Project implementation
120 min· build · integrate · debugComplete
D9: before any sensitive click/type action, capture a fresh screenshot, run OCR/visual target inspection, compare visual coordinates against DOM accessibility bounds to detect deceptive overlays/drift, and require parameter-bound human approval or emergency stop/human takeover (C6).Test deleting a user's record end-to-end across SQL primary storage, Qdrant/Chroma vector indexes, Redis/in-memory caches, and logs. Document exact deletion guarantees and unavoidable retention limits.
Build, integrate, debug and improve the increment in the active project.

Security lab
60 min· attack your own systemNo separate task text for this block on day 61 — the sourced work sits in the block above. Keep the time box.
Test the abuse case, failure path, authorization bypass or resource limit.

Verification & evidence
30 min· test · record evidenceD9coordinate-drift/overlay detection and emergency-stop tests + end-to-end cross-store deletion verification test.Add or run regression tests; record the 9-point evidence record.

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.

Documents boundingBox() and element screenshots, the API that returns the DOM accessibility geometry you compare against OCR pixel coordinates to detect overlay drift before a sensitive click.

Defines Identify-P, Govern-P, Control-P, Communicate-P and Protect-P, the lifecycle controls you cite when writing down deletion guarantees and retention limits for the record-deletion test.
R17checked 2026-11-11 - videoDave Ebbelaar · 25 minHow to Build Human-in-the-Loop for AI Agents (Practical Guide)
Implements approval gating and pause/resume around sensitive tool actions, the pattern behind parameter-bound human approval and emergency takeover before a destructive click or type.

Shows how invisible overlay frames make a user click something other than what they see, the deceptive-overlay class your pixel audit detects by diffing rendered pixels against DOM bounds.

Traces how one person's data spreads across weights, vector indexes, caches and logs, which is the map you follow when testing end-to-end deletion and documenting what cannot be erased.
