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).

Record the operator-approved first render and the verified grade + true-peak
limiter results (TP -1.7/-2.7/-2.8 dBFS, I -16.3 LUFS) with commit references.

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.

Replace the unusable audiocraft path (requires xformers, which has no Intel-Mac
build) with runtimes proven to work offline on this machine:
- music: transformers MusicGen (facebook/musicgen-small)
- sfx: diffusers AudioLDM2 (cvssp/audioldm2), resampled 16k -> 48k
- voiceover: Piper (unchanged), normalized to 48 kHz mono
The worker CLI contract and exit codes are preserved, so the Java
LocalAssetSynthesizer license gate and fail-closed behavior are unchanged.
Add tools/provision_local_models.py to materialize models into models/ from the
local HF cache with no network. Models and their license sidecars live under the
git-ignored models/ dir; both audio models are non-commercial (CC-BY-NC-4.0 /
CC-BY-NC-SA-4.0), recorded for later production review.
Add docs/cinematic-highlight-poc-plan.md tracking the PoC plan and milestones.
mvn -o verify: 245 tests, 0 failures/errors/skips (unchanged).
