The warmup scheduler's circuit-breaker keys were written to Redis without `REDIS_KEY_PREFIX`, so they escaped OmniRoute's namespace and could collide with another app sharing the instance — the one Redis surface the prefix wasn't reaching. Probe: 2/2 pass in `tests/unit/lib/warmupScheduler/redisCircuitBreakerStorePrefix.test.ts`, covering both the prefixed case and the unset/blank case where keys must stay unchanged.
**Batch validation** — boarded with the other 10 PRs of your batch into one worktree cut from `release/v3.8.51`; every PR verified as an ancestor of the combined HEAD before validating.
- Focused tests across all 11 PRs: **104/104 pass** on the combined tree.
- Gates on the combined tree: `check-changelog-integrity` PASS, `check-complexity` PASS, `check-cognitive-complexity` PASS, `typecheck:core` PASS, `check:open-sse-typecheck` PASS.
- `check-file-size` is red, but reproduces with byte-identical line counts on the pure `release/v3.8.51` tip (`open-sse/handlers/imageGeneration.ts` 3304, `open-sse/services/combo/roundRobinCombo.ts` 1221, `open-sse/utils/stream.ts` 3115). Inherited base-red, nothing added by this batch — it is also why this PR's "Fast Quality Gates" check was red.
**Reconciled** — this PR was `CONFLICTING`. The conflict was in `docs/reference/ENVIRONMENT.md` and purely additive: the release tip had inserted `APP_BIND_HOST` / `QDRANT_BIND_HOST` / `BIFROST_BIND_HOST` rows directly above the `REDIS_KEY_PREFIX` row you edited. Kept both sides — the tip's three new rows and your updated description naming the warmup circuit breaker — then merged the current release branch in (120a92f6) and re-ran your focused test on the reconciled tree: 2/2 pass. No line of your diff was dropped.
Thanks, @datrixlab — you also updated `.env.example`, `docs/ops/REDIS_PRODUCTION_CONFIG.md` and `ENVIRONMENT.md` alongside the code, which is why the only thing left to do here was a mechanical conflict resolution.
Validated on the combined board over tip 80d931ae: quota-redis-store (incl. the KEY_PREFIX derivation test), local-redis-status and rate-limiter-redis-optional green, typecheck:core clean. One pre-merge fix pushed to the branch: docs/reference/ENVIRONMENT.md gained the REDIS_KEY_PREFIX row (env-doc-sync gate requires every .env.example var documented). Board note: the redis tests leave an ioredis retry handle open and hang the runner exit locally — assertions all pass; pre-existing pattern, not from this PR. Thank you @MeRezaRezaei!
