From 79ea2f68241215da5c032c6860d158bb3786a2c1 Mon Sep 17 00:00:00 2001 From: robbond Date: Sat, 1 Aug 2026 15:39:30 +0100 Subject: [PATCH] feat: add v0.3 normalised comparison reasoning Add explicit reasoning guidance for normalising counts by exposure/denominator, distinguishing total count from rate, and avoiding correlation-as-causation errors. Changes: - prompts/reconstruct-v0.3.md: new prompt with normalisation discipline - lib/reconstruction/prompt.js: v0.3 loader + env var override support - lib/analysis.js: defer DEFAULT_PROMPT_VERSION to prompt module (defaults to v0.3) - PROMPT_VERSIONS extended to [v0.1, v0.2, v0.3] - tests/v03-reasoning.test.js: 34 focused tests covering prompt loading, schema validation, guidance completeness, and target scenario fixture - playwright.config.js + tests/smoke.test.js: minimal UI smoke test for browser rendering - package.json: add @playwright/test as devDependency Default switches to v0.3; v0.2 selectable via promptVersion or RECONSTRUCTION_PROMPT_VERSION env var. --- lib/analysis.js | 3 +- lib/reconstruction/prompt.js | 32 +- package-lock.json | 68 +++- package.json | 1 + playwright.config.js | 5 + prompts/reconstruct-v0.3.md | 160 ++++++++++ tests/smoke.test.js | 55 ++++ tests/v03-reasoning.test.js | 598 +++++++++++++++++++++++++++++++++++ 8 files changed, 914 insertions(+), 8 deletions(-) create mode 100644 playwright.config.js create mode 100644 prompts/reconstruct-v0.3.md create mode 100644 tests/smoke.test.js create mode 100644 tests/v03-reasoning.test.js diff --git a/lib/analysis.js b/lib/analysis.js index 8741cf1..d214dca 100644 --- a/lib/analysis.js +++ b/lib/analysis.js @@ -5,14 +5,13 @@ import { getConfig } from "../lib/config.js"; import { getProvider } from "../lib/llm/provider.js"; -import { buildPrompt, PROMPT_VERSIONS } from "../lib/reconstruction/prompt.js"; +import { buildPrompt, PROMPT_VERSIONS, DEFAULT_PROMPT_VERSION } from "../lib/reconstruction/prompt.js"; import { reconstructionV2Schema, reconstructionSchema as reconstructionV1Schema, } from "../lib/reconstruction/schema.js"; const MAX_SCENARIO_LENGTH = 10000; -const DEFAULT_PROMPT_VERSION = "v0.2"; /** * Analyse a scenario string through the full pipeline. diff --git a/lib/reconstruction/prompt.js b/lib/reconstruction/prompt.js index 66edeab..5de4609 100644 --- a/lib/reconstruction/prompt.js +++ b/lib/reconstruction/prompt.js @@ -7,7 +7,14 @@ const __dirname = dirname(__filename); const PROMPTS_DIR = join(__dirname, "../../prompts"); /** Available prompt versions */ -export const PROMPT_VERSIONS = ["v0.1", "v0.2"]; +export const PROMPT_VERSIONS = ["v0.1", "v0.2", "v0.3"]; + +/** Default prompt version (override via RECONSTRUCTION_PROMPT_VERSION env var) */ +const defaultVersionFromEnv = process.env.RECONSTRUCTION_PROMPT_VERSION; +export const DEFAULT_PROMPT_VERSION = + defaultVersionFromEnv && PROMPT_VERSIONS.includes(defaultVersionFromEnv) + ?
