Bug: After an authenticated non-200 /registry/register stamps last_register_failure_at, a later healthy heartbeat that backfills agent_card did not clear that marker. evaluateStatus therefore kept the workspace stuck in degraded forever.

Fix: In the heartbeat backfill path, clear last_register_failure_at in the same UPDATE that writes the agent_card.

Verification: Added TestHeartbeatHandler_BackfillAgentCard_ClearsRegisterFailure covering the degraded→online recovery path.

SOP checklist

• Comprehensive testing performed — unit test covers the degraded→online recovery path
• Local-postgres E2E run — N/A (registry handler unit test; no DB schema change)
• Staging-smoke verified or pending — N/A (registry status evaluation, not provisioning)
• Root-cause not symptom — root cause is the missing last_register_failure_at reset on healthy heartbeat backfill
• Five-Axis review walked — correctness (single-column reset), readability (commented), architecture (reuse existing backfill path), security (no new auth path), performance (single UPDATE)
• No backwards-compat shim / dead code added — no shim; behavior change is the fix
• Memory consulted — #2659/#2665 registry-degraded context

fix(registry): clear last_register_failure_at on healthy heartbeat agent_card backfill ... dd3dad7952

A transient /registry/register failure stamps last_register_failure_at and
forces the workspace to degraded. When a subsequent heartbeat carries a
valid agent_card and backfills the missing card, it is now a healthy recovery
path, so clear last_register_failure_at in the same UPDATE. Without this,
evaluateStatus keeps the workspace stuck degraded forever.

APPROVED: reviewed head dd3dad7952 with the 5-axis lens. CI / all-required is green; the red staging/SOP contexts are outside this required-code path. The change is scoped to the heartbeat agent_card backfill recovery: when a healthy heartbeat writes a missing agent_card, it also clears last_register_failure_at before evaluateStatus reads it, allowing degraded->online recovery once error_rate/runtime_state are healthy. It preserves the agent_card IS NULL guard, does not broaden auth or registration behavior, and the new sqlmock test covers the degraded recovery path and status transition. No blockers found.
