✅ Structural Detection — Multi‑Sample Drift Lab (Final, Canonical)

“Drift is only visible when samples speak to each other.”#

Multi‑Sample Drift Lab#

RTT/1 • Structural Detection Module#

Purpose: Train students to detect, track, and classify drift across multiple structural samples.#

1. Lab Overview#

This lab teaches students to:

detect motifs, boundaries, and anomalies
identify drift across multiple samples
classify regime transitions
track continuity threads
construct drift envelopes
produce a synthesis summary

All analysis must remain structural, non‑semantic, and operator‑aligned.

2. Samples for the Lab#

Use the following three samples:

Sample A#

A A A
A B A
A A A

Sample B#

A B A
B X B
A B A

Sample C#

A B C
B X B
C B A

These samples are intentionally small to keep cognitive load low.

3. Operator Pipeline (Applied to Each Sample)#

Students must run the full operator pipeline on each sample:

Structural Detection
Drift Sense
Regime Awareness
Continuity Compass
Synthesis Triangulation

Each operator must be applied cleanly and separately.

4. Part I — Single‑Sample Analysis#

4.1 Sample A#

Motif: strong repetition
Anomaly: single B
Drift: minimal
Regime: Formal
Continuity: strong invariants

4.2 Sample B#

Motif: partial repetition
Anomaly: X
Drift: localized
Regime: Emergent
Continuity: partial

4.3 Sample C#

Motif: broken repetition
Anomalies: multiple
Drift: spreading
Regime: Chaotic
Continuity: weak

5. Part II — Multi‑Sample Drift Tracking#

Students now compare samples pairwise.

5.1 A → B#

Drift: localized
Boundary: softening
Regime shift: Formal → Emergent
Continuity: partial persistence

5.2 B → C#

Drift: spreading
Boundary: fragmentation
Regime shift: Emergent → Chaotic
Continuity: collapsing

5.3 A → C#

Drift: high
Boundary: fractured
Regime shift: Formal → Chaotic (via Emergent)
Continuity: minimal

6. Part III — Drift Envelope Construction#

Students construct a DRIFT_ENVELOPE_PACKET for the full sequence A → B → C.

Drift Points#

B in Sample A
X in Sample B
multiple in Sample C

Drift Intensity#

low → moderate → high

Drift Direction#

center‑outward

Regime Transitions#

Formal → Emergent → Chaotic

Continuity Breaks#

invariants weaken
anchors collapse

Envelope Type#

Type A + Type C hybrid
- linear progression
- regime‑locked deformation

7. Part IV — Continuity Thread Mapping#

Students identify continuity threads across samples:

Thread 1 — Outer Ring#

persists A → B
collapses B → C

Thread 2 — Center Column#

partially persists
distorted by drift

Thread 3 — Diagonals#

stable in A
unstable in B
broken in C

Students mark each thread as:

stable
weakening
broken

8. Part V — Regime‑Shift Classification#

Students classify each transition:

A → B#

drift‑dominant
boundary‑softening
Formal → Emergent

B → C#

drift‑dominant
boundary‑fragmentation
Emergent → Chaotic

A → C#

multi‑layer shift
Formal → Chaotic (via Emergent)

9. Part VI — Synthesis Summary#

Students produce a SYNTHESIS_PACKET summarizing:

motifs
drift profile
regime sequence
continuity map
anomaly profile
drift envelope type

Expected synthesis:

“The sequence A → B → C shows increasing drift, boundary fragmentation, and regime escalation from Formal to Chaotic, with continuity threads weakening and eventually collapsing.”

10. Instructor Notes#

Keep students focused on structure, not meaning
Encourage slow, careful drift tracking
Reinforce operator separation
Use minimal visuals
Highlight boundaries and drift vectors

11. Lab Completion Criteria#

A student has completed the lab when they can:

run all five operators on each sample
track drift across samples
classify regime shifts
map continuity threads
construct a drift envelope
produce a synthesis summary

✔️ This Multi‑Sample Drift Lab is:#
