Competency level

Foundation

Name the variables, units, artifacts, and evidence classes required to read the role path.

1.1

Identify inventory balance

Identify admission, storage, conductance, wall release, pumping, and removal terms in a bounded gas inventory.

Prerequisite: Start here
Evidence boundary: The inventory model is not a chamber recipe or operating envelope.

Public artifact tasks

lessonVacuum and gas inventoryName the inventory terms and their displayed units.mapEquipment and facilities domainLocate the equipment evidence lane and its safety boundary.

1.2

Separate signal, state, and control

Separate a raw signal, inferred equipment state, control action, and required measurement evidence.

Prerequisite: Identify inventory balance
Evidence boundary: Signal classification does not authorize automatic control or disposition.

Public artifact tasks

lessonSensor, metrology, and controlClassify each stage in the public sensing chain.referenceEvidence guideCheck whether each stage is observed, derived, or proxy evidence.

Competency level

Cross-domain practice

Trace and compare bounded public replays across at least one engineering handoff.

2.1

Compare inventory states

Compare two vacuum and gas-delivery replay states and attribute the displayed inventory difference to an explicit term.

Prerequisite: Separate signal, state, and control
Evidence boundary: The replay is synthetic teaching evidence and cannot determine an equipment setpoint.

Public artifact tasks

simulationVacuum and gas evidence mapSelect two fixed states and record the changed term.labVacuum and gas labCheck the balance and evidence boundary.

2.2

Trace a sensor chain

Trace a sensor value through measurement, chamber-state inference, and control decision while marking uncertainty.

Prerequisite: Compare inventory states
Evidence boundary: The path does not validate a controller, fault diagnosis, or equipment action.

Public artifact tasks

simulationSensor-control evidence atlasFollow one signal through the displayed evidence chain.labSensor-control labRecord uncertainty and missing replacement evidence.

Competency level

Evidence-ready

Construct an inspectable evidence record with limitations, stop conditions, and replacement needs.

3.1

Construct an equipment evidence packet

Construct a bounded equipment evidence packet with signal, state, metric, uncertainty, limitation, and escalation fields.

Prerequisite: Trace a sensor chain
Evidence boundary: Packet completeness is structural and does not establish calibration or operational readiness.

Public artifact tasks

workspaceEvidence provenanceRecord artifact and release lineage.sourceSource policyCheck access, rights, and citation status.

3.2

Document the operation boundary

Document why a public replay cannot support maintenance, safety, interlock, recipe, or setpoint decisions.

Prerequisite: Construct an equipment evidence packet
Evidence boundary: Operational decisions require approved procedures, qualified data, and responsible personnel outside SemiAgora.

Public artifact tasks

releaseRelease ledgerVerify the exact public artifact release.trustCorrectionsRecord a public boundary correction when needed.

Role boundary

Evidence first. Career promises stay out.

This path teaches evidence structure only and provides no recipe, maintenance, interlock, EHS, or equipment operating instruction.

Role paths are educational navigation. They do not certify competence, promise employment, rank candidates, or represent employer acceptance.
