memory: Lobe TTS fixed by aliasing stock OpenAI model names at the gateway

Lobe's TTS had never worked. It sends model:"tts-1" and LiteLLM resolves the
model name before routing, so it 403'd against the scoped key's allow-list and
never reached :8198 -- our belief that an unknown model routes to the gateway
default was true of the gateway and false of the LiteLLM path, which is what
hid it.

Fixed at the gateway rather than the client: tts-1, tts-1-hd and gpt-4o-mini-tts
aliased to the same upstream as ext-tts, and added to the lobe-chat-esh
allow-list. Verified with Lobe's exact payload on Lobe's own key. The obsolete
'one-time human UI pass' follow-up is dropped.

Banks two durable facts: those aliases are independent DB rows that must move if
ext-tts repoints, and the infra-ops key has admin rights for /model/new and
/key/update so this class of work does not need sk-corvid.

LiteLLM `char-rp-reasoning` + `char-rp-fable` both route to it (deliberate repoint, documented in `stacks/litellm/conf/config.yaml`). `darkscarlett-charrp-reasoning` is `compose down`, weights intact at `/tank/aimodels/darkscarlett-nvfp4-work/`. **⏳ STILL AWAITING operator's hands-on read of FF prose** (refusal question settled: FF 15.8% vs DS 92.5% cold-framing; DS v1.0 never abliterated). ⚠ FF reasons 2.1–4.6k chars → use `max_tokens` ≥3072. `ReadyArt/Dark-Scarlett-27B-v2.0` (Qwen3.8) is GATED (`403 awaiting review`) — operator ruled not-interesting, do NOT re-propose. **DS regeneration for brokkr RETIRED 2026-08-17 — unqueued, do NOT run** (`9c1405b`): brokkr withdrew on the operator's call because (a) our `ictrl-pair-unwrapped`/`-wrapped` control isolates the classifier over-fire cleanly where DS's cross-class delta only bounded it, and (b) **DS v2 releases soon**, so a k=5 v1 baseline baselines a superseded version. Spec at `services/refusal-probe/darkscarlett-regen-spec.md` stays banked as the record of the run that will not happen (axes + per-class grading asymmetry still correct, checklist struck through). No GPU1 window was ever spent. A DS-**v2** characterization would be a fresh purpose-scoped ask.

Verified with Lobe's exact payload on Lobe's own key: 200, 69,740 B, MPEG. ⚠ **These three are DB rows, not references — if `ext-tts` repoints, they must move with it.** Done with the **infra-ops admin key**, not `sk-corvid`: it has `/model/new` + `/key/update` rights, so this class of ask never needs the master key. Also live: **tts-gateway v4 defaults `response_format` to mp3** (tts-dev shipped it; 122,924 B wav → 27,692 B mp3 same utterance; every in-house consumer already pins the field, blast radius checked pre-ship).
