Sanction Matrix¶
Decision table — instantiates Proportionality Calibration
Lists sanction levels by conduct category or severity. It is a mechanism under this archetype, not the archetype itself.
A Sanction Matrix is a fixed lookup grid that assigns one prescribed sanction level to each conduct category — and, where relevant, each occurrence number. You classify the conduct, count prior instances if the grid tracks them, and read off the sanction the table specifies. Its defining purpose, and the sharp line between it and its nearest twin, is that it outputs a point, not a range: the grid exists to make like conduct receive like treatment, prioritizing consistency and precedent over case-by-case tailoring. It is deliberately the more rigid instrument in this family — an enumerated penalty scale whose whole value is that two people committing the same categorized offense get the same answer regardless of who is deciding. That rigidity is a feature where even-handedness is the point, and a liability where cases that look alike on the grid differ in ways the grid cannot see.
Example¶
A university honor council maintains a Sanction Matrix for academic-integrity cases. Conduct is sorted into defined categories — unauthorized collaboration, unpermitted materials in an exam, plagiarism of a submitted work, fabrication of data — and each category maps to a prescribed sanction that also steps with prior findings. First-offense plagiarism of a graded essay: a failing grade on the assignment plus a transcript notation. Second offense in any category: course failure and a one-term suspension. Fabrication, any offense: suspension, with expulsion on repeat. A panel facing a confirmed first-offense plagiarism case looks up the cell and applies the specified sanction — not a band to choose within, but the level the matrix prescribes — precisely so that the next panel, months later, gives the identical outcome to the identical offense. When a prior case reached a different result for the same category, that divergence is itself the flag the matrix is built to prevent: it holds the current case to the precedent the grid encodes.
How it works¶
- Classify the conduct into a defined category. The input is a discrete offense taxonomy, not a multi-axis severity read; the grid's rows are conduct types.
- Count prior findings if the grid steps. Where the matrix tracks history, the occurrence number selects the column, so a second offense reads a higher fixed cell.
- Read off the prescribed sanction. The cell yields a specified level — one answer, not a range — which is what makes application consistent across deciders.
- Hold the case to the encoded precedent. Divergence from what the grid prescribes for like conduct is treated as an error to justify or correct, not a discretion to exercise.
Tuning parameters¶
- Category resolution — how finely conduct is sorted into distinct rows. Coarse categories are easy to apply but force unlike cases together; fine ones separate cases but grow the grid and its edge disputes.
- Occurrence stepping — whether and how steeply sanctions rise with prior findings. Steeper stepping deters repetition but can produce harsh second-offense jumps.
- Rigidity of prescription — whether a cell names an exact sanction or a tight ceiling-and-floor. Exact prescription maximizes consistency; a tight pair leaves a sliver of discretion.
- Precedent-lock strength — how hard a departure from the encoded level is to make. Strong locks guarantee even-handedness but can entrench a level that has aged badly.
When it helps, and when it misleads¶
Its strength is even-handedness made mechanical: it is the fastest way to guarantee that the same categorized offense yields the same sanction across time and across deciders, which is exactly what a system under fairness pressure needs, and its precedent lock is a genuine defense against arbitrary or favoritism-driven leniency.
Its failure mode is the mirror of that strength. A fixed grid enforces uniformity even where cases differ in ways it cannot represent — the hazard familiar from zero-tolerance and mandatory-minimum schemes, where a rigid penalty applied regardless of context produces outcomes widely seen as unjust.[1] The classic misuse is "proportionality theater": a matrix that looks objective simply automates whatever assumptions were baked into its cells, hiding the real judgment inside the category boundaries. The guarding discipline is to treat the grid as a consistency floor rather than a complete answer — pairing it with a documented-departure channel and periodic review of whether its fixed levels still fit the cases they are catching.
How it implements the components¶
response_scale— the enumerated ladder of sanction levels is an explicit response scale, rendered as fixed cells rather than advisory bands.precedent_comparator— holding each case to the level the grid prescribes for like conduct is a precedent comparison built into the tool, the source of its consistency guarantee.
It performs no graded, multi-axis severity_assessment, folds in no context_adjustment_factor, and defines no recurrence-driven escalation_threshold band — that context-sensitive mapping to a *range of proportionate responses is the job of its nearest twin, the Response Matrix, which shows a band where this grid prescribes a point.*

Editorial Notes¶
Form Classification¶
Form family: Rule, Policy & Commitment
Rationale: Sanction Matrix operates as a standing rule, threshold, contractual commitment, or policy constraint governing future conduct because it lists sanction levels by conduct category or severity. It is a mechanism under this archetype, not the archetype itself.
Independent corroboration: The frozen evidence defines Sanction Matrix as 'Lists sanction levels by conduct category or severity; It is a mechanism under this archetype, not the archetype itself', so its operative form is Rule, Policy & Commitment.
Nearest alternative: Decision, Gate & Allocation — Sanction Matrix includes features of a case-specific gate, selection, routing, prioritization, or resource disposition, but its defining operation is a standing rule, threshold, contractual commitment, or policy constraint governing future conduct.
Review outcome: Independent reviewer agreement; medium confidence.
Origin Attribution¶
Primary origin: Law & Governance
Origin pattern: Single lineage
Present-day reach: Multi-domain
Rationale: Conduct categories mapped to sanction severity are canonical legal and disciplinary-governance structures.
Related originating lineages:
- Organizational & Management Science — Workplace discipline materially adapts sanction matrices to institutions.
- Public Administration & Policy — Public administration, policy implementation, and program oversight supplies a parallel or contributing lineage for the mechanism's defining operation: lists sanction levels by conduct category or severity. It is a mechanism under this archetype, not the archetype itself.
Review resolution: Both blind reviewers agree that law_governance is the primary historical origin. Explicit reconciliation of alternate_origin_disagreement starts from reviewer_a's mechanism-specific evidence: Conduct categories mapped to sanction severity are canonical legal and disciplinary-governance structures. Reviewer A proposed alternates=organizational_management, origin_mode=single_lineage, domain_reach=multi_domain, and encyclopedia_synthesis=false; reviewer B proposed alternates=public_administration_policy, origin_mode=single_lineage, domain_reach=multi_domain, and encyclopedia_synthesis=false. The final record retains every independently supported alternate from either review (organizational_management, public_administration_policy) without an arbitrary cap, selects origin_mode=single_lineage to represent the combined lineage evidence, and records domain_reach=multi_domain and encyclopedia_synthesis=false. Present-day transfer is recorded as reach and is not treated as proof of historical origin.
Review outcome: Reconciled after independent review; high confidence.
