Fixes molecule-core#1117.

Problem

Platform(Go) -race failed on TestProxyA2A_Upstream502_TriggersContainerDeadCheck and TestProxyA2A_Upstream502_AliveAgent_PropagatesAsIs because the fakeCPProv test double mutated shared state (calls, stopCalls, startCalls, running) without synchronization. IsRunning / Stop / Start can run on detached restart goroutines while the test goroutine reads the counters.

Fix

• Add sync.Mutex to fakeCPProv.
• Guard all field mutations/reads inside methods.
• Expose thread-safe getters Calls(), StopCalls(), StartCalls() and setter setRunning().
• Update all test assertions to use the getters/setter.

Verification

• go test ./internal/handlers/ -count=1 passes
• golangci-lint run ./internal/handlers/ clean

Fixes molecule-core#1117. ## Problem `Platform(Go) -race` failed on `TestProxyA2A_Upstream502_TriggersContainerDeadCheck` and `TestProxyA2A_Upstream502_AliveAgent_PropagatesAsIs` because the `fakeCPProv` test double mutated shared state (`calls`, `stopCalls`, `startCalls`, `running`) without synchronization. `IsRunning` / `Stop` / `Start` can run on detached restart goroutines while the test goroutine reads the counters. ## Fix - Add `sync.Mutex` to `fakeCPProv`. - Guard all field mutations/reads inside methods. - Expose thread-safe getters `Calls()`, `StopCalls()`, `StartCalls()` and setter `setRunning()`. - Update all test assertions to use the getters/setter. ## Verification - `go test ./internal/handlers/ -count=1` passes - `golangci-lint run ./internal/handlers/` clean Co-Authored-By: Claude <noreply@anthropic.com> 🤖 Generated with [Claude Code](https://claude.com/claude-code)

fix(handlers): synchronize fakeCPProv to eliminate TestProxyA2A data races (#1117) ... f0f104ab78

Platform(Go) -race was failing on TestProxyA2A_Upstream502_* because the
fakeCPProv test double mutated shared state (calls, stopCalls, startCalls,
running) without synchronization. IsRunning/Stop/Start could run on detached
restart goroutines while the test goroutine read the counters.

Changes:
- Add sync.Mutex to fakeCPProv.
- Guard all field mutations/reads inside methods.
- Expose thread-safe getters Calls(), StopCalls(), StartCalls() and setter
  setRunning().
- Update all test assertions to use the getters/setter.

Tests:
- go test ./internal/handlers/ -count=1 passes.
- golangci-lint run ./internal/handlers/ clean.

Fixes molecule-core#1117.

Independent 2nd-genuine review for molecule-core#3163 @ f0f104ab78.

REQUEST_CHANGES pending required verification. Code review of workspace-server/internal/handlers/a2a_proxy_test.go is clean: fakeCPProv now guards calls/stopCalls/startCalls/running with a mutex, all post-construction reads use Calls()/StopCalls()/StartCalls(), the only runtime write uses setRunning(), and remaining struct-literal initializations happen before concurrent use. The accessor refactor preserves the dead-check and access-check assertions that exposed the original TestProxyA2A races.

Blocker: I cannot confirm the requested Platform(Go) -race proof on this head. The current-head status set does not include a CI / Platform (Go) context; observed red contexts are qa-review/security-review approval gates and sop-checklist, with E2E API still pending. I also attempted a local focused go test -race -count=50 ./internal/handlers -run TestProxyA2A_... on f0f104a, but this container has no go binary, so I cannot supply the local fallback proof.

Approve path: get CI / Platform (Go) on f0f104a green, or provide an equivalent same-head race run artifact. No code-level blocker found.

5-axis review complete on head f0f104ab78.

Correctness: the fakeCPProv synchronization directly addresses the TestProxyA2A race: calls, stopCalls, startCalls, and running are now accessed through a mutex-backed API, with test assertions moved to the getters and the runtime mutation moved to setRunning.
Robustness: the existing async restart goroutine can now race safely with assertions; the struct literals only seed initial state before concurrent use.
Security/performance: test-only change; no production behavior, token handling, or runtime path changes. Mutex cost is irrelevant in tests.
Readability: the helper API makes the concurrency contract explicit without broadening the fixture scope.

CI discipline: own-head CI / Platform (Go) is success on f0f104ab78.

Independent re-review for molecule-core#3163 @ f0f104ab78.

APPROVE. The prior verification-only RC is resolved: CI / Platform (Go) is success on this exact head (run 394068, job 546752).

Code review remains clean. fakeCPProv guards the shared calls, stopCalls, startCalls, and running fields with a mutex; test assertions use Calls()/StopCalls()/StartCalls(); the only runtime mutation uses setRunning(); remaining struct literal writes are pre-concurrency setup. The accessor refactor preserves the original dead-check and access-check assertions while removing the restart-goroutine/test-goroutine race. Test-only change; no production behavior or security surface change.
