Problem

When the agents slice is throttled for memory, every agent freezes and nothing in T3 says why. Turns just keep saying Working.

Fix

Server (HostResources) reads memory pressure:
- Linux: PSI /proc/pressure/memory for the host, plus the agents slice's memory.pressure, located through the new AgentScope.controlGroups.
- macOS: kern.memorystatus_vm_pressure_level, read by the already-running native resource monitor through sysctlbyname. Sampling never spawns a process: under memory pressure a new process may fail to start, which is exactly when the reading matters. The sidecar answers a new memoryPressure command; releases build and bundle it from the same commit as the server.
Derived level none / elevated / severe, with hysteresis: a level is entered above its threshold and left only well below it, so it does not flicker.
- Elevated: host full ≥ 2 %, host some ≥ 10 %, or agents full ≥ 5 %.
- Severe: host full ≥ 10 %, agents full ≥ 20 %, or macOS critical.
- The agents slice gets looser thresholds because the kernel throttles it first.
Heaviest agents. While pressure is not none, the top three agent scopes by memory.current are included with their thread (shared processes appear as e.g. codex (shared)). Sizes are rounded to about 1/8 of their magnitude so normal growth doesn't push an update every sample.
Transport.
- HostResourcesSnapshot gains an optional memoryPressure.
- Clients that opt in with memoryPressure: true (capability memoryPressure) get memoryPressureUpdated on the config stream, mirroring how usageLimitSources was added so older clients never see an unknown event type.
- Sampling is a Stream.shared 5 s poll that runs only while someone listens, and emits only on change.
- The payload carries only the level and the heaviest agents; raw stall percentages changed every sample and no client read them. A none update that changes nothing leaves the client's config untouched, so nothing re-renders.
- When no source can be read for 30 s (for example a dead sidecar), the level falls back to none, so a warning cannot outlive the pressure.
- Pressure is never cached and is carried across reconnect snapshots.
- No protocol version bump is needed: the field is optional and the event is opt-in.
Web. A warning pill in the sidebar footer, "Low on memory", appears only while severe. Its popover names the heaviest agents with links to their threads and Force stop from the previous layer.
Mobile. The same as a banner at the top of the thread list, with a confirmation before Force stop.

Verification

Tests:
- PSI parsing and a hysteresis table, including the incident's throttled-agents reading and macOS critical.
- Agent memory rounding (regression: a 28 MB agent used to round to 0 and vanish from the list).
- AgentScope.controlGroups maps scopes to threads in the fake-systemd harness.
- The config projection carries pressure across a reconnect snapshot, drops it once pressure ends, and ignores a none update when nothing is stored.
- On macOS a sidecar that stops answering clears a severe level after 30 s.
- On macOS, HostResources takes the level from the sidecar; the test's spawner fails if sampling spawns anything (it did before).
- The sidecar's Rust tests ran on macOS (macmini), where memoryPressure returned level 1 from the real syscall, and on Linux, where it returns null.
vp run check:changed passes for the stack.
Runtime on Linux: Force stop from the list killed exactly the chosen agent and left the other two running.

Evidence (web)

No load was generated on nucbox-1. For the capture only, an uncommitted two-line patch pointed the PSI reads at a fixture file holding severe readings (host full avg10=6.4, agents full avg10=84.7). The agents, their scopes and memory.current, the stream, and the UI are all real.

Before (main): nothing tells the user agents are starved	After: sidebar warning naming the heaviest agents, with Force stop
Before: main shows a frozen agent as plain Working, with no memory warning	After: Low on memory popover listing three agents with their thread titles, sizes and Force stop

Limits

The mobile banner is not captured; Metro on nucbox-1 was ruled out while it hosts the live server.
Heaviest agents need systemd scopes, so on macOS and Windows only the level shows.
Real pressure behavior is verified on the separate VM.

Walkthrough

The server samples Linux and macOS memory pressure and streams updates to opted-in clients. Client state retains and projects those updates. The web and mobile interfaces display severe-pressure warnings with agent memory details and conditional thread and force-stop actions.

Changes: Memory-pressure reporting

Layer / File(s)	Summary
Pressure contracts and agent-scope shape `packages/contracts/src/*`, `packages/shared/src/AgentScope.ts`	Contracts define pressure levels, agent memory details, subscription options, and update events. `AgentScope` exposes control-group information for agent scopes.
Agent control-group discovery `apps/server/src/process/agentScope.ts`, `apps/server/src/process/agentScope.test.ts`	`AgentScope` reads matching systemd scope directories and associates tracked thread IDs. Tests cover unavailable data and owned agent and shared scopes.
Host pressure sampling and classification `apps/server/src/resourceTelemetry/HostResources.ts`, `apps/server/src/resourceTelemetry/HostResources.test.ts`, `apps/server/src/resourceTelemetry/NativeTelemetryClient.ts`, `native/resource-monitor/src/main.rs`, `apps/server/src/server.ts`	`HostResources` samples Linux PSI or macOS pressure, classifies pressure levels, and reports up to three high-memory agents when pressure is active. The native monitor supplies macOS pressure readings. Tests cover parsing, rounding, classification, and sidecar sampling.
Subscription, replay, and client projection `apps/server/src/environment/ServerEnvironment.ts`, `apps/server/src/ws.ts`, `packages/client-runtime/src/rpc/session.ts`, `packages/client-runtime/src/rpc/session.test.ts`, `packages/client-runtime/src/state/server.ts`, `packages/client-runtime/src/state/server.test.ts`, `packages/client-runtime/src/state/serverConfigProjection.ts`, `packages/client-runtime/src/state/serverConfigProjection.test.ts`, `apps/mobile/src/connection/runtime.ts`, `apps/mobile/src/state/server.ts`, `apps/web/src/connection/runtime.ts`, `apps/web/src/state/server.ts`	The server advertises the capability and streams updates to opted-in subscribers. Client sessions retain pressure events for replay, and config projections preserve pressure across capable snapshots and clear it when the level is `none`. Mobile and web connections enable the subscription.
Web and mobile pressure warnings `apps/mobile/src/features/home/HomeScreen.tsx`, `apps/mobile/src/features/home/MemoryPressureBanner.tsx`, `apps/web/src/components/sidebar/SidebarChrome.tsx`, `apps/web/src/components/sidebar/SidebarMemoryPressureWarning.tsx`	The mobile home header and web sidebar display warnings for severe pressure. Agent rows show memory use and provide thread links and conditional force-stop actions.

Full details: Description check

Explanation

The description follows the required template: it has Problem, Fix (Change), Verification, and Limits sections, and it states the problem, the approach, and the test results. Scope and approval is missing. The description does not link a triaged issue or a maintainer-approved discussion, and it does not explain why the change qualifies for an exemption. The PR adds a new capability, so the template requires that approval. Verification is detailed and includes test names, a macOS sidecar run, a Linux runtime check, and before/after screenshots. The mobile banner was not captured, and the author states this. The description also omits a conventional commit title, which the template requests in its header comment.

Resolution

Add a "Scope and approval" section. Link the triaged bug issue or the discussion with explicit maintainer approval of this direction, including the approval comment. The PR adds a new feature (memory-pressure reporting and warnings for web and mobile), so a simple exemption does not apply. Consider adding a conventional commit title in plain language, such as "feat(server): show when the host is short on memory". If you want the mobile banner covered by evidence, add a screenshot or state the gap clearly again in Verification.

Exclude memoryPressure from the persisted config cache.
persist strips environmentThemes, usageLimitSources, and lastEventLoopStall before it calls cache.saveServerConfig. It does not strip memoryPressure. The live projection now stores memoryPressure in config. The server sends a new payload each time the level or a rounded agent memory value changes. Each change fails sameCacheValue and triggers a cache write.
The load path calls withoutEnvironmentThemes, which drops memoryPressure. The cached value is never read back. The result is repeated writes of transient data while memory pressure is active, including on mobile storage.
Add memoryPressure to the destructuring.

Do not carry pressure across a server-version change.

The config projection survives session replacement, and subscribe delivers the replacement server's snapshot to it. The snapshot branch currently carries the previous memoryPressure unconditionally. If the replacement is an older server with no pressure events, the severe warning can remain visible for the lifetime of that projection.

Retain pressure only when the snapshot has the same server version.

JJulius Marminge2d ago

Valid, fixed in 7586be0d5b. Rather than comparing server versions, the snapshot branch carries memoryPressure only when the replacement server advertises capabilities.memoryPressure: a server that sends the event replays the current level on subscribe, and one that doesn't would never clear it. The existing projection test now also reconnects to a snapshot without the capability and expects the pressure to be dropped; it failed before the change. #27254 applies the same gate to quietRuns.

CcoderabbitaiBot1d ago

@juliusmarminge The capability check is more precise than comparing server versions. The supplied code carries memoryPressure only when capabilities.memoryPressure === true, so a replacement server without the capability drops the previous pressure. This addresses the stale-warning finding.

@coderabbitai Re the outside-diff Minor at packages/client-runtime/src/state/server.ts:433-438 (exclude memoryPressure from the persisted config cache): valid, fixed in 165f23076b. persist now strips memoryPressure with the other live-only fields, so pressure changes no longer write to the cache. The existing "shows a reported stall but never caches it" test now puts pressure in the live snapshot and asserts the saved config omits it; it failed before the change. #27254 (6611a2c1e8) strips quietRuns the same way, with the same assertion.

The inline serverConfigProjection.ts finding from that review was fixed earlier in 7586be0d5b (the thread is resolved).

Intentionally not gated. Releases build the resource monitor from the same commit as the server and bundle it into both the desktop app and the CLI archive (release-desktop.yml, scripts/build-cli-archive.ts), so a shipped server never talks to an older protocol-3 sidecar. The only mismatch is a developer's stale local build under native/resource-monitor/target/ on macOS, and rebuilding it fixes that. We had a hello capability check here and removed it as unneeded.

Not needed: AgentScope is a Context.Reference with a default value (packages/shared/src/AgentScope.ts), so a layer that doesn't provide it gets the no-op default. The test runs and passes under the server test command; CI passed all 33 checks on 0454218295 with it.

@juliusmarminge You’re right. I confirmed that AgentScope is a Context.Reference with a no-op defaultValue in packages/shared/src/AgentScope.ts, Line 63. The test uses that default when no layer provides it.

Keep the previous level when the macOS reading fails.

The sidecar processes commands on a single thread, so a slow collector.sample can delay the memoryPressure reply. If the reply takes longer than 1 s, memoryPressureLevel fails with NativeTelemetryRequestTimedOut. Line 126 turns that failure into null. When every sample field is null, nextMemoryPressureLevel returns "none". A host that was severe then drops to none for one cycle, and the warning and Force stop option disappear. This is the situation the feature exists for. The same applies to any Linux read failure.

Return previous when no signal was read. A host without PSI stays at none.

Valid, fixed in 8f206f69da. nextMemoryPressureLevel now returns the previous level when no signal could be read (a sidecar timeout or an unreadable PSI file), so a severe host no longer drops to none for a cycle. A host that never has these signals still stays at none. Your suggested row is in the existing table (previous severe, all-null sample, expect severe); it failed before the fix.

CcoderabbitaiBot1d ago

@juliusmarminge The supplied code confirms that nextMemoryPressureLevel returns previous when all signals are null. This preserves severe after a failed read and keeps an unsupported host at none. Thanks for adding the regression case.

Rank agents before rounding their memory.

When four agents have different memory usage within one rounding step, roundAgentMemory gives them the same value. The sort can then retain the first three scope entries and omit the agent using the most memory. Sort and select by the raw memory.current value, then round the selected values for display.

Valid, fixed in 2842f1749c. Ranking moved into an exported heaviestAgents that sorts and selects by exact memory.current and rounds only the three it keeps. A new test has four agents that all round to 3,328 MiB, with the largest last in scope order; it expects the three largest. It failed with rounding before ranking.

This consumes an Effect service, so please import its module as a namespace (import * as NativeTelemetryClient from "./NativeTelemetryClient.ts") and acquire NativeTelemetryClient.NativeTelemetryClient below. Named imports are reserved for pure helpers, schemas, errors, configuration, and types.

Effect Service Conventions: GitHub attached only two of the four submitted inline comments. The findings are:

apps/server/src/resourceTelemetry/HostResources.ts:9,22: import the AgentScope and NativeTelemetryClient service modules as namespaces and acquire their qualified service tags.
apps/server/src/orchestration-v2/ThreadManagementService.ts:45: import AgentScope as a namespace and acquire AgentScope.AgentScope.
packages/contracts/src/orchestrationV2.ts (OrchestrationV2ForceStopThreadError): split the superseded failure into a separate tagged error because its discriminator selects the caller-visible message; update construction sites and the RPC error union while preserving both messages.

These fixes span imports/usages or multiple error declarations and consumers, so no self-contained suggestion is included.

Adversarial review follow-up (c2ee4be):

Dropped hostStallPercent/agentsStallPercent from the payload. They changed almost every 5 s sample and no client read them, so every client re-rendered on every sample. A none update with nothing stored now leaves client config identity alone.
The level now falls back to none after 30 s with no readable source (a dead macOS sidecar), instead of keeping severe indefinitely.
Rebased on main now that #27252 has merged. Its restart-path follow-up is a separate PR: #27800.
