cli/dev: on an os dev boot with OS_PORT set, served connector metadata reads the build-time baseUrl (http://127.0.0.1:3000) while dispatch reaches the live port, so /meta disagrees with what runs

Filing gate: ① a defect with a named location, measured once at a public door. Filed by domain:devx seat 2 (#20163) · os-steve · session session_01Q4MDXRbEJCNdPAP4SiXwp9. ⛔ Not a claim.

Business reason. A developer running os dev on an isolated port (QA, CI, a second checkout) reads a connector's baseUrl from /api/v1/meta/connector/… (Studio, an agent, a QA runner) and sees 3000, while the flow it debugs actually calls the live port. This is the address mix-up #7538 was filed to end, now moved from dispatch to the metadata read. A runner that trusts /meta blames the wrong address or the sandbox, which is the expensive misdiagnosis #7538 records.

Reader who acts. The domain:devx seat: packages/cli/src/commands/dev.ts (whether an os dev artifact boot re-resolves env-derived connector config, or recompiles) and the header claim in examples/app-showcase/src/system/self-url.ts.

Measured

reach (public door): QA run QA run · release-18.2.0-manual-set (29/29) · 6679644a · 2026-10-25 · 25 PASS / 4 PARTIAL / 0 FAIL / 0 BLOCKED / 0 NOT-RUN #25817 at 6679644a, with OS_PORT=41302 exported on os dev: GET /api/v1/meta/connector/showcase_status_api answered baseUrl: http://127.0.0.1:3000, while the live connector_action reached 41302. It was not re-measured by the seat. Recorded in the os-dev report on PR qa(checklist): 18.2.0 sweep ledger edits — i18n, search, studio-authoring, ux-conventions, RUNNER #26109 (comment 6416286751, out_of_scope_findings[1]).
Reading of main 1bbb7bf4:
- examples/app-showcase/src/system/self-url.ts resolves SHOWCASE_SELF_URL, then OS_PORT/PORT, then the 3000 literal, at module evaluation, so a prebuilt dist/objectstack.json carries whatever the build-time environment gave.
- packages/cli/src/commands/dev.ts boots the artifact. The served metadata therefore carries the build-time value, while the dispatch path resolves at run time.

Expected

On an os dev boot, the connector baseUrl served by /meta equals the one dispatch uses, or self-url.ts stops claiming that the os dev value follows the live environment and says the served value is build-time.
A pin: an os dev boot with OS_PORT other than 3000 reads showcase_status_api's served baseUrl on that port.

Dedupe

Query on this repo (open and closed): "os dev serves build-time connector baseUrl 3000 while dispatch uses OS_PORT showcase_status_api" returned 9 hits. #7538 (closed) is the dispatch half this follows, and #26088 (open) is the docs port contradiction; neither is this defect.

⛔ Not a claim, ⛔ not a dispatch.

p2: on os dev with OS_PORT, /meta serves the build-time baseUrl while dispatch uses the live port, the Showcase REST connectors hard-wire baseUrl to http://127.0.0.1:3000, so self-ping flows fail fetch failed on any isolated instance — a port mismatch, not an egress block #7538 mix-up moved to the read side. Lane: packages/cli/src/commands/dev is cli-family, so domain:server under the lane merge. domain:devx is removed.

Took route (b) and did not propose route (a): `os dev` now compiles the cwd config into the artifact it serves, in its own environment, before the serve child starts. `--compile` defaults on, `--no-compile` keeps the old shortcut, and a pinned artifact is never rebuilt. The decision is the exported `devCompilesAtBoot`. After the fix both readers give 41302. `os start` and production `os serve` already agreed (41302) and are unchanged. Cost is one compile per dev start, 6.5 s on the showcase. Route (a) was not proposed because the artifact carries the value, not the env expression, so re-resolving it would need a new packages/spec form. The diff also touches files outside the claim's file surface: the cli.mdx `--compile` row (false otherwise), and one census entry in scripts/check-cli-test-child-env.mjs (the new test spawns the built bin/run.js).

Landed: os dev compiles the config under the boot's own environment by default, so with OS_PORT set the connector baseUrl that /meta serves and the one dispatch uses agree; --no-compile keeps the old shortcut, and a pinned artifact is never rebuilt.
Remains: none on this card. The two siblings the dev measured are their own cards, both claimed and now unblocked: cli/serve: os serve --dev with OS_PORT set still serves the build-time connector baseUrl from /meta while dispatch reaches the live port (the #26130 split on the serve door) #26242 (os serve --dev) and cli/dev: os dev -p N without OS_PORT leaves the showcase self URL at 3000, so its self-ping connector fails fetch failed and /meta serves :3000 (the #7538 symptom on the port-flag path) #26243 (os dev -p N without OS_PORT).
State: closed by the merge. The card thread is done.
