The first real boot gave the chance to measure what warming actually buys, and
the trial's numbers were wrong:
- Empty registry, register only, then time: the FIRST synthesis of a freshly
registered voice cost 1 883 ms; the next two 1 283 and 1 226 ms. A ~110-word
request cost 9.4 s and then 9.8 s.
- So the published 6.2–8.0 s cold / first-audio-byte 5 530 ms / later-requests
0.5 ms ladder does not reproduce, and request time tracks the audio generated
rather than snapshot state. The 0.5 ms figure is an internal state-restore
cost, never an end-to-end request time.
- Warming still earns its place for a different reason than the page claimed:
the registry is memory-only and re-registering does not warm, so a boot without
the hook leaves the façade answering 400 for every name. The saving is ~0.6 s.
Law 1 of [[Frank TTS Engine]] is re-titled the registry law and carries the
measured numbers; its example journal line is a real one from today; the
troubleshooting row for "first request of the day is slow" — the retired law's
symptom — is replaced by the argument-cap fault that actually happened. The same
ladder in the research brief is annotated rather than erased, and [[Voice Packs]]
step 6 stops claiming the hook registers only packs it has not seen (the engine
replaces a name it already holds).
