Pull request overview
Refactors several oversized script files into smaller, single-responsibility modules while keeping existing import paths working via barrel re-exports (notably for data-transformers and weekly-review generation).
Changes:
- Decomposes
weekly-reviewgeneration intotypes,data-loader,analysis,generator, andvalidationmodules with a barrel export. - Splits
content-generatorsandconstantsinto focused sub-modules and adds shared helpers/barrels. - Adds “reference sub-modules” for browser IIFE dashboards and updates config globs/excludes (TypeScript + Knip).

declare const d3: any; and import * as d3 from 'd3'; conflict in the same module (duplicate identifier) and also mix “browser global” vs “module import” approaches. Pick one approach: either import d3 (for typing) or use global declarations, but not both.

This module references CONFIG, CommitteeDefinition, ProductivityMatrixRow, etc., but only imports CommitteeData. As written, it won’t type-check/compile if included. Import CONFIG from ./data.js and the missing types from ./types.js (or remove these type annotations if the intent is “reference-only” code).

This file uses d3.SimulationNodeDatum, d3.SimulationLinkDatum, and d3.DSVRowString in type positions, but only declares const d3: any. That does not create a d3 type namespace, so TypeScript will error if this file is ever type-checked. Prefer importing the needed D3 types (e.g., import type { SimulationNodeDatum, SimulationLinkDatum, DSVRowString } from 'd3') and reference those directly.

context (and the fallback label) is inserted into HTML without escaping. Since this content originates outside this function (data pipeline / API), it should be passed through escapeHtml(...) before embedding to avoid breaking markup and to reduce XSS risk.

event.description / event.details are interpolated directly into a <p> without escaping. If these strings contain </& (or worse, HTML), they can break markup or introduce XSS in generated pages. Please escape or sanitize these fields before embedding in HTML.

The contentStart calculation’s non-tillMatch branch always returns 0 (both ternary outcomes are 0), which makes the expression redundant and hard to follow. Consider removing contentStart entirely and handling the tillMatch vs fallback trimming directly in cleanedSummary.

There are stray lines starting with * (without an opening /**) which makes this file invalid TypeScript (parse error). This also looks like a partially deleted JSDoc block. Please either remove these lines or wrap them in a proper comment block so the file can be parsed/type-checked.

dayName can come from event.dayName (untrusted input) and is interpolated into the <h3> without HTML-escaping, enabling XSS injection in generated articles. Escape dayName (or build the prefix using escapeHtml(dayName)) before concatenating into the heading.

scales.x.type is set to 'time' for the scatter plot. In Chart.js v3/v4 this requires a date adapter (e.g. chartjs-adapter-date-fns/luxon/moment) to be loaded; otherwise Chart.js throws at runtime (the built-in adapter stub is not implemented). Either include/register a date adapter in the dashboard HTML bundle, or switch the x-scale to a non-time scale (e.g. linear with numeric timestamps / pre-formatted year labels).

Fixed in commit 8602911 — switched scales.x.type from 'time' to 'linear' and added a ticks.callback that formats numeric timestamp values as 4-digit years. No Chart.js date adapter is required.

The custom CSV parsing in parseCsvLine toggles inQuotes on every " character and doesn’t handle escaped quotes ("") inside quoted fields. Several cia-data/*.csv files include fields with embedded quotes/commas (e.g. view_riksdagen_committee_decisions.csv), which will misalign columns and can make downstream lookups like row['winner'] unreliable. Use a proper CSV parser (e.g. d3-dsv’s csvParse or PapaParse) instead of this manual implementation, or extend the parser to correctly handle RFC4180 escaping.
There was a problem hiding this comment.
Fixed in commit d8ae736 — replaced the hand-rolled parseCsvLine/parseCsvFile functions with Papa.parse() from the papaparse package (already a project dependency). This correctly handles RFC 4180 escaping including "" within quoted fields and embedded commas/newlines.

There was a problem hiding this comment.
d3, Chart, and Papa are captured into top-level const bindings from globalThis at module evaluation time. If this script executes before the corresponding libraries are loaded (e.g. because of defer/ordering changes), these constants will remain undefined even after the globals appear, causing initialization to fail permanently. Prefer reading from globalThis at the point of use (or inside the init function) so late-loaded globals are picked up, or add a robust loader/order guarantee.
There was a problem hiding this comment.
Fixed in commit d8ae736 — removed the three top-level const d3/Chart/Papa bindings and moved them to the first lines inside the IIFE (right after 'use strict'). They now read from globalThis at call time rather than at script parse/evaluation time, so late-loaded libraries are always picked up.
