feat(network-access): add the network_access_provider.v1 capability - #21
Merged

Conversation
Silo-Server/silo-server#1001 settled on shipping overlay-network access (Tailscale via tsnet first) as a plugin that owns the overlay listener and reverse-proxies to the host. The SDK had no capability for it and no way for a plugin to learn the host's local listeners, keep per-instance state, or push status. Add the NetworkAccessProvider service (Connect, Disconnect, GetStatus), a typed NetworkAccessProviderDescriptor on CapabilityDescriptor (field 11), and three RuntimeHost additions: GetHostInfo gains host role, host name, node id, an ingress token, and the listeners to expose; ReadInstanceState and WriteInstanceState give each plugin instance a host-scoped encrypted key-value store sized for tsnet node state; ReportNetworkAccessStatus pushes state changes. runtimehost ships an InstanceStateStore matching the two-method shape of tailscale's ipn.StateStore without importing tailscale, plus typed HostInfo fields and state constants. Manifest validation requires the descriptor on the capability and a path-safe provider slug. A stub example plugin exercises the contract without a tsnet dependency so silo-server can use it as a test fixture. All proto changes are additive. CapabilityServers gains a thirteenth field, so plugins using an unkeyed composite literal must switch to keyed fields; the compat test documents this.

restoreLocked marks restoration complete before reading instance state. If the first ReadInstanceState call fails transiently, every later GetStatus skips restoration and continues reporting disconnected even when desired_connected=1 is persisted. This prevents the restart fixture from honoring the reconnect contract. Mark restoration complete only after the state read succeeds.

Fixed in 2da2393: restoration now retries on a read error, write failures are returned to the RPC caller, and a zero DefaultPort maps to the provider default origin without a port.

DefaultPort == 0 is documented to mean “use the provider default,” but this line formats zero directly into the listener URL. A host using that supported value receives https://stub.invalid:0 as the API and listener origins, advertising an unusable endpoint. Omit the port or substitute the provider default when it is zero.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a substantial resident network-access capability with new gRPC/protobuf contracts, host-managed state, reverse-proxy credential handling, and runtime lifecycle behavior. The public contract also has unresolved concerns around duplicate provider descriptors and protobuf/API conventions, so the change warrants human review. You can add or adjust custom eligibility rules. Learn more. |

Enforce one network-access provider descriptor per plugin installation.
capabilities is repeatable, and the supplied validator accepts every valid network_access_provider.v1 descriptor. The singleton provider service and its status messages contain no capability ID. A manifest with two providers therefore cannot route Connect, GetStatus, status reports, or instance state to a specific provider. Reject duplicate network-access descriptors, or add capability identity and isolated state to the protocol.

#1001 settled on shipping overlay-network access (Tailscale via tsnet first) as a plugin. The host could not run such a plugin: plugins started lazily on first RPC and never restarted, had no per-instance state store, no way to learn the local listeners, and no way to tell the host which network a request came in on. Stream URLs handed to clients always used a proxy's LAN or public address, which an overlay client cannot reach. Resident plugins: any enabled installation declaring network_access_provider.v1 starts after the API listener binds, restarts on exit with 1s to 60s backoff, parks after ten consecutive failures, and stops before HTTP drain. pluginhost gains an exit watcher and a start sequence so a newer supervisor generation never adopts a launch an older one started through the singleflight join. The admin installation record carries a runtime block and a restart operation; the web plugins page reads it. Host services: GetHostInfo is implemented (role, node id, listeners, an ingress token), plus ReadInstanceState and WriteInstanceState over a new plugin_instance_state table encrypted per row and scoped by installation and host, and ReportNetworkAccessStatus. Access path: the plugin stamps a per-start X-Silo-Ingress-Token on the requests it proxies. Middleware on the API, Jellyfin, and ABS listeners maps it to a provider and strips it. Proxy nodes report each provider's overlay origin in the health pull, stored in stream_nodes.network_access, and Node.ClientURLFor picks the origin for the request's path. Proxies without an origin for that path drop out of eligibility so the existing API-relative fallback applies. WebSocket origin checks accept the overlay origins of connected providers. The prepared-download preflight now dials the proxy's backend URL, since the overlay origin may not resolve from the API process. Proxy mode runs the same installation with a node:<id> state scope, rehydrates the archive from plugin_archives into its own cache dir, and reconciles on a plugins-changed Redis event and a 60 s poll. Admin routes under /api/v2/network-access fan status, connect, and disconnect out to every enabled proxy over its backend URL with the node bearer. Pins silo-plugin-sdk to the network-access branch; swap to v0.16.0 once Silo-Server/silo-plugin-sdk#21 is tagged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…zero DefaultPort Review findings on the hello-network-access stub: restoreLocked marked restoration complete before the read succeeded, so a transient host error turned persisted intent into disconnected for the process lifetime; instance-state write failures were only logged, so an admin's connect or disconnect could report success while the intent was lost; and a listener with DefaultPort zero produced the unusable origin host:0 although zero means provider default.

…ort (#1096) * feat(plugins): resident network-access providers with proxy-node support #1001 settled on shipping overlay-network access (Tailscale via tsnet first) as a plugin.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * build(deps): pin silo-plugin-sdk v0.16.0 Silo-Server/silo-plugin-sdk#21 merged and was tagged; replace the branch pseudo-version with the release. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): address review findings on resident providers Review findings on #1096, each with a regression test: - netaccess.Broker serializes Issue and Revoke so an old process's revoke can no longer forget the status a replacement pushed between the registry revoke and the cache forget. - A superseded successful launch is stopped when its entry is parked (stopped or failed), not only when the entry is gone or the supervisor halted; a launch a newer starting generation may adopt is still left to that generation's start-sequence check. - A failed provider RPC on a running process reports unavailable to the status sink so a dead overlay origin stops being advertised to the origin check and the node health report. - Instance-state writes take a per-scope transaction advisory lock so concurrent first writes of distinct keys cannot overshoot the 256-key budget. - Duplicate provider slugs resolve to the lowest enabled installation id everywhere (provider list, commands, node health map) with a warning, instead of the first-listed installation on one path and map order on another. - A proxy rehydrating a stored archive checks the binary's platform against its own and refuses a foreign one with a clear error; the archive was resolved for the API server's platform at install time. Documented as a same-platform requirement for this release. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): reject null host selectors and stop providers on disabled proxies Second round of review findings on #1096: - {"hosts": null} on connect and disconnect decoded to the same nil as omission, which means every host. The command body now records an explicit null in its decoder and the operation answers 422 for it; RawBody was not used because it would make the optional body required in the document. - A proxy's resident gate only checked that its stream_nodes row existed, so a disabled or retyped node kept serving overlay ingress while the API no longer listed it as a host that could be disconnected. The gate now requires an enabled proxy row. - Every unavailable answer from applyNetworkAccess reports to the status sink, not only the RPC-failure path, so a parked or gated instance's cached origin is dropped as well. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): pin silo-plugin-sdk v0.16.1 and cover host callbacks after idle Live testing with the stub provider on a sandbox (API server plus one proxy and one transcode node) found that a provider connected more than five seconds after its process started could never reach the host: go-plugin drops the pending broker stream after five seconds and the SDK dialed it lazily on the first Host() call. Connect then timed out on every host. Silo-Server/silo-plugin-sdk#22 (v0.16.1) dials at bind time. The resident fixture's GetStatus now makes a host call and reports whether it worked, and a new test idles six seconds after start before the first callback. It fails against v0.16.0 and passes against v0.16.1. The resident test host binds the RuntimeHost broker so fixtures can call back at all. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): never run a duplicate-slug provider; no timestamp on unavailable Review findings on #1096: - The resident set excluded nothing, so a second enabled installation declaring an already-owned provider slug kept running and serving ingress while every command and status read addressed the owner. The supervisor now derives ownership the same way the provider list does and does not start the duplicate on any host. - An unavailable answer synthesized by the host carried updated_at set to now, but the contract defines that field as when the host last heard from the provider and says it is absent while unavailable. The cache still stamps its own copy; the wire status carries none. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): drop status pushes from revoked processes; restart on node identity change Review findings on #1096: - A status push in flight while its process was being stopped, crashed, or replaced could land after the revoke and write a stale connected origin back into the cache; on a proxy the next health sweep then persisted a dead origin. The broker now accepts a push only from the process holding the installation's current ingress token, checked under the same lock Revoke takes, and the host RPC drops the rest. - A proxy whose stream_nodes row was deleted and re-registered resolved a new id, and the per-call state scope followed it while the running provider kept the old identity in memory. The supervisor now tracks the host identity each resident was started under and replaces every running resident when it changes; the proxy supplies its node scope. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): close network access lifecycle races Bind provider status to process generations, pin proxy state scopes, recover missed lifecycle events, and expose resident restart controls. Add provider-specific status fan-out and refresh generated contracts.\n\nReviewed PR: #1096\nValidation: focused Go tests, database-backed generation tests, web tests (579 files/4318 tests), Go build, go vet, route/OpenAPI/fixture/ledger gates.\n\nAI disclosure: OpenAI Codex CLI using gpt-6-astra through T3 Code; implementation and review fixes were AI-assisted and human verified. * fix(plugins): serialize reconciles, make admin restarts durable, repair the merged tree - Reconcile is serialized end to end (Macroscope finding on #1096): the desired set and gate result are computed outside the state lock, so two overlapping reconciles could apply results in the wrong order and an older one could resurrect a resident a newer one had removed. Test races eight reconciles against a disable under the race detector. - RestartInstallation now advances runtime_generation before restarting locally, so a proxy whose lifecycle subscription missed the event replaces its process on the next poll and a failed entry's budget is cleared there too. This makes TestResidentPollRecoversMissedRestartOfFailedProvider from the previous commit pass; it had no writer for the generation it waited on. - The worker route inventory count includes the per-provider proxy status route the previous commit added. - gofmt under the toolchain CI pins (go.mod says 1.26.4) reflows one struct the previous commit left misaligned; the local 1.26.5 accepted it, which is why it slipped through. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): replace a follower's process once per admin restart Review findings on #1096: - With the restart recorded as a runtime_generation bump, publishing a restart event as well made a following proxy restart on the event and then replace the fresh process again on the reconcile that saw the new generation: two overlay outages and two token rotations per admin restart. The event is now a plain reconcile when the generation was persisted, and it is published whether or not this host runs the resident itself. Test: TestAdminRestartReplacesFollowerProcessOnce. - The broker idle test documents why it sleeps (go-plugin's five-second pending-stream window is a constant with no seam or signal) and that a late cleanup can only make it pass vacuously, never fail; it is skipped under -short. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): forward the host start sequence through the production adapter Review finding on #1096: the supervisor's superseded-launch check read NextStartSeq through a type assertion the production hostAdapter did not satisfy, so outside the test fake the floor was always zero and a newer generation could adopt a launch an older one had started. NextStartSeq is now part of the plugins.Host interface and the adapter forwards it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(plugins): reject a null command body, report ownership, refresh the restart receipt Review findings on #1096: - A literal null request body on connect and disconnect decoded to a nil body, which means every host. The input now records whether a body was sent at all and answers 422 for null; omission still means every host. - The admin installation view flagged every enabled installation with a resident capability as resident, including a duplicate provider slug the supervisor deliberately does not own, so the web page offered a restart that could not start anything. Once the supervisor is armed its entries decide; the capability is used only before boot finishes. - The restart receipt was built from the pre-restart row and carried a stale updated_at after the generation bump; it now reloads the row.

Related issue: Silo-Server/silo-server#1001
Overlay-network access (Tailscale via tsnet first, NetBird later) is going to ship as a Silo plugin that owns the overlay listener and reverse-proxies to the host. The SDK has no capability for that, and a plugin has no way to learn which local listeners to expose, keep per-instance state such as a tsnet node key without writing files, or tell the host when its connection state changes.
Approach
NetworkAccessProviderwithConnect,Disconnect, andGetStatus, and aNetworkAccessStatusmessage carrying state, hostname, origin, per-listener origins, an admin-only auth URL, error text, provider version, and plugin-owneddesired_connectedintent.CapabilityDescriptor.network_access_provider(field 11) names the provider slug and display name so the host can list providers without launching the plugin. Manifest validation requires it onnetwork_access_provider.v1capabilities and rejects it elsewhere.RuntimeHostadditions:GetHostInfogainshost_role,host_name,node_id,ingress_token, andlisteners(fields 4 to 8, plusHostListener);ReadInstanceStateandWriteInstanceStategive each plugin instance a host-scoped, host-encrypted key-value store (key 256 bytes, value 256 KiB, 256 keys per scope);ReportNetworkAccessStatuspushes state changes.runtimehost.InstanceStateStoreimplements the two-method shape of tailscale'sipn.StateStoreover those RPCs without importing tailscale.HostInfogets the typed fields and aListener(name)helper.

Every proto change is additive; existing plugins are unaffected on the wire.
CapabilityServersgains a thirteenth field, so any plugin that constructs it with an unkeyed composite literal must switch to keyed fields. The compat test inpkg/pluginsdk/runtimedocuments the change. Tag as v0.16.0; silo-server will pin it.Downstream coordination
GetHostInfoimplementation, instance state storage, and/api/v2/network-accessare built against this branch and follow once the tag exists.Validation
silo-server builds and its plugin, pluginhost, apiv2, proxy, and netaccess test suites pass against this branch through a local
replace.Risks
The
CapabilityServersliteral change is the only source-level break, and it only affects unkeyed literals.Checklist
