The file viewer converts word-processor documents to PDF server-side via
LibreOffice (skald_core::docx::DocxConverter), mirroring the LaTeX pipeline
but content-hash cached: the format is self-contained, so there is no
dependency graph and the file watcher needs no expansion. Container-only
documents are shuttled out and converted on the host. With no LibreOffice
installed the viewer says so and falls back to download-only. Downloads
still save the original document, not the preview PDF.
An eye next to the paperclip shares what the user has open with their next
message: the page, the folder being browsed, the file open in the viewer and
any highlighted passage (line numbers where a source view exists), plus which
entity a detail page is about. The bag is client-authored {label, value} pairs
in English — the backend only clamps (chars, never bytes), neutralizes the
harness tag and renders one <system-extra> block per message, deduped
consecutively so it appears exactly when the view changed. On by default,
per-device toggle, hover/tap to preview, a chip on every sent message;
docs/view-context.md for users, an updated harness.md clause for the model.
Until now file browsing existed only inside a project, and the two memory
stores were reachable only by the agent's tools. `#files` is the general
surface: home, both memory stores, the shared folders and projects the
caller belongs to, plus the read-only skills and docs trees.
The root is virtual, and that is the design. Anchoring at `~` is wrong:
the explorer reads host-side, while `shared/`, `projects/`, `skills/` and
`docs/` are bind mounts inside the container — a page rooted at the home
would show less than the user has with no way to reach the rest, and on
native Linux would show Docker's empty mountpoint stubs, a door that
appears to work and leads nowhere. So level 0 is a synthetic list from the
new `GET /api/files/roots`, serialized from the caller's `UserFs` plus the
two virtual memory roots. It sends `kind`, never a label: labels are copy
and get translated.
`GET /api/files/dir` now answers `{ path, can_write, entries }`, and a
memory path is classified before `resolve_view_path` (which refuses one)
and listed from `memory_docs`: one level derived from the flat key space
by the pure `memory_docs::immediate_children`, over a single query whose
unslashed prefix also spots an exact note as "not a directory". Memory is
read-only from the page — every writer routes through `resolve_view_path`,
and `shared-memory/*` is `@fs_write require` for the agent, so a button
that walks past that rule is a decision of its own.
The explorer moves out of projects into `shared/file-explorer.js`, taking
`root` + `rootLabel` and reading `can_write` from the listing rather than
from its host: writability changes per branch and comes from the same
`UserFs::can_write_to` the server rejects writes with, so the buttons
offered and the writes accepted cannot disagree. Deep-linking needed it
steerable without a two-way binding, hence `rel` in and
`explorer-navigate` out — the event fires only for a click, never for a
`rel` the host set, so echoing it back is a no-op.
The URL carries the agent path of the open folder in one parameter, the
same vocabulary the assistant uses, so a link is shareable and pasteable
into a conversation; which root it belongs to is derived, not stored.
docs/: a new files.md, plus two pages this made false — shared-folders.md
claimed in three places that a shared folder has no explorer, and
memory.md never said a user can now read their own notes.
