Problem

Work chats could not show or act on a GitHub stack as a small peek, and GitHub stack merge/rebase on the PRs tab had no live proof.

Cause

PR↔chat edges were one-to-one and lane-scoped. Stack rebase via update-branch is rejected for stacked PRs. Merge-async polling waited 45s per layer, which exceeds the 30s ADE action timeout, so a three-layer squash timed out after the first PR.

Change and boundary

Hybrid edges plus dismissal tombstones, edges-first selectPrsForChat, human stack-link banner / agent silent-expand, atomic linkChatStack, GitHub stack Merge/Rebase on the PRs tab. Same RPC names on desktop, CLI, TUI, hosted web, and iOS.

Live GitHub: stacked update-branch copy is a missing stack-rebase API (disabled reason, not a generic failure). Merge-async poll cap is 8s per layer.

Did not add a git-rebase/force-push rebase path. Fixture PRs #1#18 on arul28/perf-pass were left alone.

Verification

96 focused desktop tests from the feature branch, plus 8 stack API/store tests after the live-proof follow-up (githubStackApi.test.ts 4, githubStackStore.test.ts 4).

Linux ADE (ADE_DISABLE_HARDWARE_ACCEL=1, DISPLAY=:1, Vite 5173) against arul28/perf-pass:

Work peek stack offer and Link stack
Three PR chips after Link stack
Peek switched to PR 21

Greptile Summary

This PR connects GitHub stack membership to Work chats across desktop, CLI/TUI, hosted web, and iOS, and adds stack merge/rebase operations with synchronized presentation and timeout handling.

  • Adds hybrid PR-to-chat links, dismissal tombstones, stack-link offers, and multi-PR Work peek selection.
  • Adds GitHub stack merge/rebase actions and confirmation, polling, fallback, and availability handling.
  • Propagates PR creation attribution and chat-session context across human and agent entry points.
  • Extends search, PR activity cards, mobile synchronization, and documentation for stacked PR workflows.
  • One non-blocking lifecycle concern remains in pending agent stack-attachment bookkeeping.

Confidence Score: 5/5

The PR appears safe to merge; the remaining stale pending-entry accumulation is a non-blocking lifecycle and performance concern.

Stack timeout, asynchronous completion, stale-SHA sequencing, action-specific availability, and atomic link rollback concerns from earlier reviews are addressed or resolved. The only new finding is that standalone agent-created PRs remain indefinitely in an in-memory retry map, which can gradually add repeated database work but does not break the stack or chat-link workflow.

apps/desktop/src/renderer/components/prs/shared/GitHubStackInspector.tsx Adds separately scoped merge/rebase availability, confirmations, and stack-identity guards for asynchronous results.
apps/desktop/src/renderer/webclient/adapter/prs.ts Extends hosted-web PR actions and reports residual links when compensating rollback cannot fully unlink a stack.
apps/ade-cli/src/tuiClient/app.tsx Adds chat-scoped PR catalogs, linked-PR headers/details, and captured chat context for PR creation.
apps/ios/ADE/Services/SyncService.swift Extends mobile synchronization and remote commands for PR-chat links and GitHub stack operations.

### Issue 1
apps/desktop/src/main/services/prs/prService.ts:7728-7730
**Pending Attachments Never Expire**

Every agent-created PR is added to `pendingAgentStackAttaches`, including standalone PRs that will never receive a GitHub stack entry. These entries have no expiry or cleanup for closed or merged PRs: removal only happens after stack membership is found. A long-running project service will therefore retain stale entries and repeat their database and attachment checks whenever another stack reconciles. Only queue PRs that may still gain stack membership, or remove entries after a bounded retry or lifecycle transition.

Context used (3)

Work peek stays a peek: #N header, chip switcher, three churn-ranked
files, and a stack-offer banner. Merge and rebase live on the PRs tab.
Palette #N jumps to linked chats; a landed GitHub stack emits one
stable pr_stack_land card across every linked Work chat.

📝 Walkthrough

Walkthrough

The PR adds GitHub stack merge/rebase operations, chat-session PR linking, chat-scoped PR selection, stack cards, and desktop and iOS integrations. It also adds persistence, sync, IPC, CLI, UI, and test coverage.

Changes

PR contracts, scoping, and persistence

Layer / File(s) Summary
Shared PR and chat contracts
apps/desktop/src/shared/*, apps/ios/ADE/Models/*, apps/ios/ADE/Resources/*
Adds stack mutation results, chat-link fields, dismissal tracking, stack-card variants, sync actions, error helpers, and chat-scoping utilities.
PR service and GitHub stack mutations
apps/desktop/src/main/services/prs/*
Adds stack merge/rebase operations, chat-session linking and unlinking, stack-link offers, dismissal persistence, fallback polling, and cleanup.
Remote and IPC wiring
apps/ade-cli/src/*, apps/desktop/src/preload/*, apps/desktop/src/shared/ipc.ts
Adds CLI commands, sync parsers, IPC handlers, preload methods, timeout entries, permissions, and mobile compatibility actions.

PR creation, cards, settlement, and search

Layer / File(s) Summary
PR creation and stack cards
apps/ade-cli/src/adeRpcServer.ts, apps/ade-cli/src/bootstrap.ts, apps/desktop/src/main/main.ts, apps/desktop/src/main/services/prs/prChatCards.ts, apps/desktop/src/renderer/components/chat/AdeCard.tsx
PR creation records session and source metadata. Polling passes the full PR snapshot. Fully landed stacks emit stack cards to linked chats.
Merge settlement and search
apps/desktop/src/main/services/prs/prMergeAutoSettlementService.ts, apps/desktop/src/main/services/search/searchService.ts
Settlement follows explicit chat links, defers sessions with other open linked PRs, and excludes chat sessions from lane sweeps. PR-number search returns linked chat results.

Desktop and iOS interfaces

Layer / File(s) Summary
Desktop chat PR surfaces
apps/ade-cli/src/tuiClient/*, apps/desktop/src/renderer/components/chat/*, apps/desktop/src/renderer/components/terminals/*
Chat views select PRs by session and branch, display linked PR chips, show file previews, support stack offers, and provide link/unlink controls.
Desktop stack controls
apps/desktop/src/renderer/components/prs/*
Stack inspection adds merge and rebase actions, confirmation states, merge-method selection, unavailable reasons, and mutation result handling.
iOS stack and chat PR integration
apps/ios/ADE/Services/*, apps/ios/ADE/Views/*, apps/ios/ADETests/*
iOS sync and database layers support stack mutations and chat links. PR detail and work-chat views support stack actions, linked PR selection, file previews, stack offers, and link/unlink flows.

Problem
Silent parent-stack attach, GitHub App 403s, and a failed Link stack
tap could hide or disable stack merge/link on every client.

Cause
Quality synthesis treated stack-API 403 as a hard disable, the merge
lock deadlocked on nested reconcile, and the peek dismissed the stack
offer without checking linkChatStack.ok.

Change and boundary
Agent-only silent parent attach, 202 merge confirmation, atomic
linkChatStack, GitHub App 403 falling through to merge-async, and
failed/partial stack links leaving the Work offer visible. Nested
stack mutations now refresh via replaceFromRemote instead of
re-entering the repo lock. Desktop, CLI, TUI, hosted web, and iOS
share the same RPC names. Windows stays GitHub HTTP + SQLite.

Verification
96 focused desktop tests (prChatScope, githubStackApi, githubStackStore,
prChatCards, ChatPrPane, ChatGitToolbar, AdeCard, useLanePrs).

Co-authored-by: Arul Sharma <arul28@users.noreply.github.com>
GitHub's stack rebase route 404s and update-branch rejects stacked PRs, so classify that copy as a missing stack-rebase API. Cap merge-async polling at 8s so a three-layer squash stays under the 30s ADE action timeout.

Give stack merge/rebase a long-running runtime budget, compare chat links to
the session lane, roll back partial stack links, and keep merge available when
rebase is unavailable. Honor {ok:false} on desktop and iOS, preserve the TUI
catalog when listAll fails, and update the tests CI already failed.

Poll merge-async until GitHub reports merged or the four-minute budget ends,
restore prior unlink tombstones on linkChatStack rollback, send ordinary PR
cards only to that PR's chats, and split iOS merge/rebase unavailable state.
Web and iOS fallback stack-link now rolls back partial links.

A 202 GitHub stack merge now polls every still-open PR, rebase waits for each
head SHA to move, unlink rolls back if the dismissal tombstone cannot be
written, and the TUI drops the previous project's PR catalog when the
connection changes. Also unblocks typecheck on a possibly-null stack number.

Stack merge now loads membership from GitHub after HTTP 202 before polling.
Fallback rebase reads the live head SHA before each update-branch. TUI PR
chips clear only when the connection object changes. Cross-lane linked chats
get cards via getSessionSummary. Web/iOS stack-link rollback unlinks without
writing dismissal tombstones.

Inline comments:
In `@apps/ade-cli/src/adeRpcServer.ts`:
- Around line 5516-5517: Authorize the explicit sessionId in the handler before
createFromLane uses it: accept it only when it belongs to the caller represented
by session.identity.chatSessionId, otherwise reject the request, while
preserving the implicit identity-session behavior. Ensure the
linkPrToChatSession path cannot receive an unauthorized ID, and add coverage
proving a different valid session ID is rejected without creating a link.

In `@apps/ade-cli/src/services/sync/syncRemoteCommandService.ts`:
- Around line 3314-3316: Validate mergeMethod before constructing the arguments
for prService.mergeGithubStack: allow only "merge", "squash", or "rebase", and
reject any other non-empty value instead of omitting it. Preserve the existing
handling for supported values and empty or absent input.

In `@apps/ade-cli/src/tuiClient/app.tsx`:
- Around line 12919-12920: Update the PR creation payload in submitRightForm to
use the already-fresh local sessionId from activeSessionIdRef.current instead of
activeSession?.sessionId or activeSessionId state, preserving the existing
source value.

In `@apps/desktop/src/main/services/localRuntime/localRuntimeTimeoutPolicy.ts`:
- Around line 144-145: Change the timeout keys for mergeGithubStack and
rebaseGithubStack from prs.* to pr.* in localRuntimeTimeoutPolicy.ts, matching
the preload bridge domain and exact lookup format. Update the corresponding
expectations in localRuntimeTimeoutPolicy.test.ts lines 27-28 to use pr.* as
well.

In `@apps/desktop/src/main/services/prs/prChatCards.ts`:
- Line 554: Update the ordinary-card fallback around selectPrCardSessions so its
candidate sessions are filtered to pr.laneId before selection, preventing
sibling-layer chats from being chosen when linkedIds is empty. Preserve the
existing cross-stack session set for pr_stack_land.
- Around line 510-512: Update emitPrCardsForChange around
stackSiblings/stackLayers so a stack-land card is considered only when the
selected stack members count equals pr.stack.size; otherwise treat the stack as
incomplete and prevent isGithubStackFullyLanded/buildPrStackLandCard from being
used. Preserve the existing behavior for complete stacks and for PRs without
stack metadata.

In `@apps/desktop/src/main/services/prs/prService.ts`:
- Around line 12389-12392: Update linkChatStack so it returns { ok: false,
linked: 0 } when the computed unclaimed siblings collection is empty, before
attempting to link siblings; preserve successful results only when at least one
sibling is actually linked.

In `@apps/desktop/src/main/services/search/searchService.ts`:
- Around line 1410-1413: Update the delegated PR/chat result path after parsing
prNumber to build the candidate chat haystack, reject sessions that fall outside
the requested filters such as since:, and apply matchesAllTerms so parsed terms
and phrases are enforced before returning the linked chat. Preserve the existing
early exits and only add candidates that satisfy the normal search matching
contract.

In `@apps/desktop/src/renderer/components/chat/ChatGitToolbar.tsx`:
- Around line 573-576: Update the PR toolbar click flow around onTogglePrPane
and ChatPrPane so it passes candidate through a parent-provided PR-selection
callback and invokes that callback before opening or focusing the pane. Ensure
both closed and already-open panes select the clicked PR, while preserving
openPr(candidate) when no pane toggle handler is provided.

In `@apps/desktop/src/renderer/components/chat/ChatPrPane.tsx`:
- Line 424: Centralize PR selection in a helper that clears checks, reviews,
status, relay, and peekFiles before calling setPr. Update applyScopedPrs, the PR
tab handler, and every other PR refresh or selection path to use this helper,
ensuring stale details are removed immediately even when relay fetching fails or
is skipped.
- Line 730: Update the linkPr and unlinkCurrent operations to catch rejected
linkChatSession and unlink requests, respectively, and pass the caught error
through the same user-visible error handling used for { ok: false }. Preserve
their existing finally cleanup behavior while preventing rejected requests from
becoming unhandled rejections.

In `@apps/desktop/src/renderer/components/prs/shared/GitHubStackInspector.tsx`:
- Line 155: Update the request handling around onMerge and onRebase in
GitHubStackInspector to capture the current stack.id before awaiting each
operation, then compare it with a ref tracking the latest stack.id before
invoking applyMutationResult. Skip stale results when the IDs differ, preventing
an earlier stack’s response from updating the newly selected stack.
- Line 87: Update the reset effect in GitHubStackInspector to depend on the full
stack identity, including GitHubPrStack.id rather than only stack.number, so
switching repositories or stacks with the same number clears pending
confirmation and unavailable reasons before reuse.

In `@apps/desktop/src/renderer/components/prs/tabs/GitHubTab.tsx`:
- Line 599: Update the post-mutation snapshot refreshes in mergeGitHubStack and
rebaseGitHubStack to call loadSnapshot with both silent and force enabled,
ensuring each stack mutation fetches a fresh snapshot rather than reusing an
in-flight request.

In `@apps/desktop/src/renderer/components/terminals/SessionListPane.tsx`:
- Line 2042: Update the sessionPr selection near selectPrimaryLanePr so a PR
explicitly linked by the chat remains selectable even when its laneId differs
from sessionLane: use the first scoped PR from chatPrs as the fallback, matching
ChatPrPane, while preserving the primary-lane PR preference when available.

In `@apps/desktop/src/renderer/webclient/adapter/prs.ts`:
- Around line 349-354: Update the rollback loop around linkedIds.reverse() and
prs.unlinkChatSession to inspect every compensation result. If any unlink fails,
do not report linked: 0; instead return the accurate number of links that
remain, preserving the atomic stack-link contract, or disable this fallback when
atomic host support is unavailable.

In `@apps/ios/ADE/Views/PRs/PrDetailOverviewTab.swift`:
- Around line 898-931: Update the stack mutation confirmation flow around
githubStackConfirm and the rebase/merge button actions to provide an explicit
way to cancel an armed confirmation, and reset it when the user leaves the
screen or the relevant context changes. Preserve the existing confirmation
requirement and successful mutation behavior for both rebase and merge.

In `@apps/ios/ADE/Views/PRs/PrDetailScreen.swift`:
- Line 1759: Update the single-PR merge confirmation path around
performGithubStackMutation(action: "merge") to invoke the stack-specific
confirmation flow instead of merging the entire stack directly. Preserve
single-PR behavior when stack membership loads after the sheet opens, and
require explicit stack confirmation before any stack-wide merge.
- Line 1779: Update the confirmation state around githubStackConfirm to store
both the action and the associated nativeStackMembership.number, and require
both values to match before confirming. When the stack identity changes, clear
the stored confirmation and unavailable reasons so stale state cannot affect the
new stack.

IDOR

CWE: CWE-639 — Authorization Bypass Through User-Controlled Key (IDOR)

Authorize the explicit sessionId before linking the PR.

The externally exposed tool accepts sessionId, and the handler uses it instead of session.identity.chatSessionId. createFromLane forwards it to linkPrToChatSession with allowCrossLane: true. The helper validates that the session exists, but does not verify caller ownership before writing the link. A caller who knows another valid session ID can associate the new PR with that session.

Reject unauthorized explicit IDs, or bind the link to session.identity.chatSessionId. Add a test that rejects a different valid session ID without creating the link.

Skipped as invalid vs product: create_pr_from_lane is an in-project agent tool. Passing sessionId is the same explicit chat pick as the desktop/TUI picker (allowCrossLane: true after the session is verified to exist). Binding only to session.identity.chatSessionId would break opening a PR for a chosen sibling chat in the same project. Fixed in f2522c7b4 instead: empty linkChatStack offers now return { ok: false }, unsupported remote mergeMethod is rejected, and TUI pr-open uses the form's captured session id.

Use the already-fresh sessionId, not stale activeSession/activeSessionId state.

This line reads activeSession?.sessionId ?? activeSessionId ?? null directly from component state. submitRightForm's useCallback dependency array does not include activeSession or activeSessionId. The callback keeps its old closure until a listed dependency changes, so it can hold a stale session id after the user switches chats.

submitRightForm already computes the current session id from a ref at the top of the function: const sessionId = activeSessionIdRef.current;. Every other command branch in this function reuses that local variable. Use it here too. Otherwise the created PR can persist the wrong sessionId, breaking the PR-to-chat link this layer establishes.

🐛 Proposed fix
       const created = await conn.action("pr", "createFromLane", {
         laneId,
         title,
         body,
         draft: false,

Require a complete stack before emitting a stack-land card.

emitPrCardsForChange accepts optional relatedPrs. Its production callers pass prService.listAll(), but listAll() reads only pull_requests, so it can omit stack members without mapped rows. selectStackSiblings then returns a partial list, and isGithubStackFullyLanded checks only that list. A merged PR can therefore emit a buildPrStackLandCard with incomplete layers. The helper also permits direct callers to omit relatedPrs.

pr.stack.size represents the stack entry count. Require the selected stack members to match that count before evaluating completion.

Proposed fix
 const stackSiblings = args.relatedPrs ? selectStackSiblings(args.relatedPrs, pr) : [];
-const stackLayers = stackSiblings.length > 0 ? stackSiblings : [pr];
-const stackLanded = merged && pr.stack != null && isGithubStackFullyLanded(stackLayers);
+const hasCompleteStack = pr.stack != null && stackSiblings.length === pr.stack.size;
+const stackLayers = hasCompleteStack ? stackSiblings : [];
+const stackLanded = merged && hasCompleteStack && isGithubStackFullyLanded(stackLayers);

Skipped: emitPrCardsForChange already receives the full polling snapshot (relatedPrs: prs in main.ts), not a truncated sibling list. Stack land uses selectStackSiblings over that snapshot. The remaining card-routing bug (unlinked member falling into a sibling chat) is fixed on f2522c7b4 by building ordinary recipients from this PR's lane + explicit edges only.

Ordinary CI cards stay on the changed PR's lane, agent stack layers attach
from the parent stack even before GitHub membership lands, and stack merge
timeouts, empty link-stack offers, peek switching, and iOS confirm/cancel
match the review threads that were still correct.

P2 Pending Attachments Never Expire

Every agent-created PR is added to pendingAgentStackAttaches, including standalone PRs that will never receive a GitHub stack entry. These entries have no expiry or cleanup for closed or merged PRs: removal only happens after stack membership is found. A long-running project service will therefore retain stale entries and repeat their database and attachment checks whenever another stack reconciles. Only queue PRs that may still gain stack membership, or remove entries after a bounded retry or lifecycle transition.

🟡 Agent PR tracking grows forever

Every agent-created PR enters pendingAgentStackAttaches, including PRs that never join stacks. Those entries persist and repeat database work after every reconciliation.

Learn more

pendingAgentStackAttaches is process-lifetime state used to retry parent-chat attachment until stack membership appears. The cleanup in onReconciled deletes an entry only after finding a github_pr_stack_entries row. Agent tools set source: "agent" for all PR creations, not only known stack layers, so ordinary PRs never satisfy that cleanup condition. Every later stack reconciliation then reruns attachNewStackLayerToParentChats for all retained ordinary PRs.

Example: An agent creates 100 independent PRs over a long-running brain process. All 100 remain in the map. Each later stack reconciliation performs parent, PR, and stack lookup queries for every retained PR.

Recommended fix: Add pending entries only when the lane is a plausible child stack layer, or expire/delete entries after stack reconciliation establishes that the PR is not a member. Keep retries bounded while membership propagation is pending.

🟡 Link failures escape the PR pane

Rejected linkChatSession or unlinkChatSession calls escape without setting linkError. Runtime failures leave the pane unchanged and create an unhandled rejection.

Learn more

The callbacks handle successful responses and explicit { ok: false } responses, but neither has a catch. The click handlers discard the returned promises with void, so transport failures reject outside React and do not reach the pane's existing error UI. The stack-link callback already catches the same failure class.

Example: A remote runtime disconnects after the user clicks “Link another PR.” window.ade.prs.linkChatSession rejects. The picker remains open without an explanation, and the browser reports an unhandled promise rejection.

Recommended fix: Catch exceptions in both linkPr and unlinkCurrent, set the operation-specific linkError, and retain the current picker or linked state for retry.

🟡 Stale stack errors replace selection

A rejected onMerge or onRebase writes its error after the selected stack changes. The new stack then displays the previous stack’s failure.

Learn more

Each mutation captures requestedStackId, and fulfilled results are ignored when stackIdRef has changed. Rejections bypass that identity check and call setError unconditionally. The component remains mounted while its stack prop changes, so an old request can finish against a new selection.

Example: Stack #4 begins merging, the user selects stack #5, and stack #4's request rejects. Stack #5 displays “GitHub could not merge this stack,” although no merge was attempted for it.

Recommended fix: Apply the same stackIdRef.current === requestedStackId guard in both catch blocks before updating error state. Preserve the busy-state cleanup needed by the mounted inspector.

🟡 Stale stack results cross selections

A completed stack mutation updates state without verifying the current stack. Navigating meanwhile can apply old errors or reload the newly selected PR.

Learn more

performGithubStackMutation captures membership, then awaits a remote command inside an unstructured task. The detail screen can change currentPr and nativeStackMembership while that command runs. Every success, unavailable result, and thrown error then updates state for whichever PR is currently displayed.

Example: A rebase starts for stack #4, then the user opens a PR in stack #5. A delayed “unavailable” result from stack #4 disables rebase and shows its reason on stack #5.

Recommended fix: Capture a stable stack and PR identity before launching the task. After every await and before each state update or reload, verify that the current membership still matches that identity.
