…e writes Address PR #56 review findings on the rules-channel system prompt: - never force-append "project" to an explicitly configured settingSources (deliberate hardening opt-out); degrade to inline "message" delivery with a one-time warning instead - wrap the rule write in try/catch: a failed write (read-only checkout) degrades to "message" mode for the turn rather than failing it - add a generated-by sentinel to opencode.mdc frontmatter; a user-owned (sentinel-less) file is never overwritten or deleted - thread one canonical cwd through the provider options and dispose so write and cleanup can't diverge and orphan the rule file - make .cursor/rules/.gitignore ignore itself - skip the rewrite when the rule content is unchanged (no sync fs write on the stream hot path)

Summary
.cursor/rules/opencode.mdc(alwaysApply: true) and loaded via theprojectsettings layer — so opencode keeps control without being flagged.systemPromptprovider option:"rules"(default),"message"(legacy inline, back-comat),"omit". Rules load from disk atAgent.create, so no sidecar/RPC changes.disposeremoves the generated rule (best-effort). Session reuse is unaffected (fingerprint reads the prompt, not the forwarded message).Test Plan
