Summary

Fixes #412.

Inspect mode climbs inline text to the nearest editable container. Agenda (and similar list wrappers) put a loc-tagged <span> inside an untagged <li>. The climb lands on the <li>, and findSlideSource(..., { hostOnly: true }) then has no slide loc to read, so the panel never opens.

This keeps a loc-tagged inline as the pick target instead of promoting it. Untagged inlines still climb to their paragraph. Tagged wrapper hosts are not inline tags, so this does not undo the shared-component case from #327.

pickInspectorTarget now lives in pick-target.ts so the unit tests can cover the climb without the overlay.

Evidence

Unit tests on a fake DOM (node environment, no happy-dom):

pnpm exec vitest run packages/core/src/app/lib/inspector/pick-target.test.ts
Test Files  1 passed (1)
Tests  6 passed (6)

Reverting the tagged-inline keep makes keeps a loc-tagged span inside an untagged list wrapper fail.

Biome 2.5.7 check on the touched files is clean.

What was not tested

Playwright e2e (agenda-select fixture, assert <span> + Element text What changed?) is in the PR and will run in CI. I did not run it locally: this box is under load and the worktree has no real pnpm install (only a temporary junction for vitest).

I also did not click through a live demo deck with the real Agenda primitive.

AI assistance

This change was prepared with AI assistance (Cursor/Grok). I reviewed the diff, ran the unit tests above, and kept the pick change scoped to tagged inlines.

Test plan

  • Unit: tagged span in untagged <li> stays the span
  • Unit: untagged span still climbs to <p>
  • Unit: tagged span is not promoted to a tagged wrapper host
  • CI: Playwright inspector test on agenda-select
  • Maintainer: Inspect click on Agenda row text in a real deck

Summary by CodeRabbit

  • Bug Fixes

    • Improved inspector selection for inline text nested within Agenda-style lists.
    • Tagged inline text remains selectable and is correctly identified in the inspector.
    • Inspector details now display the selected element and its text more reliably.
  • Tests

    • Added coverage for inline-text selection and inspector behavior.
    • Added an Agenda Select example to validate the experience across supported views.

Review Change Stack

Walkthrough

The inspector now keeps loc-tagged inline elements as targets inside Agenda list wrappers. A shared target-selection helper, unit tests, an Agenda fixture slide, and browser test coverage were added.

Changes

Agenda inspector selection

Layer / File(s) Summary
Inspector target selection and unit coverage
packages/core/src/app/lib/inspector/pick-target.ts, packages/core/src/app/lib/inspector/pick-target.test.ts, packages/core/src/app/components/inspector/inspect-overlay.tsx
Target selection now preserves tagged inline elements, identifies editable text containers, and falls back to the original element. Unit tests cover tagged and untagged inline elements and wrapper hosts.
Agenda fixture and end-to-end validation
packages/core/e2e/fixture/components/agenda.tsx, packages/core/e2e/fixture/slides/agenda-select/index.tsx, packages/core/e2e/fixture/tsconfig.json, packages/core/e2e/tests/*.spec.ts, .changeset/agenda-inspector-pick.md
A new Agenda fixture and slide exercise inline text selection. Browser tests validate inspector selection and update fixture-count assertions. A patch changeset records the package release.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to f4dec

The PR keeps tagged Agenda text selectable in Inspect mode without changing system boundaries or runtime configuration. The remaining bounded risk is that the browser test does not directly verify the resolved source location, so merge is reasonable with explicit owner follow-up to strengthen that assertion.

A rabbit clicks where tagged spans glow
The inspector finds the text below
Through list-row paths the target stays
Tests hop along in leafy ways
A fresh deck joins the cards today

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add an assertion for the source location.

This test verifies panel visibility, <span> identification, and editable text. It does not verify the source location required by the Agenda inspect flow. Add an assertion for the inspector’s source-location field. Without it, the test can pass while source resolution still fails.
