When ?backend=<url> pointed at a server that wasn't running (e.g. user
forgot to start ruview-pointcloud serve before clicking Connect ESP32),
the viewer was retrying 10 Hz forever — flooding the console with
ERR_CONNECTION_REFUSED and offering no guidance about what was wrong.
Two fixes:
1. Replace setInterval(fetchCloud, 100) with self-rescheduling
setTimeout. On success: 250 ms steady cadence. On failure for an
explicit backend: 250 ms → 500 → 1 s → 2 s → 4 s → 8 s → 16 s →
capped at 30 s. Resets to 250 ms the moment the backend comes back.
Auto mode (Pages with no backend) still disables network entirely
after the first 404. Strict-live mode (?live=1) also backs off so
it doesn't spam.
2. Show an actionable status banner in the info panel when the chosen
backend is unreachable: the URL, the actual error string, the next
retry time, and the exact `cargo run` command to start the server.
Visitor sees the diagnosis instead of staring at a 'demo' badge
wondering why their ESP32 feed isn't visible.
The scene keeps animating (face mesh / synthetic) while the viewer
waits, so the tab never goes blank.

Lets the visitor enable their browser webcam face mesh in addition to
(not instead of) a connected ESP32 backend. Both render in the same
Three.js scene — the live ESP32-driven splats from /api/splats plus the
visitor's own face as a 478-vertex MediaPipe point cloud. Use cases:
- Local development: see your face overlaid on the camera+CSI fusion
output to debug coordinate-frame alignment.
- Demos: show 'this is the room as ESP32 sees it, and this is me as
MediaPipe sees me' side-by-side in one scene.
Implementation:
- Extract pushFaceSplats(splats) — pushes the 478 face vertices plus
~8000 edge-interpolated samples into the array, with no Foundation
context. Reused by faceMeshFrame (demo path) and handleData (overlay
path) so there is one source of truth for face-splat geometry.
- handleData now appends pushFaceSplats output to data.splats when the
source is not 'face-mesh' AND the user has clicked the camera CTA.
Sets data._faceOverlay so the badge can show '+ face overlay'.
- Camera CTA is no longer hidden in remote/live modes — it relabels to
'▶ Add face overlay' so the affordance is clear. Strict-live mode
(?live=1) still hides it because the offline panel takes over.
- Splat count in the info panel reflects the rendered total (backend +
overlay) when the overlay is active.

The hosted GitHub Pages viewer can now act as a thin client for a
locally-running ruview-pointcloud serve instance — flip a button, the
ESP32's CSI fusion (camera depth + WiFi CSI + mmWave) renders inside
the same Three.js scene that previously only showed the face mesh
demo. No clone, no rebuild, no toolchain on the visitor's side.
Server (stream.rs):
- Add tower_http::cors::CorsLayer with a deliberate allowlist:
https://ruvnet.github.io, http://localhost:*, http://127.0.0.1:*,
and 'null' (for file:// origins). Anything else is denied — not a
wildcard CORS. Modern browsers (Chrome 94+, Firefox 116+, Safari
16.4+) treat 127.0.0.1 as a "potentially trustworthy" origin so
HTTPS Pages → HTTP loopback is permitted. The new layer wraps the
existing /api/cloud, /api/splats, /api/status, /health routes.
- Cargo.toml: pull in workspace tower-http (cors feature already on).
Viewer:
- New "📡 Connect ESP32…" CTA bottom-right. Clicking prompts for a
ruview-pointcloud serve URL (default http://127.0.0.1:9880),
persists the last-used value in localStorage, and reloads with
?backend=<url> so the existing remote-mode fetch path takes over.
When already connected the button toggles to "disconnect" and
reloads back to the demo.
- Reuses the existing transport selector — no new code path to
maintain. The face mesh / synthetic demo render path is unaffected;
this is purely an additive UI affordance over the ?backend= query.
Docs:
- ADR-094 §2.3 expanded with the local-ESP32 workflow and the CORS
posture rationale.
- Workflow README documents ?backend=http://127.0.0.1:9880 as the
intended local-ESP32 path.
Tests: cargo test -p wifi-densepose-pointcloud → 15/15 passed.

Browsers auto-request /favicon.ico when none is declared in <head>.
On a static GitHub Pages host that's a guaranteed 404 in the console.
Inline a 32x32 SVG amber dot via data: URL so the browser is satisfied
without an extra network round-trip.

When the viewer is hosted on a static origin (GitHub Pages, S3) it has
no backend at /api/splats. The default ?backend=auto path was issuing
a fetch every 100 ms, getting a 404, falling back to the demo, and
flooding the console with one 404 per tick. Cosmetic on the surface
but real network/CPU waste over time.
After the first 404 in auto mode, set networkDisabled=true and skip
fetch on subsequent ticks — the interval still fires but goes straight
to pickDemoFrame() so the face mesh / synthetic render path keeps
animating. Remote (?backend=<url>) and live (?live=1) modes keep
retrying so a transient outage doesn't permanently downgrade them.

Adds optional cinematic effects to the face-mesh demo, all toggleable
via a new ?fx= URL param. Default is 'all' (texture + mesh + scan +
halo). Lightweight modes available: ?fx=clean (texture only) or
?fx=points (original solid amber).
- Texture: per-frame webcam → hidden 2D canvas → getImageData lookup
at each landmark (and each interpolated edge sample). Splats now
carry the visitor's actual skin tone, not solid amber. Sampling is
mirrored on x to match the selfie convention used by the face mesh
vertex placement. All on-device — no frames leave the browser.
- Mesh: persistent THREE.LineSegments overlay drawn from
FACEMESH_TESSELATION (~1300 edges). Translucent (opacity 0.35),
amber, additive blending, depthWrite off — gives a holographic
wireframe wrapping the point cloud. Geometry is updated in place
each frame; only positions get re-uploaded.
- Scan: vertical bright slab sweeps top→bottom every 4 seconds,
amplifying splat color up to 2.6× when within ±0.08 world units of
the line. Westworld-style scanning.
- Halo: existing 60-particle ring around the face is now opt-in via
FX_HALO. Cleaner default for the texture-mesh combination.
Info panel surfaces active fx list in face-mesh mode. Synthetic
fallback hides the wireframe overlay so it doesn't render against an
empty figure. Workflow README updated with the new ?fx= options.

Three fixes in one pass to address visitor feedback:
1. Face was rendering upside down — MediaPipe's lm.y is image-down (0=top
of frame, 1=bottom) and the existing updateSplats() already does a
y-negate to convert to Three.js Y-up. Pre-flipping in lmToCenter was a
double flip. Use lm.y directly so the renderer's single flip lands the
head at the top of the screen.
2. Density and fidelity — interpolate 6 splats per FACEMESH_TESSELATION
edge (~1300 edges → ~8000 face splats vs 478 vertex-only). Amplify
lm.z mapping (×8 vs ×4) so eye sockets, nose, and chin show real 3D
depth. Smaller splat scale (0.006 surface, 0.010 vertices) for finer
point appearance.
3. Foundation-inspired aesthetic — the demo now renders the subject
(face mesh OR procedural fallback) inside a Hari Seldon time-vault:
* Holographic surveyor grid in amber, breathing brightness pattern.
* Slow-rotating two-arm galactic spiral receding behind the subject
(~640 stars, warm core to cool edges, Trantor-evocation).
* 800-star deterministic distant starfield on a spherical shell
(fixed LCG seed so visitors don't see noise flicker).
* 60-particle holographic halo orbiting the subject plane.
Shared pushFoundationContext() drives both face-mesh and synthetic
paths. Synthetic procedural figure densified 4x (240 vs 60 points)
and re-oriented (head→top, feet→bottom) so the y-down convention is
internally consistent.
Camera pulled back to (0, 0.2, -3.5) to frame the galactic context.
Poll cadence 4 Hz → 10 Hz so the spiral animates smoothly. Info panel
gets a Seldon quote and "Seldon Vault" branding. CTA copy reframed to
"Project Subject — render your face into the Vault".
ADR-094 already documents the dual-transport intent; the aesthetic
choices here are content, not architecture, so no ADR update needed.

The previous synthetic procedural demo did not represent what the local
fusion pipeline produces — a real depth-backprojected point cloud of
the user's face and surroundings. This commit ports the closest browser
equivalent: MediaPipe Face Mesh runs in-browser at ~30 fps and emits
478 3D landmarks per frame. Each visitor now sees the outline of their
own face rendered as a point cloud, with a small floor + back wall for
spatial context.
- Adds MediaPipe Face Mesh + Camera Utils via jsdelivr CDN.
- Adds an "▶ Enable camera" CTA so getUserMedia is gated on a user
gesture (required by some browsers and good UX regardless).
- New face-mesh frame generator uses the same splat shape as the live
/api/splats payload, so a single render path drives both modes.
- Mirrors x to match selfie convention; maps lm.z (relative depth) to
the world-coord range used by the live pipeline.
- Falls back automatically to the procedural floor + walls + figure
when the camera is denied, dismissed, or unavailable.
- Badge surfaces the new state: '● DEMO Your Face (MediaPipe)'.
- Bumps poll cadence to 4 Hz so face mesh updates feel live.
- ADR-094 updated to reflect the new default behavior.

Publishes the live 3D point cloud viewer to gh-pages/pointcloud/ so it
can be linked from the README alongside the Observatory and Dual-Modal
Pose Fusion demos. The viewer auto-selects its transport from URL
parameters:
- default / ?backend=auto — try /api/splats, fall back to synthetic demo
- ?backend=demo — synthetic in-browser only, no network
- ?backend=<url> — fetch from a CORS-permitting host running
ruview-pointcloud serve
- ?live=1 — strict mode, show offline panel instead of demo fallback
The synthetic frame matches the live API JSON shape (splats, count,
frame, live, pipeline.{skeleton,vitals}) so a single render path drives
both modes. New workflow uses keep_files: true to preserve the existing
observatory/, pose-fusion/, and nvsim/ deployments on gh-pages.
See docs/adr/ADR-094-pointcloud-github-pages-deployment.md for the full
decision record and 6 acceptance gates.
The Rust port lived two directories deep (rust-port/wifi-densepose-rs/)
without any sibling under rust-port/ that warranted the extra level.
Move the whole workspace up to v2/ to match v1/ (Python) at the same
depth and shorten every cd / build command across the repo.
git mv preserves history for all tracked files. 60 files updated for
path references (CI workflows, ADRs, docs, scripts, READMEs, internal
.claude-flow state). Two manual fixes for relative-cd paths in
CLAUDE.md and ADR-043 that became wrong after the depth change
(cd ../.. → cd ..).
Validated:
- cargo check --workspace --no-default-features → clean (after target/
nuke; the gitignored target/ was carried by the OS rename and had
hard-coded old paths in build scripts)
- cargo test --workspace --no-default-features → 1,539 passed, 0 failed,
8 ignored (same totals as pre-rename)
- ESP32-S3 on COM7 → still streaming live CSI (cb #40300, RSSI -64 dBm)
After-merge follow-up: contributors should `rm -rf v2/target` once and
let cargo regenerate from the new path.
