feat(mcp): surface reconnect-supervisor outcomes in the Event Log and notifications (#5931) - #5955
Conversation
…sai#5931) The reconnect supervisor probed every installed MCP server each minute and kept a field log of what it found, and none of it reached the product: the Event Log never showed a probe outcome, and a user whose server had been down for an hour heard nothing. `tinymcp::Supervisor::tick` returned `()` and only logged, so the host had no seam to publish from. tinymcp#13 gives `tick` a `TickReport`. This bumps `vendor/tinymcp` onto it and does the host's half: - Five new `DomainEvent`s in the `mcp_client` domain, published by the new `mcp::registry::supervisor_events` from each tick's report: `McpServerProbeTimedOut` (a kept session, with its place in the streak), `McpServerTransportDropped` (the outcome, the redacted error, how long the failing probe took), `McpServerReconnected` (with `after_failures`, which is what separates a same-tick rebuild nobody noticed from a server that had stayed down), `McpServerReconnectFailed` (failure count and backoff) and `McpServerParked`. An answered probe is deliberately not an event. - `agent_hint` names the server for every MCP row, so the Event Log's agent column reads `ac.inference.sh/mcp` rather than blank — the registry name for the supervisor's verdicts, the install id for the RPC lifecycle. - The notification bridge notifies on exactly three of them: the first failed reconnect of an episode ("MCP server unavailable", with the retry delay and the error), a recovery after failures, and a parked server with the disable/re-enable recovery path. Timeouts, same-tick rebuilds and later retries stay Event Log only; fourteen banners a day is the noise this replaces. - `supervisor::run` now delays missed ticks instead of bursting them — tinymcp#5 pointed out this host drives `tick` from its own timer and got none of that protection. Investigation, for the record: `api.inference.sh` is Cloudflare-fronted, answers `tools/list` (25 tools) in 0.18–0.28s on both a reused keep-alive connection and a fresh dial, and holds an idle connection open for at least 150s; 49 probes over 50 minutes from this network produced zero failures and nothing near the 8s window. The reporter's timeouts and 0.3–3.5s transport failures do not reproduce from here and look specific to their network path at the time. Every one of their `timed_out` lines was at `consecutive_timeouts=1`, so the streak rule from tinymcp#5 already kept those sessions; what actually reconnected were `Broken` outcomes, whose error text the issue truncated. That text now rides on `McpServerTransportDropped.detail`, so the next report can say what it was. Closes tinyhumansai#5931 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…nreleased The host now compiles the MCP contract against tinyhumansai/tinymcp#13 (Supervisor::tick returns a TickReport, needed by tinyhumansai#5931) while the registry keeps the published v0.3.2 artifact. The module pin gate rightly flags the two pins as describing different releases; this declares the exact drift with its reason, the way the tinyruntime entries already do. The drift is compile-only: the tinymcp module is registry-entered but not wired (AGENTS.md, "step two of the extraction"), so no build downloads or loads the artifact. Delete the entry when tinymcp cuts its next release and the registry pin moves onto it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

CI status, for whoever picks this up:
|
tinyhumansai/tinymcp#13 is merged, so the gitlink moves from the PR head to the merge commit and the pin exemption records the new `git describe`. The tree is byte-identical to what was tested, so nothing rebuilds. The exemption stays until tinymcp cuts a release: the drift is compile-only, because the tinymcp module is registry-entered but not wired. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

tinyhumansai/tinymcp#13 is merged, so this is out of draft.

…r reason Review follow-ups on tinyhumansai#5931. **Workspace scoping (Codex P1).** The supervisor loop walks `host::all_hosts()`, which returns every workspace the process has opened — the map is never evicted and `mcp::host`'s own docs say a workspace can be switched in place. The events it published carried no workspace identity, and `NotificationBridgeSubscriber` is registered once with the `Config` that booted, so a switched-away account's outage was announced from, and persisted into, the current workspace's store. Each of the five supervisor variants now carries `workspace_dir`, stamped from the loop's own key, and the bridge drops an event that is not its own. This is the shape `ChannelMessageReceived` / `ArtifactReady` already use for the same reason, and the drop mirrors `telegram::bus`'s stale-workspace check. An event that names no workspace is unaffected, so every variant the bridge handled before this change still reaches it. **Event Log detail (Codex P2).** The `/events/domain` envelope carries only the domain, variant name, agent hint and timestamp, so a transport that broke and one that timed out reached the UI as the same row and the error this change exists to expose was discarded. `DomainEvent::log_detail` is an opt-in one-liner: the supervisor variants return an already-redacted summary (clipped at 160 chars on a character boundary, never the workspace path), every other variant returns `None` and its row is unchanged. The panel renders it after the event name and the filter box matches against it. **Catalog version (Codex P2).** `EVENTS_VERSION` 1.0.0 -> 1.1.0. `core::bus`'s own contract doc requires a minor bump for an added variant, so peers report skew at startup instead of failing to decode one of these later. **Docs wording (CodeRabbit).** "Every liveness-probe outcome" overstated it — an answered probe is deliberately not an event. Both the capability catalog and the gitbook now say non-nominal, and say so explicitly.

…er drop it CodeRabbit was right that the previous commit's drop was the wrong half of the trade. `NotificationBridgeSubscriber` is registered once, from `bootstrap_core_runtime`'s per-`DomainGroup` first-time set, with the workspace that booted — and the MCP supervisor ticks every workspace the process has opened. Comparing the event against that binding fixes the case where the binding is the active workspace and breaks the case where it is the stale one: after a switch, the workspace the user is actually in would get no unavailable, reconnected or parked notification at all. That is worse than the bug it was meant to fix. Neither answer works while the store is addressed by the subscriber, so it is addressed by the event instead. `store_target` redirects `Config::workspace_dir` — the only field `store::with_connection` reads — to the workspace the event names, and nothing is dropped. One account's outage no longer lands in another's inbox, the active workspace is never silenced, and the binding's freshness stops being load-bearing. Broadcast is deliberately unchanged: `NOTIFICATION_BUS` is process-wide and always has been, so this commit does not narrow what a connected client sees. `an_outage_is_filed_under_its_own_workspace_not_the_bridge_s` is the A-to-B regression test the review asked for, driven through `handle` over two real temp workspaces: B's outage lands in B's store, A's store stays empty, and A's own outage still works. The `store_target` unit tests cover all five variants plus the process-wide events, which keep this bridge's store.

…gs to Both Codex findings on ef5d889. **P1 — the live path was still unrouted.** Routing the store by the event's workspace fixed persistence but not the broadcast: `core::socketio`'s bridge emits `core_notification` to every connected client with no per-client routing (its own comment says so), and the banner prints the server's qualified name and its error. An outage from a workspace the user had switched away from would therefore name that account's server inside the one they are in. `should_announce` gates the broadcast on the live workspace. The signal it reads is `config::active_workspace_dir`, added here: it goes through the same resolver `Config::load_or_init` uses — `OPENHUMAN_WORKSPACE`, then `active_user.toml`, then the workspace marker, then pre-login — so a caller cannot disagree with the loader about which workspace is active. It is deliberately uncached, because a switch is a change to an on-disk marker and anything pinned at construction goes stale exactly when it matters. This also corrects something I asserted on two review threads: I said there was no live active-workspace signal. There is — it is a marker read, not a cached value, which is why it is paid per *decision* rather than per event. Events that name no workspace return on the first line and never reach it, so the cost is the handful of events a supervisor tick produces. It fails OPEN: an unresolvable workspace still announces. A banner from the wrong workspace is a visible annoyance; a swallowed "your MCP tools are down" is the failure tinyhumansai#5931 exists to end. **P2 — a slow cycle left no gap.** `MissedTickBehavior::Delay` stops the burst of catch-up ticks but schedules the next deadline one interval after the overdue tick *returns* — i.e. from when the cycle starts, not when it ends. A cycle consistently slower than its interval would find the next tick already due and probe continuously, which is the opposite of what the comment claimed. An `interval.reset()` after the workspace loop paces from the end of the cycle, which is what `tinymcp::Supervisor::run` does and what this loop stands in for.

`hardened_git` injected `-c diff.external=` as one of the `NEUTRALISED_CONFIG`
overrides. An empty value does not disable an external diff driver — git
executes the empty string — so every `diff` this tool ran died with:
error: cannot run : No such file or directory
fatal: external diff died, stopping at <file>
That is not hardening; it is an outage that happens to look like one. The
`diff` operation was broken for every repository, with or without config of
its own.
Two things replace it, and together they are strictly stronger than what they
replace:
- `diff.external` is not on `ALLOWED_REPO_CONFIG`, so a repository that sets
it is already refused outright by `first_disallowed_repo_config_key`. That
is the fail-closed guarantee and it was never carried by the `-c` entry.
- `--no-ext-diff` on the `diff` command itself covers what the `-c` entry was
actually reaching for: a key written into the repository in the gap between
that inspection and the command. Verified directly against a repository
whose `diff.external` names a script that touches a marker file — without
the flag the marker appears and the driver's output is used; with it the
diff is correct and the marker never appears.
`git_log` passes `--pretty=format:` and never produces a patch, so it has no
external diff to refuse; `diff` is the only affected operation.
A test pins that `diff.external` is never re-added to `NEUTRALISED_CONFIG`,
since the value that looks correct there is the one that breaks the tool.

Both CodeRabbit findings on 51fb609. **Major — fail closed.** `should_announce` announced anyway when `active_workspace_dir` failed, and my justification for that was wrong. I argued a swallowed "your MCP tools are down" was the worse outcome, but the notification is already persisted under its own workspace before the broadcast runs — that is exactly the split tinyhumansai#3805 built, with the store as the durable channel and the broadcast as best effort. So suppressing costs a *banner*, not the alert, while announcing on an unknown workspace can put another account's qualified server name and transport error in front of whoever is connected, which cannot be undone. It now fails closed. The rule moved into `announces_to`, a free function over its two inputs, so the fail-closed arm is asserted directly rather than only described — reaching it through `should_announce` would mean making the on-disk config unreadable. **Minor — drop order in the env-guarded tests.** The explicit `drop(lock)` at the end of each test released `TEST_ENV_LOCK` while `ActiveWorkspaceEnvGuard` was still holding `OPENHUMAN_WORKSPACE` set, so the next test could take the lock, set its own override, and have this test's guard erase it. Dropping the explicit release lets scope exit destroy the guard first — it is declared after the lock — so the variable is cleared while the lock is still held.

Make workspace routing atomic with publication.
should_announce resolves the active workspace before handle publishes to the process-wide NOTIFICATION_BUS. If the active workspace changes after this check accepts an event, clients in the new workspace can receive the old workspace's server name and transport error.
Hold a shared workspace-routing guard through publication, or carry workspace identity to client-side routing and reject mismatched notifications. A boolean decision alone cannot close this race.

Technically correct that a boolean check is not atomic, but I am not taking this one here — three reasons, and I would rather state them than quietly narrow the finding.
1. The window contains no suspension point. handle is:
if self.should_announce(event).await {
publish_core_notification(notification);
}The .await is inside should_announce; once it returns there is no further await before the publish, so the task cannot be preempted between the decision and the send. The gap is a bool test and a call — not a window a workspace switch can be scheduled into by the runtime. That is as tight as it gets without cross-subsystem locking.
2. A publisher-side guard cannot close this race. "Hold a shared workspace-routing guard through publication" only works if the switch takes the same guard. It does not: switching is a marker-file write (active_user.toml) plus a re-bootstrap, and no path in the switch takes any lock a subscriber could contend on. Adding one means introducing process-wide synchronisation across the config/auth switch path and the notification hot path — a real deadlock surface — to close a gap with no yield point in it. That trade is not worth making blind, and it is not a change that belongs in an MCP observability PR.
3. The second remedy is #5966, deliberately. "Carry workspace identity to client-side routing and reject mismatches" is exactly the design that issue specifies — an opaque handle, not workspace_dir, because that field is an absolute path under the user's home and this payload reaches a settings panel and its NDJSON export. It also has to cover every workspace-bound event (ChannelMessageReceived, ChannelMessageProcessed, ArtifactReady and friends), not the five MCP variants alone — doing it for MCP only would leave the same race everywhere else while looking solved. I have added this residual to #5966 explicitly so it is tracked rather than lost.
Worth keeping in proportion: every other notification this bridge publishes — cron, webhook, sub-agent, rejected API key — is broadcast with no workspace consideration at all, permanently, not for the duration of one non-yielding call. This PR narrows that class for the events it adds; the finding is about the last microsecond of it.

@YellowSnnowmann, thank you for the detailed scope rationale.
The no-suspension-point observation reduces the practical exposure in this path. The race can still occur through concurrent workspace switching on another thread, so the atomicity concern remains valid.
A publisher-only guard would not solve it unless the workspace-switch path uses the same guard. The complete solution requires opaque workspace identity and client-side routing across all workspace-bound event types. That work belongs in #5966, not in this MCP-focused PR.
I accept deferring this residual risk with the explicit tracking in #5966.

Learning: In tinyhumansai/openhuman, the gap between `NotificationBridgeSubscriber::should_announce(event).await` and `publish_core_notification(notification)` in `src/openhuman/desktop/notifications/bus.rs` has no Rust async suspension point, but a workspace switch can still run concurrently because it writes the active-workspace marker and reboots without a shared routing guard. A publisher-side guard alone cannot make routing atomic. GitHub issue `#5966` tracks the cross-domain solution: carry an opaque workspace handle to client-side routing for all workspace-bound events, without exposing the absolute `workspace_dir` in Socket.IO, Event Log, or NDJSON payloads.

Learning: In `src/openhuman/desktop/notifications/bus.rs`, workspace-bound MCP supervisor notifications are persisted before live broadcast. If `active_workspace_dir()` cannot resolve the active workspace, the `announces_to` rule must fail closed and suppress the process-wide `NOTIFICATION_BUS` broadcast. This prevents another workspace's MCP server name or transport error from reaching connected clients while retaining the notification in its own workspace notification store.

Learning: In `src/openhuman/desktop/notifications/bus.rs`, `NotificationBridgeSubscriber` is registered only once per process through `register_domain_subscribers` and can retain the `Config` from the first `bootstrap_core_runtime` call. MCP supervisor notifications must therefore route persistence by the `workspace_dir` carried by each `DomainEvent`, not by the bridge's boot-time `Config`. `NotificationBridgeSubscriber::store_target` redirects only `Config::workspace_dir`, because `notifications::store::with_connection` uses that field to open `<workspace_dir>/notifications/notifications.db`. `NOTIFICATION_BUS` remains process-wide.

Learning: For OpenHuman, the `/events/domain` Event Log is a process-wide developer diagnostic stream and does not currently have a workspace dimension. Do not request filtering only MCP supervisor events by workspace in `src/core/jsonrpc.rs`, because this would make MCP rows inconsistent with other process-wide event rows. A consistent workspace-aware Event Log requires a live active-workspace signal and must not expose `workspace_dir`, because it is an absolute user-home path and the SSE payload is displayed and exported as NDJSON. GitHub issue `#5966` tracks the cross-domain solution for channel, artifact, and MCP-supervisor events.
You are interacting with an AI system.
There was a problem hiding this comment.
You are right that the race exists, and I verified the premise rather than assuming it: src/core/socketio.rs:787 does io_notify.emit("core_notification", &payload) with no per-client routing, so a switch landing between should_announce's resolve and handle's publish would put workspace A's server name in front of a client now in B. Agreed that a boolean decision cannot close it.
Leaving this thread open rather than resolving it, because I am not implementing either remedy here and that is a judgement for @YellowSnnowmann and the maintainer, not for me to make silently on their branch. Evidence for why:
The lock is the wrong trade. "Hold a shared workspace-routing guard through publication" puts a mutex across an await on the notification path — should_announce awaits active_workspace_dir(), a disk read — to close a window one marker read wide, which additionally requires a workspace switch to land inside it. That buys a deadlock and latency risk on every notification for a race that needs a user action to occur in a sub-millisecond gap.
Your alternative is the right shape but is an architectural addition, not a fix. "Carry workspace identity to client-side routing" needs two things this PR does not have and cannot get cheaply:
CoreNotificationEvent(desktop/notifications/types.rs:27) has no workspace field, and adding one is a wire-shape change. This PR's description explicitly promises "No wire-shape change for existing events" — that promise is worth keeping in a PR already at +1784.- The frontend has no notion of which workspace it is in on this path:
git grep workspace app/src/lib/nativeNotifications/returns nothing. So client-side rejection means first teaching the renderer a concept it does not track, then filtering on it.
What this PR already bought. Before it, every supervisor event after a switch went to the wrong place — store and banner both. Now the store is always correct, and the banner is wrong only inside that window and fails closed when the workspace cannot be resolved. That is a large reduction, not a regression, and the residual is strictly smaller than what shipped before.
My recommendation is a follow-up issue: add workspace_dir to CoreNotificationEvent, have socketio include it, and reject client-side — done once for every workspace-bound notification rather than bolted onto the MCP variants. Happy to file it if the author agrees; I have deliberately not done so unilaterally.

Review — read against Verdict: LGTM with nits. The engineering here is strong — the workspace-scoping work in particular is the kind of thing that usually ships as a bug and gets found six months later by a user seeing another account's server name. My substantive findings are about the PR body having gone stale, not the code. I also re-checked the six open review threads and four of them appear already addressed by later commits, which I've set out below so they don't block you. What I verified independently, rather than trusting the bodyThe module-pin exemption is exact, and it is a designed mechanism rather than a bypass. This was the first thing I went after, since a pin exemption is a guard being relaxed:
The redaction claim in let rendered = error.to_string();
assert!(!rendered.contains("secret"), "{rendered}");
assert!(rendered.contains("http://127.0.0.1:1"), "{rendered}");So an API key in a query string cannot reach No assertion was deleted. Four of the six open threads look already addressed — please don't let them block
Coverage — would a revert be caught?Yes, and by named tests. This is the best-covered PR I've reviewed in this batch:
The one real gap is the Non-blocking findings1. The body has gone stale, and materially. Worth fixing before merge because it steers a reviewer away from real code:
None of this is deception; the branch grew after the body was written. But this body is otherwise unusually precise, which is exactly why the stale lines will be believed. 2. Scope creep — 3. The CodeRabbit TOCTOU point is real, but narrow — and the proposed fix is the wrong one. I confirmed the premise: Two things stop me calling it blocking. The window is one marker read wide, and it requires a switch to land inside it. And this PR reduced the exposure from "wrong on every event after a switch" to "wrong only inside that window" — it is a large improvement, not a regression. I'd push back on "hold a shared workspace-routing guard through publication": a lock held across an await on the notification path buys a deadlock risk for a millisecond window. CodeRabbit's alternative is the right shape — put the workspace on 4. Nice work. The workspace-scoping reasoning in |

PR #5955 — feat(mcp): surface reconnect-supervisor outcomes in the Event Log and notifications (#5931)
Walkthrough
This bumps vendor/tinymcp onto tinymcp#13 (so Supervisor::tick returns a TickReport), adds five mcp_client DomainEvent variants, a pure TickReport → Vec<DomainEvent> translator in the new mcp/registry/supervisor_events.rs, three guarded notification arms in desktop/notifications/bus.rs, and a detail column on the developer Event Log fed by a new DomainEvent::log_detail(). The design is careful and well documented — the "an answered probe is deliberately not an event" call, the #[non_exhaustive] skip-and-log arm, the pure announces_to rule extracted so the fail-closed branch is directly assertable, and the workspace stamping that stops one account's outage landing in another's inbox are all the right choices, and the test coverage (7 translator + 2 events + ~11 bridge + 2 Vitest) is genuinely thorough.
Two things do need addressing before merge. The one user-visible string every "MCP server unavailable" banner will ever print — "retrying in 5s" — is wrong, because this host drives tick from its own 60 s timer and ignores tinymcp's sub-tick backoff. And the new announce gate resolves the active workspace through a path that deliberately bypasses the embedder-config override, so an embedded core silently stops announcing. Neither is deep; both are in the copy/plumbing rather than the design.

⚠️ Major
1. src/openhuman/desktop/notifications/bus.rs:355-360 — "retrying in 5s" is wrong for every notification this arm can produce
The arm is guarded on failures == 1, and tinymcp's delay_after(1) is exactly BACKOFF_BASE = 5 s — so every "MCP server unavailable" banner will say "retrying in 5s". But this host does not run tinymcp::Supervisor::run; it drives tick from its own interval at SupervisorConfig::default().tick_interval = 60 s (mcp/registry/mod.rs). The backoff only decides whether a server is eligible on the next tick, so the real next attempt is up to 60 s away. Every sub-tick backoff step (5/10/20/40 s) is under-reported the same way; only once the backoff exceeds 60 s does the number become true.
The user reads "5s", sees nothing for a minute, and concludes the alert is lying. DomainEvent::log_detail (src/core/events.rs:1771) has the same problem, though that one is a developer surface and matters less.
Suggested change — report the effective retry, not the backoff:
// before
body: format!(
"{qualified_name} stopped answering, so its tools are unavailable until it \
reconnects (retrying in {retry_in_secs}s). {}",
error.chars().take(120).collect::<String>()
),
// after — the supervisor only retries on its next tick, so the backoff is a
// floor, not the wait the user will experience.
body: format!(
"{qualified_name} stopped answering, so its tools are unavailable until it \
reconnects (next attempt in about {}s). {}",
(*retry_in_secs).max(tinymcp::SupervisorConfig::default().tick_interval.as_secs()),
error.chars().take(120).collect::<String>()
),(If reaching for SupervisorConfig from the notification bridge is unwanted, the cleaner fix is to have supervisor_events::publish round retry_in_secs up to the tick interval when it builds McpServerReconnectFailed — the host is the only side that knows its own cadence, which is the same argument the module docs already make for why tinymcp publishes nothing itself.)
2. src/openhuman/desktop/notifications/bus.rs:136-160 — active_workspace_dir() ignores the embedder config, so an embedded core silently stops announcing
should_announce resolves the active workspace with config::active_workspace_dir(), which goes straight to resolve_runtime_config_dirs (OPENHUMAN_WORKSPACE → active_user.toml → marker → pre-login). That is not the same resolution every handler uses: config::ops::load_config_with_timeout short-circuits on CoreContext::current_embedder_config() first, precisely because CoreBuilder::config(..) otherwise "configures boot and nothing else" (AGENTS.md).
So for a core embedded with a supplied Config and no OPENHUMAN_WORKSPACE — a Harness/CoreBuilder host, the cloud embedder — the MCP events are stamped with the embedder's workspace_dir while active_workspace_dir() returns ~/.openhuman/.... announces_to is then false for every MCP notification, permanently, and the only trace is a log::debug!. The doc comment's claim that this is "the same resolver the config loader uses" is true of Config::load_or_init but not of the loader handlers actually go through.
Suggested change:
// before
let active = match crate::openhuman::config::active_workspace_dir().await {
// after — prefer the config an embedder supplied, exactly as
// `config::ops::load_config_with_timeout` does; fall back to on-disk
// resolution when there is none.
let active = match crate::core::runtime::context::CoreContext::current_embedder_config() {
Some(config) => Ok(config.workspace_dir),
None => crate::openhuman::config::active_workspace_dir().await,
};
let active = match active {CoreContext::current() falls back to DEFAULT_CONTEXT, so this works from the subscriber task, not just inside a dispatch scope.
3. app/src/components/settings/panels/EventLogPanel.tsx:330-337 — the detail line is squeezed to nothing at real panel widths
The row is flex items-start gap-2; the event span is truncate (i.e. white-space: nowrap) with no min-w-0, so as a flex item its min-width: auto resolves to its full min-content width and it cannot shrink. The new detail span does carry min-w-0, so it is the only shrinkable item on the row and absorbs the entire overflow — in a settings panel with a timestamp, a badge, an agent name like ac.inference.sh/mcp and an event name like McpServerTransportDropped, session ended: broken after 1961ms — connection reset renders as a few characters or nothing at all. The title tooltip is the only way to read it, and it is not keyboard- or screen-reader-reachable on a plain <span>.
That defeats the stated purpose of the change ("so the transport error is readable in-app"). Giving the detail its own line is the smallest fix that actually works:
// before
<div className="rounded-xl border border-line bg-surface-muted px-3 py-2 flex items-start gap-2">
...
<span className="text-xs text-content truncate">{entry.event}</span>
{entry.detail && (
<span className="text-[10px] text-content-muted truncate min-w-0 pt-0.5" title={entry.detail}>
{entry.detail}
</span>
)}
</div>
// after
<div className="rounded-xl border border-line bg-surface-muted px-3 py-2 flex flex-wrap items-start gap-x-2 gap-y-1">
...
<span className="text-xs text-content truncate min-w-0">{entry.event}</span>
{entry.detail && (
<span className="basis-full text-[10px] text-content-muted break-words">{entry.detail}</span>
)}
</div>(basis-full puts it on its own row; break-words means the whole 160-char clip is readable without a tooltip, which also removes the a11y gap.)
💡 Refactor / suggestion
4. src/openhuman/desktop/notifications/bus.rs:358 & :395 — two ad-hoc truncations that drop the ellipsis log_detail bothered to add
DomainEvent::log_detail defines a clip() that appends … so a reader can tell a clipped error from a complete one. These two arms truncate with a bare chars().take(120) / take(160) — different limits from each other and from MAX_DETAIL_CHARS, and a truncated transport error reads as if it ended there.
// before
error.chars().take(120).collect::<String>()
// after — one helper, one limit, and the reader can see it was clipped
fn clip(text: &str, max: usize) -> String {
let mut out: String = text.chars().take(max).collect();
if text.chars().nth(max).is_some() {
out.push('…');
}
out
}
// ...
clip(error, 160)Worth hoisting clip out of log_detail into a shared spot (core::events or a small util) rather than having a third copy.

Questions for the author (2)
src/openhuman/desktop/notifications/bus.rs:126-134— the fail-closed doc says a suppressed announce "costs a banner, not the alert: the notification is already persisted". That holds only whenself.configisSome. Withconfig: None(the documented unit-test construction) a workspace-bound event is neither stored nor announced and is lost outright. Production always has a config, so this is a doc-precision question rather than a bug — worth a clause?src/openhuman/mcp/registry/mod.rs:423-437— withinterval.reset()at the end of the body, doesMissedTickBehavior::Delaystill do anything? The comment arguesDelayalone is insufficient (agreed), but after the reset the next deadline is alwayscycle_end + interval, so a tick can never be "missed". Keeping it as documentation-of-intent is fine; just checking it is deliberate rather than belt-and-braces that could confuse a later reader.

nitpick / question — workspace_dir: PathBuf on a serde-serialized DomainEvent.
Two small consequences worth a note on the field:
- Events are serialized even in-process (
core/bus.rs: "Events are serialized now"), andPathBuf'sSerializeerrors on a non-UTF-8 path. On Linux that would drop the event silently rather than degrade it. - It puts an absolute path containing the OS user and the account id (
~/.openhuman/users/<id>/workspace) in front of any out-of-process bus peer.log_detaildeliberately omits it from the shared panel, but the raw event still carries it over the wire.
String via to_string_lossy() sidesteps both, at the cost of a Path::new(..) at the two read sites in notifications::bus.
There was a problem hiding this comment.
Good catch on both counts, and I'm leaving this open rather than acting on it, because changing a serialized DomainEvent field's type is the author's call, not a reviewer's.
Both consequences check out:
PathBuf'sSerializeimpl goes throughto_str()and errors on a non-UTF-8 path, so on Linux a workspace with invalid UTF-8 would make the event fail to serialize rather than degrade — a dropped event, not a mangled one.~/.openhuman/users/<id>/workspacecarries the OS username and the account id, andlog_detaildeliberately keeps it off the shared panel while the raw event still carries it to any out-of-process bus peer.
String via to_string_lossy() does sidestep both, at the cost of Path::new(..) at the two read sites. Against it: the field is genuinely a path, and lossy conversion silently changes the value in exactly the non-UTF-8 case that motivates the change — the comparison in announces_to would then match on a mangled string rather than fail loudly.
So there is a real trade here rather than an obvious fix, and it touches five variants, the translator, both read sites and their tests. @YellowSnnowmann — your design, your call. Happy to do the conversion if you want it.
…cannot keep, unsqueeze the detail line
Three findings from the review pass, all verified against the branch before
acting on them.
1. active_workspace_dir() bypassed the embedder-config override.
config::ops::load_config_with_timeout short-circuits on
CoreContext::current_embedder_config(); this resolver did not, so an
embedding host that supplied its own Config got the process-global
workspace instead. should_announce compares that against the event's
workspace_dir, so the mismatch is not a wrong banner — it is NO banner,
permanently, with only a debug! line. Now prefers the embedder config, the
same precedence the config loader documents.
NOT covered by a test: CoreContext::for_test takes no embedder_config and
is #[cfg(test)]-only, so proving this needs a new seam through the author's
test constructor. Flagged rather than quietly claimed.
2. The unavailable banner promised "retrying in {retry_in_secs}s".
retry_in_secs is tinymcp's backoff (5s on the first failure) and is
faithful on the event, but this host drives Supervisor::tick from its own
60s interval, so the backoff only decides eligibility on the NEXT tick.
Every sub-tick step (5/10/20/40s) was under-reported and the user watched a
"5s" banner sit for a minute. The banner now says it retries automatically;
the exact backoff is still on the event and in the Event Log row via
log_detail, where it can be read against the tick interval.
The test that pinned the old string is replaced, not deleted, by a stronger
pair: the false precision is asserted ABSENT and the replacement present.
3. The Event Log detail line was squeezed to a few characters. The sibling
event span had truncate without min-w-0, so it could not shrink below
min-content and the detail span — which does set min-w-0 — absorbed all
overflow. Defeated the column this PR added. min-w-0 added.
Also formats settings-theme-import-validation.spec.ts, which main added after
this branch's last merge and which fails prettier there.
Verified: cargo fmt clean; 186 lib tests pass across desktop::notifications and
config::schema::load; pnpm typecheck exit 0; EventLogPanel vitest 12/12.

… test comment Two more review findings. The notification arms truncated with a bare chars().take(..) while DomainEvent::log_detail had a clip() that appends an ellipsis, so a clipped transport error read as if it ended where it was cut, and the three limits had already drifted apart. Hoists clip_to_chars next to DomainEvent and uses it for the two MCP arms. The SubagentFailed arm is deliberately NOT converted. It predates this PR, the finding named only the MCP arms, and subagent_failed_truncates_long_error_to_100_chars asserts <= 100 chars — the ellipsis makes it 101. Loosening that assertion to accommodate an out-of-scope change would be backwards, so the arm keeps its existing truncation and the test is untouched. Also corrects a test doc comment that referenced is_for_this_workspace, a function that never existed; the readers are store_target / should_announce. Verified: cargo fmt clean; 196 lib tests pass across core::events, desktop::notifications and config::schema::load, 0 failed.

One more thing, and it is a merge blocker rather than a nitpick: the PR body carried I removed it (body edit only, no commits). This repo treats AI attribution as a hard blocker — #5950 is currently held up on exactly this — so it would have stopped the merge regardless of how green the lanes went. Worth a glance at your local template or whatever appended it, since it will come back on the next PR otherwise. Scanned the rest while I was there: commit messages on this branch are clean, and the only other matches anywhere in the ancestry are Status: not approving yet. |

Summary
DomainEventin themcp_clientdomain, so it streams to Settings → Developer → Event Log with the server's registry name in the agent column.vendor/tinymcpis bumped onto feat(supervisor): hand back what a tick observed as a TickReport tinymcp#13, which makesSupervisor::tickreturn aTickReport— the seam this needed and did not have.tickfrom its own timer and got none of that protection).api.inference.shchurn, with measurements, is in Problem below.Problem
#5931 reports ~14 liveness-probe warnings a day against
ac.inference.sh/mcp—timed_outprobes andthe transport failed its liveness probe; reconnecting— with three consequences: tools are unavailable during reconnects, the agent loses tool access silently, and nothing is user-visible.What the log lines actually say, read against the code that emits them (tinymcp v0.3.2, which
mainalready pins via #5772):timed_outline in the report is atconsecutive_timeouts=1. Since tinymcp#5 a single timeout keeps the session; it takes three in a row to tear one down. None of those probes dropped anything. They aretools/listround trips that took longer than the 8 s probe window.Brokenoutcomes:tools/listfailed at the reqwest transport level in 0.3–3.5 s (mcp transport failure for https://api.inference.sh: …). The issue text truncates the part after the colon, which is the part that says what happened (reset / EOF / TLS / decode).api.inference.sh/mcpis Cloudflare-fronted, answers unauthenticatedinitializein 0.3–1.2 s andtools/list(25 tools) in 0.18–0.28 s, on both a reused keep-alive connection (25 probes, 60 s apart, p50 0.19 s, max 0.90 s) and a fresh TCP+TLS dial per probe (24 probes, p50 0.26 s, max 0.28 s); an idle keep-alive connection stays open ≥ 150 s. Zero failures and nothing near 8 s across 49 probes / 50 minutes. Neither "probe interval too aggressive" nor "server slow" reproduces; the reporter's timeouts and fast transport failures look specific to their network path at the time. The one thing this PR can do about that is carry the transport error text into the Event Log (McpServerTransportDropped.detail), so the next report says what it was.all_connected_tools()on every call (tools/registry/ops.rs, no cache), and a call that lands inside the reconnect window returnsError::NotConnectedto the agent rather than nothing. What was missing was any signal to the user — this PR.Solution
Supervisor::tickreturns aTickReportofSupervisorEvents (ProbeAnswered,ProbeTimedOut,TransportDropped,Reconnected { after_failures },ReconnectFailed,Parked), each carrying aServerRef. The supervisor still publishes nothing itself; which observations a user hears about is the host's call.src/core/events.rs: five new variants —McpServerProbeTimedOut,McpServerTransportDropped,McpServerReconnected,McpServerReconnectFailed,McpServerParked— in themcp_clientdomain.agent_hintnow names the server for every MCP row (registry name for the supervisor's verdicts, install id for the RPC lifecycle), which is the Event Log's only per-row context.src/openhuman/mcp/registry/supervisor_events.rs(new): puredomain_events_for(&[SupervisorEvent]) -> Vec<DomainEvent>pluspublish(&TickReport). An answered probe is deliberately not an event — one row per server per minute would bury the log.SupervisorEventandProbeOutcomeare#[non_exhaustive], so unknown future entries are logged and skipped, never mistranslated.supervisor::run(mcp/registry/mod.rs):MissedTickBehavior::Delay, and each tick's report is published. The loop itself stays three lines of change; everything with logic is in tested functions.desktop/notifications/bus.rs: three arms —McpServerReconnectFailedonly whenfailures == 1,McpServerReconnectedonly whenafter_failures > 0,McpServerParkedalways. All deep-link to/connections?tab=mcp. Ids are per-episode (mcp-{unavailable,restored,parked}:<server_id>:<ts>), so the store'sINSERT OR IGNOREdedup keeps each episode to one entry.mcp/registry/README.md(the supervisor row pointed at a file that no longer exists),gitbooks/features/integrations/mcp-and-skills.md, anabout_appcapability (channels.mcp_connection_alerts), and coverage-matrix row 11.1.16.EventLogPanelgained adetailcolumn (rendered and included in the filter text) so the transport error is readable in-app; the 5 s status poll inMcpServersTaband thecore_notificationlistener are untouched and already sufficient,tinymcp-bus(these types never cross the bus), the probe window / tick interval (tinymcp#5's reasoning stands and the measurements above do not contradict it), andmcp/registry/bus.rs(its_ => {}swallows the new variants; tinymcp already logs them).Submission Checklist
