What

Rewrites TestMCPHandler_CommitMemory_GlobalScope_Blocked (now ..._ScrubsInternalError) in workspace-server/internal/handlers/mcp_test.go so that it asserts the OFFSEC-001 scrub-works contract rather than the (now-scrubbed) internal error string.

Single-file change. No production code touched.

Why

mc#664 (Platform (Go) red on main) decomposes into:

• Class 1 — 4 TestExecuteDelegation_* failures (parallel dispatch to core-be)
• Class 2 — this test (closed by this PR)

Class 2 root cause: commit 7d1a189f (2026-05-10, OFFSEC-001 / #259 hardening) replaced the third err.Error() leak in mcp.go dispatchRPC with the constant "tool call failed", logging the real error server-side only. The existing test at mcp_test.go:432 asserted:

if resp.Error != nil && !bytes.Contains([]byte(resp.Error.Message), []byte("GLOBAL")) {
    t.Errorf("error message should mention GLOBAL, got: %s", resp.Error.Message)
}

— i.e. that the client-visible message CONTAINED the internal text "GLOBAL scope is not permitted via the MCP bridge — use LOCAL or TEAM". Post-scrub that substring is no longer there (correctly), so the test went red. PR #665 has been masking this with continue-on-error as an interim measure; this PR is the proper Class-2 fix.

Wrong fix would be: un-scrub mcp.go to restore err.Error() in the wire response. That defeats the OFFSEC-001 hardening that was applied uniformly across 22 sibling files in PRs #1193 / #1206 / #1219 / #168.

Right fix (this PR): flip the assertion so the test FAILS if the scrub regresses and PASSES iff the scrubbed constant reaches the client.

What the new test asserts

Matching the canonical OFFSEC-001 test style already in this file (mcp_test.go lines 1031–1149):

1. HTTP 200 (JSON-RPC errors return 200 with error body — only malformed envelope JSON returns 400)
2. resp.Error != nil (C3 — handler reports an error)
3. Exact-equality positive assertions (per feedback_assert_exact_not_substring):
   • resp.Error.Code == -32000 (server-error / dispatch-failure code)
   • resp.Error.Message == "tool call failed" (OFFSEC-001 constant)
4. Negative scrub canaries — six substrings from the production-internal error string ("GLOBAL", "scope", "permitted", "bridge", "LOCAL", "TEAM") must NOT appear in the client-visible error.message. If ANY leaks, the canary fires.
5. C3 invariant preserved — mock.ExpectationsWereMet() ensures the handler short-circuits before any DB call.
6. Renamed ..._Blocked → ..._Blocked_ScrubsInternalError so the contract is visible in failure output and at the call site.

Verification

Phase 4 local — falsified both ways:

Positive (against current main with 7d1a189f scrub in place):

$ go test -run TestMCPHandler_CommitMemory_GlobalScope_Blocked_ScrubsInternalError ./internal/handlers/
ok  github.com/Molecule-AI/molecule-monorepo/platform/internal/handlers   0.515s   PASS

Falsification (temporarily reverted line 427 of mcp.go to Message: err.Error()):

• Positive constant-equality assertion FAILED (got the raw internal string)
• All six negative-token canaries FIRED simultaneously
• Test correctly fails ⇒ proves it actually verifies the contract, not just shape

Other TestMCPHandler_* tests continue to pass. The 4 TestExecuteDelegation_* failures observed when running the full handlers/ package pre-exist on origin/main and are Class 1 (core-be's parallel work in flight) — not touched by this PR.

Phase 4 CI: With Class 1 fixed in parallel by core-be, CI / Platform (Go) should be all-green on main once both PRs merge, allowing PR #665's continue-on-error mask to be reverted as a Layer 2 follow-up (separate from this Layer 1 PR).

Tier

tier:high — this is the contract test that guards OFFSEC-001 scrub on the commit_memory / GLOBAL-scope dispatch path. The previous weak assertion is exactly what allowed the internal error string to silently flow back to clients on this surface before #259 was identified; ratcheting it tight closes that class.

Brief-falsification log

• Brief halt-condition "If reading of 7d1a189f differs from this brief's account: STOP" — confirmed identical (3rd diff hunk, line 425 in pre-patch mcp.go, dispatchRPC tool-call branch, replaces err.Error() with "tool call failed", adds server-side log.Printf).
• Brief halt-condition "If mcp_test.go line 433 has been modified since this brief was written: STOP" — confirmed unchanged (line 432–434 exact text matches brief).
• Brief widen-scope check "look for sibling tests with the same anti-pattern" — found ONE sibling: TestMCPHandler_RecallMemory_GlobalScope_Blocked (mcp_test.go:539). It only asserts resp.Error != nil, so it is NOT broken by the scrub, but it also doesn't verify the scrub. Recommending a follow-up to strengthen it (and any recall_memory_v2 path) in a separate single-purpose PR. NOT addressed here per the brief's "1-2 siblings or report" discipline. See sibling-finding section below for filing.

Sibling finding worth filing (NOT addressed here)

TestMCPHandler_RecallMemory_GlobalScope_Blocked at mcp_test.go:539 is the recall-memory analog of the rewritten test. It currently asserts only resp.Error != nil and the C3 no-DB-call invariant — it does NOT verify the OFFSEC-001 scrub contract on the recall path. The recall-memory dispatch goes through the same dispatchRPC line 425 scrub, so the contract is the same. A regression on the recall path would slip past this test today. Recommend a follow-up PR (same pattern, ~30 lines, tier:medium) to mirror the contract assertions on the recall side.

test(mcp): rewrite GlobalScope_Blocked to assert OFFSEC-001 scrub contract (mc#664 Class 2) ... 394d8b7520

Background — chain of defects
-----------------------------
mc#664 (Platform (Go) CI red) decomposes into:
  • Class 1 — 4 TestExecuteDelegation_* failures (parallel dispatch to core-be)
  • Class 2 — TestMCPHandler_CommitMemory_GlobalScope_Blocked (this PR)

Class 2 root cause: commit 7d1a189f (2026-05-10) hardened mcp.go to scrub
err.Error() out of the JSON-RPC error.message returned to the client,
replacing the third leak (the dispatchRPC tool-call branch, line ~427)
with the constant string "tool call failed". The internal error is now
log.Printf'd server-side only.

The existing test at mcp_test.go:432 asserted that the client-visible
message CONTAINED the substring "GLOBAL" — which was exactly the
internal err.Error() text the 7d1a189f scrub now removes. So the test
had silently flipped from "verifies behaviour" to "verifies the bug",
and once the scrub landed the test went red. PR #665 has been masking
this red via continue-on-error as an interim measure; this PR is the
proper fix for Class 2.

Wrong fix
---------
Un-scrub mcp.go (i.e. restore err.Error() into the client-facing
message). This would re-open OFFSEC-001 / #259 and defeat the security
hardening that was applied uniformly across 22 sibling files in
PRs #1193 / #1206 / #1219 / #168.

Right fix (this PR)
-------------------
Rewrite the test so it asserts the OFFSEC-001 scrub-works contract
on this very code path, matching the same style used by the four
canonical OFFSEC-001 tests already in this file (lines 1031–1149):

  • exact-equality on resp.Error.Code (-32000)
  • exact-equality on resp.Error.Message ("tool call failed")
  • negative-substring canaries on six tokens from the production-internal
    error string ("GLOBAL", "scope", "permitted", "bridge", "LOCAL", "TEAM")
    — if ANY leaks through to the client, the scrub has regressed and the
    test fires immediately
  • C3 invariant preserved (no DB calls — handler short-circuits)
  • Test renamed to _ScrubsInternalError so the contract is visible at
    the call site / in failure output

Per feedback_assert_exact_not_substring: the positive assertion uses
exact-equality (`!= "tool call failed"`) rather than substring-match,
so any future mutation of the constant breaks the test loudly.

Verification (local, falsified both ways)
-----------------------------------------
  Positive: against current main (7d1a189f scrub in place)
    $ go test -run TestMCPHandler_CommitMemory_GlobalScope_Blocked_ScrubsInternalError
    ok      .../internal/handlers   0.515s  PASS

  Falsification: temporarily reverted line 427 of mcp.go to
  `Message: err.Error()`, ran the test → all positive assertions failed
  AND all six leaked-token canaries fired (proves the test really does
  guard the contract, not just shape).

All other TestMCPHandler_* tests continue to pass. The four
TestExecuteDelegation_* failures observed in the full handlers/
package run pre-exist on origin/main and are Class 1 (core-be's
parallel work) — not touched here.

Tier
----
tier:high — this is the security-hardening contract test for the
OFFSEC-001 scrub. A weak version of this assertion is what allowed
the original gap on the GLOBAL-scope path to go unnoticed for so long.

Brief-falsification log
-----------------------
  • Brief halt-condition: "If reading of 7d1a189f differs from this
    brief's account: STOP" — confirmed identical (3rd hunk, line 425 in
    pre-patch mcp.go, dispatchRPC tool-call branch, scrubs err.Error()
    → "tool call failed", logs server-side).
  • Brief halt-condition: "If mcp_test.go line 433 has been modified
    since this brief was written: STOP" — confirmed unchanged
    (line 432–434 exact text matches brief description).
  • Brief widen-scope check: searched for sibling tests with the same
    anti-pattern (assert internal err.Error() content on the OFFSEC
    code path). Findings:
      – TestMCPHandler_RecallMemory_GlobalScope_Blocked (line 539)
        asserts `resp.Error != nil` only; does NOT assert on
        "GLOBAL"-substring, so it isn't broken by the scrub. BUT it
        also doesn't verify the scrub-works contract — a future
        regression would slip past it. Recommending a follow-up to
        strengthen it (and the corresponding RecallMemory v2 path,
        if any) in a separate single-purpose PR rather than widening
        scope here. NOT addressed in this PR per the brief's
        "1-2 siblings or report" discipline.
  • OFFSEC-001 issue lookup: 22 files were touched by the sibling
    scrub PRs (#1193 / #1206 / #1219 / #168). This PR addresses ONE
    test that was asserting against the now-scrubbed surface. No
    other red-on-main tests are believed to share this anti-pattern
    in mcp_test.go (grep verified).

Five-Axis peer review — core-be persona (engineer-tier, NON-author / NON-PR-creator)

Reviewing head 394d8b752022914d5a54b8c8c1e9fe3e86065bd5 against main@b46227020173f018f5a73ff28e3bd2e9e7731a5a.

Verdict: APPROVE — zero Critical, zero Required. Two Optional + two FYI follow-ups noted below; none block merge.

---

Phase-1 grounding (cross-checked against source, not just brief)

• Production scrub site verified: workspace-server/internal/handlers/mcp.go:427 reads base.Error = &mcpRPCError{Code: -32000, Message: "tool call failed"} with server-side log.Printf on line 426. Matches the PR body's account of commit 7d1a189f exactly.
• Internal error string verified: workspace-server/internal/handlers/mcp_tools.go:426 is fmt.Errorf("GLOBAL scope is not permitted via the MCP bridge — use LOCAL or TEAM") — every one of the six negative-token canaries (GLOBAL, scope, permitted, bridge, LOCAL, TEAM) is a real substring of that internal string.
• Canonical sibling style verified at mcp_test.go:1088–1180 (..._MalformedJSON_ReturnsConstantParseError, ..._InvalidParams_ReturnsConstantMessage, ..._UnknownTool_ReturnsConstantMessage). The new test mirrors that style precisely.
• CI status on head: Handlers Postgres Integration = success in 4m36s (the actual go-test job). CI / Platform (Go) pending on required-conditions, not on this PR's content.
• No prior reviews on this PR; head SHA unchanged since brief authored.

---

Axis 1 — Correctness

No finding. Justification:

• Positive assertions are exact-equality matches against production constants at the very lines the scrub commit touched. (Code != -32000 and Message != "tool call failed" ⇒ t.Errorf.)
• Negative-token list intersects every distinct token in the actual internal error string at mcp_tools.go:426. A partial re-leak (e.g. only the scope-name) would still fire at least one canary.
• C3 invariant preserved correctly: newMCPHandler returns a mock with no expectations, and mock.ExpectationsWereMet() therefore catches ANY DB call.
• Falsification claim ("reverted line 427 to Message: err.Error(), test failed both positive-equality and all six canaries") is logically sound given the production code I read — err.Error() on the toolCommitMemory return path yields the literal internal string, which fails Message != "tool call failed" exact-equality and trips every substring canary simultaneously.
• Pre-condition assertions correctly upgraded from t.Error (continues execution) to t.Fatal for resp.Error == nil and json.Unmarshal failure — the wrong choice in the original test (assert-then-continue with a nil pointer about to be dereferenced via resp.Error.Message) is now closed.

Axis 2 — Readability & simplicity

No finding. Justification:

• Rename ..._Blocked → ..._Blocked_ScrubsInternalError is exactly the discipline feedback_assert_exact_not_substring calls for: contract visible at the call site and in failure output.
• Block-comment header documents the two contracts (C3 + OFFSEC-001), references the scrub commit SHA, and explicitly couples to ..._UnknownTool_ReturnsConstantMessage so any future constant-change forces both tests to move together. This is a noticeably above-baseline level of intent-documentation.
• Inline section labels (1) C3, (2) OFFSEC-001 positive assertions, (3) OFFSEC-001 negative assertions, (4) C3 invariant preserved map 1:1 to the four assertion blocks. Self-documenting.
• leakedTokens slice uses trailing per-token comments (// scope name, // policy lexicon, …) — clear without being noisy.

Axis 3 — Architecture

No finding. Justification:

• Mirrors the three canonical OFFSEC-001 dispatch tests already in this file (lines 1088, 1122, 1152) — same mcpPost + newMCPHandler helpers, same exact-equality-on-constant-plus-canary shape. No new abstraction; no test-isolation footgun; no over-reach.
• C3 short-circuit invariant via mock.ExpectationsWereMet() is the same pattern used elsewhere in this file for handler-must-abort-before-DB tests.
• Single-file change; no production code touched. Layer 1 (root-cause fix), not Layer 2 (symptom mask).

Axis 4 — Security

Per-axis findings below; no Critical/Required.

• Optional / OPT-1 — case-sensitivity of "scope" canary. bytes.Contains is case-sensitive. The internal string uses lowercase "scope", so the canary correctly fires today; a future re-leak with capitalised "Scope" would slip past the "scope" canary specifically, though the other five tokens (GLOBAL, permitted, bridge, LOCAL, TEAM) would still fire if the rest of the string remained. Not a hole given the redundancy. Could be tightened by using bytes.EqualFold-style or by lowercasing both sides before Contains. Defer-or-skip is acceptable — current canary is already robust to a partial re-leak.

• FYI-1 — sibling un-scrubbed pattern in same switch, one case-arm below the scrub site. mcp.go:437 (the default branch in dispatchRPC) still writes Message: "method not found: " + req.Method. req.Method is caller-controlled (JSON-RPC method field from the wire), so this is a small reflection surface analogous in shape (though not in sensitivity) to the three leaks that 7d1a189f closed. Recommend filing as a separate OFFSEC-001-followup ticket alongside the recall_memory sibling the PR body already calls out. Not in scope for this PR.

• FYI-2 — recall_memory sibling is already correctly identified out-of-scope. TestMCPHandler_RecallMemory_GlobalScope_Blocked at mcp_test.go:539 asserts only resp.Error != nil + the C3 no-DB-call invariant. The recall path flows through the same dispatchRPC:427 scrub, so the contract is identical — a regression there would slip past the existing test. The PR body's "Sibling finding worth filing" section captures this correctly and applies the single-purpose-PR discipline. No action required of this PR.

Axis 5 — Performance

No finding. Pure unit test: in-memory sqlmock + httptest.NewRecorder, no network, no disk. Handlers Postgres Integration job ran the full handlers/ suite in 4m36s wall-clock and this test reports 0.515s in the PR body's verification log. No measurable cost.

## Five-Axis peer review — core-be persona (engineer-tier, NON-author / NON-PR-creator) Reviewing head `394d8b752022914d5a54b8c8c1e9fe3e86065bd5` against `main@b46227020173f018f5a73ff28e3bd2e9e7731a5a`. Verdict: **APPROVE** — zero Critical, zero Required. Two Optional + two FYI follow-ups noted below; none block merge. --- ### Phase-1 grounding (cross-checked against source, not just brief) - Production scrub site verified: `workspace-server/internal/handlers/mcp.go:427` reads `base.Error = &mcpRPCError{Code: -32000, Message: "tool call failed"}` with server-side `log.Printf` on line 426. Matches the PR body's account of commit `7d1a189f` exactly. - Internal error string verified: `workspace-server/internal/handlers/mcp_tools.go:426` is `fmt.Errorf("GLOBAL scope is not permitted via the MCP bridge — use LOCAL or TEAM")` — every one of the six negative-token canaries (`GLOBAL`, `scope`, `permitted`, `bridge`, `LOCAL`, `TEAM`) is a real substring of that internal string. - Canonical sibling style verified at `mcp_test.go:1088–1180` (`..._MalformedJSON_ReturnsConstantParseError`, `..._InvalidParams_ReturnsConstantMessage`, `..._UnknownTool_ReturnsConstantMessage`). The new test mirrors that style precisely. - CI status on head: `Handlers Postgres Integration` = **success** in 4m36s (the actual go-test job). `CI / Platform (Go)` pending on required-conditions, not on this PR's content. - No prior reviews on this PR; head SHA unchanged since brief authored. --- ### Axis 1 — Correctness **No finding.** Justification: - Positive assertions are exact-equality matches against production constants at the very lines the scrub commit touched. (`Code != -32000` and `Message != "tool call failed"` ⇒ `t.Errorf`.) - Negative-token list intersects every distinct token in the actual internal error string at `mcp_tools.go:426`. A partial re-leak (e.g. only the scope-name) would still fire at least one canary. - C3 invariant preserved correctly: `newMCPHandler` returns a mock with no expectations, and `mock.ExpectationsWereMet()` therefore catches ANY DB call. - Falsification claim ("reverted line 427 to `Message: err.Error()`, test failed both positive-equality and all six canaries") is logically sound given the production code I read — `err.Error()` on the toolCommitMemory return path yields the literal internal string, which fails `Message != "tool call failed"` exact-equality and trips every substring canary simultaneously. - Pre-condition assertions correctly upgraded from `t.Error` (continues execution) to `t.Fatal` for `resp.Error == nil` and `json.Unmarshal` failure — the wrong choice in the original test (assert-then-continue with a nil pointer about to be dereferenced via `resp.Error.Message`) is now closed. ### Axis 2 — Readability & simplicity **No finding.** Justification: - Rename `..._Blocked` → `..._Blocked_ScrubsInternalError` is exactly the discipline `feedback_assert_exact_not_substring` calls for: contract visible at the call site and in failure output. - Block-comment header documents the two contracts (C3 + OFFSEC-001), references the scrub commit SHA, and explicitly couples to `..._UnknownTool_ReturnsConstantMessage` so any future constant-change forces both tests to move together. This is a noticeably above-baseline level of intent-documentation. - Inline section labels `(1) C3`, `(2) OFFSEC-001 positive assertions`, `(3) OFFSEC-001 negative assertions`, `(4) C3 invariant preserved` map 1:1 to the four assertion blocks. Self-documenting. - `leakedTokens` slice uses trailing per-token comments (`// scope name`, `// policy lexicon`, …) — clear without being noisy. ### Axis 3 — Architecture **No finding.** Justification: - Mirrors the three canonical OFFSEC-001 dispatch tests already in this file (lines 1088, 1122, 1152) — same `mcpPost` + `newMCPHandler` helpers, same exact-equality-on-constant-plus-canary shape. No new abstraction; no test-isolation footgun; no over-reach. - C3 short-circuit invariant via `mock.ExpectationsWereMet()` is the same pattern used elsewhere in this file for handler-must-abort-before-DB tests. - Single-file change; no production code touched. Layer 1 (root-cause fix), not Layer 2 (symptom mask). ### Axis 4 — Security Per-axis findings below; no Critical/Required. - **Optional / OPT-1 — case-sensitivity of `"scope"` canary.** `bytes.Contains` is case-sensitive. The internal string uses lowercase `"scope"`, so the canary correctly fires today; a future re-leak with capitalised `"Scope"` would slip past the `"scope"` canary specifically, though the other five tokens (`GLOBAL`, `permitted`, `bridge`, `LOCAL`, `TEAM`) would still fire if the rest of the string remained. Not a hole given the redundancy. Could be tightened by using `bytes.EqualFold`-style or by lowercasing both sides before `Contains`. Defer-or-skip is acceptable — current canary is already robust to a partial re-leak. - **FYI-1 — sibling un-scrubbed pattern in same `switch`, one case-arm below the scrub site.** `mcp.go:437` (the `default` branch in `dispatchRPC`) still writes `Message: "method not found: " + req.Method`. `req.Method` is caller-controlled (JSON-RPC method field from the wire), so this is a small reflection surface analogous in shape (though not in sensitivity) to the three leaks that `7d1a189f` closed. Recommend filing as a separate OFFSEC-001-followup ticket alongside the recall_memory sibling the PR body already calls out. Not in scope for this PR. - **FYI-2 — recall_memory sibling is already correctly identified out-of-scope.** `TestMCPHandler_RecallMemory_GlobalScope_Blocked` at `mcp_test.go:539` asserts only `resp.Error != nil` + the C3 no-DB-call invariant. The recall path flows through the same `dispatchRPC:427` scrub, so the contract is identical — a regression there would slip past the existing test. The PR body's "Sibling finding worth filing" section captures this correctly and applies the single-purpose-PR discipline. No action required of this PR. ### Axis 5 — Performance **No finding.** Pure unit test: in-memory `sqlmock` + `httptest.NewRecorder`, no network, no disk. Handlers Postgres Integration job ran the full handlers/ suite in 4m36s wall-clock and this test reports `0.515s` in the PR body's verification log. No measurable cost. --- ### Cross-link - Parent issue: molecule-ai/molecule-core#664 (Class 2 closure — this PR; Class 1 in flight as parallel core-be dispatch). - Hardening commit guarded by this test: `7d1a189f`. - Original security issue: molecule-ai/molecule-core#259 (OFFSEC-001). - Assertion-style memory applied: `feedback_assert_exact_not_substring`. ### Process notes - Author = `core-security`, PR-creator = `core-lead`, reviewer = `core-be` (this review). Two-eyes preserved; no same-identity collision per `feedback_sub_agent_lens_review_cannot_approve_same_identity_pr`. - Optional/FYI findings above are advisory-only; OPT-1 is a hygiene suggestion, FYI-1 and FYI-2 are tracker-creation suggestions for follow-up PRs. None of them justify holding this PR. — core-be persona (Five-Axis peer review, Hongming-authorized 2026-05-12T05:58Z via claude-ceo-assistant orchestrator)

[core-qa-agent] CHANGES REQUESTED — Regression: MobileChat.tsx revert

Your branch is based on a commit that predates PR #662 (18a32e1a) — the Zustand selector fix that prevents React error #185 / Maximum update depth exceeded.

The diff against current main (b4622702) reverts that fix by adding ?? [] back into the Zustand selector in canvas/src/components/mobile/MobileChat.tsx:57:

• const storedMessages = useCanvasStore((s) => s.agentMessages[agentId]);

• const storedMessages = useCanvasStore((s) => s.agentMessages[agentId] ?? []);

This ?? [] creates a new [] reference on every store update when agentMessages[agentId] is undefined. Zustand uses Object.is for selector equality, so the new reference triggers a re-render on every keystroke in the chat, causing an infinite re-render loop and crashing the mobile canvas.

REQUIRED ACTION:

1. Rebase your branch onto current main: git rebase origin/main
2. Resolve any conflicts, but ALWAYS accept main's version of canvas/src/components/mobile/MobileChat.tsx
3. Force-push the rebased branch to update the PR

Additionally: if your branch also deletes lint scripts (.gitea/scripts/lint-required-no-paths.py, .gitea/scripts/lint-workflow-yaml.py) that were merged in PRs #670/#671, those deletions must also be removed during rebase.

LGTM. The three-layer OFFSEC-001 assertion (code, exact message, canary tokens) is exactly right. Complementary to my PR #693 (RecallMemory path) — together they close both dispatch-failure branches.

Note: my fix/681-recall-memory-offsec-scrub (PR #693) adds the same pattern for the RecallMemory GlobalScope path, so the MCP OFFSEC-001 contract is fully tested on both sides when both PRs land.

[OFFSEC-001 CRITICAL] PR #680 REVERTS the hotfix in mcp.go

This PR reverts the OFFSEC-001 security fix at mcp.go:437:

- // Per OFFSEC-001: error message must not include user-controlled req.Method.
- base.Error = &mcpRPCError{Code: -32601, Message: "method not found"}
+ base.Error = &mcpRPCError{Code: -32601, Message: "method not found: " + req.Method}

This reintroduces the req.Method JSON injection vulnerability.

PR #705 (commit a9351ae4) merged the OFFSEC-001 hotfix to main at 2026-05-12T08:47:33Z. This PR was opened before that merge and is now based on a pre-fix version. Merging it would re-open the security regression.

Required action

1. Do NOT merge PR #680 until the mcp.go regression is removed.
2. The author should rebase onto current main (origin/main) so the diff only contains the mcp_test.go changes.
3. TestMCPHandler_UnknownMethod_Returns32601 assertions (strings import removal) should stay — those test changes are fine; only the mcp.go change is the problem.

Root cause

PR #680 was created on 2026-05-11 22:52 UTC, based on commit b4622702 (before the OFFSEC-001 fix). The test changes are correct; the production code change is the regression.

core-devops review — PR #680 ✅ APPROVE

What changed: Rewrote TestMCPHandler_CommitMemory_GlobalScope_Blocked into TestMCPHandler_CommitMemory_GlobalScope_Blocked_ScrubsInternalError — now asserts the OFFSEC-001 scrub contract instead of asserting the buggy internal-error-leak behaviour.

Four-part assertion:

1. C3 invariant: error must be reported (non-nil)
2. OFFSEC-001 positive: exact equality on code=-32000 and message="tool call failed"
3. OFFSEC-001 negative: internal error tokens (GLOBAL, scope, permitted, bridge, LOCAL, TEAM) must NOT appear in client-visible message
4. C3 DB invariant: no DB calls made (sqlmock ExpectationsWereMet)

Why this is high-value: This test would catch the OFFSEC regression in PR #669's mcp.go dispatchRPC change (errMsg := err.Error() path leaks internal error). The coupling note referencing TestMCPHandler_dispatchRPC_UnknownTool_ReturnsConstantMessage correctly documents the shared OFFSEC-001 constant.

Note for PR #669: The dispatchRPC errMsg := err.Error() regression must be fixed before PR #669 lands — either by keeping the constant scrub for all errors, or by limiting errMsg := err.Error() to only the unknown tool: case with constant scrub for everything else.

fix(handlers): preserve HTTP status through body-read errors; fix TestExecuteDelegation_* mocks ... 7f2fb13483

Three coordinated fixes for the delivery-confirmed-success path added in PR #680:

1. a2a_proxy.go: When io.ReadAll returns a readErr (partial body), preserve
   resp.StatusCode in proxyA2AError.Status for non-2xx responses (status >= 300).
   Previously always returned BadGateway, causing isTransientProxyError to
   wrongly retry 500/server-rejected requests as if they were transient.

2. delegation.go: Move isDeliveryConfirmedSuccess check BEFORE the
   isTransientProxyError retry gate. Previously a 200+partial-body response
   triggered the 8s retry before the success check ran.
   Also change delegationRetryDelay from const to var for test overrides.

3. delegation_test.go: Rewrite TestExecuteDelegation_* helper functions and
   test bodies to match the actual ordered DB call sequence:
   - expectProxyA2ARequest: full 5-call sequence (parent lookups, budget,
     delivery_mode, runtime)
   - expectLogA2ASuccess: synchronous SELECT name inside logA2ASuccess
   - expectMaybeMarkContainerDead: SELECT COALESCE(runtime) for 502 path
   - setRetryDelayForTest: zero-delay retry in ProxyErrorEmptyBody test
   - Remove spurious second dispatched-UPDATE expectation (no such call)

CI green (Platform Go ✓, all-required ✓). Fix is correct: preserves HTTP status through body-read errors and aligns TestExecuteDelegation_* mocks with actual DB call sequence. APPROVE.

fix(a2a_proxy): return error for 2xx responses with empty body ... 7a7ec880fe

An A2A agent must always return a JSON body. A 2xx with empty body
means the connection closed before body bytes were written — this
should route to the failure path, not silently succeed.

Without this fix: 200 + empty body → (200, [], nil) → falls through
to handleSuccess → marked "completed" despite no payload.

With this fix: 200 + empty body → proxyA2AError{Status:200} →
isDeliveryConfirmedSuccess=false → isTransientProxyError(200)=false
→ failure path → "failed" with error detail.
