3006 · Protocols and participants

Chapter 3 · Context beyond the registry

Carry an exact participant from a proposed protocol into its evidence graph without creating a new identity.

Open a workspace beside this lesson. Protected links keep their existing access gates; no new permission is granted by this course.

Why this matters

The chapter argues that identity alone does not supply workflows, semantics, provenance or authority.

An agent needs the relationship between a participant and a particular step, not just a catalogue name.

Step by step

01
Inspect the proposed run-step context
Screen or control: P3 selected step and participants tab
Why: The workflow is where an identifier acquires a specific proposed role.
How: Open the proposed run step and compare its definition GDTI with the participant IDs and exact directed assertion IDs.
What you should see: Separate step, participant and relationship addresses.
Verify: The occurrence pointer is not relabeled as a GS1 asset key.
02
Traverse and return
Screen or control: Open exact participant in P5; return to the same protocol step
Why: Continuity matters only if the receiver validates the precise references.
How: Follow one participant link, inspect its original record and incoming assertion, then return to the original step.
What you should see: Exact navigation with no name-based substitution.
Verify: The participant address and step definition match before and after navigation.

What is happening under the surface

A step definition, a participant and their directed assertion are three separate addresses.

Required role labels do not bind physical participants. A retained assertion can be inspected without being promoted to compatibility or execution permission.

Common mistakes

Joining a participant by a similarly named record.
Treating a source assertion as a tested or company-approved configuration.

The records an agent needs

The current public walkthrough demonstrates exact directed relationship traversal inside an authored sample. It does not run a protocol or establish a physical binding.

Pointers locate records; hashes pin bytes; lesson numbers locate teaching material. None substitutes for an applicable assigned GS1 identity.

Apply what you learned

Record one complete step-to-participant inspection trail.

Review your work against these checks

All three records remain distinct
The return link opens the same definition
No proposed edge is called a verified physical bond

Check your reasoning

Why is the directed step-participant assertion needed?

This answer stays in page memory, is cleared when you leave, and is not sent or recorded as certification, validation or authority.

Source and current boundaries

Chapter 3 · design principle. Adapted, anonymous teaching prose; not a quotation or independent verification of the author’s assertions.

The demonstrated operation is read-only context traversal. Cross-system orchestration and physical action still require their own implementation, validation and authorization evidence.

Current governance adds exact-source retention, unknown-state, disclosure, validation and scoped-authority safeguards. Those safeguards are not represented as quotations from the historical book.

Numeric lesson numbers are educational content locators, not GS1 identities. Linked public screens use an anonymous non-issued fixture; reading, retrieval and practice do not authorize physical/cloud execution or constitute model-weight training.
