Summary

• Log explicit warnings when memory.qmd.scope denies a memory_search request.
• Include derived channel/chatType/session in the warning payload for quick debugging.
• Add regression tests for the deny path.

Why

Fixes #10191. Scope-denied searches were silently returning empty results, which looked like missing memory instead of policy gating.

Changes

• src/memory/qmd-manager.ts
  • Added logScopeDenied(sessionKey) helper.
  • Emit warning when scope blocks a search.
• src/memory/qmd-manager.test.ts
  • Mocked logger and added logs when qmd scope denies search test.
  • Asserted no query subprocess is spawned in the deny path.
• docs/concepts/memory.md
  • Documented scope-deny warning behavior.
• CHANGELOG.md
  • Added #10191 fix note.

Validation

• pnpm test src/memory/qmd-manager.test.ts
• pnpm check

Greptile Overview

Greptile Summary

This PR adds explicit warning logs when memory.qmd.scope denies a memory_search request, including derived channel, chatType, and the session key in the log message to make scope-gated empty results easier to diagnose. It also adds a regression test that verifies the deny path returns [], emits the warning, and does not spawn the QMD query subprocess.

The behavioral change is localized to QmdMemoryManager.search() and uses the existing session-key parsing helpers (deriveChannelFromKey / deriveChatTypeFromKey) to populate the warning payload. Documentation and changelog are updated to reflect the new warning behavior.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk.
• Change is small and localized (adds a warning + test for an existing deny path) and does not alter allowed search behavior; the new test covers the main regression (deny returns empty and avoids spawning QMD).
• No files require special attention
