chore(deps): upgrade Effect to rc.115 and Alchemy to its rc.115 preview build

[juliusmarminge]

Bumps Effect from 4.0.0-rc.112 to 4.0.0-rc.115 (effect, @effect/platform-node, @effect/platform-node-shared, @effect/platform-bun, @effect/sql-sqlite-bun, @effect/sql-pg, @effect/atom-react, @effect/openapi-generator, @effect/vitest) and Alchemy from 2.0.0-beta.76 to 2.0.0-beta.77. @effect/platform-node-shared stays pinned exactly in the catalog (#11208).

What changed in Effect

rc.113 was a breaking naming cleanup plus a few module moves. Most of the diff is mechanical:

• Config, Flag, Argument, Prompt constructors are PascalCase (Config.string → Config.String, Flag.integer → Flag.Int, Flag.choice → Flag.Literals, Prompt.confirm → Prompt.Confirm, Prompt.text → Prompt.String).
• SchemaTransformation.transformOrFail / SchemaGetter.transformOrFail → transformEffect; Config.mapOrFail → Config.mapEffect.

Non-mechanical changes:

• Mime moved from @effect/platform-node/Mime (a mime re-export) to effect/unstable/http/Mime, which returns Option and bare extensions. http.ts and imageMime.ts adapt; imageMime re-adds the dot before checking the safe-extension list.
• Socket dropped runRaw; DeviceHubProxy now pumps reader.pull batches into writer.writeAll for each direction. A close fails the pull, which still ends the race and tears down the other side. WebSocketConstructor now takes WebSocketConstructorOptions; the test constructors narrow it to protocols, which is all Socket.makeWebSocket passes.
• HTTP server addresses are NetAddress.SocketAddress instead of { _tag: "TcpAddress", hostname }. McpSessionRegistry builds the MCP endpoint from the bound IP with NetAddress.isUnspecified / formatIp / formatUrlHostString; the test cases now cover :: and ::1. A hostname can no longer appear there, so the localhost case is gone.
• File sizes are ByteSize and readAlloc takes a number: FileSystem.Size(n) → ByteSize.bytes(n) in GitManager and CursorSkills, http.ts converts the chunk size.
• JSON Schema generation defaults to open objects (onExcessProperty: "ignore"). The t3.json schema and the text-generation output schemas pass onExcessProperty: "error" to keep additionalProperties: false; the MCP preview tool result schemas go through Tool.getJsonSchema, which has no such option, so those two tests now expect additionalProperties: true.
• AgentSessionScanner.test used an mtime of now + 1ms; the Node BigInt stat that the Effect file system now uses floors sub-millisecond precision and rounded it back to now, so the fixture uses now + 1s.
• Alchemy beta.77 moved Cli to alchemy/Report, renamed ProfileLive to ProfileStoreLive, and its auth providers now require an Interaction service; infra/relay/scripts/deploy.ts provides layerNonInteractive() and LoggingCli gets PlatformServices for its prompt environment.
• The vendored effect patch was regenerated against rc.115 (three RpcClient pinger hunks moved because write became writer.write); the @effect/vitest patch was regenerated for the new import sites.

msgpackr-extract goes

Effect rc.113 dropped its msgpackr dependency; the Msgpack encoding module is gone and RPC serialization is JSON / NDJSON / JSON-RPC / SchemaBinary. The server only uses RpcSerialization.layerJson / layerNdjson, so msgpackr-extract (3.5 MB of native addon per platform) had no consumer left. It is removed from apps/server/package.json, the pnpm allowBuilds list, CLI_RUNTIME_EXTERNAL_PREFIXES, the WSL archive exclusions in build-desktop-artifact.ts, the knip ignore list, and docs/operations/release.md. detect-libc leaves the external list with it (it was only in the closure through node-gyp-build-optional-packages); node-gyp-build and node-addon-api stay because node-pty and the ws accelerators still need them. The external-closure test now anchors on node-pty and node-addon-api.

Not upgraded

Alchemy is pinned to a pkg.ing preview build (2365753e58, the head of alchemy-effect#1601, "effect 4.0.0-rc.115") rather than 2.0.0-beta.77. beta.77 on npm still calls the rc.112 constructor names at module scope (Config.string in Auth/Profile.js) and cannot load under rc.115; upstream fixed that on main after the release. Consequences, all meant to be reverted once Alchemy ships beta.78:

• blockExoticSubdeps: false in pnpm-workspace.yaml: the preview's own @alchemy.run/* and @distilled.cloud/* dependencies are pkg.ing tarballs, and pnpm has no per-package allowlist for URL subdependencies.
• The preview still pins the released @distilled.cloud/fly-io@1.0.0-rc.9 and railway@1.0.0-rc.9, which carry the same rc.112 call sites (two and four lines); both get a pnpm patch renaming them, and an overrides entry points their @distilled.cloud/core at the preview core so a single rc.115-compatible copy loads.
• scripts/sync-reference-repos.ts resolves a https://pkg.ing/<name>/<sha> pin to that commit, so vpr sync:repos keeps the vendored Alchemy reference in step (chore(refs): sync Effect and Alchemy references to rc.115 and the preview commit #11351).

With that, infra/relay tests pass (30 files, 284 tests) and scripts/deploy.ts loads and prints its help. The relay deploy itself has not been run.

Verified

• tsc --noEmit clean in apps/server, apps/desktop, apps/web, apps/mobile, packages/*, scripts, infra/relay.
• vp test run in scripts (285), packages/shared (664), packages/contracts, packages/client-runtime (1393), packages/ssh, packages/effect-acp, packages/effect-codex-app-server, packages/tailscale, apps/web (4710), apps/desktop (1291; the libsecret helper test needs libsecret-1 headers this box lacks), and the apps/server suites for src/persistence, src/mcp, src/device, src/http, src/server.test.ts, src/cli, src/bin.test.ts, src/project, src/git, src/provider/Drivers/CursorSkills, src/textGeneration (one pre-existing failure on this host: the Codex fake CLI cannot find node when spawned with an explicit env, reproduces on main).
• vp run build:bundle in apps/server: grep -c msgpackr dist/bin.mjs is 0, the inlined-externals scan reports none, node dist/bin.mjs --help runs.
• vp run knip:check clean.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This dependency migration includes production WebSocket, HTTP/MIME, MCP endpoint, schema, packaging, and relay deployment changes—not just API renames. The untagged Alchemy preview dependency and unexecuted relay deployment further warrant focused human review.

official pnpm 11 blockExoticSubdeps setting dependency resolution

💡 Result:

The blockExoticSubdeps setting in pnpm is a security feature designed to protect the dependency supply chain by restricting the sources from which transitive dependencies (subdependencies) can be resolved [1][2]. When blockExoticSubdeps is enabled (set to true), only direct dependencies (those explicitly listed in your root package.json) are permitted to use exotic sources, such as git repositories or direct tarball URLs [1][3]. All transitive dependencies must be resolved from trusted sources, such as a configured registry (e.g., npm, JSR), local file paths, or workspace links [1][4]. Key details regarding this setting include: - Default Status: As of pnpm 11.0, blockExoticSubdeps is enabled (set to true) by default [5][6]. - Purpose: It prevents untrusted or potentially malicious code from being pulled into your project via subdependencies using non-registry sources [1][3]. - Configuration: It can be configured in your pnpm project's settings, typically within the pnpm-workspace.yaml or global configuration [7][5]. If a dependency tree attempts to resolve a subdependency from an exotic source while this setting is active, pnpm will throw an error (ERR_PNPM_EXOTIC_SUBDEP) to prevent the installation [4].

Scope the transitive-source bypass before release.

pnpm@11.10.0 blocks exotic sources for transitive dependencies by default. Setting blockExoticSubdeps: false disables this protection for the entire workspace. The current comments explain the Alchemy preview exception, but no allowlist or CI check limits the bypass to @alchemy.run/* and @distilled.cloud/*. A future subdependency can therefore introduce an unexpected tarball or Git source.

When an Effect rc.115-compatible Alchemy release is available, remove this setting. Until then, add CI validation that rejects unexpected exotic lockfile sources and track removal with the Alchemy beta.78 upgrade.

Superseded by #12326: Alchemy 2.0.0-beta.78 is built against Effect rc.115, so the pkg.ing preview pins and provider patches are no longer needed.
