Software & Source Code
The relevant software version follows from the technical question and event date; commit, branch, tag, release label and build artefact are related identifiers but not interchangeable evidence of the same state. The English version preserves the technical distinctions and limitations of the reviewed German V1 source.
Short answer
The technical examination focuses on selecting the software state that corresponds to the event and technical question rather than defaulting to the newest available version.
The conclusion remains limited by moved tags, mutable references, missing deployment evidence and reconstructions that cannot establish historical identity uniquely and is not a substitute for legal evaluation.
1. Determine the question and relevant time
Scope and technical proposition
The examination begins by fixing the proposition and the concrete state to which it applies. In this article the central task is selecting the software state that corresponds to the event and technical question rather than defaulting to the newest available version. The system boundary, relevant date and version identifiers are recorded before individual findings are interpreted, because a technically correct result about the wrong state cannot answer the intended question.
The scope also records explicit exclusions and dependencies. This prevents later expansion from a narrow reproduced observation to an entire product, project or historical period. The working question is written so that a knowledgeable reviewer can understand what evidence could support it and what evidence could weaken it.
2. Resolve repository references to concrete objects
Evidence and provenance
The examination basis is built from event time, Git revisions, branches, tags, release records, build logs, artefact hashes, deployment records, configuration and dependency state. Each item is identified with the strongest practical version, provenance and time information available. Originals, exports and working copies remain distinguishable, and transformations or filters are recorded where they can influence the conclusion.
Evidence quality is assessed separately from evidence existence. A file can be intact yet incomplete, a repository can be authentic yet shallow, and a log can be correctly exported yet unsuitable for a proposition outside its retention period. Missing expected evidence is recorded as a limitation rather than silently treated as confirmation.
3. Distinguish release, source and build
Reproducible examination
The technical method is to resolve repository references to immutable objects and connect source, build and deployment evidence to the relevant event. Commands, tools, parameters, thresholds and environment conditions are documented where they materially affect reproducibility. The objective is not merely to obtain a result but to preserve the reasoning path from identified input to technical finding.
Where the procedure contains judgement, the report states which parts are mechanical and which require professional interpretation. A repeated test or independent check is used where it can reveal sensitivity to configuration, tool choice, sample selection or an alternative technical mechanism.
4. Document artefact identity and hash relationships
Counter-checking and uncertainty
Counter-checking asks what else could produce the same observation and what result would contradict the preferred explanation. This is especially important because moved tags, mutable references, missing deployment evidence and reconstructions that cannot establish historical identity uniquely. Negative evidence is only given weight when the search space and detection capability are understood.
If several explanations remain compatible with the available material, the conclusion is not forced into a single cause. Instead, the report ranks or describes the support for each explanation and records which additional evidence would be needed to distinguish them.
5. Document a reproducible examination state
Reference and interpretation
Interpretation connects the finding to its technical significance, while assessment uses the acceptance, delivery, defect, incident or change event that defines which state is relevant. The reference, its version and its applicability are disclosed before the observed state is classified. This allows a reviewer to see whether disagreement concerns the measurement, the interpretation or the chosen criterion.
The assessment remains limited to the technical reference. A standard, specification, project requirement or repository convention may structure the technical comparison without automatically establishing contractual effect, legal responsibility, ownership or regulatory compliance.
6. Separate statement boundaries and legal evaluation
Synthesis and statement boundary
The final synthesis returns to the original question and states which parts are directly supported by evidence, which depend on interpretation and which remain uncertain because of moved tags, mutable references, missing deployment evidence and reconstructions that cannot establish historical identity uniquely. The wording is calibrated to the evidence rather than to the desired certainty of the dispute.
The statement boundary is therefore an affirmative part of the result. It identifies unexamined states, missing records, unresolved counter-hypotheses and legal or normative questions that require a different assessment. This makes the technical conclusion reviewable and reduces the risk of overclaim.
Is the technical conclusion sufficiently supported?
- Is the concrete subject and relevant state identified for which software version should be examined??
- Are the main evidence sources and their provenance documented?
- Are versions, dates, configuration and transformations recorded where they affect the result?
- Is the examination method reproducible enough for independent review?
- Were plausible counter-hypotheses or alternative explanations tested?
- Is the technical reference or comparison criterion explicit?
- Are missing evidence and method limitations stated as uncertainty?
- Are technical findings kept separate from legal or contractual evaluation?
Constructed example
A production incident occurred before a tag was moved. Deployment logs and an artefact hash identify the incident-date build, so the examination uses that build rather than the current target of the tag.
The example is entirely constructed and does not describe a real engagement, court appointment or client matter.

Critical review and methodological limitation
The evidential strength of this examination depends on event time, Git revisions, branches, tags, release records, build logs, artefact hashes, deployment records, configuration and dependency state. A precise-looking output cannot compensate for an unidentified version, incomplete provenance or a reference that does not apply to the state under examination.
A robust report therefore exposes the transition from finding to interpretation and shows where moved tags, mutable references, missing deployment evidence and reconstructions that cannot establish historical identity uniquely restrict the conclusion. Alternative explanations are retained when the evidence cannot distinguish them reliably.
- Identify the subject before interpreting evidence.
- Use the strongest source appropriate to the proposition.
- Document counter-evidence and missing evidence.
- State only what the method and evidence support.
