Parts 3–5 — materials pack (Quantic VIDEO Architecture / Coding / Close)
Everything for the locked five-part talk (#97) after Meghna’s cafe demo.
Casting: Meghna Part 2 UX · Claude Part 3 Architecture (Variant B) · Hiren Part 4 Coding (Variant C). Talk spine: Part 2 UX/business (Meghna) · Part 3 architecture why/how · Part 4 coding why/how · Part 5 honesty/close. Same usecase, three depths: Part 2 UX = frontend view (what Meghna shows) · Part 3 Architecture = view behind it (HLDs + FE/BE flow) · Part 4 Coding = how it is actually implemented (forms/functions/FE/BE/API/DB).
Present decks (diagrams only): Part 3 · Part 4 · Part 5 — fullscreen click-through for recording.
| Clock (room) | Part | Who | This pack |
|---|---|---|---|
| ~3:30–6:30 | 3 Architecture (Variant B) | Claude Part 3 | Camera: natural script + natural VO + natural TTS · Compare: technical script + technical VO + silent + technical TTS |
| ~6:30–9:30 | 4 Coding (Variant C) | Hiren Part 4 | Camera: natural script + natural VO + natural TTS · Compare: technical script + technical VO + silent + technical TTS |
| ~9:30–10:00 | 5 Shared close | Shared | Camera: natural script + natural VO + natural TTS · Compare: technical script + technical VO + silent + technical TTS |
Prefer natural for camera. Keep technical silent + technical VO for post-mortem compare. Label: silent videos are PROTOTYPE / samples / rehearsal. VO-integrated clips are PROTOTYPE TTS (en-US-GuyNeural) — not teammate VO · not Quantic submit. Natural VO = PROTOTYPE TTS natural. Owner rule: camera spoken lines stay plain (no FR/NFR on camera). Technical spoken scripts may use FR/NFR IDs for compare. ID map: Parts 3–5 handoff mapping — not spoken on camera. Demo focus: cafe.artof.link = staging environment for the MSAIE project (temporary — not production forever). Avoid “weekend Lightsail staging” on camera. Architect deploy table (off-camera ops OK): Local vs AWS MSAIE staging — same React+JSX→Flask→Postgres; Vite/local Postgres vs Caddy→on-box Postgres (MSAIE staging, tip 73d202d, not a shared RDS); newsletter store-only. Also folded into Stack. Architect visuals (PROTOTYPE): HLD + Meghna FE/BE · Part 4 coding overview — prefer hld-local + hld-aws-msaie; freeze for static pages; booking GET /api/slots + POST /api/reservations; newsletter POST /api/newsletter store-only. Older hld-as-is / hld-aws-staging stay as history.

| Part 4 — natural script | Timed ~3 min Coding why/how — camera spoken (plain) |
| Part 5 — natural script | Timed ~30–60s close — camera spoken (plain + updated honesty) |
| Part 3 — technical script | Compare / post-mortem (FR/NFR IDs OK) |
| Part 4 — technical script | Compare / post-mortem (FR/NFR IDs OK) |
| Part 5 — technical script | Compare / post-mortem (FR/NFR IDs OK) |
| Handoff mapping | FR/NFR / probe map — not spoken on camera |
| Local vs AWS | Architect deploy table (what used · explanation · rationale · implementation) |
| Part 3 HLD + Meghna FE/BE | Local + MSAIE staging HLDs + Meghna FE↔BE flow (PROTOTYPE) |
| Part 4 coding overview | Forms → API → modules → Postgres (PROTOTYPE) |
| Developer system map | Stack, API, schema, FE/BE (tip 73d202d) |

2. Prototype videos (silent)
| Asset | Path / URL | Note |
|---|---|---|
| Part 3 Architecture | `clips/part3-variant-b-prototype-silent.mp4` (~180s) | Silent Variant B rehearsal. Reservations → staging HLD → Coverage boxes → sensors. PROTOTYPE, not Quantic submit. |
| Part 4 Coding | `clips/part4-variant-c-prototype-silent.mp4` (~180s) | Silent Variant C rehearsal. Freeze/CI → table/fail-closed → timezone/modules. PROTOTYPE. |
| Part 5 Shared close | `clips/part5-shared-close-prototype-silent.mp4` (~60s) | Silent shared-close rehearsal with updated honesty card. PROTOTYPE. |
Prefer live diagrams / Coverage for the real recording; use the silent prototypes only for rehearsal / VO timing.
PROTOTYPE — silent Parts 3–5 samples. Not the Quantic submission. Voice-over recorded take Unknown.
Recorded teammate VO: Unknown until Claude, Hiren, or a shared speaker records.
2b. Prototype videos (technical VO — PROTOTYPE TTS)
Label: PROTOTYPE TTS (en-US-GuyNeural) — not teammate recorded VO · not Quantic submit.
Mux / duration notes: Parts 3–5 VO notes. Silent *-silent.mp4 files stay in §2 and were not overwritten.
| Asset | Path / URL | Note |
|---|---|---|
| Part 3 Architecture | `clips/part3-variant-b-prototype-vo.mp4` (~180s) | Technical timed lines + silence pad to the silent cut. PROTOTYPE TTS. |
| Part 4 Coding | `clips/part4-variant-c-prototype-vo.mp4` (~180s) | Technical timed lines + silence pad. PROTOTYPE TTS. |
| Part 5 Shared close | `clips/part5-shared-close-prototype-vo.mp4` (~64.5s) | Technical close + last-frame pad to match VO. PROTOTYPE TTS. |
PROTOTYPE TTS — machine voice
en-US-GuyNeural. Not teammate VO. Not the Quantic submission.
Recorded teammate VO: Unknown until Claude, Hiren, or a shared speaker records. These TTS clips do not change that.
2c. Prototype videos (natural VO — PROTOTYPE TTS natural)
Prefer this pack for camera. Technical silent (§2) and technical VO (§2b) stay beside it for post-mortem compare.
Label: PROTOTYPE TTS natural (en-US-GuyNeural) — not teammate VO · not Quantic submit.
| Asset | Path / URL | Note |
|---|---|---|
| Part 3 Architecture | `clips/part3-variant-b-prototype-vo-natural.mp4` (~180s) | Architect why/how timed lines + silence pad. PROTOTYPE TTS natural. |
| Part 4 Coding | `clips/part4-variant-c-prototype-vo-natural.mp4` (~180s) | Coding why/how timed lines + silence pad. PROTOTYPE TTS natural. |
| Part 5 Shared close | `clips/part5-shared-close-prototype-vo-natural.mp4` (~60s) | Natural close + pad. PROTOTYPE TTS natural. |
PROTOTYPE TTS natural — machine voice
en-US-GuyNeural. Not teammate VO. Not the Quantic submission. Does not replace technical silent or technical VO.
Recorded teammate VO: Unknown until Claude, Hiren, or a shared speaker records. These TTS clips do not change that.
3. Voice-over
| Asset | Path | Status |
|---|---|---|
| Part 3 natural VO (camera) | Part 3 Variant B VO natural | Ready to record — architecture why/how, no FR/NFR on camera |
| Part 4 natural VO (camera) | Part 4 Variant C VO natural | Ready to record — coding why/how, no FR/NFR on camera |
| Part 5 natural VO (camera) | Part 5 Shared close VO natural | Ready to record — updated honesty, plain |
| Part 3 technical VO (compare) | Part 3 Variant B VO | Post-mortem (technical + plain twin) |
| Part 4 technical VO (compare) | Part 4 Variant C VO | Post-mortem (technical + plain twin) |
| Part 5 technical VO (compare) | Part 5 Shared close VO | Post-mortem (updated honesty) |
| Recorded teammate VO | — | Unknown until Claude / Hiren / shared records |
