In a slide-show format. Covers all of the \"Ages\" in the game Myst. You can opt to install one or more or all of the modules. This was a give-away promotion. The source of this installer was from MacFormat magazine issue 40, August 1996 CD.\n\nMD5 checksum: 54e17afffb1f755f4dc19f39ef717483 *mystscreensaver.sit\n\nMyst_Screen_Saver-hybrid_CD.iso is a hybrid Mac/PC installer disc image sourced from the Internet Archive.\n\nMyst_screensaver_images.zip includes the 249 JPEG files that are installed as part of the screen saver.\n\nRuns on a 68020 CPU, Mac OS 7.0 or newer. Does not run on Mac OS 9. - I wouldn't attempt it even on 8.0 or newer without updating the After Dark Engine vers. 3.0 that this installs 1st. You are probably safe to use this as is with a Mac OS from vers. 7.0 to 7.6.1\n\nNot native PPC but will run on PPC OK given the right conditions.\n\nNote: If you opt for the full install or install the Selenitic Tour module individually, the installer claims the image \"Selene20.JPG may be damaged, use with caution\", It can be safely deleted (there are over 200 images in total, you won't miss one less).\n\n[Warning:] The After Dark Engine that gets installed is version 3.0b - I think the \"b\" stands for buggy. In the installation process it creates on Basilisk II (perhaps other Macs too), a corrupt Preferences file in the System Folder's Preferences Folder in its own \"After Dark Preferences\" folder. What happens is; after installing you need to reboot your Mac. After booting up, After Dark immediately starts and locks you out of your computer. It asks for a nonexistent password (not the provided installation password) and you have no option but to crash your Mac and start up with Extensions turned off.\n\nThe Workaround:\n[a] Replace the installed corrupt Preferences with the supplied working After Dark Preferences file from the above 2nd Download link on this page, named \"a-dark-3-prefs.sit\". Better: Preempt the corrupt Prefs file before you install the screen saver by extracting the After Dark Prefs folder from the \"a-dark-3-prefs.sit\" file and placing this folder inside of your System Folder's Preferences folder.\n[b] Alternatively; Install the After Dark 4.0 (Engine) from here at the Macintosh Garden. And only install the Myst Saver Modules by choosing only the modules that you want to Install. That is, don't choose a Full Install or elect to install the After Dark Engine 3 from the Myst Screen Saver Installer. This would give better compatibility with newer Mac OS's too.", + "Downloads": [ + { + "Title": "mystscreensaver.sit", + "Size": "24.44 MB", + "OS": "For\n\t\t\t\t\t\t\t\t\t\t\t\t\t\tSystem 7.0 - 7.6", + "Links": [ + { + "Text": "www", + "URL": "http://download.macintoshgarden.org/apps/mystscreensaver.sit?expires=1776922480\u0026token=ISNFjOjmLIMn_L_IT0nwNA\u0026st=17b538827ab4708499453429927efd7a" + }, + { + "Text": "mirror", + "URL": "http://old.mac.gdn/apps/mystscreensaver.sit" + }, + { + "Text": "54e17afffb1f755f4dc19f39ef717483", + "URL": "http://macintoshgarden.org/arch_md5.php?filename=mystscreensaver.sit" + } + ] + }, + { + "Title": "a-dark-3-prefs.sit", + "Size": "1.22 KB", + "OS": "For\n\t\t\t\t\t\t\t\t\t\t\t\t\t\tSystem 7.0 - 7.6", + "Links": [ + { + "Text": "www", + "URL": "http://download.macintoshgarden.org/apps/a-dark-3-prefs.sit?expires=1776922480\u0026token=cWRrVPNM51syzI3AanEYqg\u0026st=02efece000093e06f20ef6ca61f222bd" + }, + { + "Text": "mirror", + "URL": "http://old.mac.gdn/apps/a-dark-3-prefs.sit" + }, + { + "Text": "3c3633a865eddb97102f9b58230e4c7a", + "URL": "http://macintoshgarden.org/arch_md5.php?filename=a-dark-3-prefs.sit" + } + ] + }, + { + "Title": "Myst_Screen_Saver-hybrid_CD.iso_.sit", + "Size": "49.07 MB", + "OS": "For\n\t\t\t\t\t\t\t\t\t\t\t\t\t\tSystem 7.0 - 7.6", + "Links": [ + { + "Text": "www", + "URL": "http://download.macintoshgarden.org/apps/Myst_Screen_Saver-hybrid_CD.iso_.sit?expires=1776922480\u0026token=ipRxePsCn8DcILxclNKTow\u0026st=2c7a71c4be571db21ac67f9b0ef0772b" + }, + { + "Text": "mirror", + "URL": "http://old.mac.gdn/apps/Myst_Screen_Saver-hybrid_CD.iso_.sit" + }, + { + "Text": "ed8267c8f9c2747489c2df577556fca7", + "URL": "http://macintoshgarden.org/arch_md5.php?filename=Myst_Screen_Saver-hybrid_CD.iso_.sit" + } + ] + }, + { + "Title": "Myst_screensaver_images.zip", + "Size": "21.77 MB", + "OS": "For\n\t\t\t\t\t\t\t\t\t\t\t\t\t\tSystem 7.0 - 7.6", + "Links": [ + { + "Text": "www", + "URL": "http://download.macintoshgarden.org/apps/Myst_screensaver_images.zip?expires=1776922480\u0026token=e3WLlrubrXp167dV_sj2Xw\u0026st=8d4813d0d15e77034f94b9afa8df0751" + }, + { + "Text": "mirror", + "URL": "http://old.mac.gdn/apps/Myst_screensaver_images.zip" + }, + { + "Text": "2988714aa8daea162d836dac465beea4", + "URL": "http://macintoshgarden.org/arch_md5.php?filename=Myst_screensaver_images.zip" + } + ] + } + ], + "Screenshots": [ + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-01.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-02.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-03.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-04.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-05.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-06.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-07.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-08.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-09.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/myst-scrnsvr-10.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/Myst_SS_front.jpg", + "http://macintoshgarden.org/sites/macintoshgarden.org/files/screenshots/Myst_SS_back.jpg" + ] + } + }, + "http://macintoshgarden.org/apps/clarisworks-2": { + "fetched_at": "2026-04-21T11:34:03.9289679+10:00", + "software_item": { + "Title": "ClarisWorks 2.0 \u0026 2.1", + "URL": "http://macintoshgarden.org/apps/clarisworks-2", + "Description": "See also: ClarisWorks 1, ClarisWorks 3, ClarisWorks 4, ClarisWorks 4 for Teachers, ClarisWorks 5, AppleWorks 5, AppleWorks 6, AppleWorks 6 J\n\nThe ClarisWorks 2.0 install sets are 68k native, only.\n\nThe ClarisWorks 2.1 install sets are FAT; 68k \u0026 PPC native.\n\nDL #1 is useful if you want to install this version of ClarisWorks to a 68k Macintosh, including Mini vMac \u0026 Basilisk II.

The repository root is the module root; the `/go` suffix was redundant and confusing for tooling and newcomers. All import sites rewritten across the codebase. Go doc comments in CLAUDE.md updated to match. Step 0 of the architectural refactor plan (.claude/plans/review-the-architectural-layout-splendid-squirrel.md).

Every consumer now imports the underlying package directly. - appletalk.Datagram → ddp.Datagram - appletalk.DDPChecksum → ddp.Checksum - appletalk.MaxDataLength → ddp.MaxDataLength - appletalk.DatagramFromLongHeaderBytes → ddp.DatagramFromLongHeaderBytes - appletalk.DatagramFromShortHeaderBytes → ddp.DatagramFromShortHeaderBytes - appletalk.MacRomanToUpper → encoding.MacRomanToUpper - appletalk.MacRomanToUTF8 → encoding.MacRomanToUTF8 - appletalk.UTF8ToMacRoman → encoding.UTF8ToMacRoman - appletalk.Packet → new protocol.Packet (in new protocol/ package) The Packet interface moves to the new top-level protocol/ package, which will host cross-protocol contracts as the wire-format code is lifted out of service/ in later steps. Step 1 of the architectural refactor plan.

Consolidates duplicated MAC parsing previously in cmd/omnitalk's parseMAC and service/macip's fabricateMACForAT. - cmd/omnitalk/main.go: parseMAC replaced with hwaddr.ParseEthernet; helper deleted. - service/macip/dhcp_client.go: fabricateMACForAT delegates to hwaddr.MacIPEthernetFromAppleTalk, preserving the exact on-wire layout used by existing DHCP leases (0x02 | net | node | 'M' | 'I'). - Round-trip and validation tests in pkg/hwaddr/. Further call-site migrations (ethertalk.New accepting hwaddr.Ethernet, port/localtalk GenerateLocalTalk adoption) will land alongside Step 10 (BridgeConfigurable / ethertalk.Options) where the surrounding signatures change anyway. Step 2 of the architectural refactor plan.

Replaces the two duplicated mock files that previously lived in service/ and service/zip/. - service/mock_router_port_test.go: deleted. The service package had no test consumers; this file was dead code. - service/zip/mock_test.go: reduced to a pair of type aliases so the existing zip tests keep compiling under their familiar names. - service/zip/name_information_test.go: mock factories now delegate to testutil.NewMockPort/NewMockRouter; field-mutation sites updated to exported casing. NewAFPHarness is intentionally deferred to Step 15 when AFP decomposition lands; building it now would freeze an API that step will reshape. Step 4 of the architectural refactor plan.

The "log" stdlib import is removed from the package. netlog remains the interim transport; Step 6 replaces it with pkg/logging (slog-based) and Step 7 migrates all call sites. Step 5 of the architectural refactor plan.

The netlog package body is otherwise untouched; only the header comment changes to mark it deprecated.

A pkg/logging root logger is built with a console sink at the configured level, set as slog.Default, and handed to netlog.SetLogger. The shim keeps dual-mode behaviour: when no logger is installed (e.g. in tests that haven't initialised slog), Debug/Info/Warn still emit through stdlib log for backward-compat with tests that capture log.SetOutput. Once SetLogger runs, every netlog call flows through slog with the "source":"OmniTalk" attribute; sub-components get their own source tags in a follow-up pass that replaces netlog call sites with logger.With("source", "AFP")-style constructors. This delivers the plan's behavioural outcome (structured slog output with handler fan-out available) while deferring the ergonomic constructor threading to a later commit.

Constants are renamed to drop the CNID prefix (cnid.Root, cnid.Invalid, cnid.ParentOfRoot) since the package name already provides that context. service/afp keeps the AFP-coupled backend adapters (MemoryCNIDBackend, SQLiteCNIDBackend) and aliases the pkg/cnid types so the ~16 existing callers inside AFP (volume, fork, directory, path_codec, tests) keep compiling unchanged. The SQLite Desktop DB helper now calls cnid.OpenSQLiteDB directly so the same per-volume database can back both CNID and Desktop storage without duplicating the pragma setup. Follow-ups: tighten the backend registry (plan step 21) so third- party filesystems can plug their own Store implementation; move the CNID backend selection out of AFPOptions into the volume config subtree.

stop type-asserting PcapPort in main Step 10 of the architectural refactor. Introduces port.BridgeConfigurable as an optional interface for ports that need operator control over Ethernet bridge mode and host-MAC synthesis. cmd/omnitalk/main.go now obtains these knobs via interface assertion instead of depending on the concrete *ethertalk.PcapPort type. This keeps transports that don't need bridge configuration (LocalTalk, LToUDP, future virtual ports) from being forced to implement stubs, and sets up the eventual move to construction-time PortOptions.

Adds pkg/telemetry with Counter, Gauge, and Histogram types backed by expvar (stdlib, zero deps). A future //go:build otel file can replace the expvar publishers with an OpenTelemetry backend without touching call sites. Initial counters wired: - omnitalk_router_frames_in_total: incremented on every Router.Inbound - omnitalk_afp_commands_total: incremented on every AFP HandleCommand - omnitalk_aarp_probe_retries_total: incremented on every AARP probe retry Metric declarations live in per-package metrics.go files to avoid churning existing imports. The Prometheus-style naming convention is documented in the package doc comment.

The AppleDouble v2 sidecar format (parse/build, magic/version/entry-id constants, SidecarPath) is generic to any AFP-style server and is no longer buried in service/afp. service/afp/appledouble.go shrinks to a thin alias layer that keeps the historical lowercase identifiers compiling. AFP I/O code (appledouble_backend.go, desktop_rebuild.go) updates to the exported field names on appledouble.Parsed. The AFP-specific ForkMetadataBackend stays in service/afp/ — it depends on Volume config and disk I/O. A future step may relocate it to service/afp/fork/ once the package is decomposed (Step 15). Adds round-trip tests for the new pkg/appledouble package.

The pre-existing FrameSender interface in port/localtalk/localtalk.go was unused; backends plugged into Port via a ConfigureSendFrame(closure) call. Adds SetFrameSender as the interface-shaped counterpart and migrates the LToUDP and TashTalk backends to it. Each backend now exposes an exported SendFrame method that satisfies FrameSender, with the legacy unexported sendFrame retained as the implementation. ConfigureSendFrame is kept for the virtual/test backends that pass ad-hoc closures.

The three pending.Wait(context.Background()) sites — completeWrite, sendTickle, SendAttention — now use s.drainCtx() so background ATP transaction releases stop promptly when the server quits. * service/llap: the CTS-wait select grew <-st.stop and <-s.stop arms alongside the timer; time.After replaced with time.NewTimer so the timer is properly stopped on early return. * service/macip dhcp_client: dhcpClient now carries the service stop channel; RequestIP returns nil immediately on shutdown rather than waiting up to dhcpTimeout. * service/macip etherlink: resolveMAC's ARP-reply wait selects on l.stop alongside the timer; the waiter cleanup logic moved into dropARPWaiter so timeout and shutdown paths share it.

Mon Sep 17 00:00:00 2001 From: pgodwin Date: Sun, 26 Apr 2026 11:54:05 +1000 Subject: [PATCH 027/116] Step 28: wrap aggregated Stop errors with errors.Join Replaces the single %v formatting of the AFPService.Stop error slice with errors.Join + %w so callers can errors.Is/As against any of the underlying transport or backend Close errors. Wider audit: the codebase already wraps with %w everywhere a chained error is reported, and the existing reliance on stdlib sentinels (fs.ErrPermission, fs.ErrNotExist) covers the categories the plan suggested adding bespoke AFP sentinels for. No new sentinels needed.

The harness only asserts non-panic — any malformed inbound frame must surface as an error, never as a runtime crash on the router fast path. Smoke run at -fuzztime=2s exercises ~320k inputs cleanly. Future protocol/ packages (atp, asp, dsi, afp wire models) get the same treatment when their wire code lands behind the protocol/* split.

Fixes the one go vet finding the new gate would surface: ASP SessionManager.Close() was copying a Session containing sync.Mutex into a local snap before invoking the onClose callback. Callers only need a pointer (the session is already removed from the map and its writers are cancelled), so the snap is gone and onClose receives sess directly.

Root struct shape is preserved so consumers (cmd/omnitalk) compile unchanged. Renames LoadINI -> Load and the cmd-side shim loadConfigFromINI -> loadConfigFromFile. Auto-detect file changes from server.ini to server.toml. Test fixtures rewritten in TOML; server.ini.example, server.ini, dist/server.ini renamed to .toml with content converted. Docs and packaging scripts updated to match.

The Root struct, Defaults(), and DefaultMacGardenVolumePath move out: the config package no longer knows about any specific component's schema. Volume parsing migrates to service/afp.LoadVolumes — AFP's own schema lives with AFP, including AppleDouble mode parsing and the MacGarden default-path helper. Future services can self-register the same way without touching the config package. cmd/omnitalk keeps its typed fileConfig for now; resolveFileConfig is the cmd-side adapter that maps koanf paths to that struct. This lets the rest of main.go keep compiling unchanged while the source/schema boundary is now correctly placed.

+1000 Subject: [PATCH 033/116] Step B2: AFP owns Config struct; volumes move under [AFP.Volumes.*] MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit service/afp.Config is the typed schema for the AFP section, with koanf tags so any source (TOML, JSON, env) can populate it without coupling the service to koanf. Defaults live in afp.DefaultConfig(); logical validation lives on Config.Validate(). Volumes is now a map keyed by section name and roots under [AFP.Volumes.*] in TOML, scoping the volumes to the service that owns them. cmd/omnitalk reads AFP through cfg.AFP rather than scattered AFP* fields. The cmd-side adapter unmarshals [AFP] onto a defaulted afp.Config via koanf, then calls Validate(). Future services follow the same shape: each declares its own Config, defaults, and Validate. Per-volume cnid_backend / use_decomposed_names / fork_backend are removed — those settings now live on [AFP] directly. appledouble_mode remains per-volume with a top-level fallback. Tests, server.toml, server.toml.example, and dist/server.toml updated to the new section layout.

charset=UTF-8 Content-Transfer-Encoding: 8bit Same shape as afp.Config: each package declares Config with koanf tags, DefaultConfig(), and Validate(). cmd/omnitalk/config_ini.go gains a generic loadSection helper that unmarshals via koanf and runs Validate on a validatable interface, so the cmd-side adapter no longer copies fields by hand. - port/ethertalk: Config with Backend/Device/HWAddress/BridgeMode/ BridgeHostMAC/SeedNetwork{Min,Max}/SeedZone/Desired{Network,Node}. - port/localtalk: LToUDPConfig + TashTalkConfig. - cmd/omnitalk: fileConfig embeds the typed sections; main.go and config_test.go consume cfg.LToUDP.*, cfg.TashTalk.*, cfg.EtherTalk.*. Components don't import koanf — they only declare struct tags and Validate(). The cmd adapter owns koanf wiring.

A binary built without -tags afp is router-only — it bridges AppleTalk between EtherTalk, LocalTalk, and (with -tags macip) MacIP without pulling in AFP's SQLite/CNID/AppleDouble/macgarden dependency surface. Mirrors the existing macip pattern: - cmd/omnitalk/afp_hook.go (neutral): AFPHook interface, AFPSessionHooks (so MacIP can pin DHCP leases to ASP sessions without either subsystem importing the other), and AFPWiring/AFPFlagInputs carriers. - cmd/omnitalk/afp_enabled.go (//go:build afp): real wireAFP that loads the [AFP] section, applies flag overrides on the flag-only path, and builds the afp.Service plus its ASP/DSI transports. - cmd/omnitalk/afp_disabled.go (//go:build !afp): warns if the operator asked for AFP via flags or [AFP] in the TOML, returns a no-op hook. cmd/omnitalk/config_ini.go is now AFP-free; loadConfigFromFile returns the raw config.Source alongside fileConfig so wireAFP can read its own section on the //go:build afp side. main.go's 80-line AFP block becomes a single wireAFP call that AttachMacIP can connect to the macip hook. Tagged 64 files in service/afp,asp,dsi plus extension_map.go and the AFP-specific cmd tests. config_test.go is split: the AFP-specific TOML parsing tests move into config_afp_test.go behind the afp tag; the MacIP and ports tests stay neutral. Build matrix verified: go build ./... (router-only) go build -tags afp ./... go build -tags macip ./... go build -tags "afp macip" ./... go build -tags "afp macip macgarden" ./...

This is the regression guard the plan calls for before migrating *_models.go files from bytes.Buffer/binary.Write to MarshalWire/UnmarshalWire/WireSize via pkg/binutil. Future model migrations land one file at a time and must keep this golden green.

Each entry names the command, supplies a request constructor, and binds a Service-method handler. The sole quirk -- FPLogin's request decoder expects the command byte already stripped -- is now a per-spec stripCmdByte flag rather than special-cased after the switch. HandleCommand becomes a uniform unmarshal/log/dispatch/marshal loop. server.go drops from 1,582 to 1,103 LOC. Behavior and wire output are unchanged; the AFP test package and full build matrix (plain, afp, afp+macgarden, afp+macip+sqlite_cnid) still pass.

Moved into a new filedir_pack.go alongside the related FPGet*ParmsRes models. server.go drops 1102 -> 848 LOC and now imports neither "bytes" nor "encoding/binary". handleEnumerate's per-entry packing also extracted into a self-contained packEnumerateEntry helper so the paging/budget loop no longer interleaves wire-packing concerns. Byte-for-byte identical output. Both moves preserve the Service receiver — the resolver layer (CNID, metadata, FS capabilities, ExtensionMap) is still entangled with Service state. Splitting that into a pure FileInfo model is the next step but is large enough to land on its own.

These bridge the AFP-visible filesystem (no ._sidecar files, no .AppleDouble folders, no per-volume CNID DB) and the host filesystem where those artefacts physically live. - volume.go gains catalogNameForPath. AFP shows the configured volume name (not the host directory basename) as the root entry's catalog name, so the override belongs alongside the volume parameter packers. - filedir_pack.go gains toAFPTime. The Mac-epoch (1904) seconds converter is only called by the file/dir parameter packers; it lives with them now. Also drops the now-unused io/fs, os, time, and pkg/cnid imports from server.go and clears two stale doc comments orphaned by earlier moves. server.go drops 597 -> 470 LOC.

The packet parser, LkUp-Rply builder, control-code constants, and the small case-insensitive name/zone match helpers are pure wire format — they don't belong in the service that happens to host the registry. protocol/nbp/nbp.go now owns Tuple, Packet, ParsePacket, BuildLkUpRply, NameMatch, ZoneMatch, and the SASSocket / DDPType / Ctrl* constants. service/zip/name_information.go consumes them: the 25-line byte-arithmetic preamble in handlePacket collapses to a single ParsePacket call, and the buildLkUpRply / nbpMatch / nbpZoneMatch helpers become one-line shims so the rest of the file reads naturally. zip.NBPSASSocket / zip.NBPDDPType remain re-exported for callers (service/asp, service/macip) that already imported them.

This lets a future caller (e.g. an ATP transaction handler) cancel a slow DHCP exchange without waiting the full dhcpTimeout, which is the real motivation for Step 24's "uncancellable hardcoded timeouts" critique. Other Step 24 sites are already covered or out of scope for this slice: - service/asp/asp.go drain goroutines already use s.drainCtx() backed by a lifecycle context set up in Start(). - service/macip/etherlink.go resolveMAC has no ctx-bearing caller path worth wiring through yet; deferred until the IP send path itself takes ctx. - service/llap/llap.go CTS wait already selects on its service-stop channel; that's the appropriate scope for that loop.

Each loop now also selects on ctx.Done() (the Service.Start parent ctx), so cancelling the router cancels the loop directly. Stop() Wait()s on a per-service WaitGroup before returning.

Living in the middle was the real cost — service code couldn't tell which package to reach for and 50+ stdlib log.Printf calls sat in AFP because "the migration" was supposed to absorb them. Decision: netlog is the call-site API; pkg/logging is the slog factory used once at startup. Document the split, replace the lingering log.Printf calls in service/afp with netlog.Debug (Warn for the panic recovery), and delete the speculative pkg/logging/protolog package.

The pointers then lied about their provenance, and a few EtherTalk flags (desired_network, desired_node) were silently dropped from the TOML path because the writeback block didn't include them. Add flagsToConfig to translate flag values into the same appConfig that loadConfigFromFile produces. main.go now picks one builder, then reads only from cfg. Renames fileConfig to appConfig and incidentally fixes the dropped desired_network/desired_node TOML keys.

AFP picks the smallest non-zero limit and applies it to its filesystems; DSI reports 0 (uncapped TCP stream). This removes the post-construction mutation pattern, makes the contract explicit on the Transport interface, and lets AFP own when the limit is applied instead of trusting transports to call into it at the right time.

Split into: DatagramRouter — Route/Reply/PortsList/Zones (every service) RouteIndex — RoutingEntries/Get/Consider/MarkBad/Age (RTMP, ZIP-sending) ZoneIndex — ZonesInNetworkRange/NetworksInZone/AddNetworksToZone (ZIP) service.Router stays as the union so the Service.Start contract is unchanged. Internal stash fields (asp, macip) and helpers (rtmp.makeRoutingTableDatagramData, RoutingTableAgingService) narrow to the smallest capability they actually use, so future widening of Router doesn't ripple through them.

Fork I/O (Open/Close/Read/Write/Flush*/ GetForkParms/SetForkParms/ByteRangeLock) is the hottest AFP code path — every active session touches it on every read or write — so isolating it from auth, desktop, and volume traffic on a separate lock is the largest contention win of the four substruct moves. Helpers: forks.register — installs a handle, returns new fork id forks.get — RLock + map lookup; the hot Read/Write probe forks.close — drops a fork id and evicts its byte-range locks forks.snapshot — copy of all open handles for the volume-wide FPFlush forks.lock — write-lock the whole struct (used by ByteRangeLock, which needs atomicity across handle check + lock-list scan + insertion) maxReadSize stays on Service: it is set once at Start, read-only afterwards, not actually fork state.
