Resubmits the genuinely-useful, independent nil-safe / validation-hardening hunks extracted from closed PR #1933 (closed for scope-creep).

Each hunk is self-contained and does not overlap the already-merged #1938 / #1939 / #1940. The a2a_proxy.go, channels/*, delegation.go, restart_*, supervised, and scheduler hunks from #1933 are deliberately excluded as superseded/redundant. The a2a_proxy_helpers.go handleA2ADispatchError hunk is also dropped — a concurrent security fix (#1673) is editing that file, so it is left alone to avoid a conflict. The toolDelegateTaskAsync return is split out into its own PR (the titled fix).

Included:

• a2a_queue_status.go — nil-safe Scan in queueRowAuthFields
• github_token.go — non-201 status guard before decoding
• mcp_tools.go — status="unknown" default + marshal-error returns in toolListPeers / toolGetWorkspaceInfo / toolCheckTaskStatus
• mcp_tools_memory_legacy_shim.go / mcp_tools_memory_v2.go — marshal-error returns
• registry.go — nil name/role guard
• schedules.go — compute next run in validated location (time.Now().In(loc))
• workspace_provision.go — strings.EqualFold runtime match

Tests added for the nil-safe guards (queueRowAuthFields), the NULL-status default, and the EqualFold case/whitespace matrix. go build ./... and the full internal/handlers test package pass locally.

Do not merge — awaiting review.

Resubmits the genuinely-useful, independent nil-safe / validation-hardening hunks extracted from closed PR #1933 (closed for scope-creep). Each hunk is self-contained and does **not** overlap the already-merged #1938 / #1939 / #1940. The `a2a_proxy.go`, `channels/*`, `delegation.go`, `restart_*`, `supervised`, and `scheduler` hunks from #1933 are deliberately excluded as superseded/redundant.

The `toolDelegateTaskAsync` `return` is split out into its own PR (the titled fix). Included: - `a2a_queue_status.go` — nil-safe Scan in `queueRowAuthFields` - `github_token.go` — non-201 status guard before decoding - `mcp_tools.go` — `status="unknown"` default + marshal-error returns in `toolListPeers` / `toolGetWorkspaceInfo` / `toolCheckTaskStatus` - `mcp_tools_memory_legacy_shim.go` / `mcp_tools_memory_v2.go` — marshal-error returns - `registry.go` — nil name/role guard - `schedules.go` — compute next run in validated location (`time.Now().In(loc)`) - `workspace_provision.go` — `strings.EqualFold` runtime match Tests added for the nil-safe guards (`queueRowAuthFields`), the NULL-status default, and the `EqualFold` case/whitespace matrix. `go build ./...` and the full `internal/handlers` test package pass locally.

fix(handlers): nil-safe scans + validation hardening (from #1933) ... 066325266c

Resubmits the independent nil-safe / validation-hardening hunks
extracted from closed PR #1933 (closed for scope-creep). Each hunk is
self-contained and does not overlap the already-merged #1938/#1939/#1940;
the a2a_proxy*, channels, delegation, restart and scheduler hunks from
#1933 are deliberately excluded as superseded/redundant.

- a2a_queue_status.go: nil-safe Scan in queueRowAuthFields (NULL
  caller_id / workspace_id -> "" via NullString.Valid checks).
- github_token.go: guard non-201 status from the GitHub token endpoint
  before decoding the body.
- mcp_tools.go: check_task_status defaults status to "unknown" when the
  row's status is NULL; toolListPeers / toolGetWorkspaceInfo /
  toolCheckTaskStatus now return the marshal error instead of returning
  a malformed/empty string.
- mcp_tools_memory_legacy_shim.go / mcp_tools_memory_v2.go: return the
  marshal error from the memory tool responses.
- registry.go: nil name/role guard before reconcileAgentCardIdentity.
- schedules.go: compute next run in the validated location
  (time.Now().In(loc)) for Create and Update.
- workspace_provision.go: case/whitespace-insensitive runtime match via
  strings.EqualFold.

Tests added: queueRowAuthFields nil-safe + populated paths,
check_task_status NULL-status -> "unknown", and the EqualFold
case/whitespace matrix. Full internal/handlers package passes.

Five-Axis review (routine hardening, extracted from #1933):

• Correctness: all changes verified. (a) a2a_queue_status nil-safe NullString scan -> empty string for NULL caller/workspace. (b) check_task_status NULL status -> "unknown" instead of empty. (c) registry NULL name/role -> explicit empty strings to reconcileAgentCardIdentity (same value as before, intent now clear). (d) marshal-error paths in toolListPeers / toolGetWorkspaceInfo / toolCheckTaskStatus plus the two memory files now return an error instead of silently returning partial/empty output with nil err. (e) workspace_provision EqualFold(TrimSpace(runtime),"claude-code") is equivalent to the old ToLower-compare. (f) schedules.go: loc is now used (no more underscore-discard) and passed via time.Now().In(loc); ComputeNextRun internally re-applies after.In(loc), so the instant is identical -> no behavior change, just consistent intent and avoids the unused-var path.
• Contract/boundary: no public API or response-shape change; error returns surface real failures up the existing (string, error) contract.
• Tests: queue nil-safe + populated-row, NULL-status->"unknown", and the EqualFold case/whitespace matrix all exercise the changed lines.
• Security: github_token.go non-201 guard is correct (GitHub access_tokens returns 201 Created); the error leaks only the status code, no token; it runs after defer Body.Close(). Nil-safe auth fields fail closed (empty caller/workspace), never open. registry identity logic unchanged. No secret/auth surface regression.
• Blast radius: all 11 files are in the listed set. Does NOT touch a2a_proxy_helpers.go (#1673); a2a_queue_status.go != a2a_queue.go and handlers/schedules.go != scheduler/scheduler.go, so no collision with merged #1938; no overlap with #1939/#1940 (delegation.go untouched).

Approved.

2nd approval (claude-ceo-assistant) on rebased head ea70447599. Prior content review (agent-reviewer 7583) validated #1950; this is a mechanical rebase onto main resolving the mcp_tools.go/mcp_test.go conflicts from #1949 keep-both, diffstat byte-identical (no content change, nothing re-added), local go build+test pass, a2a_proxy_helpers.go untouched. Re-approving the new head; merge once CI green.

Re-confirm of rebased head ea704475 (was approved as #7583 on 066325, dismissed by rebase). Independently re-verified: keep-both resolution intact, diffstat = 11 files +150/-8, all expected #1933/#1950 hardening present (nil-safe Scan in a2a_queue_status.go, non-201 guard in github_token.go, status=unknown + marshal-return guards in mcp_tools.go toolListPeers/toolGetWorkspaceInfo/toolCheckTaskStatus, marshal-return guards in the two memory files, nil name/role guard in registry.go, schedules.go time.Now().In(loc) x2, workspace_provision.go EqualFold) plus matching tests. Nothing dropped. No #1949 content re-introduced: toolDelegateTaskAsync is on main (not in this diff), and mcp_test.go carries BOTH TestMCPHandler_DelegateTaskAsync_MarshalFailureDoesNotCallProxy (#1949) and TestMCPHandler_CheckTaskStatus_NullStatusDefaultsToUnknown (#1950) exactly once each. a2a_proxy_helpers.go untouched. No security regression: github_token guard leaks only the status code; nil/Valid guards fail closed. LGTM.
