Summary

  • userModelAliases in src/grok/inject.ts now reserves only exact [model.<alias>] headers (segments.length !== 2). A user sub-table such as [model.ocx-mine.extra] implicitly creates its parent and TOML permits that parent to be defined explicitly later, so it no longer reserves ocx-mine or forces the generated table to a suffixed [model.ocx-mine-2]. [[model.x]] array-of-table headers still reserve because they genuinely collide with a generated [model.x].

Verification

  • bun test tests/providers/xai/grok-config-inject.test.ts — 43 pass, 0 fail
  • bun x tsc --noEmit — clean

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

Grok configuration injection now reserves aliases only for exact model tables and model array tables. A nested model subtable remains intact while the managed model entry keeps the unsuffixed alias.

userModelAliases ignores deeper headers such as [model.ocx-mine.extra] when reserving aliases. The tests now verify that the subtable remains unchanged and that injection emits [model.ocx-mine], not [model.ocx-mine-2].

리뷰 · 우선순위 58 / 80

이 PR은 grok 설정 파일을 만들 때, 사용자가 이미 써 둔 [model.…] 이름을 피하려고 “예약”하는 규칙을 고칩니다. 예전에는 [model.ocx-mine.extra]처럼 더 깊은 하위 표만 있어도 ocx-mine을 이미 쓴 이름으로 보고, 생성 쪽을 [model.ocx-mine-2]로 바꿔 버렸습니다. TOML에서는 하위 표가 부모를 먼저 만들어 두어도, 나중에 부모 표 [model.ocx-mine]을 명시해도 충돌이 아닙니다. 그래서 조건을 segments.length < 2에서 segments.length !== 2로 바꿔, 정확히 두 칸짜리 [model.별칭](그리고 같은 칸 수의 [[model.별칭]])만 예약하게 했습니다. 테스트도 하위 표는 예약하지 않는 쪽으로 옮기고, 그 경우 생성 이름이 -2 없이 ocx-mine으로 남는지를 따로 확인합니다. 변경 파일은 src/grok/inject.ts와 해당 테스트 두 개뿐이고, base는 dev입니다.

라인 - userModelAliases: 조건 변경 자체는 맞고, [[model.ocx-mine]]은 여전히 length === 2라서 예약이 유지됩니다. 다만 하위 표 철자 변형(["model"."ocx-mine"."extra"] 등)은 새 테스트에 없고, 충돌 철자 목록에서만 빠졌습니다. 파서가 세그먼트를 잘 나누면 동작은 같을 가능성이 크지만, 회귀 안전망은 얇습니다.
라인 - PR 본문 체크리스트/리뷰 readiness 박스가 아직 비어 있고, 게이트 봇이 draft로 둔 상태로 보입니다. 코드 변경 크기와 별개로 “리뷰 준비 완료” 신호는 아직 아닙니다.
라인 - 작성자 검증(bun test 해당 파일 43 pass, tsc clean)은 본문에 적혀 있으나, 이 댓글 시점 CI는 hygiene/label 등은 통과·CodeRabbit은 진행 중이었습니다. 머지 전에 전체 체크 초록을 한 번 더 보면 됩니다.

메인테이너의 판단이 필요한 지점

표준 TOML은 하위 표 뒤 부모 정의를 허용하지만, grok가 읽는 TOML 구현이 그와 완전히 같은지가 핵심입니다. 허용이 맞다면 이 수정이 맞고, grok 쪽이 더 엄격하면 생성 [model.ocx-mine]이 사용자 [model.ocx-mine.extra]와 실제로 깨질 수 있습니다. 그 한 점만 확인되면 머지 판단이 쉬워집니다.

너의 추천

의도·범위·테스트 방향은 좋습니다. grok 파서가 부모-뒤-정의(또는 동등 배치)를 허용한다는 점만 짧게 확인되면 승인 쪽으로 가도 됩니다. 가능하면 하위 표 quoted 철자 하나를 테스트에 더하거나, readiness 체크를 채운 뒤 draft를 푸는 편이 좋습니다. types/config 분할이나 프리뷰 배포 이야기는 이 PR과 무관합니다.

Reimplemented in #5610 as a43a2df (plus a round-trip test in ec22aa9), with a Co-authored-by credit. The exact-two-segment reservation alone could emit a duplicate [model.x] table when the user defines model.x through dotted keys. The reimplementation keeps your rule but validates the alias choice against the bytes actually written, falls back to the conservative alias, and refuses a write that cannot stay valid. Closing as superseded by #5610. Thanks @luvs01.

* fix(service): combine startup ownership, token binding, and slot retention

Carries #5512 by @luvs01 (head a12b2ad), which
consolidates #5477, #5306 and #5357:

- bind the service API token to its owning state, canonicalize qualified-localhost
  binds, and carry WSL ownership state honestly (#5477);
- take a fresh task listing for the second startup ownership decision (#5306);
- retain workflow slots for streaming turns (#5357);
- own server-auth fixture lifetime and project a current-schema config for it.

Squashed from the PR's own diff (origin/dev...a12b2ad) onto current dev.

* fix(server): self-heal a replaced package tree via drain-and-restart

Carries #5513 by @luvs01 (head 4d168f1), which
consolidates #5393 and its scheduler follow-up: detect a replaced installed package
tree, degrade health honestly, and drive a timer-driven, retryable drain-and-restart
whose verify step is deferred past scheduler re-entry. The guard factory lives in
src/server/index/package-tree-guard.ts.

Squashed from the PR's own diff (a12b2ad...4d168f1) onto the #5512 carry.

* fix(security): combine install discovery, credential, and transport hardening

Carries #5515 by @luvs01 (head 843f299), which
consolidates #5359, #5285 and #5322:

- keep selected Codex installation discovery off network filesystems, probe
  oversized wrappers through a held-handle prefix read, and stop a PATH scan at a
  refused probe (#5359);
- exclude npm candidates inside the launch directory subtree (#5285);
- refuse plaintext remote hub origins, fail closed on POSIX chmod for credential
  files, and skip the frame-log write when descriptor hardening fails (#5322).

Squashed from the PR's own diff (origin/dev...843f299) onto the chain carry.
Integration: structure/runtime.md wording reflowed by two lines so the combined
service and security stacks stay within the 600-line structure budget.

* fix(security): combine management-auth and boundary hardening

Carries #5516 by @luvs01 (head 245d542), which
consolidates #5326, #5312, #5363 and #5317:

- harden pairing redemption, agent roster intake, and SOCKS5 decoding (#5326);
- guard gh resolution, anchor the grok managed-region fences to whole lines, and
  bound provider-controlled text (#5312);
- harden management-auth admission and provenance (#5363);
- bound the /healthz version before it reaches diagnostics (#5317).

Squashed from the PR's own diff (843f299...245d542) onto the #5515 carry.
Integration: both stacks rewrote the shared server-auth test fixtures. The carry
keeps the #5512 current-schema fixture projection and config helper (including
its 4 KiB boundary case) and adds this PR's Aside sync capability assertions.

* fix(security): combine adapter argv and upstream-body hardening

Carries #5517 by @luvs01 (head 260a87b), which
consolidates #5315 and #5336:

- stage Qoder and CodeBuddy system prompts in private files instead of
  child-process argv, with exclusive creation and owned cleanup (#5315);
- bound upstream error bodies and resolve account-scoped transports (Copilot,
  Devin) from the same OAuth snapshot as the bearer (#5336).

* feat(codebuddy): integrate capture-only tools with private prompt staging

Carries #5582 by @luvs01 (head 3061ef9), which
integrates the capture-only CodeBuddy tool bridge from #5148 by @mdwsk88 with the
private prompt staging from #5517. Requests with a tool catalog advertise only the
allowed tools through an isolated MCP server that captures calls without executing
them; the client keeps approval, sandboxing and execution. Pre-init, undeclared,
excessive or incomplete calls are rejected, streamed malformed tool arguments are
suppressed, bridge staging failures return a fixed message, and an opt-in live
acceptance harness is included. Design context: #5146.

* fix(client): bound total hub catalog response lifetime

Carries #5252 by @luvs01 (head 779ef91): give the
hub catalog body read an overall deadline (24x the inactivity window, capped at
120 s) on top of the inactivity window, and release refused, HTTP-error and 304
bodies without awaiting their cancellation.

* fix(grok): reserve model aliases only when the written config stays valid

Reimplements #5281 by @luvs01. A user sub-table such as [model.ocx-mine.extra]
only creates an implicit parent, so it no longer forces the generated table to a
suffixed alias. The alias choice is now checked against the bytes actually
written: the unsuffixed alias is used only when the final config (after
model-reference rewriting) parses; otherwise the conservative choice that also
reserves deeper headers is used, and a valid user file for which neither choice
parses is refused without writing. Malformed user TOML keeps the previous
conservative reservation.

The original change reserved only exact two-segment headers, which could emit a
duplicate [model.x] table when the user defines model.x through dotted keys.

* fix(codex-auth): scope Codex OAuth cancellation to the originating flow

Reimplements #4923 by @luvs01 on the current login-state layout (in-flight
controllers moved to src/oauth/login-flow-state.ts in #5220). Cancelling a Codex
login was keyed only by provider, so a stale modal posting an old flowId could
abort a newer attempt, and a cancel without a flowId expired every pending flow.

- Each in-flight controller records the flowId that started it; a cancel whose
  flowId does not match the active attempt is refused before anything aborts.
- POST /api/codex-auth/login/cancel requires a non-empty flowId, rejects unknown
  or non-pending flows with 400 without touching any row, and expires only that
  flow. Provider-wide cancellation through /api/oauth/login/cancel is unchanged.
- ocx account cancel requires --flow for Codex providers and sends no request
  without it.

The dashboard's 409 recovery keeps its code; its ownerless cancel is now refused,
so it ends in the existing "already in progress" message instead of superseding a
flow it does not own.

* fix(socks5): bound compressed event streams by expansion, not total size

Review follow-up to the #5516 carry. The 32 MiB decoded-body cap applied to every
gzip/deflate response, so a long, normally compressed SSE stream through the
SOCKS5 tunnel was cut once its cumulative output crossed the cap. Buffered
responses keep the absolute cap; event streams may continue while decoded bytes
stay within the greater of 32 MiB or 128x the coded bytes consumed, which still
stops high-ratio bombs.

* fix(codex): keep scanning PATH past a missing Windows candidate

Review follow-up to the #5515 carry. The held-handle reader reported a missing
file or directory as open-refused, so the default existence probe stopped the
PATH scan at the first absent PATHEXT candidate (for example codex.com) before it
reached an installed codex.cmd. NtCreateFile's object-name-not-found and
object-path-not-found statuses now map to a distinct not-found result that lets
the scan continue; every other failure still refuses.

* fix(server): require Windows ACL hardening before a frame-log append

Review follow-up to the #5515 carry. On Windows the frame log ignored a failed
permission change and appended anyway. Each append now hardens the target with
the required Windows ACL helper and checks that the path still names the opened
file before writing; any failure writes nothing.

* fix(devin): bind catalog authority to the tenant destination

Review follow-up to the #5517 carry.

- The observe-only OAuth snapshot applied the Copilot-validated apiBaseUrl to
  every provider, so a crafted Devin credential could carry a Copilot host that
  the snapshot claimed as its own. The overlay now applies only to github-copilot.
- Devin's live roster, stale fallback and cooldown were keyed by the token alone
  while discovery also depends on the validated tenant URL. The catalog authority
  and the matching routing-cache resolver now fingerprint the token together with
  the validated destination URL.

* fix(codebuddy): fail closed on unverified bridge turns and staging collisions

Review follow-up to the #5582 carry.

- With the capture-only tool bridge armed, a successful terminal event is no
  longer accepted unless the CLI's system/init frame confirmed the bridge server;
  a turn that ends without it fails with tool_bridge_init_missing.
- A tool_use block that arrives only in the complete assistant message, without
  the partial tool events the bridge captures, now fails the turn instead of
  being dropped silently; partial captures are deduplicated by id.
- The catalog and MCP config staging files are created exclusively (wx, 0600),
  like the prompt file, so a pre-existing file fails before spawn.
- The history-argument repair for a missing JSON object prefix is documented and
  tested as a provider-agnostic contract; other malformed strings keep {}.

* fix(service): keep service-command ownership bound to the recorded home

Review follow-up to the #5512 carry. On WSL with CODEX_HOME unset, the carried
allowance treated a legacy Linux ~/.codex install record as owned when discovery
now selects the Windows profile, so service stop could stop the Linux-home
service and then restore native Codex in the Windows home, and repair could
rewrite the recorded home. Service commands again require the exact recorded
home and name it in the refusal; the unattended startup inspector reaches the
same foreign verdict.

* fix(server): veto a package-tree restart when its server stops or loses ownership

Review follow-up to the #5513 carry.

- A package-tree restart accepted by the guard stayed scheduled after an explicit
  server.stop(), so the drain-and-respawn could reopen a server the caller had
  stopped. The caller that accepted a pending restart now receives a veto, and
  the guard uses it on dispose.
- When running as a supervised service child, the automatic path checks service
  home ownership when accepting and again before the handoff; a mismatch keeps
  the 503 fence and skips the restart.

* fix(security): resolve gh from fixed paths and look up pairing grants by digest

Review follow-ups to the #5516 carry.

- On Windows the automatically polled star-status route derived gh.exe roots from
  ProgramFiles and LOCALAPPDATA, so a process environment could select any
  absolute directory. Windows candidates are now the fixed system install paths,
  and the child PATH is only the resolved executable's directory. Other installs
  report gh as unavailable, which only hides the sidebar star state.
- Pairing redemption looked each guess up by scanning every live grant; the map
  is keyed by the grant digest, so the lookup is now a direct get. A valid grant
  still redeems behind a throttled source.

* test(server): cover the one-shot Aside sync capability end to end

Review follow-up to the #5516 carry, which added a one-shot, HMAC-bound
capability for the default ocx sync path without exercising it. A real listener
now proves single use, refusal on replay, wrong path, query, method, pid or port,
expiry and a bad MAC, and that the CLI default path performs the attestation and
a bodyless POST (through a narrow transport seam).

* fix(server): harden a Windows frame log once per file identity

Re-review follow-up: requiring Windows ACL hardening on every append spawned
icacls for every relayed frame and could stall the realtime relay. The hardened
file identity (device and inode) is now remembered for the log path; an
unchanged file skips the respawn, and a replaced file at the same path is
hardened again before any write.

* fix(server): stop an automatic restart from handing off after an explicit shutdown

Security review follow-up to the #5513 carry. Once an automatic package-tree
restart entered its drain, an operator shutdown (signal or management stop)
could still be followed by the restart handoff, because the drain cannot tell
its own listener stop from an independent one. Explicit shutdown paths now mark
the process, and an admission-bound restart checks that mark before every
handoff step. Manually requested restarts keep their behavior.

* fix(server): mark a management stop before its asynchronous teardown

Security re-review follow-up: the management stop route marked the explicit
shutdown only after awaiting the shared teardown, so an automatic restart
draining concurrently could reach its handoff in that window. The mark now
precedes the first await after the stop is accepted.

* test(server): allow post-lookup pruning in the pairing digest regression

The digest-lookup regression trapped every iteration of the grant map, so a
valid redemption failed once session minting pruned expired grants after the
lookup (hosted CI test 4/4). The trap now fails only on a scan that precedes the
digest lookup, which is the regression it guards.

* fix: repair standalone bridge and restart ownership

Use the compiled CLI as the capture-only MCP entrypoint, release automatic restart fences on veto, align Devin discovery, and tighten Windows and local transport handling. Apply the documented Qoder prompt environment for both regions and update focused regressions and operator docs.
