Split unit N2 of #1546 (F1a — durable per-view viewStates pipeline)
Second unit of the split plan recorded in the tracking issue (fork issue 41). Depends on N1 (identity/claim); the buffer/mutation/write-path content is not included.
Scope (contract point)
Serialized persistedViewStateWriteQueue, fresh-read merge on save, 50-entry prune, corrupt-value guard.
Rekey on registration, clear on reset/delete, and export/import sanitization for viewStates (ContextProxy omit, importExport skip).
Typed ProviderSettingsNotFoundError handling used by the identity/adoption path.
Split unit N2 of Zoo-Code-Org#1546: viewStates read/write queue, claim rekey, prune, clear, load/save and export/import sanitization on top of N1 identity. Buffer/mutation/history content remains for N3.

Current step: Required CI passed. Waiting for automated review of the latest commit.
If automated review does not start, a maintainer must restart it.

Mode and provider-profile selections are now saved separately for each webview and restored when it is reopened.
Bug Fixes
Saving a provider profile now refreshes the selection in views pinned to that profile.
Failed settings saves and resets no longer restore outdated cached values.
Deleting a configuration that doesn’t exist now reports a distinct not-found error.
Settings
Per-view selections are excluded from settings exports and are ignored when importing settings.
The PR adds claimed per-view persistence and restoration for mode and provider-profile selections. It excludes viewStates from settings import and export, updates global-state cache handling for failed writes, and adds a distinct error type for deleting a missing provider configuration.
Changes: Per-view State
Layer / File(s)
Summary
View-state and message contracts packages/types/src/global-settings.ts, packages/types/src/vscode-extension-host.ts, packages/types/src/__tests__/*
The global settings schema adds viewStates records and their fields. Extension messages add view-state IDs and claims. Tests cover schema validation and global-state key registration.
Global-state writes and settings transfers src/core/config/ContextProxy.ts, src/core/config/importExport.ts, src/core/config/__tests__/*
ContextProxy avoids restoring stale cached values after failed writes or resets. Settings export omits viewStates, and import skips it. Tests cover cache behavior and transfer handling.
Claimed view-state registration and persistence src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts
ClineProvider validates IDs and claims, merges and serializes persisted entries, re-keys temporary entries, and prunes entries to the newest 50. Tests cover registration, ownership, persistence, and concurrent writes.
Selection restoration and profile updates src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts
ClineProvider restores saved selections and tracks view-local updates. Profile activation and saving update buffered API settings under the described conditions. Tests cover loads, local updates, and write failures.
Deleting a missing configuration throws ProviderSettingsNotFoundError. Other deletion errors remain wrapped, and tests distinguish a missing configuration from a storage error containing “not found.”
The persistence groundwork is mergeable with a bounded malformed-data follow-up. Reload integration remains deferred; existing cache and profile-refresh limitations are not worsened by this change.

Full details: Security Boundaries
Explanation
No concrete security-boundary failure is introduced. ClineProvider persists only mode, profile name, timestamps, and host-minted claim tokens. It never accepts a claim token from view-state values. setViewStateId bounds and normalizes IDs, rejects __proto__, checks live ownership, and requires an exact stored claim before loading an existing entry. ContextProxy.export() and importExport omit viewStates, preventing claim or profile-state transfer. The changed code does not persist API keys or execute profile names as commands, and no new webview message dispatch bypasses these checks.
Full details: Persistence Integrity
Explanation
FAIL — the changed durable view-state path can lose access to stored claims and does not propagate restored selections. savePersistedViewState() writes viewStates, then postViewStateClaimToWebview() uses void this.postMessageToWebview(...) (ClineProvider.ts:663-716). postMessageToWebview() catches and drops delivery failures (:1988-1992). If the webview closes or delivery rejects after the write, the stored claim is inaccessible, while setViewStateId() later requires that claim (:856-863). The launch path still sends only webviewDidLaunch (webviewMessageHandler.ts:594-600; ExtensionStateContext.tsx:600-609), and the frontend has no viewStateClaim handler. Separately, loadViewState() stores restored mode and profile data only in viewLocalState (ClineProvider.ts:913-972), while getState() reads shared ContextProxy values and getStateToPostToWebview() consumes that result (:3608-3729, :3363-3491). A persisted per-view mode or profile therefore does not reach the state consumer. Profile activation also calls setValue() without updating the view-state buffer, and its added helper receives only apiConfiguration (:2550-2556, :3862-3864, :3884-3900), so the activated profile name is not durably saved per view.
Resolution
Make claim delivery awaitable and error-propagating. Add retry or recovery behavior so a successful viewStates write cannot leave an inaccessible claim. Send the stable view ID and presented claim with webviewDidLaunch, await setViewStateId() before posting state, and add frontend handling for viewStateClaim that stores and echoes the host claim. Merge viewLocalState over shared values in getState() or getStateToPostToWebview(), including clears. Route profile activation through the same durable mutation helper and persist currentApiConfigName together with the local buffer update.
Full details: Regression Evidence
Explanation
The standing failure remains unresolved. ClineProvider.setViewStateId now has a non-string rejection branch at lines 783-788 and an oversized normalized-ID rejection branch at lines 806-810. The added ClineProvider.spec.ts tests cover "__proto__" and other string IDs, but no test passes a non-string value or an ID longer than 64 characters. These changed negative branches lack focused regression coverage.
Resolution
Add focused ClineProvider.spec.ts tests for a non-string viewStateId and for a normalized ID longer than 64 characters. Assert that each call keeps the provider on its previous ID and does not load or mutate persisted state or deliver a claim.
Full details: Lifecycle Resource Cleanup
Explanation
The prior lifecycle leak remains unresolved. The changed constructor adds this to ClineProvider.activeInstances at src/core/webview/ClineProvider.ts:424 before getWorkspacePath() at line 425. getWorkspacePath() calls vscode.workspace.getWorkspaceFolder() without a catch at src/utils/path.ts:164. If that API throws during workspace or editor teardown, construction aborts before the caller can dispose the provider. The instance remains in activeInstances; normal cleanup removes it only at ClineProvider.ts:1382. The base revision added the instance after getWorkspacePath() and therefore did not have this path.
Resolution
Move ClineProvider.activeInstances.add(this) after synchronous initialization that can throw, including getWorkspacePath(), or remove the instance from activeInstances when constructor initialization fails.

N2 spec now includes the N1 identity tests plus the persistence/load/prune/rekey/export-import coverage; the setValues buffer test moves to the buffer unit.
getPersistedViewStates copies a null entry into the map. prunePersistedViewStates then reads .updatedAt on that entry during sorting. The queued write rejects before setValue runs, so the null entry stays in storage and every later write fails the same way. Filter out entries that are not objects in getPersistedViewStates. The next successful write then removes the bad entry.

Rebuild a task that runs under the saved profile, even when this view pins a different profile.
The rebuild at src/core/webview/ClineProvider.ts:2633-2641 runs only when this.pinnedProfileName === name. A task whose taskApiConfigName is name but whose view pins another profile keeps its old API handler after a non-activating save. The inner taskApiConfigName === name check already prevents switching other tasks, so the outer pin check blocks a rebuild that should happen. This predates the PR. The non-activating branch never rebuilt the task before, and this change only adds the pinned-view rebuild.
🐛 Suggested fix

await this._saveViewLocalStateFromMutation({ apiConfiguration: providerSettings })

Track a per-key write generation so a rejected write only rolls the cache back while it is still the newest write for that key; also stop tracking the generated .husky/_ hook files.

Follow-up Comments
Restore the committed value when overlapping rejected writes fail.
380-383: Minor · Stability & Availability · Quick win
Restore the committed value when overlapping rejected writes fail.
updateGlobalState captures previousCachedValue at the start of each write. If two writes to the same key overlap and both storage updates reject, the cache ends at the value of the first write, while storage keeps the original value. The generation check does not prevent this. Write B captures A as its previous value, and B's rejection restores A. A's rejection is skipped because B has a newer generation.
Suggested direction
Restore from a value that reflects committed storage, not from an earlier pending write. For example, re-read the committed value from originalContext.globalState in the catch path, or keep a committed-value snapshot that changes only after a successful update. Add a test that starts two overlapping writes to one key, rejects both, and asserts that getGlobalState returns the original value.

Refresh sibling views and their active tasks after a profile save.
