- docs/plans/2026-09-11-file-icons-and-tab-glyphs.md: the design record —
what the two stacked PRs did, the measured upstream facts that made their
colored implementation redundant (rc.2's `FileTypeIcon`/`CodeFileIcon` with
the host's own palette, the classifier never returning a folder, the native
tab definition having no icon field while its title slot IS the chip), the
three merge conflicts and how each was resolved, what was deleted, the
catch-all semantics change, and the verification evidence.
- docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md: cross-link it from the
change table.
- docs/external-plugin-guide.md: the file-icon fallback chain now ends at the
host's artwork, with the catch-all caveat spelled out; §12 loses its "one
exemption" paragraph entirely — the plugin draws no color of its own any
more (file icons are host pixels, tab glyphs ride tokens).
- AGENTS.md §5: replaces the icon-theme exemption with the two new rules
(file-icon chain + catch-all hazard, and where the colored tab glyphs live
plus the fact that the native chip glyph is drawn by the plugin inside the
host's title slot).
- README.md / README_EN.md: the v0.19.1 entry gains the icon section
(#611 / #531 / #594) with the dataset deletion and the new public API.
