Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

📝 WalkthroughWalkthroughThe change adds a complete web server stack. It includes runtime configuration, session persistence, agent and client WebSocket handling, command routing, HTTP APIs, daemon ownership, discovery state, managed-session recovery, and server lifecycle orchestration. ChangesWeb server stack
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This refactor changes server composition and WebSocket/session lifecycle behavior; the current head can accept unauthenticated agent frames, allow messages to affect another session, leak temporary sessions on startup failure, stall queued writes, and hang startup or shutdown indefinitely. These create concrete security and availability risks, so the PR is not merge-ready without fixes or explicit acceptance. Sequence Diagram(s)sequenceDiagram

Break the 3,945-line single-file web daemon into focused modules with camelCase filenames, following the existing factory + dependency-injection pattern (createSessionQueueCoordinator, createSessionFileCatalog): - serverConfig / serverRuntimeState / serverStores: env config, shared mutable state, and durable sidecar stores - stateFileStore / discoveryState: state-file persistence and the webState/Tailscale Serve publishing pair - sessionRegistry / sessionHistory / recordSync / missingSessions: the live session catalog, bounded history, runtime state application, and missing-file predicates - clientBroadcast / gitMetadata / rpcSessions / compactionNotice: socket fan-out, git/gh metadata hydration, RPC session factory, and compaction completion notices - managedSessionCreate / managedSessionRefresh / sessionReplacement: managed RPC session lifecycle, transactional identity refresh with staged-deletion recovery, and external replacement commit - commandRouter / clientMessages / agentMessages: command routing with the slash command service, and the browser/agent WebSocket handlers - sessionDeletion / httpApi / webSocketGateway: durable deletion and reconciliation, the REST API, and the WebSocket endpoint - daemonOwnership / serverLifecycle / webServerApp: ownership arbitration, startup/shutdown, and the composition root wiring the two genuine dependency cycles (queue coordinator <-> router, registry <-> deletion) with late-bound references index.ts remains the entry point (15 lines) so `bun run web/server/index.ts` and daemon detection keep working. Pure structural move; all 353 tests pass unchanged.

Inline comments:
In `@web/server/agentMessages.ts`:
- Around line 335-343: Enforce socket ownership in both handlers in
web/server/agentMessages.ts:335-343 and web/server/agentMessages.ts:396-411. In
the agent.subagents handler, update the record lookup guard to also require
record.agentSockets.has(socket); in the response handler, compare
record.externalRequestTargets.get(response.requestId) with socket before
settling the pending promise. Use the existing record, socket, and response
symbols without changing unrelated handlers.
- Around line 97-99: Require valid agent credentials during the `/ws/agent`
upgrade or before processing any agent frame, and do not set
`socket.data.authed` merely because the message type is `agent.hello`. Update
the `agent.hello` handling and related upgrade authentication flow to validate
the configured token, reject unauthenticated connections or frames, and only
mark the socket authenticated after successful validation.
In `@web/server/commandRouter.ts`:
- Around line 110-151: Move the await temp.start() call inside the existing try
block that wraps the command switch, ensuring temp.shutdown() always runs when
startup or command execution fails. Keep the existing command handling and
finally cleanup unchanged.
In `@web/server/compactionNotice.ts`:
- Around line 15-23: Update broadcastCompactionNotice to explicitly consume any
rejection from record.compactionHistoryRefresh after attaching the finally
delivery callback, ensuring the promise created by finally cannot produce an
unhandled rejection; keep the existing deliver behavior and immediate path when
no refresh exists unchanged.
In `@web/server/gitMetadata.ts`:
- Around line 49-56: Update hydrateGitMetadata so the independent branch and
pull-request commandOutput calls run concurrently, then await their combined
results before constructing the metadata. Preserve the existing command
arguments, cwd, timeout behavior, and result handling.
In `@web/server/httpApi.ts`:
- Around line 312-359: Update the session-creation catch block around
createManagedSession so failures return a structured jsonResponse error with
HTTP 500 instead of rethrowing. Preserve the existing initial-session cleanup
and worktree-retention behavior, but ensure both worktree and non-worktree
failures use the same { error } response shape.
In `@web/server/managedSessionCreate.ts`:
- Around line 186-194: Merge the adjacent event-type checks in managed session
handling into one condition containing all related statements, preserving their
existing order and behavior; apply the same consolidation in the corresponding
agent message handling logic in agentMessages.ts.
In `@web/server/managedSessionRefresh.ts`:
- Around line 333-360: Update the tombstone scan around the recursive directory
traversal to use a single readdirSync call with recursive and withFileTypes
options, relying on Dirent parentPath and name to construct each full path.
Preserve the existing tombstone filename matching and per-directory
unreadable-directory behavior as supported by the recursive API.
In `@web/server/missingSessions.ts`:
- Around line 17-44: Update hasStagedOrDurableReplacement and its callers so one
reconciliation pass reuses a single scanSavedSessions(sessionsDir) result
instead of scanning once per record. Thread an optional precomputed scan list
through isMissingInactiveSession from sessionSnapshot and
reconcileMissingSessionFiles, while preserving the existing behavior when no
list is supplied.
In `@web/server/serverConfig.ts`:
- Around line 51-72: Update the port parsing near configuredPort in the server
configuration to trim PI_WEB_PORT and fall back to DEFAULT_WEB_PORT when the
trimmed value is empty, while preserving an explicit "0" as valid. Keep the
existing integer and range validation for non-empty values and the initialPort
assignment behavior.
In `@web/server/serverLifecycle.ts`:
- Around line 74-91: Update cleanupAndExit’s managed-shutdown wait loop to
enforce a maximum wait duration, so shouldContinueManagedShutdownWait cannot
keep it blocked indefinitely when sessions remain busy. Preserve the existing
polling and busy-session reporting, and exit the wait once the timeout is
reached even if busy sessions never settle.
- Around line 151-163: Define a WEB_BUILD_TIMEOUT_MS constant and pass it as the
timeout option in the Bun.spawn call for the webBuild process, ensuring a hung
client asset build cannot block server startup or state-file creation while
preserving the existing exit-code handling.
In `@web/server/sessionDeletion.ts`:
- Around line 300-311: Use normalizePath consistently as the key contract for
runtime.sessionsByFile and runtime.managedSessionStarts: update
web/server/sessionDeletion.ts lines 300-311 and 385-392 to derive lookup keys
with normalizePath(record.file) and normalizePath(initialSessionFile), and
retain or document normalizePath usage in web/server/managedSessionCreate.ts
lines 402-413. If appropriate, export a shared key helper used by both modules,
ensuring deleteSession can await in-flight managed starts and stale records are
removed from both maps.
In `@web/server/sessionHistory.ts`:
- Around line 56-69: Update the module header comment to state that
sessionHistoryForRecord lazily hydrates file-backed records and mutates
record.history, record.historyReady, and record.historyBytes through
replaceRecordHistory; remove the claim that the module is pure.
- Around line 38-53: Add a non-empty history guard to the trimming loop in
boundedWebHistory, alongside the existing entry and byte-limit conditions, so it
stops when record.history has no elements even if record.historyBytes remains
above the limit. Preserve the existing removal and summary-preservation behavior
for non-empty histories.
In `@web/server/sessionRegistry.ts`:
- Around line 33-34: Update the reconcileMissingSessions hook type in the
session registry options to allow void or Promise<void>, then handle any
rejected promise at its invocation in the session reconciliation flow by
attaching a rejection handler that logs a warning. Preserve the existing
synchronous behavior and call timing.
- Around line 96-119: Update makeSessionRecord so displayHistory is computed
only for a newly created session record, or reuse the existing record.history
when runtime.sessions already contains session.id. Preserve the current history
projection and initialization behavior for new records while avoiding
buildContextEntries and boundedWebHistory work on existing-record paths.
- Around line 133-134: Remove the redundant active assignment in the
session-record update: simplify the logic around record.active so the saved-kind
behavior is expressed by one assignment, preserving the existing behavior for
all other kind values.
In `@web/server/sessionReplacement.ts`:
- Around line 102-125: Update the session replacement flow around
quiesceQueueMutations and the queueStoreWriter.mutate catch so reopening
previous.queueMutationsQuiesced after a failed store write also restores a retry
timer for the retained queue when needed. Preserve the existing timer callback
and flushWebQueue behavior by reusing the established queue retry scheduling
mechanism rather than leaving the queue without a pending retry.
In `@web/server/webServerApp.ts`:
- Around line 53-62: Change the initial reconcileMissingSessions binding in the
session registry setup to throw immediately when invoked before its later
reassignment, matching the fail-fast behavior of the deliverCommand binding;
retain the existing reassigned implementation for normal execution.
In `@web/server/webSocketGateway.ts`:
- Around line 44-69: Remove the socket.data assignments and randomUUID
generation from attachClientSocket and attachAgentSocket; retain the
upgrade-time initialization in serverLifecycle.ts so each socket keeps the same
id throughout its lifecycle. Update handleWebSocketOpen to avoid reattaching or
replacing socket metadata while preserving the client/agent distinction.

- agentMessages: enforce per-session socket ownership for agent.event,
agent.subagents, agent.update, and agent.response so a bridge frame
cannot mutate sessions it has not been bound to. Defer setting
socket.data.authed until after the agent.hello session record is
created and the socket is bound to it.
- commandRouter: start the temporary managed session inside the
existing try/finally so temp.shutdown() always runs on failure.
- compactionNotice: consume rejection from the compaction history
refresh so its finally callback cannot produce an unhandled rejection.
- gitMetadata: run git branch and gh pr view concurrently.
- httpApi: return structured HTTP 500 jsonResponse errors for managed
session creation failures instead of rethrowing.
- managedSessionCreate: merge adjacent agent_start/turn_start checks.
- managedSessionRefresh: switch the tombstone scan to a single
recursive readdirSync({recursive, withFileTypes}) call.
- missingSessions: thread an optional precomputed scan list through
hasStagedOrDurableReplacement / isMissingInactiveSession so one
reconciliation pass reuses a single scanSavedSessions result.
- serverConfig: trim PI_WEB_PORT and fall back to DEFAULT_WEB_PORT
when the trimmed value is empty.
- serverLifecycle: bound the managed-shutdown wait with a max
duration and add a WEB_BUILD_TIMEOUT_MS for the client asset build.
- sessionDeletion: route sessionsByFile/managedSessionStarts lookups
through sessionFileKey (= normalizePath) so keys match producers
and document the shared key contract.
- sessionHistory: add a non-empty history guard to the trim loop and
correct the module header to reflect lazy-hydration side effects.
- sessionRegistry: type reconcileMissingSessions as void | Promise<void>,
consume its rejection at the snapshot call site, only compute
displayHistory for new records, share the scan across the snapshot
pass, and drop the redundant record.active assignment.
- sessionReplacement: restore the queue retry timer after a failed
store write so the retained queue does not stall.
- webServerApp: make the late-bound reconcileMissingSessions fail fast
before its reassignment, matching the deliverCommand binding.
- webSocketGateway: stop reassigning socket.data in the open handler;
upgrade-time initialization is the single assignment site.

Summary
web/server/index.tshad grown to 3,945 lines mixing config, session state, RPC lifecycle, command routing, WebSocket handling, the REST API, and daemon startup. This PR breaks it into focused modules with camelCase filenames, following the codebase's existing factory + dependency-injection pattern (createSessionQueueCoordinator,createSessionFileCatalog).New layout (
web/server/)serverConfig.tsserverRuntimeState.tsserverStores.tsstateFileStore.ts/discoveryState.tssessionRegistry.ts/sessionHistory.ts/recordSync.ts/missingSessions.tsclientBroadcast.ts/gitMetadata.ts/rpcSessions.ts/compactionNotice.tsmanagedSessionCreate.ts/managedSessionRefresh.ts/sessionReplacement.tscommandRouter.ts/clientMessages.ts/agentMessages.tssessionDeletion.ts/httpApi.ts/webSocketGateway.tsdaemonOwnership.ts/serverLifecycle.ts/webServerApp.tsindex.tsThe two genuine dependency cycles (queue coordinator <-> command router, registry <-> deletion) are resolved with late-bound references in the composition root instead of module-scope hoisting.
