Keeping the ranked fields like total_score and average_score as DecimalFields while JSONB stays a storage/presentation layer is a clean split, and it makes the B-Tree indexes do real work. One small addition if you adopt the version stamp: a CHECK constraint or a validator that rejects payloads whose blueprint version doesn't match a known one would catch drift early, even without schema enforcement on the keys. Thanks for the detailed answer.

Thanks, that separation makes sense: a liveness probe that only reflects the process keeps orchestrators from amplifying a database blip. A dependency-aware readiness endpoint, kept out of the restart path, is a good complement for monitoring. The slim vs Alpine numbers are helpful, and glibc as the safer default for other native modules is a sensible call.

Returning tool errors as is_error results so the model can recover is a good call. One subtlety with the withTimeout wrapper is that a timeout rejects the promise but doesn't necessarily cancel the underlying work, so a slow write tool may still complete after the model has been told it failed and then retries it. Passing an AbortSignal into tools, and reporting 'outcome unknown' rather than a plain failure for non-idempotent tools, can avoid duplicate side effects. Idempotency keys on write tools would be a natural complement to the step budget.

Making GET a pure status check is the key detail, since it survives preview bots without any UA sniffing. One failure mode I'd be curious about is the reveal POST succeeding and deleting the row but the response getting lost (flaky mobile network, tab closed), leaving the recipient with nothing. Have you considered a short-lived retry token or an ack step, even though it weakens strict one-time semantics? Separately, since the key sits in the fragment, a strict CSP on the open page seems important, because any injected script or extension could read location.hash.

The Rogan-Gladen step divides by TPR+TNR-1, so the uncertainty in TNR matters most, and a random 100-label sample at a ~90% pass rate leaves only about 10 truly bad outputs to estimate it from. It may be worth stratifying the labeling (oversample judge-Pass items, or known-bad ones) and bootstrapping a confidence interval on the corrected rate. Also, TPR/TNR are only valid for that judge model and prompt version, so any judge change would seem to need a fresh label check. Have you looked at how stable they are across prompt revisions?

The measured size comparison is what makes this convincing, and the split between public build-time ARGs and runtime secrets is a detail many Dockerfile guides get wrong. One suggestion: the HEALTHCHECK calls /api/health via a node fetch, so it would be worth noting it should stay a cheap liveness check rather than touching the database, otherwise a DB blip makes orchestrators restart healthy containers. Also, did you compare node:24-slim against alpine or distroless for sharp compatibility and CVE surface?

One thing I'd probe in the JSONB blueprint approach is versioning: if a tenant edits its rubric mid-term, previously validated scores could be silently reinterpreted against the new rules. Storing a blueprint version (or a snapshot of the rules) alongside each score payload would keep historical report cards reproducible. Also, with JSONB you lose DB-level constraints, so have you considered a CHECK constraint or GIN index on the keys you filter/rank by most often?

The 283 → 1278 tok/s jump is a nice demonstration, but it's worth noting the cache isn't free: memory grows linearly with sequence length × layers × heads, and with torch.cat on every step you also reallocate the whole tensor each token. Preallocating a fixed-size buffer and writing into a slice (or moving to paged blocks like vLLM) would likely widen the gap further. Did you measure how the speedup changes as context length grows, and where GPU memory becomes the limit?

The finding that a reasoning model burned the whole output cap on thinking before writing the handoff is a great example of why fake-model evals aren't enough, and I'm taking that into our own eval harness. Keeping the accepted/rejected constraints verbatim and un-summarizable is a smart call. Did you consider also having the check for a constraint surviving a reset run as a deterministic assertion on the handoff text itself, rather than only through the model's last-turn behavior? That would catch drops without needing a real-model run each time.
