Root cause of the "4 people → 2 speakers" Meet call: the colored-border detector
read solid camera-off avatar tiles (orange "J", magenta "G") as active speakers
for the ENTIRE call. Those whole-call phantom spans dominated backend name
attribution, collapsing every remote voice onto one name — and the giant filled
bbox also swallowed screen-share text (WERUNBTC.COM ×49) as a speaker.
Validated against 9 real fixtures (harness over the real MeetAdapter):
Detection:
- FrameSampler.thinColoredPoints: coloured counterpart of thinWhitePoints — keeps
thin border/ring/pill edges, drops solid colour fills.
- GridCallAnalyzer.isHollow: reject a highlight component whose interior is filled
(a solid tile) vs a hollow ring (a real border). Config.maxInteriorFill (0.2 default).
- MeetAdapter: detect thin BLUE edges only (hue 180–240°, measured from the
fixtures), maxInteriorFill 0.3 (real Meet rings ≈0.2–0.3, solid tiles ≈0.36).
- Result on fixtures: John Arnold/Grant Gilliam (solid tiles) now NEVER detected;
Matt Odell/Mark detected when their blue cue is present. Sparse but never wrong —
correct for a naming hint over audio diarization.
OCR name hygiene:
- isLikelyName rejects domain-like screen-share text ("WERUNBTC.COM", OCR'd ".GOM").
- cleaned() strips trailing punctuation ("Mark." → "Mark").
- TimelineBuilder.canonicalizeByFrequency folds rare OCR misspellings into a
dominant near-twin name ("Matt Odel"/"MattOdell" → "Matt Odell", "Mare" → "Mark").
Tests: hollow-ring, extended OCR filter, fuzzy-merge. 65 pass.
Ten31 Transcripts
Native macOS menu-bar app that auto-detects conference calls, records local audio,
builds a visual-derived speaker timeline, and hands audio + timeline to the
SparkControl backend for naming/transcription. See docs/ for the full spec.
This repo is at Phase 0 (scaffold, permissions, backend health check).
One-time setup
- Install Xcode from the Mac App Store (free; ~40 GB). Open it once and accept the license prompt.
- Install XcodeGen (generates the Xcode project from
project.yml):brew install xcodegen - Generate the project:
This creates
xcodegen generateTen31Transcripts.xcodeproj(git-ignored — regenerate any time). - Open it:
open Ten31Transcripts.xcodeproj - Signing is preconfigured:
project.ymlsetsDEVELOPMENT_TEAMto the free personal teamBK4Y6CXN35with automatic signing, so Signing & Capabilities should already show the team — no manual selection needed. (If you ever sign with a different Apple ID, updateDEVELOPMENT_TEAMinproject.yml, not in Xcode —xcodegen generateoverwrites Xcode-side changes.) - Press Run (⌘R).
Note: after adding files in a new phase, re-run
xcodegen generateand let Xcode reload the project. The signing team persists because it lives inproject.yml, so macOS permissions stay granted across rebuilds.
What Phase 0 does
- Launches as a menu-bar-only app (no Dock icon).
- Menu panel shows live status for the three permissions it needs — Microphone, Screen Recording, Accessibility — with Grant / Open Settings buttons.
- Shows a backend health check (
GET /api/status) against the configured host. - Settings: backend base URL, skip-TLS toggle (on by default for the self-signed cert), output folder, and adapter toggles (inert this phase).
No audio capture, call detection, screen reading, or backend hand-off yet — those
arrive in Phases 1–6 (docs/04_BUILD_PLAN.md).

Notes
- App Sandbox is off and Hardened Runtime is off — this is a personal, LAN-only tool that must observe other apps. Revisit only if distributing.
