Developed index — Playbooks
Part hub for operational chapters: procedures under real constraints (spectrum law, market non-stationarity, cryptographic misuse). Archive playbooks keep checklists; this page holds theory → practice bridges and full references.
At a glance
- Playbooks assume you already skimmed the matching CS leaf (crypto, ML, EE).
- Primary failure modes: custom crypto, leaky backtests, unlicensed RF.
- Each playbook should end in a verification step (test, measurement, or peer review).
1. Map
| Playbook | Depends on | Failure mode if ignored |
|---|---|---|
| Cryptography | Cryptography, Cybersecurity | Homegrown ciphers; bad RNG; rolled certs |
| ML · Finance | General ML, Economy | Lookahead leakage; ignored costs; regime shift |
| Radio | Electrical engineering, Physics | Illegal TX; impedance mismatch; desense |
2. Developed content
2.1 Cryptography operations
Rule 1. Prefer standardised AEAD + TLS 1.3 stacks over novel constructions.
Rule 2. Threat-model before algorithm choice.
Rule 3. Key lifecycle is the product (generate, store, rotate, revoke).

2.2 Machine learning in finance
Definition (leakage). Using information in training or validation that would not be available at decision time.
Practice
- Walk-forward / purged CV (see López de Prado).
- Explicit transaction costs and latency.
- Regime diagnostics (vol clustering, correlation breaks).

2.3 Radio
Physics core. ; free-space path loss scales with and (Friis).
Practice. Antenna matching, noise figure, regulatory masks, SDR workflow.

3. Verification templates
| Playbook | Minimum verification |
|---|---|
| Crypto | Interop test vectors; certificate chain validation; dependency CVE scan |
| ML–Finance | Purged CV sharpe with costs; null/random baseline beats check |
| Radio | Spectrum analyser trace; SWR/match; license check before TX |
