/home/byk/Code/opencode-v2-pilot/packages/plugin/src/promise/registration.ts: Registration exposes readonly dispose: () => Promise<void>, and ModelHookOptions exposes optional readonly providerID?: string, limiting a hook to one provider while unscoped hooks apply to every provider./home/byk/Code/opencode-v2-pilot/packages/plugin/src/promise/registration.ts: Hooks<Spec> registers a named callback returning Promise<void> | void; ModelHooks<Spec> additionally accepts options?: ModelHookOptions only when the hook input has readonly model; both return Promise<Registration>. Transform<Input> accepts a synchronous (input: Input) => void callback and returns Promise<Registration>./home/byk/Code/opencode-lore/packages/gateway/src/cli/start.ts lines 166-195: isLoopbackProbeUrl() recognizes localhost, localhost., ::1, and IPv4 addresses matching /^127(?:\.\d{1,3}){3}$/, stripping IPv6 brackets and lowercasing the hostname; malformed URLs return false. internalProbeFetch() uses nodeHttpFetch(url, init) for loopback URLs to bypass WHATWG’s browser forbidden-port list, while non-loopback remote/LAN URLs retain normal fetch() transport and semantics.probeGatewayIdentity() and probeGatewayIdentityDetailed() in /home/byk/Code/opencode-lore/packages/gateway/src/cli/start.ts: both default to a 1500 ms timeout and probe ${baseURL}/_lore/control with authorization: Bearer ${token}. A response is "authenticated" only when it is OK and JSON has status === "ok", service === "lore", and a positive safe-integer numeric pid; non-OK or malformed responses are "rejected", aborts are "timeout", and other exceptions are "unavailable". The compatibility wrapper returns the identity only for "authenticated", otherwise null.probeGatewayProcessStatus() probes every GatewayProcessRecord.hosts entry concurrently through probeGatewayIdentityDetailed(probeUrlFor(host, record.port), record.token, timeoutMs). Status precedence is: "authenticated" when any authenticated identity has pid === record.pid; otherwise "timeout" if any timed out; otherwise "rejected" if any was rejected; otherwise "unavailable".GatewayHealthStatus = "healthy" | "not-running" | "error" | "timeout" and probeGatewayStatus() in /home/byk/Code/opencode-lore/packages/gateway/src/cli/start.ts. It probes ${baseURL}/health with a default 1500 ms timeout through internalProbeFetch(), maps an OK response to "healthy" and a non-OK response to "error", maps aborts to "timeout", maps recursively detected ECONNREFUSED—including an AggregateError only when it has at least one error and every nested candidate is connection-refused—to "not-running", and maps other failures to "error".probeGateway() is a boolean compatibility wrapper returning whether probeGatewayStatus(baseURL, timeoutMs) === "healthy".probeUrlFor(host, port) maps wildcard bind hosts 0.0.0.0 → 127.0.0.1 and :: → ::1, then uses bracketHost() so IPv6 probe URLs are valid, e.g. http://[::1]:3207.probeGatewayProcessHost() concurrently authenticates a persisted GatewayProcessRecord against every bound host and returns the first host in list order whose identity PID equals record.pid, or null; probeGatewayProcess() returns whether such a host exists. Both default to 1500 ms.requestGatewayShutdown() concurrently sends token-authenticated POST requests to /_lore/control on every persisted host with a default 1500 ms per-host timeout. HTTP 404 maps to "unsupported"; other non-OK responses, exceptions, or malformed/mismatched bodies map to "failed"; "accepted" requires status === "ok", service === "lore", pid === record.pid, and shutdown === "requested". Aggregate precedence is "accepted" if any host accepts, then "failed" if any fails, otherwise "unsupported".firstReachableHost() probes all interfaces concurrently so one hanging interface cannot serialize per-probe timeouts, then returns the first host by original list order whose /health probe succeeds, or null. Its injectable probe defaults to probeGateway, allowing reuse through mocked/wrapped DaemonIO./home/byk/Code/opencode-lore/packages/gateway/src/cli/start.ts: daemonLogPath() returns join(dataDir(), "gateway.log"), and openDaemonLogFile() calls openRuntimeFileForAppend("gateway.log") for owner-only append, leaving closure to the caller.buildStartChildArgs(opts: StartOptions) reconstructs deterministic argv for the detached child of lore start --bg from typed options, deliberately omitting the daemonize flag to avoid recursive forking. Ordering is: "start"; optional --port <port>; one --host <host> per host in input order; then optional --debug, --local, --allow-remote-management, and --remote <remoteUrl>.isSeaBinary() calls require("node:sea").isSea() when available and returns false on missing/invalid API or exceptions. A packaged SEA binary uses process.execPath as the Lore program without a script path; dev/npm mode uses Node/Bun and must pass process.argv[1] first./home/byk/Code/opencode-lore/packages/gateway/src/lifecycle-lock.ts lines 981-1039: lockArtifactPrefix(lockPath, marker) produces .${basename(lockPath)}${marker}, and sameOwnerRecord() requires both sameFile(left.file, right.file) and identical content.createOwnerStage() creates an owner stage in the lock’s parent directory at ${lockArtifactPrefix(lockPath, ".owner.")}${owner.token}.${randomBytes(8).toString("hex")}.tmp, with an initialization-claim path ${lockArtifactPrefix(lockPath, INITIALIZATION_CLAIM_MARKER)}${owner.token}.createOwnerStage() securely opens the stage using O_WRONLY | O_CREAT | O_EXCL | NO_FOLLOW and FILE_MODE, verifies it is a regular file owned by the current user, applies fchmodSync(fd, FILE_MODE) except on win32, writes ${JSON.stringify(owner)}\n, fsyncs the file and parent directory, rereads it, and verifies token, pid, and processIdentity. A mismatch throws LifecycleLockLostError; cleanup closes any open descriptor and force-removes the stage before rethrowing.removeExpectedOwnerRecord() rereads an artifact before deletion, silently returns if it is missing, and refuses deletion with LifecycleLockLostError unless the current snapshot exactly matches the expected file identity and content; successful deletion uses unlinkSync() followed by parent-directory fsync.publishInitializationClaim() verifies the stage has not changed, hard-links it to stage.initializationClaimPath, and handles EEXIST only if the existing claim is exactly the same owner record; a different existing record throws LifecycleLockBusyError. It rereads and revalidates the published claim, throws LifecycleLockLostError if it changed, and fsyncs the containing directory.emptyLockDirectory() validates the lock directory before and after confirming readdirSync(lockPath).length === 0, returning the final Stats only when both validations describe the same generation. Missing paths and LifecycleLockBusyError return null; other errors propagate.initializationClaims() validates the parent directory before and after enumeration, selects entries beginning with lockArtifactPrefix(lockPath, INITIALIZATION_CLAIM_MARKER), requires each suffix token to match /^[A-Za-z0-9_-]{32,256}$/, and requires the owner record’s token to equal the token encoded in its path.
