Re-implementation of #2045 against main (original was mistakenly based on staging).

Changes:

• Replace http.DefaultClient with 10s timeout client in cp_config.go.
• Add panic recovery in goroutines: bundle provision, SSE idle watcher, terminal stdout/PTY/stdin bridges.
• Pass context.Context to queryPeerMaps and use QueryContext.
• Add deferred tx.Rollback() in workspace Create handler.
• Add panic recovery in background cleanup goroutines: MCP rate limiter, general rate limiter, secrets rotation.
• Check error returns on broadcaster.RecordAndBroadcast, db.ExecContext, tx.Exec, and rows.Err() in 12 files.

Comprehensive testing performed

• go test ./... passes on workspace-server after changes
• go vet ./... clean
• golangci-lint passes

Local-postgres E2E run

• Handlers Postgres Integration job passes (real Postgres via testcontainers)

Staging-smoke verified or pending

• Pending post-merge — these are defensive code changes (error checks + panic recovery) with no new external behavior to smoke-test.

Root-cause not symptom

Root cause: unchecked errors and missing panic recovery in goroutines led to silent failures and potential crashes. Symptom: flaky tests, missing error logs, goroutine panics taking down handlers.

Five-Axis review walked

• Correctness: All error returns are now checked; panic recovery prevents goroutine crashes.
• Readability: Changes are mechanical (add if err != nil { log.Printf(...) } or defer recover()).
• Architecture: Follows existing patterns in the codebase (log.Printf for non-fatal errors, gin.Recovery() for HTTP handlers).
• Security: No new input surface; purely defensive.
• Performance: Negligible — one deferred recover per goroutine, one error check per call.

No backwards-compat shim / dead code added

Yes — no shim. Pure additions of error checks and panic recovery; no deprecated code introduced.

Memory/saved-feedback consulted

• Issue #2045 (original staging-based PR) requested these exact changes.
• Prior session fixed similar unchecked-error patterns in bundle/importer.go and channels/manager.go.

Re-implementation of #2045 against main (original was mistakenly based on staging). Changes: - Replace `http.DefaultClient` with 10s timeout client in `cp_config.go`. - Add panic recovery in goroutines: bundle provision, SSE idle watcher, terminal stdout/PTY/stdin bridges. - Pass `context.Context` to `queryPeerMaps` and use `QueryContext`. - Add deferred `tx.Rollback()` in workspace Create handler. - Add panic recovery in background cleanup goroutines: MCP rate limiter, general rate limiter, secrets rotation. - Check error returns on `broadcaster.RecordAndBroadcast`, `db.ExecContext`, `tx.Exec`, and `rows.Err()` in 12 files. ## Comprehensive testing performed - [x] `go test ./...` passes on workspace-server after changes - [x] `go vet ./...` clean - [x] golangci-lint passes ## Local-postgres E2E run - [x] Handlers Postgres Integration job passes (real Postgres via testcontainers) ## Staging-smoke verified or pending - [ ] Pending post-merge — these are defensive code changes (error checks + panic recovery) with no new external behavior to smoke-test. ## Root-cause not symptom Root cause: unchecked errors and missing panic recovery in goroutines led to silent failures and potential crashes.

APPROVED on current head 7c9d895b0b. 5-axis review: adds bounded HTTP timeout, panic recovery around background goroutines, context-aware DB peer queries, and an idempotent tx rollback cleanup. Changes improve robustness/fail-closed behavior without exposing secrets, weakening auth/gates/merge-control, or adding blocking hot-path work. Imports and call-site updates are consistent; BP-required contexts are present+green.

APPROVE: verified current head. Operational hardening only: CP config HTTP timeout, context-aware peer queries, rollback cleanup, and panic containment/logging in async bridges/sweepers. BP-required contexts present+green and mergeable=true. No gate/auth/merge-control weakening or regression found. Note: post-#2407 qa/security governance contexts are not green, so the uniform gate would still block until satisfied.
