Week 7 · Five disciplines · One verified channel
A mountain beacon is almost lost inside the storm. Find its pulse, protect its code, place a relay, define the handshake, and open a channel that never mistakes silence for success.
Wave patterns separate signal from noise. Code checks reveal damage. Terrain controls the path. A shared protocol defines acknowledgment and failure. The final decision connects all four.
20 minutes
Physics · Waves, patterns, and noise
Distinguish a repeating signal from noise using pattern, timing, and repeated observations rather than loudness alone.
Make
A signal evidence strip
Story handoff: The rescue team confirms a weak repeating pulse. To prevent a copied message from changing as it crosses the storm, the coders need a simple way to detect an error.
25 minutes
Coding · Error detection and binary data
Trace a compact error-detection rule and distinguish detecting an error from correcting it.
Make
A error-check trace
Story handoff: The message can now carry an error check and a request to resend. The team still needs a relay point with line of sight to both the valley receiver and the hidden beacon zone.
25 minutes
Geography · Elevation and line of sight
Use elevation profiles and practical constraints to choose a relay site without assuming the highest point is automatically best.
Make
A relay-site profile
Story handoff: Lantern Pass gives the rescue message a defensible route. Now every sender and receiver must use the same sequence so silence, damage, and acknowledgment cannot be confused.
25 minutes
Communication · Protocols and ambiguity
Write an unambiguous communication protocol with ordered states, acknowledgment, timeout, and bounded retries.
Make
A rescue handshake protocol
Story handoff: The rescue network can now tell delivery from silence and corruption. The final council must combine signal evidence, code integrity, geography, and protocol states into one launch decision.
25 minutes
Systems reasoning · Evidence and rescue decisions
Synthesize physical, computational, geographic, and communication evidence into a testable operational decision.
Make
A mountain signal protocol
Story handoff: The first verified acknowledgment returns through the snow. The channel opens not because the storm vanished, but because every uncertainty now has a check, a state, or a stopping rule.
Attempts stay on this device. Finished work stays finished, and the family portfolio shows only evidence the learner actually completed here.
