/netbeui mini-router as its NameHandler + SessionHandler. It
answers a CALL, completes establishment, reassembles each SMB message,
routes it to the installed SessionConsumer (SMB, via conn.go's
NewConn/Conn — one smbSession per circuit), and sends the response back
fragmented over DATA frames. SESSION_END and Stop close the circuits.
The seam is two small interfaces (SessionConsumer/SessionCircuit); the
engine reaches the wire only through a FrameSender seam and the upper
layer only through SessionConsumer — no link or SMB knowledge either way
(§3-bis command-core / session-transport split). Core re-home of the
legacy service/netbios/over_netbeui session half.
cs-tinygo blank-imports core/service/{afp,smb,netbios} so the file
services stay embedded-compilable. archtest + full tagged suite green.

Add the second NetBIOS session transport feeding the same upper-layer SessionConsumer/SessionCircuit seam the NBF engine uses, so SMB rides NWLink (NetBIOS-over-IPX) as well as NetBEUI. core/service/netbios/nbipx.go — ipxSessionEngine, the IPX parallel of the NBF engine: responder-side NB-IPX session state machine. Accepts SESSION_INIT (→ SESSION_CONFIRM carrying our connection ID; circuit keyed by peer IPX address + the remote's SourceConnID), reassembles DATA_FIRST_MIDDLE/ DATA_ONLY_LAST(EOM) segments off the 16-byte NBIPXSessionHeader, serves the whole SMB message to the consumer, replies as one EOM DATA_ONLY_LAST, and on SESSION_END closes the conn + SESSION_END_ACKs. Reaches the wire only through the DatagramSender seam (the core/router/ipx mini-router's Send) and the upper layer only through SessionConsumer — no router/port/SAP or SMB import. It is the core re-home of the legacy service/netbios/over_ipx transport's session half, stripped of netlog + the router/SAP coupling. session.go gains NewIPXEngine + the exported IPXEngine handle (HandleDatagram/ closeCircuits, satisfying core/router/ipx.SocketHandler). netbios.go now tracks engines as a circuitCloser set (both *Engine and *IPXEngine) so Stop tears down circuits of either transport; package doc covers both. NB-IPX name-query/NMPI/mailslot-datagram paths stay out of this engine — they are name/datagram-layer concerns, not the session data path SMB rides. nbipx_test.go drives INIT-establishment, non-PEP ignore, data→consumer→reply, segment reassembly, and SESSION_END + Stop teardown over the REAL core/router/ipx mini-router with a recording port; compile-asserts *IPXEngine satisfies ipxrouter.SocketHandler. go list -deps ./core/router/ipx carries no service/netbios, so the assertion is acyclic. cs-tinygo already blank-imports core/service/netbios, so the new engine's embedded-compilability is covered. gofmt + vet clean, archtest green (uncached), default + -tags all builds pass, full go test ./... green.

…X capture-replay
Finish the in-core M7 file-services command engines (the items finishable at
the command-engine altitude; §10d and legacy deletion stay gated on later
milestones — see TODO).
SMB NT_CREATE_ANDX (core/service/smb/ntcreate.go) — the NT/2000/XP
open-or-create path, the open a real Windows client uses. Over the bound
*Share's FS it honours CreateDisposition (SUPERSEDE/OPEN/CREATE/OPEN_IF/
OVERWRITE/OVERWRITE_IF, gated against existence) and the FILE_DIRECTORY_FILE /
FILE_NON_DIRECTORY_FILE CreateOptions (opens files AND directories; a directory
FID carries no open fork.File). DesiredAccess maps to a read-only/RW handle the
WRITE path enforces; the WCT=34 reply packs the four NT timestamps, ext-attrs,
alloc/EOF sizes and the Directory flag. Storage reached only via sh.FS().
ntcreate_test.go covers create/collision, open/missing, read-only-handle write
denial, directory create + dir/file mismatch statuses, bad-TID. The dispatch
not-supported probe now uses LOCKING_ANDX (genuinely unimplemented).
NetBIOS datagram + node-status paths (core/service/netbios/nbf_datagram.go) —
the NBF engine's HandleFrame now answers the two connectionless responder paths
alongside the session machine: STATUS_QUERY → STATUS_RESPONSE (node-status name
table built from the engine's own name set, truncated to the requester's
advertised buffer with the more/too-big flags) and DATAGRAM/DATAGRAM_BROADCAST
decoded to names+payload and routed to a new optional DatagramConsumer seam
(SetDatagramConsumer, the datagram analogue of SessionConsumer — a browser/
mailslot service plugs in there without touching the transport; until one does,
datagrams drop after decode). nbf_test.go covers status answer/foreign-ignore/
truncation and datagram deliver/drop.
Capture-replay (core/protocol/netbios/nbipx_capture_test.go) — three real
frames from captures/ipx.pcap decode→re-encode byte-identical: NB-IPX
name-service FIND.NAME, NMPI NAME_CLAIM (0xF1), NMPI MAILSLOT_SEND (0xFC,
carrying the \MAILSLOT\BROWSE browser announcement + embedded SMB). Exercises
the codec the M7 NBIPX session transport rides on.
Deferred and recorded in TODO: §10d same-FS AFP+SMB coordination (needs the
shared bus/FS that M8a builds — today AFP/SMB build separate FS stacks with a
nil bus); the AFP captures are link-layer (LLAP/DDP/AARP) so AFP parity stays
golden-vector tests; locking/MPX/raw stay STATUS_NOT_SUPPORTED; legacy
service/{afp,smb,netbios} deletion is blocked on the M8/M8a→M10 cutover.
gofmt + vet clean, archtest green (uncached), default + -tags all builds pass,
full go test ./... green.

…bject Correct the §10d wording: each service keeps its OWN shareFS instance (AFP needs the AppleDouble fork engine, SMB the bare data fork, each its own codec) even when an AFP volume and SMB share export the same host directory. What they share is the event bus — §10d is publish-on-mutation + Origin-filtered subscribe, one Publish per mutation, many reactors. M8a recognises two specs naming the same host path and hands both share.Build calls one common bus.Bus. The earlier "shared bus/FS" phrasing conflated the two.

…all transports Break the browser out of SMB in the design. The browser (host/domain announce, master-browser elections, GetBackupList, RAP NetServerEnum2 browse list) is a NetBIOS *datagram*-layer service, not part of the SMB *session* protocol — the legacy code wrongly buries it in service/smb. It is the datagram analogue of the §3-bis command-core/session-transport split: one browser command core fed by the DatagramConsumer seam of all three NetBIOS transports (NetBEUI/IPX/NBT), zero per-transport browser code. 00-DESIGN.md: new §3-ter (the browser service + its DatagramConsumer plug-in, the read-only BrowseList() seam SMB's IPC$ \PIPE\LANMAN handler consumes, optional via the §8 registry); package layout adds core/service/browser and adapter/netbios-tcp. 02-PHASE-migration.md: M7's TCP-transport bullet split — smbtcp = direct-TCP :445 only; new adapter/netbios-tcp = NBT (RFC1001/1002, name/datagram/session) feeding the SAME NetBIOS Session+Datagram seams as NBF/NBIPX (most vintage TCP clients use :139, not :445). New M7d step migrates the browser out of service/smb. TODO.md: M7b re-scoped to direct-TCP :445; new M7b2 (NBT adapter) and M7d (browser service) rows. No code changed — design/plan only. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…config value
The NetBIOS computer name is consumed by three services (NetBIOS claims it, SMB
advertises it, the browser announces it), so it must have ONE source of truth.
Today NetBIOS takes serverName via constructor while SMB carries an independent
workgroup and has no server-name field at all — nothing connects them, so config
could let them drift.
Fix is single ownership, not divergence detection: new §4-bis makes server
identity a top-level config.Identity{Hostname, Workgroup} section (alongside
Logging/Router/Bridge), NOT a field on any component section. The registry reads
it once and hands the same Hostname to NetBIOS + SMB (new SetServerName,
advertised in NEGOTIATE — today SMB only has SetWorkgroup) + browser. With no
per-service hostname field, "SMB and NetBIOS names differ" is unrepresentable —
stronger than a cross-section equality check. The model Validate backstops any
externally-surfaced second name (e.g. a hand-edited UCI key) with a clear error —
the requested "error if they vary" guard, as defence-in-depth not the primary
mechanism. Hostname change is restart-grade for NetBIOS (re-claim per transport).
Lands in M8a with the config sections (none exist before then); the disconnect is
known and deliberately not patched piecemeal ahead of the config layer.

No code changed — design/plan only.

…d (SMB runs without NetBIOS) Correct the §4-bis framing: SMB runs without NetBIOS (direct-TCP :445 has no NetBIOS layer; a deployment can be AFP-only or SMB-:445-only with NetBIOS off), so the hostname is a SERVER-level property consumed by NetBIOS/SMB/browser, owned by none — not a "NetBIOS computer name" SMB borrows. Consequences captured: the registry hands Hostname to whichever consumers are enabled (SMB always; NetBIOS only if enabled; browser if linked); a NetBIOS-less server still drives SMB's advertised name from the same field. Validation is layered — a baseline hostname check always applies, but the NetBIOS ≤15-byte / upper-case rule is a CONSUMER constraint enforced only when NetBIOS is enabled (a 20-char name is legal for an SMB-:445 / AFP-only server, rejected once NetBIOS turns on, with NetBIOS named as the constraint source). Hostname change is restart-grade for NetBIOS AND for direct-TCP SMB's advertised name. 00-DESIGN.md §4-bis; 02-PHASE-migration.md M8a bullet; TODO M8a row. Design only.

… AND direct/NetBIOS-less)
SMB runs over IPX two ways, and more broadly its session transports split into
two families that SMB itself does not distinguish (all drive the one
transport-agnostic SessionConsumer seam in conn.go):
NetBIOS-based: NBF (NetBEUI), NBIPX (IPX socket 0x0455), NBT (TCP 139).
Direct (NetBIOS-less): SMB direct-hosted over IPX (socket 0x0550, MS "NWLink
direct host"); direct-TCP (:445).
The direct-IPX path (legacy service/smb/over_ipx_direct, socket 0x0550) is a CORE
transport — no net, no NetBIOS layer — driving the same NewConn/ServeMessage/Close
seam as NBF/NBIPX. So SMB-over-IPX exists both with NetBIOS (NBIPX 0x0455) and
without (direct 0x0550). This is also why server identity is not NetBIOS-owned
(§4-bis): SMB has live transports that never touch NetBIOS.
00-DESIGN.md §3-bis: SMB transports listed as two families; cross-link to §4-bis.
conn.go: seam doc + SessionConsumer comment corrected from "a NetBIOS transport"
to "any session transport (NetBIOS-based or direct)" — comment-only, builds+tests

…sionConsumer seam Add the Microsoft "NWLink direct host" transport: SMB framed straight onto IPX socket 0x0550 (type-4 PEP) with NO NetBIOS layer — the NetBIOS-less sibling of NBIPX (which rides the NetBIOS session engine on 0x0455). So SMB-over-IPX now exists BOTH ways: with NetBIOS (NBIPX 0x0455) and without (direct 0x0550). core/service/smb/directipx.go — *Service.NewDirectIPX(sender) builds the transport. It is connectionless (each IPX datagram carries one whole SMB message, no reassembly) and drives the SAME transport-agnostic SMB SessionConsumer seam (conn.go NewConn/ServeMessage/Close) that NBF/NBIPX use. It keeps one Conn (smbSession) per remote IPX endpoint plus a server-assigned CID ([MS-CIFS] §2.2.1.6.4) allocated on NEGOTIATE, stamped into the SMB header SecurityFeatures field of every response with the request's SequenceNumber mirrored; SMB_COM_ECHO multi-response (N datagrams, incrementing seq) honoured. It reaches the IPX wire only through a local DirectIPXSender seam (the core/router/ipx mini-router's Send satisfies it structurally), so SMB never imports the mini-router — the same acyclicity discipline as the NetBIOS engines (go list -deps ./core/router/ipx carries no service/smb). The SMB Service now tracks transports it owns directly as a circuitCloser set, torn down on Stop. Re-home of legacy service/smb/over_ipx_direct, stripped of the netbios SessionContext coupling and encoding/binary (uses core/binaryprimitives). directipx_test.go drives NEGOTIATE→CID-allocation, circuit-shared-across-messages, ECHO multi-response, response-ingress-drop, non-SMB-drop, and Stop-closes-circuits over the REAL IPX mini-router with a recording port (compile-asserting *DirectIPX satisfies ipxrouter.SocketHandler).

… transports Break the NetBIOS browser out of the legacy SMB service into a standalone datagram-layer service (§3-ter), the datagram analogue of the SMB session command core. One browser, fed by the NetBIOS DatagramConsumer seam, common to NetBEUI/IPX/NBT — SMB carries no browser logic. core/protocol/browser — the [MS-BRWS] wire codec as self-serialising DTOs (CLAUDE.md rule #10): MailslotTransaction (the SMB_COM_TRANSACTION \MAILSLOT\BROWSE envelope), Announcement (host/local-master), DomainAnnouncement, Election (+ Compare: criteria→uptime→lower-name ordering), GetBackupList request/response, AnnouncementRequest, and UnwrapPayload (tolerates the Win9x 2-byte preamble). Reflection-free, core/binaryprimitives-based, round-trip tested. core/service/browser — the command core: a component.Component that IS the NetBIOS DatagramConsumer. HandleDatagram unwraps the mailslot, drops self-sourced loop-backs (the announce/election storm guard), records observed servers (browse list) + machine-group masters, answers AnnouncementRequest, runs the master- browser election (lose→potential+silent; win→transmit loop→after 3 uncontested retransmits become local master + emit a local-master announcement), and answers GetBackupList only while local master (token echoed, sourced from our <1D> name). Exposes the read-only BrowseList()/BackupList() query API SMB's IPC$ \PIPE\LANMAN NetServerEnum2 will consume. Election timers are injectable so the machine is race-tested without real-time sleeps. Outbound seam added to core/service/netbios: Service.SendDatagram fans a Datagram to every transport's datagramEgress; the NBF engine emits a CmdDatagram[Broadcast] UI frame — the outbound mirror of DatagramConsumer. The browser imports core/service/netbios only for the two seam types; go list -deps ./core/service/netbios carries no service/browser (acyclic). cs-tinygo blank-imports both new packages. NBIPX datagram-egress (NMPI mailslot send) and the SMB-side IPC$ NetServerEnum2 consumer (re-home of legacy command_rap_lanman.go calling BrowseList()) are follow-ons. gofmt + vet clean, archtest green (uncached; new core pkgs are reflection/net/ binary-clean), default + -tags all builds pass, full go test ./... green (browser race-tested).

…\PIPE\LANMAN
Wire the SMB side of the browser query: the RAP NetServerEnum2 ("get server
list") clients send over the IPC$ \PIPE\LANMAN pipe inside an SMB_COM_TRANSACTION.
This is the one place the SMB session layer meets the datagram-layer browser
service (§3-ter) — SMB asks the browser for the list and packs the RAP reply; SMB
holds no browser/election logic.
core/service/smb/lanman.go — the SMB_COM_TRANSACTION dispatch case. A TRANSACTION
on the IPC$ pipe whose byte area names \PIPE\LANMAN + RAP function NetServerEnum2
(0x0068) is answered from the browse list via a BrowseProvider seam
(Available() + ServerEntries() []BrowseServer, SetBrowseProvider). BrowseServer is
a small local type the browser satisfies structurally (browser.Available()/
ServerEntries()), so SMB imports no browser package — the
[]browser.ServerEntry→[]smb.BrowseServer adapter is M8a compose wiring, alongside
SetDatagramConsumer/SetSessionConsumer. A potential browser → ERROR_REQ_NOT_ACCEP;
DOMAIN_ENUM mixed with other bits → ERROR_INVALID_FUNCTION; the reply packs
SERVER_INFO_1 records + comment heap. A TRANSACTION on a non-IPC$ tree, or with no
browser wired, answers STATUS_NOT_SUPPORTED / empty-success rather than dropping.
core/service/browser — gains the typed ServerEntries() []ServerEntry +
Available() accessors the SMB consumer needs (BrowseList() kept as a name-only
convenience over them).
lanman_test.go covers the browse-list reply, the potential-browser + domain-enum
gates, no-provider empty success, and the non-IPC$ refusal.
gofmt + vet clean, archtest green (uncached), default + -tags all builds pass,
full go test ./... green.

…PE\LANMAN Add the share-list RAP call (function 0x0000) over the same IPC$ \PIPE\LANMAN pipe as NetServerEnum2. Unlike the browse list, NetShareEnum is answered straight from SMB's own state — every bound disk share plus the virtual IPC$ pipe — with no browser involved. core/service/smb/lanman.go — the TRANSACTION dispatch now switches on the RAP function: NetServerEnum2 → browse list (browser), NetShareEnum → share list. handleNetShareEnum packs a SHARE_INFO_1 record (Name(13)+Pad(1)+Type(2)+ RemarkOff(4)=20) per share: each disk share as STYPE_DISKTREE with its Description() as the remark, then IPC$ as STYPE_IPC, with a trailing remark heap. core/service/smb/share.go — Share gains a Description() accessor over the held *share.Share, for the NetShareEnum remark. lanman_test.go — proves both records (PUBLIC + IPC$) with their names/types in the data block. So the IPC$ RAP layer now answers both queries a client makes: the inter-server browse list (NetServerEnum2) and the per-server share list (NetShareEnum). gofmt + vet clean, archtest green (uncached), default + -tags all builds pass, full go test ./... green.

The browser now broadcasts over IPX, not just NetBEUI. *IPXEngine gains emitDatagram and registers as a datagramEgress, so Service.SendDatagram fans the browser's HostAnnounce / election / backup-list traffic to NBF AND NBIPX at once. The NBIPX egress wraps the browser's SMB mailslot payload in an NMPI MailslotSend (opcode 0xFC), IPX type-20 broadcast on the NB-IPX datagram socket (0x0553), with the source/destination NetBIOS names in the NMPI header (a group destination maps to the workgroup name-type). Like the NBF egress it fans to the IPX broadcast node — the engine has no name→node binding for an out-of-band send. Re-home of the legacy service/netbios/over_ipx sendNMPIDatagram, stripped of the router import (the broadcast node + datagram socket are local consts). nbipx_test.go proves SendDatagram emits the NMPI MailslotSend with the names + payload round-tripped on the IPX wire. The browser is now transport-complete: it observes/announces/elects and serves its list over both NetBEUI and IPX. gofmt + vet clean, archtest green (uncached), default + -tags all builds pass, full go test ./... green.

…only browser frames Review correction: the browser should sit entirely on top of NetBIOS via a shared mailslot layer, with NO per-protocol and NO mailslot-envelope code. The per-NetBIOS-transport framing (NBF UI-frame / NBIPX NMPI-MailslotSend / NBT UDP-138) already lives correctly in core/service/netbios — that part stands. What was mis-layered: the M7d browser marshals/unmarshals the \MAILSLOT\* SMB_COM_TRANSACTION envelope itself, coupling it to a shared mailslot framing. Mailslots are a general second-class NetBIOS datagram-delivery mechanism with several consumers — \MAILSLOT\BROWSE (browser), \MAILSLOT\LANMAN (RAP datagram form), \MAILSLOT\MESSNGR (messenger / net send, a flagged future want), room for more (DirectPlay emulation). So the envelope is its own seam. New §3-quater: core/protocol/mailslot (the envelope codec, lifted out of protocol/browser) + a mailslot dispatch layer (Consumer registered by mailslot name + SendMailslot) that plugs into the NetBIOS DatagramConsumer/SendDatagram seams. Consumers (browser, future messenger) see/send only their own inner frame. Layering top-to-bottom: consumer frame → mailslot envelope → netbios.Datagram → per-transport wire framing. The IPC$ \PIPE\LANMAN RAP calls (session path) stay where they are (§3-ter) — distinct from the datagram-path mailslot announcements. §3-ter amended (browser holds neither transport nor mailslot-envelope code); package layout adds protocol/mailslot + service/mailslot + service/messenger (future). TODO: M7f (the reshape) + M7g (messenger) rows; M7d note records the correction. Code reshape is M7f (design-first, per request). No code changed here. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…ilslot layer Reshape (review correction): the browser must hold NO mailslot-envelope code and NO transport code. The \MAILSLOT\* SMB_COM_TRANSACTION envelope is a SHARED mailslot framing (browser, LANMAN, future \MAILSLOT\MESSNGR net-send, …), not browser-protocol — so it becomes its own seam (§3-quater). core/protocol/mailslot — the envelope codec (self-serialising Write DTO + NameBrowse/NameLANMAN/NameMessenger consts), lifted verbatim out of core/protocol/browser. The lift surfaced and fixed a latent bug: the data offset was a fixed 86, which overran for any mailslot name longer than \MAILSLOT\BROWSE (e.g. \MAILSLOT\MESSNGR); it now tracks the name length. core/service/mailslot — the dispatch layer: a Router that IS the NetBIOS DatagramConsumer (unwraps the envelope, routes the bare body by mailslot name, case-insensitive, to the registered Consumer) and exposes SendMailslot(name, src, dest, body, broadcast) (wraps + SendDatagram). core/service/browser — reworked: now a mailslot.Consumer (HandleMailslot, registered for \MAILSLOT\BROWSE) sending through a MailslotSink. It holds zero mailslot-envelope and zero transport code; MailslotTransaction is deleted from protocol/browser. The per-NetBIOS-transport wire framing (NBF UI-frame / NBIPX NMPI-MailslotSend) stays in core/service/netbios — that part of M7d/M7d-d stands. Layering top-to-bottom: browser frame → mailslot envelope → netbios.Datagram → per-transport wire framing. Each layer owns one concern; nothing reaches around another. A future \MAILSLOT\MESSNGR messenger (M7g) plugs into the same Router as a second consumer with no browser/SMB coupling. go list -deps ./core/service/netbios carries neither service/mailslot nor service/browser (acyclic). All four packages race-tested green; cs-tinygo blank-imports both new packages. gofmt + vet clean, archtest green (uncached), default + -tags all builds pass, full go test ./... green.

Second mailslot consumer (§3-quater), proving the seam is multi-consumer:
the browser and the messenger both register on the mailslot router and hold
zero envelope/transport code.
- core/protocol/messenger: the [MS-MSRP] single-block "net send"/WinPopup
frame codec (Message{From,To,Text}, type 0x01 + three NUL-terminated OEM
strings). No live capture exists, so per CLAUDE.md rule 6 the layout is
documented from [MS-MSRP] + the stable WinPopup form; parser tolerates a
missing trailing NUL.
- core/service/messenger: registers for \MAILSLOT\MESSNGR; on receive it
decodes, logs at Info, and publishes bus.MessageReceived on the new
bus.TopicMessage so the web UI can show net-send events. Send half
(Service.SendMessage) is the core a future cmd/csnetsend (T1) wraps.
- core/bus: TopicMessage + MessageReceived event.
- core/protocol/netbios: NameTypeMessenger (<03>).
cs-tinygo blank-imports both new packages; archtest green; go list -deps
./core/service/netbios carries neither messenger package (acyclic). gofmt/
vet clean, default + -tags all builds pass, full suite green (race-clean).

Add the authentication/user-store seam the design lacked. Both file services previously hardcoded guest; now identity is established at login and filters which shares are enumerable and bindable. core/auth: reflection-free contract (Authenticator, UserStore) plus a hand-rolled PBKDF2-HMAC-SHA256 credential codec (salt taken as a param; no crypto/rand or encoding/hex in core, both pull reflect). AuthSection carries backend+path only — never secrets. adapter/auth/local: smbpasswd-style file store (name:salt:hash:flags), atomic writes at 0600, case-insensitive. Lives in the adapter ring because salt generation needs crypto/rand. No build tag — always built. core/share: Permissions gains AllowedUsers (empty = guest/world); plumbed through fs.ShareSpec and share.Manager.Info. AFP: FPLogin parses the cleartext user/pass it previously dropped, validates via SetAuthenticator (nil/empty = guest), filters FPGetSrvrParms and gates FPOpenVol. SMB: SESSION_SETUP_ANDX parses the account name, validates cleartext (hashed accepted-as-guest), filters NetShareEnum/NetServerEnum2 and gates TREE_CONNECT. Restricted shares report as non-existent, not access-denied, to avoid a presence oracle. control.Plane gains Users/SetUser/SetUserDisabled/RemoveUser backed by an optional control.UserAdmin (nil store -> ErrUnavailable), satisfied by the supervisor — the surface the web UI Users panel will bind to.

…ue fix The TOML/UCI codecs and file/UCI stores were already built (B6/D4/D6); this slice adds the missing real-section round-trip coverage and fixes a latent codec bug it surfaced. The M8a Auth section now round-trips through both codecs, plus an end-to-end codec -> file.Store -> codec persistence test (the path the control plane's config-apply drives), proving the store selector a user writes is what auth.SectionFromModel reads back. Fix: the UCI tokenizer dropped an empty quoted value (option key ''), so an option whose string field is unset parsed to too few tokens and failed the whole Unmarshal. A default config.Model — whose well-known Logging.Level is "" — could therefore not be reloaded through UCI; only models that set every string field round-tripped. The tokenizer now emits an empty token when a quote was opened. TOML was unaffected. Documented in spec/errata.md "UCI empty-quoted-value tokenizer".

…uild
Diagnosed with tinygo installed locally. Each layer was a separate, real bug —
fixed the ones that were genuinely fixable, and traced the remaining WT32-ETH01
blocker to its actual root cause rather than patching around it.
Fixed:
- hardware/esp32/wt32eth01/{emac,wifi}.go declared `package wt32eth01` while
main.go/cts.go in the same directory are `package main` and call OpenEMAC/
NewWiFi unqualified — a plain package-name typo that made the directory
uncompilable as one package.
- scripts/build_wt32eth01.sh used `-target=esp32`, which TinyGo treats as
inheritable-only (a base other board targets extend, not directly buildable),
and never passed `-tags wt32eth01`, which every file in that package requires
(`//go:build esp32 && wt32eth01`) — switched to `-target=esp32-generic
-tags wt32eth01`.
- hardware/peripherals/sdcard imported tinygo.org/x/drivers/fatfs, which does
not exist in any released version of that module; the only real TinyGo FAT
filesystem found (tinygo.org/x/tinyfs/fatfs) is a cgo binding, and cgo is not
usable on TinyGo's baremetal ESP32/RP2040 targets. Disabled the import in
both hardware/esp32/wt32eth01/main.go and hardware/pico/main.go with a note
on why, rather than leave it silently broken.
- hardware/peripherals/w5500 (Pico's wired-Ethernet option) was missing its
go.mod entry for tinygo.org/x/drivers — added.
- core/fs's diskUsage and core/hostinfo's PrimaryInterface/InterfaceForDevice/
HardwareAddrForDevice used real syscall.Statfs / net.Interface.Addrs() /
net.InterfaceByName, none of which TinyGo's baremetal syscall/net implement.
core/fs already had the right fallback pattern (diskusage_other.go, "0/0
unknown") for this exact class of gap — TinyGo just wasn't routed into it
because these targets report GOOS=linux, matching the real-Unix build tag.
Added `&& !tinygo` / `|| tinygo` to route it correctly, and split
core/hostinfo/primary.go the same way (new primary_interfaces.go +
primary_interfaces_tinygo.go) rather than leave the whole package
uncompilable for embedded targets.
Not fixed — real root cause identified, out of scope for a targeted fix:
hardware/esp32/wt32eth01/{emac,wifi}.go bind directly against ESP-IDF's C API
(`#include <esp_eth.h>`, `<esp_wifi.h>`, `#cgo LDFLAGS: -lesp_eth`), which needs
the full ESP-IDF SDK toolchain present at build time — CI only installs Go +
TinyGo, no ESP-IDF, so this was never going to link there. More broadly, both
hardware/esp32/wt32eth01 and hardware/pico import the FULL desktop compose/
registry + compose/runtime + adapter/control/http stack (pcap-adjacent
golang.org/x/net internals, TOML file config, a web UI) — architecturally much
wider than cmd/cs-tinygo, this project's own deliberately-narrow "TinyGo-safe
core subset" that the passing "TinyGo amd64 gates" CI job actually builds.
Getting a real board target green needs curating a minimal embedded import
surface (closer to cmd/cs-tinygo's), which is a scope/architecture decision,
not a bug fix.
Verified: full `go build`/`go vet`/`gofmt`/`go test` (all tags) unaffected;
scripts/ci/tinygo-gate.sh (the actual passing CI check) still green.

…ient shape The previous version described the pre-refactor runtime topology almost verbatim (a known gap flagged in PR #20's description) — barely touched since before the hexagonal rewrite despite the whole runtime changing underneath it. Rewritten to cover: - The five rings (core/adapter/compose/client/cmd) and the dependency rule that holds them apart, with a mermaid diagram. - Rationale: why core/ is import-restricted (archtest's actual forbidden list), what that buys in practice (testability, one-command-core/N-transports, real embedded targets, config/protocol separation), and why compose/ and client/ are their own rings rather than living under cmd/ and adapter/. - A full directory map (core/, adapter/, compose/, client/, cmd/) with a one-line role for every subpackage. - Runtime composition (config -> registry -> cross-wire -> supervisor) and a concrete data-flow walkthrough (an AFP read over EtherTalk vs. over DSI), both as mermaid diagrams. - A new client-architecture section: the client/afp.Session interface as the client-side mirror of the server's CommandHandler/CommandCircuit split, the redial-as-injected-closure reconnect design, and why the fork backend differs by scheme — none of this was in the doc before. - Control-plane/web-UI split (brief; full depth stays in docs/web-ui.md). - Embedded targets: cmd/cs-tinygo (the real, passing, narrow core subset) vs. hardware/{esp32,pico} (the full desktop stack, not yet green) and the established !tinygo/tinygo split pattern for OS-API gaps. - Testing structure overview. - A "how to expand" section with concrete recipes (new port, new DDP service, new session transport, new fs backend, new client scheme, new control front-end, new config section), each pointing at a real existing example.

…s embedded fix) diskusage_other.go's tag gained an `|| tinygo` clause so TinyGo baremetal targets route to the 0/0 stub regardless of reported GOOS. diskusage_windows.go still had a bare `windows` tag with no `!tinygo` exclusion, so a GOOS=windows TinyGo build (scripts/ci/tinygo-gate.sh's windows-amd64 gate) now matched BOTH files and failed with "diskUsage redeclared in this block" — caught by the actual CI gate right after the previous commit landed. Same `&& !tinygo` treatment as diskusage_unix.go already got; verified via `GOOS=windows GOARCH=amd64 tinygo build` locally. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
… Script type mismatch
- .github/workflows/{pr-ci,release-main}.yml pinned tinygo-version "0.41.0", which
cannot assemble a goroot from the Go 1.26 stdlib the runner resolves to ("package
internal/strconv is not in std") — refactor-harness.yml's TinyGo amd64 gates job
already carries this exact fix+errata comment; the other two workflows were never
updated to match. Confirmed via this PR's own "Build Embedded (TinyGo)" job.
- packaging/windows/ClassicStack.iss: ResolveVolumesPlaceholder failed to compile
("Type mismatch") because LoadStringFromFile's second parameter is `var S:
AnsiString`, a by-reference parameter that requires an exact type match, while
Contents was declared as the default Unicode `string`. Load into a dedicated
AnsiString and convert, per Inno Setup's Pascal Script rules for
LoadStringFromFile/SaveStringToFile.
The .iss fix is reasoned from the Pascal Script signatures, not locally compiled —
no Windows/ISCC toolchain available here. Will confirm against the next CI run
rather than claim it's verified.

…-lint)
pr-ci.yml's Quality job had never actually completed a run against this tree
before this PR (always blocked earlier by the race-enabled tests step failing
first), so this lint debt had never surfaced. Ran `golangci-lint run --fix`
(errorlint, govet, misspell all fully auto-fixable) then fixed the fallout:
the errorlint autofix rewrites `err == sentinel` / `err.(type)` to
`errors.Is`/`errors.As` but does not always add the `errors` import, which
broke the build across ~40 files. Iterated `go build`/`vet`/`test -run=^$`
until clean, then goimports to settle import grouping.
Every rewritten comparison is a genuine correctness fix, not just style: a
plain `==`/type-assertion against a sentinel error silently stops matching the
moment that error is wrapped anywhere in its call chain, so these were latent
bugs waiting for the next `fmt.Errorf("...: %w", err)` to be added upstream of
one of them.
Verified: `go build`/`go vet` clean (bare and -tags all), full `go test -tags
all ./...` passes, core/internal/archtest still green (errors is stdlib, nowhere
near the forbidden-import list).
Remaining lint categories (errcheck, gocritic, ineffassign, revive, staticcheck,
unused — 136 findings) are not auto-fixable and are being worked through
separately.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
staticcheck (real fixes):
- adapter/dsi/dsi_test.go: don't pass a nil context to Stop; use context.Background().
- adapter/link/tashtalk/tashtalk.go: the empty writeMu Lock/Unlock is an intentional
"wait for the mutex to be free" barrier, not a bug — annotated and suppressed
(SA2001 has no way to know the point is the pairing itself).
- client/afp/afp.go: removed a genuinely no-op nested `if dead != nil {}` branch left
over from a prior refactor, folding its comment into the surrounding logic instead.
- client/xfer/xfer_test.go: the empty error-ignoring branch in readAll was silently
swallowing any non-EOF ReadAt error, not just EOF as the comment claimed — now
actually asserts errors.Is(err, io.EOF) and fails the test otherwise.
- core/service/ncp/namespace_test.go: removed a dead first assignment to `root`
that was unconditionally overwritten before use.
- cmd/csmount/main.go, cmd/internal/cli/cli.go: two SA4023 "always true" findings
are artifacts of golangci-lint's build-tags config (just `all`, no `fuse`/`cgo`),
which only ever analyzes the FUSE-not-compiled-in stub of mountAt (genuinely
always errors, by design) and relaunchProcess (whose only success path calls
os.Exit and never returns, which staticcheck doesn't model) — both are correct
behavior, not bugs; suppressed with comments explaining why.
unused: removed confirmed-dead code (verified via whole-repo grep, not just the
default lint build tags) — adapter/control/finder's serviceAllowed/parentRef,
client/etherdfs's ethHdrLen, client/smb's errIPXNoMAC and a test-only firstWrite
helper, core/service/ncp's appendLE16, core/service/afp's routedControls test
helper, an unused parseCodec.data test field, and three superseded copyDir/
copyFile/copyFork wrappers in client/xfer (the real entry points call their *Ctx
siblings directly; moved the doc comments onto those instead of losing them).
client/fuse's onInit field looked identically unused but is NOT dead — it's set
and called by host.go, which needs the real fuse&&cgo tags to compile, so
golangci-lint's tagless view never sees the use; suppressed instead of deleted.
revive (package-comments, all mechanical): several files had a file-specific doc
comment sitting directly attached to `package X` with no blank line, which Go/
revive read as an attempt at THE package comment and rejected for not starting
with "Package X ..." — detached them (blank line) where a real package doc
already lives elsewhere (core/fs, core/router, core/protocol/smb all have one in
another file). core/buf/buf.go's real "Package buf ..." comment had a //go:build
line wedged between it and `package buf`, breaking the attachment — reordered
(build tag, blank line, doc comment, package). core/service/netboot/netboot.go's
SPDX header and its real package doc were one un-blank-separated block, so revive
saw "SPDX-..." as the start instead of "Package netboot" — separated them.
core/hostinfo had no package comment anywhere in the package — added one to
hostinfo.go (the one file with no OS build tag). adapter/macgarden's real
package-level description lived in fs.go under a plain "This file implements..."
opener — reworded to "Package macgarden ..." since, same as client/fuse above,
its only OTHER package-doc candidate (stub.go) is built under the tags NOT
compiled together with fs.go, so it was never actually the canonical one lint
saw.
Verified: go build/vet clean (bare and -tags all), full go test -tags all ./...
passes.
Remaining: errcheck (73), gocritic (26), ineffassign (5) — being worked through
separately.

All five were genuine dead writes, not stylistic nitpicks: - adapter/config/describe/describe.go: `cap := embedCap` was unconditionally overwritten by both branches of the very next if/else — embedCap itself is still used elsewhere in the function (the non-anonymous-embed field case), just not here. - core/service/afp/catsearch.go, parms_test.go: a final `off += N` past the last read of `off` in each function — dead trailing increments. - core/service/afp/filedir.go: `newStore := srcStore` was unconditionally overwritten by both branches of the following if/else; `newStore` itself is used further down (Stat/renamePath), just not at that initial value. - core/service/afp/handlers.go: `out = putPString(...)` — putPString's write into b's backing array (via append) is real and needed, but the returned slice header was being thrown away one line later by `out = b[:machineOff]` anyway; call it for the side effect instead of assigning its result. Verified: go build/vet clean, full go test -tags all ./... passes, ineffassign now reports 0. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Resolves the last gocritic categories: unlambda (collapse trivial closures to direct function references, e.g. reg_localtalk.go's ltoudp/tashtalk vars and the finder test helpers), appendAssign (reassign append results to the same variable rather than a fresh one, notably a real bug fix in smb.AppendNameTrailer which was discarding the appended destination bytes; the frag-buffer append sites in the netbios/smb packages are nolint'd since frag is nilled immediately after and the aliasing is harmless), deprecatedComment and mapKey (foldresolve.go, fileio.go), and exitAfterDefer in the three standalone probe commands (csecho/csipxping/csncpinfo) and cli.go's relaunchProcess path, each given an explicit Close/cleanup call before os.Exit with a nolint explaining why the skipped defer is harmless. Also runs gofmt over two files with pre-existing formatting drift (ref.go, progress.go) found while verifying this batch. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Wraps every flagged deferred Close (files, connections, sessions,
zip readers, response bodies, mDNS/UBus/SQLite handles) as
defer func() { _ = x.Close() }() and prefixes the flagged
fmt.Fprintf/Fprintln calls (CLI/interface-listing output, SSE
event writes, debug trace) with _, _ = , matching this repo's
established house style for intentionally-unchecked errors.
This clears the last golangci-lint category (errcheck, 70
findings); `golangci-lint run --max-same-issues=0
--max-issues-per-linter=0` now reports 0 issues across every
enabled linter (errcheck, errorlint, gocritic, govet, ineffassign,
misspell, revive, staticcheck, unused).
Verified with go build/vet -tags all, gofmt -l, go test -tags all
./... and go test -tags all -race ./... all clean.

golangci-lint's local darwin runs never see these _linux.go files
(GOOS-gated), so the three unchecked defer f.Close() calls in
diagnostics_linux.go and gateway_linux.go only surfaced once CI ran
the lint step on ubuntu-latest. Same defer func() { _ = f.Close() }()
pattern as the rest of the errcheck cleanup.

release-main.yml previously also ran on every push to main, auto- cutting a "dev-<sha>" prerelease each time -- noisy, and not what a 1.0-RC cycle needs (we want to publish v1.0.0-rc1, -rc2, etc. as distinct, deliberate releases). Two changes: - The workflow trigger drops `push: branches: [main]`, keeping only `tags: ['v*']` and `workflow_dispatch`. - compute-release-metadata.sh's non-tag fallback (which synthesized the dev prerelease) is replaced with a hard failure: it now only ever accepts a ref_type of "tag" matching vMAJOR.MINOR.PATCH or vMAJOR.MINOR.PATCH-rc / -rcN. This also fails a workflow_dispatch run picked from a branch, so a release genuinely cannot be cut without a real tag. - The regex gains the optional -rc suffix; prerelease is "true" for any -rc tag and "false" for a bare vMAJOR.MINOR.PATCH tag, and build_version carries the suffix through (e.g. "1.0.0-rc1"). PR CI's per-run build artifacts (Windows installer, etc.) are unaffected -- those are workflow artifacts uploaded on every PR run, not GitHub Releases, and don't need a tag.

…eleases
hardware/esp32/wt32eth01/{emac,wifi}.go cgo directly against ESP-IDF's C
headers and component libraries, so TinyGo can't compile them without the
SDK on disk. Adds espressif/install-esp-idf-action (v5.3) to both
pr-ci.yml and release-main.yml's embedded jobs, and wires the resulting
IDF_PATH into CGO_CFLAGS (scripts/build_wt32eth01.sh) so the include
search covers the ESP-IDF components these files touch.
This is a best-effort step, not a full fix, and is documented as such:
ESP-IDF's headers still expect a project-generated sdkconfig.h and the
-lesp_eth/-lesp_wifi/... component libraries only exist after a real
`idf.py build` of a matching component project -- neither exists here.
Both are called out in scripts/build_wt32eth01.sh as the remaining gap
for follow-up work.
Also fixes something more consequential found while looking at this:
"Build WT32-ETH01" ran FIRST in both jobs' step lists, so its failure
was aborting the job before the Pico builds (which build clean) ever
ran -- and in release-main.yml, build-embedded is a hard dependency of
the release job, so no release could ever publish while WT32-ETH01 was
red. Reordered Pico builds first, marked the ESP-IDF install and
WT32-ETH01 build steps continue-on-error, and split release packaging
so a missing wt32eth01.bin only skips that one artifact (with a
build warning) instead of failing the whole job.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
"Build Pico" was masked by "Build WT32-ETH01" always failing first (see
the previous commit) and had never actually been exercised in CI. With
Pico running first, it turned out none of the four variants compiled.
Fixed, in the order hit:
- golang.org/x/net/ipv4 (multicast UDP, via mdns and LToUDP browsing)
and client/netbios's NBNS lookup both need net.ListenUDP /
net.Interface.Addrs(), which TinyGo's baremetal targets don't
implement. Split client/afp/mdns.go, client/link/localtalk.go, and
client/netbios/nbns.go into !tinygo (real) / tinygo (stub, returns a
clear "not supported" error) pairs, matching the existing
core/hostinfo/primary_interfaces*.go precedent. client/browse/tcp.go's
net.InterfaceByName fallback got the same treatment
(ipv4_fallback*.go). nbns_unix.go's tag gained "&& !tinygo" since
TinyGo's baremetal GOOS reports linux, so the bare "unix" tag matched
it too and pulled in a termios syscall it doesn't implement either.
- adapter/serial (github.com/jacobsa/go-serial) shells out to termios
ioctls TinyGo doesn't implement. Split into config.go (plain data,
shared), serial.go (!tinygo, the real Open), serial_tinygo.go (stub).
- hardware/peripherals/lan8720a/lan8720a.go: a real bug, unrelated to
TinyGo -- id2 (half of the PHY ID read) was read and never checked,
which is also what made it a compile error (declared and not used).
- hardware/peripherals/w5500/w5500.go: written against a MACRAW raw-
frame socket API (OpenMACRAW/GetRxSize/per-socket Read/Write/Send)
that tinygo.org/x/drivers/w5500 v0.35.0 (the actual pinned dependency)
does not have -- it only exposes the chip's IP-socket offload, not a
raw-frame passthrough. Replaced with a stub that fails cleanly
(ErrNotImplemented) instead of not compiling; bridging our
link.FrameLink onto that API is real follow-up work, not attempted
here.
- hardware/pico/main.go: `*lan8720a.Device` was never a real type
(lan8720a.New returns *Driver) -- another compile error masked by
WT32-ETH01 failing first.
- hardware/pico/ethernet_w5500.go: `&machine.SPI1` -- SPI1 is already
`*machine.SPI` on this target, so this took the address of a pointer.
- hardware/peripherals/cyw43439/cyw43439.go (Pico W / Pico 2 W):
tinygo.org/x/drivers/net and .../net/cyw43439 don't exist in any
released tinygo.org/x/drivers version. Same treatment as w5500 --
stubbed to fail cleanly, mirroring the sdcard/fatfs gap already
documented in hardware/pico/main.go.
- scripts/build_pico.sh: TinyGo 0.41.1 has no "pico3" target (RP2350's
target is "pico2"); fixed both the pico2 and pico2w cases. TinyGo's
own -target=pico2 supplies a "pico2" build tag, not "pico", so
hardware/pico's shared files (previously `//go:build pico`) are now
`//go:build pico || pico2` so they compile under both chips without
forcing an extra -tags that would collide with TinyGo's own internal
per-chip machine-package files (confirmed: passing "pico" alongside
"pico2" causes TinyGo's board_pico.go and board_pico2.go to both
compile, redeclaring the same symbols).
All four `bash scripts/build_pico.sh {pico,picow,pico2,pico2w}` variants
now build clean via TinyGo 0.41.1, verified locally. Desktop build/vet/
test/lint (go build/vet -tags all, go test -tags all ./..., golangci-lint
--max-same-issues=0 --max-issues-per-linter=0) all still clean too.

Failure observed: "gap between write 1 and 2 = 17.254149ms, want ≥ ~20ms" -- a real but rare flake, not a pacer bug. paceLink.Write schedules each node's next send against an absolute target time (now + wait + gap, computed once per write), so ordinary scheduler jitter can only push a measured gap LATER, never earlier, under time.Sleep's documented "at least the duration" guarantee; confirmed this by re-deriving the schedule algebraically and by 100+ local runs (including under synthetic CPU load and -race) that never reproduced it. The test's own tolerance was just too tight for a loaded/ virtualized CI runner: a flat 2ms against a 20ms target (10%) is easily exceeded by ordinary timer/scheduling jitter. Widened both the per-pair gap check and the aggregate elapsed check to a proportional 25% tolerance (gap/4 = 5ms here) instead of a flat 2ms / zero tolerance, so the test still meaningfully catches "pacing isn't happening at all" (near-zero gaps) without flaking on jitter within a normal range.

Runtime.Start attaches and seeds each [Router].members port synchronously right after StartAll returns, but a real EtherTalk/LToUDP/TashTalk port's node-address claim (AARP/LLAP) finishes in a background goroutine and Start never waits for it. When the claim lands after Attach already ran with NetworkMin()==0, router.Attach's own nonzero guard skips installing the directly-connected route and seedZone's zero-range guard skips the ZIT too — and nothing ever retried either install. The port still announces its claimed range correctly over RTMP and answers same-network traffic fine (Inbound's same-network fast path needs no routing-table entry), but any service reply that must round-trip through router.Reply->Route (ZIP's ATP zone queries, AFP's ASP session reads) does RoutingTable.GetByNetwork and gets a silent, permanent nil — the reply is dropped with no error, forever. This reproduced as: Chooser showing only the AFP server's own zone via GetLocalZones (expected) but never all zones via GetZoneList, and AFP connections stalling on ASP GetStatus with zero replies. Poll briefly (bounded, cancelled on Stop) for a late claim after Attach and re-run the same route/zone install once it lands; both installs are idempotent so this is a no-op on the fast path where the claim already beat Attach.

handleBrRq resolved a zone=* request to the rx port's single zone (routeZone) to pick routing targets, but buildCommonPayload was still called with the original unresolved `zone` — so the re-broadcast LkUp still carried a literal "*" in its tuple. Real NBP responders on other member networks echo that back verbatim, so their replies never match a zone-scoped Chooser/Finder query, which is why Finder only listed servers on the querier's own network segment (multiple AFP servers being invisible in the Chooser despite csclient's NBP discovery finding them all).

dhcp_relay=true always sources client addresses via real DHCP relay (adapter/macipgw/macipgw.go, core/service/macip/macip.go assigner()), regardless of `mode`. Combined with mode='nat' it silently bypassed the 192.168.100.0/24 static pool, handing out addresses from the relayed DHCP server instead. Per server.toml.example, dhcp_relay is meant to pair only with bridge mode. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
nat mode + dhcp_relay=true previously silently relayed real DHCP onto the IP-side network instead of using the NAT static pool, handing MacIP clients addresses outside the configured 192.168.100.0/24 range with no indication anything was wrong. Enforce the invariant at the actual point of use (Egress.New), so it holds regardless of how the Config was assembled: when both flags are set, log a warning and clear DHCPRelay before it's consulted anywhere else in New (natOnly, the DHCP client, the BPF filter). Covered by TestNewNATModeForcesDHCPRelayOff. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
handleOpenAndX handed out a FID over os.OpenFile(dir) without checking IsDir first, unlike OPEN/CREATE. The open itself succeeded (attrs correctly reported Directory), so a directory-copy client only found out on the follow-up READ, which failed with the generic statusUnsuccessful (ERRSRV/ERRerror) — a code CORE-dialect clients can't act on, so the whole copy aborted (seen client-side as Windows "System error 1026" against an IPX SMB share). Reject with STATUS_FILE_IS_A_DIRECTORY at open time instead, matching handleOpen/handleCreate/handleNTCreateAndX.
…ports router.Inbound() unconditionally backfilled a zero source network from the rx port. That's correct for a short-header LocalTalk-style port (a zero network there just means "this segment"), but on an extended port (EtherTalk, LToUDP) a zero source network means the sender is still in AARP startup range with no claimed address at all — exactly the case ClassicStack's own probe clients (client/link.NewOpener, used by both csclient and the web UI's AFP discovery) intentionally produce rather than running a full AARP claim. Backfilling it there manufactured a network.node nothing owns and erased the signal Reply() needs to broadcast instead of unicast, so ZIP/NBP/etc. replies silently vanished into an unresolvable AARP target. NBP had the same bug independently: handlePacket defaulted a zero NBP-tuple network to from.Network() unconditionally, and replyMatches always unicast via Route() rather than ever using Reply()'s broadcast path, so even after the router fix NBP still fabricated an address. Net effect: an unnumbered client's NBP/ZIP queries over EtherTalk/pcap got no replies at all (confirmed via packet capture — ClassicStack's router never answered a GetZoneList or BrRq from such a client, while the same queries over LToUDP worked only because LToUDP unicast is a multicast-to-everyone no-op on addressing).

…s contents
resolveSearchPath special-cased a non-wildcard last path element that named
a directory by listing that directory's own children, instead of matching
the name against its parent like every other exact-name lookup. [MS-CIFS]
§2.2.6.2 describes FIND_FIRST2 as a search "within a directory or for a
directory" — a bare "\DRIVER" asks whether an entry named DRIVER exists,
answered with that one entry (Directory attrs set), confirmed against a
real Windows 98 server in spec/captures/nwlink-win98.pcap frames 182-183.
A directory-copy client relies on exactly this to tell files from
directories without opening them first. Getting the child listing instead
meant it never saw the entry it asked about, then failed trying to open the
directory directly ("Cannot find the specified path") once OPEN_ANDX
correctly started rejecting directories.
ReservedSet.unescape restored every "0xNN" store token to its raw rune
unconditionally, regardless of which wire the name was headed for. Control
characters are always-reserved (every backend escapes them on the way in,
independent of ReservedPOSIX/ReservedNTFS), so a classic Mac "Icon\r"
custom-icon marker — its name is literally "Icon" plus a raw CR byte —
round-trips through the store as "Icon0x0D" and then, on the way back out,
got the raw CR restored on EVERY wire, AFP and SMB alike.
That's correct for AFP's Mac clients (WireMacRoman/WireUTF8): a raw CR in a
filename is normal on HFS and they handle it natively. It's wrong for
SMB/NCP's DOS and Windows clients (WireANSI/WireUTF16): Win32 filenames can
never contain a control character under any encoding. A real capture showed
Explorer refusing to copy the file ("The filename you specified is invalid
or too long"), and NT 3.51 File Manager crashing just listing the share.
unescape now takes the destination WireEncoding and leaves a token for a
windowsIllegal rune (control chars, plus the NTFS/FAT reserved punctuation)
as literal "0xNN" text when dst is WireANSI/WireUTF16 — which happens to
already be a stable, round-trippable name, since it's exactly what's on
disk when the backend needed to escape the character for storage too.
SMB clients are always DOS/Windows redirectors, but a share's storage
escaping previously defaulted (with every other protocol) to
ReservedPOSIX — only escaping what the POSIX store itself can't hold. A
Mac-originated name containing an NTFS/FAT-reserved character (';?*<>:"|\'
— all legal on HFS) would sit raw in storage and flow straight to an SMB
client unescaped, a byte Windows could never have created locally.
Add "windows-safe" (NewWindowsSafeFilenameCodec): identical to "identity"
but with ReservedNTFS in place of ReservedPOSIX, so those characters are
escaped in storage the moment a name is written, not just filtered when
read back. ShareSection.fsSpec now defaults an unset FilenameCodec to
"windows-safe" instead of falling through to fs.withDefaults' generic
"identity". Complements, not replaces, the prior Encode-time DOS-wire
unescape guard: that guard is what stops an already-escaped control
character (always-reserved under either set, e.g. a classic Mac "Icon\r"
marker's raw CR) from being restored onto the wire regardless of which
codec a share is on; defaulting SMB to windows-safe additionally escapes
the wider NTFS punctuation set at write time.
…ar state - adapter/link/framing/aarp: trim Ethernet zero-padding using the 802.3 length field before ddp.Decode, which rejects anything past the DDP header's declared length. Short DDP payloads (ATP TReq, ZIP/ASP GetZoneList/GetNetInfo/GetStatus) are always padded on a real NIC and were silently dropped as ErrBadLength, while longer packets (NBP, most AEP) happened to clear the padding and decoded fine — this is why ZIP/ASP looked dead while NBP/AEP worked. Mirrors framing.go's existing plain-framer trim. - compose/supervisor + cmd/internal/cli: a component whose Stop doesn't select on ctx could hang StopAll past its deadline, and a second Ctrl-C/SIGTERM during that hang was silently dropped (NotifyContext's handler goroutine only reads one signal). stopWithDeadline abandons a component that misses its deadline instead of blocking the rest of teardown; a second interrupt now forces immediate exit. - adapter/control/finder/local.go + go-finder-host.ts: LocalVolumes now returns [] instead of nil (GET /finder/local feeds an array spread in the web UI). The web UI's sidebar also now tracks [Client] enablement live via the state SSE topic, hiding a scheme's group when its service is disabled instead of only reflecting it after a reload. Excludes server.toml (local test-rig device paths/zone, not a code change) and the runtime-overwritten *.pcap capture files.
Builds the Win32 (native MSVC 1.2) and Win16 (MSVC 1.5 via otvdm) SMB test clients on windows-latest, and the macOS AFP test client via the official Retro68 Docker image on ubuntu-latest, publishing each disk image (SMBE2E1.img x2, AFPE2E.dsk) as a workflow artifact.

Retro68's default "multiversal" interfaces don't implement pre-System-7 APIs like AppleTalk.h yet, which the AFP e2e client needs. Vendor MPW-GM.img.bin (Apple's real Universal Interfaces, MacBinary DiskCopy image) under tools/end-to-end/tools/mpw/ alongside the pinned MSVC kits, and point the Retro68 container at it via INTERFACES=universal + INTERFACESFILE.

NewWindowsSafeFilenameCodec (SMB's new default) reused ReservedNTFS, which escapes '*' and '?' along with the genuinely-always-illegal Win32 punctuation. Those two are also FIND_FIRST2/SMB_COM_SEARCH wildcard metacharacters on the wire, and a search pattern is decoded through the same per-element codec.Decode as any other path text — resolveSearchPath's wildcard/pattern split (trans2.go) runs on the string Decode already produced. So every "*" pattern decoded to the inert token "0x2A" before the split ever saw a wildcard, and resolveSearchPath treated it as an exact-name lookup for a file literally called "0x2A" — no share has one, so every FIND_FIRST2 came back status-success with zero entries. SMB clients saw a share with no files at all. Add ReservedSMBWire (ReservedNTFS minus '*'/'?') and use it for windows-safe instead. ReservedNTFS itself is untouched — that set is about what an actual NTFS disk can hold, not about parsing a request, so it still escapes both. Regression tests at both layers: TestWindowsSafeCodecLeavesWildcardsAlone (codec-level) and TestTrans2_FindFirst2WildcardWorksOnWindowsSafeCodec (end-to-end through the real share-build path, not the synthetic "identity" fixture every other trans2 test uses — which is exactly why this one slipped past the test suite the first time).

Summary
This merges the
feature/refactorbranch: a ground-up rewrite of ClassicStack onto ahexagonal (
core/adapter/compose) architecture, plus everything built on top ofit since the rewrite landed. It replaces the old
internal/app,port/,protocol/,service/,router/,pkg/,netlog,capture/,config/tree entirely.253 commits, 2173 files changed (+393,924 / -64,367). Latest tag on
mainisv0.3.0;this is proposed as 1.0.0-RC.
.refactor/00-DESIGN.md,ARCHITECTURE.md):core/holdsprotocol-pure logic with zero I/O imports (enforced by an import-graph CI gate —
reflect,net,encoding/binary,encoding/jsonetc. are all forbidden incore/,which is what keeps a TinyGo/embedded build possible);
adapter/holds the concreteI/O (pcap, sqlite, http, uci, serial, dsi, smbtcp);
compose/wires componentstogether via a registry + supervisor with dependency-ordered start/stop.
strangler migration, milestones A–D, M1–M11, cutover) — see

(deleting the legacy runtime, repointing binaries at the new run-core) landed
2026-06-18 (
21f8d1b,511299a); everything since is feature work on the newarchitecture, not migration.

Compatibility notes
[Bridge]is now theonly source for backend/device/MAC/frame mode (see
ARCHITECTURE.md). Existingserver.tomlfiles fromv0.3.0will need migration — there is no automatedupgrade path in this PR.
git submodule update --init --recursive(
third_party/classicstack-web). CI andREADME.mdare already updated for this.cmd/classicstacknow boots throughcmd/internal/cli→ the composeruntime instead of
internal/app. Flags/behavior should be equivalent per.refactor/TODO.mdM9/M10, but this is the highest-risk surface for regressionssince it's the main entry point everyone runs.
Known gaps / follow-ups (not blocking, but worth tracking post-merge)
ARCHITECTURE.mdstill describes the pre-refactor runtime topology almost verbatim(only one line changed vs.
main) — it doesn't yet describe the core/adapter/composerings, the registry/supervisor model, or the new cmd/internal/cli entry point. Worth
a follow-up doc pass.
.refactor/TODO.md, a handful of milestones are still open:M8a(share config →share.Managerwiring for AFP/SMB volumes),M8-spa(new-ring SPA, explicitlydeferred/held),
M11opener-dispatch follow-ons. None of these block a build, butthey're real scope not yet closed out.
scripts/ci/compute-release-metadata.sh's tag regex only accepts strictvMAJOR.MINOR.PATCH— av1.0.0-rc1tag will fail CI's release job. If you want anactual pre-release tag (not just merging to
main, which auto-cuts adev-<sha>prerelease), that script needs a pre-release-suffix case first.
CI
Refactor Harness CIis green on the current head (75db6b8, run32545567182).
Note this PR will run under
pr-ci.ymlonce opened againstmain, which hasn'texercised this tree before — worth watching the first run closely.
Heads-up: merging this triggers a release
release-main.ymlruns on every push tomainand publishes a GitHub Release(
dev-<sha>, marked prerelease) automatically — merging this PR will cut a releasebuild across all platform/variant matrix targets. Flagging this explicitly since it's
not something a normal PR merge does in most repos.
