+- **Tech basis:** an 8760 hourly profile (e.g. **Rajasthan**), CUF prorated (e.g. 21% → 19.28%), extended to **25-year** generation (leap-year Feb 29 reuses Feb 28 profile)
+- **Capex → funding waterfall:** component-wise capex, funded by a **debt + equity mix**, progressing in **phases**
+- **Solar & wind** scenarios with configurable defaults
+- **Land costs:** upfront **Land Lease (5-yr)** on a **per-acre** basis; acreage from DC capacity (~**2.5 × Solar DC** for fixed module, higher for tracker/wind)
+- **Inputs sheet** drives the model (e.g. Solar DC MWdc capacity) → outputs capex/funding/returns tables

-- Tiers: **free** vs **pro** (`families.tier`); free guardrails = 1 GiB storage / 2 members per family
+Free (1 baby, 1 GiB, 2 members) → **Pro** (2nd baby, more storage, 50 GB premium cap). Billing in **₹** via Razorpay; subscriptions, dunning, churn alerts, webhook health. `families.tier` + `isPaidFamily()` ([[Decision Log#TD-002]]).

+## Auth evolution (important nuance)
+Two phases appear across the history:
+1. **DB sessions** — bcrypt + `sessions` table + httpOnly `tia_session` cookie; `requireFamily()`
+2. **NextAuth v5** — Google OAuth (public) + magic link (invite-only); used by the marketing-era build
+Hardening sprint **H1** explicitly "replaced broken password hash." Treat auth as **migrating/hardened** — confirm the current source of truth.
+
+## DB hardening (sprint H2)
+- Non-superuser role **`tia_app`** (LOGIN, only SELECT/INSERT/UPDATE/DELETE — no DROP/CREATE/ALTER ROLE)
+- Separate `DATABASE_URL_SUPERUSER` for migrations only
+- Per-request **session context** `app.current_family_id` set in a transaction (`src/db/scoped.ts`) → foundation for **Row-Level Security (RLS)**
+
+## Memories vision pipeline (sprint G2)
+Photo is mandatory; a **vision model does the metadata heavy-lifting**: photo → vision caption/tags → `memories.vision_embedding vector(1536)` (pgvector, ivfflat index `memories_embedding_idx`). Requires the `pgvector/pgvector:pg18` image ([[Deployment Checklist]]).

+## A Letter to Every New Parent (excerpt — verbatim)
+> When we held our daughter for the first time, we felt a rush of love we never knew we were capable of—and alongside it, a fear we hadn't expected. Everything felt fragile. Everything felt new.
+>
+> In those early days, we wanted to capture every yawn, every gurgle, every tiny hand curling around our fingers. But the apps we tried felt cold and clinical, as though they had been built by people who had never stayed awake at 3 a.m. wondering whether their baby's cough sounded different from yesterday.
+>
+> When our daughter, Tia, was born, we made a silent promise: we would remember everything. We meant it completely. And within weeks, details were already slipping away—not the big milestones, but the small things. The exact weight on day five. The way she stretched when she woke up. The moment she first looked at us as though she knew who we were.
+>
+> We built Tia with the belief that **the earliest years of a child's life deserve extraordinary care.** Every decision we make, every feature we release, and every promise we keep comes from the same understanding: **small things matter.** Because one day, those small things become the memories we treasure most.
+
+**Signature:** *Built by parents. Inspired by our daughter. Made for families. — Yashika & Manohar*
+
+## A Note on Modern Families (theme)
+Raising a child in a **nuclear family**; grandparents & loved ones want to stay connected → Tia makes sharing precious moments easy **while keeping parents in control**.
+

 # 📖 Tia — Origin Story
-> *Reconstructed inference — confirm/rewrite. Nothing here is asserted as fact.*
+> **Verified — in the founders' own words.** The app is named after **Manohar & [[Family Overview|Yashika]]'s daughter — Viradhya, called "Tia"** (born **5 Sept 2025**). It exists to preserve a child's earliest memories. *"Built by parents. Inspired by our daughter. Made for families."*
 
-## The likely origin (inferred)
+## Why TIA Exists (verbatim)
-Tia is a **baby-tracking app** built by someone who ships fast and solves his own problems ([[Credit Analyzer]] for his finances, [[Whisper Hotkey]] for his workflow). The most parsimonious explanation: **Manohar became a parent**, found existing trackers lacking, and built the tool he wanted — then generalised it into a SaaS with family circles and billing.
+> TIA began with a promise.
+> When our daughter, Tia, was born, we wanted to remember everything—the tiny stretches, the sleepy smiles, the moments that felt too precious to forget. But we quickly discovered how easily those details fade, even when you're trying your best to hold on to them.
+> We built TIA to help families preserve those memories.
+>
+> Named after our daughter, Tia, the app reflects the values that guide us as parents: **care, patience, trust, privacy, and respect.** We believe your family's memories belong to your family—not advertisers, algorithms, or engagement loops. We believe technology should support family life, not compete for attention.
+> TIA isn't here to track your child. It's here to help you remember them.
+> As parents raising a child in a nuclear family, we also understood how much grandparents and loved ones want to stay connected. That's why TIA makes it easy to share precious moments with family while keeping parents in control.
+>
+> One day, when your child asks, "What was I like when I was little?", we hope TIA helps you answer with photos, stories, milestones, and moments preserved with love.
 
-Evidence pointing this way:
+## Why We Named the App Tia (verbatim excerpt)
-- Deep, opinionated feature set (feeds/diapers/sleep/vaccinations/growth/memories) — the lived problem of a new parent
+> We named this app after our daughter, Tia. Not because we wanted a monument to her... because the love we have for our daughter is the same care we bring to building this app every single day. When we choose **privacy over profit, patience over speed, and thoughtful design over endless notifications**, we are building Tia the way we hope to raise our daughter—with care, responsibility, and respect.
-- **Family circles** — built for *his* family to share, then opened up
-- The name **"Tia"** — likely personal/meaningful (a child's name? a term of endearment?)
 
-## ✍️ Confirm the real story
+## The seed moment (from "A Letter to Every New Parent")
-- [ ] Did becoming a parent trigger Tia? When?
+> ...within weeks, details were already slipping away—not the big milestones, but the small things. The exact weight on day five. The way she stretched when she woke up... Those tiny details felt irreplaceable, and yet they were already beginning to fade. **That realization became the seed for everything Tia is today.**
-- [ ] What does **"Tia"** mean / who is it named after?
+
-- [ ] What existing app frustrated you enough to build your own?
+> The full long-form letter lives in [[Tia - Brand & Copy]] (the writing *is* the product — keep verbatim).
-- [ ] First "this has to exist" moment?

-> Verified surface facts + prompts for the strategy you hold in your head.
+> **Verified** from the founder's homepage brief and brand copy.
 
-## What it is (verified)
+## The core positioning
-A **family baby-tracking SaaS**: log the essentials, track growth & vaccinations, keep photo memories, ask an **AI assistant**, and share with family via **circles**. Marketing site at `/`, app at `/home`. Indian market signals: ₹ pricing, `en-IN` lang.
+> **Tia is a digital heirloom — not a generic tracker.**
 
-## Positioning canvas (fill in)
+- **Emotional spine:** the lifelong **archive a child inherits**
-- **For** … *(new parents in India? globally?)*
+- **Rational backbone:** **privacy as preservation** — *"we don't sell your data — we preserve it"*
-- **Who** … *(struggling with scattered tracking / want AI help / want to share with family)*
+- **Market wedge:** **India-native** — **IAP (Indian Academy of Pediatrics) vaccination schedule** + **Telegram alerts**
-- **Tia is a** … baby & parenting companion
+- **Lead with** the heirloom promise, **not** "track sleep"
-- **That** … unifies logging + memories + AI insight + family sharing
-- **Unlike** … *(Huckleberry / BabyTracker / paper)* → see [[Competitive Landscape]]
-- **Tia** … *(your wedge — AI? family circles? privacy/self-hosted ethos?)*
 
-## ✍️ Prompts
+## Taglines & hero copy (verbatim)
-- [ ] One-line pitch?
+- "Your baby's story, **preserved for a lifetime**."
-- [ ] Primary persona & geography?
+- "Tia is a **digital heirloom** — not just a tracker. Every feed, every first word, every vaccination, archived in one private place your child will one day look back on."
-- [ ] The wedge vs. Huckleberry & co. ([[Competitive Landscape]])
+- Footer: "A digital heirloom for your baby. Every moment, preserved — privately."
-- [ ] Free → Pro conversion thesis?
+- CTA: "Get started — it's free" · "Free during early access. No credit card."
+
+## Values (the brand creed)
+**Care · Patience · Trust · Privacy · Respect.** Privacy over profit; patience over speed; thoughtful design over endless notifications.
+
+## Product principles (hard rules)
+- **"Ask Tia" AI** = parenting *logistics* + **honest limits**. It **defers all symptom/medical questions to a pediatrician** — that restraint is a **trust feature**. Never implies diagnosis. No pricing/"free" label attached to AI.
+- Say **"IAP schedule"**, never "WHO" (in marketing). *(Growth charts separately reference WHO standards.)* Never imply IAP endorses Tia.
+- Homepage `/` always renders the static marketing story (the story/vision is part of the product).
+
+## Marketing site structure (shipped)
+Hero (heirloom promise) → The problem (the 3am reality) → What Tia does (feature cards w/ concrete examples) → Founder story → The heirloom vision → Privacy & trust → Honest early-access proof → Final CTA. Plus **/about** (the long-form "Letter", "Keepsake" design) and **/blog**.
+
+## Design language — "Keepsake"
+Warm cream paper (`#f7f1e6`), marigold accent (`#c98a2b`), dusty-rose emphasis (`#b8503e`); fonts **Newsreader** + **Fraunces**; favicon 🌸. Authorship withheld until the end of the letter — payoff is "— Yashika & Manohar" + the baby's portrait in the P.S.
+
+## ✍️ Still open
+- [ ] Primary persona beyond "Indian new parents"?
+- [ ] Free → Pro conversion thesis (1 baby free; 2nd baby = Pro)
+- [ ] Defensible moat vs Huckleberry/BabyTracker → [[Competitive Landscape]]

+# 🌞 The 8760 Energy Simulation Model
+> An atomic concept note, distilled from Manohar's own explainer.
+
+## What "8760" means
+**8,760 = hours in a year** (365 × 24). An 8760 model builds an **hourly profile of expected solar generation for every hour of the year** — not daily/monthly averages.
+
+## Why hourly granularity matters (for project finance)
+- **Solar variability** — peaks at noon, zero at night
+- **Grid constraints** — hourly profiles reveal **clipping & curtailment** risk
+- **Revenue forecasting** — **time-of-day pricing** changes economics
+- **Degradation** — performance shifts hour-by-hour across the asset's life
+
+## Key inputs
+- Irradiance: **GHI, DNI, DHI** · temperature
+- System specs: module type, **tilt, azimuth**
+- Loss factors: soiling, shading, inverter efficiency
+
+## The method (Manohar's approach)
+**Python + Pandas** for flexible custom analysis, **validated against PVsyst** for industry credibility.
+
+> **Key takeaway:** *Never rely on simple capacity-factor estimates for serious project-finance work.* The hourly shape is where the risk (and the money) lives.
