VOICE_V5 word-attack smoothing acceptance

Status: Accepted for VOICE_V5.

VOICE_V5 keeps the VOICE_V4 repeated-subword smoothing and changes word-boundary connected starts so they bloom into the syllable body instead of jumping out of the quiet bridge.

Scope

• dootdoot --version reports dootdoot VOICE_V5.
• The embedded semantic mapping remains the locked token-to-axis table in assets/dootdoot_asset_v1.doot.
• Subword and word-boundary connections are distinct renderer states.
• Word-boundary starts ramp from a low bridge-matched floor instead of reusing the high subword connection floor.
• Word-boundary vowels begin from a rounded oo-leaning pre-shape and open into the semantic vowel target.
• Upper-mid sparkle and archetype texture are damped during the word-opening bloom.
• The committed golden WAV hashes were regenerated under VOICE_V5.

Directional Check

Fixture phrase: I am so excited I am so excited I am so excited I am so excited.

The check measures median word-start energy and derivative roughness in the first 18 ms after each bridged word boundary relative to the following 45-85 ms body window. Lower values mean the word start swells into the body instead of spiking over it.

set	median word-start/body level ratio	median word-start/body roughness ratio
VOICE_V4 dootdoot	2.714	2.376
VOICE_V5 dootdoot	0.375	0.361

This is a directional listening aid. The sample-level contract remains the golden WAV hash fixture.
