Concepts & system design
60 min· read · map the mechanismR19 — HF Datasets
R20 — Model Cards
R45 — NIST AI 100-2 poisoning limits
Read the assigned sections; map the mechanism, threat model and trade-offs.

Project implementation
120 min· build · integrate · debugRevisit your training-data poisoning experiment (
M2) and RAG/vector poisoning controls (D5,D10). Tighten outlier/provenance checks and trigger-detection heuristics.Build, integrate, debug and improve the increment in the active project.
- 03
Security lab
60 min· attack your own systemTest a subtler poisoning/trigger variant; record exact detection sensitivity, false-positive rates, and the mathematical/practical limits of anomaly detection and retraining.
Test the abuse case, failure path, authorization bypass or resource limit.

Verification & evidence
30 min· test · record evidenceUpdated poisoning evaluation report and hardened
D5/D10tests.Add or run regression tests; record the 9-point evidence record.
- 05
Deliberate practice & Socratic review
30 min· explain aloud · update gapsAnswer the 8 Socratic questions without notes: What? Why? How? What if? Why not? How can I prove it? Where can it break? What have I learned?
Re-explain the hardest concept aloud, inspect one edge case, update the gap log.

R45checked 2026-11-11 - videoSamuel Albanie · 19 minAnthropic - AI sleeper agents?
A paper walkthrough of backdoored models that persist through SFT, RL, and adversarial training, including why adversarial training can teach a model to hide its trigger — directly relevant to why behavioural filters alone fail.
R45checked 2026-11-11 - videoAutomation Testing with Joe Colantonio · 26 minData Poisoning and Adversarial AI with Dr. Arash Rahnama
Covers where poisoning enters the pipeline, defensive controls, robustness, and detection tooling in sequence, ending on practical advice for building detection into the data path.
R45checked 2026-11-11 - articleRed Hat Developer · 12 min readBackdoors in LLMs: Why model scanning isn't enough
Explains why a clean scan says nothing about weights that were never malicious code, then covers activation probes as a runtime backdoor signal with their generalisation caveats.

The original model-card structure — intended use, limitations, training data, and disaggregated evaluation — which is the provenance record you cite when a poisoned or mis-scoped dataset is the root cause.
