METROLOGY REPLAY LAB / SA-MET-GRR-001

A Gauge R&R number is not a measurement-system verdict.
Metrology / Yield

Study design, representative part range, repeatability, operator/tool/interaction reproducibility, bias, linearity, stability, resolution, uncertainty, and the supported claim must stay distinguishable. This replay keeps each evidence gap and next check visible.

EVIDENCE SEQUENCE

What the learner should inspect first.

This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.

01

Choose a crossed, nested, sparse-unbalanced, or confounded study design and a representative, narrow, mixed-family, or reference-artifact part-spread state.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
02

Keep repeatability separate from operator, tool/configuration, and operator-by-part interaction reproducibility before reading total Gauge R&R or discrimination proxies.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
03

Review bias, range linearity, stability/drift, resolution, reference lineage, uncertainty, accountable role, and the next owned evidence check outside any production acceptance rule.

METHODS

Precomputed model contract.

The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.

method

Every numeric field comes from an original deterministic 4 x 4 x 4 x 4 x 4 x 4 teaching sweep; no raw measurement or external example value is fitted or copied.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

Variance-component, percent-study-variation, discrimination, distinct-category, uncertainty-review, readiness, and priority values are direct labeled proxies; no ANOVA, REML, mixed model, Minitab run, or spreadsheet macro is executed.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

Local triage, backlog, factory proof, and resource-candidate records retain SHA-256 lineage in the canonical evidence folder.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

LIMITS

Useful, but deliberately bounded.

No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.

non-claim

No universal Gauge R&R acceptance band, percent-tolerance decision, customer specification, production threshold, quality disposition, lot release, qualification, calibration, or traceability claim.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

No live analysis, upload, metrology-system connection, APC/FDC action, equipment control, account, payment, comment, newsletter, job/event workflow, or public service intake.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

Real work needs owned raw repeats, stable representative material, declared crossed/nested design, randomization, gauge/operator/configuration identity, references, environment, analysis, uncertainty, and accountable review.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

SOURCE ANCHOR

Link-only public source spine.

SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
