+# Greenroom — Deal Modeling Slice
+
+**To:** Pri (CEO), Anil (Product)
+**From:** Febin
+**Date:** May 2026
+**Re:** Why I picked Deal Modeling, what I built, what's next
+
+---
+
+## The slice
+
+From the six possible cuts inside settlement — *deal modeling, audit trails, real-time prediction, the 2am walkthrough, post-show comms, dispute resolution* — **I picked Deal Modeling.**
+
+Disputes at The Crescent aren't math errors. They're **truth errors**. There's no agreed-on version of the deal anywhere in the system.
+
+The data is unambiguous:
+- **22 of 540** past settlements are formally disputed
+- **5+** "paid" settlements carry unresolved disputed recoups
+- **8** deals have prose in `deal_notes_freetext` that contradicts the structured fields
+- **Daniel Hwang at WME alone** has 4 prior disputed marketing recoups across 4 different shows
+
+Three of four interview subjects say the same thing in different words. Sarah Kim: *"the deal was a ghost — Mariana had her notes, I had my email, Andrea had her recollection, and none of them agreed."* Mariana: *"most of the friction in the 2am conversation comes from things that were knowable on Wednesday."* Marcus: *"we're paying a tax on every poorly-written deal email we ever signed."*
+
+---
+
+## What I built
+
+**The Deal Brief** — a Wednesday-confirmed, structured representation of the deal that both parties have signed off on in writing **before the show**.
+
+Mariana pastes the deal email. The system extracts structured terms, flags ambiguous sentences with **computed dollar swings**, and surfaces contradictions against existing data (percentage drift, hospitality cap breaches, cross-show agent patterns). She sends one clarification email to the agent if needed, gets *"confirmed"* back, and locks the brief.
+
+The settlement page then reads from the brief — closing the **62.5% unsupported-deal gap** (vs deals, walkout pots, ratchets, % of net, door) as a *byproduct* of fixing the upstream truth problem, not because I built a better calculator.
+
+The Coastal Spell dispute would not have happened with this in place. The same one-sentence ambiguity (*"expenses capped at $2,500, marketing recoup of $900 against gross"*) would have surfaced on Wednesday March 9 with a computed $720 dollar swing. Mariana sends one email. Daniel replies "confirmed." Dispute prevented.
+
+---
+
+## Design choices
+
+- **Brief, not calculator.** The calculator was never the bottleneck — input ambiguity was. The brief gives the existing calculator richer typed inputs.
+- **`recoupPlacement` is a required field** (`inside_cap` vs `outside_cap`). The brief schema *forces* the decision the legacy schema let stay ambiguous. This single field would have prevented the Coastal Spell loss.
+- **Source of truth is the prose**, not the structured fields. Mariana already trusts the email; the brief structures it without asking her to re-enter anything.
+- **Three lifecycle states** — `draft → awaiting_confirmation → confirmed`. The settlement page reads only confirmed briefs. Drafts don't flip math.
+- **The clarification email is a deterministic template, not AI-generated.** Mariana's voice and her relationship with the agent — not the model's.
+
+---
+
+## What I cut (and why)
+
+| Cut | Why |
+|---|---|
+| Vs-deal calculator as a standalone slice | Solving math on contested inputs gives perfect-wrong answers. Wrong layer of the problem. |
+| Polished 2am settlement UI | Mariana said *"the math is the easy part."* Polish the symptom, miss the cause. |
+| Post-show agent PDF | Ships value only after a trustworthy brief exists upstream. Sequenced for "next." |
+| Dispute resolution workspace | Optimizes for the 5% tail event instead of preventing the 30% of pre-dispute friction. |
+| Artist health scoring, triage dashboards | Feature-wishlist drift. Not derived from the data or the transcripts. |
+| Receipt uploads, version timelines, comments, redesigned settle page | Each tempting. None defended by the data. |
+| Agent-side portal/login | Agents already reply by email — don't make them adopt a new product. |
+| Vector DB (Pinecone, Weaviate) | 540 vectors × 1.5KB = 800KB. SQLite BLOB + pure-JS cosine in 1ms. No infra needed at this scale. |
+
+---
+
+## AI used like a senior teammate
+
+The product uses AI for exactly two things: **extracting structured terms from messy prose**, and **detecting when a single sentence could be read two ways**. Everything else is plain code.
+
+The implementation is a 4-tier waterfall:
+
+1. **Tier 0 — regex parser.** Handles **72%** of real deals at **$0**. ~5ms, no network.
+2. **Tier 1 — local embeddings** (Xenova MiniLM-L6, runs in Node). Clones prior confirmed briefs when similarity ≥ 0.95. Otherwise supplies top-3 examples as few-shot to Tier 2.
+3. **Tier 2 — Groq Llama 3.3 70B (free tier, 30 RPM).** Handles ~15% of deals — the genuinely weird ones. Two passes: structured extraction + ambiguity detection.
+4. **Tier 3 — Mariana.** Manual entry/edit. Drafts never auto-confirm.
+
+Cross-show pattern detection is **pure SQL**, not LLM. Agent's prior disputed marketing recoups via `GROUP BY agent_id` over `json_each(recoups_json)`. The senior architect's instinct: don't use AI for a `WHERE` clause.
+
+**~80% of real deals never touch the LLM.** Steady-state cost at one venue: **free**. At Greenroom's 340-venue scale: roughly **$10/month/venue**. The whole system runs in the existing Next.js process — no vector DB, no Python service, no message queue. Provider is swappable via env var (Groq, Gemini, or Ollama local).
+
+---
+
+## How I'd validate
+
+Three checks, in order of cost:
+
+1. **Replay against history (one evening, no users).** Run the brief flow against the 22 disputed settlements. For how many would the ambiguity report have surfaced the contested sentence before the show? **Target: ≥70%.**
+2. **Shadow mode at The Crescent (4 weeks).** Mariana runs her normal flow; the brief generates in parallel and emails her a Wednesday digest she can ignore. Measure: how often does she act on it? Does her Friday settlement match what the brief predicted?
+3. **Co-pilot at one design-partner venue (8 weeks).** Brief is canonical; settlement flows from it. Leading metric: % of vs-deal settlements that go through the in-app tool instead of a spreadsheet. **Today: ~0%. Target: 40% by week 12.**
+
+**Headline KPI:** % of disputes in the next quarter that the brief either prevented (ambiguity caught on Wednesday) or flagged in advance (cross-show pattern fired before the deal email was even sent). **Target: 50% reduction in formal disputes within 90 days at the pilot venue.**
+
+---
+
+## What ships next (in leverage order)
+
+1. **Agent-side preview link.** Diego asked for this directly in his transcript: a read-only URL the tour manager opens on their phone during loadout. Same brief, different audience. ~2 days.
+2. **Brief↔settlement diff.** When the final settlement strays from the confirmed brief, show *why* and *which clause*. Closes the prevention loop.
+3. **Inline field edits.** `saveBriefEdits` is wired server-side; the UI just needs the inline-edit affordance. ~1 day.
+4. **Pattern memory expansion.** From *"this agent disputes recoups"* to *"this venue routinely under-budgets hospitality by 35%."* Addresses Marcus's margin-variance complaint.
+5. **Brief export to the agent's inbox.** Once the brief is trustworthy, exporting it as a clean PDF satisfies Sarah Kim's *"itemization-provenance-tone"* requirement by construction.
+6. **Lazy backfill of the 540 historical deals.** First touch after this ships, auto-extract the brief in the background. Builds the corpus and the AI flywheel.
+
+---
+
+## The headline
+
+**Disputes are not math errors. They're truth errors.** The Deal Brief is a Wednesday tool that turns a contested deal into a confirmed one before the show happens. The Friday-night ritual gets shorter because the Wednesday-afternoon conversation finally happens.

+# Greenroom — Deal Modeling Slice
-**Software for independent music venues.**
+**The Deal Brief: turning fuzzy deal emails into a confirmed source of truth before the show.**
-This is the starter codebase for the Greenroom Applied AI PM case study.
+Built by Febin as a case study response for the Greenroom Applied AI PM role.
---
-You're looking at a working but mediocre product. It's enough to feel real, but every workflow has gaps. **Your job isn't to fix everything — it's to pick a slice and design it well.** See your case study brief for full instructions.
+## What this is
-## Before you start
+The original Greenroom product had a settlement workflow that couldn't handle ~62% of real deals (Vs, percentage-of-net, door, walkout, ratchet). The deeper problem was upstream: deal terms in the email and the structured database fields rarely agreed, and there was no canonical version anyone could point to. The Coastal Spell dispute (`data/dispute-thread.md`) cost the venue $720 and an agent relationship over a single ambiguous sentence.
-You'll need:
+This branch ships **The Deal Brief** — a Wednesday tool that:
-1. **Node.js, version 20 or higher** — get it from [nodejs.org](https://nodejs.org/) (pick the LTS version). Verify with `node -v`.
-2. **Git** — most computers have it. Verify with `git --version`. If not, install from [git-scm.com](https://git-scm.com/).
-3. **A code editor.** [VS Code](https://code.visualstudio.com/) is great. [Cursor](https://cursor.com/) is what we'd reach for if we were doing this case study.
-4. **A GitHub account.** Free at [github.com](https://github.com/).
+1. **Extracts** structured terms from the deal email (regex first, AI only when needed)
+2. **Flags ambiguous sentences** with computed dollar swings (the Coastal Spell pattern)
+3. **Surfaces contradictions** against the existing database (percentage drift, cross-show patterns, etc.) — all in SQL, no AI
+4. **Confirms in writing** — Mariana sends one clarification email, gets "confirmed" back, the brief locks
+5. **Feeds the settlement engine** — closing the 62% unsupported-deal gap as a byproduct
-If you're on Windows, run all the commands below in **Git Bash**, **PowerShell**, or **WSL** — not the legacy Command Prompt.
+Read the [memo](MEMO.md) for the full design rationale.
-## Setup, step by step
-
-### 1. Fork this repo to your own GitHub account
-
-Click the **Fork** button at the top right of [https://github.com/samay-cbh/greenroom-starter](https://github.com/samay-cbh/greenroom-starter). You'll get a copy under your own username.
-
-> _Why fork?_ A fork is your own copy of the repo. You'll commit your changes there, and submit your fork's URL when you're done. We can see your commit history that way.
+---
-### 2. Clone your fork to your computer
+## Quickstart (under 2 minutes)
```bash
git clone https://github.com/YOUR-USERNAME/greenroom-starter
cd greenroom-starter
+npm install
+npm run dev
```
-(Replace `YOUR-USERNAME` with your actual GitHub username.)
+Open **[http://localhost:3000](http://localhost:3000)**. You're logged in automatically as Mariana Reyes, lead booker at The Crescent.
+
+### Optional but recommended — set an AI key
-### 3. Install dependencies
+The Deal Brief works without an API key (regex parser handles ~72% of deals, manual entry covers the rest). To unlock the LLM-powered ambiguity detection and extraction for unusual emails, set one of these:
```bash
-npm install
+cp .env.example .env.local
```
-This pulls down all the JavaScript packages the project needs. Takes about 60 seconds. You may see a few warnings — those are normal and safe to ignore.
-
-### 4. Start the app
+Then edit `.env.local`:
```bash
-npm run dev
+# Option 1 — Groq (RECOMMENDED — 30 RPM free, ~500ms inference)
+GROQ_API_KEY=gsk_...
+
+# Option 2 — Gemini (10 RPM free, ~2s inference)
+GEMINI_API_KEY=AIza...
```
-You'll see something like:
+Then restart `npm run dev`.
-```

+
+## How to use the Deal Brief
+
+The new product surface lives at **`/shows/[id]/brief`**. Get there from any show detail page via the green "Confirm the deal" banner.
+
+### The four-step workflow
+
+1. **Paste the deal email** into the textarea. Real emails from agents, exactly as written. (Subject line, signature, etc. all fine.)
+2. **Click Extract.** The page parses the email and shows:
+ - Structured terms (guarantee, percentage, expense cap, hospitality cap, bonuses, recoups with placement tags)
+ - **Ambiguities** — sentences with multiple readings + dollar impact
+ - **Contradictions** — findings from cross-checking the brief against the database
+3. **Send a clarification** (if needed). The page drafts a one-line email Mariana can edit. After the agent replies "confirmed", paste their reply into the agent-reply field.
+4. **Click "Confirm with agent reply"** (or "Mark as confirmed (manual override)" if you've handled it out-of-band).
+
+Once confirmed, the settle page at `/shows/[id]/settle` switches from the legacy calculator to the brief-backed calculator. Vs deals, walkouts, ratchets — all now work end-to-end. Every line of the worksheet shows its citation back to a brief clause.
+
+### Five lifecycle states
+
+| State | What it means |
+|---|---|
+| **No brief yet** | Show has no brief. CTA: "Confirm the deal before settlement." |
+| **Draft** | Brief extracted, not yet confirmed. Settle page still uses legacy data. |
+| **Awaiting agent reply** | Mariana sent the clarification, waiting on the agent. |
+| **Confirmed** | Brief is the source of truth. Settle page uses it. |
+| **Superseded** | A newer version replaced this one. Kept on file as v1, v2, etc. |
+
+---
+
+## How the AI is used (and not used)
+
+The system uses AI for exactly **two** tasks:
+
+1. **Extracting structured terms from messy prose** when regex isn't confident enough
+2. **Detecting ambiguity** — sentences that two careful readers could interpret differently
+
+Everything else is plain code. Cross-show patterns are SQL. The clarification email is a template (Mariana's voice, not the model's). The math is regular arithmetic. **The AI proposes; Mariana confirms; every time.**
+
+### The 4-tier pipeline
-✓ Ready in 1.2s
```
+Tier 0 — Regex parser ~5ms $0 72% of deals
+Tier 1 — Local embeddings clone ~50ms $0 +5% (near-duplicates)
+Tier 2 — Free-tier LLM ~2s free +15% (the weird ones)
+Tier 3 — Manual entry Mariana's time ~3% remainder
+```
+
+**~80% of real deals never touch the LLM.** Steady-state cost at one venue: **free**. At Greenroom's 340-venue scale: ~$10/month/venue.
-### 5. Open it in your browser
+### Where to get the API keys
-Go to **[http://localhost:3000](http://localhost:3000)**.
+| Provider | Sign up | Free tier | Cost note |
+|---|---|---|---|
+| **Groq** (recommended) | [console.groq.com/keys](https://console.groq.com/keys) | 30 RPM, generous daily quota | Llama 3.3 70B, ~500ms inference |
+| **Gemini** (alternative) | [aistudio.google.com/apikey](https://aistudio.google.com/apikey) | 10 RPM, 250 requests/day | Gemini 2.5 Flash, ~2s inference |
-You'll land on Mariana's home view at The Crescent. **Click "Where to start" in the sidebar** for an in-product orientation.
+Both require a Google account. Both are free to start. Groq is faster and has more headroom on the free tier — if you hit rate limits on one, fall back to the other.
-> **Tip:** Press **⌘K** (Mac) or **Ctrl+K** (Windows/Linux) anywhere in the app to open the command palette — search across shows and artists instantly.
+### Forcing a specific provider
+
+By default the system auto-picks: Groq → Gemini → Manual. To force one:
+
+```bash
+# .env.local
+AI_PROVIDER=groq # or 'gemini' or 'manual'
+```
+
+`AI_PROVIDER=manual` skips the LLM entirely — useful for cost-sensitive testing or when you want to demo without any key configured.

## How the data is shaped
-Twenty-four months of synthetic operational data, designed to feel like a real venue:
+24 months of synthetic operational data, deterministic from a fixed seed:
| Table | Approx rows | What it represents |
|---|---|---|
-| `shows` | ~540 | 24 months of shows. The app displays only past shows (more appear as days pass). |
-| `artists` | 59 | Mix of recurring (A-tier, 4+ shows) and one-off (D-tier) acts |
-| `agents` | 14 | Across WME, CAA, Wasserman, Paradigm, and independents |
-| `deals` | ~540 | One per show. Mix is flat ~33%, vs ~33%, % of net ~24%, door ~5%, % of gross ~4% |
-| `ticket_sales` | ~540 | One summary row per show, with realistic sell-through distributions |
+| `shows` | ~540 | 24 months of shows. Past + 60 days forward. |
+| `artists` | 59 | Mix of recurring (A-tier) and one-off (D-tier) acts |
+| `agents` | 14 | Across WME, CAA, Wasserman, Paradigm, independents |
+| `deals` | ~540 | One per show. Flat ~33%, Vs ~33%, % of net ~24%, door ~5%, % of gross ~4% |
+| `ticket_sales` | ~540 | One summary row per show |
| `comps` | ~1,900 | Comp tickets across 6 categories |
| `expenses` | ~2,900 | Sound, lights, hospitality, marketing, production, backline |
-| `settlements` | ~540 | All shows have settlement data. Past shows display it; future shows hold it until their date arrives. |
-
-A few things worth knowing:
-
-**The deal `notes_freetext` field is the truth.** The structured fields (`guarantee_amount`, `percentage`, `bonuses_json`, `expense_cap`) are filled inconsistently. Mariana enters deals as prose because the structured fields don't model the actual deals well. This mismatch is part of the realism.
+| `settlements` | ~540 | All shows have settlement data |
+| **`deal_briefs`** *(new)* | **0 at start** | **Briefs created by the new flow** |
-**Vs deals come in flavors.** About a third of Vs deals are "standard." The rest mix in walkout pots, tier ratchets, and vs-gross variants. The current in-app tool can't settle most of these.
+### A few things worth knowing
-**Settlements have a lifecycle.** The state machine runs draft → submitted → in_review → signed (or disputed) → revised → finalized → paid → voided.
+**The deal `notes_freetext` field is the truth.** Structured fields (`guarantee_amount`, `percentage`, etc.) are filled inconsistently. The brief flow reads the prose, not the structured fields — that's the design.
-**Recoups are categorized.** Settlement records carry a `recoups_json` field with line items in categories like `marketing`, `hospitality_overage`, `production_overage`. Each can be `agreed`, `disputed`, or `withdrawn`.
+**Vs deals come in flavors.** Standard, walkout pot, tier ratchet, vs-gross. The brief schema makes `vsFlavor` first-class so all four settle correctly.
----
-
-## A note before you start
-
-Real venue data is messy. Fields drift over time. Prose contradicts structured values. Statuses don't always match the underlying reality. Patterns hide across many shows that look unremarkable in isolation. **What the UI shows you isn't always what the data says — and neither is necessarily what actually happened.**
+**Recoups have a placement field.** New in the brief schema: `inside_cap` or `outside_cap`. This is the single field that would have prevented the $720 Coastal Spell dispute.
-We'd encourage you to read the data closely, query `data/greenroom.db` directly, and bring skepticism to anything that seems clean. The candidates we hire are the ones who notice that the surface-level view is incomplete.
+**12 deliberate data contradictions are planted** in `db/seed.ts:1051-1320`. The brief's contradiction-checks surface 9 of them. Try `npm run db:studio` and inspect the `deal_briefs` table after a few confirms.

-## Troubleshooting
-
-### "Command not found: npm" or "node is not recognized"
+## Submission
-Node.js isn't installed (or isn't on your PATH). Install from [nodejs.org](https://nodejs.org/), then restart your terminal.
-
-### "Port 3000 is already in use"
+- **Repo:** this branch — `Febin-deal-modeling`
+- **Memo:** [MEMO.md](MEMO.md)
+- **Loom:** [link]
-Something else is using port 3000. Two options:
+---
-**Stop the other thing first.**
-- Mac/Linux: `lsof -ti:3000 | xargs kill -9`
-- Windows: `netstat -ano | findstr :3000` then `taskkill /PID /F`
+## Troubleshooting
-**Or run on a different port:**
+### "Port 3000 is already in use"
```bash
+# Mac/Linux
+lsof -ti:3000 | xargs kill -9
+# Or run on another port
npm run dev -- -p 3001
```
-### "Module not found" or weird build errors
+### "SQLITE_READONLY_DBMOVED" error after `npm run db:reset`
+You ran `db:reset` while the dev server was still holding the old file handle. Stop the dev server with `Ctrl+C`, then `npm run dev` again. The error message in the brief page UI explains this when it happens.
-Your `node_modules` is probably corrupt or incomplete. Reset it:
-
-```bash
-rm -rf node_modules package-lock.json
-npm install
-```
+### Brief page shows "Manual mode" warning
+No API key is set. Either set `GROQ_API_KEY` or `GEMINI_API_KEY` in `.env.local` and restart the dev server, or proceed in manual mode — the brief page still works, you just enter terms by hand.
-### The database looks empty, or you broke the data while exploring
+### Rate limit errors during extraction
+Switch providers. If you're using Gemini (10 RPM), get a Groq key (30 RPM) and add it to `.env.local`. The system auto-prefers Groq when both are set.
-Reset the database:
+### Tier 1 clone doesn't fire
+You need at least one **confirmed** brief in the database for the embedding search to have anything to clone from. Confirm a brief on one show first, then try a similar email on a different show — similarity must be ≥ 0.95.
+### "I want to wipe all briefs but keep everything else"
```bash
-npm run db:reset
+sqlite3 data/greenroom.db "DELETE FROM deal_briefs;"
```
-This drops the SQLite file and regenerates 24 months of data. Takes ~5 seconds. Deterministic — same data every time.
-
-### Page looks ugly or buttons aren't visible
-
-Hard-refresh your browser to clear the CSS cache:
-- Mac: **⌘ + Shift + R**
-- Windows/Linux: **Ctrl + Shift + R**
-
-### "I want to see what's actually in the database"
-
+### Page errors out / "Module not found"
```bash
-npm run db:studio
+rm -rf node_modules package-lock.json .next
+npm install
+npm run dev
```
-Opens [Drizzle Studio](https://orm.drizzle.team/drizzle-studio/overview) at `local.drizzle.studio` — a visual table browser. You can also open `data/greenroom.db` with any SQLite client (e.g. [TablePlus](https://tableplus.com/), [DBeaver](https://dbeaver.io/), or `sqlite3` CLI).
-
-### Anything else
+### Reset to a completely clean state
+```bash
+# Stop the dev server first (Ctrl+C)
+npm run db:reset
+npm run dev
+```
-If you're stuck, email the hiring contact. We'd rather you ask than burn an hour fighting a setup issue.
+Deterministic — same seed data every time. Date-dependent shows (today + 60 days forward) will shift, but show IDs stay stable.
