M1 slice 7: amicode service activation wiring — parallel-run boot - #475
Merged
Conversation
…t at activation M1 slice 7 of #451: the extension-host amicode service now boots at extension activation, alongside the fork opencode server (the parallel-run harness — chat/widgets still hit the fork until the M3 cutover; the service is additive, never load-bearing). - amicode_service_wiring.ts (vscode-free): boot on an ephemeral loopback port, per-boot password mint (deliberately NOT the opencode server's — separate surfaces, separate credentials), log line for the output channel, disposal for ctx.subscriptions. A boot failure logs and returns undefined — activation must survive without the service. - extension.ts: boot + dispose after the ServerManager setup. Stateless service — no restart coupling with solver-mode switches or config re-preps (unlike the opencode server, whose config rides its env). - terminal.ts: the Amicode terminal env now exports AMICODE_SERVICE_URL + AMICODE_SERVICE_AUTH, so a dogfood machine can probe the port directly (curl $AMICODE_SERVICE_URL/amicode/profile with the header). Tests: boot/serve/401/dispose + failure path (vi.mock, separate file — hoisted mock). Full suite 1182/1182; typecheck clean.
📝 WalkthroughWalkthroughThe extension now starts an authenticated Amicode service during activation, exposes its URL and authorization header to terminal environments, logs startup outcomes, and disposes the service asynchronously. ChangesAmicode service integration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The service does not start on every activation path, leaving terminal integration unavailable in some environments, and a port-binding failure may terminate the extension host instead of being handled safely. These concrete availability and integration issues should be fixed before merging. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Make AmicodeServiceServer.start() reject listen errors.
At packages/extension/src/amicode_service/server.ts:140, start() resolves only from the server.listen() callback. A bind failure emits an unhandled error event, so the promise does not reject and the extension host can terminate. Register an error handler before listen(), clear this.server on failure, rethrow the error, and add a server-level test for the real listen-error path. The existing failure test only mocks a rejected start() promise.

Use the exported AmicodeServiceHandle contract.
Both sites duplicate the service connection shape. Import AmicodeServiceHandle from packages/extension/src/amicode_service_wiring.ts to prevent the terminal and activation contracts from drifting.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Start the service outside the local opencode branch.
Lines 735-741 run only when binary !== undefined and the host is not a fleet client. Fleet-client activation and missing-binary activation therefore skip the Amicode service and leave the terminal service variables undefined.
Start the service once before the fleet and local-server split. Register its disposal once for every activation path.

Part of #451 (M1 slice 7; not closing).
What's here
The consumer-facing wiring for the completed route port (all 31 routes, #463–#471): the extension-host amicode service now boots at extension activation, running in parallel with the fork opencode server — the M1 parallel-run harness. The chat and widgets still hit the fork until the M3 cutover; the service is additive and never load-bearing.
src/amicode_service_wiring.ts(vscode-free, unit-testable): ephemeral loopback boot, its OWN per-boot password mint (deliberately not the opencode server's — separate surfaces, separate credentials), output-channel logging, disposal. Boot failure → log +undefined; activation always survives.extension.ts: boot + dispose alongside the ServerManager. The service is stateless across requests (reads state at call time, same contract as the fork's routes), so it needs no restart coupling with solver-mode switches or config re-preps.terminal.ts: the Amicode terminal env now exportsAMICODE_SERVICE_URL+AMICODE_SERVICE_AUTH— a dogfood machine can probe the port directly (curl $AMICODE_SERVICE_URL/amicode/profile -H "Authorization: $AMICODE_SERVICE_AUTH").Rebased onto main after #473 (which unblocked main's typecheck + CI from the #450 fallout — both were landed red).
Verification
Wiring tests 3/3 (boot → serve with auth → 401 anonymous → disposal closes the port; failure path via
vi.mockreturnsundefinedand logs). Full suite 1182/1182; typecheck clean.Remaining M1 (tracked in the manifest): CSP/origin widening + the
?auth_token=iframe flow — these land with M2's app-bundle extraction, when a pane actually needs to point at the service origin.Summary by CodeRabbit
