feat: render file version history in the details dialog - #1866
Conversation
The details dialog reads a file's prior versions with the engine's fileVersions call when it opens, and reads them again after a restore or a delete. Each entry offers a download, a restore, and a delete, named by its content root CID. The two writes confirm first, and a command in flight holds the dialog open until the engine answers.

when the fileVersions read fails. Then handle loading and empty states
separately before rendering the main view, preserving the existing behavior for

Render the version section when the read fails, so the alert is not suppressed by the empty entry list. Hold the confirmation for the whole write, which spans the engine call and its re-read. Clear the entries when the dialog is given another node.

- Line 69: Update DetailsDialog’s PendingWrite flow to store the originating
node identity, clear or reject pending confirmation when the displayed node
changes, and capture the active-node generation when a write begins. In the
confirm/version-write path, use the stored node context rather than the current

still matches the active generation.

The details dialog takes its node as a prop, so the parent can swap it in place. An unanswered confirmation stayed open across that swap and sent the previous node's contentCid against the new node. An accepted write also re-read the list for the node it named, which then landed on the node the dialog had moved to. The dialog now retires a pending confirmation in the render that changes the node, and ignores the outcome of a write it has left the node of. The hook re-reads after a write only while that write's node is still the one on screen.
Review disposition for the CodeRabbit review of 2026-09-16T20:09:40ZHead after the fix: ee7bcd6. Inline thread, 1 item
The dialog holds a ref of the node it shows. A node change retires the pending confirmation in that same render and makes the dialog ignore the outcome of a write for the node it has left. Review body sectionsThe review body of 2026-09-16T20:09:40Z carried no "Outside diff range comments" section and no "Nitpick comments" section. It reported one actionable comment and nothing else, so there is no further item to disposition. Checks after the fix

If the dialog changes from node A to B and back to A before the first A write resolves,
shown.current === targetpasses again. If the user opens a new confirmation for A, the old accepted write clears that new confirmation and setsconfirmingtofalse.Track a display epoch or write token. Require it to match before updating confirmation state.

A node swap away and back left the node check passing for a write from the earlier display, so an accepted result cleared a later confirmation. The confirmed write itself is now the token the result must match.
Review disposition — CodeRabbit review of 2026-09-16T22:37:48ZThis review reported one item under "Duplicate comments", with no inline thread. Item (Major) — Disposition: accepted and fixed. Mechanism. The result guard compared the node only. The dialog shows node A, the member confirms a write, and the write stays in flight. The dialog then shows node B and is shown node A again. Each display starts its own read of the version list, and the read of the second A display clears the busy state, so the entry controls become live again while the write is still open. The member opens a new confirmation for A. The first write then lands. Fix. The dialog now holds the confirmed write itself as the token of its display. A node swap sets the token back to Test. Commit: f08b6c1. All required checks pass on that head. |

What this does
The details dialog now shows a file's prior versions and acts on one.
useFileVersionsreadsfacade.fileVersions(node)when the dialog opens, and reads it again after a restore or a delete, because either write rewrites the list. Prior versions are not a snapshot field.VersionHistoryrenders one row per entry: the clamped content root CID, the modified date, and the size, all fromVersionEntryDescriptor. The client computes no version metadata of its own. A file with no prior version renders no history section.contentCid.ConfirmDangerDialog. A refusal keeps the confirmation up and reports the engine's own message.fileVersionsread does not hold it, so a slow read cannot trap the member. An unanswered confirmation also holds the dialog, so one Escape cannot dismiss both dialogs.version-download-guard.tsis not ported. It gated on a vault key held in the client, and v2 web holds no key. The engine refusal is the equivalent, and it surfaces as a normal command error.Supporting changes:
lib/saveBlob.tsholds the buffered save path thatuseFileDownloadhad inline, so the version download and the file download share one implementation.utils/format.tsgainsclampId, whichshortAccountIdand the version CID label both call.packages/clientexportsVersionEntryDescriptorfrom its barrel; the type was defined but not exported.Tests
apps/web/src/components/file-browser/details/versions.test.tsx, 10 cases, each one red against the unfixed code:fileVersions, for the node on screen;contentCid;details.test.tsxnow mounts inside an engine provider, because the panel reads versions on open.Verification run in the worktree:
pnpm -r typecheck,pnpm lint,pnpm lint:tracker-refs,pnpm -F @cipherbox/web test(745 pass),pnpm -F @cipherbox/client test(723 pass).Manual verification
Puppeteer was not driven for this change: the dialog needs a logged-in engine session and a file with a write history, which the browser MCP cannot reach on its own. Manual steps:
details. Theprior versionssection lists two entries, newest first, without the current version.dlon the older entry. The browser saves the file under the file's name.restoreon the older entry, then confirm. The list re-reads and the restored version leaves it.rmon an entry, then confirm. The entry leaves the list.Body checks / follow-ups filed
