Experience Is Not a Static Answer, but Extracting How to Investigate from Past Docs

Senior engineers and historical 8D / handover Slides record what to confirm first, which data cannot be directly compared, when to gather additional evidence, and when to bound a root cause. Structuring these scattered documents into versioned files prevents knowledge loss from engineer turnover and accelerates triage when the ~80% of recurring historical issues reappear.

White-box architecture means key choices, historical precedent citations, tool queries, inputs, calculations, and evidentiary links are auditable; it does not display hidden model activations, nor does it guarantee every judgment is automatically correct.

    SpecHistorical 8Ds, Technical PDFs, Handover Slides, and Process Specs

    Continuously parse historical post-mortems and newly added field reports into reusable anomaly signatures and triage logic.

    Specify operational scope, required inputs, conditional branches, and forbidden inferences.

    PlanExecute grounding with current operational data

    The Agent evaluates methods and capabilities within Rails, documenting identified gaps and selection rationales.

    Execution occurs only upon approval; diagnostic reports derive strictly from executed run outputs.

Five Dimensions for Reusable Engineering Methods

DimensionWhat Must Be PreservedWhy It Is Valuable
Applicable ScopeProcesses, Materials, Equipment, and PrerequisitesAvoid Applying Experience to the Wrong Scenario
Data RequirementsIdentity, Units, Quality, Versions, and Missing-Data HandlingFirst Confirm Whether the Check Can Be Performed
Checks & MethodsStandard procedures, method selections, and supplementary criteriaPreserve proven workflows while accommodating necessary adaptations
Decision BoundariesSupporting/opposing evidence, alternative hypotheses, and abort criteriaPrevent elevating statistical correlation to proven root cause
Review & ValidationVersions, Owners, Positive and Negative Cases, and Change RecordsContinuously verify that method specs remain empirically valid

Rails do not assign an isolated node to every individual field or API call; a Rail centers on a cohesive engineering judgment, and multiple Rails can shape a plan section.

Declarative Methods Do Not Mean Hard-Coded Scripts Dictate Everything

Advanced: Distinct Architectural Objects in the Current Platform

Expertise Graph stores reusable methods and dependencies; Session Graph tracks instance facts, choices, and gaps; Plan projects results into human-reviewable proposals. Kernel manages bindings, constraints, scheduling, and assembly; Agent provides reasoning within reviewed bounds; and specialized tools execute observations and computation.

Execution and post-run reports follow grounding. Calculations execute via validated tools, but computational determinism does not guarantee semantic correctness. Method governance and production deployment require formal engineering review and acceptance protocols.

Method validation begins with standardized benchmarks, boundary testbeds, and confirmed normal baselines, supplemented by historical excursions. Teams evaluate false negatives, false alarms, out-of-scope misapplication, and missing-data policies; testing scale reflects task risk.

WAFERPILOT / APPLICATION TO THIS TOPIC

Applying Method Specs to Reviewable Investigation Planning

WaferPilot Grounding combines reviewed methods with current data and capability descriptions to form a Plan containing check choices, reasons, parameters, limitations, and items awaiting confirmation. Engineers can modify or approve it; subsequent reports describe actual execution and results.
