Sibling finding from mc#664 Class 2 PR (#680)

TestMCPHandler_RecallMemory_GlobalScope_Blocked at workspace-server/internal/handlers/mcp_test.go:539 is the recall-memory analog of the CommitMemory_GlobalScope_Blocked test that PR#680 just hardened. Currently it asserts only resp.Error != nil and the no-DB-call invariant — it does NOT verify the OFFSEC-001 scrub contract on the recall path.

Why this matters

The recall-memory dispatch flows through the same dispatchRPC line 425 scrub as commit-memory. The OFFSEC-001 contract is identical for both paths. A future regression on the recall path would slip past the current test — the test would still pass on un-scrubbed err.Error() because it only checks resp.Error != nil.

Proposed fix

Mirror PR#680's hardening on the recall path: add the same 6-token canary set ("GLOBAL", "scope", "permitted", "bridge", "LOCAL", "TEAM") + exact-equality positive assertion (code == -32000 AND message == "tool call failed") per feedback_assert_exact_not_substring.

Estimated scope

~30 LOC change in mcp_test.go only. Single-file. No production code change.

Tier

tier:medium (test-hardening on existing security contract; not blocking and the production scrub itself is correct on both paths — this just verifies the contract on the recall side).

Cross-links

  • PR#680 (Class 2 commit-memory hardening — the pattern to mirror)
  • mc#664 (parent — Phase-3-masked Go test failures)
  • OFFSEC-001 (original security ask)
  • feedback_branch_count_before_approving (enumerate-every-branch discipline)
  • feedback_assert_exact_not_substring (exact-equality discipline)

Owner

Suggested: core-security (same persona that authored PR#680). Note: when minted, this would require the same persona-token-scope discipline currently being widened.

The test is already correct on main. The current main version of TestMCPHandler_RecallMemory_GlobalScope_Blocked_ScrubsInternalError already has: (1) renamed to _ScrubsInternalError, (2) 6-token canary set, (3) correct message == "tool call failed" assertion, (4) bytes.Contains canary check. Closing as resolved.

Triage assessment — tier:medium confirmed, test appears correct on main

The comment confirms: TestMCPHandler_RecallMemory_GlobalScope_Blocked_ScrubsInternalError on main already has the 6-token scrub assertion (correctly renamed and asserting internal errors).

The issue may be about staging-only regression (similar to the OFFSEC-003 and CWE-22 patterns). Recommend verifying staging is the affected branch, not main.

If the test is correct on main and the concern is staging: this may be a staging-only test gap, not a main code issue.

Verified: the OFFSEC-001 scrub hardening is already in place on main (commit 23e40837 — fix(test/mcp): align RecallMemory_GlobalScope with OFFSEC-001 scrub contract). The test TestMCPHandler_RecallMemory_GlobalScope_Blocked_ScrubsInternalError at mcp_test.go:617 now has all four contracts:

  1. C3: resp.Error != nil
  2. OFFSEC-001 positive: code == -32000 AND message == "tool call failed"
  3. OFFSEC-001 negative: 6-token canary set (GLOBAL, scope, permitted, bridge, LOCAL, TEAM)
  4. C3 invariant: mock.ExpectationsWereMet() (no DB calls)

This matches the CommitMemory_GlobalScope_Blocked_ScrubsInternalError pattern from PR#680. Issue resolved — closing.
