## 1. Architectural Mission & Technical Stack

AI Credits Hub is an authoritative engineering metrology platform and valuation index for artificial intelligence developer compute, foundation model API allowances, academic verification pipelines, and cloud startup incubators.

- **Framework Architecture**: Astro 5.x (Static Site Generation / 0 KB Client Framework JS Baseline).
- **Runtime Performance**: Sub-50ms INP, LCP <= 0.7s, CLS = 0.000, 100% client-side privacy-first reactive computation.
- **Data Integrity SLA**: 24-hour update verification cycle via automated cURL test rigs and direct provider API documentation telemetry.
- **Privacy Standard**: Zero analytics trackers, zero external telemetry pixels, 100% ephemeral client-side localStorage state.

## 2. Core Mathematical Formulations & Schemas

### TC-01: Blended Token Valuation Formula
Models empirical multi-turn conversational developer workloads where prompt context heavily outweighs generative output:
$$\text{Blended Rate} (\$/\text{1M tokens}) = 0.75 \times P_{\text{in}} + 0.25 \times P_{\text{out}}$$
Where:
- $P_{\text{in}}$ = Base provider pricing per 1,000,000 prompt/input tokens.
- $P_{\text{out}}$ = Base provider pricing per 1,000,000 completion/output tokens.

### TC-02: Academic Degree Savings Amortization
Models student discount benefits across degree completion durations:
$$\text{Monthly Cost} = P_{\text{retail}} \times (1 - \text{Discount Rate}) = \$20.00 \times (1 - 0.50) = \$10.00/\text{mo}$$
$$\text{Annual Savings} = \$120.00/\text{year} \quad | \quad \text{4-Year Degree Savings} = \$480.00$$

### TC-03: Multi-Tool Developer Stack Amortization
$$\text{Total Monthly Stack Savings} = \sum_{i=1}^{n} S_i$$
Default calibrated stack: Cursor Pro ($10/mo save) + GitHub Copilot ($10/mo save) + Coursera Deep Learning ($20/mo save) = $40.00/mo ($480.00/year).

### TC-04: Academic Email Domain Verification Regex
Validates accredited academic institution top-level and second-level domain designations:
```regex
\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.(edu|ac\.[a-z]{2}|edu\.[a-z]{2})\b
```
- Matches: `student@stanford.edu`, `researcher@ox.ac.uk`, `dev@uni.edu.au`.
- Rejects: Generic consumer domains (`gmail.com`, `proton.me`, `outlook.com`).

### TC-05: Prompt Caching Amortization Formula
Models agentic IDE context window cost compression:
$$\text{Effective Cost} = (\text{Hit Rate} \times P_{\text{cached}}) + ((1 - \text{Hit Rate}) \times P_{\text{uncached}})$$
At a 65% cache hit rate with standard foundation models ($0.30/1M cached vs $3.00/1M uncached):
$$\text{Effective Cost} = (0.65 \times \$0.30) + (0.35 \times \$3.00) = \$0.195 + \$1.05 = \$1.245/\text{1M (58.5% net savings)}$$
