Merge Risk: 🟡 Moderate · up to The permission hardening still leaves gaps. A dangling project symlink can let a write land outside the project without approval, and denied filenames can appear in search errors. Native calls can start for a closed window. Live views can miss updates or keep showing a deleted chat after reconnecting. Resolve these before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The changes strengthen permission enforcement and recovery, but file-access safeguards still have limitations, and denied requests can reveal private path metadata. The remaining exposure depends on the desktop user's permissions and enabled tools; broader access across accounts or services has not been established. Retained concerns

Full details: Docstring CoverageExplanation Docstring coverage is 28.57% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 14 functions across 28 files. (9 skipped: 9 unsupported.) Full details: Description checkExplanation The description provides a useful summary, verification results, and boundaries, but it does not follow the required template. It omits the How to try it, Honest states, Risk and rollback, and Attestation sections, and it does not include the required attestation responses. Resolution Add all required template sections: What changed, How to try it, Honest states, Verification, Risk and rollback, and Attestation. Include the applicable route and reproduction steps, changed empty/loading/error states, rollback risks, and a checked or explicitly explained response for every attestation item.

Review comments at @packages/app/src/screens/chat/live-chat.tsx:
- Line 351: Update the delete failure handler in `onClose` to check whether the
current route is still the Chat screen for this session before calling
`go("chat", { id })`. Always show the error toast, but do not navigate if the
user has moved to another screen while the DELETE request was pending.
Review comments at @packages/app/src/state/live.ts:
- Around line 17-18: Update the recovery flow around connect and resync so
refreshes run only after the replacement subscription is established, closing
the gap between the snapshot and stream. Retry any refresh that fails so queries
or messages are refreshed after an outage.
- Line 108: Update the rejection handler in refresh so it preserves existing
behavior for transient fetch failures, but when the live session receives a
not_found error, clear records and settled, reset status to idle, and publish
the updated state.
Review comments at @packages/core/src/tool.ts:
- Line 141: Update the search permission-check flow around ctx.ask(abs, ...) so
permission_denied errors do not expose denied candidate paths; apply the same
handling to grep. Keep checking read permission before returning names or
reading contents, and update the denied-file test to verify the filename is
absent from tool errors.
- Line 57: Update candidate-file handling around the realpath resolution so
pathname validation and reading cannot be separated by a symlink replacement.
Open the candidate without following replacement symlinks, validate the opened
file through its descriptor, and have grep read from that same descriptor rather
than reopening abs by pathname.
- Around line 57-60: Update the `target()` path resolution flow so an `ENOENT`
from `realpath(parent)` does not treat a dangling symlink as a missing path
component; detect and reject or safely resolve dangling symlinks before
reconstructing the pathname, preserving the existing missing-component behavior
for ordinary paths.
Review comments at @packages/desktop/src/remote-call.ts:
- Around line 53-54: Update the start flow in remote-call so owner cancellation
is registered before awaiting auth(origin). After authentication completes,
reject the start if the initiating WebContents was lost, preventing creation of
a server call for a destroyed renderer.

Backend #525 repacked api-types 0.3.8 after merging #524 so it keeps turn_error. Copy the archive byte for byte from backend main apps/web/vendor and update the lock integrity and vendor README hash. SDK 0.4.9 bytes are unchanged.
File tools follow dangling symlinks before external-directory checks and read approved paths through one descriptor, refusing a link swapped in after approval. Per-candidate glob/grep refusals no longer reveal the denied filename. The live bus resyncs only after the replacement stream opens and keeps a failed reopen pending; a deleted session clears its messages on resync. A delete failure no longer pulls the user off a screen they opened. A Bot call start refuses an owner window lost during authentication.

Summary
Repair independently reproduced desktop permission, native-session and UI
recovery defects. Preserve parent deny rules, per-file read and symlink boundary
checks, PATCH omission semantics, MCP/desktop consent and skill discovery.
Correct call ownership, credentials recovery, UTF-8 request decoding, SSE/Code
reconnect, missing-ID history and failed-deletion feedback. Include AGENTS.md and
the audit report; adopt SDK 0.4.9/API types 0.3.8.
