Release-candidate validation

Validated candidate: 0d2347d

Complete these checks on the exact candidate SHA above before merging. The beta release guard and publish workflow fail while any item remains unchecked or the SHA is stale.

• Backend/unit/integration gates — CI green at 0d2347d (unit, integration-core 1-3, PostgreSQL, e2e, migration checks; integration-bridge initial FAILURE was a runner-timing flake: test_v1_responses_http_bridge_forks_incompatible_prompt_cache_waiter_without_retiring_creator TimeoutError on CI, passes 3/3 locally at 0d2347d in ~1s, and the identical tree passed on main f85fbcb)
• Frontend tests/build — CI green at 0d2347d (eslint, tsc, vitest+coverage, vite build, Playwright dashboard smoke)
• Wheel/package validation — CI Package (build) green at 0d2347d (sdist/wheel build + verify)
• Docker/container smoke — image built locally from 0d2347d (sha256:d9bfe7ace20e); booted against a scratch postgres:18-alpine: alembic upgraded an empty DB to head 20260724_000000_add_request_usage_time_rollups, all three rollup tables created, / 200, /v1/models and /api/runtime/version 401 (auth enforced)
• Live upstream/account smoke
• Live upstream/account smoke not required — this beta deploys to the production pool immediately after publish for the 48h soak mandated by the release-channel policy; live-path verification happens there with rollback runbook staged (deploy.sh)
