Conversation
…andover PE-9210 - DriveShareCubit guarded its work in nothing: a missing drive key threw StateError out of an un-awaited future started in the constructor, so the cubit never left DriveShareLoadInProgress and the dialog spun with no way out. DriveShareLoadFail existed, was rendered, and was emitted by nothing. - The dialog now shows that failure with a Retry action. - New CopyableShareArtifact, shared by both share dialogs, masks anything carrying key material behind a reveal toggle: the access key always, and the link only when the sharer embedded the key in it. Copy works while masked, since it copies the value rather than what the field displays. - First tests for the drive share path, including one that fails if the cubit hangs rather than failing. Two design system landmines are documented in comments and pinned by tests: ArDriveTextFieldNew latches obscureText in initState and never syncs it, and its built-in obfuscation toggle is unreachable on a disabled field.
…ve names PE-9210 S10 - a stalled gateway used to hang the share page forever. The data path has long been bounded (DataGatewayFallback: 10s request, 25s total, 1.5s hedge), but the GraphQL reads in front of it had nothing: GraphQLRetry retries a call that throws and sets no timeout, so a connection that errors was retried and one that simply hung was neither retried nor abandoned. Six reads now share an injectable 15s budget - the metadata fast path, the privacy lookup, the revision read, the license read, the freshness check and the version history. A timeout lands in SharedFileLoadFailure, which already offers Retry. S9 - the details drawer stated file id, transactions, owner and license, and no date at all; the only date on the page sat inside the version history, which is collapsed and not fetched until opened. It now leads with file type, date created and last updated, reusing the labels the owner-side panel already uses. S3 - a private drive's share link no longer carries its name. The name is as sensitive as the file names inside the drive, and nothing is lost by omitting it: the recipient's attach flow reads the real name off the drive's own record as soon as the key is in hand. The auto-attach gate was keyed on the name being present, so the name is now resolved before that gate - deliberately not inside submit(), which reads the name controller up front so a hand-typed name is the one the drive is attached under. Docs: SHARE_LINKS.md, an integration spec for third-party link producers, and SHARE_LINKS_PROPOSAL.md, the audit these changes come from - including where the audit overstated the caching and concurrency findings, checked against the code.
…eps its key PE-9210
S2 - a private drive link embedded the drive key unconditionally. It is now
keyless by default, with the key handed over as its own artifact and an opt-in
checkbox to embed it, carrying the reason: a drive key opens every file in the
drive for the life of the drive, and unlike a password it cannot be rotated.
Smaller than the audit assumed - the recipient side already existed, since
DriveAttachForm renders a masked, validated key field for a private drive.
S5 - folders can be shared. The drive key is now decoded once, before the route
shape is decided, and attached to whichever route matches; it used to be decoded
inside the drive branch and returned from there, so a *valid* key made the folder
segments unreachable and /drives/{id}/folders/{fid}?driveKey= silently resolved
to the drive root. Only a damaged key ever reached the folder route, which is
exactly backwards. Share actions added to the details panel and the folder menu.
Also fixes a regression from the previous commit: restoreRouteInformation wrote
the drive key back only alongside a name, and private links no longer carry one,
so a keyed link lost its key on the first route restore. The location is now
rebuilt from whichever parts are present.
Known limit, documented rather than papered over: a folder link opened by someone
who does not yet have the drive attached lands at the drive root, because the
folder id is cleared while the drive is attached and re-selected. Not a
regression - the folder was previously dropped at the parser.

Guard the new driveNameLoader call against failures.
This code runs inside the Future.microtask started at line 70. initializeForm is called from the constructor at line 55 and its future is never awaited. driveNameLoader uses try/finally with no catch, and _arweave.getLatestDriveEntityWithId performs network work. A network or decode failure therefore escapes as an unhandled asynchronous error, and the cubit emits no failure state.
driveNameLoader also returns false when the key is invalid or the entity is missing. In that case the name stays empty, the auto-submit at line 109 is skipped, and the user gets no feedback.
Wrap the call and emit a failure state when name resolution fails.

Reset _isRevealed when the artifact changes.
_isRevealed lives on the state and survives widget updates. The dialogs reuse one CopyableShareArtifact element for the link across cubit reloads, so the reveal decision carries over to a different value.
Sequence: the sharer checks "include key in link", reveals the masked link, unchecks the box, then checks it again. isSecret returns to true, but _isRevealed is still true. The new key-bearing link renders in clear text without a new deliberate reveal. That contradicts the property documented at lines 11-19.
Reset the flag when text or isSecret changes.

The one that mattered: the share dialogs filled their fields from a bloc listener, and a listener does not fire for the state a bloc is already in. The public drive path builds its link synchronously, so the dialog reached the success state before it could listen and the link field rendered empty. CopyableShareArtifact now owns its controller and takes the value directly, which removes the whole class of bug from both dialogs. - Reveal state resets when the value underneath it changes, so ticking "include the key in the link" does not inherit the previous reveal. - DriveShareCubit captures the key-embedding flag per load and guards its emit with a generation counter. Two loads racing after a fast double-toggle could otherwise emit a link built with the key in it while labelling it keyless - which the dialog would then render unmasked. - DriveShareLoadSuccess redacts the drive key from toString, since equatable stringifies props in debug builds. Same treatment FileShareLoadSuccess gets. - Folder sharing was added to EntityActionsMenu, but the explorer renders folder rows with DriveExplorerItemTileTrailing, so the action was invisible where users would look for it. Added there too. - The drive name lookup during attach is guarded; it runs inside a microtask nobody awaits, so a network failure escaped as an unhandled async error. - Bounded the two reads in submit(), the unlock path, which could hang the locked page after a key was pasted. - The details drawer test now uses distinct created and modified dates, so each row is pinned to its own field. Not taken: routing every shared file read through a cancellable request. True that Future.timeout does not cancel its source, but the bug being fixed was a page that hung forever, and it no longer does. Cancellation belongs at the GraphQL client, which sync shares and which PE-9205 has just tuned - too wide a blast radius for this change.

Thanks — several of these were real, including one I should have caught myself. The empty public-drive link field was the important one. Both dialogs filled their fields from a bloc listener, and a listener does not fire for the state a bloc is already in. The public drive path builds its link synchronously — I had actually documented that fact in a test comment while writing the cubit tests — so the dialog reached success before it could listen, and the field rendered blank. Fixed at the root: Folder sharing being invisible in the explorer was the other real miss. I could not find where folder rows built their menus when I looked, and settled for Also taken: the per-load flag capture and generation guard in One declined: routing every shared-file read through a cancellable request. The observation is correct — Local: 1375 passed, 4 skipped, 0 failed. |

The finders searched the whole tree, so created and modified could have been swapped between rows and the test would still have passed. Each value is now found under its own label's row, and the expected strings are literal rather than produced by formatDateToUtcString - deriving them from the formatter under test let a format change rewrite the production output and the expectation together.

1970 in the details drawer. A v2 link carries no timestamps, so the revision
the page paints from holds an epoch placeholder until the metadata resolves -
a contract the cubit states explicitly ("rendered as unknown, never as 1970").
The new date rows ignored it and put 1970-01-01 in front of the recipient as
though it were the upload date. They are now gated on detailsAreResolved, with
a test that pumps the unresolved state.
Copy that no longer matched the product. "Anyone can access this private drive
using the link above" was written when the key was always embedded; for the
keyless default it is simply false, and it is the sharer's only cue that they
still have to send the key. A keyless private link now says so instead.
The dialog never showed what was being shared. ArDriveStandardModalNew renders
`description` only when `content` is null, and this dialog always has content,
so the drive name passed to it was never on screen - and a folder share would
have confirmed the drive's name rather than the folder's anyway. The name is
now rendered in the content, and folders carry their own.
Ghost folders offered a share action. Their metadata was never found, so a link
naming one points the recipient at nothing.
Also adds the drive share dialog's first widget tests. Its absence is why the
empty public-drive link field reached review at all, and why the modal's dead
`description` went unnoticed - both were found by writing them.
…h PE-9210 Toggling "include the key in the link" re-ran the whole load: it re-announced DriveShareLoadInProgress, which the dialog renders as a centred spinner, so the dialog blanked and the checkbox the sharer had just clicked left the screen and came back. It also went back to the database for a drive key that cannot have changed. The key is now resolved once and the toggle rebuilds the link with no loading state, which is what the file share dialog has always done. The sharer's one network read - the cipher tags that fill `c`/`iv` - is now bounded. GraphQLRetry retries a call that throws but sets no timeout, so a gateway that hung left the dialog saying "finishing your link" for as long as it stayed open, telling the sharer to wait for something already done. The link is complete and copyable without those two fields; they only save the recipient a lookup.

…9210 The two dropdown menus refuse to share a ghost folder - its metadata was never found, so a link naming it points the recipient at nothing - but the details panel's share icon, the third entry point, did not. Now all three agree. Hoisting `item` to a local for the promotion this needs also made four existing casts in the same method redundant; they are gone.

…PE-9210 A folder link only ever opened the folder for someone who already had the drive. Everyone else - which is every stranger a public folder link is sent to - went through the attach flow, which ends by clearing driveId so the prompt cannot re-fire; the drive is then selected fresh, the folder reads as belonging to a different drive, and it is dropped. A folder link was a drive link with extra characters. The delegate now holds the drive a folder link named until that drive is the selected one, and releases it immediately after, so ordinary navigation still discards a folder as it always has. The attach form no longer goes silent on a link whose key is wrong. Auto-attach was gated on having a name as well as a key, so a link that could not resolve one just sat there with the key filled in and nothing said why. It is gated on the key alone now, and submit() surfaces the real outcome through the states it already emits - DriveAttachInvalidDriveKey, DriveAttachDriveNotFound. What made that gate necessary was submit() freezing the name before the loaders that resolve it, so an empty one would have been persisted. It now reads the typed name up front and falls back to the resolved one when nothing was typed: a hand-typed name still wins, an absent one is no longer mistaken for a choice. That also drops the extra lookup the previous commit added, since submit() resolves the name on its way through anyway.
…d PE-9210 The reconciliation lived in an inline BlocListener closure, which is why it shipped untested while everything else here has coverage. It is a named method on the delegate now, called by that listener, so it can be exercised without standing up the whole app shell. Seven tests: a folder link opens its folder both for someone who already had the drive and for someone the attach flow ran for; the pending folder is released once honored, so returning to that drive later lands at its root; it never follows the user to a different drive; a drive link holds nothing back; and ordinary navigation discards or keeps the folder exactly as before. Verified to bite - reverting the fix fails the first of them. The other six pass either way by design: they fence the change in rather than prove it.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Clear the pending marker after an unrelated drive selection.
If the user selects a different drive, Line 77 clears driveFolderId but _pendingFolderDriveId remains set. After Line 270 stores the new drive's folder, a later selection of the originally linked drive matches the stale marker and preserves that wrong folder ID. DriveDetailCubit can then receive a folder from another drive as initialFolderId.
Clear _pendingFolderDriveId when selectedDriveChanged is true. Add a regression test that selects another drive, sets its folder, and then returns to the original linked drive.

Version history stopped loading, and that was mine. The resilience pass put the 15s first-paint budget on `loadActivity`'s read - the one query on the page that walks the file's entire revision history, is asked for only when the recipient opens the drawer, and blocks nothing while it runs. A file with real history, or a slow gateway, then reported "version history unavailable" where it used to simply take a while. It has its own two minute budget now. The share drive modal's layout: - The reveal control only exists on a secret row, so it stole width from the key field and not the link field: two boxes of visibly different widths, stacked. Its slot is now reserved on every row, and the field widths are asserted equal. - The access notice was `paragraphLarge` - the largest text in a dialog whose subject is the two fields above it. It is `paragraphNormal`, muted, now. - Helper lines use the same treatment as the file share dialog's rather than an ad hoc padding, so the two dialogs read as one design. - The reveal button no longer carries Material's default 48px padding, which was what left it floating between the field and the copy action.
…ed PE-9210 `c` and `iv` are in the link schema so that a private download does not have to ask the network what its own bytes are encrypted with. Nothing ever read them: `SharedFileLinkPayload.hasCipherDetails` was defined and referenced nowhere, and every private download issued a `getTransactionDetails` for tags the link had already delivered. The sharer even pays a lookup to populate those fields, so they were pure cost - longer links, an extra call on the way out, nothing saved on the way in. On a rate-limited connection that is not waste but a call that can fail outright. The page now hands the link's cipher to the download, and the download uses what it is given. Guarded on the link naming a *bundled* data item and the *current* target: `verifyDownload` turns on the arweave client's chunk check for L1 transactions and is decided by a tag on that same lookup, so skipping it for something that might be L1 would drop a check silently. A bundled item is not an L1 transaction, so there is nothing to drop. A recipient who has moved the page to a newer revision gets the lookup, since the link never described those bytes. Attach drive says what is happening. Entering an id that resolves to a private drive showed nothing but a key field appearing; it now says the drive was found and what is still needed. The lookup progress line was hardcoded English and is localized.
… PE-9210 The pending marker preserved whatever folder was in view when its drive was finally selected, rather than restoring the one the link named. Between the link opening and that drive arriving the recipient may have been somewhere else entirely - so opening a folder link for drive A, wandering into a folder of drive B, and then landing on A showed B's folder under A's name. The folder is now held with the drive it belongs to and restored by id, which cannot name a folder from anywhere else. Verified to bite: reverting the restore fails the new test.

The folder-marker finding was right, and my tests had missed it. Fixed in The marker preserved whatever folder happened to be in view when its drive was finally selected, instead of restoring the one the link named. Open a folder link for drive A, wander into a folder of drive B before A is selected, then land on A — and you got B's folder under A's name. The folder is now held with the drive it belongs to and restored by id, which cannot name a folder from anywhere else. Verified the new test bites by reverting the restore. I took that over the suggested "clear the marker on an unrelated selection". Clearing also fixes the wrong-drive symptom, but it throws away the link's intent for anyone who does not land on the drive immediately — and the attach flow is precisely a navigate-away-and-return. Restoring by id is safe in both cases: it can never surface another drive's folder, and the recipient still gets the folder they were sent. On the rest of the summary: Local: 1394 passed, 4 skipped, 0 failed. |

An end-to-end pass over sharing — from pressing Share to the recipient having bytes. The file path was rebuilt by PE-9200 and PE-9202 and is in good shape; this fixes what those left behind, most of it on the drive and folder side.
What was wrong
The drive share dialog could hang forever.
DriveShareCubit.loadDriveShareDetails()threwStateError('Drive key not found')out of anasyncmethod called from the constructor and never awaited, with notry/catchin the class. The throw became an unhandled asynchronous error, the cubit never leftDriveShareLoadInProgress, and the dialog spun with no way out.DriveShareLoadFailexisted, was rendered, and was emitted by nothing — dead code covering a state that could not be reached.Keys were masked when typed in and shown in the clear when handed out. The recipient entering an access key got an obscured field; the sharer handing one over got it rendered in full, as did a drive link with the key inside it. That is backwards — typing a key is a private act, but handing one over is the moment a screen is most likely to be shared, recorded or screenshotted.
A stalled gateway hung the shared file page indefinitely. The data path has long been bounded (
DataGatewayFallback: 10s request, 25s total, 1.5s hedge). The GraphQL reads in front of it had nothing:GraphQLRetryretries a call that throws but sets no timeout, so a connection that errored was retried and one that simply hung was neither retried nor abandoned.The share page showed no dates. The details drawer listed ids, owner and license and no timestamp at all; the only date on the page sat inside the version history, which is collapsed and not fetched until opened. When a file was uploaded is the strongest signal a recipient has about a link from a stranger.
Private drive links leaked the drive name, always embedded the drive key with no opt-in, and folders could not be shared at all.
A folder link could not carry a drive key. The key was decoded inside the drive branch and returned from there, so a valid key made the
folderssegments unreachable and/drives/{id}/folders/{fid}?driveKey=…silently resolved to the drive root. Only a damaged key ever reached the folder route — exactly backwards.What changed
DriveShareLoadFailwith a Retry action, and the drive share path gets its first tests.CopyableShareArtifact, shared by both dialogs, masks anything carrying key material behind a reveal toggle. Copy works while masked, because it copies the value rather than what the field displays.SharedFileLoadFailure, which already offers Retry.Things worth a reviewer's attention
Two design-system landmines, both documented in comments and pinned by tests in
test/components/copyable_share_artifact_test.dart:ArDriveTextFieldNewlatchesobscureTextininitStateand never syncs it, so toggling the property on a mounted field does nothing (the field is keyed to force a remount, the same trick the file dialog already uses on its checkbox); and its built-inshowObfuscationTogglerenders inside the decoration of a disabled field, which swallows the tap, so the mask could never be lifted. The reveal control is ours for that reason.The attach flow's auto-submit gate. Dropping the name from private links would have silently stopped keyed links from attaching themselves, since the gate required a non-empty name. The name is now resolved before that gate — deliberately not inside
submit(), which reads the name controller up front so that a name the user typed by hand is the one the drive is attached under. Moving that read later would have discarded it.A regression caught mid-flight.
restoreRouteInformationwrote the drive key back to the address bar only alongside a name. With the name gone, a keyed link lost its key on the first route restore and a refresh would ask the recipient for a key their link already had. The location is now rebuilt from whichever parts are present, and there is a test for it.Known limit, left standing deliberately
A folder link opened by someone who does not already have the drive attached lands them at the drive root, not the folder: the folder id is cleared while the drive is attached and re-selected. Preserving it means reaching into the drive-selection logic that all normal navigation shares, which is a poor trade against the benefit — and it is not a regression, since the folder was previously dropped at the parser before it ever got that far. Recipients who already have the drive, the common case for folder sharing, land on the folder.
