cli/serve --no-server, the remainder of #23623: the objectstack:listening IPC message and the runtime state file still announce http://localhost:PORT with nothing listening, and a config-mounted server's banner names an unmounted MCP route #23743

   Read in this act: the body in full, 0 comments.

   • Lane: domain:cli. Both halves land in packages/cli/src/commands/serve.ts.
   • Grade: p3.
     • This is the remainder of cli/serve: with --no-server the ready banner still prints "API: http://localhost:PORT/" and an MCP connect URL, though no HTTP server is composed and nothing listens #23623 (p3).
     • Half 1 breaks the documented objectstack:listening contract (content/docs/deployment/cli.mdx:269), but no in-repo consumer spawns --no-server with an ipc channel. Half 2 needs a config shape with no in-repo producer.
     • Not the protocol-first class: it pulls service behaviour back to a declared contract, and no door's accept set moves.
   • State: pm:queue. PR fix(cli): the ready banner prints API: and MCP: addresses only when an HTTP server is composed #23741 merged at 2026-10-15T23:57Z, which is the order the body names.
   • Labels: finding → bug.

   ⛔ Not a claim.

   Claim: PM loop round 1, the third slot of the maintainer's temporary concurrency (「临时并发可以加到3」; for this slot 「换一个卡派」, in place of #23863, which waits on PR #23862). Label order: the open pm:queue bugs left in domain:cli are p3; this is the oldest. #23743: on a --no-server boot, objectstack:listening and the runtime state file stop announcing an HTTP address nothing listens on, and the banner's MCP: row prints only when the route's owner is composed · 2026-10-16T10:37Z
   Session: session_01PFB9ZGRWYvjhTXsd8i6KBp
   Account: marchtian (the seat's linked user as GET /user answers it; always the card's assignee)
   Branch: claude/issue-23743-no-server-announcements
   Worktree: objectstack-issue-23743
   Domain: domain:cli
   Seat: domain:cli#1 (seat post #6024)
   File surface (read on origin/main 6422da58e8; line numbers move; stop on a breach and explain it in the report):

   • packages/cli/src/commands/serve.ts: publishBoundPort and its three channels (about :763-:870), the state-file write it drives, and the banner's MCP: gate beside readComposedHttpServer (about :531-:566).
   • packages/cli/src/utils/format.ts: the banner's MCP: row only, if the gate lands there.
   • content/docs/deployment/cli.mdx: the objectstack:listening / objectstack:seed-settled rows (:269-:270) only if the behaviour they state changes.
   • Their pins (new test files beside them under packages/cli/src/**), and one .changeset/23743-*.md.
   • ⛔ Hold-offs: the --no-server --preset minimal process lifetime (cli/serve: --no-server --preset minimal prints the ready banner ending "Press Ctrl+C to stop" and then exits 0 on its own about 40 ms later, removing the runtime state file it had just written #23744, next on this file in this seat's serial queue); packages/cli/src/commands/dev.ts (cli: the pnpm dev watcher prints only "✗ compile failed (Nms)" when a save is refused — the refusal goes to compile's stdout, which the watcher discards #23820, seat 2; its objectstack:listening consumer about :769 is read, not edited); packages/runtime.
     Container & model: M (three announcement channels and one banner row on a kernel-only boot, measured at the door), mode:subagent, model: TIER_DEFAULT (dispatch-gates --tier: no path-derived mandate)
     Clause-②: no
     Basis for the Clause-② line: it pulls the IPC message back to its documented contract. content/docs/deployment/cli.mdx:269: "objectstack:listening | os serve | The HTTP server is bound. Carries { port, url } — the port actually bound". A message announcing an address with nothing bound is outside that text. The state file has no documented contract (serve.ts calls it best-effort supervision), and the banner is human text. serve.ts is not reachable from @objectstack/cli's exports beyond the ServeCommand default. No packages/spec edit.
     Responsibility: packages/cli's os serve, platform code in this lane | none: PR fix(cli): the ready banner prints API: and MCP: addresses only when an HTTP server is composed #23741 made only the banner's API: row read whether a transport is composed | an external supervisor that spawns os serve --no-server with an ipc channel and trusts objectstack:listening; no in-repo consumer is reached (os dev never spawns --no-server); half 2 needs a config that mounts its own HonoServerPlugin, with no in-repo producer (both measured by cli/serve: with --no-server the ready banner still prints "API: http://localhost:PORT/" and an MCP connect URL, though no HTTP server is composed and nothing listens #23623's dev, report 6204307328)
     Thread-read: 6205610412
     Serial constraints cleared:
   • No open pm:dispatched claim names serve.ts, format.ts or packages/cli/src/** (all 25 newest claims read in this act). No open PR edits serve.ts: its last change on main is PR fix(cli): the ready banner prints API: and MCP: addresses only when an HTTP server is composed #23741 (2906cd8d2e).
   • cli/serve: --no-server --preset minimal prints the ready banner ending "Press Ctrl+C to stop" and then exits 0 on its own about 40 ms later, removing the runtime state file it had just written #23744 (p3, same file) is not folded: its claimant first establishes whether a kernel-only boot stays up or exits, and the fix differs by answer (fold gate ① fails). It runs after this card lands.

   "summary": "Both halves reproduced at the door on base 7a6ba03 before any edit. Half 1: production --no-server --preset minimal (ipc channel) received {type:'objectstack:listening', port:38393, url:'http://localhost:38393'} and found runtime.env_local.PROJECT.json with that url, and every probe answered ECONNREFUSED; --dev --no-server did the same. Half 2: a config-mounted HonoServerPlugin under --no-server printed MCP: plus its connect hint, while /api/v1/mcp answered 404 and /api/v1/data/fx_task answered 401. Fix, all in packages/cli/src/commands/serve.ts: the publish site runs publishBoundPort(...) only when httpServer === 'composed' and otherwise prints the banner alone. httpServer is the same resolveHttpServerComposition value the banner's address rows read, so one predicate decides all three channels. objectstack:seed-settled is still sent on such a boot and is its only message. The state file is not written on such a boot; its payload shape is unchanged. The banner's MCP: row now gets isMcpServerEnabled() && mcpRouteMounted, where mcpRouteMounted = httpServer === 'composed' && readComposedMcpRouteOwner(kernel), a new kernel read: kernel.hasPlugin('com.objectstack.runtime.dispatcher'), the plugin that mounts /api/v1/mcp. Both docs rows (cli.mdx :269-:270) were updated together. Zone 2 measured: (1) holds as stated. (2) The seed-settled consumers are the os dev relay (dev.ts:769, never spawns --no-server) and the docs example, which waits for seed-settled alone; SeedSettledMessage's no-hang rule decides that it is still sent, alone. (3) The state-file readers in this repo are scripts/publish-smoke.sh (spawns objectstack dev, reads .port, curls health) and CLI tests only; no docs contract exists; choice: not written. (4) No live route table exists on IHttpServer; the narrowest sound read is the kernel's plugin registry, which HonoServerPlugin already uses for the dispatcher name. Draft PR #23947 is open with assignee marchtian; CI is in_progress.",
   "tests": "New unit file src/commands/serve-no-transport-announcements.test.ts (10 cases): readComposedMcpRouteOwner against a real ObjectKernel (createDispatcherPlugin registered gives true; transport-only gives false); MCP_ROUTE_OWNER_PLUGIN read off createDispatcherPlugin().name; it asks for that name only; false when the kernel cannot answer; run() wiring source pins with comments masked. New integration file src/commands/serve-no-transport-announcements.integration.test.ts: 3 boots of bin/run.js with an ipc channel and a watched OS_HOME. (1) Production --no-server: no listening message, messages exactly ['objectstack:seed-settled'], no runtime.*.json ever created (expect.soft, 3 legs). (2) Control default boot: [listening, seed-settled], the message equals the API: row's {port,url}, the state file carries the same, MCP: row, health 200, /mcp not 404. (3) Hono --no-server: no MCP: row or hint, /mcp 404, IPC and state file carry the API: address. test-budget 30 from local runs of 19.4 / 18.9 / 20.9 s.

Shard 3: 918 passed. Shard 4: 1071 passed, 1 failed, a real one: serve-observability-registration.test.ts locates the transport by the first raw-source 'new HonoServerPlugin(' and my docblock spelled it; fixed in cccb00e. On final head cccb00e after rebuilding the CLI: 6 touched unit files 'Test Files 6 passed (6) · Tests 82 passed (82)'; integration, scoped (new file, serve-no-server-banner, test/serve-no-storage-boot-guard, test/dev-boot-output-order) 'Test Files 4 passed (4) · Tests 15 passed (15)'; OS_TEST_TIERS=nightly test/serve-publishes-bound-port.e2e.test.ts 'Tests 6 passed (6)'; the rest of the integration tier is declared to CI.

Result 'Tests 3 failed | 10 passed (13)': all three no-transport soft legs red (listening sent, not the only message, state file written), both wiring pins red, both controls green; direction: turned red, as predicted.

Result 'Tests 2 failed | 11 passed (13)' (Hono case 'an MCP: row printed for an unmounted route' and the mcpEnabled source pin); direction: turned red. Restore proven the same way, 13 passed.
