Summary

On a hub, ocx hub invite printed only Minting a pairing code failed (rejected). when the running hub refused the browser origin the code is bound to. The CLI picks that origin from config.json on disk, but the running hub checks it against the corsAllowOrigins and hub.managementPublicOrigin it loaded at startup. An allow-list edited after the hub started kept failing, and nothing said which origin, which setting, or that a restart was needed (#8319).

Before:

Minting a pairing code failed (rejected).

After, when the hub's grant route refuses the origin (its plain 403):

Minting a pairing code failed (origin-refused).
The running hub refused to mint a code bound to browser origin http://localhost:10100. It admits only hub.managementPublicOrigin and the corsAllowOrigins entries it is running with, which can predate a recent 'ocx config set'. If you changed either, restart the hub and invite again.
Restart to apply: ocx restart (OpenCodex Desktop supervises the replacement).

The pairing client used to map every non-2xx answer to rejected. It now reports the grant route's plain 403 GUI pairing grant refused (no code) as origin-refused, the only case an allow-list edit or a restart can cure, and its 429 as rate-limited, which says the hub is limiting new codes (eight a minute, and a cap on unused ones) and to wait for earlier codes to be used or expire. A coded refusal, a capability refusal and a 5xx stay rejected and print no setting or restart advice. No response body is ever surfaced.

The restart line reuses hubDisableRestartHint(), so it names the Desktop, service, or manual restart that fits the install. Other failure reasons (attestation, transport, rejected, …) print no restart line.

ocx config set now adds a human line for hub, hub.managementPublicOrigin and hub.managementIngress (live topology, applied only at start) and for corsAllowOrigins (the running proxy may keep its previous list until it restarts, because only a later live save adopts the file). It appears only when the value actually changed. --json output keeps its {ok, path, value} shape. Other keys print nothing new, so the note never claims a restart that isn't needed.

The issue also suggested letting the local CLI bypass the browser-origin check. That would change who a hub admits for pairing, so it is not in this PR (see the triage comment on #8319).

The remote-hub guide describes the restart requirement and the new message.

Closes #8319

Verification

  • Fail-first on origin/dev: the new tests/cli/hub-invite.test.ts case failed (Received: "Minting a pairing code failed (rejected)."), and the new tests/cli/cli-config-command.test.ts case failed (Received: "Set corsAllowOrigins.\n"). Both pass with the fix.
  • Review round 1 found that a 429 or 5xx would also blame the allow-list. New fail-first cases in tests/gui/gui-pair-client.test.ts (429 → rate-limited, plain 403 → origin-refused, coded or capability 403 and 500 → rejected) and tests/cli/hub-invite.test.ts (rate limit and generic refusal never mention the allow-list or a restart).
  • bun test tests/gui/gui-pair-client.test.ts tests/cli/hub-invite.test.ts tests/cli/cli-config-command.test.ts: 59 pass, 0 fail (the config test spawns the CLI as a subprocess, so it was run explicitly).
  • bun run test:changed: 1137 tests, 1 skip, 0 fail.
  • bun run typecheck, bun run privacy:scan, bun run structure:check: pass.
  • Layout, file-size ratchet, Lab boundary, and structure guards (tests/test-layout*.test.ts, tests/ci-workflows/file-size-ratchet.test.ts, tests/lab/core-lab-boundary.test.ts, tests/ci-workflows/structure-ssot.test.ts): 114 pass.
  • Review: two hyds/deepseek rounds (round 1 FAIL → 429/5xx misclassification and wording fixed; fresh final PASS at 4787e94, delta PASS at 6499411), security review PASS at b37acb3 and on the later delta, plus the CodeRabbit follow-ups (rate-limit wording for both 429 causes, ingress note, nested-path tests, heuristic documented).
  • NOT RUN: full bun run test (the change is limited to two CLI message paths covered above; CI shards cover the rest). Not exercised against a live Windows Desktop hub.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Walkthrough

The CLI now prints restart notices for committed changes to selected configuration paths. Pairing grant responses distinguish origin refusals and rate limits from other rejections. Hub invite errors provide corresponding guidance, and the remote hub guide documents startup-loaded settings and troubleshooting steps.

Changes: Hub invite restart guidance

Layer / File(s) Summary
Configuration restart notices
src/cli/config-command.ts, tests/cli/cli-config-command.test.ts
Committed changes to corsAllowOrigins or selected hub paths append restart notices. Tests cover changed and unchanged values, an unrelated setting, and JSON output.
Pairing refusal classification
src/cli/gui-pair-client.ts, tests/gui/gui-pair-client.test.ts, tests/gui/gui-pair-http.test.ts
HTTP 429 responses map to rate-limited. A specific uncoded HTTP 403 response maps to origin-refused; other tested refusals map to rejected.
Invite refusal guidance
src/cli/hub.ts, tests/cli/hub-invite.test.ts, docs-site/src/content/docs/guides/remote-hub.md
Origin refusals identify the relevant settings and provide a restart hint. Rate-limit messages explain the limits and advise waiting for earlier codes to be used or expire. Tests and the guide cover these messages and other refusal cases.

Explanation

Issue #8319 accepts either a working local invite or an error that identifies the rejected origin, relevant settings, and restart remedy. src/cli/gui-pair-client.ts classifies the plain, uncoded grant-route 403 as origin-refused and the 429 as rate-limited; other refusals remain rejected. src/cli/hub.ts (runInvite, around lines 338–351) prints the bound browser origin, names hub.managementPublicOrigin and corsAllowOrigins, and gives a restart hint for origin-refused only. It gives separate wait guidance for rate limits and does not expose response bodies. src/cli/config-command.ts (startupOnlyConfigNotes, around lines 145–163; committed mutation output around lines 318–324) adds notes for changed relevant settings, while preserving JSON output and omitting notes for other keys or unchanged values. Tests in tests/gui/gui-pair-client.test.ts, tests/cli/hub-invite.test.ts, and tests/cli/cli-config-command.test.ts cover these behaviors. docs-site/src/content/docs/guides/remote-hub.md documents the restart requirement. The follow-up in tests/gui/gui-pair-http.test.ts recognizes the new failure classes.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #8319. Failure classification prevents rate limits, coded refusals, and server errors from receiving incorrect origin or restart advice. Config notes address the startup or reload behavior relevant to the invite failure. The guide and tests support those changes. The additional gui-pair-http test update covers the new CLI failure labels. The PR does not change pairing admission or add the suggested local-CLI bypass.

Full details: Docstring Coverage

Explanation

Docstring coverage is 42.86% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 7 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Maintainer judgment

  • Value: a hub operator who adds corsAllowOrigins after start no longer retries a refused invite blind. The error names the origin, both settings, and the restart command for this install.
  • UX change scope: CLI text only. The first stderr line is unchanged, and two lines follow it only for the rejected reason. ocx config set adds one human line for three startup-only keys, only when the value changed.
  • Existing users: no behavior change. Pairing admission, --json payloads, and exit codes are unchanged. Existing hub-invite and config-command tests pass unchanged.
  • Windows: the reporter's platform. The restart hint comes from hubDisableRestartHint(), which already distinguishes Desktop supervision, a service, and a manual start. No path or shell differences.
  • Verification scope: fail-first tests for both messages, focused suites, test:changed, typecheck, privacy, structure, layout/ratchet/Lab guards.
  • NOT RUN: full bun run test; a live Windows Desktop hub.

Distinguish rate limits from origin refusals.

After eight grants in 60 seconds, a further invite can receive HTTP 429. gui-pair-client.ts maps it to rejected, so hub.ts reports an origin refusal and suggests a restart instead of a retry.

Preserve a distinct rate-limit reason and show retry guidance. Return an explicit origin-refusal code from the server and show origin guidance only for that code; keep other rejections generic. Update the invite and client tests and the rejected-invite guidance in docs-site/src/content/docs/guides/remote-hub.md.

Comment thread tests/cli/cli-config-command.test.ts Resolved
ocx hub invite printed only "Minting a pairing code failed (rejected)." when the
running hub refused the bound browser origin. The CLI picks that origin from the
config on disk, while the hub checks it against the corsAllowOrigins and
hub.managementPublicOrigin it loaded at startup, so an allow-list edited since
then kept failing with nothing to act on.

A rejected mint now names the bound origin, the two settings, and the
supervisor-aware restart command. ocx config set prints a restart note for
corsAllowOrigins, hub and hub.managementPublicOrigin, the keys a running proxy
reads only at startup; the --json payload is unchanged.

Closes #8319
Review of #8495: the pairing client mapped every non-2xx answer to "rejected",
so a 429 from the per-minute grant limit, a capability 403 or a 5xx also told
the operator to edit corsAllowOrigins and restart a healthy hub. The client now
reports the grant route's plain 403 as origin-refused and its 429 as
rate-limited; everything else stays rejected. ocx hub invite prints the origin
and restart guidance only for origin-refused, and a wait-a-minute line for
rate-limited. The corsAllowOrigins note in ocx config set now says the running
proxy may keep the previous list until restart, since a later live save can
adopt it; hub keys stay start-only (LIVE_TOPOLOGY_KEYS).

The rate-limit message is inaccurate when the 128-outstanding-grant cap triggers the 429.

createGuiPairingGrant in src/server/gui-session.ts:255-283 throws GuiPairingGrantRateLimitError for two causes. One is more than 8 grants in 60 seconds. The other is pairingGrants.size >= GUI_PAIRING_GRANT_LIMIT (128). The route sends both as 429, and refusalReason maps both to rate-limited. In the second case, waiting one minute may not help, because the cap is not time-windowed. Unredeemed grants must expire first. The message "wait a minute" can then mislead the operator.

Use wording that fits both causes. For example: "The hub is limiting new pairing codes (a per-minute limit and a cap on unused codes). Wait for earlier codes to expire, then invite again." Update the docs line in remote-hub.md and the wait a minute assertion in tests/cli/hub-invite.test.ts to match.

Review follow-ups on #8495 (CodeRabbit): the grant route's 429 covers both the
per-minute limit and the cap on unused codes, so the advice now says to wait
for earlier codes to be used or expire. ocx config set also notes a restart for
hub.managementIngress, which the hub binds at start, with tests for the nested
hub paths. The origin-refused mapping documents that it is a heuristic.

Include the one-minute wait in the rate-limit guidance.

If eight codes are created and used within one minute, the next invite is still rate-limited. consumeGrantRateSlot tracks creation time independently of whether codes were used (src/server/gui-session.ts, Lines 255–294). The current message can therefore suggest retrying immediately, but the retry will fail.

Tell users to wait at least one minute before retrying and, if the unused-code cap applies, to also wait for earlier codes to be used or expire. Add an assertion for both instructions in tests/cli/hub-invite.test.ts.
