📝 WalkthroughWalkthroughChangesThe pull request adds durable checkpoint sealing across the relayfile store, mountsync, HTTP API, Go CLIs, and TypeScript SDK. It supports issuance, consumption, verification, handback, resume, recovery, strict validation, ownership checks, retention reconciliation, and idempotent retries. It also adds deterministic change-batcher timing. Checkpoint sealing
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR adds durable checkpoint and handoff behavior, but the current implementation can let one workspace interfere with another, reuse a checkpoint result for a different session or generation, and retire a mount before the source has actually stopped. That can cause incorrect handoffs or concurrent writes, so the changes should be fixed before merging. Suggested reviewers: Poem

When the mounted workspace uses a scoped remote path such as /notion—the path used throughout the SDK tests—this validation allows the checkpoint to proceed and performCheckpointAndSeal stops the live daemon, but the spawned Go implementation unconditionally rejects every remoteRoot != "/" in internal/mountsync/syncer.go:2433-2434. The real SDK flow therefore leaves any non-root mount stopped and returns checkpoint_seal_failed; validate the root before shutdown (as is already done for FUSE and pull-only mounts) or add scoped-root support.
Useful? React with 👍 / 👎.

Fixed at exact head bdaad365616304edfded9ab6bea0884688e71fb6. checkpointAndSeal now validates the daemon effective ambient plus per-call root configuration before performCheckpointAndSeal can call stop(), so non-root mounts fail deterministically while the daemon remains live. The hostile inherited-root regression and the focused mount-launcher suite pass; an independent exact-head review also exercised non-root rejection before stop.

When a mount-session token has only the ordinary fs:read/fs:write scopes (including the default response modeled by setup.test.ts), this line stops the daemon before discovering that sealing cannot succeed: Syncer.CheckpointAndSeal requires ops:read at internal/mountsync/syncer.go:2430-2431, and the HTTP checkpoint route additionally requires sync:trigger at internal/httpapi/server.go:226-228. Such calls deterministically fail after taking the mount offline, so the SDK should provision/require these scopes or reject the checkpoint before invoking stop().
Useful? React with 👍 / 👎.

Fixed at exact head bdaad365616304edfded9ab6bea0884688e71fb6. The preflight now parses the effective mount-session scope set using Go-compatible semantics and requires the checkpoint capabilities (ops:read, sync:trigger) plus an actual whole-root grant before the daemon is stopped. Tests cover inherited/per-call precedence, narrow / and /:secret rejection, /**, *, structured three-segment scopes, workspace full-namespace grants, and bare+narrow suppression; Go authoritative scope fixtures and the TypeScript suite are green.

purgeCheckpointSealsLockedskips every record whoseSourceResumedAtis empty. The fail-closed intent is correct: expiry is not proof of source resume. The consequence is that each abandoned lifecycle keeps one seal record in memory and in the persisted state file forever. Add an operational safeguard outside this function, for example a metric for the count of unresumed seals per workspace and an administrative reconciliation path, so a long-lived store cannot accumulate records without visibility.🤖 Prompt for AI Agents

seconds.

- Around line 1294-1588: Align the checkpoint-seal OpenAPI schemas with handler
behavior: set ttlSeconds.minimum to 0 so zero remains valid and receives the

checkpoint-seal operation, and make generation’s schema match the handler’s
uint64 range (or constrain the handler to signed int64). Preserve
sealToken.minLength at 32.
In `@packages/sdk/typescript/src/client.ts`:
- Around line 1663-1677: The issueCheckpointSeal method retries requests without
an idempotency key, preventing recovery when issuance commits before a response
is lost. Add a stable issuance idempotency key derived from the same operation
inputs and pass it through the request so retries replay the original checkpoint
seal, or disable retries specifically for issueCheckpointSeal if exact replay
support is unavailable.
In `@packages/sdk/typescript/src/mount-launcher.ts`:
- Around line 453-462: Validate that input.sessionId is a string before invoking
trim in checkpointAndSeal, and route missing or non-string values through the
existing RelayfileSetupError using code checkpoint_seal_invalid_input. Preserve
the current trimming and format validation for valid string session IDs.

- Around line 212-219: Update the MountLauncherInstance type contract so any
implementation providing checkpointAndSeal must also provide stopped, while
preserving stopped as optional for launchers without checkpointAndSeal. Adjust
the interface around MountLauncherInstance and use the existing member names
without changing runtime behavior.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift
Scope the issuance idempotency lookup to the workspace.
checkpointSealByIssuanceKeyLocked searches every seal in the store by IssuanceKeyHash alone. The hash is derived from the caller-supplied IssuanceIdempotencyKey only, so the key namespace is global across workspaces.
A caller authorized for workspace A can issue a seal with an arbitrary key value. A later caller in workspace B that uses the same key value matches that record. The request hash then differs (it includes workspaceID), so workspace B receives ErrCheckpointIssuanceConflict and can never issue that seal. This is a cross-workspace fencing gap that one tenant can trigger against another.
Bind the key to the workspace, either by hashing the workspace into the key hash or by comparing record.WorkspaceID during lookup.
🔒️ Proposed fix: namespace the issuance key by workspace
- if issuanceKey != "" {
- issuanceKeyHash = checkpointTokenHash(issuanceKey)
- }
+ if issuanceKey != "" {
+ issuanceKeyHash = checkpointTokenHash(workspaceID + "\x00" + issuanceKey)
+ }Alternatively, filter inside the lookup:
-func (s *Store) checkpointSealByIssuanceKeyLocked(keyHash string) (string, checkpointSealRecord, bool) {
+func (s *Store) checkpointSealByIssuanceKeyLocked(workspaceID, keyHash string) (string, checkpointSealRecord, bool) {
if keyHash == "" {
return "", checkpointSealRecord{}, false
}
for tokenHash, record := range s.checkpointSeals {
- if record.IssuanceKeyHash == keyHash {
+ if record.IssuanceKeyHash == keyHash && record.WorkspaceID == workspaceID {
return tokenHash, record, true
}
