Root cause of "no voiceover": in audioMixCommand the [voice] label was used both
as the sidechaincompress key AND as an amix input. FFmpeg does NOT auto-split a
reused label, so the ducking sidechain consumed the voice entirely and the amix
reference got no audio -- the narration never made it into any final mix (every
render played ducked music with a silent hole where the voice should be).
Fix: explicitly `asplit=2[voice_key][voice_mix]` so one copy keys the duck and one
copy stays in the mix. Measured: voice window went from ~-30..-53 dB (silent) to
~-16 dB (present, leading the bed). Revert the compensating +8 dB over-boost back
to unity; music bed lowered to -14 dB so narration leads cleanly.
Also make SFX direction OPTIONAL in the validator (matching the earlier
voiceover-optional change) so a clean music+narration edit with no sound effects
validates. Regression test added for the asplit. mvn -o verify green (248 tests).

Push the highlight output toward a genuinely cinematic look after a human review
found it functional-but-not-cinematic:
- HighlightFfmpegRenderer: add a 2.39:1 letterbox and subtle film grain to each
graded segment; raise overlay placement above the letterbox bar. (A time-based
crop-zoom push-in was prototyped and removed: FFmpeg crop cannot use the `t`
variable for width/height; a zoompan push-in is a possible follow-up.)
- HighlightDirectorPlanValidator: make voiceover OPTIONAL so a music-driven edit
can carry no narration (lines still validated when present).
Combined with a no-voiceover, driving-orchestral, slow-motion-hero director plan,
this yields a letterboxed, richly graded, music-led cinematic cut. mvn -o verify
green (247 tests, 0 failures).

The local-cv provider was never exercised end to end (its bootstrap was
prohibited), and hid a latent bug: the JDK HttpClient defaulted to HTTP/2 and
negotiated an h2c cleartext upgrade that the HTTP/1.1-only worker (uvicorn/h11)
mishandled by dropping the request body, so every call returned HTTP 422. Pin the
client to HTTP/1.1.
With this fix the resident YOLOv8 worker (run offline against the existing
yolov8n.pt, no bootstrap script) classifies the sample source as CAR_VLOG at 0.95
with measured OpenCV blur/exposure and a real car label, replacing the previous
filename-keyword GENERIC_VLOG fallback. Provider remains opt-in via runtime
override; the committed localpoc profile keeps the heuristic default.
Also ignore yolov*.pt.license.txt (provenance for the git-ignored weights).
mvn -o verify green (247 tests, 0 failures).

The highlight renderer now selects a filmic grade per story beat, read from the
EditPlan style key (safeKey: style_<category>_<storyPurpose>), so no change to the
shared EditDecision or its serialization is needed:
- opening_hook: calmer, cooler, softer contrast (linear_contrast, gentle vignette)
- rising_energy / default: balanced base grade (medium_contrast)
- hero_payoff: richest, warmer, stronger S-curve and deeper vignette (strong_contrast)
Threads plan.style() into segmentCommand -> cinematicVisualFilter. Multi-clip
FfmpegEditRenderer untouched. Test added; mvn -o verify green (247 tests, 0 failures).

Replace the plain hard-cut white caption with a refined 48px caption, a soft drop
shadow, a thin subtle border, and a smooth alpha fade in and out (0.4s ramps)
within each overlay timeline window. Highlight renderer only; the multi-clip
renderer and overlay placement/safe-area logic are unchanged. Test added;
mvn -o verify green (246 tests, 0 failures).

Phase 3 quality fixes for the highlight renderer (multi-clip FfmpegEditRenderer
left untouched):
- cinematicVisualFilter: replace the weak fixed eq with a deliberate filmic grade
(curves medium_contrast S-curve + teal-orange colorbalance + eq + unsharp +
vignette). Richer blue, warm highlights, tonal contrast. Still one uniform look;
beat/category-specific grading is future work (needs a validated grade enum).
- audio mix: add a brickwall limiter (alimiter limit=0.72) after loudnorm. The
first render clipped at 0.0 dBFS true peak; measured re-render now lands
-1.7/-2.7/-2.8 dBFS per highlight (all within the -1.5 dBTP gate), integrated
loudness -16.3 LUFS.
Test updated; mvn -o verify green (245 tests, 0 failures).

Activated with --spring.profiles.active=localpoc. Points only at pre-provisioned
local model paths (Piper voice, MusicGen, AudioLDM2), disables bootstrap
auto-start, uses heuristic visual analysis, isolates PoC input/output dirs, and
keeps render disabled + director approval required. Base/production defaults are
untouched.
