Colab now ships CUDA 13.0 (driver 580); CTranslate2 wheels are CUDA 12
so GPU init fails with 'unsupported device cuda:0'. Install
nvidia-cublas-cu12/nvidia-cudnn-cu12 and set LD_LIBRARY_PATH in the
install cell; transcription cell reports failures cleanly.
API smoke: api_keys.json stores only digests (raw key shown once), so
the notebook now captures RAW_KEY at creation and uses it for upload
instead of reading the digest file (fixes 401).
Cell 1 now detects an existing /content/luke_scribe/.git and runs
git fetch + checkout feat/full-platform + pull --ff-only instead of
rm -rf + clone, so re-running the notebook updates instead of wiping
local changes.
Colab 'python3 -m venv' fails with ensurepip error (no .venv created,
so every subsequent cell hit 'command not found'). Switch to system pip
(Colab standard) and run the API server via nohup background with log
fallback diagnostics.
CPU-only dev env verified via mocks; the notebook runs the full real
pipeline on Colab Pro T4: clone → ffmpeg/venv install → detect (GPU
capability tier) → 127 unit/integration tests → sample TTS (KO+EN
tech terms) → real faster-whisper transcription → hotword/postprocess
→ API smoke → benchmark.

Decisions: Validate the transcription core and benchmark gate before API, queue, and realtime work; preserve five expansion contracts.
Remaining: Build the benchmark dataset and implement detect/transcribe/bench.

Populate the previously-empty .omc/project-memory.json so teammates and
future OMC sessions inherit context: 4 user directives (SoT location,
greenfield/next-step, locked design decisions, measurement-gated residual),
3 notes (architecture, tech stack, env), and the decided tech stack.

Fold post-plan decisions into the spec and consensus plan:
- Q1 deploy HW: undecided/mixed → delegate to hardware-adaptive auto-sizing
- Q2 model strategy: collapse to single turbo model if P1 bench entity ≥95%
- Q3 cancellation: cooperative (segment-boundary) is sufficient; no hard-kill
- Q4 concurrency N: delegate to boot-time auto-sizing (AC-8 = ≤5s within auto N)
Recompute clarity with the deep-interview model (Goal 0.96 / Constraint 0.95
/ Success 0.95 → Total 0.954): ambiguity ~10% → ~5%. Residual is now entirely
measurement/code-gated (AC-4 R-WER baseline, hybrid→single confirmation,
CT2 GIL) — next lever is P1 bench, not further interview.
