`?path=/Tests/test_folder` becomes `/files/Tests/test%20folder`. Directories only —
an open file stays `?view=`, because it is what is on top of you rather than where
you are, and that split is what keeps closing a pane from moving you.
── The landmine, found before building on it ──
`server.tsx` 404s any path ending .js/.css/.map/.png/.svg/.ico/.webmanifest/.woff2
that is not in `build/`, so it never reaches the SPA. A folder named `logo.png` is
unusual but legal, and it would have deep-linked to a 404 that reads as a broken
link rather than a rule.
Narrowed to SINGLE-SEGMENT paths, which is safe on evidence rather than by
loosening a rule: the bundler emits exactly three files, all at the root of
`build/`, so a real asset never has a second slash; and multi-segment assets
(`public/**`, `/plugins/<app>/icon.png`) are served by Bun's `routes` table before
this handler runs.
── Encoding is the part that breaks quietly ──
Per SEGMENT, never the whole path — encodeURIComponent would eat the separators.
14 tests over the round trip, because a filename may carry anything but `/` and
NUL. The ones that matter: `#` truncates a URL at the fragment if unescaped, a
literal `%` is mistaken for an escape, and malformed input must not throw
(decodeURIComponent('%zz') raises URIError, and that would take the screen down).
Parentheses stay readable — encodeURIComponent leaves them alone — so
`Kanban (copy 2)` survives as `Kanban%20(copy%202)`.
── The rest ──
- `/files` → `/files/*`. The bare route still matches with an empty splat, so every
existing link, the dock entry and DEFAULT_DOCK_PATHS keep working.
- Breadcrumbs take a `To` instead of a query string and are still real links.
- Old `?path=` URLs redirect once, in place, with `replace` so it is not a
back-button step. A bookmark from this morning still lands where it meant to.
- `setViewerParams` stopped copying `path` across, because there is nothing to
copy — the folder is the pathname and is untouched by a search-param write.
Checked and needing nothing: the page-title rule is `startsWith('/files')`, and the
dock uses react-router NavLink without `end`, so `/files/Tests` keeps the tile lit.
tsgo clean, frontend builds, 831 pass / 7 fail — +14 new, same 7.
