The previous commits in this branch inadvertently dropped the prominent
ROADMAP-refactor-in-progress warning from AGENTS.md. That change is
unrelated to fixing the team_send_message ambiguous delivery loss and
should not ride along with this PR.
This commit restores the banner verbatim from the dev branch tip.
Grok model IDs (e.g. `grok-4.3`, `grok-3-mini`) were missing from `HEURISTIC_MODEL_FAMILY_REGISTRY`, so `resolveCompatibleModelSettings` returned an "unknown family" result for them.
The `chat.params` hook treats unknown families as "no reasoning support" and deletes `output.options.reasoningEffort` before the request leaves the plugin, so users routing Grok via OpenAI-compatible endpoints never saw their reasoning effort forwarded — even with `forceReasoning: true`.
Add a `grok` family entry that includes any model ID containing "grok", exposes `low | medium | high` variants, and sets `reasoningEfforts` so the heuristic surfaces the same capability flag used by the `chat.params` hook. Extend the family table-driven test in `model-settings-compatibility.test.ts` to cover `grok-4.3`.
Include Vertex Anthropic in the assistant-tail prefill guard after Cubic flagged the strict provider check. Keep the non-Anthropic opencode negative control covered by tests.
Plan: plans/fix-anthropic-assistant-prefill-tail.md
Tighten the assistant-tail repair after review so only the Anthropic provider is treated as prefill-rejecting, and so assistant-tail model metadata is evaluated independently from the last user model.
Add regression coverage for an allowed user model followed by a rejecting Anthropic assistant tail, plus a non-Anthropic provider carrying a Claude-looking model id.
Plan: plans/fix-anthropic-assistant-prefill-tail.md
Claude Opus 4.7 rejects requests whose final message is an assistant turn, because Anthropic treats that as unsupported assistant prefill. Add a transform guard that appends the existing synthetic user recovery turn only for Anthropic prefill-rejecting model IDs, while preserving assistant-prefill behavior for supported and unknown models.
Tests cover Opus 4.7, Opus 4.6 assistant metadata fallback, direct Sonnet 4.6 model fields, allowed OpenAI/Sonnet 4.5 tails, missing metadata, and compaction continuation compatibility.

ensureBaseDirs unconditionally called chmod(baseDir, 0o700) on every startup
and on every team_create. On filesystems where the OS rejects chmod for the
directory (network mounts, SIP-protected locations, non-owner cases on macOS
shared by multiple GUI users), the call raises EPERM and the entire team-mode
init aborts:
[team-mode] init failed: EPERM: operation not permitted, chmod '/Users/<u>/.omo'
Wrap chmod through a small safeChmod helper that converts EPERM, ENOTSUP, and
EINVAL into a single warning log and continues. mkdir already creates new
directories with mode 0o700, and the existing post-creation stat-guard remains
in place for the case where the directory pre-exists with a different mode and
chmod is permitted, so the security envelope on supported filesystems is
unchanged. All other error codes (ENOENT, EACCES, etc.) still propagate.
Regression test mocks node:fs/promises.chmod to throw EPERM and asserts that
ensureBaseDirs completes successfully and emits exactly the documented warning.
Require the latest assistant tool-wait turn itself to be stale before a shouldReply parent wake can bypass tool-call deferral. This prevents an all-complete background wake from forking a second parent prompt loop when OpenCode has repaired the tail to a synthetic user message.
