Available tools

Case Exhibit Access Purpose Code Tool Record an explicitly supplied case-exhibit access purpose without authorizing access.
Chain Of Custody Timezone Order Check Tool Order explicit local-clock epoch-like timestamps after UTC-offset correction; this does not authenticate custody records.
Custody Clock Offset Gap Tool Compare deidentified custody event clocks under explicit offsets without asserting chain-of-custody validity.
Deidentified Case Linkage Salt Label Tool Record supplied case-linkage namespace and salt-version metadata without creating hashes, storing secrets or claiming anonymization.
Document Page Image Crop Offset Tool Page-to-crop coordinate translation followed by uniform scaling, retaining coordinates outside the crop as signed values.
Evidence Bag Nested Container Token Tool Encode an ordered supplied outer-container, inner-container and evidence key without asserting chain-of-custody validity.
Evidence Container Transfer Label Record explicit evidence-container transfer identifiers without verifying custody or integrity.
Evidence Package Seal Share Tool Count literal package/seal verification records; no chain-of-custody adequacy finding.
Evidence Retention Order Date Gap Tool Calculate signed calendar days between supplied retention-order and retention-end dates without interpreting legal duties.
Evidence Return Recipient Receipt Key Tool Link supplied evidence-return recipient and receipt identifiers without verifying transfer or authority.
Evidence Return Retained Quantity Balance Tool Calculate evidence return retained quantity balance from explicit caller-supplied inputs.
Evidence Scale Perspective Length Factor Tool Pinhole parallel-plane perspective scale correction using camera distances; arbitrary camera poses and lens distortion are not solved.
Evidence Seal Count Residual Tool Reconcile supplied disjoint evidence-seal inventory counts without authenticating custody or evidence.
Evidence Seal Identifier Compare Compare literal evidence-seal identifiers under an explicit case policy without authenticating a seal.
Evidence Subsample Retained Mass Tool Calculate evidence subsample retained mass from explicit caller-supplied inputs.
Evidence Volume Subsample Share Term Tool Homogeneity-based mass expansion with an explicit assumption flag, without a forensic sampling sufficiency claim.
Exhibit Bag Seal ID Pair Tool Exact or Unicode lowercase identifier comparison without trimming or punctuation removal; matching labels do not authenticate an exhibit.
Exhibit ID Check Token Tool Inspect a caller-defined public exhibit namespace without identity resolution or an invented checksum.
Exhibit Seal Version Match Flag Tool Literal supplied seal/version consistency only, without authenticity or evidentiary conclusions.
Exhibit Source Resolution Gap Tool Compare explicit source resolution requirements; no evidentiary reliability conclusion.
Exhibit Sub Sample Volume Balance Reconcile supplied exhibit subsample volumes, retaining signed deficits for record review.
Fiber Diameter Microscope Factor Tool Explicit projection correction along the measured width axis, assuming a foreshortening factor cos(angle); no fiber type is inferred.
Forensic Balance Tare Uncertainty Term Tool Net mass and first-order correlated standard uncertainty of a difference, without a coverage-factor expansion.
Forensic Blank Sample Subtraction Subtract an explicit analytical blank signal while preserving negative corrected results.
Forensic Case Redaction Marker Apply an explicit whole-field case-reference redaction switch without inspecting sensitive content.
Forensic Interlaboratory Reference Delta Tool Independent-uncertainty normalized interlaboratory difference, with matching uncertainty coverage conventions required.
Forensic Lab Blank Correction Term Tool Single linear blank correction preserving negative results; calibration intercept must already have been handled consistently.
Forensic Photo Scale Perspective Label Tool Preserve explicit forensic photo scale and perspective metadata without correcting geometry or interpreting evidence.
Forensic Reference Certificate ID Qualify an explicit reference-material certificate identifier without verifying certification or traceability.
Forensic Reference Expiry As Of Date Tool Measure signed calendar days to a supplied forensic reference expiry date without determining suitability or accreditation.
Forensic Report Conclusion Source Code Record a supplied conclusion code and codebook source without generating or interpreting a forensic conclusion.
Forensic Sample Dry Wet Mass Ratio Tool Calculate explicit dry-to-wet sample mass fraction and mass difference without identifying material or predicting stability.
Forensic Spectrum One Peak Ratio Tool Baseline-corrected peak ratio with explicit baselines, without a material-identification or likelihood interpretation.
Forensic Timestamp Resolution Interval Tool Construct an explicit truncation-style timestamp interval [reported, reported+resolution) without inferring clock accuracy.
Glass Refractive Index Repeat Gap Tool Two refractive-index observations with an explicit linear temperature correction, not a common-source conclusion.
Image Ruler Scale Parallax Term Tool Measurement arithmetic with a separately supplied image-plane scale correction, not a parallax estimate.
Inkline Width Calibration Pair Tool Pixel-to-length width with only the supplied reference-width uncertainty propagated.
Measurement Rounding Range Width Tool Report one nearest-rounding cell width with explicit endpoint membership; no measurement uncertainty is inferred.
Measurement Scale Photo Ratio Tool Compare supplied photographed ruler measurements without forensic identification or evidentiary conclusions.
Photographed Footwear Scale Length Term Tool Calibrated impression length with an explicit additional relative enlargement factor; no footwear-source or wearer inference.
Questioned Document Baseline Slope Term Tool Two-point baseline slope with radians measured in the supplied image-axis orientation, without handwriting attribution.
Questioned Document Line Spacing Convert two supplied baseline positions into signed and absolute line spacing without attributing authorship.
Questioned Line Width Unit Base Tool Convert a supplied line-width measurement using source-unit size in base units; no handwriting/source identification.
Witness Transcript Inaudible Span Budget Tool Disjoint inaudible and untranscribed duration accounting; no transcript reliability or testimony assessment.
