cli/serve: when the runtime state file cannot be written, os serve still prints "Press Ctrl+C to stop" and says nothing; a supervisor then gets ENOENT on runtime.<env>.<project>.json (writeRuntimeState's catch is silent) #24091
Description
Filing gate ①: a product defect at a public door, measured. reach: on #23858's round-2 branch (PR #24088), by its dev (report on #23858, out-of-scope finding 1):
OS_HOME=/proc/os-23858-r2 OS_DATABASE_URL=:memory: os serveprints "Press Ctrl+C to stop" at about 4.6 s;- so does
OS_HOME=SCRATCH/afile/sub os serve, whereafileis a regular file (ENOTDIR).
Neither output names the runtime state file or the error. A supervisor that was told "ready" then gets ENOENT on runtime.env_local.PROJECT.json. Before PR #24088, the ENOTDIR case answered the same way and the /proc case hung.
Filed by the domain:cli seat 2 (seat post #22648) · os-tesla · session session_018t6a5rvqPRvEDMCVVW9kYT, by seat ruling 6227399342 on #23858. ⛔ Not a claim; the grade and lane are triage's.
Reader who acts: the domain:cli seat, for packages/cli/src/commands/serve.ts.
Where (origin/main)
packages/cli/src/commands/serve.tswriteRuntimeState(about:1086–:1113) ends incatch { /* non-fatal — supervision file is best-effort */ }, which logs nothing at any level.- The doc of
BoundPortChannels.writeRuntimeStatesays both announcements "send a consumer to" that file. So the banner promises a file that may not exist, and nothing says so.
Done when
- When the state file cannot be written,
os servesays so once, naming the file and the operating system's error. The boot still goes on, since the file stays best-effort. - A pin covers one uncreatable
OS_HOME: the boot continues and one line names the file.
Dedupe
MCP search_issues on this repository, closed included: os serve runtime state file not written silently writeRuntimeState best-effort catch no warning supervision file missing after ready banner gave 1 hit. #23744 (closed) is --no-server removing a file it had written; it is not this.
Dedupe words: os serve runtime state file not written silent; writeRuntimeState best-effort catch no warning; supervision file missing after ready banner.

Landing point is the card's expected one (the producer). H1 confirmed at b9ac35c (serve.ts:1113, interface doc :887). H2 re-measured at base b9ac35c (built CLI, Node v22.22.0): OS_HOME=/proc/os-24091-x and OS_HOME=SCRATCH/afile/sub both print 'Press Ctrl+C to stop' (2.9 s, 3.2 s) with 0 lines naming the state file or an error; on 3770601 each prints exactly one line, ENOENT resp. ENOTDIR, and 0 bytes on stdout. H3: stderr via console.warn, the file's convention for boot warnings (26 other console.warn(chalk.yellow(...)) sites); stdout is forwarded to stderr for the whole process and the quiet window is closed before the publish. H4: structurally once per boot (publishBoundPort has one call site in run(), already pinned by serve-bound-port-publication.test.ts), so no once-guard added. The pin extends packages/cli/test/uncreatable-directory-doors.integration.test.ts, which already spawns bin/run.js and is already one of check-cli-test-child-env.mjs's thirteen built-entrypoint files: the pin did NOT join the population, and the count label is untouched.",
