Ports the codex-rules transcript-aware dedup strategy: when a session cache is fresh (process restart or compaction-cleared cache), the injector now scans prior tool outputs for the `[Rule: <relativePath>]` banner and pre-populates the cache so duplicate rule injections are suppressed even when the persistent JSON has been lost. Hydration runs at most once per session per process, fails open on transport errors, and is short-circuited when the same banner reappears.

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.

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.
Tests:
- bun test src/features/background-agent/parent-wake-user-message-race.test.ts src/features/background-agent/task-completion-cleanup.test.ts src/hooks/shared/prompt-async-gate.test.ts src/shared/prompt-async-route-audit.test.ts --bail
- bun run typecheck
- bun test
Keep the built-in lsp MCP registered even when the submodule CLI artifact is missing.
The fallback command initializes the lsp-tools-mcp submodule, prefers the source CLI without dirtying the checkout with dist output, and keeps npm build as a last resort when Bun cannot run the source entrypoint.
Plan: plans/fix-lsp-mcp-missing-cli.md
When OpenCode reports the original assistant error after a fallback retry has already been accepted, keep waiting for the pending fallback model instead of clearing the awaiting flag.
This prevents a duplicate stale session.error from advancing the fallback chain and dispatching a second assistant retry prompt.
