Adds an ADR documenting the decision made in v2025.9 to replace "decision tree" with "decision table" — avoiding collision with the ML/statistics meaning of "decision tree" (supervised learning via recursive feature partitioning).

Changes

  • docs/adr/0014-use-decision-table-terminology.md — New MADR-format ADR (status: accepted, date: 2025-09-17) covering:
    • Why "decision tree" is ambiguous (conflicts with ML/OR terminology)
    • Three options considered: keep, switch, or use both with disambiguation
    • Rationale for switching: "decision table" accurately reflects the tabular CSV/JSON data model
    • Consequences, including that legacy references will be updated incrementally
  • docs/adr/index.md — Added ADR-0014 to the Accepted Records list

The ADR frontmatter date (2025-08-26) doesn’t match the PR description (2025-09-17). Please align the ADR’s date field with the intended acceptance/last-updated date (or adjust the PR description if 2025-08-26 is correct).

In this repo’s ADRs/template, the Chosen option: line consistently uses double quotes without additional nested quoting. Here it’s written as Chosen option: 'Switch to "decision table"', which is inconsistent and a bit harder to read; consider switching to the standard quoting format used in other ADRs (see docs/adr/_template.md).

Suggested change
Chosen option: 'Switch to "decision table"'
Chosen option: "Switch to decision table"

The PR description says three options were considered (keep, switch, or use both with disambiguation), but the ADR lists only two options under “Considered Options”. Either add the missing option(s) to the ADR or update the PR description so they match.
