Fix History Tool URL — use github-pages tpen-line-history#519
Merged
Conversation
The Tools.defaultTools History Tool URL pointed at https://app.t-pen.org/components/line-history/index.js, which 404s — the local component was deleted from tpen3-interfaces in 1c25cbe. The github-hosted tpen-line-history custom element is the working artifact and is published at: https://centerfordigitalhumanities.github.io/tpen-line-history/tpen-line-history.js tagName stays tpen-line-history so it continues to load as a custom element (not an iframe).

Summary
Fix the broken Line History tool URL in
Tools.defaultTools. The previous URLhttps://app.t-pen.org/components/line-history/index.js404s — that file was deleted fromtpen3-interfacesin commit1c25cbe(Feb 2026). The replacement points at the github-pages build of the dedicatedtpen-line-historyrepo, which still publishes a workingtpen-line-historycustom element.This change rides along with the broader TPEN ↔ tool messaging contract cleanup (see CenterForDigitalHumanities/TPEN-interfaces#564 for the full story) but is independent of the protocol changes and could ship on its own.

Test plan
Developer-validated locally on 2026-05-08:
npm run allTestspasses — 187/187 ✅ (113 integration tests skipped, as expected without a live test stack)./transcribeagainst a project with the History tool, confirmed the custom element loads in the pane (no 404 in console). Live-line tracking on the local stack is gated on Hardcoded prod TPEN module URL prevents local-stack and dev-stack testing tpen-line-history#5 (the tool hardcodeshttps://app.t-pen.org/api/TPEN.js, so its TPEN module instance is siloed from the local interfaces' module instance — works on prod where the URLs dedupe).Companion follow-up (deferred, does not block this cut)
